Description

[Detailed Description of the Invention] The present invention relates to a device for connecting panels, and more particularly, to a device for connecting panels having groove-shaped members that open outward at the edges. To easily connect panels without modifying the panels themselves and without creating a step between the panels.

Conventionally, this type of panel connection uses a U-shaped connecting piece 1 and a connecting pin 2, as shown in FIGS. Fit the joining piece 1, weld it to the groove-shaped material 4 at 5 parts, and then pass the joining pin 2 through the through hole 7 of one of the joining pieces 1, and connect the protrusion 8 at the rear end of the joining pin 2 to the bottom piece of the groove-shaped material 4. The connecting pin 2 is fitted and fixed into a mounting hole 9 drilled in the hole 9, and the tapered part 10 at the tip of the connecting pin 2 is driven into the through hole 7 of the other connecting piece 1. It is difficult to connect the panels for two reasons: welding distortion occurs when welding to the shape material 4, and the accuracy of hole machining between the through hole 7 into which the connecting pin 2 is inserted and the mounting hole 9 is not accurate. was.

The present invention has been devised in view of the above points, and will be described in detail below based on the embodiments shown in the figures.

In the panel 3, a metal channel member 4 having a U-shaped cross section is fixed to the back side of the end of the panel 12 with an upper horizontal piece 13 with its opening facing outward, and the upper horizontal piece 13 and the lower horizontal piece 14 are attached to the panel 3. It is made to protrude outward from 12.

As shown in FIG. 7, the connector 16 is formed into a shape having U-shaped portions 17. It is slanted to provide springiness in the vertical direction.

The connector 16a shown in FIG. 7a is formed by bending a single metal plate into a shape in which both sides share the top piece 18, and the connector 16b shown in FIG. 7A is a U-shaped member. 22 is formed by fixing a vertical piece of U-shaped material to the outer surface of each side of the member 22.

The connector 16 formed in this way has the U-shaped portions 17 at both ends inserted into the respective groove members 4 of the opposing panels 3, and each lower piece 19 of the U-shaped portion 17 By coming into elastic contact with each of the lower horizontal pieces 14 of the groove-shaped members 4, each horizontal upper piece 18 comes into pressure contact with the lower surface of the upper horizontal pieces 13, respectively, so that the connectors 16 are difficult to remove and are attached to each of the groove-shaped members 4. After this, a screw 25 such as a tapping screw is inserted into each groove-shaped member 4.
The upper horizontal piece 13 is screwed into each upper piece 18 to connect the two, and a batten 26 is housed between the facings 12, 12 of both panels 3.3 to make the surfaces of the panels 3 flush. It is something.

In the embodiment shown in FIG. 6, another panel can be connected to the connecting portion of the panels 3, 3 in a T-shape by using a U-shaped member 22 that connects the panels 3, 3 to each other.

As described above, the present invention connects both panels by fitting the U-shaped parts on both sides of the connector into the groove-shaped material provided at the end of the panel.
The panels can be connected by using a single connector, and the upper and lower pieces of each U-shaped part are pressed against the upper and lower horizontal pieces of each channel member, respectively, by spring force. Therefore, there is no deviation in the surface direction of both panels, and the upper horizontal piece and the upper piece are joined with screws with the surfaces of both panels flush in this way. , the two can be reliably connected flush.
