In this specification, the term "inside" refers to the side that is viewed from the outside, such as the indoor side, and the term "outside" refers to the opposite side.

BACKGROUND TECHNOLOGY Conventionally, when joining and joining two plates of this type, as shown in FIGS. The outer protruding edge 1a and the inner protruding edge 2a are formed in opposite directions, and the outer protruding edge 1 of one plate 1 is
After fixing a to the trunk edge 7 with nails 13, etc., apply adhesive 10 to the overlapping surfaces of the protruding edge 1a, and overlap the inner protruding edge 2a of the other plate material 2 on the protruding edge 1a. A batten 11 is arranged so as to straddle the joint ends of these two planks 1 and 2, and the corresponding tree 11 is temporarily fixed by nails 12, 12 to the rim 7, and then glued. A method has been adopted in which the batten 11 and nails 12, 12 are removed after the agent has hardened to connect and fix them.

Problems to be Solved by the Invention However, when the above-mentioned connecting means is adopted, nails must be driven into the boards to be joined in order to perform temporary fixing, and the temporary fixing work is not only troublesome, but also Nail holes remain after temporary fixing nails are removed, and to make them less noticeable, the keyholes must be filled with putty or crayon in the same color as the board, resulting in poor appearance and workability on site. It was hot.

The present invention has been made to solve the above-mentioned problems, and provides a board joining structure that improves workability on site and provides a good appearance without keyholes or the like appearing in the finished state. The purpose is to

Means for Solving the Problems Therefore, in the present invention, the plate materials 1 and 2 to be joined to each other have an outer protruding edge 1a and an inner protruding edge formed at the joining edges of the plates, the inner and outer sides of which are opposite to each other. 2a are overlapped and abutted, and both of these plate materials 1 and 2 are connected by a connecting member 4, the connecting member 4 having an inner fitting piece 4a and an outer fitting piece 4b. It has a base end portion 5 that is approximately U-shaped in side view, extends from the base end side of the outer side contact piece 4b of the base end portion 5 to the opposite side thereof, and is curved in an inwardly bulging shape. It has a clamping tongue piece 4c, and the inner fitting piece 4a is fitted into the notch 2b formed in the abutting step surface 2d on the base end side of the inner protruding edge 2a of one of the plate materials 2, and The contact piece 4b is along the outer surface of the plate material 2, while the clamping tongue piece 4c and the inner protruding edge 2a
The gist of this invention is a structure for joining plates such as ceiling plates and wall plates, in which the outer protruding edge 1a of the other plate 1 is held in a pinched state between the two plates.

Function The connecting member 4 has an inner fitting piece 4a at its base end 5.
is fitted into the notch 2b formed in the abutting step surface 2d on the proximal side of the inner protruding edge 2a, and the outer creeping piece 4b is brought into contact with the outer surface of the plate material 2, so that one side It is fixed to the plate material 2. By inserting the outer protruding edge 1a of the other plate material 1 between the clamping tongue 4c and the inner protruding edge 2a of the connecting member 4, the protruding edge 1a is caused to protrude inwardly from the clamping tongue 4c. The clamping tongue piece 4 is inserted between the edge 2a and the edge 2a.
The elastic force of c holds the plates 1 and 2 in a sandwiched state, thereby connecting the plates 1 and 2.

Embodiments Hereinafter, the present invention will be explained based on illustrated embodiments.

FIGS. 1 to 4 show the application of the present invention to the joining of plate materials constituting a wall panel.

The plate materials 1 and 2 to be joined to each other have an outer protruding edge 1a and an inner protruding edge 2a, which are opposite to each other, formed on the joining edges on both sides, and the inner protruding edge 2a is A notch 2b is formed continuously on the outer surface. This notch 2b
Although it is advantageous in manufacturing to form it at the above position, it may be formed at any position on the abutting step surface 2d on the proximal end side of the inner protruding edge 2a.

The adjacent plate materials 1 and 2 are connected and fixed to each other with the overlapping surfaces 1e and 2e of the protruding edges 1a and 2a overlapping each other. In this embodiment, the length of the inner protruding edge 2a is set shorter than that of the outer protruding edge 1a, so that a joint 3 is formed at the joint portion in the overlapping state.

The two plates 1 and 2 are connected by a dedicated connecting member 4 in the overlapping state.

As shown in FIG. 3, this connecting member 4 is a narrow inner fitting piece formed by bending one side edge of a single rectangular metal plate in the axial direction into a substantially L-shaped shape when viewed from the side. 4a is formed, and by cutting the lengthwise middle part of the other side side along the width direction at a predetermined interval and folding back the middle part, an outer side parallel to the fitting piece 4a is formed. A piece 4b is formed, and the remaining part on the other side side is the outer side contact piece 4.
The clamping tongues 4c, 4c are formed in an arc shape and bulge toward the inner fitting piece 4a from the surface b, and the outer fitting piece 4b and the inner fitting piece 4a are connected to each other.
The base end portion 5 is generally U-shaped in side view.

As shown in FIG. While fitting into the notch 2b, the outer side contact piece 4b is brought into contact with the outer surface of the plate material 2. As a result, the connecting member 4 is fixed to one of the plate members 2. In order to maintain this fixed state firmly,
It goes without saying that it is necessary to match the distance between the creeping piece 4b and the fitting piece 4a to the distance between the notch 2b of the plate material 2 and the outer surface.

On the other hand, the outer protruding edge 1a of the other plate 1 is fixed in advance to the trunk edge 7 with screws 6, as shown in FIG. 4b. After that, as shown in FIGS. 4c and 4d, the one plate 2 to which the connecting member 4 to be connected is attached is connected to the inner protruding edge 2a and the clamping tongue 4c of the connecting member 4. The outer protruding edge portion 1a is fitted between the two parts in a manner such that the outer protruding edge part 1a is clamped between the two parts. In this connected state, both the inner and outer protruding edges 1a, 2a are firmly pressed and fixed to each other due to the elastic force of the arched, curved clamping tongues 4c. Therefore, the connecting member 4 is preferably made of a strong material with high elastic restoring force, and may be made of not only metal such as stainless steel but also synthetic resin. Moreover, since the clamping tongue piece 4c is curved in an arc shape as described above, the above-mentioned connection can be easily performed. In addition, it is preferable to use a plurality of the above-mentioned connecting pieces 4 when connecting.

After the connection is made as described above, the opposite outer protruding edge 2c of the one of the connected plates 2 is fixed to the body rim 7 with screws 6 or the like. From then on,
They can be connected sequentially using the same procedure.

In addition, in order to further strengthen the connection strength during the above connection, the overlapping surfaces 1e and 2e of the inner and outer protruding edges 1a and 2a and the surface of the furring edge 7 for attaching these are provided. Alternatively, an adhesive may be applied to the substrates and the substrates may be bonded and integrated with each other via the adhesive layer.

Further, the connecting member 4 does not necessarily have to have a specific shape as shown in the above embodiment, and it also needs to be manufactured by processing a single plate-shaped material. There isn't. In short, the connecting member 4 has a base end 5 that is generally U-shaped in side view, extends from the base end side of the outer abutment piece 4b of the base end 5 to the opposite side, and has an inner bulge. Any other design changes are allowed as long as the clamping tongue piece 4c is bent into a shape.

Furthermore, the present invention is not limited to the case where joints are formed in the connecting portions as described above, but can also be applied to cases where there is no joint.

Effects of the Invention As mentioned above, the present invention does not use nails for temporary joining as in the past when connecting the plates, and therefore not only does it prevent the formation of nail holes after the nails are removed, but also Since the connecting member is not exposed to the outside, the appearance does not deteriorate in the finished state.

In addition, it is possible to omit the conventional work of filling with putty or the like to make the nail holes inconspicuous, and it is also possible to forcibly fit one plate to one side edge of the other plate when joining. Since they can be connected in a matching manner, the operation can be performed extremely easily and reliably, and the on-site workability can be improved.
