[0021]

According to the slab structure of the present invention, the joint joints 4a formed on the long sides of the ALC plates 1 arranged in parallel have a joint width at a position away from the corner 3 of the ALC plate 1. A cutting hole 5 having a larger width and not penetrating to the back surface is formed so as to straddle, and a torsion opening portion 8b is formed on a side surface portion of which the head annular portion 8a is twisted so that the long reinforcing bar 9 can be fitted. A screw 8 having an annular portion on the head having a threaded portion at the lower end is disposed at the corner 3 and the ALC
A long joint reinforcing bar 9 is arranged over the entire length of the connection joint portion 4a along the long side of the plate 1, and the long joint reinforcing bar 9 is connected via a screw 8 having an annular portion to the head. Since the mortar 14 is fixed to the beam 2 and the long side connection joints 4a, the short side connection joints 4 and the cutting holes 5 are filled with mortar 14, the entire slab is formed as a single plate. be able to. Therefore, the horizontal rigidity of the entire slab can be significantly increased.

On the other hand, as described in the present invention, the ALC plate 1
Even if a long joint reinforcing bar 9 (that is, it is necessary to use a long reinforcing bar that is at least longer than the length of the ALC plate 1) is disposed over the entire length of the connection joint portion 4a along the long side of A
It is formed at a position apart from the corner 3 of the LC plate 1 and straddles the connection joint 4a with a width larger than the width of the connection joint 4a. When the cutting hole 5 that does not penetrate is not drilled, the portion of the ALC plate present below the joint joint portion 4a is a portion where the reinforcing bar buried in the ALC plate 1 does not exist, so that the in-plane horizontal When a strong force acts, the lower part of the joint joint 4a of the ALC plate 1 together with the mortar filled in the joint joint 4a is peeled off from the ALC plate 1, and surprisingly, the ALC plate 1 Each ALC plate 1 is scattered, and the horizontal rigidity is extremely low.

Further, the screw 8 having an annular portion on the head used in the present invention is such that the annular portion 8a of the head is twisted laterally, a twisted opening 8b is formed on the side surface thereof, and a screwed portion is formed at the lower end. 8, the long reinforcing bar 9 extending over the entire length of the connection joint portion 4a along the long side of the ALC plate 1 is formed as shown in FIG.
As shown in FIG. 9B, FIG. 9B, and FIG. 10B, the screw 8 can be easily inserted into the torsion opening 8b of the screw 8 having the annular portion on the head turned sideways. In this state, twisting is performed using the lower screw-in portion, and FIG. 8 (A), FIG. 9 (A), FIG.
As shown in (A), the long reinforcing bar 9 extending over the entire length of the joint joint 4a along the long side is joined to the head annular portion 8.
a can be reliably held. As described above, in the present invention, since the screw 8 having the annular portion at the head of the above-described structure is used, a long reinforcing bar extending over the entire length of the connection joint portion 4a along the long side of the ALC plate 1 is used. There are many effects such as the work for fixing the 9 to the beam 2 can be remarkably improved.
