Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for assembling a prefabricated house used at construction sites, event halls, temporary housing, etc., and which does not require special tools. The present invention relates to a method that allows easy assembly work.

[Conventional technology]

BACKGROUND OF THE INVENTION Conventionally, simple temporary houses have often been used as offices for resting, lodging, or directing workers in temporary houses used at construction sites, event venues, temporary housing, and the like. These temporary houses are usually assembled temporarily at a construction site, temporary location, etc., and then disassembled and removed once the purpose of use is achieved, and for this reason, prefabricated assembled houses are often used. It was getting worse. However, since these conventional prefabricated houses require time and effort to assemble and disassemble, it has been difficult to assemble them in a short time for emergency use. In addition, there are a large number of parts used, and because they are combined to form a single house, the reusability of the parts is low, and after being used several times, parts may become unusable and have to be replaced. Another drawback was that it could not be used again as a prefabricated house.

Due to these drawbacks, for example, Utility Model No. 006 of 1972, Utility Model No. 55285 of 1972, Utility Model Model No. 28252 of 1973, Utility Model No. 1284 of 1972, etc., have been designed to be reusable and easy to assemble and dismantle. Houses have also been proposed.

However, in these newly proposed prefabricated houses, only the prefabricated houses with the same size as the floor area can be used when assembled; For this reason, we connected the foldable floor, roof, and walls that can be expanded and extended horizontally on the left and right sides of each floor and roof, and finally folded them. It is also possible to expand the floor space by extending the parts.However, connecting these folding parts requires special tools and special techniques for assembly work. However, it also had the disadvantage that assembly and dismantling operations were not quick enough.

[Problem that the invention seeks to solve]

In conventional prefabricated houses, the parts are transported in pieces and assembled with bolts and bolts at the installation site, or they are already assembled into a three-dimensional shape and then transferred and fixed using a crane, etc. at the installation site. thing,
Alternatively, it was considered that other houses that could be pulled out could be stored inside one house, and after the house was installed at the installation location, the floor space could be increased by pulling out the house inside. . As mentioned above, the method of separating the floor, wall, and roof components and assembling them on site with bolts, nuts, and even reinforcing bars has been used for a long time, but this method requires a large number of parts (and takes time to assemble). It takes a lot of time, and it also takes time to remove it.
Workability is extremely poor. From this point of view, for example, there is an inconvenience that it takes about the same amount of time to assemble and disassemble the house compared to the number of days it will be used, and it is desirable that the time required to assemble and dismantle the house be extremely short compared to the number of days it will be used. Ta. In addition, houses that have been preassembled in three-dimensional form are placed on trucks and installed using cranes, etc. at the construction site, but since the houses are already assembled, the assembly and removal work is difficult. Although it is extremely fast, the floor space for transporting the houses themselves is limited by the size of the trunk, and there is also a limit to the number of houses that can be loaded on the truck, so one trunk can carry a large floor space. It was technically impossible to transport prefabricated houses on the area. For this reason, if it is not possible to transport an assembled house with a floor area much larger than the floor area of the trunk in one transport, the cost of transport will be extremely high in actual operation. It is also possible to store smaller houses inside one house and extend them horizontally or vertically at the site to increase the floor space. The floor area is limited to two to three times the cargo area of the trunk, and it was not possible to transport houses with larger floor areas in one truck. In addition, the house can be disassembled into multiple parts and then reassembled by expanding and contracting, which makes the work extremely quick, but it has the disadvantage that rain, wind, etc. can enter at the joints between the houses. Precise machining was required for building houses, and it also had the disadvantage of being expensive. For this reason, the left and right floor sections, roof sections, and walls that can be folded on both sides of the basic floor section and roof section are rotatably connected with hinges, etc., and the left and right floor sections, roof section ,
There is also a structure in which the side parts are folded between the basic floor part and the roof part, but since the connections between the left and right floor parts, roof part, and side parts are rotatable, it is difficult to assemble. Therefore, it was difficult to easily expand the left and right spaces from the basic space between the floor and roof.

[Means to solve the problem]

The present invention has been developed in view of the above-mentioned drawbacks, and has a slightly flat rectangular floor section, a roof section located above the floor section at a distance, and a rotatable connection between the left and right sides of the floor section. a pair of left floor sections and a right floor section, each of which is rotatably connected at the center, and a pair of left and right floor sections, each of which is rotatably connected at the left and right of the roof section, and whose center is rotatably connected. A left roof part and a right Mm part, a pair of wall parts each rotatably connected between the left roof part and the right floor part, and a rotatable part between the right roof part and the right floor part. In a prefabricated house consisting of a pair of walls connected to each other and rotatably connected at the center, there is a left roof part and a right roof part between the floor part and the roof part, and furthermore, a left floor part and a right floor part. The walls are folded and stored, and when lifting the Wa section, the rotation of both walls is restricted using removable fixtures, and the left and right roof sections and the left and right floor sections are extended and enlarged in turn to the left and right. The present invention provides a method for assembling a house, which is characterized by:

[Effect]

In the present invention, when transported or when not needed, the left and right floor sections, the roof section, and the side sections can be folded onto the center floor section, and the center roof section can be placed above the folded sections to shrink the volume. When in use, the space can be expanded on both sides of the central floor and roof. When assembling this house, we use auxiliary tools to temporarily restrict the rotation of the left and right floors, roofs, and walls, and then move the roof up and down to gradually open up the left and right spaces. It is something that can be expanded.
