Exterior wall fireproof composite board with built-in keel

Abstract

The invention relates to an exterior wall fireproof composite board with a built-in keel. The exterior wall fireproof composite board successively comprises a backboard layer, a heat-insulation layer and a surface decoration layer outwardly from an exterior wall, the keel is embedded in the heat-insulation layer, and the backboard layer, the heat-insulation layer and the surface decoration layer are bonded with each other to form the composite board. The exterior wall fireproof composite board also comprises wall anchoring members for fixing and connecting the composite board to the wall. The keel is an aluminum alloy keel of a structure shaped like a Chinese character 'jing', 'tian', 'wang', or 'shi'. The exterior wall fireproof composite board has the advantages that through building the aluminum alloy keel in the heat-insulation layer, wind load anti-compression performance of the whole composite board is largely enhanced, and collapse and deformation of the whole composite board are effectively prevented; and service lifetime of exterior wall heat-insulation materials is effectively prolonged, and heat-insulation lifetime of the exterior wall can be prolonged to be over 10-15 years.

Description

technical field [0001] The invention belongs to the fields of heat preservation, fire prevention, energy saving and decoration of building exterior walls, and in particular relates to a fireproof composite board for exterior walls with built-in keels. Background technique [0002] At present, almost all new buildings in my country need to add thermal insulation and decorative surfaces to the external walls. In order to improve the performance of thermal insulation products and achieve convenient construction, many building materials have realized the combination of thermal insulation and decorative surfaces, forming many thermal insulation decorations. Integrated panels, but most of the insulation materials are below the B2 standard, and the fire protection rating of building decoration materials needs to be improved urgently. [0003] At this stage, the external wall insulation board materials used in the market all have a common feature, that is, all insulation materials ar...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems of deformation and collapse of thermal insulation materials at the present stage, and the decrease of wind load compressive performance and thermal insulation coefficient year by year, the present invention provides an external wall thermal insulation and fireproof composite panel with built-in isolation keel, which greatly enhances the overall wind load compressive performance of the composite panel. Effectively prevent the overall collapse and deformation of the composite panel
