Description

A universal positioning connection device for steel structures based on BIM Technical Field

[0001] The present invention relates to the technical field of steel structure connection and positioning, and in particular to a universal positioning connection device for a steel structure based on BIM. Background Art

[0002] The oblique beam structure is a structure that combines the main beam with the oblique beam. This structure not only has unique stress characteristics, but also can enhance the overall spatial effect of the building. It has been widely used to enhance the aesthetics of the building and can adapt to the development of the times and the improvement of people's overall requirements for buildings.

[0003] When connecting the main beam and the oblique beam in an oblique beam, due to the large mass of the main beam and the oblique beam, direct welding is difficult and the accuracy is low. Therefore, in the existing technology, when connecting the main beam and the oblique beam, they are generally first fixed to the main beam through a positioning connecting plate, and then the oblique beam is fixed to the positioning connecting plate, thereby improving the connection accuracy and reducing the difficulty of connection. The specific operation is that the worker uses a T-square as a reference and welds by hand to position the connecting plate. However, due to the large error of manual operation, inaccurate positioning often occurs in actual use, which results in additional calibration after welding the positioning connecting plate, affecting construction quality and efficiency.

[0004] A Chinese patent with the authorization announcement number CN208056306U discloses a BIM-based steel structure oblique positioning connection device, which includes a main beam and an oblique beam. A base plate is provided on the main beam, and the left end of the top surface of the base plate is hingedly connected to a rotating plate via a rotating shaft. During use, the positioning angle between the main beam and the oblique beam is adjusted by manually rotating the rotating plate, which has high construction accuracy and reduces construction difficulty. However, when in use, the rotating plate can only rotate around its corresponding rotating shaft, so the angle that the positioning connection plate can rotate when in use is the same as that of the rotating plate, resulting in a limited angle and range of rotation of the positioning connection plate, which cannot better adapt to different working conditions and affects the use effect.

DETAILED DESCRIPTION

[0026] An embodiment of a BIM-based universal positioning connection device for steel structures is shown in Figures 1 to 14.

[0027] A BIM-based universal positioning and connection device for a steel structure includes a main beam 100, a first positioning member 200, a first rotating member 400, a first moving member 500, a second rotating member 600, and a positioning and connection plate 800; the cross-section of the main beam 100 is an I-shape, and the main beam 100 includes a web 120 and two wing plates 110, and the two wing plates 110 are respectively fixedly mounted on both sides of the web 120 and are symmetrically arranged about the center plane of the web 120.

[0028] The first positioning member 200 is detachably mounted on the flange 110. The first rotating member 400 includes a rotating frame 410. The rotating frame 410 is a U-shaped frame with its ends facing the main beam 100. The rotating frame 410 is rotatably mounted on the first positioning member 200. The two ends of the positioning connecting plate 800 are respectively mounted on the two ends of the rotating frame 410. When the rotating frame 410 rotates, the positioning connecting plate 800 can rotate about its vertical centerline. Initially, the positioning connecting plate 800 contacts and is perpendicular to the upper surface of the web 120.

[0029] A first slot 411 and a second slot 412 are respectively provided at both ends of the rotating frame. The first slot 411 is parallel to the second slot 412. The length direction of the first slot 411 is called the first direction. The initial direction of the first slot 411 is parallel to the setting direction of the two wing plates 110. The first movable member 500 can prompt the positioning connecting plate 800 to move along the first direction, thereby changing the position of the center line of the positioning connecting plate 800 on the main beam 100; the second rotating member 600 is installed at one end of the rotating frame 410 where the second slot 412 is provided. The second rotating member 600 can prompt the positioning connecting plate 800 to rotate around its horizontal center line, thereby changing the angle between the positioning connecting plate 800 and the web 120.

[0030] The rotating frame 410 includes an arc-shaped portion and two vertical portions. The arc-shaped portion is arranged toward the main beam 100, and the two vertical portions are respectively mounted at both ends of the arc-shaped portion. The two ends of the positioning connecting plate 800 are respectively mounted on the two vertical portions. The ends of the vertical portions away from the arc-shaped portion are the two ends of the rotating frame 410. The first rotating member 400 also includes a first servo motor 420. The first servo motor 420 is mounted on the first positioning member 200. The rotating frame 410 is mounted on the first servo motor 420. The middle position of the arc-shaped portion is mounted on the output shaft of the first servo motor 420 to drive the arc-shaped portion to rotate, thereby driving the rotating frame 410 to rotate. The first notch 411 and the second notch 412 are respectively opened on the two vertical portions.

[0031] The main beam 100, the first positioning member 200, the first rotating member 400, the first moving member 500, the second rotating member 600 and the positioning connecting plate 800 are first designed using BIM technology, then coordinated in the entire building model, and finally physically assembled. BIM (Building Information Modeling) technology is a digital tool used in engineering design, construction, and management. By integrating the digital and information models of buildings, they are shared and transmitted throughout the entire life cycle of project planning, operation, and maintenance, enabling engineering and technical personnel to correctly understand and efficiently respond to various building information, providing a basis for collaborative work for the design team and all construction entities including construction and operation units, and playing an important role in improving production efficiency, saving costs, and shortening construction periods.

[0032] Before use, first paste the BIM positioning sheet on the positioning connecting plate 800. The BIM positioning sheet carries the position and angle information. Then adjust according to the position and angle information carried on the BIM positioning sheet to find the welding point. When in use, if the positioning connecting plate 800 needs to be rotated around its own vertical axis, the first rotating member 400 is driven to make the first rotating member 400 drive the positioning connecting plate 800 to rotate around its own vertical axis to the required angle on the BIM positioning sheet. If the positioning connecting plate 800 needs to be moved relative to the rotating frame 410, the first moving member 5 is driven. 00 action, the first moving member 500 will move the positioning connecting plate 800 along the first direction, changing the position of the center line of the positioning connecting plate 800 on the main beam 100. If it is necessary to change the angle between the positioning connecting plate 800 and the web 120, the second rotating member 600 is driven to act, and the second rotating member 600 will rotate the positioning connecting plate 800 around its horizontal axis. After adjusting the angle and position information, the positioning connecting plate 800 and the web 120 are welded by mechanical welding, and then the positioning connecting plate 800 and the inclined beam are fixed.

[0033] By setting up the main beam 100, the first positioning member 200, the first rotating member 400, the first moving member 500, the second rotating member 600 and the positioning connecting plate 800, firstly, the positioning connecting plate 800 is adjusted respectively by the first rotating member 400 and the second rotating member 600, so that the angle change of the positioning connecting plate 800 can be adjusted. Secondly, the movement change of the positioning connecting plate 800 can be adjusted by the first moving member 500. In addition, the angle change and the movement change can be combined to change the angle and displacement of the positioning connecting plate 800, so that this embodiment can be adjusted according to the different position requirements of the positioning connecting plate 800, thereby improving the adaptability of the positioning connecting plate 800 under different working conditions, thereby improving the overall use effect.

[0034] The BIM-based universal positioning connection device for steel structures also includes a fixing sleeve 700 and a plurality of electromagnets 710. The fixing sleeve 700 is installed between the two vertical parts of the rotating frame 410. The fixing sleeve 700 is sleeved on the outside of the positioning connection plate 800. The electromagnet 710 is installed on the fixing sleeve 700. When the electromagnet 710 is energized, the fixing sleeve 700 can be locked with the positioning connection plate 800. When the electromagnet 710 is de-energized, the fixing sleeve 700 can be separated from the positioning connection plate 800.

[0035] The fixing sleeve 700 comprises a U-shaped portion 720 and two pivoting branches 730, each rotatably mounted on either end of the U-shaped portion 720. Together, the two pivoting branches 730 and the U-shaped portion 720 form a rectangular sleeve. During use, the positioning connecting plate 800 is first inserted into the fixing sleeve 700. Then, the electromagnet 710 is energized, engaging and locking the fixing sleeve 700 and the positioning connecting plate 800. Both the positioning connecting plate 800 and the fixing sleeve 700 are made of steel. To disassemble, the two pivoting branches 730 are rotated, opening the fixing sleeve 700 and allowing the positioning connecting plate 800 to be removed.

[0036] The first movable member 500 includes a first slider 520, a second servo motor 510 and a second gear 530. The first slider 520 is installed on the rotating frame 410. The base of the second servo motor 510 is installed on the first slider 520. The second gear 530 is installed on the output shaft of the second servo motor 510. The output shaft of the second servo motor 510 is rotatably matched with the fixed sleeve 700. A third rack 413 is provided in the first slot 411. The second gear 530 is installed in the first slot 411 and meshes with the third rack 413.

[0037] By setting the first slider 520, the second servo motor 510 and the second gear 530 to cooperate, when it is necessary to adjust the position of the center line of the positioning connecting plate 800 on the main beam 100, the second servo motor 510 is started, and the second servo motor 510 drives the second gear 530 to rotate. Since the third rack 413 inside the rotating frame 410 cannot move, the second gear 530 will move in the first slot 411 along the direction of the first slot 411, that is, move along the first direction, and then drive the positioning connecting plate 800 to slide along the first direction through the fixing sleeve 700.

[0038] The second rotating member 600 includes a second slider 620 and a third servo motor 610. The second slot 412 is arranged along the first direction. The second slider 620 is installed on the end of the rotating frame 410 where the second slot 412 is opened. The base of the third servo motor 610 is installed on the second slider 620. The fixing sleeve 700 is fixed on the output shaft of the third servo motor 610.

[0039] By setting the second slider 620 and the third servo motor 610 to cooperate, the third servo motor 610 can be driven to rotate, and the rotation of the third servo motor 610 drives the fixing sleeve 700 to rotate, and the rotation of the fixing sleeve 700 drives the positioning connecting plate 800 to rotate, thereby changing the angle between the positioning connecting plate 800 and the web 120, and further improving the angular rotation range of the positioning connecting plate 800.

[0040] The first positioning member 200 includes a first adjustment group 300, two claws 210 and two columns 220. Each claw 210 is slidably mounted on a flange 110 of the main beam 100. The columns 220 are arranged in a vertical direction and each column 220 is fixedly mounted on a claw 210.

[0041] The first adjustment group 300 includes a first rack 320 , a second rack 340 , a first gear 330 , a mounting housing 350 , and two fourth servo motors 310 . The two fourth servo motors 310 are respectively mounted on the two columns 220, the first rack 320 and the second rack 340 are both arranged in the horizontal direction and located above the rotating frame 410, one end of the first rack 320 and the second rack 340 are close to each other, and the other end is away from each other, and the ends of the first rack 320 and the second rack 340 away from each other are respectively mounted on the two fourth servo motors 310, the mounting shell 350 is mounted on the outside of the first rack 320 and the second rack 340, the gear shaft of the first gear 330 is mounted on the mounting shell 350, the first rack 320 and the second rack 340 are arranged face to face and are both engaged with the first gear 330, the two fourth servo motors 310 rotate in opposite directions, and when the two fourth servo motors 310 rotate, they can cause the first rack 320 and the second rack 340 to rotate around the first gear 330, thereby causing the first rack 320 and the second rack 340 to move away from or approach each other.

[0042] The fourth servo motor 310 is arranged in the vertical direction, and the output shafts of the two fourth servo motors 310 are respectively fixedly connected to the two columns 220. The first rack 320 and the second rack 340 have the same structure and are centrally symmetrically arranged about the first gear 330. The first rack 320 and the second rack 340 both include a rack portion and a mounting portion. The rack portion and the mounting portion are fixedly connected and are an integrally formed structure. The bases of the two fourth servo motors 310 are respectively fixedly mounted on the mounting portion of the first rack 320 and the mounting portion of the second rack 340. When the fourth servo motor 310 is started, since the output shaft of the fourth servo motor 310 is restricted by the column 220 and cannot rotate, the bases of the two fourth servo motors 310 will respectively drive the first rack 320 and the second rack 340 to rotate, thereby causing the first rack 320 and the second rack 340 to move away from or approach each other. Furthermore, a clamping block 360 is fixedly provided on one end of the rack portion of the first rack 320 away from its mounting portion and on one end of the rack portion of the second rack 340 away from its mounting portion. In the process where the bases of the two fourth servo motors 310 respectively drive the first rack 320 and the second rack 340 to rotate, thereby moving the first rack 320 and the second rack 340 away from each other, when the first rack 320 and the second rack 340 reach the first preset position, the mounting shell 350 will contact the clamping block 360 to limit the movement of the clamping block 360.

[0043] When the fourth servo motor 310 is started, the output shaft of the fourth servo motor 310 is restrained from rotating by the column 220. Therefore, the housings of the two fourth servo motors 310 respectively drive the first rack 320 and the second rack 340 to rotate about the first gear 330, thereby moving the first rack 320 and the second rack 340 away from each other. When the first rack 320 and the second rack 340 move away from each other until both the retaining blocks 360 contact the mounting housing 350, reaching the first predetermined position of the first rack 320 and the second rack 340, the mounting housing 350 restricts the movement of the retaining blocks 360, thereby restricting the movement of the first rack 320 and the second rack 340. The first servo motor 420 is mounted on the mounting housing 350.

[0044] By arranging the first rack 320, the second rack 340, the first gear 330, the two fourth servo motors 310, the two claws 210 and the two columns 220 to cooperate with each other, before driving the positioning connecting plate 800 to rotate around its own vertical axis, the two fourth servo motors 310 are first driven to rotate, and the two fourth servo motors 310 rotate in opposite directions, so that the first rack 320 and the second rack 340 move away from each other, and then the two claws 210 slide along the wing plate 110. When the rotation angle of the fourth servo motor 310 is 90°-α, the angle between the positioning connecting plate 800 and the wing plate 110 is α. Since the positioning connecting plate 800 is mounted on the mounting shell 350, the rotation of the fourth servo motor 310 will also drive the positioning connecting plate 800 to rotate synchronously by 90°-α. After the fourth servo motor 310 rotates to an angle of 90°-α, it reaches the first preset position of the first rack 320 and the second rack 340, and the fourth servo motor 310 stops rotating. Thereafter, if the positioning connecting plate 800 needs to continue rotating around its own vertical axis, the first servo motor 420 needs to be started. On the one hand, the first rack 320 and the second rack 340 are no longer perpendicular to the column 220 after rotation, so that when the positioning connecting plate 800 is welded, the welding process will not be affected by the restriction of the column 220, thereby facilitating the welding process. On the other hand, the rotation of the fourth servo motor 310 can also synchronously drive the positioning connecting plate 800 to rotate around its own vertical axis, reducing the amount of rotation of the positioning connecting plate 800 driven by the subsequent fourth servo motor 310. When the first rack 320 and the second rack 340 need to be brought closer to each other, the two fourth servo motors 310 are first driven to rotate, and the two fourth servo motors 310 are rotated in opposite directions. In particular, the rotation directions of the two fourth servo motors 310 at this time are opposite to the rotation directions of the two fourth servo motors 310 when the first rack 320 and the second rack 340 are driven to move away from each other. Therefore, when the two fourth servo motors 310 rotate, since the output shafts of the fourth servo motors 310 are restricted by the columns 220 and cannot rotate, the housings of the two fourth servo motors 310 will respectively drive the first rack 320 and the second rack 340 to rotate around the first gear 330, thereby bringing the first rack 320 and the second rack 340 closer to each other. At this time, the blocking blocks 360 on the first rack 320 and the second rack 340 will move away from each other, causing the first rack 320 and the second rack 340 to return to their original positions.

[0045] In combination with the above embodiments, the specific working principle and working process are as follows:

[0046] Before use, the two claws 210 are slidably installed on the positions marked on the two wing plates 110 respectively, and the BIM-based steel structure universal positioning connection device is slidably connected to the main beam 100 through the claws 210.

[0047] The positioning connecting plate 800 is then inserted into the inner side of the fixing sleeve 700. An external power source is then connected to energize the electromagnet 710, which locks the fixing sleeve 700 and the positioning connecting plate 800. The second servo motor 510 is then driven to align the positioning connecting plate 800 with the upper surface of the web 120, ensuring that the positioning connecting plate 800 is in contact and perpendicular to the upper surface. This completes the installation of the positioning connecting plate 800.

[0048] Before use, a BIM positioning sheet is attached to the positioning connecting plate 800. A positioning instrument with a suitable angle is used to determine the welding position and tilt angle of the positioning connecting plate 800. The BIM positioning sheet carries position and angle information, and adjustments are then made based on this information.

[0049] If the angle information carried by the BIM positioning piece needs to drive the positioning connecting plate 800 to rotate around its own vertical axis, then before driving the first servo motor 420 to rotate, in order to facilitate welding, the fourth servo motor 310 is first driven to rotate, and the two fourth servo motors 310 rotate in opposite directions. Since the output shaft of the fourth servo motor 310 is restricted by the column 220 and cannot rotate, the housings of the two fourth servo motors 310 will respectively drive the first rack 320 and the second rack 340 to rotate, thereby making the first rack 320 and the second rack 340 move away from each other. When the fourth servo motor 310 rotates 90°-α to the first preset position, the fourth servo motor 310 rotates 90°-α. Since the positioning connecting plate 800 is mounted on the mounting housing 350 via the rotating bracket 410, the rotation of the fourth servo motor 310 will also cause the positioning connecting plate 800 to rotate synchronously by 90°-α. Therefore, when the position and angle information carried by the BIM positioning piece is less than 90°-α, the angle of rotation of the positioning connecting plate 800 can be determined by simply driving the fourth servo motor 310 to rotate. After the fourth servo motor 310 rotates to the specified angle, the fourth servo motor 310 can be stopped. As shown in Figure 9, when the fourth servo motor 310 rotates 90°-α, the angle between the positioning connecting plate 800 and the wing plate 110 is α.

[0050] After the fourth servo motor 310 stops rotating, if the positioning connecting plate 800 needs to continue rotating around its own vertical axis, the first servo motor 420 needs to be started. The first servo motor 420 drives the rotating frame 410 to rotate, driving the positioning connecting plate 800 to rotate around its own vertical axis, as shown in Figure 10. At this time, the positioning connecting plate 800 continues to rotate β.

[0051] On this basis, if the vertical centerline position of the positioning connecting plate 800 needs to be adjusted, the second servo motor 510 is driven to rotate, which in turn drives the second gear 530 to rotate. Since the third rack 413 within the rotating frame 410 cannot move, the second gear 530 moves within the first notch 411, along the direction of the first notch 411, that is, along the first direction, thereby driving the two ends of the positioning connecting plate 800 to slide within the first notch 411 and the second notch 412, respectively, along the first direction. As shown in Figures 11 and 12, the distance c that the two ends of the positioning connecting plate 800 slide along the first direction within the first notch 411 and the second notch 412, respectively. At this time, the angle between the positioning connecting plate 800 and the web 120 is 90°.
