Ribbed aerated concrete tongue-and-groove floor system and assembly method thereof

Abstract

The invention provides a ribbed aerated concrete tongue-and-groove floor system which is formed by prefabricated aerated concrete tongue-and-groove plates (1), longitudinal ribs (2), bolt connection pieces (3) and a steel support (4). Bottom surfaces of the tongue-and-groove plate (1) are closely attached to the upper surfaces of the longitudinal ribs (2), the lengths of the prefabricated aeratedconcrete tongue-and-groove plates and the longitudinal ribs are the same, the prefabricated aerated concrete tongue-and-groove plates and the longitudinal ribs are combined to form a floor whole bodythrough the bolt connection pieces (3) which are coated by rubber gaskets (33), the longitudinal ribs (2) of the floor is placed on the steel support (4), the steel support (4) is fixed on a bearing wall (5), and an assembly system is formed. An aerated concrete floor has the defects of low bending rigidity and insufficient spanning ability, the assembly of a floor tongue-and-groove position in ahorizontal direction is inconvenient, the combination of two materials is easy to generate temperature stress and the like, the above defects are solved by the ribbed aerated concrete tongue-and-groove floor system, and the system has the advantages of light weight, good shock resistance performance and high industrial production degree, high degree of assembly, non-wetting operation, detachable recycling and can be applied to the field of civil engineering.

Description

technical field [0001] The invention relates to an assembled structure, in particular to a ribbed aerated concrete tongue-and-groove floor system and an assembly method, belonging to the field of civil engineering structures. Background technique [0002] Prefabricated buildings use industrialized production and assembled construction, which has the advantages of high production efficiency, low cost, and stable quality. Aerated concrete and glued bamboo and wood materials are industrially produced products. Aerated concrete has low price, green environmental protection, and light weight. , heat insulation, sound insulation, fire resistance, impermeability, earthquake resistance, etc., but its tensile and bending properties are poor, and it is mostly used for wall panels and small-span floor slabs. Glued bamboo and wood materials use bamboo or wood as raw materials. As a new generation of green and environmentally friendly materials, it has the advantages of fast-growing and ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a ribbed aerated concrete floor system with grooves and grooves, which overcomes the shortcomings of the existing aerated concrete floor slabs, such as insufficient bending stiffness, insufficient spanning capacity, and low strength utilization rate, through the combination of various materials. Hinges are designed on the support to overcome the difficulty of connecting ribbed tongue-and-groove slabs horizontally, and rubber gaskets are designed on the surface of the bolts to overcome the problem of temperature stress caused by different linear expansion coefficients between different materials, and at the same time improve the impact resistance under dynamic loads Performance and anti-seismic performance, through the design of embedding the bolt surface into concrete to realize the flat surface of the floor slab, it has the comprehensive advantages of light weight, good earthquake resistance, high degree of industrial production, high degree of assembly, no wet operation, detachable and reusable, suitable for construction Slabs for structures and temporary installations
