Combined anti-corrosion supporting device for transverse seismic resistance of bridge

Abstract

The invention discloses a combined anti-corrosion supporting device for transverse seismic resistance of a bridge, which comprises an outer supporting device, an inner supporting device and a polyurethane anti-corrosion coating. The outer supporting device is composed of a stable base, fixing groove holes, anti-oxidation spring pieces, elastic-plastic steel dampers, drainage channels, a supporting shell, reinforcing ribs, connecting inner groove holes and limiting clamping grooves, the fixing groove holes are symmetrically formed in the four side faces of the stable base, and the anti-oxidation spring pieces are symmetrically arranged at the top of the stable base; elastic-plastic steel dampers are symmetrically arranged in the middles of the anti-oxidation spring pieces, drainage channels are symmetrically formed in the two sides of each elastic-plastic steel damper, a supporting shell is arranged at the top end of the stable base, the supporting shell and the stable base are punched into a whole, and reinforcing ribs are symmetrically arranged on the four side faces of the supporting shell. The combined type anti-corrosion supporting device for transverse seismic resistance of the bridge has the advantages of being convenient to combine, high in stability, high in seismic resistance and high in corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of supporting devices, in particular to a combined anti-corrosion supporting device used for transverse seismic resistance of bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the transportation industry, bridges are also extended to cross mountains, poor geology, or to meet other traffic needs. Buildings that make traffic more convenient. Bridges are generally composed of superstructure, substructure, supports and auxiliary structures. The superstructure is also called bridge span structure, which is the main structure for crossing obstacles. The substructure includes abutments, piers and foundations. Or the force transmission device installed at the supporting place of the bridge abutment, and the auxiliary structures refer to the bridgehead board, conical slope protection...

AI Technical Summary

Problems solved by technology

[0003] The aseismic performance of bridges needs to be considered during construction, especially for bridges built in earthquake areas. However, practice shows that more attention is paid to the longitudinal aseismic performance in bridge construction. The existing bridge support structures are relatively simple to deal with bridge lateral vibration. As a result, the lateral seismic effect is poor. When lateral vibration occurs, it cannot have a buffering effect, and it is easy to cause damage to the bridge body and the bridge support structure, affecting the normal use of the bridge, and the bridge support device is easy to withstand weather erosion for a long time. Damaged by corrosion, seriously affecting safety
