Thermal insulation structure for building

Abstract

The invention relates to a thermal insulation structure for a building and a construction technology. The construction technology comprises the steps that an insulating layer is nailed to a wall body basic layer, then a special reinforcing grid is supported by preset special buckles, the special reinforcing grid is pressed on and covers the insulating layer through the assisting of expansion anchor bolts, and the special reinforcing grid and the insulating layer are fixed to the wall body basic layer, so that all the loads of the insulating layer and the externally-hung special reinforcing grid are completely borne by the expansion anchor bolts and transmitted to the wall body basic layer; and scraping operation, covering operation and leveling operation are conducted on the externally-hung special reinforcing grid through thermal-insulating particle slurry. The thermal insulation structure for the building and the construction technology can effectively solve the technical problems that combination between a conventional exterior wall external insulation system and a basic layer wall body is poor, water seepage easily happens, and surface treatment is difficult. In addition, due to the fact that various materials adopted by the thermal insulation structure for the building and the construction technology are incombustible materials with the fireproof grade higher than A, the fire prevention hidden danger of a conventional exterior wall external insulation material is eliminated.

Description

technical field [0001] The invention relates to an external thermal insulation structure and a construction process of an external wall of a building, and is a novel external thermal insulation structure and a construction process of a building wall. Background technique [0002] 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 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 o...
