Description

Technical Field

[0001] This utility model belongs to the field of bridge railing technology, and in particular relates to an earthquake-resistant steel structure bridge railing. Background Technology

[0002] Bridge railings are railings installed on bridges to prevent out-of-control vehicles from going off the bridge. They also serve to prevent vehicles from breaking through, passing under, or overturning the bridge, and to beautify the bridge structure.

[0003] For example, Chinese patent CN207944335U discloses a bridge railing, which includes: a concrete base set on the bridge deck, a plurality of spaced columns embedded in the concrete base, and a plurality of crossbeams, each crossbeam being fixedly connected to the plurality of columns; wherein, along the height direction, the spacing between adjacent crossbeams gradually increases with the increase of height.

[0004] This patent has the following problems:

[0005] Existing technologies are inconvenient for seismic installation on bridges. Vehicle traffic causes vibrations, potentially leading to swaying of the guardrails and reducing their stability. Furthermore, existing technologies are not suitable for high-level protection, making it difficult to intercept vehicles at higher elevations in the event of a collision, thus compromising safety. Therefore, we propose a seismic-resistant steel bridge guardrail. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned technical problems by providing an earthquake-resistant steel structure guardrail for bridges, thereby improving the stability and safety of the guardrail.

[0007] In view of this, the present invention provides a seismic-resistant steel structure guardrail for bridges, including a bottom support rod, and further comprising: a pier fixedly installed at the bottom of each bottom support rod, a supporting base block fixedly installed at the top of each pier, a bottom buffer block fixedly installed at the top of each supporting base block, a top buffer block fixedly installed at the top of each bottom buffer block, anchor bolts through the interior of each pier, upper and lower connecting rods fixedly installed at the top of each bottom support rod, a top support rod fixedly installed at the top of each upper and lower connecting rod, a top connecting plate fixedly installed between each top support rod, and a top protective rod fixedly installed between each top connecting plate.

[0008] Based on the above structure, the piers are fixed to the top of the bridge with anchor bolts, and then supported by the bottom support blocks. Next, the bottom buffer blocks and top buffer blocks are used for shock absorption. When the guardrail is installed on the top of the bridge, the bottom buffer blocks and top buffer blocks filter the vibration of the traffic flow, thereby improving the stability of the guardrail. Then, the top connecting plate is used to connect multiple top guardrails for protection. In the event of a collision between vehicles on the bridge, the top guardrails can be used for protection and interception, thereby improving the safety of the guardrail.

[0009] Preferably, the bottom support rod is made of steel, and a bottom connecting rod is fixedly installed between the bottom support rods.

[0010] Preferably, a bottom frame is fixedly installed at the bottom of the bottom connecting rod, and bottom frame rods are fixedly installed inside the bottom frame.

[0011] Preferably, a bottom protective rod is fixedly installed at the bottom of the bottom frame, an anti-corrosion paint plate is fixedly installed at one end of the bottom protective rod, and a waterproof plate is fixedly installed at the other end of the anti-corrosion paint plate.

[0012] Preferably, an inner protective plate is fixedly installed on the surface of the bottom protective rod, an inner buffer plate is fixedly installed on the surface of the inner protective plate, and an inner rubber plate is fixedly installed on the surface of the inner buffer plate.

[0013] Preferably, a connecting cylinder is fixedly sleeved on the outside of both the upper and lower connecting rods, and a connecting hole is provided through the inside of each connecting cylinder.

[0014] Preferably, a handrail is fixedly installed on the top of the top support rod, and a handrail sleeve is fixedly fitted on the outside of the handrail, and a rubber handrail sleeve is fixedly fitted on the outside of the handrail sleeve.

[0015] The beneficial effects of this utility model are:

[0016] 1. This earthquake-resistant bridge steel structure guardrail uses anchor bolts to fix the piers to the top of the bridge, and then uses supporting blocks for support. Next, bottom buffer blocks and top buffer blocks are used for shock absorption. When the guardrail is installed on the top of the bridge, the bottom buffer blocks and top buffer blocks filter the vibration of traffic flow, making the guardrail less prone to shaking, thereby improving the stability of the guardrail.

[0017] 2. This earthquake-resistant steel structure bridge railing connects multiple top guardrails through a top connecting plate. In the event of a collision between vehicles on the bridge, the top guardrails can be used to protect and intercept the vehicles, making it less likely for vehicles and people to fall off the bridge, thereby improving the safety of the railing.
