Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit, and can be used particularly in building a unit type building having a high floor to ceiling.

[0002]

BACKGROUND ART A unit-type building is built by combining a plurality of box-shaped units having a U-shaped cross-section with an opening at the top, which are produced in advance in a factory, at a construction site.

[0003]

By the way, in the unit type building as well, in recent years, there has been a demand for a building unit capable of forming a room having a high indoor height due to changes in lifestyle and diversification. On the other hand, the entire height of the building unit is limited due to the height limitation during transportation. Therefore, a building unit having a high indoor height cannot be transported because the height limit is touched when the building unit is transported to a construction site. In such a case, normally, a building unit within the height limit during transportation is manufactured and the pillar of the building unit is extended to increase the indoor height at the construction site, or the height of the upper and lower building units is increased. Although the height of the room is increased by interposing an intermediate unit between them, there is a problem that the site work increases.

It is an object of the present invention to provide a building unit which can be transported while clearing the height limit, can secure an indoor height dimension exceeding the height limit, and can reduce on-site work. is there.

[0005]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in a building unit constituting a unit type building, the upper portion is an opening and the height from the floor to the upper end is within the height limit during transportation. The lower part is a building unit in which the lower end of the pillar is a protrusion protruding downward from the floor by a predetermined size.

[0006]

In the building unit of the present invention as described above, the upper portion is the opening portion, and the ceiling material in the usual box-shaped unit is not provided, the height from the floor to the upper portion is increased accordingly. . In addition, the lower part of the building unit has the lower end of the pillar as a protruding part that protrudes downward from the floor part by a predetermined size.Therefore, when a plurality of building units are combined, the back surface of the floor part of the upper floor building unit is It becomes the ceiling of the story building unit, and the space between the upper part of the lower story building unit and the projecting portion of the upper story building unit becomes a continuous space, which increases the indoor height. Even if the building unit does not fit within the height limit, the lower part of the building unit has a protruding part with the lower end of the pillar protruding downwards, and this protruding part is used as a hole etc. If it is inserted, the entire height is reduced by the amount of the protrusion, so that the height restriction during transportation is not hit and the above-mentioned object is achieved.

It is designed to be joined with 10.

Further, in FIG. 2, the lower floor building unit 1A
And the upper floor building unit 1B are combined, the back surface of the floor portion 15 of the upper floor building unit 1B becomes the ceiling of the lower floor building unit 1A, and the indoor height of the lower floor building unit 1A, that is, the ceiling from the floor surface. The height L3 is the height L4 from the floor surface to the back surface of the ceiling material of the ordinary box-shaped unit and the thickness L of the ceiling material.
5 and the height L2 of the protrusion 19 of the pillar 10 of the upper floor building unit 1B
And the total height of the above, which is higher than the ceiling height L4 of a usual box-shaped unit by L5 + L2.

As shown in FIG. 5, a freight vehicle 2 on which such a building unit 1 is loaded is a small freight vehicle capable of loading one building unit 1 in this embodiment. Storage recesses 25 are provided at the four corners of the bed 25 of this lorry 2.
A is formed, and the accommodation recess 25A accommodates the protrusion 19 of the pillar 10 of the building unit 1. Therefore, since the protruding portion 19 is buried in the loading platform 25,
The height from 25 to the upper end of the building unit 1 is L1 which is the same as a normal box type unit, and is lower than the entire height L of the building unit 1 by the amount of the protrusion 19. As a result, as shown in FIG. 5, the building unit 1 has a height H that is a height limit during transportation.
It fits within.

FIG. 6 shows a unit-type building 3 constructed by combining a plurality of building units 1 as described above. When the first to fourth floor building units 1A, 1B, 1C, 1D are combined, a curtain plate 4 is provided on the side surface of the projecting portion 19 of each building unit 1A, 1B, 1C, 1D. A gap between the lower end of the outer wall 17 of the upper-floor building unit 1B and the like and the upper end of the outer wall 17 of the lower-floor building unit 1A is filled. Further, the side surface of the projecting portion 19 of the building unit 1 or the like may be used as a space for mounting the eaves 5 and the balcony 6, for example.

In this embodiment, if the lower-floor building unit 1A and the like are sequentially combined with the upper-floor building unit 1B and the like,
The floor 15 of the upper-floor building unit 1B or the like becomes the ceiling of the lower-floor building unit 1A or the like. In addition, the protruding parts of the upper floor building unit 1B, etc.
A continuous space is formed by 19 and the opening 18 of the lower floor building unit 1A, etc., and as a result, the height from the floor 15 to the ceiling, that is, the indoor height, is the indoor height of a normal box-shaped building unit. The building unit is formed higher than the height and has a sufficient ceiling height. Further, the curtain plate 4 may be attached to the side surface of the projecting portion 19 of each building unit 1A, 1B, 1C, 1D, or the eaves 5 and the balcony 6 or the like may be appropriately attached.

According to this embodiment as described above, there are the following effects. That is, the upper part of the building unit 1 is an opening
It is supposed to be 18, and there is no member corresponding to the ceiling material of a normal box-shaped building unit, so the floor section 15 to the upper end of the building unit 1 is increased by that much, and a building unit with a high indoor height Becomes

Further, when such building units 1 are stacked, the floor portion 15 of the upper-floor building unit 1B or the like becomes the ceiling portion of the lower-floor building unit 1A or the like, and the lower-floor building unit is provided from the rear surface of the floor portion 15. A space that is continuous with the opening 18 such as 1A,
As a result, the height from the floor portion 15 to the ceiling, that is, the indoor height is formed to be higher than the indoor height of a normal box-shaped building unit, and the unit-type building 3 having a room with a sufficient ceiling height is provided.
Can be

Further, when the building unit 1 is transported by the truck 2, the projecting portion 19 of the building unit 1 is housed in the storage recess 25A of the luggage carrier 25, so that the upper end position of the unit 1 is as much as the projecting portion 19. As a result of the lowering, the building unit 1 falls within the height H of the height limit during transportation, and the indoor height is
The building unit can be easily transported while keeping the room height higher than that of a normal box-shaped building unit.

Furthermore, when the building unit 1 is transported by a lorry 2, the projecting portions 19 of the pillars 10 of the unit 1 are attached to the luggage carrier.
Since it is stored in the storage recess 25A of 25, the unit 1 is prevented from shifting laterally and can be transported in a stable posture.

Further, when a plurality of building units 1 are combined vertically, a curtain board is provided in a gap formed between the lower end of the outer wall 17 of the upper floor building unit 1B and the like and the upper end of the outer wall 17 of the lower floor building unit 1A. Since the 4, 4, the eaves 5, the balcony 6, etc. can be attached, for example, the work of notching a part of the outer wall for attaching them becomes unnecessary.

Further, even if the floor beam 13 of the upper-floor building unit 1B or the like is made thicker, a sufficient indoor height can be secured, and since the floor beam 13 is thick, its strength becomes large. It can also be used when building medium- and high-rise unit-type buildings with more than one story.

Further, the upper and lower floor building units 1B and 1A are joined by inserting the projecting portion 19 of the pillar 10 of the upper floor building unit 1B into the recess 22 formed in the upper portion of the lower floor building unit 1A, Since it only has to be fastened with bolts 24, joining can be done easily,
Work time can be shortened.

The present invention is not limited to the above-mentioned embodiment, but includes the following modifications. That is, in the above-described embodiment, when the building unit 1 is transported by the truck 2, the projecting portion 19 of the pillar 10 of the unit 1 is stored in the storage recess 25A of the luggage carrier 25. Since it only needs to be within the height H of the height limit at the time, the height of the loading platform may be lowered and the protrusion 19 may be placed directly on the loading platform.

Further, in the above embodiment, when the building unit 1 of this embodiment is combined with a plurality of other building units, a unit of the same type, that is, an H-shaped building unit 1
However, the present invention is not limited to this, and for example, the H-shaped building unit 1 may be placed on a normal box-shaped unit and combined. By doing so, a space is provided between the lower surface of the floor portion 15 of the H-shaped building unit 1 and the upper surface of the ceiling material of the box-shaped unit, so that the space is used in the H-shaped building unit 1, for example, This has the effect of making it easier to pass through piping and the like.

In addition, the specific structure, shape, and the like for carrying out the present invention may be any other structure as long as the object of the present invention can be achieved.
