Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] see Figure 1-8 , the present invention provides a technical solution: an assembled integral subway station structure with annular steel bars overlapping, including a cast-in-place floor 1, the left and right sides of the cast-in-place floor 1 are symmetrically arranged with prefabricated side walls 2, and the top of the cast-in-place floor 1 is provided. A prefabricated double-layer integrated central column 3 is arranged on t...

Abstract

The assembled integral subway station structure comprises a cast-in-place bottom plate, prefabricated side walls are symmetrically arranged on the left side and the right side of the cast-in-place bottom plate, and prefabricated double-layer integrated middle columns are arranged on the front side and the rear side of the top of the cast-in-place bottom plate correspondingly; a superimposed top longitudinal beam is arranged between the tops of the two prefabricated double-layer integrated middle columns, and a prefabricated middle longitudinal beam is arranged between the middles of the two prefabricated double-layer integrated middle columns. According to the assembled integral subway station structure with the annular reinforcing steel bars in lap joint, the prefabricated slabs are in lap joint rapidly through the reinforcing steel bar connectors and the reinforcing steel bar buckles, the lap joint length of the reinforcing steel bars is reduced, efficiency is high, mold-free and support-free effects are achieved, the number of field operation workers is reduced, component production factorization and installation mechanization are achieved, civilized construction and environmental protection are facilitated, and the construction period is shortened. The structure integrity is good, construction is convenient, the engineering quality is improved, the construction period is shortened, green development of rail transit is assisted, and green intelligent construction is achieved.

Description

technical field [0001] The invention relates to the technical field of prefabricated stations, in particular to a prefabricated integral subway station structure in which annular steel bars are overlapped. Background technique [0002] At present, my country's urban underground engineering has entered a period of rapid development. In the construction of cast-in-place concrete structures, most of the work is done by manual labor, from scaffolding, formwork, tying steel bars to concrete pouring. There are many construction personnel, manual labor, high labor intensity, and high proficiency requirements; the construction speed is slow, the construction period is long, and it is greatly affected by natural conditions; the appearance and internal quality of concrete are difficult to control, the structure is poor in waterproofness, and the degree of mechanization is not high. higher issues. [0003] At the same time, when the prefabricated components are connected by post-cast co...
