Prefabricated reinforced concrete beam-slab structure system with cast-in-place floors in building structures

Abstract

The invention discloses an assembled reinforced concrete beam-slab structural system with a cast-in-situ layer in a building structure. The assembled reinforced concrete beam-slab structural system comprises a superposed beam, a superposed slab, reinforcing mesh pieces, the cast-in-situ concrete superposed layer and beam negative reinforcements, wherein the superposed beam is a reinforced concrete precast beam; outwardly projecting tongue-and-grooves are formed in two sides of the upper part of the superposed beam; the superposed slab is horizontally arranged and is a reinforced concrete precast slab; cover-plate-type tongue-and-grooves are formed at the positions, corresponding to the outwardly projecting tongue-and-grooves, on two sides of the superposed slab, and overlapped on the outwardly projecting tongue-and-grooves; the reinforcing mesh pieces and the beam negative reinforcements are horizontally arranged above the superposed beam and the superposed slab; the reinforcing mesh pieces are bundled up with corresponding reinforcements in the superposed beam and the superposed slab; the beam negative reinforcements are bundled up with corresponding reinforcements in the superposed beam; after arrangement of the reinforcing mesh pieces and the beam negative reinforcements, concrete is poured to form the cast-in-situ concrete superposed layer. The assembled reinforced concrete beam-slab structural system has favorable integrity and mechanical property, and the integrity and the anti-seismic property can be improved.

Description

technical field [0001] The invention relates to a building structure, in particular to an assembled reinforced concrete beam-slab structure system with a cast-in-place layer in the building structure. Background technique [0002] Prefabricated reinforced concrete structures have already had many practical applications and relatively mature technical research in developed countries such as Europe, America and Japan. As my country has vigorously promoted the development of construction industrialization in recent years, the practical application and theoretical research of prefabricated buildings in China has continued to deepen. [0003] However, domestic research and application in this field is still in its infancy, and there is a lack of relevant norms and research guidance to support this technology. At the same time, there are major deficiencies in the construction experience, construction technology, and optimal design of prefabricated components of prefabricated rein...

Problems solved by technology

[0004] The purpose of the present invention is to provide a prefabricated reinforced concrete beam-slab structure system with a cast-in-place layer in the building structure. The shortcomings of low efficiency, poor installation accuracy, and too cumbersome on-site binding of beam longitudinal reinforcement can reduce the number of on-site supports, improve the integrity and seismic performance of the fabricated reinforced concrete beam-slab structure system, and are suitable for widespread application in building structures
