Abstract

The invention discloses a bridge expansion joint width monitoring and early warning device, relates to the technical field of bridge expansion joint detection devices, and solves problems that most ofexisting detection devices and monitoring mechanisms cannot conveniently implement telescopic adjustment and cannot be suitable for being inserted into bridge connecting pieces with different spacingwidths to monitor different telescopic gaps. The bridge expansion joint width monitoring and early warning device comprises a telescopic connecting piece, the whole telescopic connecting piece is composed of a left half part and a right half part, the telescopic connecting piece is installed in a butt joint gap between the ends of two bridges in a poured mode, and the monitoring and early warningdevice is inserted into a gap between the left half part and the right half part of the telescopic connecting piece. Four square connecting rods are jointly and rotationally connected to form rhombusmain body framework of the device, and a rectangular mounting cavity is formed in each of the four square connecting rods in a penetrating mode. Transverse telescopic gaps between bridges can be monitored, the up-down dislocation distance between the bridges can be monitored, one device has two purposes, the monitoring function is diversified, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of bridge expansion joint detection devices, in particular to a bridge expansion joint width monitoring and early warning device. Background technique [0002] Bridge expansion joints are an integral part of the bridge structure. If the design is unreasonable, the construction quality cannot meet the standards, and the maintenance method is unscientific, these will cause damage to the expansion device of the bridge to varying degrees, resulting in beams on both sides of the expansion joints. The height difference will cause cracks on the road surface, and the vehicle will jump and impact when passing, which will cause additional impact loads on the bridge and the road surface, and make the driver feel uncomfortable. Seriously, it may lead to traffic accidents. Thus affecting the normal life and operation of highway bridges. In order to meet the requirements of deformation and longitudinal displacement of th...
