Method for installing post-installed steel beam of basement roof frame

Abstract

The invention discloses a method for installing a post-installed steel beam of a basement roof frame, and belongs to the technical field of installation of a post-installed steel beam of a basement roof frame. The method comprises the steps of drilling an 80mm round hole (3) in a concrete roof (2) in the middle position of a pre-installed steel beam (1) of a basement (4), and placing a tooling hanger (5) right above the concrete roof (2) and the round hole (3); fixing a chain hoist cable tool (6) on the tooling hanger (5) to vertically pass through the 80mm round hole (3) of the concrete roof,and fixing a to-be-installed steel beam (8) at a lower portion of the basement (4) by a cable tool (7); pulling and lifting the steel beam (8) by the chain hoist cable tool (7) on the tooling hanger(5) for installation in place. The method has the advantages that the operation is easy, the concrete roof is prevented from being removed, the installation period is shortened, the installation quality is ensured, the installation cost is greatly reduced, and good economic benefits are obtained.

Description

technical field [0001] The invention belongs to the technical field of installing a rear steel beam of a basement roof frame, and in particular provides a method for installing a rear steel beam of a basement roof frame. Background technique [0002] A multi-storey steel frame structure building with a basement, due to the addition of some equipment on the first floor in the later period, [0003] The force on the roof of the basement increases. After the design calculation, it is necessary to add steel beams to the roof frame of the basement to strengthen the force on the roof. The main difficulty in the installation of the rear steel beams is that the concrete roof of the basement frame has been formed, and the normal installation of the steel beams generally needs to be chiseled out. After the steel girder concrete roof is installed from above, the amount of chiseling is very large, such as chiseling the concrete roof and so on. Contents of the invention [0004] The p...

[0003] The force on the roof of the basement increases. After the design calculation, it is necessary to add steel beams to the roof frame of the basement to strengthen the force on the roof. The main difficulty in installing the rear steel beams is that the concrete roof of the basement frame has been formed, and the normal installation of the steel beams generally needs to be chiseled out. After the steel beam concrete roof is installed from above, the amount of chiseling is very large, such as chiseling the concrete roof, etc.
