(Effect of the Invention) The present invention achieves the original purpose by being configured as described above.

That is, according to claim 1, in the construction using the floorboard plate P in which the I-shaped protrusion P1 is formed on the lower surface of the plate, the suspension rod member Q such as a suspension bolt is suspended regardless of the concrete pouring time. It can be detachably supported on the lower surface of the rod member Q.

Therefore, like the conventional construction using the deck plate, it is freed from the troublesome work such as the installation work of the insert before the concrete is placed.

Moreover, the reinforcing piece P is formed by projecting from the lower end of the I-shaped projection P1 on both sides of the longitudinal section of the ridge and extending along the longitudinal direction of the ridge.
Since the supporting metal fittings themselves are attached by the pair of gripping bodies 1 that grip the two width-length ends, after the concrete is placed,
Even if the mounting position of the hanging rod member is changed, the mounting position of the support fitting itself can be changed very easily.

Further, since the grasping body 1 and the connecting body 2 are swingably connected by the tightening bolts 20, there is an advantage that the supporting angle of the suspension rod member Q can be arbitrarily set.

Further, according to claim 2, the connecting nut 10 placed on the placing portion 4 of the connecting body 2 has a pair of locking holes 7 formed in the locking portion 5.
Further, since the opposite corners on the outside thereof are locked, it is possible to prevent the connecting nut 10 from falling off when mounting the metal fitting of the present invention. Therefore, the installation work at a high place becomes very easy. In addition, the connection nut 10 is the connection body 2
Since it is fixed inside, when the suspension rod member Q such as the suspension bolt is screwed to the connection nut 10, it can be easily attached with one hand, and the work efficiency is high. Further, at this time, even if the connecting nut 10 is disengaged from the locking hole 7, the connecting nut 10 is sandwiched between the locking portions 5, so that idling can be prevented.

As described above, according to the present invention, in the construction using the I-type deck plate for the floor plate, it can be mounted at any time regardless of the concrete pouring time, and the mounting work is easy, and the suspension rod member mounting is possible. Even if the position is changed later, it can be coped with very easily, and in addition, various practically useful effects can be obtained such that the supporting angle of the hanging rod member Q can be arbitrarily set.
