Description

Technical Field

[0001] The utility model relates to the technical field of steel bar positioning, in particular to a steel bar positioning structure for building construction. Background Art

[0002] In construction, after the steel bars are inserted and fixed into the corresponding reserved holes in the concrete floor, in order to ensure the stability of the steel bars during the subsequent pouring process, positioning mechanisms are generally used to perform multi-stage positioning operations on the steel bars. These positioning mechanisms can effectively fix the position of the steel bars to prevent them from displacement or offset during the pouring process, thereby ensuring the stability and safety of the entire building structure.

[0003] Existing steel bar positioning mechanisms are usually installed one by one on the outer surfaces of multiple steel bars from top to bottom. This operation method requires workers to squat repeatedly to complete the installation, which undoubtedly increases the physical exertion of workers. Secondly, during the installation process, due to the sharp edges that may exist on the top of the steel bars, the workers' hands are very easy to be scratched, which undoubtedly increases the safety risk; in addition, in order to reduce the rust of steel bars during storage and transportation, anti-rust oil is generally applied to the outside of the steel bars. However, the application of anti-rust oil will seriously affect the subsequent fixing operation of the fixing ring on the steel bar in the positioning mechanism, because the presence of anti-rust oil may cause the fixing ring to fail to fit tightly to the surface of the steel bar, resulting in poor fixing effect, thereby affecting the overall positioning stability of the positioning mechanism.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5, a steel bar positioning structure for construction, comprising four steel bars 1, the outer sides of the four steel bars 1 are respectively equipped with two L-shaped positioning seats 2, a large V-shaped positioning seat 3 and a small V-shaped positioning seat 4, the large V-shaped positioning seat 3 and the corresponding ends of the two L-shaped positioning seats 2 or the small V-shaped positioning seat 4 and the corresponding ends of the two L-shaped positioning seats 2 are respectively provided with adjustment mechanisms, the adjustment mechanism comprises two guide cylinders 5, the two guide cylinders 5 are fixedly installed in the fixed grooves opened inside the large V-shaped positioning seat 3 or the two L-shaped positioning seats 2, the guide cylinders 5 are slidably inserted with guide rods 6 inside, the telescopic ends of the front or rear guide rods 6 are fixedly connected to the small V-shaped positioning seat 4 and the corresponding ends of the left L-shaped positioning seat 2, the telescopic ends of the left or right guide rods 6 are movably connected to the small V-shaped positioning seat 4 and the corresponding ends of the front L-shaped positioning seat 2, the adjustment mechanism also comprises two groups of connecting plates 11, the two groups of connecting plates 11 are fixedly installed at the two ends of the large V-shaped positioning seat 3 or the left ends and front ends of the two L-shaped positioning seats 2, and the inside of one group of connecting plates 11 and close to the The two sides are respectively fixed with a sliding rod 12 and a threaded rod 13 which is rotatably installed. The outer surface of the threaded rod 13 is covered with two fixing blocks 14 with threaded matching. The outer surface of the sliding rod 12 is slidably matched with the corresponding inner parts of the two fixing blocks 14. The inner ends of the two fixing blocks 14 are fixedly matched with the sliding grooves opened on the upper and lower sides of the guide rod 6. The bottom ends of the four steel bars 1 are inserted and fixed on the concrete ground. A resistance rubber ring is arranged on the inner side of the guide cylinder 5 and on the outer side of the guide rod 6. The worker appropriately pulls the distance between the small V-shaped positioning seat 4 and an L-shaped positioning seat 2, or the large V-shaped positioning seat 3 and the other L-shaped positioning seat 2 according to the actual spacing between the two horizontal steel bars 1. Then, according to the spacing between the two longitudinal steel bars 1, the corresponding guide rod 6 is driven to slide out of the guide cylinder 5 by pulling the two screws 15. Since a resistance rubber ring is arranged inside the guide cylinder 5 and on the outer side of the guide rod 6, the guide rod 6 can remain fixed without applying a large external force after being adjusted to a suitable position.

[0023] The telescopic end of the left or right guide rod 6 is rotatably connected with a screw 15, and the front ends of the two screws 15 are respectively threadedly matched with the fixing holes opened at the corresponding ends of the small V-shaped locating seat 4 and the right L-shaped locating seat 2. The worker will adjust the spacing of the small V-shaped locating seat 4 and an L-shaped locating seat 2 combination and put them on the outside of the two front transverse steel bars 1, and rotate the threaded rod 13 so that the two fixing blocks 14 are close to each other and clamp and fix the corresponding guide rod 6. Subsequently, another L-shaped locating seat 2 and the large V-shaped locating seat 3 are put on the outside of the two rear transverse steel bars 1, and the front ends of the two screws 15 are inserted into the fixing holes opened at the corresponding ends of the small V-shaped locating seat 4 and the L-shaped locating seat 2, and the screws 15 are rotated to press them against the outside of the fixing holes, thereby completing the positioning operation of the steel bar 1 from the outside, thereby effectively avoiding the risk of workers having to squat repeatedly and being scratched by the sharp edge of the top of the steel bar 1 during the installation process.

[0024] Anti-skid fixing mechanisms are respectively arranged on the upper surfaces of two L-shaped positioning seats 2, a large V-shaped positioning seat 3 and a small V-shaped positioning seat 4 and at corresponding positions located on the outer side of the steel bar 1. The anti-skid fixing mechanism includes an extrusion bag 7, the upper end of the extrusion bag 7 is fixedly connected to a fixing ring 9 through a telescopic hose 8, a guide cavity is arranged inside the fixing ring 9 and a plurality of spray holes 10 are opened on the inner side of the fixing ring 9, the anti-skid fixing mechanism also includes a mounting seat 19, the mounting seat 19 is fixedly mounted on the upper surfaces of the L-shaped positioning seat 2 or the small V-shaped positioning seat 4 and the large V-shaped positioning seat 3, a rotating shaft 16 is rotatably mounted in the middle of the mounting seat 19, the upper end of the rotating shaft 16 is fixedly connected to one end of the fixing ring 9 through a connecting piece, a rotating member 17 is fixedly sleeved on the outer surface of the rotating shaft 16 and located below the fixing ring 9, and a rotating member 17 is fixedly mounted on one side of the rotating shaft 16 and located below the rotating member 17 The movable plate 23 and the upper surface of the mounting seat 19 are fixedly installed with a fixing piece. An arc guide rod 20 is installed around the same side of the two fixing pieces and located on the outer side of the rotating shaft 16. The interior of the rotating plate 23 slides with the outer surface of the arc guide rod 20. The outer surface of the arc guide rod 20 is sleeved with an arc spring 21. The two ends of the arc spring 21 are arranged between a fixing piece and the rotating plate 23. A threaded insertion rod 22 is installed inside the rotating plate 23. The bottom end of the insertion rod 22 is inserted into the insertion hole opened at the corresponding position of the upper surface of the mounting seat 19. The bottom end of the rotating piece 17 is fixedly connected with the extrusion seat 18. Two L-shaped positioning seats 2 and the outer sides of the small V-shaped positioning seat 4 and the large V-shaped positioning seat 3 and located at the rotation corresponding position of the extrusion seat 18 are respectively provided with installation grooves. The interior of the installation groove is fixedly adhered with an extrusion bag 7, and the interior of the extrusion bag 7 stores anti-slip powder. The worker rotates the insertion rod 22 upward so that its bottom end moves out of the insertion hole opened at the corresponding position of the mounting seat 19. Once the insertion rod 22 is separated from the insertion hole, the rotating plate 23 loses the downward insertion resistance of the insertion rod 22. At this time, the arc spring 21 on the rear side begins to exert elastic thrust. Under the push of the arc spring 21, the rotating plate 23 slides along the arc guide rod 20, while driving the rotating shaft 16 and the rotating member 17 to rotate synchronously. As the rotating member 17 rotates, it pushes the extrusion seat 18 to apply pressure to the extrusion bag 7 on the corresponding side. Under the action of pressure, the anti-slip powder stored in the extrusion bag 7 is sprayed into the guide cavity inside the fixing ring 9 through the telescopic hose 8. Then, the anti-slip powder is sprayed to the part of the outside of the steel bar 1 that needs to be fixed through the spray hole opened on the inner side of the fixing ring 9, ensuring that the anti-slip powder can adhere to the outer surface of the steel bar 1, thereby effectively avoiding the influence of the subsequent anti-rust oil on the outer surface of the steel bar 1 on the fixing effect of the fixing ring 9. Finally, the worker squeezes and pushes the fixing ring 9 appropriately to make it firmly clamp the outside of the steel bar 1.

[0025] In the utility model, workers appropriately pull the distance between the small V-shaped positioning seat 4 and one L-shaped positioning seat 2, or the distance between the large V-shaped positioning seat 3 and another L-shaped positioning seat 2, according to the actual spacing between the two horizontal steel bars 1. Then, according to the spacing between the two longitudinal steel bars 1, workers pull the two screws 15 to drive the corresponding guide rod 6 to slide out of the guide cylinder 5. Since a resistance rubber ring is provided inside the guide cylinder 5 and on the outside of the guide rod 6, the guide rod 6 can be kept fixed without applying a large external force after being adjusted to a suitable position.

[0026] Afterwards, the worker will put the small V-shaped positioning seat 4 and an L-shaped positioning seat 2 with adjusted spacing on the outside of the two transverse steel bars 1 on the front side, and rotate the threaded rod 13 to make the two fixing blocks 14 approach each other and clamp and fix the corresponding guide rods 6. Subsequently, another L-shaped positioning seat 2 and a large V-shaped positioning seat 3 are put on the outside of the two transverse steel bars 1 on the rear side, and the front ends of the two screws 15 are inserted into the fixing holes opened at the corresponding ends of the small V-shaped positioning seat 4 and the L-shaped positioning seat 2. The screws 15 are rotated to press them against the outside of the fixing holes, thereby completing the positioning operation of the steel bars 1 from the outside, thereby effectively avoiding the risk of workers having to squat repeatedly and being scratched by the sharp edge of the top of the steel bars 1 during the installation process;

[0027] Afterwards, the worker rotates the insertion rod 22 upward so that its bottom end moves out of the insertion hole opened at the corresponding position of the mounting seat 19. Once the insertion rod 22 is separated from the insertion hole, the rotating plate 23 loses the downward insertion resistance of the insertion rod 22. At this time, the arc spring 21 on the rear side begins to exert elastic thrust. Under the push of the arc spring 21, the rotating plate 23 slides along the arc guide rod 20, and at the same time drives the rotating shaft 16 and the rotating member 17 to rotate synchronously. As the rotating member 17 rotates, it pushes the extrusion seat 18 to apply pressure to the extrusion bag 7 on the corresponding side. Under the action of pressure, the anti-slip powder stored in the extrusion bag 7 is sprayed into the guide cavity inside the fixing ring 9 through the telescopic hose 8. Then, the anti-slip powder is sprayed to the part that needs to be fixed on the outside of the steel bar 1 through the spray hole opened on the inner side of the fixing ring 9, ensuring that the anti-slip powder can adhere to the outer surface of the steel bar 1, thereby effectively avoiding the influence of the subsequent anti-rust oil on the outer surface of the steel bar 1 on the fixing effect of the fixing ring 9. Finally, the worker squeezes and pushes the fixing ring 9 appropriately to make it firmly clamp the outside of the steel bar 1.

[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
