Description

Technical Field

[0001] This utility model relates to a monitoring device for building structure connection nodes based on BIM technology, belonging to the technical field of building BIM technology. Background Technology

[0002] BIM technology, or Building Information Modeling technology, is a comprehensive management system based on digital three-dimensional models. It integrates various building information and provides efficient management and decision support for the entire life cycle of building projects.

[0003] In the construction industry, structural connections are crucial for ensuring the overall stability and safety of buildings. These connections bear various loads, such as gravity loads, wind loads, and seismic loads, and their operational status directly affects the performance and service life of the building structure. Traditionally, monitoring of structural connections has relied primarily on periodic manual inspections.

[0004] Manual inspections have several limitations. Firstly, the inspection cycle is long, making it impossible to capture real-time changes in the status of connected nodes during use. During inspection intervals, connected nodes may have already suffered damage or performance degradation, but failure to detect this in time can lead to the accumulation of safety hazards and even serious safety accidents. Secondly, the accuracy of manual inspections is greatly affected by the experience and expertise of the inspectors; different personnel may produce different results, making it difficult to guarantee the reliability of monitoring.

[0005] Building Information Modeling (BIM) technology, as an advanced digital technology, has been widely applied in the construction industry. BIM models integrate various information about building projects, including geometric, physical, and construction information, providing a visual and collaborative platform for the design, construction, and operation management of building projects. However, because the monitoring of structural connection nodes mainly relies on periodic manual inspections, the information of corresponding connection nodes in the BIM model is only updated periodically during building operation, making real-time monitoring impossible. This results in operators finding it difficult to understand the actual working status of connection nodes through the BIM model in real time, thus hindering the full utilization of BIM technology in building safety management. Utility Model Content

[0006] In order to solve the above-mentioned problems in the existing technology, this utility model provides a monitoring device for building structure connection nodes based on BIM technology.

[0007] The technical solution of this utility model is as follows:

[0008] A monitoring device for building structure connection nodes based on BIM technology includes a detection component installed at the building connection node and a site data processing center set up on the construction site for building the BIM model. The detection component includes a first mounting plate and a second mounting plate, which are movably connected by a movable part to enable opening and closing. An angle sensor for detecting the rotation angle of the movable part is installed on the movable part. The first and second mounting plates are installed at the building connection node. Stress sensors are embedded on the outer walls of both the first and second mounting plates. The stress sensors on both sides abut against the corresponding side walls of the building connection node to detect the stress at the building connection node. Both the angle sensor and the stress sensor are communicatively connected to the site data processing center.

[0009] The movable component includes a first rotating shaft. A mounting groove is provided on the end of the first mounting plate that is close to the second mounting plate. The end of the second mounting plate that is close to the first mounting plate is located in the mounting groove. The first rotating shaft is also located in the mounting groove. Both ends of the first rotating shaft extend movably from the corresponding side wall of the mounting groove to the outer wall of the first mounting plate. The first rotating shaft is also fixedly installed through the corresponding side end of the second mounting plate.

[0010] The angle sensor includes a coil detection unit and a magnet sensing unit. The coil detection unit is fixedly disposed on one side of the outer wall of the first mounting plate, and the magnet sensing unit is fixedly disposed on one side of the end of the first rotating shaft. The coil detection unit and the magnet sensing unit are disposed on the same side and are coaxial with the first rotating shaft.

[0011] The monitoring device also includes a wireless communication module and a remote intelligent device. The on-site data processing center communicates with the remote intelligent device via the wireless communication module.

[0012] The first mounting plate and the second mounting plate are fixedly installed at the building connection nodes by means of self-tapping screws or adhesive.

[0013] The movable component includes a second rotating shaft. The ends of the first and second mounting plates that are close to each other are formed with L-shaped through grooves to form a receiving space for accommodating the second rotating shaft. The second rotating shaft is disposed in the receiving space. Both ends of the second rotating shaft move through the side wall of the corresponding L-shaped through groove to the outer wall of the first or second mounting plate at the corresponding position.

[0014] The angle sensor includes a detection end and a sensing end. The detection end is provided in the L-shaped through grooves on both sides, and the sensing end is symmetrically arranged on the shaft wall of the second rotating shaft. The detection ends on both sides detect the sensing ends at the corresponding positions.

[0015] The first mounting plate and the second mounting plate are each fixedly provided with a reset assembly. The reset assembly includes a reset housing, which is coaxial with the second rotating shaft. The end of the second rotating shaft is located inside the reset housing. The reset housing is also provided with a torsion spring structure, which connects the end of the second rotating shaft to the reset housing. When the torsion spring structures on both sides are in normal condition, the included angle between the first mounting plate and the second mounting plate is at least 180°.

[0016] The second rotating shaft is also fitted with a sleeve on its central shaft wall, and a hand-held part is provided on the sleeve wall.

[0017] This utility model has the following beneficial effects:

[0018] This invention involves installing detection components at building connection nodes. These components can detect stress and angle changes at the connection nodes in real time. Simultaneously, the detection components are connected to a field data processing center, allowing them to send the detected values. The field data processing center then updates the corresponding connection node information in its BIM model based on the received data. Operators can then promptly understand the actual working status of the connection nodes by viewing the numerical displays in the BIM model. This enables real-time monitoring of the connection nodes. Compared to existing technologies, this invention fully leverages the role of BIM technology in building safety management, provides superior monitoring results, and improves the reliability of building structures.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0041] Example 1: Please refer to Figures 1-4This embodiment provides a monitoring device for building structure connection nodes based on BIM technology, including a detection component 2 installed at the building connection node 1, a site data processing center 3 set up at the construction site for building the BIM model, a wireless communication module 4 electrically connected to the site data processing center 3, and a remote intelligent device 5 for use by construction personnel. The detection component 2 can detect stress changes and angle changes at the building connection node 1 in real time. The detection component 2 is communicatively connected to the site data processing center 3 so that it can send the detected corresponding values ​​to the site data processing center 3. The site data processing center 3 can update the information of the corresponding connection node in its BIM model in real time based on the received data. Operators can then understand the actual working status of the connection node in a timely manner by viewing the values ​​displayed in the BIM model. Meanwhile, the on-site data processing center 3 communicates with the remote intelligent device 5 via the wireless communication module 4. The on-site data processing center 3 can send the BIM model it has built to the remote intelligent device 5 via the wireless communication module 4. The remote intelligent device 5 can be a mobile phone, a dedicated tablet or other intelligent device for construction personnel to use. Construction personnel can use the remote intelligent device 5 to view the corresponding data in the BIM model to obtain the parameters of on-site construction, such as the parameters of the building connection node 1, so as to carry out related maintenance and repair work.

[0042] In this embodiment, the detection component 2 includes a first mounting plate 20 and a second mounting plate 21. The first mounting plate 20 and the second mounting plate 21 are movably connected by a movable part 22 to enable opening and closing. An angle sensor 23 for detecting the rotation angle of the movable part 22 is installed on the movable part 22. The first mounting plate 20 and the second mounting plate 21 are fixedly installed at the building connection node 1 by self-tapping screws or adhesive bonding, or other common fixing connection methods. Stress sensors 24 are embedded on the outer walls of both the first mounting plate 20 and the second mounting plate 21. When the first mounting plate 20 and the second mounting plate 21 are fixedly installed at the building connection node 1, the stress sensors 24 on both sides abut against the corresponding side walls of the building connection node 1 to detect the stress at the building connection node 1. Both the angle sensor 23 and the stress sensor 24 are communicatively connected to the field data processing center 3 to send the detected data to the field data processing center 3 for processing.

[0043] In this embodiment, the movable component 22 includes a first rotating shaft 200. A horizontally arranged mounting groove 201 is formed on the end of the first mounting plate 20 near the side of the second mounting plate 21. The end of the second mounting plate 21 near the side of the first mounting plate 20 is movably disposed within the mounting groove 201, ensuring that this end of the second mounting plate 21 does not interfere with the mounting groove 201 during opening and closing operations. The first rotating shaft 200 is horizontally disposed within the mounting groove 201, with both ends of the first rotating shaft 200 movably extending from the corresponding side wall of the mounting groove 201 to the outer wall of the first mounting plate 20. Furthermore, the first rotating shaft 200 is fixedly disposed through the corresponding side end of the second mounting plate 21. With the aforementioned configuration, the first rotating shaft 200 is movably connected to the first mounting plate 20 by extending through it, and is fixedly connected to the second mounting plate 21 by passing through it. During the opening and closing action, the first mounting plate 20 can move around the first rotating shaft 200, and the second mounting plate 21 can move accordingly by driving the rotation of the first rotating shaft 200. There is no movement interference between the two, thus allowing the required opening and closing action to be performed smoothly.

[0044] In this embodiment, the angle sensor 23 includes a coil detection unit 30 and a magnet sensing unit 31. The coil detection unit 30 is fixedly disposed on one side of the outer wall of the first mounting plate 20, and the magnet sensing unit 31 is fixedly disposed on one side of the end of the first rotating shaft 200. The coil detection unit 30 and the magnet sensing unit 31 are disposed on the same side and are coaxial with the first rotating shaft 200. When the first mounting plate 20 and the second mounting plate 21 are opened and closed, the coil detection unit 30 can detect the corresponding angle change value by sensing the cutting of the magnetic field lines by the magnet sensing unit 31. Meanwhile, since the coil detection unit 30 is fixedly mounted on the first mounting plate 20, it will perform corresponding actions as the first mounting plate 20 rotates. Even when the magnet sensing unit 31 does not move, it can still detect changes in the angle of the first mounting plate 20 by cutting magnetic field lines. Since the magnet sensing unit 31 is fixedly mounted on the first rotating shaft 200, it will perform corresponding actions as the first rotating shaft 200 rotates. Even when the coil sensing unit does not move, it can still cut magnetic field lines to achieve the required detection.

[0045] The working principle of this embodiment is as follows: During installation, the first mounting plate 20 and the second mounting plate 21 are installed to the building connection node 1 using self-tapping screws or adhesive bonding, ensuring that the stress sensors 24 on both sides are in contact with the corresponding sidewalls of the building connection node 1. Then, the on-site data processing center 3 is connected to the angle sensor 23 and the stress sensor 24 for communication, thus completing the installation. In use, the stress sensors 24 on both sides can detect stress changes at the building connection node 1 in real time, and the angle sensor 23 can monitor the angle changes between the first mounting plate 20 and the second mounting plate 21 in real time, thereby achieving real-time detection of angle changes at the building connection node 1. Both the stress sensors 24 and the angle sensor 23 can send the detected values ​​to the on-site data processing center 3 for processing. Based on the received data, the on-site data processing center 3 can update the information of the corresponding connection node in its constructed BIM model in real time. Operators can then understand the actual working status of the connection node by viewing the numerical displays in the BIM model, achieving real-time monitoring of the connection node.

[0046] The self-tapping screw or adhesive bonding method used to fix the monitoring device in Example 1 has certain problems. The self-tapping screw method may damage the structural strength of the building connection node 1, while the adhesive bonding method makes it difficult to remove the monitoring device from the building connection node 1 later. Therefore, based on Example 1, Example 2 is proposed.

[0047] Example 2: Please refer to Figure 5 and Figure 6This embodiment provides a monitoring device for building structure connection nodes based on BIM technology. The difference from Embodiment 1 is that the movable component 22 includes a second rotating shaft 202. L-shaped slots 203 are formed at the ends of the first mounting plate 20 and the second mounting plate 21 that are close to each other, creating a receiving space 204 for accommodating the second rotating shaft 202. The second rotating shaft 202 is horizontally positioned within the receiving space 204. Both ends of the second rotating shaft 202 extend movably from the sidewall of the corresponding L-shaped slot 203 to the outer wall of the corresponding first mounting plate 20 or second mounting plate 21. The angle sensor 23 includes a detection end 32 and a sensing end 33. The detection end 32 is provided in both L-shaped slots 203, and the sensing end 33 is symmetrically arranged on the shaft wall of the second rotating shaft 202. The detection ends 32 on both sides detect the sensing ends 33 at corresponding positions. With the aforementioned configuration, the second rotating shaft 202 is movably connected to both the first mounting plate 20 and the second mounting plate 21 by extending through them. Therefore, during the opening and closing action, both the first mounting plate 20 and the second mounting plate 21 can move around the second rotating shaft 202 without interfering with each other. When the first mounting plate 20 and the second mounting plate 21 open and close, they can drive the detection ends 32 on both sides to move relative to the sensing end 33, thereby enabling the detection of the required angle change.

[0048] Furthermore, in this embodiment, a reset assembly 6 is fixedly provided on the sidewalls of both the first mounting plate 20 and the second mounting plate 21. The reset assembly 6 includes a reset housing 61, which is coaxially arranged with the second rotating shaft 202. The corresponding side ends of the second rotating shaft 202 are all located inside the corresponding side reset housing 61. A torsion spring structure 62 is also provided inside the reset housing 61. The torsion spring structure 62 connects the end of the second rotating shaft 202 to the reset housing 61. When the torsion spring structures 62 on both sides are in normal condition, the included angle between the first mounting plate 20 and the second mounting plate 21 is at least 180°. With the aforementioned setup, most of the corners at common building connection nodes 1 are right angles, with a small portion being acute or obtuse angles. Therefore, when the first mounting plate 20 and the second mounting plate 21 are placed at the building connection node 1, both the first mounting plate 20 and the second mounting plate 21 need to rotate around the second pivot 202 to adapt to the corners at the building connection node 1, thus changing the angle. At this time, the torsion spring structures 62 on both sides will be torsion, thereby generating a restoring force for the first mounting plate 20 and the second mounting plate 21, allowing them to have an outward expansion tendency. Therefore, at this time, the first mounting plate 20 and the second mounting plate 21 will be fixed at the building connection node 1 under the action of the friction of the torsion spring structures 62 on both sides, without damaging the structural strength of the building connection node 1, and are easy to assemble and disassemble. When the detection component 2 is completely in contact with the building connection node 1, the first mounting plate 20 and the second mounting plate 21 will not pop outward from the building connection node 1 under the action of the torsion spring structures 62 on both sides due to the restriction of the non-flat angle of the structure of the building connection node 1.

[0049] In this embodiment, a sleeve 7 is fixedly fitted onto the middle shaft wall of the second rotating shaft 202, and a handle 8 is provided on the sleeve wall. The handle 8 allows the construction worker to grasp the handle 8 and send the detection component 2 to the building connection node 1. At this time, the first mounting plate 20 and the second mounting plate 21 rotate synchronously around the second rotating shaft 202 under the pressure of the corresponding side wall of the building connection node 1, so that the torsion spring structures 62 on both sides will be torsionally generated to restore force. Then the construction worker sends the detection component 2 completely into the building connection node 1, so that it fits into the building connection node, and the installation of the detection component 2 can be completed. The operation is simple.

[0050] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
