Heat-insulation construction and energy conservation process for exterior walls

Abstract

The invention relates to a heat-insulation construction and energy conservation process for exterior walls. The scheme includes that the heat-insulation construction and energy conservation process includes particular steps of cleaning and processing base layers; adjusting control lines and hanging datum lines; adhering graphite and polystyrene foam plates; fixing SEPS (styrene-ethylene / propylene-styrene block copolymer) plates in an adhesion mode by the aid of a point-frame method or a strip adhesion method; constructing surface layers. The heat-insulation construction and energy conservation process has the advantages that the heat-insulation construction and energy conservation process is simple, and good heat-insulation effects can be realized; heat-insulation layers are made of graphite and polystyrene foam and are light and safe as compared with the traditional heat-insulation systems, the weights of the heat-insulation layers only account for 60% of the weights of the traditional molded plasticized polystyrene and thin plasticized polystyrene plastered systems, the thicknesses of the heat-insulation layers are equivalent to 50% of the thicknesses of the traditional plastered systems, and accordingly the purpose of saving energy by 65% can be easily achieved; the graphite and polystyrene foam has a fireproof function and is applicable to optional wall surfaces and wide in application range.

Description

Technical field [0001] The invention belongs to the field of thermal insulation construction of external walls of buildings, and mainly relates to an energy-saving process for thermal insulation construction of external walls. Background technique [0002] At present, the energy crisis has become a major problem faced by mankind all over the world. The lack of energy will hinder the progress of mankind, which requires the global attention and attention. Our country attaches great importance to energy issues, and has listed sustainable development and the establishment of a conservation-oriented society as a basic national policy of our country. As a new building energy-saving technology, external wall insulation technology can not only save energy and resources, but also improve the utilization rate of energy and resources. At present, the external wall insulation system that people often use includes a variety of insulation materials and different construction techniques, such ...

Problems solved by technology

At present, the external insulation system of external walls that people often use includes a variety of insulation materials and different construction techniques, such as the external insulation system of rubber powder EPS particle slurry, the external insulation system of cast-in-place concrete composite non-mesh EPS board, and the composite EPS steel wire of cast-in-place concrete. Mesh external thermal insulation system, EPS board thin plaster external wall external thermal insulation system, mechanically fixed EPS steel wire grid panel external thermal insulation system, rock wool external thermal insulation system, hard foam polyurethane external thermal insulation system, etc., in these external wall external thermal insulation systems Among them, the EPS board thin plaster exterior wall external insulation system has good thermal insulation performance, superior water resistance, compression resistance, impact resistance, mature and reliable technology, etc., and is currently the most widely used external wall external insulation technology. However, under the condition of achieving the same effect, the fireproof ability and heat insulation ability of EPS are poor, and at the same time, it is more polluting to the environment.
