Description

Technical Field

[0001] This utility model relates to the field of corrugated guardrails, and in particular to a beam support structure based on old road corrugated steel guardrails. Background Technology

[0002] Corrugated beam steel guardrails are widely used in highway safety protection. They form a continuous barrier by connecting the beams and posts, and use the deformation of the soil base, posts and beams to absorb collision energy, forcing out-of-control vehicles to change direction.

[0003] Existing guardrails mostly use ordinary bolts to fix corrugated beams to the posts, which has the following shortcomings. First, after long-term use, the joints of old road guardrails may rust, loosen or deform, resulting in a decrease in overall strength. Second, the traditional connection method makes it easy for the beams to detach from the posts when subjected to impact, causing the protection to fail, which is not practical. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a beam support structure based on old road corrugated steel guardrails. It aims to improve the existing technology where, after long-term use, the posts and connectors of old road guardrails may rust, loosen, or deform, leading to a decrease in overall strength. Secondly, in the traditional connection method, the beam is prone to detach from the post when subjected to impact, causing the protection to fail.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a crossbeam support structure based on old road corrugated steel guardrail, comprising two corrugated crossbeams, a support mechanism jointly installed on the rear side of the two corrugated crossbeams, a vertical pole installed at the rear of the support mechanism, the support mechanism comprising a support member, eight reinforcing ribs fixedly connected to the rear side of the support member, the eight reinforcing ribs being divided into upper and lower groups of four, a front clamp provided on the rear side of each group of reinforcing ribs, a rear clamp provided on the rear side of the front clamp, two anti-detachment locking rods provided in a sleeve between the front clamp and the rear clamp, a gasket fixedly connected to the front side of the support member, the upper and lower parts of the support member being folded away from the vertical pole to form a buckle, and the corrugated crossbeam being movably connected to the buckle.

[0006] As a further description of the above technical solution: The front clamp is fixedly connected to a locking block on both the left and right sides.

[0007] As a further description of the above technical solution: The upper and lower parts of the left and right sides of the rear clamp are fixedly connected with the No. 2 locking block, and the gap between the two No. 2 locking blocks is adapted to the No. 1 locking block.

[0008] As a further description of the above technical solution: The anti-disengagement locking rod is connected to and movably connected to the first locking block and the second locking block, and the upper and lower parts of the anti-disengagement locking rod are threaded with locking caps.

[0009] As a further description of the above technical solution: Two shear sleeves are movably connected through the middle of the upright, and each of the two shear sleeves is movably connected to a screw rod in the middle. The screw rod is movably connected through the corrugated beam, the buckle, and the support member.

[0010] As a further description of the above technical solution: The outer wall of the upright is fixedly connected with multiple limit rings, and the front clamp and the rear clamp are in contact with the limit rings.

[0011] This utility model has the following beneficial effects: 1. In this utility model, the combined design of support components, multiple sets of reinforcing ribs and buckle edges greatly improves the connection strength between the corrugated beam and the upright. At the same time, the mutual cooperation between components such as shims and shear sleeves can reduce the problems of corrosion and slight deformation at the connection, reduce the overall strength reduction caused by the wear and tear of basic components, and extend the service life and protective performance of old road guardrails.

[0012] 2. In this utility model, by setting a locking cooperation between the No. 1 locking block, the No. 2 locking block and the anti-detachment locking rod, and the shear sleeve to limit the penetration of the crossbeam and the support structure, multiple anti-detachment protections are formed, which effectively solves the problem that the crossbeam is easy to detach from the column when impacted in traditional bolted connections, and avoids the failure of protection. At the same time, the modular clamp and locking structure are easy to install and maintain, and the practicality is significantly enhanced. Attached Figure Description

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

[0016] Reference Figures 1-3 This utility model provides an embodiment of a beam support structure for a corrugated steel guardrail on an old road. It includes two corrugated beams 1, the number of which can be increased according to the actual guardrail length. A support mechanism 2 is installed on the rear side of both corrugated beams 1 to facilitate connection and support between them. A vertical post 3 is installed at the rear of the support mechanism 2, embedded in the soil, for further support. The support mechanism 2 includes a support member 21, the shape of which is adapted to the corrugated beam 1. Holes for bolt installation and fixing are provided on the corrugated beam 1, the support member 21, and the gasket 212. Eight reinforcing ribs 22 are fixedly connected to the rear side of the support member 21 to improve its stability and strength. The eight reinforcing ribs 22 are arranged in two groups of four, upper and lower. Each of the reinforcing ribs 22 has a front clamp 23 on its rear side, and a rear clamp 24 on its rear side. The front clamp 23 and the rear clamp 24 can form a complete clamp, allowing the support member 21 to be fixed to the upright 3. Two anti-disengagement locking rods 25 are provided between the front clamp 23 and the rear clamp 24 to lock and fix the front clamp 23 and the rear clamp 24. A gasket 212, which can be made of rubber or other materials, is fixedly connected to the front side of the support member 21 to fill the micro gap between the support member 21 and the corrugated beam 1, to buffer vibration, and to prevent corrosion caused by friction between metal parts. The upper and lower parts of the support member 21 are folded away from the upright 3 to form a retaining edge 211, which can cover the upper and lower edges of the corrugated beam 1. The corrugated beam 1 is movably connected to the retaining edge 211.

[0017] like Figure 4As shown, locking blocks 231 are fixedly connected to the left and right sides of the front clamp 23, and locking blocks 241 are fixedly connected to the upper and lower parts of the left and right sides of the rear clamp 24. The gap between the two locking blocks 241 is adapted to the locking block 231, so that the front clamp 23 and the rear clamp 24 can be spliced ​​together. The anti-loosening locking rod 25 is connected to the locking blocks 231 and 241 through and movably, and is used to fix the front clamp 23 and the rear clamp 24. Locking caps 251 are threadedly connected to the upper and lower parts of the anti-loosening locking rod 25, and are used to fix the anti-loosening locking rod 25.

[0018] Please see Figure 3 Two shear sleeves 32 are movably connected through the middle of the upright 3. The outer diameter of the sleeves is either an interference fit or a micro-knock fit with the holes on the upright 3. Both the inner and outer surfaces are hot-dip galvanized to improve corrosion resistance. The middle of each shear sleeve 32 is movably connected to a screw 33. The screw 33 is movably connected through the corrugated beam 1, the snap 211, and the support 21. Multiple limit rings 31 are fixedly connected to the outer wall of the upright 3. The front clamp 23 and the rear clamp 24 are in contact with the limit rings 31 to restrict the position of the front clamp 23 and the rear clamp 24.

[0019] Working principle: First, install the support member 21 on the rear side of two adjacent corrugated beams 1, so that the gasket 212 on the front side of the support member 21 contacts the rear side of the joint section of the two corrugated beams 1, while ensuring that the fastening edge 211 is fastened to the upper and lower parts of the two corrugated beams 1. Align the mounting holes on the corrugated beams 1 with the mounting holes on the support member 21. Then, fix the corrugated beams 1 and the support member 21 together with bolts. Then, clamp the front clamp 23 on the rear side of the support member 21 to the front side of the upright 3, so that its upper and lower sides contact the upper and lower limit rings 31 respectively, and clamp the rear part. After installing the clamp 24, the first locking block 231 can be inserted between the two second locking blocks 241. Then, the anti-detachment locking rod 25 passes through multiple first locking blocks 231 and second locking blocks 241, and the two locking caps 251 are tightened to the upper and lower parts of the anti-detachment locking rod 25 respectively, thereby fixing the anti-detachment locking rod 25. Then, the mounting holes on the corrugated beam 1, the support mechanism 2 and the upright 3 can be aligned, and the anti-shear sleeve 32 is installed in the hole. Then, the fixing screw 33 is installed in the anti-shear sleeve 32, thereby completing the fixing between the corrugated beam 1, the support mechanism 2 and the upright 3.
