Embodiment

[0078] refer to Figure 1-5 , a half-upside-down construction method for a split-story steel structure building, comprising the steps of:

[0079] 1. Technical preparation

[0080] (1) Deepen the construction drawings from top to bottom, calculate the construction load and simulate unloading stress distribution changes, and the deepened drawings have been reviewed and approved by the design institute, and have passed the review of the drawing review agency.

[0081] (2) Compile the upward-downward and reverse-up construction plan, which shall be reviewed and approved by the design unit, supervision unit, and construction unit, and passed through expert demonstration.

[0082] (3) Calculate the installation height of the lattice column and process it in advance.

[0083] 2. Installation of traffic body support

[0084] Embedded parts installation. The steel column horse stool is buried in the raft foundation, the height of the horse stool = the thickness of the raft - the h...

Abstract

The invention discloses a half-reverse construction method for a split-level steel structure building, relates to the technical field of building construction. The invention aims to solve the problems that the capping speed of a building main body is delayed and the time for occupying a next-step area is increased in a traditional sequential construction method. According to the half-reverse construction method, a reverse construction method is adopted for construction of a large cantilever staggered floor structure on the lower portion of a traffic body, the hoisting problem in a narrow space is solved, the measure investment is reduced, the occupied time for locating a next area is shortened, and therefore the efficiency of staggered rigid floor building construction is improved; in addition, a convenient positioning structure is adopted in the mounting process of a latticed column, a supporting column body is inserted into a clamping groove through a connecting plate, in the downward moving process of the connecting plate, a spring is extruded firstly, and when a limiting column moves to correspond to the position of a limiting groove, the limiting column can automatically enter the limiting groove to preliminarily limit a supporting column, and follow-up personnel can conveniently assemble the supporting column.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a half-upside-down construction method for a split-story steel structure building. Background technique [0002] The staggered-story steel structure building adopts the traditional sequential construction, and the construction is carried out layer by layer. On the staggered building layer, the main body of the building and the staggered structure are constructed at the same time. [0003] However, this architectural model will delay the topping 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 in the site or the development of the construction surface of the site. Based on this, the present invention designs a semi-reversed construction method for a split-story stee...
