Residential building steel column perpendicularity measuring method and special platform thereof

Abstract

The invention relates to a residential building steel column perpendicularity measuring method. A coordinate system is newly built on a certain steel column in an elevator shaft; a measuring instrument platform is arranged at the highest steel beam position in the elevator shaft, a total station is fixed, and a reverse point platform and a reverse point are arranged below the measuring instrument platform; a design coordinate of a top end corner point of the to-be-measured steel column is calculated; vertex measurement coordinates of the steel column are measured by using a total station; the measurement coordinates are compared with the design coordinates; the invention further provides a platform special for the residential building steel column perpendicularity measuring method. The periphery of the measuring instrument platform is connected with cross beams on the four faces of an elevator shaft through connecting pieces; the point reversing platform is mounted on a cross beam from the elevator opening side to the opposite side. According to the scheme, the total station is arranged in the elevator shaft, the point is higher than the steel column to be measured to achieve depression angle measurement, and due to the fact that the view of the total station is not hindered, the perpendicularity of all the steel columns can be observed through one station; the platform does not depend on the civil construction progress of the floor, and the risk after the construction period is effectively reduced.

Description

technical field [0001] The invention belongs to the construction precision detection technology of structural columns, in particular to a method for measuring the verticality of residential building steel columns and a special platform thereof. Background technique [0002] Steel structure buildings are a new type of building system. Compared with traditional concrete buildings, steel plates or section steel are used instead of reinforced concrete, which has higher strength and better earthquake resistance. And because the components can be manufactured in a factory and installed on site, the construction period is greatly reduced. Due to the reusable use of steel, construction waste can be greatly reduced, and it is more environmentally friendly, so it is widely adopted by countries all over the world and used in industrial buildings and civil buildings. [0003] In steel structure residential buildings, it is necessary to correct the verticality of steel columns when they...
