Assembly type prefabricated part connecting structure and construction method thereof

Abstract

The invention relates to the technical field of buildings, and discloses an assembly type prefabricated part connecting structure. The structure comprises a first prefabricated stand column, wherein first axial steel bars are fixedly installed in the first prefabricated stand column, the outer walls of the first axial steel bars are sleeved with first radial steel bars, the first radial steel barsare fixedly connected with the first axial steel bars through first binding wires correspondingly, a first positioning groove is formed in the top of the first prefabricated stand column, and a firstreserved pouring cavity is formed in the position, located on the right side of the first positioning groove, of the top of the first prefabricated stand column. According to the assembly type prefabricated part connecting structure and a construction method thereof, air is prevented from making contact with a first connecting sleeve and a second connecting sleeve through concrete cast-in-place,the situation that the prefabricated part connecting structure is corroded due to the fact that the prefabricated part connecting structure is exposed in the air is avoided, and the installability andstability of the prefabricated part connecting structure are further improved, so that the assembly type prefabricated part connecting structure is convenient to popularize.

Description

technical field [0001] The invention relates to the field of construction technology, in particular to an assembled prefabricated component connection structure and a construction method thereof. Background technique [0002] Office buildings, residential buildings and industrial building slab structures have the largest construction workload, and there are two ways to construct slab structures. One way is in-situ pouring. In-situ pouring has good overall structure, strong earthquake resistance, and no water seepage , Another method of floor construction is factory prefabrication, transported to the site for installation, saving materials, guaranteed quality, fast construction speed, less on-site wet work, and good construction environmental protection, which is favored. [0003] The disadvantages of traditional cast-in-place slab construction are: cast-in-place slabs require on-site formwork and on-site pouring, which not only requires a large workload, but also takes a lon...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an assembled prefabricated component connection structure and its construction method, which has the advantages of high safety performance and solves the shortcomings of the traditional floor structure construction site casting: the cast-in-place floor requires on-site formwork, On-site pouring not only requires a lot of work, but also takes a long time for the formwork. The formwork needs to be removed after the concrete hardens. And the waste of auxiliary materials is large, the cost of the actual floor is much higher than that of the prefabricated floor, and the disadvantage of factory prefabrication is: the steel bars exposed at the end of the prefabricated slab are set in the form of threads on the outer wall, and the two prefabricated slabs are connected by a connecting sleeve with internal threads. The exposed steel bars are connected to each other, the connection method is single, the stability is poor, and it is easily corroded when exposed to the air, which causes problems such as low safety of the building floor structure
