Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a building steel bar positioning structure and a construction method thereof. Background Art

[0002] Rebar is an important component of building structures. During construction, multiple rebars are usually welded or tied together to form a steel cage. In construction, the steel cage mainly plays a tensile role. Because concrete has high compressive strength but low tensile strength, the steel cage constrains the pile concrete, allowing it to withstand a certain amount of axial tension and horizontal force, thereby improving the bearing capacity of the concrete structure.

[0003] During the production, transportation and storage process, steel bars will inevitably be contaminated with various impurities. If these impurities are not cleaned up, they will seriously affect the bonding strength between the steel bars and other materials, thereby reducing the overall engineering quality of the building. At the same time, during the production, transportation and storage process, steel bars are prone to bending and deformation, which brings difficulties to subsequent positioning welding work.

[0022] The present invention also provides a construction method of a building steel bar positioning structure, the method comprising the following steps:

[0023] S1. Rebar pretreatment: First, insert the rebar into the spray assembly through the auxiliary support plate, and at the same time start the water pump in the liquid storage tank to spray the cleaning liquid in the liquid storage tank through the main water pipe and the delivery pipe onto the rebar located in the connecting tube;

[0024] S2, steel bar straightening: The steel bar sprayed with cleaning liquid passes through the connecting tube and enters between the two sets of straightening rollers. At this time, the drive motor starts, driving the two sets of straightening rollers to rotate, and the steel bar is straightened under the squeezing of the two sets of straightening rollers;

[0025] S3, steel bar cleaning: After being straightened by the straightening roller, the steel bar enters between the first brush plate and the second brush plate. At this time, the straightening roller continues to rotate, and the straightening roller drives multiple connecting plates to rotate at the same time, so that the synchronous push rod drives multiple synchronous frames to move left and right. The multiple synchronous frames drive the first brush plate and the second brush plate to move left and right through the connecting rod, and brush the steel bar between the first brush plate and the second brush plate;

[0026] S4. Steel bar positioning: The steel bar after brushing is moved out from the first brush plate and the second brush plate under the push of the straightening roller, and passes through the positioning hole on the water suction wheel. When the steel bar passes through the water suction wheel, the cleaning liquid remaining on the steel bar will be absorbed by the water suction wheel. The steel bar passing through the positioning hole on the water suction wheel continues to move until it passes through the positioning hole on the positioning gear plate. When the steel bar touches the induction switch on the second connecting seat, the induction switch sends a signal to start the third servo motor, and the third servo motor drives the driving gear to rotate. The positioning gear plate rotates synchronously under the drive of the driving gear, causing the water suction wheel and the positioning gear plate to rotate, so that the next positioning hole is rotated to the level of the first brush plate, and then other steel bars are inserted and the above work is repeated.

[0027] Technical effects and advantages of the present invention:

[0028] In the present invention, after the steel bar enters the spray assembly, the cleaning liquid can be sprayed on the surface of the steel bar. Subsequently, the steel bar enters between the first brush plate and the second brush plate. Driven by the rotation of the straightening roller, the connecting plate, the synchronous push rod, the synchronous frame and the connecting rod work together to enable the first brush plate and the second brush plate to brush the steel bar. With the help of the cleaning liquid, the oil or dust on the steel bar can be effectively removed. The sewage after brushing is discharged in time through the drain pipe, ensuring that the surface of the steel bar is clean, providing a good foundation for subsequent processing and use, and avoiding the impact of impurities on the bonding strength of the steel bar and other materials and the overall project quality.

[0029] In the present invention, the driving motor drives the second synchronous shaft and the straightening roller to rotate through the first synchronous shaft and the driving belt. The two straightening rollers rotate simultaneously under the action of the synchronous gear to squeeze and straighten the steel bars. This design ensures the uniform distribution of the straightening force, can effectively eliminate the bending deformation of the steel bars, improve the straightness of the steel bars, facilitate subsequent positioning welding work, and ensure that the steel bars exert their due mechanical properties in the concrete structure, thereby enhancing the stability and safety of the building.

[0030] At the same time, the multiple groups of extrusion grooves arranged on the straightening roller can select appropriate extrusion grooves according to the actual diameter of the steel bar to ensure the straightening effect. At the same time, by starting the first servo motor to drive the first transmission screw to rotate, the fixed frame moves on the support seat, which can allow different extrusion grooves on the straightening roller to be connected with the positioning holes on the suction wheel, further adapting to the use of steel bars of different diameters, facilitating the production of steel cages of different diameters, without the need for frequent replacement of equipment or components, and reducing construction costs and time costs.

[0045] Specifically, when making a steel cage, first, the steel bar is passed through the spray assembly 3 and inserted into the straightening assembly 2, and the straightening assembly 2 is started. The steel bar is straightened by the straightening assembly 2 to facilitate subsequent welding or bundling work. When the steel bar passes through the spray assembly 3, the spray assembly 3 simultaneously sprays cleaning liquid on the steel bar. After the steel bar is straightened by the straightening assembly 2, it enters the cleaning assembly 4 under the push of the straightening assembly 2. When the straightening assembly 2 is started, the cleaning assembly 4 is also driven to start, and the steel bar is brushed by the cleaning assembly 4 to brush off the dust, oil and other stains on the surface of the steel bar. The treated steel bar is passed between the first positioning assembly 5 and the second positioning assembly 6. After one steel bar is passed through, the second positioning assembly 6 drives the first positioning assembly 5 to rotate, and the above work is repeated until a sufficient amount of steel bars are passed through. After the passing through is completed, the reinforcing bar is wrapped around the outside of the steel bar and the reinforcing bar is welded to the steel bar to complete the production of the steel cage.

[0046] In this embodiment, the first positioning component 5 includes a first support frame 51, the top of the first support frame 51 is fixedly connected to a first connecting seat 52, the first connecting seat 52 is rotatably connected to a water suction wheel 53, and the water suction wheel 53 is filled with a water-absorbing sponge, and two sets of auxiliary wheels 54 are also provided in the first connecting seat 52, and the two sets of auxiliary wheels 54 are in contact with the side walls of the water suction wheel 53. The second positioning component 6 includes a second support frame 61, the top of the second support frame 61 is fixedly connected to a second connecting seat 62, the second connecting seat 62 is rotatably connected to a positioning gear plate 63, and a synchronization rod 64 is also threadedly connected to the positioning gear plate 63, and the other end of the synchronization rod 64 passes through the water suction wheel 53 and extends to the other side of the water suction wheel 53, and a fixing sleeve 55 is threadedly connected to the extended end of the synchronization rod 64, and a third servo motor 65 is also fixedly connected to one side of the second connecting seat 62, and the output end of the third servo motor 65 is fixedly connected to a driving gear 66. The movable gear 66 is rotatably connected to the second connecting seat 62, and the driving gear 66 is meshed with the positioning gear plate 63. The water suction wheel 53 and the positioning gear plate 63 are provided with multiple groups of one-to-one corresponding positioning holes. Two groups of second auxiliary grooves 15 and a group of second limiting grooves 16 are provided at one end of the top of the support seat 1 near the second support frame 61. The second transmission screw 17 is rotatably connected in the second limiting groove 16. A second servo motor 18 is fixedly connected to the side wall of the support seat 1. The output end of the second servo motor 18 is fixed to one end of the second transmission screw 17. The bottom of the second support frame 61 is also fixedly connected to multiple groups of sliding seats 67. The multiple groups of sliding seats 67 are respectively slidably connected to the two groups of second auxiliary grooves 15 and the second limiting groove 16, and the sliding seats 67 located in the second limiting groove 16 are threadedly connected to the second transmission screw 17. A plurality of induction switches 68 are also fixedly connected to one side of the second connecting seat 62 near the positioning gear plate 63;

[0047] Specifically, when making a steel cage, the treated steel bar passes through the positioning hole on the water suction wheel 53. When the steel bar passes through the water suction wheel 53, the cleaning liquid remaining on the steel bar will be absorbed by the water suction wheel 53. The steel bar passing through the positioning hole on the water suction wheel 53 continues to move until it passes through the positioning hole on the positioning gear plate 63. When the steel bar touches the induction switch 68 on the second connecting seat 62, the induction switch 68 sends a signal to start the third servo motor 65, and the third servo motor 65 drives the driving gear 66 to rotate. The positioning gear plate 63 rotates synchronously under the drive of the driving gear 66, so that the water suction wheel 53 and the positioning gear plate 63 rotate, and the next positioning hole rotates to be level with the first brush plate 45. Then other steel bars are inserted and the above work is repeated.

[0048] When the steel cage is completed, the fixing sleeve 55 is removed with a tool, the fixing of the synchronization rod 64 and the water suction wheel 53 is released, and the second servo motor 18 is started. The second servo motor 18 drives the second transmission screw 17 to rotate, and the second transmission screw 17 drives the second support frame 61 and the second connecting seat 62 to slide through the sliding seat 67, so that the second connecting seat 62 drives the positioning gear plate 63 to move in a direction away from the first positioning assembly 5. The positioning gear plate 63 simultaneously drives the synchronization rod 64 to be pulled out of the water suction wheel 53;

[0049] When the sliding seat 67 moves to the end of the second limiting groove 16, the second servo motor 18 is turned off, and the synchronization rod 64 is rotated to remove the synchronization rod 64 from the positioning gear plate 63. Then, a lifting device (such as a crane) is used to lift the steel cage out of the positioning gear plate 63.

[0050] By setting multiple groups of positioning holes on the suction wheel 53 and the positioning gear plate 63, when in use, appropriate positioning holes can be selected for insertion according to actual construction needs, thereby making steel cages of different diameters, which is convenient for use;

[0051] In this embodiment, the straightening assembly 2 includes a fixed frame 21, which is slidably connected to the top of the support seat 1, and two groups of straightening rollers 22 are rotatably connected to the fixed frame 21. Both groups of straightening rollers 22 are provided with multiple groups of extrusion grooves of different widths. The bottom of the fixed frame 21 is also fixedly connected to a drive motor 23, and the output end of the drive motor 23 is fixedly connected to a first synchronous shaft 24, one group of straightening rollers 22 is fixedly connected to a second synchronous shaft 25, and a driving belt 26 is provided between the first synchronous shaft 24 and the second synchronous shaft 25. The first synchronous shaft 24 and the second synchronous shaft 25 are connected by the driving belt 26. The two straightening rollers 22 are fixedly connected to a synchronous gear 27 on one side away from the second synchronous shaft 25, and the two synchronous gears 27 are meshed with each other. The fixed frame 21 is away from one side of the first positioning assembly 5. An auxiliary support plate 28 is also fixedly connected to the side, and a placement groove adapted to multiple groups of extrusion grooves is provided on the top of the auxiliary support plate 28. The spray assembly 3 is located between the straightening roller 22 and the auxiliary support plate 28. A water receiving tray 29 is also fixedly connected to the fixed frame 21. The water receiving tray 29 is located between the straightening roller 22 and the drive motor 23. The top of the support base 1 is also provided with a first auxiliary groove 11 and a first limiting groove 12 for sliding of the fixed frame 21. The first limiting groove 12 is rotatably connected to the first transmission screw 13. The bottom of the fixed frame 21 is fixedly connected to multiple groups of sliding blocks. The sliding blocks located in the first limiting groove 12 are threadedly connected to the first transmission screw 13. A first servo motor 14 is also fixedly connected to one side of the support base 1. The output end of the first servo motor 14 is fixed to one end of the first transmission screw 13;

[0052] Specifically, when in use, when the steel bar moves from the spray assembly 3 to between the two straightening rollers 22, the drive motor 23 is started, and the drive motor 23 drives the second synchronous shaft 25 and the straightening roller 22 to rotate through the first synchronous shaft 24 and the drive belt 26. The two straightening rollers 22 rotate simultaneously under the action of the synchronous gear 27, squeezing the passing steel bar and straightening the steel bar;

[0053] By setting multiple groups of extrusion grooves on the straightening roller 22, the appropriate extrusion groove can be selected according to the actual diameter of the steel bar during use to ensure the straightening effect;

[0054] At the same time, when in use, by starting the first servo motor 14, the first transmission screw 13 can be driven to rotate, so that the first transmission screw 13 drives the fixing frame 21 to move on the support base 1, so that the different extrusion grooves on the straightening roller 22 can be connected with the positioning holes on the suction wheel 53, so as to adapt to the use of steel bars of different diameters and facilitate the production of steel bar cages of different diameters;

[0055] The top of the auxiliary positioning plate 31 is also fixedly connected to the main water pipe 34, and the main water pipe 34 is connected to the main water pipe 34. The multiple groups of delivery pipes 35 are respectively connected to the interior of the adjacent communicating cylinders 33, and each group of delivery pipes 35 is provided with a solenoid valve. The liquid inlet end of the main water pipe 34 is connected to the connecting pipe 37;

[0056] Specifically, when in use, one end of the steel bar is first placed on the placement groove on the auxiliary support plate 28, and the steel bar is pushed to make the steel bar enter the auxiliary positioning plate 31 and the connecting tube 33, and the water pump in the liquid storage tank 36 is started to make the water pump deliver the cleaning liquid to the delivery pipe 35 through the connecting pipe 37 and the main water pipe 34, and the solenoid valve on the adjacent delivery pipe 35 is opened to allow the cleaning liquid to enter the corresponding connecting tube 33 and fall on the passing steel bar;

[0057] In this embodiment, the cleaning component 4 includes multiple groups of connecting disks 41, which are respectively fixedly connected to the two ends of the two straightening rollers 22. Each group of connecting disks 41 is fixedly connected to a synchronous push rod 42 on the side away from the synchronous gear 27. Each synchronous push rod 42 is sleeved with a synchronization frame 43. Each synchronization frame 43 is fixedly connected to two groups of limit rods on the side away from the connecting disk 41. Multiple synchronization frames 43 are respectively slidably connected to the inner wall of the fixed frame 21 through the limit rods. The cleaning component 4 also includes a first brush plate 45 slidably connected to the fixed frame 21. The first brush plate 45 is located near the fixed frame 21. On the side near the first positioning assembly 5, the top of the first brush plate 45 is slidably connected to the second brush plate 46, and the multiple synchronization frames 43 are fixedly connected to the side of the first brush plate 45. The ends of the two upper connecting rods 44 away from the synchronization frame 43 are fixed to the two sides of the second brush plate 46, and the ends of the two lower connecting rods 44 away from the synchronization frame 43 are fixed to the two sides of the first brush plate 45. The facing surfaces of the first brush plate 45 and the second brush plate 46 are provided with connecting grooves 47 adapted to the multiple groups of extrusion grooves. The bottom of the first brush plate 45 is also connected to a drain pipe 48 for discharging sewage;

[0058] Specifically, when the two straightening rollers 22 rotate, they simultaneously drive the multiple connecting plates 41 to rotate. The connecting plates 41 push the synchronization frame 43 to move through the synchronization push rod 42. The synchronization frame 43 drives the first brush plate 45 and the second brush plate 46 to move through the connecting rod 44. When the straightening rollers 22 rotate, they simultaneously generate thrust on the steel bars, conveying the steel bars forward so that the steel bars enter between the first brush plates 45 and the second brush plates 46. When the first brush plates 45 and the second brush plates 46 move, the steel bars are brushed, and the oil stains or dust on the steel bars are removed with the help of the cleaning liquid on the steel bars. When brushing, the cleaning liquid mixed with the oil stains on the steel bars is discharged through the drain pipe 48.

[0059] The treated steel bars pass through the positioning holes on the suction wheel 53, and the suction wheel 53 absorbs the residual cleaning liquid on the steel bars to prevent the residual cleaning liquid from affecting the subsequent welding work.

[0060] When the synchronization frame 43 moves, the synchronization frame 43 can only move left and right due to the limitation of multiple limiting rods, thereby preventing the connection disk 41 from pushing the synchronization frame 43 to flip when rotating.

[0061] Example 2, refer to Figures 1-11 As shown, the present invention also provides a construction method of a building steel bar positioning structure as follows:

[0062] First, place one end of the steel bar on the placement groove on the auxiliary support plate 28 and push the steel bar to make it enter the auxiliary positioning plate 31 and the connecting tube 33. Start the water pump in the liquid storage tank 36 to make the water pump deliver the cleaning liquid to the delivery pipe 35 through the connecting pipe 37 and the main water pipe 34. Open the solenoid valve on the adjacent delivery pipe 35 to allow the cleaning liquid to enter the corresponding connecting tube 33 and fall on the passing steel bar.

[0063] When the steel bar moves from the spray assembly 3 to between the two straightening rollers 22, the drive motor 23 is started, and the drive motor 23 drives the second synchronous shaft 25 and the straightening roller 22 to rotate through the first synchronous shaft 24 and the drive belt 26. The two straightening rollers 22 rotate simultaneously under the action of the synchronous gear 27, squeezing the passing steel bar and straightening the steel bar. When the straightening rollers 22 rotate, they also generate thrust on the steel bar, transporting the steel bar forward, so that the steel bar enters between the first brush plate 45 and the second brush plate 46;

[0064] When the two straightening rollers 22 rotate, they simultaneously drive the multiple connecting plates 41 to rotate. The connecting plates 41 push the synchronization frame 43 to move through the synchronization push rod 42. The synchronization frame 43 drives the first brush plate 45 and the second brush plate 46 to move through the connecting rod 44, and brushes the steel bars between the first brush plate 45 and the second brush plate 46. The cleaning liquid on the steel bars is used to remove oil stains or dust on the steel bars. During the brushing process, the cleaning liquid mixed with oil stains and the like on the steel bars is discharged through the drain pipe 48.

[0065] The cleaned steel bar passes through the positioning hole on the water suction wheel 53. When the steel bar passes through the water suction wheel 53, the cleaning liquid remaining on the steel bar will be absorbed by the water suction wheel 53. The steel bar passing through the positioning hole on the water suction wheel 53 continues to move until it passes through the positioning hole on the positioning gear plate 63. When the steel bar touches the sensor switch 68 on the second connecting seat 62, the sensor switch 68 sends a signal to start the third servo motor 65, which drives the driving gear 66 to rotate. The positioning gear plate 63 rotates synchronously under the drive gear 66, causing the water suction wheel 53 and the positioning gear plate 63 to rotate, so that the next positioning hole is rotated to be level with the first brush plate 45, and then other steel bars are inserted, and the above process is repeated.

[0066] When the steel cage is completed, the fixing sleeve 55 is removed and the second servo motor 18 is started. The second servo motor 18 drives the second transmission screw 17 to rotate. The second transmission screw 17 drives the second support frame 61 and the second connecting seat 62 to slide through the sliding seat 67, so that the second connecting seat 62 drives the positioning gear plate 63 to move away from the first positioning assembly 5. The positioning gear plate 63 simultaneously drives the synchronization rod 64 to be pulled out of the water suction wheel 53.

[0067] When the sliding seat 67 moves to the end of the second limiting groove 16, the second servo motor 18 is turned off, and the synchronization rod 64 is rotated to remove the synchronization rod 64 from the positioning gear plate 63, and then a crane is used to lift the steel cage from the positioning gear plate 63.

[0068] It should be noted that the drive motor, servo motor, induction switch and other devices in this application are all common devices in the market. They can be selected according to specific needs during specific use, and the circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection part. Those skilled in the art can implement it relatively easily. It belongs to the existing technology and will not be elaborated on.

[0069] It should be noted that any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present invention should also be within the scope of protection of the present invention.
