Joint connecting structure of prefabricated floor slab and construction method

Abstract

The invention discloses a joint connecting structure of a prefabricated floor slab and a construction method and belongs to the technical field of floor slab connection. The structure comprises a fixed plate; the fixed plate is arranged at the joint of two adjacent prefabricated floor slabs; connecting assemblies are arranged on two sides of the fixed plate correspondingly; the two adjacent prefabricated floor slabs are connected through clamping of the connecting assemblies; each connecting assembly comprises a vertical rod, a handle and a clamping module; the handles are fixedly arranged atthe top ends of the vertical rods; the bottom ends of the vertical rods penetrate through the fixed plate and then are connected with the clamping modules; clamping grooves matched with the clamping modules are formed in the prefabricated floor slabs; and the clamping modules are connected with the clamping grooves in a clamped mode. The two adjacent prefabricated floor slabs are connected together to form a whole, so that the integrity and continuity of a whole floor are guaranteed, high stability and high anti-seismic strength are achieved, and mutual dislocation between the prefabricated floor slabs is prevented.

Description

Technical field[0001]The invention belongs to the technical field of floor slab connection, and specifically relates to a node connection structure and construction method of a prefabricated floor slab.Background technique[0002]The development of residential housing to industrialization, integration and assembly is the urgent need and inevitable development direction of China's residential innovation development and structural transformation. It is also the need for the housing industry to achieve green, environmental protection and energy saving development. The assembly of residential buildings is to achieve the industrialization of residential buildings. The basis of development. To achieve the overall assembly construction of residential buildings, it is urgent to solve the problem of floor assembly.[0003]Traditional building slabs mostly use cast-in-place concrete structures, which require a large amount of formwork materials during construction, and also need to lay steel bars...

AI Technical Summary

Problems solved by technology

[0004] However, after the prefabricated floor slabs are installed, they are only connected by grouting at the joints. The connection method is not reliable, and it is difficult to effectively pull the floor slabs together. When an earthquake occurs, this connection structure is easily misplaced. Even collapse occurs, endangering people's lives and property safety
