Abstract
PURPOSE: To easily perform the construction of prestressed concrete pile having high strength by a method in which a bar-like tension casing whose periphery is provided with the main iron bars is inserted into a pile pit, concrete is placed into the pit, and a tensile force is given to the main iron bars while holding the said casing.
CONSTITUTION: In the first place, pile pits 2 with given diameter and length are excavated in given places under the ground 1, and an iron bar cage 5 formed by connecting upper and lower iron bar cages 5a and 5b by a connecting member 8 is inserted into the pit 2. In this case, the iron bar cage 5a is formed by thrusting the main iron bars 3 into each of coupling ribs 13 and 14 plurally, radially, and projecttionally provided at the upper and lower ends of a bar-like tension casing 11 provided at the center and then fixing them to the rib 14. Then, concrete is placed into the pit 2, the casing 11 is held, a tension device 12 is connected to the upper end of the main iron bars 3, and the main iron bars 3 are pulled up. After the concrete 10 has set, tensile force is released to complete the prestressed pile construction work.
