Abstract

The invention relates to a sliding block structure for preventing horizontal displacement of a bridge support. The sliding block structure comprises a sliding block (1), first stop blocks (2) arrangedin pairs and second stop blocks (3) arranged in pairs, the first stop blocks (2) and the second stop blocks (3) are located at the top of the sliding block (1), the first stop blocks (2) arranged inpairs are arranged on the left side and the right side of the second stop blocks (3) respectively, and an accommodating cavity (4) for accommodating the bridge support (5) is formed between the pairedfirst stop blocks (2) and the paired second stop blocks (3). Compared with the prior art, movement of the bridge support can be limited, and the sliding block structure is simple in structure, easy to manufacture and capable of being used for mastering the health state of a bridge in real time.

Description

technical field

[0001] The invention belongs to the field of bridge engineering, and in particular relates to a sliding block structure for preventing horizontal displacement of bridge bearings. Background technique

[0002] As an important social infrastructure, bridges have the characteristics of large investment, strong publicity, and difficult maintenance and management. At the same time, bridges are an important part of the earthquake-resistant and disaster-prevention management system. Improving the seismic performance of bridges is one of the most important basic measures to reduce earthquake losses and strengthen regional safety. Generally, limit blocks (i.e. sliding blocks) are set between adjacent bridge supports (the supports are located at the bottom of the bridge) to prevent the bridge supports from slipping out and falling beams. This sliding block is a trapezoidal column with an upper width of Narrow bottom, located in the middle of the bridge support, adjace...

Embodiment

[0030] Such as figure 1 , 2 , shown in 3, a kind of sliding block structure that prevents the horizontal displacement of bridge support, comprises sliding block 1, the first block 2 that is arranged in pairs and the second block 3 that is arranged in pairs, the first block 2 and the second stopper 3 are all located on the top of the sliding block 1, and the paired first stoppers 2 are respectively arranged on both sides of the second stopper 3 on the left and right, the sliding block 1 is in the shape of a cuboid, and the paired The first block 2 is symmetrical about the axis along the width direction of the sliding block 1, and the pair of second blocking blocks 3 are symmetrical about the axis along the length direction of the sliding block 1. The top of the second blocking block 3 and the first The top of a block 2 is flush (that is, the right-angled side on the vertical direction of the right triangle is consistent with the height of the first block 2), and the sides are ...
