Problems solved by technology

Therefore, the existing method is mainly used for short-term measurement of the micro-stress of bridge structural materials. When measuring again after a period of time, it needs to unload and recalibrate the zero point. The measurement error is large and the drift is serious. It is not suitable for long-term continuous monitoring.
In addition, the welding method can only weld the edge of the sensitive element, and cannot achieve surface contact, and the welding temperature usually damages the sensitive element

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 and figure 2 As shown, the bearing elastic body used to measure the bridge load in this embodiment includes an elastic body 1, and a blind hole 2 is provided on the bottom surface of the elastic body 1, and a vertical and fastening installation for detecting elasticity is installed in the blind hole 2. The stress detection part 3 of the body body 1 stress. The support elastic body used for measuring bridge loads of the present invention combines stress detection with the elastic body body, opens a blind hole 2 on the bottom surface of the elastic body body 1, and arranges a stress detection member 3 in the blind hole 2, The stress borne by the elastic body 1 can be directly measured, so as to obtain the load of the bridge, and the measurement is accurate and reliable; in addition, the stress on the elastic body 1 will...

Abstract

The invention discloses a supporting base elastic part used for measuring the bridge load. The supporting base elastic part comprises an elastic part body. A blind hole is formed in the bottom face of the elastic part body. A stress detection part used for detecting stress of the elastic part body is vertically installed in the blind hole in a fastened mode. The supporting base elastic part used for measuring the bridge load has the advantages of being simple in structure, stable, reliable, precise in measurement and the like.

Description

technical field [0001] The invention mainly relates to the technical field of bridges, in particular to a bearing elastic body used for measuring bridge loads. Background technique [0002] At present, damage and collapse accidents of bridges due to design and construction quality, or changes in geographical environment and natural environment occur frequently. Bridge safety and health monitoring has always been a hot research topic at home and abroad. [0003] The bridge support is installed at the junction of the bridge deck and the bridge pier, connected to the bridge deck at the top and the pier at the bottom, which is the concentrated part of the bridge load. The elastic body in the bearing is the main body of the bearing structure of the bearing and also the main body of bearing the pressure of the bridge deck. Stress detection of bridge structural materials is the main content and difficulty of bridge safety monitoring. Among them, the composition of bridge structur...
