2. Description of the Related Art As a building unit constituting a unit building, as shown in FIG. 9, a wall panel 3 composed of a wall frame and a wall material is provided on a side edge of a floor panel 2 composed of a floor frame and a floor surface material. 2. Description of the Related Art A building unit 1 configured to stand upright is known. When assembling the building unit 1, the floor panel 2 and the wall panel 3 are nailed from the lower frame of the wall frame to the joist of the floor frame, or by using an L-shaped joint fitting (also referred to as an L-shaped fitting) 30. The joining method is adopted (Japanese Patent Publication No. 59-
No. 50835).

When assembling a unit building using the building unit 1, the upper end of the building unit 1 is lifted by a crane using the hanging tool 31, and the building unit 1 is placed on a foundation or a lower-floor building unit. Installing an upper-floor building unit on top is performed.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a building unit constituting a unit building, and this building unit 1 is assembled at a factory. The building unit 1 includes a floor panel 2 and a wall panel 3 erected on a side edge of the floor panel. The floor panel 2 is, as shown in FIG.
And a floor panel 5 such as a plywood or a particle board stretched on the upper surface of the floor frame 4.

The floor frame 4 is assembled by nailing side joists 7 between opposite ends of the end joists 6 and nailing a plurality of joists 8 between the end joists 6. A base 9 (9a, 9b) is attached to the lower peripheral portion of the floor frame 4 as a joining portion for joining to a foundation or joining a lower-floor building unit and an upper-floor building unit.

As shown in FIG. 3, the wall panel 3 includes a wall frame 10, an inner wall material (not shown) such as a gypsum board stretched on an inner surface 10 a of the wall frame 10, and a wall frame 10. An outer wall material (not shown) such as a hard wood cement board stretched on the outer surface 10b. Basically, the above-mentioned wall frame is assembled by nailing a plurality of vertical frames 13 between the upper frame 11 and the lower frame 12 facing each other with a lip.

The wall frame 4 is provided with a projecting portion 14 projecting downward so that the wall panel 3 is erected and joined to the side edge of the floor panel 2. It is positioned on the inner surface and joined with nails 15. In this case, a pair of vertical frames 13a provided on both sides in the width direction of the wall frame 10,
A paddle 16 is sandwiched between the lower frames 13b with its lower end protruding from the lower frame 12, and fixed by nailing. That is, the protruding portion 14 is formed by a lower end portion protruding from the lower frame 12 of the shank 16.

The projecting portion 14 is inserted into an inner corner (corner portion) of the floor frame 4 so as to be in contact with the inner surface of the floor frame 4. Therefore, the floor member 5 is provided with a notch 17 into which the protrusion 14 is inserted. The above protrusion 1
Preferably, the length of the protrusion 4 is such that the lower end of the protrusion 14 just abuts on the upper surface of the base 9 when inserted into the inner corner of the floor frame 4.

In the illustrated example, the lower frame 12 of the wall frame 10 is shown.
The lower surface is designed to contact the upper surface of the floor panel 5 in the floor frame 4, and the lower end of the outermost vertical frame 10a is designed to contact the upper surface of the end joist 6 in the floor frame 4 (see FIG. 2). As shown in FIGS. 2 to 5, a plurality of nails 15 are appropriately driven from the outer surface of the lateral joist 7 to join the projecting portion 14 to the lateral joist 7.

When assembling the building unit 1 having the above structure, first, the projections 14 on both sides of the wall frame 10 are inserted into the inner corners of the floor frame 4 from above, and then,
What is necessary is just to drive and fix the nail 15 in the said protrusion part 14 from the outer side of the floor framework 4. When the floor frame 4 and the wall frame 10 are joined in this way, an inner wall material is stretched on the inner surface of the wall frame 10 and an outer wall material is stretched on the outer surface of the wall frame 10 so as to cover the outer surface of the floor frame 4. do it.

The thus constructed building unit 1
According to the method described above, the projection 14 protruding downward is provided on the wall frame 10 of the wall panel 3, and the projection 14 is positioned on the inner surface of the floor frame 4 of the floor panel 2 and joined with the nail 15, so that the L-shaped bracket It is possible to securely and easily join the floor panel 2 and the wall panel 3 without using the slab, thereby improving the workability and preventing the floor panel 2 and the wall panel 3 from being disassembled when the unit is lifted.

Further, the projecting portion 14 is provided on the wall frame 10.
Since the timber 16 sandwiched between the pair of vertical frames 13a and 13b is extended so as to protrude downward from the lower frame 12 of the wall frame set 10, the protruding portion 14 is integrally formed with the wall frame set 10. And a strong configuration.

FIGS. 6 and 7 show another embodiment of the present invention, in which the same parts as those in the above embodiment are denoted by the same reference numerals. Building unit 1 of the present embodiment
In the above, the projection 14 provided on the wall frame 10 of the wall panel 3 so as to protrude downward is attached to the floor frame 4 of the floor panel 2.
And is joined by bolts 18. As shown in FIG. 8, the bolt 18 in the illustrated example has a plate-shaped head 18a at the base end, and a small hole 20 for fixing with a nail 19 as a detent on the head 18a. Is provided. The bolt 18 is connected to the protrusion 14 and the side joist 7.
Is inserted from the outside of the lateral joist 7 into a bolt hole 21 provided in the
Is to be tightened. According to the building unit of the present embodiment, the projecting portion 14 of the wall panel 3 is located on the inner surface of the floor frame 4 of the floor panel 2 and is joined with the bolt 16 and the nut 21. Therefore, an L-shaped fitting is used. Thus, the floor panel 2 and the wall panel 3 can be securely and easily joined without any problems, thereby improving workability and preventing the floor panel 2 and the wall panel 3 from being disassembled when the unit is lifted.
