Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and particularly relates to a high-precision portable positioning device for the upper part of the structural column steel bars. Background Art

[0002] A structural column refers to a reinforced concrete structural column that should be set in the walls of a multi-story brick-concrete structure building to enhance the integrity and stability of the building. It is connected to the ring beams of each floor to form a spatial frame that can resist bending and shear forces. It is an effective measure to prevent the collapse of the house. The setting positions of the structural columns are at the four corners of the exterior wall, the intersection of the transverse wall and the exterior longitudinal wall at the staggered floor part, both sides of the larger openings, the intersection of the interior and exterior walls of the large rooms, etc. The structural column mainly does not bear the vertical load, but resists the shear force, seismic and other horizontal loads. The reinforced concrete structural column plays an important role in the earthquake resistance of multi-story masonry houses. The structural column is integrally poured with the ring beam, ground beam, and foundation beam to form a spatial skeleton, so as to improve the overall stiffness and ductility of the building, restrain the development of wall cracks, thereby increasing the stability of the building and enhancing the earthquake resistance ability of the building. And the accurate positioning of the upper part of the structural column steel bars is the core link to ensure the bearing capacity and structural stability of the structural column.

[0003] The current positioning devices for the upper part of the structural column steel bars are found to have at least the following technical problems:

[0004] First, on the one hand, the traditional steel bar positioning relies on manual operation based on experience. Not only is it difficult to guarantee the positioning accuracy, but the results of different construction workers vary greatly, which is likely to cause the steel bar position to deviate, seriously affecting the mechanical properties of the building structure.

[0005] Second, on the other hand, the traditional positioning method has complicated procedures and requires multiple measurements, adjustments and fixations. It not only consumes a large amount of manpower and material resources, but also greatly reduces the construction efficiency and slows down the project progress.

[0006] Third, in addition, during the construction process, due to the vibration generated during concrete pouring, the traditional positioning device is difficult to ensure that the steel bars are always in the accurate position and are prone to displacement, thus bringing potential safety hazards to the building structure.

[0007] In view of the above problems, we propose a high-precision portable positioning device for the upper part of the structural column steel bars. Summary of the Invention

On both sides of the two abutting rods, there are push rods. On both side surfaces of the positioning plate, there is a set of arc-shaped grooves I. On the opposite sides of the two abutting rods, there is a set of arc-shaped grooves II. On the positioning plate, there is a fastening assembly. The fastening assembly includes two groups of clamping rods. On the surface of each clamping rod, there is an arc-shaped groove III. At the bottom end of each clamping rod, there is a sliding block fixedly connected. Between the two groups of clamping rods, there is a two-way threaded rod I passing through in a threaded manner. The rotation of the two-way threaded rod I controls the relative movement of every two clamping rods. Four round rods pass through each push rod movably. Each round rod is fixedly installed on the positioning plate. On each round rod, there is a spring sleeved movably. Each push rod is fixedly connected to the abutting rod through four springs respectively. Inside the positioning plate, there is a two-way threaded rod II rotatably installed. The two-way threaded rod II passes through the two push rods and is threadedly connected to the two push rods. The two-way threaded rod II passes through the two abutting rods movably.

[0013] Preferably: Each clamping rod is arranged along the width direction of the positioning plate, and each abutting rod is arranged along the length direction of the positioning plate.

[0014] Preferably: The two-way threaded rod I is rotatably installed on the positioning plate. At both ends of the two-way threaded rod I, there are a gear I and a handwheel fixedly connected respectively.

[0015] Preferably: On the upper surface of the positioning plate, there are four sliding grooves. Each sliding block is slidably installed in the sliding groove respectively. At the bottom end of the positioning plate, there is a limiting rod fixedly installed. The limiting rod passes through the four sliding blocks movably to limit and support the sliding blocks.

[0016] Preferably: At the end of each round rod, there is a limiting block fixedly connected. Each limiting block is located at the outer end of the push rod.

[0017] Preferably: On the two-way threaded rod II, there is a bevel gear I fixedly installed. Inside the positioning plate, there is a rotating shaft rotatably installed. On the rotating shaft, there is a bevel gear II fixedly installed. The bevel gear I meshes with the bevel gear II.

[0021] Beneficial effects

[0022] First: High positioning accuracy: Through the positioning plate, the abutting rod and the arc-shaped grooves specially designed on the clamping rod, the steel bars are clamped in multiple directions, effectively restricting the displacement of the steel bars in all directions, significantly improving the positioning accuracy. At the same time, the mechanical transmission system prompts the components to move synchronously, ensuring the consistency when positioning multiple steel bars, and laying a solid foundation for subsequent construction.

[0023] Second: Simple and fast operation: Only by rotating the handwheel, the positioning and fastening operations of the steel bars can be completed through the linkage of a series of mechanical structures, without complex operation processes, greatly shortening the construction time, improving the construction efficiency, and the position adjustment of the device at the top of the structural column only requires sliding the fixing plate and tightening the bolts, which is simple to operate.

[0024] Third: Strong structural stability: The spring design between the push rod and the abutting rod, while avoiding movement interference, continuously applies a stable clamping force to the steel bars, reducing the risk of displacement of the steel bars during construction. In addition, the stable locking structure between the fixing plate and the base ensures that the device will not displace during subsequent construction, guaranteeing the stability of the entire construction process.

[0025] Fourth: Good adaptability and flexibility: The sliding connection design between the fixing plate and the base, combined with the equidistantly distributed threaded holes on the surface of the base, can flexibly adjust the position of the device according to different construction requirements, effectively improving the adaptability of the device to different construction scenarios and expanding its application range.

[0037] Embodiment: As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown in the figure, in view of the problems existing in the prior art, the present invention provides a high-precision portable positioning device for the upper steel bars of construction columns, which includes a positioning plate 1. Both sides of the positioning plate 1 are provided with abutting rods 2. Both sides of the two abutting rods 2 are provided with push rods 4. A set of arc grooves one 11 are opened on both side surfaces of the positioning plate 1. A set of arc grooves two 21 are opened on the opposite sides of the two abutting rods 2. A fastening assembly 3 is arranged on the positioning plate 1. The fastening assembly 3 includes two groups of clamping rods 31. An arc groove three 32 is opened on the surface of each clamping rod 31. The bottom end of each clamping rod 31 is fixedly connected with a slider 33. A two-way threaded rod one 34 is threadedly connected through between the two groups of clamping rods 31. The two-way threaded rod one 34 rotates to control the relative movement of every two clamping rods 31. Four round rods 41 are movably penetrated through each push rod 4. Each round rod 41 is fixedly installed on the positioning plate 1. A spring 42 is movably sleeved on each round rod 41. Each push rod 4 is fixedly connected with the abutting rod 2 through four springs 42 respectively. A two-way threaded rod two 5 is rotatably installed in the positioning plate 1. The two-way threaded rod two 5 penetrates through the two push rods 4 and is threadedly connected with the two push rods 4. The two-way threaded rod two 5 movably penetrates through the two abutting rods 2. Each clamping rod 31 is arranged along the width direction of the positioning plate 1. Each abutting rod 2 is arranged along the length direction of the positioning plate 1. The two-way threaded rod one 34 is rotatably installed on the positioning plate 1. Two ends of the two-way threaded rod one 34 are respectively fixedly connected with a gear one 35 and a hand wheel 36. Four chute 12 are opened on the upper surface of the positioning plate 1. Each slider 33 is respectively slidably installed in the chute 12. A limiting rod 13 is fixedly installed at the bottom end of the positioning plate 1. The limiting rod 13 movably penetrates through the four sliders 33 to limit and support the sliders 33. A limiting block 43 is fixedly connected to the end of each round rod 41. Each limiting block 43 is located at the outer end of the push rod 4. A bevel gear one 52 is fixedly installed on the two-way threaded rod two 5. A rotating shaft 51 is rotatably installed in the positioning plate 1. A bevel gear two 53 is fixedly installed on the rotating shaft 51. The bevel gear one 52 is meshed with the bevel gear two 53. A gear two 54 is fixedly installed on the rotating shaft 51. A toothed synchronous belt 37 is sleeved on the gear one 35 and the gear two 54. A fixing plate 7 is fixedly installed at the bottom end of the positioning plate 1. A bolt 72 is screwed into the fixing plate 7. A base 6 is arranged at the bottom of the fixing plate 7. A dovetail groove 61 is opened in the middle of the upper surface of the base 6. A dovetail slide bar 71 is fixedly installed in the middle of the bottom end of the fixing plate 7. The dovetail slide bar 71 is slidably installed in the dovetail groove 61. A plurality of threaded holes 62 adapted to the bolt 72 are equidistantly opened on the surface of the base 6. The threaded holes 62 are arranged along the length direction of the base 6;

[0038] When carrying out the positioning operation of the upper steel bars of the structural column, first place the positioning device stably on the top of the structural column. Subsequently, pass the four steel bars to be positioned through the corresponding four arc-shaped grooves 11 on the positioning plate 1 respectively. After the steel bars are inserted, turn the handwheel 36 clockwise. The rotation of the handwheel 36 will drive the synchronous rotation of the double-threaded rod 34 fixedly connected to it. During the rotation of the double-threaded rod 34, the gear 35 fixed at its end rotates accordingly. The gear 35 is in transmission connection with the gear 54 through the toothed synchronous belt 37, thereby driving the rotation of the gear 54. The rotation of the gear 54 drives the synchronous rotation of the rotating shaft 51. The bevel gear 53 fixed on the rotating shaft 51 rotates accordingly. Through the meshing action of the bevel gear 53 and the bevel gear 52, the bevel gear 52 is driven to rotate. Since the bevel gear 52 is fixed on the double-threaded rod 5, the double-threaded rod 5 also starts to rotate. The rotation of the double-threaded rod 5 drives the two push rods 4 threadedly connected to it to move closer to each other along the round rod 41. Since the push rod 4 and the abutting rod 2 are fixedly connected by four springs 42, and the abutting rod 2 is not blocked in the initial state, during the process of the push rods 4 moving closer to each other, the two abutting rods 2 are driven to move closer to each other by the pulling force of the springs 42. As the abutting rods 2 approach, the four steel bars are respectively clamped between each arc-shaped groove 11 and each arc-shaped groove 21, thus realizing the preliminary positioning of the steel bars;

[0039] During the preliminary positioning process, the rotation of the double-threaded rod 34 not only drives the actions of the push rod 4 and the abutting rod 2, but also drives the two clamping rods 31 threadedly connected to it to move closer to each other. When the steel bar contacts the inner walls of the arc-shaped groove 21 and the arc-shaped groove 11, at this time, the arc-shaped groove 32 at the two clamping rods 31 has not yet been in close contact with the surface of the steel bar. To realize the fastening of the steel bar, it is necessary to continue to turn the handwheel 36 clockwise, driving the further rotation of the double-threaded rod 34, so that the two clamping rods 31 continue to move closer to each other. As the clamping rods 31 move, the steel bar is gradually clamped between the two arc-shaped grooves 32. By using the close fit between the arc-shaped groove 32 and the surface of the steel bar, the fastening of the steel bar is realized, ensuring that the steel bar remains stable in the positioning device;

[0040] After the preliminary positioning and fastening of the steel bar are completed, if the handwheel 36 is rotated clockwise continuously, the double-threaded rod 34 will continue to rotate, and then the two push rods 4 will continue to move closer to each other. Since the steel bar is already in close contact with the inner wall of the arc-shaped groove 21 at this time, the movement of the abutting rod 2 is restricted. As the push rod 4 continues to move, the spring 42 between the push rod 4 and the abutting rod 2 is compressed. The spring 42 generates elastic deformation and stores elastic potential energy. In this process, even if the abutting rod 2 cannot move further, the push rod 4 can still continue to move relying on the compression of the spring 42, avoiding the occurrence of movement interference. At the same time, the elastic force generated by the compression of the spring 42 will continuously apply pressure to the abutting rod 2, further enhancing the clamping force on the steel bar and ensuring the stability of the steel bar positioning.

[0041] When the positioning and fastening of the steel bar are completed, if it is necessary to adjust the position of the positioning device at the top of the structural column, the sliding connection structure between the fixing plate 7 and the base 6 can be used. The dovetail slide bar 71 fixedly installed at the bottom of the fixing plate 7 is slidably installed in the dovetail groove 61 opened on the upper surface of the base 6. This enables the fixing plate 7 and the positioning plate 1 to slide along the length direction of the base 6. After adjusting to the appropriate position, the bolt 72 is rotated and screwed into the corresponding threaded hole 62 through the equally spaced threaded holes 62 opened on the surface of the base 6. The tightening of the bolt 72 will firmly fix the fixing plate 7 and the base 6, thereby locking the adjusted position of the fixing plate 7 and the positioning plate 1 and ensuring that the positioning device will not be displaced during the subsequent construction process, providing a reliable guarantee for the positioning of the upper steel bar of the structural column.

[0042] Working principle:

[0043] First step, when carrying out the positioning operation of the upper steel bars of the structural column, first place the positioning device stably on the top of the structural column. Subsequently, pass the four steel bars to be positioned through the corresponding four arc-shaped grooves 11 on the positioning plate 1 respectively. After the steel bars are inserted, turn the handwheel 36 clockwise. The rotation of the handwheel 36 will drive the two-way threaded rod 1 34 fixedly connected to it to rotate synchronously. During the rotation of the two-way threaded rod 1 34, the gear 1 35 fixed at its end rotates accordingly. The gear 1 35 is in transmission connection with the gear 2 54 through the toothed synchronous belt 37, thereby driving the gear 2 54 to rotate. The rotation of the gear 2 54 drives the rotating shaft 51 to rotate synchronously. The conical gear 2 53 fixed on the rotating shaft 51 rotates accordingly. Through the meshing action of the conical gear 2 53 and the conical gear 1 52, the conical gear 1 52 is driven to rotate. Since the conical gear 1 52 is fixed on the two-way threaded rod 2 5, the two-way threaded rod 2 5 also starts to rotate. The rotation of the two-way threaded rod 2 5 drives the two push rods 4 threaded with it to move closer to each other along the round rod 41. Since the push rod 4 and the abutting rod 2 are fixedly connected by four springs 42, and the abutting rod 2 is not blocked in the initial state, during the process of the push rods 4 moving closer to each other, the two abutting rods 2 are driven to move closer to each other by the pulling force of the springs 42. As the abutting rods 2 approach, the four steel bars are respectively clamped between each arc-shaped groove 11 and each arc-shaped groove 21, thus realizing the preliminary positioning of the steel bars;

[0044] Second step, during the preliminary positioning in the first step, the rotation of the two-way threaded rod 1 34 not only drives the push rod 4 and the abutting rod 2 to act, but also drives every two clamping rods 31 threaded with it to move closer to each other. When the steel bar contacts the inner walls of the arc-shaped groove 21 and the arc-shaped groove 11, at this time, the arc-shaped groove 32 at the two clamping rods 31 has not yet been in contact with the surface of the steel bar. To tighten the steel bar, it is necessary to continue to turn the handwheel 36 clockwise, driving the two-way threaded rod 1 34 to rotate further, so that every two clamping rods 31 continue to move closer to each other. As the clamping rods 31 move, the steel bar is gradually clamped between the two arc-shaped grooves 32. By using the close fit between the arc-shaped groove 32 and the surface of the steel bar, the steel bar is tightened to ensure that the steel bar remains stable in the positioning device;

[0045] In the third step, after the preliminary positioning and fastening of the steel bars are completed, if the handwheel 36 is continuously rotated clockwise, the double-threaded rod 34 will continue to rotate, and then the two push rods 4 will continue to move closer to each other. Since the steel bars are already in close contact with the inner wall of the second arc-shaped groove 21 at this time, the movement of the abutting rod 2 is restricted. As the push rod 4 continues to move, the spring 42 between the push rod 4 and the abutting rod 2 is compressed. The spring 42 undergoes elastic deformation and stores elastic potential energy. In this process, even if the abutting rod 2 cannot continue to move, the push rod 4 can still continue to move relying on the compression of the spring 42, avoiding the occurrence of movement interference. At the same time, the elastic force generated by the compression of the spring 42 will continuously apply pressure to the abutting rod 2, further enhancing the clamping force on the steel bars and ensuring the stability of the steel bar positioning.

[0046] In the fourth step, when the positioning and fastening of the steel bars are completed, if it is necessary to adjust the position of the positioning device at the top of the structural column, the sliding connection structure between the fixing plate 7 and the base 6 can be utilized. The dovetail slide bar 71 fixedly installed at the bottom of the fixing plate 7 is slidably installed in the dovetail groove 61 opened on the upper surface of the base 6. This enables the fixing plate 7 and the positioning plate 1 to slide along the length direction of the base 6. After adjusting to the appropriate position, the bolt 72 is rotated and screwed into the corresponding threaded hole 62 through the equally spaced threaded holes 62 opened on the surface of the base 6. The tightening of the bolt 72 will firmly fix the fixing plate 7 and the base 6, thereby locking the adjusted positions of the fixing plate 7 and the positioning plate 1 and ensuring that the positioning device will not be displaced during subsequent construction, providing a reliable guarantee for the positioning of the upper steel bars of the structural column.

[0047] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
