Energy-saving heat preservation thermally insulated wall and method of construction

Abstract

The invention discloses a heat insulation wall with energy saving and the construction method. The heat insulation wall comprises an inner wall, a middle wall and an outer wall. Inner and outer walls are set by foam concrete prefabricated bricks with E-shape section and higher intensity. The middle wall, which is cast in case, is the foam concrete self-heat insulation wall with good heat insulation performance. The invention also contains the construction of said heat insulation wall. The structure of invention is simple and cool-hot bridge can not be generated. It is provided with good heat insulation performance and there is no need to build another outer wall to reserve heat. Not only the cost is saved but also standards of environmental protection and energy saving can be guaranteed. Compared the heat insulation wall constituted by clay wall and outer heat insulation wall, the cost can be saved more than 30%.

Description

technical field [0001] The invention relates to an energy-saving heat-preservation and heat-insulation wall body and a construction method thereof, in particular to an energy-saving heat-preservation heat insulation foam concrete wall body and a construction method thereof. Background technique [0002] At present, more than 60% of the external walls of buildings in the country still use solid clay bricks or hollow clay bricks, resulting in the reduction of cultivated land and the deterioration of the ecological environment. Building a 240mm thick wall (thermal conductivity 0.58) consumes a lot of energy. To meet energy-saving standards, it is necessary to use 40mm thick polystyrene foam (thermal conductivity 0.042) as the outer wall insulation layer, and the insulation layer should only be brushed Apply exterior wall paint instead of pasting exterior wall tiles. [0003] In order to develop energy-saving buildings, various lightweight thermal insulation new wall materials ...

AI Technical Summary

Problems solved by technology

The above-mentioned materials are bulky and difficult to masonry; the thermal insulation effect of the materials is greatly reduced due to the cold and heat bridges generated by the masonry mortar

In addition, the external wall insulation layer must be used to meet the national environmental protection and energy saving standards, which further increases the construction cost, so there is great resistance to popularization and application

No. 200420080498.9 discloses an aerated concrete self-insulation wall, although its thermal insulation effect is good, but the structure is quite complicated, and it is difficult to popularize and apply

No. 200510047439.0 discloses a method for making light-weight wall materials for on-site foamed concrete. Hydrogen peroxide and aluminum powder are used as foaming agents. Construction under the condition of above 20 ℃ will also bring a lot of inconvenience to the construction
