Abstract

The invention discloses a secondary embedded construction method and an installation structure of a structural embedded part, wherein the method comprises the following steps of mattress layer construction; the method comprises the steps of vertically embedding first embedded bars around a region corresponding to a pre-installation position of a structural embedded part in a mattress layer, vertically embedding second embedded bars in the region corresponding to the pre-installation position of the structural embedded part, pouring a concrete mattress layer on the mattress layer, binding the structural bars on the concrete mattress layer, welding and fixing the first embedded bars and the structural bars, installing the structural embedded part in the structural bars, welding and fixing the bars at the lower end of the structural embedded part and the second embedded bars, and pouring structural reinforced concrete. According to the invention, the structural steel bars and the structural embedded parts are respectively welded with different embedded steel bars, so that the embedded steel bars can be independently fixed and bear the load born by the structural embedded parts in the construction process, and on the other hand, the bearing capacity and rigidity of the reinforcement cage in the peripheral area of the structural embedded parts are enhanced, the structural embedded parts are protected from disturbance, and the accuracy of the spatial position of the structural embedded parts is ensured.

Description

Secondary pre-embedding construction method and mounting structure for structural embedded part Technical Field The invention relates to the technical field of construction of structural embedded parts, in particular to a secondary embedded construction method and a mounting structure of a structural embedded part. Background The structure embedded part is widely applied to reinforced concrete structures and used for connecting and fixing curtain walls, awning, installation equipment and the like. At present, in the prior art, after the construction of a structural steel bar is completed, a structural embedded part is welded and fixed on the structural steel bar, and then concrete is poured, so that the structural embedded part fixed by the method is extremely easy to be disturbed to deviate from the original position in the process of structural mold sealing or concrete pouring, and the installation accuracy of the embedded part is limited. The method can meet the requirements for common curtain walls, awning and the like with low requirements on the installation accuracy of the structural embedded parts, but the method can directly influence the normal use of the structural embedded parts on the accuracy of the space positions of wagon balance and high-end informationized equipment (such as top-mounted vehicle inspection equipment, large H986 and the like), so that the requirement on the installation accuracy of the structural embedded parts is high, and the conventional technical method is difficult to realize.
