passive house

Abstract

The invention relates to a passive steel structure house, which includes a foundation, a side wall and a roof. The bottom end of the side wall is located below the upper surface of the foundation. The side wall includes a steel structure inner wall. layer, the side of the wall insulation layer away from the inner wall of the steel structure is provided with an external protective wall; the roof includes the roof foundation and the roof decoration protection structure above the roof foundation, and the roof foundation includes the roof steel frame layer, the first roof foundation layer, the roof The insulation layer, the second roof base layer, the roof leveling layer and the roof waterproof layer, the roof foundation protrudes to the outer side of the inner wall of the steel structure, and the top end of the wall insulation layer is provided with a shielding piece, forming a gap between the shielding piece and the roof foundation The filling area of ​​the top opening is filled with thermal insulation filler, and the top opening of the filling area is provided with a sealing piece. The invention has the function of improving the thermal insulation performance of the house, so that the internal temperature of the house is not easy to lose.

Description

technical field [0001] The invention relates to the technical field of steel structure houses, in particular to a passive steel structure house. Background technique [0002] At present, the technology of building houses with steel structures is quite common. Steel structures have comprehensive advantages such as light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures Compared with steel structure, it has the characteristics of "high, large and light" in three aspects. On a global scale, especially in developed countries and regions, steel structures have been reasonably and widely used in the field of construction engineering. [0003] Compared with traditional reinforced concrete and brick concrete buildings, steel structure houses have many advantages, but due to the high thermal conductivity of steel itself, which ...

AI Technical Summary

Problems solved by technology

[0003] Compared with traditional reinforced concrete and brick concrete buildings, steel structure houses have many advantages, but due to the high thermal conductivity of steel itself, which is 33.4 times that of concrete, resulting in heat conduction between indoors and outdoors The current conventional practice is to lay insulation layers on the side walls and roof surfaces to reduce heat loss

[0004] However, due to the poor sealing effect of the joint between the roof and the side wall, a large amount of high temperature from the outside will be transmitted to the room in a short period of time, or when the environment outside the wall is in a low temperature environment, the higher temperature in the room will be lost to the outside of the wall. These factors cause The room cannot maintain a suitable temperature environment for a long time
