Description

Technical Field

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

[0002] In the field of construction engineering, reinforcing cages are an important component of concrete structures such as pile foundations and bridge piers, and their processing quality directly affects the overall structural strength and stability of the project. Reinforcing cages are typically welded together from longitudinal reinforcing bars and circular stirrups, with the processing precision of the circular rings being one of the key factors in ensuring the quality of the reinforcing cage.

[0003] Currently, the processing of the rings in steel cages is mostly done manually on-site: operators bend the steel bars into shape according to the designed diameter of the steel cage, and then weld them together to form a ring structure. This processing method relies on manual experience, which is not only inefficient, but also makes it difficult to ensure the consistency and accuracy of the ring dimensions. It is prone to problems such as irregular rings and diameter deviations, which in turn affect the overall quality of the steel cage.

[0004] To improve the machining accuracy of the reinforcing cage rings, the industry has gradually adopted jig-based machining aids. However, most existing reinforcing cage jigs are fixed structures with fixed dimensional parameters (such as the diameter and length of the compatible reinforcing cage). When different sizes of reinforcing cages need to be machined in a project, the existing fixed jigs cannot be flexibly adjusted, requiring the redesign and fabrication of new jig devices. This not only increases equipment investment costs and prolongs the construction preparation cycle but also leads to a large number of old jigs being idle and wasted, failing to meet the requirements of equipment versatility and economy in modern engineering construction.

[0005] Furthermore, the standardized design of fixed-type rebar jigs makes it difficult to quickly switch and adjust when processing rebar cages of different specifications, thus limiting the improvement of construction efficiency. This is especially true in large-scale projects where rebar cages come in various sizes and are produced in large batches, where the aforementioned shortcomings of fixed-type jigs become more prominent, becoming a significant factor restricting the standardized and efficient production of rebar cages. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a steel cage construction formwork to solve the problems mentioned above in the background art.

[0007] A steel cage construction jig includes a mounting base, a jig body, and a connecting structure for detachably mounting the jig body on the mounting base;

[0008] The connecting structure includes a limiting groove formed at the top of the mounting base and extending through both ends of the mounting base, a connecting block fixedly connected to the bottom of the fixture body and detachably disposed within the limiting groove, first positioning blocks detachably disposed at both ends of the limiting groove, and a first fixing member connected to the connecting block; the two first positioning blocks are used to close the openings at both ends of the limiting groove and respectively abut against the corresponding ends of the connecting block located in the limiting groove, thereby initially fixing the connecting block within the limiting groove, and the first fixing member is used to further fix and limit the initially positioned connecting block within the limiting groove.

[0009] Compared to existing technologies, the advantages of this application are as follows: Through a detachable connection structure (the cooperation of a limiting groove, connecting block, first positioning block, and first fixing component), the main body of the jig can be easily disassembled and replaced from the mounting base, solving the problem that traditional fixed jigs have fixed dimensions and cannot adapt to the processing of rebar cages of different specifications. When the size of the rebar cage changes, it is not necessary to remake the entire jig; only a suitable jig main body needs to be replaced or the position of the connecting block adjusted, significantly reducing equipment investment costs and improving the versatility of the jig.

[0010] Furthermore, the two ends of the connecting block extend into a second positioning block away from the main body of the fixture, so that the second positioning block and the main body of the fixture form an operating space, and the second positioning block is fixed on the mounting base by the first fixing member.

[0011] Furthermore, the second positioning block has a positioning strip extending from the end away from the connecting block, and the first positioning block has a positioning groove at the end near the connecting block, the positioning groove being adapted to the positioning strip.

[0012] Furthermore, a plurality of rollers are arranged along the length of the mounting base; the top surface of the plurality of rollers is flush with the bottom surface of the limiting groove, so that the connecting block contained in the limiting groove can move on the rollers toward the end of the limiting groove.

[0013] Furthermore, the mounting base includes a base and support legs disposed at both ends of the bottom of the base.

[0014] Furthermore, the first positioning block is provided with a threaded hole, through which a second fixing member passes and is threadedly connected to the mounting base, so as to press and fix the first positioning block in the limiting groove.

[0015] Furthermore, the cross-sectional shape of the limiting groove is dovetail-shaped.

[0016] Furthermore, the main body of the fixture includes a lower fixture and an upper fixture, and both the lower fixture and the upper fixture are provided with a plurality of mounting holes. Attached Figure Description

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figures 1 to 2The image shows a steel cage construction jig in an embodiment of the present invention, comprising a mounting base 10, a jig body 20, and a connecting structure 30. The connecting structure 30 is used to detachably mount the jig body 20 on the mounting base 10 to adapt to the processing requirements of steel cages of different sizes.

[0026] The connecting structure 30 is the core component for detachably connecting the fixture body 20 and the mounting base 10. Specifically, it includes a limiting groove 31, a connecting block 32, a first positioning block, and a first fixing member 34. The limiting groove 31 is located at the top of the mounting base 10 and extends through both ends, providing a channel for the installation and movement of the connecting block 32. The connecting block 32 is fixedly connected to the bottom of the fixture body 20 and can be detachably mounted within the limiting groove 31, serving as a bridge connecting the fixture body 20 and the mounting base 10. Two first positioning blocks are detachably mounted at both ends of the limiting groove 31. Their function is to close the openings at both ends of the limiting groove 31 and abut against the corresponding ends of the connecting block 32 located within the limiting groove 31, thereby initially fixing the connecting block 32 within the limiting groove 31.

[0027] Meanwhile, the first positioning block is provided with a threaded hole 331, through which the second fixing member 332 passes and is threadedly connected to the mounting base 10, which can press and fix the first positioning block in the limiting groove 31, further enhancing the stability of the initial positioning. The first fixing member 34 is connected to the connecting block 32, and is used to fix and limit the connecting block 32 in the limiting groove 31 after the initial positioning, ensuring that the connecting block 32 will not be displaced during processing. Both the first fixing member 34 and the second fixing member 332 can be fixing bolts.

[0028] Furthermore, second positioning blocks 35 extend from both ends of the connecting block 32 away from the fixture body 20, creating an operating space 351 between the second positioning blocks 35 and the fixture body 20. This facilitates tool access and allows operators to perform tasks such as bolt tightening. Moreover, a positioning strip 352 extends from the end of the second positioning block 35 away from the connecting block 32, and a positioning groove 353, adapted to the positioning strip 352, is provided at the end of the first positioning block near the connecting block 32. When the first positioning block is installed in place, the positioning strip 352 is embedded in the positioning groove 353, achieving precise positioning.

[0029] Furthermore, a plurality of rollers 36 are arranged along the length of the mounting base 10; the top surface of the plurality of rollers 36 is flush with the bottom surface of the limiting groove 31, so that the connecting block 32, which is accommodated in the limiting groove 31, can move on the rollers 36 toward the end of the limiting groove 31. This design allows the connecting block 32, which is accommodated in the limiting groove 31, to move on the rollers 36 toward the end of the limiting groove 31, changing the sliding friction of the connecting block 32 into rolling friction, reducing the moving resistance, and making it easier for the operator to adjust the position of the connecting block 32.

[0030] Please see Figures 3 to 4 As shown, the mounting base 10 further includes a horizontally arranged base 11 and support legs 12 symmetrically fixed to both ends of the bottom of the base 11. The base 11 is formed by welding of steel profiles, and a limiting groove 31 extending through both ends is provided on its top along the length direction. The cross-section of the limiting groove 31 is dovetail-shaped, and the groove width gradually decreases from the groove opening to the groove bottom, which can effectively prevent the connecting block 32 from detaching.

[0031] Specifically, the main body 20 of the jig includes a lower jig 21 and an upper jig 22, both of which are rectangular frame structures made of welded steel plates. Multiple mounting holes 23 are arranged on the sides of both the lower jig 21 and the upper jig 22, the spacing of which can be determined according to the diameter requirements of the reinforcing cage ring. The bottom of the lower jig 21 is welded and fixed to the connecting block 32 of the connecting structure 30. The upper jig 22 is detachably connected to the lower jig 21 via a snap-fit ​​structure (not shown in the figure), facilitating material removal after the reinforcing cage is processed.

[0032] When processing steel cages of different diameters, it is necessary to replace the main body 20 of the jig with one of the appropriate size. The specific operating steps are as follows:

[0033] 1. Use a wrench to loosen and remove the first fixing member 34 (such as a fixing bolt) on the connecting block 32 in sequence, so that the rigid connection between the connecting block 32 and the base 11 of the mounting seat 10 is separated; then loosen the second fixing member 332 (such as an M16 bolt) on the first positioning block, and remove one or both of the first positioning blocks from both ends of the limiting groove 31 to release the end limit of the connecting block 32.

[0034] 2. The operator pushes the old jig body 20 along the length of the limiting groove 31. Due to the rolling action of the roller 36 inside the mounting base 10, the jig body 20 can slide easily until the connecting block 32 is completely disengaged from the opening of the limiting groove 31, and the old jig body 20 is moved to the storage area as a whole.

[0035] 3. Based on the diameter specifications of the new steel cage, select the corresponding size jig body 20 (lower jig 21 and upper jig 22), check whether its connecting block 32 is compatible with the limiting groove 31 of the mounting seat 10 (such as the matching degree of the dovetail structure), and confirm that the spacing of the mounting holes 23 of the upper and lower jigs 21 matches the size of the ring to be processed.

[0036] 4. Align the connecting block 32 at the bottom of the new fixture body 20 with the opening end of the limiting groove 31 of the mounting seat 10, and slowly push it into the limiting groove 31. With the help of the rolling of the roller 36, move the fixture body 20 to the preset processing position (against one of the unremoved first positioning blocks), ensuring that its center line is aligned with the length direction of the mounting seat 10.

[0037] 5. Install the first positioning block at both ends of the limiting groove 31, so that the positioning groove 353 of the first positioning block is precisely engaged with the positioning strip 352 extending from the connecting block 32 (ensuring no loose gap), and then tighten the second fixing member 332 to press the first positioning block onto the mounting base 10, thus completing the limiting of both ends of the connecting block 32.

[0038] 6. By screwing the first fixing member 34 into the operating space 351, the second positioning block 35 of the connecting block 32 is tightly fitted with the base 11 of the mounting seat 10, ensuring that the jig body 20 has no displacement deviation under stress, and completing the fixed installation of the new jig body 20.

[0039] In summary, the steel cage construction formwork in the above embodiments of this utility model has the following beneficial effects:

[0040] Through the detachable connection structure 30 (the cooperation of the limiting groove 31, connecting block 32, first positioning block, and first fixing member 34), the jig body 20 can be easily disassembled and replaced from the mounting base 10, solving the problem that traditional fixed jigs have fixed dimensions and cannot adapt to the processing of steel cages of different specifications. When the size of the steel cage changes, there is no need to remake the entire jig; only the appropriate jig body 20 needs to be replaced or the position of the connecting block 32 needs to be adjusted, significantly reducing equipment investment costs and improving the versatility of the jig.

[0041] The connecting block 32 is initially fixed by limiting the two ends of the first positioning block, and then further reinforced by the first fixing member 34. Combined with the cooperation structure of the second positioning block 35 with the positioning strip 352 and positioning groove 353 of the first positioning block, it ensures that the jig body 20 is stable and does not shift during processing. Compared with manual bending and welding, this method effectively improves the dimensional consistency and processing accuracy of the skeleton ring, and reduces quality problems caused by human error.

[0042] The roller 36 design within the mounting base 10 allows the connecting block 32 to move smoothly along the limiting groove 31, facilitating quick adjustment of the jig body 20's position. The detachable first positioning block and the modular jig body 20 structure (lower jig 21 and upper jig 22) simplify the disassembly and replacement process. Compared to the cumbersome adjustment method of traditional fixed jigs, this significantly shortens the switching time for processing different specifications of rebar cages, improving construction efficiency.

[0043] The dovetail-shaped limiting groove 31 provides reliable constraint to the connecting block 32, and works in conjunction with the second fixing member 332 of the first positioning block to tighten the structure, ensuring that the jig body 20 is stable and reliable during welding operations and other stress processes. The base 11 and support legs 12 of the mounting seat 10 are designed to further enhance the overall structural load-bearing capacity and reduce safety hazards during construction.

[0044] By reusing components (such as the mounting base 10, which can be used for a long time, with only the jig body 20 to be replaced), the problem of traditional fixed jigs being scrapped due to size changes is avoided, reducing material waste. At the same time, the standardized mounting hole 23 design facilitates the universal production and maintenance of the jig body 20, indirectly reducing the overall cost of engineering construction.
