Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention relates to a curb mounting structure provided along a boundary between a track and a field in an athletic field.

<Prior Art> Curbs on an athletic stadium can be a hindrance in field games such as soccer, rugby, or high jump. For this reason, the applicant of the present invention has developed a detachable curb
63-165306).

To install this curb, a support with an insertion hole on the upper surface is buried in the ground with the upper end flush with the ground surface, and the lower part of the rod-shaped connecting body hanging from the lower surface of the curb is supported above. It is removably fitted into the fitting hole of the body.

<Problems to be solved by the invention> However, in the above-mentioned detachable curb, even if the curb is positioned at the standard position at the time of verification by burying the support at a predetermined position during construction, it takes several years. If used over a period of time, a person may ride on the installed curb, or the removed curb may not be stored properly, so the curb may be slightly bent or the position of the support may be displaced. . When such a situation occurs, not only can the work of removing and installing the curb not be performed smoothly, but the position of the curb deviates from the standard and the next verification cannot be passed. Therefore, the curb had to be replaced with a new one, or the support had to be dug up and buried again.

Under these circumstances, it was desired to develop a tool that can adjust the position of the curb to some extent.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and has a long curb having an internal thread portion on the lower surface and a fitting hole on the upper surface, and the upper end is flush with the ground surface. A support body that is buried in the ground, a leg portion that has a leg portion that fits in a fitting hole of the support member in the lower portion, and a male screw portion that is in the upper portion, and a male screw portion of the joint member are pierceable. And a bracket that has a long hole with a long diameter in the width direction of the curb and can contact the lower surface of the curb. The bracket is fixed to the lower surface of the curb with bolts, and the male screw part of the connecting body is inserted in the long hole of the bracket. To connect the bracket to the bracket by screwing a nut into the male screw portion,
The leg portion of the connecting body is detachably fitted into the fitting hole of the support body.

<Operation> When the nut is loosened and the male screw portion of the connector is moved and adjusted in the elongated hole of the bracket in the width direction, the position of the curb can be adjusted in the width direction. Therefore, by this, the position of the curb is adjusted to the predetermined position allowed by the standard.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

The athletic stadium is composed of an oval-shaped track having a straight road and a corner road, an infield surrounded by the track, and a shout field located outside the track, and the boundary between the track and the infield. The curb 1 according to the present invention is arranged in a portion. Therefore, the support 2 is embedded in the ground at the boundary so as to be flush with the ground surface GL, and the upper end of the connecting body 3 fitted to the support 2 is fixed to the bracket 4 of the curb 1. There is.

The support body 2 is a metal columnar body made of stainless steel or the like, and has a fitting hole 5 formed in the upper surface thereof and a retaining collar portion 6 formed at the lower end thereof. The fitting hole 5 is set to have the same length as the lower leg portion 7 of the connecting body 3.

The connecting body 3 is a metal columnar body made of stainless steel or the like, and has a male screw portion 9 to be screwed into the bracket 4 formed in an upper portion having a smaller diameter than a large diameter portion having the parallel surfaces 8 and 8 and a lower portion in the lower portion. The leg portion 7 is formed in the fitting hole 5 of the support body 2 so as to have a size to be fitted therein.

The curb 1 is a long tubular member made of aluminum or the like with a rectangular cross section, and two rising pieces 10, 10 facing the upper surface of the lower surface are provided in the longitudinal direction.
Female threads are engraved on the mutually facing surface and the lower surface to form a plurality of female threaded portions 11 at predetermined intervals, and bolts 12 are screwed into the female threaded portions 11 to attach the bracket 4. There is.

As shown in FIG. 1, the bracket 4 is formed by bending a metal plate such as a stainless steel plate, and the front and rear parts in the longitudinal direction are erected upward and bent outward to bend the front and rear flange portions 13,13. Both flange parts 1
A concave portion 14 is formed between 3, 13, a circular bolt through hole 15, 15 is opened in the flange portion 13, and a long hole 16 having a long diameter in the width direction is formed in the approximate center of the concave portion 14. To do. Therefore, when the bolt 12 is passed through the through hole 15 of each flange portion 13 from below and the tip portion of the bolt 12 is screwed into the female thread portion 11 of the curb 1 and tightened, the bracket 4 is attached to the lower surface of the curb 1. It can be fixed in abutting state.

When the curb 1 is installed in the stadium, the connecting body 3 is fixed to the bracket 4 in advance. In this case, since the recess 14 of the bracket 4 is narrow, it is desirable to use the jig 17. As shown in FIG. 5, the jig 17 is formed by bending a metal plate into a U-shape, and locking a notch 19 in which a nut 18 is fitted to the lower piece, and fixing the upper piece and the lower piece. The distance from the piece is set to be slightly larger than the thickness of the curb stone 1. Therefore, when the upper piece of the jig 17 is placed on the upper surface of the curb 1 from the side,
The lower piece just fits into the recess 14 of the bracket 4. In this state, the nut 18 is put into the recess 14 and is housed in the notch 19, and the upper male screw portion 9 of the connecting body 3 is inserted into the slot 16 of the bracket 4.
When the connecting body 3 is rotated by penetrating it from below, the male screw portion 9 is screwed into the nut 18 by this rotation, and a spanner is applied to the parallel surfaces 8 and 8 of the large diameter portion to further rotate the connecting body 3. When you move
The connecting body 3 is firmly fixed to the lower surface of the bracket 4. Since the male screw portion 9 can move in the width direction in the elongated hole 16 when the connecting body 3 is not firmly tightened, the fastening position of the connecting body 3 can be adjusted in this state.

With the connecting body 3 fixed to the bracket 4 as described above, the leg portion 7 of the connecting body 3 is fitted into the fitting hole 5 of the support body 2 so that the large diameter portion abuts on the upper end of the support body 2. Up to (Fig. 2). With this configuration, the height from the lower end of the large-diameter portion of the connecting body 3 to the upper surface of the curb 1 is preset according to the standard, so that the curb 1 is positioned at the standard height. Further, since the support body 2 is also embedded so that the curbstone 1 is located at a predetermined position, the curbstone 1 is also located at the standard position in the horizontal direction.

Then, when the curb 1 is bent a little during use for many years and the position of the curb 1 is misaligned, the connecting body 3 is loosened. In this way, the bracket 4 becomes movable in the width direction integrally with the curb 1, so that the position of the curb 1 can be adjusted. Therefore, the position of the curb 1 can be corrected to a predetermined position defined by the standard, and the next inspection can be passed.

It should be noted that the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the configuration described in the utility model registration claim is not changed.

For example, even if the female threaded portion 11 of the curb 1 is formed by simply opening a female screw hole on the lower surface of the curb 1, the rising piece 1
It does not have to be 0 or 10. Further, after removing the curb 1 by pulling out the leg portion 7 of the connecting body 3 from the fitting hole 5 of the support body 2, the fitting hole 5 is covered so that earth and sand do not enter the fitting hole 5 of the support body 2. You may make it fit.

<Effect of Device> As described above, according to the present invention, if the curb is positioned at the standard position at the time of certification, then a person can ride on the curb installed or the curb removed. Even if the curbstone is slightly bent due to improper storage of the support, or the position of the support is misaligned, loosen the screwing of the connector and the nut and loosen the male thread of the connector from the bracket. The position of the curb can be easily adjusted in the width direction of the curb by moving the curb in the width direction in the long hole. Therefore, the curb can always be installed at a predetermined position defined by the standard without replacing the curb with a new one, and the next verification can be easily passed.
