DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device used for erecting a brace at a doorway of a park or the like.

[0002]

2. Description of the Related Art At the entrances and exits of parks and at the boundaries between roads and sidewalks, there are cases where a brace post is erected to restrict the traffic of vehicles and people.

[0003] In order to bury this type of brace post, it is usually applied by the following means. That is, an anchor projecting outward at the lower end of the column is fixed in advance,
A hole is dug in the ground at the position where the brace post is to be buried, and concrete is poured to a certain height to make a foundation. At this time, the difference bars are projected from the concrete base. Then, when the concrete base is fixed, a brace post is inserted into the hole, and the anchor of the post and the difference metal are welded and fixed. Furthermore, the concrete is poured into the hole around the brace post again, and when it hardens, the upper surface is paved. Thus, the bollard strut is buried underground.

[0004]

By the way, in such a conventional structure, a vertically long support is used. In order to obtain the verticality, a piece of wood or the like falling around the support is fixed between the brace support and the concrete base. Inserting and fine-tuning will be necessary, but until the support is welded and fixed, it is necessary to always support by hand so that the brace post does not tilt, and multiple workers can perform one operation. I needed it. In addition, particularly when the pillars are heavy, the work is dangerous.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device for supporting a brace post which does not have the above-mentioned drawbacks.

[0006]

According to the present invention, a mounting plate is fixed to the lower surface of a cylindrical fitting body having a plurality of screw holes into which a pressing screw is screwed from the outside, and A bottomed cylindrical driving metal fitting having a plurality of fixing anchors fixedly attached to the reinforcing bars implanted on the base plate on the mounting plate, and fixed to a lower end of a brace post, The outer diameter is smaller than the inner diameter of the driving fitting, and the lower end is supported by the mounting plate, and is inserted into the cylindrical fitting of the driving fitting, and the leading end of each pressing screw screwed from the screw hole. And a buried pipe that is clamped and fixed to the driving fitting .

According to the first aspect of the present invention,
In this configuration, the fixing anchor has a pipe structure in which a screw hole is formed so as to be slidably fitted to the difference bar, and a screw hole for screwing a tightening screw for fixing to the difference bar is formed on the side surface.

Further, according to a second aspect of the present invention, the buried pipe fixed to the lower end of the brace post is longer than the height of the cylindrical fitting, and the cylindrical fitting is positioned from the lower end position. An embedding anchor to be buried in the mortar is protruded above the height of the mortar .

[0009]

First, a bottomed cylindrical driving metal fitting is placed on a concrete base, and a fixing anchor vertically attached to the driving metal fitting is made as perpendicular as possible to a reinforcing bar projecting upward from the concrete base. So as to fix it. Since this fixing work is performed before the vehicle stop prop is mounted, the load becomes light and the workability is good. Then, the buried pipe at the lower part of the brace is inserted into the tubular fitting of the fixed driving fitting, the load is supported by the mounting plate, and a pressing screw is screwed into the screw hole of the driving fitting. Then, by fixing the buried pipe at the tip of each pressing screw, the brace is fixed to the driving fitting. After that, concrete is poured into the holes, and when it hardens, the upper surface is paved. Thus, the bollard strut is buried underground.

In this structure, the fixing anchor is movably supported in the long hole formed in the mounting plate of the driving tool .
In this case , in this case, a piece of wood or the like is inserted between the driving fitting and the concrete base to adjust the height, and further, the fixing anchor is moved along the long hole so as to move upward from the concrete base. Adjust the movement in the left and right direction so that it comes into contact with the streaks protruding from This makes it possible to easily fix the driving fitting by welding.

According to the first aspect of the present invention, since the fixing anchor has a pipe structure , the anchor can be screw-fixed by being externally slidably fitted to the difference bar. For this reason,
There is no need to insert a piece of wood or the like between the driving fitting and the concrete base, and the height position can be easily adjusted.

Further, in claim 2 of the present invention,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

The device for supporting a bollard post of the present embodiment comprises a bottomed cylindrical driving fitting 1 buried underground and a buried pipe 12 screwed to the bogie post 10.

The driving fitting 1 has a bottomed cylindrical shape in which a mounting plate 3 is fixed to a lower surface of a cylindrical fitting 2 so as to cover a hole of the fitting 2. The body 2 has three screw holes 4 at equal angular intervals. In each corner of the mounting plate 3, a long hole 5 is formed in a diagonal direction, and an L-diameter fixing anchor 6 is fixed to the long hole 5. The fixing anchor 6 has a male screw portion 7 formed at the upper end thereof. The male screw portion 7 is inserted into the elongated hole 5 from below, and nuts 8 and 9 are screwed from above and below the elongated hole 5. It is detachably fixed by the tightening of 8,9. By loosening the nut 8, the fixing anchor 6 can be moved along the elongated hole 5, and the vertical and horizontal positions can be adjusted by the inclination of the elongated hole 5.

On the other hand, the bollard support post 10 has a female screw 11 formed on the inner surface at the lower end thereof, and a male pipe 11 formed at the upper end of the female screw 11 with an embedded tube 12 having an outer diameter smaller than the inner diameter of the driving fitting 1. The screw portion 13 is screwed and fixed to the female screw 11.

The length of the buried pipe 12 is longer than the height of the tubular fitting 2, and the embedding anchors 14 are arranged at equal intervals from the lower end position to a position higher than the height of the fitting 2. The four project in the horizontal direction.

In such a configuration, it becomes possible to form the brace post 10 by casting and the buried pipe 12 by stainless steel pipe or the like. In addition, the buried pipe 12 may be formed integrally with the wheel stopper support 10 using the same material.

Next, the construction means having such a configuration will be described with reference to FIG. First, a hole h is dug at a required position on the ground, and concrete is poured to a certain height to make a base a.
At this time, the difference bars b protrude from the concrete base a.
Then, when the concrete base a is fixed, the bottomed cylindrical driving fitting 1 is positioned on the concrete base a in the hole h, and a piece of wood or the like is driven so as to be as vertical as possible.
And fine adjustment is performed by inserting it between the concrete base a and the anchor 6 projecting from the driving fitting 1 by welding to the reinforcing bar b. At this time, the anchor 6 is supported by screwing nuts 8 and 9 from above and below the long hole 5.
Rotation is possible by loosening 9, and the height can be adjusted by adjusting the position of the upper nut 8. Furthermore, the long hole 5 enables vertical and horizontal movement adjustment in the plane direction. For this reason, for example, even if the position of the difference streaks b is not uniform, it is possible to move the fixing anchor 6 and place it at a position where it is in contact with the difference streaks b.
And the stud b can be easily welded.

Next, the buried pipe 12 below the brace 10 is inserted into the fitting 2 of the driving fitting 1, and the lower end thereof is supported by the mounting plate 3 to receive a load. Thereby, the holding of the wheel stopper support 10 can be stably performed.

Thereafter, a pressing screw 15 is screwed into the screw hole 4 of the driving metal fitting 1, and the buried pipe 12 is clamped at the tip of each pressing screw 15, so that the brace 1 is attached to the driving metal fitting 1.
0 is fixed. At this time, the verticality of the brace 10 can be precisely positioned because it can be slightly inclined with respect to the driving tool 1. Fine adjustment of the height position is also possible by loosening the pressing screw 15 and re-clamping. Then, after the positioning, the mortar is poured into the hole h again. When the mortar is cured, the buried pipe 1
The embedding anchor 14 protruding from 2 is to be embedded in the mortar. For this reason, even if the pulling force is applied to the brace 10, the buried pipe 12 is firmly buried in the ground and cannot be pulled out.

Thus, the brace 10 is buried underground. A plurality of the baffle struts 10 are provided at the entrance of the park or at the boundary between the road and the sidewalk, and an intrusion prevention chain or rod is interposed between the struts as necessary.

In this construction step, after holding and solidifying the relatively lightweight driving fitting 1, it is only necessary to insert the brace 10 into the driving fitting 1 and screw the pressing screw 15. Therefore, the mounting work can be performed by only one worker.

4 and 5 show another embodiment of the present invention.
This is a case where a fixing anchor 30 having a pipe structure is applied. In the drawings, the same components as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

A fixing anchor 30 is attached to each corner of the frame 3. The fixing anchor 30 is manufactured with good productivity by bending a metal plate, extends upward on the inner side surface of the holding pipe portion 31 having a U-shaped cross section, and bends the extended end. The fixing portion 32 is formed by welding the fixing portion 32 to the lower surface of each corner of the frame 3 described above.

A screw hole 34 is formed on the outer surface of the holding pipe portion 31, and a tightening screw 36 is screwed into the screw hole 34.

In the metal fitting 1 using the fixing anchor 30, the stud b is inserted into the holding pipe portion 31 to adjust the height of the metal fitting 1, and then the tightening screw 36 is advanced. Then, as shown in FIG. 5, the streak b is pressed by the tip, and the streak b is sandwiched between the side surface of the holding pipe portion 31. Thereby, the driving fitting 1 is fixed. In this means, there is no need to insert a piece of wood or the like between the driving fitting 1 and the concrete base a for adjustment, and the height can be easily adjusted. In addition, since the fasteners 36 are pressed and held by the fastening screws 36, fine adjustment of the inclination direction of the driving fitting 1 can be easily performed.

[0028]

According to the present invention, as described above, the driving tool 1
And the buckle support 10 having the buried pipe 12 is assembled so that the buckle support 10 is buried vertically, and its position is maintained by the lightweight driving fitting 1.
By simply inserting the buried pipe 12 of the brace 10 into the driving fitting 1 and tightening the pressing screw 15, the brace 1
0 can be held vertically, and the construction is easy. Therefore, the construction can be performed by one worker, and the work load can be reduced. Because it is supported by the frame 3, it is stably held.

According to the first aspect of the present invention , the struts b are inserted through the fixing anchor 30 and fixed by using the fixing anchor 30 having a pipe structure. Height adjustment becomes easy.

According to the second aspect of the present invention , the embedding anchor 14 is provided in the mortar by projecting the embedding anchor 14 from the embedding pipe 12 of the brace post 10.
4 is buried, the strength of the brace 10 is increased, and the brace 10 is not detached from the ground in the future.
