PROBLEM TO BE SOLVED: To provide a disassemblable connection portion between a floor slab and a beam, which can be disassembled after completion thereof in the construction field, takes countermeasures against water leakage and sound leakage in a floor slab service condition, and eliminates the risk of detachment of a filler from the connection portion in the floor slab service condition, to thereby contribute to improved disassembling efficiency. SOLUTION: The connection portion is formed of a beam member 1 having a flange 1a and the floor slabs 2 supported by the beam member 1. Each floor slab 2 has a notch 2a formed in an end face close to the beam member 1 except for a joint portion 2b being left on a lower side of the end face, in a manner extending in a thickness direction from an upper surface of the floor slab such that a width of the notch extends from the upper surface to a lower surface. Then the floor slabs 2 thus formed are mounted on the beam member 1 so as to be opposed to each other, and connected to the beam member 1 by bolts 3 each penetrating the flange 1a and the joint portion 2b. Further a waterproof separating material 5 is bonded to a surface of a void defined by the notch 2a, and a filler 6 is filled onto the waterproof separating material 5. COPYRIGHT: (C)2008,JPO&INPIT
