Abstract

PROBLEM TO BE SOLVED: To facilitate the assembling and disassembling of a clamp, prevent rolling and contrive the firm fixing of the clamp by projecting the edge side of the bolt of nut screwing, and burying it by insert molding so that a nut end face is exposed. SOLUTION: A post 1 is connected by a plurality of pipes 3 to form a moving fence, and the bolt 6 and the nut are the top part 7 of the post 1 and the bridging part of the lower part respectively. In this case, the bolt 6 makes the head part 6a downward to project the screw part 6b of the edge from the outer face of the post 1 so as to be buried. Furthermore, the nut is buried so that the end face 5a is flush with the outer face of the post 1. The bolt 6 and the nut are buried by insert molding, and when being fixed to the post 1 of the clamp 4, the clamp 4 is sandwiched by the buried nut and a tightening nut 9 to be firmly tightened. The looseness of the tightening nut 9 is suppressed, and the clamp 4 is firmly fixed. Thereby the clamp 4 is firmly fixed, and the rolling and the damage of the assembled moving fence are prevented to improve stability.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a moving fence which is installed on a road for displaying a traffic division, and more particularly to a column which constitutes the moving fence.

[0002]

2. Description of the Related Art A moving fence has, for example, a structure in which a horizontal member such as a pipe (hereinafter, simply referred to as a "pipe") is fixed to a standing pillar facing up and down. It is widely used for danger prevention and for indicating traffic congestion. By the way, the pillars of the conventional moving fence are often made of metal members firmly,
If it is made of metal, the moving fence becomes heavy, forcing the worker to perform heavy labor in terms of transportation and storage management, and rust easily occurs, so that the appearance at the time of use deteriorates, and additional costs are required for repair and the like.

In order to cope with this, recently, columns of a movable fence made of synthetic resin have been seen. In this case, a column made of synthetic resin and a metal column for fixing a pipe are used. Fixing fittings such as clamps (in this specification,
Simply called "clamp". ) Often have problems with the structure that connects In other words, if the support is made of synthetic resin, the connection may be deformed, so that the support and the clamp cannot be firmly fixed in many cases. In addition, there is a problem that safety is lacking, and furthermore, there is a possibility that the device may be damaged when a lateral load is strongly applied.

[0004]

SUMMARY OF THE INVENTION The present invention solves the problems of the above-mentioned conventional moving fence support, reduces the burden on transportation and management, and facilitates assembly and disassembly of the clamp. Moreover, it is an object of the present invention to provide a movable fence support that can prevent a roll and the like and firmly fix a clamp.

[0005]

In order to achieve the above-mentioned object, according to the present invention, there is provided a moving fence support which is formed of a synthetic resin. A bolt in which a nut is screwed is embedded in a support post by insert molding so that the tip side protrudes and an end face of the nut is exposed. In this case, the bolt to which the nut is screwed is attached to a clamp, for example, buried in a top portion of a column, a lower bridge portion, or the like.

In the support of the moving fence according to the present invention, the support is formed of a synthetic resin that is light and rust-proof, so that the burden on transportation and management can be reduced, and the fixing bolt is integrated with the support by insert molding. , The clamp can be easily assembled and disassembled, and the clamp can be clamped between the end face of the nut screwed into the bolt and the embedded nut and the fastening nut, so that the clamp can be firmly fixed. .

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 to FIG. 4 show an embodiment of a column of a moving fence according to the present invention. The moving fence 2 in which the column 1 of this embodiment is used is not particularly limited, but as shown in FIG. 4, pipes 3 are vertically inserted into a pair of columns 1 standing up and facing each other. The pipes 3 are respectively fixed to the columns 1 via clamps 4. The clamp 4 is of a type in which the pipe 3 is fixed to the pipe holding hole by fastening one end of a pair of upper and lower holding brackets forming a circular pipe holding hole and fastening the other end with a bolt. , Any type of clamp can be used.

In this embodiment, the column 1 of the movable fence 2 is formed of a synthetic resin, and the bolt 6 to which the nut 5 is screwed is formed such that the tip end projects and the end face 5a of the nut 5 is exposed. The support 1 is buried in the upper and lower portions by insert molding.

The column 1 is formed of a hollow resin-integrated molded product by blow molding, and has a substantially triangular shape having an A shape in side view. By connecting a plurality of the pillars 1 with the pipes 3, the movable fence 2 which can stand on its own is formed. The bolts 6 and the nuts 5 are buried in the top 7 and the lower bridging portion 8 of the column 1, respectively. The bolt 6 is buried so that the threaded portion 6b at the tip slightly protrudes from the outer surface of the column 1 with the head 6a down, and the nut 5 has an end surface 5a that is flush with the outer surface of the column 1. It is buried to be one.

By burying the bolt 6 and the nut 5 by insert molding in this way, as shown in FIG. 3, when the clamp 4 is fixed to the column 1, the buried nut 5 and the fastening nut 9 are fixed. , The clamp 4 can be firmly fixed without the tightening nut 9 being loosened. In addition, bolt 6
If there is no nut 5 in the burial only, tighten the nut 9
It is not preferable that the column 1 is loosened because the column 1 is a resin product and cannot be firmly fixed.

As described above, the column 1 of the moving fence of the present embodiment.
Since it is a hollow body and integrally molded with resin, it is extremely lightweight and does not rust, so that the burden on the site in terms of transportation and management can be reduced. Since the fixing bolt 6 is embedded by insert molding to be integrated with the column 1, the assembly and disassembly of the clamp 4 can be facilitated. Further, as shown in FIG. Since the clamp 4 can be sandwiched between the end face 5a of the nut 5 embedded and the fastening nut 9, the clamp 4
Can be firmly fixed, the movable fence 2 assembled can be prevented from rolling and being damaged, and its stability and safety can be improved.

In this embodiment, the bolt 6 screwed with the nut 5 is buried in the top 7 and the lower bridging portion 8 of the column 1 and the like.
The embedding position is not limited to that of the present embodiment, but can be embedded at any position.

Further, the configuration of the present invention is not limited to fixing the clamp 4, but also directly fixes the perforated pipe by changing the protruding length of the screw portion of the embedded bolt 6 according to the object to be fixed. Or fixing other objects can be easily performed.

[0015]

According to the movable fence support of the present invention, the support is formed by a light and rust-resistant synthetic resin, so that the burden on transportation and management can be reduced, and the fixing bolt is integrated with the support by insert molding. As a result, the clamp can be easily assembled and disassembled, and the clamp can be clamped between the end face of the nut embedded with the bolt and the tightening nut. In addition, the assembled moving fence can be prevented from rolling or being damaged, and its stability and safety can be improved.
