Description

Technical Field

[0001] The utility model relates to the technical field of assembled building construction, and in particular to a BIM-based assembly prefabricated structure positioning processing device. Background Art

[0002] Prefabricated buildings are a widely used building structure in modern building construction. With the widespread application of BIM technology in various stages of construction projects, prefabricated buildings have achieved faster and higher-quality development in all aspects from design, production to construction.

[0003] In prefabricated building structures, when assembling the prefabricated concrete column crane with the column crane base completed in advance on the foundation, the prefabricated steel bar structure of the column crane base needs to be aligned and inserted into the socket reserved on the bottom side of the prefabricated column crane. However, the protruding length of the prefabricated steel bar structure of the column crane base is limited, and when encountering some larger prefabricated column cranes, the number of assembled and inserted steel bars and sockets that need to be aligned at the same time is large, and it is more difficult to lower the prefabricated column crane and align it with the column crane base.

[0004] In the face of the above problems, the existing methods are generally to have workers lie directly on the ground near the base of the column crane to observe the plug-in and matching positions of the prefabricated steel bars at the base of the column crane and the plug-in and matching positions of the bottom side sockets of the assembled column crane, or to use conventional reflectors to reflect and observe the plug-in and matching positions of the prefabricated steel bars at the base of the column crane and the plug-in and matching positions of the bottom side sockets of the assembled column crane.

[0005] However, the above observation and alignment method is too close to the construction position between the unstable prefabricated column crane and the column crane base, which may pose a safety hazard (the prefabricated column crane is hoisted by a hanging basket, and generally has no other safety protection. If there is a problem with the hoisting structure, the extremely heavy prefabricated column crane will be a major source of danger). In addition, it is very inconvenient to align by observing at the side, and several collisions back and forth during alignment may cause the prefabricated steel bars at the column crane base to bend or the opening of the socket on the bottom side of the prefabricated column crane to be gapped.

[0006] How to solve the construction safety issues and precise alignment and installation problems that arise during the assembly process of the above-mentioned prefabricated column crane and column crane base has become a difficult problem. Utility Model Content

[0045] Based on the above-mentioned embodiment technical solution of a BIM-based assembly prefabricated structure positioning processing device, this embodiment also designs a BIM-based assembly prefabricated structure positioning processing method, the main process is as follows:

[0046] First, place and fix the counterweight chassis 3 beside the empty space of the column hanging base 1, and lift the lifting and rotating member 6 along the rotating square rod 405 until the positioning plate 8 is higher than the highest point of the protruding steel bar 101 of the column hanging base 1.

[0047] The second step is to rotate the outer ring body 602 of the lifting and rotating member 6, rotate the positioning plate 8 to be directly above the protruding steel bar 101 of the column suspension base 1, and use the low-position support member 5 to support the lifting and rotating member 6 at the current height position.

[0048] The third step is to adjust the lateral position of the transverse sliding plate 401, and adjust the inclination angle of the rotating square rod 405 through the angle adjuster 406. At the same time, the lower alignment hole 8011 of the positioning plate 801 is aligned with the protruding steel bar 101 directly below by rotating the outer ring body 602 of the lifting and rotating member 6. Figure 5 , release the support of the low-position support member 5 on the lifting and rotating member 6, insert the upper side end of the protruding steel bar 101 into the lower alignment hole 8011 of the positioning plate 801, and fasten the relative position of the outer ring body 602 and the inner ring body 601 through the third fastener 604.

[0049] In the fourth step, the assembled column crane 2 is moved to a certain distance above the column crane base 1 by a crane. The lifting and rotating member 6 and the positioning plate 8 are continuously lifted upward until the upper alignment protruding tube 802 of the positioning plate 801 contacts the bottom surface of the assembled column crane 2.

[0050] Step 5: Conclusion Figure 6 , adjust the position of the assembled column hanger 2 until the upper alignment protrusion 802 of the positioning plate 801 is aligned with the assembly installation groove 201 on the bottom side of the assembled column hanger 2, and continue to lift the lifting and rotating part 6 and the positioning plate 8 upwards, insert the upper alignment protrusion 802 of the positioning plate 801 into the assembly installation groove 201 on the bottom side of the assembled column hanger 2, and use the low-position support member 5 to support the lifting and rotating part 6.

[0051] Combination Figure 7 , adjust the position of the positioning sliding frame 701 of the marking positioning piece 7 on the rotating square rod 405, and rotate the transverse marking screw 705 until the front end of the transverse marking screw 705 contacts the appropriate position on the side of the assembled column hanger 2, and use a marking pen to draw a column hanger alignment mark 9 on the area around the contact position. For example, you can draw a circle on the side of the assembled column hanger 2 along the periphery of the transverse marking screw 705.

[0052] Step 6: Release the support of the lower support member 5 on the lifting and rotating member 6, and slowly lower the assembled column suspension 2. At the same time, the lifting and rotating member 6 and the positioning plate 8 are lowered synchronously. When the distance between the bottom side of the assembled column suspension 2 and the upper side end of the protruding steel bar 101 of the column suspension base 1 is no more than 3H, H is the thickness dimension of the positioning plate 8 in the vertical direction. Fig. 9 , Fig.10 , release the third fastener 604 from fixing the position of the outer ring body 602, separate the positioning plate 8 from the bottom side of the assembled column suspension 2, rotate the outer ring body 602, and pull the positioning plate 8 out from between the bottom side of the assembled column suspension 2 and the upper side end of the protruding steel bar 101 of the column suspension base 1.

[0053] Finally, the assembled column hanger 2 continues to slowly descend, and the real-time position of the marking positioning member 7 is adjusted, and the front end of the transverse marking screw 705 is used to perform real-time dynamic alignment with the column hanger alignment mark 9 on the side of the assembled column hanger 2 until the protruding steel bar 101 of the column hanger base 1 is inserted into the assembly installation groove 201 of the assembled column hanger 2.
