However, before the upper member 11 is damed, the upper opening 20 of the upper member 13 is sealed via a gasket 19 in the upper part of the upper part #13, which is drilled at the site or in a factory for mass production. A lid member 12, which can be appropriately locked by a hook 21, is attached to the lid member 12 by a hinge 22 so as to be openable and closable.

Above, the upper and lower members 11, 13. The lid member 12 is usually made of glass reinforced concrete (GRC) lζ from the viewpoints of compatibility with slab materials, strength, and prevention of damage during lightweight drilling, but is not limited to this, and is made of glass reinforced concrete (GRC) due to cost, weight, FRP was chosen in consideration of its durability, waterproofness, and compatibility as a system with other materials.

Cast iron, stainless steel, synthetic resin, or a composite material thereof is used as appropriate.Next, in order to embed the embedding unit A configured as above in the rooftop slab 2a, as shown in FIG.
ζ First, the upper member 11 is placed in a predetermined position on the formwork 31 for pouring the rooftop slab 2a, but in order to position the lower member 11, it is fixed to the formwork 31 by the poles 14b and the necessary In order to improve the integrity with the slab 2a, the outer end of the iron bar Jla with the pipe locking fitting 35wR is welded to the reinforcing bar 32 of the indoor slab 2a. Next, concrete for slab 2& is poured. After this concrete hardens and the roof slab 2a is formed, the formwork 31 is removed as shown in FIG. The lower member 11 has a convex portion 15
Then, the inner plate of the rooftop slab 2a is firmly fixed by welding the reinforcing bars 32 and the iron rods 11a.
