[Effect of device]

In the invention of claim 1, a metal fitting body A which is a flat metal fitting main plate 1 having a groove-shaped mountain-shaped recess 1b having the same depth as the plate thickness of the bottom portion 7 of the receiving metal fitting C in the middle in the longitudinal direction, And a metal fitting B formed in a U-shape having an opening slightly smaller than the plate thickness of the mounting surface 8a of the structural member 8, one end of the metal fitting B is provided on both sides of the metal fitting main plate 1. By using the mounting bracket for the receiving bracket pivotally mounted 4 on the same plane as the bracket main plate 1, the receiving bracket C can be easily and quickly attached to the structural member 8 such as a cross beam.
Secondly, regardless of skill level, any worker can always fix the receiving metal fitting to the structural member 8 with a constant strength, and thirdly, the mounting for the receiving metal fitting. The components of the metal fitting are pivotally attached to each other, and there is an effect that the components are not lost and safe work can be performed.

These effects will be described in detail. First, the metal fitting main plate 1 of the metal fitting body A is placed on the bottom portion 7 of the receiving metal fitting C from above, and the mounting surface 8a of the structural member 8 is simply closed by closing the locking metal fittings B and B. Can be installed. Therefore, there are many work processes in conventional welding work. Specifically, a welding machine is set at the site, the actual welding work is performed, and then the slag at the welding location is dropped, and the rust-preventive paint is applied there. There is a need for work procedures such as painting, welding work below 0 degrees Celsius or in the presence of wind, etc., because the welding strength will not be sufficient, and it will not be possible to work, and electric shock etc. on rainy days However, in the present invention, the construction can be carried out regardless of such weather conditions and the above-mentioned drawbacks can be solved.

Further, unlike the means of fixing with fixing tools such as bolts and nuts, the fixing of the receiving metal fitting is completed only by closing the locking metal fitting B so that it fits in the metal fitting main plate 1, and the work can be done instantly and quickly. It will be a simple task.

Next, the fixing of the receiving metal C to the structural member 8 is performed by the locking metal fittings B and B pivotally mounted 4,4 on the metal fitting body A, and each worker like fixing means by welding. There is no difference in finish due to the skill of the above, and only the locking metal fitting B is closed with respect to the metal fitting main plate 1 which covers the bottom portion 7 of the receiving metal fitting C placed on the mounting surface 8a of the structural member 8. Regardless of which worker is working, it is possible to always secure a constant mounting strength.

Next, the mounting metal fitting for the metal fitting of the present invention comprises a metal fitting body A which is the metal fitting main plate 1 and a locking metal fitting B. The locking metal fitting B is pivotally attached 4 to the metal fitting body A. The locking metal fitting B is always integrated. Therefore, the metal fitting body A
Since the locking metal fitting B is not separated, there is no inconvenience that the locking metal fitting B is lost from the metal fitting body A during work.
Furthermore, since fasteners such as bolts and nuts are also required, it is not necessary for the worker to pay attention so as not to lose the parts, and it is possible to concentrate on the mounting work of the receiving metal fittings, which in turn realizes safe work.

In particular, since there is a groove-shaped mountain-shaped recess 1b having the same depth as the plate thickness of the bottom 7 of the receiving metal fitting C, the metal fitting main plate 1 is fixed by rotating the locking metal fitting B. At the same time, there is an advantage that the bottom portion 7 of the receiving fitting C can be reliably fixed in the chevron-shaped recess 1b.

Next, in the invention of claim 2, the clamp fixing pieces 1a are formed on both sides in the longitudinal direction of the metal fitting main plate 1 in the structure of claim 1, and when the locking metal fitting B is closed, the upper part 2 is clamped by the clamp fixing pieces 1a and the metal fitting. When the locking metal fitting B is closed so as to fit in the metal fitting body A by being clamped and fixed between the main plate 1 and the main plate 1, the upper part 2 of the locking metal fitting B is clamped by the clamping fixing piece 1a and the metal fitting main plate 1. The locking metal fitting B, which is clamped and fixed on the main plate 1 and is once closed,
It is possible to prevent the metal main plate 1 from opening outward, that is, to prevent loosening due to vibrations such as an earthquake or the like, or distortion of the structural material 8 or the like, and it is possible to suitably perform safety management.

Next, in the invention of claim 3, a sandwich bending portion 5 having an opening slightly smaller than the plate thickness of the mounting surface 8a of the structural member 8 is formed on one side in the longitudinal direction of the metal fitting main plate 1, and the other side is formed. The metal fitting main body A having a groove-shaped mountain-shaped recess 1b having the same depth as the thickness of the bottom portion 7 of the receiving metal fitting C, and the plate thickness of the mounting surface 8a of the structural member 8 in the middle thereof. And a metal fitting B formed in a U shape having a slightly small opening, and one end of the metal fitting B is rotated to the other side of the metal fitting main plate 1 on the same plane as the metal fitting main plate 1. By using the mounting bracket for the receiving bracket which is freely pivotally attached 4, firstly, the mounting bracket for the receiving bracket can be mounted instantaneously, and secondly, the receiving bracket having an extremely simple structure can be obtained. That is, since the sandwiching bent portion 5 is formed on one side of the metal fitting main plate 1, the metal fitting main plate 1 is mounted on the mounting surface 8a while sandwiching and fixing the sandwiching bent portion 5 to one end of the mounting surface 8a of the structural member 8. After mounting, the locking metal fitting B can be fixed by simply closing it so as to fit in the metal fitting main plate 1. This is because the locking metal fitting B is attached from one edge of the mounting surface 8a of the structural member 8 on which the receiving metal fitting C is mounted. It can be completed by simply closing, and the burden on workers can be reduced significantly.

Next, the holding and bending portion 5 can be easily manufactured by simply bending one end of the metal fitting main plate 1 in the width direction toward the center side of the metal fitting main plate 1 and can be provided at a low price.
