Description

Известны устройства дл  нат жени  арматуры предварительно напр женных железобетонных изделий с передачей сжимающих усилий на поддон формы, включающие неравноплечие рычаги.Arrangements for tensioning reinforcement of prestressed concrete products are known with transfer of compressive forces to the form pallet, including unequal arms.

Предложенное устройство обеспечивает плавную передачу усилий от арматуры на затвердевший бетон за счет выполнени  рычагов в виде вертикально расположенных коромысел на торцах поддона. Верхний конец каждого рычага снабжен зажимом дл  арматуры (стержневой или пучка высокопрочных проволок), а нижний - гайкой. Гайка навинчиваетс  на конец ст жки, расположенной снизу поддона. Соотношение нижнего и верхнего плеч коромысла больше единицы.The proposed device provides a smooth transfer of forces from the reinforcement to the hardened concrete due to the implementation of levers in the form of vertically arranged rocker arms at the ends of the pallet. The upper end of each lever is provided with a clamp for reinforcement (rod or bundle of high-strength wires), and the lower end with a nut. The nut is screwed onto the end of the strainer located below the pallet. The ratio of the lower and upper shoulders of the rocker arm is greater than one.

На чертеже .изображено предложенное устройство дл  нат жени  арматуры, смонтирова)ное на торце формы.Fig. 1 shows the proposed device for tensioning the reinforcement mounted on the end of the form.

Устройство состоит КЗ рычагов /, зажимов 2, нат жной гайки -3 с самоцентрируюш.ейс  щайбой 4, ст жки 5, поддона 6   напр гаемой арматуры 7. С другой стороны поддона 6 монтируетс  точно такое же устройство.The device consists of short-circuit levers /, clamps 2, tension nut -3 with a self-centering lock 4, clamp 5, pallet 6 of tensioned reinforcement 7. On the other side of pallet 6, exactly the same device is mounted.

Нат жение (напр жение) арматуры 7 осуществл етс  закручиванием гайки 3. Соотношеиие плеч рычагов 1 беретс  таким, чтобы равнодействующа  всех усилий совпадала с центром т жести сечени  поддона 6.The tension (tension) of the reinforcement 7 is carried out by tightening the nut 3. The ratio of the arms of the levers 1 is taken such that the resultant of all the forces coincides with the center of gravity of the section of the pallet 6.

Раскручивание гайки 3 позвол ет плавно передавать усили  от арматуры 7 на затвердевший бетон.Unscrewing the nut 3 allows you to smoothly transfer forces from the reinforcement 7 to the hardened concrete.

Устройство дл  Нат жени  арматуры предварительно напр женных железобетонных изделий с передачей сжимающих усилий, на поддон формы, включающее иеравноплечие рычаги, отличающеес  тем, что, с целью обеспечени  возможности плавной передачи усилий от арматуры на отвердевший бетон, его рычаги выполнены в виде смонтированных на торцах поддона и вертикально расположенных кopo sыceл,A device for tensioning reinforcement of pre-stressed reinforced concrete products with transfer of compressive forces to the form pallet, including levers with leverage, characterized in that, in order to ensure the possibility of smooth transmission of forces from the reinforcement to hardened concrete, its levers are designed as mounted on the ends of the pallet and vertically arranged kopos,
