Assembly type steel support axial force monitoring assembly

Abstract

The invention discloses an assembly type steel support axial force monitoring assembly. The assembly type steel support axial force monitoring assembly comprises a fixed part, a monitoring element and a movable part, wherein the fixed part is fixed at the end part of a steel support and provided with a central sleeve extending outwards along the axial direction of the steel support; the monitoring element is placed in the central sleeve; and the movable part is provided with a jacking pipe which is matched with the interior of the central sleeve and is provided with a sealed end part, and the jacking pipe is inserted into the central sleeve. According to the assembly type steel support axial force monitoring assembly, the monitoring element is arranged in the central sleeve of the fixed part, and the jacking pipe of the movable part is inserted into the central sleeve; the fixed part compresses the movable part under the action of the axial force of the steel support, meanwhile, the jacking pipe compresses the monitoring element under the action of the counter-acting force, real-time monitoring of the axial force of the steel support is achieved, the monitoring element is arranged inside, installation is stable, the monitoring element is not affected by the external environment, and monitoring data are accurate; the whole structure is convenient to disassemble and assemble and can be repeatedly used; and the steel support and a steel enclosing purlin are in matched contact through the center sleeve and the jacking pipe, and the steel support is not prone to falling off.

Description

technical field [0001] The invention relates to the field of steel support monitoring, in particular to an assembled steel support axial force monitoring component. Background technique [0002] With the rapid development of cities, the development of underground space and urban rail transit are showing a momentum of rapid development. Restricted by the surrounding environment during the construction of deep foundation pits in cities, the support form of retaining piles / walls plus internal steel supports is widely used during construction. [0003] At present, in the construction process of the steel support support site, the general design drawings do not give detailed methods and the installation is not standardized. Therefore, real-time monitoring of the axial force of steel supports often becomes a controlling factor for safe construction of foundation pits. [0004] For the monitoring of the axial force of the steel support, the common practice in current engineering ...

AI Technical Summary

Problems solved by technology

[0005] 1. The placement of the pressure box is not standardized, and the axial force monitoring data is inaccurate;

[0006] 2. The contact between the steel support and the steel purlin is only through the pressure box, which may easily cause the steel support to fall off;

[0007] 3. The excavation and restoration of the entire foundation pit takes a long time, there are many influencing factors, and the pressure box is damaged
