DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a panel joining method according to the present invention will be described below with reference to FIGS. In the embodiment shown in FIGS. 1 and 2, the abutting ends of both floor panels P1 and P2 whose end faces are butted against each other are placed on the upper end face 10 of the wall panel P3 built in the building. This shows a suitable example as a panel joining method for joining them together.

In the panel joining method according to this embodiment, before the floor panels P1 and P2 are placed on the wall panel P3, first, the upper end surface 10 of the wall panel P3 and the joining end surfaces 11 and 12 of the floor panels P1 and P2 are first joined. An adhesive S for wood is applied to at least one joint end surface. As the adhesive S, for example, a urethane-based adhesive (
) And the like are used.

On the other hand, at least one joint end face of the floor panels P1 and P2 is provided with a guide groove 13 extending along the joint end face in the thickness direction of the floor panels. The guide groove 13 is used when a long screw 14 described later is screwed in. In the embodiment, the guide groove 13 is provided in the joint end surface 11 of the floor panel P1 in the form of a notch groove formed by forming a saw. . The guide groove 13 formed in the notch groove shape is provided so as to extend along the joint end surface 11 of the floor panel P1 in the entire thickness direction of the floor panel P1. The guide groove 13 is formed to have a groove width and a groove depth which are equal to or smaller than the diameter of the body portion of the long screw 14 shown in FIG. As the long screw 14, about 1/4 from the tip is the screw thread 14A.
It is shown with a head 14B formed on the. The guide groove 13 can be provided at the site if necessary, but normally, it is desirable to provide it at the same time when the floor panel is manufactured in a factory in consideration of workability.

After the floor panels P1 and P2 are placed on the wall panel P3, the joining end surfaces 11 and 12 of the floor panels P1 and P2 are brought into close contact with each other by using a panel pulling jig or the like, if necessary, and the screw is attached in this state. As shown in FIG. 2, the nail 15 is driven diagonally downward from the upper surfaces of the panels to the mating core members 16 and 17 to join the floor panels P1 and P2.

Then, a long screw 14 designed to be longer than the thickness of the floor panels P1 and P2 is screwed into the guide groove 13,
Further, the tip of the long screw 14 is attached to the core material 1 of the wall panel P3.
The floor panels P1 and P2 are fixed to the wall panel P3 by screwing into the wall panel 8.

According to such a joining method, the floor panel P
It is possible to perform all the joining work between 1, P2 and the floor panel P1, P2 and the wall panel P3 from above the floor panel, and therefore, as in the conventional case, especially diagonally upward from the wall panel to the floor panel. Since it is not necessary to perform the joining work such as performing nailing toward the work which is poor in workability and works at a high place, the joining work can be performed in a very good and safe working environment.

Further, in the case of such a joining method, the floor panels P1 and P2 for joining the joining end faces 11 and 12 by abutting each other and joining the floor panels P1 and P2.
P2 and the wall panel P3 are firmly adhered to each other by the adhesive S. At this time, the floor panels P1 and P2 are connected to the wall panel P3.
Since the long screws 14 are screwed in and fixed to the floor panels P1 and P2, the floor panels P1 and P2 are strongly pressed against the wall panels P3, and at the same time, the floor panels P1 and P2 and the wall panels P3 are simultaneously fixed.
It is accurately positioned so that the joining position with and does not shift.
At this time, the adhesive S is also clamped, so that the adhesive strength is correspondingly improved. Further, the long screw 14 is attached to the guide groove 13
Since the guide groove 13 of the long screw 14 is provided along the joint end surface 11 of the floor panel P1 while being guided and positioned, the guide groove 13 of the long screw 14 is provided with one long screw 14. The floor panels P1 and P2 are simultaneously fixed to the wall panel P3.

In the embodiment, the guide groove 13 is formed as a notched groove having a flat rectangular shape by sawing, mainly in consideration of its workability. However, for example, the guide groove 13 is formed in a circular shape such as a normal front hole. Of course, it may be formed.

FIG. 4 shows a second embodiment of the present invention, in which the upper end surface 20 of the wall panel P4 built around the building exterior.
This is applied to a panel joining method in which an end portion on one end side of the floor panel P5 is placed on the floor panel P5, and a barrel gap 22 is arranged on the end face on the one end side to join them together.

In this embodiment, there is a difference between the floor panels to be joined to each other in the body difference, which is basically the same as the previous embodiments. A step of providing a guide groove 23 extending in the thickness direction of the floor panel P5 along the joint end face of the P5 and the body difference 22, and the upper end surface 20 of the wall panel P4 and the floor panel P4 and the body difference 22
A step of applying an adhesive S to each of the joint end surfaces of
A step of joining the floor panel P5 and the body difference 22 by nailing, and a long screw 24 longer than the thickness of the floor panel P5 along the guide groove 23 from above the floor panel P5 to the wall panel P4. The floor panel P5 and the body difference 22 are fixed to the wall panel P4 by screwing.

Here, in order to fix the floor panel P5 and the body difference 22 by nailing, as shown in FIG. 4, screw nails 26 are provided from the outer surface of the body difference 22 toward the core material 25 of the floor panel P5. It can be fixed by striking straight.

The operational effects of this embodiment are also as follows.
Although it is almost the same as the previous embodiment, in this example, since the wall panel P4 is a wall panel to be built on the outer circumference of the building, an inorganic board that is difficult to nail is often used for the face material 26. This is especially effective in the case.

[0023]

As described above, according to the panel joining method of the present invention, various excellent effects as described below can be obtained.

According to the panel joining method of claim 1,
The floor panels, whose end faces are butted against each other, and the floor panels and the wall panels are firmly bonded together with an adhesive, and both floor panels are tightened by screwing long screws against the wall panels. Since it is fixed, the floor panel can be strongly pressed against the wall panel, and at the same time, the floor panel and the wall panel can be accurately positioned so as not to shift the joint position. At this time, the adhesive is also clamped, so that the adhesive strength can be improved accordingly. further,
The long screws are guided and positioned in the guide grooves and are accurately screwed in.The guide grooves of the long screws are provided along the joint end surface of the floor panel, so both can be performed with a single long screw. Floor panels can be fixed to wall panels at the same time.

In such a panel joining method, even if there is unevenness in the application of the adhesive, it is possible to secure sufficient joining strength with the long screws, and to join the floor panels together. All the work and the joining work between the floor panel and the wall panel can be performed from above the floor panel. Therefore, the workability such as nailing diagonally upward from the wall panel to the floor panel is required as in the conventional work. Since it is not necessary to perform the joining work which is a bad work at a high place, the joining work can be carried out in an extremely good and safe working environment.

In the panel joining method according to the second aspect, all the joining work between the floor panel and the body difference and the joining work between the floor panel and the wall panel can be performed from above the floor panel. However, since it is not necessary to perform the joining work such as the nail work that is diagonally upward from the wall panel to the floor panel, which is poor in workability and which requires work at a high place as in the past, the joining work is extremely difficult. It can be implemented in a good and safe working environment. Also,
In the case of this method, since the wall panel is a wall panel that is built around the exterior of the building, it is particularly effective when the surface material is frequently made of an inorganic board that is difficult to nail.
