Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a mounting structure for a rainwater collecting basin which is mounted on the upper wall of a concrete building such as a building to perform roof drainage.

(Prior art) A rainwater collecting masu is constructed on the roof of a building or on the upper part of the wall of a building to drain water from the balcony, and the rainwater flowing down from the roof is guided to a vertical gutter to be drained.

Conventionally, the work of attaching this water collecting trough to the wall surface is to drive in anchor bolts for fixing the water collecting trough in advance around the drainage pipe that was projected on the upper part of the wall surface,
On the other hand, a fixing hole was opened on the back surface that abuts the wall surface of the water collecting basin, the above anchor bolt was inserted into this fixing hole, and it was fixed by tightening with a nut or the like from the inner side of the water collecting basin.

(Problem) When constructing by such a conventional method, when the wall surface of the building is tiled, etc., the position where the anchor bolt is driven is limited to the joint part of the tile, etc., so the water collection is performed in relation to the vertical gutter. In some cases, it may not be possible to install the masu in the most suitable place, and for that purpose it is necessary to make the alignment accurate. The work of inserting the anchor bolts into the holes and fixing them was time-consuming because of the heavy weight of the water collecting basin.

And since such a work site is on an unstable scaffolding on the upper part of the wall surface of the building, it will affect the safety of the work if it takes time to construct it, and the installation work of such a water collecting pit will be easy. It is something that can be done.

(Means for Solving the Problems) The mounting structure of the rainwater collecting basin according to the present invention for the above-mentioned problems is such that a mounting plate which is easy to install is fixed around the drain port in advance, and the mounting plate is attached to the mounting plate. Since the engaging piece provided at the connection part extending from the rear part of the water gull is engaged and rotated to perform the installation, the installation work can be done quickly and extremely easily, and therefore the safety during work is also high. Become.

(Embodiment) The attached drawings show an embodiment of the present invention, and Fig. 1 is an exploded perspective view of a connecting portion such as a water collecting tank 1 and a mounting plate.
The figure is a perspective view during the construction of the water collecting basin 1 on the wall surface.

The water collecting basin 1 is made by forming a metal plate such as a copper plate or a stainless steel plate into a substantially cylindrical shape by pressing, etc., and a falling water cylinder 12 for connecting with a vertical gutter 5 etc. is reduced in a stepped shape in the lower part. It has been extended.

Further, a tubular connecting portion 11 into which the drainage pipe 4 is inserted from the wall surface is formed to project from the rear portion on the wall surface side, and an engaging piece 13 projecting outward is formed at an end portion of the connecting portion 11 on the wall side. Two places are formed facing each other.

On the other hand, the mounting plate 2 is installed on the outer wall surface of the drain pipe 4 protruding from the wall surface, and the standing portion 23 standing upright to the front is provided on the outer peripheral edge.
A ring-shaped mounting plate 2 is provided with an engaging plate 22 projecting in one direction for collecting water at the inner peripheral edge thereof, and two engaging grooves 21 are cut at appropriate positions at appropriate positions of the engaging plate 22. The mounting plate 2 is formed in a cutout shape, and an upright portion 23 which also functions as a reinforcement is formed on the outer peripheral edge of the mounting plate 2 so as to stand upright to the front. It can be fixed by tapping into.

The substantially annular cap 3 is inserted into the connecting portion 11 in advance, but the engaging piece 13 that engages with the engaging groove 21 of the mounting plate 2 of the water collecting basin 1 is inserted through the notch 32. is there.

The cap 3 is to be fitted over the engagement portion between the connection portion 11 and the mounting plate 2 after the connection is completed, that is, the collar portion 31 provided on the outer peripheral edge of the cap 3.
Is externally fitted to the standing portion 23 of the mounting plate 2 to improve the appearance after construction and prevent rainwater and the like from entering the engaging portion.

That is, as shown in the perspective view of FIG. 2, the mounting plate 2 is brought into contact with the wall surface around the drain pipe 4 and fixed with anchor bolts or screws, and the mounting plate 2 fixed in this way collects water 1. Is engaged to perform construction.

When constructing the water collecting basin 1, the engaging piece 13 formed at the end of the connecting portion 11 is inserted into the engaging groove 21 of the mounting plate 2 while tilting the water collecting basin 1 slightly to the side, and then If the water collecting basin 1 tilted to the back is rotated and returned to the fixed position, the engaging piece 13 will become the engaging plate 22.
To complete the installation.

Finally, the above-mentioned cap 3 is externally fitted and attached to the portion thus connected, but in order to prevent the cap 3 from coming off when the cap 3 is attached, the standing portion 23 and the flange portion 31
It may be possible to provide an engaging portion or the like to each of the above and to fix them more reliably.

Fig. 3 shows a side cross-sectional view of the connection part when the connection work is completed. The water collecting basin 1 is securely attached to the wall surface via the mounting plate 2, and the rainwater flowing in from the drain pipe 4 is surely attached. The water can be drained to the inside of the basin 1.

The angle of rotation when installing this water collecting basin 1 is about 30 ° in this embodiment, but this angle can be set appropriately, and water will be collected after the installation of the water collecting basin 1 is completed. A vertical gutter 5 or the like is installed in the lower part of 1, and a cap 3 is attached to the connecting portion of the water collecting basin 1 as shown in the perspective view of FIG. 4, so that the appearance after the installation is also good.

(Effect of the invention) As described above, the mounting structure of the rainwater collecting basin according to the present invention has a mounting plate around the drain pipe, which is easy to construct,
Since the engaging end of the water collecting basin is engaged with and pivotally connected to this mounting plate, the work method is easy, and the work safety is high and the work can be performed very quickly.

In addition, the external appearance of the water collection will be improved by attaching the cap to the mounting plate after connecting and the rainwater etc. can be prevented from invading the connection part and protected, and it can withstand long-term use.
