Technical field:
[0001] The utility model relates to the technical field of steel bar binding, in particular to a telescopic box beam top plate steel bar formwork. Background technology:
[0002] During the construction of infrastructure facilities such as highway bridges, cement reinforcement is a commonly used and extremely important method to ensure the strength of concrete structures. In bridge structures, since the bridge body has to bear a relatively large load, a large number of steel bars need to be arranged in the load-bearing structure to ensure the structural strength of reinforced concrete. These large amounts of steel bars need to be professionally calculated and analyzed to obtain reasonable steel bar distribution rules, and then tied together to form a steel skeleton.
[0003] The existing top plate steel bar skeleton binding is to place multiple annular ribs in the positioning comb teeth on the fetal membrane. The annular ribs are placed unevenly on the left and right. The hydraulic cylinder is operated to drive the two push plates to move toward each other to align the multiple annular ribs on the left and right. Since the annular ribs will have a small size deviation during the production process, the push plates push the annular ribs to align them. The two ends of the push plates cannot fit with the smaller annular ribs in the process, resulting in the smaller centered annular ribs not being able to be centered, reducing the quality of the finished steel bar skeleton. Utility model content:
[0004] To this end, the purpose of the present utility model is to provide a telescopic box girder top plate steel bar formwork to overcome the existing technology because the existing top plate steel bar skeleton binding is to place multiple annular ribs in the positioning comb teeth on the membrane, and the annular ribs are placed unevenly on the left and right. The hydraulic cylinder is operated to drive the two push plates to move toward each other to align the multiple annular ribs on the left and right. Since the annular ribs will have a small size deviation during the production process, the push plates push the annular ribs to align them, and the two ends of the push plates cannot fit with the smaller annular ribs in the process, resulting in the smaller centered annular ribs cannot be centered, reducing the quality of the finished steel bar skeleton.

[0024] like Figure 1-Figure 5 When the cam 2 is in the upright position, the hydraulic cylinder 2 is fixed on the upper and lower ends of the support plates 1 and 2 and the hydraulic cylinder 2 is fixed on the upper and lower ends of the support plates 1. When the cam 2 is in the upright position, the hydraulic cylinder 2 is fixed on the upper and lower ends of the support plates 1. When the cam 2 is in the upright position, the hydraulic cylinder 2 is fixed on the upper and lower ends of the support plates 1. When the cam 2 is in the upright position, the hydraulic cylinder 2 is fixed on the upper and lower ends of the support plates 1.
[0025] Please combine Figure 1As shown, during use, when the annular ribs need to be tied to form a steel skeleton, the multiple annular ribs that need to be tied are inserted into the positioning comb teeth on the fetal membrane, and then the hydraulic station is operated to start the hydraulic cylinder 2. The output end of the hydraulic cylinder 2 pushes the push plates 3 on both sides to move toward each other and gradually approach each other. The push plates 3 drive the positioning grooves 4 to gradually approach the annular ribs and get stuck on their side walls. The push plates 3 drive the first compression springs 8 to move, and the first compression springs 8 drive the U-shaped rods 7 to move. The U-shaped rods 7 drive the push rods 6 to move gradually close to the annular ribs and push them to move, so that the two ends of the annular ribs are aligned. At this time, one side of the smaller annular rib is not in contact with the side wall of the push rod 6. The output end of the hydraulic cylinder 2 drives the push plates 3 to move, and the push plates 3 indirectly drive the push rods The rod 6 moves, and the push rod 6 that is not in contact with the smaller annular rib continues to move and gradually contacts the smaller annular rib. The push rod 6 that is in contact with the side wall of the normal-sized annular rib cannot move. The inability of the push rod 6 to move makes the U-shaped rod 7 unable to move. The output end of the hydraulic cylinder 2 drives the push plate 3 to move and squeeze the first compression spring 8 to deform. The push rod 6 that is in contact with the smaller annular rib pushes it to move and gradually contacts the side wall of the push rod 6 corresponding to the other side, thereby realizing the operation of pushing the smaller annular rib to the center. At this time, all the push rods 6 are limited by the annular rib and cannot move. The hydraulic cylinder 2 continues to work and the output end pushes the push plate 3 to move and squeeze the first compression spring 8 to deform, thereby realizing the clamping of the annular rib, and then the binding of the annular rib is carried out.
[0026] After the annular reinforcement is tied, operate the hydraulic station to make the hydraulic cylinder 2 start working, the output end of the hydraulic cylinder 2 drives the push plate 3 to move, the push plate 3 drives the first compression spring 8 to move, the first compression spring 8 drives the U-shaped rod 7 to move, the U-shaped rod 7 drives the push rod 6 to move and separate from the annular reinforcement, the push plate 3 drives the positioning groove 4 to move and separate from the annular reinforcement, and then lift the formed steel bar skeleton, and then tie the annular reinforcement according to the above operation method.
[0027] The width of the positioning groove 4 from 2 / 3 onwards gradually increases in the direction approaching the lashing frame.
[0028] Please combine Figure 3 As shown, during use, in order to facilitate the removal of the annular rib from the positioning comb teeth, the spacing between the positioning comb teeth on the fetal membrane is greater than the diameter of the annular rib. When the annular rib is inserted into the positioning comb teeth, the annular rib is prone to tilt. The moving push plate 3 drives the positioning groove 4 to move and gradually get stuck on the annular rib and push the annular rib to gradually become a vertical state, thereby improving the quality of the finished steel bar skeleton.
[0029] The side wall section of the push rod 6 close to the lashing frame end is a convex arc surface, which reduces the contact area with the annular rib and facilitates the sliding of the annular rib from inclined to vertical.
[0030] The top surface of the push plate 3 is provided with a placement groove 11, and a limit rod 10 is slidingly fitted in the placement groove 11. The limit rod 10 is slidably arranged in the limit groove 9. The limit groove 9 is opened on the side wall of the cross bar at the top of the U-shaped rod 7. The side wall of the push plate 3 is symmetrically provided with two grooves 14. A T-shaped slide bar 12 is fitted and slid in the groove 14. The top of the T-shaped slide bar 12 passes through the push plate 3 and is fixedly connected to the bottom surface of the limit rod 10. The T-shaped slide bar 12 is slidably connected to the push plate 3. A compression spring 13 is fixedly connected between the bottom end of the T-shaped slide bar 12 and the push plate 3. The compression spring 13 is arranged in the groove 14. The top of multiple support plates 1 on one side is fixedly connected to the support plate 15. The bottom surface of the support plate 15 is fitted and slidably fitted with the top surface of the push plate 3. The top surface of the push plate 3 is provided with multiple first sliding grooves 17. A cross bar 16 is fitted and slidably fitted in the first sliding groove 17. The top surface of the cross bar 16 is fixedly connected to the bottom surface of the support plate 15.
[0031] Please combine Figure 1 As shown, during use, the output end of the hydraulic cylinder 2 drives the push plate 3 to move, and the push plate 3 drives the limit rod 10 to move through the placement groove 11. When the push rod 6 stops moving, the U-shaped rod 7 fixedly connected to the stopped push rod 6 stops moving. When all the push rods 6 stop moving, the output end of the hydraulic cylinder 2 continues to indirectly drive the limit rod 10 to move, and the limit rod 10 gradually moves and slides out of the limit groove 9. At this time, the limit groove 9 cancels the limit on the limit rod 10, and the compression spring 13 pushes the T-shaped slide bar 12 to move, and the T-shaped slide bar 12 drives the limit rod 10 to move and slide out of the placement groove 11. At this time, the top surface of the cross bar of the T-shaped slide bar 12 is already in contact with the push plate 3 and cannot continue to move. When the limit rod 10 moves and slides out of the placement groove 11, it is proved that all the annular ribs are centered, and it is easier for the staff to understand whether all the annular ribs are centered before binding.
[0032] After the tying is completed, the hydraulic cylinder 2 is operated to drive the push plates 3 on both sides to move in opposite directions. The push plates 3 indirectly drive the push rods 6 to move and separate from the annular ribs. The deformed first compression spring 8 pushes the U-shaped rod 7 to move, and the U-shaped rod 7 drives the push rod 6 to move and reset. When the side wall of the cross bar at the top of the U-shaped rod 7 fits the surface of the limit rod 10, it stops moving. At this time, the push plate 3 continues to move, and the push plate 3 drives the T-shaped slide bar 12 to move. The T-shaped slide bar 12 drives the limit rod 10 to move gradually close to the support plate 15. The support plate 15 pushes the limit rod 10 to move downward, and the limit rod 10 moves downward. The moving Dinghu pushes the U-shaped rod 7 to move laterally. When the limit rod 10 moves downward and fits into the side wall of the cross bar 16, the cross bar 16 pushes the limit rod 10 to move downward. The limit rod 10 drives the T-shaped slide bar 12 to move and squeeze the compression spring 13 to deform. The limit rod 10 gradually moves downward into the placement groove 11. When the limit rod 10 corresponds to the limit groove 9, the deformed first compression spring 8 pushes the U-shaped rod 7 to move. The U-shaped rod 7 drives the limit groove 9 to move and is stuck on the limit rod 10 to limit it, so that the limit rod 10 cannot move upward.
[0033] The side wall below 2 / 3 of the support plate 15 near the lashing frame end is a slope, and the slope is tilted downward in the direction close to the hydraulic cylinder 2. The side wall of the cross bar 16 near the lashing frame end is a slope, and the plane where the slope is located is in the same plane as the slope of the side wall of the support plate 15.
[0034] Please combine Figure 4 As shown, during use, the support plate 15 and the inclined surface of the cross bar 16 push the limiting rod 10 in sequence to move and reset into the placement groove 11 and get stuck in the limiting groove 9.
[0035] The longitudinal section of the limiting rod 10 is a right-angled trapezoid, and the inclined surface of the limiting rod 10 is arranged to be inclined downward in a direction away from the limiting groove 9, so that the limiting rod 10 moves downward to squeeze the U-shaped rod 7 and push it to move horizontally.
[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
