Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a guard post used for limiting the site of a park, school, house, etc. or the boundary between a roadway and a sidewalk.

[Conventional technology]

Conventionally, as this type of guard post, as shown in FIG. 5, a circular collar plate 3 is welded to the outside of the upper end of a hollow tube 2 whose upper and lower ends are open, and the lower surface of the collar plate 3 is welded. A plurality of nuts 4 are welded, and a tubular body 5 surrounding each of these nuts 4 is welded downward, and a mounting body 1 and a hollow tube 2 in the mounting body 1 are formed. The collar plate 3 is provided outside the lower part of the hollow tubular guard post body 7 to be loosely inserted.
Guard post body 6 to which a circular collar plate 8 that fits with is welded
The mounting body 1 includes the hollow pipe 2 and the tubular body 5 with the collar plate 3 exposed on the ground surface and the lower end of the hollow pipe 2 abutting on the crushed stone 9 for foundation cutting. Is embedded and fixed in the foundation concrete 10, the lower part of the guard post main body 7 is loosely inserted from the upper end opening of the hollow tube 2 of the mounting body 1, and the brim plate 8 is superposed on the brim plate 3. Board 3,
In general, a structure in which a bolt 11 is fastened to a nut 4 from above in a corresponding bolt hole 8 and a guard post body 6 is attached thereto.

[Problems to be solved by the invention]

By the way, the guard post may be detached from the guard post body for a certain period of time or for a certain period depending on the installation location.

In this case, in the conventional guard post, if the guard post body 6 is removed from the mounting body 1, the upper end of the hollow tube 2 in the mounting body 1 becomes an open state, which is very dangerous. Since rainwater, earth and sand, stones, etc. flow into the hollow tube 2 through the opening, the opening must be closed by a separately prepared lid plate, etc., which requires a lot of time and labor for the work. There was a problem that it was troublesome.

The present invention has been made in view of such conventional problems, and an object thereof is not to mention an opening on the ground surface when the guard post body is removed from the mounting body,
It is to provide a guard post with excellent safety in which no protrusions are exposed.

[Means for solving problems]

To this end, the present invention is directed to the foundation concrete 10
The mounting body 20 includes a mounting body 20 that is embedded and fixed in the inner surface of the circular mounting plate 21, and a guard post body 30 that can be attached to and detached from the mounting body 20.
The nut 22 communicating with the
An upper end of a rectangular cylindrical body 23 is welded to surround 22 and a rectangular bottom plate 24 as an anchor bolt is erected and fixed between the lower end surfaces of these two cylindrical bodies 23. 30 has a bolt hole 34 that matches each bolt hole 25 of the circular mounting plate 21, and is configured by vertically mounting and fixing a guard post body 32 on the circular mounting plate 31 that matches the circular mounting plate 21, The guard post body 30 has a circular mounting plate 31 superposed on the circular mounting plate 21 of the mounting body 20.
In addition, it is characterized in that the nuts 22 are erected and fixed to the nuts 22 through the corresponding holes of the bolt holes 25 and 34.

〔Example〕

Examples will be described with reference to the drawings. 1 is an overall vertical cross-sectional view, FIG. 2 is an enlarged vertical cross-sectional view of a main part, FIG. 3 is an enlarged cross-sectional view taken along the line III-III of FIG. 1, and FIG. In these figures, in the mounting body 20 which is embedded and fixed in the ground, nuts 22 communicating with the respective bolt holes 25 are welded and fixed to two positions in the diameter direction of the lower surface of the circular mounting plate 21. The upper end of a rectangular cylindrical body 23 is welded to surround 22 and further between the lower end surfaces of these two cylindrical bodies 23,
A rectangular bottom plate 24 having a function as an anchor bolt is constructed by being erected and fixed, and the mounting body 20 has a circular mounting plate 21 as a base cut crushed stone as shown in FIGS. 1 and 2. It is embedded and fixed in the base concrete 10 so as to have a substantially flat surface that is flat and flush with the surface (ground surface) of the base concrete 10 that has been cast onto the surface 9.

The guard post body 30 which is erected detachably on the mounting body 20 has a bolt hole which matches the bolt hole 25 of the circular mounting plate 21.
A warhead-shaped hollow tubular guard post main body 32 is erected and fixed on a circular mounting plate 31 having 34 and matching the circular mounting plate 21.

And the guard post according to the above-mentioned structure is a guard post body in the shape of a circular mounting plate 21 of the mounting body 20 embedded and fixed in the ground.
The circular mounting plates 31 of 30 are superposed and mounted, and the bolts 33 are integrally mounted by tightening the bolts 33 to the nuts 22 through the matching holes of the bolt holes 25 and 34 of the circular mounting plates 21 and 31. Used as.

When the guard post body 30 is no longer required to be used and the guard post body 30 is removed from the mounting body 20 by unfastening the bolts 33 and nuts 22 from each other, as shown in FIG. Is completely closed by the circular mounting plate 21 of the mounting body 20 and does not open, and projections such as bolts are not exposed at all, and the surface is substantially flush with the ground surface.

[Effect of device]

Thus, according to the present invention, the mounting body 20 fixed in the ground is fixed.
The guard post body 30 is attached to and detached from the guard post body 30 by tightening the bolts 33 and the nuts 22 to the circular mounting plates 21 and 31 of the stacking mount. The surface is not opened like the conventional one, but is completely closed by the circular mounting plate 21 and is in a flat surface state in which projections such as bolts are not exposed at all. Therefore, unlike the conventional case, it is extremely convenient because it does not require a cumbersome lid-hanging work with a lid plate or the like prepared separately for each case, and the circular mounting plate 21 of the mounting body 20 is firmly fixed and is affected by an external force. Since the mounting plate 21 does not move, and there are no protrusions on the surface of the mounting plate 21, there is no danger of tripping over the protrusions and the safety is excellent.

In addition, the mounting body 20 encloses each nut 22 and surrounds each nut 22.
And the rectangular bottom plate 24 as an anchor bolt is erected and fixed between the lower ends of the two cylindrical bodies 23, the mounting body 20 is extremely strong and the guard post body 30.
Tighten the bolt 33 to the nut 22 when installing
Since it is firmly supported by the rectangular cylindrical body 23 and the bottom plate 24, the circular mounting plate 21 can be firmly and firmly fastened without causing deformation.
