[0002] Reinforcing cages are a common structure used in building construction to enhance the tensile stress of concrete structures and improve the stability and load-bearing capacity of the foundation.

[0003] The reinforcing cage consists of tightening hoops, main bars, and spiral hoops. In the fabrication of reinforcing cages, especially cylindrical ones, it is necessary to ensure the concentricity of the main bars so that the reinforcing cage is subjected to uniform stress after concrete pouring. Therefore, there is an urgent need for a reinforcing bar positioning structure that can ensure high concentricity. Utility Model Content

[0004] The purpose of this utility model is to provide a rebar positioning structure for construction, to solve the problem mentioned in the background art of ensuring the concentricity of the main bars during the fabrication of rebar cages, especially cylindrical rebar cages. To achieve the above objective, this utility model provides the following technical solution: a rebar positioning structure for construction, including support legs, a fixing component inside a circle formed by multiple support legs, a limiting component inside the fixing component, a rotating component inside the limiting component, a movable component at the top of the rotating component, and a snap-fit ​​component on one side of the movable component;

[0005] The fixing component includes connecting ears, which are fixedly connected to the top of the support leg and the side surface of the support leg is also fixedly connected to connecting ears. Multiple connecting ears are arranged in a circle and a fixing ring is fixedly connected to the side near the center of the circle. The top of the fixing ring is provided with a ring groove, and the bottom of one of the fixing rings is provided with multiple arc grooves arranged in a ring and completely penetrating the fixing ring.

[0006] More preferably, an extension piece is fixedly connected to the inner ring surface of the fixing ring, a fixing shaft is fixedly connected to the top of the extension piece, a lower clamping piece is fixedly sleeved on the side surface of the fixing shaft, and an upper clamping piece is fixedly connected to the top of the fixing shaft.

[0023] Please see Figures 1-7 This utility model provides a technical solution: a steel bar positioning structure for construction, including support legs 1, a fixing component 2 is provided inside the circle formed by multiple support legs 1, a limiting component 3 is provided inside the fixing component 2, a rotating component 4 is provided inside the limiting component 3, a movable component 5 is provided on the top of the rotating component 4, and a snap-fit ​​component 6 is provided on one side of the movable component 5.

[0024] The fixing component 2 includes a connecting ear 201, which is fixedly connected to the top of the support leg 1 and the side surface of the support leg 1 is also fixedly connected to the connecting ear 201. Multiple connecting ears 201 are arranged in a circle and a fixing ring 202 is fixedly connected to the side near the center of the circle. The top of the fixing ring 202 is provided with a ring groove 203, and the bottom of one of the fixing rings 202 is provided with multiple arc grooves 204 arranged in a ring and the arc grooves 204 completely penetrate the fixing ring 202.

[0025] In this embodiment, as Figure 2 and Figure 4As shown, an extension piece 301 is fixedly connected to the inner ring surface of the fixing ring 202, a fixing shaft 302 is fixedly connected to the top of the extension piece 301, a lower clamping piece 303 is fixedly sleeved on the side surface of the fixing shaft 302, and an upper clamping piece 304 is fixedly connected to the top of the fixing shaft 302.

[0026] In this embodiment, as Figure 1 and Figure 3 As shown, the rotating assembly 4 includes a movable ring 401, which is movably sleeved in the ring groove 203. A connecting rod 403 is fixedly connected to one side of the two movable rings 401 facing each other. A convex shaft 402 is fixedly connected to the top of the movable rings 401, and a throttle 404 is fixedly connected to the top of one of the movable rings 401.

[0027] In this embodiment, as Figure 5 , Figure 6 and Figure 7 As shown, the movable component 5 includes a rotating handle 501. One end of the rotating handle 501 is hinged to the convex shaft 402. A sliding groove 502 is provided inside the rotating handle 501. The rotating handle 501 is located between the lower clamping plate 303 and the upper clamping plate 304, and the fixed shaft 302 is movably connected in the sliding groove 502. The other end of the rotating handle 501 is fixedly connected to a hinge piece 503, and the hinge piece 503 is hinged to a hinge ring 504.

[0028] In this embodiment, as Figure 5 , Figure 6 and Figure 7As shown, the snap-fit ​​assembly 6 includes an auxiliary piece 601, which is fixedly connected to one end of the hinge ring 504. A clearance groove 602 is provided at the edge of the inner ring of the hinge ring 504. A snap-fit ​​groove 603 is provided on one side of the inner wall of the clearance groove 602. A protrusion 605 is snapped into the inside of the snap-fit ​​groove 603. A snap-fit ​​piece 604 is fixedly connected to one side of the protrusion 605 and is fixedly connected to one side of the hinge piece 503. In use, the handle 404 is first rotated according to the required radius. Simultaneously, the handle 404 rotates, driving the two movable rings 401 to rotate via the connecting rod 403. Since the handle 501 achieves hinge with the movable rings 401 through the protruding shaft 402 and the fixed shaft 302... The process involves rotating multiple handles 501 around the convex shaft 402 to synchronously adjust the radius of the circle. After adjustment, the reinforcing bar 7 is placed in the collar formed by the hinge plate 503 and the hinge ring 504. The snap-fit ​​groove 603 and the protrusion 605 are snapped together by elastic deformation. After the tightening hoop and spiral stirrup are welded, the hinge ring 504 is deformed by moving the auxiliary plate 601, thereby disengaging the snap-fit ​​groove 603 and the snap-fit ​​plate 604, releasing the restraint on the reinforcing bar 7, and separating the formed reinforcing bar cage from the positioning device. The rotation of the movable ring 401 causes the handle 501 to rotate, thereby moving multiple collars synchronously. This allows for the production of reinforcing bars of different diameters, thereby improving concentricity and expanding the applicability.

[0029] In this embodiment, as Figure 1 and Figure 5 As shown, the hinge ring 504 and the hinge piece 503 are connected to form a collar structure, and the collar structure is movably sleeved with steel bars 7, and multiple steel bars 7 are distributed in a ring array.

[0030] The method of use and advantages of this utility model: The working process of this steel bar positioning structure during construction is as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, during use, first rotate the handle 404 according to the required radius. While the handle 404 rotates, the connecting rod 403 drives the two movable rings 401 to rotate together. Since the rotating handle 501 is hinged to the movable ring 401 through the convex shaft 402 and the fixed shaft 302, multiple rotating handles 501 rotate around the convex shaft 402 as the center, thereby synchronously adjusting the radius of the circle formed. After the adjustment is completed, the reinforcing bar 7 (i.e., the main bar) is placed in the collar formed by the hinge plate 503 and the hinge ring 504, and the snap-fit ​​groove 603 and the protrusion 605 are snapped together by elastic deformation. After the tightening hoop and spiral hoop are welded, the hinge ring 504 is deformed by moving the auxiliary plate 601, thereby disengaging the snap-fit ​​groove 603 and the snap-fit ​​plate 604, releasing the restraint on the reinforcing bar 7, and separating the formed reinforcing cage from the positioning device.
