Description

[Detailed Description of the Invention] The present invention relates to a panel warpage correction device used when assembling panels along support columns.

For example, in prefabricated buildings, the side edges of thicker panels are often assembled along support columns. Since the above-mentioned support is usually made of a light steel tube in the shape of a rectangular tube, there is no warpage and there is little deviation in accuracy. However, panels are made of wood, for example, and have a very large area compared to their wall thickness, so they often warp. As a result, the assembly accuracy is poor and the appearance is also very poor. Conventionally,
At most, the warp in the panel is removed before assembly, but the warp returns again during assembly. For this reason, some means was needed to eliminate warpage during assembly.

The present invention was devised in view of the above circumstances, and its purpose is to provide a relatively simple structure, but to be able to install thicker panels in parallel with the support columns. It is an object of the present invention to provide a panel warpage correction device that can reliably remove and correct warpage of a panel.

An embodiment of the present invention will be described below based on the drawings. In the figure, reference numeral 1 is a rectangular cylindrical support made of, for example, a lightweight steel pipe, and this can be considered as having no warpage or distortion. Reference numeral 2 denotes a panel formed by adhering a wooden surface board 4 such as veneer plywood to a wooden frame 3, for example. This panel 2 is thicker than the pillar 1, and is attached along both sides by means not shown.
Due to its structure, it has a warp that bulges out on one side of the support column 1, for example. This warp is corrected by a warp correction device S comprising a main metal piece 5 inserted between the support column 1 and the side end face of the panel 2 and a secondary metal piece 6 that can be engaged with the main metal piece 5.

That is, the main hardware 5 is made of a substantially rectangular metal plate, and its vertical dimensions may be arbitrary as shown in the figure. The longitudinal dimension is longer than the wall thickness dimension of the panel 2. One end in the longitudinal direction of the main metal part 5 is provided with a notch that divides it into two vertically, and only one piece along the notch is bent at a substantially right angle. The bent piece is made into a hooking piece part 7, and the remaining piece which is not bent is made into a fixing piece part 9 having a nail hole 8. Further, a circular tool-hanging hole 10 and a rectangular mounting hole 11 are formed inside the circular tool-hanging hole 10 at the other end in the longitudinal direction of the main hardware 5. The distance between the mounting hole 11 and the engaging piece 7 is the same as the depth of the support 1. Therefore, the tool hanging hole 10 is connected to the support 1.
and is bored at a position protruding from the panel 2. The secondary metal part 6 is made of a rectangular metal plate that can be engaged with the attachment hole 11 of the main metal part 5, and has a joint surface 6a on one side thereof to be joined to the surfaces of the support column 1 and the panel 2. A nail hole 12 is bored at one end in the longitudinal direction.

The warpage correction device S constructed in this way is assembled by means as shown in FIG. 4. That is, the panel 2 is fixed by means not shown with its side end surface along the support column. At this time, one surface of the panel 2 is made to protrude from one surface of the support column 1, and the other surface of the panel 2 is flush with the other surface of the support column 1. As shown in FIG. 4A, when the panel 2 is arranged in parallel with the support 1, the main metal part 5 is forcibly inserted between the support 1 and the side end surface of the panel 2. At this time, the hooking piece 7 at one end of the main hardware is engaged with one side of the support 1, the fixing piece 9 is in contact with the side end surface of the panel 2, and the tool hanging hole 10 at the other end is connected to the support 1. The mounting hole 11 protrudes toward the other surface of the panel 2 and is flush with the other surface of the support column 1 . If panel 2 is not warped, nail hole 8
The fixing piece 9 and the panel 2 are fixed by shooting a nail 13, which is a fixing tool, into the side end surface of the panel 2 which projects upwardly from one side of the support 1. If the panel 2 is warped, it is natural that the warp must be corrected. The problem here is the direction of the warp, but as shown in the figure, the fixing piece 9 is warped in the direction protruding from one side of the panel 2, that is, the panel 2 is bulged and warped toward the other side of the support 1. In this case, it is impossible to drive the nail 13 into the nail hole 8.

In this case, as shown in FIG. 4B, for example, a rod-shaped tool 14 with a curved tip is inserted into the tool-latching hole 10 of the main metal part 5 at a position protruding from the support 1 and the panel 2. The curved portion is brought into contact with the panel 2. A force in the opposite direction to the warp is applied to the panel 2 by lever action utilizing this curved shape to correct the warp. Then, when the side end surface of the panel 2 and the edge of the fixed piece part 9 are aligned, that is, the other side of the panel 2 and the support 1 are aligned, nails 13 are driven into the nail holes 8 while maintaining this position. to maintain the position of panel 2. Conversely, if the panel 2 is warped protruding from the edge of the fixed piece 9, that is, if the panel 2 bulges out to one side of the support 1 and is warped, first
Align the edge of the fixing piece part 9 with the edge of the side end surface of the panel 2 by shifting. Next, pass the nail 13 through the nail hole 8.
After fixing the fixing piece part 9 and the panel 2 by hammering them together, the tool 14 is inserted into the tool-latching hole 10 to urge the panel 2 in the direction opposite to the warp. That is,
Using the support 1 as a fulcrum, the tool 14 urges the panel 2 to the other side of the support 1 through the main hardware 5, so that the hooking piece 7 of the main hardware 5 is hooked to one side of the support 1, and the mounting hole 11 is attached to the support 1. Align it the same as the other side. From this state, as shown in FIG. 4C, the mounting hole 11 of the main metal part 5 is
A secondary metal piece 6 is inserted and engaged, and its joining surface 6a is brought into contact with and joined to the other surfaces of the support column 1 and the panel 2, respectively.

In this way, the main hardware 5 holds the column between its hooking piece 7 and the joint surface 6a of the secondary metal 6, and also holds the panel 2 between the fixed piece 9 and the secondary metal 6.
are fixed, the main metal part 5 and the secondary metal part 6 generate a force to prevent the panel 2 from warping with respect to the support 1, and the warp of the panel 2 can be corrected.
Finally, as shown in FIG. 4D, from the main hardware 5 to the tool 1
4 and bend the protruding end of the main hardware 5 so that it does not get in the way and does not spoil the aesthetic appearance.

Note that it is not always necessary to use a tool 14 with a curved tip; for example, even if the tip is straight, it can be inserted into the tool hanging hole 10.
The warp of the panel 2 can be corrected by inserting it into the panel 2 and bringing the end into contact with the panel 2, and levering the main metal fitting 5 as a fulcrum.

As explained above, according to the present invention, the side end surface of the support is aligned with the support, and one of the side end surfaces is placed between the side end surface of the support and a panel that is thicker than the support that is juxtaposed and protrudes from the support. One end of the main hardware to be inserted is provided with a fixing piece for fixing the side end surface of the panel that protrudes from the support and a bent hooking piece that engages with the support, and the other end is provided that protrudes from the support and the panel. Drill a hole for hanging a tool to press the panel in the direction opposite to the warping of the panel at this position, and a mounting hole inside this hole at a position spaced from the engaging piece by the same width as the depth of the column. At the same time, the secondary metal member that can be engaged with the mounting hole is provided with a joint surface that joins with the above-mentioned support column and panel. Therefore, the main hardware holds the support between its hooking piece and the joint surface of the secondary metal, fixes the panel with its fixing piece and the joint, and prevents the panel from warping with the support as a reference. You can keep it straightened. The fixing piece and the mounting hole serve as a guide when straightening the panel, and there is no exposed object on one side of the panel. Therefore, even after assembling a thicker panel to the support, the warpage of the panel can be corrected very easily and reliably, and the workability is good and the interior base material can be attached to the panel. Since there are no protrusions on the sides, the device has an excellent appearance, and the device itself has a very simple structure and can be provided at a low price.
