Abstract

PROBLEM TO BE SOLVED: To positively prevent the dislocation of connection parts of a pipe body is a suspended state by disposing dislocation preventive member crossing the connection parts of the pipe body along the axial direction of the pipe body on the outer peripheral surface of the pipe body in the structure of suspending the pipe body formed by connecting a plurality of pipe bodies, by suspension members. SOLUTION: In excavating work, a pipe body 1 such as a water pipe is supported in the state of being suspended in the air until backfilling. At the time of executing suspension work of the pipe body 1, supports 2 are erected at specified spaces on both sides of the pipe body 1, and a cross beam 3 is laid between the upper end parts of the respective supports 2. A stringer 4 is then laid on the upper part of the cross beam 3 along the whole length of the pipe body 1. A dislocation preventive member 5 is fitted crossing each connection part 11 of the pipe body 1 in the axial direction of the outer peripheral surface of the pipe body 1. The dislocation preventive member 5 and the pipe body 1 are fastened by fastening bands 6. The required number of suspension belts 8 with suspension members connected to both ends are wound around the pipe body 1 from the bottom part side, and the free end of each suspension member 7 is fixed to the stringer 4 by a bolt or the like to complete suspension support structure of the pipe body 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for suspending a tubular body.

[0002]

2. Description of the Related Art As shown in FIG. 2, a suspended structure in which a pipe a is suspended by a suspending member b and supported by a vertical girder c and a horizontal girder d before excavating an underground buried pipe in excavation work. Has been adopted.

[0003]

In the above prior art, when the pipe is made of ductile cast iron pipe or the like, the connecting portion e may be displaced due to shaking before being refilled. It may cause damage.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a suspension structure of a pipe which can prevent displacement of a connecting portion of the pipe in a suspended state. The purpose is to:

[0005]

Means for Solving the Problems As means for solving the above-mentioned problems, in a structure in which a plurality of pipes are connected by a hanging material, a pipe is connected to an outer peripheral surface of the pipe. A suspension structure for a tubular body, characterized in that a slip prevention member is disposed along the axial direction of the tubular body so as to cross the portion. Hereinafter, an embodiment of the present invention will be described with reference to FIG.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION

<B> Suspension Structure As shown in FIG. 1, in excavation work, since the pipe 1 buried underground such as a water pipe is exposed, it is supported in a suspended state until it is backfilled. You. The suspension structure of the tube 1 is constructed in the following procedure.

When the pipe 1 is exposed by the excavation work, the pillars 2 are provided on both sides thereof.
Are erected at predetermined intervals. It is conceivable that the strut 2 is formed by casting H steel or the like.

Next, a cross beam 3 of H steel or the like is erected between the upper ends of the columns 2 and in a direction perpendicular to the upper side of the tube 1. The required number of the cross beams 3 are provided at predetermined intervals over the entire length of the tubular body 1.

Construction of the vertical girder When the construction of the horizontal girder 3 is completed, a vertical girder 4 made of H-steel and a plate is erected above them along the entire length of the tubular body 1.

The rubber sheet is wound around the tube 1 by connecting a plurality of single tubes at a connecting portion 11. Before hanging and supporting the rubber sheet, it is preferable to wind a rubber sheet for protection (not shown). .

After the rubber sheet is wound, the slip preventing member 5 is attached across the connecting portions 11 of the tube 1 in the axial direction of the outer peripheral surface of the tube 1. The slip prevention member 5 serves as a splint of the tubular body 1, and the shape and the material are not particularly limited as long as the connecting portion 11 of the tubular body 1 has a strength capable of preventing occurrence of a shift due to shaking or the like. .

FIG. 1 shows a case in which an L-shaped angle steel material is used, and when it is attached to the tube 1, both edges are in contact with the outer peripheral surface of the tube 1, and the corners are separated from the tube 1. Attach. Further, as a method of fixing the slip prevention member 5 and the tube 1, a method of fastening a stop band 6 such as a steel band at a predetermined interval can be considered.

The slip preventing member 5 may be attached to one piece over the entire length of the tubular body 1 or may be attached to a plurality of pieces at predetermined intervals in the axial direction. Also in the case of separately mounting a plurality of pipes, the mounting is performed such that each slip prevention member 5 crosses each connecting portion 11 of the tubular body 1.

If the entire length of the tubular body 1 is to be fixed by one, and if the overall length is long, a plurality of slip prevention members 5 are connected to each other by connecting metal fittings 51 to form a desired length.

The slip preventing member 5 can be attached not only to the upper portion of the tube 1 as shown in FIG. 1, but also to a side portion or a bottom portion other than the upper portion. Further, it is conceivable to attach a plurality of tubes 1 at predetermined intervals in the circumferential direction of the tube 1.

After attaching the suspension member 5 for preventing the suspension from being suspended by the suspension member, a required number of suspension belts 8 having suspension members 7 such as steel bars connected to both ends are wound around from the bottom side of the tube 1. Then, the free end of each suspending member 7 is fixed to the vertical girder 4 with bolts or the like to complete the suspending support structure of the tube 1.

[0017]

As described above, according to the present invention, since the slip preventing member is disposed in the axial direction across the connecting portion of the pipe, the slip preventing member serves as a splint, and the pipe in a suspended state is provided. The displacement of the connecting portion can be prevented, and the cause of water leakage and breakage can be eliminated.
