The cylindrical member is formed so that the width of the slit gradually increases from a predetermined part to the end of the cylindrical member (except for a structure engaged with a male screw of the piping support suspension bolt). Is.
In addition, as described in claim 5, the pipe fluid identifying tool according to the present invention is a pipe fluid identifying tool for identifying the type of fluid flowing in the pipe.
A pipe-supporting suspension bolt that is composed of a cylindrical member made of an elastic material having slits formed along the material axis direction, and that elastically deforms the cylindrical member so that the slit expands, thereby suspending the pipe. Is inserted into the inner space of the tubular member through the slit, and the tubular member is held by the piping support suspension bolt with a restoring force to return to the state before elastic deformation. In addition, a flange-like annular rib is provided at each end of the tubular member so as to project outward from the tubular member .

  In the pipe fluid identification tool according to the present invention, the cylindrical member is formed such that the width of the slit gradually increases from a predetermined portion to an end of the cylindrical member.

  Moreover, the identification tool for the fluid in the pipe according to the present invention is configured to identify the fluid type of the pipe by the appearance of the cylindrical member.

  In the pipe fluid identification tool according to the present invention, the appearance is a color associated with the type of fluid.

  In the identification tool for fluid in a pipe according to the present invention, the mounting destination is not a pipe or a suspension band, but a suspension bolt for supporting a pipe for holding a pipe, and a slit is formed along the material axis direction. It is composed of a cylindrical member made of an elastic material, and by expanding the slit, more specifically, the cylindrical member is elastically deformed so that the slit expands, so that a suspension bolt for supporting a pipe through the slit is formed. Is inserted into the inner space of the tubular member, and the tubular member is held by the piping support suspension bolt with a restoring force from its expanded state, more specifically with a restoring force to return to the state before elastic deformation. It has become so.

  In this way, the installation work to the piping support suspension bolt is completed instantly and there is no possibility of dropping off after installation, so that it is possible to efficiently realize the state in which the fluid type of the pipe can be identified, and the identifiable state It is also possible to reliably maintain this.

  The slit is typically formed so that the width thereof is substantially the same from one end to the other end of the cylindrical member, but as long as the slit is formed along the material axis direction of the cylindrical member. However, it is not always necessary to form the same width from one end to the other end.

  In particular, in the configuration in which the cylindrical member is formed so that the width of the slit gradually increases from a predetermined part to the end of the cylindrical member, the width of the slit is maximized at the end of the cylindrical member. If the cylindrical member is pushed into the piping support suspension bolt in a posture in which the part is in contact with the peripheral surface of the piping support suspension bolt, the force required for insertion is small as the slit width is large. Workability during installation is improved.

  In this configuration, among the slits, a length range in which the width is constant along the material axis direction of the cylindrical member is a standard slit portion, and a length range in which the width gradually increases and widens is an expanded slit portion. Then, the expansion slit part may be provided at one end of the cylindrical member, or may be provided at each end. Incidentally, the boundary between the standard slit portion and the expanding slit portion is a predetermined portion of the cylindrical member described above.

  The state in which the fluid type of the pipe can be identified is also possible, for example, by hanging an identification plate configured to identify the type of fluid in the pipe on a hook protruding from the cylindrical member. The cylindrical member performs only the mounting function for mounting the identification plate to the piping support suspension bolt, and the identification function is handled by the identification plate. However, the pipe type is identified by the appearance of the cylindrical member. If comprised in this, a cylindrical member will have both an attachment function and an identification function, and it will become possible to implement | achieve the discrimination | determination state of a fluid classification still more efficiently.

  The appearance of the cylindrical member includes shapes such as length and thickness, but if this is a color associated with the type of fluid, it can be easily seen from a distance and the shape is uniform. Therefore, it can be manufactured at a low cost, and is excellent in handling during storage and transportation.

  For example, the color composition is blue for cold water, yellow-green for cold / hot water, yellow-red for hot water, green for cooling water, green for make-up water, light purple for hot water supply, light blue for water supply, fire extinguishing Can be red.

  As long as the tubular member can be inserted into the inner space through the slit and the piping support suspension bolt can be held with a restoring force to return to the state before elastic deformation, the length and thickness of the tubular member can be increased. The cross-sectional shape is not limited and may be a circular cross-section, but the cylindrical member may have a slit on its long axis so that the cross-section is elliptical. If it is formed so as to be positioned, the outer peripheral surface of the suspension bolt for supporting the pipe can be covered more widely than when the cross section is circular. It becomes possible to reliably identify the fluid type.

  Here, if a fitting groove having a curved cross section extending along the material axis of the tubular member is disposed on the inner peripheral surface of the tubular member and extending along the material axis of the tubular member, the pipe supporting suspension bolt is thin. Even if it is a diameter, since the suspension bolt for pipe support fits into the fitting groove, the cylindrical member is firmly held by the suspension bolt for idle pipe support without causing rattling or play.

  In addition, if a flange-shaped annular rib is provided at each end of the tubular member, when mounting a plurality of pipe-identifying devices for pipe fluid according to the present invention on the suspension bolt for pipe support, Since the ends do not overlap each other, it is possible to prevent the workability from being deteriorated during mounting.

  Further, if the vertical ribs are provided at the opposing edge portions sandwiching the slit of the cylindrical member so that the opposing surfaces are at an angle of 60 ° or more and 80 ° or less, the opposing surfaces of the vertical ribs are formed on the pipe supporting suspension bolts. Since it can be pushed in while sliding on the outer peripheral surface, it becomes possible to easily insert the pipe supporting suspension bolt into the internal space of the tubular member.

  Here, the reason why the facing surface is set to 60 ° or more and 80 ° or less is that when the angle is within this range, the facing surface of the vertical rib is easily brought into contact with the outer peripheral surface of the piping support suspension bolt.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a pipe fluid identification tool according to the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a front view showing a pipe fluid identification tool 1 according to the present embodiment together with a pipe support suspension bolt 2 to which the pipe fluid identification tool is attached. The upper end of the suspension band is attached to the lower surface of a ceiling or an upper floor slab (not shown), and the lower end of the suspension band 4 is connected to the lower end of the suspension band 4 via a connector 3. By inserting the pipe 6 into the pipe 5, the pipe can be suspended from the ceiling or the upper floor slab.

  FIG. 2 is an overall perspective view showing the fluid identification tool 1 in the pipe, and FIG. 3 is a sectional view and an arrow view. As can be seen from these drawings, the pipe fluid identification tool 1 is composed of a cylindrical member 12 made of an elastic material in which slits 11 are formed along the material axis direction. By elastically deforming the cylindrical member 12 so that the slit 11 expands, the pipe supporting suspension bolt 2 is inserted into the inner space of the cylindrical member 12 through the slit, and the cylindrical member expands. The pipe supporting suspension bolt 2 is restored by the restoring force to return to the original state shown in FIGS. 3B and 3C from the radial state, that is, the restoring force to return the cylindrical member 12 to the state before elastic deformation. It is supposed to be retained.

  What is necessary is just to form the identification tool 1 of the fluid in piping by resin materials, such as a polypropylene.

  The cylindrical member 12 is formed so that the cross section thereof is elliptical and the slit 11 is positioned on the long axis thereof, and a hook-shaped annular rib is formed at each end of the cylindrical member 12. 13 and 13 are provided so that the end portions of the cylindrical member 12 do not overlap each other when a plurality of pipe identifying pipes 1 are attached to the pipe supporting suspension bolt 2.

  In addition, longitudinal ribs 14 and 14 are provided at opposite edges of the cylindrical member 12 across the slit 11 so as to extend from one of the annular ribs 13 and 13 to the other.

  In the present embodiment, the vertical ribs 14 and 14 are formed to have an angle of approximately 70 ° so that the opposing surfaces form an angle of 60 ° or more and 80 ° or less, and the cylindrical member 12 through the slit 11 is formed. The piping support suspension bolt 2 can be smoothly inserted into the inner space.

  The cylindrical member 12 is colored with a color associated with the type of fluid, and the fluid type of the pipe 6 can be identified by the appearance of the cylindrical member.

  For example, the color composition is blue for cold water, yellow-green for cold / hot water, yellow-red for hot water, green for cooling water, green for make-up water, light purple for hot water supply, light blue for water supply, fire extinguishing Should be red.

  FIG. 4 shows a case where the pipe supporting suspension bolt 2 is a small diameter pipe supporting suspension bolt (FIG. 4 (a)) and a case of a large diameter pipe supporting suspension bolt (FIG. 4 (b)). It is the cross-sectional view which showed a mode that the identification tool 1 of the fluid in a piping which concerns on this embodiment was each mounted | worn to this each piping support suspension bolt.

  As shown in the figure, in order to attach the pipe fluid identification tool 1 to the pipe support suspension bolt 2 according to this embodiment, the slit 11 of the tubular member 12 faces the pipe support suspension bolt 2. Then, the pipe 1 is grasped by the pipe 1 and the opposing surfaces of the vertical ribs 14 and 14 of the cylindrical member 12 are pressed against the outer peripheral surface of the pipe supporting suspension bolt 2 (FIG. 2A). , (B), upper stage), it is only necessary to push it into the side of each pipe supporting suspension bolt.

  As a result, the slit 11 of the tubular member 12 is expanded (the middle stage of FIGS. 1A and 1B), and the piping support suspension bolt 2 is inserted into the inner space of the tubular member 12 through the slit. (The lower part of the figure (a), (b)), and the pipe supporting suspension bolt 2 with the restoring force to return the cylindrical member to the original state (the upper part of the figure (a), (b)) Retained.

  As described above, according to the pipe fluid identification tool 1 according to the present embodiment, the mounting destination is not the pipe 6 or the suspension band 5 but the pipe support hanging bolt 2 that holds the pipe 6. The piping supporting suspension bolt 2 is inserted into the inner space of the tubular member 12 through the slit 11 of the tubular member 12, and the restoring force of the tubular member to return from the expanded state to the original state. Therefore, the mounting operation to the piping support suspension bolt 2 is instantaneously completed and there is no possibility of dropping off after the mounting.

  Therefore, it is possible to efficiently realize a state in which the fluid type of the pipe 6 can be identified, and to reliably maintain the identifiable state.

  Further, according to the fluid identification tool 1 in the pipe according to the present embodiment, since the fluid type of the pipe 6 is identified by the appearance of the tubular member 12, the tubular member 12 has an attachment function and an identification function. Therefore, it is possible to efficiently realize a fluid type discriminable state.

  In addition, according to the fluid identification tool 1 in the pipe according to the present embodiment, since the appearance of the cylindrical member 12 is a color associated with the type of fluid, the shape can be easily seen from a remote location. Since it can be made uniform, it can be manufactured at low cost, and is excellent in handling during storage and transportation.

  In addition, according to the fluid identification tool 1 in the pipe according to the present embodiment, the cylindrical member 12 is formed so that its cross section is elliptical and the slit 11 is positioned on its long axis. The outer peripheral surface of the piping support suspension bolt 2 can be covered more widely than when the cross section is circular.

  Therefore, the visibility of the cylindrical member 12 is increased, and as a result, the fluid type of the pipe 6 can be reliably identified.

  That is, when the cylindrical member is configured so that the cross-section is circular, the correspondence between the large diameter and the small diameter in the identification tool for the fluid in the pipe is the circumferential direction as shown in FIG. If the configuration for identifying the fluid in the pipe according to the present invention is configured so that the outer peripheral surface is sufficiently covered with the large-diameter pipe-supporting suspension bolt. (Right side of the figure) When applied to a suspension pipe for small diameter pipe support (left side of the figure), the inner peripheral surface of the cylindrical member is for pipe support because the opposing edges of the cylindrical member come into contact with each other first. A gap is generated without coming into contact with the outer peripheral surface of the suspension bolt, and as a result, a situation in which the suspension bolt is not held by the piping support suspension bolt occurs.

  Therefore, considering the case of applying to a small-diameter pipe support suspension bolt, the outer peripheral surface of the large-diameter pipe support suspension bolt cannot be sufficiently covered, and the identification tool for the fluid in the pipe is visually recognized from all directions. It can be difficult.

  On the other hand, in the case of the pipe identification member 1 of the present embodiment in which the tubular member 12 is configured to have an elliptical cross section, as shown in FIG. When the bolt 2 has a small diameter (left side in the figure), it is sufficient that the outer peripheral surface of the bolt 2 is held back-to-back, and on the fluid identification device 1 side in the short axis direction at two points. In the axial direction, the extra length in the major axis direction can be absorbed by being separated from the outer peripheral surface of the pipe support suspension bolt 2, so that the outer peripheral surface is sufficient when the pipe support suspension bolt 2 has a large diameter. Even if it is configured so as to be covered with, there is no problem in application to a suspension bolt for supporting a small-diameter pipe.

  Further, according to the pipe fluid identification tool 1 according to the present embodiment, since the hook-shaped annular ribs 13 are provided at each end of the cylindrical member 12, as shown in FIG. Even when a plurality of steps are mounted on the suspension bolt 2, there is no possibility that the mounting operation takes time because the ends of the cylindrical member 12 overlap each other.

    Moreover, according to the fluid identification device 1 in the pipe according to the present embodiment, the longitudinal ribs are formed so as to extend from one of the annular ribs 13 and 13 to the opposite edge portion sandwiching the slit 11 of the tubular member 12. 14 and 14 are provided, it becomes possible to push the opposing surface of the vertical rib while sliding the outer surface of the pipe supporting suspension bolt 2 on the outer periphery of the pipe supporting suspension bolt 2. It can be easily inserted into the internal space.

  In the present embodiment, the vertical ribs 14 and 14 are provided on the opposite edge portions sandwiching the slit 11 of the tubular member 12 in order to enhance the ease of mounting to the piping support suspension bolt 2. If there is no problem, the vertical ribs 14 may be omitted.

  Further, in the present embodiment, it is assumed that the identification device 1 for the fluid in the pipe is attached in a step shape, and a bowl-shaped annular rib 13, 13 is provided, but it is not necessary to assume a plurality of mountings, and even if there is an assumption, if there is no need to worry about overlapping of the end portions, this is also omitted for the annular ribs 13 and 13. It is possible.

  Further, in this embodiment, the cylindrical member is configured so that its cross section is elliptical so that it can be applied to two types of pipe-supporting suspension bolts of large diameter and small diameter, but it can be applied to different diameter sizes. If there is no problem in visibility if the outer peripheral surface of the pipe supporting suspension bolt can be covered about half, the cylindrical member is configured so that its cross section is circular. It doesn't matter.

  In the present embodiment, the appearance of the cylindrical member 12 is the color associated with the type of fluid. However, instead of the color, the type of fluid is changed depending on the shape, for example, the length or thickness of the cylindrical member. You may make it identify.

  In the present embodiment, the tubular member 12 is configured to identify the fluid type of the pipe 6 by the appearance of the tubular member 12, so that the tubular member has both an attachment function and an identification function. It is possible to limit the cylindrical member 12 only to the function of attaching to the piping support suspension bolt 2, and to realize the identification function by another means.

  FIG. 7 shows the tubular member 12 of the present embodiment and the annular ribs 13 and 13 of the tubular member 12a configured in the same manner except for the colored structure. The identification plate 63 configured to be able to identify the fluid type of the pipe 6 can be suspended through the hook by hooking the hook 64 in the insertion hole 62 formed in the latching portion while projecting. It is constituted as follows.

  In such a configuration, the cylindrical member 12a performs only an attachment function for attaching the identification plate 63 to the piping support suspension bolt 2, and the identification plate 63 takes charge of the identification function.

  Although not particularly mentioned in the present embodiment, as shown in FIG. 8 (a), instead of the cylindrical member 12, a material is placed on the short axis of the elliptical cross section at a position opposed to the inner peripheral surface. A cylindrical member 12a in which fitting grooves 71, 71 having a curved cross section extending in the axial direction can be employed.

  According to such a configuration, as shown in FIG. 5B, even if the pipe support suspension bolt 2 has a small diameter, the pipe support suspension bolt fits into the fitting grooves 71, 71, so The member 12a is firmly held by the piping support suspension bolt 2 without rattling or play.

  Since the cylindrical member 12a has the same configuration as the cylindrical member 12 except that the fitting grooves 71 and 71 are provided, detailed description thereof is omitted.

  In the present embodiment, the cylindrical member is formed so that the width of the slit 11 is substantially the same from one end to the other end of the cylindrical member 12, but instead of such a configuration, it is shown in FIGS. 9 and 10. As described above, the cylindrical member 92 is formed by the cylindrical member 92 made of an elastic material having a slit 11a formed in the material axis direction and having a circular cross section, and the cylindrical member 92 so that the slit 11a expands. The piping supporting suspension bolt 2 is inserted into the inner space of the cylindrical member 92 through the slit, and the piping member is restored with a restoring force to return to the state before the elastic deformation. Although it is held by the supporting suspension bolt 2, the slit 11a has a standard slit portion 94 extended so that the width thereof is constant, and one end side of the standard slit portion. The width gradually increases It is constituted by the widened slit portion 93 which extends so as to be rising.

  In such a configuration, since the width of the slit 11a is maximized at the end of the cylindrical member 92, the end of the cylindrical member 92 is brought into contact with the peripheral surface of the piping support suspension bolt 2 as shown in FIG. If the cylindrical member 92 is pushed into the piping support suspension bolt 2 in the posture, the insertion force can be reduced because the width of the slit 11a is large, and the workability during mounting is improved.

  In addition, the structure of the cylindrical member 92 other than the structure related to the slit 11a is substantially the same as that of the cylindrical member 12, and hook-shaped annular ribs 13 and 13 are provided at each end of the cylindrical member 92. In this way, when a plurality of pipe fluid identification tools 91 are attached to the pipe supporting suspension bolt 2 in a stepped manner, the ends of the cylindrical member 92 are not overlapped with each other, and further, the cylindrical member The vertical ribs 14 and 14 are provided on the opposing edge portion sandwiching the slit 11a of 92 so as to extend from one of the annular ribs 13 and 13 to the other, and the opposing surfaces thereof are formed to be approximately 60 °. Thus, the point that the operation of inserting the piping support suspension bolt 2 into the inner space of the cylindrical member 92 via the slit 11a can be performed smoothly is substantially the same as in the above-described embodiment. ,here Omit the details of the description.

  Moreover, in the modification regarding the slit 11a mentioned above, in order to improve the mounting | wearing ease to the piping support suspension bolt 2, the vertical ribs 14 and 14 were provided in the opposing edge part which pinches | interposes the slit 11a of the cylindrical member 92. If there is no problem in the ease of mounting described above, the vertical ribs 14 and 14 may be omitted.

  Further, in this modification, it is assumed that the identification device 91 for the fluid in the pipe is attached in a step shape, and the bowl-shaped annular ribs 13, 13 is provided, but it is not necessary to assume a plurality of mountings, and even if there is an assumption, if there is no need to worry about overlapping of the end portions, this is also omitted for the annular ribs 13 and 13. It is possible.

  In the modification, the cylindrical member 92 is configured to have a circular cross section. However, the cylindrical member 92 needs to be adapted to two types of pipe-supporting suspension bolts having a large diameter and a small diameter. If it exists, it is possible to comprise a cylindrical member so that the cross section may become an ellipse similarly to embodiment mentioned above.

  Further, in the modification, the appearance of the cylindrical member 92 is a color associated with the type of fluid, but instead of the color, the type of fluid varies depending on the shape, for example, the length or thickness of the cylindrical member. You may make it identify.

  In addition, in the modification, the tubular member 92 is configured to identify the fluid type of the pipe 6 according to the appearance of the tubular member 92, so that the tubular member has both an attachment function and an identification function. The cylindrical member 92 is limited only to the function of attaching to the piping support suspension bolt 2, and the identification function can be realized by another means as in the above-described embodiment.
