Description

  The present invention relates to a structure for mounting a drainage member such as a wash basin or a tank body, a drain pipe, a drain trap, a drainage device, and the like.

For example, a well-known attachment structure for a drain port and a drain trap is shown in FIG. The drain outlet and drain trap mounting structure is composed of a tank body, a drain outlet, a drain plug, and a drain trap that is a drain member.
The tank body is a box body, and has a drain opening described later at the bottom. In this conventional example, the tank body is used as a bath tub.
The drain port is a hole opened at the bottom of the tank body, and is an opening for draining the drainage water stored in the tank body to the outside of the tank body.
The drain plug is a cylindrical member that is attached to the drain outlet, and has a flange that protrudes outward from the upper end. Further, a male screw is screwed around the outer periphery of the cylinder.
A drainage trap as a drainage member is a member that stores a part of drainage called sealed water inside so as to prevent odors and pests from the sewage from flowing backward into the room. This drain trap has a box shape, and the drain plug is inserted into the upper surface and constitutes an insertion portion for allowing drainage to flow into the drain trap. This insertion part is a circular hole, and forms an internal thread that is screwed into the external thread of the drain plug on the inner peripheral surface thereof. In addition, the drain trap constitutes a sealing upper limit wall configured by raising the bottom surface in a wall shape and a sealing lower limit wall configured by hanging from the insertion portion in a wall shape in order to store the sealed water inside. . Sealing water is formed by the sealing water upper limit wall and the sealing water lower limit wall, and the sealing water does not cause odors and pests from the sewage to flow backward into the room. Moreover, the discharge port for draining the waste_water | drain in a waste_water | drain trap out of a waste_water | drain trap is comprised in the downstream side surface from the sealing lower limit wall of a box. In addition, a drain pipe is connected to this discharge port, and this drain pipe is finally piped to a sewer pipe. (Patent Document 1)

There are two methods for attaching the conventional drainage port and drainage member mounting method or mounting structure. First, the first construction method is described.
First, a washing place pan is installed in the bathroom, and a drain trap for the tank is connected in advance to a sewer pipe in a tank installation space disposed beside the washing place pan. And a tank body is installed in a bathroom so that the drain outlet of a tank body may be located just above the insertion part of a drain trap. An inspection opening for construction is configured in the washing area pan, and the installer enters the tank body from the inspection opening. In addition, in order to attach a drain plug to the drain outlet of the tank body, another contractor inserts the drain stopper into the drain outlet, and locks the drain plug trap to the drain outlet via the watertight member. And, the drain trap is inserted into the male threaded part of the drain plug that protrudes from the drain port on the back side (bottom) side of the tank body through the watertight member, and the drain trap is inserted by the builder on the back side of the tank body. Keep it fixed. Then, another worker rotates the drain plug from the upper side of the tank body from the upper surface side of the tank body so that the male screw of the drain plug and the female screw of the insertion portion of the drain trap are screwed together. At this time, the tank body itself is large in a box body, and tightening of the screw must be done without fixing one member in order to prevent the other member from rotating when one member is rotated, From these two points, the installer cannot tighten the screw alone. Therefore, when performing construction as in this embodiment, the installer for fixing either the drain plug or the drain trap and the installer for rotating either the drain tap or the drain trap Two people are needed.
In addition, when the drain plug and drain trap are attached and fixed to the tank body, the installer who has been submerged under the tank body comes out from the inspection port of the washing room pan. Then, the construction of the conventional drainage port and drainage trap mounting structure is completed by watertightly sealing the inspection port.

Next, a conventional method of attaching the drainage port and the drainage member or the second construction method of the attachment structure will be described.
First, a washing place pan is installed in the bathroom, and a drain trap for the tank is connected in advance to a sewer pipe in a tank installation space disposed beside the washing place pan. And a tank body is installed in a bathroom so that the drain outlet of a tank body may be located just above the insertion part of a drain trap. And a drainage plug is inserted into the drainage port of the tank body, and the drainage stopper's hook is locked to the drainage port through a watertight member, so that the builder has a rod-shaped jig whose tip is hooked from above the tank body. Is inserted into the drain plug, and the jig is hooked on the insertion part of the drain trap located just below the drain port of the tank body. Then, the installer lifts the drain trap upward through the jig, and inserts the male screw of the drain plug into the drain trap insertion portion through the watertight member. Then, the installer keeps the jig pulled up with one hand, and rotates the drain plug with the other hand. Then, the male screw of the drain plug and the female screw of the insertion part of the drain trap are screwed together. In this way, when the fastening of the drain plug and the drain trap is completed, the drain trap can be firmly attached and fixed to the drain outlet of the tank body. When this installation is completed, the installer lifts the jig from the drain plug, and the installation is completed.

In the conventional drainage port and drainage trap mounting structure, drainage flows as follows.
Drainage generated on the washroom pan is drained from the drainage port of the washroom pan to a sewer pipe through a drain trap attached to the drainage port of the washroom pan.
Moreover, the waste water in the tank body which is a tank body flows in into a drain trap through the drain plug attached to the drain outlet. Wastewater drained into the drainage trap passes through the sealed water via the sealing lower limit wall, reaches the sealing ceiling wall, and drainage overflows from the sealing ceiling wall to the outside of the drain trap through the drain trap outlet. And drained. Moreover, the waste water drained out of the drain trap is finally drained to the sewer pipe through the drain pipe. In addition, the stored drainage water at the lowest end of the sealing water lower limit wall and the uppermost end of the sealing water upper limit wall is the sealing water depth, and odors and pests from the sewage enter the indoor side by the sealing water depth. Prevents backflow.

Japanese Patent No. 3168401

The above-described Patent Document 1 drainage port and drainage member mounting method or mounting structure has the following problems.
First, if the construction method described in paragraph 0003 is adopted, the connecting means between the drain plug and the drain trap is screwed together, so if either the drain plug or drain trap is not fixed, the screw screw When they are combined, either the drain plug or the drain trap is brought together, and the screw cannot be screwed. Also, especially in tanks and waterproof pans installed in bathrooms etc., the tank bodies and waterproof pans to be installed are very large. does not spin. Therefore, two installers are required.
Moreover, in such a construction method, since an operator must sneak under the tank body, an inspection port is required for the washing place pan.
In addition, it was a very dangerous work because one builder had to dive into the dark and narrow space under the tank.
In addition, when the construction method described in paragraph 0004 is adopted, the construction can be performed by one person, but the drain plug needs to be rotated in a narrow space in the tank body or the screw screwing work with one hand closed is very difficult. It was difficult to install. In addition, leakage between the drain plug and the drain trap, especially in apartment buildings, has a great negative effect on the lower layer dwelling, and must be prevented. Therefore, the connection of the drain plug and the drain pipe by screwing must be strictly managed by torque management, and must be tightened with a torque wrench or the like. However, as described above, it is very difficult for one installer to manage the torque with a torque wrench while pulling up the jig inside the narrow tank body, which is a cause of poor construction.

From the above, the present invention solves the following problems.
1. Improved workability 2. 2. One person can perform construction. Reduction in the number of work processes

The attachment method or attachment structure of the drain outlet and the drainage member of this embodiment is used for a drainage trap for a bathtub in a bathroom.
As shown in FIGS. 1 to 4, the bathroom in which the present invention is adopted is composed of a tank body 1 and a washing place pan, and the washing place pan is placed beside the tank body 1. The washing area pan has an opening at the bottom, and a drainage device with a trap function is attached to the opening, so that wastewater generated on the washing area is drained from the opening of the washing area pan to the drainage device, and finally Drained into the sewer pipe. In addition, a remote-operated drain plug device that remotely operates and opens and closes a valve element disposed at the drain port 12 is provided.
Moreover, the attachment method or attachment structure of the drainage port and drainage member of this invention employ | adopted for this bathroom is the tank body 1, the drainage port 12, the drain plug 122, the drainage trap 2 which is the drainage member 2, and a ring. The body 4, the stopper 7, and the watertight member 32 are configured.
The tank body 1 is a box, and has a drain port 12 described later at the bottom. In the present embodiment, the tank body 1 is used as a bath tub.
The drain port 12 is a hole opened at the bottom of the tank body 1, and is an opening for draining the water stored in the tank body 1 to the outside of the tank body 1.
The drain plug 122 is a cylindrical member that is attached to the drain port 12, and has a flange that protrudes outward in the upper end. Further, a male screw is screwed around the outer periphery of the cylinder. Further, a notch 123 is formed below the drain plug 122, and a ring body 4 described later is disposed in the notch 123. The drain plug 122 is attached to the tank body 1 drainage port 12 via the drainage port 12 by a nut member, with a hook locked to the drainage port 12. And the convex line with which the stopper stopper 7 mentioned later engages is comprised in the drain plug 122 inner periphery.
The drainage trap 2 as the drainage member 2 is a member that stores a part of the drainage called sealed water inside and prevents the odor and pest from the sewage from flowing backward into the room. The drain trap 2 has a box shape, and the drain plug 122 is inserted into the upper surface of the drain trap 2, and an insertion portion 21 for allowing drainage to flow into the drain trap 2 and a downstream of the insertion portion 21. The locking part 22 is configured to have a larger diameter than the diameter of the insertion part 21.
The insertion portion 21 is a circular hole, and an internal thread is formed on the inner peripheral surface thereof to be engaged with the external thread of the drain plug 122. Moreover, the insertion part 21 is comprised smaller than the outer diameter when the stress of the ring body 4 mentioned later is not added.
The locking part 22 is a part configured to be downstream of the insertion part 21 and configured to lock and store a ring body 4 described later, which is configured to have a diameter larger than the diameter of the insertion part 21.
In addition, the drain trap 2 has a sealing upper limit wall 23 configured by raising the bottom surface in a wall shape and a sealing lower limit wall configured by hanging from the insertion portion 21 into a wall shape in order to store the sealed water inside. 24 is configured. The sealing water is formed by the sealing water upper limit wall 23 and the sealing water lower limit wall 24, and the sealing water does not cause odors and pests from the sewage to flow backward to the indoor side. Further, a discharge port 25 for draining the drainage in the drainage trap 2 to the outside of the drainage trap 2 is formed on the downstream side surface of the lower limit wall 24 for sealing water of the box. Further, a drain pipe is connected to the discharge port 25, and this drain pipe is finally piped to a sewer pipe.
The ring body 4 is a C-shaped ring as viewed from above, and is disposed in the cutout portion 123 of the drain plug 122. The material is preferably made of metal or synthetic resin. In this embodiment, synthetic resin is used. In addition, the ring body 4 includes an inclined surface 41 that is inclined obliquely upward from the lower end surface. When the drain plug 122 is inserted into the insertion portion 21, the insertion portion 21 contacts the inclined surface 41 of the ring body 4, and the diameter of the ring body 4 decreases toward the center due to the stress of the contact. Further, when the drain plug 122 reaches the locking portion 22 configured downstream of the insertion portion 21, the force in the diameter reducing direction of the ring body 4 is released and the diameter is expanded outward. Then, the ring body 4 is locked to the locking portion 22 of the drainage member 2.
The retaining stopper 7 prevents the connection between the drain port 12 and the drainage member 2 due to the diameter being reduced in the central direction due to some stress when the ring body 4 is expanded in diameter by the locking portion 22. In this embodiment, the member is a cylindrical member having an outer shape substantially the same diameter as the inner periphery of the drain plug 122. Further, in this embodiment, it is also used as the wire receiving member of the above-described remote-operated drain plug device. The wire receiving member is a bearing for disposing the release wire 6 of the remote-operated drain plug device at the center of the drain plug 122. In addition, an engaging leg for engaging with a protrusion formed on the inner periphery of the drain plug 122 is formed at the lower end of the stopper stopper 7. The stopper 7 is detachably attached to the drain plug 122.
The watertight member 32 is a member that watertightly seals between the drain plug 122 and the drainage member 2, and is made of soft rubber or the like. In addition, the watertight member 32 is configured in a Y shape in cross section, and the drain plug 122 is attached in a Y shape so as to follow the circumference of the outer periphery of the flange 13, and the inner periphery of the insertion portion 21 of the drainage member 2. The outer peripheral surface of the watertight member 32 comes into contact with the surface, and the gap between the drain plug 122 and the drainage member 2 can be tightly sealed. Moreover, since the watertight member 32 stops water in the side surface direction, the height direction of the packing can be made lower than the case where the water stopping member is arranged in the plane direction, so that it can cope with a low floor. When watertight packing is arranged in the plane direction, a certain amount of contact stress from the vertical direction is required due to the arrangement between the members, so torque management is necessary for screw screwing. Since it is possible to provide a high water-stopping property only by setting a gap between the members in the lateral direction, torque management for water-stopping of the watertight packing becomes unnecessary. Further, since the shape of the watertight packing is Y-shaped, the end of Y elastically contacts the inner periphery of the insertion portion 21 during construction, so that better watertightness can be maintained.

The attachment method or attachment structure of the drain outlet and the drainage member of this embodiment is constructed according to the following procedure.
First, the wash basin is installed in the bathroom, and the drain trap 2 for the tub 1 is connected to the sewage pipe in the installation space of the tub 1 arranged beside the wash basin. In addition, a drain plug 122 is inserted into the drain port 12 of the tank body 1 from above in advance, and a trough of the drain plug 122 is locked to the drain port 12 through the watertight member 32, and a nut is attached to the outer periphery of the drain plug 122 from the rear surface of the tank body 1. The drain plug 122 is attached and fixed to the tank body 1. Further, the ring body 4 is attached to the notch 123 of the drain plug 122.
And as shown in FIG. 1, the tank body 1 is installed beside the washing-room pan of a bathroom so that the drain outlet 12 of the tank body 1 may be located just above the insertion part 21 of the drain trap 2. FIG. And a construction worker inserts the rod-shaped jig | tool with the hook-shaped tip from the upper direction of the tank body 1 in the drain plug 122, and the inside of the drain trap 2 located directly under the drain port 12 of the tank body 1 Hook the jig. Then, when the builder lifts the drain trap 2 upward through the jig as it is, the insertion portion 21 of the drain trap 2 is smaller in diameter than the ring body 4 arranged in the drain plug 122, so as shown in FIG. The upper end of the portion 21 abuts on the inclined surface 41 of the ring body 4, and the ring body 4 is reduced in diameter toward the center direction along the inclination of the inclined surface 41. When the drain trap 2 is pulled up as it is, as shown in FIG. 3, the ring body 4 reaches the locking portion 22 downstream of the drain trap 2, and the locking portion 22 is configured to have a larger diameter than the insertion portion 21. Therefore, while passing through the insertion portion 21, the ring body 4 that has been reduced in diameter due to the stress is released in the locking portion 22 and is expanded in the outward direction. Then, since the ring body 4 is expanded in diameter by the locking portion 22, the ring body 4 is locked to the locking portion 22 of the drain trap 2, so that the drain trap 2 is locked and connected to the drain plug 122. Then, the installer takes out the jig from the drain plug 122 and installs the remotely operated drain plug device. The release wire 6 of the remote-operated drain plug device is pulled up from the drain port 12 through the drain trap 2, and the wire is connected to a stopper 7 that functions as a wire receiving member. Then, as shown in FIG. 4, the engaging leg of the stopper stopper 7 is engaged with and attached to the protrusion in the drain plug 122 as it is. In this case, since the notch 123 of the drain plug 122 is covered from the inner periphery of the drain plug 122, the ring body 4 cannot be further reduced in diameter, and the locked state of the ring body 4 can be maintained. is there. Further, since the stopper stopper 7 also functions as a bearing for the release wire 6, when the stopper stopper 7 is attached to the drain plug 122, the end of the release wire 6 can be arranged at the center of the drain plug 122, The valve body of the remote control type drain plug device is attached to the end of the release wire 6 as it is. Thus, the construction is completed.

Moreover, the attachment method or attachment structure of the drain outlet and the drainage member of the above-described embodiment has the following drainage flow.
When drainage occurs on the washing basin pan, the drainage from the washing basin is drained into the drainage device of the washing basin pan, and the drainage in the drainage device is finally drained through the drainage pipe to the sewer pipe.
When draining the drainage water stored in the tank body 1, the drainage port 12 is opened by remotely opening the valve body seated on the drainage plug 122, and the tank is opened via the drainage plug 122 and the drainage port 12. It is drained out of the body 1. The drainage drained to the outside of the tank body 1 flows into the drainage member 2 from the insertion portion 21 of the drainage member 2 through the locking portion 22, and passes through the sealing lower limit wall 24 of the drainage member 2 that is the drainage trap 2. Passing through the upper limit wall 23 of the sealing water, the water is discharged from the discharge port 25 of the drainage member 2 to the outside of the drain trap 2 and finally drained to the sewer pipe. Moreover, since the drainage member 2 is the drainage trap 2, odors and pests from the sewage do not flow back into the room.

Embodiments of the drain port and drain member mounting method and mounting structure according to the second embodiment will be described below with reference to the drawings.
This embodiment is used for a drainage trap for a bathtub in a bathroom.
As shown in FIGS. 5 to 8, the bathroom in which the present invention is adopted includes a tank body 1 and a washing place pan, and the washing place pan is placed beside the tank body 1.
