but is high to the specification, plete by the skilled worker, can ensure the security. Р2)Plants the muscle technology РIt is one item is simple and direct to the concrete structure, the effective connection and the anchor technology; May implant the ordinary steel bar, may also implant the bolt type anchor muscle; Has widely applied in had building's reinforcement improvement project, for example: In the construction leaks buries the steel bar or the steel bar deviation designs the position the recovery, ponent increases the section reinforcement to make up the muscle, the superstructure expands cross, goes against rises to Liang, column's lengthening by joining, the house superimposed layer terminal and the high-rise construction addition shearing force wall plants the muscle and so on.
