Problems solved by technology

The floor is an important component of the prefabricated concrete structure. At present, in the prefabricated concrete structure, the floors 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 about half less than that of the cast-in-place floor , but also large

Embodiment Construction

[0038] Such as Figure 1-Figure 12 As shown, the combined structure, manufacturing and assembly methods of the fully prefabricated floor slab and the laminated floor slab of the present invention are as follows:

[0039] 1. The structure and manufacturing method of the fully precast concrete unidirectional slab of the present invention are as follows:

[0040] Such as figure 1 As shown, the formwork of the concrete one-way slab is composed of steel formwork on opposite sides of the steel formwork and steel formwork on opposite ends of the frame. The steel formwork on opposite sides is composed of the upper steel formwork 4 and the lower steel formwork. The upper steel template 4 and the lower steel template 5 are connected into a whole by inserting the connecting steel bolt 1 into the connecting steel ring 2. The steel template on the two sides has a reserved hole 6 at the central axis; located at the end One end of the L-shaped template 3 is welded in the opposite steel template 7...

Abstract

The invention relates to the field of prefabricated assembly type concrete structure buildings, in particular to a fully-prefabricated floor and composite floor composite structure and a manufacturingand assembly method. The fully-prefabricated floor and composite floor composite structure and the manufacturing and assembly method are only suitable for the working condition that a floor is a one-way slab. The composite structure is one of the following three structures of (1) a composite structure of the fully-prefabricated concrete one-way slabs and concrete composite floors, (2) a connection structure of the fully-prefabricated floor and composite floor composite structure and a side beam, and (3) a connection structure of the-fully prefabricated floor and composite floor composite structure and a middle beam. The structures all adopt prefabricated concrete one-way slabs which are formed by pouring concrete in template structures. By changing the structures of the fully-prefabricated slab and a composite slab, then the fully-prefabricated one-way slab and the composite slab are alternately composited and assembled together to form a floor, according to the floor, compared with the composite slab, the usage amount of cast-in-place concrete is greatly reduced, and compared with the fully prefabricated slab, the better integrity is achieved.

Description

Technical field [0001] The invention relates to the field of prefabricated concrete structure buildings, in particular to a combined structure of a fully prefabricated floor slab and a laminated floor slab, and a manufacturing and assembly method. The invention is only applicable to the working condition where the floor slab is a one-way slab. Background technique [0002] Fabricated concrete structure has the advantages of fast construction speed, energy saving and environmental protection, and small amount of wet work on site. It has been developed rapidly in China in recent years. Floor slabs are an important component of prefabricated concrete structures. At present, in prefabricated concrete structures, the slabs used are generally laminated slabs, that is, semi-prefabricated and semi-casted. Although the amount of wet work for this kind of floor slab is about half less than that of cast-in-place slab , But also great. Before the laminated slab, the prefabricated concrete s...
