Embodiment Construction

[0031] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and implementation methods.

[0032] Such as figure 1 , 2 As shown, a prefabricated building bottom composite floor, including independent foundation (1), square head short column (2), main beam (3), maintenance plate (4), secondary beam (5), profiled steel plate (6 ), steel mesh (7), surface layer (8), decorative layer (9), horizontal fastener (10), and pull rivet (11).

[0033] refer to figure 2, the independent foundation (1) is a reinforced concrete foundation prefabricated in the factory to determine its size according to the self-weight of the superstructure, and the independent foundation (1) includes concrete piers (101), foundation short columns (102), and foundation end plates (103); The pier (101) determines its cross-sectional area, reinforcement, and height according to the self-weight of the upper structure and the soi...

Abstract

Provided are an assembly-type building bottom-layer composite floor and a connection mode thereof. Factory-fabricated reinforced concrete with embedded parts is used as independent basis, square headshort columns are factory-prefabricated connection components and connected with upper chord members and lower chord members of main beams through pulling rivets to form outer frames of floors; on thebasis of the outer frames, secondary beams, profiled steel sheets and reinforcing meshes are laid horizontally, a surface course is poured, a decorative layer is attached to the surface course, and thus a mortise and tenon joint type connection mode of the floors and basic nodes is formed by combing insertion, pulling rivet connection and flange connection. According to the assembly-type buildingbottom-layer composite floor and the connection mode, the building mode of a traditional bottom-layer floor can be changed, the assembly type can be achieved, and the defects of poor vibration performance and soundproof effect and the like of an assembly-type light steel composite floor can also be overcome; meanwhile, the assembly-type building bottom-layer composite floor also has the advantages that the floor is assembled rapidly and subjected to industrial production easily and is high in strength and high in production speed, and has large actual project significance and market values topromotion and development of assembly-type buildings.

Description

technical field [0001] The invention relates to a composite floor slab at the ground floor of a prefabricated building and a connection method thereof, belonging to the technical field of prefabricated construction engineering. Background technique [0002] In the construction process of light steel prefabricated buildings, the assembly of floor slabs is an important link, and it is also the most difficult process of assembly. Especially for the construction and treatment of the ground floor of light steel prefabricated buildings, due to the need to meet performance requirements such as firmness and durability, reducing heat absorption, etc., it also needs to meet structural requirements such as sound insulation, waterproof, moisture-proof, heat insulation, and no cracks , At present, it is still necessary to use on-site wet work to construct and process the decorative layer, surface layer, bonding layer, filling layer, isolation layer, and floor slab. However, the construc...
