Prestressed spun high strength concrete pile for reinforcement of Tensile material at Outer Circumference of Pile

摘要

The subject innovation is in the tension member and the concrete pile to synthesize,; Wherein the tension member (1) is a curved waveform is formed on the outer peripheral surface, and filled with the tension member (1) of concrete (2) inside the formed through-hole in the longitudinal direction of the pile of the spiral shape, the interior of the concrete of the pile outer surface, it characterized in that the PC steel bar (3) was added to the tension reinforcement by a reinforcement (6) settled in the circumferential array of spaced tension members are prestressed reinforcement relates to a pile.; Thus, the present design is the effect of the concrete pile and the steel pipe pile by introducing a prestress due to synthesis by filling the concrete using the centrifugal force, after fixing a PC steel bar reinforcement by reinforcement of a spiral form on tension member inside the bending wave formed on the outer peripheral surface because it has at the same time using the high compressibility of the pretension centrifugal prestressed concrete piles and the centrifugal force and the pretension can reinforce a low tensile strength and low brittleness and a tensile force of the concrete pile of prestressed concrete piles as steel pipe piles for wrapping the outer circumferential surface.; And then fixing a PC steel bar reinforcement in a helical reinforcement inside the tension member is bent waveform formed on the outer peripheral surface by using the centrifugal force to fill the concrete by combining the tension members and a PC steel bar and the concrete, the external reinforcement form the waveform of the curved form because the adhesion area of ​​the concrete and the tension members wide stable frictional force between the soil greatly enhance the frictional force of the pile is, it is the shape of the tension member is formed in a waveform of a serpentine because the effect of the strength of the tension member increases the economic advantages would be used, since the steel pipe is steel pipe thickness thinner than the ready-made composite pile.
