Description

Technical Field

[0001] This utility model relates to the field of road and bridge guardrail technology, and in particular to a novel road and bridge guardrail structure. Background Technology

[0002] Road and bridge guardrails are safety facilities commonly found on roads, bridges, and construction sites. Their main functions include preventing vehicles or pedestrians from falling or colliding, protecting personal safety; guiding traffic flow and reducing accidents; and separating different functional areas to avoid confusion. They are commonly made of steel, such as round steel pipes, square steel pipes, or profiled steel sheets, and are an important branch of the building materials industry. As the industry continues to expand, the styles of guardrails are also constantly increasing.

[0003] Traditional road and bridge guardrails are generally installed by welding, which is not only time-consuming and labor-intensive, but also limited by site conditions. In some complex or dangerous construction environments, welding operations may be restricted, increasing the difficulty of construction. Furthermore, subsequent maintenance is difficult, as welded joints may be corroded or otherwise damaged, requiring re-welding or other treatments for repair.

[0004] Therefore, there is an urgent need to provide new types of road and bridge guardrail structures to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new type of road and bridge guardrail structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing a new type of road and bridge guardrail structure, including two fixed bases, and a support column is fixedly connected to the top of each of the two fixed bases;

[0007] Multiple sets of protective mechanisms are slidably installed between the two support columns;

[0008] Two sets of support mechanisms are symmetrically installed between each set of protective mechanisms, and fixing mechanisms are fixedly installed on both sides of the top of the support column.

[0009] Each of the aforementioned fixing mechanisms is secured to the support column by screws.

[0010] The present invention is further configured such that: the support column includes a vertical protective rod, and a convex sliding groove is provided at the center of both sides of the vertical protective rod.

[0011] Through the above technical solution, the fixed base and the support column are integrated into a single structure, which is sturdy and reliable, while the vertical guard rod provides protection in the vertical direction.

[0012] The present invention is further configured such that: the protective mechanism includes a horizontal protective rod, and convex sliders are fixedly connected to both sides of the horizontal protective rod, and a through circular hole is opened at the center of the top of each of the two convex sliders.

[0013] Through the above technical solution, the horizontal guard bar is responsible for providing protection in the horizontal direction.

[0014] The present invention is further configured such that: the convex sliders fixedly connected to both sides of the horizontal guard rod are respectively slidably installed in the convex grooves at the center of both sides of the vertical guard rod.

[0015] Through the above technical solution, the convex slider on the horizontal guard bar slides into the convex groove of the vertical guard bar, thereby achieving the positioning and support of the horizontal guard bar. The convex design of the convex slider ensures stable fit and reduces shaking.

[0016] The present invention is further configured such that: the support mechanism includes a support block slidably installed inside the convex groove, and the top and bottom of the support block are fixedly connected to limit posts.

[0017] The present invention is further configured such that: the support block is installed between two corresponding convex sliders, and the limiting post is respectively inserted into the corresponding round hole.

[0018] With the above technical solution, the support block is located between the two convex sliders to provide additional support, and the limiting post is inserted into the round hole to fix the horizontal guard bar, thereby ensuring that the horizontal guard bar remains stable in the working state.

[0019] The present invention is further configured such that: the fixing mechanism includes a fixing block inserted into the top of the convex groove, and the front end of the fixing block has a threaded hole corresponding to the screw.

[0020] With the above technical solution, the fixing block is fixed to the top of the convex groove, and at the same time, the fixing block restricts the position of the horizontal guard bar to prevent the horizontal guard bar from swaying up and down.

[0021] This utility model is further configured such that: the top of both sides of the front end of the vertical protective rod is provided with through holes corresponding to the screw and the threaded hole. Through the above technical solution, the through holes on both sides of the front end of the vertical protective rod are aligned with the screw and the threaded hole. The screw is inserted into the threaded hole through the through hole to fix the fixing block in the predetermined position, thereby preventing rainwater from entering the convex sliding groove and fixing the position of the convex sliding block.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. This utility model, by designing a convex groove and a slider, allows for the sliding installation of horizontal guardrails, reducing installation time and difficulty, simplifying the installation process, lowering the installation threshold, and making the installation of guardrails more convenient.

[0024] 2. By designing support blocks and fixing mechanisms, this utility model eliminates the need for welding when fixing horizontal guardrails, simplifying the fixing process and operation, and making installation, maintenance and inspection more convenient. Attached Figure Description

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Please see Figures 1-5 The new type of road and bridge guardrail structure includes two fixed bases 1, and each of the two fixed bases 1 is fixedly connected to a support column 2.

[0033] like Figures 1-3 As shown, the support column 2 includes a vertical guard rod 201. The vertical guard rod 201 has a convex groove 202 on both sides of the center. In actual operation, the fixed base 1 and the support column 2 are an integral structure, which is sturdy and reliable. At the same time, the vertical guard rod 201 is responsible for providing protection in the vertical direction.

[0034] like Figures 1-4As shown, multiple sets of protective mechanisms 3 are slidably installed between the two support columns 2. The protective mechanism 3 includes a horizontal protective rod 301. Convex sliders 302 are fixedly connected to both sides of the horizontal protective rod 301. A through circular hole 303 is opened at the center of the top of each of the two convex sliders 302. In actual operation, the horizontal protective rod 301 is responsible for providing protection in the horizontal direction.

[0035] like Figures 1-4 As shown, the convex sliders 302 fixedly connected to both sides of the horizontal guard rod 301 are slidably installed in the convex grooves 202 at the center of both sides of the vertical guard rod 201. In actual operation, the convex sliders 302 on the horizontal guard rod 301 slide into the convex grooves 202 of the vertical guard rod 201 to achieve the positioning and support of the horizontal guard rod 301. The convex design of the convex sliders 302 ensures stable fit and reduces shaking.

[0036] like Figures 3-5 As shown, two sets of support mechanisms 4 are symmetrically installed between each set of protective mechanisms 3. The support mechanism 4 includes a support block 401 that is slidably installed inside the convex groove 202. The top and bottom of the support block 401 are fixedly connected to limit posts 402.

[0037] like Figures 3-5 As shown, the support block 401 is installed between the two corresponding convex sliders 302, and the limiting post 402 is inserted into the corresponding round hole 303. In actual operation, the support block 401 is located between the two convex sliders 302 to provide additional support, and the limiting post 402 is inserted into the round hole 303 to fix the transverse guard bar 301, thereby ensuring that the transverse guard bar 301 remains stable in the working state.

[0038] like Figures 1-3 As shown, fixing mechanisms 5 are fixedly installed on both sides of the top of the support column 2. The fixing mechanism 5 includes a fixing block 501 that is inserted into the top of the convex slide groove 202. The front end of the fixing block 501 is provided with a threaded hole 502 corresponding to the screw 6. In actual operation, the fixing block 501 is fixed to the top of the convex slide groove 202. At the same time, the fixing block 501 restricts the position of the horizontal guard bar 301 to prevent the horizontal guard bar 301 from shaking up and down.

[0039] like Figures 1-3 As shown, each fixing mechanism 5 is fixed to the support column 2 by screws 6.

[0040] like Figures 1-3As shown, the top of both sides of the front end of the vertical guard rod 201 is provided with through holes corresponding to the screw 6 and the threaded hole 502. In actual operation, the through holes on both sides of the front end of the vertical guard rod 201 are aligned with the screw 6 and the threaded hole 502. The screw 6 is inserted into the threaded hole 502 through the through hole to fix the fixing block 501 in the predetermined position, thereby preventing rainwater from entering the convex slide groove 202 and fixing the position of the convex slider 302.

[0041] In use, the two fixed bases 1 are first fixed on the road bridge with a certain distance between them. Then, the convex slider 302 on the horizontal guardrail 301 is slid into the convex groove 202 of the vertical guardrail 201. At this time, the support block 401 is slid into the convex groove 202 and the limiting post 402 is inserted into the round hole 303. This operation is repeated until the horizontal guardrail 301 reaches a suitable height. At this time, the fixing block 501 is slid into the top of the convex groove 202. At the same time, the screw 6 is aligned with the through holes and threaded holes 502 on both sides of the front end of the vertical guardrail 201 and the screw 6 is inserted to fix the fixing block 501 in the predetermined position. At this time, the position of the convex slider 302 is fixed.

[0042] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
