Description

Technical Field

[0001] The invention relates to an assembled house. Background Art

[0002] In recent years, a large number of prefabricated farmhouses have sprung up in rural areas, making the research on prefabricated farmhouses more socially valuable.

[0003] However, for rural areas in severe cold regions, the development of prefabricated farmhouses still faces many challenges. On the one hand, due to the influence of the low temperature climate in severe cold regions, the requirements for the thermal insulation performance of farmhouses in severe cold regions are generally higher than those in other climate zones. In addition, the heat loss caused by the thermal bridge effect during the operation and maintenance of residential buildings due to the large temperature difference between indoor and outdoor in winter will also be more serious. At the same time, with the advancement of technology and the higher demand for energy saving, the requirements for passive energy saving effects of residential buildings are also constantly increasing. Therefore, many traditional local methods used in farmhouses in severe cold regions have gradually become difficult to meet the residential requirements of rural construction in the new era. On the other hand, many prefabricated residential systems that have been maturely applied in cities face the dilemma of being difficult to promote in rural areas. For example, the construction systems such as prefabricated hollow shear wall system, modular assembly system, and prefabricated container involve large-scale hoisting equipment during the construction process, and the construction site scale and road transportation conditions in rural areas are difficult to support the application of such large equipment. This has hindered the popularization of such building systems in rural areas in severe cold regions to a certain extent. Another example is the lightweight steel structure system represented by the light steel keel system. Since it has relatively high requirements on the specifications and precision of the assembled components, and the building materials processing factories in rural areas are mostly workshop-style production by individual industrial and commercial households, their processing level is difficult to meet the various requirements of this type of building; for some remote and inconvenient rural areas, transportation from the city will increase the transportation cost significantly; local craftsmen also do not understand the construction process of this new building system very well, and often encounter problems such as inability to construct or low construction quality.

[0004] At present, the application of thermal insulation block system housing in rural areas of severe cold regions is relatively widespread. This type of building system inherits the construction characteristics of traditional masonry structures, with small components (blocks) and improved thermal insulation performance. It is used by most newly built farmhouses in severe cold regions. However, the thermal insulation block system currently used has not yet completely broken away from the masonry construction mode and the blocks are small in size. The problems of large wet work volume, complex construction process, and long construction period still exist. The problem of heat loss caused by thermal bridges in beams, columns, mortar joints and other locations in winter is still prominent. Therefore, the thermal insulation, heat storage, and thermal stability are poor. Therefore, it is particularly important to propose a prefabricated housing system with superior thermal insulation performance, low thermal bridge effect, and adaptability to rural construction and construction modes, transportation levels, and industrial production conditions, and can be quickly constructed. Summary of the invention

[0005] In order to solve the deficiencies in thermal insulation, heat storage, thermal stability, winter thermal bridge effect, etc. of existing thermal insulation block-type houses, and to solve the problems of complex construction process and long construction period, the present invention proposes a prefabricated large-scale thermal insulation block farmhouse system without thermal bridge and its assembly method.

Each component can be prefabricated in the factory, with a high degree of assembly, and is easy to transport and assemble, and has outstanding lightweight characteristics. The assembly method of the present invention greatly improves the speed of construction and greatly reduces the requirements for construction technology and construction equipment during the construction of prefabricated houses.

[0100] The method of heat storage and exchange using block walls is carried out in the following steps:

According to the heat pressure ventilation principle, the indoor hot air passes through the first top horizontal through hole (016), the fourth top horizontal through hole (034) and the third ventilation pipe (032). The air flows into the outdoor through the through hole (018) and the first ventilation pipe (023). At this time, the hot air in the room flows out, causing the air pressure at the top of the room to decrease. According to the heat pressure ventilation principle, the hot air in the lower part of the room flows toward the top of the room and flows into the outdoor through the first top horizontal through hole (016), the fourth top horizontal through hole (018) and the first ventilation pipe (023). At this time, the hot air in the room flows upward, causing the air pressure at the bottom of the room to decrease. The outdoor air pressure is greater than the air pressure at the bottom of the room. The cool air outside will flow into the room through the first bottom horizontal through hole (026), the fourth bottom horizontal through hole (034) and the third ventilation pipe (032), thereby realizing the circulation of indoor and outdoor air in summer.

At this time, outdoor sunlight shines on the sun room, and the temperature of the gas in the sun room is increased after being heated. The rising hot air increases the gas pressure at the top of the sun room. According to the principle of heat pressure ventilation, the hot air in the sun room enters the fourth top ventilation hole (019) of the upper block (9), and passes through the second ventilation pipe (024), the upper block (034) and the second ventilation pipe (024) in sequence.

After the hot gas enters the room, the air pressure in the upper space of the room increases, and the indoor cold air flows to the bottom of the room, causing the indoor bottom air pressure to increase. The indoor cold air flows into the outdoor sun room through the first bottom horizontal through hole (026), the fourth bottom horizontal through hole (034), and the third ventilation pipe (032), and rises again after being heated by the sunlight and circulates into the block wall;At night in winter, the first top horizontal through hole (016), the fourth top horizontal through hole (018), the first bottom horizontal through hole (026), the fourth bottom horizontal through hole (034), the first top ventilation hole (017) and the fourth top ventilation hole (019) are sealed by using a pipe plug (025), and the heat stored in the outer phase-change thermal insulation mortar layer (01), the inner phase-change thermal insulation mortar layer (02) and the phase-change concrete in the joint casting cavity (039) is released to the room to increase the indoor temperature. ;
