[0022]

Next, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, four corner pillars 1
The inner cylinder 1n is fitted in the outer cylinder 1g so as to extend and contract.
The ceiling beam 2 and the ceiling girder 3 are bridged over the opposing surface at the upper end of the outer cylinder 1g of the four corner columns, and the intermediate beam 4 and the intermediate girder 5 are also bridged over the lower opposing surface. The floor beam 6 and the floor girder 7 are also bridged on the surface facing the free end (lower end) of the cylinder 1n.
The ceiling beams 2, ceiling beams 3, intermediate beams 4, intermediate beams 5, floor beams 6, and floor beams 7 are also outer cylinders 2g, 3g, 4g, 5g, and 6g.
And 7g have inner cylinders 2n, 3n, 4n, 5n, 6n and 7n fitted therein so as to extend and contract.

Outer cylinder 2 of ceiling beam 2, intermediate beam 4 and floor beam 6
In g, 4g and 6g, a middle girder 10 is bridged with a gap 12 and this middle girder 10 is also attached to the outer cylinder 10g and the inner cylinder 1
0n is telescopically fitted.

The back surface of the outer cylinder of the ceiling beam 2, the ceiling girder 3, the upper and lower surfaces of the intermediate beam 4 and the outer cylinder of the intermediate girder 5, the floor beam 6, the floor girder 7
A reinforcing channel 11g is applied to the upper surface of the outer cylinder and fixed by known means such as welding.

As shown in FIG. 3, the inner cylinder 1n and the outer cylinder 1g of the column 1 are provided with a rack gear 19 attached to the inner cylinder 1n.
This is performed by driving a pinion 21 that meshes with the rack gear 19. The pinion 21 is driven by a geared motor 20 attached to the outside of the outer cylinder 1g. The keyed motor 20 can be used as an expansion / contraction drive source for other inner and outer cylinders if the mounting dimensions and structure are standardized and made detachable. Can be used.

The inner cylinder 1n and the outer cylinder 1g can be expanded and contracted not only by a rack gear and a pinion but also by a screw and a nut. In addition to the expansion and contraction of columns, the above mechanism can be used for expansion and contraction of beams and beams of a ceiling, beams and beams of an intermediate floor, and beams and beams of a floor.

Each of the inner cylinders 2n, 3n, 4n, 5n of the ceiling beam 2, ceiling beam 3, intermediate beam 4, intermediate beam 5, floor beam 6, and floor beam 7
, 6n and 7n are arbitrarily drawn out, as shown in FIG.
A screw 16 is screwed into the fixing member 7.

Inner cylinder 2 of ceiling beam 2, intermediate beam 4 and floor beam 6
Since the middle girder does not exist at the time when n, 4n, and 6n are pulled out, as shown in FIGS.
The girder 9 is fitted with the inner cylinder 9n so as to be expandable and contractible.

The middle spar 9 is provided with a fixed hook 13a at one end and a hook 13b urged in the direction of the arrow by a spring 18 around a pin 15 at the other end. 13b is a hook hole 14 of the inner cylinder 2n, 4n, 6n.
Fit into.

When the middle girder 9 is bridged over the inner cylinders 2n, 4n, 6n of the ceiling beam 2, the intermediate beam 4, and the floor beam 6, the locking hook 13b urged by the spring 18 around the pin 15 is used. The work can be easily carried out by first fitting into the hook hole 14 and then lowering the fixed hook 13a so as to fit into the hook hole 14. Conversely, when removing the middle girder 9, the procedure is reversed. After the size of the building is enlarged and adjusted at the construction site as described above, interior and exterior work is performed by known means to complete the free-size unit house according to the present invention.

Next, the embodiment shown in FIG. 2 will be described. This embodiment is based on the embodiment of FIG. 1, increases the number of constructions at the factory, reduces the number of constructions on site, adds improvements to improve the aesthetics after the construction, and expands and contracts the room, A versatile driving means for the outer cylinder is used.

The feature of this embodiment is that the lower surface line of the channel 11g applied to the back surface of the intermediate beam 4 and the intermediate girder 5 coincides with the lower end of the outer cylinder 1g of the column 1 and the column 1g When the inner cylinder 1n is extended to form the second floor, the step between the outer cylinder 1g and the inner cylinder 1n is hidden between the ceiling on the first floor and the floor on the second floor, enabling aesthetically good construction. When all the inner cylinders of pillars, beams and girders are housed in the outer cylinder and made to the minimum external dimensions, the floor and ceiling of the first floor, the floor, ceiling and roof of the second floor, In addition, the interior and exterior construction of other areas, except for the area that expands the room, can now be performed at the factory.

The channel 11g applied to the upper surface of the floor beam 6 and the floor girder 7 bridged over the lower end of the inner cylinder 1n, and the channel 11g applied to the upper surface of the intermediate beam 4 and the intermediate girder 5 have a medium. The girder 10 is bridged at a predetermined interval, the flooring of the first floor and the second floor is constructed, the lower surface of the channel 11g applied to the back surface of the intermediate beam 4 and the intermediate girder 5, and the outer cylinder 1g.
On the lower surface of the channel 11g, which is applied to the lower surface of the ceiling beam 2 and the ceiling girder 3 that is bridged over the upper part of the ceiling, the first and second floor ceilings are constructed via a crosspiece. On the upper surface of the girder 3, a middle girder 10 is hung and a roof is constructed. When constructing the floor and ceiling of the first floor, the outer cylinder 1g and the inner cylinder 1n of the pillar 1 are extended to such an extent that construction is possible,
Work is performed by placing a block between the floor beam (floor girder) and the intermediate beam (middle girder), and after completion, the inner cylinder 1n in the outer cylinder 1g is accommodated.

Following the construction of the floor, ceiling and roof, exterior and interior construction work is performed on the surface where the room is not planned to be expanded.
At this time, these exterior / interior works are the work of the second floor that will be extended, so if you extend the second floor and attach the construction panel of the first floor, the second floor will be extended. When it is done, the interior work of the first floor can be performed immediately.

When the free-size unit house according to the present invention configured as described above is to be shipped from a factory, FIG.
As shown in (1), all the inner cylinders are housed in the outer cylinder to minimize the outer dimensions, and the other three surfaces except the direction of the arrow and the floor, ceiling and roof of the first and second floors The construction has been completed and the interior panels of the first floor, which are required when the second floor is extended, are already attached.

In this state, when the truck is transported and installed at a predetermined place on a construction site, the electric jack is extended in the direction of the arrow by a dedicated electric jack, as shown in 2 of FIG. The roof, interior and exterior are constructed and 3 in Fig. 7
become that way. Here, it can be extended in the Y-axis direction, but the description is omitted because the construction contents are the same.

Next, dedicated electric jacks are arranged at the pillars at the four corners, and the jacks are operated synchronously by a control panel (not shown) to expand the second floor, as shown in FIG.
The interior and exterior work (5 in FIG. 7) is performed and completed (6 in FIG. 7).

In the description of the above embodiment, the description has been made on the assumption that the unit house can be expanded / contracted in all directions, in the depth and height directions. When required, frontage, depth and height directions only expand in two directions.
May be required to shrink. Therefore, in such a case, it is not necessary to make the columns, beams or girders in the direction not expanding or contracting a double structure.

[0039]

As described above, according to the present invention, the size of a unit house can be reduced to a size that can be transported by a normal truck without losing the advantages of the unit house, and the size can be freely changed at a construction site. The transportation cost can be reduced and the size of the house can be freely adjusted.
