Preparation process of heat preservation wall for passive house

Abstract

The invention discloses a preparation process of a heat preservation wall for a passive house, which comprises the following steps: during pouring preparation, firstly pouring a lower supporting layer, then sequentially pouring a middle thermal insulation core layer and an upper supporting layer, and pouring concrete layer by layer while pouring the middle thermal insulation core layer, and gradually filling and pouring a material for preparing an insulation board into a partial area of each layer of poured concrete, and carrying out shaping treatment to form an insulation area; until pouring each layer of concrete, wherein the insulation areas in the concrete of all the layers are required to be not overlapped up and down, and the insulation areas of all the layers can cover the whole extending surface of the whole heat preservation wall body on the horizontal projection, so that the insulation areas can be well gathered in the whole wall body, and due to the fact that the concrete is still integrally formed, the strength of the wall body is not affected while the heat preservation effect is good, and the performance of the concrete is guaranteed.

Description

technical field [0001] The invention specifically relates to a preparation process for a thermal insulation wall for a passive house, which belongs to the thermal insulation wall for a passive house. Background technique [0002] At present, with the continuous development of prefabricated buildings, prefabricated buildings are a new direction for the development of buildings due to their simple and fast construction. However, for the current prefabricated buildings, steel frame structures are generally used. Although this method is simple, its thermal insulation performance is poor, and it is difficult to realize the application of passive houses. As for the prefabricated walls of ordinary concrete structures, due to the average thermal insulation performance of concrete, its thermal insulation performance is also limited, which affects the performance of passive houses. In this way, because the insulation board and the wall are not formed at one time, the insulation board...

Problems solved by technology

However, for the current prefabricated buildings, steel frame structures are generally used. Although this method is simple, its thermal insulation performance is poor, and it is difficult to realize the application of passive houses.

As for the prefabricated walls of ordinary concrete structures, due to the average thermal insulation performance of concrete, its thermal insulation performance is also limited, which affects the performance of passive houses. In this way, because the insulation board and the wall are not formed at one time, the insulation board is easy to be damaged after long-term use, especially with the temperature difference between winter and summer, the insulation board will crack and other problems, which will affect the insulation performance.
