Flame-retardant outer wall heat-preserving decorative plate

Abstract

The invention discloses a flame-retardant outer wall heat-preserving decorative plate which comprises an outer panel and an inner panel. Two square hole tubes are arranged in parallel between the upper ends and the lower ends of the outer panel and the inner panel in the horizontal direction, the upper end face of the upper square hole tube and the upper end face of the outer panel or the inner panel are located in the same horizontal plane, the lower end face of the lower square hole tube and the lower end face of the outer panel or the inner panel are located in the same horizontal plane, the two outer sides, abutting against the outer panel and the inner panel, of the square hole tubes are coated with a high-strength adhesive, inner square holes serve as safety rope hanging holes, and at least a pair of anchoring holes are symmetrically formed in the inner panel in a penetrating mode. The flame-retardant outer wall heat-preserving decorative plate is simple in structure; on one hand, heat preservation is achieved through an air layer between the outer panel and the inner panel, so that use of combustion-supporting heat-preserving materials is avoided, and resources are saved; on the other hand, the outer panel and the inner panel are effectively connected through the square hole tubes, the inner square holes serve as the safety rope hanging holes, and connection reliability and safety are greatly improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a flame-retardant exterior wall thermal insulation decorative board. Background technique [0002] Exterior wall thermal insulation decorative board is a new type of building exterior wall decoration and thermal insulation integrated material developed in recent years. It is mainly used in the exterior wall decoration and energy-saving renovation of gymnasiums, libraries, school and hospital office buildings, villas and other buildings. [0003] Most of the existing external wall thermal insulation decorative panels are provided with thermal insulation materials. Although the thermal insulation effect is good, on the one hand, the materials of this thermal insulation layer are mostly flammable. The material will increase the overall weight of the exterior wall insulation and decorative panels, thereby increasing the requirements for anchors. When there is a problem wit...

[0003] Most of the existing external wall thermal insulation decorative panels are provided with thermal insulation materials. Although the thermal insulation effect is good, on the one hand, the materials of this thermal insulation layer are mostly flammable. The material will increase the overall weight of the exterior wall insulation and decorative panels, thereby increasing the requirements for anchors. When there is a problem with the anchors, the safety hazard is high
