Description

Известны устройства дл  нат жени  пучка проволок арматуры с использованием р да гидравлических домкратов, нолости которых дл  обеспечени  равномерности нат жени  стержней св заны между собой каналами.Devices for tensioning a bundle of reinforcement wires are known using a series of hydraulic jacks, the legs of which, to ensure uniform tension of the rods, are interconnected by channels.

Описываемое устройство отличаетс  от известных тем, что, с целью создани  одинаковых усилий в нат гиваемых проволоках, в нем применены амортизаторы, выполненные в виде сообщающихс  цилиндров с поршн ми, имеющими элементы креплени  дл  нат гивани  проволок.The described device differs from the known ones in that, in order to create equal forces in the tensioned wires, it uses shock absorbers made in the form of communicating cylinders with pistons having fastening elements for tensioning the wires.

На чертеже схематически изображено описываемое устройство, состо щее из двухходового одноцилиндрового домкрата 1, на который надеваетс  обойма 2. По периферии обоймы 2 расположены цилиндрыамортизаторы 3. Цилиндры имеют поршни 4 и соединены между собой каналами. На щток 5 поршн  надеваетс  насадка 6, в которой крепитс  нат гиваема  проволока 7. В цилиндры наливаетс  масло на 1/3 их объема, и усили  нат гиваемых проволок через порщни 4 передаютс  на жидкость, котора , перераспредел  сь через каналы, соедин ющие цилиндры, нагружает каждую проволоку равномерно. Общее нат жение осуществл етс  домкратом /.The drawing shows schematically the described device consisting of a two-way single-cylinder jack 1 on which the sleeve 2 is fitted. Around the periphery of the holder 2 are located the cylinders of the shock absorbers 3. The cylinders have pistons 4 and are interconnected by channels. A nozzle 6 is put on the piston pin 5, in which the tensioning wire 7 is attached. Oil is poured into the cylinders by 1/3 of their volume, and the forces of the tensioning wires are transferred through the media 4 to the liquid, which is redistributed through the channels connecting the cylinders, loads each wire evenly. The total tension is carried out by a jack.

Предмет изобретени Subject invention

Устройство дл  нат жени  пучка проволок арматуры железобетона с рабочим органом в виде гидродомкрата, отличающеес  тем, что, с целью создани  одинаковых усилий в нат гиваемых проволоках, на цилиндр домкрата насажена обойма, по периферии которой расположены амортизаторы в виде сообщающихс  цилиндров с поршн ми, имеющими элементы креплени  дл  нат гиваемых проволок, при возникновении неодинаковых усилий, в которых происходит перераспределение жидкости между цилиндрами амортизаторов.A device for tensioning a bundle of reinforcement concrete wires with a working body in the form of a hydraulic jack, characterized in that, in order to create equal efforts in the tensioned wires, a sleeve is mounted on the jack cylinder, on the periphery of which there are shock absorbers in the form of communicating cylinders with pistons fasteners for tensioned wires, in the event of unequal forces in which there is a redistribution of fluid between the cylinders of the shock absorbers.
