Installation structure and installation method for perpendicularity sensor on overlong square tubular column

Abstract

The invention discloses an installation structure and an installation method for a perpendicularity sensor on an overlong square tubular column. The installation structure comprises a laser inclinometer internally provided with a perpendicularity sensor and a laser emitter, a regulating plate, a right-angled bending plate, a light target, a coarse tuning bolt component and a fine tuning bolt component, wherein the laser of the laser emitter is parallel to a measuring baseline of the perpendicularity sensor; through holes for emitting laser are correspondingly formed in a laser inclinometer connecting plate and the regulating plate; the position of the regulating plate is regulated by virtue of the coarse tuning bolt component and the fine tuning bolt component, so that the position of the laser on the light target is unchanged when the light target is arranged on different installation baselines, and the laser emitted after the laser inclinometer is installed and fixed is parallel to the axis of the square tube column. The installation structure can be used for solving the installation and positioning problem of the perpendicularity sensor on the square tube column in an automatic test method of the perpendicularity sensor, realizing the convenient and accurate detection of the square tube column, and realizing the real-time detection of the perpendicularity of the overlong square tube column.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an installation structure and method of a verticality sensor on a super-rectangular pipe column. Background technique [0002] With the development of the city, the construction technology has also been developed rapidly. Compared with the traditional open method, the upside-down method has the advantages of reducing foundation pit deformation, saving support costs, and shortening the construction period. It is an energy-saving and environmentally friendly green construction method. is widely adopted. However, the reverse construction method has higher requirements for the square pipe string, that is, the square pipe string must maintain sufficient verticality to withstand sufficient vertical axial force under the design section. Therefore, the verticality of the square pipe string is required to reach 1 / 500, 1 / 600 or higher. [0003] The verticality detection methods of t...
