Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a steel cage frame. Background Technology

[0002] A rebar cage jig is a tooling device used to assist in the fabrication of rebar cages. It is used to fix, support, and position the rebars, ensuring the dimensional accuracy, shape stability, and binding efficiency of the rebar cage. Currently, rebar factories often use a single adjustable movable plate jig to process rebar cages. After the lower half of the rebar cage is processed, it is continuously rotated to create holes for placing the next rebar, until the entire rebar cage is completed. Because the upper half of the rebar cage is suspended during processing without the positioning and support of the jig holes, the rebar cage deflects due to its own weight. During the continuous rotation, the rebar cage deforms due to excessive deflection, resulting in substandard quality.

[0003] A related technology proposes a positioning device for bridge reinforcement cage fabrication, comprising a positioning jig base and a positioning jig body movably mounted on the positioning jig base. The positioning jig body is an integral, detachable ring-shaped or circular structure formed by connecting at least three arc-shaped steel plates with connectors and bolts. Several main reinforcement slots are provided on the ring-shaped or circular positioning jig body. This positioning device can improve the processing quality of the reinforcement cage, enabling rapid and accurate positioning of the main reinforcement bars, stiffening stirrups, and spiral stirrups, thereby effectively improving the binding accuracy and speed of the reinforcement cage.

[0004] However, the main bar slots of the aforementioned bridge steel cage fabrication positioning device are U-shaped or semi-circular grooves, and some of the main bar slots are located on the outer edge of the upper part of the positioning frame body. When the main bar is placed in the main bar slot at a near-horizontal position, the main bar slot cannot limit the main bar, which can easily cause the main bar to slip out of the main bar slot and thus make it impossible to successfully complete the binding of the steel cage. Utility Model Content

[0005] The purpose of this utility model is to provide a steel cage frame to solve the technical problem in the prior art where some main bar slots in the positioning device for bridge steel cage fabrication cannot effectively limit the main bars, causing the main bars to slip out of the main bar slots and thus making it impossible to successfully complete the binding of the steel cage.

[0028] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-4 As shown, this utility model provides a steel cage frame, including a support assembly 1 and a frame assembly 2. The frame assembly 2 includes a first positioning member 21 and a second positioning member 22. The first positioning member 21 is semi-circular and is connected to the support assembly 1 with its opening facing upward. The second positioning member 22 is semi-circular and is detachably connected to the first positioning member 21 with its opening facing downward. The first positioning member 21 and the second positioning member 22 together form a circular frame assembly 2. The inner wall of the first positioning member 21 has a plurality of first mounting grooves 211, and each of the plurality of first mounting grooves 211 has at least one side of its groove wall with an upward slope. The outer wall of the second positioning member 22 has a plurality of second mounting grooves 221, and each of the plurality of second mounting grooves 221 has at least one side of its groove wall with an upward slope.

[0033] During the fabrication of the reinforcing cage, reinforcing bars 100 are sequentially placed into the first mounting groove 211 and the second mounting groove 221, and then tied together to form the reinforcing cage. The first positioning member 21 and the second positioning member 22 form a circular frame assembly 2, which effectively supports the upper half of the reinforcing cage, preventing deflection due to its own weight during tying and improving the tying quality. Each of the multiple first mounting grooves 211 and multiple second mounting grooves 221 has at least one side of its groove wall with an upward slope. This allows the upward-sloping groove wall to effectively limit the reinforcing bars 100 when they are placed in the first mounting groove 211 or the second mounting groove 221, preventing them from slipping out and further ensuring the smooth completion of the reinforcing cage tying. The second positioning component 22 is detachably connected to the first positioning component 21. After the steel cage is tied, the second positioning component 22 can be removed from the first positioning component 21 to facilitate the removal of the steel cage from the steel cage frame.

[0034] For example, such as Figure 2 As shown, the first positioning element 21 and the second positioning element 22 are detachably connected by bolts 23, facilitating the disassembly of the second positioning element 22 by personnel. In other embodiments, the first positioning element 21 and the second positioning element 22 can also be connected by a pin, which is not specifically limited here.

[0035] Furthermore, such as Figure 2 As shown, multiple first mounting slots 211 are evenly distributed in a semi-circular array on the first positioning member 21, and multiple second mounting slots 221 are evenly distributed in a semi-circular array on the second positioning member 22. When the second positioning member 22 is connected to the first positioning member 21, the multiple first mounting slots 211 and the multiple second mounting slots 221 are evenly distributed in a circular array. After the reinforcing bars 100 are sequentially placed into the first mounting slots 211 and the second mounting slots 221, the reinforcing bars 100 are evenly distributed in a circular array on the jig assembly 2, making the distribution of each reinforcing bar in the reinforcing cage more uniform and further improving the binding quality of the reinforcing cage.

[0036] Optionally, such as Figure 3 As shown, the support assembly 1 includes a base plate 11, a side plate 12, and two columns 13. The side plate 12 is vertically connected to the base plate 11, and the two columns 13 are respectively connected to the two sides of the side plate 12. A semi-circular mounting groove 121 with an upward opening is provided on the side plate 12, and a first positioning member 21 is connected to the groove wall of the semi-circular mounting groove 121. The base plate 11 and the two columns 13 make the overall structure of the support assembly 1 more stable, further improving the load-bearing capacity of the rebar cage frame and preventing the rebar cage frame from tipping over due to excessive weight. Exemplarily, the first positioning member 21 is welded and fixed to the groove wall of the semi-circular mounting groove 121.

[0037] Furthermore, such as Figure 3 or Figure 4 As shown, the support assembly 1 also includes a stiffening plate 14, which is disposed between the base plate 11 and the side plate 12, and is perpendicularly connected to both the base plate 11 and the side plate 12. The stiffening plate 14, disposed between the base plate 11 and the side plate 12, further improves the stability of the support assembly 1. Exemplarily, the stiffening plate 14 is welded and fixed to the base plate 11 and the side plate 12.

[0038] For example, the support assembly 1 includes a plurality of stiffening plates 14, which are respectively located on both sides of the side plate 12 along the thickness direction, and the plurality of stiffening plates 14 located on the same side of the side plate 12 are spaced apart. The plurality of stiffening plates 14 can provide support force to the support assembly 1 from both sides of the side plate 12, thereby further enhancing the stability and load-bearing capacity of the support assembly 1.

[0039] Optionally, such as Figure 4 As shown, the support assembly 1 also includes anchoring steel bars 15, which are connected to the base plate 11 and extend vertically, extending at least partially downward beyond the base plate 11. The anchoring steel bars 15 are anchored to the ground, thereby further enhancing the stability and load-bearing capacity of the support assembly 1.

[0040] Specifically, multiple anchoring bars 15 are provided, and the multiple anchoring bars 15 are symmetrically distributed on the base plate 11. The base plate 11 of the support assembly 1 is anchored to the ground by multiple anchoring bars 15, which further enhances the stability and load-bearing capacity of the support assembly 1.

[0041] For example, both the support assembly 1 and the jig assembly 2 are made of steel. Steel has strong resistance to deformation, which can effectively prevent deformation or tipping of the jig caused by excessive weight of the steel cage. For example, the base plate 11, side plates 12 and stiffening plates 14 can be steel plates, and the column 13 can be channel steel.

[0042] Furthermore, such as Figure 4 As shown, the support assembly 1 also includes a connecting part 16, which has a through hole. The support assembly 1 can be connected to the external support through the connecting part 16. It can be understood that the support assembly 1 can be bolted to the external support through the through hole in the connecting part 16, thereby preventing the steel cage frame from tipping over during the process of binding and removing the steel cage.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
