Abstract
The utility model discloses a novel tension board assembly. The novel tension board assembly adapts to production of high-strength concrete prestressed hollow square piles and high-strength concrete prestressed pipe piles. The novel tension board assembly is composed of a tension board, a stressed joint and a tension screw. The tension board is drilled with tension board bolt holes and fixed on a precast member through tension board bolts, a boss is arranged in the center of the tension board, and the protruding part is arranged on the opposite side of the precast member. A cylindrical counter bore not penetrating is arranged in the tension board along the direction of a side on which a precast member is arranged, and a plurality of tension board protruded edges are evenly arranged between the counter bore and the surface of the boss along the circumferential direction. Compared with a traditional tension board, the novel tension board assembly has the advantages that the tension board can be separated from the stressed joint quickly, the tension board bolts can be unscrewed conveniently, manual labor of workers is reduced, and production efficiency of concrete precast piles is improved. In addition, the novel tension board assembly is suitable for automatic production lines and common production lines.
