A thermal insulation system for building exterior walls and its construction method

Abstract

The invention discloses a thermal insulation system for building exterior walls, which comprises an exterior wall substrate, a mortar bonding layer, a thermal insulation board and a pouring fixed substrate, the thermal insulation board is laid on the exterior wall substrate through the mortar bonding layer, and several of the The thermal insulation boards are arranged in a rectangular array, and two adjacent thermal insulation boards are stacked in the upper and lower directions, and a pouring cavity is formed between the two adjacent thermal insulation boards in the horizontal direction and the mortar bonding layer, and the The pouring cavity is vertically arranged up and down, the pouring cavity is provided with a pouring fixed base, and the pouring fixed base and the outer wall base are relatively fixed, and the pouring cavity is provided with a thermal insulation filling body, which can ensure that the thermal insulation layer and the outer wall base are relatively fixed. Strengthen the bonding strength of the outer wall matrix and prevent the insulation layer from falling off.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a thermal insulation system of a building exterior wall and a construction method thereof. Background technique [0002] Building thermal insulation mainly takes measures from the building envelope structure, and at the same time, measures to reduce the indoor heat of the building to the outside play an important role in creating a suitable indoor thermal environment and saving energy. Existing commonly used thermal insulation formwork for exterior walls of buildings is multi-layer composite thermal insulation external formwork, which is only bonded to the external wall by wall nails or mortar. However, the exterior wall matrix is ​​the main body of heat transfer. During use, the thermal insulation external template and Due to the thermal expansion and contraction of the external wall itself, there is often a hollowing phenomenon between the internal insulation layer and t...

Problems solved by technology

Existing commonly used thermal insulation formwork for exterior walls of buildings is multi-layer composite thermal insulation external formwork, which is only bonded to the external wall by wall nails or mortar. However, the exterior wall matrix is ​​the main body of heat transfer. During use, the thermal insulation external template and Due to the thermal expansion and contraction of the external wall itself, there is often a hollowing phenomenon between the internal insulation layer and the external bond, and the thermal insulation external panel is easy to crack and fall off with the external wall matrix, which brings great damage to the building. People and things under it cause a great safety hazard
