DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a joint structure between a wall panel and a floor panel, and a building unit using the same.

[0002]

2. Description of the Related Art As a building unit, there is a so-called wall winning building unit in which an end surface of a floor panel is joined to a side surface of a wall panel as disclosed in Japanese Patent Application Laid-Open No. 61-204443.

[0003]

However, in the building unit described in the above publication, the wall panel is provided with a large concave portion (hole) continuous to substantially the entire length in the lateral direction for fitting the end of the floor panel. I have. For this reason, in the above-mentioned building unit, the cross-sectional loss of the wall panel, that is, a decrease in strength is increased, and there is a possibility that sufficient structural strength cannot be secured.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described circumstances, and it is possible to reduce the cross-sectional loss of a wall panel, sufficiently secure structural strength, and improve the productivity of floor panels. It is an object of the present invention to provide a joint structure between a wall panel and a floor panel and a building unit.

The wall panel is configured to protrude from the end joist,
A plurality of the above vertical frames are hung and floor support materials are installed,
A plurality of fitting grooves are formed in the floor receiving member, and the protrusions in the floor joists of the floor panel are fitted in the fitting grooves in the floor receiving member of the wall panel, thereby forming the floor. The panel and the wall panel are joined.

According to a second aspect of the present invention, in the first aspect of the present invention, a tapered surface is formed on the projection of the floor panel.

[0007] The invention described in claim 3 is the first or second invention.
In the invention described above, the end joists of the floor panel are directly in contact with and joined to the floor receiving material of the wall panel.

According to a fourth aspect of the present invention, the wall panel and the floor panel are joined by the joint structure of the wall panel and the floor panel according to any one of the first to third aspects.

[0009]

The invention described in claim 1 has the following operation.
Since the joint between the floor panel and the wall panel is realized by fitting the protrusion of the floor joist of the floor panel into the fitting groove of the floor receiving material bridged over the vertical frame of the wall panel, On the inner wall,
A notch (insertion hole) having a sufficient cross-sectional area for inserting the protrusion of the floor panel may be provided. For this reason, the cross-sectional loss of the wall panel can be reduced, and the structural strength of the wall panel can be sufficiently ensured.

Further, the end joist of the floor panel is formed in a comb shape having a plurality of slits, and the projection of the floor joist engages with the slit of the end joist to form the floor panel. In addition, the connection between the end joist and the floor joist becomes easy, and the productivity of the floor panel can be improved.

Further, since the cross-sectional area of the fitting groove of the floor receiving material of the wall panel and the projection of the floor joist of the floor panel can be set large, the horizontal shear force between the floor panel and the wall panel is reliably supported. It is possible to improve the strength of the joint between the floor panel and the wall panel, and hence the reliability of the strength of the building unit.

Further, since the floor receiving material is hung over a plurality of vertical frames of the wall panel, the end of the floor panel is connected to a floor receiving material other than the vertical frame of the wall panel, for example, in the vicinity of the vertical frame. Can be fixed using a nail or the like. For this reason, the joint strength between the floor panel and the wall panel can be further increased.

The second aspect of the invention has the following operation. Since the projection of the floor panel is formed with a tapered surface, the projection of the floor panel and the floor receiving material of the wall panel can be joined in close contact with each other, and problems such as floor noise can be reliably prevented.

The third aspect of the invention has the following operation. Since the end joists of the floor panel are directly in contact with the floor receiving material of the wall panel and are joined to the wall panel, it is possible to lengthen the driving length of the joint fitting such as a nail, and to increase the joint strength between the wall panel and the floor panel. Can be higher.

According to the fourth aspect of the invention, it is possible to realize a building unit capable of sufficiently securing the structural strength of the wall panel and improving the productivity of the floor panel.

Open at 23. Accordingly, the connection between the floor joists 13 and the end joists 14 is performed by lowering the end joists 14 from above the protrusions 30 of the plurality of floor joists 13 and engaging the protrusions 30 with the slit portions 22 of the end joists 14. This is done by: As described above, in the floor panel 12 configured by connecting the floor joists 13 and the end joists 14, the protrusions 30 of the floor panel 12 connected to the end joists 14 project from the end joists 14.

On the other hand, a plurality of vertical frames 1
7, a notch 31 is formed, and a floor receiving member 32 is fitted into the notch 31 of each of the vertical frames 17.
2 is stretched over a plurality of vertical frames 17. The fitting groove 3 is provided at a position corresponding to each vertical frame 17 of the floor receiving member 32.
3 are formed. Also, as shown in FIGS.
An insertion hole 34 is formed in the lower plywood 21 of the wall panel 11 at a position corresponding to each fitting groove 33. This plywood under the wall 21
Functions as a reinforcing plate for compensating for a cross-sectional defect of the vertical frame 17 due to the formation of the notch 31 in the vertical frame 17.

After assembling the wall panel 11 and the floor panel 12, the projections 30 of each floor joist 13 of the floor panel 12 are inserted into the insertion holes 3 of the plywood 21 under the wall in the wall panel 11.
4 and the protrusion 30 is fitted into the fitting groove 3 of the floor receiving material 32.
3 and the wall panel 11 and the floor panel 12 are joined to form the building unit 35.

Here, before the wall panel 11 and the floor panel 12 are joined, the protrusion 30 of the floor panel 12 or the wall panel 11
An adhesive may be applied to at least one of the fitting grooves 33, and the bonding between the floor panel 12 and the wall panel 11 may be strengthened by solidifying the adhesive.
