Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a prefabricated bridge guardrail which is easy to disassemble. Background Art

[0002] During bridge construction, it is usually necessary to install guardrails around the construction site to play a certain isolation role. Generally, guardrails are installed by welding or connecting multiple connecting parts of different sizes. However, when there are a large number of guardrails to be installed, welding or using a large number of connecting parts will cause installation problems.

[0003] In the prior art, the Chinese utility model with publication number: CN215758520U discloses a prefabricated reinforced concrete anti-collision guardrail for a bridge that is easy to install, including a base, the base is a quadrangular pyramid structure, the top of the base is provided with two rectangular grooves, a fixing rod is fixedly installed inside the rectangular groove on the base, two connecting rods are movably installed between the two fixing rods, and a guardrail body is fixedly installed between the two connecting rods, the insertion rod is pressed into the installation groove, the positioning block is retracted into the elastic frame, the insertion rod is pressed until the bottom block of the insertion rod is inserted into the insertion hole, and the positioning block pops out in the direction of the limiting hole under the elastic force of the spring to be inserted into the limiting hole. When the guardrail body needs to be disassembled, the positioning block is pressed in the limiting hole, the positioning block is retracted into the elastic frame here, and the insertion rod is pulled out of the installation groove to disassemble the guardrail body, thereby facilitating the disassembly and assembly of the guardrail body;

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a prefabricated bridge guardrail that is easy to disassemble, including a support assembly 100, two groups of limit assemblies 300 are symmetrically installed on the support assembly 100, and a connection assembly 200 is clamped on the support assembly 100 through the two groups of limit assemblies 300, and a protection assembly 400 is installed on the connection assembly 200;

[0024] The connection assembly 200 includes two groups of prefabricated columns 201 arranged symmetrically. On the opposite sides of the two groups of prefabricated columns 201, fitting grooves 202 are opened. On one side of the prefabricated column 201 opposite to the fitting groove 202, two groups of first connection protrusions 205 are fixedly connected. On the opposite side of the other group of prefabricated columns 201 relative to the fitting groove 202, two groups of second connection protrusions 207 are fixedly connected. On the lower surfaces of the two groups of second connection protrusions 207, positioning pins 208 are fixedly connected. On the upper surfaces of the two groups of first connection protrusions 205, insertion holes 206 for the positioning pins 208 to rotate and insert are opened. The two groups of first connection protrusions 205 and the two groups of second connection protrusions 207 are arranged in a staggered and alternating manner.

[0025] On the lower ends of the opposite sides of the two groups of prefabricated columns 201, positioning holes 209 are opened. On one side of the fitting groove 202, two groups of bottom grooves 203 are symmetrically opened. On the bottoms of the two groups of bottom grooves 203, clamping grooves 204 are opened. By inserting the positioning blocks 301 of the limit assembly 300 into the positioning holes 209, the prefabricated column 201 can be locked, improving the stability of the prefabricated column 201 installed on the counterweight base 101.

[0026] The protection assembly 400 includes two groups of support angle plates 401. On the opposite sides of the two groups of support angle plates 401, a plurality of protection cross beams 405 are fixedly connected. On the adjacent sides of the two groups of support angle plates 401 and the plurality of protection cross beams 405, fitting plates 402 are integrally formed. On one side of the fitting plate 402, an installation block 403 that is clamped in the clamping groove 204 is fixedly connected. Through the installation block 403, the whole protection assembly 400 can be conveniently lapped on the prefabricated column 201, improving the disassembly and assembly efficiency of the protection assembly 400.

[0027] The cross-section of the installation block 403 is the same as that of the clamping groove 204. The cross-section of the installation block 403 is convex-shaped. The bottom groove 203 is a rectangular groove. On one side of the fitting plate 402, a through hole 404 is opened. Through the convex-shaped structure setting, the installation block 403 can be quickly embedded in the bottom groove 203 and embedded in the clamping groove 204 under the action of gravity, improving the installation efficiency and installation stability. The through hole 404 is convenient for inserting a steel pipe to lift the protection assembly 400 for easy disassembly.

[0028] On one side of multiple groups of protective crossbeams 405, multiple groups of protective vertical beams 406 are fixedly connected. The multiple groups of protective vertical beams 406 are arranged perpendicular to the multiple groups of protective crossbeams 405 in a staggered manner.

Through the multiple groups of protective crossbeams 405 and the multiple groups of protective vertical beams 406, the protective effect is improved, preventing pedestrians from passing through the gaps. At the same time, reflective strips are pasted in the warning reflective grooves 407, which can play a warning role and prevent vehicles from colliding at night.

[0029] The support assembly 100 includes a counterweight base 101. On the upper surface of the counterweight base 101, installation grooves 102 for inserting two groups of precast columns 201 are symmetrically provided. On both sides of the counterweight base 101, two groups of stable ladder blocks 104 are fixedly connected. On the opposite side of the two installation grooves 102, right-angle grooves 103 are provided. The support stability of the counterweight base 101 is improved through the stable ladder blocks 104, thereby improving the stability of the entire guardrail.

[0030] The limit assembly 300 includes a positioning block 301 slidably connected in the right-angle groove 103. On the upper surface of the positioning block 301, a groove dial block 302 is fixedly connected. On one side of the positioning block 301, an extension hole 303 is provided. At the bottom of the extension hole 303, a telescopic rod 304 is fixedly connected. A spring 305 is sleeved on the outer side of the telescopic rod 304. The position of the positioning block 301 can be adjusted conveniently through the groove dial block 302. When the positioning block 301 compresses the spring 305, it is convenient for the installation and disassembly of the precast column 201. When the elastic potential energy of the spring 305 decreases, the positioning block 301 inserts into the positioning hole 209, facilitating the positioning of the precast column 201 and improving the connection stability between the counterweight base 101 and the precast column 201.

[0031] During use, place the support assembly 100 at a suitable position on the bridge. First, push the groove dial block 302 successively to compress the spring 305 by the positioning block 301, thereby installing the precast column 201 in the installation hole, and then release the groove dial block 302 to make the positioning block 301 inserted into the positioning hole 209 to limit the precast column 201. Adjust the position and angle of the counterweight base 101 according to the range to be protected on the bridge. Adjacent guardrails are spliced by inserting the positioning pins 208 of the connection assembly 200 into the jacks 206, which is simple to operate. Finally, insert a steel pipe through the through-hole 404 to lift the protection assembly 400, so that the fitting plate 402 fits with the fitting groove 202, and then the installation block 403 is embedded in the bottom groove 203. Under the action of gravity, the installation block 403 is inserted into the card slot 204 to complete the overall installation of the guardrail, improving the installation efficiency. Reverse operation can disassemble the guardrail, improving the overall disassembly and assembly efficiency of the guardrail and the protection effect.
