DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corn block hanger for blocking a block between corn blocks which are spaced apart from each other by being hung between the tops of display corn blocks for use in a work site or the like. It relates to the improvement of the bar.

[0002]

2. Description of the Related Art As means for restricting the traffic of people and vehicles at a construction site or the like, a conical control block called a cone block has conventionally been used, and is provided side by side in the direction in which it is to be guided. I have. In order to prevent the passage between the cone blocks, a hanging bar for the cone block which is bridged between the tops of the adjacent cone blocks is used.

Generally, this type of hanging bar for a cone block has an annular hanging member having a circular hole formed in the top of the cone block and having a hole to be extrapolated, fixed to both ends of a rod having an appropriate length. The structure has a camouflage color in which yellow and black are alternately painted on the rod.

[0004]

That is, the conventional hanging bar for a cone block has a structure in which an annular hanging member is simply extrapolated to the top of the cone block, so that it is arranged between adjacent cone blocks in sequence. When the hanging bar is erected, it is impossible to fix the connection angle, and there is a problem that it is not possible to make a straight and linear connection without waving or to maintain a predetermined refraction angle. .

The present invention has been made in view of the above-mentioned problems, and when an annular hanging member that is continuous with a cone block is extrapolated and stacked, the upper and lower annular hanging members are adjusted in angular position in the circumferential direction. It is possible to fix the connecting angle of the hanging bar erected between the adjacent cone blocks sequentially, and it is possible to connect the hanging bar neatly and linearly without waving, It is an object of the present invention to provide a hanging bar for a cone block having an angle fixing fitting structure capable of maintaining a refraction angle.

[0006]

SUMMARY OF THE INVENTION A cone block suspension bar according to the present invention is suspended between the tops of conical cone blocks spaced apart and juxtaposed to prevent passage therebetween. In, at both ends of the rod of appropriate length,
At the top of the cone block, a hanging member having an annular hanging portion having a circular hole to be extrapolated is fixedly mounted, and another annular hanging portion is placed on the annular hanging portion in the axial direction. When stacked
An angle fixing fitting structure that prevents angular displacement in the circumferential direction and fits separably in the axial direction is provided in the circumferential direction of the annular hanging portion.
The gist of the present invention is to configure the camera at a plurality of angular positions .

[0007] The hanging bar for the cone block may further comprise an angle fixing fitting structure formed on the annular hanging portion of the hanging member, and may be formed in an axial direction at an equal angular pitch in a circumferential direction of the annular hanging portion. And a fitting projection protruding at one of the fitting hole positions with a mating relationship capable of being inserted and removed with an appropriate sliding pressure with respect to the fitting hole. be able to.

Alternatively, the hanging bar for the cone block has an angle fixed fitting structure formed on an annular hanging portion of the hanging member at an equal angular pitch in a circumferential direction of the annular hanging portion. It is also possible to comprise a plurality of uneven structures formed as described above and an undercut having a fine angle formed on a standing wall of the uneven structure.

[0009]

In the above construction, the hanging bar for the cone block is
(1) A plurality of fitting holes that penetrate in the axial direction at equal angular pitches in the circumferential direction of the annular hanging portion, and slide appropriately with respect to the fitting holes. One that is formed of a fitting projection protruding from one of the fitting hole positions with a dynamic pressure-fitting removable fitting relationship. (2) A structure comprising a plurality of uneven structures formed at equal angular pitches in the circumferential direction of the annular hanging portion, and an undercut having a fine angle formed on a standing wall of the uneven structure. And so on.

In the case of the former (1), when a circular hole formed in the hanging member of the double hanging bar connected to the top of the cone block is extrapolated to stack the annular hanging portion, the annular projecting portion projects. The fitting projection of one of the hanging members provided is fitted to one of the fitting holes of the other hanging member to prevent angular displacement in the circumferential direction.

In the latter case (2), when the annular hanging portions are stacked, a plurality of concave and convex structures formed at equal angular pitches in the circumferential direction of the annular fitting portions are fitted to each other. Since the undercut having a fine angle is formed on the standing wall of the uneven structure, the angular displacement in the circumferential direction is prevented by the fitting of the uneven structure, and the fitting does not naturally come off.

Therefore, the angle fixing fitting structure can fix the angular position of the upper and lower annular hanging members in the circumferential direction, and can set the connecting angle of the two hanging bars connected at the top of the cone block. The hanging bars can be fixed, and the hanging bars can be connected linearly without waving or can be installed and maintained at a predetermined refraction angle.
