DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transporting a roofing material such as a folded plate, and more particularly to a roofing material transporting apparatus which is suitable for easily transporting a long roof material, for example, bent into a mountain shape.

[Prior art]

In recent years, roofs of buildings such as factories, buildings, and gymnasiums are sometimes roofed using roof plates made of folded plates.
For example, the roof shingle is formed by bending a galvanized iron sheet into an inverted chevron cross section, further bending one end in the width direction into, for example, a U-shape, and fitting the other end of the shingle outside one end of the roof shingle. For example, it is formed by bending in an inverted U shape.

[0003] When constructing a roof, for example, H
On the upper surface of the beam made of shaped steel, a tight frame formed in the shape of a rectangular wave is welded and fixed, and the roof plate formed in the inverted mountain shape is arranged in a valley portion of this tight frame, for example, one of the roof plates Is fixed to the ridge portion of the tight frame by means of a suspension and a tension bolt, and the other end of the shingle is fitted to one fixed end of the shingle adjacent in the width direction. Then, they wind and join, and repeat these operations to complete the roof.

[0004] In some cases, the roof plate made of the folded plate is directly fixed to a tight frame by a set bolt depending on specifications.

[0005]

Incidentally, the roof plate made of folded plates is made of, for example, zinc-iron plate and has a thickness of 1.0 mm, a unit weight of 14.91 kg / m ² , and a width dimension 518 of a maximum width portion.
mm and a length of 5,000 mm weigh 40 kg or more.

Conventionally, such roofing materials are transported on site by workers. For this reason, not only a great deal of labor is required, but also a large number of workers are required. Further, there is a problem involving danger, and a problem that the working efficiency is not improved.

[0007] In view of the above, the present invention can mechanically, safely and efficiently transport and deliver long folded shingles, and can be easily installed. An object of the present invention is to provide a roofing material transporting device such as a folded plate which can be used, is easily removed after use, and is convenient for storing each member.

Another object of the present invention is to reduce the material and weight of one of the abutments by using a beam as a roof structural material, and to transport the shingle to a position closer to the installation site. It is an object of the present invention to provide a roofing material conveying device that can be used.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, a plurality of abutments are provided, which are portable and are detachably mounted between the pair of abutments.

According to a fourth aspect of the present invention, the abutment includes one portable abutment installed on a roof and the other abutment detachably attached to a beam as a roof structural material. Or at least a pair of abutments detachably attached to a beam as a roof structural material.

Further, the invention of claim 5 is characterized in that the suspension device is any one of a chain block, a winch, a lever block, and a hoist.

[0014]

According to the present invention, a plurality of abutments, a rail, a traveling body, and a suspension device are provided. Therefore, in use, an abutment is arranged between a place or a manufacturing place of a folded shingle and a delivery position of the shingle. Next, a rail is erected between the abutments arranged as described above, a traveling body is mounted on the rail so that the traveling body can travel, and a suspension device is attached to the traveling body to assemble the traveling body.

This makes it possible to easily assemble each member and set it in a usable state.

Then, the hanging device is pulled down at the place where the shingle is placed or at the manufacturing place, the shingle made of folded plate is supported on the hanging device, the shingle is lifted by the hanging device, and then delivered along the rail by the traveling body. It is transported to a location and handed over to roof construction workers. After handing over the shingle, the running body and the suspension device are returned to the yard or the manufacturing place of the shingle again.

By repeatedly performing the above operation,
Long and folded shingles can be transported mechanically and safely and efficiently.

After the roof work is completed, the suspension is removed from the running body, the running body is removed from the rail, and then the rail is removed from the abutment, in the reverse order of the assembling sequence.

Thus, each member can be easily disassembled and removed, and each disassembled member can be compactly collected and stored easily.

Further, in the present invention, the abutment is provided on one of the portable abutments installed on the roof and the other abutment detachably attached to a beam made of a shape steel or a steel pipe as a roof structural material. It consists of a stand. Therefore, in use, one abutment is placed and installed on the roof material storage side on the roof, and the other abutment is attached to the beam. Then
As described above, a rail is erected between both abutments, a traveling body is mounted on the rail, a suspension device is attached to the traveling body, and the rail is assembled in a usable state.

As described above, in the present invention, one abutment is mounted on the roof, and the other abutment is mounted on the beam, which is a structural member of the roof. It can be transported to a position closer to the site and sent out.

Further, in the present invention, the abutment is constituted by at least a pair of abutments detachably attached to a beam made of a shaped steel or a steel pipe as a roof structural material. Therefore,
A pair of abutments are attached to a beam, a rail is erected between both abutments, a traveling body is mounted on the rail, and a suspension device is attached to the traveling body, thereby enabling use. Thus, in the present invention, it becomes possible to transport the shingle on the roof.

Furthermore, in the present invention, any one of a chain block, a winch, a lever block, and a hoist is used for the suspension device, and since many of these are commercially available, In addition, since it can be used by selecting from commercially available products in accordance with the specifications of the entire roofing material transporting apparatus, it is possible to accurately put it to practical use.

Further, in the present invention, since the height of the abutment is adjustable, the entire roofing material transporting device is arbitrarily adjusted according to the height of the roof construction site, and the roofing sheet is transported more appropriately. And can be handed over to workers at the roof construction site.
