Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of a unit building and a building unit.

[0002]

2. Description of the Related Art As a conventional joint structure of a unit building, for example, one shown in FIG. 8 is known. In such a structure, the substantially rectangular parallelepiped-shaped structure 1a constituting the first-floor building unit 1 is provided with pillar members 2 arranged at four corners.
The pillar member 2 is mainly configured by an upper beam 3 extending over the upper edge portion and a lower beam 4 extending over the lower edge portion.

On the lower surface side of the structure 1a, a flat floor unit 7 is fixed to the pillar 2 and the lower beams 4 and 4 by connecting them with L-shaped plates 5 and 5 and nails 6 ... There is. Further, between the floor unit 7 and the L-shaped plate 5, head joists 8 as lateral members fixed to the joists 7a of the floor unit 7 are inserted along the lower edge of the floor unit 7. Has been done.

The second-floor building unit 11 is also constructed in substantially the same manner as the first-floor building unit 1.

In this state, the bolts 12 projecting upward from the foundation 9 are inserted into the bolt holes 8a formed in the head joint 8 to mount the first floor building unit 1 thereon. The foundation 9 and the head joint 8 are fastened with bolts 12 and nuts 13.

Next, the second-floor building unit 11 is placed on the first-floor building unit 1, and the upper frame 3 of the first-floor building unit 1 and the head joint 8 of the second-floor building unit 11 are fixed with bolts 12 and nuts. Fasten at 13.

Further, when the building units 1 and 11 are transported, eyebolt fixing fittings 2a arranged in the pillar members 2 ...
An eyebolt 10 is screwed on the eyebolt 10, and a crane rope (not shown) is passed through the eyebolt 10 to lift it.

As another type of this type, there is known one such as described in JP-A-60-105738.

[0009]

However, in such a conventional one, the head joint 8 which is a cross member is
The first-floor building unit 1 is fixed to the foundation 9 and the second-floor building unit 11 is fixed to the upper beam 3 by fastening bolts 12 and nuts 13, respectively.

A floor unit 7 in which the head tie 8 is arranged
The connection between the column member 2 and the pillar member 2 is only fixed by the nails 6 ... Performed via the L-shaped plate 5, and a low strength portion is used for connecting the structures 1a, 1a of the first and second floor building units 1, 11. I will intervene. Therefore, it was difficult to obtain high strength in the entire unit building.

Moreover, this L-shaped plate 5 ...
And the first-floor building unit 1 and the first-floor building unit 1 and the second-floor building unit 11 are interposed, and there is a possibility that a dimensional error may occur during installation.

Further, since the eyebolt fixing metal fittings 2a must be separately provided in the pillar member 2, there is a problem that the number of parts of the eyebolt fixing metal fitting 2a increases.

Therefore, the present invention aims to provide a joint structure for a unit building, which can improve the strength of the unit building, reduce the possibility of dimensional error during installation, and increase the number of parts. I am trying.

The connection bracket 22 maintains the substantially rectangular shape while fixing the floor unit 19 to the lower surface side even during transportation. Therefore, unlike the conventional case, it is not necessary to dispose the L-shaped plate, and the risk of dimensional error during installation is reduced.

When the second-floor building unit 16 is vertically stacked on the first-floor building unit 15 by means of bolts 12 and nuts 13 as fasteners, the upper bracket 20 of the first-floor building unit 15 and the second-floor building unit 15 are stacked. The 16 connecting brackets 22 are fixed as shown in FIG.

Further, as shown in FIG. 1, a roof unit 17 is placed on the second-floor building unit 16, and the upper bracket 20 of the second-floor building unit 16 and the roof unit 17 are placed.
The lower bracket 21 and the lower bracket 21 are connected and fixed by bolts 12 and nuts 13.

Therefore, the W stud pillars 18 and 1 on the upper and lower floors
8 is directly connected and fixed from the foundation 9 to the roof unit 17 by the upper bracket 20, the lower bracket 21, and the connecting bracket 22, so that a low-strength portion is provided in the conventional path for transmitting force. The strength can be improved as compared with the structure having.

Further, since the hanging eyebolts 10 are removably arranged on the upper brackets 20 ..., it is necessary to prepare a metal fitting for separately arranging the hanging eyebolts 10 as in the conventional case. There is no. For this reason, sufficient strength can be secured during transportation and installation without increasing the number of parts.

Moreover, in this embodiment, each bracket 2
Since 0, 21, 22, ... Are fixed from the inside, the appearance quality is also good.

4 to 5 show a joint structure of a unit building according to the second embodiment of the present invention. The same or equivalent parts as those of the unit building connection structure of the first embodiment will be described with the same reference numerals.

In this second embodiment, the connecting bracket 32 as a part of the lower bracket is arranged at the corner where the beams 19a, 19a of the floor unit 19 are made orthogonal to each other and abutted against each other, and the nail 6 … By both beams 19a, 19a
It is fixed to. The other structure and operation, such as the connection bracket 32 being connected to the lower bracket 21 by the bolts 12 and the nuts 13, are substantially the same as those in the first embodiment, and therefore the description thereof will be omitted.

Naturally, it can be a pillar.

[0055]

As has been described above, according to the first aspect of the present invention having such a structure, the structure of the building unit can be substantially removed by the upper and lower brackets disposed inside, even during transportation. The rectangular shape is maintained. For this reason,
There is no need to dispose an L-shaped plate as in the conventional case, and the risk of dimensional error during installation is reduced.

Further, since the pillar members on the upper and lower floors are directly connected and fixed by the lower and upper brackets, the strength is improved as compared with the structure having a low strength portion in the conventional path for transmitting the force. It can be done.

According to the second aspect of the present invention, the structure of the building unit is maintained in a substantially rectangular shape even during transportation by the upper and lower brackets disposed inside. Therefore, unlike the conventional case, it is not necessary to dispose the L-shaped plate, and the possibility of causing a dimensional error even in the horizontal direction during installation is reduced.

Further, since the column members of the adjacent building units are directly connected and fixed by the lower or upper brackets, the column members of the conventional structure have a low strength portion in the path through which the force is transmitted. The strength can be improved.

According to the third aspect of the invention, since the hanging eyebolt is detachably arranged on the upper bracket, the hanging eyebolt is separately arranged as in the conventional case. There is no need to prepare metal fittings.

Therefore, there is a practically useful effect that a sufficient strength can be secured during transportation and installation without increasing the number of parts, and a joint structure of a unit building with a small dimensional error can be provided. Demonstrate.
