Description

The present invention relates to an outdoor column used as a column for standing in an outdoor field, for example, a rugby goal, a volleyball column, a tennis column, and a ball-proof net. The present invention relates to a plug-and-support column composed of a main body.

Technology background

The pull-out type props erected on an outdoor field are intended for multi-purpose use of the field, and include rugby goals, volleyball posts, tennis posts, and a pole for attaching a ball for netting.

The rugby goal is composed of two buried pipes buried in the ground and a substantially H-shaped pillar body that stands on the ground by inserting a lower end into a hole provided in each buried pipe and fixing with a stopper. The volleyball strut is composed of a buried pipe buried in the ground and a pillar main body standing upright on the ground by inserting a lower end portion into a hole provided in the buried pipe and fixing with a stopper. The fence post for the ball-proof net provided along the outer periphery is erected by inserting a plurality of buried pipes buried in the ground and fixing the lower end portion into a hole provided in the buried pipe with a rod-shaped stopper. It consists of a pillar body.

The problem of sand clogging has been solved by using rib-structured aluminum pipes because sand and pebbles are not allowed to flow into the holes of the buried pipes of the columns.

Problems to be solved by the invention

However, since the diameter of the hole in the buried pipe of the above-mentioned conventional outdoor column is only slightly larger than the diameter of the column body, the column body always stands upright in the hole of the buried tube when inserted. There is a drawback that requires the use of heavy machinery and the labor of many workers.

In addition, there is a drawback that the inflow of sand or the like into the hole cannot be prevented with the rib structure alone, and when inserting the column body into the hole, it is necessary to remove the sand that has flowed in. There was a defect that sand entered even when inserted.

Therefore, the present invention is to provide a column-type support column that can smoothly insert the column main body into the buried pipe, has excellent workability at the time of the plug-in operation, and can prevent inflow into a hole such as sand. Let it be an issue.

Means for solving the problem

In order to solve the above-mentioned problems, the present invention is used for outdoor ball games and the like as described in claim 1 and is buried in the ground and formed with a hole, and inserted into the hole of the buried pipe A column main body, and a column- type strut formed on the column main body and configured to stop the insertion into the hole of the buried pipe at a desired position, and a cross-sectional portion of the hole of the buried pipe By increasing the thickness, a tapered portion that is the same as the diameter of the buried tube and extends upward is provided on the upper end side of the buried tube, and the lower end side of the column body is formed in a hemispherical shape so as to be inserted into the hole along the tapered portion. The diameter of the column main body is larger than that of the stopper portion that stops the insertion into the hole of the buried pipe .

Effects and effects of the invention

Next, the function and effect of the pull-out type column of the present invention will be described.

First, a hole is drilled in the ground and a buried pipe is buried in the ground. At this time, the upper end side of the hole of the buried pipe is provided with a tapered portion that extends upward, so that the diameter of the hole can be expanded and expanded from the insertion portion.

Next, the lower end side of the column main body is inserted into the buried pipe. At this time, since the lower end side of the column main body is formed in a hemispherical shape, the lower end side of the column main body can be inserted into the hole and erected so as to slide along the tapered portion of the buried pipe.

For this reason, the column main body can be erected in an upright state with respect to the hole of the buried pipe as in the prior art, and can be smoothly inserted even in an oblique state without being inserted into the hole.

Further, the contact area between the hemispherical surface at the lower end of the column main body and the tapered portion is small, and the insertion into the hole can be performed smoothly.

In addition, by expanding the diameter of the column body itself from the stopper part, it can be more easily inserted and erected in the hole. The pillar body can be erected.

Furthermore, since the tapered portion of the buried pipe can be blocked by the stopper portion of the column main body, the inflow of sand or the like into the hole can be prevented.

FIG. 1 is a schematic cross-sectional view showing a first embodiment of the draw-out type support column of the present invention, FIG. 2 is a schematic explanatory plan view showing the draw-in type post filling of FIG. 1, and FIG. FIG. 4 is a schematic cross-sectional view showing a second embodiment of the pull-out column of the invention, FIG. 4 is a schematic cross-sectional view showing a third embodiment of the pull-out column of the present invention, and FIG. FIG. 10 is a schematic explanatory sectional view showing a fourth embodiment of the column according to the invention.

(First embodiment)
The pulling-type column 1 of the present invention is composed of a cylindrical buried pipe 2 buried in the ground and a column body 3 standing on the ground by being inserted into a hole 4 of the buried pipe 2.

The hole 4 inside the buried pipe 2 is formed with a hole 4 into which the lower end side of the column body 3 is inserted, and when buried, the upper end side of the hole 4 is a tapered portion that is wider than the diameter of the buried pipe 2 along the upper side. 5 is formed. For this reason, the diameter of the hole 4 can be made larger than the insertion portion.

The column main body 3 has a lower end portion 6 formed in a hemispherical shape, and can be inserted into the hole 4 while moving so as to slide along the tapered portion 5 of the embedded pipe 2. For this reason, it can insert, without making the pillar main body 3 perpendicular | vertical to the hole 4, and matching the hole 4 and the lower end part 6 appropriately.

An arcuate stopper portion 7 that stops insertion into the hole 4 of the buried pipe 2 is attached to a desired position of the column main body 3. The stopper portion 7 is formed in a reverse taper shape on the lower surface side and formed in a horizontal shape on the upper surface side, and can appropriately close the taper portion 5 of the buried pipe 2.

The plug-and-support column 1 of the present invention is configured as described above. Next, the case where the plug-and-plug column 1 is used as a column for a rugby goal will be described.

Two holes are drilled in the outdoor field, and the buried pipes 2 are each buried in a vertical state in the ground. At this time, the taper portion 5 of the buried pipe 2 is completely buried.

Next, the lower end portion 6 of the substantially H-shaped column main body 3 constituting the post for the rugby goal lifted by the heavy machinery is located at a part of the taper portion 5 on the upper end side of the buried pipe 2, and the column main body is based on this. The lower end portion 6 of the column main body 3 is moved to the hole 4 side along the tapered portion 5 while the column main body 3 is erected, and the column main body 3 is inserted into the hole 4 up to the stopper portion 7.

As described above, the column main body 3 can be inserted into the hole 4 of the buried pipe 2 and erected on the ground to form a rugby goal.

Further, when the column main body 3 is erected, the tapered portion 5 of the embedded tube 2 is closed by the stopper portion 7, so that sand or the like can be used without flowing into the hole 4 of the embedded tube 2 during use.

For this reason, it does not require much labor to erect the column body 3 as in the prior art, and a smooth operation can be performed.

Further, when the column main body 3 is extracted from the hole 4 of the buried pipe 2, since the sand or the like does not flow into the hole 4, the column main body 3 can be extracted smoothly.

(Second embodiment)
In the first embodiment, the upper surface side of the stopper portion 7 attached to the column main body 3 is formed horizontally. However, the column main body 3 is formed in the hole 4 of the buried pipe 2 by forming the upper surface side in a tapered shape. The strength when inserted and standing can be secured.

(Third embodiment)
In the first embodiment, the tapered portion 5 of the buried tube 2 is formed wider than the diameter of the buried tube 2, but the tapered portion 5 is formed by increasing the cross-sectional portion of the hole 4 of the buried tube 2. By forming the same shape as the diameter of the stopper portion 7, the stopper portion 7 can be formed in a narrow shape, and the cost can be reduced.

(Fourth embodiment)
In the third embodiment, the tapered portion 5 and the buried pipe 2 are formed to have the same diameter, so that the stopper portion 7 is formed narrow. However, if the stopper portion 7 is narrow, the column body 3 itself By expanding the diameter from the stopper portion 7, it is possible to more easily deliver the column body 3 to the hole 4 and stand upright.

As described above, the pull-out column 1 of the present invention can be easily inserted into the buried pipe 2 of the column body 3 and has a smooth workability, and can prevent the inflow of sand or the like.
