Description

Technical Field

[0001] This utility model relates to the field of steel bar frame assembly technology, and in particular to a steel bar formwork frame for precast beam yards. Background Technology

[0002] A reinforced concrete film frame typically refers to a structure used for covering agricultural greenhouses. This structure comprises reinforcing steel bars and a polyethylene film, used to support and cover the entire greenhouse. The steel bars provide structural support, while the polyethylene film covers and protects crops from harsh weather. This structure is widely used in agricultural production, helping to provide ideal temperature and humidity conditions to promote crop growth. Current reinforced concrete film frames often employ fixed molds or simple positioning supports.

[0003] An existing authorized publication number (CN222406410U) describes a precast beam yard rebar formwork frame, comprising a base plate, a mounting frame, a mounting frame, and a movable plate. A hydraulic cylinder is mounted on the upper end of the base plate, and a base plate arranged in a linear array is mounted on the lower end of the base plate. The mounting frame is mounted on the upper end of one side of the base plate, and the surface of the mounting frame has positioning holes arranged in a linear array. The mounting frame is mounted to the positioning holes using screws, and a movable plate is mounted on one side of the mounting frame. This device facilitates the adjustment of the spacing between rebars and adapts to rebars of various diameters for auxiliary formwork installation. It solves the problem of existing rebar formwork frames that cannot easily assist in the positioning and processing of various types of rebars, and can use screws to adjust the spacing of the rebars, achieving convenient and rapid auxiliary rebar support and assembly.

[0004] Regarding the aforementioned technologies, the existing steel reinforcement formwork has the following drawbacks: the fixed mold cannot adapt to the production needs of precast beams of different specifications, and changing the mold is time-consuming, labor-intensive, and costly; the simple positioning bracket relies on manual operation, which is not only inefficient, but also prone to uneven spacing and positional deviation of steel bars due to human measurement errors, affecting the mechanical properties of the precast beams. Therefore, this utility model provides a steel reinforcement formwork for precast beam yards. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1: Reference Figure 1-5The diagram illustrates a precast beam yard rebar formwork frame, comprising a placement platform 1. The placement platform 1 serves as the foundational load-bearing component of the entire device, providing a stable installation plane and working platform for subsequent components, ensuring the entire formwork frame remains stable during rebar processing. A placement frame 3 is mounted on top of the placement platform 1. The placement frame 3 supports single transverse rebars and serves as the initial carrier for rebar positioning. Its regular structural design provides a stable placement space for the rebars, facilitating subsequent precise adjustment and fixing. Detection components are installed at both ends of the placement frame 3. These detection components determine the accuracy of the rebar's transverse position within the placement frame 3, forming the core of automatic rebar alignment. Their precise detection capability directly affects the accuracy of rebar positioning. The detection components include components integrated with the placement frame 3... The connecting frame 8, which is fixedly connected to the side wall, supports and fixes the laser emitter 11 and the laser signal receiving plate 10, ensuring that their relative positions remain constant. This provides structural support for accurately detecting the position of the rebar. One end of the connecting frame 8 is equipped with the laser emitter 11, which emits a straight laser beam. The lateral position of the rebar is determined by illuminating its edge, providing a detection signal for rebar centering. The other end of the connecting frame 8 is equipped with the laser signal receiving plate 10, which receives the laser beam emitted by the laser emitter 11 and uses the presence of a red laser dot on the plate to provide feedback on the rebar's position. This is a crucial basis for determining whether the rebar is centered. A pressure sensor 12 is installed inside the placement frame 3. The pressure sensor 12 can sense whether the rebar is placed in the placement frame 3. Only after the rebar is detected will the subsequent detection and adjustment process be triggered, avoiding unnecessary work and improving equipment operating efficiency. The placement frame 3 has a sliding groove inside, and a guide rail 23 is provided inside the sliding groove. The sliding groove and guide rail 23 provide a moving track for the fine-tuning component, allowing the fine-tuning component to slide smoothly in a preset direction, providing movement space for precise adjustment of the rebar position. The placement frame 3 is equipped with a fine-tuning component, which is used to adjust the lateral position of the rebar placed in the placement frame 3 to ensure that the rebar position meets the design requirements. It is a key execution component for achieving precise rebar positioning. The fine-tuning component includes a slider 15 that is slidably connected to the inside of the guide rail 23. The slider 15 slides on the track 23, causing the moving block 13 to move, thereby adjusting the position of the rebar. Its excellent sliding performance ensures the smoothness and accuracy of the position adjustment. The moving block 13 is fixedly connected to the side wall of the slider 15. The moving block 13 directly contacts the rebar and drives the rebar to move. Its structural strength and stability determine the reliability of the rebar position adjustment. Multiple toothed blocks 22 are fixedly connected to the bottom of the moving block 13. The toothed blocks 22 mesh with the gear 17, converting the rotational motion of the gear 17 into the linear motion of the moving block 13, providing power transmission for the rebar position adjustment. The side wall of the placement frame 3 is fixedly connected to the motor 16. The motor 16 serves as a power source, driving the gear 17 to rotate by outputting stable rotational power, providing power for the automatic adjustment of the rebar position.A gear 17 is fixedly connected to the output end of the motor 16. The gear 17 meshes with multiple toothed blocks 22, transmitting power from the motor 16 to the moving block 13 via the gear 17. This enables precise fine-tuning of the rebar position, and the accurate transmission ratio ensures the accuracy and controllability of the rebar position adjustment.

[0026] Example 2: Reference Figure 1-5Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a hydraulic push rod 4 is fixedly connected to the top of the placement platform 1. The hydraulic push rod 4 serves as the core power component for adjusting the height of the placement frame 3. Through hydraulic transmission, it can precisely control the vertical movement of the placement frame 3, flexibly adapting to the height positioning requirements of different specifications of reinforcing bars, ensuring that the reinforcing bars are at the designed elevation. The output end of the hydraulic push rod 4 is fixedly connected to the placement frame 3, transmitting the power generated by the hydraulic push rod 4 to the placement frame 3, enabling the placement frame 3 to adjust its height as needed, achieving precise vertical positioning of the reinforcing bars. A guide rod 2 is slidably connected to the top of the placement platform 1, providing guidance for the placement frame 3 during lifting and lowering, ensuring that the placement frame 3 moves vertically. Smooth movement prevents deviation or swaying, enhancing the stability and positioning accuracy of the entire device. One end of the guide rod 2 is fixedly connected to the bottom of the placement frame 3, ensuring synchronous movement between the guide rod 2 and the placement frame 3. This allows the placement frame 3 to rise and fall along the direction of the guide rod 2 under the drive of the hydraulic push rod 4, maintaining accurate positioning. Support legs 9 are fixedly connected to the bottom of the placement platform 1, supporting the entire platform 1 and its upper structure. These legs transfer the weight of the device and the load generated during operation to the foundation, ensuring the stability of the entire membrane frame during operation and preventing tilting or settlement. Multiple vertical rods 6 are fixedly connected to the top of the placement platform 1. These vertical rods 6 serve as vertical support structures for positioning multiple reinforcing bars, providing a vertical positioning reference for the bars and facilitating positioning of multiple reinforcing bars. For the parallel installation and fixing of the reinforcing bars, multiple limiting grooves 18 are provided on the side walls of the vertical rods 6. The limiting grooves 18 provide a lateral limiting channel for the reinforcing bars, allowing multiple reinforcing bars to pass through the limiting grooves 18 and be arranged in an orderly manner, thereby achieving the initial positioning of the reinforcing bars in the lateral position. Multiple limiting frames 19 are fixedly connected to the side walls of the vertical rods 6. The limiting frames 19 are used in conjunction with the limiting grooves 18 to provide an installation base for the screw rods 21 and the limiting discs 20, assisting in the final fixing of the reinforcing bars. The top and bottom of the limiting frames 19 are threaded with screw rods 21. The screw rods 21 can drive the limiting discs 20 to move vertically by rotating. By adjusting the screw rods 21, the reinforcing bars passing through the limiting grooves 18 can be clamped and fixed to ensure that the reinforcing bars will not shift during the binding process. One end of the screw rod 21 is... A fixed connection limit plate 20 is provided, which is in direct contact with the reinforcing bar. The reinforcing bar is pressed into the limit groove 18 by the tightening action of the screw 21, achieving reliable fixing of the reinforcing bar and ensuring the overall stability of the reinforcing bar skeleton. A fixing frame 14 is fixedly connected to the side wall of the placement frame 3, providing an installation platform for the electric push rod 5. This ensures that the electric push rod 5 can be stably installed on the placement frame 3, providing support for subsequent lateral fixing of the reinforcing bar. The electric push rod 5 is fixedly connected to the top of the fixing frame 14. As the power component for lateral fixing of the reinforcing bar, the electric push rod 5 can quickly push the limit plate 7 towards the reinforcing bar via electric drive, achieving initial lateral fixing of the reinforcing bar and improving the positioning efficiency. The output end of the electric push rod 5 is fixedly connected to the limit plate 7.Driven by the electric push rod 5, the limiting plate 7 contacts the reinforcing bar and applies pressure, fixing the reinforcing bar laterally in a predetermined position to prevent lateral displacement during subsequent processing and ensure accurate positioning.

[0027] The working principle of this device is as follows: When using this device, first place a single horizontal steel bar on the placement frame 3. When the pressure sensor 12 detects the presence of the steel bar, it will automatically activate the laser emitters 11 at both ends of the placement frame 3. When the infrared light just passes through the edge of the steel bar and a red dot is left on both sides of the laser signal receiving plate 10, if there is no red dot on the laser signal receiving plate 10 at one end, the motor 16 is started. The motor 16 rotates the gear 17, and the gear 17 meshes with multiple tooth blocks 15, causing the moving block 13 to move the steel bar until the position is correct. Then, the hydraulic push rod 4 is activated to adjust the height of the placement frame 3. The electric push rod 5 is activated to use the limiting plate 7 to complete the positioning and fixing of the steel bar. Then, multiple steel bars are passed through different limiting grooves 18. The screw 21 is turned to use the limiting plate 20 to complete the positioning of the steel bar and complete the splicing.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
