Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a prefabricated house used at construction sites, event venues, temporary housing, etc., and in particular can be assembled and stored quickly. Furthermore, the present invention relates to a prefabricated house that can shorten the assembly work time and extremely reduce the storage volume when not in use.

[Conventional technology]

2. Description of the Related Art Conventionally, temporary houses used at construction sites, event venues, temporary housing, etc., have often been used as temporary houses for workers to take breaks and lodging, or as offices for giving instructions. It is customary for these temporary housing units to be temporarily assembled at a construction site, temporary location, etc., and then disassembled and removed once the purpose of use has been achieved.
For this reason, prefabricated prefabricated houses were often used.

However, these conventional prefabricated houses require a lot of effort to assemble and disassemble, making it difficult to assemble them in a short period of time for emergency purposes. In addition, the number of parts used is large, and because they are combined to form a single house, the repeatability is low, and after being used several times, parts cannot be reused and must be replaced. Otherwise, there was a drawback that it could not be used again as a prefabricated house.From this point of view, for example, Utility Model No. 52006 of 1972, Utility Model No. 55285 of 1972, Utility Model Model No. 28252 of 1973, and Utility Model Number 54 of 1972.
Prefabricated houses, such as No. 1284 of 2013, have been devised that can be used repeatedly and are easy to assemble and dismantle. However, in these newly proposed prefabricated houses, it is only possible to assemble a prefabricated house with the same size as the floor area, and it is not possible to use the floor area widely. It was difficult to do.

[Problem that the invention seeks to solve]

In conventional prefabricated houses, the parts are transported in pieces and then assembled using bolts and nuts at the installation site, or the parts are already assembled into a three-dimensional shape and then moved to the installation site using a crane, etc. To increase the floor space by storing things that are relocated and fixed, or other houses that can be pulled out inside one house, and then, after installing it at the installation location, pulling out the inner houses. Things were being thought of. As mentioned above, the method of separating the floor, wall, and roof components and assembling them on site with bolts, NANDs, and even braced reinforcing bars has been used for a long time, but as the number of parts increases, it becomes difficult to assemble. It takes a lot of time to do this, and it also takes a lot of time to remove it, so the 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 taken to assemble and dismantle the house be extremely short compared to the number of days it will be used. In addition, houses that have been preassembled in three-dimensional form are placed on trucks and set up using cranes, etc. at the construction site, but since the houses have already been assembled, the assembly and removal work is extremely difficult. Although it is quick, the floor space is limited to the size of the truck body because it transports the houses themselves, and there is also a limit to the number of houses that can be placed in the trunk, so one truck can have a large floor space. It was technically impossible to transport the prefabricated houses. 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 has also been considered to store smaller houses inside one house and extend it horizontally or vertically at the site to increase the floor space, but in this case, the transportation will be carried out twice. The total area that can be accommodated is limited to 2 to 3 times the truck bed, and it is not possible to transport houses with larger floor areas in one truck.

In addition, since the house is disassembled into multiple parts and assembled by expanding and contracting, the assembly process is extremely quick, but there is a drawback that rain, wind, etc. can enter the joints between the houses, and the construction of the house is difficult. requires precision processing,
It also had the disadvantage of being expensive. In addition, like the utility model mentioned above, there is a structure in which the side walls can be folded in the center and extended vertically, but because the side walls are folded up and down, the house can only have the same area as the floor area. However, it was technically impossible to create a large effective floor area.

Means for Solving Problem C] The present invention was made in view of the above-mentioned drawbacks, and includes a slightly flat rectangular floor section, and a floor section located above the floor section at a distance and rotatable at the center. a pair of roof parts connected to the
A pair of left floor sections and a right floor section, each of which is rotatably connected on the left and right sides of the floor section and rotatably connected at the center thereof, and a pair of left and right floor sections that are rotatably connected on the left and right sides of the roof section, respectively. a pair of left N root parts and a right roof part which are rotatably connected in the center, a central gable wall part fitted into the space between the floor part and the roof part, and a space between the left floor part and the left roof part. The left gable wall fits into the space formed between the right floor, the right roof, and the wall, and the right gable wall fits into the space formed between the right floor, right roof, and wall, and the floor and roof are vertically connected. It consists of a support pillar,
To provide an assembled house characterized in that a left roof part, a right roof part, a left floor part, a right floor part, and left and right wall parts are folded between the floor part and the N root part when stored.

[Effect]

In the present invention, during transportation, the left and right floors are folded into the central floor, the left and right walls are folded onto the folded left and right floors, and the left and right roofs are folded onto the folded walls. Finally, by placing the central roof part, the panel-shaped floor part, left and right floor parts, walls, and left and right roof parts can be folded onto the floor part of the same area. When assembling, after lifting the central roof part with a crane, etc., expand the left and right floors, left and right walls, and left and right roof parts in the left-right direction of the floor, and then Side chambers with the same floor area as the floor are formed on the left and right sides of the
It is possible to form a space approximately twice the size of the floor.

Next, the operation of this embodiment will be explained.

First, a description will be given of the work in which each member of the prefabricated house is folded from the assembled state in FIG. 1 to reduce its volume and then stored before being moved.

First, a wire is inserted into the metal fitting 17, and the wire is lifted using a crane or the like to lift the roof part 2 a little. After that, with this roof section 2 lifted, by removing the bolts from the columns 11 and corner columns 12, the floor section l, left floor section 3, right floor section 4, roof section 2, left roof section 5, and right roof section are removed. Remove from part 6. FIG. 2 shows a state in which the support column 11 and corner support column 12 are removed.

Next, pull out the panel-shaped central gable wall, married gable wall 9, right gable wall 10, respectively, and remove the floor portion 1, roof portion 2, left roof portion 3, right roof portion 4, left roof portion 5, and right roof portion. A slightly mouth-shaped opening formed by the portion 6 and the end wall portion 7 is exposed.

As a result, there is nothing on the left and right sides, and a three-dimensional shape with a hollow interior and a panel shape with a mouth-shaped cross section is formed. FIG. 3 shows a state in which the center end wall 8, the married woman wall 9, and the right end wall 10 are removed. The left floor part 3, the right floor part 4, the left roof part 5, the right roof part 6, each having a panel shape,
A hinge 20 connecting the left and right end walls 7 at the center.
21.25.26.27.28 Hinge 18.19.23.2 which is bent in half and connects each member.
4.29.30.31.32, stack the left and right floor parts 3.4 on the floor part l, and stack the left and right floor parts 3.4 on the floor part l.
The left and right flat wall parts 7 are stacked on top of each other, and the left and right roof parts 5.6 are stacked on top of the flat wall part 7. Then, the roof portion 2 is brought into close contact with the upper portions of the left and right roof portions 5.6. During this folding, the hinges 22 connecting the roof portions 2 rotate slightly to assist the panel members folded from the left and right sides to be folded easily. The state in which each panel is folded in this way is shown in FIG. Thereafter, connecting fittings 33 are screwed to the end face corners of the floor part 1 and the roof part 2, and the sides of the floor part 1 and the roof part 2 are connected, thereby fixing and storing each panel. To lift the panel in the folded state, a wire is hooked to the metal fitting 17, and the assembled house in the folded state can be transferred to a loading platform or the like by hanging it with a crane or the like.

Figure 4 shows the panels on each side folded and attached to the metal fittings 33.
This shows the state before installation.

In addition, to assemble this prefabricated house, contrary to the above, step 4 is required.
The house can be assembled at the installation site by following the steps shown in Fig. 3, Fig. 2, and Fig. 1 in this order.

C Effects of the invention] Since the present invention is configured as described above, the assembly work and disassembly work of prefabricated houses can be done more quickly than in the past.
This will help speed up work at the construction site.

In addition, when this prefabricated house is not in use, each of the panel-like members that make up the prefabricated house can be folded (folded), so the volume becomes extremely small when stored in a warehouse, etc., making it possible to store many prefabricated houses in a small warehouse. In addition, when installed, the floor can be extended to the left and right compared to the floor area, so when carried in a trunk etc., the floor area can be larger than the floor area that can be placed in the trunk. It is suitable for gathering places with a large number of people or large construction sites.
