To assemble the house, the roof panels are hoisted up by a crane, the gable walls are erected by their own weight via links, and the girder walls are then manually erected from above the floor panels to the roof panels. increase.

[Problem to be solved by the invention]

In this way, when assembling a house, all conventional systems require a crane to lift the roof panels, which not only requires the preparation of a separate crane or other work vehicle, but also requires a lot of effort in the assembly process. Become something.

In addition, the assembly cannot be completed simply by lifting the roof panels with a crane; some wall panels must be assembled by hand, which requires manpower and labor.
The work is difficult and assembly efficiency is poor.

In addition, there is a pull-out type house that can be assembled in one touch, which is stored in the inner box unit inside the outer box unit and stored at the reservation, and the inner box unit is pulled out from the outer box unit on site and removed. The inner box unit is connected to the box unit, and both units form a house, but this drawer type cannot be folded, so it takes up a lot of space when transporting or storing. will be lost.

The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, and to assemble a foldable house without the need for a working vehicle such as a crane. To provide a folding house that can be assembled and has good workability.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention has the upper and lower edges of a light metal wall panel, which can be folded vertically and inwardly, rotatably attached to each side edge of a light metal floor panel and a roof panel. The main feature is that a wall panel erecting telescopic device is removably disposed at the bottom of the house main body.

[Effect]

According to the present invention, the house main body is folded with the wall panel folded in two vertically and inwardly overlapped on the floor panel at the central portion, and the roof panel further superimposed on the wall panel. Then, by inflating a telescopic device for standing up wall panels installed inside the main body of the house, such as a balloon, the wall panel is pushed up by the balloon and stands up, and the wall panel stands up from the side of the floor panel, and the wall panel above. At the same time, the roof panels are pushed up and the house is assembled.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the folding house of the present invention. be done.

Each panel 1.2, 3.4 is made of a material such as foamed plastic sandwiched between two aluminum plates, and the frame 1a and legs 1b of the floor panel 1 are made of extruded aluminum.

The left and right wall panels 2 are composed of an upper panel 2a and a lower panel 2b that are connected by a connecting member such as a hinge, and the lower edge of the lower panel 2b is rotated by the hinge to the left and right sides of the frame la of the floor panel 1. The upper edge of the upper panel 2a is rotatably connected to the left and right sides of the roof panel 4 by the same hinge, and the upper panel 2a and the lower panel 2b are connected to each other inwardly through the connecting portion between them. It can be folded into two parts (upper and lower).

Like the left and right wall panels 2, the front and rear wall panels 3 are composed of an upper panel 3a and a lower panel 3b connected by a connecting member such as a hinge, and the lower edge of the lower panel 3b is connected to the frame 1a of the floor panel 1. Rotatably connected with hinges on the front and sides,
The upper edge of the upper panel 3a is rotatably connected to the front and rear sides of the roof panel 4 by hinges, and the upper panel 3a and the lower panel 3b are connected to each other by connecting the upper and lower panels inwardly through the connecting portion of both panels.
Can be folded and combined freely.

The lengths of the front and rear wall panels 3 in the horizontal and longitudinal directions are determined to ensure insertion space for folding the left and right wall panels 2.
A width equal to at least the height of the upper panel 2a and lower panel 2b is subtracted from the length of the floor panel 1 or the roof panel 4 in the horizontal direction on both the left and right sides. and,
In the left and right openings between the floor panel 1 and the roof panel 4, where the wall panel 3 is not installed as a folding allowance for the wall panel 2, the lower edges of the entrance/exit doors 5, 5 are attached to the front and rear edges of the floor panel l. It was mounted on a hinge so that it could rotate freely.

In the figure, 6 indicates a window provided in the upper panel 3a.

The house main body is formed as described above, and inside the house main body, for example, a balloon 7 is removed, which is positioned below the lower panel 3b of the front and rear wall panels 3 to be folded, and serves as an expansion/contraction device for raising the wall panel 3. Arranged freely.

This balloon 7 has an air pipe 8 arranged at the bottom of the floor panel 1.
One end of the air supply pipe 8 is connected to the air supply pipe 8, and the other end of the air supply pipe 8 is connected to an air supply device 9 such as a portable foot pump or cylinder, or to a muffler for taking in exhaust gas from an automobile.

Next, the assembly method will be explained.

Figures 2 and 3 show the folded state, in which the balloon 7 is deflated and placed on the floor panel 1, and the wall panels 2 and 3 are placed on the upper panels 2a and 3a.
At the connection point with the lower panels 2b and 3b, the lower panel 2 is folded inward into two parts, upper and lower, in a bellows shape, and the lower panel 2 is placed on the floor panel 1.
b and 3b are overlapped, and the upper panels 2a and 3a are overlapped on top of this, and the door 5 is also in a state of being overlapped on the floor panel 1 inside the house with the connection part with the floor panel 1 at the lower edge as an axis. .

In this state, both the left and right wall panels 2 and the front and rear wall panels 3 fall down onto the floor panel l inside the house about the joint with the floor panel 1 and protrude into the house, but the front and rear wall panels 3 Since the width of the door 5 is shorter than the length of the floor panel 1 on the left and right sides, the insertion space for folding the left and right wall panels 2 is secured, and the left and right wall panels 2 can be folded on the floor panel 1.
The front and rear wall panels 3 do not overlap.

The roof panel 4 is further superimposed on the upper surface of the wall panels 2, 3 folded onto the floor panel 1 in this manner via the pivoting portions at the upper edges of the wall panels 2, 3.

In this folded state, the house is loaded onto the bed of a truck or suspended by a helicopter and transported to the installation site.

Place the folded house at the installation site, connect the air supply device 9 to the air pipe 8 of the balloon 7, and
When air is supplied to the balloon 7, the balloon 7 is inflated by the air sent into the balloon 7.

When the balloon 7 is inflated, the lower panels 2b and 3b of the wall panel 2.3, which overlapped with the upper part of the balloon 7, are pushed upward, and the lower panels 2b and 3b are centered around the pivot point with the floor panel 1. and pivot outwardly and upwardly so that the upper panel 2a.

3a is pushed outward while rotating at the pivot joints with the lower panels 2b and 3b and the pivot joint with the roof panel 4.

As a result, the lower panels 2b, 3b and the upper panel 2a
, 3a are overlapped and folded horizontally,
The wall panels 2 and 3 stand on the sides of the floor panel 1 in a vertically continuous manner, and the wall panels 2 and 3 stand on the side of the floor panel 1.
At the same time, the roof panel 4 pushed upward is disposed (see FIGS. 4 and 5).

Next, the door 5 is pulled forward from inside the house centering on the connecting part of the lower edge with the floor panel 1, and placed side by side on the same plane as the wall panel 3, so that the lower edge of the door 5 and the floor panel 1 are aligned. Release the connection and attach it to the side edge of the wall panel 3 (Fig. 6, 7).
(see figure).

Finally, the air in the balloon 7 is removed or the balloon 7 is removed to complete the assembly (see FIGS. 1 and 8).

Such assembly work only requires supplying air to the balloon 7, and is automatically performed as the balloon 7 inflates.
In this case, the wall panels 2 and 3 and the roof panel 4 are made of lightweight materials with foamed plastic sandwiched between aluminum plates, so they can be easily lifted by air pressure.
Also, a low air pressure is sufficient.

After use, the house can be removed by reversing the assembly process described above.

〔Effect of the invention〕

As described above, the folding house of the present invention can be assembled by a person in a single touch without using a work vehicle such as a crane, and is lightweight and easy to handle, improving the workability of assembly. It is.
