Japanese Patent Laid-Open No. 11-304052

  In this case, the piping suspension band is brought into the field and used in a shipment form in which the band pieces are integrated by connecting the above-mentioned free ends of the connection and fastening the suspension pieces of the buckle and the band pieces with bolts and nuts. By doing the piping work in the field, screwing the nut of the buckle to the suspension bolt, installing the piping suspension band on the suspension bolt, releasing the connection of the connection free end, and separating the band piece, After temporarily placing and placing the pipe on the band piece for temporarily placing the pipe, the band piece for holding the pipe is rotated around the bolt as a rotation axis so as to connect the two free ends. The piping work on site can be simplified as much as possible.

  However, in this case, the band piece for temporarily placing the pipe has an angle greatly exceeding 180 ° so that the angle of the band piece is about 220 ° so that stable placement of the pipe is possible. Therefore, the width of the opening will be smaller than the diameter of the pipe, and therefore the temporary placement placement of the pipe with respect to the band piece for temporary placement of the plurality of pipe suspension bands installed on the suspension bolt is The reduced opening needs to be elastically pushed and expanded so as to use the elasticity of the piping band and forcedly press-fitted into the band piece so as to be installed on the plurality of piping suspension bands. However, the work of temporarily placing and placing the pipe is performed at a high place, and since the pipe is generally made of steel and has a heavy weight, the work of placing and placing the pipe temporarily becomes complicated.

It is a front view of the band piece for piping holding. It is a side view of the band piece for piping holding. It is a perspective view of a piping suspension band.

  Hereinafter, the present invention will be described in more detail with reference to the drawings. In FIGS. 1 to 5, A is a pipe suspension band formed by pressing a steel plate. A pair of two pieces of band pieces 2a and 2b, which are used for temporarily placing a pipe having a curved angle of ½ yen or more and the other being used for temporarily placing a pipe having a remaining curved angle, are inserted into a hanging piece 22 standing on each upper end thereof. The bolts and nuts 4a and 4b are fastened and supported separately on the suspender 22 of the band piece 2a for separate or temporary pipe placement, and the pipe 6 is temporarily attached by the band piece 2a for temporary pipe placement. The band piece 2b for holding the pipe is rotated in the circumferential direction of the pipe by placing and supporting the two, and the free coupling ends 3 formed on the band pieces 2a and 2b are connected to each other at an intermediate position in the circumferential direction. Split pair of band pieces 2a, 2 In this case, the pipe suspension band A of the present example is in the vicinity of the suspension piece in the bending direction in the band piece 2a for temporarily placing the pipe and the band piece 2b for holding the pipe. The concentric large-diameter portions 25 that are larger in diameter than the inner diameters of the band pieces 2a and 2b and reach the standing position of the upper end of the hanging piece 22 are arranged at the positions.

  The band pieces 2a and 2b of the piping suspension band A include a curved piece 21, a suspended piece 22 at the upper end of the curved piece 21, and a free connecting end 3 at the distal end of the curved piece 21, and have a thickness of about 1.5 mm, for example. For example, the inner diameter is about 3 cm with a radius of about 3 cm.

  At this time, the band piece 2 a for temporary placement of the pipe in the pipe suspension band A is suspended by supporting the band piece 2 a on the tumble buck 1 by the suspension piece 22 and connecting the connection free end 3 to the connection free end 3. In a state where the pipe 6 is partially overlapped, the bending angle from the position of the hanging piece 22 to the tip of the free connecting end 3 is, for example, about 220 °, and the band piece 2b for pipe holding is, for example, about 140 °. The outer periphery of the pipe 6 is covered and supported. At this time, a gap of about 10 ° is generated between the suspended pieces 22 of the band pieces 2a and 2b for temporarily placing the pipe and holding the pipe while the pipe suspension band A is supported by the tambuckle 1. Each of the band pieces 2a and 2b is shortened to an angle of, for example, about 5 ° so that the angle of the gap is absorbed by both of the band pieces 2a and 2b. The band piece 2a for use is provided with a bending angle of about 215 ° in the state of supporting the pipe, and the band piece 2b for holding the pipe is provided with a bending angle of about 135 °. The angle of the curved piece 21 excluding 3 is in the band piece 2a for temporarily placing the pipe, which is less than 200 °, for example, about 190 °, and in the band piece 2b for pipe holding, less than 120 °. For example, about 110 °.

  At the upper end of each band piece 2a, 2b, a hanging piece 22 having a bolt hole 23 through which the bolt 4a is inserted is erected upward. In this example, the bolt hole 23 is used for temporary placement of the pipe. In the band piece 2a, the bolt 4a has a circular shape with a diameter somewhat larger than this, for example, about 7 mm in accordance with an axis of about 6 mm. The bolt hole 23 of the hanging piece 22 arrangement of the band piece 2a for temporary placement of the pipe is aligned with the upper end position, and the lower end is extended downward from the lower end of the bolt hole 23. The length is increased to about 1.3 mm, and a long hole is formed vertically so that the band piece 2b can stand outward in the inserted state of the bolt 4a.

  The free connecting ends 3 of the band pieces 2a and 2b mesh with each other between the step overlapping piece 31 and the tip overlapping piece 33 which are bent so as to overlap each other by the connection, and between the step overlapping piece 31 and the tip overlapping piece 33. The curved pieces 21 of the band pieces 2a and 2b are connected to each other by the cutout grooves 32 each having a ½ width arranged so as to be engaged with each other and the free connection end 3 by the overlapping of the step overlap piece 31 and the tip overlap piece 33. In this example, the tip protrusion 34 is arranged to protrude from the tip overlapping piece toward the inside of the diameter so as to leave a gap of about 1 mm with respect to the inside diameter of the band pieces 2a and 2b. It is assumed that a cut-and-raised protrusion 35 that is fitted and locked to each other so as to prevent both from being detached after the connection free end 3 is connected is provided.

  The band piece 2a for temporarily placing the pipe and the band piece 2b for holding the pipe formed in this way are in this example, and both of them form an arc portion having a diameter larger than the inner diameter of each of the band pieces 2a and 2b. A large-diameter portion 25 is disposed on the surface. The large-diameter portion 25 is provided on the upper part of each of the curved pieces 21 of the band piece 2a for temporarily placing the pipe and the band piece 2b for holding the pipe, that is, the curved piece 21 on the end side opposite to the free connecting end 3. The arrangement is performed so that the inner diameter of each is partially enlarged, and the suspension piece 22 is erected on the upper end thereof. At this time, the large-diameter portion 25 of this example is disposed in common in the position and length (curving angle) of the band pieces 2a and 2b for temporarily placing the pipe and holding the pipe. The large-diameter portion 25 has a bending angle of, for example, about 20 ° from the tip of the bending piece 21 and has a radius of about 3.2 cm with respect to the above-described radius of 3 cm of the band pieces 2a and 2b. In the large-diameter portion 25, a diameter of about 2 mm is enlarged.

  By arranging the large-diameter portion 25, the band piece 2a for temporarily placing the pipe is 220 ° from the lower end of the suspension piece 22 to the tip of the connection free end 3 except for the gap between the suspension pieces 22 and the connection free end 190. By having a bending angle exceeding 180 °, which is equal to the outer diameter of the pipe 6, the opening becomes smaller than the outer diameter of the pipe 6. The opening 6 can be enlarged so as to have a width substantially equal to the outer diameter or slightly smaller than the outer diameter. For example, the temporary placement of the pipe 6 can be performed without being pressed against the elasticity of the band piece 2a. By using the own weight of the pipe 6 and placing it on the band piece 2a for temporarily placing the pipe, or by pressing it a little from the top after that, it is possible to carry out the process smoothly and smoothly.

  At this time, in this example, the disposition of the tip overlapping piece 33 at the connection free end 3 is further arranged so as to leave a gap of about 1 mm with respect to the inner diameter of the band piece 2a. In addition, since the opening at the lower end of the suspension piece 22 and the tip of the free connecting end 3 is enlarged by about 3 mm in total with respect to the pipe 6, the opening reduced by the bending angle is connected to the pipe 6. Therefore, in this example, the temporary placement of the pipe 6 can be further simplified by placing the pipe 6 on the opening due to the contribution of the gap. It can be carried out.

  In addition, since the large-diameter portion 25 is arranged, the lower end position of the hanging piece 22 of the band piece 2b for holding the pipe moves upward by about 2 mm on the tangle 1 side. By arranging a space for avoiding a collision with the pipe 6 temporarily placed on the band piece 2a for temporary placement of the pipe, the track is separated to the outside, and the bolt of the band piece 2b for holding the pipe Even if the standing width from the outer side 4a to the outer side is reduced, the band piece 2b can be prevented from coming into contact with the upper portion of the pipe 6. Therefore, the nut 4b necessary for raising the band piece 2b to the outer side. The loosening width can be minimized. Moreover, in this example, since the bolt insertion hole 23 arranged in the hanging piece 22 of the band piece 2b is an upper and lower elongated hole, the elongated hole contributes to standing outside the band piece 2b. It is possible to further minimize the loosening width of the nut 4b and the tightening width of the tightening back during the piping operation.

  In the pipe suspension band A of the present example formed as described above, the connection free ends 3 of the band pieces 2a and 2b are mutually connected, and the suspension piece 22 of the tangle 1 and the band pieces 2a and 2b is temporarily placed in the pipe. The bolt head of the bolt 4a is arranged on the side of the hanging piece 22 in the band piece 2a for use, and the nut 4b is arranged on the side of the hanging piece 22 in the band piece 2b for holding the pipe. At the same time, the turnbuckle 1 is arranged so as to be rotationally housed inside the pipe suspension band A, and is carried in and used on site in the form of a band piece integrated shipping form. The piping work at the site is performed by rotating the tumbler 1 to the outside of the piping suspending band A to escape, and screwing the rotating nut 11 of the tumbler 1 to a suspension bolt (not shown), thereby forming a plurality of suspension bolts. On the other hand, after the plurality of pipe suspension bands A are suspended and supported, the nuts 4b of the bolt nuts 4a and 4b are slightly loosened, and the band piece 2b for pipe holding is rotated about the bolt 4a as a rotation axis. 2a and 2b, the connection free end 3 is released, and the band piece 2b for holding the pipe is separated from the band piece 2a for temporarily placing the pipe, and each of the plurality of pipe suspension bands A is temporarily placed on the pipe. The pipe 6 is temporarily placed so as to be installed over the piece 2a, and then the band piece 2b for holding the pipe is placed in the outer circumferential direction of the pipe with the bolt 4a as a rotation shaft so that the pipe 6 is fitted and supported. Rotate and connect free end 3 on both sides In the connected state of the connection free end 3, the nut 4a located on the hanging piece 22 side of the band piece 2b for holding the pipe is tightened back, and the fastening with the bolt nuts 4a and 4b is performed. At this time, the connection free end 3 is connected by superimposing the tip overlap pieces 33 on the step overlap pieces 31 of both the band pieces 2a and 2b and engaging both the notch grooves 32, and the cut and raised projections 35. This is done by engaging the step overlap piece 31 and the tip overlap piece 33 of the other band piece 2a or 2b in a hooked manner.

  At this time, the pipe suspension band A of the present example can simplify the temporary placement of the pipe 6 on the band piece 2a as much as possible by the large diameter portion 25 of the band piece 2a for temporary placement of the pipe. In addition, the temporary placement and placement can be performed stably, and the loosening width of the nut 4b and the tightening width of the tightening can be reduced by the large diameter portion 25 of the band piece 2b for holding the pipe. Therefore, the work efficiency of the piping work can be as high as possible.

  In the figure, reference numeral 12 denotes a nut retaining member for preventing the rotary nut 11 from dropping, 24 denotes a rotation stop of the bolt 4a of the suspension piece 22, and 26 denotes reinforcing ribs of the band pieces 2a and 2b.

  The example shown in the figure is as described above, but the tan buckle is formed integrally with the hanging piece of the band piece for temporary piping placement, that is, the supporting piece of the tun buckle and the hanging piece are integrated to integrate both. One of the band piece for temporary placement of the pipe suspension band or the band piece for pipe holding of the pipe suspension band is set to have a diameter larger than the inner diameter of the band piece near the suspension piece in the bending direction. This includes placing a concentric large diameter part up to the standing position of the upper end of the hanging piece to facilitate the temporary placement of the pipe or reducing the loosening width of the nut and the tightening width of the tightening. In carrying out the invention, the specific shape, structure, material, etc. of the pipe suspension band, the band piece for temporary placement of the pipe, the band piece for the pipe retainer, the large-diameter portion, the tangle, the suspension piece, the bolt hole, etc. The relationship of the above, addition to these, etc. are the gist of the above invention It can be of various forms as long as it is not contrary.
