Bridge railing assembly for flooding preparation {BRIDGE RAILING ASSEMBLY FOR PROVIDING AGAINST INUNDATION}

The present invention relates to a bridge railing assembly, and more particularly, to a bridge railing assembly for flooding prepared to prevent damage and contamination of railings due to flooding of the bridge while installed on the bridge.

Typically, a railing for a bridge is installed on a bridge in the form of a fixed structure or assembly, and a guard installed across the support between a plurality of struts arranged in two rows, left and right on the bridge, and a pair of neighboring struts. Consists of rails. At this time, the guardrail of the handrail serves to prevent the driver of the vehicle, such as a pedestrian or a bicycle, from falling out of the bridge.

On the other hand, when the bridge is submerged, for example, floating matters such as tree branches, house damages, car damages, or various household appliances are often floated from the upper stream to the lower stream. For example, railings were often heavily contaminated or damaged.

In other words, if a float is suspended in the guardrail, the strong water pressure of the stream is transmitted directly to the guardrail of the rail via the float, which greatly damages the railing, and even after the flow rate of the stream decreases, contaminants from the railing, especially the guardrail, are removed. It takes a lot of labor and money to remove it.

Therefore, the present invention is devised to solve the problems of the prior art, the guardrail performs its original function for the safety of pedestrians or vehicles (especially bicycles) riders, as well as to open the float by itself when flooded It is an object of the present invention to provide a bridge railing assembly for submersion that is designed to prevent the jamming.

As shown, the bridge railing assembly 1 of the present embodiment includes a fixed column 2, a variable column 3 and a plurality of guard rails 4 installed laterally between them. The term "variable column" is called by the inventor according to the characteristics that the overall height is variable.

In the present embodiment, the guard rails 4 are arranged horizontally with three guard rails 2 and one variable column 3 adjacent to each other. The number of is not limited to the present invention.

In addition, the variable support (3) is located between two neighboring fixed support (2), the position of the variable support (3) or the arrangement of the variable support (3) and the fixed support (2), As will be explained in detail later, it is possible to open more guard rails 4 upon bridge flooding.

The guard rail 4 of the present embodiment is provided with stone pieces 4a and 4b at both ends, and one end of the stone piece 4a is connected to the hinge shaft portion 21 of the fixing column 2 by the guard rails 4 by hinges. An area is provided and upper and lower through holes 42 are formed in the other end piece 4b.

The holding column 2 has a hinge shaft portion 21 at a portion connected to the guard rail 4 while standing on the bridge b to enable the guard rail 4 to be rotated left and right. .

The variable support 3 of this embodiment has a structure for supporting both ends of the guard rail 4 together with the fixed support 2 described above, while the separation and connection with the guard rail 4 is submerged as described in detail below. It is to be made selectively according to the, so that when the immersion, the guard rail (4) can be rotated about the hinge shaft portion 21 of the fixed column (2) while being separated from the variable column (3) to open itself Do it.

The variable support 3 is capable of lifting up and down along the support rod 32 and the support rod 32 fixedly placed on the bridge b so that the guard rail 4 can open by itself when the bridge is flooded. It includes a lifting bar 34 to be installed.

In the present embodiment, the holding rod 32 has a hollow 322 to allow the lifting rod 34 to move up and down, and the lifting rod 34 of the upper opening type can protrude upward. Form a structure.

In addition, the holding rod 32 is provided with a water inlet 323 at the lower end of the outer wall to allow the inflow of water into the hollow 322 at the time of submersion, when the bridge is submerged, by the water pressure of the water or buoyancy by water Allow rod 34 to be raised. In this case, when the lifting rod 34 is made of a material having a specific gravity smaller than that of the water, the lifting rod 34 may be more easily lifted by hydraulic pressure or raised only by buoyancy by water.

In addition, the holding rod 32 has a plurality of slit-shaped guides 324 provided on both sides of the outer wall to correspond to the number of guard rails, and the slit-shaped guide 324 is described below. 34 to perform the function of guiding the step 342 up and down.

As mentioned above, the lifting bar 34 is configured to protrude past the upper end of the support rod 32 while being removably fitted in the hollow 322 of the support rod 32, the support on the outer periphery Protruding through the slit-shaped guide 324 of the rod 32, respectively, is provided with a step piece 342 integrally fitted into the step hole 42 of the guard rail 4 mentioned above.

In the present embodiment, the walking piece 342 extends downward from the top to penetrate the walking hole 42 from the top to the bottom, which is integrated with the lifting bar 34 by the inundation of the bridge. When the in-step piece 342 rises, the step of the step piece 342 and the step hole 42 are mutually released so that the guard rail 4 having the step piece 342 integrally opens on its own.

In addition, the holding rod 32 has a structure in which a bracket 326 having a pair of shaft holes 326a are integrally installed on both sides of the outer wall, and the bracket 326 is in a position where the guard rail 4 is closed. While supporting the guard rail 4 up and down more firmly, its shaft hole 326a coincides in the closed position of the guard rail 4 with the step hole 42 of the guard rail 4, and the lifting bar 34 ) Allows the step piece 342 to pass through the shaft hole 326a and the step hole 42 at the same time.

As described above, in the bridge railing assembly 1 of the present invention, the guard rail 4 is normally supported by both the fixed column 2 and the variable column 3 while the bridge rail assembly 1 is normally used. The lifting bar 34 of (3) rises along the support bar 32 by the force of water (hydraulic pressure or buoyancy), and the step piece 342 of the lifting bar 34 and the step hole of the guard rail 4 ( The release of the step 42 allows one end of the guard rail 4 to be separated from the variable column 3, which causes the guard rail 4 to rotate about the hinged fixed column 2 and open itself. .

At this time, it is most preferable that one variable column 3 is located between two neighboring fixed column 3, which is separated from two sets of guard rails adjacent to each other from one variable column 3, This is because the two sets of guard rails 4 can be opened separately from one variable column 3 at the same time.

5 is a cross-sectional view illustrating the variable support 3 of the bridge railing assembly 1 according to an embodiment of the present invention.

As shown in FIG. 5, the variable support 1 according to the present embodiment has a specific gravity higher than that of the buoyancy drive member 34a of Styrofoam material and water, for example, where the lifting rod 34 has a smaller specific gravity than water. It can be seen that it is composed of a driven lifting member 34b of a metal material.

The buoyancy drive member 34a and the driven lifting member 34b form a structure arranged up and down in the hollow of the holding rod 32. Therefore, when the buoyancy drive member 34a rises by buoyancy by water, the driven lifting member 34b above is lifted by the lifting force.

At this time, the driven elevating member 34b is integrally provided with a step piece 342 which is stepped into the step hole 42 of the guard rail 4 (see FIGS. 1 to 4), and the step piece 342 also has a high strength. Because it is made of metal, there is no fear of damage even after long use.

As described above, the elevating bar 34 composed of the buoyancy driving member 34a and the driven elevating member 34b has a higher elevating bar due to the strength of the step piece 342 and water compared to the integrated elevating bar 34 of the previous embodiment ( It may be more useful in that it satisfies all of the reliable rises in 34).

As described above, the bridge railing assembly of the present invention performs an inherent function of protecting pedestrians or riders (riders such as bicycles or other vehicles) and guards when flooding bridges due to natural disasters such as typhoons and floods. The rails are self-opening to prevent various floats from hanging on the guard rails, thereby greatly preventing contamination and damage of the guard rails.

In addition, the bridge railing assembly of the present invention has a structure in which the elevating rod rising by buoyancy is located in the inner hollow of the holding rod while the elevating rod and the guard rail are separated by the elevating by the buoyancy of the elevating rod. As the elevating rod is located in the hollow inside the holding rod, the guard rail is fixed in a rigid state in normal times, and the guard rail can be opened more stably and reliably during flooding.

Furthermore, the bridge rail assembly of the present invention has a structure in which two sets of left and right guard rails can be opened simultaneously by the action of one variable column, thereby reducing the cost of assembly and installation and opening the guard rail more reliable. Makes it possible.
