大多数水泥制品厂和混凝土构件厂,生产先张法预应力混凝土构件时,张拉钢丝的夹具一般都是采用圆锥齿板夹具、圆锥三槽式夹具(即BJ_3、BJ_4和CJ_5)和钢筋扣。我厂主要生产预应力桁条和多孔板等构件,在生产实践中,我们从构件外形特征、控制应力的大小、钢丝的规格和数量等因素考虑,将锥形夹具改革成了组合式夹具。
In most cement products and concrete component plants, when pretensioned prestressed concrete components are produced, the fixtures for the tensioned steel wire are generally made of conical gear plate fixtures, conical three-slot fixtures (ie, BJ_3, BJ_4, and CJ_5) and steel bars. . Our factory mainly produces components such as prestressed purlins and perforated plates. In the production practice, we consider the factors such as the shape of the components, the magnitude of the stress control, the specification and quantity of the steel wire, and the conical fixture is reformed into a modular fixture.
