Integrated structure and construction method of external wall thermal insulation reinforced composite board and thermal insulation wall

Abstract

The invention provides a reinforced composite plate for external wall insulation, an integrated structure of an insulation wall body and a construction method. The reinforced composite plate for external wall insulation comprises a reinforced insulation plate and a light-weight concrete poured and compressed protection layer, wherein the reinforced insulation plate comprises two parallel rebar welded mesh sheets A and B with same size and same shape and an insulation plate; the mesh sheets A and B are respectively arranged on both sides of the insulation plate and are welded and fixed by connecting rebars; a fixing sheet is arranged between the mesh sheet A and the insulation plate; the protection layer with a certain thickness is arranged on the other side of the insulation plate; grooves or skewed slots of 5 to 10 mm are formed around the protection layer. During construction, the rebar welded mesh sheet A in the reinforced composite plate for external wall insulation is arranged in an external wall and is connected with a main bar, a stirrup and a structural tiepiece in the external wall through fine tie bars or an enough anchoring length is left in the external wall body. The reinforced composite plate for external wall insulation manufactured by the method is convenient to manufacture and mount, has obvious insulation and fireproofing effects, and is convenient to construct; the service life of the reinforced composite plate is the same as that of a structure.

Description

technical field [0001] The invention belongs to the field of wall construction, and in particular relates to an external wall thermal insulation reinforced composite board, an integrated thermal insulation wall structure and a construction method. Background technique [0002] At present, the insulation of building exterior walls is mostly made of organic materials, such as extruded polystyrene boards, polystyrene boards, etc., and the installation and construction methods of external sticking and hanging are adopted. Due to the limitation of materials, this kind of insulation board has low fire protection level, flammability, and not easy to stick to dust. When it is used for building exterior wall insulation construction, it will lead to difficult construction, easy cracking and falling off, poor fire insulation effect, and many safety hazards. And other problems, especially the construction method of hanging the insulation layer outside the wall, its service life is short...
