Building sandwich thermal insulation board

Abstract

The invention relates to a building sandwich thermal insulation board, and belongs to the technical field of building materials. The building sandwich thermal insulation board comprises a heat preservation plate body, a plurality of outer limiting convex bodies are evenly distributed on the outer side of the heat preservation plate body, a plurality of outer surface vertical grooves are verticallydistributed in the outer side of the heat preservation plate body, and a plurality of inner surface outer convex bodies and inner surface concave bodies are evenly distributed at the inner side of the heat preservation plate body. The thickness of an outer protection layer of the thermal insulation board is effectively limited, and the bonding force of protection concrete and the thermal insulation board is enhanced. Construction is convenient, construction waste is reduced, and manual work days are reduced. The project time limit is shortened, factory production is achieved, and the thermalinsulation board and a steel wire net frame are formed at the same time. The building sandwich thermal insulation board has the effects of heat preservation, heat insulation, fire prevention, water prevention, durability, sound insulation, sound absorption, corrosion prevention, land saving, material saving, time saving and service life prolonging.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building sandwich insulation board. Background technique [0002] With the acceleration of the urbanization process, more and more people live in commercial housing, which improves the living conditions, but the current building wall structure is single, and the building insulation boards currently on the market have relatively flat internal and external surfaces. The adhesion is not enough, and the thickness of the outer protective layer of the insulation board will be relatively thick, which is wasteful for the use of materials. Contents of the invention [0003] The object of the present invention is to provide a building sandwich insulation board which effectively limits the thickness of the outer protective layer of the insulation board and enhances the bonding force between the protective concrete and the insulation board. [0004] In order to achieve the pu...

At present, the building insulation boards on the market have relatively flat internal and external surfaces. The adhesion is not enough, and it will lead to a relatively thick thickness of the outer protective layer of the insulation board, which is wasteful for the use of materials
