Fiber sheet concrete bidirectional laminated slab close-splicing connection structure and implementation method

Abstract

The invention provides a fiber sheet concrete bidirectional laminated slab close-splicing connection structure and an implementation method. The fiber sheet concrete bidirectional laminated slab close-splicing connection structure comprises a strip-shaped fiber sheet, prefabricated concrete bottom plates, a post-pouring concrete laminated layer, plate bottom longitudinal force bearing bars and a laminated surface additional bar, wherein the strip-shaped fiber sheet is connected to a slab joint between two spliced prefabricated concrete bottom plates and is located on the lower surfaces of theprefabricated concrete bottom plates; the plate bottom longitudinal force bearing bars are provided with bended end parts and the bended end parts are anchored into the post-pouring concrete laminatedlayer; and the laminated surface additional bar is arranged on the upper surfaces of the prefabricated concrete bottom plates and stretches across the slab joint, and is connected with the bended endparts of the plate bottom longitudinal force bearing bars. According to the fiber sheet concrete bidirectional laminated slab close-splicing connection structure and the implementation method, the strip-shaped fiber sheet is bonded to the lower surface of the slab joint between the prefabricated concrete bottom plates, the tensile stress on the section of the slab joint can be complementally borne, the section bearing capacity can be effectively improved, and thus the integrality of a floor system can be improved.

Description

technical field [0001] The invention relates to an assembled construction technology of concrete structural components, in particular to a close-fitting connection structure of fiber sheet concrete two-way laminated slabs and an implementation method. Background technique [0002] The modernization of the construction industry is the general direction of the development of the construction industry. Vigorously developing prefabricated buildings is an important measure for my country to promote the industrialization of construction and promote the transformation and upgrading of the construction industry. Compared with the all-cast-in-place structure, the prefabricated structure can greatly shorten the construction period, reduce labor force, and reduce environmental pollution. In the prefabricated concrete structure, the floor is the part that is most likely to be prefabricated. Composite floors have been widely used in prefabricated concrete structures currently being prom...
