Description
(54) НАТЯЖНОЕ УСТРОЙСТВО ПРЕИМУЩЕСТВЕННО(54) TENSION DEVICE FORMERLY
ДЛЯ ПРЕДВАРИТЕЛЬНОГО НАПРЯЖЕНИЯ ШПРЕНГЕЛЬНЫХFOR PRELIMINARY VOLTAGE OF SPRENGEL
БАЛОК БОЛЬШЕПРОЛЕТНЫХ ПОКРЫТИЙBALOK MOLKHOLECHOLETNY KODYTI
другими концами к предварительно напр женной балке жесткости 5, а концы ст гиваемого элемента жестко присоединены к рычагам 1 и после предварительного напр жени замыкаютс элементом 6.the other ends to the prestressed stiffening beam 5, and the ends of the element to be pulled are rigidly connected to the levers 1 and, after prestressing, are closed by the element 6.
Это позвол ет фиксировать устройство относительно преднапр гаемой конструкции путем непосредственного креплени спаренных рычагов к балке жесткости. Сами же спаренные рычаги также позвол ют увеличить силу нат жени относительно усили , развиваемого домкратами.This makes it possible to fix the device relative to the prestressed structure by directly attaching the paired levers to the stiffening beam. The coupled levers themselves also allow the tension force to be increased relative to the force developed by the jacks.
Предлагаемое устройство позвол ет также осуществить предварительное напр жение большепролетных т желых конструкций непосредственно при их монтаже с помощью обычных ст жных приспособлений, получа необходимую величину усили за счет нужного их количества.The proposed device also makes it possible to carry out the prestressing of large-span heavy structures directly during their installation with the help of conventional fastening devices, obtaining the necessary amount of force due to the required number of them.
