A kind of multi-layer composite material building exterior wall thermal insulation decorative board

Abstract

The invention relates to a multi-layer composite building exterior wall heat-insulation decoration plate, which comprises frames, a plate body, a connecting piece and locking mechanisms. The frames are clamped in the outer side of the plate body, the locking mechanisms are arranged in the plate body at equal intervals, and the section of each frame is of a C-shaped structure; the two frames are fixed through the connecting piece, sealing grooves are formed in the outer walls of the bottoms of the frames, sealing plates are mounted at the upper ends of the sealing grooves in a matched mode, thejunctions of the sealing plates and the sealing grooves are fastened through bolts, and the top faces of the fastened bolts are flush with the top faces of the sealing plates; and threaded holes areformed in the positons, above the sealing grooves, of the bottoms of the frames, a metal embossed plate layer is located at the top end of the plate body, a heat-insulation plate layer adheres to thebottom of the metal embossed plate layer, and a moisture-proof plate layer adheres to the bottom of the heat-insulation plate layer. The multi-layer composite building exterior wall heat-insulation decoration plate has the characteristics of energy saving and environmental protection, the plate layers of the heat-insulation decoration plate are connected more tightly, and the fabricated frames areconvenient to transport at the long distance, and are not prone to being extruded and then damaged.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a multilayer composite material building exterior wall thermal insulation decorative board. Background technique [0002] Thermal insulation decorative board, also known as thermal insulation and decoration integrated finished board, is composed of adhesive layer, thermal insulation and decorative finished board, anchors, sealing materials and so on. It is a board with external wall insulation function prefabricated in the factory. The thermal insulation decorative board is composed of thermal insulation material and decorative material, and is used to stick and hang on the exterior wall of the building, and has the functions of heat preservation and decoration. [0003] However, the thermal insulation and decorative panels in the current market will have the following problems during use: a. Since the thermal insulation and decorative panels on the market are all int...

Problems solved by technology

[0003] However, the thermal insulation and decorative panels in the current market will have the following problems during use: a. Since the thermal insulation and decorative panels on the market are all integrated, some old-fashioned thermal insulation and decorative panels will be damaged during some decoration activities such as home decoration It is refurbished, and the integrated thermal insulation decorative panels are difficult to recycle after disassembly, resulting in a large waste of thermal insulation decorative panels. Affected by environmental factors, there will be degumming or separation between the layers of the thermal insulation decorative board, and the service life cannot be guaranteed; b. Due to the optimized design, the frame occupies a large area, which is not convenient for long-distance transportation and is easy to cause damage
