DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence reinforcing structure for temporarily and simply reinforcing a fence which is temporarily provided continuously for the purpose of displaying a construction and securing a place at a construction work site.

[0002]

2. Description of the Related Art In various construction and work sites such as construction and road construction, a fence in which a net, a plate, and the like are arranged in an outer frame of a pipe installed on an iron frame base or a concrete base is temporarily used. The length of this fence is usually about 1.8 m, and it is used continuously. As a reinforcing means in the case of the continuous installation, a single pipe having a length of about 5 m (for example, a steel pipe for a single pipe scaffold, JIS A 895)
1) is generally fixed to a pillar of the fence by a wire (wire). It is sufficient to fix the track for long-term reinforcement, but it is inconvenient to frequently attach and detach a single pipe.
It is uneconomical and the used wires become industrial waste. For this reason, various types of reinforcing tools and the like have been conventionally proposed. For example, in Japanese Utility Model Publication No. 48-42553,
As a barricade that can be provided with a connecting tool, a plurality of engaging holes are appropriately provided in legs of the barricade, and a connecting tool having an engaging portion that engages with the engaging hole is provided. Is disclosed. Further, Japanese Utility Model Publication No. 63-46501 discloses a guard fence connection product in which left and right holding rings into which pillars of adjacent guard fences are inserted, and an arc-shaped mounting provided on the connection back of the holding ring. There is disclosed a configuration in which a holding arm is formed of an elastic body, and a reinforcing pipe can be inserted into and removed from the mounting and holding arm. Further, in Japanese Utility Model Publication No. 4-39855, as an instrument for fixing a safety fence, an elastic plate is attached to both ends of an adjacent safety fence post, and a rod (an attachment mechanism) inserted into a central through hole of the elastic plate. ) Discloses a configuration in which a connecting horizontal steel pipe is engaged. Furthermore,
In Japanese Utility Model Laid-Open Publication No. Hei 3-5721 and Japanese Utility Model Laid-Open Publication No. Hei 6-8642, a pair of joint components and a connecting piece for clamping a column of an adjacent fence are fastened and fixed with bolts and nuts as fence clamps and connecting hardware. There is disclosed a configuration in which a single clamp for tightening and fixing a pipe is provided at the same time.

[0003]

However, the conventional reinforcing device has the following problems. In the barricade which can be provided with the connector of Japanese Utility Model Publication No. 48-42553, the position of the engagement hole is fixed, so that the degree of freedom of the mounting position of the single pipe is small, and the engagement state of the connector in the engagement hole is also small. There is a problem that the reliability is insufficient when the frequency of attaching and detaching the single pipe is high because of simple insertion. Further, in the connection product of the guard fence disclosed in Japanese Utility Model Publication No. 63-46501, the distance between the columns of the adjacent fences is fixed, and the degree of freedom of use when the fences are arranged at a distance is limited. In addition, the left and right holding rings are rotationally inserted between the columns and fixed by friction.However, not only is the rotation insertion work troublesome, but it cannot be said that the friction fixing is sufficient to support a single pipe, The supporting force drops sharply due to slippage. Further, when the single pipe is detached, there is a problem that the mounting and holding arm is in a protruding state, resulting in a work obstacle. In addition, the safety fence fixing device disclosed in Japanese Utility Model Publication No. 4-39855 not only requires a sharp reduction in the supporting force due to the settling of the elastic plate, but also requires a strong construction of the horizontal steel pipe. Is inappropriate. Furthermore, Japanese Utility Model Laid-open No. 3-5721 and Japanese Utility Model Laid-open No. 6-864.
The fence clamp and the connecting hardware disclosed in Japanese Patent Publication No. 2 are not only limited in the degree of freedom of use of the fence as in the case of the fixed fence of the adjacent fence, but also have a large number of components and are not compact. In addition, since the connecting piece is clamped from the front and rear of the fence support and the bolts are also tightened in the front and rear direction, there is a problem in the mounting workability. Lastly, since the outer frame pipe material used for the fence post is as thin as possible for weight reduction, it is not tightened more than necessary, and there is a demand to disperse the load at the mounting portion of the post. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a fence having sufficient reliability even in a case where a single pipe pipe can be freely mounted and a single pipe pipe is frequently attached and detached. Attached to the column, it is attached regardless of the length of the column spacing between adjacent fences, and its mounting workability is good.It does not protrude when the single pipe is removed, and it has various shapes and sizes SUMMARY OF THE INVENTION An object of the present invention is to provide a fence reinforcing structure having a compact configuration capable of coping with a single pipe and having a compact structure capable of easily reinforcing the single pipe without the necessity of firmly constructing the single pipe itself.
