Abstract

The invention provides an exterior wall of a prefabricated building, which includes a thermal insulation board, a cover layer, an L-shaped embedded part and a cement layer. For all the panels except the inner panels, the L-shaped embedded parts include intersecting inner arms and outer arms. The length of the outer arms is greater than the thickness of the insulation board. On the wall, the end connecting the inner arm faces the cement layer inside the insulation board, the free end of the inner arm is inserted into the cement layer, and the insulation board, cover layer, L-shaped embedded part and cement are connected through the connecting piece pierced by the L-shaped embedded part. Layers are connected as one. The insulation board includes 100 parts of inorganic fiber and 1-13 parts of phenolic resin. The prefabricated building exterior wall in the present invention, through a reasonable structural layout, makes the structure of the prefabricated exterior wall simple, the exterior wall processing is convenient, combined with the new thermal insulation material, the fire prevention, isolation and mechanical properties are greatly improved.

Description

technical field

[0001] The invention belongs to the field of new prefabricated buildings, in particular to an exterior wall of a prefabricated building. Background technique

[0002] In recent years, with the development and promotion of prefabricated buildings in China, the external thermal insulation system of thermal insulation and decorative wall panels, as a wall thermal insulation technology, has a factory-like prefabricated anti-beating bonding process, which can ensure controllable quality and reduce construction costs. Difficulty, cycle saving, and beautiful "curtain wall" effect.

[0003] However, the existing exterior walls of prefabricated buildings are still in their infancy. Generally, there are two types of sandwich structures combining cement and thermal insulation materials and two sandwich structures. There are some common problems:

[0004] (1) When applying organic thermal insulation materials to the sandwich structure of prefabricated buildings, the con...
