Ultralow-energy-consumption passive building vacuum insulation plate and rock wool composite wall and construction method thereof

Abstract

Provided are an ultralow-energy-consumption passive building vacuum insulation plate and rock wool composite wall and a construction method thereof. The wall comprises bottom vertical keels, a composite insulation layer, end seal plate keels, an airtight layer, outer transverse keels, and decorative panels, the composite insulation layer comprises vacuum insulation plates and rock wool plates, the composite insulation layer fills spacing among the bottom vertical keels, the end seal plate keels are fixed to the bottom vertical keels, the airtight layer is spread on the whole wall, the outer transverse keels are arranged in transverse parallel on the surface of the airtight layer and are fixed to the end seal plate keels, and the decorative panels are fixed to the outer transverse keels. The construction method comprises the steps of layout designing, mounting of the outer transverse keels, mounting of the decorative panels and the like. The construction of the insulation system is insusceptible to external environments and is widely applicable to newly-built, extended and reconstructed civil buildings that require thermal insulation.

Description

technical field [0001] The invention relates to a building thermal insulation wall body and a construction method thereof. Background technique [0002] China is a big energy-consuming country. In 2010, the total energy consumption has surpassed that of the United States and ranked first in the world. Among them, building energy consumption has accounted for about 30% of the total energy consumption of the society. In order to reduce building energy consumption, the state requires new residential buildings to strictly implement the energy saving standard of 65%. With the continuous improvement of energy-saving standards, the concept of ultra-low energy passive buildings has begun to be promoted in China, and its insulation mostly uses graphite polystyrene board thin plaster exterior wall insulation technology. Although this technology is widely used, its disadvantages are that organic insulation materials with a thickness of more than 300mm have more prominent fire safety p...
