PROBLEM TO BE SOLVED: To ensure an easy and speedy work by forming a part placed on a support beam of only steel bars, disposing a cantilever part and a synthetic floor integrally, and executing the cantileve part and a main body part integrally with the support part by cast-in-place concrete. SOLUTION: A part placed on a suppport beam X is formed by only steel bars, a cantilever part 2 at an end and a main body 3 at a central part are disposed interally with a synthetic floor board. The parts 2, 3 are placed integrally with the support beam X by conncrete 4. Each steel bar 1 is disposed between reinforcement parts Y of the support beam X and a welding metal net is layed on a bottom board, and then a PC concrete board is formed by executing the connection by means of steel bars 1 and bolts 6. The botom board of the cantilever part 2 is formed of RC pannel, the pannel and the steel bar 1 are connected by means of bolt, one end of the RC pannel is locked to the support beam X, and perform suspensionwise installation by adjustment of bolt 6. Accordingly, an easy, safe and speedy work is ensured, thereby reducing the work period and work costs. |
