Description

Technical Field

[0001] This invention belongs to the field of construction site measures and tools, specifically a portable temporary operating platform for tying column reinforcement bars. Background Technology

[0002] With continuous economic development and the growing acceptance of the paramount importance of life, people have placed higher demands on the safety and convenience of construction workers' operations on construction sites. Daily observations have revealed that during the process of tying column reinforcement bars on construction sites, construction workers often use readily available materials such as steel pipes, reinforcing bars, and angle irons, directly inserting them into the column reinforcement bars to form a temporary standing platform. These temporary platforms suffer from inconvenience and insufficient safety, seriously affecting workers' efficiency and safety.

[0003] Therefore, the present invention provides a portable temporary operation platform for tying column reinforcement bars. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a portable temporary operation platform for tying column reinforcement bars, comprising column reinforcement bars, column stirrups and platform mechanism, wherein multiple column reinforcement bars are provided and the column stirrups are used to fix the column reinforcement bars;

[0006] A standing platform, wherein the surface of the standing platform is provided with an opening and closing mechanism, the opening and closing mechanism can be a hinge or a hinge, and an upper pull rod and a lower support rod are movably connected to the surface of the standing platform through the opening and closing mechanism;

[0007] Two upper tie rods and two lower support rods are provided. The upper tie rod, the standing platform and the lower support rod are all fixedly connected with hooks. The upper tie rod and the lower support rod are connected to the column reinforcement and column stirrups by the hooks.

[0008] The surface of the hook is provided with a reinforcing mechanism, which is used to enhance the stability of the hook;

[0009] During operation, the upper pull rod and lower support rod are opened via the opening and closing mechanism, causing the hook to move closer to the column reinforcement and stirrups. The standing platform is then hung on the surface of the column reinforcement via the hook. The upper pull rod and lower support rod are then hung in the appropriate positions via the hook to form support. Through the cooperation of the upper pull rod and lower support rod, the force generated by the worker is reasonably transferred to the column reinforcement. Under the premise of ensuring worker safety, a suitable column reinforcement binding operation platform is provided, which can greatly improve the convenience and safety of column reinforcement binding for workers. It is applicable to column reinforcement binding in a wide range of construction sites.

[0010] Preferably, the reinforcing mechanism includes a telescopic ring, which is slidably connected within the hook by a spring. A shaft is slidably connected to the surface of the hook by a spring. A set of insertion holes is formed on the surface of the telescopic ring relative to the shaft. The cross-section of the telescopic ring is T-shaped. An arc-shaped plate is fixedly connected to the end of the sliding rod away from the connecting plate. The upper pull rod, lower support rod, and standing platform are all made of steel reinforcement. A sliding rod is slidably connected to the surface of the hook. Two sliding rods are provided, and the central axes of a pair of sliding rods and a hook are symmetrically distributed. A connecting plate is fixedly connected to the surface of a pair of sliding rods. A main magnetic block is fixedly connected to the surface of the connecting plate. A secondary magnetic block is fixedly connected to the end of the shaft near the main magnetic block.

[0011] During operation, when the hook is hung on the surface of the column reinforcement, the column reinforcement will squeeze the arc plate, causing the arc plate to slide the sliding rod away from the column reinforcement. At the same time, it will force the main magnetic block to move the auxiliary magnetic block, causing the auxiliary magnetic block to disengage the insertion shaft from the insertion hole. At this time, the telescopic ring is released from its restraint and pops out under the action of the spring. Meanwhile, when the insertion shaft slides to its limit position, the sliding rod continues to move, causing the main magnetic block and the auxiliary magnetic block to separate. Then, the spring causes the auxiliary magnetic block to engage in the next insertion hole, limiting the telescopic ring and preventing it from retracting. By using the hook in conjunction with the telescopic ring, the hook can form an almost complete circle, preventing it from disengaging and ensuring the stability of the hook connection. At the same time, the two sliding rods can improve the stability of the main magnetic block during sliding, preventing it from becoming uneven or stuck.

[0012] Preferably, the hook surface is connected to a threaded rod, and an extrusion plate is fixedly connected to the end of the threaded rod. The extrusion plate is arc-shaped, and a rubber pad is fixedly connected to the surface of the extrusion plate. During operation, after the hook is fixed to the surface of the column reinforcement, the threaded rod is turned to make the threaded rod drive the extrusion plate to come closer to the column reinforcement. This prevents the standing platform from shaking due to the different diameter of the column reinforcement, thereby improving the stability of the standing platform and expanding the applicability of this device.

[0013] Preferably, the upper pull rod and the lower support rod are both divided into a main rod and a secondary rod. The hooks are all fixedly installed at the end of the main rod. The surface of the main rod is provided with an installation groove. The end of the secondary rod is rotatably connected to a threaded rod II. The end of the threaded rod II away from the secondary rod is movably installed in the mounting through a thread. A nut is fixedly connected to the surface of the threaded rod.

[0014] During operation, when the installation distance of the column stirrups changes, in order to ensure the level of the standing platform, the nut is tightened, causing the nut to rotate the threaded rod. This allows the threaded rod to extend the main rod outward, thereby adjusting the installation positions of the lower support rod and the upper tie rod, ensuring that the standing platform remains level and further improving the safety of workers.

[0015] Preferably, a bearing is fixedly connected to the surface of the threaded rod two, and the threaded rod two is rotatably connected to the auxiliary rod through the bearing. A discharge port is opened on the surface of the main rod. A fixing ring is rotatably connected to the mounting groove through the thread. A rubber ring is fixedly connected to the surface of the fixing ring. A locking block is fixedly connected to the end of the threaded rod two, and a groove is opened on the surface of the fixing ring relative to the position of the locking block.

[0016] During operation, the bearing reduces the friction between the secondary rod and the threaded rod 2. When the threaded rod 2 is screwed into the mounting groove, it moves the fixing ring through the locking block. At the same time, the fixing ring moves the rubber ring, which cleans the threads in the mounting groove. This prevents impurities or debris generated by friction from remaining in the thread groove during the disassembly and assembly of the main rod and the secondary rod, which would affect the rotation of the threaded rod 2 and thus the extension and retraction of the main rod.

[0017] Preferably, the main rod has a cavity, and an elastic block is provided. The elastic block is made of hollow material. A push plate is fixedly connected to the surface of the elastic block. A fixed shaft is fixedly connected to the side of the push plate away from the elastic block. The end of the fixed shaft away from the elastic block slides through the side wall of the cavity. A telescopic rod is slidably connected to the inner surface of the fixed shaft by a spring. A top block is fixedly connected to the surface of the telescopic rod. The top block and the fixed ring are magnetically attracted to each other. An air hole is provided inside the telescopic rod. The telescopic rod, the fixed shaft, the push plate, and the elastic block are connected through the air hole. A limit block is slidably connected to the surface of the main rod by a spring. A limit groove is provided on the surface of the fixed shaft relative to the position of the limit block.

[0018] During operation, when the threaded rod two is in contact with the top block, the threaded rod two will squeeze the top block, causing the top block to move closer to the elastic block. At the same time, it will drive the telescopic rod to move and squeeze the spring to generate elastic force. When the telescopic rod retracts to its limit position, the top block continues to move, causing the limit block to disengage from the limit groove. At this time, the fixed shaft cavity retracts, and at the same time, it drives the push plate to squeeze the elastic block, causing the gas in the elastic block to be blown out through the air hole, and the impurities in the installation groove to be discharged through the discharge port. The limit block and the limit groove can play a role in storing force, making the gas blowing pressure greater and the cleaning efficiency higher. Then, when rotating the threaded rod two to move away from the elastic block, the magnetic attraction can help the elastic block drive the fixed shaft to return to its original position.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The portable temporary operating platform for tying column rebar described in this invention transfers the worker's weight to the column rebar in a reasonable manner through the upper pull rod and the lower support rod. Under the premise of ensuring worker safety, it provides a suitable operating platform for tying column rebar, which can greatly improve the convenience and safety of workers in tying column rebar.

[0021] 2. The portable temporary operating platform for tying column rebar described in this invention, through the combination of hooks and telescopic rings, allows the hooks to form an approximately complete circle, preventing detachment and ensuring the stability of the hook tying. At the same time, the two sliding rods can improve the stability of the main magnetic block during sliding, preventing unevenness or jamming. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1:

[0032] like Figures 1 to 3As shown in the figure, a portable temporary operation platform for tying column reinforcement bars according to an embodiment of the present invention includes column reinforcement bars 1, column stirrups 2 and platform mechanism. Multiple column reinforcement bars 1 are provided, and the column stirrups 2 are used to fix the column reinforcement bars 1.

[0033] A standing platform 5 is provided with an opening and closing mechanism 7 on its surface. The opening and closing mechanism 7 can be a hinge or a hinge. An upper pull rod 4 and a lower support rod 3 are movably connected to the surface of the standing platform 5 through the opening and closing mechanism 7.

[0034] Two upper pull rods 4 and two lower support rods 3 are provided. Hooks 6 are fixedly connected to the surfaces of the upper pull rods 4, the standing platform 5 and the lower support rods 3. The upper pull rods 4 and the lower support rods 3 are connected to the surfaces of the column reinforcement 1 and the column stirrups 2 through the hooks 6.

[0035] The surface of the hook 6 is provided with a reinforcing mechanism, which is used to enhance the stability of the hook 6;

[0036] During operation, the upper pull rod 4 and lower support rod 3 are opened via the opening and closing mechanism 7, causing the hook 6 to move closer to the column reinforcement 1 and column stirrup 2. The standing platform 5 is then hung on the surface of the column reinforcement 1 via the hook 6. The upper pull rod 4 and lower support rod 3 are then hung in appropriate positions via the hook 6 to form a support. Through the cooperation of the upper pull rod 4 and lower support rod 3, the force generated by the worker is reasonably transferred to the column reinforcement 1. Under the premise of ensuring worker safety, a suitable column reinforcement 1 binding operation platform is provided, which can greatly improve the convenience and safety of workers binding column reinforcement 1. It is applicable to the field of column reinforcement 1 binding in a wide range of construction sites.

[0037] The reinforcing mechanism includes a telescopic ring 11, which is slidably connected within the hook 6 by a spring. A shaft 17 is slidably connected to the surface of the hook 6 by a spring. A set of insertion holes are provided on the surface of the telescopic ring 11 relative to the shaft 17. The cross-section of the telescopic ring 11 is "T" shaped. An arc-shaped plate is fixedly connected to the end of the slide rod 10 away from the connecting plate 14. The upper pull rod 4, the lower support rod 3, and the standing platform 5 are all made of steel bars. The slide rod 10 is slidably connected to the surface of the hook 6. There are two slide rods 10. The pair of slide rods 10 are symmetrically distributed around the central axis of the hook 6. A connecting plate 14 is fixedly connected to the surface of the pair of slide rods 10. A main magnetic block 15 is fixedly connected to the surface of the connecting plate 14. A secondary magnetic block 16 is fixedly connected to the end of the shaft 17 near the main magnetic block 15.

[0038] During operation, when the hook 6 is hung on the surface of the column reinforcement 1, the column reinforcement 1 will squeeze the arc plate, causing the arc plate to slide the slide rod 10 away from the column reinforcement 1. At the same time, it will force the main magnetic block 15 to move the auxiliary magnetic block 16, causing the auxiliary magnetic block 16 to move the insertion shaft 17 away from the insertion hole. At this time, the telescopic ring 11 is released from its restriction and pops out under the action of the spring. Meanwhile, when the insertion shaft 17 slides to its limit position, the slide rod 10 continues to move, causing the main magnetic block 15 and the auxiliary magnetic block 16 to separate. At this time, the spring causes the auxiliary magnetic block 16 to be inserted into the next insertion hole, limiting the telescopic ring 11 and preventing the telescopic ring 11 from retracting. By using the hook 6 in conjunction with the telescopic ring 11, the hook 6 can form an approximately complete circle, thereby ensuring the stability of the hook 6 connection. The two slide rods 10 can improve the stability of the main magnetic block 15 when sliding, preventing it from becoming uneven or stuck.

[0039] The hook 6 is connected to a threaded rod 13 via a threaded connection. An extrusion plate 12 is fixedly connected to the end of the threaded rod 13. The extrusion plate 12 is arc-shaped and has a rubber pad fixedly connected to its surface. During operation, after the hook 6 is fixed to the surface of the column reinforcement 1, the threaded rod 13 is turned to make the threaded rod drive the extrusion plate 12 to come closer to the column reinforcement 1. This prevents the hook 6 from shaking due to the different diameter of the column reinforcement 1, thereby improving the stability of the standing platform 5 and expanding the applicability of this device.

[0040] Example 2:

[0041] like Figures 4 to 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the upper pull rod 4 and the lower support rod 3 are both divided into a main rod 8 and a secondary rod 9. The hooks 6 are all fixedly installed at the end of the main rod 8. The surface of the main rod 8 is provided with an installation groove 20. The end of the secondary rod 9 is rotatably connected to a threaded rod 22. The end of the threaded rod 22 away from the secondary rod 9 is movably installed in the mounting through a thread. The surface of the threaded rod is fixedly connected with a nut 23.

[0042] During operation, when the installation distance of the column stirrups 2 changes, in order to ensure the level of the standing platform 5, the nut 23 is tightened, causing the threaded rod 22 to rotate. This allows the threaded rod 22 to extend the main rod 8 outward, thereby adjusting the installation positions of the lower support rod 3 and the upper tie rod 4, ensuring that the standing platform 5 remains level and further improving the safety of workers.

[0043] The threaded rod 22 is fixedly connected to a bearing 31, and the threaded rod 22 is rotatably connected to the auxiliary rod 9 via the bearing 31. The main rod 8 has a discharge port 25 on its surface. The mounting groove 20 is rotatably connected to a fixing ring 21 via a thread. A rubber ring is fixedly connected to the surface of the fixing ring 21. A locking block 24 is fixedly connected to the end of the threaded rod 22. The fixing ring 21 has a slot on its surface relative to the locking block 24.

[0044] During operation, the bearing 31 reduces the friction between the secondary rod 9 and the threaded rod 22. When the threaded rod 22 is screwed into the mounting groove 20, it will drive the fixing ring 21 to move through the locking block 24. At the same time, the fixing ring 21 drives the rubber ring to move, which cleans the threads in the mounting groove 20. This prevents impurities or debris generated by friction from remaining in the thread groove during the disassembly and assembly of the main rod 8 and the secondary rod 9, which would affect the rotation of the threaded rod 22 and thus the extension and retraction of the main rod 8.

[0045] The main rod 8 has a cavity and an elastic block 18 is provided. The elastic block 18 is made of hollow material. A push plate 19 is fixedly connected to the surface of the elastic block 18. A fixed shaft 27 is fixedly connected to the side of the push plate 19 away from the elastic block 18. The end of the fixed shaft 27 away from the elastic block 18 slides through the side wall of the cavity. A telescopic rod 29 is slidably connected to the inner surface of the fixed shaft 27 by a spring. A top block 30 is fixedly connected to the surface of the telescopic rod 29. The top block 30 and the fixed ring 21 are magnetically attracted to each other. An air hole 28 is provided in the telescopic rod 29. The telescopic rod 29, the fixed shaft 27, the push plate 19 and the elastic block 18 are connected through the air hole 28. A limit block 26 is slidably connected to the surface of the main rod 8 by a spring. A limit groove is provided on the surface of the fixed shaft 27 relative to the position of the limit block 26.

[0046] During operation, when the threaded rod 22 is in contact with the top block 30, the threaded rod 22 will squeeze the top block 30, causing the top block 30 to move closer to the elastic block 18. At the same time, it will drive the telescopic rod 29 to move and squeeze the spring to generate elastic force. When the telescopic rod 29 retracts to its limit position, the top block 30 continues to move, causing the limit block 26 to disengage from the limit groove. At this time, the fixed shaft 27 retracts into the cavity, and at the same time, it drives the push plate 19 to squeeze the elastic block 18, causing the gas in the elastic block 18 to be blown out through the air hole 28, and the impurities in the mounting groove 20 to be discharged through the discharge port 25. The limit block 26 and the limit groove can play a role in storing force, making the gas blowing pressure greater and the cleaning efficiency higher. Then, when the threaded rod 22 is rotated to move away from the elastic block 18, the magnetic attraction can help the elastic block 18 drive the fixed shaft 27 to reset.
