Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roof panel.

[0002]

[Prior art]

 In view of the shortage of workers and the soaring construction costs in recent years, in order to reduce the labor required at the construction site, a tarpaulin is laid in advance at the factory on the top of the base plate to construct a roof panel, and this roof panel is constructed. It may be brought into the field and joined flush with another adjacent roof panel at the joining edge.

FIG. 4 shows a conventional joint structure of such a roof panel. Conventionally, a waterproof tape 11 is attached between joint edge portions of a roof panel 10 arranged flush with each other on a rooftop. As a result, the joint portion of the roof panel 10 is waterproofed.

[0004]

[Problems to be solved by the device]

 However, if the waterproof tape 11 is simply pasted between the joint ends of the roof panel 10, if rainwater spills under the waterproof tape 11, the rainwater immediately causes a gap between the roof panels 10 and 10. There is a risk that it may enter the space and deteriorate the structural member. On the other hand, in order to avoid the above-mentioned inconvenience, it is possible to use a considerably wide waterproof tape 11 or to double-provide the waterproof tape 11 to carefully perform waterproof treatment on the joint portion, but this can be done on site. This will lead to an increase in construction labor and material costs.

In view of such circumstances, an object of the present invention is to provide a roof panel capable of enhancing the waterproof function of the panel joint by simple construction.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention takes the following technical means. That is, the invention according to claim 1 is a roof panel in which a waterproof sheet is laid in advance on the upper surface that is flush with another adjacent roof panel at the joint edge, and projects upward from the upper surface of the waterproof sheet. It is characterized in that a water-stop ridge extends on the upper surface of the joint edge portion.

Further, the invention according to claim 2 is a roof panel in which a waterproof sheet is previously laid on an upper surface which is flush with another roof panel adjacent to each other at a joint edge portion. It is characterized in that it has a water blocking portion formed by folding back the edge toward the center of the panel.

[0008]

[Action]

 The water-blocking ridges that extend to the upper surface of the joint edge project upward from the upper surface of the waterproof sheet, so that water on the waterproof sheet can be blocked from entering the gap between the roof panels. . Similarly, the water stop provided on the joint edge of the tarpaulin is formed by folding the joint edge toward the center of the panel, so that the moisture on the tarpaulin enters the gap between the roof panels. Stop doing.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. In FIG. 1A, a roof panel 1 is provided with a rectangular flat plate 2 made of wood or ceramics extruded material, and a rafter 3 is nailed to the lower surface of the widthwise end of the plate 2. It is fixed.

A water-proof sheet 4 made of asphalt roofing or the like is previously attached to the entire surface of the field board 2 of the roof panel 1 in advance at a factory or the like, and the waterproof sheet 4 having a rectangular cross section is provided on the waterproof sheet 4. 5 is attached by nailing or adhesive. The waterproof strip 5 is made of an elastic resin material such as rubber and sponge, and is joined to the roof panel 1 so as to project upward from the upper surface of the waterproof sheet 4 (in this embodiment, a widthwise edge). Part) is extended to the upper surface.

FIG. 1B shows a joint structure of the roof panel 1. That is, the roof panel 1 is installed on the roof of the roof so that it is flush with the other roof panels 1 at the joint edge after being carried in by a crane or the like to the roof of the building which is the construction site. The waterproof tape 6 is attached from above the water blocking ridges 5 and 5 of the adjacent roof panels 1 and 1. After joining the roof panels 1 and 1, roof tiles (not shown) are tiled on the base plate 2.

[0012] Therefore, even if rainwater passes between the roof tiles and reaches the upper surface of the base plate 2 and rainwater comes under the waterproof tape 6, the water-stop projection extended to the upper surface of the joint edge portion. Since the strip blocks the water from entering the gap between the roof panels 1 and 1, the waterproof function at the joint is improved. As shown in FIG. 2, the water blocking ridge 5 may have a round cross section, or may be interposed between the base plate 2 and the waterproof sheet 4.

FIG. 3 shows a second embodiment of the present invention. In this embodiment, instead of providing the water blocking projections 5, a water blocking portion 7 formed by folding back the waterproof sheet 4 is provided. That is, the water stop portion 7 is formed by folding back the widthwise end portion of the waterproof sheet 4 toward the center of the panel along the joint edge of the roof panel 1, and similar to the water stop protrusion 5. It has a function of blocking the moisture on the waterproof sheet 4 from entering the gap between the roof panels 1 and 1.

The first point is that the waterproof tape 5 is attached on the water blocking portions 7, 7 of the adjacent roof panels 1, 1 and then the roof tile (not shown) is tiled on the base plate 2. This is similar to the case of the embodiment. In each of the above-described embodiments, the roof panel 1 in which only the waterproof sheet 4 is laid in advance on the upper surface is shown, but the present invention is a roof panel in which roof tiles are further processed on the waterproof sheet 4 in the factory. It can also be adopted as 1.

[0015]

[Effect of device]

 As described above, according to the present invention, the water blocking ridges or water blocking portions provided on the joint edge of the roof panel block the moisture on the waterproof sheet from entering the gap between the roof panels. Since it is stopped, the construction of the waterproof tape can be completed easily, and the waterproof function of the panel joint can be enhanced by simple construction.
