Elastic limiting stopper for bridge deviation rectification and bridge with automatic deviation rectification function

Abstract

The invention discloses an elastic limiting stopper for bridge deviation rectification and a bridge with an automatic deviation rectification function. The elastic limiting stopper comprises a main structure and an auxiliary structure, the main structure comprises a frame, a carbon steel fixing frame is installed at the center of the interior of the frame, a main telescopic column is installed at the top of the carbon steel fixing frame, and the main telescopic column is sleeved with a main limiting spring; a main bearing plate is installed at the top of the main telescopic column through screws, grooves are formed in the two sides of the bottom end of the main bearing plate, sliding blocks are installed in the grooves, a set of reset springs are installed on the two sides of each sliding block through fixing pieces, and the other ends of the reset springs are connected with the inner walls of the grooves through fixing pieces;and the top of the main structure is provided with the auxiliary structure through screws. According to the elastic limiting stopper for bridge deviation rectification and the bridge with the automatic deviation rectification function, the bearing capacity and the horizontal deformation capacity of the bridge can be improved, the possibility of deformation of the bridge is prevented, and the overall safety performance of the bridge is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an elastic limiter for bridge deviation correction and a bridge with automatic deviation correction function. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to 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. The force transmission device installed at the support of the span structure and the bridge pier or bridge abutment, and the auxiliary stru...

Problems solved by technology

[0003] During the construction process or long-term use, there will be deviation between the bridge and the pier column, which needs to be rectified and reset. If it is not repaired for a long time, the bridge will deviate or cause the possibility of collapse. The existing measures are basically through hydraulic pressure. The jack cooperates with other mechanical equipment to repair, which is not only difficult in construction, but also time-consuming and labor-intensive. Therefore, we have improved this and proposed an elastic limiter for bridge deviation correction and a bridge with automatic deviation correction function.
