Connecting method of non-supporting-type composite floor slab and PEC shear wall

Abstract

The invention relates to a connecting method of a non-supporting-type composite floor slab and a PEC shear wall and belongs to the technical field of specially-designed floor slab structures of commonbuilding constructions. The floor slab and the PEC shear wall are connected through a plurality of connecting pieces; the PEC shear wall is composed of a steel skeleton and an externally filling concrete body; and the connecting pieces are fixed to the PEC shear wall, and support negative reinforcements are fixed to the connecting pieces and extend into the floor slab, and the intervals between the adjacent connecting pieces are equal to those between the support negative reinforcements. The connecting method is applied to processing of the long and short span steel truss concrete composite floor slab and has the advantages of high bearing capability, high connecting firmness and the like.

Description

technical field [0001] The application relates to a connection method between an unsupported laminated floor slab and a PEC shear wall, and belongs to the technical field of specially designed floor slab structures for general building structures. Background technique [0002] Concrete structures, especially residential building structures, require flexible layout and structural integrity. In order to meet the requirements of structural integrity, the relevant codes and designs of concrete structures usually cast in-situ the joints between the floor slab and concrete beams and columns, which is widely accepted. For the multi-story prefabricated concrete shear wall structure, the relevant method is also used, but it is obviously not applicable to the steel structure shear wall. [0003] The construction speed of the prefabricated steel structure is fast and the assembly rate is high. Because the floor slab and the steel structure shear wall cannot arrange a large number of c...

Relevant practices are also used for multi-story prefabricated concrete shear wall structures, but it is obviously not applicable to steel structure shear walls

[0003] The construction speed of the prefabricated steel structure is fast, and the assembly rate is high. Because the floor slab and the steel structure shear wall cannot arrange a large number of connecting steel bars to meet the traditional node connection requirements, it severely limits the application of the prefabricated steel structure residential system.

The PEC shear wall is composed of a steel skeleton connected by a plurality of T-shaped steels and external filling concrete. If the steel web does not have a large number of holes to penetrate the steel bars, it cannot be achieved with the floor through cast-in-place concrete. Integrity requirements; and the traditional perforation and reinforcement not only weakens the steel plate, but also makes it difficult to penetrate the reinforcement

[0004] However, there is no relevant research on the connection joint structure between the unsupported steel truss laminated floor and the PEC shear wall
