Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a joint structure of a housing unit that constitutes a housing of a unit construction method, and is particularly applicable to a skip floor type unit housing.

[Background technology]

2. Description of the Related Art Conventionally, a skip-floor type house is known in which the floors are offset by half a floor. In order to build this skip-floor type house with a general steel frame structure, as shown in FIG. 5, it was necessary to alternately install the beams 52 supporting the floor to the columns 51.

However, in such a structure, the diaphragm 53 had to be provided in the column 51 portion to which the beam 52 is connected in order to secure the strength. For this reason, it is necessary to connect a plurality of short steel columns through the diaphragm 53 to form the columns 51, which complicates the processing work and increases the welding work, resulting in poor workability. There was a problem of lowering.

[Problems to be Solved by the Invention] By the way, in recent years, it is possible to reduce the site work rate by shortening the construction period and reducing the cost by building a combination of housing units pre-produced in a factory. Unit housing has become widely used.

However, conventionally, there was no structure that joins the upper end or the lower end of the pillar of one housing unit and the middle of the pillar of the other housing unit in the longitudinal direction, so it is possible to build a skip-floor type house by the unit construction method. There wasn't.

Therefore, when building a skip floor type house, a general steel frame structure having the above-mentioned various problems must be used. Therefore, a skip floor type house by a unit construction method has been desired.

An object of the present invention is to connect the upper end portion or the lower end portion of one housing unit and the middle of the pillar of the other housing unit in the longitudinal direction, and thus it becomes possible to construct a skip-floor unit housing. It is to provide a joining structure of the unit.

[Means for solving the problem]

The joint structure of the housing unit of the present invention is such that a connecting plate having a projecting portion projecting from the side surface of the pillar is provided at the upper end portion or the lower end portion of the pillar of one housing unit, and the middle portion in the longitudinal direction of the pillar of the other housing unit. Is provided with a bracket having a joint portion, and the joint portion of the bracket and the projecting portion of the connection plate are connected so that the upper end portion or the lower end portion of the pillar of the one housing unit and the longitudinal direction of the pillar of the other housing unit. It is characterized in that the middle and the middle are joined.

[Action]

In the present invention, by connecting the connection plate provided on the upper end or the lower end of the pillar of one housing unit and the bracket provided on the pillar of the other housing unit, both housing units are The lower end is joined to the middle of the column in the longitudinal direction.

It is a structure that joins the housing unit 4 arranged on the raised high foundation 2B.

These housing units 3 and 4 are, as shown in FIG.
The ceiling beam 5 is provided only for the units 3 and 4 arranged on the uppermost floor, and the other units 3 and 4 are made of H-shaped steel joined between the pillar 6 of the square steel pipe and the diaphragm 7 at the bottom of the pillar 6. A so-called U-shaped unit composed of the floor beam 8 is used.

As shown in FIG. 3 and FIG. 4, a bracket 10 having a substantially L-shaped cross section is welded and fixed to a central portion in the height direction, which is in the longitudinal direction of the pillar 6 of the housing unit 3. A hole for joining is provided in the joining portion 11 which is erected from the pillar 6 of the bracket 10.
Two twelve are formed.

On the other hand, among the upper and lower housing units 4, the diaphragm 7 which is the lower end of the pillar of the upper housing unit 4A
And the stigma 6A, which is the upper end of the pillar 6 of the lower housing unit 4B
A flat plate-shaped connecting plate 20 is arranged between the and. The connection plate 20 is sandwiched between the housing units 4A and 4B and fixed by pressure. That is, the housing units 4A and 4B are
It is aligned by a guide pin 23 provided upright on the stigma 6A of B, and is joined by a high-strength bolt 25 screwed to a nut 25 in the diaphragm 7. Therefore, the connection plate 20 is sandwiched and fixed by the units 4A and 4B as the high-strength bolt 25 is tightened.

The connecting plate 20 is provided with a projecting portion 21 projecting from the side surface of the pillar 6, and the projecting portion 21 has a hole 12 of the bracket 10.
Corresponding to the above, two joining holes 22 are formed.

The diaphragm 7 that is the lower end of the pillar 6 of the housing unit 4A, that is, the connection plate 20 that is fixed to the pillar head 6A that is the upper end of the pillar 6 of the unit 4B, and the bracket 10 that is fixed to the pillar 6 of the housing unit 3 , Are connected through the joint plate 30.

The joining plate 30 is formed with two elongated holes 31 and 32 that are orthogonal to each other, and a bolt 33 and a nut that are screwed through the elongated holes 31 and the holes 12 of the bracket 10. 34 with slots 32 and holes 22 in connection plate 20
With the bolt 35 and nut 36 screwed through
The housing unit 3 and the housing units 4A and 4B are mounted so that their positions can be adjusted in the horizontal direction.

In order to join the two, the bracket 10 is attached midway in the longitudinal direction of the pillar 6 of the housing unit 3 and
The connecting plate 20 is fixed between the diaphragm 7 of 6A and the unit 4A. Next, the bracket 10 and the connecting plate 20 are connected via the joining plate 30.

Here, the housing unit 3 and the housing unit 4 are connected to the pillar 6 via the bracket 10, the connecting plate 20, and the joint plate 30.
The middle part in the longitudinal direction and the diaphragm 7 are joined together, that is, they are joined in a state where the floors are displaced, so that the skip-floor type unit house 1 is built.

According to this embodiment having such a configuration, the housing unit 3
The middle part of the pillar 6 in the longitudinal direction and the diaphragm 7 part of the housing unit 4 can be joined together, that is, the housing units 3 and 4 can be joined horizontally with their floors displaced in the height direction. You can build a house 1.

At this time, the bracket 10 is fixed to the pillar 6 by welding,
Since the connection plate 20 is crimped and fixed by the units 4A and 4B,
It is not necessary to process a diaphragm or the like in the middle of the pillars 6 that form the units 3 and 4, and members such as the pillars 6 can be shared with other housing units, and the cost can be reduced.

Also, since the bracket 10 has a short protruding portion from the pillar 6, it can be welded and fixed in advance at the factory. In this case, it is only necessary to tighten the bolts 25, 33 and 35 at the construction site. It is possible to join the units 3 and 4. Therefore, the site work ratio is reduced, the workability is improved, the construction period can be shortened, and the work cost can be reduced.

Further, since the bracket 10 and the connecting plate 20 are joined via the joining plate 30, even if the bracket 10
Even if the positions of 10 and the connection plate 20 in the height direction are deviated, the housing units 3 and 4 can be reliably joined by appropriately setting the shape of the joining plate 30 by providing a step or the like.

In addition, the joining plate 30 has elongated holes 31, 32 orthogonal to each other.
Since the above is formed, it is possible to connect the bracket 10 and the connecting plate 20 so that the position can be adjusted in the horizontal direction. Therefore, even if the horizontal positions of the housing units 3 and 4 are deviated, they can be reliably joined.

It should be noted that the present invention is not limited to the configuration and the like of the above-described embodiment, but includes modifications within a scope that can achieve the object of the present invention.

For example, although the present invention is used to join the U-shaped housing units 3 and 4 in the above embodiment, it may be used to join the box-shaped housing units.

Further, in the above-described embodiment, the present invention is used to join the lower end portion of the pillar 6 of the housing unit 4A and the upper end portion of the pillar 6 of the housing unit 4B to the pillar 6 portion of the housing unit 3; It can also be used for joining the diaphragm 7 at the lower end of the pillar 6 of 4B and the diaphragm 7 at the upper end of the pillar 6 of the housing unit 4A to the middle of the pillar 6 of the housing unit 3 in the longitudinal direction. At this time, the connection plate 20 can be fixed between the foundation 2B and the unit 4B or by being bolted to the diaphragm 7 of the unit 4A.

Further, in the above embodiment, the bracket 10 and the connecting plate
