Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, specifically a steel reinforcement support frame. Background Technology
[0002] In reinforced concrete structure construction, the binding of reinforcing bars for beams, slabs, columns, and other components is a core process. Traditional reinforcing bar binding mainly relies on manual placement of longitudinal and transverse reinforcing bars on-site, followed by manual binding with wire to form a reinforcing bar jig. This construction method has significant efficiency bottlenecks and potential quality risks.
[0003] First, manual rebar tying relies entirely on workers' physical strength and experience, resulting in high labor intensity and slow speed. This is especially true in large-span, high-density rebar projects, where tying work accounts for a significant portion of the total construction time, becoming a key factor restricting construction progress. Second, manually fixed rebar joints have poor stability. Under the impact and vibration of subsequent concrete pouring, they are prone to displacement, subsidence, or deformation, leading to uneven rebar cover thickness and directly affecting the structure's load-bearing capacity and durability. Furthermore, the large amount of wire consumed not only increases material costs, but its sharp ends also pose a safety hazard on the construction site.
[0004] To improve efficiency, existing technologies use simple trestles, ladders, or prefabricated supports with slots to fix reinforcing bars. However, these devices still have significant shortcomings in practical applications. On the one hand, they lack versatility, often designed for reinforcing bars with specific spacing and diameters. When engineering designs change or different specifications of reinforcing bars need to be handled, a large number of accessories need to be customized or adjusted, resulting in poor adaptability. On the other hand, the "fixing" function of existing devices is mostly limited to support and positioning; the intersections between reinforcing bars still require a large amount of manual binding to complete the final connection, failing to fundamentally reduce the amount of binding work.
[0005] Therefore, there is an urgent need in this field for an innovative steel reinforcement support system that can not only significantly improve work efficiency, but also reduce construction costs through the standardization and reusability of tools. Summary of the Invention
[0006] The purpose of this invention is to provide a steel bar support frame to solve the problems raised in the prior art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a rebar support frame, the rebar support frame including a bracket, a movable bracket installed on the inner side of the bracket, movable mounting plates symmetrically installed on the bracket, a fixed mounting plate installed between the two movable mounting plates, a straight groove opened on the movable mounting plate, a plurality of clamping members installed in the straight groove, and a plurality of grooves opened on the fixed mounting plate, a pressing member installed in the groove; The bracket has symmetrical track grooves on both sides, and a lead screw is installed in the track groove. The lead screw is connected by a transmission belt, and one of the lead screws is connected to the output end of a motor. The motor is fixedly installed on the bracket.
[0008] As a preferred technical solution, the fixed mounting plate is located inside the track groove. The fixed mounting plate has several grooves equidistantly spaced. A pressing hole is provided at the bottom of the groove. A pressing chamber is also provided in the pressing hole. A pressing spring is provided in the pressing chamber.

One end of the locking block is connected to the locking chamber by a locking spring. The other end of the locking block is provided with an inclined surface. Rotating shafts are provided on both sides outside the groove. Right-angle clamps are rotatably connected to the rotating shafts.
[0009] As a preferred technical solution, the pressing component includes a pressing rod and a pressing plate. The pressing rod is rotatably connected to the pressing plate. A movable block is symmetrically arranged at the top of the pressing rod, and a fixed block is symmetrically arranged at the bottom of the pressing plate. The included angle between the movable block and the fixed block is 90°. The movable block and the fixed block are connected by an arc spring. A locking groove is symmetrically opened at the bottom of the pressing rod, and a pressing post is arranged on one side of the pressing plate.
[0010] As a preferred technical solution, the movable mounting plate is connected to both of the lead screws simultaneously, and a plurality of mounting bosses are provided on the inner side of the movable mounting plate, and a mounting groove is provided in the gap between the two mounting bosses.
[0011] As a preferred technical solution, the clamping member includes a connecting rod, one end of which is embedded in the straight groove, and the other end of which is provided with an annular groove. A plurality of clamping rods are embedded in the annular groove, one end of which is provided with an arc-shaped plate, and the other end of which is provided with a rotating gripper.

[0013] As a preferred technical solution, the bottom of the movable support is provided with a pulley, the pulley is placed on the track, and the rest of the structure of the movable support is the same as that of the support.
[0014] As a preferred technical solution, a number of steel bars are placed horizontally and vertically between the two movable mounting plates and the fixed mounting plate, and the steel bars are fixed on the bracket by the clamping member and the pressing member.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The movable mounting plates at both ends of the bracket can be adjusted by a motor to change the distance between the two movable mounting plates, which can accommodate the installation of steel bars of different lengths. There is no need to bend the steel bars, which reduces the labor intensity of the workers. The grooves and mounting slots can firmly fix the steel bars on the bracket and ensure that the spacing between adjacent steel bars is consistent. This ensures sufficient work efficiency while improving the connection strength of the steel bars. 2. When the reinforcing bar is placed in the groove, the pressing component will be pressed into the pressing hole. As the pressing component is pressed down, it will drive the right-angle clamp to rotate, thereby fixing the reinforcing bar through the right-angle clamp. The pressing component is fixed by the locking block during the pressing process and cannot move, thus realizing the fixing of the reinforcing bar by the fixed installation plate. 3. The mounting slot can fix the steel bars on one side of the movable mounting plate, and the angle and orientation of the clamps on the clamping parts can be adjusted arbitrarily, which can fix the intersection points formed by steel bars placed at any angle, further ensuring the stability of the steel bars.

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example: Figures 1-7As shown, the present invention provides a technical solution for a rebar support frame, which includes a support 1, a movable support 2 installed inside the support 1, movable mounting plates 3 symmetrically installed on the support 1, and a fixed mounting plate 4 installed between the two movable mounting plates 3. The movable mounting plates 3 have straight grooves 32, and several clamping components 5 are installed in the straight grooves 32. The fixed mounting plate 4 has several grooves 41, and pressing components 6 are installed in the grooves 41. Track grooves 11 are symmetrically opened on both sides of the support 1, and lead screws 12 are installed in the track grooves 11. The lead screws 12 are connected by a transmission belt 13, and one lead screw 12 is connected to the output end of a motor 14. The motor 14 is fixedly installed on the support 1. First, the distance between the two movable mounting plates 3 is determined according to the length of the rebar. After measuring and determining the length of the rebar, the motor 14 is started, driving the transmission belt 13 at the output end to rotate, thereby ensuring that the lead screws 12 on both sides of the support 1 rotate synchronously, thus realizing the horizontal movement of the movable mounting plates 3 on the support 1. When the distance between the two movable mounting plates 3 is consistent with the rebar, the motor 14 is turned off. The bottom row of reinforcing bars in the steel cage is placed into the groove 41 of the fixing plate 4. During the process of placing the reinforcing bars into the groove 41, the pressing member 6 in the groove 41 is pressed into the pressing hole 42. At the same time as the pressing member 6 is pressed down, the pressing column 6202 at the front end of the pressing plate 62 will also move the end of the right-angle clamp 47, thereby driving the right-angle clamp 47 to rotate. When the pressing member 6 is fully pressed into the pressing hole 42, the side of the right-angle clamp 47 rotates to be parallel to the side of the groove 41. Through the cooperation of the two right-angle clamps 47, the reinforcing bars can be fixed at the right angle. Inside the clamping plate 47, and when the pressing member 6 is fully pressed in, the locking chamber 44 communicates with the locking groove 6103 on the pressing member 6. The locking block 45 inside the locking chamber 44 is driven by the locking spring 4401 to embed into the locking groove 6103, completely fixing the pressing rod 6, thereby fixing the reinforcing bar. Furthermore, the pressing plate 62 and the pressing hole 42 have the same shape. During the subsequent use of the reinforcing bar, concrete and dust cannot enter the pressing hole 42, thus avoiding damage to the internal parts of the pressing hole 42 and the pressing member 6.
[0020] After the bottom layer of reinforcing bars is fixed, the second layer of reinforcing bars needs to be staggered with the bottom layer. Therefore, the second layer of reinforcing bars can be embedded in the mounting groove 33 for fixing. The distance between the two movable mounting plates 3 has been determined based on the length of the reinforcing bars at the beginning, so the reinforcing bars can be securely installed between the movable mounting plates 3 to prevent them from moving. In order to further improve the stability of the reinforcing bars on the bracket 1, the reinforcing bars of the two adjacent layers need to be fixed. At this time, by moving the clamping member 5 in the straight groove 32, it is ensured that the intersection of the clamping member 5 and the two adjacent layers of reinforcing bars is at the same horizontal level. Then, the clamping member 5 is fixed in the straight groove 32. Since the clamping rod 53 can rotate freely along the annular groove 52 through the cooperation of the arc plate 5301 and the annular groove 52, one of the clamping rods 5 is first moved. 3. Place the rack vertically downwards and adjust the direction of the rotating jaw 5302 to clamp the bottommost rebar. Then, adjust the angle of the other clamp 53 and clamp the second layer of rebar with the rotating jaw 5302 on the other clamp 53. This connects the two adjacent layers of rebar, further improving the connection strength. Multiple layers of rebar can be installed on the bracket 1 as needed. Then, repeat the above steps and use the clamping part 5 to fix all the rebars. By using the clamping part 5, you only need to embed the rotating jaw 5302 into the rebar to make a connection, avoiding manual binding with wire, which greatly saves labor costs. In addition, wire is a disposable workpiece with low recycling value, while the clamping part 5 can be recycled and reused after use, which can reduce construction costs.
[0021] After the reinforcing bars are used, they need to be removed. First, the clamping piece 5 at the connection intersection needs to be removed, and then the reinforcing bars placed at the top are removed layer by layer until only the bottom reinforcing bar remains. Since the bottom of the pressing piece 6 protrudes from the fixing plate 4 when it is fixed, the bottom of the pressing piece 6 is rotated. During the rotation of the pressing piece 6, the side wall of the locking groove 6103 presses the side 4501 of the locking block 45 until the locking block 45 is pressed back into the locking chamber 44. At this time, the pressing piece 6 loses the limit of the locking block 45, and the pressing column 6202 can no longer fix the right angle clamp 47. At this time, the bottom reinforcing bar can be taken out directly. The pressing piece 6 pops out of the pressing hole 42 again under the action of the pressing spring 4301. Thus, the entire process of installing and removing the reinforcing bars on the bracket 1 is completed.
[0022] The movable mounting plate 3 is connected to both lead screws 12. Several mounting bosses 31 are provided on the inner side of the movable mounting plate 3, and mounting grooves 33 are provided in the gap between the two mounting bosses 31.
[0023] The fixed mounting plate 4 is located inside the track groove 11. Several grooves 41 are evenly spaced on the fixed mounting plate 4. A pressing hole 42 is provided at the bottom of each groove 41, and a pressing chamber 43 is provided inside each pressing hole 42. A pressing spring 4301 is provided inside each pressing chamber 43. Locking chambers 44 are symmetrically provided on both sides of the pressing hole 42, and locking blocks 45 are provided inside each locking chamber 44. One end of the locking block 45 is connected to the locking chamber 44 via a locking spring 4401, and the other end of the locking block 45 is provided with an inclined surface 4501. Rotating shafts 46 are provided on both sides outside the grooves 41, and right-angle clamps 47 are rotatably connected to the rotating shafts 46. The bottom row of reinforcing bars of the reinforcing cage is placed into the grooves 41 of the fixed mounting plate 4. During the process of placing the reinforcing bars into the grooves 41… The pressing element 6 in the groove 41 will be pressed into the pressing hole 42. At the same time as the pressing element 6 is pressed down, the pressing column 6202 at the front end of the pressing plate 62 will also push the end of the right angle clamp 47, thereby driving the right angle clamp 47 to rotate. When the pressing element 6 is fully pressed into the pressing hole 42, the side of the right angle clamp 47 rotates to be parallel to the side of the groove 41. Through the cooperation of the two right angle clamps 47, the steel bar can be fixed in the right angle clamp 47. When the pressing element 6 is fully pressed in, the locking chamber 44 is connected to the locking groove 6103 on the pressing element 6. The locking block 45 in the locking chamber 44 is embedded in the locking groove 6103 under the drive of the locking spring 4401, and the pressing rod 6 is completely fixed, thereby realizing the fixing of the steel bar.
[0024] The clamping component 5 includes a connecting rod 51, one end of which is embedded in a straight groove 32, and the other end of which is provided with an annular groove 52. Several clamping rods 53 are embedded in the annular groove 52. One end of each clamping rod 53 is provided with an arc-shaped plate 5301, and the other end of each clamping rod 53 is provided with a rotating gripper 5302. To further improve the stability of the reinforcing bars on the support 1, it is necessary to fix the reinforcing bars of adjacent layers. At this time, by moving the clamping component 5 in the straight groove 32, it is ensured that the intersection point of the clamping component 5 and the reinforcing bars of the adjacent layers is at the same level. In terms of horizontal height, the clamping member 5 is then fixed in the straight groove 32. Since the clamping rod 53 can rotate freely along the annular groove 52 through the cooperation of the arc plate 5301 and the annular groove 52, first, one of the clamping rods 53 is placed vertically downward, the direction of the rotating jaw 5302 is adjusted, and the rotating jaw 5302 is clamped on the bottommost steel bar. Then, the angle of the other clamping rod 53 is adjusted, and the rotating jaw 5302 on the other clamping rod 53 is clamped on the second layer of steel bars, thus realizing the connection between the two adjacent layers of steel bars.
[0025] The pressing component 6 includes a pressing rod 61 and a pressing plate 62. The pressing rod 61 is rotatably connected to the pressing plate 62. A movable block 6101 is symmetrically arranged on the top of the pressing rod 61, and a fixed block 6201 is symmetrically arranged on the bottom of the pressing plate 62. The included angle between the movable block 6101 and the fixed block 6201 is 90°. The movable block 6101 and the fixed block 6201 are connected by an arc spring 6102. A locking groove 6103 is symmetrically opened on the bottom of the pressing rod 61, and a pressing post 6202 is arranged on one side of the pressing plate 62.
[0026] A baffle 15 is provided on one side of the support 1, and a track 16 is provided at the bottom of the support 1. A pulley 21 is provided at the bottom of the movable support 2, and the pulley 21 is placed on the track 16. The rest of the structure of the movable support 2 is the same as that of the support 1.
[0027] Several steel bars are placed horizontally and vertically between the two movable mounting plates 3 and the fixed mounting plate 4. The steel bars are fixed to the bracket 1 by clamping parts 5 and pressing parts 6.
[0028] Working principle of the invention: First, determine the distance between the two movable mounting plates 3 based on the length of the reinforcing bars. After measuring and determining the length of the reinforcing bars, start the motor 14. The motor 14 drives the transmission belt 13 on the output end to rotate, thereby ensuring that the lead screws 12 on both sides of the bracket 1 rotate synchronously, thus realizing the horizontal movement of the movable mounting plates 3 on the bracket 1. When the distance between the two movable mounting plates 3 is consistent with the reinforcing bars, turn off the motor 14. The bottom row of reinforcing bars of the reinforcing cage is placed into the groove 41 of the fixed mounting plate 4. During the process of placing the reinforcing bars into the groove 41, the pressing member 6 in the groove 41 will be pressed into the pressing hole 42. At the same time as the pressing member 6 is pressed down, the pressing column 6202 at the front end of the pressing plate 62 will also push the end of the right angle clamp 47, thereby driving the right angle clamp. 47 rotates. When the pressing member 6 is fully pressed into the pressing hole 42, the side of the right-angle clamp 47 rotates to be parallel to the side of the groove 41. Through the cooperation of the two right-angle clamps 47, the reinforcing bar can be fixed in the right-angle clamp 47. When the pressing member 6 is fully pressed in, the locking chamber 44 communicates with the locking groove 6103 on the pressing member 6. The locking block 45 in the locking chamber 44 is driven by the locking spring 4401 and embedded in the locking groove 6103, completely fixing the pressing rod 6, thereby fixing the reinforcing bar. Furthermore, the pressing plate 62 and the surface of the pressing hole 42 are consistent in shape. During the subsequent use of the reinforcing bar, concrete and dust cannot enter the pressing hole 42, avoiding damage to the internal parts of the pressing hole 42 and the pressing member 6.
[0029] After the bottom layer of reinforcing bars is fixed, the second layer of reinforcing bars needs to be staggered with the bottom layer. Therefore, the second layer of reinforcing bars can be embedded in the mounting groove 33 for fixing. The distance between the two movable mounting plates 3 has been determined based on the length of the reinforcing bars at the beginning, so the reinforcing bars can be securely installed between the movable mounting plates 3 to prevent them from moving. In order to further improve the stability of the reinforcing bars on the bracket 1, the reinforcing bars of the two adjacent layers need to be fixed. At this time, by moving the clamping member 5 in the straight groove 32, it is ensured that the intersection of the clamping member 5 and the two adjacent layers of reinforcing bars is at the same horizontal level. Then, the clamping member 5 is fixed in the straight groove 32. Since the clamping rod 53 can rotate freely along the annular groove 52 through the cooperation of the arc plate 5301 and the annular groove 52, one of the clamping rods 5 is first moved. 3. Place the rack vertically downwards and adjust the direction of the rotating jaw 5302 to clamp the bottommost rebar. Then, adjust the angle of the other clamp 53 and clamp the second layer of rebar with the rotating jaw 5302 on the other clamp 53. This connects the two adjacent layers of rebar, further improving the connection strength. Multiple layers of rebar can be installed on the bracket 1 as needed. Then, repeat the above steps and use the clamping part 5 to fix all the rebars. By using the clamping part 5, you only need to embed the rotating jaw 5302 into the rebar to make a connection, avoiding manual binding with wire, which greatly saves labor costs. In addition, wire is a disposable workpiece with low recycling value, while the clamping part 5 can be recycled and reused after use, which can reduce construction costs.
[0030] After the reinforcing bars are used, they need to be removed. First, the clamping piece 5 at the connection intersection needs to be removed, and then the reinforcing bars placed at the top are removed layer by layer until only the bottom reinforcing bar remains. Since the bottom of the pressing piece 6 protrudes from the fixing plate 4 when it is fixed, the bottom of the pressing piece 6 is rotated. During the rotation of the pressing piece 6, the side wall of the locking groove 6103 presses the side 4501 of the locking block 45 until the locking block 45 is pressed back into the locking chamber 44. At this time, the pressing piece 6 loses the limit of the locking block 45, and the pressing column 6202 can no longer fix the right angle clamp 47. At this time, the bottom reinforcing bar can be taken out directly. The pressing piece 6 pops out of the pressing hole 42 again under the action of the pressing spring 4301. Thus, the entire process of installing and removing the reinforcing bars on the bracket 1 is completed.
[0031] Since the weight of the multi-layer steel bars fixed on the support 1 is large and difficult to move directly, when the steel cage needs to be used flexibly, the steel bars can be installed in the movable support 2 inside the support 1. The movable support 2 can be moved to any position on the track 16 through the cooperation of the pulley 21 at the bottom and the track 16. The rest of the structure of the movable support 2 is completely the same as that of the support 1, which can ensure the stable connection of the steel bars on the movable support 2.
[0032] In actual installation, not all steel bars are straight; some steel bars may be bent. In this case, it is impossible to ensure that the intersections of the steel bars are perpendicular to each other. Ordinary cross connectors cannot securely connect these intersections. However, clamp 5 can be adjusted at any angle, which can connect this type of steel bar and ensure its stability.
[0033] The movable mounting plates 3 at both ends of the bracket 1 can be adjusted by the motor 14, thereby changing the distance between the two movable mounting plates 3. This allows for the installation of steel bars of different lengths without bending them, reducing the labor intensity of workers. The grooves 41 and mounting slots 32 can firmly fix the steel bars to the bracket 1 and ensure that the spacing between adjacent steel bars is consistent, thus improving the connection strength of the steel bars while ensuring sufficient work efficiency.
[0034] When the reinforcing bar is placed in the groove 41, the pressing member 6 will be pressed into the pressing hole 42. As the pressing member 6 is pressed down, it will drive the right angle clamp 47 to rotate, thereby fixing the reinforcing bar through the right angle clamp 47. Furthermore, the pressing member 6 is fixed by the locking block 45 during the pressing process and cannot move, thus achieving the fixing of the reinforcing bar by the fixed mounting plate 4.
[0035] The mounting slot 32 can fix the steel bars on one side of the movable mounting plate 3, and the angle and orientation of the clamps on the clamping part 5 can be adjusted arbitrarily, which can fix the intersection point formed by steel bars placed at any angle, further ensuring the stability of the steel bars.
[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
