Problems solved by technology

During the actual installation process of the above prior art detection device, due to the above-mentioned small installation block and the hard and heavy reasons, it is necessary to manually press the two small installation boards before installing the sensor for 30-40 minutes to stick them together. Its labor intensity is very high, it takes up too much manpower time, and its installation and construction efficiency is low; and there are phenomena such as the movement of the base position during the manual lifting process, which affects the installation accuracy, and the detection process is interrupted due to weak bonding

Abstract

The invention discloses an installation structure and an installation method of a concrete stress strain detection device. The installation structure of the concrete stress strain detection device comprises two small installation plates adhered to a concrete surface of a stress strain concentration region and used for installing sensors, and two large installation plates adhered to concrete surfaces of two sides of the two small installation plates, wherein a sensor protection cover is arranged on the two large installation plates and is detachably connected with the two large installation plates; pressing devices, i.e. two pressing pillars aiming at the two small installation plates are detachably arranged in the sensor protection cover; and the two pressing pillars align at the two smallinstallation plates, and meanwhile, the sensor protection cover is screwed down through locking nuts, so that the pressing pillars apply pressure on the two small installation plates. The installation structure and the installation method endow the sensor protection cover with novel functions and actions, no manual pressing is needed, and the installation can be carried out simply and conveniently in a labor-saving way, and the installation construction efficiency is high.

Description

technical field [0001] The invention relates to the technical field of civil engineering structure detection, in particular to an installation structure and an installation method of a concrete stress and strain detection device. Background technique [0002] Civil engineering structures such as bridges, tunnels and wharves will be damaged to a certain extent with the increase of service life and changes in geological conditions. Generally speaking, when this phenomenon is relatively light, it will not affect civil engineering structures and vehicles on them and For the safety of human life, it is not necessary to deal with it first, but a detection device such as a strain sensor electrically connected to an information processing unit can be installed in the stress and strain concentration area to monitor the stress and strain development status at all times. In order to prevent structural damage caused by perforated installation, the current detection device in the prior a...
