Description

Technical Field

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

[0002] Steel bars are an important part of building structures. During the building construction process, multiple steel bars are usually made into a steel bar cage by welding or binding. In building engineering, the steel bar cage mainly plays a role in resisting tension. Because the compressive strength of concrete is high but the tensile strength is low, the steel bar cage plays a restraining role on the pile body concrete, enabling it to bear a certain axial tension and horizontal force, thereby improving the bearing capacity of the concrete structure; During the production, transportation, and storage of steel bars, various impurities will inevitably be contaminated. If these impurities are not cleaned up, it will seriously affect the bonding strength between the steel bars and other materials, and further reduce the overall engineering quality of the building. At the same time, during the production, transportation, and storage of steel bars, the steel bars are prone to bending deformation, which brings difficulties to subsequent positioning welding work.

[0013] The present invention also provides a construction method for a building steel bar positioning structure. The method includes the following steps: S1. Steel bar pretreatment: First, insert the steel bar into the spraying assembly through the auxiliary support plate. At the same time, start the water pump in the liquid storage tank, and spray the cleaning liquid in the liquid storage tank onto the steel bar located in the communication cylinder through the main water pipe and the conveying pipe; S2. Straightening of steel bars: The steel bars sprayed with cleaning liquid enter between two groups of straightening rollers through the connecting cylinder. At this time, the driving motor starts, driving the two groups of straightening rollers to rotate, and straightening the steel bars under the extrusion of the two groups of straightening rollers; S3. Cleaning of steel bars: The steel bars straightened by the straightening rollers enter between the first brush plate and the second brush plate. At this time, the straightening rollers continue to rotate. When the straightening rollers rotate, they drive multiple connecting disks to rotate at the same time, so that the synchronous push rods push 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 rods, and brush the steel bars located between the first brush plate and the second brush plate; S4. Positioning of steel bars: The steel bars after being brushed are pushed out from between the first brush plate and the second brush plate by the straightening rollers and pass through the positioning holes on the water absorption wheel. When the steel bars pass through the water absorption wheel, the residual cleaning liquid on the steel bars will be absorbed by the water absorption wheel. The steel bars passing through the positioning holes on the water absorption wheel continue to move until they pass through the positioning holes on the positioning gear disk. When the steel bars touch the induction switch on the second connecting seat, the induction switch sends a signal to start the third servo motor. The third servo motor drives the driving gear to rotate, and the positioning gear disk rotates synchronously under the drive of the driving gear, so that the water absorption wheel and the positioning gear disk rotate, and the next positioning hole rotates to be horizontal with the first brush plate, and then other steel bars are inserted, repeating the above work.

[0014] Technical effects and advantages of the present invention: In the present invention, when the steel bars enter the spraying assembly, the cleaning liquid can be sprayed on the surface of the steel bars. Subsequently, the steel bars enter between the first brush plate and the second brush plate. Driven by the rotation of the straightening rollers, the connecting disks, synchronous push rods, synchronous frames and connecting rods cooperate to make the first brush plate and the second brush plate brush the steel bars. With the help of the cleaning liquid, the oil stains or dust on the steel bars can be effectively removed. The sewage after brushing is discharged in time through the drain pipe to ensure the cleanliness of the steel bar surface, providing a good foundation for subsequent processing and use, and avoiding the influence of impurities on the bonding strength between the steel bar and other materials and the overall project quality.

[0015] In the present invention, the driving motor can drive the second synchronous shaft and the straightening rollers to rotate through the first synchronous shaft and the driving belt. The two straightening rollers rotate simultaneously under the action of the synchronous gears, extruding and straightening 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 at the same time ensure that the steel bars can exert their due mechanical properties in the concrete structure, enhancing the stability and safety of the building; Meanwhile, multiple sets of extrusion grooves are provided on the straightening roller. Appropriate extrusion grooves can be selected 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 fixing frame moves on the support seat, enabling different extrusion grooves on the straightening roller to communicate with the positioning holes on the water absorption wheel, further adapting to the use of steel bars with different diameters, facilitating the production of steel cages with different diameters, without the need to frequently replace equipment or components, reducing the construction cost and time cost.

Start the straightening component 2 to straighten the steel bars through the straightening component 2, facilitating subsequent welding or bundling work. When the steel bars pass through the spraying component 3, the spraying component 3 simultaneously sprays the cleaning liquid on the steel bars. After the steel bars are straightened by the straightening component 2, they enter the cleaning component 4 under the push of the straightening component 2.

[0020] Embodiment 2, refer to Figures 1 - 11 As shown, the present invention also provides a construction method for a building steel bar positioning structure as follows: 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 the steel bar enter the auxiliary positioning plate 31 and the communication cylinder 33. Start the water pump in the liquid storage tank 36, so that the water pump conveys the cleaning liquid through the connecting pipe 37 and the main water pipe 34 into the conveying pipe 35. Open the solenoid valve on the adjacent conveying pipe 35, so that the cleaning liquid can enter the corresponding communication cylinder 33 and fall on the passing steel bar; When the steel bar moves from the spraying assembly 3 to between the two straightening rollers 22, start the driving motor 23.

The connecting plates 41 push the synchronous frame 43 to move through the synchronous push rods 42. The synchronous frame 43 drives the first brush plate 45 and the second brush plate 46 to move through the connecting rods 44, brushing the steel bar located between the first brush plate 45 and the second brush plate 46, removing oil stains, dust, etc. on the steel bar with the cleaning liquid on the steel bar. When brushing, the cleaning liquid mixed with oil stains on the steel bar is discharged through the drain pipe 48; The steel bars after brushing pass through the positioning holes on the water-absorbing wheel 53. When the steel bars pass through the water-absorbing wheel 53, the cleaning liquid remaining on the steel bars will be absorbed by the water-absorbing wheel 53. The steel bars passing through the positioning holes on the water-absorbing wheel 53 continue to move until they are inserted into the positioning holes on the positioning gear disc 63. When the steel bars touch the induction switch 68 on the second connecting seat 62, the induction switch 68 emits a signal to start the third servo motor 65. The third servo motor 65 drives the driving gear 66 to rotate. The positioning gear disc 63 rotates synchronously driven by the driving gear 66, causing the water-absorbing wheel 53 and the positioning gear disc 63 to rotate, so that the next positioning hole rotates to be horizontal with the first brush plate 45, and then other steel bars are inserted, repeating the above work; When the steel bar cage is manufactured, 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 disc 63 to move away from the first positioning assembly 5, and the positioning gear disc 63 simultaneously drives the synchronizing rod 64 to be withdrawn from the water-absorbing wheel 53; When the sliding seat 67 moves to the end of the second limiting groove 16, the second servo motor 18 is turned off. At this time, the synchronizing rod 64 is rotated, the synchronizing rod 64 is taken out from the positioning gear disc 63, and then the steel bar cage is lifted out from the positioning gear disc 63 by using a crane.
