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, A floor material is attached to the floor joist to form a floor, a stud is attached between the ceiling beam and the floor beam, and a wall panel is attached to the stud to form a wall to form a building unit.

Japanese Patent Application Laid-Open No. 6-185122 (hereinafter referred to as Conventional Example 2) discloses that a building unit having a temporary pillar provided at a corner where a pillar is omitted is installed by abutting the corners where the pillar is omitted, and the pillar is omitted. A unit building having a pillar-eliminated corner in which a temporary beam is removed after connecting a corner ceiling beam with one reinforcing connector is described.

Japanese Patent Application Laid-Open No. Hei 8-277580 (hereinafter referred to as Conventional Example 3) discloses that a building unit having a temporary pillar provided at a corner where the pillar is omitted is installed after the corners where the pillar is omitted are abutted against each other. A reinforcing beam having a length almost twice as long as the ceiling beam is inserted between the ceiling beam of one building unit and the ceiling beam of the other building unit passing through the straight corner of the pillar, and both ends of the reinforcing beam Connect the part and the center part to the ceiling beam,
A unit building having a pillar omission corner from which a temporary pillar has been removed is described.

Japanese Patent Laid-Open Publication No. Hei 10-61021 (hereinafter referred to as Conventional Example 4) discloses that three or four building units having provisional pillars provided at corners where pillars are omitted are connected to corners where pillars are omitted. A cross-shaped reinforcing beam is installed in the gap at the corner of the adjacent building unit where the cross is omitted, and the cross-shaped reinforcing beam is connected to the ceiling beam, and the temporary column is removed. A unit building with a truncated corner is described. 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.

[0008] The unit buildings described in Conventional Examples 2 to 4 solve the above-mentioned problem. By removing the temporary columns, a wide continuous living space can be formed in this portion, which is extremely convenient. It is. However, the following problems were found.

That is, the building unit is manufactured at a place other than the construction site such as a factory, transported to the construction site by truck, etc., and assembled at the construction site to form a unit building. It is becoming.
Therefore, in a rectangular building unit, the short side cannot be made larger than the width of a truck or the like.
The long side is a length based on the module size of the building (900 mm or the like), for example, 3600 mm, 4500 mm, 54
A length obtained by adding a correction portion such as the thickness of a pillar to 00 mm (hereinafter, approximately 3600 mm, approximately 4500 mm, approximately 5400 m
m).

[0010] 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 for the unit building described in the prior art example 3 has a length substantially equal to twice the ceiling beam, so that the entire ceiling beam is reinforced, and the problem described in the prior art example 2 does not occur. However, when attaching this reinforcing beam to the long side,
The length of the reinforcing beam is almost equal to twice the long side (approximately 7200m
m, approximately 9000 mm, approximately 10800 mm), which makes it extremely difficult to carry the device, and is too long to be attached to the long side of the building unit. When the reinforcing beam is attached to the short side, the reinforcing beam has a length substantially equal to twice the short side (approximately 4800 mm) and is easy to carry. Since the span is almost twice as long as the long side ceiling beam, the following problem occurs.
In other words, even in the case of a building unit having no pillar elimination corner, the ceiling beam in the long side direction is slightly bent (this bending is within an allowable range), and is further reinforced with a reinforcing beam thereon. The ceiling beam in the short side direction also has a ceiling span almost twice as large as that of the short side ceiling beam, and is slightly bent (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.

The length of the long side in which such a problem occurs depends on the load applied to the ceiling beam on the long side, and cannot exhibit 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. In addition, the thickness of the long side may be increased so that the long side is not bent,
When it comes to manufacturing a special building unit with a thicker ceiling beam for a unit building with this pillar omitted corner,
There is a problem that the building units are produced in small quantities and become 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 reinforcing beam can be easily transported and the ceiling of which does not become lower than an allowable range.

[0015]

Means for Solving the Problems The present invention has been made to achieve the above object, and the invention according to claim 1 has a structure in which columns, floor beams, and ceiling beams are formed into a rectangular box shape. Concatenate,
Further, in the unit building in which two to four building units each having a pillar-abbreviated corner in which a pillar is omitted in one corner of the rectangular shape are installed with their long sides facing each other and the pillar-abbreviated corners abutting each other, In the building unit with the long sides facing each other, the ceiling beam on the short side of one building unit and the ceiling beam on the short side of the other building unit that pass through the pillar oval corner that is almost straight, A reinforcing beam with a length approximately equal to the sum of the lengths of both short sides is inserted across and attached,
At least one of the 2 to 4 building units has another reinforcing beam of a length substantially equal to the long side attached to the long side ceiling beam forming the column omitted corner portion. is there.

According to a second aspect of the present invention, the column, the floor beam, and the ceiling beam are connected to each other in a box shape having a rectangular shape in a plane, and the rectangular shape has a pillar omitted corner portion in which the pillar is omitted in one corner. In a unit building in which four building units are installed with their long sides facing each other and the pillar omitted corners are abutted against each other, the two to four building units are large building units having different long side lengths. The building unit, which is composed of two types of small building units and whose long sides are opposed to each other, includes a ceiling beam on the short side of one building unit and a building on the other side which pass through a substantially straight pillar-abbreviated corner. A reinforcing beam with a length almost equal to the sum of the lengths of the two short sides is attached to the ceiling beam on the short side of the unit, and attached to the large building unit.
Another reinforcing beam having a length substantially equal to the long side of the large building unit is attached to the long side ceiling beam forming the column omitted corner portion.

According to a third aspect of the present invention, the column, the floor beam, and the ceiling beam are connected to each other in a box shape having a rectangular shape in a plane, and each of the rectangular shapes has a pillar omitted corner portion in which the pillar is omitted in one corner. In a unit building in which four building units are installed with their long sides facing each other and the pillar omitted corners are abutted against each other, the two to four building units are large building units having different long side lengths. The building unit, which is composed of two types of small building units and whose long sides are opposed to each other, includes a ceiling beam on the short side of one building unit and a building on the other side which pass through a substantially straight pillar-abbreviated corner. A reinforcing beam with a length approximately equal to the sum of the lengths of the two short sides is attached to the ceiling beam on the short side of the unit and attached, and the column omitted corners of both the large building unit and the small building unit Make up the long side of the ceiling beam almost equal to the long side Another reinforcing beams have a length in which is mounted.

Another reinforcing beam according to any one of claims 1 to 3 is only required to reinforce the long side ceiling beam, and is not connected to the short side reinforcing beam.

According to a fourth aspect of the present invention, the column, the floor beam and the ceiling beam are connected to each other in a plane rectangular box shape, and each of the rectangular shapes has a pillar omitted corner portion in which the pillar is omitted in one corner. In a unit building in which four building units are installed with their long sides facing each other and the pillar omitted corners are abutted against each other, the building units whose long sides face each other have pillars that are substantially linear. A reinforcing beam with a length approximately equal to the sum of the lengths of the two short sides is inserted between the short side ceiling beam of one building unit and the short side ceiling beam of the other building unit that passes through the omitted corner. At least one building unit of the 2 to 4 building units is provided with another reinforcing beam having a length substantially equal to the long side of the long side ceiling beam forming the pillar omitted corner portion, Attached to the reinforcement beam, with or without connection The short-side ceiling beam of one building unit and the short-side ceiling beam of the other building unit that pass through the substantially straight pillar omitted corner are rigidly joined at the pillar omitted corner. It is. In the invention according to claim 4, when the ceiling beam of the building unit having the column omitted corner portion requires further mechanical strength, the ceiling beam is rigidly connected and the reinforcing beam is rigidly connected to another reinforcing beam. It is good to join.

(Function) The invention according to claim 1 is characterized in that a short side ceiling beam of one building unit and a short side ceiling beam of the other building unit pass through a substantially straight pillar-eliminated corner. In addition, a reinforcing beam having a length substantially equal to the sum of the lengths of the two short sides is inserted and attached. Ceiling beams are reinforced and difficult to bend, and even if bent, the ceiling span is almost equal to the sum of the lengths of the ceiling beams on both short sides,
Not too long and within acceptable limits. In addition, since this reinforcing beam has a length substantially equal to the sum of the lengths of the ceiling beams on both short sides, it can be easily transported to the construction site.

In addition, since another reinforcing beam having a length substantially equal to the long side is attached to the ceiling beam on the long side constituting the column omitted corner portion, this long side does not bend. Therefore, even if the ceiling beam in the short side direction passing through the column omitted corner is bent to the extent that it falls within the allowable range, the ceiling does not become lower enough to exceed the allowable range. In addition, since this other reinforcing beam has substantially the same length as the long side ceiling beam, it can be easily transported to the construction site. As described above, the reinforcing beam and another reinforcing beam are easily transported, and it is not necessary to assemble the reinforcing beam at the construction site.

According to the second aspect of the present invention, the two to four building units are composed of two types, a large building unit and a small building unit having different long sides. That is, there are two types of building units: a small building unit having a long side approximately equal to 3600 mm, for example, and a large building unit having a long side approximately equal to 5400 mm for example.

In the same manner as in the first aspect of the present invention, the short side ceiling beam of one building unit and the short side ceiling beam of the other building unit pass through the substantially straight pillar omitted corner. Since a reinforcing beam having a length substantially equal to the sum of the lengths of the two short sides is installed across the short side, the short side including the pillar omitted corner is reinforced and hardly bent, and is bent. Even so, the ceiling span is almost equal to the sum of the lengths of the ceiling beams on both short sides, is not so long, and falls within the allowable range.

Further, in the large building unit, another reinforcing beam having a length substantially equal to the long side of the large building unit is attached to the long side ceiling beam forming the column omitted corner portion. In addition, the long side of the large building unit which is easily bent does not bend. Therefore, even if the ceiling beam in the short side direction passing through the column omitted corner is bent to the extent that it falls within the allowable range, the ceiling does not become lower enough to exceed the allowable range.

According to the second aspect of the present invention, the ceiling beam on the long side of the small building unit may be reinforced,
It does not need to be reinforced. In other words, when the ceiling beam on the long side of this small building unit is short, for example, approximately 3600 mm, and when a large load is not applied and it is difficult to bend, it is not necessary to reinforce. In addition, this reinforcing beam and another reinforcing beam are easily transported to the construction site, and there is no need to assemble the reinforcing beam at the construction site.

According to a third aspect of the present invention, as in the second aspect, the building units are composed of two types of large building units and small building units having different long sides. The sum of the lengths of the two short sides is almost equal to the short side ceiling beam of one building unit and the short side ceiling beam of the other building unit that pass through the substantially straight pillar omitted corner. Since the reinforcing beams having the same length are installed across the space, the ceiling beam in the short side direction including the corners where the pillars are omitted is reinforced, as described in the operation section of the second aspect of the present invention. The ceiling span is almost equal to the sum of the lengths of the ceiling beams on both short sides, is not so long, and falls within an allowable range. In addition, since this reinforcing beam has a length substantially equal to the sum of the lengths of the ceiling beams on both short sides, it can be easily transported to the construction site.

In addition, since another reinforcing beam having a length substantially equal to the long side is attached to the long side ceiling beam forming the pillar omitted corner portion of both the large building unit and the small building unit,
The ceiling beams in the long side direction of the large building units and the small building units, that is, the ceiling beams in the long side direction of all the building units are not bent. Therefore, even if the ceiling beam in the short side direction is bent to the extent that it falls within the allowable range, the ceiling does not become lower enough to exceed the allowable range. In addition, since this other reinforcing beam has substantially the same length as the long side ceiling beam, it can be easily transported to the construction site. As described above, the reinforcing beam and another reinforcing beam are easily transported, and it is not necessary to assemble the reinforcing beam at the construction site.

According to a fourth aspect of the present invention, the ceiling beam on the short side of one building unit and the ceiling beam on the short side of the other building unit that pass through the substantially straight pillar-eliminated corner are:
Since the beam is rigidly connected at the corner where the column is omitted, the strength of the beam in the short side direction passing through the corner where the column is omitted is the same as the ceiling beam on the short side of one building unit and the ceiling beam on the short side of the other building unit. Are rigidly joined together with the strength of the reinforcing beam to the strength of the beam integrated in series, and the deflection is extremely reduced as compared with the case where both ceiling beams are not rigidly joined. In the invention according to claim 4, when the ceiling beam is rigidly connected and the reinforcing beam is rigidly connected to another reinforcing beam, the mechanical strength of the ceiling beam is further increased.

Even if the ceiling beam in the short side direction passing through the omitted corner is bent to be within the allowable range, the ceiling does not become lower enough to exceed the allowable range. In addition, this reinforcing beam and another reinforcing beam are easily transported to the construction site, there is no need to assemble the reinforcement beam at the construction site, and the number of on-site construction steps does not increase.

According to a third aspect of the present invention, similarly to the second aspect, the building units are composed of two types of large building units and small building units having different long sides, and the long sides are opposed to each other. Of the short side ceiling beam of one building unit and the short side ceiling beam of the other building unit passing through the almost straight pillar corners of the building unit Since a reinforcing beam having a length substantially equal to the sum is provided across and attached, the bending of the ceiling beam in the short side direction passing through the corner where the pillar is omitted is within an allowable range.

In addition, since another reinforcing beam having a length substantially equal to the long side is attached to the long side ceiling beam forming the pillar omitted corner portion of both the large building unit and the small building unit,
Even if the ceiling beam in the short side direction is deflected to the extent that it falls within the allowable range, the ceiling does not drop below the allowable range. Also, this reinforcing beam is almost equal to twice the length of the ceiling beam on the short side, and another reinforcing beam is almost the same length as the ceiling beam on the long side. There is no need to assemble beams, and the number of on-site construction steps does not increase.

According to the fourth aspect of the present invention, the ceiling beam on the short side of one building unit and the ceiling beam on the short side of the other building unit are butted and rigidly joined at the corner where the column is omitted. The strength of the beam in the short side direction passing through the omitted corner is
The strength of the reinforcing beams is added to the strength of the butted beams that are integrated in series, and the bending is extremely reduced as compared with the case where the beams are not rigidly joined. In the invention of claim 4, when the ceiling beam is rigidly joined and the reinforcing beam is rigidly joined to another reinforcing beam, the mechanical strength of the ceiling beam is further increased.
