DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention corrects a step between panels generated when a building panel used for a partition wall or the like is installed in a room of a high-rise apartment house or hotel, and aligns the panels. And a method of correcting a step between panels for accurately performing the step.

[0002]

2. Description of the Related Art In recent years, with the rise of buildings, the construction of wall surfaces using lightweight panels that do not require studs has been widely performed. When this lightweight panel is used, it is extremely difficult to finish the wall surface to be completely coplanar in terms of manufacturing, and in reality, it is actually slightly warped or curved within an allowable range for use. In the construction of these lightweight panels, the panels are supported at the upper and lower portions by panel support fittings fixed to the upper and lower slabs. Therefore, adjacent panels are clearly joined at the upper and lower portions at the wall end portions, but at the central portion in the vertical direction of the panel, there may be some level difference at the joined end portions.

As a device and a method for eliminating such a step, for example, a step correcting tool for a building panel and a step correcting method described in Japanese Patent Application Laid-Open No. 5-202617 have been proposed. The step correcting device for a building panel described in this publication sucks a suction pad to each of a pair of panels having a step, pulls up a recessed panel with a supporting member as a fulcrum, or presses a protruding panel. The step is eliminated. In this technique, as shown in FIG. 7, an architectural panel in which an end face of a panel joint is flat is targeted.

On the other hand, as shown in FIG. 6, a panel having a structure in which end surfaces of joints are fitted to each other is often used for a building panel used for a partition or an outer wall. In the case of a panel that is slightly warped or curved, although it is practically acceptable, move one panel horizontally while maintaining the state where the step is corrected, and fit the fitting parts of adjacent panels It was necessary to construct.

[0005]

However, in the conventional step correcting tool 100 shown in FIG. 8, the first and second suction members are held by the integral frame 101, so that the panel B is held in the sucked state. You cannot move horizontally. Therefore, when constructing a distorted panel, the fitting portion of the panel is fitted while correcting the step by pushing the panel from the front and back surfaces with a plurality of hands. Furthermore, like the double-walled structure, when the construction of the other side is performed after the completion of the construction on one side, the one that can be corrected by pressing from the front side is good, but when it is necessary to press from the back side, it is already Since the one-sided operation has been completed, it cannot be pushed from the back side. Therefore, as shown in FIG. 9, a method of fixing the contact plate on the convex surface side and pulling up the concave side with the tapping screw 120 based on the contact plate 121 can be considered. However, even in this method, the pulled-up state is maintained. The panel cannot be moved horizontally. for that reason,
In order to avoid such a step correcting operation, it is necessary to significantly improve the accuracy of the panel itself, and as a result, the yield is reduced and the cost is increased.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to correct and join steps of slightly warped or curved adjacent panels when constructing a building panel having a fitting structure at a joint. It is an object of the present invention to provide a step correcting tool and a step correcting method for a building panel.

A suction pad 16 is attached to the first suction pad section 14. The suction pad 16 is not a special one but a general-purpose general-purpose product having an appropriate size. The suction pad 16 is provided with a suction port 161 for sucking air inside, and is connected to a suction machine (not shown) by a suction hose (not shown) or the like.

Reference numeral 15 denotes a second suction pad portion, which comprises a suction pad 16 and a screw bolt (mounting shaft) 18 having a handle 17 for moving the suction pad 16 back and forth. The second suction pad section 15 is connected to the first suction pad section 1 of the frame 10.
The suction pad 16 is provided at an end opposite to the side 4 and functions to suck one of the pair of wall surfaces with the suction pad 16 and to lift the one in a direction perpendicular to the wall surface. An extendable portion 19 is provided between the second suction pad 15 of the frame 10 and the support member 13. The expansion / contraction part 19 moves the second suction pad part 15 in the horizontal direction (the direction of the arrow in the figure). The distance that the second suction pad section 15 moves by the expansion and contraction section 19 is approximately 20 mm. In this embodiment, the operator manually moves the second suction pad section 15. The mechanism may be operated by a handle or the like. As described above, a method of moving the second suction pad unit 15 by the expansion and contraction unit 19 may be selected from various moving mechanisms and used.

Next, a method of correcting a step using the step correcting tool 50 will be described with reference to FIGS. In FIG. 2, the building panels A and B are installed with their ends abutting each other at a position where a step 22 is formed. A concave portion is formed on the panel A side and a convex portion is formed on the panel B side, and these two panels are fitted to each other so that they can be firmly connected to each other.

Here, the first suction pad portion 14 of the step correction tool 50 is positioned on the panel A, and the support member 13 is positioned near the end of the panel A (boundary with the panel B having a step). Deploy. Then, set a switch (not shown) to O
N, the panel A is sucked by the suction pad 16 of the first suction pad section 14, and the level difference correcting tool 50 is held. At this time, the contact support plate 131 of the support member 13 is slightly projected from the end of the panel A toward the panel B. This is because when the panel B on the depressed side is pulled up, if the panel B is pulled up until it is hooked on the contact support plate 131, the two panels are flat. This is particularly effective when the ends of both panels A and B are flat.

Next, the handle 17 of the second suction pad section 15 is operated to press the suction pad 16 interlocked with the handle 17 against the panel B, and a switch (not shown) is turned on to perform suction. Then, the suction pad 16 is pulled up to the frame 10 side by operating the handle 17 so that the panel B
Pull up. This lifting operation is performed until the panel B comes into contact with the contact support plate 131 or reaches the same height. FIG. 3 shows a state in which the panel B is pulled up. Thereafter, the second suction pad portion 15 is pushed in the direction of the support member 13 to contract the expansion / contraction portion 19, whereby the concave portion of the panel A and the convex portion of the panel B can be accurately engaged as shown in FIG. it can.

Then, a tapping screw is screwed into the joint surface between the panels A and B and fixed. At this time, panel A
A tapping screw may be screwed obliquely in the direction of panel B from the side and fixed. Finally, the switch of the step correction tool 50 (not shown) is turned off, and both suction pads 1 are turned off.
6 is released, and the step correction tool 50 is attached to the panel A,
Remove from B and finish the work. According to the first embodiment, since the panel B can be moved horizontally while holding the step correcting tool 50, the step 22 can be corrected by a series of operations, and the panels A and B can be accurately engaged. Can be.
