Problems solved by technology

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 The bottom is narrow, located in the middle of the bridge support, adjacent to the fulcrum, which can hinder the lateral deviation of the bridge support, but cannot limit the longitudinal displacement of the bridge support

Embodiment

[0030] like figure 1 , 2 As shown in , 3, a sliding block structure for preventing the horizontal displacement of the bridge bearing includes a sliding block 1, a pair of first stoppers 2 and a pair of second stoppers 3. The first stopper 2 and the second block 3 are both located on the top of the sliding block 1, and the paired first blocks 2, one left and one right, are respectively arranged on both sides of the second block 3. The first stopper 2 is symmetrical with respect to the axis of the sliding block 1 along the width direction, and the paired second stoppers 3 are symmetrical with respect to the axis of the sliding block 1 along the length direction. The top of the first stopper 2 is flush (that is, the right-angled side of the right-angled triangle in the vertical direction is the same as the height of the first stopper 2), and the sides are also flush, so that the two first stoppers 2 and the two The second block 3 forms a structure in which a large rectangle wra...

Abstract

The invention relates to a sliding block structure for preventing the horizontal displacement of a bridge support. The sliding block structure comprises a sliding block (1), first stop blocks (2) arranged in pairs, and second stops arranged in pairs block (3), the first stopper (2) and the second stopper (3) are located at the top of the sliding block (1), and the paired first stoppers (2) are respectively located on the left and right On both sides of the second block (3), an accommodating cavity (4) for accommodating the bridge support (5) is formed between the paired first block (2) and the paired second block (3). Compared with the prior art, the invention is beneficial to limit the movement of the bridge support, has a simple structure, is easy to manufacture, and can be used to grasp the health status of the bridge in real time.

Description

technical field [0001] The invention belongs to the field of bridge engineering, in particular to a sliding block structure for preventing the horizontal displacement of a bridge bearing. Background technique [0002] As an important social infrastructure, bridges have the characteristics of large investment, strong publicity, and difficult maintenance and management. Bridges are also 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 (ie sliding blocks) are set between adjacent bridge supports (the supports are located at the bottom of the bridge) to prevent the bridge supports from sliding out and falling off the beam. This sliding block is a trapezoidal column with a wide upper The bottom is narrow, located in the middle of the bridge support, adjacent to the fulc...
