Description

Technical Field

[0001] This utility model relates to the field of steel structure building monitoring technology, specifically a remote monitoring device for steel structure buildings based on BIM models. Background Technology

[0002] Steel structure buildings, using steel as the primary load-bearing structure, offer advantages such as high strength, light weight, and rapid construction. To ensure the safety and reliability of steel structure buildings, real-time monitoring is essential. Since steel structure buildings may be located in diverse geographical locations, some in remote or inaccessible areas, traditional manual periodic inspections are insufficient for timely problem detection. BIM (Building Information Modeling), a building information integration technology based on a three-dimensional digital model, integrates all information about the steel structure building, including its geometry, material properties, and component connections, into a single three-dimensional model. In terms of monitoring, by combining real-time collected data with the BIM model, intuitive three-dimensional visualization can be achieved.

[0003] Common BIM-based remote monitoring devices for steel structures first deploy monitoring sensors at key locations (such as beam-column joints and supporting structures). The signals collected by these sensors are then transmitted via cables to local data acquisition equipment. The pre-processed data is integrated with the BIM model, which contains detailed geometric information, component attributes, and connection relationships. Finally, based on data processing and analysis, the steel structure is monitored in real time. By setting thresholds, the system automatically issues an alert when parameters such as stress, displacement, or temperature of a component exceed a preset safety threshold, thus enabling remote monitoring.

[0004] However, this method, where the monitoring sensors are installed and fixed to the steel structure surface via corner brackets and bolts on both sides, results in short torque between connection points and a limited number of fixing points during continuous monitoring. This makes it difficult to accurately monitor the deformation of the steel structure and for the sensors to better follow the deformation, leading to large errors in the monitoring data and failing to meet the requirements for monitoring steel structure buildings. Therefore, a remote monitoring device for steel structure buildings based on a BIM model is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a remote monitoring device for steel structure buildings based on BIM models. This device solves the technical problem that the short torque between connection points and the limited number of fixed points make it difficult to accurately monitor the deformation of the steel structure, resulting in large errors in the monitoring data.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a remote monitoring device for steel structure buildings based on a BIM model, comprising:

[0009] The mounting head has a vibrating string inserted inside, and an electromagnetic induction coil is snapped onto the outside of the vibrating string.

[0010] The cable is connected to the outer side of the electromagnetic induction coil. Each mounting head has a snap-fit ​​socket welded to its top, and each snap-fit ​​socket has an insert plate inserted inside.

[0011] The main component is welded to the lower left and right sides of the mounting head. The outer ends of the insert plates all penetrate the corresponding positions of the snap-fit ​​bases, and the outer ends of the insert plates are all connected to screw connectors.

[0012] The screw is screwed into the inside of the rotary joint. The bottom end of the screw is fitted with a ball bearing. The bottom of the ball bearing is welded with a secondary angle bracket. Both the main angle bracket and the secondary angle bracket have through grooves inside.

[0013] Preferably, the inner cavity of the card holder and the insert plate are both trapezoidal in shape, and the bottom two sides of the insert plate are rounded.

[0014] Preferably, each screw has a knob coaxially mounted on its top end, and a limiting bolt is screwed into the inside of the insert plate, the length of which is greater than the thickness of the insert plate.

[0016] Preferably, the inner end of the fastening bolt penetrates the interior of the mounting head, and the length of the insert plate is greater than the length of the snap-fit ​​seat.

[0017] (III) Beneficial Effects

[0018] Compared with existing technologies, this utility model provides a remote monitoring device for steel structure buildings based on BIM models, which has the following advantages:

[0019] This BIM-based remote monitoring device for steel structures allows for adjustment of the extension length of the insert plate via an added locking bracket.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 The installation head 1 has a vibrating string 2 inserted inside, and an electromagnetic induction coil 3 is snapped onto the outside of the vibrating string 2.

[0027] Cable 4 is connected to the outer side of electromagnetic induction coil 3. A snap-fit ​​socket 5 is welded to the top of mounting head 1. Please refer to [link / reference]. Figure 3 Each card holder 5 has an insert plate 8 inserted inside;

[0028] Please see Figure 2 Main component code 6 is welded to the lower left and right sides of mounting head 1. Please refer to [link / reference]. Figure 3 The outer ends of the insert plate 8 all penetrate through the corresponding positions of the card holder 5, and the outer ends of the insert plate 8 are all connected to the screw connector 9.

[0029] The screw 10 is screwed into the inside of the rotary joint 9. A ball bearing 12 is fitted onto the bottom end of each screw 10. A secondary angle bracket 13 is welded to the bottom of each ball bearing 12. Both the main angle bracket 6 and the secondary angle bracket 13 have through slots 14 inside. The extension length of the insert plate 8 can be adjusted by adding a snap-fit ​​seat 5. Rotating the screw 10 causes the secondary angle bracket 13 to be pressed down. After the main angle bracket 6 is installed with screws, the extended and pressed-down secondary angle bracket 13 is then fixed, ensuring the firmness of the connection between the mounting head 1 and the steel structure. This allows the two sets of angle brackets to better follow the deformation of the steel structure when it deforms, enabling the electromagnetic... The induction coil 3 can more accurately measure the actual strain of the steel structure, thereby improving the monitoring accuracy. The inner cavity of the snap-fit ​​base 5 and the shape of the insert plate 8 are both trapezoidal. The bottom sides of the insert plate 8 are rounded. The top of the screw 10 is coaxially mounted with a knob 11. The insert plate 8 is screwed with a limit bolt 15. The length of the limit bolt 15 is greater than the thickness of the insert plate 8. The bottom of the main bracket 6 and the secondary bracket 13 are covered with rubber pads. The top side of the mounting head 1 is screwed with a fastening bolt 7. The inner end of the fastening bolt 7 penetrates the interior of the mounting head 1. The length of the insert plate 8 is greater than the length of the snap-fit ​​base 5.

[0030] This solution allows for adjustment of the extension length of the insert plate 8 via the added card holder 5. Then, by rotating the screw 10, the secondary angle bracket 13 is pressed down. After the main bracket 6 is installed with screws, the extended and pressed-down secondary angle bracket 13 is fixed, ensuring a firm connection between the mounting head 1 and the steel structure. This allows the two sets of angle brackets to better follow the deformation of the steel structure when it deforms, enabling the electromagnetic induction coil 3 to more accurately measure the actual strain of the steel structure, thereby improving monitoring accuracy.
