Bridge static load test deflection dial indicator measuring and connecting device

Abstract

The invention relates to a bridge static load test deflection dial indicator measuring and connecting device and belongs to bridge engineering technologies.The device comprises a steel wire, a steel beam and a V-shaped spring; the V-shaped spring is formed by bending a long spring by 120-150-degree-angle from the middle to form connectors, the other ends of the spring are connected with the two ends of the steel beam respectively, and the steel wire is connected to the middle of the steel beam; the steel wire is provided with LED alarm lamps; the device further comprises a dial indicator, pointers of the dial indicator make contact with the center of the steel beam, and the dial indicator is fixed to the ground and the inverted bridge face through a magnetic meter seat.By means of the bridge static load test deflection dial indicator measuring and connecting device, deflection measuring becomes convenient, fast and free of limitation of the bridge environment, and influence factors of result precision are reduced.

Description

technical field [0001] The invention relates to a bridge static load test deflection dial indicator measuring connection device, which belongs to the bridge engineering technology. Background technique [0002] Bridges are key nodes in the national transportation network, and their safety is extremely important. Therefore, bridge workers need to frequently inspect and evaluate the safety of bridges. In the current inspection and evaluation, the static load test method is usually used to evaluate the bearing capacity and safety of the bridge, and an important parameter in the evaluation is the deflection measurement value of the key section of the bridge. Traditionally, the deflection of the key section of the bridge is measured with a level gauge. This method requires a level gauge and a leveling rod to measure the height difference between two points on the ground. However, this method requires at least 2 people and is labor-intensive. At the same time, the test accuracy is...

AI Technical Summary

Problems solved by technology

The deflection of the key section of the traditional test bridge is measured by a level instrument. This method requires a level instrument and a leveling rod to measure the height difference between two points on the ground. However, this method requires at least 2 people and is labor-intensive. At the same time, the test accuracy is affected by the level instrument’s own accuracy and the readings of the testers. The deviation, the accuracy of the leveling rod itself, and the operating deviation of the staff supporting the leveling rod are greatly affected
