Устройство содержит опорную раму 1, выполненную сборной из телескопически сое диненных между собой Г-образных секций 2, снабженных упорными пластинами 3. Внутри рамы 1 установлен силовой цилиндр 4, который соединен тягами 5 с каждым углом рамы 1. На последней смонтированы привод 6, ведущие 7 и ведомые звездочки 8, на которых установлена замкнутая втулочно-роликовая цепь 9, на одном из звеньев которой закреплен укладчик 10 арматуры 11, сматываемой с бобины 12. Укладчик арматуры имеет натяжное приспособление в виде фильеры 13 с регулируемой калибрующей частью.The device comprises a support frame 1, made of a team of telescopically interconnected G-shaped sections 2, equipped with thrust plates 3. Inside the frame 1, a power cylinder 4 is installed, which is connected by rods 5 to each corner of the frame 1. The drive 6, leading 7 and driven sprockets 8, on which a closed sleeve-roller chain 9 is installed, on one of the links of which a stacker 10 of the reinforcement 11 is wound from the bobbin 12. The reinforcement stacker has a tension device in the form of a die 13 with an adjustable gauge th part.

Рама 1 смонтирована с возможностью подъема по высоте для подачи под нее поддона-тележки 14 с установленным на нем составным блоком 15, обжатым в нижней части упорами 16. Для намотки арматуры блок 15 имеет на боковой поверхности паз 17.The frame 1 is mounted with the possibility of lifting in height for feeding under it a pallet truck 14 with a composite block 15 mounted on it, crimped at the bottom of the stops 16. For winding the reinforcement, block 15 has a groove 17 on the side surface.

Устройство работает следующим образом.The device operates as follows.

Составной блок 15 на поддоне-тележке 14 подают под раму 1, после чего ее опускают и включают силовой цилиндр 4, который через тяги 5 воздействует на Г-образные секции 2, упорные пластины 3 которых в свою очередь обжимают блок 15 в верхней части и одновременно фиксируют раму 1 относительно блока.The composite block 15 on the pallet-carriage 14 is fed under the frame 1, after which it is lowered and the power cylinder 4 is turned on, which through the rods 5 acts on the L-shaped sections 2, the thrust plates 3 of which in turn compress the block 15 in the upper part and at the same time fix the frame 1 relative to the block.

Арматуру 11 с бобины 12 пропускают через фильеру 13 укладчика 10 и конец ее анкеруют в пазу 17 блока 15. После этого включают привод 6, который вращает звездочку 7, в результате чего цепь 9 перемещается по периметру блока 15, а укладчик осуществляет укладку арматуры 11 с натяжением в паз 17 блока 15. Необходимое усилие натяжения арматуры 11 обеспечивается за счет протягивания ее через калибрующую часть фильеры 13.The reinforcement 11 from the bobbin 12 is passed through the die 13 of the stacker 10 and its end is anchored in the groove 17 of the block 15. After that, the drive 6 is turned on, which rotates the sprocket 7, as a result of which the chain 9 moves along the perimeter of the block 15, and the stacker carries out the installation of the reinforcement 11 s tension in the groove 17 of the block 15. The necessary tension force of the reinforcement 11 is provided by pulling it through the calibrating part of the die 13.

После окончания намотки арматуры 11 выключают привод 6 перемещения цепи 9 с укладчиком 10, анкеруют конец намоточной арматуры в пазу 17 блока 15, затем снижают давление в силовом цилиндре 4, 10 в результате чего прекращается обжатие блока 15 упорными пластинами 3 секций 2 рамы 1. После этого последнюю поднимают, поддон-тележку 14 с напряженным блоком 15 перемещают к следующему технологическому посту, освобождая место для 15 очередного блока 15, после чего цикл намотки арматуры повторяют.After winding the reinforcement 11, turn off the drive 6 for moving the chain 9 with the stacker 10, anchor the end of the winding reinforcement in the groove 17 of the block 15, then reduce the pressure in the power cylinder 4, 10, as a result of which the crimping of the block 15 is stopped by the thrust plates 3 sections 2 of the frame 1. After this last lift, the pallet truck 14 with the strained block 15 is moved to the next process station, making room for 15 of the next block 15, after which the winding cycle of the reinforcement is repeated.

Изобретение позволяет повысить степень предварительного напряжения строительных элементов типа составных блоков за счет создания предварительного сило²⁰ вого обжатия блоков до и в процессе намотки на них арматуры, в результате чего намотанная с натяжением арматура не только сама по себе обжимает блок, но и сохраняет предварительное его обжатие. 25The invention allows to increase the degree of prestressing of building elements of the type of composite blocks by creating a preliminary force ²⁰ compression of the blocks before and during the winding of the reinforcement on them, as a result of which the reinforcement wound with tension not only compresses the block by itself, but also retains its preliminary compression . 25

Claims

The invention relates to devices for winding reinforcement on building products for the creation of their prestressing. The purpose of the invention is to increase the degree of prestressing of building elements such as composite blocks. FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. 2; in fig. 4 shows a section B-B in FIG. 3. The device contains a support frame 1, made by a team of telescopically connected to each other L-shaped sections 2, equipped with stop plates 3. Inside the frame 1 there is a power cylinder 4, which is connected by steps 5 with each of the main frame 1. On the latter are mounted drive 6, leading 7 and driven sprockets 8, on which a sleeve-roller chain 9 is installed, on one of the links of which is placed a stacker 10 of the armature 11, unwound from a reel 12. The stacker of the armature has a tensioning device in the form of a die 13 with adjustable gauge uyuschey part. The frame 1 is mounted with the possibility of lifting height for supplying the pallet truck 14 under it with the composite block 15 mounted on it, crimped in the lower part by the stops 16. The block 15 has a groove 17 on the side surface. The device works as follows. The composite unit 15 on the pallet-carriage 14 is fed under the frame 1, after which it is lowered and the power cylinder 4 is turned on, which through drafts 5 acts on the L-shaped sections 2, the stop plates 3 of which in turn compress the block 15 in the upper part and at the same time fix the frame 1 relative to the block. The armature 11 from the reel 12 is passed through the die plate 13 of the stacker 10 and its end is anchored in the slot 17 of block 15. After this, the actuator 6 is turned, which rotates the sprocket 7, as a result of which the chain 9 moves along the perimeter of the block 15, and the stacker 10 carries out the fitting 11 with tension into groove 17 of block 15. The required tension of the reinforcement 11 is provided by pulling it through the calibrating part of the nozzle 13. After winding the reinforcement 11, turn off the drive 6 of moving the chain 9 with the stacker 10, anchor the end of the winding reinforcement in the groove 17 block 15, then the pressure in the power cylinder 4 is reduced, as a result of which the compression of the block 15 is stopped by thrust plates 3 sections 2 of the frame 1. After the latter is lifted, the pallet-cart 14 with the tension block 15 is moved to the next technological post, freeing up space for the next block 15, after which the reinforcement winding cycle is repeated. The invention makes it possible to increase the degree of prestressing of building elements such as composite blocks by creating preliminary force reduction of the blocks before and during the winding of reinforcement on them, as a result of which the reinforcement wound with tension not only compresses the block itself, but also preserves the preliminary his compression. Claims The device for winding rebar, containing an armature stacker with tensioning device mounted on the base frame and a driving closed sleeve-roller chain, characterized in that, in order to increase the degree of prestressing of building elements of the type of composite blocks, the frame is made of telescopically connected telescopes between each L-shaped sections with thrust plates and is equipped with an internal cylinder installed inside it, which is connected to the corners of the frame with the help of t g, while closed The stub shaft is mounted around the perimeter of the frame, and the reinforcement stacker is attached to one of the links in the chain.
