The bridge or roadway may also include a parapet or parapets located on the outer edges of bridge or road surface to protect pedestrians from traffic and maintain traffic on the bridge. Some PN patients are affected exclusively within their feet and they may experience not only tingling and burning sensations within them but they may also feel stabbing pains as well. This is usually the case with nerve damage or neurological diseases that are severe and widespread within the body (systemic) or that involve conditions such as fibromyalgia. I will not be discussing “causes” for the disease specifically in this particular written work but readers can find more about causes and treatments in my companion book titled: “Peripheral Neuropathy Causes and Treatments”. To stay alive, the majority of these people will have to depend on insulin injections for the rest of their lives.
Left unchecked, these symptoms could lead to more serious medical conditions such as heart disease, cancer, and diabetes. Pounds will melt away, energy will soar, and mental sharpness will return as blood sugar stabilizes.

If you are using insulin keep extra syringes, glucagons emergency kit and urine ketone strips. The median barriers and parapets may be a “safety shape” system, which are median barriers or parapets having a profile that allows smooth mounting and demounting of a vehicle along the lower edges of the barrier or parapet. This means that physical sensations may not be the only manifestation of PN but other signs of the disease can include hypo-functioning of bodily organs (the inadequate operation of them) and even a complete failure of them in extreme cases. To my surprise, of my approximate 75 published written works, my original peripheral neuropathy book, has been my largest seller since it was published in late 2010. The emergency kit can include cold medications, antacids, cough syrup, test strips and insulin with syringes if you use one and blood glucose monitoring supplies.

Kemper, Savage, Niederbaumer, and Anthony (2005) explored differences in knowledge about diabetes among low-income persons who had varying levels of formal education. If there is a warning that diabetic people should consult their doctor before using the product, then do so.
Try also to keep the insulin in a cool place as much as possible to keep it from being damaged. The present study proposes to extend Kemper et al.’s study to examine the predictive relationship between diabetes self-management knowledge and level of formal education on depressive symptoms in low-income persons with diabetes mellitus. The outer surface has a lower edge forming an angle with, and located adjacent to, the road surface. Some species like German Shepherd, Poodles, Keeshonden and Golden Retrievers register the highest incidence of this disease.
Results may guide nurses in designing effective diabetic education for low income persons who have varying degrees of depression symptoms and varying degrees of diabetes self-management knowledge.
When a vehicle veers off the roadway and onto the safety shape median barrier or parapet, a wheel or wheels of the vehicle ride up on the lower edge of the median barrier or parapet.
As the vehicle continues to ride up the median barrier or parapet, the vehicle is guided upwardly and rotated away from the barrier by the shape of the barrier or parapet. The upward and rotational movement of the vehicle converts some of the lateral energy of the vehicle into a vertical component which can be absorbed by the vehicle springs. The safety shape median barriers or parapets are also shaped to smoothly guide the vehicle from the median barrier or parapet back onto the roadway.The existing safety shape median barriers and parapets, while most frequently made of concrete, can also be made of extruded metal panels that are attached to vertically extending posts, and are particularly used on bridges or other elevated roadways. Most existing metal safety shape parapet or median barrier systems are installed by aligning pre-drilled holes in the panels with pre-drilled holes in the posts, and then passing a fastener through the aligned holes. Another drawback with existing median barrier and parapet systems is that the panels include access holes through which the fasteners are passed to enable assembly of the system.
These access holes are unsightly and can allow debris or wildlife to enter the barrier or parapet.During installing of existing highway safety shape median barriers or parapets, a foot piece is typically coupled to the deck.
The panels are then slid laterally into a slot in the foot pieces to couple the panel and the foot pieces together.
Because most prior art safety shape median barrier systems rely upon the alignment of pre-drilled holes, as more panels are mounted it becomes increasingly difficult to mount the panels to the posts due to the accumulated out-of-range tolerances.
A new post is then mounted adjacent to the existing post, and a new section of panels are restarted to reset the out-of-tolerance measurements.
However, the discontinuities formed by this method of construction may create areas of weakness at the discontinuities.
Furthermore, the discontinuities create a series of discreet, structurally independent sections within the median barrier or parapet system. Each section has little ability to transfer impact loads to its adjacent sections, and therefore each section of the median barrier or parapet system stands alone when receiving an applied force.In order to address this problem, metal plates may be bolted to the median barrier or parapet and located such that the plates extend over a discontinuity. Alternately or additionally, the median barrier or parapet may include an upper section of railing that bridges the discontinuity. While providing some segment-to-segment continuity, these measures do not significantly address the loss of continuity in such median barrier or parapet sections.Accordingly, there is a need for a safety shape median barrier or parapet system that is easy to install, and provides flexibility during installation by accommodating variations in the dimensions and locations of various system components. There is also a need for a safety shape median barrier or parapet system that provides ready access to the bolts that attach the system to the deck, and that reduces the effect of vertical discontinuities in the system.SUMMARY OF THE INVENTIONThe present invention is a safety shape median barrier and a parapet system that is easy to install, accommodates size variations in various components, provides ready access to the mounting bolts during installation, and reduces the effect of vertical discontinuities in the system.
More particularly, the present invention utilizes a plurality of panels, each panel including one or more channels shaped to receive a clamp bar therein. The clamp bars can be slid within the channels and mounted to a post or other structure by a fastener.
Because the clamp bar is free to slide within the panels, the panels need not have pre-drilled holes.
Because there is no buildup of out-of-range tolerances in the median barrier or parapet of the present invention, the median barrier or parapet can be installed as a substantially continuous system.The various components of the present invention can be arranged such that discontinuities in a layer of components of the system are spanned by the structure of an adjacent component. In this manner, the system can be assembled so that there are no discontinuities that extend throughout the height of the median barrier or parapet system, which increases the strength of the median barrier or parapet.In one embodiment, the present invention includes a plurality of base plates that are coupled to the bottom of the posts, and the base plates are shaped to receive the bottom of the lower panels. Because each base plate has a fixed distance between its outer edges and the post, the base plates precisely set the lateral spacing of the lower panels. In this matter, the tolerances in the system and the loading bearing characteristics of the system can be tightly controlled. The base plates also help to transmit applied loads into tensile and compressive forces to improve the load bearing characteristic of the median barrier or parapet system.In another embodiment, the present invention also includes a support element that receives a panel therein to couple the panel to the deck. The support element is attached to the deck by one or more bolts, and includes an inwardly opening end surface that receives a lower flange of the panel therein. The support element enables the panel to rotate out of the vertical plane of the mounting bolt and thereby provides access for tightening of the bolt.In one embodiment, the invention is a parapet for mounting on a deck and resisting applied loads comprising a base plate located on the deck and a post coupled to the base plate and extending generally upwardly from the deck. The parapet further includes a lower panel pivotably coupled to the base plate and the lower panel form a triangular truss for resisting applied loads.Accordingly, it is an object of the present invention to provide a median barrier or parapet that is easy to install, robust, can accommodate variations in size of its various components, and reduces the effects of any discontinuities.
Other objects and advantages of the present invention will be apparent from the following description and the accompanying drawings.BRIEF DESCRIPTION OF THE DRAWINGSFIG.

Although the term “deck” is used throughout this application, it should be understood that the term deck means any surface upon which the median barrier or parapet of the present invention can be mounted, including roadways, bridges, concrete structures, earth, etc.
A plurality of mounting bolts 14 extend upwardly from the deck 12, and the median barrier 10 is coupled to the mounting bolts 14 to couple the median barrier to the deck 12. The median barrier 10 is preferably made of metal, such as aluminum, and includes a plurality of posts 16 that extend down to the road surface, and a plurality of upper panels 20 and lower panels 22 are coupled to either side of the post 16 to form the mediam barrier 10.
A plurality of intermediate bases 24 are located between each post 16, and a plurality of upper panels 20 and lower panels 22 are coupled to either side of the intermediate bases and posts.
3, each lower panel 22 includes a lower flange 23 that includes a generally outwardly extending lip 25. 4, the lower panels 22 include a groove 98 that receives a tab 100 of the upper panel 20 therein such that the upper 20 and lower 22 panels are interfit together.
The lower panel 22 also includes a tab 104 that is received in a groove 106 in the upper panel 20.As best shown in FIG. Each post 16 is a generally vertically extending I-beam, channel, or other similar structure and in the illustrated embodiment the post 16 has a central web 30 and two end flanges 32, 34. Similarly, the end flanges 32, 34 each include a pair of upper holes 36 and a pair of lower holes 38. For each set of holes 36, 38, one hole is located on one side of the central web 30 and the other hole is located on the other side of the central web.The base plate 26 includes a pair of upwardly-extending projections 40, a center portion 42 located between the two projections 40, and a pair of generally upwardly-extending ridges 44 at each outer end of the base plate. 7B, each base plate 26 includes a set of elongated slots 48, each slot 48 being shaped to receive a mounting bolt 14 therethrough. As will be discussed in greater detail below, the elliptical or oval shape of the holes 48 provides tolerance for any misalignment of the posts 16.As shown in FIG.
6B, each of the first and second support elements 52, 54 similarly includes a set of elongated slots 62 therein, and the support elements 52, 54 can be attached to the deck 12 by passing a mounting bolt 14 through each slot 62 in the same manner as the base plates 26 (see FIG. Each support element 52, 54 may also include more than one slot 62, such as the embodiment in FIG. Each intermediate base 24 includes a backing post 66 located above each corresponding support element 52, 54.
Each backing post 66 is an I-beam similar to the post 16, and includes a central web 68, a pair of end flanges 70, 72 and a pair of upper 69 and lower 76 holes formed in each of the end flanges 70, 72 (FIG.
The backing post 66 is similar to a post 16, but does not extend down to the deck 12.As shown in FIG.


2, three intermediate bases 24 are located between each post 16; in the embodiment shown in FIG. 2 and 5, each intermediate base 24 includes a first support element 52 and second support element 54, and each intermediate base 24 therefore lacks the center portion 42 of the base plates 26.
Each support element 52, 54 includes a projection 56 at its inner edge that corresponds to the projection 40 on base plate 26. Each support element 52, 54 includes a ridge 58 at its outer edge, each ridge 58 having a notch 60 formed therein and goes to the ridges 44 of the base plate 26.As best shown in FIG. 2, the median barrier 10 includes a plurality of toe clips 70 located on top of the base plate 26 and each support element 52, 54. Each toe clip 28 is located between a projection 40 and a ridge 44 on a base plate 26 which serves to locate the toe clips 70 on the base plate 26. Similarly, on each support element 52, 54, each toe clip 70 is located between a projection 56 and ridge 58 . In order to couple a toe clip 70 to the median barrier 10, the toe clip 70 is located over a base plate 26 or support element 52, 54 such that the mounting bolts 14 extending through the base plate or support element 52, 54 are received through the opening 71 of the toe clip 70. The mounting bolts 14 and fastener 72 also couple the base plates 26 and support elements 52, 54 to the deck 12.As best shown in FIGS. Thus, each toe clip 70 and its associated ridge 44, 58 define an opening 75 therebetween (See FIG. Because each toe clip 70 receives a lower panel 22 against its open end 74, the projections 40, 56 (via the toe clips 70) also help to determine the location of the lower panels 22 (that is, the left-to-right location of the lower panels 22 in FIG. As will be discussed in greater detail below, the intermediate bases 24 and support elements 52, 54 also restrain the lower panels 22 from lateral movement during impact forces applied by vehicles or other means. The intermediate bases 24 also provide points for the panels 20, 22 to absorb tensile loads, which enables the median barrier to resist rotational forces upon impact of a vehicle.As shown in FIG.
3, the lip 25 of the lower flange 23 of each lower panel 22 is captured between the open end 74 of each toe clip 70 and the ridge 44 of the associated base plate 26. The lip 25 of each lower panel 22 is also received in a notch 46 of any associated base plates 26. Because the distance between the ridges 44 is fixed by the base plate 26, the base plate 26 sets the lateral spacing of the lower ends of opposed lower panels 22. 2 and 5, each support element 52, 54 is bolted to the deck 12 at each intermediate base 24.
Accordingly, the lateral spacing between the lower edges of each opposed lower panel 22 is also controlled at each intermediate base 24 location.As best shown in FIG. 5, the upper panels 20 and lower panels 22 may be made from an extruded, webbed material, such as aluminum. Each upper panel 20 includes a channel 80 extending through the length of the panel 20, and each lower panel 22 similarly includes a channel 82 extending through the length of the panel.
Each channel 80, 82 includes a narrowed throat portion 84, and is shaped to slidingly receive one or more clamp bars 86 therein.
Each clamp bar 86 is shaped to fit within a channel 80, 82 such that the clamp bar 86 can be passed into a channel 80, 82 at the end of each panel 20, 22, but the clamp bar 86 cannot be pulled through a throat 84 of the channel 80, 82.As shown in FIGS.
9-10, each clamp bar 86 is generally “mushroom shaped” in end view and includes a head portion 88 and a neck portion or shank 89. Each clamp bar 86 includes a pair of threaded holes 92 that can be aligned with a corresponding set of upper 36 and lower 38 holes located in a post 16 (FIG. A fastener or fasteners 90 can then be passed through the holes 69, 76, or 36, 38 with which the clamp bar is aligned. The fasteners 90 are received in the holes 92 of the clamp bar 86 to couple the associated upper or lower panel 20, 22 to the backing post 66 or post 16.
Because the clamp bars 86 are received in the channels 80, 82 of the upper 20 and lower 22 panels, the upper and lower panels 20, 22 are thereby coupled to the posts 16, and the vertical motion of the panels 20, 22 relative to the posts 16 is restrained. As will be discussed in greater detail below, this method of attaching the upper and lower panels 20, 22 to the posts 16 and backing posts 66 provides the installer great flexibility due to the ability of the clamp bars 86 to slide laterally within the channels 80, 82.The median barrier 10 preferably includes a top cap 108 located on top of the upper panel 20. 5, the top cap 108 includes a pair of downwardly-extending flanges 110 received in a corresponding notch 112 in each upper panel 20.
The top cap 108 also includes a pair of horizontally-extending ledges 116 that are received on the top edge 118 of the upper panels 20.
In order to couple the top cap 108 to the upper panel 20, the top cap 108 is loosely placed on the upper panel 20 such that the flanges 110 are received in the notches 112 and the ledges 116 rest on to the top edges 118 of the upper panels 20. Next, and a pair of side rails 126 are coupled to the upper panels 20 and top cap 108 to complete the assembly.
The upper flange 130 is received in a groove 120 of the top cap 108, and the lower flange 132 is received in a groove 136 in an upper panel 20.A plurality of fasteners 138 are then passed through an opening 139 in the side rails 126 and received into a slot 140 in the associated upper panel 20 to secure the side rails 126 to the panels 20.
The longitudinally extending slot 140 preferably has a running thread into which the fasteners 138 may be screwed. For example, the top cap 108 may include structure for receiving flashers, signs, or lights.A preferred method for installing one embodiment of the median barrier 10 will be described in detail below.
However, it is to be understood that the described and illustrated method of installation is only one method that may be used to install the median barrier 10, and other methods and steps of installation may be utilized without departing from the scope of the invention.
In particular, several of the steps described herein may be carried out in different sequence than that described herein, or in different manners, in order to achieve the same result.FIGS.
11-18 are a series of front views illustrating one manner for assembling the median barrier 10, and FIGS.
11, a series of mounting bolts 14 are first sunk into the deck 12, and the mounting bolts 14 are preferably coupled to or sunk into the deck 12 during the pouring or formation of the deck.
The mounting bolts 14 are spaced longitudinally along the length of the deck 12, and generally define the location about which the median barrier 10 will be mounted.
A plurality of support elements 52, 54 are then located on the deck 12 between each post 16, as shown in FIG.
The support elements 52, 54 are coupled to the deck 12 by lowering each support element 52, 54 onto the deck such that a bolt 14 is received through each elongated slot 62 of the support elements 52, 54 (See FIGS.
11 illustrates two sets of support elements 52, 54 located between each post 16, although this number may be varied, as desired. Once the posts 16, base plates 26 and support elements 52, 54 are located on the deck 12, they should form a generally straight line upon which the panels 20, 22 will be located, although the system can accommodate some curvature in the median barrier 10.Next, as shown in FIGS. 12 and 20, a lower panel 22 is placed on a number of base plates 26 (four base plates 26 in the illustrated embodiment) and on the corresponding support elements 52 located between the base plates 26. The lower panel 22 is placed over the base plates 26 and support elements 52 such that the lower flange 23 of the lower panel 22 is received in the notches 46 of the base plate 26 and the notches 60 of the support elements 52. A number of wooden blocks 160 may be located on the deck 12 below the lower panel 22 to help support the weight of the lower panel 22 and maintain the panel 22 leaned against the posts 16.
Next, a toe clip 70 is located over each of the mounting bolts 14 that extend through the base plates 26 and support elements 52 that are receiving and supporting the lower panel 22.As shown in FIG. 3, each toe clip 70 is mounted on a base plate 26 or support element 52 such that its open end 74 receives the lower flange 23 of the lower panel 22 therein.
Alternately, in order to save time, the toe clips 70 may be mounted on only a few of the mounting bolts 14 extending through the base plates 26 and support elements 52 supporting the lower panel 22 to temporarily hold the lower panel 22 in place. Of course, in this case, the installer must return to later mount toe clips 70 over the remaining mounting bolts 14 before assembly is completed.A nut 72 and washer 73 (FIGS. 4-5) are then loosely threaded onto each mounting bolt 14 protruding through a toe clip 70. The nuts 72 are not yet tightened down to allow for subsequent adjustments in the position of the base plates 26 and support elements 52 as the median barrier 10 is assembled.
In particular, the elongated slots 48, 62 in the base plates 26 and support elements 52 allow the base plates 26 and support elements 52 to shift in the direction of the slots 48, 62. After the median barrier system is constructed and the pieces of the median barrier system, including the panels 20, 22, are fit together, the panels 20, 22 form a least-fit distance curve along the outer face of the panels. Thus, upon initial placement on the deck 12, the base plates 26 and support elements 52, 54 are only loosely bolted into place. As the upper 20 and lower 22 panels are subsequently mounted to the posts 16, the base plates 26 and support elements 52, 54 will adjust their lateral position via the slots 48, 62 to accommodate the grade and curve of the deck.
The slots 48, 62 also provide compensation for bent panels as well as misaligned posts.Once the desired toe clips 70 are mounted into place, the lower panel 22 is essentially captured between the toe clips 70 and the ridges 44, 58 of the base plates 26 and support elements 52. The lower panel 22 can pivot about its lower flange 23, but the lower panel cannot be lifted vertically out of place. Once the lower panel 22 is captured by the toe clips 70, the only way to remove the lower panel is to longitudinally slide the lower panel out of the clips 70, or to remove the toe clips 70 to enable the lower panel 22 to be lifted vertically.The engagement of the lower panel 22 by the toe clips 70 and base plate 26 and support elements 52 enable the rotation of the lower panel 22.
3-5, each lower panel 22 includes a lower flange 23 that includes a generally outwardly extending lip 25. Each toe clip 70 includes an open end 74 that receives the lower flange 23 of the lower panel 22 therein, such that the lower flange 23 is captured between the open end 74 of the toe clip 70 and the ridge 44 on the base plate 26, or captured between the open end 74 of a toe clip 70 and a ridge 58 of a support element 52. The open end 74 of the toe clip 70 is generally curved, or concave, and contoured to match the profile of the outer surface of the lower flange 23. The lip 25 of the lower flange 23 is received in a notch 46 formed in the ridge 44 of the base plate 26 (FIG. 4), or received in a notch 60 of the ridge 58 of support element 52.The curved inner edge of the open end 74 of the toe clip 70 has a common center rotation with the curved outer surface of the flange 23 of the lower panel 22, and the common centers of rotation enables free rotation of the panel 22 within the toe clip 70 and base plate 26. 22, such that the upper panel 22? stably rests on the deck 12 or against the base plate 26.
When the panel 22 is in the open position, the lower panel 22 is supported by its heel 182 resting on the deck 12 or engaging the base plate 26.Once the lower panel 22 is properly located and all of the desired toe clips 70 are in place, the spacer blocks 160 are knocked out from under the lower panel and the nuts 72 on the mounting bolts may be tightened down. In order to access the nuts 72 on the mounting bolts 14, the lower panel 22 is preferably rotated to its open position, shown as panel 22? in FIG.
In this position, the lower panel 22? is rotated out of the vertical plane of the mounting bolts 14 which allows a worker to easily access the mounting bolts 14 and tighten the nuts 72 down. After the nuts 72 are tightened down, the lower panel 22 is preferably left in its open position for the time being.After the toe clips 70 are tightened down, a second lower panel 184 (FIG.
13) is then installed adjacent the first lower panel 22 in the downstream direction (the direction indicated by arrow A in FIG. 13) by lowering the panel 184 over a plurality of base plates 26 and support elements 52 located on the deck, in the same manner as panel 22 described above. The second lower panel 184 may be pivoted to its open position in the same manner described above for the first lower panel 22 to provide access to the bolts 14 for securing the nuts 72. A set of nuts 72 are then located on top of the mounting bolts 14 extending through the newly-located toe clips 70, and tightened down to fasten the second lower panel 184, and associated posts 16, toe clips 70, base plates 26 and support elements 52 to the deck 12. The second lower panel 184 is preferably left in its open position for the time being.After the two lower panels 22, 184 are secured, an upper panel 20 is secured to the posts 16 as shown in FIG. 14.In order to couple the upper panel 20 to the posts 16, the upper panel is located such that its channel 80 is located adjacent to the upper holes 36 of the flanges 32 of the posts 16. As will be clear for reasons discussed below, two clamp bars 86 are preferably located between each clamp bar 86 that will be coupled to a post 16 (these clamp bars will be used to couple the upper panel 20 to the backing posts 16). A set of fasteners 90 are then passed through the upper holes 36 in each of the four posts 16 spanned by the upper panel 20 and threadedly received in an associated clamp bar 86 received in the channel 80 of the upper panel 20 to attach the upper panel 70 to the posts 16. The upstream edge 188 of the upper panel 20 is preferably offset from the upstream edge 190 of the first lower panel 22 by, for example, one post 16. The offset helps to avoid concentrating any discontinuities in the median barrier 10 at a common vertical location, which improves the continuity of the system.
