Abstract
The invention belongs to the technical field of architectural decoration, and discloses an external heat insulating system of an external wall thinly plastered with a polyphenyl plate and a construction method thereof. The external heat insulating system of the external wall thinly plastered with the polyphenyl plate comprises the polyphenyl plate, a protecting layer and a finishing coat which are arranged on the foundation wall body sequentially; a gap is reserved between two adjacent heat insulating plates; air exhaust grooves with openings towards the foundation wall body are arranged in the gaps, and the air exhaust grooves at the intersecting part of the gaps are communicated with each other; the back of the air exhaust groove is provided with a filler; and the air exhaust groove is provided with vents so that the air exhaust groove is communicated with the gap between the polyphenyl plate and the foundation wall body. The external heat insulating system of the external wall has the advantages that hydrosphere inside a building can be released to the atmosphere in time, so as to avoid vapor from condensing between the polystyrene heat insulating plate and the wall body, and between the heat insulating layer and the protecting layer; the finishing coat is effectively prevented from frothing and cracking; and the thermal performance of the external heat insulating system is ensured.
Description
technical field [0001] The invention relates to an external wall thermal insulation system and a construction method thereof, in particular to an external thermal insulation system of a polystyrene board thinly plastered external wall and a construction method thereof. Background technique [0002] The outer wall occupies the largest proportion in the building envelope, accounting for about 50% of the total building area, and the heat loss through the wall accounts for about 25% of the heat loss of the entire building. Therefore, the insulation of the outer wall is to reduce the building energy. One of the keys to consumption. "JGJ 44-2004 Technical Regulations for External Wall Thermal InsulationEngineering" stipulates the following five external thermal insulation methods: expanded polystyrene board (EPS board) thin plaster external thermal insulation system, rubber powder EPS particle thermal insulation slurry external wall External thermal insulation system, EPS board ...
