Technical Field

[0001] This utility model relates to the technical field of rebar cage processing and positioning devices, specifically a rebar cage mold frame. Background Technology

[0002] In engineering projects such as bridge pile foundations and building foundations, steel reinforcement cages serve as the core load-bearing components of concrete structures. Reinforcement cages are typically made up of horizontal ring reinforcement bars and longitudinal reinforcement bars, and it is necessary to ensure that the spacing and diameter of the reinforcement bars meet the design requirements.

[0003] Currently, the commonly used rebar cage formwork in engineering is mainly the fixed formwork, which limits the size of the rebar cage by welding a fixed support structure. The fixed formwork can only be used for a single specification of rebar cage. In engineering, multiple sets of formwork need to be made for rebar cages of different diameters, resulting in high equipment investment costs and the formwork occupying a lot of storage space.

[0004] Therefore, it is necessary to design an adjustable rebar cage formwork frame that can produce rebar cages of different diameters. Utility Model Content

[0010] Furthermore, the limiting chassis is provided with angle limiting posts; the angle limiting posts are vertically arranged on the limiting chassis, and multiple angle limiting posts are distributed circumferentially on the limiting chassis.

[0011] Beneficial effects This utility model uses an adjustable connector to drive the movable bracket to move along the fixed arm, which can adjust the position of the movable bracket, so that the mold frame can be adapted to the processing of steel cages of different diameters.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] To achieve the above objectives, this utility model provides the following technical solution, such as... Figure 1-5 As shown, a steel cage formwork frame includes a central fixed support 1, a movable support 2, and an adjustable connector 3. The intermediate fixed support 1 is set on the ground and consists of a central column 11 and eight fixed arms 12. The eight fixed arms 12 are evenly distributed around the central column 11 in a circular array, forming a symmetrical star-shaped radial structure, which provides basic support for the entire mold frame.

[0018] Each fixed arm 12 has a corresponding movable support 2 on its outer side, with a total of 8 movable supports 2. The movable supports 2 are movably mounted on the fixed arm 12 and can move along the extension direction of the fixed arm 12. The movable supports 2 are frame structures used to cooperate with the fixed supports as positioning references for the rebar cage. The position of the movable supports 2 can be adjusted according to the specifications of the rebar cage.

[0019] Height limiting posts 21 are welded at intervals on the outer side of the movable support 2. The height limiting posts 21 are perpendicular to the outer side of the movable support 2 and extend outward. The spacing between them is determined by the design spacing of the annular steel bars 6 of the steel cage. An adjustable connector 3 is provided between the fixed arm 12 and the movable support 2. The distance between the fixed arm 12 and the movable support 2 is controlled by the adjustable connector 3, so as to adapt to the manufacturing requirements of steel cages with different diameter specifications.

[0020] Furthermore, the adjustable connector 3 includes a threaded sleeve 31 and a double-ended bolt structure 32; Two threaded sleeves 31 are respectively fixed on two adjacent sides of the fixed arm 12 and the movable bracket 2; the two threaded sleeves are set at the same height, and the two ends of the double-headed bolt structure 32 extend into the two threaded sleeves and are threadedly connected to the two threaded sleeves. The double-headed bolt structure 32 includes a central ring 33 and threads at both ends; by using a pry bar to pass through the ring 33 and then turning the pry bar, the adjustable connector 3 is rotated, causing the movable bracket 2 to move closer to or away from the central fixed bracket 1.

[0021] Furthermore, there are two adjustable connectors 3, which are arranged in parallel and adjusted synchronously to ensure that the movable support 2 moves in parallel.

[0022] Furthermore, it also includes a limiting chassis 4; the limiting chassis 4 is a ring structure cut from a steel plate, which is fixed to the fixed arm 12 by bolts and is coaxially set with the central column 11. The inner diameter of the limiting chassis 4 is adapted to the design diameter of the steel cage to be processed, and the inner circle of the limiting chassis 4 is in contact with the inner side of the movable support 2, which can limit the radial position of the movable support 2; the position of the movable support 2 is limited by the inner circle of the limiting chassis 4.

[0023] Furthermore, the limiting base 4 is provided with angle limiting posts 41; the angle limiting posts 41 are vertically arranged on the limiting base 4, and multiple angle limiting posts 41 are distributed circumferentially on the limiting base 4; in this embodiment, the interval angle between two adjacent angle limiting posts 41 on the limiting base 4 is 15 degrees, which is used to limit the circumferential installation position of the longitudinal reinforcing bars 7.

[0024] Working principle: The steel cage formwork serves as the foundation for positioning and shaping the steel bars, which are then tied together to form the steel cage. In this embodiment, the steel cage includes horizontal ring steel bars 6 and vertical longitudinal steel bars 7. Based on the diameter of the steel cage to be processed, select a suitable limiting base 4. The inner diameter of the limiting base 4 is the same as the design diameter of the steel cage to be processed. By passing a pry bar through the ring 33 in the middle of the double-headed bolt structure 32, the double-headed bolt structure 32 is turned, which drives the movable bracket 2 to move along the fixed arm 12; so that the inner side of the movable bracket 2 contacts the inner ring of the limiting base 4; and adjust the 8 movable brackets 2 to the same target position.

[0025] First, the ring-shaped reinforcing bars 6 are tied by bending the reinforcing bars into a ring shape that matches the diameter of the reinforcing cage. Then, the ring-shaped reinforcing bars 6 are clamped onto the height limiting posts 21 at the same height. The placement and tying of the ring-shaped reinforcing bars 6 in each layer are completed according to the preset spacing.

[0026] Then, the longitudinal reinforcement 7 is tied. The longitudinal reinforcement 7 is placed vertically so that its lower part is attached to the side wall of the angle limiting column 41 to ensure the circumferential position of the longitudinal reinforcement 7. Then, the longitudinal reinforcement 7 is tied and fixed to the ring reinforcement 6 of each layer one by one to form a complete reinforcement cage.

[0027] After processing, reverse the double-headed bolt structure 32 to retract the movable bracket 2 inward, separating the height limiting column 21 from the ring steel bar 6; start the hoisting equipment to lift the steel cage upward away from the formwork frame, completing the processing.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
