Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the roof of a simple building such as a bus stop, garage, or storeroom.

[Conventional technology and its problems]

Many of these buildings are simple, consisting of just a roof spanning pillars and beams, but the roof itself is also often formed simply by arranging panel members made of metal or synthetic resin. These panel members may be thin if the entire building is relatively small, and their ends can be overlapped and joined together.
When a building grows to a certain size, the area of the roof becomes larger, and the panel members themselves are required to be stronger, so thicker members are used.

When such relatively thick panel members are laid side by side, the ends cannot be overlapped, so joints are formed, and it is necessary to seal these joints to prevent rain from seeping in. In general, caulking material and back-up material inside the joint are used to seal joints, not just on roofs, but this alone often provides an incomplete watertight seal. exposed to
Deterioration progresses from here.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a roof for a simple building which can ensure complete waterproofing by forming a joint sealing structure in multiple layers and can also prevent deterioration of caulking material.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a structure in which when a roof is formed by arranging panel members in parallel on a supporting member such as a purlin installed between beams, a projecting piece having an upward projecting piece at the tip is provided at the side end of the panel member. A piece and a protrusion above it are respectively formed to protrude laterally, a rain gutter made of channel material is spanned between the opposing protrusions, and a caulking material is formed between the opposing protrusions and the lower part thereof. The gist of this method is to close the caulking material with a back-up material, and to place a flat joint board on top of the caulking material.

[Effect]

According to the present invention, at the joints formed between panel members, the first caulking material and the second backup material perform a sealing function, and there is also a rain gutter as a tertiary prevention, so that no water is collected there. Rainwater will never pass through these joints to the back of the roof. Further, the upper surface of the caulking material is covered with a joint plate and is not exposed upward.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a longitudinal sectional front view of the main parts of an embodiment of the roof of a simple building according to the present invention, and Fig. 2 is a perspective view showing an example of a building using the roof of the present invention. 2 indicates a support column, 2 indicates a beam spanned between the support columns, and 3 indicates a support member such as a purlin installed between the beams to support a roof member. Then, the roof is formed by laying a large number of panel members 4 side by side on this support member 3 in the horizontal direction. In the figure, 5 indicates a rain gutter that is attached along the beam at the end of the panel member 4.

The panel member 4 includes an aluminum plate 6,
An aluminum sandwich panel with intermediate insulation material 7 sandwiched at 6' is used. The panel member 4
A protruding piece 9 whose tip is an upward protruding strip 9a is provided to protrude from the lower end of the side edge plate 8 in the horizontal and lateral direction.

Further, from the middle part of this side edge plate 8, a protruding piece 10, which is a protruding strip 10a whose tip is directed upward, is provided horizontally and laterally, and a hollow protruding part 11 having a substantially rectangular cross section is provided horizontally above the protruding piece 10. did. Note that the protrusion 11
The upper part of the side wall is a vertical surface, and the lower part forms an inward triangular groove 11a.

In the figure, reference numeral 12 denotes pressing pieces provided at appropriate intervals in the longitudinal direction of the panel member 4, and engagement grooves 1 are formed on the lower surface of one side of the pressing pieces.
3, and the lower surface of the other side is an upwardly tapered surface 14, and a leg piece 1 is formed inside the tapered surface 14.
2a was formed. A bolt hole 15 is provided in the center of this pressing piece 12 .

The pillar 1, the beam 2, the support member 3, the rain gutter 5 and the pressing piece 12 can all be made of extruded aluminum alloy, and the side edge plate 8 of the panel member 4
Extruded aluminum alloy sections are also used.

In the figure, 16 is a rain gutter made of C-shaped channel material, 1
Reference numeral 7 indicates flat joint plates, which are also made of aluminum alloy extruded shapes or plates.

In this way, a large number of panel members 4 are arranged on the support member 3 installed on the beam 2, and at this time, the protrusions 9, 10 and the hollow protrusion 11 are opposed to each other with some gap between them. Ru.

The panel member 4 is fixed by screwing the pressing piece 12, which is stretched between the protruding pieces 9, onto the support member 3 with the screw 18. The strip 9a is pressed by the piece 12
The pressing piece 12 is screwed by engaging with the engagement groove 13 of the other panel member 4, and then the protruding piece 9 of the other panel member 4 is formed between the lower tapered surface 14 on the other side of the pressing piece 12 and the supporting member 3. It is stopped by being fitted into the hollow space provided.

One end of the rain gutter 16 is fixed in advance to the side edge plate 8 of one of the panel members 4 with double-sided adhesive tape 19, and the rain gutter 16 is placed across between the protrusions 10a at the tips of the protrusions 10, 10. The end of this rain gutter 16 communicates with the rain gutter 5.

Furthermore, a rubber bead 20 which also serves as a back-up material is placed between the opposing hollow protrusions 11, 11 so as to be inserted into the triangular groove 11a at one end, and a caulking material 21 made of butyl rubber or the like is interposed thereon to seal the joint. I do.

Furthermore, the joint plate 1 is placed above the caulking material 21.
7, a joint plate 17 is placed over the protrusions 11, 11.
At this time, the joint plate 17 is fixed by the adhesive force of the caulking material 21.

[Effect of idea]

As described above, when the roof of the simple building of the present invention is formed by arranging panel members side by side on a support member such as a main house installed between beams, the inside of the joint formed between the panel members is Not only is it double-sealed with caulking material as the primary seal and backup material as the secondary seal, but the rain gutter below it acts as a tertiary waterproofing, creating a triple waterproof structure. A complete water stop effect can be obtained. Furthermore, the upper surface of the caulking material is covered with a joint board to prevent it from being exposed to the outside, which prevents deterioration of the caulking material and also helps maintain the aesthetic appearance.
