Exterior wall insulated structure and building method thereof

Abstract

The invention discloses an exterior wall insulated structure, which comprises an inner layer consisting of concrete, an outer layer arranged on the outer side of the inner layer and consisting of fiber cement motar and an insulated layer arranged between the inner layer and the outer layer. The invention also discloses a method for building an insulated exterior wall, which comprises the following steps of: a) fixedly arranging steel bars for the wall, and arranging the insulated layer between the steel bars of the inner layer and the outer layer; b) arranging a steel mould, and determining the arranging position of the steel mould according to the thickness of the wall; c) simultaneously casting concrete on the inner side and the outer side of the insulated layer in the steel mould; and d) after the concrete is solidified, disassembling the steel mould. The exterior wall insulated structure is convenient to build; and because the concrete is simultaneously cast on two sides of the insulated layer in a fluid fit mode, the outer layer, the inner layer and the insulated layer are tightly attached, air gaps and moisture are difficult to generate in the middle, the insulation effect is improved and the service life is prolonged.

Description

technical field [0001] The invention relates to an outer wall thermal insulation structure and a method for building the outer wall. Background technique [0002] Due to the increasingly tense international energy supply, in order to make my country's social and economic sustainable development, building energy conservation has been paid more and more attention by the national construction department, especially in the northern region of our country. In autumn and winter, the temperature difference between indoor and outdoor is large. Indoor insulation will cause heat dissipation, which is very detrimental to energy conservation and environmental protection. [0003] The external wall insulation structure in the prior art is generally as figure 1 As shown, from outdoor to indoor, there are exterior wall layer 1, interface agent layer 2, thermal insulation material layer 3, anti-cracking mortar reinforcement layer 4, flexible water-resistant putty layer 5, and paint layer 6. ...

AI Technical Summary

Problems solved by technology

However, because its processing is carried out in layers, its construction is not very convenient. The additives used between layers increase the cost of external wall insulation, and at the same time, it is easy to form voids and moisture in the wall. In winter in the north, the temperature difference between day and night is extremely large, and the water vapor in the wall undergoes a continuous process of condensation-melting-re-condensation-re-melting, which makes the gaps in the wall more and more expanded, and the water vapor accumulates more and more. Too much, it is easy to cause the wall to fall off, thus shortening the service life of the wall
