Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement cages for inner leaf plates, specifically a steel reinforcement cage for inner leaf plates. Background Technology

[0002] Currently, in the domestic production of prestressed piles, the internal reinforcing cage typically consists of a number of reinforcing bars evenly distributed along a circular or square pattern. Using roll welding equipment, thinner diameter cold-drawn steel wires are welded to the reinforcing bars in a spiral manner to form ring reinforcement, thus assembling a complete reinforcing cage with a certain rigidity. During production, the internal reinforcing bars are used for tensioning, creating prestress in the longitudinal direction of the reinforcing cage.

[0003] A search revealed an existing patent (publication number: 202021247583.5) that discloses a reinforcing cage, including a reinforcing cage, main bars, and end pile sleeves. The main bars are arranged inside the reinforcing cage, with both ends connected to the end pile sleeves. The reinforcing cage includes longitudinal bars and ring bars. A connector for fixing the end pile sleeves is provided between the end pile sleeves and the reinforcing cage. While this patented technology eliminates the need for welding to the ring bars, reducing mechanical losses to the main bars during the reinforcing cage forming process and lowering the difficulty and labor intensity for workers, and because the end plate used in this invention has no waist-shaped holes, eliminating the need to transfer the main bars behind the pier head through the waist-shaped holes to the small holes, allowing them to be directly inserted into the countersunk holes in the end plate, simplifying the operation, it presents challenges in assembling the reinforcing bars into a reinforcing cage. Furthermore, the assembly process requires multiple workers to support the reinforcing bars to prevent them from tilting, resulting in significant physical exertion for the workers.

[0004] Therefore, those skilled in the art have provided a steel reinforcement cage for inner leaf plates to solve the problems mentioned in the background art. Utility Model Content

[0021] The above technical solution involves moving the extension handle to rotate the central disc, which causes the connecting piece to change direction and angle during the rotation of the central disc. This causes the expansion head to extend and expand outward, supporting multiple steel bars.

[0022] Furthermore, a tension spring is fixedly connected to one side of each of the multiple extension handles, and the other end of the tension spring is fixedly connected to one side of the inner wall of the bottom groove of the outer ring cylinder block.

[0039] In this embodiment, a steel reinforcement cage for an inner leaf plate is described. It should be noted that the positioning cylinders 3 and cone blocks 6 allow for the relocation of multiple positioning cylinders 3 during use, enabling them to accommodate various sizes of steel bars. This achieves easy positioning and limiting of steel bars at different locations, broadening the device's applicability, simplifying operation, and providing a highly effective and rapid positioning effect. Furthermore, the expansion head 14 and extension handle 17 allow the central disc 12 to rotate when the extension handle 17 is moved. This causes the connecting piece 15 to change direction and angle during the rotation of the central disc 12, leading to the expansion head 14 extending and expanding outwards. The expansion head 14 supports multiple steel bars, facilitating the weaving and assembly of the cylindrical steel reinforcement cage for the inner leaf plate, reducing labor, and making binding and welding easier and more convenient.

[0040] The working principle of the above embodiment is as follows: When assembling multiple steel bars to form a cylindrical steel cage for the inner leaf plate, the multiple steel bars are placed into the positioning cylinder 3 respectively. Then, the rectangular slider 2 at the top of the main body 1 is slid to bring the multiple steel bars to the designated position. Then, the cone block 6 is pressed to insert the cone block 6 at the top of the spring column 5 into the groove of the horizontal plate 4, thereby locking the position of the steel bars. Then, the hand disc 9 in the middle of the device is rotated to make the threaded rod 8 engage with the threaded part of the nut cylinder 7. Then, the threaded rod 8 moves the mounting plate 10 to the middle of the steel bars. Then, the worker moves the extension handle 17 from the gap between the steel bars, so that the central disc 12 also rotates when the extension handle 17 is moved. At this time, the tension spring... 19 stores power, and then the support rod 13 twists as the central disc 12 rotates. The connecting piece 15 also rotates during the rotation of the support rod 13, and the bottom sliding rod 16 of the support rod 13 rotates and slides on the top of the outer ring cylinder block 11, so that the expansion head 14 can expand outward. Then, as the expansion head 14 supports the middle of the steel bar, the insert 18 at one end of the extension handle 17 is pulled out and inserted into the groove on the outer wall of the mounting plate 10, so that the position of the expansion head 14 is fixed, thereby completing the shaping of the cylindrical steel cage for the inner leaf plate, which facilitates the binding and welding. After the insert 18 is pulled out, the extension handle 17 will be restored by the rebound force of the tension spring 19, so that the expansion head 14 is retracted.
