BRANCHED PIPING STRUCTURE

Japanese Patent JP2016196736

A

PROBLEM TO BE SOLVED: To provide a branched piping structure that suppresses separation among materials of concrete, while suppressing wear inside the piping at the branched portion caused by pumped concrete.SOLUTION: A branched piping structure S has a bottom part of an upper pipe 1 connected with a top part of a first lower pipe 21 with a shaft center of the pipes deviated from each other, and the bottom part of the upper pipe 1 connected with a top part of a second lower pipe 22 with a shaft center of the pipes deviated from each other. A communicating port 6 that communicates an inner space of the upper pipe 1 with an inner space of the first lower pipe 21 is formed at a part where the bottom part of the upper pipe 1 and the top part of the first lower pipe 21 are overlapped. Furthermore, the communicating port 6 that communicates the inner space of the upper pipe 1 with an inner space of the second lower pipe 22 is formed at a part where the bottom part of the upper pipe 1 and the top part of the second lower pipe 22 are overlapped.SELECTED DRAWING: Figure 2
