Inter-beam steering gear of broken line pre-tensioning method precast concrete beam and construction method
The invention discloses an inter-beam steering gear of a broken line pre-tensioning method prefabricated concrete beam and a construction method. A bottom frame of the inter-beam steering gear comprises a concrete base and a limiting cylinder arranged on the concrete base, a lifting assembly comprises a steering column, a stiffening supporting plate and a jack, an inner side edge of the stiffeningsupporting plate is fixed to a peripheral wall of the steering column, the jack is arranged between the concrete base and the stiffening supporting plate, a lower portion of the steering column is sleeved with a limiting cylinder, the height of the steering column is adjusted through the jack, a guide assembly comprises idler wheels, pin shafts and nuts, and the idler wheels are arranged on the steering column at equal intervals through the pin shafts and the nuts. The steering gear is advantaged in that the steering column is jacked in place through the jack, steering of a broken line prestressed tendon is achieved, releasing and stretching of the broken line prestressed tendon are achieved through force unloading of the jack, the inter-beam steering gear is light in structure, simple inconstruction method and remarkable in effect, adjustability is achieved, and safety of prefabricating construction is improved; on the other hand, durability is high, the service life is long, and reutilization is achieved.
本发明公开了一种折线先张法预制混凝土梁梁间转向器及施工方法，梁间转向器的底架包括混凝土基座和设置在混凝土基座上的限位筒；升降组件包括转向柱、加劲支撑板和千斤顶，加劲支撑板的内侧边固定至转向柱的外周壁上，千斤顶设置在混凝土基座和加劲支撑板之间，转向柱的下部套接在限位筒内，通过千斤顶实现转向柱的高度调节；导向组件包括滚轮、销轴和螺母，滚轮通过销轴和螺母等间隔的设置在转向柱上。通过千斤顶顶升转向柱就位，实现折线预应力筋的转向，通过千斤顶卸力，实现折线预应力筋的放张，该梁间转向器结构轻巧，施工方法简单，效果显著，具备可调节性，提高了预制施工的安全性；另一方面，其耐久性强，寿命长，可重复利用。
