Abstract

PROBLEM TO BE SOLVED: To prevent pipes connected with each other in parallel from slipping or coming out by arranging a plurality of pipe pillow units each of which is formed with a pipe receiving part in its upper surface, in parallel in the direction normal to the axial line direction of each pipe receiving part, and connecting the opposite peripheral sides of the bottom surfaces of each pipe unit by a hinge. SOLUTION: When pipeline groups such as cable pipes 5 and the like are buried underground, the pipe pillow 1 for supporting and disposing the pipe-line groups, is composed of two pipe pillow units 2 and 3, and one pipe pillow unit 2 and the other pipe pillow unit 3 are connected in parallel by a hinge 4. Each pipe pillow unit 2 and 3 is formed with each pipe receiving part 21 and 31 in a semi-circular shape on which the cable pipe 5 is rested at its center, besides, the hinge 4 is provided for the opposite peripheral sides of the bottom parts for the pipe pillow units 2 and 3 in such a way as to be integrally formed therewith, so that this constitution thereby allows the pipe pillow units 2 and 3 to be connected with each other in such a way as to be freely flexed. The cable pipes 5 can thereby be disposed horizontally or verticaly by arranging the pipe pillow units 2 and 3 in parallel in the horizontal direction or the vertical direction.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe pillow for supporting and arranging a group of pipes such as an electrolytic tube.

[0002]

2. Description of the Related Art Conventionally, a plurality of conduits have been made parallel to each other when burying underground electric tubes or the like. A tube pillow as described in JP-A-132189 is known. This tube pillow can be connected in parallel in the horizontal direction or the vertical direction as appropriate according to the number of electrolytic tubes or the like and the conditions of the embedding place.

[0003]

However, in the connecting portion of the tube pillow described in the above-mentioned publication, the fitting convex portion formed on the other tube pillow is fitted into the fitting concave portion formed on one tube pillow. It engages and connects a plurality of pipe pillows in parallel, and at the same time, engages and locks the connection pin in the gap hole provided in the joint surface between the fitting concave portion and the fitting convex portion. , The connected pipe pillows do not come off or come off,
The structure of the connecting part becomes complicated, it takes time for construction,
There is a problem that the cost of manufacturing a tube pillow is expensive.

SUMMARY OF THE INVENTION [0004] The present invention has been made to solve the above-mentioned problems in the prior art, and an object of the present invention is to make it possible for pipe pillows connected in parallel to be displaced or disconnected. Another object of the present invention is to provide a tube pillow that is easy to construct at the same time and can be manufactured at low cost.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object. According to the first aspect of the present invention, a plurality of tube pillow units having a tube receiving portion formed on an upper surface are provided. The pipe pillows are arranged in parallel in the direction perpendicular to the axis of the pipe receiving portion, and opposite edges of the bottom surfaces of adjacent pipe pillow units are connected by hinges.

In the tube pillow of the present invention, the tube pillow unit may be connected by a separate hinge (for example, a metal hinge). However, a joint bearing portion of the tube pillow unit and the hinge is integrally formed. The pipe pillow unit may be connected by inserting a connecting shaft into the connecting bearing to form a hinge. Alternatively, when the hinge is formed of a thin piece of a flexible synthetic resin, and this hinge is formed integrally with each pipe pillow unit, the structure is simplified and the number of parts can be reduced. .

In the tube pillow according to the first aspect, the opposite edges of the bottom surfaces of adjacent tube pillow units are connected by hinges, so that the tube pillow units do not shift or come off. In addition, since there is no need for a troublesome connecting operation such as inserting a connecting pin after connecting the fitting portions as in the case of a conventional pipe pillow, the construction is simple and the manufacturing can be performed at low cost. In particular, if the hinge is formed integrally with the tube pillow unit, it can be manufactured at lower cost.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. FIG. 1 is a perspective view of a tube pillow, FIG. 2 shows a use state of the tube pillow of FIG. 1, and FIG. Sectional drawing of the tube pillows arranged in parallel, (b) is a sectional view of the tube pillows arranged in parallel in the vertical direction. 1 and 2, 1 is a tube pillow, 2 and 3 are tube pillow units, 21 and 31 are tube receiving portions,
4 is a hinge and 5 is an electric tube.

The pipe pillow 1 according to the present invention is made of, for example, a synthetic resin such as polyethylene or polypropylene. As shown in FIG.
3, one tube pillow unit 2 and the other tube pillow unit are connected in parallel by a hinge 4. The above-mentioned tube pillow units 2 and 3 are formed with semicircular tube receiving portions 21 and 31, respectively, in which the electrolytic tube 5 is provided at the center of the upper surface. Further, the hinge 4 is formed of a thin semicircular sheet piece, and is integrally formed on the opposite edge of the bottom of the tube pillow units 2 and 3 so that the respective tube pillow units 2 and 3 can be bent freely. Connected.

In the method of using the above-mentioned tube pillow 1, FIG.
As shown in (a), when the tube pillow units 2 and 3 are arranged in parallel in the horizontal direction, the electric tubes 5 can be arranged in parallel in the respective tube receiving portions 21 and 31 in the horizontal direction. FIG.
(B) As shown in FIG.
Can be positioned up and down. Furthermore, when the hinge 4 is cut, the tube pillow units 2 and 3 can also be used as a single tube pillow.

[0010]

According to the pipe pillow of the present invention, since the pipe pillow units are connected in parallel by hinges, the pipe pillows can be used in both a horizontal parallel arrangement and a vertical parallel arrangement. Can also be used as a tube pillow. Therefore, since one pipe pillow can be deployed in various arrangements, the number of parts can be reduced.

Further, in the tube pillow of the present invention, the tube pillow units do not shift or come off from each other, and the connecting pins are inserted after connecting the fitting portions as in a conventional tube pillow. Since no complicated connection work is required, the construction is simple, and since there is no fitting portion, the structure is simple and the production can be performed at low cost.
