摘要： PROBLEM TO BE SOLVED: To provide a joining tool capable of smoothly joining mutual precast concrete members; and a forming method for a closed conduit or an open conduit.
SOLUTION: This joining tool has a joining cylinder 10 having a bottom part side diametrally expanded part 16 and embedded in the precast concrete members 2A and 2B so that the tip side is opened on an end surface of the respective precast concrete members 2A and 2B, a cylindrical joining bar 11 engaging with the joining cylinder 10 by inserting both end parts into the respective joining cylinders 10 in a state of expanding a diameter along the bottom part side diametrally expanded part 16, and a truncated cone-shaped expansion member 12 inserted into both end parts of the joining bar 11 so as to diametrally expand both end parts. A columnar part 21 extending in the shaft direction is formed in a tip side part of the expansion member 12. A plurality of projection parts 22 are formed on an outer peripheral surface of the columnar part 21. The columnar part 21 contacts with an inner peripheral surface of the joining part 11 via the projection parts 22.

摘要： PROBLEM TO BE SOLVED: To provide a precast box culvert that can prevent a clearance formed between concrete and the bottom face of the precast box culvert. SOLUTION: The bottom face 19 of this precast box culvert 1 with concrete C placed around to form a culvert, is formed in downward projecting shape. Air bubbles K colliding with the bottom face 19 can thereby escape into the atmosphere to prevent a clearance formed between the bottom face 19 and concrete C. COPYRIGHT: (C)2003,JPO
