Description

Technical Field

[0001] This application relates to the technical field of construction safety, and in particular to a support monitoring device and method for an integral steel platform used in the construction of super high-rise buildings. Background Technology

[0002] With the increasing number of super high-rise buildings both domestically and internationally, integrated steel platforms play a crucial role in the construction process. These platforms offer numerous conveniences for super high-rise building construction, integrating personnel, machinery, materials, and even tower cranes onto their structure. Therefore, the safety and stability of these construction platforms are of paramount importance.

[0003] Currently, the most dangerous working condition in the construction of super high-rise buildings is the windy environment. In extremely harsh wind conditions, due to the high overall height of the construction platform, the wind force at the top of the construction platform far exceeds the wind speed at ground level. Although the structural formwork of the construction platform is very heavy, under extreme weather conditions, the steel structural components of the construction platform may still shift laterally or tilt due to the influence of surrounding wind loads. Furthermore, under frequent wind loads, the structural connection nodes of the columns on the overall steel platform are also prone to loosening, causing the entire construction platform to deform, thereby affecting the stability of the construction platform and making it difficult to guarantee the safety of construction. Summary of the Invention

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0018] This application discloses a support and monitoring device for an integral steel platform used in the construction of super high-rise buildings. (Refer to...) Figure 1 It includes a base 1 and a mounting frame 2. The base 1 is fixed to the ground by anchor piles, and the mounting frame 2 is fixed to the construction platform by bolts. A positioning frame 3 is provided on the base 1, and a positioning rod 4 is fixedly provided on the positioning frame 3.

[0019] Reference Figure 1 , 2 The base 1 is provided with a leveling mechanism for leveling the positioning frame 3. The leveling mechanism includes a limiting screw 11, a top column 12 and a drive assembly. The top wall of the base 1 is provided with multiple mounting slots 13 along the direction perpendicular to the top wall of the base 1. Each mounting slot 13 is fixedly provided with a limiting screw 11. The axial direction of the limiting screw 11 is perpendicular to the top wall of the base 1. The positioning frame 3 is provided with multiple mounting holes. The limiting screw 11 corresponds to the mounting hole one by one, and the limiting screw 11 passes through the corresponding mounting hole. The diameter of the mounting hole is larger than the diameter of the limiting screw 11. The limiting screw 11 is fitted with a limiting nut 111.

[0020] Reference Figure 2Each mounting slot 13 has a slidingly mounted top post 12, which is slidably fitted onto the limiting screw 11. The top of the top post 12 abuts against the bottom wall of the positioning frame 3. Each top post 12 corresponds to a set of drive components, which include a rack 14, a transmission gear 15, a worm gear 16, a worm 17, and a handle 18. The rack 14 is fixedly mounted on the corresponding top post 12, and the length of the rack 14 is parallel to the length of the top post 12. The base 1 has a groove corresponding to the mounting slot 13. The connected accommodating cavity has a transmission gear 15 rotatably mounted inside the cavity and meshing with a rack 14. A worm gear 16 is coaxially and fixedly connected to the transmission gear 15. A worm 17 is rotatably mounted inside the cavity and meshing with the worm gear 16. A rotating handle 18 is rotatably mounted on the base 1 and coaxially and fixedly connected to the worm 17. By rotating the rotating handle 18 corresponding to each top column 12, each top column 12 is driven to move up and down, thereby facilitating the leveling of the positioning frame 3 and keeping the positioning rod 4 vertical, making installation more convenient.

[0021] Reference Figure 1 , 3 The positioning rod 4 includes a first rod body 41 and a second rod body 42. One end of the first rod body 41 has a telescopic groove 411 along its length. The second rod body 42 is slidably disposed in the telescopic groove 411. The first rod body 41 is provided with a first fixing member 412 for preventing the second rod body 42 from sliding. The first fixing member 412 includes a first screw. The side wall of the first rod body 41 has a first threaded hole communicating with the telescopic groove 411 along its length perpendicular to the first rod body 41. The first threaded hole is adapted to the first screw and is inserted into the first threaded hole. The side wall of the second rod body 42 has a plurality of first insertion holes 421 for the first screw to be inserted. The plurality of first insertion holes 421 are arranged along the length of the second rod body 42.

[0022] Reference Figure 4 The positioning frame 3 is provided with a fixing component for fixing the first rod 41. The fixing component includes a fixing sleeve 31, a plug 32 and an elastic element 33. The fixing sleeve 31 is fixed on the positioning frame 3 and is adapted to the first rod 41. A fixing frame 34 is fixedly provided on the positioning frame 3. A sliding groove 341 is opened on the fixing frame 34 along the axial direction perpendicular to the fixing sleeve 31. A slider 342 is slidably arranged in the sliding groove 341. The slider 342 has a T-shaped cross section. The sliding groove 341 is adapted to the slider 342. The plug 32 is fixedly arranged on the slider 342. A through hole is opened on the side wall of the fixing sleeve 31. The plug 32 is slidably inserted into the through hole of the fixing sleeve 31. A insertion groove 413 for inserting the plug 32 is opened on the side wall of the first rod 41.

[0023] Reference Figure 4The elastic element 33 includes a compression spring, which is disposed in the slide groove 341. One end of the compression spring abuts against the side wall of the slide groove 341, and the other end of the compression spring abuts against the slider 342. The end of the insert block 32 near the fixed sleeve 31 has a guide slope. The guide slope gradually approaches the fixed frame 34 in the direction away from the positioning frame 3. The end of the first rod 41 away from the second rod 42 is inserted into the fixed sleeve 31. During the insertion of the first rod 41 into the solid sleeve, it interacts with the guide slope on the insert block 32. With the insertion of the first rod 41, the guide slope drives the insertion block 32 to slide away from the fixed sleeve 31, allowing the first rod 41 to be smoothly inserted into the fixed sleeve 31. When the insertion block 32 is aligned with the insertion groove 413 on the first rod 41, the insertion block 32 is inserted into the insertion groove 413 of the first rod 41 under the elastic force of the compression spring, thereby fixing the first rod 41 and detachably connecting the first rod 41 to the positioning frame 3 for convenient transportation.

[0024] Reference Figure 5 The mounting frame 2 has a guide groove 21, and a sliding frame 22 is slidably arranged in the guide groove 21. When the mounting frame 2 is fixed to the construction platform, the sliding direction of the sliding frame 22 is horizontal. A guide rod 221 is fixedly arranged on the sliding frame 22. The guide rod 221 is horizontally arranged and its length direction is perpendicular to the sliding direction of the sliding frame 22. A lateral displacement detection frame 23 is slidably sleeved on the guide rod 221. A lateral tilt detection frame 24 is hinged on the lateral displacement detection frame 23. The lateral tilt detection frame 24 is on the lateral displacement detection frame 23 through a ball joint. A connecting frame 25 is slidably arranged on the lateral tilt detection frame 24 in the vertical direction.

[0025] Reference Figure 5 The connecting frame 25 is provided with a connecting assembly for fixing the positioning rod 4. The connecting assembly includes a connecting sleeve 251 and a second fixing member 252. The connecting sleeve 251 is fixedly mounted on the connecting frame 25 and is adapted to the second rod body 42. The second fixing member 252 includes a second screw. The side wall of the connecting sleeve 251 is provided with a second threaded hole along the axial direction perpendicular to the connecting sleeve 251. The second threaded hole is adapted to the second screw. The second rod body 42 is provided with a second insertion hole 422 for the second screw to be inserted. The second rod body 42 is inserted into the connecting sleeve 251 and fixed by the second screw. When the connecting frame 25 is fixed to the second rod body 42, the second rod body 42 is kept vertical. After the connecting frame 25 is fixed to the second rod body 42, the sliding direction of the lateral tilt detection frame 24 is vertical.

[0026] Reference Figure 5Multiple positioning plates 26 are fixedly installed on the mounting frame 2 and around the lateral displacement detection frame 23. Multiple lateral pressure detection modules 231 are installed on the lateral displacement detection frame 23, and each lateral pressure detection module 231 corresponds to one of the positioning plates 26. The lateral pressure detection modules 231 are pressure sensors. An alarm device 27 is also installed on the mounting frame 2. In this application, the alarm device 27 is an audible and visual alarm. The lateral pressure detection modules 231 are electrically connected to the alarm device 27. When the construction platform shifts laterally, the lateral displacement detection frame 23 slides horizontally on the mounting frame 2. When the lateral pressure detection module 231 contacts the positioning plate 26, the lateral pressure detection module 231 detects a pressure signal and sends it back to the alarm device 27 to trigger an alarm.

[0027] Reference Figure 5 The lateral tilt detection frame 24 is equipped with a tilt angle detection module 241, which uses a tilt angle detector. The tilt angle detection module 241 is electrically connected to the alarm device 27. When the construction platform tilts or deforms, the tilt angle of the construction platform changes. At this time, the lateral displacement detection frame 23 slides on the mounting frame 2, and the lateral tilt detection frame 24 rotates relative to the lateral displacement detection frame 23. At the same time, the connecting frame 25 slides relative to the lateral tilt detection frame 24. The tilt of the construction platform is detected by the tilt angle detection module 241 and fed back to the alarm device 27 to trigger an alarm.

[0028] The implementation principle of a support monitoring device for an integrated steel platform for super high-rise construction according to an embodiment of this application is as follows: the base 1 is fixed to the ground by anchor piles, the first rod 41 of the positioning rod 4 is inserted into the fixed sleeve 31 on the positioning frame 3, the corresponding handle 18 of each top column 12 is rotated to drive each top column 12 to rise and fall, thereby facilitating the leveling of the positioning frame 3 and making the positioning rod 4 vertical. The mounting frame 2 is fixed to the construction platform by bolts, so that the sliding direction of the sliding frame 22 is horizontal. Then, the second rod 42 of the positioning rod 4 is inserted into the connecting sleeve 251, and the second rod 42 is fixed to the connecting sleeve 251 by the second screw, thereby fixing the connecting frame 25 to the second rod 42.

[0029] When the construction platform shifts laterally, the lateral displacement detection frame 23 slides horizontally on the mounting frame 2. When the lateral pressure detection module 231 contacts the positioning plate 26, the lateral pressure detection module 231 detects a pressure signal and sends it to the alarm device 27 for alarm. When the construction platform tilts or deforms, the lateral displacement detection frame 23 slides on the mounting frame 2, and the lateral tilt detection frame 24 rotates relative to the lateral displacement detection frame 23. At the same time, the connecting frame 25 slides relative to the lateral tilt detection frame 24. The tilt angle detection module 241 detects the tilt of the construction platform and sends it to the alarm device 27 for alarm. Thus, when the construction platform shifts laterally, tilts, or deforms, timely feedback and early warning can be given, allowing construction personnel to evacuate from the construction platform in time. It also facilitates timely maintenance by maintenance personnel, thereby effectively ensuring the safety of construction.

[0030] This application also discloses a monitoring method for a support monitoring device for an integral steel platform used in the construction of super high-rise buildings, comprising the following steps: S1. Fix the base 1 to the ground with anchor piles, insert the first rod 41 of the positioning rod 4 into the fixed sleeve 31 on the positioning frame 3, rotate the corresponding handle 18 of each top column 12 to drive each top column 12 up and down, so as to facilitate the leveling of the positioning frame 3 and make the positioning rod 4 vertical. Fix the mounting frame 2 to the construction platform with bolts to make the sliding direction of the sliding frame 22 horizontal. Then insert the second rod 42 of the positioning rod 4 into the connecting sleeve 251, and fix the second rod 42 and the connecting sleeve 251 with the second screw, so as to fix the connecting frame 25 and the second rod 42. S2. When the construction platform shifts laterally, the lateral displacement detection frame 23 slides horizontally on the mounting frame 2. When the lateral pressure detection module 231 contacts the positioning plate 26, the lateral pressure detection module 231 detects the pressure signal and sends it back to the alarm device 27 to trigger an alarm. S3. When the construction platform tilts or deforms, the lateral displacement detection frame 23 slides on the mounting frame 2, the lateral tilt detection frame 24 rotates relative to the lateral displacement detection frame 23, and at the same time, the connecting frame 25 slides relative to the lateral tilt detection frame 24. The tilt of the construction platform is detected by the tilt angle detection module 241 and fed back to the alarm device 27 to trigger an alarm.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
