Vertical main reinforcement connection structure of prefabricated steel-concrete member and its installation method

Abstract

The invention discloses a connecting structure and a mounting method for vertical main ribs of a fabricated steel-concrete member. The connecting structure comprises an outer sleeve and two inner sleeves, and the two inner sleeves are arranged at the upper end and the lower end of the outer sleeve in a sleeved mode correspondingly; two or more outer protruding blocks are arranged on the outer wall of each inner sleeve; two or more lines of inner clamping parts are axially arranged on the inner wall of the outer sleeve at intervals, and each line of inner clamping parts is composed of two or more inner protruding blocks arranged at intervals; when the outer protruding blocks of the two inner sleeves are placed between every two adjacent lines of inner protruding blocks, and the two inner sleeves can slide in the axial direction of the outer sleeve; and when the outer protruding blocks of the two inner sleeves are clamped between each line of two corresponding adjacent inner protruding blocks correspondingly or simultaneously, arc-shaped through grooves are formed in the parts outside the space where the inner protruding blocks and the outer protruding blocks are clamped, and each arc-shaped through groove is internally provided with an arc-shaped clamping part in close fit with the arc-shaped through groove. According to the vertical main rib connecting structure and mounting method for the fabricated steel-concrete member, connecting is firm, and fabrication operation is convenient.

Description

technical field [0001] The invention relates to a prefabricated building, in particular to a vertical main reinforcement connection structure and an installation method of a prefabricated steel-concrete component. Background technique [0002] The prefabricated shear wall is generally composed of an upper wall column member and a lower wall column member, and the upper and lower wall column members are connected by vertical steel bars arranged in the upper wall column member and the lower wall column member. During production, a plurality of reserved holes are provided in the upper wall column member, and the vertical steel bars in the lower wall column member are inserted into the corresponding reserved holes, and are sealed by grouting after welding or socket fitting. The method of grouting after the sleeve connection has high requirements for the construction workers, and it is inconvenient to promote. The structural strength of the welded connection is guaranteed, but t...

AI Technical Summary

Problems solved by technology

In the above-mentioned shear wall, the upper vertical steel bar and the lower vertical steel bar are mainly connected together by screw connection, but it is easy to confuse the connecting steel bar, the upper sleeve and the lower sleeve during the assembly process, and the installation is inconvenient. At the same time, it is more troublesome to disassemble after installation error
