Improved hidden beam type connection full-prefabricated slab structure and manufacturing and assembling method

Abstract

The invention relates to the field of prefabricated concrete structure buildings, in particular to an improved hidden beam type connection full-prefabricated slab structure and a manufacturing and assembling method thereof. Transverse stress ribs and longitudinal stress ribs are horizontally distributed in a full-prefabricated slab in a crossed mode, the two ends of the transverse stress ribs andthe longitudinal stress ribs are bent into the structures at the inner side of the full-prefabricated slab, and vertical sections between the bottom edges and the bent sections of the longitudinal stress ribs and the transverse stress ribs are exposed out of the full-prefabricated slab; the exposed portions of the longitudinal stress ribs at the corresponding positions of the two full-prefabricated slabs are in tight staggered overlapping to form a closed hoop, angle iron with a hook penetrates through the closed hoop and is hooked to the closed hoop through the hook, and the angle iron and the closed hoop are bound; expanded concrete is poured at the joint of the two full-prefabricated slabs, and connection between the two full-prefabricated slabs is completed. Compared with an assembledconcrete composite floor slabs and cast-in-place concrete floor slabs, the wet operation amount is greatly lowered, on-site splicing is easier, the construction quality is more easily ensured, and thestructure is applicable to the large slab span.

Description

technical field [0001] The invention relates to the field of prefabricated concrete structure buildings, in particular to an improved concealed beam-type connected full prefabricated panel structure, a manufacturing and assembling method. Background technique [0002] The prefabricated concrete structure has the advantages of fast construction speed, energy saving and environmental protection, and small amount of wet work on site. In recent years, with the development of the national economy and the adjustment and transformation of the economic structure, the prefabricated building system has been guided and promoted by a large number of national policies. The floor is assembled An important component of concrete structures. At present, in the prefabricated concrete structure, the floor slabs used are generally laminated slabs, that is, semi-prefabricated and semi-cast-in-place. The wet work volume of this kind of floor is still relatively large. Before the laminated slab, ...

Problems solved by technology

For this reason, in the previous invention of the inventor, he invented "concealed beam type connection full prefabricated panel structure, manufacturing and assembly method (authorized announcement number CN207660171U)". The sides are smooth and the shear resistance is weak, so it is not suitable for large-span floors with large loads, and because the longitudinal reinforcement needs to be bound, the assembly speed is slow
