Phenolic foam insulation and decoration integration board external wall insulation system

Abstract

The invention belongs to a phenolic foam insulation and decoration integration board external wall insulation system. A phenolic foam insulation board (11) is bonded to a base course wall (1) through bonding mortar (7), and an aluminum-zinc coated steel sheet (10) is fixed on the outer surface of the phenolic foam insulation board (11) through aluminum pulling rivets (4). The phenolic foam insulation and decoration integration board external wall insulation system is characterized in that the integrated phenolic foam insulation board (11) and the aluminum-zinc coated steel sheet (10) which are adjacent to each other are fixedly connected by a U-shaped corner brace (9) through the aluminum pulling rivets (4); the U-shaped corner brace (9) is fixedly connected with an L-shaped bracket (2) through a round-head self-tapping screw (8), and the round-head self-tapping screw (8) is fixed on the base course wall (1) through a mechanical anchoring part (6). The phenolic foam insulation and decoration integration board external wall insulation system is low in self-weight and convenient to construct and thoroughly solves the problems of hollowing and falling of a building external wall insulation system; external wall insulation system fire accidents are completely eradicated.

Description

technical field [0001] The invention belongs to the technical field of external heat preservation of building exterior walls, and in particular relates to a phenolic foam heat preservation and decoration integrated board exterior wall heat preservation system. Background technique [0002] In recent years, domestic building insulation has been dominated by thin plastering systems for exterior walls. However, almost all thin plastering systems for exterior walls have quality defects of varying degrees, such as cracking, hollowing, water seepage, and falling off of the plastering surface. [0003] In order to solve the above problems, people are devoting themselves to the research on the thermal insulation system of the external wall of the thermal insulation and decoration integrated board. At present, the thermal insulation materials of thermal insulation and decoration integrated panels in the building materials market are still mainly flammable foam materials, such as mold...

AI Technical Summary

Problems solved by technology

These foam insulation materials are extremely flammable and release a large amount of highly toxic gas after burning, posing a huge threat to people's lives and property safety

[0004] In addition, the surface materials of domestic thermal insulation and decoration integrated boards are generally calcium silicate boards and cement fiber boards, which are heavy in weight and stable in construction, and are prone to deformation and warping under sunlight
