用する。 Flat slab 2 has a reinforced concrete structure.
Depending on the case, an unbonded PC steel wire 4 is buried inside the wire. The capital 3 has approximately 1.5 to 2.5 m on a side and a thickness of approximately 0.5 to 20 mm, with the pillar 1 penetrating through the center of the capital 3 and the pillar 11.
is fixed by welding, etc. The bottom surface of this capital 3 is made to be at the same height as the bottom surface of the flat slab 2. FIG. 4 shows the case where the capital 3 is box-shaped, the inside of the capital 3 is filled with concrete, and the thickness of the flat slab 2 in that part is increased. 5 to 8 show reinforcing means for the capital portion. In FIGS. 5 and 6, a large number of studs 5 are welded and protruded on a steel plate constituting the capital 3, and the studs 5 are connected in a lattice-like manner with reinforcing bars 6. In Figures 7 and 8, stirrup reinforcements 7 are arranged in a lattice pattern, and the lower part of the stirrup reinforcements 7 is fixed by welding or the like, and these studs 5 or stirrup reinforcements 7 integrate and reinforce the capital 3 and the flat slab 2. Acts as an anchor muscle.

Furthermore, even when making that part thick like a conventional capital, a flange formed around the capital can be used so that only a slight thick wall is required.
In this case, by providing anchor bars protruding from the steel plate that will become the capital, the function as a capital can be made more reliable.
なおこの構造は柱を細い断面の鉄骨構造とする
ことが容易であり、それによつてスペースの有効
利用が計れる。 Furthermore, in this structure, it is easy to make the columns a steel structure with a narrow cross section, which allows for effective use of space.
