Description

  The present invention relates to a drainage pipe connector for temporarily placing a drainage pipe in a through hole formed in a floor plate portion of a building.

  Conventionally, a through-hole penetrating in the vertical direction is formed in a floor plate portion (for example, a veranda floor or a balcony floor) that protrudes from an outer wall of a building. And the drain pipe which guides the water (for example, rain water, miscellaneous drainage, etc.) on a floor board part through a through hole is installed in the floor board part.

  However, for example, in a building where various constructions are being performed, a drain pipe may not be installed on the floor plate. In this case, the water that has fallen below the floor plate portion through the through hole may interfere with the work performed below the floor plate portion, or may contaminate the building.

  Therefore, in buildings where various constructions are being performed, drainage pipe connectors that temporarily install drainage pipes in through holes may be used.

  This will be described more specifically. As shown in FIGS. 12 and 13, the drainage pipe connector 4 is a cylindrical connection pipe C disposed in the through hole D <b> 1 and is fixed in the connection pipe C to which the drainage pipe P is connected. A connecting member 40 and a suspension member 41 that can be attached to and detached from the connecting member 40 are provided (for example, see Patent Document 1). In addition, the cylindrical metal fitting D2 is arrange | positioned in the through-hole D1 shown in FIG. 12, FIG.

  The suspension member 41 has a rod shape and a support rod 410 that can be inserted into the connecting pipe C, and a hook member 411 that is rod-shaped and rotatably connected to one end portion in the longitudinal direction of the support rod 410. And it has the latching member 411 whose length in a longitudinal direction is longer than the internal diameter of the said through-hole D1.

  In order to temporarily set the drainage pipe P by the drainage pipe connector 4, first, the latching member 411 is rotated so that the latching member 411 and the support rod 410 can be inserted into the through hole D1. Then, the latch member 411 and the support rod 410 are inserted into the through hole D1 from below the floor plate portion F, and the latch member 411 is further disposed above the floor plate portion F.

  And after making the longitudinal direction of the latching member 411 orthogonal or substantially orthogonal to the longitudinal direction of the support rod 410, the latching member 411 is latched around the through hole D1 on the upper surface of the floor plate portion F. As a result, the suspension member 41 is suspended from the floor plate portion F.

  And if the connection member 40 is attached to the suspension member 41, the connection pipe C will be maintained in the state arrange | positioned in the through-hole D1. Thereby, the said drain pipe connector 4 will be in the state which can install the drain pipe P temporarily.

Japanese Patent No. 3325484

  By the way, in the drainage pipe connector 4 attached to the floor board part F, the connecting member 40 is attached to the suspension member 41 suspended from the floor board part F. Therefore, when removing the drainage pipe connector 4 from the floor plate portion F, the connecting member 40 and the suspension member 41 are recovered from below the floor plate portion F after the hooking member 411 is removed from the floor plate portion F. .

  As described above, when the drainage pipe connector 4 is removed from the floor plate portion F, it is necessary to perform an operation above the floor plate portion F and below the floor plate portion F. Is a problem.

  Then, an object of this invention is to provide the drainage pipe connector which can be removed from a floor board part without taking an effort in view of such a situation.

  The drainage pipe connector according to the present invention is a through-hole formed in a floor board portion protruding from the outer wall of a building, and water on the floor board portion is passed through a through-hole penetrating the floor board portion in the vertical direction. In the drainage pipe connector for temporarily setting the drainage pipe to be guided downward, a cylindrical connection pipe disposed in the through hole, and a coupling member fixed in the connection pipe to which the drainage pipe is connected; A suspension member that can be attached to and detached from the connecting member, the suspension member being in a rod shape and penetrating the connecting pipe, and one end portion in the longitudinal direction of the rod and the support rod. The latch member is rotatably connected to the latch member, and has a latch member whose length in the longitudinal direction is longer than the inner diameter of the through hole, and an operation portion extending from the latch member.

  According to the drainage pipe connector having the above configuration, the hanging member is rotatably connected to the first end portion of the support rod, so that the state of the hanging member can be changed by changing the posture of the hanging member. Can be switched between a state in which the longitudinal direction of the support rod corresponds or substantially corresponds to the longitudinal direction of the latch member, and a state in which the longitudinal direction of the support rod is orthogonal or substantially orthogonal to the longitudinal direction of the latch member.

  And since a support rod and a latching member are rod-shaped which can be inserted in a connecting pipe (through hole), it becomes possible to insert in a through hole by making each longitudinal direction correspond or substantially correspond.

  Further, in the suspension member, since the length in the longitudinal direction of the latching member is longer than the inner diameter of the through hole, the latching member is made by making the longitudinal direction of the latching member orthogonal or substantially orthogonal to the longitudinal direction of the support rod. Can be hooked around the through hole in the upper surface of the floor plate portion.

  Further, in the drainage pipe connector, since the suspension member has an operation part extending from the latching member, when the latching member is latched around the through hole in the upper surface of the floor plate part, the manipulation part becomes the latching member. Can be hung. Therefore, in the said drainage pipe connector, a latching member can be rotated by operating an operation part from the downward direction of a floor board part. That is, in the drainage pipe connector, the attitude of the retaining member can be changed from below the floor plate portion.

  Therefore, the said drainage pipe connector can perform the operation | work which removes a connection member from a suspension member, and the operation | work which removes a suspension member from a floor board part under a floor board part. Therefore, the drainage pipe connector can be removed from the floor plate portion without taking time and effort.

  As one aspect of the drainage pipe connector according to the present invention, the connection member includes a base portion fixed to the connection pipe and an engagement portion formed on the base portion, and supports the suspension member. The rod has an engaged portion that engages with the engaging portion, and at least one of the engaging portion and the engaged portion is spaced in the insertion direction of the support rod with respect to the connection pipe. A plurality of them may be formed.

  According to such a configuration, since at least one of the engaging portion and the engaged portion is formed in plural in the insertion direction of the support rod with respect to the connection pipe, a connecting member is formed in the insertion direction. Can be adjusted. That is, the drain pipe connector can adjust the position where the connection pipe is arranged in the insertion direction. Therefore, the drain pipe connector having the above-described configuration can adjust the position where the connection pipe is arranged according to the floor plate part to be attached and the through hole.

  As another aspect of the drainage pipe connector according to the present invention, the suspension member allows rotation in one direction in the rotation circumferential direction of the latching member and extends in the other direction in the rotation circumferential direction of the latching member. A rotation-preventing portion capable of restricting rotation, wherein the rotation portion is fixed to one of the support rod and the latch member, and the longitudinal direction of the support rod and the longitudinal direction of the latch member are orthogonal to each other. You may make it have a rotation stop part contact | abutted in any one of a support rod and the said latching member.

  According to such a configuration, the suspension member is fixed to one of the support rod and the latch member, and the support rod and the latch member are arranged in a state where the longitudinal direction of the support rod and the longitudinal direction of the latch member are orthogonal to each other. It has a rotation stop part which contacts either one. For this reason, if the longitudinal direction of the latching member is orthogonal to the longitudinal direction of the support rod by rotating the latching member in the other direction in the circumferential direction of rotation, the rotation portion is applied to either the support rod or the latching member. Touch.

  Thereby, in a latching member, in the state which can be latched around the through-hole in the upper surface of a floor board part, the rotation to the other direction in a rotation circumferential direction is controlled. Therefore, the drainage pipe connector can be easily changed to a posture in which the hooking member can be hooked around the through hole in the upper surface of the floor plate portion.

  As another aspect of the drain pipe connector according to the present invention, the suspension member has a biasing member that biases the hooking member in one direction in the rotational circumferential direction or in the other direction in the rotational circumferential direction. It may be.

  According to this configuration, the posture of the latching member can be changed by rotating the latching member against the biasing force of the biasing member. And if operation with respect to an operation part is cancelled | released, the attitude | position of a latching member will return to the original attitude | position with the urging | biasing force of an urging | biasing member. Therefore, in the drainage pipe connector, it is possible to save the trouble of returning the posture of the hooking member.

  As still another aspect of the drainage pipe connector according to the present invention, the suspension member may include a biasing member that biases the hooking member toward another direction in the rotation circumferential direction.

  In this way, since the latching member is urged in the other direction in the rotational circumferential direction by the urging member, the urging force of the urging member is applied to the latching member rotated in one direction in the rotational circumferential direction. Works. Therefore, when the operation with respect to the operation portion is released in a state where the longitudinal direction of the latching member corresponds or substantially corresponds to the longitudinal direction of the support rod, the latching member rotates in the other direction in the rotational circumferential direction. And when the longitudinal direction of a latching member is orthogonal to the longitudinal direction of a support rod, rotation to the other direction in the rotation circumferential direction of a latching member is controlled by a rotation part.

  Therefore, the drainage pipe connector can easily change the posture of the hooking member to a posture that can be hooked around the through hole in the upper surface of the floor plate portion without operating the operation portion.

  As described above, according to the drainage pipe connector of the present invention, it is possible to achieve an excellent effect that the drainage pipe connector can be detached from the floor plate portion without taking time and effort.

And a retaining portion 321 for retaining the first end of the operation portion main body 320.

  The operation unit main body 320 is long. The first end of the operation unit main body 320 is bent. Therefore, the first end portion of the operation unit main body 320 extends in the direction perpendicular to the surface with respect to the hooking member 31. Therefore, the operation portion main body 320 can be rotated relative to the latch member 31 with the first end portion as the rotation center.

  In the present embodiment, the operation portion 32 is disposed at a position shifted from the center in the longitudinal direction of the latching member 31 to the first end side of the latching member 31. Therefore, the contact piece 331 is disposed at a position shifted from the center in the longitudinal direction of the latch member 31 to the second end side of the latch member 31.

  The connection tool 1 according to the present embodiment is as described above. Subsequently, a method for temporarily setting the drain pipe P by the connector 1 according to the present embodiment will be described with reference to the drawings.

  In the present embodiment, when connecting the through hole D1 and the drain pipe P with the connector 1, the suspension member 3 is attached to the through hole D1.

  This will be described more specifically. First, the latch member 31 is rotated in one direction in the rotation circumferential direction by operating the operation unit 32. The longitudinal direction of the latch member 31 corresponds or substantially corresponds to the longitudinal direction of the support rod 30. Thereby, the latch member 31 and the support rod 30 can be inserted through the through hole D1.

  Then, the latch member 31 and the support rod 30 are inserted into the through hole D1 from below the floor plate portion F, and the latch member 31 is disposed above the through hole D1, as shown in FIG. After doing in this way, by operating the operation part 32, the latching member 31 is rotated in the other direction in the rotation circumferential direction.

  When the longitudinal direction of the latching member 31 is orthogonal or substantially orthogonal to the longitudinal direction of the support rod 30, the rotation stop portion 33 comes into contact with the latching member 31. Thereby, in the latching member 31, in the state which can be latched around the through-hole D1 in the upper surface of the floor-plate part F, the rotation to the other direction in a rotation circumferential direction is controlled. And as shown in FIG. 6, the 1st end part of the latching member 31 and the 2nd end part of the latching member 31 are latched around the through-hole D1.

  At this time, the operation unit 32 and the support rod 30 are suspended from the latch member 31. And the operation part 32 and the support rod 30 are extended below the floor board material from the through-hole D1, in the state suspended by the latching member 31. As shown in FIG.

  And while inserting each of the support rod 30 and the operation part 32 in the cylindrical part C10 of the connection pipe C, this cylindrical part C10 is arrange | positioned in the through-hole D1.

  Further, as shown in FIG. 7, the connecting member 2 is fixed to the support rod 30. This will be described more specifically. First, the support rod 30 is inserted between the engagement portion 21 and the frame portion 22 from the second end portion. And as shown in FIG. 8, the 2nd nail | claw part 211 and the 1st nail | claw part 210 are penetrated to the penetration hole of the support rod 30. FIG. If it does in this way, the 2nd nail | claw part 211 will be hooked on the to-be-engaged part 300 of the support rod 30, and the connection pipe C will be fixed to the support rod 30. FIG.

  Thereby, the state arrange | positioned in the through-hole D1 of the connection pipe C is maintained. Therefore, the connector 1 is in a state where the drain pipe P can be temporarily installed (see FIG. 7).

  In order to remove the connection tool 1 from the through hole D1, first, the connecting member 2 is removed from the suspension member 3 (support rod 30). This will be described more specifically. First, each of the first claw part 210 and the second claw part 211 is removed from the insertion hole of the support rod 30. If it does in this way, fixation of connecting member 2 and support rod 30 will be canceled. Then, the connecting pipe C is moved downward. Thereby, the connecting pipe C is removed from the suspension member 3.

  Accordingly, in the suspension member 3, the operation portion 32 and the support rod 30 suspended from the hooking member 31 are exposed downward from the through hole D1. And the latching member 31 is arrange | positioned rather than the through-hole D1 by moving the support rod 30 and the operation part 32 upward.

  Furthermore, by operating the operation part 32, the latching member 31 is rotated. In this embodiment, the latch member 31 is rotated in one direction in the rotation circumferential direction.

  In this way, the longitudinal direction of the latching member 31 corresponds or substantially corresponds to the longitudinal direction of the support rod 30 so that the latching member 31 and the support rod 30 can be inserted into the through hole D1.

  And the latching member 31 is pulled out to the downward direction of the floor-plate part F from the inside of the through-hole D1 by moving the operation part 32 and the support rod 30 below. Thereby, the suspension member 3 is removed from the through hole D1.

  As described above, the connector 1 according to this embodiment can perform the operation of removing the connecting member 2 from the suspension member 3 and the operation of removing the suspension member 3 from the floor plate portion F below the floor plate portion F. Therefore, it can be removed from the floor board portion F without taking time and effort.

  This will be described more specifically. In the connector 1, the hooking member 31 is rotatably connected to the first end of the support rod 30, so that the state of the hanging member 3 is supported by changing the posture of the hooking member 31. Switching between the state in which the longitudinal direction of the hook 30 corresponds or substantially corresponds to the longitudinal direction of the latching member 31 and the state in which the longitudinal direction of the support rod 30 is orthogonal or substantially orthogonal to the longitudinal direction of the latching member 31. it can.

  And since the support rod 30 and the latching member 31 are rod shapes which can be inserted in the connecting pipe C (through hole D1), they can be inserted into the through hole D1 by corresponding or substantially corresponding to the respective longitudinal directions. Become.

  Furthermore, in the suspension member 3, since the length in the longitudinal direction of the latching member 31 is longer than the inner diameter of the through hole D1, the longitudinal direction of the latching member 31 is orthogonal or substantially orthogonal to the longitudinal direction of the support rod 30. Thus, the hooking member 31 can be hooked around the through hole D1 on the upper surface of the floor plate portion F.

  In the connector 1, the suspension member 3 has the operation part 32 extending from the hooking member 31. Therefore, when the hooking member 31 is hooked around the through hole D <b> 1 on the upper surface of the floor plate part F, the operation part 32. Is suspended from the retaining member 31. Therefore, in the connection tool 1, the latch member 31 can be rotated by operating the operation unit 32 from below the floor plate portion F. That is, in the connection tool 1, the posture of the latch member 31 can be changed from below the floor plate portion F.

  Moreover, since the to-be-engaged part 300 is formed with two or more intervals in the insertion direction with respect to the connection pipe C of the support rod 30, the connection tool 1 can adjust the position of the connection member 2 in this insertion direction. . That is, the connection tool 1 can adjust the position where the connection pipe C is arranged in the insertion direction. Therefore, the connection tool 1 can adjust the position which arrange | positions the connection pipe C according to the floor-plate part F used as attachment object, or the through-hole D1.

  Further, the connector 1 is supported in a state where the suspension member 3 is fixed to one of the support rod 30 and the latch member 31 and the longitudinal direction of the support rod 30 and the longitudinal direction of the latch member 31 are orthogonal to each other. It has the rotation stop part 33 which contact | abuts either the collar 30 or the latching member 31. Therefore, when the latching member 31 is rotated in the other direction in the rotation circumferential direction so that the longitudinal direction of the latching member 31 is orthogonal to the longitudinal direction of the support rod 30, either the support rod 30 or the latching member 31 is moved to the other. The rotation stop 33 comes into contact.

  Thereby, in the latching member 31, in the state which can be latched around the through-hole D1 in the upper surface of the floor-plate part F, the rotation to the other direction in a rotation circumferential direction is controlled. Therefore, the connector 1 is easy to change the posture in which the hooking member 31 can be hooked around the through hole D1 on the upper surface of the floor plate portion F.

  Moreover, in the connector 1, since the latching member 31 arrange | positioned above the floor-plate part F can be rotated by operating the operation part 32 as mentioned above, the suspension member 3 is set to the floor-plate part F.
