Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a waterproof pan for mounting a solar water heater.

The background to this invention is that in order to install a solar water heater on a tiled roof where solar heat radiation is difficult to block, wires have traditionally been strung from the left, right, front, and back of the protective frame of the solar water heater. However, especially in strong winds, the solar water heater could be blown away or the wire could break, so it was not installed safely and securely.

This invention was made to solve such problems.

The present invention will be explained below based on the drawings of the embodiments.

FIG. 1 is a perspective view of an embodiment of the present invention.

In the figure, 1 stands for the entire circumference extending from front to back, left and right, 2a, 2
A front rise 2a rising from the bottom part 3 of the plate body 1 is constituted by an inclined piece 4 inclined forward and upward.

When the slope of the slope piece 4 is determined based on the bottom surface part 3, the slope angle θ of the slope piece 4 with respect to the bottom surface part 3 varies depending on the slope angle of the roof to be installed. The inclination angle θ needs to satisfy the relationship 180°−θ≦or.

This inclined piece 4 is bent and connected to the front end portions of the upright portions 2b and 2C that rise on both the left and right sides.

Furthermore, at the tip of this inclined piece 4, there are 2 rising up on both sides.
b. Last month 5, which is separate from 2C, has been extended.

This last month 5 is bent with respect to the inclined piece 4 and forms a surface parallel to the bottom part 3.

Note that the point where the last month 5 is bent with respect to the inclined piece 4 is not a limiting condition, and it may be formed on the same surface as the inclined piece 4.

The rear riser 2d is formed with a step 6 that is one step lower than the rear ends of the left and right risers 2b and 2C.

And rises 2b, 2 on both the left and right sides for the purpose of water stopping effect.
A drainer 8 is formed by extending an L-shaped flange 7 outward from C and the rear rising edge 2d.

Raised convex portions 9 are formed on the bottom surface portion 3 on the front, rear, left and right sides.

The convex portions 9 may be scattered or irregular.

Note that this waterproof pan A is suitably made of a material such as FRP or a resin-coated metal plate such as a PVC steel plate.

The waterproof pan A having the above-mentioned structure is constructed as shown in FIGS. 2, 3, and 4, and the solar water heater is installed thereon.

Figures 2, 3, and 4 are cross-sectional views showing the state of use;
This is applied to a solar water heater installed on a roof covered with tiles. Figure 2 is a cross-sectional view taken in the slope direction of the roof, Figure 3 is a cross-sectional view taken in the horizontal direction of the roof, and Figure 4 is a cross-sectional view taken in the horizontal direction of the roof. is a perspective view.

First, let's talk about the roof base.

As for the roof base, a sheath board 11 is placed on the rafters 10, and a waterproof sheet 12 made of a synthetic resin sheet or asphalt-impregnated paper is placed on top of this.

A waterproof pan A is placed on this waterproof sheet 12.

In this case, the inclined piece 4 of the waterproof pan A is on the eave side and the rear rising part 2
d is placed on the ridge side, and the adjacent rafter 10
．． Angle 13 is installed above and below 10.

The convex part 9 provided on the bottom part 3 of the waterproof pan A and the L above it
A bolt 16 passing through the horizontal piece 17 of the mold fitting 21 is inserted into the hole 15 passing through the shedding board 11 and waterproof sheet 12 and the hole 14 of the angle 13, and the bolt 16 is inserted through the shedding board 11 and the angle 13 on both sides of the bolt 16. The L-shaped fittings 21 are fixed to the convex portions 9 so that the rafters 10 are sandwiched, and the waterproof pan A is attached to the roofing board 11. It is fixed and attached to a base material such as rafters 10.

Furthermore, the vertical piece 18 of this L-shaped fitting 21 and the solar water heater B
The solar water heater B is fixed with bolts 20 that pass through the protective frame 19 of the solar water heater B.

Next, the fitting of the inclined piece 4 side of the waterproof pan A will be explained.

A support plate 22b is installed between the square timbers 22 fixed horizontally on the roof board 11 and the roof board 11 above the square timbers 22a, and a hardening waterproofing material 24 such as plaster or mortar is applied to the eaves side of the square timbers 22. This support base 23 is packed with
A waterproof sheet 12 is layered on top, and the inclined piece 4 of the waterproof pan A is placed on top of this to support it.

Furthermore, waterproof pan A's last month's number 5 is on top of tile C.

Next, to explain how the rear rising edge 2d of the waterproof pan A fits, the tile C is covered with snow on the rising edge 2d, and the tip of the tile C is held in a state slightly recessed into the bottom part 3, and between the tile C and the flange 7. The formed gap is filled with a hardening waterproof material 24 such as plaster or mortar to prevent rainwater from entering.

Note that 25 is a support material that supports the flange 7.

Next, the rises 2b and 2d on both the left and right sides of the waterproof pan A will be explained.

The tile C is covered with arc-shaped raw tiles C0 stacked on the flange 7, and a hardening waterproofing material 24 is similarly filled between the flange 7 and the raw tiles 01 to prevent rainwater from entering.

Finally, to explain how the solar water heater B subsides, one end of the plurality of U-shaped brackets 26 is attached downward to the protective frame 19 of the solar water heater B with bolts 20, and the L
The casing 27 bent into the shape is fixed with screws to form the protective frame 1.
It is constructed by surrounding the entire circumference of 9.

Note that 28 is a pipe housed within the casing 27.

As is clear from the above installation structure, rainwater that has entered the waterproof pan A can be drained from the risers 2b and 2C provided on both left and right sides and at the rear.
, 2d, the water stops and flows downward along the slope of the roof.

Since the front riser is composed of a layered slope piece 4 connected to the risers 2b and 2C on both sides, rainwater from the bottom part 3 is drained without stopping the water on the slope piece 4, and the roof tiles C It flows past the last month 5 on the top and reaches the top of the tile C.

Due to this 5° angle last month, rainwater flows smoothly down to the eaves without entering the gaps between the roof tiles.

Furthermore, since this last month 5 is separated from the rising edges 2b and 2C on both sides, it is possible to bend it on site so that it meets the tiles.

Also, since the rear rise 2d has a step 6 that is one step lower than the rises 2b and 2C on both sides, the flanges 7 on both sides
Tile stacked on top and tile C stacked on the rear flange
This is because it is possible to roof the □ level to the same level.

Furthermore, since the raised convex portion 9 is used as a mounting part for a mounting fitting that can be mounted with a bolt, rainwater will not enter through the bolt hole.

As described above, in this invention, the front rise rising from the bottom of a light-colored dish body having a series of rises around the entire circumference is composed of an inclined piece that slopes forward and upward, and is further separated from the rises on both sides. This waterproof pan for installing a solar water heater is characterized in that the last month is extended to the tip of the inclined piece, and the pan is securely fixed by being placed on the roof base instead of on the tiles.

The waterproof pan for installing solar water heaters, which is new as a product, has a water-stopping function when it rises, and the sloped piece at the front allows rainwater to drain from the bottom along the slope of the roof. Rainwater can be reliably flushed upward in the last month.
