Description
Известны устройства дл воспри ти усилий от арматуры, наматываемой на штыри при изготовлении железобетонных предварительно напр женных железобетонных изделий.Devices are known for sensing forces from reinforcement wound on pins in the manufacture of reinforced concrete prestressed reinforced concrete products.
Недостатком известных ycTpoiiCTB вл етс неиланныГ поворот или смещени штырей при расналубке.A disadvantage of the known ycTpoiiCTB is the non-hinge pivoting or shifting of the pins during the breakup.
Устройство, выполненное согласно изобретению, лн1пено этого недостатка . Сушность изобретени заключаетс в том, что штыри шарпирно укреплены на ноддоне или другом элементе устройства и св заны изо.тированными фиксированно длины стержн миЭти стержни при распалубке удлин ютс за счет нагрева электрическим током.The device made according to the invention, ln1peno of this disadvantage. Dryness of the invention lies in the fact that the pins are sharply fastened to the noddon or other element of the device and are connected by fixed lengths of fixed rods. These rods are elongated during the dismantling process by heating with an electric current.
На фиг. 1 изображена примерна схема расположени предложенных устройств на поддоне; на фиг. 2 -- разрез предложенного устройства по А-А на фиг, 1.FIG. 1 shows an exemplary arrangement of the proposed devices on a pallet; in fig. 2 is a section of the proposed device according to A-A in FIG. 1.
Устройство монтируетс на ноддоне / с железобетонным изделием 2, имеюш,им напр женную арматуру 3, и состоит из поворотного штыр 4 на оси 5, изолирующих втулок 6, крепежной гайки 7, электроконтактов 8, изолированного фиксированной длины стержн 9, вилки 10 и опоры 11.The device is mounted on a nodd / with a reinforced concrete product 2, having tensioned reinforcement 3, and consists of a rotary pin 4 on the axis 5, insulating sleeves 6, a fastening nut 7, electrical contacts 8, an insulated fixed length rod 9, forks 10 and a support 11 .
Все стержни 9 соединены носледовательно дл питани током.All rods 9 are connected in succession for current supply.
Работа по ослаблению напр женной арматуры производитс следующим образом.The work on weakening the reinforcement is performed as follows.
На вертикально выставленные штыри 4 наматываетс преднапр женна арматура (или укладываютс в зажимы штырей стержни), после чего изделие формуетс и проходит цикл термообработки. Перед обрезкой к контактам двух стержней 9 подключаетс сварочный трансформатор , и ток, проход через стержни 9, нагревает их.The pre-stressed reinforcement is wound on the vertically exposed pins 4 (or the rods are put into the clamps of the pins), after which the product is molded and undergoes a heat treatment cycle. Before cutting, a welding transformer is connected to the contacts of the two rods 9, and the current passing through the rods 9 heats them.
При нагреве стерлсень удлин етс , а нат нута арматура, поворачива штырь, сбрасывает свое нат жение на участке выхода из железобетонного издели до штыр .When heated, the sterren lengthens and the reinforcement tightens, turning the pin, to relieve its tension at the exit from the concrete product to the pin.
Таким образом, не опаса сь последствий проскальзывани арматуры и по влени трещин или скалывани слоев бетона, возможна люба последовательна обрезка арматуры.Thus, without fear of the consequences of reinforcement slipping and the appearance of cracks or shearing concrete layers, any consistent trimming of reinforcement is possible.
