Description

[Detailed Description of the Invention] The present invention relates to a building panel pulling jig, and more specifically, the legs of two driving pieces pivotally supported by a fastener to a joint fitting have driving teeth at their tips. Moreover, since the opposing inner surfaces of the legs have a slope that widens toward the tip, the legs of the metal fittings can be driven across the bifurcated panels to be joined. The panels are drawn together to further strengthen the pressure contact between both panels, and at least one of the legs is pivotable inward, so multiple pulling jigs according to the present invention can be installed at the same panel joint. This makes it possible to drive several pulling jigs in close proximity without causing any inconvenience such as the previously driven pulling jigs interfering with the panel pulling action of newly driven metal fittings. This article relates to building panel pulling jigs.

Conventionally, the panels that make up a building are joined together using nails or adhesives, and in this joining process, if the panels are not in close contact with each other, sufficient joint strength cannot be ensured by the nails or adhesives. That is, if there is any gap between the panels, external force will be transmitted through the small diameter of the nail, causing a problem. Further, due to this gap, there has been a problem that the bonding strength of the adhesive cannot be achieved. For that reason,
For example, when assembling a building using wood-based panels, the panels are pressed together using wire or a simmerer such as a vise to prevent gaps from forming at the joint surfaces.

This invention was devised in view of the above problems, and its purpose is to easily bring the panels into close contact with each other by having the two panels that connect the legs straddle each other and driving their teeth. Moreover, it is an object of the present invention to provide a panel pulling jig in which even if a plurality of panel pulling jigs are used at the same joint part, the pulling jig driven in earlier does not interfere with the pulling action of the metal fittings driven in later.
In order to achieve this purpose, the present invention has two legs with driven teeth at their tips, and a slope on the opposing inner surfaces of the legs so that the legs become narrower as they approach the teeth. The general outline is that at least one of the parts can be rotated inward.

The pulling jig according to the present invention will be explained below with reference to the attached drawings.

FIG. 1 is an overall perspective view of a panel pulling jig 1 according to the present invention. This panel pulling jig 1 consists of a U-shaped fitting 2 and two driving pieces 3 and 4. Sharp driving tooth portions 32, 42 are provided at the tips of the leg portions 31, 41 of both driving pieces 3, 4.

Further, the opposing inner surfaces 33, 43 are sloped so that the leg portions 31, 41 become narrower as they approach the driving tooth portion. In other words, the opposing inner surfaces 33 and 4
3 is expanded toward the respective driving teeth 32, 42, and the opposing sides 35, 45 of the driving pieces 3, 4 are brought into contact with each other to form a wedge shape with a constant width. .

On the other hand, the approximately U-shaped fitting 2 has an opening O on one side, and a pull-out recess 21 at the lower end.
When pulling out the drawing jig 1 from the panel, a crowbar or the like can be inserted into the drawing recess 21 and pulled out.

FIG. 2 is an explanatory view showing that at least one of the driving pieces 3 and 4 of the drawing jig is rotatable inwardly. Both driving pieces 3 and 4 are attached to the fitting 2 via pins 5 and 6, but the piece 3 that is in contact with the side wall 22 is blocked by the side wall 22 of the fitting 2 and cannot pivot. On the other hand,
The driving tooth portion 42 of the piece 4 on the side of the opening O can be rotated about the pin 6 in a direction approaching the driving tooth portion 32 of the piece 3 (as shown by the two-dot chain line in the figure). As shown in the figure, when it functions as a wedge shape with a constant width, the side surfaces 35 and 45 above the pins 5 and 6 are in contact, and the teeth 42 of the driving piece 4 are close to the teeth 32 of the other piece. When rotating in the direction, the side surfaces 35 and 46 between the pins 5 and 6 abut.

FIG. 3 is an explanatory view showing how the panel pulling jig 1 described above is used. When joining the side edges of panels A and B, depending on how the panels A and B are arranged, it may not be possible to apply sufficient pressure in the direction perpendicular to the joining surfaces, resulting in a gap C. In order to close this gap C, the panel pulling jig 1 according to the present invention is driven into the frame timber edges A ₁ and B ₁ of panels A and B in a state spanning the gap C, that is, the driving pieces 3, If the heads 34, 44 of 4 are hit with a hammer or the like and driven in the direction of the arrow, the legs will be driven into the frame timber ends A ₁ , B ₁ by the driving teeth 32, 42. leg portion 31,
41 is driven into the frame lumber ends A ₁ and B ₁ , the driven piece 3,
The opposing side surfaces 35, 45 of 4 are in contact with each other. Therefore, the opposing inner surfaces 33, 34 form a wedge shape that widens to a certain width toward the driven tooth portions 32, 42, and due to this wedge effect, the panels A, B are gradually drawn together using the opposing inner surfaces 33, 43 as a guide. Finally, the gap C is closed and the panels A and B are brought into close contact with each other.

In addition, this pulling jig should be driven into panels A and B.
If this is done before the lower end surfaces of the panels are fixed, the movement of both panels will not be restricted and the pulling effect can be fully exerted.

In addition, when actually using the proposed pulling jig 1,
In normal cases, simply driving in the original pulling jig 1 will pull the panel firmly enough, but depending on the size of the panel and the width of the gap, it may be necessary to drive in several original pulling jigs. There are times when it is necessary not to do so. In other words, there are cases where the gap between the panels is not completely closed even if sufficient driving is performed using one pulling jig. Even in such a case, according to the pulling jig of the present invention, in the pulling jig 1 that has already been driven, as the panels A and B are pulled together, the driving piece 4 is centered around the pin 6 (with the side surface 35). 45 as a fulcrum) (see Fig. 2). Therefore, the pulling action of the metal fittings being driven is not hindered.

FIG. 4 is an explanatory diagram of a state in which a panel gap is closed using a plurality of pulling jigs according to the present invention.

That is, as explained with reference to FIG. 3, even if the pulling jig 1 is driven into the edges A ₁ and B ₁ of the frame materials of panels A and B, the gap is not completely closed and a gap C' remains. In this state, separate the pulling jig 11 into the frame lumber.
If it is driven into A ₁ and B ₁ , the wedge effect of the pulling jig 11 will pull the panels A and B together, and the gap C' will be closed without any interference from the pulling jig 1. In this case, if the gap C' is still not closed, a separate pulling jig can be driven in again to close the gap. On the other hand, if the panel pulling jig of the present invention is used as an auxiliary after the panels have been pressed together using a simmerer or the like, even closer contact can be achieved.

When panels A and B are drawn together and brought into close contact as described above, a crowbar or the like is inserted between the pull-out recess 21 provided at the lower end of the approximately U-shaped fitting 2 and the end surface of the panel. If lifted upward, the pulling jig 1 can be easily pulled out from the panel.

Although the above embodiment describes the case of butt-joining wall panels, the panel pulling jig of the present invention is not limited to this, and can also be used to close horizontal gaps between installed floor panels. It will be done.

As described above, by driving the panel pulling jig of the present invention across the gap between panels, it is possible to close the gap and bring the panels into close contact with each other, thereby ensuring sufficient bonding strength between the panels. can be obtained.

Moreover, by using multiple pulling jigs of the present invention at the same joint, the gap can be completely closed, and by using the pulling jigs of the present invention, buildings with large structural strength can be constructed. I can do it.

Furthermore, since the pulling jig itself is durable enough to withstand repeated use, the panel pulling jig of the present invention is highly effective both technically and economically.
