Abstract

PURPOSE:To reduce high position works and to fix the thickness of a beam irrespective of the existence of the attaching of an outer wall. CONSTITUTION:A substrate frame 11 to which outer wall panels 5A, 5B are attached is provided, and fixed near the pillar 1 of a frame 4 or the side of pillars of beams 2A, 2B, 3A, 3B. Since the outer wall panels 5A, 5B can be previously attached to the substrate frame 11, namely the above panels 5A, 5B dispense with direct attaching to the frame 4, high position works can be reduced. Since the load of the outer wall panels 5A, 5B moreover acts on a pillar 1 or near the side of the pillars of the beams 2A, 2B, 3A, 3B through the substrate frame 11, the deflections of the beams 2A,2B, 3A, 3B can be also reduced, and the thickness of the above beams can be fixed irrespective of the existence of the attaching of the outer wall panels 5A, 5B.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit used in a unit construction method. More specifically, the present invention relates to a building unit in which columns and beams are connected to each other to form a skeleton, and exterior members such as outer wall panels, sashes, and shutters are attached to the skeleton.

[0002]

BACKGROUND ART A building unit used in a unit construction method is, as shown in FIG. 3, four pillars 1 arranged at four corners and a long side ceiling beam 2A and a short side ceiling which connect upper ends of the pillars 1 to each other. A rectangular parallelepiped skeleton 4 including a beam 2B, a long-side floor beam 3A and a short-side floor beam 3B that connect the lower ends of the columns 1 to each other.
Is configured. An exterior member, for example, an outer wall panel 5 or a sash or shutter (not shown) is attached to a surface of the skeleton 4 corresponding to the outer peripheral portion of the building,
Inner wall panels (not shown), ceiling materials, floor materials, etc. are attached to the inside.

Conventionally, since the exterior member such as the outer wall panel 5 is mounted between the upper and lower beams forming the frame 4, for example, it is previously attached to the ceiling beam 2A and the floor beam 3A to which the outer wall panel 5 is attached. Metal fittings are attached. That is, the outer wall panel 5 is provided on the lower surface of the ceiling beam 2A.
An L-shaped mounting bracket 6 for fixing the upper part of the is attached by welding or the like. Further, the floor beam 3A has an L-shaped support metal fitting 7 for supporting the lower surface of the outer wall panel 5 on the outer surface of the web, and an L-shaped metal fitting for fixing the lower portion of the outer wall panel 5 to the upper flange upper surface by a fastening metal fitting 9. The fittings 8 are attached by welding.

In the building unit production line, first, a cuboid frame 4 is formed, and then an outer wall panel 5 is attached to the frame 4. To attach the outer wall panel 5 to the skeleton 4, the outer wall panel 5 is lifted and positioned outside the skeleton 4, and then the lower surface is placed on the support fitting 7 while being hung. Therefore, the upper part of the outer wall panel 5 is screwed into the upper part of the outer wall panel 5 by bringing the bolt inserted through the mounting part 6 into close contact with the ceiling beam 2A while raising the upper part with the support metal part 7 as a fulcrum. Fix on 2A side. In addition, a fastening metal fitting 9 is held on the lower part of the inner surface of the outer wall panel 5 with a bolt, and the mounting metal fitting 8 is sandwiched between the fastening metal fitting 9 and the inner surface of the outer wall panel 5.
The lower part of the outer wall panel 5 is fixed to the floor beam 3A side.

[0005]

In the conventional building unit manufacturing line, since the outer wall panel 5 is directly attached to the frame 4 formed in a rectangular parallelepiped shape, for example, the upper portion of the outer wall panel 5 is fixed to the ceiling beam 2A side. At this time, the worker must insert the bolt through the mounting bracket 6 and screw it into the upper portion of the inner surface of the outer wall panel 5, and therefore must work at a high place using a stepladder or the like. This is not only dangerous but also difficult to work, resulting in poor work efficiency and lengthening of the production line.

Further, in the building unit manufactured in this way, the beam 2 to which the outer wall panel 5 is not attached is attached.
B, 3B, etc., since the load of the outer wall panel 5 is applied to the beams 2A, 3A to which the outer wall panel 5 is attached, in order to prevent bending or the like from occurring with respect to the load, the former It is necessary to make the latter beam thicker than the other beam. This leads to a drawback that the number of building units increases because the beam thickness must be changed depending on whether or not the outer wall panel 5 is attached.

Here, the object of the present invention is to eliminate such drawbacks of the prior art, to reduce the work at height, and to make the thickness of the beam constant regardless of whether or not the exterior member is attached. To provide a building unit.

[0008]

Therefore, in a building unit of the present invention, a pillar is connected to a beam to form a skeleton, and an exterior member is attached to the skeleton. It is characterized in that a frame is provided and the base frame is fixed near the pillar side of the frame or the pillar side of the beam.

[0009]

In the manufacturing of the building unit, after the exterior member is attached to the base frame, the base frame may be fixed near the pillar side or the pillar side of the frame, that is, directly to the three-dimensionally structured frame. Since it is not necessary to attach an exterior member, work in high places can be reduced. Moreover,
Since the load of the exterior member acts on the column of the frame or the vicinity of the column side of the beam through the base frame, the bending of the beam can be reduced and the thickness of the beam can be made constant regardless of whether the exterior member is attached or not. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the building unit of the present invention will be described in detail below with reference to FIGS. In the description of these drawings, the same components as those in FIGS. 3 and 4 described above will be denoted by the same reference numerals, and the description thereof will be omitted or simplified.

As shown in FIG. 1, the building unit of this embodiment is provided with a base frame 11 to which an exterior member such as the outer wall panel is attached. The base frame 11 is
The frame 12 has a frame body 12 having substantially the same size as the long side profile of the frame 4. The frame body 12 includes two vertical members 13 having substantially the same length as the length of the pillar 1, and two horizontal members 14 having substantially the same length as the long side ceiling beam 2A and the floor beam 3A. Is formed in a horizontally long rectangular frame shape.

As shown in FIG. 2, each of the vertical members 13 is formed of an angle member having two right-angled surfaces 21 and 22 facing the outer side surface of the column 1 and the inner side surface perpendicular to the outer side surface thereof. A fixing portion 24 for fixing the pillar 1 to the pillar 1 via a bolt 23 is burned at a vertical position of the surface 22 on one side. Supporting pieces 25 for supporting the lower surface of the outer wall panel 5 </ b> A are integrally formed at the both ends of the lower horizontal member 14 to project outward at right angles.

Inside the frame body 12, there are inserted two partition members 18 which partition the inside of the frame body 12 laterally into three surfaces 15, 16 and 17. Of the three surfaces 15, 16, 17 partitioned by the partition members 18, diagonal members 19 are obliquely inserted at diagonal positions of the surfaces 15, 17 on both sides. Note that brace or the like may be used instead of the diagonal member 19 for reinforcement.

Outer wall panels 5A are attached to the surfaces 15, 17 on both sides of the three surfaces 15, 16, 17 partitioned by the partition member 18. Outer wall panels 5B and 5B are attached to the upper and lower portions of the intermediate surface 16, respectively, and a sash 5C is attached therebetween.

In assembling, in the main manufacturing line, the long side floor beams 3A and the short side floor beams 3B are provided between the lower ends of the four pillars 1, and the long side ceiling beams 2A and the short sides are provided between the upper ends. The side ceiling beams 2B are connected to each other to form a rectangular parallelepiped skeleton 4, and the outer wall panels 5A and 5B and the satu 5C are attached to the base frame 11 in a subline different from this.

In this, the base frame 11 is placed in a horizontally lying posture, and in this posture, the surfaces 1 on both sides are placed.
The outer wall panel 5A is attached to 5, 17 and the outer wall panels 5B, 5B and the sash 5C are attached to the intermediate surface 16. In this way, the base frame 11 to which the outer wall panels 5A, 5B and the satu 5C are attached is carried into the main production line and assembled to the outside of the rectangular parallelepiped frame 4 produced in the production line.

To this end, the base frame 11 is hung up and erected vertically, and then is placed on the side face of the long side of the frame 4 in this posture. Here, the bolt 23 is screwed from the fixing portion 24 of the vertical member 13 of the base frame 11 and fixed to the pillar 1. That is, the upper and lower parts of the vertical members 13 on both sides are directly connected to the pillar 1.
The base frame 11 is fixed to the skeleton 4 by fixing to the frame 4.

Therefore, according to this embodiment, when manufacturing the building unit, the outer wall panel 5 is attached to the base frame 11.
After the A, 5B and the sash 5C are attached, the base frame 11 may be fixed to the pillar 1 of the skeleton 4, that is, the outer wall panel 5A or the like does not have to be attached directly to the skeleton 4 configured three-dimensionally. , Work at height can be reduced.

Further, this makes it possible to standardize and simplify the manufacturing line of the building unit, so that it is possible to improve the productivity and contribute to the shortening of the manufacturing line.

Moreover, since the load of the outer wall panel 5A acts on the pillar 1 of the frame 4 through the base frame 11, it is possible to reduce the bending of the beams 2A, 2B, 3A, 3B, and whether or not the outer wall panel is attached. Without beams 2A, 2B, 3
The wall thickness of A and 3B can be made constant.

In the above embodiment, the base frame 11
Was fixed to the pillar 1 of the frame 4, but the fixing position of the base frame 11 to the frame 4 is not limited to the pillar 1, but at a position where the bending of the beams 2A, 2B, 3A, 3B is reduced. I wish I had it. For example, the vertical member 13 of the base frame 11 may be fixed near the pillar 1 side of the beams 2A, 2B, 3A, 3B. Furthermore, base frame 1
One vertical member 13 for the pillar 1 and the other vertical member 13 for the beam 2
You may make it fix to the pillar 1 side vicinity of A, 2B, 3A, 3B.

In the above embodiment, the base frame 1 is fixed to the long side surface of the frame 4, but it may be fixed to the short side surface. In this case, the size of the base frame 11 may be set to a size that matches the contour shape of the mounting surface. The base frame 11 does not necessarily have to have a frame shape.

Further, the exterior member is not limited to the outer wall panels 5A, 5B and the sash 5C described in the above embodiment, but other members may be used. For example, a shutter or the like may be used.

[0024]

As described above, according to the building unit of the present invention, the base frame to which the exterior member is attached is provided, and the base frame is fixed near the column side of the frame or the beam. Since it can be attached to the base frame, that is, it is not necessary to attach the exterior member directly to the skeleton, work in high places can be reduced. Moreover, since the load of the exterior member acts on the column of the frame or the vicinity of the column side of the beam through the base frame, the bending of the beam can be reduced and the wall thickness of the beam can be made constant regardless of whether the exterior member is attached or not. it can.
