  EMBODIMENT OF THE INVENTION The form for implementing the support means which concerns on this invention is demonstrated below based on an Example.

  First, the support means according to the first embodiment will be described with reference to FIGS. 1 and 2A to 2C. As shown in FIG. 1, the fluid pipe 1 of the present embodiment is a water supply pipe laid in an exposed state in the air, and the pipe ends 2a and 2a of adjacent divided pipes 2 and 2, that is, A pipe line is formed by fitting the receiving part and the insertion part to each other and connecting them in the pipe axis direction. Although not particularly illustrated, the fluid pipe 1 is configured by appropriately connecting a straight pipe or a curved pipe, which is each divided pipe, or a fluid valve capable of opening and closing a pipe line, and other connecting members.

  The fluid pipe 1 is supported by a support means 10 provided at predetermined intervals in the pipe axis direction so as to be movable in the pipe axis direction. Each support means 10 is provided at both pipe end portions 2 a and 2 a of each divided pipe 2, and supports each divided pipe 2.

  As shown in FIG. 1 and FIG. 2 (a), each support means 10 is erected on a floor member K made of, for example, concrete as a rigid body along the pipe line, independently of the fluid pipe 1, A stand 12 that supports the divided pipe 2 along the outer periphery of the substantially lower half, a cover 11 that sandwiches the divided pipe 2 between the stand 12 and covers the outer circumference of the upper half, and holds the divided pipe 2 under pressure Bolts and nuts 13 as connecting members that connect the stand 12 and the cover 11 as possible are configured, and the stand 12 and the cover 11 support the outer peripheral surface of the split tube 2 in the circumferential direction.

  As shown in FIG. 2A, more specifically, the stand 12 is an anchor rigidly attached to the floor member K in a through hole 12c formed in the bottom 12a placed on the floor member K. The bolt 4 is inserted and the nut 4 is screwed to fix the floor member K. The curved support portion 12b along the outer peripheral surface of the split tube 2 is surrounded by a dotted line in FIG. As shown in the section, an elastic member 14 made of a rubber plate is laid along the circumferential direction.

  2 (b) and 2 (c), the cover 11 projects in the inner diameter direction at a substantially central portion in the tube axis direction on the inner peripheral surface facing the outer peripheral surface of the split tube 2 in a strip shape. A protruding portion 11 a that contacts the outer peripheral surface of the split tube 2 is provided so as to extend in the circumferential direction of the cover 11.

  Further, taper portions 11b and 11b are formed on both sides of the inner peripheral surface of the cover 11 in the tube axis direction centering on the protrusion portion 11a, and are continuous with the protrusion portion 11a and gradually separated from the outer peripheral surface of the split tube 2. Yes.

  The bolts and nuts 13 are attached at two locations that oppose each other in the radial direction of the split pipe 2, and connect the stand 12 and the cover 11 with the split pipe 2 being clamped. More specifically, the bolt and nut 13 inserts a bolt into an insertion hole formed in each of the side end portion of the stand 12 and the side end portion of the cover 11 facing each other, and screws the nut into the hole. It is tightened with a tightening torque regulated to a force of a predetermined magnitude smaller than that of the conventional tool using a tool such as a torque wrench. Further, the bolt / nut 13 of this embodiment constitutes a so-called double nut in which two nuts are screwed to each bolt, and even if the tightening torque is relatively small as described above, The bolts and nuts are not loosened by the function of the nuts, and the connection state with the predetermined tightening torque smaller than the conventional one is maintained.

  The bolts and nuts 13 of this embodiment connect the stand 12 and the cover 11 with a tightening torque having a predetermined magnitude smaller than that of the conventional one. It does not matter if it is large. Further, the bolt / nut as the connecting member may be, for example, one in which only one nut is screwed to each bolt. Furthermore, for example, the stand and the cover may be connected by a hinge on one side and by a bolt / nut as a connecting member on the other side. The connecting member of the present invention is not limited to bolts and nuts, and may be a well-known fastening member.

  Due to the connection of the bolts and nuts 13, the split tube 2 is in contact with the elastic member 14 laid on the support portion 12 b of the stand 12 and the protruding portion 11 a extending in the circumferential direction on the inner peripheral surface of the cover 11. , Supported by the support means 10.

  The fluid pipe 1 supported by the support means 10 may have a slight movement in the pipe axis direction due to the external force caused by micro-vibration generated by the ground around the fluid pipe 1 and various structures such as bridges. However, according to the structure of the support means 10 of the present invention described above, the split tube 2 is sandwiched between the stand 12 erected on the floor member K as a rigid body and the bolt and nut 13 as a connecting member for connecting the cover 11. By pressing, the elastically deformed elastic member 14 comes into uniform contact with the outer peripheral surface of the split tube 2, so that the contact region between the protrusion 11 a and the split tube 2 is in the tube axis direction of the fluid tube 1. It is maintained unchanged before and after the movement, and can move while being guided along the tube axis by the elastic member 14 and the protrusion 11a without damaging the outer peripheral surface of the fluid pipe 1.

  Further, since each of the divided pipes 2 to which the pipe end portions 2a and 2a are connected to each other is supported by the support means 10, each divided pipe 2 can be moved even if the divided pipes 2 and 2 move relative to each other. Can be supported stably.

  Moreover, since the taper part 11b which followed the protrusion part 11a in the pipe-axis direction is formed gradually spaced apart from the outer peripheral surface of the split pipe 2, the split pipe 2 permitted to move in the pipe-axis direction has the taper part. It can move without touching 11b while staying in contact with the protrusion 11a. In particular, even when the fluid pipe 1 moves in the pipe axis direction slightly inclined with respect to the axis of the support means 10, contact with the tapered portion 11b can be avoided.

  Furthermore, since the taper portions 11b and 11b are formed on both sides in the tube axis direction around the projection portion 11a, the same applies to the case where the divided tube 2 moves in either direction along the tube axis. In addition, it is possible to move without touching the taper portion 11b while staying in contact with the protruding portion 11a.

  Further, the dividing tube 2 can be uniformly supported in the circumferential direction by the protruding portion 11 a extending over the circumferential direction of the cover 11.

  Next, the supporting means according to the second embodiment will be described with reference to FIGS. In addition, about the structure which overlaps with the said Example, the code | symbol same as the said Example is attached | subjected and the description is abbreviate | omitted.

  The cover 21 of the support means 20 of the present embodiment is projected in the inner diameter direction at a substantially central portion in the tube axis direction on the inner peripheral surface facing the outer peripheral surface of the split tube 2 in a strip shape and contacts the outer peripheral surface of the split tube 2. The projecting portions 21a that are in contact with each other extend at a predetermined length in the circumferential direction at a plurality of appropriate locations (two locations in the present embodiment) along the circumferential direction of the cover 21.

  More specifically, each protrusion 21a of the present embodiment is provided adjacent to the non-contact portion 21c formed on the top and both sides of the inner peripheral surface of the cover 21 in the circumferential direction. Each non-contact part 21c is formed in a curved surface shape having a diameter larger than that of the outer peripheral surface of the split tube 2. In the cover 21 of this embodiment, each non-contact part 21c is always separated from the outer peripheral surface of the split tube 2. Installed in a state.

  Tapered portions 21b and 21b are formed on both sides of the inner peripheral surface of the cover 21 in the tube axis direction centering on the respective protrusions 21a, and are continuous with the protrusions 21a and gradually separated from the outer peripheral surface of the split tube 2.

  Thus, by providing a plurality of protrusions 21 a along the circumferential direction of the cover 21, it is possible to appropriately design the contact area depending on the clamping force by the bolts and nuts 13 as the connecting members.

  Next, the support means according to the third embodiment will be described with reference to FIGS. In addition, about the structure which overlaps with the said Example, the code | symbol same as the said Example is attached | subjected and the description is abbreviate | omitted.

  The cover 31 of the support means 30 of the present embodiment has a protrusion 31 a that protrudes in the inner diameter direction and abuts against the outer peripheral surface of the divided tube 2 on the inner peripheral surface facing the outer peripheral surface of the divided tube 2 in a strip shape. At a plurality of appropriate locations along the circumferential direction (5 locations in this embodiment), a predetermined length extends in the tube axis direction.

  More specifically, each protrusion 31a of the present embodiment is provided alternately adjacent to the non-contact portion 31c formed on the inner peripheral surface of the cover 31 in the circumferential direction. Each non-contact part 31 c is formed in a curved surface shape having a larger diameter than the outer peripheral surface of the divided tube 2, and the cover 31 of this embodiment is in a state in which each non-contact part 31 c is separated from the outer peripheral surface of the divided tube 2.
