Pier beam buffer structure and anti-seismic bridge

Abstract

The invention relates to the technical field of bridge structures, and particularly relates to a pier beam buffer structure and an anti-seismic bridge. The pier beam buffer structure comprises a pierand a main beam; the top face of the pier is higher than the bottom face of the main beam; a mounting groove is formed in the top of the pier; the bottom of the main beam is located in the mounting groove, and shockproof buffer cushion blocks are arranged between the two sides of the main beam and the mounting groove and can reduce mutual collision and extrusion between the main beam and the pierunder the action of earthquake force; the anti-seismic bridge comprises a main beam, piers and a bearing platform; the main beam is connected with the piers through the pier beam buffer structure; thebottoms of steel pipes are connected with bearing plates; a plurality of rib plates are arranged between the bearing plates and the steel pipes; each rib plate is provided with a plurality of first through holes; the bearing platform is provided with a preformed groove; the bottoms of the piers are located in the preformed groove, and concrete is poured into the preformed groove, so that the piers and the bearing platform are connected more reliably, the stability of the bottoms of the piers is enhanced, and the safety and stability of the bridge structure are improved.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a pier-beam buffer structure and an anti-seismic bridge. Background technique [0002] The bridge pier is a building that supports the bridge span structure and transmits the load to the foundation. It not only needs to bear all the loads transmitted by the bridge span structure, but also directly bears various loads such as earth pressure or water flow impact, so the bridge pier itself has sufficient strength. , rigidity and stability, the solid structure of stone masonry, concrete or steel tube concrete is generally adopted. [0003] Such as figure 1 As shown, in a common bridge structure, the main girder 1 is arranged above the support 6, the top surface of the pier 2 is provided with a pad stone 7, the support 6 is connected with the pad stone 7, and the support 6 is used to reliably transfer the main girder 1 and the load borne by the main girder 1 to the pier 2 ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to: in the high-intensity earthquake area that exists in the prior art, due to the effect of the earthquake force, the bridge will produce a large seismic response, and the main girder and the bridge pier may have a large displacement or even separation, which will damage the bridge. Structural problems, providing a pier-beam buffer structure and an earthquake-resistant bridge with better seismic performance
