[0027] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0028] The invention discloses a device for planting steel bars, which is equipment used in construction engineering and is used for planting steel bars in a concrete slab or a concrete body.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the device mainly includes a positioning part, a holding part and a steel bar clamping part. The positioning part is used to coordinate with a reference object such as a wall for positioning to ensure the convenience of operation and the accuracy of planting reinforcement. The holding part is used for workers to operate by hand, and the two sides of the holding part are respectively connected to the positioning part and the steel bar clamping part. The holding part includes a hand-held rod 1 and a column clamp 2, one end of the column clamp 2 is connected to the positioning part and the other end is connected to the steel bar clamping part, and the middle part of the column clamp 2 is provided with a hand-held rod 1. The steel bar clamping part includes a reinforcement tube 3 that guides the reinforcement and a stop mechanism that clamps the reinforcement in the reinforcement tube 3. When in use, the reinforcement is inserted into the reinforcement tube 3 and then fixed in the reinforcement tube 3 by the stop mechanism. The hand-held rod 1 is held by hand to insert the reinforcement into the reinforcement insertion hole with the cooperation of the positioning part.

[0030] like Figure 3 As shown, the column clamp 2 is provided with two clamping cylinders 2-1, and the two clamping cylinders 2-1 respectively fix and clamp the hand-held rod 1 and the rib cylinder 3.

[0031] In the present invention, a stopper mechanism is provided to fix the steel bars in the steel tube 3, and the stopper mechanism needs to have two states: clamping and loosening. The preferred structure is as follows: Figure 4 As shown, the stop mechanism includes a hinge clamp 4 sleeved outside the reinforcement tube 3 and a stop block 5 hinged to the hinge clamp 4. The stop block 5 can rotate around the hinge shaft under the drive of an external force, thereby achieving the tightening and stopping of the reinforcement. The stop block 5 is used to fix the reinforcement in the reinforcement tube 3 during the rotation process.

[0032] like Figure 5 , Figure 6 As shown, the stop block 5 includes an integrally arranged ribbed end 5-1 and a driving end 5-2, the ribbed end 5-1 and the driving end 5-2 are respectively located on both sides of the hinge shaft, and a stop line 6 is arranged at the driving end 5-2. The stop line 6 is used to apply an external force, and the stop line 6 pulls the driving end 5-2 to rotate the stop block 5 as a whole, the driving end 5-2 of the stop block 5 is away from the tendon tube 3, and the ribbed end 5-1 of the stop block 5 is close to the tendon tube 3 and can press the steel bar into the tendon tube 3. Furthermore, in order to ensure the rib-pressing effect of the stop block 5 on the steel bar, a ribbed pattern 5-3 is arranged on the side of the ribbed end 5-1 facing the tendon tube 3, which can increase the friction force. In a specific implementation, the stop line 6 can be set as a steel wire.

[0033] The rebar planting device is used for planting steel bars. During the rebar planting process, the steel bars are fastened in the rebar tube. After the rebar planting is completed, the steel bars need to be released from the rebar tube, that is, the stop block 5 of the stop mechanism is loosened. In order to be able to loosen the stop block 5, it is necessary to rotate the stop block 5 in the opposite direction, which requires an external force to drive the driving end of the stop block 5 to rotate in the opposite direction. The following structure can be adopted, in which a matching reset block 7 is set for the stop mechanism to drive the stop block 5 to return to its original position. The reset block 7 is arranged opposite to the stop block 5, and the reset block 7 can also rotate. Figure 4As shown, two hinge hoops 4 are provided outside the rib tube 3, one of which is used for hingedly setting the stop block 5, and the other hinge hoop 4 is used for hingedly setting the reset block 7. The reset block 7 includes an integrally arranged reset toggle end 7-1 and a pulling end 7-2, and the reset toggle end 7-1 and the pulling end 7-2 are respectively located on both sides of the hinge shaft. The pulling end 7-2 of the reset block 7 can rotate under the action of an external force, so that the reset block 7 rotates around the hinge shaft as a whole. The reset toggle end 7-1 of the reset block 7 is used to toggle the stop block 5 back to its original position. The specific structure is that the stop block 5 is integrally provided with a return platform 5-4 between the rib end 5-1 and the driving end 5-2, and the driving end 5-2 and the return platform 5-4 are on the same side of the hinge shaft of the stop block 5. The reset toggle end 7-1 is located outside the return platform 5-4, and the reset toggle end 7-1 can be pressed toward the return platform 5-4. At this time, the driving end 5-2 on the coaxial side of the return platform 5-4 is close to the rib tube 3, while the pressing end 5-1 on the non-coaxial side of the return platform 5-4 is away from the rib tube 3. The pressing end 5-1 is away from the rib tube 3 and the steel bars at the same time, thereby releasing the steel bars, and the device can be separated from the steel bars.

[0034] The stop block 5 of the release stop mechanism may also be configured as follows: the stop wire 6 is configured as a wire with rigidity, and the stop wire 6 can both pull the driving end 5 - 2 of the stop block 5 and push the driving end 5 - 2 of the stop block 5 .

[0035] The stop block 5 of the release stop mechanism can also be set as follows: a torsion spring is set at the hinge shaft of the stop block 5 and the hinge clamp 4. Under the torsion of the torsion spring, the stop block 5 is in a normally closed state. Before planting the reinforcement, a pulling force is applied to the stop line 6 to open the stop block 5 to insert the reinforcement into the reinforcement tube 3, and then the stop line 6 is released, and the torsion spring drives the stop block 5 to automatically clamp the reinforcement. After the reinforcement is planted, a pulling force is applied to the stop line 6 to open the stop block 5 to release the reinforcement from the reinforcement tube 3.

[0036] The reinforcement tube 3 of the device is used to guide the reinforcement and cooperate with the stop mechanism to tighten the reinforcement. The stop block 5 of the stop mechanism is located outside the reinforcement tube 3 and presses the reinforcement. In order to improve the pressing effect of the stop block 5, an extended strip 14 is provided at the opposite sides of the reinforcement tube corresponding to the reinforcement pressing end 5-1 of the stop block 5 and the pulling end 7-2 of the reset block 7. Figure 4 When the stop block 5 presses the steel bar, the extended strip 14 and the steel bar pressing end 5 - 1 of the stop block 5 are located at both sides of the steel bar correspondingly, so as to provide a support point for the stop block 5 .

[0037] The rebar planting device of the present invention is also provided with a positioning part for positioning when cooperating with a wall or the like for rebar planting. The positioning part includes a support plate 8 positioned closely against the wall, a clamping plate 9 for supporting the holding part, and a light rod 10 and an adjusting screw 11 fixed on the same side of the support plate 8. The outer end of the light rod 10 passes through the clamping plate 9, and the light rod 10 plays a supporting and guiding role for the movement of the clamping plate 9. The outer end of the adjusting screw 11 passes through the clamping plate 9 and is provided with an adjusting screw sleeve 12, and the clamping plate 9 is movably connected to the adjusting screw sleeve 12. The adjusting screw sleeve 12 is threadedly connected to the adjusting screw 11, and the rotation of the adjusting screw sleeve 12 can adjust the position of the clamping plate 9.

[0038] The clamping plate 9 is movably connected to the adjusting screw sleeve 12, and the adjusting screw sleeve 12 can drive the clamping plate 9 to move linearly and rotate freely. Figure 2 As shown, a clamping plate 13 is arranged on the outer side of the clamping plate 9, and a clamping ring 12-1 is arranged on one end of the adjusting screw sleeve 12. The outer end opening of the clamping plate 13 is small, and the clamping ring 12-1 is located inside the clamping plate 13. The adjusting screw sleeve 12 is not directly connected to the clamping plate 13, but through the interaction between the clamping ring 12-1 and the clamping plate 13, the clamping plate 9 can be driven to move when the adjusting screw sleeve 12 rotates.

[0039] The present invention is used as follows: the steel bar is placed in the steel tube 3, and the stop wire 6 is tightened. At this time, the position of the steel bar 15 in the steel tube 3 is fixed, and the steel bar 15 is inserted into the hole of the top plate and pumped back and forth to exhaust air according to the construction process. After the pumping time reaches the specified requirement, the stop wire 6 is released, and the reset wire 16 is tightened. At this time, the steel bar 15 is separated from the steel tube 3, and the reinforcing bar planting operation is completed.

[0040] The device for planting rebars of the present invention is provided with three functional parts, namely, a positioning part, a holding part and a steel bar clamping part. The three functional parts cooperate with each other to realize fast and accurate steel bar planting operation. The positioning part can adjust the positioning distance, which ensures that the steel bar planting operation complies with the drawings and requirements, making the device more adaptable. The steel bar clamping part can adjust the tightness. After the steel bar is inserted into the top plate during the steel bar planting process, the steel bar can be inserted and pulled out through the holding part, thereby ensuring the quality of the steel bar planting operation. The steel bar clamping part adopts a stop mechanism, so that the operator can clamp and loosen the steel bar at the holding end to ensure the safety of the personnel's work. The device has a reasonable structure, is easy to use, and is simple to operate. It improves the accuracy, convenience and safety of the steel bar planting operation and realizes a highly efficient steel bar planting operation.
