Изобретение относитс к устройствам дл нат жени арматуры при изготовлении предварительно напр женных железобетонных изделий.The invention relates to devices for tensioning reinforcement in the manufacture of prestressed concrete products.
По основному авт. св. № 571565 известио устройство дл предварительного ат жеии арматурных стержней, включающее 5 механизм образовани анкеров на концах стержней н нагрева последних, привод дл изменени рассто ни между анкерами и механизм дл укладки стержней в упоры формы, при этом устройство снабжено при- j. способлением дл измерени размера между упорами и блоком сравнени и корректировани рассто ни между анкерами соот- . ветственно рассто нию между упорами, вы .полненными в виде электрически св занных между собой командного блока управлени , is усилител и датчика сигналов (1.According to the main author. St. No 571565 is a device for pre-reinforcement of reinforcing rods, including 5 mechanisms for forming anchors at the ends of rods and heating them, a drive for changing the distance between the anchors and a mechanism for placing rods into the shape stops, while the device is equipped with j. a method for measuring the size between the lugs and the comparison unit and adjusting the distance between the anchors, respectively. Corresponding to the distance between the stops, you are filled in the form of an electrically connected control unit, is the amplifier and the sensor signals (1.

Недостатком известного устройства вл етс возможность выброса стержней из упоров при ударе стержней о поддон формы при их укладке или не точна фиксаци стержней в цапфах при нат жении, что приводит к браку изготовлени железобетонных изделий.A disadvantage of the known device is the possibility of ejecting the rods from the stops when the rods hit the shape pallet when they are laid or if the rods are not accurately fixed in the trunnion during tension, which leads to rejects in the manufacture of reinforced concrete products.
Цель изобретени - повышение точности фиксации арматурных стержней при нат жении .The purpose of the invention is to improve the accuracy of fixation of reinforcing bars under tension.
Цель достигаетс тем, что в устройстве дл предварительного нат жени арматурных стержней механизм укладки стержней в упоры формы снабжен приспособлением дл досылки стержней в упоры, выполненным в виде поршневого привода, на штоке которого закреплен фиксатор.The goal is achieved by the fact that in the device for pre-tensioning rebar, the mechanism for placing the rods in the shape stops is equipped with a device for filing rods in the stops, made in the form of a piston drive, with a retainer fixed to the stem.
На фиг. I изображен механизм укладки стержней в упоры формы с приспособлением дл досылки стержней; на фиг. 2-приспособление дл досылки стержней в плоскости продольного разреза формы.FIG. I shows the mechanism for stacking rods in shape stops with a device for ramming rods; in fig. 2-device for filing rods in the plane of the longitudinal section of the form.
Механизм укладки арматурных стержней в упоры формы устройства дл их предварительного нат жени состоит из соединенного с прибором I поворотного рычага 2, направл ющих 3 н приспособлени дл дОсылкн арматурных стержней 4 в упоры 5 формы 6, выполненного в виде поршневого привода 7, на штоке которого закреплен фиксатор 8.The mechanism for placing the reinforcing rods into the shape stops of the pre-tensioning device consists of a rotating arm 2 connected to the device I, guiding 3 n devices for connecting reinforcing rods 4 to the stops 5 of the shape 6, made in the form of a piston drive 7, on the rod of which is fixed lock 8.
Устройство работает следующим образом.The device works as follows.
После образовани на концах арматурных стержней 4 анкеров и нагрева стержнейAfter 4 anchors are formed at the ends of the reinforcing bars and the rods are heated
