Building internal wall thermal insulation and fire resistance structure

Abstract

The invention discloses a building internal wall thermal insulation and fire resistance structure. A sticking layer is arranged on a wall body, a thermal insulation layer is arranged on the sticking layer, a strengthening layer is arranged on the thermal insulation layer, a heat preservation layer is arranged on the strengthening layer, a decoration layer is arranged on the heat preservation layer, and a paint face layer is arranged on the decoration layer. The sticking layer is made of bittern glue. The bittern glue is formed by stirring bittern and magnesia powder. The thermal insulation layer is made of a magnesia plate, and the strengthening layer is made of a fiberglass mesh and bittern glue. The heat preservation layer is made of an extruded sheet, and the decoration layer is made of a gypsum board. The paint face layer is made of an antirust coating, a thermal insulation coating and a fire resistance coating. The building internal wall thermal insulation and fire resistance structure is good in overall sealing performance and capable of improving the thermal insulation effect of a building, reducing the heat flow loss and reducing the energy consumption of the building and capable of achieving the thermal insulation purpose.

Description

technical field [0001] The invention relates to a building wall, in particular to a building inner wall thermal insulation and fire prevention structure. Background technique [0002] Inner wall insulation is the same as the outer wall insulation technology, and it is used as an important building energy-saving technology in construction engineering. At present, foam insulation boards are mainly used for building inner wall insulation. This kind of thermal insulation material has complex construction process, high follow-up cost, poor durability of wall mildew through cold, flammable (the cost of using flame retardant is high), combustion produces a large amount of toxic gas, and once it catches fire, it will cause serious consequences, and the cost is high, so it is not suitable Due to the construction of special-shaped and complex structures, a large number of plate seams form thermal bridges, which poses serious safety hazards. Contents of the invention [0003] The o...
