Description

  The present invention relates to a piping support for piping a long pipe supported by a structure at a predetermined interval.

  Conventional pipe supports include an upper holder and a lower holder that hold the pipe from above and below, a bracket that horizontally supports the lower holder with respect to the structure, the bracket, the lower holder, and the upper holder. It is generally configured by bolts and nuts that integrally connect the tools (see, for example, Patent Documents 1 and 2).

  By the way, in the above technique, when vibration occurs due to an earthquake or the like, the tube is firmly fixed firmly in close contact with the upper and lower receivers. The stress was separately applied to the supporting position of the tube, and the durability of the tube was lowered. In addition, when installing the pipe, the installation position is finely adjusted by sliding the pipe on the support, but if the pipe is made of heavy material such as cast iron, it is difficult to move due to friction, and workability is improved. It was bad.

  The problem to be solved by the present invention is to solve these conventional problems and to improve the durability of the tube and the installation workability of the tube during vibration.

The configuration of the present invention that solves this problem is as follows.
1) In a pipe support that pipes a long pipe supported by a structure at a predetermined interval, an upper holder and a lower holder that hold the pipe from above and below, and the lower holder with respect to the structure It comprises a bracket that is supported horizontally, and bolts and nuts that connect the bracket, the lower receiver, and the upper receiver, and a belt-shaped tube receiving portion that contacts the outer surface of the pipe on the inner surface of the lower receiver and the upper receiver. Projecting, forming a sliding layer with low frictional resistance on the surface of the tube receiving part, and holding the tube, the upper receiver and the lower receiver are brought into close contact with each other and tightened with bolts and nuts. The pipe support 2 is characterized in that a gap of 1 mm or more is formed between the inner surface of the tube receiving portion and the outer surface of the tube. The sliding layer is formed by baking the fluororesin to a thickness of 10 to 30 μm. The piping support 3) described in 1) above is formed, and the width of the tube receiving portion of the upper support and the lower support is supported. The pipe support 4) according to the above 1) or 2), which is formed in the range of 6 to 30% of the outer diameter of the pipe to be obtained, and the slip receiving layer is formed on the pipe receiver of the lower receiver The pipe support tool according to any one of 1) to 3), wherein the pipe support is formed to have a substantially trapezoidal cross section inclined downward in the width direction from the surface.

  According to the present invention, even when the pipe support vibrates violently due to an earthquake or the like, the gap between the upper support and the pipe becomes a buffer layer, and stress is not easily applied to the plurality of support positions of the pipe separately. The durability of the tube can be maintained. Further, when installing a heavy pipe, fine adjustment is facilitated by the sliding layer formed in the pipe receiving portion, and workability is improved. Further, the outer surface of the tube is not easily damaged by the slip, and the durability of the tube is not lowered.

It is a front view of the support tool for piping of an Example. FIG. 2 is a cross-sectional view taken along line A-A ′ of FIG. 1. FIG. 2 is a sectional view taken along line B-B ′ of FIG. 1. It is explanatory drawing which shows the isolation | separation state of the support tool for piping of an Example. It is a longitudinal cross-sectional view of the support for piping of the other example of an Example.

  As the sliding layer of the present invention, a fluororesin having a low frictional resistance and excellent weather resistance is selected, and the thickness of the sliding layer is practically in the range of 10 to 30 μm. If it is 10 μm or less, the slipperiness is insufficient, and if it is 30 μm or more, the cost is high.

  The width of the tube receiving portion is preferably in the range of 6 to 30% of the outer diameter of the tube to be supported so that the outer surface of the tube can be received by the surface and the load can be distributed and the durability can be maintained. If it is less than 6%, it may reduce the durability due to concentrated load on the local area of the outer surface of the pipe, and if it is more than 30%, it becomes difficult to bend when the pipe is curved, and the pipe support is more than necessary. Increase in size.

  As the shape of the tube receiving portion of the lower receiving device, when it is inclined downward in the width direction from the surface on which the sliding layer is formed and formed into a substantially trapezoidal cross section, the edge of the tube receiving portion does not protrude due to the inclination, For example, when a slightly soft pipe such as a polyethylene pipe or a vinyl chloride pipe is installed, the outer surface of the pipe is hardly damaged. Moreover, you may form the pipe | tube receiving part of an upper receiver also in cross-sectional substantially trapezoid shape.

  Examples of the material for the pipe support include metal and FRP (fiber reinforced plastic), which are selected according to the material and strength of the pipe to be installed. The tube receiving part may be formed integrally with the same material as the upper and lower receivers, or a separate member made of a different material may be attached. For example, an FRP tube receiving portion may be fixed to a metal upper receiver and lower receiver.

  Embodiments of the present invention will be specifically described below with reference to the drawings. The embodiment shown in FIGS. 1 to 4 is an example of a pipe support for piping a pipe made of ductile cast iron having a pipe outer diameter of 118 mm on the wall of a structure. 1 is a front view of a pipe support of the embodiment, FIG. 2 is a cross-sectional view taken along the line AA ′ of FIG. 1, FIG. 3 is a cross-sectional view taken along the line BB ′ of FIG. It is explanatory drawing which shows the isolation | separation state of a support tool.

  In the figure, 1 is a pipe support, 2 is a lower support, 2a is a pipe receiving part, 2b is a sliding layer, 2c is a bolt hole, 3 is an upper receiving part, 3a is a pipe receiving part, 3b is a sliding layer, 3c Is a bolt hole, 4 is a bolt, 5 is a nut, 6 is a bracket, 6a and 6b are bolt holes, 7 is an anchor bolt, 8 is a nut, A is a water pipe, and B is a wall of the structure.

  The lower support 2 is made of cast iron and is substantially U-shaped. A strip-shaped tube receiving portion 2a having a thickness of 5 mm is projected on the inner surface thereof, and a fluororesin is baked on the surface of the tube receiving portion 2a to a thickness of 20 μm. The sliding layer 2b is formed. Bolt holes 2c for passing bolts 4 are machined in the left and right horizontal plate portions. The width of the tube receiver 2a is 18 mm. The lateral width of the lower support 2 is 260 mm and the depth is 65 mm.

  The upper support 3 is made of cast iron in an inverted U-shape, and a strip-shaped tube receiving portion 3a having a thickness of 5 mm is projected on the inner surface thereof, and a fluororesin is baked on the surface of the tube receiving portion 3a to a thickness of 20 μm. The sliding layer 3b is formed. Bolt holes 3c for passing bolts 4 are machined in the left and right horizontal plate portions. Further, when holding the water pipe A and connecting the upper receiver 3 and the lower receiver 2 in close contact with each other with the bolt 4 and the nut 5, 1 mm is provided between the inner surface of the pipe receiver 3 a and the outer surface of the water pipe A. The size is such that a gap h can be formed. The width of the tube receiving portion 3a is 18 mm. The left and right width of the upper support 3 is 260 mm, the depth is 65 mm, and the height is 150 mm.

  The bracket 6 is made of cast iron in an L-shape, and the horizontal plate portion is formed with bolt holes 6a for passing the bolts 4 to the left and right, and the vertical plate portion is provided with bolt holes 6b for passing the anchor bolts 7 up and down. It is processed into.

In this embodiment, attachment is performed as follows.
1) The vertical plate portion is brought into close contact with the wall B of the structure through the bolt hole 6b of the bracket 6 to the anchor bolt 7 of the wall B of the structure and double-tightened with the nut 8.
2) The lower receptacle 2 is arranged on the horizontal plate portion of the bracket 6, and the water pipe A is arranged on the pipe receiving portion 2 a of the lower receptacle 2.
