Construction method of stiffened concrete joint overhanging type connecting piece

Abstract

The invention relates to a construction method of a stiffened concrete joint overhanging type connecting piece, and belongs to the technical field of building construction. The problem that the stiffened concrete joint collides with a steel rib during anchoring of a longitudinal bar and cannot be directly anchored in a column due to condition limitation is solved, the construction method can be used for solving the collision problem of various reinforcing steel bars and the steel rib, and reduces the site construction difficulty. The method comprises the steps that firstly, according to the elevation and arrangement of beam longitudinal bars, the connecting mode of the beam longitudinal bars and connecting pieces is determined, if sleeve connection is adopted, the number and the vertical position of sleeves are determined, according to the diameter of the beam longitudinal bars, the spacing of the sleeves and the distance between the edges of joint plates are determined, and the size of the sleeve type connecting joint plates is determined; if the welding connection is adopted, the spacing and the size of the welding type connecting joint plate are determined in the same way; then, the sizes and the number of the rest joint plates of the column steel ribs used for being connected are determined; and finally, all the sleeves and the joint plates are connected with the column steel ribs in a welded mode, and therefore construction of the stiffened concrete joint overhanging type connecting piece is completed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of an overhanging connector of a rigid concrete node. Background technique [0002] With the rapid development of urbanization, super high-rise buildings continue to emerge. The hybrid structure with steel frame and reinforced concrete cylinder as the main structural system has been widely used in super high-rise buildings. In order to meet the seismic and ductility requirements of the structure, further reduce the In the structural section, a large number of rigid steel structures are often added to the super high-rise reinforced concrete structure. Although the requirements of the structural design are well met, it also brings great difficulties to the construction of the reinforced concrete structure. In stiffened concrete joints, an obvious feature is that the longitudinal reinforcement needs to be anchored when it collides with the section...

Problems solved by technology

[0004] The purpose of the present invention is to provide a construction method for the outrigger joints of stiffened concrete joints, which solves the problem that stiffened concrete joints collide with steel frames when the longitudinal reinforcement is anchored, and cannot be directly anchored in the column due to condition restrictions. In order to deal with the collision between various steel bars and steel frames, it reduces the difficulty of on-site construction
