Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit-type building formed by connecting a plurality of box-shaped building units and a method for constructing the unit-type building.

[0002]

BACKGROUND ART Conventionally, a unit-type building constructed by connecting a plurality of box-shaped building units manufactured in a factory at a construction site has been used. As a building unit forming this unit-type building, it is common to have a box-shaped frame in which upper and lower ends of columns at four corners are connected by ceiling beams and floor beams. For the frame, the ceiling surface material supported by the ceiling beams, the floor surface material supported by the floor beams, interior materials such as partition walls for partitioning the room, and exterior materials such as outer walls made of lightweight cellular concrete are used in the factory. It is assembled in. According to such a unit-type building, it is only necessary to carry out the work of attaching interior materials and outer wall materials to the box-shaped frame in the factory to manufacture building units, and then transport these building units to the site for connection work. Since the building is completed, the work on the construction site is significantly reduced, and the construction work can be completed in a short period of time.

In the unit type building as described above, there are cases where the customer desires an atrium space. The blow-through space is formed, for example, by vertically stacking building units and providing an opening at approximately the center of the ceiling surface of the lower building unit and approximately at the center of the floor surface of the upper building unit. By doing so, it is only necessary to provide an opening at approximately the center of each of the ceiling surface of the lower building unit and the floor surface of the upper building unit. A blow-through space can be easily formed without lowering the strength (Japanese Patent Laid-Open No. 10-280547).
(See the official gazette).

[0004]

When a customer desires a larger space than the above-mentioned space, for example, the plurality of horizontally adjacent building units are provided with openings to form the space. It will be. However, since the ceiling beam and the floor beam are exposed between these openings, it is difficult to give the impression of a single void space as a whole, and it may not be possible to fully enjoy the open space feeling. there were.

It is an object of the present invention to provide a unit-type building having a blow-through space with a feeling of openness and capable of withstanding a horizontal force such as an earthquake, and a method of constructing the unit-type building.

[0006]

In order to achieve the above object, the unit type building and its construction method of the present invention adopt the following constitution. When the present invention is described with reference to the drawings, the unit-type buildings 10 and 14 according to claim 1 are formed in a box shape by connecting upper and lower ends of columns 41 at four corners with ceiling beams 42 and floor beams 43. In a unit-type building including a lower building unit 12A in which a plurality of corners of a building unit 20 having a frame 40 are brought close to each other and an upper building unit 12B stacked on the lower building unit, At least two of the lower building units
In the two adjacent building units, the ceiling beams that are substantially parallel to each other are omitted, and the lower building unit for large space 2
1, the upper building unit above these large space lower building units has a floor beam adjacent to it which is substantially parallel to the omitted ceiling beam, and is defined as a large space upper building unit 22. At least one of the columns 47 located at both ends of the omitted ceiling beam and floor beam of the space lower building unit and the large space upper building unit is the reinforcement member 30.

Even if a horizontal force is applied due to the above, the pillars and the reinforcing members are integrated and bear the horizontal force, so that the rigidity of the unit-type building can be surely improved.

According to a third aspect of the present invention, in the unit type building according to the first or second aspect, the reinforcing material is provided over the entire length of the pillar to be reinforced. Characterize. According to this invention, since the reinforcing material is provided over the entire length of the column to be reinforced, it is possible to reinforce including the stigma and pedestal, which are particularly heavy when a horizontal load such as an earthquake is applied. Therefore, the rigidity of the unit type building can be further improved.

The unit type building according to claim 4 is the unit type building according to any one of claims 1 to 3, wherein the reinforcing material is between columns of the lower building unit and columns of the upper building unit. It is characterized by being continuously provided up to the interval. According to this invention, since the reinforcing material is continuously provided from between the pillars of the lower building unit to between the pillars of the upper building unit, the pillars of the upper and lower building units are integrally reinforced by the reinforcing material, The rigidity of the unit type building can be further improved.

A unit type building according to a fifth aspect is the unit type building according to any one of the first to fourth aspects, in which the reinforcing member is fixed to the upper surface or the lower surface of the pillar. It is characterized by having. According to the present invention, since the fixing member is provided on the reinforcing member, the fixing member fixes the position of the reinforcing member to the side surface of the pillar of the building unit, and the deviation can be suppressed, so that the unit type building is reliably reinforced. it can.

According to a sixth aspect of the present invention, there is provided a method of constructing a unitary building according to the first aspect of the present invention, which is used for constructing a unitary building. After manufacturing the lower building unit at the factory, install temporary beams on the ceiling beam and floor beam parts of the upper building unit for large space and the lower building unit for large space, and transport them to the site for large space. A plurality of lower building units are arranged with their corners aligned to form the lower building unit, and the large space building unit is stacked on these lower building units to form an upper building unit. After reinforcing at least one of the columns located at both ends of the omitted ceiling beam and floor beam of the large space lower building unit and the large space upper building unit with a reinforcing material, the temporary beam is removed. Characterized in that it.

According to the present invention, when the upper building unit for large space and the lower building unit for large space are transported to the site, temporary beams are provided on the omitted ceiling beams and floor beam portions, so that during transportation. Even if some vibration or shock is applied, the frames of the large space upper building unit and the large space lower building unit are not deformed, so that the construction accuracy of the unit type building can be secured.
