  The lock member 6 has a male screw 6m that can be screwed into the female screw 26f of the upper tube portion 26 of the tubular member 21 in the fixing cylinder 2, and is attached to the elbow member 5 from the other end side. It has become.

  Next, the construction procedure of the drain trap 1 configured as described above will be described.

  The fixing cylinder 2 is integrally connected in advance with a flange member 22 screwed to the cylindrical member 21.

  First, in accordance with the installation position of the equipment, the mounting hole Fa is larger than the outer diameter of the drain pipe P and slightly smaller than the outer diameter of the connecting portion 24 of the tubular member 21 in the fixing cylinder 2. Is formed on the floor board F. Then, one end of the drain pipe P laid under the floor is raised so as to face the mounting hole Fa of the floor board F. Next, an adhesive is applied to the inner peripheral surface of the upper end portion of the drain pipe P, and an adhesive is applied to the outer peripheral surface of the lower cylindrical portion 23 of the cylindrical member 21 in the fixing cylinder 2, and one end portion of the drain pipe P is attached. It is inserted until it contacts the connecting portion 24, and both are bonded. When the bonding between the cylindrical member 21 of the fixing cylinder 2 and the drain pipe P is completed, the fixing cylinder 2 is placed on the floor plate F, and the screws S are screwed through the screw holes 22a of the flange member 22 to thereby fix the floor plate F. Secure to. When the fixing cylinder 2 is fixed, the decorative cover 3 is attached to the fixing cylinder 2 and the outer cover of the upper cylinder portion 26 and the outer surface of the flange member 22 are covered.

  Next, the trap body 4 is inserted into the drainage pipe P while being fitted into the fixing cylinder 2, and the peripheral step 411 is supported by the support portion 25 of the cylindrical member 21 in the fixing cylinder 2. Further, the other end portion of the elbow member 5 to which the lock member 6 is attached is inserted into the inner peripheral surface of the peripheral step portion 411 of the trapezoid 41 in the trap body 4 through the fixing cylinder 2, and the protruding portion 51 is It supports on the inner peripheral side upper surface of the connection part 24 of the cylindrical member 21 in the fixing cylinder 2. After that, if the lock member 6 is screwed into the upper cylinder portion 26 of the cylindrical member 21 in the fixing cylinder 2, the elbow member 5 is sandwiched between the fixing cylinder 2 and is not detached while ensuring water tightness. Can be fixed.

  Thus, if the drain trap 1 is attached to the floor board F, the drain hose of the equipment which is not shown in figure may be inserted in the one end part of the elbow member 5, and may be fastened via the fixed band K (refer FIG. 1). . Thereby, the waste water of the equipment is guided from the elbow member 5 to the trap body 4 through the drain hose. The drainage led to the trap body 4 flows into one space having a semicircular cross section of the rod body 41 along the inclined portion 421 of the partition wall 42 and crosses the cross section of the rod body 41 through the flow passage 4a. It reaches the other semicircular space, overflows from the outlet 4b, and flows out to the drain pipe P. Under the present circumstances, the sealing water of the height which reaches the outflow port 4b from the bottom face can be ensured inside the trapezoid 41 of the trap main body 4, and the odor which rises the drain pipe P can be sealed with water.

  By the way, when confirming the construction after the drain trap 1 is attached, the lock member 6 is loosened and the elbow member 5 and the lock member 6 are detached from the fixing cylinder 2, and then the trap body 4 is pulled up and taken out. This is performed by removing the decorative cover 3 and exposing the fixing cylinder 2 to which the drain pipe P is connected on the floor board F. Here, since the cylindrical member 21 of the fixing cylinder 2 is colorless and transparent, the inner peripheral surface of the drain pipe P is visually observed from above the floor board F through the transparent lower cylinder portion 23 of the fixing cylinder 2. can do. That is, the connection state of the outer peripheral surface of the lower cylindrical portion 23 of the cylindrical member 21 and the inner peripheral surface of the drain pipe P in the fixing cylinder 2, specifically, the presence or absence of the adhesive and the application state of the adhesive It can be grasped from above F.

  Therefore, when only the lower cylinder part 23 of the cylindrical member 21 and the drain pipe P in the fixing cylinder 2 are fitted, as described above, the outer periphery of the lower cylinder part 23 of the fixing cylinder 2 It is possible to apply an adhesive to the surface and the inner peripheral surface of the drain pipe P, respectively, and bond them together. Thereby, the water leak by the poor connection of the lower cylinder part 23 and the drain pipe P of the cylinder 2 for fixation can be prevented reliably.

  Further, the drain trap 1 can be mounted on the floor, and it is not necessary to provide an inspection port for entering the under floor space, and it is not necessary to enter a narrow under floor space through the inspection port. In combination with the fact that it is not necessary to enter the space under the floor when confirming the construction, the entire operation can be performed in a short time.

  By the way, after the drain trap 1 is attached, when the floor material such as the cushion floor needs to be replaced by renovation or the like, the elbow member 5 and the lock member 6 are loosened as described above by loosening the lock member 6. Is removed from the fixing cylinder 2, and then the trap body 4 is pulled up and taken out. Further, the decorative cover 3 is released to expose the fixing cylinder 2 to which the drain pipe P is connected on the floor board F. Next, after loosening the screw S to release the fixing of the fixing cylinder 2 to the floor plate F, the screw connection of the flange member 22 to the cylindrical member 21 is loosened and removed. Thereby, the connection part 24 of the cylindrical member 21 in the fixing cylinder 2 is placed and supported on the periphery of the mounting hole Fa of the floor board F.

  Thereafter, a minimum hole through which the connecting portion 24 can be inserted is formed in the floor material, the hole is inserted into the upper cylindrical portion 26 in the fixing cylinder 2, and the inner peripheral edge thereof is in the vicinity of the outer peripheral edge of the connecting portion 24. The flooring is laid on the floor board F so as to be positioned. When the flooring is laid, contrary to the above, the flange member 22 is screwed into the connecting portion 24 of the cylindrical member 21 in the fixing cylinder 2 and integrally connected. Next, when the fixing cylinder 2 to which the flange member 22 is connected is placed on the floor board F and the screw S is driven into the floor board F through the screw holes 22a of the flange member 22, the fixing cylinder 2 is fixed to the floor board F. Can do. As a result, the flange member 22 can cover the vicinity of the inner periphery of the hole formed in the flooring. Next, after attaching the decorative cover 3 to the fixing cylinder 2, the trap body 4 is fitted and supported, the elbow member 5 is fitted and inserted into the fixing cylinder 2, and the locking member 6 is attached to the fixing cylinder 2. Just conclude.

  Thus, since the flange member 22 does not expose the hole by covering the vicinity of the inner peripheral edge of the hole formed in the flooring, it can be performed without reducing the appearance of the flooring. In addition, it is not necessary to cut or extend the drain pipe, and it is not necessary to use a new fixing cylinder, so that the work time can be greatly shortened and the flooring can be easily replaced.

  Incidentally, in the above-described embodiment, the case where the protruding portion 51 of the elbow member 5 is supported on the upper surface on the inner peripheral side of the connection portion 24 of the cylindrical member 21 in the fixing cylinder 2 is illustrated as shown in FIG. In addition, an outer flange 412 that extends outward is formed at the upper end of the trapezoid 41 in the trap body 4, and the inside of the connecting portion 24 of the tubular member 21 in the fixing cylinder 2 corresponding to the outer flange 412. A stepped portion 241 is formed on the circumferential upper surface so as to be flush with the upper surface of the outer flange 412 of the casing 41 in the trap body 4, while a flange 52 is formed on the outer circumferential surface on the other end side of the elbow member 5. You may make it do.

  As a result, the outer flange 412 of the trap body 4 is supported by the step 241 of the connecting portion 24 of the tubular member 21 in the fixing cylinder 2, and the upper surface of the outer flange 412 of the trapezoid 41 in the trap body 4 and The flange portion 52 of the elbow member 5 can be placed and supported over the inner peripheral side upper surface of the connection portion 24 of the cylindrical member 21 in the fixing cylinder 2.

  In the above-described embodiment, the trap body 4 that secures the sealed water is exemplified by the partition wall 42 provided inside the casing 41. However, as shown in FIG. Sealing water may be secured using the member 5. That is, in FIG. 4, the trap body 4 includes a body 41, a plurality of suspension pieces 43 integrally connected to the upper end portion of the body 41 at intervals in the circumferential direction, and the upper ends of the suspension pieces 43. A ring-shaped peripheral support portion 44 integrally connected to the outer peripheral surface of the portion, and this peripheral support portion 44 is supported by the support portion 25 of the cylindrical member 21 in the fixing cylinder 2. Yes.

  On the other hand, a peripheral wall portion 53 that extends to the vicinity of the bottom surface of the body 41 of the trap body 4 is suspended from the inner peripheral portion on the other end side of the elbow member 5. Thereby, the flow path 4a can be formed between the lower end edge of the peripheral wall part 53 in the elbow member 5 and the bottom surface of the body 41, and the waste water flowing down through the elbow member 5 is separated from the lower end edge of the peripheral wall part 53. The water overflows from the upper end edge serving as the outlet 4 b of the rod body 41 through the flow passage 4 a between the bottom surface of the body 41 and flows out to the drain pipe P. At this time, the sealing water is secured by the height of the body 41.

  In addition, although the screw connection by the external thread and the internal thread was demonstrated as a connection structure of the cylindrical member 21 and the flange member 22 which comprise the cylinder 2 for fixation, it is not restricted to a screw connection, For example, it is notched in one peripheral edge. In addition, a projecting piece corresponding to the notch is formed on the other side, and the projecting piece is inserted into the notch and dropped, and the set angle is rotated to prevent the projecting piece from being detached so that they are integrally connected. It may be.

  Further, the fixing cylinder 2 is not limited to being colorless and transparent, and may be colored transparent or translucent colored with yellow, red, blue, or the like, as long as the connection state with the drain pipe P can be confirmed.
