Description

Technical Field

[0001] This invention relates to the field of curtain wall structure engineering technology, and in particular to a prefabricated splicing device for irregular curved GRC curtain walls based on BIM technology. Background Technology

[0002] GRC is a composite material composed of cement, glass fiber and other additives. Irregular curved GRC curtain walls are curtain wall systems that use GRC materials to construct facades with unconventional shapes and curved surfaces. BIM technology is a digital design and construction method based on three-dimensional models, which can integrate and coordinate various information at all stages of a building project.

[0003] When prefabricating and splicing irregular curved GRC curtain walls based on BIM technology, the process begins with designing and creating a curtain wall model using BIM technology. The curtain wall is then divided and organized according to the splicing method. Next, molds suitable for the prefabricated curtain wall panels are made, taking into account the curved shape and size of the curtain wall and ensuring the molds accurately replicate the design requirements. Subsequently, GRC materials and molds are used to prefabricate the curtain wall panels, filling the molds with the material. After curing and reinforcement processes, prefabricated curtain wall panels that meet the requirements are produced. Finally, according to the splicing method in the model, the prefabricated panels are positioned and connected, using overlapping and screw fixing methods, depending on the design and construction requirements.

[0004] When prefabricating and assembling curtain walls, due to the varying curvature of the outer surfaces, different sections of the curtain wall require auxiliary components for attachment and hoisting by workers. The lack of corresponding prefabricated splicing components necessitates manual angle adjustments during hoisting, making it impossible to promptly adapt to the different curvatures of the curtain walls. This results in the following adverse effects:

[0005] First, the lack of corresponding prefabricated splicing components may lead to incomplete curtain wall splicing, failing to achieve the expected design effect. This may result in discontinuous curtain wall appearance, obvious gaps or mismatches at the splicing points, and thus affect the overall aesthetics of the building.

[0006] Secondly, due to the lack of prefabricated splicing components that can adapt to different curvatures, workers need to manually adjust the direction and angle of the curtain wall, which may lead to unstable connections and loosening or deformation of the connection points between the curtain wall panels, thereby affecting the structural stability and durability of the curtain wall.

[0007] Third, because the direction and angle of the curtain wall need to be manually adjusted, and there is a lack of prefabricated splicing components that can be adapted to different curvatures, the construction process will be more complicated and time-consuming. Staff will need to spend more time and energy to adjust and adapt, which may lead to construction delays and increased construction costs.

[0008] Therefore, there is an urgent need to propose a prefabricated splicing device for irregular curved GRC curtain walls based on BIM technology. Summary of the Invention

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present invention provides a technical solution: a prefabricated splicing device for irregular curved GRC curtain walls based on BIM technology, including a curtain wall body 1 and a supporting main frame 2. An auxiliary overlapping component 3 is provided on the outer surface of the supporting main frame 2, and a supporting frame component 4 is also provided on the outer surface of the supporting main frame 2. The supporting main frame 2 is connected to a multi-angle coordinated adjustment component 5 through the supporting frame component 4. The multi-angle coordinated adjustment component 5 includes a middle supporting component 501 connected to the supporting frame component 4. The middle supporting component 501 includes a supporting straight rod 5011 slidably connected to the supporting frame component 4. An extension screw 5012 is provided at the rear end of the supporting straight rod 5011. A circular plate 5013 is connected to the supporting straight rod 5011 through the extension screw 5012. A top limiting component 502 is threadedly connected to the outer surface of the extension screw 5012. The top limiting component 502 includes a bearing plate threadedly connected to the outer surface of the extension screw 5012. The receiving collar 5021 has a side frame plate 5022 connected to its outer surface. A connecting rod 5023 is inserted into the outer surface of the side frame plate 5022. The side frame plate 5022 is connected to a limiting shaft plate 5024 through the connecting rod 5023. The receiving straight rod 5011 has a mating circular hole on its outer surface. The receiving straight rod 5011 is connected to a side end angle adjustment component 503 through the mating circular hole. The side end angle adjustment component 503 includes a connecting rod 5031 inserted into the inner surface of the mating circular hole. Both ends of the connecting rod 5031 are connected to an attachment ring plate 5032. A circular ring frame plate 5033 is fixedly connected to the outer surface of the attachment ring plate 5032. The receiving frame assembly 4 includes a receiving frame 401 connected to the outer surface of the receiving main frame 2. The outer surface of the receiving frame 401 has a four-sided through hole 402. The outer surface of the receiving straight rod 5011 is slidably connected to the inner surface of the four-sided through hole 402.

[0047] In this embodiment, if the multi-angle coordinated control component 5 is required for position adjustment and limiting, the expected adjustment position must first be confirmed. After confirmation, hold the circular plate 5013 and push the circular plate 5013 toward the expected adjustment position. During the pushing process, the receiving rod 5011 will slide on the inner surface of the four-sided through hole 402. Continue to push the circular plate 5013. After the receiving rod 5011 drives the adsorption component 6 to move to the expected adjustment position, the position adjustment process can be completed.

[0048] Example 2

[0049] like Figure 1 , Figure 2 , Figure 5and Figure 6 As shown, the front end of the receiving straight rod 5011 is connected to an adsorption component 6. The adsorption component 6 includes a fixed sleeve 601 fixedly connected to the front end of the receiving straight rod 5011. The front end of the fixed sleeve 601 is connected to a connecting frame plate 602. The outer surface of the connecting frame plate 602 is connected to a receiving support plate 603. The outer surface of the receiving support plate 603 is fixedly connected to a fixed long plate 604. The front surface of the fixed long plate 604 is provided with a vacuum suction cup 605. Multiple vacuum suction cups 605 are provided, and the multiple vacuum suction cups 605 are arranged in a matrix with the front surface of the fixed long plate 604 as the path. There are two receiving frame components 4, and both receiving frame components 4 are connected to the receiving main frame 2. There are two multi-angle coordinated control components 5, and the two multi-angle coordinated control components 5 correspond to the two receiving frame components 4 respectively. There are two adsorption components 6, and the two adsorption components 6 correspond to the two multi-angle coordinated control components 5 respectively.

[0050] In this embodiment, during the adsorption process, the vacuum suction cup 605 is first placed on the rear surface of the curtain wall body 1, ensuring that the vacuum suction cup 605 is in close contact with the rear surface of the curtain wall body 1 and completely covers the rear surface of the curtain wall body 1. Then, the vacuum supply source is turned on to generate sufficient vacuum pressure to adsorb the object. It should be noted that when the vacuum supply source is actually turned on, multiple vacuum suction cups 605 need to be adjusted. Then, the curtain wall body 1 is lifted using an indoor hoist, ensuring that multiple vacuum suction cups 605 remain in close contact with the rear surface of the curtain wall body 1. It should be noted that when moving the object, it is also necessary to ensure that the suction cups maintain continuous vacuum adsorption with the object surface.

[0051] Example 3

[0052] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, auxiliary positioning components 7 are provided on both sides of the outer surface of the main support frame 2. The auxiliary positioning components 7 include an electric push rod 701 provided on the outer surface of the main support frame 2. The output end of the electric push rod 701 is connected to a circular sleeve plate 702. A linkage shaft plate 703 is fixedly connected to the outer surface of the circular sleeve plate 702. A connecting short rod 704 is inserted into the outer surface of the linkage shaft plate 703. An extension support plate 705 is rotatably connected to the outer surface of the connecting short rod 704. A receiving short rod 706 is inserted into the outer surface of the extension support plate 705. A load-bearing ring plate 707 is provided at the front end of the receiving short rod 706. An auxiliary positioning frame 708 is provided on the outer surface of the load-bearing ring plate 707. A snap-fit ​​groove is opened on the outer surface of the auxiliary positioning frame 708.

[0053] In this embodiment, when using the auxiliary positioning component 7 for auxiliary positioning, it is first necessary to confirm the expected positioning angle and position. After confirmation, the auxiliary positioning component 7 can be used for overall adjustment. During the adjustment process, the electric push rod 701 needs to be turned on first. After the electric push rod 701 is turned on, its output end will drive the annular sleeve plate 702 to conduct, and the annular sleeve plate 702 will drive the linkage shaft plate 703 to move synchronously. It should be noted that during the adjustment of the electric push rod 701, the specific position of the auxiliary positioning frame 708 should be used as the adjustment reference. The electric push rod 701 should be continuously adjusted until the auxiliary positioning frame 708 moves to the expected position, at which point the adjustment can be stopped.

[0054] Example 4

[0055] like Figure 1 , Figure 2 and Figure 7 As shown, a fixing ring plate 301 is fixedly connected to the outer surface of the main support frame 2. A receiving sleeve plate 302 is fixedly connected to the outer surface of the fixing ring plate 301. An extension frame plate 303 is inserted into the inner surface of the receiving sleeve plate 302. Both ends of the extension frame plate 303 extend to the outside of the receiving sleeve plate 302. A positioning bolt 304 is inserted into the outer surface of the extension frame plate 303. There are two positioning bolts 304, and both positioning bolts 304 pass through the extension frame plate 303 and are connected to the outer surface of the main support frame 2. A short shaft 305 is fixedly connected to the outer surface of the receiving sleeve plate 302. A receiving ring groove is opened on the outer surface of the short shaft 305. The short shaft 305 is rotatably connected to a connecting shaft plate 306 through the receiving ring groove. An extension shaft plate 307 is connected to the outer surface of the connecting shaft plate 306. A docking plate 308 is fixedly connected to the outer surface of the extension shaft plate 307. Two docking holes are opened on the outer surface of the docking plate 308.

[0056] In this embodiment, during the actual overlapping process, in order to ensure the overall connection strength, the corresponding expansion screws are used to attach the lifting end of the indoor hoisting crane to the outer surface of the docking plate 308. After the attachment is completed, the expansion screws are aligned with the docking holes opened on the outer surface of the docking plate 308. Then, the two expansion screws are inserted and fixed. After the fixing is completed, the subsequent hoisting process can be carried out.

[0057] Working principle:

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in actual use, the entire component needs to be overlapped first. During the overlap process, the auxiliary overlap component 3 is used to assist the overlap. After the overlap is completed, the curtain wall body 1 to be connected is lifted by the construction crane to the expected connection position. After the movement is completed, the auxiliary positioning components 7 on both sides are used for auxiliary positioning. After the auxiliary positioning is completed, the adsorption component 6 is used for corresponding adsorption and fixation. During the adsorption and fixation process of the adsorption component 6, the multi-angle coordinated control component 5 and the support frame component 4 are used simultaneously to adjust the angle and position. After the adsorption components 6 on both sides have completed stable adsorption and fixation, the subsequent splicing process can be carried out.

[0059] At this time, the curtain wall body 1 will be in a three-point limiting state. First, the two sides of the curtain wall body 1 will be assisted in positioning by the auxiliary positioning components 7 on both sides. At the same time, the rear surface of the curtain wall body 1 will be simultaneously adsorbed and fixed by the two adsorption components 6. Then, the auxiliary crane after the overlap can be operated to carry out subsequent splicing and assembly. The curtain wall body 1 is placed at the splicing point, and the screws required for splicing are tightened with an electric drill. After the electric drill completes the tightening process, the splicing process of the current curtain wall body 1 can be completed.

[0060] The above content is only an overview of the working principle. The detailed workflow between each component will be introduced below:

[0061] First, during the actual overlapping process, in order to ensure the overall connection strength, the corresponding expansion bolts should be used to attach the lifting end of the indoor hoisting crane to the outer surface of the mating plate 308. After the attachment is completed, use the expansion bolts to align with the mating holes opened on the outer surface of the mating plate 308, and then insert the two expansion bolts for subsequent fixing. After the fixing is completed, subsequent hoisting can be carried out.

[0062] It should be noted that before the actual overlapping process, the other components in the auxiliary overlapping assembly 3 can be used to adjust the actual overlapping position. During the adjustment process, the connecting shaft plate 306 can be held directly and pushed in the expected adjustment direction. During the pushing process, the connecting shaft plate 306 will drive the extension shaft plate 307 to move. Similarly, the docking plate 308 connected to the extension shaft plate 307 will move along with it. The docking plate 308 is used as the position adjustment reference for subsequent pushing. After the docking plate 308 moves to the expected position, the pushing can be stopped.

[0063] It should be noted that after the overlapping process is completed, during the actual use of the indoor hoisting crane, the lifting end of the crane will drive the docking plate 308 to move, and the docking plate 308 will simultaneously drive the extension shaft plate 307 to move. Similarly, the extension shaft plate 307 drives the connecting shaft plate 306 to move, and the connecting shaft plate 306 will drive the short shaft 305 connected to it to move. At this time, the short shaft 305 will evenly distribute the transmitted force to the two positioning bolts 304, and the two positioning bolts 304 will then transmit the force to the extension frame plate 303. The extension frame plate 303 drives the receiving sleeve plate 302 and the fixing ring plate 301 to move, and the fixing ring plate 301 drives the main receiving frame 2 to move as a whole. The main receiving frame 2 as a whole drives the remaining components to move.

[0064] When using the auxiliary positioning component 7 for auxiliary positioning, it is first necessary to confirm the expected positioning angle and position. After confirmation, the auxiliary positioning component 7 can be used for overall adjustment. During the adjustment process, the electric push rod 701 needs to be turned on first. After the electric push rod 701 is turned on, its output end will drive the circular sleeve plate 702 to conduct, and the circular sleeve plate 702 will drive the linkage shaft plate 703 to move synchronously. It should be noted that during the adjustment of the electric push rod 701, the specific position of the auxiliary positioning frame 708 should be used as the adjustment reference. The electric push rod 701 should be continuously adjusted until the auxiliary positioning frame 708 moves to the expected position, and then the adjustment can be stopped.

[0065] After the position is moved, the angle can be adjusted. During the angle adjustment process, a wrench is used to hold the connecting short rod 704, and then the connecting short rod 704 is rotated toward the expected adjustment angle. During the rotation, the connecting short rod 704 will drive the extension support plate 705 to move, and the extension support plate 705 will drive the connected receiving short rod 706 and the load ring plate 707 to move. The auxiliary positioning frame 708 will also move along with it. After the auxiliary positioning frame 708 moves to the expected adjustment angle, the adjustment can be stopped.

[0066] After the angle adjustment is completed, the corresponding snap-fit ​​process is required. During the snap-fit ​​process, it is necessary to ensure that the auxiliary positioning frame 708 is located below both sides of the outer surface of the curtain wall body 1. After confirmation, the indoor hoisting crane is used for slow lowering. During the slow lowering process, the outer side of the curtain wall body 1 will gradually come into contact with the outer surface of the auxiliary positioning frame 708. During the contact process, the snap-fit ​​groove opened on the outer surface of the auxiliary positioning frame 708 will be close to the outer surface of the curtain wall body 1. After the outer surface of the curtain wall body 1 is completely attached to the inner surface of the snap-fit ​​groove, and after the crane operation is completed, the initial double-sided positioning process can be completed.

[0067] In subsequent use, if it is necessary to cancel the initial positioning process of the auxiliary positioning component 7, the electric push rod 701 must first be turned on. After the electric push rod 701 is turned on, its output end will drive the annular sleeve plate 702 to perform transmission, and the annular sleeve plate 702 will drive the linkage shaft plate 703 to perform synchronous transmission. The connecting short rod 704 and the extension support plate 705 connected to the linkage shaft plate 703 will move synchronously. Similarly, the supporting short rod 706 and the load-bearing ring plate 707 will move gradually, and the auxiliary positioning frame 708 will gradually move away from the outer surface of the curtain wall body 1. The output end of the electric push rod 701 is continuously adjusted until the locking groove of the auxiliary positioning frame 708 is completely disengaged from the outer surface of the curtain wall body 1, at which point the initial positioning process can be canceled.

[0068] When using the adsorption component 6 for adsorption and fixation, it is necessary to ensure that the outer surface of the vacuum suction cup 605 is intact. After confirming that the outer surface of the vacuum suction cup 605 is undamaged, check whether the connection pipe and pressure setting of the vacuum supply source are correct. After the above two checks are completed, the subsequent adsorption process can be carried out.

[0069] During the adsorption process, the vacuum suction cup 605 is first placed on the rear surface of the curtain wall body 1, ensuring that the vacuum suction cup 605 is in close contact with the rear surface of the curtain wall body 1 and completely covers the rear surface of the curtain wall body 1. Then, the vacuum supply source is turned on to generate sufficient vacuum pressure to adsorb the object. It should be noted that when the vacuum supply source is actually turned on, multiple vacuum suction cups 605 need to be adjusted. Then, the curtain wall body 1 is lifted using an indoor hoist, ensuring that multiple vacuum suction cups 605 remain in close contact with the rear surface of the curtain wall body 1. It should be noted that when moving the object, it is also necessary to ensure that the suction cups maintain continuous vacuum adsorption with the object surface.

[0070] In subsequent use, if it is necessary to cancel the adsorption fixation of the vacuum suction cup 605, first use the indoor hoist to place the curtain wall body 1 to the target position. Then, carefully control the position and orientation of the vacuum suction cup 605. When placing the object, gradually reduce the vacuum pressure so that the vacuum suction cup 605 gradually separates from the rear surface of the curtain wall body 1. After ensuring that the curtain wall body 1 is stably placed in the target position, turn off the vacuum supply source to cancel the adsorption fixation.

[0071] When using the multi-angle coordinated control component 5 to adjust the specific adsorption angle and position of the adsorption component 6, it is first necessary to confirm the expected control angle. After confirmation, the side angle control component 503 can be used for adjustment. First, hold the circular frame plate 5033, and then rotate the circular frame plate 5033 toward the expected control angle. During the rotation, the circular frame plate 5033 will drive the attachment ring plate 5032 to move. The connecting rod 5031 will also move synchronously with the attachment ring plate 5032. During the rotation of the connecting rod 5031, the receiving straight rod 5011 will be driven to adjust the angle. The receiving straight rod 5011 will adjust the angle on the inner surface of the four-sided through hole 402. It should be noted that during the angle adjustment process, the entire adsorption component 6 should be used as the angle adjustment reference. Continue to rotate the circular frame plate 5033 until the entire adsorption component 6 moves to the expected angle, and then stop the rotation.

[0072] If the multi-angle coordinated control component 5 is required for position adjustment and limiting, the expected adjustment position must first be confirmed. After confirmation, hold the circular plate 5013 and push it toward the expected adjustment position. During the pushing process, the receiving rod 5011 will slide on the inner surface of the four-sided through hole 402. Continue pushing the circular plate 5013 until the receiving rod 5011 moves the adsorption component 6 to the expected adjustment position. The position adjustment is then complete. After the position adjustment is completed, the corresponding limiting process needs to be performed. First, hold the side frame plate 5022, then rotate the side frame plate 5022 clockwise. During the clockwise rotation, the side frame plate 5022 will drive the connecting rod 5023 and the limiting shaft plate 5024 to transmit power. Continue to rotate the side frame plate 5022 until the limiting shaft plate 5024 is attached to the inner surface of the four-sided through hole 402. Then stop rotating. At this time, gradually press down the limiting shaft plate 5024. After the limiting shaft plate 5024 and the inner surface of the four-sided through hole 402 form a stable locking connection, the limiting process can be completed.
