Abstract

PROBLEM TO BE SOLVED: To provide a unit connecting method which can reduce finish work in a field of construction after upper and lower building units are connected and place no limitation on the range of application floor in connecting between an upper floor building unit and a lower building unit. SOLUTION: A guide pin 6 is fixed to an upper plate 4 of a support of a lower floor building unit. A locking pin 8 of a middle plate 9 is inserted in a locking pin insert hole provided in the upper plate 4. After that, the upper floor building unit is stacked on the lower floor building unit. At this time, when a guide bottom part 5 of a lower plate 3 and the head part of the guide pin 6 abut on each other, the middle plate 9 is freely slid. After the upper floor building unit and the lower floor building unit are stacked, the middle plate 9 is slid to connect the upper floor building unit and the lower floor building unit to each other.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit, and more particularly to a building unit capable of easily joining an upper-floor building unit and a lower-floor building unit.

[0002]

2. Description of the Related Art In prefabricated houses, unit houses formed by joining a plurality of box-shaped units are increasing as means for increasing the rate of factory production. Conventionally, however, the upper-floor building unit and the lower-floor building unit are joined by fastening the lower flange 17 of the upper-floor building unit and the upper flange 16 of the lower-floor building unit with bolts and nuts, as shown in FIG. ing. Therefore, there was a defect that this part had to be closed after the on-site joining work. Therefore, the advent of a joining method that reduces the on-site work after unit joining on the upper and lower floors has been eagerly desired.

In the second conventional example, as shown in FIG. 8, a bolt 19 is attached to a lower-floor building unit using a special tool 20 that is close to 3 meters from above a support pipe 21 of the upper-floor building unit. I am working to tighten it to 18. However, in this method, since the column of the building unit is long, the dedicated tool 20 is inevitably long, and the work is not easy. Moreover, in such a method, a hole is required above the support pipe 21 of the building unit so that at least the special tool 20 can be inserted. The constituent elements of the support pipe of the upper-floor building unit and the lower-floor building unit are different. Range was also limited.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and reduces the work required at the construction site after the upper and lower building units have been joined together, and at the same time reduces the number of upper floor building units. It is an object of the present invention to provide a unit combining method in which the range of applicable floors is not limited in combining a building unit with a lower building unit.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a unit joining structure for a unit housing in which a plurality of box-shaped units are joined, wherein an upper floor building unit and a lower floor building unit are connected to each other. A lower plate of a floor building unit and an intermediate plate provided with a pin for locking an upper plate of a lower floor building unit are engaged, and the upper floor building unit and the lower floor building unit are connected by sliding the intermediate plate. It is.

[0006]

Hereinafter, the present invention will be described in detail based on illustrated embodiments. FIG. 1 is a sectional view of an example showing a fastening state of a building unit to which the present invention is applied. As shown in FIG. 1, a nut 7 is provided on the upper plate 4 of the column 2 of the lower-floor building unit.
Is welded. Therefore, first, the guide pins 6 are fixed to the upper plate 4. Next, as shown in FIG. 3, the locking pins 8 of the intermediate plate 9 are inserted into the locking pin insertion holes 10 provided in the upper plate 4. The upper-floor building unit is stacked on the lower-floor building unit with the intermediate plate 9 and the upper plate 4 in a positional relationship as shown in FIG. Then, since the lower plate 3 of the upper-floor building unit also has the same locking pin insertion hole 10 as the upper plate 4 of the column 2 of the lower-floor building unit, the locking pin 8 and the lower plate 3 do not interfere. Thus, the upper-floor building unit and the lower-floor building unit are stacked.

At this time, a truncated cone-shaped recess is formed in the lower plate 3 of the upper-floor building unit 1, and the recess is formed in a shape that can be fitted with the guide pin 6. Positioning work is easy. The length of the guide pin 6 is such that the intermediate plate 9 can slide freely in the gap between the upper plate 4 and the lower plate 3 when the guide bottom 5 of the lower plate 3 and the head of the guide pin 6 abut. Stipulated in Therefore, even after the upper-floor building unit is stacked on the lower-floor building unit, the weight of the upper-floor building unit is received by the guide bottom of the lower plate 3 and the head of the guide pin 6, so that the intermediate plate 9 can be easily slid. Is available.

After the upper building units and the lower building units are stacked, the intermediate plate 9 is slid in the direction B as shown in FIG. Then, the locking pin 8 moves along the locking pin sliding groove 11 provided on the upper plate 4 and the lower plate 3. However, since the projection 12 is provided at the edge of the locking pin sliding groove 11, the upper plate 4 and the lower plate 3 are fastened by the projection 12 pressing the head of the locking pin 8. The state at that time is shown in FIG.

FIG. 5 is a sectional view of two examples showing a fastening state of a building unit to which the present invention is applied. In the present embodiment, the upper plate 1 corresponds to the guide pin 6 shown as an example.
3 in which a convex portion is formed.

FIG. 6 is a top view of three examples showing a fastening state of a building unit to which the present invention is applied. In this example, the upper plate building unit and the lower floor building unit are fastened by sliding the intermediate plate 15 linearly in the F direction.

[0010]

As described above, when the method of fastening building units according to the present invention is used, the range of applicable floors is not limited in coupling the upper floor building unit and the lower floor building unit.
In addition to reducing the closing work at the construction site,
A building unit combining method that can improve the factory production rate of building units can be easily obtained.
