Waterproof thermal-insulation decorative wall board, casing for doors and windows, and installation method of casing

Abstract

The invention belongs to the technical field of building materials, in particular to a waterproof thermal-insulation decorative wall board, a casing for doors and windows, and an installation method of the casing. The waterproof thermal-insulation decorative wall board comprises thermal-insulation boards including an upper layer and a lower layer staggered, a structural board and a facing board are sequentially attached to the surface of each thermal-insulation board, the structural board comprises a mesh layer, structural anchor bars and cement mix, each structural anchor bar is provided with a fixing hole, edge and corner lines are arranged between the structural board and the facing board, the edge and corner lines include functional areas and anchor areas, a separation frame is arranged at the connection of the functional areas and the anchor areas, the edge and corner lines include an upper edge and corner line I, a left edge and corner line II, a right edge and corner line III and a lower edge and corner line IV. According to the technical scheme, the waterproof thermal-insulation decorative wall board is simple in structure and convenient in use and serves as a fine exterior wall decoration, is evidently effective and has prominent substantial characteristics and evident progress.

Description

technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a waterproof wall thermal insulation decorative board, a wire sleeve for doors and windows 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 thermal insulation standards for the external wall insulation of buildings. 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 wall tiles, et...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: firstly, the construction is difficult and labor-intensive; secondly, the bond is not firm, and there are quality and safety hazards such as cracking and falling off, which is one of the common problems in the current construction industry; in addition, for the above-mentioned extrusion Polystyrene boards, foamed polyurethane boards, etc. are less and less used in the construction industry because they are not fireproof, and from the perspective of fire protection, rock wool, glass wool, and phenolic foam boards have been 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 be damaged, or the shapes are irregular and difficult to fix. It is very inconvenient to form a whole, and it is also highly water-absorbent. These are the thorny problems 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, resulting in poor sealing performance, and it is easy to pour rainwater, which affects the quality of the outer wall.

[0003] In addition, in the existing exterior wall decoration, the processing work on the doors and windows, the outer panel of the air conditioner, the overhanging eaves and other structures is relatively cumbersome, or the structure of the auxiliary parts used is complicated, which is inconvenient for construction and prolongs the construction time
