Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a device for connecting panels of prefabricated simple houses, soundproof rooms, etc.

(Prior art) Conventionally, methods for connecting the side surfaces of multiple panels abutting each other include connecting wooden or metal plates from the front or back sides of the joint surfaces, the front and back sides using screws or nuts, or using dowels or tenons. Methods of connecting with sets, etc. are used, but when connecting with screws, nuts, etc., the airtightness of the connecting surface is maintained, but there are screws, nuts, etc. on the surface.
Nuts, etc. are exposed, spoiling the appearance, and a fastening tool is required during assembly. In addition, dowels, tenons, etc. maintain the beauty and airtightness of the connecting surfaces, but it is necessary to machine one end of the joint surface into a concave shape and the other end into a convex shape, which requires high processing accuracy and requires disassembly. When transporting it, there is a risk of damaging the protrusion.

(Purpose of the invention) This invention was created in view of the above points, and aims to improve assembly accuracy and work by tightly connecting the front and back surfaces with one touch without damaging the aesthetic appearance of the front and back surfaces of the connection. The purpose of this invention is to provide a panel connecting device that allows for

(Embodiment of the invention) Fig. 1 shows a perspective view of a panel connecting device according to an embodiment of the invention, in which concave grooves 1 and 1' are provided in the upper end surfaces of panels A and B, respectively. There is. 2 and 2' are connection screws, and as shown in Fig. 2, a seat 2c is provided at a position one step lower than the neck 2b of the screw head 2a, and is attached at the same position on the sides of panels A and B. It is worn. Reference numeral 3 denotes a connector, which is approximately U-shaped and made of metal or synthetic resin, as shown in FIG. A keyhole-shaped fitting hole 4 having a round hole portion 4a and a groove 4b slightly wider than the neck portion 2b of the connecting screws 2, 2' is provided above the hole portion 4a, and the connecting hole 4 is provided in the center of the vertical piece on the other side. A deep groove-shaped notch 5 is provided which is slightly wider than the neck portion 2b of the screw 2, 2', and the upper end thereof is inclined outward.

The panel connecting device constructed in this way will be described below according to the assembly procedure. As shown in FIG. It fits into the neck part 2b through the head part 2a.

Next, when the side surface of panel B is brought down from above with the side surface of panel B in contact with the side surface of panel A, the neck portion 2b of the connecting screw 2' attached to panel B is inserted into the notch 5 of the connector 3. When lowered further, the head 2a of the connecting screw 2' is fitted into the notch 5 along the slope of the connecting tool 3, and the head 2a of the connecting screw 2 of panel A and the head 2a of the connecting screw 2' of panel B are inserted. The elastic force of the connecting tool 3 causes the panels A and B to be tightly connected by pulling each other.

Note that the concave grooves 1 and 1' provided in the panels A and B may be provided along the entire length of the panel side surface, and
In order to improve the stability of the panel A, the concave groove 1 of the panel A may be made shallower as shown by the dotted line in FIG.

Additionally, a flange may be provided on the vertical piece of the connector 3 for reinforcement.

Fig. 5 shows another embodiment of this invention, in which concave grooves 1 and 1' are provided over the entire length of the sides of panels A and B, and connecting screws 2 and 2' are installed in three places to connect them. They are connected using tool 3. In addition, in the same figure, if connecting screws 2 and 2' are installed in two places, upper and lower, and a plate is inserted into the grooves 1 and 1' between them, and connected with a connecting tool 3, even more airtightness can be obtained. Of course.

(Effects of the invention) As described above, according to this invention, panels of the same standard can be processed by simply providing grooves at the same positions on the left and right sides and planting connecting screws at predetermined positions. The connecting screws are located inside the grooves and do not protrude from the side of the panel, and there is no risk of them bending or breaking during transportation. During assembly, the connecting tool only needs to be inserted into the connecting screws. Since no tools are required, it is possible to reliably and closely connect the front and back surfaces of the panel connecting portions with a single touch without damaging the appearance of the front and back surfaces, making it extremely useful for closely connecting panels.
