Abstract

PURPOSE: To provide the neat and straight connection, and to keep the prescribed angle of refraction by surely fixing the angle of connection of a hooking bar which is hooked between adjacent cone blocks. CONSTITUTION: A hooking member 3 having an annular hooking part 4 with a round hole 5 being cut therein is fixed to each end of a rod 2. When other annular hooking part is lapped over the annular hooking part 3 in the axial direction, the angular displacement in the circumferential direction is prevented to constitute an angle fixing and fitting structure 11 to be separably fitted in the axial direction. A hooking bar 1 is hooked between the top parts of the continuously arranged cone blocks, and neat connection is realized straightly or at the prescribed angle by the angle fixing and fitting structure 11.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension for a cone block for suspending the passage between the cone blocks which are suspended between the tops of the display cone blocks such as a work area used at a work site. It's about improving the bar.

[0002]

2. Description of the Related Art Conventionally, a cone-shaped restriction block called a cone block has been used as a means for restricting the passage of people and vehicles at a construction site or the like, and the blocks are arranged side by side in the direction in which they are guided. There is. A cone block hanging bar is used between the tops of adjacent cone blocks for the purpose of preventing passage between the cone blocks.

Generally, in this type of hanging bar for a cone block, an annular hanging member having a circular hole to be inserted into the top of the cone block is 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 frame.

[0004]

That is, since the conventional hanging bar for cone blocks has a structure in which a ring-shaped hanging member is simply fitted on the top of the cone block, it is arranged between the adjacent cone blocks in sequence. It was impossible to fix the connecting angle when installing the hanging bar, and there was a problem that it was not possible to connect in a straight line orderly without waviness or to maintain a predetermined refraction angle. .

The present invention has been made in view of the above problems, and when an annular hanging member continuous with a cone block is externally stacked, the upper and lower annular hanging members are set at angular positions in the circumferential direction. It is possible to fix, and it is possible to reliably fix the connecting angle of the hanging bars installed between the adjacent cone blocks in order, and to connect the hanging bars in an orderly linear manner without waviness, An object of the present invention is to provide a hanging bar for a cone block having an angle fixing fitting structure capable of maintaining a refraction angle.

[0006]

A hanging bar for a cone block according to the present invention is a hanging bar for a cone block, which is hung between the tops of conical cone blocks arranged side by side and prevents passage between them. In, at both ends of the frame of appropriate length,
At the top of the cone block, a hanging member having an annular hanging portion having a circular hole for external insertion is fixedly mounted, and another annular hanging portion is axially stacked on the annular hanging portion. When loaded,
The gist of the present invention is to construct an angle fixing fitting structure that prevents angular displacement in the circumferential direction and fits so as to be split in the axial direction.

In addition, the hanging bar for the cone block has an angle fixing fitting structure formed in the annular hanging portion of the hanging member, in the axial direction at an equal angular pitch in the circumferential direction of the annular hanging portion. It is composed of a plurality of fitting holes penetrating to each other, and a fitting projection protruding at one of the fitting hole positions with a fitting relationship such that the sliding pressure is appropriately applied to the fitting hole and which can be inserted and removed. be able to.

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

[0009]

In the above structure, the hanging bar for the cone block is
(1) A plurality of fitting holes penetrating axially in the circumferential direction of the annular hanging portion at an equal angular pitch in the annular hanging portion of the hanging member, and appropriately sliding to the fitting holes. One that is composed of a fitting protrusion that is provided at one of the fitting hole positions with a fitting relationship that allows insertion and removal with dynamic pressure. (2) A plurality of concavo-convex structures formed at equal angular pitches in the circumferential direction of the annular hanging portion, and fine cut undercuts formed on the standing wall of the concavo-convex structure. It has a fixed angle fitting structure.

In the former case (1), when the circular hanging portions are stacked by inserting the circular holes formed in the hanging members of the two hanging bars connected to the top of the cone block, the annular hanging portions are projected. The fitting protrusion of the one hanging member provided is fitted into 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 concavo-convex structures formed at equal angular pitches in the circumferential direction of the portions are fitted to each other. Since the undercut having a fine angle is formed on the standing wall of the uneven structure, the fitting of the uneven structure prevents angular displacement in the circumferential direction and at the same time prevents the fitting from being naturally disengaged.

Therefore, the angle fixing fitting structure can fix the angular positions of the upper and lower annular hanging members in the circumferential direction, and the connecting angle of both hanging bars connected at the top of the cone block. It becomes possible to fix the hanging bar, and it is possible to connect the hanging bars linearly without waviness or to install and maintain the hanging bar at a predetermined refraction angle.
