High-performance bridge reinforcing device for building construction

Abstract

The invention provides a high-performance bridge reinforcing device for building construction, and relates to the technical field of bridges. Problems that a fixing hoop is only fastened through boltsto achieve a fixing purpose, and auxiliary fixing except for the hoop cannot be achieved by fastening the fixing bolts and other auxiliary structures to achieve the purpose of improving a fixing effect are solved. And the problem that the fastening bolt is easily broken due to an overlarge stress is solved too. The high-performance bridge reinforcing device for building construction comprises a supporting column. A bridge plate is welded to the top end surface of the supporting column. A head end of a shifting seat is in contact with an ejector rod, and the head end of the shifting seat is aninclined structure; and after the fastening bolt is fastened, the ejector rod is in an exposed state under extrusion of the shifting seat, the head end of the ejector rod makes contact with the outerwall of the supporting column, and therefore auxiliary fixing of the fixing seat structure is achieved.

Description

technical field [0001] The invention belongs to the technical field of bridges, and more specifically relates to a high-performance bridge reinforcement device for building construction. Background technique [0002] Bridge reinforcement is to improve the bearing capacity and service performance of components and even the entire structure through certain measures to meet new requirements. That is to say, it is necessary to deal with the situation that the bridge cannot meet the continuous use. [0003] For example, the application number: CN201611091288.3, ​​the present invention relates to a bridge reinforcement device, including a bridge beam, a lower floor is arranged at the bottom of the bridge beam, and piers are arranged at both ends of the lower floor, and the bottom of the bridge piers is fixedly supported by a supporting pier and a base, and the bridge piers and the bridge An inclined support plate is arranged between the beams; a transverse support plate is arrang...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a high-performance bridge reinforcement device for building construction to solve the problem that the main body of the fixing seat of the existing device is mostly a hoop structure, and the fixing hoop is only fixed by bolts. If fastening is used to achieve the purpose of fixing, the fixing effect is poor, and it is impossible to achieve the purpose of improving the fixing effect by tightening fixing bolts and other auxiliary structures except for clamps; moreover, the current support arm Most of the fixing seats are only fastened by bolts when they are fixed. When the force is too large, the fastening bolts are likely to break, and then the supporting effect is lost.
