Bi-layer thermal-insulating wall with fire protection function

Abstract

The invention relates to a bi-layer thermal-insulating wall with a fire protection function, and belongs to the technical field of building walls. The bi-layer thermal-insulating wall with the fire protection function comprises bricks stacked layer by layer and made of inorganic thermal-insulating materials. A first cavity and a second cavity communicated with the upper side face and the lower side face are formed in each brick, each first cavity is formed between each second cavity and an outer side face, facing outdoors, of each brick, each first cavity is vertically communicated to form a first channel filled with organic thermal-insulating materials, each second cavity is communicated vertically to form a second channel, an inlet channel and outlet channels communicated with the second channels are arranged in the bi-layer thermal-insulating wall, and the inlet channel is communicated with a firefighting water source. The bi-layer thermal-insulating wall with the fire protection function has a building energy conservation effect and can effectively block when fire happens.

Description

technical field [0001] The invention relates to a thermal insulation wall, which belongs to the technical field of building walls. Background technique [0002] The energy consumption of buildings in foreign developed countries accounts for 30% to 40% of the total energy consumption of the society, and the energy consumption per unit area of ​​buildings in my country is still 3 to 5 times that of developed countries with similar climates. Building energy conservation is the most potential and most direct and effective way among various ways of energy conservation. Among the building energy consumption, the energy consumption caused by the external wall accounts for about 60% of the total building energy consumption, so wall insulation is the key to realize building energy saving. [0003] Existing thermal insulation walls include the following types: single material walls, internal thermal insulation composite walls, external thermal insulation walls, and sandwich composite...

AI Technical Summary

Problems solved by technology

However, the thermal insulation performance of the inorganic material insulation board is slightly worse than that of the organic material insulation board, and there is a difference between the thermal expansion coefficient of the organic insulation material and the thermal expansion coefficient of the cement, and the organic material insulation board will fall off, the maintenance cost is high and there are problems.
