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.
