Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a building constructed by a unit construction method.

[0002]

BACKGROUND ART In a unit type building, a frame is formed including columns and beams, and a plurality of building units in which wall materials, floor materials, ceiling materials, etc. are attached to this frame are produced at a factory,
These building units are sent by truck to the construction site of the unit type building, and the building units are moved back and forth, left and right, at the construction site.
It is built by combining the top and bottom.

[0003]

When trucking a building unit from a factory to a construction site, the dimensions of the building unit must meet legal shipping restrictions. Therefore, conventionally, the height dimension of the building unit has been within a certain range. Therefore, in the past, it is not possible to provide a large-scale void space in one building unit or a plurality of horizontally adjacent building units, or to provide a living room in which the ceiling space is a storage space,
Therefore, there is a problem in that the degree of freedom in floor plan design is limited.

The object of the present invention is to satisfy the height limitation during truck transportation, and to obtain a building unit having a height higher than that at the construction site, so that the degree of freedom in floor plan design can be secured. It provides a method of building a unit building.

[0005]

A unit-type building construction method according to the present invention produces a plurality of building units each having a skeleton including columns and beams in a factory, and at least two buildings are constructed at a construction site. It is characterized in that the units are stacked one above the other and the skeletons of these building units are joined together to provide a building component that can be regarded as one building unit in terms of strength.

[0006] In the above, the joining of the frameworks is performed, for example, by bridging the joining members to these frameworks and fastening the framework and the joining member with fasteners such as bolts, and in other examples, It is carried out by connecting the frames to each other at a plurality of points with pins. In addition, the pillars of the vertically stacked building units are joined together by fasteners such as a plurality of bolts.

[0007]

In the present invention, at least 2 at the construction site.
Since individual building units are stacked vertically and the frameworks of these building units are joined together so that they can be regarded as one building unit in terms of strength, each building unit produced at the factory and transported by truck to the construction site is The height of the building can be within the legal transportation limit, and at the construction site, since the building units are stacked and have a large height, one building unit can be installed in a unit type building. It is possible to provide a room with a stairwell similar to the one formed, or a storage space behind the ceiling,
It is possible to secure the degree of freedom in the floor plan design of a unit type building.

[0008]

Further, a top block 30 is attached to the upper ends of the pillars 9 of the building unit 1, holes 31 are formed in the center and four corners of the top block 30, and cutouts 32 are provided at each side corner. ing. The guide pin 3 is inserted into the female screw hole 29 at the center of the base plate 28.
When the building unit 3 is loaded on the building unit 1 after screwing the upper part of 3, the guide pin 33 is inserted into the central hole 31 of the top block 30 for guiding, and the high tension is applied from the cutout 32. The bolt 34 is inserted into the hole 31, screwed into the female screw hole 29, and tightened.

In FIG. 7, the base plate 28 is attached to the pillar 13 of the building unit 3 in the same manner as described above, and the building unit 1
A top plate 35 is attached to the upper end of the pillar 9.
Holes 36 are formed in the center and four corners of the top plate 35, and before the building units 3 are stacked on the building unit 1, the guide pins 33 and the upper portions of the high tension bolts 37 are screwed into the female screw holes 29 of the base plate 28. After stacking, the high-tensile nut 39 is screwed from the notch 38 of the column 9 into the high-tensile bolt 37, the lower portion of which protrudes from the hole 36 of the top plate 35, and is tightened.

In the joint structures according to these embodiments, the frames 8 and 12 of the building units 1 and 3 are rigidly joined at the columns 9 and 13 by the high tension bolts 34 and 37 which are fasteners. Also in these examples pillars 9, 1
Since 3 has the same strength and rigidity as one continuous column, these building units 1 and 3 can be regarded as one building unit in terms of strength.

The joint structure described above is an example, and the present invention is not limited to this. For example, a rigid joint and a pin joint may be combined.

[0020]
