Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a rectangular frame having columns upright at four corners and beams interconnecting the upper and lower ends of these columns. A plurality of combined building units, and a hut panel formed in a rectangular frame shape with beams, on the upper floor of the building unit, and a hut unit provided adjacent to the building unit arranged on the upper floor The present invention relates to a unit-type building having a boundary wall in which a beam is housed at the same plane position as an outer wall of an upper-floor building unit in a lower-floor building unit.

[0002]

2. Description of the Related Art Conventionally, unit-type buildings formed by combining a plurality of building units manufactured in a factory at a building site have been used. The building unit is usually composed of pillars erected at the four corners, and ceiling beams and floor beams interconnecting the upper and lower ends of these pillars, and has long sides and short sides having different lengths. It has a rectangular parallelepiped frame having a rectangular planar shape. Floor materials, wall materials, and other necessary equipment members are attached to this framework in advance at a factory. According to such a unit-type building, a floor surface material or the like is attached to the building unit in advance. Therefore, there is an advantage that the construction period at the construction site can be significantly reduced.

When such a unit-type building is used as an apartment house having a plurality of dwelling units therein, a boundary wall having fire resistance is provided at a boundary portion between adjacent dwelling units. Here, the partition wall is formed by assembling a partition wall panel forming a partition wall to a building unit at a factory (see Japanese Patent Application Laid-Open No. 8-177125).

[0004]

In such a unit-type building, when a partition wall is formed between the building units, if a partition wall panel or the like is assembled to the building unit at a factory, the pillar or beam portion of the building unit is required. Is covered with the boundary wall panel, so there is a problem that the work of joining the building units vertically and horizontally at the construction site becomes complicated.
Wall panels are installed on site. Therefore, there is a demand for a structure that can easily form a boundary wall at a construction site.

An object of the present invention is to provide a unit-type building in which a boundary wall can be easily formed at a construction site.

[0006]

The present invention will be described with reference to the accompanying drawings. Referring to the drawings, columns 12 erected at four corners and beams connecting the upper ends and lower ends of these columns 12 to each other (for example, A plurality of building units 10, 20, and 30 having a rectangular parallelepiped frame 11 having a ceiling beam 13 and a floor beam 14) and vertically and horizontally combined, and a beam 4 formed in a square frame shape
A building unit 20 having a hut panel 41 made of 1A
And a hut unit 40 provided on the upper floor and adjacent to the building unit 30 disposed on the upper floor, and the same as the outer wall 31 of the upper floor building unit 30 in the lower floor building unit 20. A unit-type building 1 in which a boundary wall 50 in which a beam is stored is provided in a plane position, and a wall material (for example, first wall) forming a boundary wall (for example, a first upper-lower boundary wall 51). Hut side wall surface material 51A, 1st
The gap between the third-floor side wall panel 51B) and the housed beams (for example, the beam 41A, the short side floor beam 14B, and the short side ceiling beam 13B) and the space between the housed beams are flexible. Characterized by being filled with a soft refractory material (for example, rock wool 63) having Here, as the outer wall,
An exterior surface material disposed on the outdoor side and an interior surface material disposed on the indoor side can be employed, and as a hut unit, for example, a roof is provided above. A hut can be used. According to the present invention, even if a fire flame enters the inside of the boundary wall, the beams and the filled soft refractory material prevent entry into the upper floor. As a result, the outer wall of the upper-floor building unit only needs to have fireproofing on the exterior facing material alone, so that a normal exterior wall structure can be adopted, and the interior facing material placed on the indoor side can be adopted. Need not be provided with the same fire protection as the barrier wall. And since such a structure of a boundary wall can be easily formed by filling a soft refractory material between beams and the like, it is possible to easily form the boundary wall at a building site. Become.

In the above description, the hut unit 40 and the lower-floor building unit (for example, the second-floor building unit 20B) side of the wall material (for example, the first hut side wall material 51A, the first third-floor side wall material 51B). The lower end of the wall material (for example, the first hut side wall surface material 51A) is attached to the beam of the lower-floor building unit (for example, the short side ceiling beam 13B), and the upper end is the beam 41A of the hut unit 40.
Of the shed unit 40
It is preferable that the outer wall 31 is in contact with a fireproof member (for example, a lightweight cellular concrete plate 42) provided on the peripheral edge of the outer wall 31. In this way, by attaching the wall material to the beams of the lower-floor building unit, it becomes possible to easily form the boundary wall at the same plane position as the outer wall of the upper-floor building unit,
Thereby, it becomes possible to easily form the boundary wall at the construction site. In addition, since the upper end of the wall material is in contact with the fire prevention member, it is difficult for flames such as a fire to enter the inside of the boundary wall, thereby making it possible to further prevent entry into the upper floor.

Further, the above-described fire prevention member includes a shed panel 41.
It is desirable to be formed of a nonflammable face material that is disposed horizontally on top. This makes it possible to block the upper part of the lower-floor building unit.
Even if a fire flame enters the inside of the boundary wall, it is possible to reliably prevent the fire from spreading to the upper floor of the hut unit or the like.

[0009] Furthermore, the boundary wall (for example, the lower floor building unit) of the second lower floor building unit (for example, the first floor building unit 10) which forms the lower floor of the lower floor building unit (for example, the second floor building unit 20). , First upper and lower boundary wall 5
In the same plane position as 1), a boundary wall (for example, a second upper and lower boundary wall 52) in which a beam is housed is provided, and a wall material (for example, a second hut side wall surface material) forming the boundary wall is provided. 52A, the second third-floor side wall panel 52B) and the stored beams (for example,
The gap between the short side floor beam 14B and the short side ceiling beam 13B) and the gap between the stored beams may be filled with a soft refractory material having flexibility (for example, rock wool 63). preferable. In this way, even if a fire flame enters the inside of the boundary wall, the beams and the filled soft refractory material prevent entry into the upper floor. This makes it possible to easily improve the fire protection performance from the second lower building unit to the roof.

In addition, the aforementioned beams (for example, the short side floor beams 14)
B, the short side ceiling beam 13B) is formed in a U-shaped cross section with one side opened, and the wall material (for example, the first hut side wall surface material 51A, the first third floor side wall surface material 51B, the second hut). The side wall surface material 52A and the second third floor side wall material 52B) are desirably attached to the beam via a bracket 61 for closing the opening of the beam and a base material 62 fixed to the bracket 61. In this case, the wall material may be fixed to the bracket by nailing or the like via the base material, so that the wall material can be easily attached to the beam, and the formation of the boundary wall is further improved. Further, the wall material is supported by the beam, the bracket, and the base material, so that the support strength of the wall material can be improved.

Further, the brackets 61 may be formed in pieces so that a plurality of them can be attached at predetermined intervals along the longitudinal direction of the beams (for example, the short side floor beam 14B and the short side ceiling beam 13B). preferable. In this way, the weight of the building unit can be reduced, and the cost of the bracket and thus the cost of the building unit can be reduced. In addition, when filling the inside of the beam with a soft refractory material such as rock wool, it is possible to easily fill the space from between the brackets, thereby facilitating the work of filling the inside of the beam with the soft refractory material.

The above-mentioned bracket 61 is desirably formed long so as to be attachable over the entire length of the beam (for example, the short side floor beam 14B and the short side ceiling beam 13B) along the longitudinal direction. . In this way, since the opening is closed over the entire length of the beam, it is possible to attach the wall material at an arbitrary position, thereby simplifying the work of fixing the wall material, and It is possible to easily and strongly reinforce.

As described above, according to the unit-type building of the present invention, the following effects can be obtained. That is, according to the unit-type building of the first aspect, even if a fire flame enters the inside of the boundary wall, the beams and the filled soft refractory material prevent entry into the upper floor. As a result, the outer wall of the upper-floor building unit only needs to have fireproofing on the exterior facing material only, so that a normal exterior wall structure can be adopted, and the interior facing surface material arranged on the indoor side can be used. It is not necessary to provide the same fire protection as the partition wall. Since the structure of such a boundary wall can be easily formed by filling a soft refractory material between the beams and the like, the boundary wall can be easily formed at a building site.

According to the unit-type building of the second aspect, by attaching the wall material to the beam of the lower-floor building unit, the boundary wall can be easily formed at the same plane position as the outer wall of the upper-floor building unit. Accordingly, the boundary wall can be easily formed at the construction site. In addition, since the upper end of the wall member is in contact with the fire prevention member, flames such as a fire are unlikely to enter the inside of the boundary wall, thereby making it possible to further prevent entry into the upper floor.

Further, according to the unit-type building according to the third aspect, since the upper part of the lower-floor building unit can be closed, even if a fire flame enters the inside of the partition wall, It is possible to reliably prevent the fire from spreading to the upper floor of the hut unit or the like.

According to the unit-type building of the fourth aspect, even if a fire flame enters the inside of the boundary wall, the beams and the filled soft refractory material prevent entry into the upper floor. Is done. Thereby, the fire prevention performance from the second lower building unit to the roof can be easily improved.

Further, according to the unit-type building according to the fifth aspect, the wall material may be fixed to the bracket via the base material by nailing or the like, so that the wall material can be easily attached to the beam. As a result, the formation of the boundary wall is further facilitated, and the wall material is supported by the beam, the bracket, and the base material, so that the supporting strength of the wall material can be improved.

Further, according to the unit-type building according to the sixth aspect, the weight of the building unit can be reduced, and the cost of the bracket and thus the cost of the building unit can be reduced. In addition, when the inside of the beam is filled with a soft refractory material such as rock wool, the filling can be easily performed from between the brackets, thereby facilitating the work of filling the inside of the beam with the soft refractory material.

Further, according to the unit-type building according to the seventh aspect, the opening is closed over the entire length of the beam.
