Description
жении, на фиг, 4 показано взаимное расположение стержней и гидроципиндров,Fig. 4 shows the relative position of the rods and hydraulic chippers,
Опалубка содержит опорную раму 1, шарнирно соединенные между собой секции 2 опалубки; стержни 3, шарнирно соединенные с секци ми; стержни 4, шарнирно соединенные с опорной рамой и винтовой муфтой 5, вмонтированной в стержень 4, силовые гидроцилиндры 6 и шарниры, соедин ющие стержни и гидродомкраты 7.The formwork contains a support frame 1, sections of formwork 2 pivotally interconnected; rods 3 pivotally connected to sections; the rods 4 pivotally connected to the support frame and the screw coupling 5 mounted in the rod 4, the power cylinders 6 and the hinges connecting the rods and hydraulic jacks 7.
Дл облегчени процесса складывани секций опалубки к одной из секций шарнирно присоединен клапан 8,In order to facilitate the folding of the formwork sections, a valve 8 is hingedly attached to one of the sections,
Опалубка работает следующим образомThe formwork works as follows.
По окончании очередного цикла бетони- ровани клапан 8 откидываетс к раме опублики, облегча складывание секций, си ловые гидроцилиндры 6, перемеща шарнй ры, соедин ющие стержни 3 и 4, заставл ют секции опалубки 2 оторватьс от бетонной обделки, и при установке опалубки в рабочее положение силовые гидроцилиндры 6 перемещают шарниры, соедин югш-1е стержни 3 и 4 до тех пор, пока оси стержней 3 и 4 не окажутс на одной пр мой, Штоки гидроцнлиндров при этом должны находитьс в крайнем положении.At the end of the next cycle of concreting, the valve 8 leans back to the frame of the publication, facilitating the folding of the sections, the force hydraulic cylinders 6, moving the hinges connecting the rods 3 and 4, cause the sections of the formwork 2 to detach from the concrete lining, and when installing the formwork The position of the power cylinders 6 moves the hinges, connecting the first-1e rods 3 and 4 until the axes of the rods 3 and 4 are on the same straight line. The rods of the hydraulic cylinders must be in the extreme position.
Поскольку оси стержней 3 и 4 наход тс на одной пр мой, нагрузка от бетонной смеси на гидроцилиндры не передаетс , что Since the axes of the rods 3 and 4 are on the same straight line, the load from the concrete mixture on the hydraulic cylinders is not transmitted that

обеспечивает надежность работы всего устройства .ensures the reliability of the entire device.
Кроме того, не требуетс производить регулировку положени секций опалубки перед каждой установкой опалубки. Первоначальна установка положени секций производитс винтовьпч 1и муфтами 5.In addition, it is not necessary to adjust the position of the formwork sections before each installation of the formwork. The initial installation of the position of the sections is done by screwing 1 and clutches 5.
