Description

Изобретение относитс к устройствам дл навивки предварительно напр женной арматуры на поверхности и цилиндрических железобетонных соору;жений .The invention relates to devices for winding pre-stressed reinforcement on the surface and cylindrical reinforced concrete structures.

Известно устройство дл навивки арматуры на поверхность цилиндрического элемента, содержащее подвижную платформу с вертикальной направл ющей , на которой закреплен разъемный поворотный стол с приводом.и приспособлением дл навивки арматуJM 1.A device for winding reinforcement onto the surface of a cylindrical element, comprising a movable platform with a vertical guide, on which a detachable rotary table with a drive is mounted, and a device for winding reinforcement JM 1 is known.

Это устройство может быть использовано дл навивки арматуры только на цилиндрические строительные элементы ограниченной высоты и небольшого диаметра.This device can be used to wind reinforcement only onto cylindrical building elements of limited height and small diameter.

Известно также устройство дл навивки арматуры на поверхность цилиндрического сооружени , содержащее кольцевую платформу с механизмом подъема и установленные на ней механизмы нат жени и укладка арматура, при этом под платформой установлена кольцева опорна ферма, на ферме и платформе смонтированы Jiадиaльнo ориентированные домкраты, а механизм подъема платформы выполн.ен в виде вертикально установленных домкратов.It is also known a device for winding reinforcement onto the surface of a cylindrical structure containing an annular platform with a lifting mechanism and tensioning mechanisms installed on it and laying the armature. performed in the form of vertically installed jacks.

Claims

For this, in the coiling device EI, containing a frame with supporting wheels for rollers mounted on annular guides, a carriage movable in height of the frame with a device for placing the reinforcement and driving mechanisms, the end of which is installed roller, move along the reinforcement previously laid on the structure, with the upper section and the middle part connected to the carriage by means of a hydraulic cylinder, and in the piston cavity of which a spring is installed. FIG. 1 shows a general view. devices plan; in fig. 2 - the node in FIG. one; in fig. 3 shows section A-A in FIG. 1. The device consists of paivBj 1 moving along annular guides 2 on support rollers 3 by means of a mechanism consisting of sprockets 4 which engage with gear rack 5 and drive 6. On: frame 1 there are vertical guides 7, the carriage 8 moves along the mountain; its drum 9 has a lever 15 pivotally fixed, the roller 16 is attached to the free end. coil 19. The device works as follows. The device is mounted on the annular guides 2, while 15 are retracted from the surface of the concrete structure 14 by applying pressure to the piston cavity of the hydraulic cylinder 17. The spring 18 is compressed. After the device is mounted on the ring guides 2, the armature 13 passes through the gripping drum 9 and is fixed to the reinforced concrete structure 14. After performing these operations, the device using the drives b, connected to the sprockets 4, begins to move along. annular guides 2, while reinforcement 13 is wound onto the surface of structure 14. The winding pitch is determined by moving carriage 8 along verteral guides 7. The tension of reinforcement 13 is provided by the resistance of the braking device 12. Before the frame 1 moves, pressure in the hydraulic cylinder 17 is relieved and the spring 18 presses the roller 16 to the surface of the structure 14 .. As the roller 16 is in the plane of the holding drum 9, it always moves along the previously laid turn of the reinforcement 13. Thus, when the The armature 13 directly behind the gripping reel 9 unwinds no more than one coil of the laid armature 13. Claims Armature for winding armature onto the surface of a cylindrical structure containing a frame with rollers mounted on the ring guides, height-adjustable carriage frame with fittings and actuators, in that, in order to prevent the reinforcement laid on the construction from unwinding when the winding of its coil is broken, the carriage is equipped with a hinge fixed thereto one end of a lever on the free end of which a roller which is moved along the previously laid on the reinforcement structure, wherein the lever in the middle part connected with the carriage by means of a hydraulic cylinder, a piston chamber which is installed the spring.
