Description

Technical Field

[0001] The present application relates to the field of structural construction monitoring, and in particular to a digital monitoring system and method for high-altitude Bailey frame construction. Background Art

[0002] The demand for structural design of high-altitude, large-span and large-space buildings is increasing. However, traditional high-altitude, large-span and large-space structures require the construction of corresponding tall formwork to support the corresponding structures.

[0003] In order to save construction space and improve the bearing capacity of the support system, the Bailey frame used in municipal construction is currently used in building construction projects. For example, a high-altitude construction method for a multi-story, large-span, heavy-loaded concrete structure with a publication number of CN109610834A.

[0004] Regarding the above-mentioned related technologies, in order to ensure the stability of the Bailey frame during the construction of the Bailey frame platform and the corresponding building structure construction, corresponding sensors will be set to monitor the displacement and stress of the Bailey frame in real time. However, only the structure of the Bailey frame itself is monitored accordingly. Once the stress or deformation of the supporting structure of the Bailey frame is too large, it will also have a great impact on the stability of the Bailey frame, making it difficult to warn of risks in time. Summary of the invention

[0005] In order to better provide timely warning of the risks of Bailey scaffolds, the present application provides a digital monitoring system and monitoring method for high-altitude Bailey scaffold construction.

[0006] In a first aspect, the present application provides a digital monitoring system for high-altitude Bailey frame construction that adopts the following technical solution.

[0007] A digital monitoring system for high-altitude Bailey frame construction includes a frame sensor module arranged on the Bailey frame to monitor the Bailey frame in real time, a support sensor module arranged on the Bailey frame support structure to monitor the Bailey frame support structure in real time, a data acquisition and processing module that collects and pre-processes data from the frame sensor module and the support sensor module, a data analysis module that analyzes the pre-processed data to determine whether corresponding indicators exceed limits, and an alarm module that alarms when the data exceeds limits.

[0008] By adopting the above technical solution, the Bailey frame support structure is monitored synchronously to conduct a more comprehensive monitoring of the stability of the Bailey frame, so as to provide a more timely warning of the risks that may exist in the Bailey frame.

[0009] Optionally, the Bailey frame support structure is a corbel installed on the shear wall, the corbel includes a web and a wing plate installed on the shear wall, the wing plate is fixedly connected to the web, the wing plate is used to support the end of the Bailey frame, and the support sensing module includes a stress sensor arranged on the web.

[0010] By adopting the above technical solution, the deadweight of the Bailey frame and the weight it carries are mainly transferred to the shear wall through the web, and the stress of the web is monitored to better provide timely warning when problems occur in the Bailey frame support structure.

[0011] Optionally, two webs are provided for one of the corbels, and both webs are provided with support sensing modules. The data analysis module analyzes the data output by the support sensing modules to determine the inclination of the Bailey frame.

[0012] Optionally, when the difference between the stress values ​​detected by the two supporting sensor modules of the same corbel exceeds a preset threshold, it indicates that the wing plate is deflected toward the supporting sensor module that detects a larger stress value.

[0013] By adopting the above technical solution, two supporting sensor modules are set for one corbel to prevent one supporting sensor module from having problems and failing to make a timely judgment. In addition, comparative analysis can be performed based on the data of the two supporting sensor modules of one corbel to obtain the inclination of the wing plate, so as to judge the inclination of the Bailey frame and issue a timely warning.

[0014] Optionally, two corbels are provided, and the Bailey frame support structure further includes an I-beam fixedly connected to the two corbels.

[0015] By adopting the above technical solution, it is inevitable that there will be deviations in the height of the fixed position of the corbel, and the I-beams are arranged so that the shelving elevations of the two ends of the Bailey frame tend to be consistent.

[0016] Optionally, when the difference between the stress values ​​detected by the support sensing modules of the two corbels is greater than a preset threshold, it indicates that the I-beam is tilted.

[0017] By adopting the above technical solution, whether the I-beam is in a horizontal state can be monitored in real time.

[0018] Optionally, the web is provided with plug posts at both ends corresponding to the supporting sensor module, the plug posts are inserted into the holes of the supporting sensor module, the plug posts are connected to a column rod, the column rod is threadedly connected to a mounting rod, the mounting rod is rotatably connected to a sticking rod, and the sticking rod and the column rod are located on opposite sides of the web in a one-to-one correspondence.

[0019] By adopting the above technical solution, it is possible to achieve a stable arrangement of the supporting sensor module without drilling holes on the web.

[0020] Optionally, the plug column is connected to the column rod by rotation around its own axis, and one end of the plug column inserted into the supporting sensor module is slidably connected with a tightening wedge block, and a pressure wedge block is slidably connected inside the plug column and abuts against the tightening wedge block to force the tightening wedge block away from the axis of the plug column. The plug column is coaxially connected to a middle rod threadedly connected to the pressure wedge block, and the plug column is provided with a reset spring for forcing the tightening wedge block to move toward the axis of the plug column.

[0021] By adopting the above technical solution, the two pressure wedge blocks are located at positions close to the two plug posts, so that when the web is compressed and deformed, the close plug posts enable the pressure wedge blocks to squeeze the support sensor module, so as to facilitate the insertion of the plug posts into the support sensor module while also ensuring that the support sensor module can effectively monitor the slight deformation of the web.

[0022] Optionally, the frame sensing module includes displacement sensors arranged at 1 / 4 and 1 / 2 of the span of the lower chord of the Bailey frame, and stress sensors arranged at the mid-span of the upper and lower chords of the Bailey frame.

[0023] By adopting the above technical solution, the deformation main positions and displacement conditions of each part of the Bailey frame can be monitored in real time.

[0024] In the second aspect, the present application provides a method for monitoring the construction of a high-altitude Bailey frame, which adopts the following technical solution.

[0025] A high-altitude Bailey frame construction monitoring method uses the above-mentioned high-altitude Bailey frame construction digital monitoring system and specifically includes the following steps.

[0026] Step 1: Use the frame sensing module to monitor the deformation and displacement of the Bailey frame as a whole in real time, and use the support sensing module to monitor the deformation and tilt of the Bailey frame support structure in real time; Step 2, the frame sensor module outputs the real-time data to the data acquisition and processing module for pre-processing; Step 3: The pre-processed data is transmitted to the data analysis module to determine whether the various indicators of the Bailey frame and the Bailey frame support structure exceed the limit; Step 4: When the index of the Bailey frame or the Bailey frame supporting structure exceeds the limit, the data analysis module outputs a signal to the alarm module for early warning.

[0027] By adopting the above technical solution, the stability of the Bailey frame can be monitored in real time in a more comprehensive manner.

[0028] In summary, the present application includes at least the following beneficial effects: The Bailey frame support structure is monitored synchronously to conduct a more comprehensive monitoring of the stability of the Bailey frame and to provide more timely warning of possible risks of the Bailey frame.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a digital monitoring system for high-altitude Bailey frame construction, referring to Figure 1 , including a frame sensor module 1 arranged on the Bailey frame, a support sensor module 2 arranged on the Bailey frame support structure, a data acquisition and processing module 3, a data analysis module 4 and an alarm module 5. The frame sensor module 1 and the support sensor module 2 transmit the real-time monitoring data to the data acquisition and processing module 3, and the data acquisition and processing module 3 performs pre-processing such as analog-to-digital conversion, amplification and filtering on the data. The pre-processed data is transmitted to the data analysis module 4 to determine whether various indicators are out of limit according to the preset safety threshold. When an indicator exceeds the limit, the alarm module 5 alarms to remind the staff to check the Bailey frame or the Bailey frame support structure in time.

[0033] The frame sensing module 1 can be a displacement sensor disposed at the 1 / 4 and 1 / 2 mid-span of the lower chord of the Bailey frame and a stress sensor disposed at the mid-span of the upper and lower chords of the Bailey frame. The support sensing module 2 can be a stress sensor disposed at the Bailey frame support mechanism.

[0034] Reference Figure 2 The Bailey frame support structure includes two brackets 51 and an I-beam 54. The heights of the two brackets 51 are as close as possible. The I-beam 54 is placed on the two brackets 51, and a steel sheet is welded on the lower bracket 51 to ensure that the I-beam 54 is horizontal. One end of the Bailey frame is placed on the three-story structure floor and the other end is placed on the I-beam 54. The I-beam 54 of the corresponding height is selected according to the elevation of the three-story structure floor to ensure that the elevations of the two ends of the Bailey frame are consistent. And the I-beam 54 can be doubled according to needs to improve the bearing capacity.

[0035] Reference Figure 2, each corbel 51 includes two webs 52 and a wing 53, and a pre-embedded steel member is set on the shear wall of the corbel to weld the webs 52 and the wing 53 to the corresponding pre-embedded steel members. The wing 53 is horizontally welded to the upper surface of the two webs 52. Support sensor modules 2 are set at the opposite ends of the two webs 52 of the same corbel 51, and the length direction of the support sensor module 2 is set to the direction of the connection line between the bottom of the web 52 and the two ends of the wing 53 away from the pre-embedded steel member, so as to accurately monitor the deformation caused by the compression of the web 52. At the same time, when the difference in stress detected by the two support sensor modules 2 of the same corbel 51 is greater than the preset safety threshold, it indicates that the wing 53 of the corresponding corbel 51 is tilted, and the alarm module 5 is operated. In addition, when the difference in stress detected by the support sensor modules 2 of the two corbels 51 corresponding to the same I-beam 54 is greater than the preset safety threshold, it indicates that the corresponding I-beam 54 is tilted, and the alarm module 5 is operated.

[0036] Reference Figure 2 and Figure 3 , each web 52 can be closely attached to the surface of the supporting sensor module 2 with two sticking rods 58, and the ends of the two sticking rods 58 away from the web 52 are both rotatably connected to the mounting rods 57, and the length direction of the mounting rods 57 is consistent with the thickness direction of the web 52, and the two mounting rods 57 are both threadedly connected to the column 56, and the two sticking rods 58 are provided with one end of the mounting rods 57 fixedly connected to the guide rod 44, and the guide rod 44 is penetrated along the length direction of the mounting rod 57 and slidably connected to the column 56, and the mounting rod 57 is threadedly connected to the fastening nut 45 that can be pressed against the side of the column 56 away from the sticking rod 58. The ends of the two column 56 away from the mounting rod 57 are both rotatably connected to the plug posts 55, and the rotation axis direction of the plug posts 55 is consistent with the length direction of the mounting rod 57, and the two plug posts 55 are plugged into the two holes of the supporting sensor module 2 one by one.

[0037] Reference Figure 3 The two plug posts 55 are both slidably connected with the tight wedges 59 that can be exposed to the outside along their radial direction. The plug posts 55 are slidably connected with the pressure wedges 41 along their axial direction. The inclined surface of the pressure wedges 41 abuts against the inclined surface of the tight wedges 59. The end of the pressure wedges 41 away from the tight wedges 59 is threadedly connected with the middle rod 42. The length direction of the middle rod 42 is consistent with the axial direction of the plug posts 55. The middle rod 42 is rotatably connected to the plug posts 55, and one end of the middle rod 42 is exposed to the end surface of the plug posts 55 away from the web 52. The plug posts 55 are provided with a return spring 43 that can force the tight wedges 59 to move toward the axis of the plug posts 55.

[0038] When the support sensor module 2 is fitted to the belly plate 52 for installation, first insert the plug post 55 into the hole corresponding to the support sensor module 2, then rotate the installation rod 57 so that the plug post 55 and the sticking rod 58 are initially tightly attached to the belly plate 52, then rotate the plug post 55 so that the two tightening wedges 59 are located close to the two plug posts 55, and then rotate the middle rod 42 so that the two tightening wedges 59 are close to each other and pressed against the inner wall of the hole of the support sensor module 2 until the support sensor module 2 can detect the change in stress, then rotate and tighten the installation rod 57, and then rotate the fastening nut 45 to fit tightly against the column rod 56 to complete the installation and fixation of the support sensor module 2.

[0039] The implementation principle of a digital monitoring system for high-altitude Bailey frame construction in an embodiment of the present application is to monitor the stress of the web 52 to better ensure the overall stability of the Bailey frame and to provide timely warnings for existing risks.
