Description

[Detailed Description of the Invention] The present invention relates to a wall panel joining device that is equipped with a joining fitting having a spacer protruding from the inner surface of a jointer, and that can improve the efficiency and reliability of wall panel joining work.

For example, Japanese Utility Model Application No. 53-83817 discloses a method for covering the joints that occur between wall panels in buildings using dry construction methods using panels, which are inserted into the joints and connected to the wall panel frame material by bolts. A structure is disclosed in which a hook-like object covering a joint is drawn to a wall surface using a hook member provided on a spacer-like object.

However, this requires two members, one in the form of a spacer and the other in the form of a jointer, and all the spacers must be aligned with the through holes in the wall panel frame material and bolted together. Furthermore, after installation, the frame material is fixed by tightening bolts and nuts, such as tilting a spacer-like object by rotating the bolt and pulling a jointer-like object with a hook member, and turning the bolt to pull it. Since the bolts have to be moved at the same time, delicate adjustments are required to tighten the bolts, resulting in poor workability.

The object of the present invention is to provide a wall panel joining device that can solve the above-mentioned problems by attaching the jointer at the same time as the panels are connected.One embodiment of the present invention will be described below with reference to the drawings.

The joining fitting 1 that can be used in the device of the present invention is a steel plate having a U-shaped cross section with both sides bent at right angles, and a contact piece 3 that comes into contact with the outer surface of the panel P at the tip of the bent part.
The joint 2 is provided with a joint 2 formed with a
It is possible to straddle the gap g between the facing wall panel frame members F and F of the wall panel P, which is the joint part M between the wall panels P and P arranged in parallel. Further, on the inner surface of the bottom plate of the jointer 2, thin pieces 6 are provided at a total of three locations, i.e., the center and the top and bottom, and are provided with rectangular parallelepiped spacers 5 that extend inward and have a thickness T that is approximately equal to the gap g. Temporary fixing bolts 7, 7 are made to protrude in the same direction from their upper and lower ends at intervals, respectively. The temporary fixing bolt 7 has a length that extends inward beyond the back surface of the wall panel P when the contact piece 3 is in contact with the outer surface of the wall panel P. Further, the spacer 5 is provided with a vertically long through hole 8, and the frame members F and F of the wall panels P to be joined are provided with through holes 9 that can communicate with the through holes 8 of the spacer 5, respectively. I'll keep it. Note that 10a and 10b are bolts and nuts that are fixing devices 10, and only the exterior plate B is attached to the wall panel P.

However, the wall panel joining device 1 of the present invention has the second to fourth
As shown in the figure, a spacer 5 is inserted by inserting a thin piece 6 into the joint M between the wall panels P and P placed side by side, and the contact piece 3 of the jointer 2 is brought into contact with the outer surface of the wall panels P and P. As a result, the jointer 2 straddles the joint M. After that, as shown in Fig. 2, temporarily fastening bolts 7, 7 are screwed to the beam, base, etc. to temporarily fasten the upper and lower ends of the joining metal fitting 1.
Pull and bend the tip of the thin piece 6 to hang it on the frame material F, and then temporarily fix the center part of the jointer 2. At this time, make sure that the through hole 8 of the spacer 5 and each through hole 9 of the frame material F are concentric. becomes. After that, insert the bolt 10a into the through hole 9,
8 and 9 and screwed with nuts 10b, the frame member F of the wall panel P is clamped and fixed via the spacer 5 while maintaining the set gap g.

As mentioned above, the panel joining device of the present invention uses a joining fitting in which a jointer and a spacer protruding from the inner surface thereof are integrally formed, and a fixing tool. It can be installed correctly at the joint, reduces the number of parts compared to conventional products, and improves handling.
Not only can the number of man-hours for installing the wall panel be significantly reduced, but the number of screwing points can be reduced, making the installation reliable and easy, and the construction time can be shortened.Furthermore, since it has bolts 7 for temporary fixing, the joining fittings 1 can be easily installed. It can be temporarily fixed, and as in this embodiment, a thin piece 6 for bending can be attached to the spacer 5.
By attaching this, temporary fixing becomes easier.
