Bridge expansion joint monitoring connection device

Abstract

The invention discloses a bridge expansion joint monitoring connection device, which comprises a bridge body, on which an expansion joint is arranged; One side of the mounting seat is provided with fixed anchor bolts; the monitoring seat, the monitoring seat is arranged between two mounting seats, the two ends of the monitoring seat are provided with expansion chambers, and the two sides of the monitoring seat are provided with A telescopic detection rod, one end of the telescopic detection rod extends to the inside of the telescopic chamber, a first pressure sensor is arranged inside the telescopic chamber, an elastic head is provided between the first pressure sensor and the telescopic detection rod, and the The elastic head is attached to the first pressure sensor. It realizes the monitoring of the working performance of the bridge expansion joints, and can repair the expansion joints in time, thereby ensuring the use effect of the bridge expansion joints, making the vehicle traffic smooth, and improving the safety performance of the vehicle traffic.

Description

technical field [0001] The invention relates to the technical field of monitoring bridge expansion joints, in particular to a monitoring connection device for bridge expansion joints. Background technique [0002] Construction expansion joints are expansion joints, which refer to a structural joint set at an appropriate position along the construction joint direction of a building or structure in order to prevent cracks or damage to the structure due to climate temperature changes. Building components such as walls, floors, roofs, etc. are divided into two independent parts, so that buildings or structures can be stretched horizontally along the long direction. It is very important to reasonably select the gap with the proper amount of expansion and contraction. The larger the gap, the easier it is to damage the expansion device. The gap used is too large or too small, and the gap is adjusted without considering the temperature during installation. Especially for the plate...

AI Technical Summary

Problems solved by technology

[0003] At present, after the bridge expansion joints have been used for a period of time, it is easy to cause deviations in the bridge expansion joints after a large number of vehicles pass. If the bridge expansion joints with poor use effects cannot be repaired in time, it is easy to cause the vehicle to jump when the vehicles pass, and the bridge expands. Joint stress buffering and release is not complete, which greatly increases the load of bridge expansion joints, which easily leads to safety accidents
