Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel structure space frame construction measurement and early warning technology, and more specifically, it relates to a space frame measurement and early warning device in high-altitude and high-wind environments. Background Technology
[0002] In high-altitude and frigid regions, strong winds are common, and high wind speeds are prevalent. High altitudes are also accompanied by complex climatic conditions such as low temperatures and large temperature differences. In the field of steel space frame construction, these environmental factors have a significant impact on the construction process and project quality. The installation accuracy of steel space frames is crucial, as it directly relates to the safety and stability of the entire building structure. However, when installing steel space frame structures in high-altitude and frigid environments with strong winds, environmental factors can cause cumulative deviations during assembly. If these deviations are not effectively controlled, they will severely affect the installation accuracy, thereby threatening the quality and safety of subsequent projects.
[0003] While the overall hoisting method for steel space frames currently has certain advantages, traditional approaches have significant shortcomings during the lifting process. Traditional methods determine the lifting amount by recording data from hydraulic pressure sensors on the lifting machinery; however, this method cannot determine whether other factors affect the coordinates of the components, making it difficult to comprehensively and accurately grasp the actual state of the space frame structure during the lifting process. Furthermore, existing monitoring methods are insufficient for comprehensive, real-time, and precise monitoring of the space frame structure; they cannot promptly obtain crucial information such as the tilting deformation and displacement state of the space frame under dynamic and static loads.

[0030] Example 3:
[0031] As attached Figure 2 As shown, based on Embodiments 1 and 2, the measuring mechanism 4 further includes: a warning base 406, a control module 407, and a warning light 408. The warning base 406 is fixedly installed at the bottom of the measuring cylinder 402, the control module 407 is fixedly installed at the bottom of the warning base 406, and the control module 407 is electrically connected to the information acquisition and processing module 209.

[0032] The specific usage method of this embodiment is described below:
[0033] In this invention, the first mounting bracket 201 is movably placed at a suitable position on the outside of the steel structure frame 1. Then, the second mounting bracket 202 is rotated so that it also movably fits against the outside of the same member. The anti-slip pads 203 on the inner sides of the first and second mounting brackets 201 and 202 will fit tightly against the outside of the member, increasing friction and preventing the mounting structure 2 from sliding. The connecting bolts 206 are passed sequentially through the first connecting hole 204 on the first mounting bracket 201 and the second connecting hole 205 on the second mounting bracket 202. Locking nuts 207 are then tightened onto the outside of the connecting bolts 206 and adjusted to a suitable tightness, ensuring that the mounting structure 2 is firmly fixed to the member of the steel structure frame 1. This allows the measuring mechanism 4 and the connecting assembly 3 to be located between the two sets of members of the steel structure frame 1, thus easily fixing the device to various key parts of the steel structure frame 1. During the jacking process of the steel structure space frame 1, when the members of the steel structure space frame 1 tilt due to uneven force, the tilt angle of the steel structure space frame 1 and its members is collected in real time by the dual-axis tilt sensor 304. When the members of the steel structure space frame 1 displace due to uneven force, the displacement of the members of the steel structure space frame 1 drives the measuring rod 403 to slide inside the measuring cylinder 402 through the connecting component 3, causing the magnetic ring 405 to slide outside the waveguide wire of the magnetostrictive displacement sensor 404. This allows the magnetostrictive displacement sensor 404 to collect the displacement data of the members of the steel structure space frame 1 in real time. The dual-axis tilt sensor 304 and the magnetostrictive displacement sensor 404 transmit the tilt angle and displacement data to the information acquisition and processing module 209. The information acquisition and processing module 209 processes and analyzes the acquired data in real time, and transmits the processed data to an external monitoring device via the wireless communication module 2010. Simultaneously, the information acquisition and processing module 209 judges the data according to a preset safety threshold. When the data exceeds the safety threshold, it immediately sends a warning signal to the control module 407. Upon receiving the warning signal, the control module 407 immediately triggers the warning light 408 to flash, issuing an alarm signal. Upon seeing the flashing warning light 408, construction personnel should immediately stop the current construction operation, inspect and analyze the status of the space frame, identify the cause of the abnormality, and take corresponding measures to address it, such as adjusting the stress state of the space frame and reinforcing the space frame structure, to ensure the safety of the space frame. It should be noted that the above-mentioned warning method is existing technology.
