Description
Technical Field
[0001] This application relates to the technical field of stress monitoring devices for steel structure module connection nodes, and in particular to a stress monitoring device for steel structure module connection nodes. Background Technology
[0002] In steel structure buildings, the stress state of the connection nodes of steel structure modules directly affects the safety and stability of the entire building structure. Traditional stress monitoring methods often suffer from low monitoring accuracy and complex operation, making it difficult to obtain stress information of connection nodes in real time and accurately.
[0003] Traditional torque monitoring tools lack coordinated design with displacement monitoring components. If displacement data is required, an additional independent displacement sensor must be installed, which not only increases equipment costs but may also cause asynchronous data acquisition due to improper sensor placement, affecting the accuracy of stress analysis.
[0004] Furthermore, the installation process of traditional monitoring devices is complex, requiring professionals to secure them with multiple bolts. This is not only time-consuming and labor-intensive, but also risks damaging the original stress state of the steel structure nodes due to improper installation. For the numerous connection nodes in large steel structure buildings, this inefficient installation method severely restricts the comprehensive implementation of monitoring work and makes it difficult to meet the needs of engineering safety assessments for large-scale, high-precision data collection. Utility Model Content
[0005] To achieve easy installation and accurate testing, this application provides a stress monitoring device for steel structure module connection nodes.
[0006] The stress monitoring device for steel structure module connection nodes provided in this application adopts the following technical solution:
[0007] A stress monitoring device for steel structure module connection nodes includes a torque testing component and a displacement testing component. The torque testing component includes a digital torque wrench, a horizontal bar connecting frame, and a vertical bar connecting frame. The horizontal bar connecting frame is inserted and fixed to the head of the horizontal bar connecting frame. The vertical bar connecting frame is arranged parallel to the bottom of the horizontal bar connecting frame and clamped and fixed to the lower end of the digital torque wrench. The displacement testing component includes a vertical bar clamping seat and a displacement sensor. The displacement sensor is horizontally mounted on the upper end face of the vertical bar clamping seat and is fixedly connected to the vertical bar clamping seat.
[0008] By adopting the above technical solution, the torque testing component is designed as a structure that combines a digital torque wrench, a horizontal bar connecting frame, and a vertical bar connecting frame. In actual use, the horizontal bar connecting frame is fixedly installed on the horizontal bar of the structural module, and then the vertical bar connecting frame is fixedly installed on the vertical bar of the structural module. The digital torque wrench connects the horizontal bar connecting frame and the vertical bar connecting frame together. In this way, when there is an angular displacement between the horizontal bar and the vertical bar of the steel structure module, it can be detected in time. By designing the displacement testing component as a structure that combines a vertical bar clamp and a displacement sensor, it is ensured that the displacement testing component is fixedly installed between the horizontal bar and the vertical bar of the steel structure module during use. The displacement sensor detects the positional changes of the vertical bar in real time, achieving dual monitoring through angle and displacement.
[0009] Optionally, the digital torque wrench includes a wrench handle and a wrench head for mounting on a crossbar connecting frame. The wrench head is rotatably mounted on the head of the wrench handle, and a digital display dial is fixedly mounted on the middle of the wrench handle.
[0010] By adopting the above technical solution, the digital display dial of the digital torque wrench can display the applied torque value in real time and intuitively. Operators can clearly and accurately obtain torque information, avoiding the errors that may occur when manually reading the scale in traditional torque wrenches, and greatly improving the accuracy of torque measurement. At the same time, the design of the wrench head rotating and mounted on the wrench handle head allows for flexible torque testing during use, enhancing the applicability and ease of operation of the device.

This connection method is convenient and quick to install, ensuring the connection stability between the crossbar connecting frame and the digital torque wrench. The center rod firmly connects the plug-in rod assembly and the crossbar flange, enabling the crossbar connecting frame to effectively transmit torque and ensuring the accuracy of torque testing. The crossbar flange can be easily connected to the crossbars of the steel structure module, enabling the monitoring of the torque at the crossbar connection nodes.
[0013] Optionally, the end of the plug-in rod assembly away from the central rod is provided with a magnetic suction post that attracts the wrench head, and the magnetic suction post engages and fixes with the plug-in rod assembly.
[0014] By adopting the above technical solution, the magnetic column adheres to the wrench head, further enhancing the connection strength between the connector assembly and the wrench head. This prevents the connector assembly from loosening or falling off during testing, thus improving the reliability of the device. The snap-fit fixing method makes the installation and removal of the magnetic column convenient, facilitating device maintenance and component replacement.
[0015] Optionally, the vertical rod connecting frame includes a clamping jaw, an extension rod, and a vertical rod flange. The clamping jaw is clamped and fixed to the tail of the wrench handle, and the extension rod is fixedly installed between the clamping jaw and the vertical rod flange.
[0016] By adopting the above technical solution, the grippers of the vertical rod connecting frame can firmly hold the end of the wrench handle, ensuring the relative position stability between the vertical rod connecting frame and the digital torque wrench. The extension rod allows the length of the vertical rod connecting frame to be adjusted according to actual needs, adapting to connection nodes of steel structure modules of different sizes and spacings. The vertical rod flange facilitates connection with the vertical rods of the steel structure module, enabling monitoring of the torque at the vertical rod connection node.

[0018] By adopting the above technical solution, the movable rod of the extension rod can slide within the housing, and the movable rod can be locked in the desired position by the locking bolt. This adjustable structural design allows the device to adapt to steel structure modules of different specifications, greatly improving the device's versatility. Operators can flexibly adjust the length of the extension rod according to actual conditions to ensure that the device can be accurately installed on the connection node, guaranteeing the accuracy of monitoring.
[0019] Optionally, the vertical rod clamping seat includes a concave shell and a clamping plate. There are two sets of clamping plates, and the two sets of clamping plates are symmetrically installed in the concave shell. The clamping plates are slidably connected to the concave shell, and a long screw is installed between the two sets of clamping plates.
[0020] By adopting the above technical solution, the two sets of gripper plates of the vertical rod clamping seat can achieve a firm grip on the vertical rod through the adjustment of the long screw, and can adapt to vertical rods of different diameters. This adjustable clamping structure makes the device more flexible and convenient during installation, and can be quickly and accurately fixed to the vertical rod. At the same time, the sliding connection between the gripper plates and the concave shell ensures smooth adjustment and improves installation efficiency.
[0021] Optionally, the upper end face of the concave shell is provided with a horizontal seat for mounting the displacement sensor. The horizontal seat is integrally formed with the concave shell, and the horizontal seat is fixedly connected to the displacement sensor by bolts.
