Energy-saving heat insulation wall

Abstract

The invention provides an energy-saving heat insulation wall, which relates to a building wall and aims at solving the problems that a thin coat plastering heat insulation wall is poor in fire protection, more in wet operations and high in manufacturing cost, has influence to energy conservation, etc. The energy-saving heat insulation wall can be constructed into the following structures: 1, the wall comprises a base layer wall, a prefabricated heat insulation board and an anchor bolt, wherein a protective layer is arranged on the side surface of a heat insulation layer of the prefabricated heat insulation board, the heat insulation layer is connected with the protective layer, the prefabricated heat insulation board is arranged on the side surface of the base layer wall, and the anchor bolt penetrates through the prefabricated heat insulation board, so that the prefabricated heat insulation board is fixed with the base layer wall, or the prefabricated heat insulation board is bonded with the base layer wall by cementing material, or is connected with the base layer wall in a clamping way; 2, the wall comprises a base layer wall, a heat insulation layer, an anchor bolt and a protective layer, wherein the heat insulation layer is arranged on the side surface of the base layer wall, the prefabricated board protection layer is arranged at the outer side of the heat insulation layer, and the anchor bolt penetrates through the prefabricated board protection layer and the heat insulation layer, or the prefabricated board protection layer is connected with the heat insulation layer in a bonding way, so that the prefabricated board protection layer is fixed with the heat insulation layer and the base layer wall. The energy-saving heat insulation wall is fireproof and safe during construction and during long-time application, and is convenient in prefabrication and installation, low in manufacturing cost and good in energy conservation and heat insulation, thus promoting housing industrialization.

Description

technical field [0001] The invention relates to an energy-saving and heat-preserving wall body of a building. Background technique [0002] Tests have proved that it is effective to install fireproof isolation strips on thin plastered insulation walls to block the spread of fire, but the range of sacrificial layers is large: three layers to one layer. The quality of the thin plaster insulation wall protection layer is very difficult to control in my country. The quality problem of alkali-resistant mesh breakage is almost universal. [0003] Moreover, the protective layer of the thin plastered thermal insulation wall of the organic thermal insulation material contains polymer adhesive, and the protective layer itself is combustible. This is the root cause of the fire hazard of the thin plastered thermal insulation wall with organic thermal insulation materials. [0004] When the ignition point of the inorganic thermal insulation material is low and there is air between the t...

AI Technical Summary

Problems solved by technology

However, if the thickness of the protective layer is increased to, for example, 40-50mm, it is almost unfeasible in construction.

[0014] The applicant of this patent has applied for several patents on external thermal insulation walls, which have greatly improved the fire performance, energy saving and thermal insulation performance of thin plastered external thermal insulation walls, but there are many wet plastering operations on site and the construction is inconvenient. There is still the problem that it is not feasible when the plaster is required to be thicker, and there are still fire safety hazards in the construction, and it is still necessary to use expensive thermal insulation materials with a combustibility not lower than B1 level in most projects
