Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a water collector used for drainage of buildings and the like.

(Prior Art) In a drainage system that discharges rainwater from the roof of a building, a water collector is fixed to an outer wall near the roof in alignment with the discharge pipe connected to the roof drain on the roof.

In this drainage system, the discharge pipe connected to the roof drain penetrates the outer wall and projects horizontally, and a notch is provided in the back of the water collector to guide the discharge pipe into the water collector. To create this notch on the back, a special tool such as a hole saw or jigsaw was required. Therefore, the applicant proposed a water collector that is easy to provide with a notch on the back and is described in Japanese Utility Model Application Publication No. 145028/1983.

(Problems to be Solved by the Invention) However, although the water collector described in the above-mentioned publication is devised for the work of opening the notch on the back, it is difficult to fix the water collector to the outer wall of the building. Not considered.

Water collectors are usually made by drilling a hole near the top edge, inserting a fixing device, and screwing it into the building's exterior wall, but water collectors used for building drainage have considerable weight and size. Working at heights with poor footing can be quite difficult and dangerous.

(Means for Solving the Problem) The water collector of the present invention solves the above-mentioned problems, and includes an expanding step portion projecting outward at the upper edge of at least one side of the water collector body. is provided, and a bulging part is formed on one side of the water collector body continuously from the expansion step at a position that does not reach the bottom of the water collector main body, and a bulge is formed in the vicinity of the end of the side surface of the expansion step. A fixture insertion portion is provided at the bottom of the expansion step, and a fixture head insertion portion that is continuous with the fixture insertion portion is provided on the bottom surface of the expansion step.

(Function) In the water collector of the present invention, it is possible to easily open a notch for inserting a discharge pipe along the bulging portion with a common saw, etc. The fixture insertion part and the fixture head insertion part allow the water collector to be fixed by hooking the water collector from above onto the fixture screwed into the outer wall of the building in advance. In addition, even after cutting the bulge to form a notch, the expansion step remains and the water collector is fixed with a distance from the building's outer wall, so even if drainage overflows from the notch, Avoid contaminating the product by transmitting it.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 6 are one embodiment of the present invention,
It is formed by injection molding of hard vinyl chloride resin or the like. In Fig. 1, reference numeral 1 denotes a water collector, with a drain pipe 2 protruding from the bottom center of the main body, and expanding steps 3 protruding outward on all four sides at the upper edge. .

A bulging portion 4 protruding outward is provided on the side surface corresponding to the back side of the main body of the water collector 1 so as to form a stepped portion 5. The bulging portion 4 is continuous with the expansion step portion 3 and is formed upward from a position that does not reach the bottom of the main body of the water collector 1.

The expansion step portions 3 on both sides of the bulging portion 4 are provided with fixing device insertion portions 6 on the side surfaces thereof from the lower end, and the bottom surface of the expansion step portion 4 is continuous with the fixation device insertion portions 6. A wide fixture head insertion portion 7 is provided. Therefore, as shown in FIGS. 6 and 7, a bolt-shaped fixture 1
1, the water collector 1 can be hooked onto the water collector 1 from above.

At the construction site, the water collector 1 is repeatedly pulled as shown in Fig. 2, and a cutting tool such as an ordinary saw 10 is cut into the step 5.
Place it on the blade and cut downward. At this time, when the saw 10 comes into contact with the expansion step 3, it can be known that the vertical cutting has been completed.

Next, as shown in FIG. 3, the saw 10 is applied from the side to cut the upper end of the bulge 4, and the bulge 4 is separated as shown in FIG. At this time, if a cut groove 9 is provided at the boundary between the bulging part 4 and the expanded step part 3 as shown in another example in Fig. 4, the work shown in Fig. 3 can be done by hand or with a simple cutter. It is also possible to execute By separating the bulging portion 4 and leaving the expansion step portion 3, the strength decreases near the upper edge of the water collector 1 is reduced.

The fixed installation location of the water collector 1 is a discharge pipe 12 communicating with a roof drain (not shown) as shown in FIG.
is installed protruding from the outer wall of the building. An anchor 14 is placed on the outer wall in accordance with the position of the discharge pipe 12, and a bolt-shaped fixture 11 is screwed in to fix it. Then, while inserting the discharge pipe 12 into the opening 8 made by cutting off the bulging part 4, drop the water collector 1 from above and insert the fixture head into the fixture head insertion part 7, and insert the fixture head into the fixture head insertion part 7. The neck is inserted into the fixture insertion part 6, and the water collector 1 is hooked onto the fixtures 11, 11 and fixed. After this, install a hard gutter 1 to the drain pipe 2 of the water collector 1.
Connect 3. A separate net body may be installed in the expansion stage portion 3 of the water collector 1.

After the water collector 1 is fixed, the expansion step 3 comes into contact with the outer wall of the building, so a gap is created between it and the main body of the water collector 1, and drainage temporarily overflows into the main body of the water collector 1. Even if the water overflows, it flows down the back side of the water collector 1 and does not leak, stain, corrode, or rust the outer wall of the building. Even if it gets dirty, it is on the back of the water collector 1 or the back of the gutter 13, so it is not noticeable and there is no problem of corrosion.

(Effects of the Invention) As explained above, the present invention is provided with an outwardly projecting expansion step on the upper edge of at least one side of the water collector body, and a continuous expansion step with the expansion step. A bulge is formed on one side of the water collector body at a position that does not reach the bottom of the water collector body, so a special tool such as a hole saw or jigsaw is required to cut the bulge. It is possible to create an opening for inserting the discharge pipe using a normal cutting tool without having to do so, and using the expansion step as a guide, it is possible to avoid leaving the upper edge of the water collector and causing a decrease in strength. . In addition, a fixture insertion part is provided near the end of the side surface of the expansion step, and a fixture head insertion part that is continuous with the fixture insertion part is provided on the bottom surface of the expansion step. The water collector can be fixed by hooking it from above to the fixed fixture, making it easier to work in high places with poor footing. Furthermore, by providing the expansion step, a gap is created between the water collector and the outer wall of the building, so that overflow water from the water collector does not stain the outer wall of the building.
