  • Apparatus for prestressing concrete floor of inclined shaft wall
    Patent number: 10612241
    Abstract: An apparatus for prestressing a concrete floor of an inclined shaft wall includes two end bearing components, a corrugated pipe, a tension bearing rod piece and two anchor heads. The tension bearing rod piece is composed of a left tension bearing rod, a right tension bearing rod, and a loading mechanism. The left tension bearing rod and the right tension bearing rod, are connected integratedly by the loading mechanism, and the tension bearing rod piece passes through the corrugated pipe. The two end bearing components are respectively arranged at the left and right ends of the tension bearing rod piece in a sleeving manner. The two anchor heads respectively lock the left and right end bearing components. Before pouring of the floor of the shaft wall, the loading apparatus is pre-buried. After the strength of floor concrete increases to certain extent, a transverse prepressing stress is applied to the floor concrete through the loading mechanism.
