Embodiment Construction

[0037] Embodiment, select an industrial factory building, the structural overview is a single-layer steel structure, such as figure 1 As shown, the foundation cap 1 and the pillars are heavy-duty double-legged steel columns 2, and corbels 12 are installed above the heavy-duty double-limbed steel columns 2, and the height of the columns is 9 meters. The installation of the steel columns by the present invention requires 13 bases of the column feet The offset of the center line to the positioning axis cannot be greater than 5mm, the allowable deviation of the elevation of the column reference point is controlled within +3mm to -5mm, and the verticality of the column axis cannot be greater than H / 1000. In this case, H is 9mm.

[0038] During the construction of the foundation cap 1, in order to ensure the correctness of the elevation of the bottom of the cup-shaped foundation, the size of the cup-mouth formwork must be ensured to be accurate. The elevation of the foundation beari...

Abstract

The invention discloses a heavy battened steel column mounting construction process. The mounting construction process comprises the following steps of: A) detecting foundation dimension of a cup opening and adjusting a dimension error; B) snapping a line on the foundation and correcting elevation; C) measuring the distance from a bracket surface to the lower surface of a column bottom plate; D) lifting a heavy battened steel column; E) adjusting a column foot center line relative to a locating axis; F) adjusting the verticality of an axis of the heavy battened steel column; and G) fixing the heavy battened steel column. According to the invention, the heavy battened steel column correcting process is improved so that the working efficiency is largely enhanced and the labor intensity is reduced; and compared with the traditional correcting method, the heavy battened steel column mounting construction process disclosed by the invention has the advantages of short time in the adjusting process, capability of reducing 1 / 3 working time and engineering cost conservation.

Description

technical field [0001] The invention relates to a construction technique of a heavy-duty steel column in a steel structure engineering, in particular to a construction technique of a heavy-duty double-leg steel column suitable for a single-story steel structure factory building with a cup foundation. Background technique [0002] At present, the installation of steel components of similar steel structure workshops generally refers to the relevant regulations in the "Code for Construction Quality Acceptance of Steel Structure Engineering" GB20205-2001, to inspect the shape and geometric dimensions of steel components and foundations, to eliminate errors and to check for deviations in the installation process of steel components. control, its construction process is as follows: [0003] The detection and error adjustment of the foundation size of the cup mouth, marking the vertical and horizontal axes on the four sides of the foundation, marking the center line of the steel co...
