PROBLEM TO BE SOLVED: To dispense with a form supporting scaffold to reduce the manpower and cost by fixing a form member to a concrete plate member to block a clearance part, and placing concrete to connect adjacent plate members. SOLUTION: In the connecting part of concrete plate members 13, 15 constituting a floor board, a flat form member 21 of stainless steel is fixed to the bottom of the plate member 13 by a bolt 23. The plate members 13, 15 are arranged, a clearance 17 is blocked by the form member 21, a reinforcement 41 consisting of a longitudinal member, a binding member and a leg member is arranged in the clearance 17, and concrete is placed and hardened as a connecting material 31 to connect the plate members 13, 15. An unequal angle steel may be fixed to the end surface lower parts of the plate members 13, 15 instead of the flat form member 21, so that the flanges of the unequal angle steel are lapped to block the clearance 17. According to this, the scaffold for supporting the form member 21 is dispensed with, and the manpower and cost required for the assembling and disassembling of the scaffold can be reduced.
