Description

  The present invention relates to a cutting position indicator.

  In piping construction on the wall surface of a building, the pipe is connected to the joint arranged on the wall surface by inserting the end of the pipe from the opening end of the joint to the insertion position inside the joint. Incidentally, the pipe before being connected to the joint is fixed at a predetermined fixing position in the longitudinal direction, and is longer than the distance from the fixing position to the joint insertion position. For this reason, the operation | work which connects a pipe to a coupling is performed as follows, for example.

  That is, from the fixed position to the insertion position in the joint by measuring the distance from the fixed position to the joint opening end and adding the length from the opening end to the insertion position in the joint to the measured distance. Distance (hereinafter referred to as cutting distance). Then, the pipe is cut so that the length of the pipe from the fixed position becomes a value corresponding to the cutting distance, and the end of the pipe thus cut is inserted from the opening end of the joint to the insertion position.

  In addition, when inserting the end of the pipe from the opening end of the joint to the insertion position, in order to confirm whether or not the insertion is properly performed, the pipe before insertion is used by using the marking members shown in Patent Documents 1 and 2. It is conceivable to make a marking on the outer peripheral surface. The marking member is for marking used at the time of the confirmation at a position corresponding to the joint opening end on the outer peripheral surface of the pipe when the pipe is inserted from the joint opening end to the insertion position. .

  If the outer peripheral surface of the pipe is marked in advance using the marking member, whether or not the opening end of the joint overlaps the marking on the outer peripheral surface of the pipe when the end of the pipe is inserted from the opening end of the joint Thus, it can be confirmed whether or not the end of the pipe has been inserted up to the insertion position.

  In the above piping construction, by marking the outer peripheral surface of the pipe with a marking member, the end of the pipe can be reliably inserted from the opening end of the joint to the insertion position. However, it is necessary to measure the distance from the fixing position of the pipe to the insertion position in the joint to obtain the above cutting distance, and to cut the pipe to an appropriate length according to the cutting distance. There is a problem that the work is complicated because it takes time and effort.

  The objective of this invention is providing the cutting position indicator which can simplify the operation | work at the time of cut | disconnecting the pipe connected to a coupling.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
The cutting position indicator that solves the above-mentioned problem is for instructing the cutting position of a pipe inserted from the open end of the joint to the insertion position in the joint, and an attachment portion attached to the joint or the pipe; A reference portion provided at the attachment portion and aligned with the reference position of the joint; and a position provided at the attachment portion and corresponding to the insertion position of the joint when the reference portion is aligned with the reference position. And an indicator for indicating the cutting position of the pipe outside the joint.

  When connecting the pipe fixed at a predetermined fixing position to the joint, the cutting position indicating tool has an appropriate length according to the distance (cutting distance) from the fixing position of the pipe to the insertion position of the joint. Used when cutting. When the pipe is cut to an appropriate length using the cutting position indicator, the end of the cut pipe is inserted from the open end of the joint to the insertion position in the joint.

  When the pipe is cut into an appropriate length using the cutting position indicator, first, the attachment portion of the cutting position indicator is attached to either the joint or the pipe. Below, the method of cutting the pipe using the cutting position indicator will be described separately for the case where the attachment portion of the cutting position indicator is attached to the joint and the case where it is attached to the pipe.

  When the attachment portion of the cutting position indicator is attached to the joint, the attachment is performed so that the reference portion is positioned corresponding to the reference position of the joint. At this time, the indicating portion of the cutting position indicating tool is in a state of being positioned corresponding to the insertion position of the joint outside the joint. Under this state, the pipe is arranged so as to extend from the reference portion of the cutting position indicating tool toward the indicating portion, and the pipe is cut using the position indicated by the indicating portion as the cutting position. Note that such pipe cutting may be performed directly at the cutting position indicated by the instruction unit, or may be performed using the same marking as a guide after marking the cutting position.

  On the other hand, when the attachment portion of the cutting position indicator is attached to the pipe, the pipe after the attachment portion is attached is arranged along the joint so as to extend from the opening end of the joint toward the insertion position. And the attachment position of the said attachment part with respect to a pipe is adjusted so that the indicator of a cutting position indicator may be located corresponding to the reference position of a joint. At this time, the indicating portion of the cutting position indicating tool is in a state of being positioned corresponding to the insertion position of the joint outside the joint. In this state, the pipe is cut using the position indicated by the instruction unit as a cutting position. Note that such pipe cutting may be performed directly at the cutting position indicated by the instruction unit, or may be performed using the same marking as a guide after marking the cutting position.

  After cutting the pipe using the cutting position indicator as described above, the end of the cut pipe is inserted from the opening end of the joint to the insertion position. By cutting the pipe using the cutting position indicator, the distance from the fixing position of the pipe to the opening of the joint is measured to obtain the cutting distance, and the pipe is adjusted to an appropriate length according to the cutting distance. The pipe connected to the joint can be cut without performing a complicated work of cutting. Therefore, the work at the time of cutting can be simplified.

Hereinafter, an embodiment of a cutting position indicator will be described with reference to FIGS.
FIG. 1 shows joints 2 and 3 and a pipe 4 piped on a wall surface 1 of a building. The joints 2 and 3 are held with respect to the wall surface 1, and one joint 2 and the other joint 3 are connected by a pipe 4. One end of the pipe 4 (the right end in FIG. 1) is inserted from the open end 2 a of the joint 2 to the insertion position PA in the joint 2. Further, the other end portion (left end portion in FIG. 1) of the pipe 4 is inserted from the opening end 3 a of the joint 3 to the insertion position PB in the joint 3.

  The joints 2 and 3 are thus connected by the pipe 4 as follows. That is, one end of the pipe 4 formed longer than the distance between the insertion position PA of the joint 2 and the insertion position PB of the joint 3 is inserted into the joint 2 from the opening end 2a of the one joint 2. Insert up to PA. At this time, one end of the pipe 4 is a fixing position (corresponding to the insertion position PA of the one joint 2) where the pipe 4 is fixed. Thereafter, the pipe 4 is cut into an appropriate length in accordance with the distance between the insertion position PA of the joint 2 and the insertion position PB of the joint 3 (hereinafter referred to as a cutting distance), and the other end of the pipe 4 after the cutting is cut. The part is inserted from the opening end 3 a of the other joint 3 to the insertion position PB in the joint 3.

  2 and 3 show a cutting position indicating tool 5 for indicating the cutting position of the pipe 4. This cutting position indicator 5 is inserted into one end of the pipe 4 formed longer than the cutting distance from the opening end 2a of one joint 2 to the insertion position PA in the joint 2, and then the pipe 4 This is used when cutting to a suitable length according to the above cutting distance.

  The cutting position indicator 5 includes an attachment portion 8 attached to the joint 3, and a reference portion 9 provided on the attachment portion 8 and aligned with a reference position of the joint 3 (in this example, the position of the opening end 3a). I have. Further, the mounting portion 8 has an instruction portion for instructing the cutting position of the pipe 4 on the outside of the joint 3 as a position corresponding to the insertion position PB of the joint 3 when the reference portion 9 is aligned with the reference position of the joint 3. 10 is provided. The indicating unit 10 is configured so that the distance in the center line L direction from the reference unit 9 is a value corresponding to the distance from the reference position (opening end 3a) of the joint 3 to the insertion position PB. Located away from.

  The mounting portion 8 includes a peripheral wall 11 extending in an arc shape with the center line L as the center. An end wall 12 that is orthogonal to the peripheral wall 11 is formed at one end of the inner peripheral surface of the peripheral wall 11 in the direction in which the central line L extends. A surface of the end wall 12 on the peripheral wall 11 side is the reference portion 9. Further, on the surface of the end wall 12 opposite to the peripheral wall 11, a pair of protrusions 13 that extend in an arc shape and protrude in a direction away from the peripheral wall 11 are formed as in the peripheral wall 11. The arc-shaped outer peripheral surface of the protrusion 13 and the arc-shaped inner peripheral surface of the peripheral wall 11 are formed so as to be located on the same circumferential surface with the center line L as the center.

  A flat plate 14 is formed on the outer peripheral surface of the peripheral wall 11 so as to protrude in a direction opposite to the protrusion 13 and to be parallel to the center line L. The end portion of the flat plate 14 in the protruding direction is the indication portion 10. In addition, a hole 15 is formed in the end portion of the flat plate 14 on the peripheral wall 11 side so that the peripheral wall 11 side surface (reference portion 9) of the end wall 12 can be seen from the outer peripheral surface side of the peripheral wall 11. Yes. The flat plate is so arranged that the distance from the reference portion 9 to the pointing portion 10 in the direction of the center line L becomes a value corresponding to the distance from the reference position (opening end 3a) of the joint 3 (FIG. 1) to the insertion position PB. The length in the protruding direction at 14 is defined.

  FIG. 4 shows a state where the cutting position indicator 5 is stored or carried. As can be seen from FIG. 4, a plurality of cutting position indicators 5 are stacked in the direction of the center line L during storage and carrying. Specifically, a plurality of cutting position indicating tools 5 are arranged on the same center line L, and a predetermined cutting position indicating tool is set in a state where the flat plate 14 of each cutting position indicating tool 5 is shifted around the center line L. 5 is inserted into the inner peripheral surface of the peripheral wall 11 of the other cutting position indicator 5. Thereby, the some cutting position indicator 5 can be piled up in the centerline L direction, and it becomes easy to store and carry these cutting position indicators 5.

  FIG. 5 shows a state when the cutting position indicator 5 is used. The cutting position indicator 5 is used after being removed from the stacked state shown in FIG. When the cutting position indicator 5 is used, one end of the pipe 4 formed longer than the distance between the open end 2a of the joint 2 and the open end 3a of the joint 3 shown in FIG. 2 to the insertion position PA in the joint 2 from the open end 2a. And about the said cutting position indicator 5 removed, as shown in FIG. 5, the reference | standard part 9 of the end wall 12 in the attaching part 8 is located corresponding to the opening end 3a (reference | standard position) of the coupling 3. As shown in FIG. And the inner peripheral surface of the peripheral wall 11 of the attachment part 8 is inserted in the outer peripheral surface around the opening end 3a in the joint 3 so that the instruction | indication part 10 may be located in the joint 3 side with respect to the said opening end 3a.

  Then, the cutting position indicating tool 5 is pushed to the joint 3 side to bring the reference portion 9 into contact with the open end 3a, whereby the cutting position indicating tool 5 is attached to the joint 3. Incidentally, whether or not the reference portion 9 and the opening end 3a are in contact with each other can be visually confirmed through the hole 15. Further, when the cutting position indicator 5 is attached to the joint 3, the cutting position indicator 5 is prevented from dropping from the joint 3. Specifically, when the cutting position indicator 5 is attached to the joint 3, the inner peripheral surface of the peripheral wall 11 of the attachment portion 8 is fitted into the outer peripheral surface around the opening end 3a of the joint 3, and the inner peripheral surface and the outer peripheral surface are fitted. The cutting position indicator 5 is prevented from falling off the joint 3 due to the frictional force between them.

  When the cutting position indicator 5 is attached to the joint 3 as described above, the reference portion 9 is positioned corresponding to the reference position (opening end 3a) of the joint 3, and the indicating portion 10 is the insertion position PB of the joint 3. It will be in the state corresponding to (FIG. 1). In this state, as shown in FIG. 5, the portion near the other end of the pipe 4 is disposed so as to extend from the reference portion 9 of the cutting position indicator 5 toward the indicator 10, and the indicator 10 The pipe 4 is cut using a mark as a guide at the position (cutting position Pc) indicated by. The pipe 4 can be cut directly to the cutting position Pc without marking the cutting position Pc.

  Then, after cutting the pipe 4 as described above, the other end (the end on the cut side) of the pipe 4 is inserted from the open end 3a of the joint 3 to the insertion position PB as shown in FIG. Is done. As a result, the other end of the pipe 4 is connected to the joint 3 held on the wall surface 1, so that the joints 2 and 3 are connected by the pipe 4.

Next, the effect of the cutting position indicator 5 will be described.
(1) If the pipe 4 is cut as described above using the cutting position indicator 5, the distance between the opening end 2a of the joint 2 and the opening end 3a of the joint 3 is measured to obtain the cutting distance, It is not necessary to perform a complicated operation of cutting the pipe 4 to an appropriate length according to the cutting distance. Therefore, it is possible to simplify the cutting operation when cutting the pipe 4 in order to connect the other end of the pipe 4 to the joint 3.

  (2) When the cutting position indicator 5 is attached to the joint 3, it is visually confirmed through the hole 15 whether or not the reference portion 9 of the cutting position indicator 5 and the opening end 3 a (reference position) of the joint 3 are in contact with each other. Can be confirmed. For this reason, when the attachment of the cutting position indicator 5 to the joint 3 is incomplete and the reference portion 9 and the opening end 3a are separated from each other, it is confirmed that the cutting position indicator 5 is moved to the joint 3 side. Furthermore, it can push in and the reference | standard part 9 and the opening end 3a can be made to contact.

  (3) Since the reference portion 9 is positioned corresponding to the reference position (opening end 3a) of the joint 3 simply by attaching the cutting position indicator 5 (attachment portion 8) to the joint 3 in this way, The reference portion 9 can be easily aligned.

  (4) A plurality of cutting position indicating tools 5 are arranged on the center line L, and the predetermined cutting position indicating tool 5 is in a state where the flat plate 14 of each cutting position indicating tool 5 is shifted around the center line L. By inserting the outer peripheral surface of the protrusion 13 into the inner peripheral surface of the peripheral wall 11 of the other cutting position indicating tool 5, the plurality of cutting position indicating tools 5 are overlapped in the center line L direction to become one. As described above, by stacking the plurality of cutting position indicating tools 5 into one, the cutting position indicating tools 5 can be easily stored and carried.

  (5) When the cutting position indicator 5 is attached to the joint 3, the cutting position indicator 5 is prevented from dropping from the joint 3. For this reason, when the pipe 4 is cut using the cutting position indicating tool 5, the cutting position indicating tool 5 is dropped from the joint 3, and the cutting position Pc of the pipe 4 indicated by the indicating portion 10 of the cutting position indicating tool 5 is set. There is no possibility that the pipe 4 will not be cut smoothly.

  (6) Since the cutting position indicator 5 can be attached to the joint 3 when the pipe 4 is cut, the operator can freely use both hands during work related to cutting the pipe 4, and thus the piping. The workability during construction is improved.

In addition, the said embodiment can also be changed as follows, for example.
-When one end of the pipe 4 longer than the distance between the open end 2a of the joint 2 and the open end 3a of the joint 3 is connected to the joint 2 and the pipe 4 is wound and stored For example, the portion from the other end of the pipe 4 is curved. In consideration of such bending of the pipe 4, the flat plate 14 of the cutting position indicator 5 may be inclined with respect to the center line L.

  Specifically, as shown in FIG. 6, when the cutting position indicating tool 5 is attached to the joint 3, the flat plate 14 is centered so that the flat plate 14 is separated from the joint 3 as the distance from the opening end 3 a of the joint 3 increases. It may be inclined with respect to L. In this case, since the flat plate 14 can be made to follow the pipe 4 in accordance with the curve of the pipe 4, even if the pipe 4 is curved, the cutting position Pc of the pipe 4 is indicated by the indicator 10 of the flat plate 14. It becomes easy. In this case, the length from the reference portion 9 to the indication portion 10 in the flat plate 14 is a value that takes into account the dimensional difference due to the presence or absence of the bending in the pipe 4.

  In the cutting position indicating tool 5, the flat plate 14 is separated from the attachment portion 8 and is movable to the attachment portion 8 in the direction of the center line L, while the reference portion 9 provided on the attachment portion 8. Instead of this, a reference portion may be provided at an end portion of the flat plate 14 opposite to the indication portion 10. In this case, the flat plate 14 functions as a gauge member that includes the pointing portion 10 and the reference portion and is movable in the direction of the center line L with respect to the mounting portion 8. In the cutting position indicating tool provided with such a gauge member, restrictions on the position and the like when attaching the attachment portion 8 to the joint 3 are reduced. In this cutting position indicating tool, after attaching the attachment portion 8 to the joint 3, the reference portion is aligned with the reference position of the joint 3 by displacing the gauge member (the flat plate 14) in the center line L direction. be able to. When the reference portion is aligned with the reference position of the joint 3, the indicating portion 10 indicates the insertion position PB of the joint 3. Incidentally, compared with such a configuration, in the cutting position indicating tool 5 of the above-described embodiment, it is not necessary to perform an assembling operation of the gauge member to the mounting portion 8 at the time of manufacturing, and the cutting position indicating tool 5 is manufactured along with the work. The process is not complicated.

The cutting position indicating tool may be attached to the pipe 4 in order to indicate the cutting position of the pipe 4.
FIG. 7 shows such a type of cutting position indicator 21. The cutting position indicating tool 21 has a mounting portion 22 whose radial cross section has an arc shape with a curvature corresponding to the outer diameter of the pipe 4, and a reference located on one end surface in the direction in which the center line L of the mounting portion 22 extends. And a pointing portion 24 located on the other end face in the direction in which the center line L of the mounting portion 22 extends. The reference portion 23 is aligned with the opening end 3a (reference position) of the joint 3. The indicator 24 is located away from the reference portion 23 so that the distance from the reference portion 23 becomes a value corresponding to the distance from the open end 3a of the joint 3 to the insertion position PB.

  FIG. 8 shows a state when the cutting position indicator 21 is used. The cutting position indicator 21 is attached to the pipe 4 so that the inner peripheral surface of the attachment portion 22 is in contact with the outer peripheral surface of the pipe 4. At this time, one end of the pipe 4 is connected to the joint 2, and the cutting position indicating tool 21 is attached to a portion of the pipe 4 near the other end. Further, the cutting position indicating tool 21 at this time is attached to the pipe 4 so that the indicating portion 24 is positioned near the reference portion 23 as well as the joint 3 and does not fall off the pipe 4.

  Under the state where the cutting position indicator 5 is attached to the pipe 4, the portion near the other end of the pipe 4 is moved toward the joint 3, and the same portion is moved from the opening end 3 a of the joint 3 to the joint 3. It is arranged to extend toward the side. Further, the attachment position of the cutting position indicator 21 with respect to the pipe 4 is set in the direction in which the pipe 4 extends so that the reference portion 23 of the cutting position indicator 21 is positioned corresponding to the opening end 3 a (reference position) of the joint 3. Adjusted along.

  When the reference portion 23 of the cutting position indicating tool 21 is aligned with the opening end 3a of the joint 3, the indicating portion 24 is positioned corresponding to the insertion position PB (FIG. 1) of the joint 3. In this state, as shown in FIG. 8, the pipe 4 is cut by using a mark at the cutting position Pc indicated by the instruction unit 24 of the cutting position indicator 21 and using the same mark as a guide. The pipe 4 can be cut directly to the cutting position Pc without marking the cutting position Pc. And after cutting the pipe 4 in this way, the other end portion (the end portion on the cut side) of the pipe 4 is inserted from the opening end 3a of the joint 3, whereby the pipe 4 is inserted into the joint 3. The other end is connected, and the joints 2 and 3 are connected by the pipe 4.

  -You may set the reference position of the coupling 3 to positions other than the opening end 3a. For example, as shown in FIG. 9, a position closer to the inside of the joint 3 than the opening end 3a is set as a reference position (PK1 in the figure), or a substantially central position of the joint 3 is set as a reference position (in the figure, as shown in FIG. 10). Or PK2). It should be noted that the reference positions PK1 and PK2 in the joint 3 can be provided with a character display or the like indicating the reference positions PK1 and PK2.

  When the reference position PK1 shown in FIG. 9 is adopted, it is conceivable to use, for example, the cutting position indicating tool 21 shown in FIG. The cutting position indicator 21 is a type attached to the pipe 4, and includes a reference portion 23 that is aligned with the reference position PK 1 of the joint 3, and the joint 3 when the reference portion 23 is aligned with the reference position PK 1. And an instruction section 24 positioned corresponding to the insertion position PB (not shown). Then, the instruction section 24 instructs the cutting position Pc of the pipe 4.

  In addition, when the reference position PK2 shown in FIG. 10 is adopted, it is conceivable to use, for example, the cutting position indicating tool 21 shown in FIG. This cutting position indicator 21 is also of a type that is attached to the pipe 4, and includes a reference portion 23 that is aligned with the reference position PK2 of the joint 3, and the joint 3 when the reference portion 23 is aligned with the reference position PK1. And an instruction section 24 positioned corresponding to the insertion position PB (not shown). Then, the instruction section 24 instructs the cutting position Pc of the pipe 4.

  In addition, it is also possible to provide the mark which shows the reference | standard part 23 and the instruction | indication part 24 in the attachment part 22 of the cutting position indicator 21 shown in FIG.9 and FIG.10. 9 and 10 show an example in which the marks 25 and 26 indicating the reference portion 23 are provided on the mounting portion 22, but instead of the marks 25 and 26, or in addition to the marks 25 and 26, the indication unit 24 is provided. It is also possible to provide a mark to be shown on the mounting portion 22. Incidentally, it is conceivable that these marks are realized by protrusions, recesses, character display, shape change, etc. with respect to the outer surface of the mounting portion 22.

  In the cutting position indicator 21 of the type attached to the pipe 4, a gauge member that is movable in the extending direction of the pipe 4 to which the attachment portion 22 is attached is provided with respect to the attachment portion 22, and is replaced with the reference portion 23 and the indication portion 24. Thus, a reference portion and an instruction portion may be provided in the gauge portion. In this case, after attaching the attachment portion 22 to the pipe 4, the gauge member is displaced with respect to the attachment portion 22 in the extending direction of the pipe 4, thereby aligning the reference portion with the reference position of the joint 3. Can do. When the reference portion is aligned with the reference position of the joint 3, the indicating portion indicates the cutting position Pc of the pipe 4. Therefore, in order to align the reference portion with the reference position of the joint 3, it is not necessary to slide the mounting portion 22 with respect to the pipe 4, and the pipe 4 can be prevented from being damaged during the sliding. Become. Incidentally, in comparison with such a configuration, the cutting position indicating tool 21 shown in FIGS. 8, 9, and 10 does not need to perform an assembling operation of the gauge member to the mounting portion 22 at the time of manufacture, and the cutting is performed in accordance with the operation. The manufacturing process of the position indicator 21 is not complicated.

  -Although the insertion position PA of the joint 2 was illustrated as a fixed position of the pipe 4, the pipe 4 may be fixed with respect to the wall surface 1 in the middle of a longitudinal direction. In this case, the position in the middle of the pipe 4 is a fixed position. The distance from the midway position to the insertion position PB of the joint 3 is a cutting distance that is the distance from the fixing position of the pipe 4 to the insertion position PB of the joint 3.
