Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel connector for joining two panels.

Conventionally, bolts and nuts have been used as panel connectors for joints where two panels overlap.
That is, a required number of bolt insertion holes are drilled at appropriate intervals in the panel joint, and bolts are inserted through the holes and tightened with nuts. Therefore, it is necessary to tighten the nuts by inserting hands from both sides of the panel, which not only takes time, but also tends to cause the nuts to be tightened to varying degrees, resulting in uneven loads on the bolts, which can lead to long-term use. There were also problems with durability.

In view of these circumstances, it is an object of the present invention to provide a panel joining tool that can join panels reliably and firmly, even though joining the panels is very simple.

The feature of the panel jointer of this invention is that both sides of a vertically flat plate are folded in the same direction, leaving the base plate, and then the ends of the folded sides are folded back outward into a substantially U-shape and held in place. a stop having a hole in the center of the base plate;
It consists of a bolt, and the bolt is screwed into the hole of this stopper.

Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, A is a stopper which is used to fold a vertically long flat plate with both side parts 2, 2 in the same direction, leaving the base plate part 1 intact. Although the bent portions 3, 3 at this time are U-shaped in the drawing, they may be bent V-shaped. Next, the tip portions of the folded side portions 2, 2 are each folded back outward into a substantially U-shape to form the holding portions 4, 4. The shape of the holding parts 4, 4 is not limited to the substantially U-shape, but may be V-shape. Furthermore, the clamping parts 4, 4
If the tips are bent outward, they will serve as guide pieces 6, 6 when inserting the panel, allowing smooth insertion. Further, in the center of the substrate portion 1, a hole 7 is provided with a thread formed on the inner surface. 10
is a bolt. In addition, the interval X between the upper and lower holding parts 4, 4
is formed to be narrower than the diameter Y of the bolt, and the distance Z between the tips of the upper and lower holding parts 4, 4 is the same as or slightly narrower than the vertical or horizontal distance W of the holes 11, 11 formed in the panel. put. Reference numerals 11 and 11 indicate a plurality of holes bored at appropriate intervals at the joint between the two panels 12 and 12. The shapes of the holes 11, 11 are preferably rectangular, and the distance W between the two opposing sides is the same as or slightly wider than the distance Z between the tips of the upper and lower holding parts 4, 4, as described above. Also holes 11,1
The shape of 1 may be rectangular, hexagonal, etc. as necessary, as long as the distance W between the two opposing sides satisfies the above conditions.

The panel connector of the present invention having such a configuration is attached by inserting the fastener A into the holes 11, 11 drilled in the joint between the two panels 12, 12, and then clamping the fastener A to the clamping portion 4,
The clamping portions 4 are inserted from the tips 6, 6 side until the inner surfaces 4a, 4a of the clamping portions 4, 4 come into contact with the appropriate peripheral positions of the holes 11, 11 of the panels 12, 12. In this state, the bolts 10 are screwed into the holes 7 of the base plate portion 1 from the base plate portion 1 side to complete the joining and fixing.
When the bolt 10 is screwed into the hole 14, the tip 13 of the bolt 10 forcibly moves the clamping portions 4, 4 up and down (in the Q and R directions in FIG. 3).
As a result, the peripheral portions of the holes 11, 11 of the panels 12, 12 contact the inner surfaces 4a,
4a and is guided into the clamping portions 4, 4 by the guide pieces 6, 6, so that the two panels 12, 12
It is to be noted that the panel connector can be attached not only in the vertical direction but also in the horizontal direction.

As explained above, according to the panel joining tool of the present invention, compared to conventional joining using bolts and nuts, construction can be performed from one side of the panel, making the construction work easier and completed in a shorter time. Moreover, reliable and strong bonding can be achieved. Moreover, since it is such a simple work, uniform construction accuracy can always be obtained regardless of the skill level of the builder. Furthermore, since uniform construction accuracy can be obtained in this way, the load applied to each joint part of the panel joint part is equalized, and joint fixation with excellent durability can be achieved.
