[0051] Further, the platform fixing device comprises:

[0052] A plurality of anchoring devices 4, a plurality of continuous beams 5 and screws;

[0053] The screws are used for fixing the first short pipe 21 and the second short pipe 22 through the plurality of adjusting holes 3, the plurality of continuous beams 5 are used for fixedly connecting the two telescopic cantilever square steels 2, and the plurality of anchoring devices 4 are used for anchoring on the structural floor of the main body structure.

[0054] Specifically, the telescopic cantilever square steel 2 extends through the reserved wall hole to the outside of the main structure, and the main structure refers to the circular conference room of the building. The inner part of the room is anchored to the structural floor of the main structure by multiple anchoring devices 4. The structural floor specifically refers to the plate between the two beams where the inner part of the room is located. The two telescopic cantilever square steels 2 are fixed and connected by several vertical fixed connecting beams 5, and a platform plate 6 is laid on the connecting beams 5. The top of the platform plate 6 is equipped with a fastener type steel pipe formwork support system, and all the support frame upright rods fall on the steel cantilever beam. Guardrails 7 are provided around the construction platform to ensure the safety of construction personnel.

[0055] Further, the steel wire rope 11 is connected with the lifting lug 12 at the top end of the central column 14 of the circular conference room, and the bottom end of the steel wire rope 11 is inserted into the two platform plates 6 through a steel drill.

[0056] Further, the sensor module 15 includes:

[0057] several pressure sensors, several displacement sensors, and several inclination sensors;

[0058] The several pressure sensors, several displacement sensors, and several inclination sensors are respectively arranged at the preset positions of the steel cantilever construction support platform 1 and the drag rod support column 8.

[0059] Based on finite element analysis or structural calculation, sensors are arranged in stress and strain concentration areas such as maximum bending moment and shear force. Preliminary plan is to preset pressure sensors at the connection between the steel cantilever square steel and the main structure of the building, and at the contact points between the bottom of the support column and the pulley, and between the top of the support column and the cantilever square steel. Displacement sensors are preset at the end of the cantilever square steel away from the main structure of the building, at the connection between the top of the support column and the cantilever square steel, at the middle of the column, at the mid-span area of the construction platform, and at the edge cantilever position. Inclination sensors are preset at the top, middle and bottom of the support column, arranged along the vertical axis of the column; at the top surface or side surface of the cantilever square steel, arranged along the length direction of the beam; and at the four corners or diagonal positions of the platform frame.

[0060] Specifically, a plurality of steel wire ropes 11 are arranged between the construction platform and the top end of the central column 14 of the building, and the top end of the steel wire rope 11 is connected with the lifting lug 12 at the top end of the central column 14 of the building (circular conference room), and the bottom end of the steel wire rope 11 is inserted into the construction platform panel through a steel drill. An independent counterweight bin 13 is arranged at the rear end of each side cantilever platform, and the counterweight blocks in the counterweight bin 13 are standard weight concrete blocks or iron blocks, which are convenient for combination and adjustment of weight. During construction, according to the load change and stress condition of the sensors on the construction platform, the independent counterweight bin 13 at the end of the platform is adjusted in real time, further enhancing the stability of the construction platform, and effectively resisting the influence of external loads such as wind force and construction vibration.

[0061] According to the stress characteristics of the structure, various sensors such as pressure sensors, displacement sensors, and inclination sensors are installed at key positions such as the construction platform and support columns 8. The data transmission lines of the sensors are tied to the surface of the components and led to a convenient place to reach and measure. Before and during the key construction conditions, data is collected using a portable data acquisition box. The data from the sensors is transmitted to the central control module 16, which simulates different load conditions of the construction support during construction according to a pre-set algorithm model. The stress conditions are analyzed to obtain the displacement, stress, and deformation parameter thresholds that can safely bear the construction load and the weight of the structure. The real-time data of displacement, stress, and deformation collected by the sensors, as well as the construction load format, are standardized and transmitted to the central control module 16. The model prediction results are compared with the actual monitoring data, and indicators such as mean square error and mean absolute error are calculated. If the error is within the allowed range and the data collected by the sensors is within the parameter threshold, the construction can be safely carried out. If the data exceeds the set threshold or the error exceeds the allowed range, the construction is suspended, the reasons are analyzed, and measures are taken. Manual control of the distance between the telescopic cantilever square steel 2 and the building can not only adapt to different lengths of the cantilever end during construction, but also control the counterweight by moving the independent counterweight bin 13 on the construction platform to maintain the balance and stability of the support. Then, the data is compared with the parameter threshold to observe whether the instability problem is solved. At the same time, the working state data of the construction support is transmitted to the remote monitoring center through a wireless network. Management personnel can view the operation of the construction support in real time through mobile phones, computers, and other terminal devices, realizing remote management and scheduling.

[0062] As shown in Figure 5 1. Construction preparation: synchronize the debugging of monitoring equipment and the debugging of the central control system to ensure the normal function of subsequent construction monitoring and system control, and make technical preparations for construction. After completing the debugging of monitoring equipment and the central control system, carry out site cleaning, material counting, personnel organization, and other construction preparation work.

[0063] 2. Set up the cantilever platform: two telescopic cantilever square steels extend to the outside of the main structure through the pre-embedded wall holes. The room part is anchored to the structural floor of the main structure using multiple anchoring devices. The two telescopic cantilever square steels are connected by several vertically fixed connecting beams, and a platform plate is laid on the connecting beams. Then, a counterweight bin is installed at the end of the cantilever.

[0064] 3. Install support columns: first, lay tracks around the support columns under the construction platform on the ground of the building, and at the same time, debug the column pulleys. After completion, install the support columns to cooperate with the tracks, pulleys, and other components to support the overall structure.

[0065] 4. Installing the cable: The steel wire rope lifting point and lifting lug are debugged to ensure the stability of the lifting point and the reliability of the lug connection. After debugging, the cable is installed, the top end of the steel wire rope is connected with the lug at the top of the central column of the building, and the bottom end is inserted into the construction platform panel through a steel drill to enhance the stability and rationality of the structure.

[0066] 5. Setting up the support: A fastener type steel pipe support system is set up on the top of the platform board. All support frame vertical rods are placed on the steel cantilever beam, and protective railings are provided around the construction platform to ensure the safety of construction personnel.

[0068] 7. Concrete pouring: After the template installation is accepted, concrete pouring is carried out. The concrete is poured into the template according to the construction process.
