Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a device for quickly making a steel reinforcement ring. Background Art

[0002] Construction projects are a general term for all types of buildings and engineering facilities that provide the material and technological foundation for human life and production. Construction projects are organized, purposeful, and large-scale economic activities. Based on their physical attributes, construction projects can be categorized into three types: architectural engineering, civil engineering, and mechanical and electrical engineering. Construction projects are organized, purposeful, and large-scale economic activities. They are engineering projects that generate comprehensive production capacity or maximize project benefits during the reproduction of fixed assets. Construction projects refer to the construction of new or the renovation of existing fixed assets.

[0003] In the construction industry, on-site reinforcement rings for steel cages are often produced using rebar bending machines. These machines often require skilled technicians to perform the bending, and the lack of a fixed mold results in the rings often failing to meet ovality requirements and making it difficult to control the bend length and angle. Furthermore, rebar bending machines are bulky and difficult to move, requiring dedicated on-site storage areas, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the present invention is to overcome the problems raised in the above-mentioned background technology and provide a device for quickly making steel reinforcement rings, which can effectively improve construction efficiency, effectively realize the hoop winding without falling off the coil, and effectively control the length of the bend hook and the bending angle.

[0005] The purpose of this utility model is mainly achieved through the following technical solutions:

[0006] The invention relates to a device for rapidly producing a steel reinforcement ring, comprising a retaining ring, wherein the retaining ring has a bearing disposed at its center, and a plurality of reinforcing steel plates are disposed between the bearing and the inner wall of the retaining ring, and the ends of the reinforcing steel plates are fixed to the outer wall of the bearing and the inner wall of the retaining ring, respectively. The inner ring of the bearing has a connecting shaft disposed therein, and the connecting shaft is capable of rotating about its own axis. The ends of the connecting shaft extending beyond the bearing are connected to support rods, and the retaining ring is located between the support rods. The support rods are provided with rollers capable of rotating about their own axis, and the rollers are located outside the retaining ring and near the outer wall of the retaining ring. Currently, in the field of construction engineering, most on-site reinforcement rings for steel cages are produced using steel bending machines. Steel bending machines are large and inconvenient to move, and require a dedicated storage area on site, which is time-consuming and labor-intensive. In addition, the steel reinforcement rings often need to be used at any time. If they are produced using steel bending machines, the time required to retrieve them is long, which affects construction efficiency. In addition, the steel bending process often requires skilled technicians to perform the bending, and the bending process without a fixed mold results in the ellipticity of most reinforcement rings not meeting the requirements, and the bending length and bending angle are difficult to control. To address the above-mentioned problems, a device for rapidly manufacturing a steel reinforcement ring is designed. The device comprises a retaining ring, which is an annular steel ring with a bearing disposed at its center. The inner ring of the bearing is rotatable. A plurality of reinforcing steel plates are disposed between the bearing and the inner wall of the retaining ring, and the ends of the reinforcing steel plates are fixed to the outer wall of the bearing and the inner wall of the retaining ring, respectively, to secure the bearing. A connecting shaft is disposed in the inner ring of the bearing, which is rotatable about its own axis. The ends of the connecting shaft extending out of the bearing are connected to support rods. The retaining ring is positioned between the support rods, thereby enabling relative rotation between the retaining ring and the support rods. The support rods are provided with rollers rotatable about their own axes, and the rollers are located outside the retaining ring and near its outer wall. The steel bar to be bent can pass between the retaining ring and the rollers and fit onto the retaining ring. As the retaining ring and the rollers rotate, the steel bar is formed into an annular structure. The overall construction efficiency is high, and the small components on the retaining ring can be used to ensure that the hoop is wound without falling off the coil, and the length and bending angle of the hook can be effectively controlled.

[0007] Furthermore, the sidewalls of the retaining ring are recessed to form two notches, one of which is larger than the other. The two notches are designed to have different functions. The smaller notch is used as a passage for rebar, with its sidewalls used to confine the rebar. Therefore, the opening size of this notch is only slightly larger than the diameter of the rebar. The larger notch, while also a passage for rebar, has to accommodate the dimensional changes of the rebar when it is bent into a loop, that is, the dimensional changes during the process of bending the straight rebar into a reinforcing loop. Therefore, the opening size of this notch is larger to accommodate this change, and the depth of the notch is kept as consistent as possible.

[0008] Furthermore, the reinforcing steel plate is equipped with several positioning shafts, one of which is close to the bearing and another close to the smaller notch. These positioning shafts can be used to position the ends of the steel bars, thereby achieving dimensional control. Furthermore, the positioning shaft close to the notch can form a transition bend in the steel bar to form the required curvature, avoiding bending deformation or substandard performance caused by the right angle of the notch.

[0009] Furthermore, the positioning shafts are perpendicular to the reinforcing steel plates. This allows the steel bars and the positioning shafts to remain perpendicular, preventing them from slipping when in contact, thus ensuring safety during fabrication.

[0010] Furthermore, the retaining ring is provided with a through hole, through which the steel bar can pass through and then bend along the outer wall of the retaining ring to form a stress point, so that the hoop does not fall off the coil and the length of the bend and the bending angle are effectively controlled.

[0011] In summary, compared with the prior art, the present invention has the following beneficial effects: in this solution, the steel bars that need to be bent can pass through between the guard ring and the roller and fit on the guard ring. As the guard ring and the roller rotate, the steel bars are formed into a ring structure, and the overall construction efficiency is high. At the same time, the small components on the guard ring can be utilized to prevent the hoop from falling off the coil, and the length of the bend hook and the bending angle can be effectively controlled.

They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0019] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components.

[0020] like Figure 1 and Figure 2 As shown, a rapid production device for a steel reinforcement ring of the present embodiment includes a guard ring 1, which is an annular steel ring. A bearing is arranged at the center of the guard ring 1. The bearing can be an ordinary ball or needle bearing. The inner ring of the bearing can rotate. A plurality of reinforcing steel plates 2 are arranged between the bearing and the inner wall of the guard ring 1, and the two ends of the reinforcing steel plates 2 are respectively fixed to the outer wall of the bearing and the inner wall of the guard ring 1, so that the bearing is fixed. By using a connecting shaft arranged in the inner ring of the bearing, the connecting shaft and the inner ring of the bearing are fixed, so that the connecting shaft can rotate around its own axis. The ends of the connecting shaft extending out of the bearing are connected to support rods 3, that is, there are two support rods 3, which are respectively fixed and parallel to the ends of the connecting shaft. The guard ring 1 is located between the support rods 3, and a roller 4 that can rotate around its own axis is provided on the support rod 3, and the roller 4 is located outside the guard ring 1 and close to the outer wall of the guard ring 1. The gap between the roller 4 and the outer wall of the retaining ring 1 is the space for the steel bar to pass through. The roller 4 is used to press the steel bar to bend along the outer wall of the retaining ring 1. At this time, one end of the steel bar needs to be fixed, so a through hole 9 is provided on the retaining ring 1. Figure 1 As shown, through the through hole 9 provided on the retaining ring 1, the steel ring 6 can pass through the through hole 9, and then bend along the outer wall of the retaining ring 1 to form a force point, so that the hoop will not fall off the coil, and the length of the hook and the bending angle are effectively controlled.

[0021] The side wall of the guard ring 1 is concave to form two notches, and the size of one notch is larger than the size of the other notch. The larger notch is named the long notch 8, and the smaller notch is named the short opening 5. The short opening 5 is used as a passage for the steel ring 2 10, and its side wall is used to limit the steel ring 2 10, so the opening size of the short opening 5 is only slightly larger than the diameter of the steel bar. Although the long notch 8 is also a passage for the steel bar, it has to bear the dimensional change when the steel bar is bent into a ring, that is, the dimensional change in the process of bending the straight steel bar into a reinforcement ring. Therefore, the opening size of the long notch 8 is larger to accommodate the change process, and the depth of the notch is as consistent as possible.

[0022] Several positioning shafts 7 are provided on the reinforcing steel plate 2, one of which is located near the bearing and another near the smaller notch. The positioning shafts 7 allow the ends of the steel bars to be positioned, thereby achieving dimensional control. Furthermore, the positioning shafts 7 near the notch allow for an overbending of the steel bar, forming the desired curvature and avoiding bending deformation or substandard steel due to the right angle of the notch. The positioning shafts 7 are all perpendicular to the reinforcing steel plate 2. This allows the steel bar and the positioning shafts 7 to remain perpendicular, preventing them from slipping when in contact, thus ensuring safety during production.

[0023] This solution involves the construction technology of pile foundation reinforcement rings, which effectively controls the length and angle of the ring's hooks. It is effectively applicable to the production of reinforcement cages for bored cast-in-place piles and support piles in the construction industry, and can effectively demonstrate the device's functionality within the limited space of a construction site.
