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) For example, in a prefabricated soundproof room, panels,
It is desirable to reduce the number of parts by keeping the parts of the same standard, but in the case of a planar connection in which the sides of the panels are butted together and connected in a flat manner, conventionally, the front or back side of the joint surface, or the front and back sides are made of wood or metal plates, etc. means for connecting with screws and nuts via
This is done by connecting with dowels, tenons, etc.

In addition, when connecting the corners by butting the end faces of the panels at right angles, it is necessary to use a member different from that used for planar connections, such as L-shaped metal fittings, to process the panels separately, or to facilitate separate panels for the corners. be.

In any case, the disadvantage is that the number of parts, the number of packaging items during transportation, and the number of assembly steps increase.

(Purpose of the invention) This invention was made in view of the above points,
It is an object of the present invention to provide a panel connecting device that can reliably and closely connect a plane connection and a corner connection of panels using the same member and improve assembly accuracy and work.

(Embodiment of the invention) FIG. 1 shows a connecting device according to an embodiment of the invention, and is a plan view of a state in which a first panel A and a second panel B are connected in a plane. Approximately U-shaped grooves 1 are provided at the upper end surfaces of the first panel A and the second panel B, and the panel thickness T
A bolt hole 2 passing through the side wall of the groove 1 is provided at a position of 1/2T.

Reference numeral 3 designates a connector, which is L-shaped and made of metal or synthetic resin, as shown in FIG. A second connecting hole 3b is provided at a position 1/2T of the panel thickness T from the bent end.

Note that 3c and 3d are mounting holes.

The second connecting holes 3b of this connecting tool 3 are connected to the first connecting holes 3b, respectively.
The second panel A and the second panel B are attached to the same positions as the bolt holes 2 through attachment holes 3c and 3d.

Therefore, in the case of planar connection between the side surface of the first panel A and the side surface of the second panel B, the opposing connectors 3 are inserted through the bolts 4 into the respective first connection holes 3a and then tightened with the nuts 5. A flat panel can be obtained just by fastening.

In the case of corner connection between the back surface of the first panel A and the side surface of the second panel, the first panel
Bolt hole 2 provided in panel A and second panel B
Align the first connection hole 3a of the connection tool 3 attached to the panel A with the first connection hole 3a and the second connection hole 3b of the connection tool 3 of the first panel A through the bolt hole 2. By passing the bolt 4 through the bolt 4 and fastening the connector 3 of the first panel A and the second panel B with the bolt 4 and nut 5, a corner-connected panel is obtained.

FIG. 4 shows another embodiment of the connector 3, which is approximately box-shaped and has a second connecting hole 3b at the same position on the opposite side.

(Effects of the invention) As described above, according to this invention, the panel only needs to have grooves and bolt holes at the same positions on the left and right sides, and the connectors can have the same shape, so it has the advantage that products of the same standard can be used. This reduces the number of parts and eliminates confusion during assembly.
It is extremely useful for connecting assembled panels.
