Problems solved by technology

The beam body often has a large displacement and friction on the support, which is a kind of damage to the beam body, support, and bridge piers. At the same time, the large lateral displacement of the bridge will affect the force of the bridge and reduce the life of the bridge.

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the embodiment given with accompanying drawing.

[0026] Such as Figure 3-4 , an assembled blocking device for resisting lateral displacement of a bridge, comprising a beam bottom fixing member 1 and a pier top fixing member 2, and a limiting second is formed between the beam bottom fixing member 1 and the pier top fixing member 2 The limiting structure for relative lateral displacement between them. When in use, the blocking device is arranged on the left and right sides of the support 6, the fixed member 1 at the bottom of the beam is fixedly installed on the bottom surface of the box girder 4, the fixed member 2 is fixedly installed on the top surface of the pier 5, and the fixed member at the bottom of the beam 1 and the pier top fixing member 2 are formed with a limiting structure that limits the relative lateral displacement between them, thus, through the limiting structure, the...

Abstract

The invention relates to an assembly type blocking device for transverse displacement resistance of a bridge and an installation method of the assembly type blocking device. The blocking device comprises a beam bottom fixing component and a pier top fixing component, and a limiting structure for limiting relative transverse displacement between the beam bottom fixing component and the pier top fixing component is formed between the beam bottom fixing component and the pier top fixing component. A limiting structure for limiting relative transverse displacement between the beam bottom fixing component and the pier top fixing component is formed between the beam bottom fixing component and the pier top fixing component, and therefore transverse displacement between a bridge and a pier can belimited through the limiting structure, influences on the service life of the bridge due to transverse displacement of the bridge are reduced, and the service life of the bridge is prolonged.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to an assembled blocking device for resisting lateral displacement of bridges and an installation method thereof. Background technique [0002] In the prior art, the way to limit the lateral displacement of the bridge girder is mainly in the form of adding concrete stoppers, but the method of adding stoppers to limit the lateral displacement is mainly used in the form of bridges with covered beams, such as figure 1 , the cover beam 7 is straddled on the pier 5, and a plurality of T beams 8 are longitudinally arranged on the cover beam 7, and a stopper 9 is respectively arranged on the outer sides of the two T beams on the left and right sides, so that The lateral displacement of the T-beam 8 is limited by the stopper 9, that is, the bridge with the cover beam 7 limits the upper beam body such as T-beam, small box girder, etc. by adding a stopper 9 at the end of the cover beam 7. ...
