Embodiment

[0024] refer to Figure 1 to Figure 4 , this embodiment provides an installation method for inclined support steel columns, the method is to use modern information technology to obtain the precise coordinates of the key points of the components in place, and then use machinery to hoist the inclined steel column 1 and roughly adjust it to the design position through the reverse chain , the rotary machine is installed in place and temporarily connected with bolts. Through fine-tuning measures, under the observation of the three-dimensional space coordinates of high-precision instruments, the correction of the steel column is completed, and the subsequent structure is connected in time to form a stable system.

[0025] Specific steps are as follows:

[0026] 1) Determine the key points and calculate the precise coordinates of the key points

[0027] Determine the top end point and bottom end point of the upper end face of the inclined steel pipe column 1 as key points A and key ...

Abstract

The invention provides a mounting method of an inclined supporting steel column. The method comprises the following steps of: obtaining accurate coordinates of a component in-place key point by utilizing a modern information technology; hoisting an inclined steel pipe column by utilizing a machine and roughly adjusting to a designed position through a chain block; carrying out in-place mounting on a temporary connection bolt by a rotary machine; finishing correction of the steel column through a fine adjustment measure under three-dimensional space coordinate observation of a high-precision instrument; and connecting a subsequent structure in time to form a stable system. The problems that a traditional steel structure hoisting construction method is difficult to correct and the construction period is prolonged when the inclined steel column is hoisted, and relatively great hidden dangers exist in the construction safety are solved. The mounting method belongs to the technical field of construction of building steel structures.

Description

technical field [0001] The invention relates to an installation method of an inclined support steel column, which is suitable for scenes such as stadiums, and belongs to the technical field of building steel structure construction. Background technique [0002] With the rapid growth of social economy and the rapid development of the construction industry, steel structure engineering has been widely used due to its own characteristics. Moreover, after the advent of the National Stadium, modern stadiums have higher and higher requirements for structural modeling. [0003] The traditional steel column is basically vertical to the ground, its center of gravity changes in a small range, and its positioning is simple. However, in the new environment, more and more designers break the tradition and design the steel structure column at an unconventional installation angle to achieve The dual needs of green and beautiful modern buildings. [0004] When the traditional steel structur...
