Embodiment 1

[0052] A method for installing a suspension column for large-scale suspended steel structure construction, such as Figure 1-6 As shown, the above-mentioned hanging columns are divided into three-section installation, and the number of floors where the steel beams on the first floor of the above-ground structure are located is set as X floor, the first section of hanging columns is installed on the X~X+1 floor, and the second section of hanging columns is installed on X +1~X+4 floors, the third section of the suspension column is installed on the X+4~X+6 floor; the first section of the suspension column installation and positioning axis of the X~X+1 floor takes the top hanging point as the reference point; The structure system of the hanging column and the steel beam includes a steel bar truss 1, an inner hanging column main body 6 and an outer hanging column main body 4, and the inner hanging column main body 6 is installed on the inner side of the steel bar truss 1 through an...

Embodiment 2

[0078] A method for installing a suspension column for large-scale suspended steel structure construction, such as Figure 1-6 As shown, in order to improve the reliability of the connection between the two suspenders; this embodiment makes the following improvements on the basis of Embodiment 1: the top outer walls of the outer suspender main body 4 and the inner suspender main body 6 are provided with positioning micro Groove 18, the outer wall of the bottom of the outer hanging column main body 4 and the inner hanging column main body 6 is uniformly provided with positioning protrusions 17, and the positioning protrusions 17 are adapted to the positioning micro-grooves 18; by setting the positioning protrusions 17 and positioning micro-grooves The groove 18 can facilitate auxiliary positioning between the two outer davit main bodies 4 or two inner davit main bodies 6 when connecting and fixing them, thereby improving construction accuracy and reliability.

Abstract

The invention discloses a davit mounting method for construction of a large suspension type steel structure construction, and relates to the technical field of suspension type steel structure construction. In order to improve the installation effect and guarantee the reliability of the structure, a davit and steel beam structure system specifically comprises a steel bar truss, an inner davit body and an outer davit body, the inner davit body is installed on the inner side of the steel bar truss through an inner davit connecting mechanism, and the outer davit body is installed on the outer side of the steel bar truss through an outer davit connecting mechanism. A hanging structure system is adopted, steel beams between floors are connected through davits, in order to reduce installation errors and reduce segmentation of the davits as much as possible, the davits are installed in three sections, the first davit section is installed on the (X-X + 1) floor, the second davit section is installed on the (X + 1) floor to the (X + 4) floor, and the third davit section is installed on the (X + 4) floor to the (X + 6) floor; a top hanging point is used as a reference point for a mounting and positioning axis of the first davit section of the (X-X + 1) layer; the construction error is reduced, and the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of suspended steel structure construction, in particular to a method for installing a suspension column for large-scale suspended steel structure construction. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts rust removal and antirust processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, venues, super high-rises and other fields; in the construction of large suspended steel structures, it is often necessary to use davits for load transmission; the current davi...
