Bridge expansion joint monitoring connecting device

Abstract

The invention discloses a bridge expansion joint monitoring connecting device which comprises a bridge body, and an expansion joint being arranged on the bridge body. mounting seats, arranged in the expansion joint, the number of the mounting seats being two, and fixing anchor bolts being arranged on one sides of the two mounting seats; and a monitoring base, arranged between the two mounting bases. Telescopic cavities are formed in the two ends of the monitoring base correspondingly, telescopic detection rods are arranged on the two sides of the monitoring base correspondingly, one end of each telescopic detection rod extends into the corresponding telescopic cavity, and a first pressure sensor is arranged in each telescopic cavity. An elastic head is arranged between the first pressure sensor and the telescopic detection rod, and the elastic head is attached to the first pressure sensor. The working performance of the bridge expansion joint is monitored, and the expansion joint can be repaired in time, so that the use effect of the bridge expansion joint is ensured, vehicles pass stably, and the safety performance of vehicle passing is improved.

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
