A waterproof exterior wall thermal insulation decorative board and its installation method

Abstract

The invention belongs to the technical field of building materials, in particular to a waterproof exterior wall thermal insulation decorative board and an installation method. It consists of thermal insulation laminates and structural decorative laminates fixedly connected by cementing materials. The structural decorative laminates include structural anchoring ribs, corner lines and decorative panels, wherein the structural anchoring ribs are located between the thermal insulation laminates and the structural decorative layers. between the boards, and the structural anchoring ribs are fixedly connected with the corner lines, the corner lines are connected to each other to form a closed frame, the decorative panel is fixed in the closed frame, and the structural anchoring ribs are used to fix the thermal insulation decorative board on the wall The technical scheme on the body has good thermal insulation effect, good waterproof effect, simple production, simple construction, and can greatly save construction time. It is in line with the current national advocacy of factory production and simplified construction, and meets the needs of the current construction industry.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a waterproof exterior wall thermal insulation decorative board and an installation method. Background technique [0002] With the rapid development of my country's economy, higher and higher requirements for energy saving and emission reduction have been put forward, and the country has put forward mandatory insulation standards for the external wall insulation of buildings, advocating factory production and simplifying construction. In order to realize the thermal insulation of external walls, most construction units adopt the method of bonding thermal insulation boards with polymer bonded mortar for thermal insulation construction. Specifically, first use polymer bonding mortar to paste insulation boards (extruded polystyrene boards, foamed polyurethane boards, etc.) The cement mortar calendered surface is painted with exterior wall paint, or pasted with exterior wa...

Problems solved by technology

The disadvantages of this method are: first, the construction is difficult and requires a large amount of labor; second, the bonding is not firm, and there are quality and safety hazards such as cracking and falling off; third, there is a hidden danger of water leakage, which is one of the common problems in the current construction industry. It is called a common problem; in addition, due to the fact that the above-mentioned extruded polystyrene boards and foamed polyurethane boards are not fireproof, they are less and less used in the construction industry, and from the perspective of fire prevention, rock wool, glass wool, and phenolic foam boards have already been used. It is more and more used in the insulation of external walls, but it is very inconvenient to use the above-mentioned fireproof materials, or the materials are too brittle and easy to damage, or the shape is irregular, and it is not easy to fix. The thicker the insulation, the more difficult it is to fix it, which is the thorny problem encountered at present

Although there are also composite thermal insulation decorative panels for construction, the design of the structure is not reasonable enough. There are gaps at the junction of the panels, which need to be jointed on site, resulting in poor sealing performance, and there are also cold bridges for heat dissipation and rainwater is easy to pour into. problems that affect the quality of the exterior walls
