Construction method for installing stainless steel spiral stair and by adopting combined support

Abstract

The invention discloses a construction method for installing a stainless steel spiral stair and by adopting a combined support. The method comprises the following steps that (1) embedded parts are installed; (2) an inner arc line and an outer arc line are drawn on the ground; (3) a combined support system is built; (4) the spiral stair is manufactured into stair sections; (5) all the stair sections are lifted in place in sequence, the lower ends of the next stair sections are fixed to the upper ends of the last stair sections in a spot welding mode; (6) two sight line theodolites are adopted to track and correct installation of the stair sections; and (7) welding joints between every two adjacent stair sections are fixed in an integral welding mode, and then all support bodies are dismounted. According to the construction method for installing the stainless steel spiral stair and by adopting the combined support, the problem that a spiral stair does not have supports in the installing process is solved, installing is convenient, construction efficiency is higher, stability in the installing process is good, and installing precision is also high.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for installing a stainless steel spiral staircase with a combined bracket. Background technique [0002] Spiral staircase is usually called spiral or spiral staircase. Because of its beautiful, elegant and elegant streamlined shape, it saves space. It is often used in office buildings and residential buildings with few floors, or as architectural sketches in courtyards or indoors. The spiral staircase is usually arranged around a single column, and the plane is circular. This kind of staircase includes an inner annular edge beam, an outer annular edge beam and several treads arranged between the inner annular edge beam and the outer annular edge beam , Such a staircase has a large section and can carry a large flow of people. However, since there is no support column in the middle of the spiral staircase, it is difficult to construct during th...

AI Technical Summary

Problems solved by technology

However, since there is no supporting column in the middle of the spiral staircase, it is difficult to construct during the construction process, and it needs to be supported by a support, which is not only inconvenient for construction, but also low in construction efficiency; moreover, the stability of the spiral staircase during installation is low, and the installation accuracy is also low.
