Rib type brackets and method for constructing top way steel pipe support and top plate through brackets

Abstract

The invention discloses rib type brackets and a method for constructing a top way steel pipe support and a top plate through brackets. Each bracket comprises an anchoring steel rib (1), a U-shaped supporting rib and an embedded steel plate (3), wherein an anchoring vertical rib body (1) and an anchoring inclined rib body (1.2) of the anchoring steel rib (1) are located in a capping beam (4), and a vertical section (2.1) of the U-shaped supporting rib is fixed to the lower end of the anchoring steel rib (1). The method is characterized in that the two ends of the top way steel pipe support (5) are placed on the two rib type brackets, and the top way steel pipe support (5) is welded and fixed to embedded steel plate (3) of the rib type brackets. According to the brackets and the method, connection between ribs of the basement top plate (9) and a guard post wall (6) is not blocked, and the requirement for placement of the top way steel pipe support (5) can also be met.

Description

technical field [0001] The invention relates to foundation pit construction technology in the field of civil engineering, in particular to a tendon-type bracket used to connect the top steel pipe support and the surrounding protective pile wall of the foundation pit when the top steel pipe support needs to be embedded in the concrete roof of the basement , and a method for using the rib type bracket to install the top steel pipe support of the foundation pit and construct the basement roof. Background technique [0002] With the extensive rise of subway engineering and underground space engineering construction, the construction technology of foundation pit and basement structure is also developing continuously. The traditional construction method of the foundation pit and basement structure is to construct the retaining pile wall first, then pour the cap beam on the retaining pile wall, then fix the roof steel pipe support at the same level as the cap beam, and then start d...

AI Technical Summary

Problems solved by technology

[0003] First, analyze the connection mode between the top steel pipe support and the two pressure beams at both ends. The steel corbels are first fixed on the top beam, and the two ends of each top steel pipe support are placed on the two steel corbels first, and then connected with The two roof beams at both ends of the support are welded and fixed. The steel corbels are large in size. If the basement roof is directly constructed without removing the steel corbels, the steel bars of the basement roof will be blocked by the steel corbels and cannot be connected to the roof beams and the surrounding pile walls. fixed; while the installation and removal of steel corbels will result in reduced construction efficiency and increased costs
