[0002] Building Information Modeling (BIM) is a building or building project information model composed of sufficient information to support new product development and management, and which can be directly interpreted by computer applications. In other words, it is the life cycle management of the built environment supported by digital technology. The core of BIM is to create a virtual three-dimensional model of the building project and use digital technology to provide this model with a complete building project information database that is consistent with the actual situation.

[0003] During the construction of steel structure buildings, it is sometimes necessary to weld inclined beams to the surface of the supporting beams. The inclined beams are suspended in the air and spliced ​​with the supporting beams. Problems such as mismatched tilt angles and misalignment often occur. Moreover, due to the large volume and weight of the steel inclined beams, it is difficult to align the welding positions between the two, which reduces the installation efficiency.

[0004] Therefore, it is necessary to provide a new BIM-based positioning device for steel structure buildings to solve the above problems. Utility Model Content

[0013] Compared with related technologies, the BIM-based steel structure building positioning device provided by this utility model has the following advantages:

[0014] This utility model provides a BIM-based steel structure building positioning device. During the construction of the steel inclined beam, when the steel inclined beam is hoisted to one side of the support beam, the hydraulic cylinder is connected to the fixed frame via the telescopic rod. The hydraulic cylinder operates to pull the bottom end of the steel inclined beam upwards, fixing the steel inclined beam to one side of the support beam and preventing it from swaying freely. The drive mechanism is then activated, delivering hydraulic oil into the fixed box, thereby pushing the piston and the extrusion plate to slide inside the fixed box. The extrusion plate moves into the fixed frame, pushing the steel inclined beam to move. The steel inclined beam slides along the support rod, allowing it to enter the two support plates. Then, the drive mechanism moves to retract the telescopic rod upward inside the hydraulic cylinder. At the same time, the hydraulic cylinder and the telescopic rod rotate, causing the telescopic rod to drive the steel inclined beam between the two support plates. When the first slide groove and the third slide groove are aligned, the support rod passes through the first slide groove and the third slide groove. The threaded sleeves at both ends of the support rod are rotated to fix the steel inclined beam between the two support plates, thus fixing one end of the steel inclined beam. Then, the drive mechanism is opened, and the drive mechanism drives the telescopic rod to extend, retract, and rotate, changing the angle and position of the steel inclined beam inside the support plate, so that the steel inclined beam can be accurately spliced ​​with the support beam, thereby facilitating welding between the two.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

Figure 3 for Figure 1 The diagram shows the structure of the fixing mechanism; Figure 4 for Figure 3 The diagram shows the internal structure of the fixed box.

Figure 7 for Figure 1 The diagram shows the splicing of the steel inclined beam; Figure 8 This is a schematic diagram of the circuit structure provided by this utility model. The BIM-based steel structure building positioning device includes: a hydraulic cylinder 5, which is rotatably connected to the side wall of a support beam 1, and a fixing mechanism 6 for adjusting the position of a steel inclined beam 2 is provided at the bottom end of the hydraulic cylinder 5; a support plate 3 is welded to the side wall of the support beam 1, and the surface of the support plate 3 is provided with a third groove 31; the side wall of the steel inclined beam 2 is provided with a first groove 21 and a second groove 22; when fixing the steel inclined beam 2, a support rod 63 is inserted through the steel inclined beam 2 and the support plate 3 or the fixing frame 61, and the threaded sleeve 64 is rotated on the side wall of the support rod 63, thereby fixing the steel inclined beam 2 to the side wall of the support plate 3 or the fixing frame 61.

[0026] The fixing mechanism 6 includes a fixing frame 61. Support rods 63 are slidably connected to the side walls of the fixing frame 61, the first slide groove 21, the second slide groove 22, and the third slide groove 31. Both ends of the support rods 63 are threadedly connected to threaded sleeves 64, and the threaded sleeves 64 abut against the side walls of the support plate 3 and the fixing frame 61. Fixing boxes 65 are symmetrically installed on the side walls of the fixing frame 61. A piston 67 and a pressing plate 66 are slidably connected inside the fixing box 65. The pressing plate 66 is fixedly connected to the piston 67. A sealing ring 68 is installed at the connection between the pressing plate 66 and the fixing box 65, and the pressing plate 66 abuts against the side wall of the steel inclined beam 2. The drive structure 4 delivers hydraulic oil into the interior of the fixed box 65, thereby pushing the piston 67 and the extrusion plate 66 to slide inside the fixed box 65. The extrusion plate 66 moves into the interior of the fixed frame 61, pushing the steel inclined beam 3 to move. The steel inclined beam 3 slides along the support rod 63, causing the steel inclined beam 2 to enter between the two support plates 3.

[0027] The support beam 1 has a welded support 52 on its side wall. A hydraulic cylinder 5 is rotatably connected inside the support 52, and a telescopic rod 51 is slidably connected inside the hydraulic cylinder 5. The fixed frame 61 has a rotatable connector 62 on its side wall, and the connector 62 is threadedly connected to the support 52. To facilitate rotation of the connector 62, the telescopic rod 51 is inserted into the connector 62, fixing it to the connector 62. The movement principle of the telescopic rod 51 inside the hydraulic cylinder 5 is the same as that of the extrusion plate 66. A piston is also slidably connected inside the hydraulic cylinder 5, and the piston is fixedly connected to the telescopic rod 51.

[0028] The hydraulic cylinder 5 and the fixed box 65 are both connected to the drive mechanism 4. A support frame 32 is installed at one end of the support plate 3. The drive mechanism 4 includes a storage cylinder 45 and a mounting box 46. The storage cylinder 45 and the mounting box 46 are placed on the surface of the support frame 32. A compression cylinder 49 is installed on the side wall of the mounting box 46. The compression cylinder 49 and the storage cylinder 45 are connected by a connecting pipe 44. A return oil pipe 41 and an inlet oil pipe 42 are installed at both ends of the hydraulic cylinder 5 and the fixed box 65. A solenoid valve 43 is installed on the side wall of both the return oil pipe 41 and the inlet oil pipe 42. The return oil pipe 41 is connected to... The storage cylinder 45 is connected to the oil inlet pipe 42, which is connected to the compression cylinder 49. A motor 48 is mounted on the side wall of the mounting box 46. A crank-connecting rod 47 is rotatably connected inside the mounting box 46, and the crank-connecting rod 47 is connected to the output shaft of the motor 48. A compression plug 411 is slidably connected inside the compression cylinder 49, and the compression plug 411 is rotatably connected to the crank-connecting rod 47. When the motor 48 operates, it drives the crank-connecting rod 47 to rotate continuously inside the mounting box 46, and the crank-connecting rod 47 drives the compression plug 411 to rotate within the compression cylinder 49. The compressor cylinder 49 rotates continuously. When the compression plug 411 moves towards the crank connecting rod 47, the one-way valve 7 inside the oil inlet pipe 42 closes, and the one-way valve 7 inside the connecting pipe 44 opens, allowing hydraulic oil from the storage cylinder 45 to enter the compressor cylinder 49 through the connecting pipe 44. When the compression plug 411 moves away from the crank connecting rod 47, the one-way valve 7 inside the oil inlet pipe 42 opens, and the one-way valve 7 inside the connecting pipe 44 closes, allowing hydraulic oil from the compressor cylinder 49 to enter the compressor cylinder 49 through the connecting pipe 44. The oil inlet pipe 42 enters the interior of the hydraulic cylinder 5 and the fixed box 65, thereby driving the telescopic rod 51 and the extrusion plate 66 to move. The hydraulic oil squeezed inside the hydraulic cylinder 5 and the fixed box 65 re-enters the interior of the storage cylinder 45 through the return oil pipe 41. The surface area of ​​one end of the compression plug 411 is smaller than the variable area of ​​one end of the piston 67 inside the hydraulic cylinder 5 and the fixed box 65. According to Pascal's principle, the compression plug 411 pushes the hydraulic oil into the hydraulic cylinder 5 and the fixed box 65 to drive the piston 67 to move, making it more labor-saving.

[0029] Both the connecting pipe 44 and the oil inlet pipe 42 are equipped with one-way valves 7. Each one-way valve 7 consists of a valve body 71, a retaining ball 72, and a stop lever 73. The valve body 71, which is funnel-shaped, engages the retaining ball 72, and the retaining ball 72 abuts against the stop lever 73. The one-way valves 7 inside the connecting pipe 44 and the oil inlet pipe 42 are installed in opposite directions. When hydraulic oil moves along the valve body 71 towards the stop lever 73, the hydraulic oil pushes the retaining ball 72 to abut against the stop lever 73, allowing the hydraulic oil to pass through the valve body 71. When hydraulic oil moves along the stop lever 73 towards the valve body 71, the hydraulic oil pushes the retaining ball 72 to engage the valve body 71, closing the valve body 71 and blocking the hydraulic oil from passing through. This ensures that the hydraulic oil can only flow in one direction inside the connecting pipe 44 and the oil inlet pipe 42.

[0030] Optical angle sensors 8 are installed on the side walls of the hydraulic cylinder 5 and the fixed frame 61, and distance sensors 9 are installed on the side walls of the support plate 3. The support frame 32 includes a central processing unit 410, which is electrically connected to the optical angle sensors 8, the solenoid valve 43, the BIM building model module, the distance sensors 9, and the motor 48. During the hoisting and alignment of the steel inclined beam 2, the information transmission module inside the central processing unit 410 is connected to the control display screen, allowing workers to access various information about the hoisting process of the steel inclined beam 2. When the steel inclined beam 2 moves towards the support plate 3, the distance sensors 9 installed on the side walls of the support plate 3 measure the distance between the steel inclined beam 2 and the support plate 3. The information is uploaded to the BIM building model module inside the central processing unit 410. The BIM building model module stores and records the three-dimensional model of this steel structure building project, and understands the splicing angle and splicing position between the support beam 1 and the steel inclined beam 2. Based on the information transmitted by the distance sensor 9, the BIM building model module calculates the position of the steel inclined beam 2 and determines whether the steel inclined beam 2 is located between the two support plates 3 and initially aligned with the welding position. When the steel inclined beam 2 is located between the support plates 3, the central processing unit 410 operates to open the motor 48 and the corresponding solenoid valve 43, allowing hydraulic oil to enter the interior of the hydraulic cylinder 5, causing the telescopic rod 51 to move upward and pull the bottom end of the steel inclined beam 2. The steel inclined beam 2 enters between the two support plates 3, and then the support rod 63 is used to fix it. One end of the steel inclined beam 2 is fixed between the two support plates 3. At this time, the optical angle sensor 8 operates, monitoring the angle between the hydraulic cylinder 5 and the support beam 1, and the angle between the fixed frame 51 and the steel inclined beam 2. Since the angle between the hydraulic cylinder 5 and the support beam 1, the angle between the fixed frame 51 and the steel inclined beam 2, and the angle between the steel inclined beam 2 and the support beam 1 add up to 180°, the BIM building model module determines the angle between the steel inclined beam 2 and the support beam 1 by understanding the angles at the other two locations. The central processing unit... The operation of motor 410 drives the operation of telescopic rod 51, changing the length and angle of the telescopic rod 51, thereby driving the steel inclined beam 2 to move between the support plate 2. When the BIM building model module determines that the angle between the steel inclined beam 2 and the support beam 1 is the welding angle, it indicates that the steel inclined beam 2 and the support beam 1 are accurately spliced. During the splicing process, the information received by the central processing unit 410 is uploaded to the control display screen through the information transmission module, so that the workers can understand the information during the hoisting process. The workers can also control the operation of the central processing unit 410 by operating the control display screen.

[0031] The working principle of the BIM-based steel structure building positioning device provided by this utility model is as follows: Before hoisting the steel inclined beam 2, the support rod 63 passes through the fixed frame 61 and the second sliding groove 22. The screw sleeve 64 is rotated on the side wall of the support rod 63 to fix the fixed frame 61 to the side wall of the steel inclined beam 2. At the same time, the support plate 3 and the support 52 are welded to the installation position on the surface of the support beam 1. The device is connected to an external power supply. When the steel inclined beam 2 is hoisted to one side of the support beam 1, the joint 62 is rotated to allow the telescopic rod 51 to enter the interior of the joint 62, so that the telescopic rod 51 is fixed together with the joint 62 (as shown in the attached figure). Figure 7 (As shown). When the central processing unit 410 is turned on, the electrical components operate. The distance sensor 9 measures the distance between the steel inclined beam 2 and the support plate 3, and simultaneously uploads the information to the BIM building model module inside the central processing unit 410. The BIM building model module stores and records the three-dimensional model of this steel structure building project, and understands the splicing angle and splicing position between the support beam 1 and the steel inclined beam 2. Based on the information transmitted by the distance sensor 9, the BIM building model module calculates the position of the steel inclined beam 2, and the central processing unit 410 turns on the motor 48 and the corresponding solenoid valve 43, and hydraulic oil is delivered into the interior of the fixed box 65, thereby pushing the piston 67 and the extrusion plate 66 to slide inside the fixed box 65. The extrusion plate 66 moves into the fixed box 65. The internal mechanism of the fixed frame 61 pushes the steel inclined beam 3 to move, and the steel inclined beam 3 slides along the support rod 63, so that the steel inclined beam 2 enters between the two support plates 3; when the BIM building model module determines that the steel inclined beam 2 is located between the support plates 3, the central processing unit 410 operates to open the motor 48 and the corresponding solenoid valve 43, so that hydraulic oil enters the interior of the hydraulic cylinder 5, causing the telescopic rod 51 to move upward and pull the bottom end of the steel inclined beam 2, so that the steel inclined beam 2 enters between the two support plates 3. When the first slide groove 21 is aligned with the third slide groove 31, the support rod 63 passes through the first slide groove 21 and the third slide groove 31, and the threaded sleeve 64 is rotated at both ends of the support rod 63, thereby fixing the steel inclined beam 2 between the two support plates 3 (as shown in the attached figure). Figure 1(As shown). The optical angle sensor 8 operates to monitor the angle between the hydraulic cylinder 5 and the support beam 1 and the angle between the fixed frame 51 and the steel inclined beam 2. Since the angle between the hydraulic cylinder 5 and the support beam 1, the angle between the fixed frame 51 and the steel inclined beam 2, and the angle between the steel inclined beam 2 and the support beam 1 add up to 180°, the BIM building model module determines the angle between the steel inclined beam 2 and the support beam 1 by knowing the angles of the other two positions. The central processing unit 410 operates to drive the motor 410 to operate, changing the length and angle of the telescopic rod 51, thereby driving the steel inclined beam 2 to move between the support plates 2. The steel inclined beam 2 drives the support rod 63 to slide inside the first slide groove 21 and the third slide groove 31, while the support rod 63 limits the movement of the steel inclined beam 2. When the BIM building model module determines that the angle between the steel inclined beam 2 and the support beam 1 is the welding angle, it indicates that the steel inclined beam 2 and the support beam 1 are accurately spliced ​​at this time. During the splicing process, the information received by the central processing unit 410 is uploaded to the control display screen through the information transmission module, so that the workers can understand the information during the hoisting process. The workers can also control the operation of the central processing unit 410 by operating the control display screen.
