DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arabesque product for roofing an arch-shaped roof kerb and an arch bending apparatus therefor.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, an arabesque product (or keraba product) 20 is attached to a roof 1 having an arch-shaped roof 2 of a building 1 when roofing the same. However, the arabesque product 20 is a substantially arabesque product member 8 having a discarded portion 7 and a hanging portion 5 hanging therefrom, having a substantially L-shaped cross-section, having a predetermined shape and length, and being formed straight by a forming roll or the like. The member 2 formed by cutting the cut portion 5 with the scissors 22 or the like,
A large number of 4 are prepared, and a sloping part 5 and a discard part 7 are provided at the construction site.
Was fitted to the arch-shaped roof 2.

[0003]

However, in order to attach the arabesque product member 8 to the arched roof 2 in a construction-like manner at the construction site, the dimensions of the mounting location must be measured or the straight arabesque product member 8 must be installed. It takes a lot of troublesome work such as cutting with scissors 22 or making a lot of cuts 23 in the sloping section 5, and a lot of labor is required even for the work of simply attaching the arabesque product member 8 to the arched roof 2. And had In addition, such a construction causes a cut surface to be exposed on the surface of the sloping portion 5 and the like, causes scratches and the like, deteriorates the appearance, and causes rusting.

[0004] In view of the above, the present invention can easily process a straight arabesque product member into an arch shape so as to fit an arched roof, and cut it into pieces in real time by cutting it with metal cutting scissors or the like. An object of the present invention is to provide an arabesque product and an arch bending apparatus for the same that do not require troublesome work such as making a cut in a sled portion, and have no scratches or the like on the surface.

[0005]

The arabesque product according to the present invention is an arabesque product having a sloping portion made of a metal plate for a roofing material and a discarded portion for roofing an arch-shaped roof. The portion is formed in a wavy shape composed of a repetition of irregularities, and the entire bottom portion and the discarded plate portion are curved in the longitudinal direction.

In addition, the arch bending apparatus for arabesque products according to the present invention includes a pair of corrugated rolls rotated by a drive motor, a pair of tuning gears mounted coaxially with the corrugated rolls and meshing with each other, and a pair of corrugated gears. A pair of guides arranged symmetrically with respect to the plane formed by the center line between the attached rolls, and a presser roll arranged horizontally on the corrugated roll and slidingly contacting the discarded part of the arabesque product member It is characterized by comprising. The presser roll is characterized in that its pressing force can be adjusted to a greater or lesser degree, and the corrugation depth can be adjusted.

[0007]

Embodiments of the present invention will be described below. As shown in FIG. 1, the arabesque product 4 for roofing the arch 3 of the arch 2 of the arch 2 of the building 1 is curved and formed as a whole to match the curvature of the arch 3. The portion 5 is formed in a wavy shape 6 composed of a repetition of irregularities. The unevenness of the wave shape 6 may be acute or may be rounded.

As shown in FIG. 2, the arabesque product 4 is formed by bending a corrosion-resistant metal plate or the like into a substantially L-shaped section as shown in FIG.
Is further processed. In the present embodiment, FIG.
The straight arabesque product member 8 shown in FIG.
This is to bend in the direction of the sled portion 5.

FIG. 4 shows an arch bending apparatus for the arabesque product 4. The pair of guides 11, 11 sandwich the sled portion 5 of the arabesque product member 8 from both sides and are introduced between a pair of corrugated rolls 12, 12 arranged in front. Therefore, they are fixed in a symmetrical arrangement parallel to the plane formed by the center lines between the corrugated rolls 12 and 12.

A pair of corrugated rolls 12 and 12 are rotated by a drive motor (not shown) to form a waveform on the slant portion 5 of the arabesque product member 8, and are separated from each other in a gear shape in cross section. And it rotates in synchronization. The pair of tuning gears 13 and 13 are coaxial with the corrugated rolls 12 and 12 so that the rotation of the corrugated rolls 12 and 12 can be synchronized so that the teeth and the teeth or the valleys do not face each other. Are engaged. The presser roll 14 slides on the discard plate 7 and presses it upward. The presser roll 14 is rotatably disposed above or near the corrugated rolls 12, 12, and is capable of adjusting the pressing force.

An arch bending apparatus 1 configured as described above
The operation of No. 5 will be described. As shown in FIG. 5, as shown in FIG. The corrugated rolls 12, which are rotating with their teeth and valleys (concavities and convexities) appropriately fitted to each other, bite the slanting portion 5 and send it out while forming a vertical waveform.

At this time, since the arabesque product member 4 tends to float upward, it is pressed by the pressing roll 14 so that a waveform is formed at a predetermined position. Therefore, by adjusting the corrugation depth by adjusting the pressing force of the presser roll 14, it is possible to manufacture arabesque products suitable for various arched roofs having different curvatures.

Thus, the arabesque product 4 is manufactured by forming a vertical corrugated portion on the sled portion 5 of the arabesque product member 8, whereby the length of the sled portion 5 in the longitudinal direction is reduced, and A curved body with the part 5 inside is formed. This is because the sloping plate portion 7 is flat to the last, while the slanted portion 5 is compressed by the corrugated rolls 12, 12, thereby utilizing the expansion and contraction effect of the sloping plate portion 7 and the metal plate of the slanted portion 5. And a bending process.

Furthermore, the arch bending device 15 of the present invention
Since the structure is simple and compact, it can be manufactured as a vertical or horizontal machine, and it can be easily carried to the construction site. It can be processed simply, quickly and easily.

[0015]

According to the present invention described above, since the arabesque product is formed into an arch shape in advance so as to fit the arched roof, it can be laid on the arched roof as it is, and a conventional product It does not require complicated labor such as short cutting with scissors or the like, or making a cut in a slant portion, and is simple, quick and easy to improve work efficiency.

Moreover, the arch bending apparatus can easily, quickly and easily mechanically process the arabesque product member into an arch shape, so that the surface is free of scratches and the like, and the appearance is good, and furthermore, the corrugation is obtained. By adjusting the depth of the arabesque, arabesque products that fit various arched roofs can be manufactured.
