Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe connecting method for directly connecting a pipe and another pipe and fixing the pipe and its structure.

[0002]

2. Description of the Related Art Conventionally, golf practice has been practiced in a golf driving range in which a ball structure is lined around a frame structure. Here, the frame structure is usually composed of a plurality of columns that are erected on the ground and a beam that is passed over the plurality of columns. These columns and beams are configured by connecting a plurality of pipes so that they can be easily transported during construction.

In this tube connecting method, as shown in FIG. 5, first, a flange 2 provided at one end of a tube 1 and a flange 4 provided at one end of another tube 3 are matched. With the flanges 2 and 4 aligned, the bolt 5
Is inserted into the hole 6 of the flange 2 and the hole 7 of the flange 4, and the nut 8 is fastened. In this manner, the flanges 2 and 4 are aligned and fixed by the bolt 5, so that one end of the pipe body 1 and one end of the other pipe body 3 are connected and fixed.

[0004]

However, according to such a pipe connecting method, it is necessary to match the flanges 2 and 4, so that pipes other than those having the same size flange can be connected. There wasn't. Therefore, it was not possible to freely select the pipe to be connected. Further, the flanges 2 and 4 protruded from the connecting portion to the surroundings, which became an obstacle to the ball-proof net to be stretched. For this reason, it is impossible to raise and lower the ball-proof net smoothly during a typhoon, and the ball-proof net may be broken when the ball-proof net is moved up and down. Furthermore, if only the flanges 2 and 4 are projected to the periphery, it is not preferable in appearance. Therefore, it has been a cause of impairing the aesthetics of the driving range. Further, in order to connect the tubes by such a method, it was necessary to process and manufacture the flange in advance and then fix the flange to one end of the tube. For this reason, a lot of time and labor is required for processing work and the manufacturing unit price becomes expensive.

Therefore, the present inventor has accomplished the present invention as a result of extensive research to provide a tube connecting method and its structure capable of solving the above problems.

[0006]

The gist of the pipe connecting method of the present invention is that a part of the other end of another pipe is inserted into one end of the pipe to connect and fix it straight. In the pipe connecting method described above, after disposing a contact member inside a predetermined position from an opening on one end side of the pipe, the other end of the other pipe is inserted into one end of the pipe. Then, the contact member is brought into contact with the corresponding contact member, and then the solidifying material is filled and fixed in a gap between the pipe member and another inserted pipe member.

In such a pipe connecting method, a partition plate for covering at least a gap between the pipe and another inserted pipe is arranged on the contact member side.

Further, in this pipe connecting method, the partition plate provided inside the pipe is engaged with the other end of another pipe inserted into the pipe, The body and other tubes are to be positioned.

Further, in this pipe connecting method, wedges formed with a slope are driven into a plurality of gaps formed between the pipe and other inserted pipes, and the wedges are connected to each other. After adjusting the straightness with other pipes, the gap is filled with a solidifying material.

Further, in such a pipe connecting method, the wedge driven into the gap is solidified by the solidifying material, then removed from the gap, and then the gap is filled with the solidifying material to solidify.

Next, the gist of the pipe connecting structure according to the present invention is that the contact member is disposed at a predetermined internal position from the opening on the one end side of the pipe, and the other contact member is Is inserted into the tubular body so that the other end of the tubular body is brought into contact with the tubular body, and the solidifying agent is further filled and solidified in the gap between the tubular body and the other tubular body to It is to be connected to the pipe body.

[0012]

According to the pipe connecting method of the present invention, first, the abutting member is arranged inside the predetermined position from the opening on the one end side of the pipe,
Another tubular body connected to the tubular body is inserted into the hollow portion of the tubular body to bring the end portion of the other tubular body into contact with the contact member. As a result, the tubular body and the other inserted tubular body are positioned, and the total length of the connected tubular body and the other tubular body is accurately determined. On the other hand, a gap is formed between the outer circumference of another tubular body inserted in the hollow portion of the tubular body.

Next, the other tubular body is held so as to be straight with respect to the tubular body, and the solidifying material is poured into the gap from the opening at one end and filled in the gap. The solidified material is solidified under certain conditions while the solidified material is filled in the gap. By solidifying the solidifying material, the outer periphery of the one end of the other tubular body is fixed in the hollow portion of the tubular body. In this way, the solidifying material is filled in the gap and solidified, so that the tubular body and the other tubular body are directly connected and fixed.

Further, in the pipe connecting method of the present invention in which the partition plate covering substantially the entire ring cutting surface of the gap is superposed on the abutting member, the partition plate covers substantially the entire ring cutting surface of the gap. The solidifying material is poured into the gap and filled. Since the partition plate covers almost the entire ring cut surface of the gap, the solidified material does not enter into the back of the partition plate. Since the solidifying material does not go deeper than the partition plate, the solidifying material is liquid-tightly filled in the gap.

Further, in the pipe connecting method of the present invention in which a wedge, which is thicker at one end and becomes thinner toward the other end, is driven into the gap, and then the solidifying material is filled in the gap, the wedge is a ring cut surface of the pipe. By driving a plurality of pipes in the same direction, other pipes are adjusted and held so as to be straight with respect to the pipes. Here, when the other tubular body is not straight with respect to the tubular body, the driving depths of the wedges are respectively adjusted so that the other tubular body is straightened with respect to the tubular body. Next, the solidifying material is solidified, and the tubular body and the other tubular body are directly connected and fixed. When one end of the wedge protrudes from the solidified material, the wedge driven into the gap is pulled out to adjust the appearance. Here, as the wedge is pulled out, a trace of the wedge pulled out of the solidified material remains in a concave shape, so that the solidified material is further replenished in the concave shaped trace. The solidified material is further replenished in the concave-shaped traces and solidified under a certain condition, so that a fine finish is obtained.

Further, the pipe connecting method of the present invention is such that one end of another pipe is inserted into one end opening of the pipe and brought into contact with the contact member while being meshed with the contact member. The other tube is fixed to the contact member such that one end of the tube is meshed with the contact member. Since the other tube is fixed to the abutting member by engaging one end of the other tube with the abutting member, even if the adhesive force of the solidifying material is weak, the twisting force or the rotating force may be applied. Other pipes will not be separated from the solidified material.

Further, one end of another pipe is inserted into one end of the pipe, and a solidifying material which is solidified under a certain condition is filled in a gap between the pipe and the other pipe so that the pipe and the other pipe are not filled with each other. Is a pipe connection structure for connecting and fixing the pipe in a straight line, and an abutting member that is fixed by being bridged in the ring cutting surface direction of the hollow part of the pipe is provided near the opening at one end of the pipe. In the provided pipe connecting structure of the present invention, one end of the other pipe inserted into the hollow portion from the one end opening is stopped by the contact member and brought into contact with the contact member. Next, the solidifying material is poured into and filled in the gap between the tubular body and the other tubular body, and the solidifying material is solidified under certain conditions. By solidifying the solidifying material, the tubular body and the other tubular body are directly connected and fixed.

Further, since the partition plate that covers substantially the entire ring cutting surface of the gap is provided in the vicinity of the abutting member so as to be superposed, the partition plate covers substantially the entire ring cutting surface of the gap. The solidifying material is poured into the gap and filled. Since the partition plate covers almost the entire ring cutting surface of the gap, the solidifying material does not enter the interior of the partition plate and the solidifying material is liquid-tightly filled in the gap.

The other tube body 14 is fixed to the stopper 20 by engaging the engagement groove 40 with the rod-shaped members 24 and 26 of the stopper 20. Therefore, even if the adhesive force of the mortar 34 is weak, the other tube body 14 is not separated from the mortar 34 by the external force such as the twisting force or the rotating force.

Further, as shown in FIG. 3, a disc (partition plate) 42 may be superposed on the stopper 20 provided on the pipe body 12. After the disc 42 is superposed on the stopper 20, one end of the other pipe body 14 is inserted and brought into contact with the disc 42, whereby the mortar 34 to be filled in the gap 32 between the pipe bodies 12 and 14 is formed into the pipe body. It doesn't go all the way into 12. Therefore, even if the partition plate 22 is not provided at one end of the other pipe body 14, it is possible to prevent the mortar 34 from entering the interior of the pipe body 12. A cross-shaped groove may be provided on the back surface of the disk 42, and the groove may be engaged with the stopper 20 to prevent the disk 42 from rotating.

Further, as shown in FIG. 4, a reinforcing metal fitting 44 may be built in the mortar 34. As shown in FIG. 4A, the reinforcing metal fittings 44 are placed in the hollow portion 16 of the pipe body 12 so that two reinforcing metal fittings 44 are placed on the stopper 20 in a cross shape. Next, after one end of the other tubular body 14 is inserted, as shown in FIG. 4B, the mortar 34 is filled in the gap 32 and solidified. According to such a pipe connecting method, since the mortar 34 is reinforced by the reinforcing metal fitting 44, it is possible to prevent the mortar 34 from being crushed by applying an external force to the pipe 12 or 14. Therefore, the tubular body 12 can be stably fixed to the other tubular body 14. In this embodiment, when the strength of the reinforcing metal fitting 44 is sufficient, the stopper 20 is not always necessary, and the reinforcing metal fitting 44 can function as a stopper, that is, a contact member.

With a wedge that is entirely embedded with such a solidifying material, it is not necessary to finish the concave portion that occurs when the wedge is removed. Further, it may be a wedge in which the other end portion inserted into the gap is made long.
With a wedge whose other end inserted into such a gap is long, another tube can be firmly held and fixed. In addition, other shapes may be used as long as the wedge is thicker at one end and thinner toward the other end and can be driven into the gap between the tubular body and the other tubular body from the other end. Further, the number and position of the wedges to be driven into the gap are not particularly limited, and it is sufficient that other pipes can be held upright with respect to the pipes.

The solidifying material is not limited to the above mortar, but may be an adhesive or other resin, or
It may be a liquid agent that is solidified by mixing with another liquid agent. Further, the solidifying material may be made of foam.

Further, the shape of the contact member is not particularly limited,
What is necessary is just to be able to stop one end of the other pipe inserted into the one end opening of the pipe. In addition, the present invention can be carried out in a mode in which various improvements, modifications and variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
