Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] When connecting the concrete roof and the metal plate roof, the following steps can be used.

[0024] a. There is a certain gap between the concrete roof and the metal plate roof. The roof keel 7 is aligned with the beam 1 of the concrete roof. First, the iron sheet 8 is installed on the connection between the beam 1 of the concrete roof and the roof keel 7 of the metal plate roof. At the lower end, as a plug, the iron sheet is fixed on the side of the concrete beam close to the deformation joint with steel nails 2, and the iron sheet 8 is fixed on the lower end surface of the roof keel 7 of the metal plate roof with rivets, wherein the iron sheet 8 is in the deformation joint. The length is greater than the length of the deformation joint, that is, the iron sheet 8 has a certain surplus;

[0025] b. Lay the thermal insulation material 3 and the metal sandwich panel...

Abstract

The invention relates to a deformable connection method and 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 sheet iron (1) is mounted at the lower end of a connection position of a beam (1) of the concrete roof and a roof keel (7) of the metal plate roof; a heat insulating material (3) and a metal core board (5) are laid on a concrete slab and the roof keel; a seam is reserved between the heat insulating material (3) and the metal core board (5); the seam is filled with a certain filler material (9); a steel plate (4) is taken as a flashing material and stretches across the beam (1) of the concrete roof and the roof keel (7) of the metal plate roof and located above the heat insulating material (3) and the metal core board (5); and two ends of the steel plate (4) are sealed by a sealing material, so that water is prevented. According to the deformable connection method and the deformable connection structure of the concrete roof and the metal plate roof, requirements for a deformation seam in a large-scale project can be met, sedimentation, shock proofing, stretching effects are realized at the same time, and the drainage performance is improved.

Description

technical field [0001] The invention relates to a wall connection method and a connection structure, in particular to a deformable connection method and 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 ...
