Abstract

The invention relates to a wall body featuring heat preservation and heat insulation, comprising an enclosure wall (1), a washing layer (2) and a facing tier (3). The wall body is characterized in that the enclosure wall (1) is composed of concrete beam columns and light-weight insulating brick masonries, wherein, the masonry mortar applied to the enclosure wall (1) and plastering mortar applied to the washing layer (2) are both a specialized mortar for masonry of light-weight insulating bricks; the raw materials and components mixture ratio of the mortar are as follows: 15-35 parts of pulverized fuel ash, 20-40 parts of perlite, 1-7 parts of swell soil, 1-10 parts of hydrated lime, 1 part of cellulose ether, 200-350 parts of sand, 50-100 parts of pottery sand, and 100 parts of cement. The wall body featuring heat preservation and heat insulation of the invention has outstanding effect in heat preservation and heat insulation, low cost, long service life, no environmental pollution, easy components of raw materials, easy operation of construction, stable construction quality and convenient popularization and application, thus avoiding the problems of heat (cold) bridge and weak heat-insulating property caused by use of ordinary masonry mortar in building the wall body.

Description

technical field [0001] The invention belongs to building walls, in particular to a thermal insulation wall. Background technique [0002] There have been a lot of researches on the thermal insulation technology of walls at home and abroad, and a large number of documents have been retrieved. The main contents of these documents are: [0003] 1. The traditional method of thermal insulation wall is to add a full coverage thermal insulation system to the building wall; [0004] 2. The thermal insulation material used in the thermal insulation layer is mostly composed of polystyrene foam board, rock wool and thermal insulation mortar; [0005] 3. The wall thermal insulation material is mainly composed of adhesive, thermal insulation layer, anti-crack layer and decorative layer; [0006] The original thermal insulation material system has the following problems in actual construction and use: unstable construction quality, complex material composition, complex construction proc...
