Description

[Detailed description of the invention] The present invention has a duct lower plate that also serves as a ceiling plate, and by attaching the duct part to the lower surface of the roofing material in advance at the factory, it is possible to simplify on-site construction and shorten the construction period. This article relates to large-sized chevron roofing materials with ducts that can be provided at low cost.

Conventionally, there have been factory-produced chevron-shaped roofing materials with long spans (length: approximately 15 m to approximately 50 m) and large sizes (height: approximately 1 m to approximately 1.5 m).

If the length is 25 m or more, it is divided into two parts for convenience of transportation.

These large chevron-shaped roofing materials are transported to the site, lifted one by one onto the structure using a large crane, and then placed and fixed between the opposing structural members at the top of the structure. ,
The adjacent large chevron-shaped roofing materials are placed in parallel with the previous one and connected together with bolts, etc. to form the roof.

The air conditioning ducts for heating and cooling were attached to the underside of the roof after the roof was covered, using scaffolding in the attic.

Installation is extremely dangerous and inefficient because it requires work at a high place in the attic, and there are disadvantages such as the need for scaffolding, which increases the cost of air-conditioning-related equipment.

Furthermore, simply installing a duct with a circular cross section would be unsightly, and it would be necessary to install a ceiling plate to cover the duct.

Therefore, in the present invention, a chevron-shaped duct upper plate is fixed to the inside of a large-sized chevron-shaped roofing material, a duct lower plate is fixed between the inclined lower end of the duct upper plate, and the duct upper plate and duct lower plate are fixed. By forming air-conditioning-related ducts, upper and lower duct plates are installed at the factory on the underside of the large chevron roofing material, eliminating the need for on-site duct installation and speeding up air-conditioning-related construction. The duct lower plate can also serve as a ceiling plate, and can be provided at low cost, eliminating the above-mentioned drawbacks.

Its structure will be explained with reference to the drawings.

Reference numeral 1 denotes a large chevron roofing material with a long span, and is integrally formed with sloped edges outward and upward from both bottoms of the large chevron portion.

Reference numeral 2 denotes a plurality of reinforcing bones, which have substantially the same shape as the cross section of the large-sized chevron-shaped roofing material 1, and are fixed to the lower surface thereof at predetermined intervals in the longitudinal direction.

3 is a long duct top plate, and its large chevron roofing material 1
It has a mountain shape that is almost the same as the top of the duct, and a heat insulating material 4 such as glass wool or rock wool is pasted on the lower surface of the duct, and the lower end of the duct upper plate 3 with an inclined surface is bent so as to wrap around the heat insulating material 4. The edge 3' is integrally formed.

The top surface of this duct upper plate 3 is individually attached to the top of the strength bone 2 with bolts or the like.

Reference numeral 5 denotes a long duct lower plate, the cross section of which may be approximately U-shaped with the top open outward (see Figures 1 and 2), or may be circular U-shaped (not shown). Sometimes I do.

The upper ends of both sides of the duct lower plate 5 have deformed U-shaped wrapping edges 5.
', 5' are integrally molded, and their wrapping edges 5' are overlapped so as to wrap around the bent edges 3' at the lower end of the duct upper plate 3, and are individually attached with rivets or the like.

This surrounding edge 5' is constructed as shown in the dotted line in FIG. 2 or in the solid line in FIG. 4, and is overlapped with the bent edge 3' during installation.

A heat insulating material 6 such as glass wool or rock wool is adhered to the inner surface (upper surface side) of this duct lower plate 5.

The duct upper plate 3 and the duct lower plate 5 constitute an air conditioning-related duct section 7.

8 is an interior material such as a decorative board, and 9 is a heat insulating material such as glass wool filled between the large-sized chevron roof material 1 and the interior material 8.

Next, the effects will be explained.

In the present invention, it is possible to manufacture a large-scale chevron-shaped roofing material 1 in which a duct part 7 is provided inside the large-scale chevron-shaped roofing material 1 produced in a factory, in which a duct upper plate 3 and a duct lower plate 5 are fixed together in a factory.

Therefore, if this is transported to the site and lifted onto the structure using a crane or the like, the duct portion 7 will be removed from the large chevron roofing material 1.
The duct section 7 can be used to install air conditioning-related equipment by simply connecting the joint section.In order to install the duct after roofing, as in the past, it is necessary to install scaffolding in the attic. This work is dangerous due to the high places in the attic, but this invention eliminates these problems and
It is safer, air conditioning equipment can be installed quickly, and it can also be done at a lower cost.

Particularly, when installed at a factory, the work is easy and the duct portion 7 can be reliably installed in a smooth manner.

In addition, if the ducts are attached using various materials after the roofing has been installed, the ducts will be exposed indoors and look extremely unsightly, so conventionally a ceiling board was installed below them, but with the present invention. The duct part 7 is composed of a duct upper plate 3 and a duct lower plate 5, and both ends of the duct lower plate 5 are connected between the lower ends of the duct upper plate 3 with an inclined surface without the need for any complicated mounting fittings. It is fixed in an orderly manner, and at the same time, the duct lower plate 5
Since both ends of the duct are located approximately in the middle of both slopes of the large chevron roofing material 1, the duct lower plate 5 covers the top of the lower surface of the large chevron roofing material 1 and the upper side of both slopes. The plate 5 sufficiently serves as a ceiling plate for the large-sized chevron-shaped roofing material 1, and there is no need to provide any separate ceiling plate, making it possible to reduce the cost.

In addition, since the duct part 7 is divided into upper and lower halves, the duct upper plate 3 can be fixed from the inside, and the installation work can be simplified.
can be made stronger.

Since the duct portion 7 is provided near the top of the lower surface of the large-sized chevron-shaped roof material 1, it can be stored extremely compactly.

For this reason, it is possible to provide daylighting windows on both slopes of the large-sized chevron-shaped roofing material 1 to take in sunlight, if necessary.

In addition, a heat insulating material 4 is provided inside each of the duct upper plate 3 and the duct lower plate 5.
, 6, the heat insulation of the duct portion 7 can be improved.
