Concealed beam type connecting fully-prefabricated concrete plate structure and manufacturing and assembling methods

Abstract

The invention relates to the field of prefabricated assembly type concrete structure buildings, in particular to a concealed beam type connecting fully-prefabricated concrete plate structure and manufacturing and assembling methods. Fully-prefabricated concrete plates are formed in the mode that concrete is poured into formwork structures; longitudinal steel bars and transverse steel bars are arranged in the fully-prefabricated concrete plates horizontally and are each of the structure with the two ends being bent on the inner side of the corresponding fully-prefabricated concrete plate; and vertical sections between the bottom edges of the longitudinal steel bars and the transverse steel bars and the bent sections of the longitudinal steel bars and the transverse steel bars are arranged on the outer sides of the fully-prefabricated concrete plates. According to the concealed beam type connecting fully-prefabricated concrete plate structure, concealed beam longitudinal steel bars penetrate through closed hoops formed by lap joint of the exposed steel bars of the two prefabricated concrete plates, then, concrete is poured, and thus the plates are connected; the concealed beam longitudinal steel bars penetrate through the closed hoops formed by lap joint of in-beam reserved connecting steel bars and the exposed steel bars of the prefabricated concrete plates, then, the concrete is poured, and thus fixing of the plates on beams is completed; and the requirement for plate and beam connection in actual engineering is completely met.

Description

technical field [0001] The invention relates to the field of prefabricated and assembled concrete structure buildings, in particular to a hidden beam-type connected full prefabricated concrete slab structure, a manufacturing and assembling method. Background technique [0002] In recent years, with the development of the national economy and the adjustment and transformation of the economic structure, the original building system is difficult to adapt to the track of rapid economic development, nor can it be well suited to the new architectural structure, and cannot satisfy customers well. Therefore, countries with prefabricated building systems have begun to guide and promote a large number of policies. The prefabricated concrete structure has the advantages of fast construction speed, energy saving and environmental protection, and small amount of wet work on site. It has developed rapidly in China in recent years. The floor is an important component of the prefabricated ...

AI Technical Summary

Problems solved by technology

[0003] At present, in prefabricated concrete structures, the floor slabs used are generally laminated slabs, that is, semi-prefabricated and semi-cast-in-place. Although the wet work volume of this kind of floor is less than that of cast-in-place floors, it is still very large.
