Deformable connection structure of concrete roof and metal plate roof

Abstract

The invention discloses a deformable connection structure of a concrete roof and a metal plate roof. A certain gap is reserved between the concrete roof and the metal plate roof, and an iron sheet (8) is mounted at the lower end of a connection position of a beam (1) of the concrete roof and a keel (7) of the metal plate roof; a heat insulation material (3) and a metal sandwich plate (5) are laid on a concrete plate and the roof keel (7), wherein a joint is reserved between the heat insulation material (3) and the metal sandwich plate (5) and filled with a certain filling material (9); a steel plate (4) is taken as a flashing material, stretches across the beam (1) of the concrete roof and the keel (7) of the metal plate roof, and is located above the heat insulation material (3) and the metal sandwich plate (5); and two ends of the steel plate (4) are sealed respectively with a sealing material, so that water is prevented from entering. The deformable connection structure can meet requirements for deformation joints in a large-scale project, has the functions of sedimentation, shock-proofing and expansion at the same time, and improves the drainage performance.

Description

technical field [0001] The invention relates to a wall connection structure, in particular to a deformable connection structure between a concrete roof and a metal plate roof. Background technique [0002] In the field of construction, it is often possible to encounter situations where walls need to be joined. In particular, multiple walls of different materials need to be connected to each other and meet certain requirements for strength, waterproof, and flame resistance. For example, the connection methods of doors, windows and walls mainly include steel attached frame connection, dovetail iron foot welding connection, dovetail iron foot and embedded parts connection, fixed steel sheet nailing connection, fixed steel sheet metal expansion bolt connection, etc. The connection between the doors and windows and the reinforced concrete wall can be connected by fixing steel sheets (or dovetail iron feet) with nails or metal expansion bolts. When the fixed steel sheet is used ...

AI Technical Summary

Problems solved by technology

The original connection structure cannot meet the treatment of deformation joints, the joint width in a large scale range, and the current requirements for building settlement, earthquake resistance and expansion.
