Abstract

The invention relates to a novel instrument for measuring the gradient of a steel column. The instrument comprises a laser emitter, a plumb bob, a basic length scale, a telescopic length scale, a basic angle scale, a telescopic angle scale and a fixed angle scale; the instrument is characterized in that both the laser emitter and the plumb bob are mounted at an end part of the telescopic length scale; the other end of the telescopic length scale is integrally inserted into the basic length scale; one end of the basic length scale is fixed with one end of the basic angle scale; the fixed angle scale is mounted at an included angle between the basic length scale and the basic angle scale; one end of the telescopic angle scale is integrally inserted into the basic angle scale. The invention provides the instrument for measuring the mounting gradient of the inclined steel column, overcomes deficiencies of a conventional process in aspects of personnel operation and data acquisition, and improves the mounting efficiency of the special-shaped steel column; the instrument is scientific, reasonable, and simple, convenient and quick to implement.

Description

technical field [0001] The invention relates to a novel steel column slope measuring instrument. Background technique [0002] In modern steel structure buildings, more and more special-shaped steel structures are used, which causes many difficulties in the installation of steel structures. According to the requirements of Article 11.4.1 of the "Code for Construction of Steel Structure Engineering" (GB50755-2012), the inclined steel column can be measured and corrected by three-dimensional coordinate measurement method, or by the projection point of the column top combined with the elevation, and the calibration is qualified. Then it is fixed with a rigid support. For the hoisting and positioning of a special-shaped structural steel column, the traditional wire hammer method and total station measurement method cannot meet the requirements of rapid installation in terms of work efficiency and accuracy. First of all, these two measurement and calibration processes require m...
