Prefabricated buildings are assembled on site through batch production in factories. Because of its factory production, the quality of components can be effectively controlled, environmental pollution can be effectively reduced, and at the same time, the efficiency can be improved.

[0003] The steel bar connection of the existing prefabricated building structure is mainly divided into wet connection and dry connection. Among them, the wet connection mainly uses sleeve grouting, and there are problems such as difficult to control the grouting quality and complex manual operation in the grouting process. The dry connection mainly includes bolt connection, mechanical connection and other methods. During actual construction, due to the deviation of the relative positions of the reserved steel bars of precast components, problems such as misalignment of steel bars between precast concrete components and uneven spacing lengths are likely to occur. And the existing steel bar connectors lack a certain deviation adjustment function and cannot automatically realize the connection of steel bars with positioning deviation, which brings great inconvenience to actual construction. Moreover, the operation is complex, completed by manual operation, and the production efficiency is low, and it cannot achieve intelligence and automation.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] like Figures 1 to 9 As shown, a steel bar connector between precast concrete components for construction provided by an embodiment of the present invention includes a steel bar 1-2 connected to a threaded sleeve 3 through a thread, a motor 6-4 and a motor 7-4 are installed in an intelligent control device 4, a motor 7-4 is connected to a horizontal threaded sleeve 3 through an intelligent lifting device 7-2 and an intelligent rotating device 7-1, a motor 6-4 is connected to a docking rotating lifting device 8 through an intelligent lifting device 6-2 and an intelligent rotating device 6-1, and a motor 8-4 of the docking rotating lifting device 8 is installed in an intelligent grabbing device 2. An intelligent fastening device 5 is installed outside the intelligent grabbing device 2.

[0044] refer to Figure 1 The intelligent steel bar identification device 4-1 at the top of the intelligent control device 4 automatically locates the position and angle of the steel bars to be connected.

[0045] The above scheme is adopted: the intelligent steel bar identification device 4-1 transmits data to the logic processing unit 4-2 installed in the intelligent control device 4 to calculate the required correction value, and the deflection angle adjustment is achieved by commanding the rotation of the gear 8-5 of the docking rotating jacking device 8 and the rotation of the intelligent rotating device 2 6-1 of the vertical rotating jacking device 6, and the offset adjustment is achieved by commanding the lifting and lowering of the vertical rotating jacking device 6, the rotation of the intelligent rotating device 1 7-1, and the lifting of the intelligent jacking device 1 7-2.

The other side of the second threaded sleeve 2-4 is provided with a guide rail opening that matches the intelligent lifting device 8-2. The intelligent clamping device 2 is equipped with a third motor 8-4, and the third motor 8-4 drives the third threaded rod 8-3 to rotate, thereby driving the intelligent lifting device 8-2 to lift along the guide rail. The intelligent rotating device 8-1 is installed at the top of the intelligent lifting device 8-2, and the intelligent fastening device 5 is installed outside the intelligent clamping device 2.

[0047] Adopting the above solution: after the docking deflection angle and deviation are adjusted, the four annular calipers 2-2 are tightened electrically and bite the reinforcing bar 1-1 to be docked, so as to eliminate the system judgment error. Subsequently, the docking rotary lifting device 8 rotates and lifts, so that the reinforcing bar 1-1 to be docked is screwed into the second threaded sleeve 2-4, thereby fixing the docking reinforcing bar. Finally, the intelligent fastening device 5 tightens the annular throat hoop 5-2 through the intelligent tightening device 5-1 to bite with the groove 2-3 reserved outside the annular caliper 2-2, thereby realizing the fastening of the docking.

The intelligent steel bar recognition device 4-1 at the top of the intelligent control device 4 automatically recognizes the position of the steel bar to be docked, and the logic processing unit 4-2 calculates the parameters to be adjusted according to the calculation.

[0050] Subsequently, press the start button 4-4 on the connector again. According to the calculation result, the logic processing unit 4-2 commands the docking rotary lifting device 8 to rotate through the gear 8-5 and cooperate with the intelligent rotating device 6-1 installed on the vertical rotary lifting device 6 to complete the correction of the docking deflection angle. Then the logic processing unit 4-2 commands the vertical rotary lifting device 6 and the horizontal rotary lifting device 7 to rotate and lift to complete the adjustment of the docking distance.

[0051] Subsequently, the logic processing unit 4-2 commands the intelligent grasping device 2 to clamp the reinforcing bar to be docked. At this time, the system docking error is corrected by the intelligent grasping device 2, and the docking rotary lifting device 8 is started to rotate and push the threaded opening at the top of the intelligent grasping device 2 to dock with the reinforcing bar to be docked. Finally, the logic processing unit 4-2 automatically judges the docking situation and commands the intelligent fastening device 5 to perform the fastening operation. After the fastening is completed, the system automatically cuts off the power.
