Description

Insulation and decoration composite wall integrated with decorative panel and formwork and its construction method

technical field

The invention relates to the technical field of composite walls, in particular to a thermal insulation and decorative composite wall integrated with a decorative panel and a formwork and a construction method thereof.

Background technique

The cast-in-place lightweight composite wall usually uses a light steel keel as the skeleton, and installs calcium silicate boards and other non-dismantling panels on both sides of the skeleton by screws, and pours lightweight materials such as foam concrete in the cavity, and forms a composite wall after hardening body. This kind of wall has the advantages of light weight, good seismic performance, and no plastering, etc. It is widely used in the inner partition wall of high-rise frame structure buildings, as well as the inner and outer walls of low-rise buildings. When it is used on the exterior wall, it needs to be decorated on the outside of the wall, and in some areas, an insulation layer and a decorative layer should be made on the outside of the wall. The non-demolition panel is usually made of asbestos-free ordinary calcium silicate board or asbestos-free fiber cement plane, and is fixed to the light steel keel by self-tapping screws. The nail hole part of the panel is easy to crack due to panel deformation.

Chinese patent 201610445865.8 "Dry-hanging composite thermal insulation decorative wall panel and dry-hanging thermal insulation component of building wall" discloses a thermal insulation and decorative composite wall panel. Although no screws are used, the decorative sheet is directly fixed on the glass magnesium sheet lining. The fixing device will directly cause the decorative sheet to be unstable and easy to fall off. Chinese patent 201610030513.6 "A new type of thermal insulation and decorative wall and its construction method" discloses a fixed thermal insulation structure through a bayonet plate structure. Four or more insulation board structures are fixed on the frame around the structure, and the middle part is only through the bayonet plate structure. If it is fixed, it will lead to uneven force in the middle of the insulation board and easy to collapse, and its function is too single, and its bending rigidity is weak. Chinese patent 201620707210.9 "A H-shaped clip connector for teaching aids" belongs to the technical field of teaching aids model building, and has nothing to do with the technical field of composite walls to which the present invention belongs, and there is no technical inspiration.
