Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be easily and quickly mounted on a structural member such as a purlin, a furring strip, a lateral beam, etc., particularly a lip grooved steel, an I-shaped steel, an H-shaped steel, a channel steel, etc. The present invention relates to a bracket that can maintain an extremely strong mounting condition against any external force.

[0002]

2. Description of the Related Art Conventionally, welding has been used as a method of attaching brackets to structural materials such as purlins and furring strips using various shaped steel materials such as lip channel steel, I-shaped steel, H-shaped steel and channel steel. Although the means for attachment is taken, welding in the field has various problems in terms of safety, dispersion of mechanical strength of welding, repair after welding, and the like. Therefore, there are many construction methods that can be attached without welding. In the conventional type, the flanges of H steel are sandwiched on both sides in the width direction and the bracket is fixed to a structural material such as H steel.

[0003]

However, in the case of the conventional metal fittings made by the non-welding method, the grip width varies depending on the width of the flange of the lip groove section steel, I section steel, H section steel, etc. It is necessary to use different types of. In addition to these, various types have been developed as boltless means or non-welding means, but the mounting strength is actually expected even though the structure of the bracket itself becomes complicated and expensive. In addition, there are various problems in that the fixing work such as bolts and nuts or the fixing means such as welding can be carried out easily and quickly even in the mounting work.

[0004]

Therefore, as a result of earnest studies to solve the above-mentioned problems, the inventor has found that the present invention provides a bracket main body having legs from both sides in the width direction of the top and a receiving plate. Side plates are formed on both sides in the width direction of the base plate, and the side plate part is formed of a pedestal having a jaw portion close to the lower end of the leg part, and a fixing wedge member. A lip is formed by pivotally supporting both side plate parts, the receiving metal body being rotatable on the pedestal, and the fixing wedge member being a receiving metal insertable between the receiving metal body and the receiving plate part of the pedestal. Channel steel,
It can be firmly attached to structural materials such as H-section steel and I-section steel, and its mounting work can be done easily and quickly.
The work efficiency is improved and the above problems are solved.
