Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a building unit.

[0002]

2. Description of the Related Art In a unit building, a box-shaped building unit having a fixed size, which can be transported, and finished inside and outside, and a roof unit and a roof panel are manufactured in a factory in advance. A unit that transports multiple units, roof units, and roof panels to the construction site and assembles it at the construction site to form a building.The feature of this site is that it is a standardized building with a short on-site construction period and high dimensional accuracy. Therefore, it has been widely adopted in recent years. In some cases, the roof panel is attached to a building unit in a factory and transported to a construction site.

Various types of building units are known as building units used in this unit building. For example,
In Japanese Patent Publication No. 61-42061 (hereinafter referred to as Conventional Example 1), four pillars arranged at four corners of a plane rectangular shape, and upper ends of the four pillars are connected along a rectangular side. A framework of a building unit including a ceiling beam and a floor beam connecting lower ends of the four pillars along a rectangular side is described. Then, a ceiling edge is inserted over the opposing ceiling beam, a ceiling material is attached to the lower surface of the ceiling edge, a ceiling is formed, a floor beam is inserted over the opposing floor beam, and a floor joist is mounted thereon, On the floor joists, floor materials are attached to form a floor, and in places where walls are to be provided, studs are attached between ceiling beams and floor beams, and wall panels are attached to the studs to form walls. It is a unit.

[0004] Japanese Patent Laid-Open Publication No. 6-185122 (hereinafter referred to as Conventional Example 2) describes a building unit in which a detachable pillar is provided at a corner where a pillar is omitted. This building unit is installed with the pillar omitted corners facing each other,
After connecting the ceiling beams at the corners where the pillars are omitted with a reinforcing connector, the detachable pillars are removed to form a unit building having the corners where the pillars are omitted.

Japanese Patent Application Laid-Open No. 8-277580 (hereinafter referred to as Conventional Example 3) discloses a building unit in which a detachable pillar is provided at a corner where the pillar is omitted, after the corner where the pillar is omitted is fitted to each other. , A reinforcing beam having a length approximately equal to twice the length of the ceiling beam is inserted between the ceiling beam of one building unit and the ceiling beam of the other building unit, which are substantially linear and pass through the corner where the pillar is omitted. A unit building is described in which both ends and a central portion of the unit building are connected to a ceiling beam, and a pillar omitted corner portion from which a temporary column is removed.

Japanese Patent Application Laid-Open No. H10-61021 (hereinafter referred to as Conventional Example 4) discloses that three or four building units each having a detachable pillar provided at a pillar omitted corner are provided with the pillar omitted corner. The cross-shaped reinforcing beams are installed in the cross-shaped gaps at the corners of the adjacent building units where the pillars are omitted, and these cross-shaped reinforcing beams are connected to the ceiling beams. There is described a unit building having a pillar omitted corner portion for removing a pillar. Note that one of the two cross-shaped reinforcing beams has a length substantially equal to the sum of the two straight ceiling beams that pass through the corners where the columns of the building unit are omitted.

[0007]

However, in a unit building in which a plurality of unit buildings described in the prior art 1 are assembled, there is always a column at the corner where the corners of the building unit meet, and the column is blocked by the column. There is a problem that it is not possible to form a widely continuous living space. Conventional example 2
-In the unit building described in Conventional Example 4, the above problem is solved, and by detaching a detachable pillar,
This part can form a widely continuous living space, which is extremely convenient.

However, it has been found that there are the following problems. In other words, building units are manufactured at locations other than the construction site such as factories, transported to the construction site by trucks, etc., and assembled at the construction site to form unit buildings. ing. Therefore,
In a rectangular building unit, the short side cannot be larger than the width of a truck or the like, so that the length is set to approximately 2400 mm, and the long side is a length based on the module size (900 mm or the like) of the building, for example, 3600 mm, 4500 mm, 5400 m.
The length is obtained by adding a correction part such as the thickness of the pillar to m.

[0009] In the unit building described in the prior art example 2, when the ceiling beams at the corners where the pillars are omitted are connected by the reinforcing connector, the ceiling span of the ceiling beam passing through the corners where the pillars are omitted is equal to that of the normal ceiling beam. Since the length of the ceiling beam is doubled, there is a risk that the double-length ceiling beam may be greatly bent or damaged. Therefore, the length of the ceiling beam that passes through the corner where the pillar is omitted cannot be so long, and there is a limit to the expansion of a wide continuous space where the pillar is omitted.

The reinforcing beam used in the unit building described in the prior art example 3 has a length substantially equal to twice the length of the ceiling beam. there is no problem. However, when this reinforcing beam is attached to the long side, the reinforcing beam has a length substantially equal to twice the long side (approximately 7200 mm, approximately 9000 mm, approximately 108 mm).
00 mm), which is extremely long. Therefore, there is a problem that it is difficult to transport and it is too long to attach to the long side of the building unit. When the reinforcing beam is attached to the short side, the length of the reinforcing beam is almost equal to twice the short side (about 4 times).
800 mm) and easy to carry, but the following problem arises because the ceiling span in the long side direction passing through the corner where the pillar is omitted is almost twice as long as the ceiling beam on the long side. In other words, even in the case of a building unit without pillar abbreviation corners, the ceiling beam in the long side direction is
Since it is slightly bent (this bending is within the allowable range), a ceiling beam in the short side direction reinforced with a reinforcing beam is further added thereto (the ceiling span is almost twice as large as the ceiling beam in the short side). (This bending is also within an allowable range). Therefore, there is a problem in that the bending of the pillar omitted corner portion and the bending of the long side overlap, and the ceiling beam on the long side is greatly bent, and the ceiling becomes lower as the ceiling beam exceeds the allowable range.

[0011] The length of the long side where such a problem occurs depends on the load applied to the ceiling beam on the long side and cannot show a clear dimension. When a large load is applied to the long side ceiling beam, as in
Even 600 mm may exceed the allowable range. In the normal case where a large load is not applied to the ceiling beam, almost 45
00mm may exceed the allowable range, almost 5400
In mm, almost all exceed the allowable range.

Although the thickness of the long side may be increased so that the long side is not bent, a special building unit in which the thickness of the ceiling beam for the unit building having the column omitted corner portion is increased is manufactured. In that case, there is a problem that the building unit is produced in a small amount and becomes extremely expensive.

[0013] Since the reinforcing beams used in the unit building described in the prior art example 4 are cross-shaped, the respective ceiling beams forming the corners where the pillars are omitted are reinforced, and the ceiling beams are allowed as described in the prior art example 3. Although it is extremely preferable that it does not bend as it exceeds the range, there is a problem that it is difficult to transport by a truck because the reinforcing beam has a cross shape. Even if the assembly is performed at the construction site in order to eliminate such a problem, the assembling work is difficult because the reinforcing beam is large.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a unit building in which a unit building having a pillar-eliminated corner portion is assembled and the ceiling is not lowered so as to exceed an allowable range, and a method of constructing the unit building. That is.

According to the third aspect of the present invention, at least one pair of adjacent building units having the pillar omitted corner portions straddles two opposed ceiling beams and the two ceiling beams. Since the center pillars supporting the ceiling beams are provided at positions separated from the corners where the pillars are omitted, two facing ceiling beams are simultaneously supported by the center pillars, and the two ceiling beams are separately separated by two. It is more convenient to support with the middle pillar of the book.

Further, since the ceiling beams of the building units having the pillar omitted corners are connected at the pillar omitted corners, the ceiling beams of the building units without the center pillar are replaced with the ceiling beams provided with the center pillar. The ceiling beams are connected so that they do not bend. In addition, by providing a column provided at a position distant from the corner where the pillar is omitted, in a place where it does not interfere, a large living space can be formed in the corner where the pillar is omitted.

According to the fourth aspect of the present invention, a building unit having detachable pillars provided at corners where the pillars are omitted is transported to the construction site. Therefore, the building unit has a stable structure and can be manufactured, stored and transported. No deformation or breakage.

Also, two or four building units having the pillar omitted corners are installed by abutting the pillar omitted corners, and the ceiling beams of the building units are connected at the pillar omitted corners or adjacently installed pillars. At least one pair of pillars of a building unit having an omitted corner portion is provided with a middle pillar that straddles two opposing ceiling beams and supports the two ceiling beams at a position away from the omitted corner portion. After the detachable pillars are removed, there is no pillar at the pillar omitted corner in the constructed unit building, and the pillar omitted corner is at the building unit having one or more adjacent pillar omitted corners. A center pillar is provided at a more distant position. That is, the constructed unit building has substantially the same structure as that of the third aspect of the invention. Therefore, similarly to the invention according to the third aspect, the ceiling beam is not bent, and a wide living space can be formed at the corner where the pillar is omitted.
