Description

[Detailed description of the invention] The present invention improves the drainage of water from the waterproof pan by forming an inclined piece with a gutter-like part at the lower end of the waterproof pan to which the collector is attached in a solar heat collector, thereby improving its durability. This invention relates to an improved waterproof pan for mounting a solar collector.

A waterproof pan for installing a solar heat collector inside is installed on the sloping field board using waterproof paper such as asphalt roofing, and roof tiles are laid around the waterproof pan and close to the waterproof pan to prevent the solar heat collector from being damaged. A so-called built-in solar heat collector is often used to reduce the upward protrusion and improve the aesthetic appearance. By projecting the inclined piece above the tile at the lower end of the waterproof pan, rainwater in the waterproof pan is discharged from the inclined piece to the upper part of the tile.

However, with conventional waterproof pans, the slope of the water on the sloping piece is extremely gentle compared to the slope of the roof, resulting in poor drainage, resulting in water pooling especially near the bends of the sloping piece, which promotes corrosion of the waterproof pan. It was also a cause of heavy rain.

The present invention aims to provide a waterproof pan that can solve these problems, and an embodiment thereof will be described below with reference to the drawings.

In the figure, waterproof pan 1 for installing the solar collector of the present invention.
The roof tiles 2 are directly attached to the roof board 4 of the roof 3 on which the tiles 2 are laid, via a waterproof sheet 5 such as asphalt roofing, and the tiles 2 are placed close to the waterproof pan 1. be done.

The waterproof pan 1 has a flat plate shape made of, for example, a decorative steel plate, into which the solar heat collector 6 can be assembled using mounting pieces 7, and on both sides of the pan 1 there are provided external walls at a height exceeding the peaks a of the roof tiles 2. A side wall 10 is formed with an overhanging piece 9 extending toward the side, and a rear wall 12 is provided with an upper overhanging piece 11 that can be inserted into the lower end of the roof tile 2 when it is laid.

Further, on the lower edge of the waterproof pan 1, there is a slanted piece 13 projecting upward beyond the mountain part a of the tile 2 installed near the lower edge.
will be established over the goldmine.

Note that the inclined piece 13 is inclined so as to have a water slope when the waterproof pan 1 is installed on the roof board 4, and
The inclined piece 13 has a gutter-like part 15.15 formed on its lower edge, which can fit into the valley of the tiles 2 arranged side by side.

The gutter-shaped portion 15 has a gentler bending angle from the bottom plate 16 of the waterproof pan 1 than the inclined piece 13 so that it can fit into the valley of the tile 2. 1 is installed on the roof board 4, it has a water gradient that is larger than that of the inclined piece 13, and the gutter-shaped portion 15 is installed on the sloped piece 1.
3, and is formed with the bent portion C as the base end.

The waterproof pan 1 is divided along its inclination direction, including an inclined piece 13 and a rear wall 12, and its divided edges 16, 1
7 are provided with rising pieces 19, 20, respectively, and above the rising pieces 19, 20 are formed bent pieces 21, 22 which are both bent in the same direction and are horizontal.

Furthermore, compared to the bent piece 21 located on the bending direction side of the bent pieces 21 and 22, the width of the other bent piece 22 is relatively large, for example, about t of the width of the tile 2. The bent piece 22 is set at a higher bending position than the bent piece 21, so that the bent piece 21.
22, there is a watertight material 2 made of an elastic material between the opposing surfaces.
3 can be interposed.

However, in the waterproof pan 1 of the present invention, the waterproof pan 1 is mounted on the waterproof sheet 5 such as asphalt roofing placed on the roof board 4, and the solar heat collector 6 is housed inside the waterproof sheet 5 using the mounting piece 7. The roof tiles 2 are laid on the side walls 10 and 12 in the vicinity of the waterproof pan 1 as described above.

In addition, in the figure, the tile 2 attached to the right side of the side wall 10 is formed in a semi-cylindrical shape with only a peak a, and the inclined piece 13 at the lower edge extends outward beyond the peak a of the tile 2. At the same time, the gutter-like portions 15 can be fitted into the valleys of the tiles 2, respectively.

In addition, when installing the waterproof pan 1, the contact positions of the bent pieces 21 and 22 are changed according to the width of the tile 2 so that the gutter-shaped portion 15 can be located in the valley of the tile 2. In addition to being able to adjust the length, the watertight material 23 is interposed between the bent pieces 21 and 22 as described above, and the watertight material 23 is glued between the bent pieces 21 and 22, so that the waterproof pan 1 is integrated. be joined to.

As described above, the waterproof pan of the present invention has a gutter-like part on the sloped piece at the lower end that fits into the valley of the tile and has a larger water gradient than the sloped piece. Water can flow out smoothly from the gutter-like part, preventing water from pooling, preventing corrosion of the waterproof pan, and improving its durability. Therefore, it is possible to prevent water from accumulating even at the bent portion C of the inclined piece.

Furthermore, when a large amount of rainwater flows into the waterproof pan, the water flows down over the sloped piece, preventing rainwater from overflowing to the sides and improving waterproof performance.

It should be noted that the gutter-like waterproof pan may be provided not only at both ends but also at the center, and the cross section of the gutter-like portion may be semi-cylindrical or U-shaped.

In addition, by dividing the waterproof pan along the inclination direction as in this embodiment, the waterproof pan can be formed using narrow plate materials.
In addition to being able to reduce costs, the joints are made between the bent pieces at the top of the rising piece, compared to the so-called seam joints used in conventional waterproof pan manufacturing. This will prevent water from entering the attic and prevent water from leaking into the attic.
