A building exterior wall heat insulation structure

Abstract

The invention discloses a thermal-insulation structure of an exterior wall of a building. The thermal-insulation structure of the exterior wall of the building comprises a wall body, wherein a buffering layer is arranged on the outer wall of the wall body; an aluminum foil layer is arranged on the other surface of the buffering layer; a reflective thermal-insulation layer coats the other surface of the aluminum foil layer; a protective layer coats the reflective thermal-insulation layer; and the buffering layer consists of elastic glue sticks and rock wool, namely a plurality of through holes are equidistantly formed in a rock wool plate, and the elastic glue sticks are inserted in the rock wool plate to form the buffering layer. The thermal-insulation structure of the exterior wall of the building is simple and reasonable, can meet construction conditions due to high mechanical property, has good impact resistance, and is obvious in thermal-insulation effect; different layers are connected to one another firmly, and circumstances of deformation, falling and the like are not easily caused; and flame-retardant and sound-insulation properties are excellent. The whole structure is simple in construction, short in period, relatively low in cost, long in service life and attractive in appearance, is used safely and reliably, and is suitable to be popularized and used in regions with abundant sunlight resources.

Description

technical field [0001] The invention relates to the technical field of building exterior walls, in particular to a building exterior wall heat insulation structure. Background technique [0002] Classified according to the position and direction of the wall in the building: it is divided into two types: exterior wall and interior wall. The walls arranged along the perimeter of the building are called exterior walls, and the walls surrounded by exterior walls are called interior walls. The external environment and the building's indoor thermal environment mainly conduct heat transfer through three forms of heat radiation, heat convection and heat conduction, which affect the temperature of the indoor environment and the energy saving of buildings. At present, the conventional external wall insulation system mainly adopts the method of blocking to reduce heat conduction. Nowadays, all kinds of external thermal insulation materials for external walls generally have poor bondi...

AI Technical Summary

Problems solved by technology

Nowadays, all kinds of external insulation materials for external walls generally have poor bonding with the base wall. Under the influence of external forces such as freeze-thaw resistance and wind pressure, they are prone to deformation and falling off, resulting in a decrease in the barrier performance of the wall.

Especially in recent years, the shortcomings of flammability of some organic types of external wall insulation materials that have been widely used in practical applications have also been highlighted intensively. At the same time, the existing external walls do not have the effect of sound absorption and sound insulation, or the effect Not ideal, so it is necessary to improve the design, installation, anchoring process and flame retardancy of the external wall insulation and sound-absorbing system
