2. Description of the Related Art Tile-and-roofed roofs made of metal sheet have a better rain-repelling effect than flat-roofed roofs. Even if it is curved, it can be easily constructed, so it has been widely constructed in general houses, gymnasiums, warehouses and the like. As shown in FIG. 5, a general example of such a tiled roof is that a plurality of tiles 2 are fixed in parallel to a base plate 1 and a groove shape higher than the tiles 2 is provided between the respective tiles 2. Metal plate 3
Is arranged, and the grooved metal plate for cap 4 is placed on the tile rod 2.
And the both sides of the cap metal plate 4 are joined to the upper portions of the grooved metal plates 3 on both sides by goby joints (bottom seams). 2, facing downwards along the sides.

In this tiled roof, a painted metal plate is usually used for the grooved metal plate 3 and the metal plate 4 for the cap. In recent years, these methods have been replaced with new painted metal sheets without modifying the traditional roofing tiles, because they are inferior in durability and costly. A method of covering the entire roof is being studied.

As shown in FIG. 6, as shown in FIG. 6, a groove 6 capable of accommodating a tile rod is provided in a protruding manner, and both side walls of the groove 6 are provided with inwardly bent portions 7. 8 and concave streak 9
There is a method of covering a tiled roof with a covering metal plate 10 provided with. In this manner, the grooves 6 of the coating metal plate 10
The bent portion apex 11 of the side wall is made lower than the goby fold 5 of the tiled roof, and the interval between the bent portions apex 11 is set to the goby fold 5 on both sides.
If the distance is smaller than the distance, the top 11 of the bent portion engages with the lower end of the goby fold 5, as shown in FIG. 7, so that the coating metal plate 10 can be prevented from falling off. Further, since the ridges 8 and the recesses 9 are engaged with each other, it is possible to make the joint portion watertight.

In this coating method, the goby fold 5
In a state in which the outside of the roofing bar 2 faces downward along the side surface, the engagement with the bent portion apex 11 is shallow, and the groove 6 is easily detached from the roofing bar 2. It is necessary to raise the lower end of the goby fold 5 outward. However, conventionally, there has been no apparatus for continuously raising the lower end of the long goby fold 5, and it has been performed manually by using a bar or the like. However, there is a disadvantage that what is raised is not linear.

[0006]

SUMMARY OF THE INVENTION According to the present invention, in order to solve the above-mentioned disadvantages, a flange like a goby fold is efficiently provided.
The present invention also provides a straightening device that can be uniformly raised.

[0007]

According to a first aspect of the present invention, there is provided a flange straightening apparatus comprising: a roller; rotating shafts fixed to both sides of an eccentric position of the roller; It comprises a plate material suspended at its lower end and having a claw at the lower end, and a handle fixed to the outer periphery of the roller. The claws of both plate materials protrude inward at an acute angle, and the handle has a predetermined angle with respect to the rotation axis. It is characterized in that it is fixed at a position separated by a circumferential angle,
The flange straightening device of the second invention is characterized in that frames are inserted into both rotating shafts of the device of the first invention, and a guide roller is mounted between the frames.

[0008]

According to the first aspect of the present invention, since the plate material having the claw at the lower end is suspended on the rotating shaft fixed to both sides of the eccentric position of the roller, for example, when the rotating shaft is at the lowest position, for example, the metal plate is formed. When the roller is placed on a roofing rod on a roofing roof and the roller is rotated by a predetermined angle with a handle, the plate material is raised. Also, if the interval between the plate materials is wider than the width of the tile bar and narrower than the interval of the goby fold, and if the nail is inserted from the end of the tile bar so that the nail is below the goby fold, when the plate material rises, the nail will Go under the goby fold. At the time of this biting, since the nail protrudes inward at an acute angle, it causes goby fold outward. Therefore, when the rotary shaft is lowered most, the plate is inserted into the tile bar so that the claw tip of the plate material is below the goby fold and the roller is rotated by a predetermined angle, so that the goby fold is raised outward. In this state, if the handle is pushed or pulled and the roller is slid in the direction in which the tile rod extends, goby folding can be continuously caused. When the handle is fixed on the opposite side of the rotation axis with respect to the center of the roller, the rotation axis becomes the lowest when the handle is made vertical, and when the handle is pushed or pulled down in a direction that is easy to pull, the claws become goby. It digs under the fold and is easy to operate.

In the case of a tiled-roofed roof, the goby folds on both sides protrude upward, and there is a shallow groove between the two. Therefore, the width of the roller is made slightly smaller than the groove, and the roller slides in the groove. In the goby fold, the deformation resistance in the thickness direction is small. For this reason, if the handle oscillates left and right during the goose folding operation, the handle is deformed, and accordingly, the raised portion is wavy, and the engagement strength with the coating metal plate varies depending on the location. However, as in the second invention, if the width of the guide roller suspended between the frames is made slightly narrower than the groove on the upper side of the tile bar and the guide roller is moved in the groove, the lateral deflection of the handle can be reduced. It is prevented and the raised part becomes straight. Guide row
The roller may be mounted on one or both of the front and rear of the roller.

[0010]

1 and 2 show a flange straightening apparatus according to the present invention used for causing a goby-folding of a tiled roof made of a metal plate. A roller 12 has a hat-shaped outer peripheral surface. The width of the protruding portion at the center is the inside distance of the goby fold in the tiled roof. On both sides of the eccentric position of the roller 12, a rotating shaft 13 is fixed in a protruding state.
A frame 14 is inserted inside each rotating shaft 13, and a plate 16 having a claw 15 at the lower end is suspended outside the frame 14. The frame 14 is inserted into the rotary shaft 13 through a long hole 17 extending in the vertical direction, and can be moved up and down with respect to the rotary shaft 13. It is suspended so as not to be. A nut 18 is screwed onto the rotating shaft 13 outside the plate 16 to prevent the plate 16 from moving outward and maintain verticality. The claw 15 present at the lower end of the plate member 16 is formed such that the lower end is bent inward at an acute angle and is projected obliquely, and the thickness becomes thinner toward the upper end.

A handle 19 is fixed to the outer periphery of the roller 12. The handle 19 is fixed by screwing a base portion at a position opposite to the center of the roller 12 so that the handle 19 does not come off even when pulled.

A guide roller 20 is mounted on the frame 14 before and after the roller 12. This guide roller 2
0 has the same width and outer peripheral surface shape as the roller 12, and FIGS.
As shown in the figure, the interval between the goby folds 5 on both sides of the tile bar 2 is slightly narrower.

When the roller 12 or the guide roller 20 is inserted from the end of the roofing bar 2 so as to slide on the roofing bar 2 with the handle 19 upright, FIG.
As shown in the figure, the claw 15 of the plate 16 is located below the goby fold 5. However, when the handle 19 is tilted sideways, the plate 16 rises, so that the claws 15 bite into the goby fold 5 from below as shown in FIG. When this bite, Roller 1
Since the central projecting portion 2 prevents the inward deformation of the goby fold 5, the lower side of the goby fold 5 is raised outward. However, since the frame 14 is inserted into the rotating shaft 13 through the elongated hole 17, it does not rise and is in contact with the cap metal plate 4 of the tile bar 2. In this state, if the user pulls the handle 19 and moves the device in the direction in which the tile bar 2 extends, the device goes straight on the tile bar 2 while causing the goby fold 5.

[0014]

As described above, according to the flange straightening apparatus of the present invention, the plate having the claw at the lower end is suspended on both sides of the eccentric position of the roller, and the handle is fixed to the roller. By rotating the plate, the plate material is raised by the principle of leverage, so that the pawl bites into the lower side of the flange. Then, if the handle is pulled after the bite, the flange can be raised continuously. In addition, if a guide roller is disposed in front of or behind the roller via a frame, the raised flange can be made linear.
