Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pipe pillow for supporting a pipe such as a cable protection pipe. In particular, the present invention relates to a pipe pillow in which a power cable or a communication cable can be applied to a free access conduit in a common wire groove B as shown in FIG. In FIG. 9, 1, 1A is a tube pillow, 2, 2A is a tube pillow main body, 3 is a semicircular tube receiving portion, and 8, 8A are cable protection tubes.

[0002]

2. Description of the Related Art When a pipeline is branched in a conventional cable common groove, a special portion such as a handhole or a manhole is provided between multiple multistage pipelines. The pipeline configuration is usually arranged in multiple rows and multiple stages using a pipe pillow. As this tube pillow, for example, Japanese Utility Model Laid-Open No. 2-132189

[0033]

According to the first to third aspects of the present invention, since the bottom heights of the plurality of pipe receiving recesses are sequentially increased from one side of the pipe pillow body to the other side, each cable pipe is provided with a different height. Each cable channel can be supported by a pipe pillow in a state where the pipe axis of the channel is shifted upward (or downward) by the difference in the bottom height of the tube receiving recess. For this reason, branch pipe joints for cable entry can be installed on the outer surface of each cable conduit without interfering with each other without providing special parts such as handholes, and it is easy to draw each cable through this branch pipe joint. It can be carried out.

In the present invention, the pipe pillow main body is constituted by a plurality of pipe pillow members having one pipe receiving recess on the upper surface and having different bottom heights of the pipe receiving recesses. Therefore, various types of multi-row tube pillows can be obtained by combining the respective tube pillow members.

Further, according to the third aspect of the present invention, various types of multi-row pipe pillows are obtained by disposing a spacer member having a predetermined thickness in the pipe receiving recess of the integrally formed multi-row type pipe pillow body. be able to.

According to the present invention, the pipe pillow body is
An adjacent pipe pillow member is constituted by a plurality of pipe pillow members provided with one pipe receiving concave portion on the upper surface and having a fitting convex portion or a fitting concave portion provided on both side surfaces along a vertical direction. The fitting projections and the fitting recesses are slidably fitted in the vertical direction, and a spacer member is disposed on the upper surface or the lower surface of the other tube pillow member excluding the tube pillow member on one side. Since the bottom heights of the recesses are substantially sequentially increased from one side to the other side, the pipe shaft of each cable conduit supported by the pipe receiving recess of each pipe pillow member is raised by the spacer member. Each cable conduit can be supported by the pipe pillow member in a state shifted upward (or downward) by a distance. For this reason,
A branch saddle joint for drawing in a cable can be installed on the outer surface of each cable conduit without interfering with each other without providing a special portion, and each cable can be easily drawn through the branch saddle joint.
