Structure and method for installing perpendicularity sensor on ultralong tubular pillar

Abstract

The invention discloses a structure and method for installing a perpendicularity sensor on an ultralong tubular pillar. The structure comprises a laser gradiograph, a coarse adjusting bolt assembly, a fine adjusting bolt assembly, a light target, an installing bottom plate, an adjusting plate and a right-angle bent plate, and the perpendicularity sensor and a laser transmitter are arranged in the laser gradiograph. The perpendicularity sensor can measure the included angle between a measuring datum line and a natural vertical line. The laser of the laser transmitter is parallel to the measuring datum line of the perpendicularity sensor. The position of the adjusting plate is adjusted through the coarse adjusting bolt assembly and the fine adjusting bolt assembly so that when the light target is installed on different datum lines, the position of the laser on the laser target cannot be changed, and the laser transmitted after the laser gradiograph is installed and fixed is parallel to the axis of the tubular pillar. The problem of installing and positioning of the perpendicularity sensor on the ultralong tubular pillar is solved, it is ensured that the laser transmitted by the laser gradiograph is parallel to the axis of the tubular pillar, the measuring precision of the laser gradiograph is guaranteed, and the perpendicularity adjusting construction of the tubular pillar is more convenient and accurate.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a fast installation structure and an installation method of a verticality sensor of a lattice column of a column of one pile in reverse construction on a super-rectangular lattice 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 steel pipe columns (including circular pipe columns and circular pipe columns), that is, steel pipe columns are required to maintain sufficient verticality to withstand sufficient vertical axial force under the design sec...

AI Technical Summary

Problems solved by technology

Another verticality measurement method is usually to install a sensor in the X direction and Y direction on the upper end of the steel pipe column. In the initial measurement, a zero return operation is required, and the steel pipe column is usually hoisted for operation. Such a process is cumbersome to operate, time-consuming, laborious, and efficient. very low

After the final vertical adjustment, the verticality of the steel pipe column is still difficult to reach 1 / 500, 1 / 600 or higher
