Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rainwater collecting pit that collects and drains rainwater that has fallen on the roof of a building or the like.

(Prior art) Conventionally, the drainage of a building, such as rainwater that has fallen on the roof of a building, is collected in a roof drain installed in the corner of the roof, and this is drained downward through a water collection pit attached to the wall of the building. It was something to do.

That is, the rainwater guided to the outside of the wall surface of the building by the horizontal pipe through the roof drain is guided to the inside of the water collecting pit by the elbow and is drained.

A falling pipe is hung vertically at the bottom of the water collecting basin, and a downpipe is connected to the lower part to form a buried pipe or the like.

Conventionally, a cubic dice shape that is easy to make is widely known as the shape of the water collecting basin, but if it is such a shape, the bottom plate will be flat, so the bottom plate part will be dusty. It was easy to accumulate.

There was also a problem that rainwater stayed and was not drained sufficiently.

For this purpose, a funnel-shaped water collecting tool may be attached inside as a separate item, but the attachment structure and the fixing place may be a problem in attaching such a separate water collecting instrument.

(Problem) As described above, rainwater that has fallen on the roof of a building is drained to a water collecting pit through drains and the like.

At this time, if the bottom plate of the water collecting basin has a flat shape, dust or rainwater is likely to stay in the corners and the bottom plate may be corroded if it is used for a long period of time.

Moreover, if the rainwater is drained inside the collecting water and directly falls onto the bottom plate portion, the bottom plate may be damaged by the impact.

For this reason, the water collecting tool may be attached inside, but if it is not firmly fixed at this time, it may come off due to the force of rainwater, and it may be attached to a place where water flows such as a hole for fixing. If it is constructed by constricting it, it may cause water leakage.

(Means for Solving Problems) In order to solve the above-mentioned problems, the water collecting basin according to the present invention has a bottom plate having a double structure, and has a funnel-shaped water collecting tool for reliably draining rainwater. Is located at the bottom of the water collecting basin, and the position where the water collecting tool is fixed to the water collecting basin is also fixed at the upper part of the rear part so that it does not become the surface of the rainwater flowing.

(Embodiment) The drawings show an embodiment of the present invention. Fig. 1 shows a water collecting basin 1 and a funnel-shaped water collecting tool 2 which are partially cut away, and this water collecting basin 1 is a building or the like. Will be installed on the upper wall of the building.

The water collecting basin 1 is formed by bending a copper plate, a stainless steel plate, or the like by a press or the like, and a falling water cylinder 13 is provided in the lower part.

In FIG. 1, a drainage pipe 3 is installed on the upper part of the wall surface of the building so as to drain rainwater that has fallen on the rooftop. The elbow is connected as described above, and a metal pipe, a PVC pipe, or the like is used for the drainage pipe 3.

Anchor bolts 31 are driven into and fixed to the upper wall surface of the drainage pipe 3 at predetermined positions.
The connection tool 32 is inserted through and fixed to 31 and the water collecting basin 1 is fixed by the screw attached to this connection tool 32 for construction.

The water collecting basin 1 has a substantially rectangular tube shape, and an insertion hole 12 for inserting the drainage pipe 3 is formed in a back plate 11 which is constructed in contact with a wall surface, and a vertical gutter 4 is removed from a bottom portion 14 at a lower portion. A water drop cylinder 13 for fitting and connecting is extended in two stages.

A funnel-shaped water collecting tool 2 arranged inside the water collecting basin 1 has a reduced diameter insertion tube 23 extending downward, and the insertion tube 23 is inserted into the falling water tube 13 for rain water. Is drained into a vertical gutter.

The upper part of the water collecting tool 2 is widened so as to easily receive rainwater, and has a substantially funnel shape as a whole.

In addition, in order to fix the water collecting basin 1 at the upper end on the back side,
A connection piece 21 having two connection holes 22 horizontally provided is extended.

Then, the connecting piece 21 is brought into contact with the back plate 11 of the water collecting body 1 and fixed by screws or the like (FIG. 2).

At this time, as shown in the side sectional view of FIG. 3, if the drainage pipe 3 is positioned above the water collecting tool 2 and the insertion pipe 23 is inserted into the falling water pipe 13, rainwater can be surely drained.

At this time, the rainwater flows down the inner peripheral surface of the water collecting tool 2, but is fixed to the drain plate 11 at the upper end avoiding this flowing water portion.

Therefore, there is no risk of water leakage from the connection hole,
The position of the upper part of the water tool 2 is stable, and the rainwater from the water distribution pipe 3 can be reliably drained in the vertical direction without shifting.

Fig. 4 is a perspective view of the above construction, but the installation screw of the water collector is also located on the upper part of the back surface, so the appearance after construction is also good and rainwater can be drained reliably. It is a thing.

(Effect of the device) As described in detail above, the water collecting basin according to the present invention has the water collecting device arranged as a separate component inside, and as a method of fixing the water collecting device, avoid the running surface where rainwater flows down. Since the back plate is fixed to the back plate by the connecting piece at the upper end, there is no problem of water leakage from the screw holes.

Further, by fixing the upper part of the water collecting tool, the water collecting tool is stably installed, and there is no fear that the position will be displaced due to the impact of rainwater.

Further, since the water collecting tool 2 is directly fixed to the back plate 11 of the water collecting basin 1, no gap is formed between the water collecting tool 2 and the back plate, so that rainwater can be surely flowed down the downpipe.
