Description

[Detailed Description of the Invention] The present invention relates to a tool for bending the ends of a folded metal roof to form a side door integrated with the roofing material.

Folded roofs, in which multiple peaks with trapezoidal cross-sections are bent parallel to each other on a metal plate, have come to be frequently used in buildings. A mento door is installed between the mountain areas where water is cut off.

By the way, conventional mendo is made up of a metal plate that is separate from the roofing material and has a shape that closes the cross-section of the space formed by the flat part of the folded roof and the mountain sides on both sides. To attach a door to a folded roof, a thief was used and the door was fixed to the roofing material using rivets or the like.

However, in such a conventional mento structure, a mento door member separate from the roofing material is required, and attaching this member to the roofing material requires troublesome work, and the shield deteriorates over time. There was a problem with aging and gaps forming, causing rainwater to leak.

Such a problem can be solved by bending the end of the roofing material and making it stand up, and forming a side door with this upright part.

The present invention thus provides a tool for integrally molding a side door from roofing material.

Hereinafter, the details of the present invention will be explained with reference to examples.

First, to explain the door formed by processing roofing material using the tool of the present invention, as shown in FIG. At the same time, the end portions of the mountain side surfaces 21.21 that are continuous with the raised portion 4a are folded back to form triangular raised portions 4b, 4b. Part 4
A, 4b, and 4b constitute a side door 4 having approximately the same height as the mountain portion 2.

The tool of the present invention for bending the surface door 4 is comprised of a pair of clamping pieces 5, 6 and an operating rod 9, as shown in FIGS. 2 and 3.

The clamping piece 5 is made of a rectangular steel plate with a length that is almost the same as the width of the roofing flat part 3, and a series of flanges 51 and 52 that stand up at right angles are formed on the front edge and both side edges. The proximal edge of .52 is formed into an arc shape.

Further, one end of an operating rod 9 is fixedly welded to the center of the flange side surface of the clamping piece 5.

The clamping piece 6 is also made of a steel plate, and consists of a clamping part 61 having the same length as the clamping piece 5 but slightly wider than that, and guide pieces 62, 62 bent at both ends of the clamping part 61.

The angle formed by the clamping part 61 and the guide pieces 62, 62 is almost the same as the angle formed by the rising part 4a and the rising part 4b of the intended surface door 4, and is slightly larger than the right angle.

The clamping pieces 5, 6 are fixed by bolting with a spacer 7 interposed between the flat back side of the clamping piece 5 and the clamping part 61 of the clamping piece 6. The front edges of the clamping pieces 5 are parallel to each other, and the front edges of the clamping pieces 5 are located ahead of the clamping pieces 6 by the thickness of the roofing material 1.

The guide pieces 62, 62 of the clamping piece 6 protrude outward and in a direction opposite to the clamping piece 5.

A spacer 7 is provided between the two clamping pieces 5 and 6 so that the roofing material 1
A gap 8 is formed that is slightly wider than the thickness of
The distance to this point is approximately the same as the height of the upright portion 4a, that is, the height of the mountain portion 2.

In order to process and form the target door 4 using the tool configured as described above, insert the clamping piece 5 of the tool onto the flat part 3 of the roofing material 1 along the flat part 3 as shown in FIG. The flat part 3 is placed in the gap 8 between the clamping piece 5 and the clamping piece 6, and its edge is a spacer 7.
Insert until it touches the

Next, as shown in FIG. 5, when the operating rod 9 is rotated 90 degrees in the upright direction, the flat portion 3 is bent while being held between the tip edges of the holding pieces 5 and 6.

At the same time, the mountain side 21. ．． The 2 m ends are guided by the guide pieces 62, 62 of the tool and are deformed and folded back to form triangular raised parts 4b, 4b (FIG. 1).

In this case, since the base edge of the flange of the clamping piece 5 is formed into an arc shape, the bending process can be performed without damaging the roofing material 1.

As shown in FIG. 1, by bending the roofing material 1 with the tool described above, the flat part 3 of the roofing material 1 is made to stand up at right angles to form an upright part 4a and a convex side surface 21 which is continuous with the upright part 4a.
．． The surface door 4 consisting of the standing portions 4b, 4b having the raised portions 21 can be formed very easily.

Since the mento door 4 formed by this tool is integrally formed with the roofing material 1, there is no risk of rainwater leaking even after long-term use, and the mento door is a separate member from the roofing material 1. This eliminates the need for folding roofs and thieves, which greatly contributes to reducing the cost of folded roofs and improving manufacturing workability.
