Full prestress tension plate external member
The invention discloses a full prestress tension plate external member which comprises a tension plate. The tension plate is provided with vertical strengthening ribs, cross strengthening ribs, inclined strengthening ribs, a screw hole and through holes. The screw hole is formed in the center of the tension plate, the through holes are formed in the periphery of the tension plate at equal distances, and steps are arranged in the through holes. The vertical strengthening ribs and the cross strengthening ribs are arranged on the peripheries of the through holes, the inclined strengthening ribs are arranged between the screw hole and the vertical strengthening ribs and between the screw hole and the cross strengthening ribs, and a guide sleeve is arranged in each through hole. The guide sleeves and the through holes are connected in clearance fit, the guide sleeves are detachable and can be replaced in time after being abraded, so that the production cost is saved, and the strength and the precision of a prefabricated pile are improved. In addition, the integral forming manufacturing mode is adopted for the tension plate and a tail tension plate, the vertical strengthening ribs, the cross strengthening ribs and the inclined strengthening ribs are arranged on the tension plate and the tail tension plate, the tensile strength of the tension plate and the tail tension plate is greatly improved, the tension plate and the tail tension plate are not likely to deform in the tension process, and the bearing force is higher.
