Construction method of an external wall thermal insulation system

Abstract

The invention discloses a waterproof supporting piece which comprises a first vertical platy part, a first horizontal platy part and a second vertical platy part.By means of the waterproof supporting piece, an external wall external heat preservation system can be simpler in structure, lower in production and construction cost, higher in connection strength with a wall foundation, convenient and rapid to install and construct, few in internal and external cold and heat bridge phenomenon, and good in waterproof effect.The invention further discloses a heat preservation and decoration integrated plate with the waterproof supporting piece, the external wall external heat preservation system with the waterproof supporting piece, and a construction method of the external wall external heat preservation system.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof support, an integrated thermal insulation and decoration board, an external thermal insulation system for an exterior wall, and a construction method. Background technique [0002] my country's building energy consumption accounts for about 30% of the country's total energy consumption. Building energy conservation is a very important task to alleviate my country's energy shortage, improve people's living and working conditions, reduce environmental pollution, and promote sustainable economic development. Building energy conservation mainly includes three parts: thermal insulation of building roofs, thermal insulation of building exterior maintenance walls and exterior doors and windows, and energy conservation of building equipment. In October 2007, the state issued a document requiring that new buildings across the country must be insulated, and existing...
