    • PURPOSE: To facilitate the transfer of a conveying pipe, reduce the damage of reinforcements, and improve the working efficiency by providing a sled-shaped base frame having a floor plate whose edge is warped upward and a bendable pipe provided on the upper part of a frame base in a concrete placing device. CONSTITUTION: A sled-shaped frame base is constituted of the upper supporting frame base 1 supporting the upper part of a steel pipe 3 and the lower supporting frame base 2 supporting the lower part of the pipe. Steel frames 12, 22 are assembled to form a triangle on the upper part of the bottom plate 21 whose edge is warped upward, and clamps 14, 23 are provided to fix the steel pipe 3. A plurality of U-shaped tubular bodies are connected to rotatable connection parts 31 alternataly jointed to form a corrugated shape. The ridge steel pipes 3 and the valley steel pipes 3 are formed so as to be independently and horizontally rotatable around the vertical axis A. A rubber flexible hose 6 is attached to the tip of the steel pipe 3 to pull and shift the pipe 3 to an arbitrary position and place concrete. In this way, the working efficiency can be improved because transfer works are not required.
