Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary material connecting metal fitting for connecting temporary materials such as pipes to each other so as to construct a scaffolding at a construction site. It eliminates the inconvenience of having to prepare multiple types according to the application, and enables the use of one type to deal with the tightening of all temporary materials, and eliminates so-called rattling even in the case of a freely rotatable so-called clamp. The present invention relates to a temporary material binding metal fitting that can maintain excellent strength.

[0002]

2. Description of the Related Art Conventionally, temporary materials such as a single pipe for constructing a scaffold at a construction site and a generally U-shaped pipe called a bitty are tightly connected to each other and connected. As a temporary material binding metal fitting called a clamp to be installed, the orientations of the two binding members are set to 90 in order to fasten the orthogonal temporary materials.
Orthogonal type clamps that have been re-fixed and fixed, two types of free-type clamps in which two binding members are rotatably engaged to bind braces, and the inside diameter of the binding members is 48.6 mm.
There are two types, one for the single pipe that is adapted to the pipe of the above, and one for the vity that is adapted to the vity with an outer diameter of 42.7 mm, and the inside diameter of the binding member for the same diameter that is dedicated for the single pipe or for the vity, and the inside diameter of the binding member. There are two types for different diameters that can be adapted for both single pipe and bite.

[0003]

However, since there are many kinds of conventional temporary material binding metal fittings, as described above, it is very troublesome to separately order and manage various types of temporary material binding metal fittings. In addition, it is extremely difficult to sort and store various types of temporary material binding metal fittings in a narrow place at a high place such as a scaffolding at a construction site, and therefore, a temporary material binding metal fitting of a desired type is ordered each time. The work efficiency of scaffolding construction was inferior, and the work with safety problem of tightly connecting the orthogonal parts with a flexible clamp, which is inferior in strength to the orthogonal clamp, was sometimes forced. Further, in a free-type clamp for tightly connecting a brace or the like, a connecting member for connecting two binding members is a cylindrical body in which a notched hole portion is loosely fitted on one side surface thereof and is caulked. Since the two tightening members each have a gap with respect to the cylindrical body, even when the temporary member is tightened, the two tightening members cause a slight movement called backlash due to the gap, which ensures the reliability. It was not possible to maintain a proper engagement state. Therefore, in the present invention,
The inconvenience caused by the existence of multiple types of conventional temporary material binding metal fittings is eliminated, and it is possible to handle all types of temporary material binding with one type, and a binding member that can be rotated like a universal clamp. It is an object of the present invention to provide a temporary material binding metal fitting that can maintain excellent strength without mutual slight movement.
