Description

Space-expandable combined house

Technical Field

The utility model relates to a mobile home technical field especially relates to a space extensible combined house.

Background

Integrated houses were born in the end of the 50 s of the last century. The method is mainly characterized in that a wall body, a roof and the like are prefabricated in a factory, a bearing structure represented by a steel structure is processed according to design requirements, and the bearing structure can be rapidly assembled into a house building mode of a complete house. The integrated house is characterized by being specially designed, standardized, modularized and generalized in production, easy to detach, convenient to install, convenient to transport and store, and capable of being repeatedly used and circulated for a plurality of times, and is temporary or permanent.

The integrated house is widely used for constructing temporary offices and dormitories of construction sites; large-scale field exploration and field operation construction rooms for traffic, water conservancy, petroleum, natural gas and the like; temporary rooms for urban office, civil arrangement, exhibition and the like; leisure villas and vacation houses in tourist areas; earthquake relief, military field and the like.

The existing integrated houses are basically divided into container houses and module box houses. The container house is a low-rise temporary house formed by transforming a second-hand container or a new container, the size of each module is fixed and equal to the size of the container, the size of each module is limited, diversification cannot be achieved, certain limitation exists, the space of the container house is relatively small, and if the size needs to be enlarged, a plurality of containers need to be combined and secondary decoration is carried out. The box transportation needs consume a large amount of spaces, and the conveying efficiency is low, and the freight cost is high. The modular box house is divided into a fixed type and a folding type, most of the modular box houses are fixed type and flexible in size change, the modular box house cannot be folded, the using area of the modular box house is limited, the on-site splicing workload can be increased relatively, and the modular box house has the similar defect as a container house; the using area of the folding type module house is increased to a certain extent compared with that of the fixed type module house, the field workload is reduced, but the folding type module house is complex in structure and high in cost. There is also an assembled house, which solves the problem of transportation efficiency, but requires a lot of time for on-site assembly and interior finishing; when the temporary building needs to be changed over for a plurality of times, the cycle of disassembling, transporting and recombining consumes a great deal of time and money, and simultaneously, the comfort level and the component quality of the house are also obviously reduced after the temporary building is disassembled and recombined for a plurality of times.
