Abstract

The invention discloses a semi-reversed construction method for a staggered-story steel structure building. The invention relates to the technical field of building construction and is used to solve the problems of delaying the topping speed of the main body of the building and increasing the time occupied by the next step area in the traditional forward construction method. The present invention adopts reverse construction method in the overhanging staggered-floor structure at the lower part of the traffic body, which solves the problem of hoisting in a narrow space, reduces the investment in measures, shortens the time taken for the positioning of the next step area, and thus increases the construction efficiency of the staggered rigid-floor building , In addition, the present invention adopts a convenient and convenient positioning structure in the process of installing the lattice column, so that the support column body is inserted into the slot through the connecting plate, and the spring is first squeezed into shape during the downward movement of the connecting plate. When the limiting column moves to correspond to the position of the limiting groove, the limiting column can be automatically entered into the limiting groove to initially limit the supporting column, which is convenient for subsequent personnel to assemble.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a semi-reverse construction method for a split-level steel structure building. Background technique [0002] The split-level steel structure building adopts the traditional smooth construction, which is constructed layer by layer. On the split-level building layer, the main building and the split-level structure are constructed at the same time. [0003] However, this construction mode will delay the capping progress of the main body of the building and delay the time when the building is put into use. If the main body of the building is a horizontal through structure, it will greatly prolong the occupation time of the lower area, affecting the road traffic of the site or the expansion of the construction surface of the site. Based on this, the present invention designs a semi-reverse construction method for a split-level steel structure building. SUMMARY OF THE I...
