DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar material used for cross-fixing an upper bar material to a lower bar material, for example, by mounting a bar material for holding a fire extinguishing water pipe on a bar material of a ceiling base frame. The present invention relates to an anti-vibration bracket.

[0002]

2. Description of the Related Art For example, a bar-fixing anti-shake fitting of this type includes a horizontal projection at an upper end protruding toward one side, a bar-engaging portion at a lower end, and a pair of opposed members in the width direction connecting these. A single bracket member having a downward opening disposed between the walls, having a horizontal U-shaped side with a screw hole formed in the horizontal projection, and a fastening bolt screwed into the screw hole. The bar material engaging portion is used for engaging the upper end of the upper and lower bar material, and the tightening bolt is used for pushing down the upper bar material of the upper and lower bar material which is disposed through the opening. When a bar material for holding a fire extinguishing water supply pipe is erected and fixed to the bar material of the ceiling base frame, for example, a C-shaped channel material is used for the lower bar material,
Braille or C-shaped channel material is used for the upper bar material.

[0003]

In this case, since the metal member is a single member, there is an advantage that the vibration damper can be easily fixed by reducing the cost of the vibration damper. There is a possibility that the bar material fixing function as the anti-vibration bracket may be damaged or lost due to detachment or further dropping.

That is, the relationship between the metal member and the upper and lower bar material is such that the upper bar material penetrates the opening when the tightening bolt is pressed down on the upper bar material, while the lower bar material is pressed. Since the bar material engaging portion is engaged with the upper end, the bar material engaging portion of the lower bar material such as the C-shaped channel material is engaged with the horizontal fin-shaped ridge. Therefore, even if the upper bar does not come off first, if an external force is applied to the metal fittings or if the upper and lower bars exhibit different horizontal movements, It is not possible to maintain the hooking engagement state by the bar material engaging portion, and eventually the metal member may be detached from the lower bar material and may be further dropped. The function of material fixing is lost or lost, Over material leads to a non-fixed state.

[0005] In particular, after the bar material is fixed by using this kind of anti-vibration fitting, other work and work such as electrical wiring work and maintenance and inspection after the installation of the fire extinguishing water pipe may be performed. An external force may be applied to the worker's body or feet by touching the anti-vibration brackets, and when an earthquake occurs, the upper and lower bars may move differently in the horizontal direction due to the vibration of the building. , Rocking between the upper and lower bar materials and the resulting displacement may occur.
In such a case, it is particularly supposed that the function is directly affected by the bar material fixing function of the anti-vibration fitting.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a solution to the problem is to fix the bar material as easily as possible and to ensure that the bar material does not come off for a long period of time. It is an object of the present invention to provide a bar material fixing anti-shake fitting which can maintain and secure the material.
