Further, on the lower surface of the lid portion 1b, as the third attachment portion 6, from the lower end of the side wall portion 1a to the lower surface of the lid portion 1b, a total of four notched portions 6a are provided at intervals of 90 degrees with respect to the central axis, and the bottom surface is formed. As shown in FIG. 3, at a position slightly eccentric from the center of the lid 1b from one end of the cutout 6a (the end of the cutout 6a on the right side when the cutout 6a is arranged at the upper end in bottom view). A linear rib portion is provided toward the side. Since the ribs extend in all the four cutouts 6a, the ribs intersect at a corner near the center.
Further, on the outer side surface of the side wall portion 1a of the combined jig 1, at an intermediate portion between the axial lateral groove portion 3b and the cutout portion 6a, an annular groove 8a is provided along the entire periphery along the peripheral edge of the side wall portion 1a, The annular groove 8a is provided with a ring-shaped O-ring packing O made of an elastic material such as rubber for watertightly and airtightly closing between the side wall portion 1a of the combined jig 1 and the inner surface of the drainage port 9a.

The above-described waterproof pan B for a washing machine and the drain trap using the drain port member 9 are constructed as follows by using the combined jig 1.
First, the packing P is attached to the peripheral edge of the mounting hole B1 of the waterproof pan B for a washing machine so that the peripheral edge of the mounting hole B1 is sandwiched by the open portions having a U-shaped cross section.
Next, the tubular portion of the drainage port member 9 is inserted into the mounting hole B1, and the lower surface of the flange portion 9c is brought into contact with the peripheral upper surface of the mounting hole B1 via the packing P.
Next, the trap body 10 having an underfloor pipe connected to the discharge port 10b is placed below the waterproof pan B for the washing machine, and the female screw portion 10a of the trap body 10 is screwed into the male screw portion 9d of the drainage member 9. ..
At the time of this screwing, since the trap body 10 is connected to the underfloor pipe and is fixed in an arbitrary direction according to the underfloor pipe, by rotating the drain member 9 instead of the trap body 10, The mouth member 9 and the trap body 10 are screwed together.
Here, the drain port member 9 and the trap body 10 are screwed together by utilizing the function of the tightening jig as described below among the functions of the combined jig 1.
After the drainage member 9 and the trap body 10 are screwed together to some extent by hand, the drainage member 9 is set with the side having the first mounting portion 4 and the second mounting portion 5 of the combined jig 1 facing upward. It is arranged above the drainage port 9a, and the projection 9b in the drainage port 9a is aligned with the vertical groove portion 2 in plan view, and then inserted into the drainage port 9a.
By doing so, as shown in FIG. 5, in the combined jig 1, the convex portion 9b is positioned relative to the drain port member 9 in the direction of the vertical groove portion 2, that is, in the direction along the axis of the drain port member 9. It is movable, but is fixed to the drain member 9 in the circumferential direction of the drain member 9.
Further, the handle member T is attached to the combined jig 1. To attach the handle member T to the combined jig 1, the following method 1. Method 2. There are two methods. When the combined jig 1 is used as the tightening jig, the handle member T is connected to rotate the combined jig 1 in both clockwise and counterclockwise directions.
Method 1. By connecting, as the handle member T, a wrench (not shown) having an end matching the hexagonal shape of the first mount portion 4 to the first mount portion 4, the handle member T is attached to the combined jig 1. Can be connected. The wrench as the handle member T is configured so that it can be rotated in both clockwise and counterclockwise directions without causing idle rotation.
Method 2. As the handle member T, a linear rod-shaped member such as a driver is arranged on the second mounting portion 5 along the second mounting portion 5 as shown in FIG. At this time, the tip of a rod-shaped member such as a screwdriver abuts and is fixed in the recess of the center side end of the second mounting portion 5.
Further, since the rib portions are provided on both the left and right sides of the rod-shaped member, the rod-shaped member is locked by using the depression at the center side end as the fulcrum portion 7, and the rod-shaped member is grasped in either the left or right direction. Even if it is moved, the rod-shaped member can be brought into contact with the rib portion in the moving direction and the combined jig 1 can be rotated in that direction as it is.
Method 1. Or method 2. When any one of the above methods is used to grip the handle member T formed of a wrench or a rod-shaped member and rotate the combined use jig 1 in the direction in which the drainage port member 9 is screwed, the combined use drainage member 9 is used. 1, the drainage member 9 is fixed in the circumferential direction of the shaft, so that the drainage member 9 is also rotated together with the combined jig 1, and the drainage member 9 is rotated and screwed to a required tightening strength. It becomes possible.
When the screwing progresses sufficiently, the lower surface of the flange portion 9c and the upper end portion of the trap body 10 sandwich the peripheral edge of the mounting hole B1 via the packing P, and the drain port member 9 and the trap body 10 are used for the washing machine. It is connected and fixed to the mounting hole B1 of the waterproof pan B.
After the attachment of the drain port member 9 and the trap body 10 is completed, the tightening jig is pulled upward and removed from the drain port 9a. As described above, the combined jig 1 is configured such that the convex portion 9b is movable with respect to the drainage port member 9 in the direction of the vertical groove portion 2, that is, in the direction along the axis of the drainage port member 9, so that there is no problem. The combined jig 1 can be pulled out from the drain port 9a.
Next, the Owan member 12 is locked to the inner flange portion 9e of the drain port member 9, and the tubular member 11 is fitted in a watertight manner to complete the construction of the drain trap on the waterproof pan B for the washing machine. ..

Next, a method of closing the drainage port 9a using the combined jig 1 in order to perform a water leakage test using a liquid, which is the method described in paragraph 0005, will be described. Here, the drainage port 9a of the drainage port member 9 is blocked by utilizing the function of the blocking jig among the functions of the combined jig 1 as follows.
The dual purpose jig 1 is turned upside down from the state of paragraph 0019, and as shown in FIG. 7, the side having the third mounting portion 6 is placed above and above the drain port 9a of the drain member 9. Next, when the convex portion 9b in the drainage port 9a is aligned with the guide groove 3a of the jig 1 for planar view and the lateral groove portion 3b is inserted into the drainage port 9a to the height position of the convex portion 9b, the O-ring packing O is formed. It is arranged between the outer side surface of the combined jig 1 and the inner side surface of the drainage port 9a, and water-tightly connects both members. That is, in this embodiment, the annular groove 8a and the O-ring packing O function as the sealing portion 8. Further, by rotating the closing jig, as shown in FIG. 8, the convex portion 9b is guided onto the lateral groove portion 3b, and the combined jig 1 is moved in the vertical direction which is the axial direction of the drainage member 9. It is fixed in an immovable state and is watertightly connected to the drainage port 9a by the sealing portion 8.
The watertight connection by the hermetically sealing portion 8 is performed by disposing the hermetically sealing portion 8 between the inner side surface of the drainage port 9a and the outer side surface of the dual purpose jig 1, and the dual purpose jig 1 to the drainage port member 9. It is not necessary to press with a strong force. Therefore, when the combined jig 1 is used as a closing jig, all the operations to be added to the combined jig 1 can be performed manually.
Thereafter, the water leakage test can be conducted by the method described in paragraph 0005.

  In the use of the combined use jig 1, the combined use jig 1 is used as a tightening jig for tightening the drainage member 9, and after the construction is completed, the combined use jig 1 is used as it is as a closing jig, and the drainage outlet is used. It is preferable to block 9a. The reason is that even if the water leakage test is not performed immediately after the construction is completed and the water leakage test is performed at a later date, by keeping the combined jig 1 attached to the drainage port 9a as a closing jig, it becomes unnecessary to manage the members. Therefore, it is not necessary to add the combined jig 1 to the drainage port 9a and rotate it again when performing the test. As will be described later, the drain trap cannot prevent backflow of odors and pests from the sewage side when there is no sealed water inside the drain trap, but the drain trap remains as-built and unused. Since no drainage flows through the pipe, naturally there is no sealing water inside the drainage trap, and it is not possible to prevent odor and backflow of pests from the sewage side. However, by closing the drain port 9a with the combined jig 1, it is possible to prevent odor and backflow of harmful insects from the sewage side regardless of the presence or absence of sealing water in the drain trap.

When the combined use jig 1 is pulled out from the drainage port 9a after the water leakage test is completed, the combined use jig 1 is rotated to move the convex portion 9b to the position of the guide groove 3a, and then the combined use jig 1 is used. The combined jig 1 can be pulled out from the drainage port 9a by moving the above.
Here, when the combined jig 1 was attached to the drainage port 9a as a closing jig, the construction could be performed manually as described above. However, when the combined use jig 1 used as the closing jig is removed from the drainage outlet 9a and the combined use jig 1 is attached to the drainage outlet 9a for a long period of time, for example, an adhered matter or a sand dust may be present in the gap. As a result, the combined pressure jig 1 is pressed from below due to the occurrence of water pressure / atmospheric pressure in the drain trap, and the lateral groove 3b and the convex portion 9b are strongly pressed. As a result, the combined use jig 1 is manually rotated. Sometimes it can be difficult.
In such a case, by attaching the bar-shaped handle member T to the third attachment portion 6, the combined jig 1 can be easily rotated.
The third mounting portion 6 will be described below with reference to FIGS. 9 and 10. In order to facilitate the description, in the following description of this paragraph, the description will be made based on the third attachment portion 6 shown by A in FIG. The upper, lower, left, and right sides with respect to the third mounting portion 6 of FIG.
As the handle member T, a linear rod-shaped member such as a driver is arranged so as to pass through the notch 6a of the third mounting portion 6. At this time, the tip of the rod-shaped portion of the handle member T is made to abut the corner portion of the end portion on the center side of the third attachment portion 6.
When trying to rotate the handle member T in the clockwise direction in FIG. 3, the handle member T contacts the upper side wall surface (or rib portion) as shown in the drawing, but as shown in FIG. Cannot be fixed to the corner because the tip comes off from the corner.
On the other hand, when it is attempted to rotate the handle member T in the counterclockwise direction in FIG. 3, the handle member T comes into contact with the side wall surface on the lower side in the drawing, and the tip portion of the handle member T comes into contact with the corners. Since it is fixed, the combined jig 1 can be rotated in the leftward direction under stress.
That is, in the third mounting portion 6 of the present embodiment, only when the handle member T is rotated counterclockwise in FIG. 3, the corner portion serves as the fulcrum portion 7, and the side wall portion 1a on the left side of the cutout portion 6a is the rib portion. , The combined jig 1 can be rotated by operating the handle member T, and cannot be rotated because there is no structure that functions as the fulcrum portion 7 in the clockwise direction.
Here, when the combined jig 1 is used as the closing jig, the work for attaching the combined jig 1 to the drainage port 9a can be achieved by manually rotating the closing jig clockwise. It is not necessary to dispose the handle member T on the third mounting portion 6 to perform the work. On the other hand, in the work for removing the combined jig 1 from the drainage port 9a, it may be difficult to manually rotate the closing jig, and in that case, the handle member T needs to be attached. That is, in this embodiment, when the handle member T is connected to the dual-purpose jig 1 as a closing jig, it is only necessary to rotate the dual-purpose jig 1 counterclockwise, and the dual-purpose jig 1 rotates the dual-purpose jig 1 clockwise. It can be said that what is caused is rotation in an improper direction.
