A form-retaining integrated board used in the external thermal insulation system of building exterior walls

Abstract

The invention discloses an insulation and formwork integrated board for a building external wall external thermal insulation system. The insulation and formwork integrated board comprises an inner side board, a plurality of vacuum thermal insulation board, an outer side board, an outer semi screw, an outer semi threaded sleeve, an inner semi screw, an inner semi threaded sleeve and a plurality of nuts. A thermal insulation effect is good, insulation and construction are simple and efficient, and the connecting strength of layers is high.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a form-retaining integrated board used for an external thermal insulation system of a building exterior wall. 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 buildings are also required to undergo energy-saving ...
