TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drainage device. More specifically, the present invention relates to a drainage tool that is easy to attach and that is well drained.
[0002]
[Prior art]
2. Description of the Related Art In recent years, floors and walls of verandas and the like have been coated with fiber-reinforced plastic (hereinafter, referred to as FRP) for waterproofing verandas and balconies of detached houses and wooden houses. However, when a drainage device called a drain is installed in a drainage port provided on a floor or a wall coated with FRP, a drainage device made of a vinyl chloride resin or a casting generally used in the past, and a floor coated with FRP is used. The adhesion to the surface does not work well, and the drainage tool is easily peeled, causing water leakage.
[0003]
Therefore, recently, a drainage device made of FRP, which has good compatibility with an FRP coating such as a floor, has been used.
[0004]
As shown in FIG. 7, the drainage tool 30 made of FRP has a flange 31 extending around a drainage port E opened on a floor F of a veranda and a cylindrical part 32 inserted into the drainage port E formed of FRP. It was made integrally. A pipe made of a vinyl chloride resin or the like is adhered to the tube portion 32, and the tube portion 32 and a pipe made of the vinyl chloride resin or the like are integrally formed.
[0005]
When the drainage device 30 is installed on the floor F, the floor device F is coated with FRP at least once before and after the installation, so that the drainage device 30 and the coating on the floor F are integrated by the same type of FRP, so that there is a fear of water leakage. Disappears. After the FRP coating on the floor F is hardened, a finished top coat is applied to the floor F, and a strainer is attached to the drain port E, whereby the attaching operation is completed.
[0006]
As another example of a conventional FRP drainage tool, a horizontal drainage tool 33 shown in FIG. 8 includes a vertical flange portion 34 extending around a drainage port E opened in a wall W of a veranda and a floor F. The extending horizontal brim portion 35 and the cylindrical portion 36 inserted into the drain port E are integrally formed by FRP. Then, as in the case of the drainage tool 30 described above, the cylindrical portion 36 is also adhered to a pipe made of vinyl chloride resin or the like, and the cylindrical portion 36 and the pipe made of vinyl chloride resin or the like are integrally formed.
[0007]
[Problems to be solved by the invention]
However, when the conventional FRP drainage device 30 shown in FIG. 7 is installed in the drainage port E of the veranda floor F, the FRP flange 31 is relatively thick (about 1.5 to 2.5 mm in thickness). Therefore, it is necessary to process the floor F so that the water can easily pass over the collar portion 31 and flow to the drain port E in order to improve drainage. That is, after opening the drain port E in the floor F, it is necessary to form a step S around the drain port E for embedding the flange 31 of the drainage tool 30 in the floor F using a grinder or the like. Yes, the installation work was complicated.
[0008]
Also, in the case of the horizontal drainage tool 33 shown in FIG. 8, since the vertical flange portion 34 and the horizontal flange portion 35 made of FRP are relatively thick, as described above, the water is drained by the vertical flange to improve drainage. A step S for embedding the vertical flange 34 and the horizontal flange 35 in the wall W and the floor F, respectively, is formed using a grinder or the like so that the vertical flange 34 and the horizontal flange 35 are respectively embedded in the wall W and the floor F so as to easily pass through the portion 34 and the horizontal flange 35 and flow to the drain port E. And the mounting operation is complicated.
[0009]
The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a drainage tool that can be easily attached and is well drained.
[0010]

[0015]
A vertical drainage device 1 shown in FIGS. 1 to 3 is a drainage device attached to a drainage port E opened on a floor F such as a veranda, and a collar 2 made of a thin metal plate extending around the drainage port E. And an FRP tubular drainage body 3 inserted into the drainage port E. In FIG. 3, T is a pipe made of a synthetic resin such as a vinyl chloride resin, which is fixed to the lower end of the drainage tool main body 3 with an adhesive or the like.
[0016]
The collar 2 has an outer diameter d ₁ (about 30 to 400 mm) larger than the diameter D ₁ of the drain port E, and is used for thin metal plates such as stainless steel, iron, copper, aluminum, lead, zinc, brass, titanium, and titanium alloy. It is formed in an annular shape by performing punching and the like. In the present embodiment, the outer shape of the collar 2 is annular, but the present invention is not limited to this, and the outer shape of the collar 2 may be rectangular or another shape. A receiving seat 4 that fits into the drainage port E is provided inside the collar 2. The receiving seat 4 includes a circumferential wall portion 4a facing the inner circumferential surface of the drain port E, and an annular seating surface portion 4b provided at a downstream edge of the circumferential wall portion 4a. In addition, as long as a certain strength and bending resistance can be obtained in addition to the metal described above, the collar 2 is a concept including a glass fiber reinforced plastic. The same applies to the following, a urethane resin, a urea resin, an acrylic resin. It can be made of resin, vinyl chloride resin, ABS, polycarbonate, polyamide such as nylon, polyolefin such as polypropylene and polyethylene, epoxy resin and the like.
[0017]
Further, the flange 2 of the present embodiment is formed with the slits 5 radially arranged at equal intervals while being inclined in a substantially spiral shape, so that after the drainage tool 1 is inserted into the drainage port E, the floors F and When the entire surface of the drainage tool 1 is coated with FRP, the FRP resin also penetrates into the inside of the slit 5 so that the collar 2 and the floor F can be more tightly bonded.
[0018]
The shape and arrangement of the through holes or slits formed in the collar 2 to allow the penetration of the FRP resin are not limited to the slits 5 shown in FIGS. Through holes or slits having a shape and arrangement can be adopted. For example, as shown in FIG. 4, the slits 6 may be periodically arranged along the circumferential direction of the brim 2 so as to represent a figure imitating a floral pattern.
[0019]
Also, as shown in FIG. 2, the distortion is corrected near the outer peripheral edge of the collar 2 (in the case of a stainless steel collar, the plate may be distorted due to its small thickness. May be corrected), or small through holes 7 may be formed at equal intervals to facilitate lining by fixing the collar to the base.
[0020]
Drainage device body 3, for example can be manufactured by heating and curing the FRP sheet to a predetermined shape, the diameter D ₁ of the discharge port E at the upstream side edge of the _(see FIG. 3) smaller than the outer diameter d ₂ ring Are protruded. The drainage tool main body 3 may be made of urethane resin, urea resin, acrylic resin, vinyl chloride resin, ABS, polycarbonate, polyamide such as nylon, polyolefin such as polypropylene or polyethylene, epoxy resin, or the like, in addition to FRP. .
[0021]
In the drainage device 1 shown in FIGS. 1 to 3, the engaging edge 7 of the drainage device main body 3 engages with the receiving seat 4 (specifically, the annular seat surface portion 4 b) of the collar 2, and thereby the drainage device made of FRP is formed. The entirety of the component body 3 can be inserted into the drain port E and disposed at a predetermined position. Therefore, as shown in FIG. 3, the drainage tool 1 attached to the drainage port E has an extremely high strength while the brim 2 made of a thin metal plate has sufficient strength to withstand use compared to a conventional FRP brim. Since it is formed to be thin, there is no need to form a step around the drain port E unlike a conventional drainage tool, and the work of attaching the drainage tool can be facilitated. Moreover, since the collar 2 made of a thin metal plate is much thinner than the flange made of FRP, water can flow smoothly on the surface of the collar 2 on the floor surface, and drainage is good.
[0022]
The thickness of the collar 2 is preferably about 0.05 to 1.0 mm in consideration of conditions such as good drainage and strength that can be used. In the present invention, since the collar 2 is made of, for example, stainless steel, the plate thickness can be significantly reduced as compared with a conventional one.
[0023]
Next, as another embodiment of the drainage tool of the present invention, a horizontal drainage tool 11 shown in FIGS. 5 to 6 is a drainage tool attached to a drainage port E opened in a wall W such as a veranda. It is composed of a collar 12 made of a thin metal plate extending around the mouth E, and a tubular drainage body 13 made of FRP inserted inside the drainage port E. In addition, the lower side of the drainage tool main body 13 is flat in order to widen a frontage of a portion where drainage flows.
[0024]
The collar 12 has an outer dimension larger than the diameter of the drain port E, and has a substantially rectangular vertical flange portion 14 extending around the drain port E opened on the veranda wall W, and a substantially rectangular horizontal flange extending to the floor F. And a unit 15. A receiving seat 16 fitted to the drain port E is provided inside the collar 2. The receiving seat 16 includes a circumferential wall portion 16a facing the inner circumferential surface of the drain port E, and a substantially C-shaped seat surface portion 16b provided on a downstream end edge of the circumferential wall portion 16a.
[0025]
The drainage tool body 13 can be manufactured by, for example, heating and hardening an FRP sheet into a predetermined shape, and has a substantially C-shaped engaging edge 18 having an outer diameter smaller than the diameter of the drainage port E at an upstream end edge. Is protruding.
[0026]
In the horizontal drainage device 11 shown in FIGS. 5 to 6, the engagement edge 18 of the drainage device body 13 engages with the receiving seat 16 (specifically, a substantially C-shaped seat surface portion 16 b) of the collar 12. The entirety of the FRP drainage body 13 can be inserted into the drainage port E and disposed at a predetermined position.
[0027]
Therefore, as shown in FIG. 6, the drainage tool 11 attached to the drainage port E has an extremely high strength while the brim 12 made of a thin metal plate has sufficient strength to withstand use compared to a conventional FRP brim. Since it is formed to be thin, there is no need to form a stepped portion on the wall and floor around the drain port E unlike the conventional drainage tool, and the work of attaching the drainage tool can be facilitated.
[0028]
In addition, since the collar 12 made of a thin metal plate is much thinner than the flange made of FRP, water can flow smoothly on the surface of the collar 12 on the wall surface and the floor surface, and drainage is good.
[0029]
Furthermore, since the plurality of through holes 17 are formed over the entire surface of the collar 12 of the present embodiment, the wall W and the floor F, and the wall W and the floor F are inserted after the drainage tool 11 is inserted into the drain outlet E. When the entire surface of the drainage tool 11 extending to both sides is coated with FRP, the FRP resin also penetrates into the inside of the slit through-hole 17, so that the gap between the collar 12 and the floor F and the gap between the collar 12 and the wall W are formed. The space can be more closely adhered.
[0030]
【The invention's effect】
The drainage tool of the present invention is formed by a metal sheet having a very thin thickness while maintaining sufficient strength to withstand use compared to a conventional FRP collar. There is no need to form a step around the mouth, and the work of attaching the drainage tool can be facilitated.
[0031]
In addition, the collar made of a thin metal plate is much thinner than the flange made of FRP, so that water can flow smoothly on the surface of the upper collar such as a floor surface, and drainage becomes very good.
