Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a drain trap that is attached to a drainage body that is embedded in a floor surface of a bathroom or the like and has a lower portion connected to a sewer pipe.

(B) Conventional Technology FIG. 3 is a perspective view showing a drainage body (drainage unit) to which a conventional drainage trap is attached.

As shown in the cross-sectional view of FIG. 4, this drain trap includes a tubular trap body 11 having upper and lower openings and a trap body 11
It is composed of a bowl-shaped middle cylinder 12 fitted and disposed in 11, and a trumpet cylinder 13 having a lower opening fitted into the middle cylinder 12 and an upper part thereof locked to the inner circumference of the upper part of the cylindrical main body 11. This drain trap is designed such that the trap main body is fitted to the bathroom floor surface (tile surface) 5 and fixed to a drainage base (recessed hole) provided in advance and the bottom opening 41 of the drainage body 4 having an upper opening and a bottom. The upper part of 11 is locked and attached.

Sewage on the bathroom floor surface 5 flows into the drainage body 4 from the cover plate 42 of the drainage body 4, and flows into the middle cylinder 12 via the eyelet 14 and the trumpet cylinder 13 of the drain trap (trap body 11). To do. Then, the sewage overflowing in the middle cylinder 12 is drained to the sewer pipe 6 through the connection cylinder part 15 protruding from the space between the middle cylinder 12 and the trap body 11 to the lower part of the trap body.

By the way, the joint gap A between the bathroom floor surface (tile surface) 5 and the drainage body 4 is usually filled with a filling material (caulking material such as white cement). However, there is a possibility that sewage may leak into the base mortar layer B from the joint gap A due to the secular change of the filling material. Therefore, in recent years, a waterproof mass 7 as shown in FIG. 3 has been used. This waterproof mass 7 is formed by casting and has a plurality of through holes at appropriate places in the upper part.
A tubular body 72 having upper and lower openings forming 71, and a guard plate-like water leakage prevention plate 73 integrally projecting from the tubular body 72 immediately below the through hole 71.
It consists of In use, as shown in the sectional view of FIG. 4, the lower connecting portion 74 of the waterproof mass 7 is connected to the sewer pipe 6, and the drain trap (trap body 11) in the tubular body 72 is connected.
Is fitted. As a result, the bathroom floor surface (tile surface) 5
Water leaking into the ground mortar layer B through the joint gap A between the drainage body 4 and the drainage body 4 is received by the collar plate-like water leakage prevention plate 73,
Further, the water is leaked from the water leakage prevention plate 73 through the through hole 71 to the sewer pipe 6 through the fitting gap between the waterproof mass 7 and the trap body 11.

(C) Problems to be solved by the invention The above-mentioned conventional water leakage prevention measures use a waterproof mass in addition to the drain trap, and the water leakage received by the water leakage prevention plate of the waterproof mass is applied between the waterproof mass and the drain trap. It is a method of draining to the sewer pipe via. Therefore, this method requires a waterproof mass in addition to the drain trap, and it is unacceptable that the number of parts will be large and the cost will be high.This waterproof mass is a cast molded product and is very heavy because of its large shape It is inconvenient and has disadvantages such as difficulty in drainage maintenance work.

It is an object of the present invention to solve the above problems, to provide a drain trap that is inexpensive and can easily implement measures to prevent water leakage, and that construction work is simple.

(D) Means and Actions for Solving the Problem In order to achieve this object, the drain trap of the present invention has the following configuration.

The drain trap is a tubular trap that is attached to the bottom surface of the drainage body that is embedded in the floor of the bathroom, etc. so that it can be detachably projected downward and is connected to the sewer pipe. It is characterized in that a through hole for letting water leaking from the floor into the inside is opened at an appropriate position of the main body, and a water leak receiving means that integrally projects outward from the trap main body is provided around the corresponding hole. .

In the drain trap having such a configuration, the trap body itself has a water leakage receiving means and a through hole corresponding to the water leakage receiving means. The water leakage receiving means is, for example, a dish-shaped disc that is curved upward and has a diameter larger than the diameter of the drainage body. In other words, the joint gap position between the bathroom floor and the drainage body is
The size is set so as to be located in the plane of the lower water leak receiving means (disc-shaped disc). Leakage water (dirty water) entering the ground mortar layer through the joint gap between the bathroom floor surface and the drainage body is received by the water leakage receiving means and guided to the through hole,
It flows into the trap body from the through hole and is drained to the sewer pipe. Therefore, unlike the conventional case, a waterproof mass other than the drain trap is not required, and the drainage facility can be completed at a low cost with a small number of parts. Also, since the water leakage receiving means is integrally formed with the trap body (made of synthetic resin), it is lightweight and can be manufactured at low cost.
Transportation is convenient and drainage work can be performed easily.

(E) Embodiment FIG. 1 is a perspective view showing a concrete embodiment of the drain trap according to the present invention.

As shown in the sectional view of FIG. 2, the drain trap 1 is a known drain trap (drain trap of the conventional example shown in FIG. 4).
The configuration is almost the same as. That is, a tubular trap body 11 having upper and lower openings formed of a synthetic resin material or the like, a bowl-shaped middle cylinder 12 fitted and arranged in the trap body 11, and a lower portion fitted into the bowl-shaped middle cylinder 12, The upper part of the trap body (11) is a trumpet tube (13) having an upper opening and a lower part that engages with the inner circumference of the upper part of the trap body (11). The drain trap 1 is fitted to a bathroom floor surface (tile surface) 5 in a drainage base (a hollow hole) provided in advance and fixed to a bottom opening 41 of a square tubular drainage body 4 having an upper opening and a bottom. On the other hand, the upper part of the trap body 11 is detachably locked and attached.

Sewage on the bathroom floor surface 5 flows into the drainage body 4 from the cover plate 42 of the drainage body 4, and the plate 14 and the wrapper tube of the drainage trap 1 are discharged.
It flows into the middle cylinder 12 via 13. Then, the sewage overflowing in the middle cylinder 12 is passed from the fitting between the middle cylinder 12 and the trap body 11 to the sewer pipe (branch rising pipe from the sewer pipe) 6 through the connecting cylinder part 15 projecting to the lower part of the trap body 11. Be drained.

The feature of this invention resides in that the trap body 11 is provided with a water leak receiving means 2 and a through hole 3 for inflowing water.

As shown in FIG. 1, a plurality of through holes 3 are formed in the peripheral surface of the trap body 11 at a substantially central depth. This through hole 3
The opening position of is set to be slightly above the height position of the upper opening surface of the middle cylinder 12. This allows
The sewage flowing into the middle cylinder 12 through the wrapper cylinder 13 and overflowing from the middle cylinder 13 is prevented from flowing backward from the through hole 3.
In addition, the through hole 3 is inclined upward from the inner surface side of the trap body 11 to the outer surface side thereof to facilitate leakage of water.

The water leak receiving means 2 is formed in a disk-shaped (dish-shaped) collar plate that integrally projects from the outer peripheral surface of the trap body 11 in correspondence with the through hole 3 (immediately below the through hole 3). . The water leakage receiving collar plate 2 is set in a funnel shape that is inclined upward toward the outside. In other words, the base of the water leakage receiving collar plate 2 is provided around the outer periphery of the trap body 1 so as to project obliquely upward from immediately below the through hole 3. This inclination angle substantially corresponds to the inclination angle of the through hole 3. Further, the collar plate 2 for receiving water leakage is set to have a larger diameter than the diameter of the drainage body 4. That is, the position of the joint gap (filling material portion) A between the drainage body 4 and the tile floor surface 5 is set to be within the surface of the water leakage receiving collar plate 2 located below. Further, a step portion 21 projecting upward is provided around the outer peripheral portion of the water leakage receiving collar plate 2 to prevent the once leaked water from leaking outward.

In the drain trap having such a configuration, the bathroom floor surface 5
Leakage water (dirty water) entering the base mortar layer B through the joint gap A between the drainage body 4 and the drainage body 4 is received by the water leakage receiving means 2 and guided to the through hole 3. The leaked water flows into the trap body 11 through the through hole 3 and is drained to the sewer pipe 6 through the connecting tubular portion 15. Therefore, unlike the conventional case, a waterproof mass other than the drain trap 1 is not required, and the drainage facility can be completed inexpensively with a small number of parts. Further, the water leakage receiving means 2 is
Since it is formed integrally with the trap body (made of synthetic resin) 11, it is lightweight and can be manufactured at low cost, is convenient to carry, and can easily perform drainage work.

(F) Effect of the Invention In this invention, as described above, the outer peripheral edge of the drainage body and the drainage are attached to the outer peripheral surface of the tubular trap body fitted and attached to the bottom opening (drainage port) of the drainage body. A water leakage receiving collar plate that is set to a size where the joint filling gap with the tile floor surface is located in the plane is projected continuously, and multiple through holes are provided at appropriate places in the tubular trap body. Since it is decided that the water leakage received by the water leakage receiving collar plate is made to flow into the tubular trap body, the water leakage receiving collar plate is integrally provided in the tubular trap body, and is integrally provided in the so-called drain trap itself. Therefore, the water leak receiving means can be attached at the same time by the same simple work as when attaching a normal drain trap to the drain body. Therefore, unlike the conventional case, an extra member for mounting the water leakage receiving stage other than the drain trap is unnecessary, and a drainage device that is inexpensive and easy to install can be provided.

Further, the water leakage receiving collar plate provided in the drain trap (cylindrical trap body) itself is set to a size such that all joint filling gaps at the outer peripheral edge of the drainage body are located in the plane. Therefore, not only leakage from the joint gap corresponding to the outer edge of the bottom opening provided on the one end side of the drainage body, but also from all joint filling gaps at the boundary between the drainage body and the drainage floor tile surface. It has an excellent effect of achieving the object of the invention, such as being capable of completely catching water leakage and completely eliminating the risk of water leakage over a wide range.
