Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a prefabricated cantilever frame system. Background Technology

[0002] Traditional cantilever beams, with their steel sections extending into the interior, have a complex layout that hinders the removal of construction waste and movement of workers. Furthermore, the steel sections penetrating the walls can easily damage concrete beams and slabs, leading to floor leaks. Before dismantling traditional cantilever beams, it may be necessary to cut U-shaped anchor rings on-site, and afterwards, holes need to be filled and bricks replaced, increasing the construction period and posing serious safety hazards.

[0003] Chinese Patent Publication No. CN 111335618 A discloses a tying system for prefabricated suspended scaffolding, comprising several cantilever beams and scaffolding erected on the cantilever beams. Each cantilever beam is obliquely equipped with steel tie rods that connect the outer ends of the cantilever beams to the upper structural beams. The upper ends of the steel tie rods are connected to the upper structural beams via upper connecting components, and the lower ends are connected to the cantilever beams via lower connecting components. Turnbuckles are installed on the steel tie rods. It is evident that the tying system for this prefabricated suspended scaffolding has the following problem: the length of the cantilever structure cannot be adjusted according to actual conditions. Summary of the Invention

[0004] To address this issue, the present invention provides a prefabricated cantilever frame system to overcome the problem in the prior art that the length of the cantilever structure cannot be adjusted according to actual conditions.

[0005] To achieve the above objectives, the present invention provides a prefabricated cantilever frame system, comprising:

[0006] The load-bearing cantilever frame includes several horizontal bars and vertical bars fixed with through-wall bolts, as well as several diagonal braces for supporting the horizontal bars. Each horizontal bar and each diagonal brace has several pin holes, through which pins connect the horizontal bar and the diagonal brace. The load-bearing cantilever frame is fixed to the floor slab with the vertical bars by several through-wall bolts. Each through-wall bolt has a pressure sensor to detect the pressure borne by the through-wall bolt.

[0007] The unloading rope is connected to the pin hole on the horizontal bar of the load-bearing cantilever frame and is used for unloading the load-bearing cantilever frame. The unloading rope is fixed by a fixing device. The fixing device has a tension sensor and an adjustment device. The tension sensor detects the tension on the unloading rope in real time, and the adjustment device adjusts the length of the unloading rope.

[0008] The central control module is connected to pressure sensors, tension sensors, and adjustment devices. It analyzes real-time data detected by the sensors to determine whether adjustments need to be made to the prefabricated cantilever structure. This includes: determining whether a through-wall bolt needs adjustment based on its actual pressure value; calculating the overall status score of all through-wall bolts to determine their installation status; determining whether an unloading rope is in normal working condition based on its actual tension value; calculating the actual service life of the unloading rope to determine whether its foundation replacement cycle needs to be adjusted; determining whether to move the diagonal bracing of the load-bearing cantilever based on the status of the unloading rope; and reassessing the appropriateness of the installation and adjustment status when the horizontal bars of the load-bearing cantilever need to be adjusted.

[0009] Furthermore, for any through-wall bolt, when installing the pressure sensor, first reset the displayed value of the pressure sensor to zero, then tighten the through-wall bolt, record the displayed value of the pressure sensor at this time, and set it as the initial value. During use, the central control module detects and displays the actual pressure value of any through-wall bolt, and determines whether the through-wall bolt needs to be adjusted based on the actual pressure value of any through-wall bolt.

[0010] For any through-wall bolt

[0011] If the actual pressure value is less than the initial value, the through-wall bolt needs to be adjusted, and its usage time before the judgment should be recorded. The dangerous state of the through-wall bolt should be judged.

[0012] If the actual pressure value is greater than or equal to the initial value, record the usage time before the judgment and continue to judge the real-time pressure of the through-wall bolt.

[0013] Furthermore, the central control module calculates the overall status score of all through-wall bolts based on the actual pressure values ​​of all collected through-wall bolts, and determines the overall installation status of the through-wall bolts. The central control module has a status score threshold for the overall through-wall bolts and a pressure score parameter stored in the central control module. The pressure score parameter is proportional to the actual pressure value of the through-wall bolt.

[0014] If the overall through-wall bolt status score is greater than or equal to the status score threshold, the status is deemed unsafe, and the load-bearing cantilever frame needs to be unloaded and adjusted using unloading ropes.

[0015] If the overall through-wall bolt status score is less than the status score threshold, the status is determined to be safe, and the status determination of the overall through-wall bolts continues.

[0016] Furthermore, for any unloading rope, during installation, first set the value displayed by the tension sensor to zero, then bind the load-bearing cantilever frame to the unloading rope, and then use the adjustment device to adjust and tighten the unloading rope until the horizontal bar of the load-bearing cantilever frame is in a horizontal state. Record the value displayed by the tension sensor at this time and set it as the initial tension value. During use, the central control module detects and displays the actual tension value of any unloading rope, and determines whether the unloading rope is in normal working condition based on the actual tension value of any unloading rope.

[0017] The central control module has a first tension value and a second tension value for the unloading rope, and the second tension value is greater than the first tension value;

[0018] For any unloading rope

[0019] If the actual tension value is less than the first tension value, the adjusting device will adjust and tighten the unloading rope until the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value, at which point the tightening action of the unloading rope will stop.

[0020] If the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value, continue to determine the working status of the unloading rope;

[0021] If the actual tension value is greater than the second tension value, the unloading rope is in a dangerous state. Adjust the adjusting device to tighten other unloading ropes and install additional unloading ropes to unload the load.

[0022] Furthermore, for any unloading rope, the number of unloading adjustments and the usage time are recorded in the central control module when each unloading rope is adjusted. The actual usage cycle of the unloading rope is calculated in the central control module based on the number of unloading adjustments and the usage time of each unloading rope, and then the average usage cycle of the unloading rope is calculated.

[0023] If the average usage cycle is longer than the basic replacement cycle, then the basic replacement cycle should be shortened according to the actual usage cycle.

[0024] If the average usage cycle is equal to the basic replacement cycle, then the basic replacement cycle will not be adjusted.

[0025] If the average usage cycle is less than the basic replacement cycle, the basic replacement cycle shall be extended according to the actual usage cycle.

[0026] Furthermore, when calculating the actual service life of the unloading rope, the central control module stores the basic replacement cycle of the unloading rope, as well as the unloading adjustment coefficient and the service time coefficient. The unloading adjustment coefficient is proportional to the number of unloading adjustments, and the service time coefficient is proportional to the service time.

[0027] Furthermore, for load-bearing cantilever frames requiring unloading rope adjustment, if the unloading rope cannot be adjusted when changing it,

[0028] If the actual tension of the unloading rope cannot be adjusted to be greater than or equal to the first tension value and less than or equal to the second tension value, then according to the empty pin hole of the support rod, move the diagonal brace of the load-bearing cantilever frame to the inner position of the weighing cantilever frame, and readjust the unloading rope until the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value.

[0029] Furthermore, when the horizontal bar of the load-bearing cantilever frame needs to be adjusted, a pin is inserted through the pin hole to supplement the connection of the diagonal brace, making the horizontal bar cantilever structure more stable. At the same time, the central control module re-determines the overall status of the through-wall bolts and the working status of the unloading rope.

[0030] Furthermore, the fixing device can be directly fixed to the wall, and when the fixing device is directly fixed to the wall, the unloading rope is set at an angle;

[0031] When the unloading rope is set at an angle, when additional unloading ropes are installed for unloading, there is a maximum number of unloading ropes. When the maximum number of unloading ropes is insufficient for unloading, the diagonal brace of the load-bearing cantilever frame is moved to the inner position of the load-bearing cantilever frame, and the unloading rope is adjusted again until the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value.

[0032] Furthermore, the fixing device can also be fixed to the wall by a cantilever beam, and there are several fixing devices, in which case the unloading rope is set vertically;

[0033] When additional unloading ropes are installed at this time, there is a maximum number of unloading ropes. When the maximum number of unloading ropes is insufficient for unloading, the diagonal brace of the load-bearing cantilever frame is moved to the inner position of the weighing cantilever frame, and the unloading ropes are adjusted again until the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows: by changing the load-bearing cantilever frame in the prefabricated cantilever frame system to a prefabricated structure, the cantilever frame is easy to assemble and disassemble. At the same time, the addition of sensors to the prefabricated cantilever frame system makes structural changes after installation visible. The supplementary central control module analyzes the parts in the prefabricated cantilever frame system that are prone to safety risks, so that the operation during the adjustment process of the prefabricated cantilever frame system is supported by data. At the same time, it prevents structural problems from occurring in the system, facilitates the later maintenance and structural modification of the prefabricated cantilever frame system, and reduces maintenance costs in different usage environments.

[0035] Furthermore, this invention judges the actual pressure value of the through-wall bolts to represent the installation and fixing status of the load-bearing cantilever frame in the prefabricated cantilever frame system after construction is completed. At the same time, it analyzes and judges the data on the potential loosening of the through-wall bolts, reduces safety hazards during construction, and ensures that the prefabricated cantilever frame system is in a safe state after construction is completed, thereby ensuring the personal safety of workers.

[0036] Furthermore, this invention detects the tension of the unloading rope and visualizes the state of the unloading rope after installation using the values ​​detected by the tension sensor, ensuring that the unloading rope is stable after installation and enabling timely detection of safety hazards during the use of the prefabricated cantilever frame system.

[0037] Furthermore, by judging the basic replacement cycle of the unloading rope, the present invention adjusts the service life of the unloading rope in a timely manner to prevent the unloading rope from aging due to long service life, which could lead to construction accidents. At the same time, it ensures that the unloading rope is in normal working condition.

[0038] Furthermore, the present invention adjusts the position of the diagonal bracing of the load-bearing cantilever frame accordingly when the unloading rope cannot be unloaded, ensuring that the unloading rope and the load-bearing cantilever frame are installed in the appropriate positions.

[0039] Furthermore, by adjusting the length of the horizontal bar of the load-bearing cantilever frame when necessary, the central control module simultaneously re-determines the working status of the unloading rope and the through-wall bolts, ensuring that the prefabricated cantilever frame system can be properly adapted to different construction scenarios.

[0040] Furthermore, by setting the fixed position of the fixing device and further limiting the number of unloading ropes installed, the present invention ensures that the unloading of the load-bearing cantilever frame by the unloading ropes is within a certain range during the construction process, thereby reducing the wear and tear of the unloading ropes during their service life.

[0041] Furthermore, by setting the fixed position of the fixing device and further limiting the number of unloading ropes installed, the present invention ensures that the unloading ropes unload the load on the load-bearing cantilever frame during the construction process in accordance with the applicable range of unloading ropes. At the same time, the cantilever beam installation fixing device can also provide a work position for construction workers, increasing the application scenarios of the prefabricated cantilever frame system.

[0049] Please see Figure 1 As shown, Figure 1 This is a structural schematic diagram of the prefabricated cantilever frame system described in this embodiment.

[0050] This invention provides a prefabricated cantilever frame system, characterized in that it includes,

[0051] The load-bearing cantilever frame includes several horizontal bars and vertical bars fixed with through-wall bolts, as well as several diagonal braces for supporting the horizontal bars. Each horizontal bar and each diagonal brace has several pin holes, through which pins connect the horizontal bar and the diagonal brace. The load-bearing cantilever frame is fixed to the floor slab with several through-wall bolts. Each through-wall bolt has a pressure sensor 1, which detects the pressure borne by the through-wall bolt 2.

[0052] The unloading rope 5 is connected to the pin hole on the horizontal bar of the load-bearing cantilever frame and is used for unloading the load-bearing cantilever frame. The unloading rope is fixed by the fixing device 4. The fixing device 4 has a tension sensor 3 and an adjustment device. The tension sensor 3 detects the tension on the unloading rope in real time, and the adjustment device adjusts the length of the unloading rope.

[0053] The central control module is connected to pressure sensors, tension sensors, and adjustment devices. It analyzes real-time data detected by the sensors to determine whether adjustments need to be made to the prefabricated cantilever structure. This includes: determining whether a through-wall bolt needs adjustment based on its actual pressure value; calculating the overall status score of all through-wall bolts to determine their installation status; determining whether an unloading rope is in normal working condition based on its actual tension value; calculating the actual service life of the unloading rope to determine whether its foundation replacement cycle needs to be adjusted; determining whether to move the diagonal bracing of the load-bearing cantilever based on the status of the unloading rope; and reassessing the appropriateness of the installation and adjustment status when the horizontal bars of the load-bearing cantilever need to be adjusted.

[0054] This invention modifies the load-bearing cantilever frame in a prefabricated cantilever frame system into a prefabricated structure, making the cantilever frame easier to assemble and disassemble. Simultaneously, sensors are added to the prefabricated cantilever frame system to make structural changes after installation visible. A supplementary central control module analyzes components in the prefabricated cantilever frame system that are prone to safety risks, providing data support for operations during the adjustment process, preventing structural problems, facilitating later maintenance and structural modifications, and reducing maintenance costs under different operating environments.

[0055] Specifically, in this embodiment, for any through-wall bolt, when installing the pressure sensor, the value displayed by the pressure sensor is first set to zero, then the through-wall bolt is tightened, the value displayed by the pressure sensor at this time is recorded, and it is set as the initial value. During use, the central control module detects and displays the actual pressure value of any through-wall bolt, and determines whether the through-wall bolt needs to be adjusted based on the actual pressure value of any through-wall bolt.

[0056] For any through-wall bolt

[0057] If the actual pressure value is less than the initial value, the through-wall bolt needs to be adjusted, and its usage time before the judgment should be recorded. The dangerous state of the through-wall bolt should be judged.

[0058] If the actual pressure value is greater than or equal to the initial value, record the usage time before the judgment and continue to judge the real-time pressure of the through-wall bolt.

[0059] In this embodiment, the pressure sensor is set to an initial value of Y0.

[0060] If the actual pressure value Y1 is less than the initial value Y0, the through-wall bolt needs to be adjusted, and its usage time before the judgment is recorded. The dangerous state of the through-wall bolt is then determined. If the actual pressure value Y1 is greater than or equal to the initial value Y0, its usage time before the judgment is recorded, and the real-time pressure judgment of the through-wall bolt continues.

[0061] This invention determines the installation and fixation status of the load-bearing cantilever frame in the prefabricated cantilever frame system by judging the actual pressure value of the through-wall bolts. At the same time, it analyzes and judges the potential loosening of the through-wall bolts, reduces safety hazards during construction, and ensures that the prefabricated cantilever frame system is in a safe state after construction, thereby ensuring the personal safety of workers.

[0062] Specifically, in this embodiment, the central control module calculates the overall status score of all through-wall bolts based on the actual pressure values ​​of all collected through-wall bolts, and determines the overall installation status of the through-wall bolts. The central control module has a status score threshold for the overall through-wall bolts and a pressure score parameter stored in the central control module. The pressure score parameter is proportional to the actual pressure value of the through-wall bolt.

[0063] If the overall through-wall bolt status score is greater than or equal to the status score threshold, the status is deemed unsafe, and the load-bearing cantilever frame needs to be unloaded and adjusted using unloading ropes.

[0064] If the overall through-wall bolt status score is less than the status score threshold, the status is determined to be safe, and the status determination of the overall through-wall bolts continues.

[0065] In this embodiment, a prefabricated cantilever frame system contains a number of through-wall bolts Qi, i = 1, 2, 3, ..., n, where i is the serial number of the through-wall bolt.

[0066] Overall Through-Wall Bolt Status Rating : ;

[0067] in, The overall condition of through-wall bolts is scored;

[0068] i is the serial number of the through-wall bolt, i = 1, 2, 3, ..., n;

[0069] Yi represents the actual pressure value of the through-wall bolt with serial number i, in N.

[0070] yi is the pressure rating parameter for the through-wall bolt with serial number i. The pressure rating parameter yi is related to the actual pressure value Yi, and the larger the actual pressure value Yi, the larger the pressure rating parameter yi. The unit is 1. .

[0071] If the overall through-wall bolt status is rated Greater than or equal to the state score threshold If the condition is deemed unsafe, the unloading ropes need to be used to adjust the load-bearing cantilever frame; if the overall through-wall bolt condition score is... Less than the state score threshold If the condition is deemed safe, the status assessment of all through-wall bolts will continue.

[0072] This invention analyzes and scores the overall condition of through-wall bolts to determine their status and prepares for adjusting the unloading ropes. It also analyzes and judges the through-wall bolts fixed to the wall panel of the prefabricated cantilever frame system to ensure that the through-wall bolts are in a safe state, thus achieving overall state safety.

[0073] Specifically, in this embodiment, for any unloading rope, during installation, the value displayed by the tension sensor is first reset to zero, then the load-bearing cantilever frame is bound to the unloading rope, and then the adjustment device is used to adjust and tighten the unloading rope until the horizontal bar of the load-bearing cantilever frame is in a horizontal state. The value displayed by the tension sensor at this time is recorded and set as the initial tension value. During use, the central control module detects and displays the actual tension value of any unloading rope, and determines whether the unloading rope is in normal working condition based on the actual tension value of any unloading rope.

[0074] The central control module has a first tension value and a second tension value for the unloading rope, and the second tension value is greater than the first tension value;

[0075] For any unloading rope

[0076] If the actual tension value is less than the first tension value, the adjusting device will adjust and tighten the unloading rope until the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value, at which point the tightening action of the unloading rope will stop.

[0077] If the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value, continue to determine the working status of the unloading rope;

[0078] If the actual tension value is greater than the second tension value, the unloading rope is in a dangerous state. Adjust the adjusting device to tighten other unloading ropes and install additional unloading ropes to unload the load.

[0079] The central control module has a first tension value L1 and a second tension value L2 for the unloading rope, and the second tension value L2 is greater than the first tension value L1.

[0080] For any unloading rope Xj, j=1, 2, 3, ..., m, j is the sequence number of the unloading rope, and its actual tension value is L3.

[0081] If the actual tension value L3 is less than the first tension value L1, the adjusting device will adjust and tighten the unloading rope until the actual tension value is greater than or equal to the first tension value L1 and less than or equal to the second tension value L2, at which point the tightening action of the unloading rope will stop; if the actual tension value L3 is greater than or equal to the first tension value L1 and less than or equal to the second tension value L2, the working status of the unloading rope will continue to be judged; if the actual tension value L3 is greater than the second tension value L2, the unloading rope is in a dangerous state, and the adjusting device will adjust and tighten other unloading ropes, and additional unloading ropes will be installed to perform unloading.

[0082] This invention detects the tension of the unloading rope and visualizes its state after installation using the values ​​detected by the tension sensor. This ensures that the unloading rope is stable after installation and allows for the timely detection of safety hazards during the use of the prefabricated cantilever frame system.

[0083] Specifically, in this embodiment, for any unloading rope, the number of unloading adjustments and the usage time are recorded in the central control module when each unloading rope is adjusted. The actual usage cycle of the unloading rope is calculated in the central control module based on the number of unloading adjustments and the usage time of each unloading rope, and then the average usage cycle of the unloading rope is calculated.

[0084] If the average usage cycle is longer than the basic replacement cycle, then the basic replacement cycle should be shortened according to the actual usage cycle.

[0085] If the average usage cycle is equal to the basic replacement cycle, then the basic replacement cycle will not be adjusted.

[0086] If the average usage cycle is less than the basic replacement cycle, the basic replacement cycle shall be extended according to the actual usage cycle.

[0087] Specifically, in this embodiment, when calculating the actual service life of the unloading rope, the central control module stores the basic replacement cycle of the unloading rope, as well as the unloading adjustment coefficient and the service time coefficient. The unloading adjustment coefficient is proportional to the number of unloading adjustments, and the service time coefficient is proportional to the service time.

[0088] For any unloading rope Xj, the number of unloading adjustments Bj and the usage time Tj

[0089] Actual usage period Zj: ;

[0090] Wherein, Zj is the actual service life of the unloading rope with serial number j;

[0091] Bj represents the number of unloading adjustments made by the unloading rope with serial number j, in times.

[0092] bj is the unloading adjustment coefficient for the unloading rope with serial number j, and its unit is . The unloading adjustment coefficient bj is related to the number of unloading adjustments Bj, and the more unloading adjustments Bj there are, the larger the unloading adjustment coefficient bj is.

[0093] Tj represents the usage time of the unloading rope with serial number j, in hours (h).

[0094] tj is the usage time coefficient of the unloading rope with serial number j. It has no unit. The usage time coefficient tj is related to the usage time Tj, and the longer the usage time Tj, the larger the usage time coefficient tj.

[0095] Average usage cycle : ;

[0096] The average service life of the unloading rope in the prefabricated cantilever system;

[0097] j represents the total number of unloading ropes in the prefabricated cantilever system.

[0098] If the average usage cycle If the replacement cycle is greater than the basic replacement cycle Z0, then the average service life will be used. Shorten the basic replacement cycle Z0; if the average service life If the average usage cycle is equal to the basic replacement cycle Z0, then the basic replacement cycle Z0 will not be adjusted; if the average usage cycle is... If the replacement cycle is less than the basic replacement cycle Z0, then the basic replacement cycle Z0 will be extended according to the actual usage cycle.

[0099] This invention determines the basic replacement cycle of the unloading rope and adjusts its service life in a timely manner to prevent aging of the unloading rope due to long service life, which could lead to construction accidents. At the same time, it ensures that the unloading rope is in normal working condition.

[0100] Specifically, in this embodiment, when adjusting the unloading rope of the load-bearing cantilever frame, if the unloading rope cannot be adjusted when changing the adjustment rope,

[0101] If the actual tension of the unloading rope cannot be adjusted to be greater than or equal to the first tension value and less than or equal to the second tension value, then according to the empty pin hole of the support rod, move the diagonal brace of the load-bearing cantilever frame to the inner position of the weighing cantilever frame, and readjust the unloading rope until the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value.

[0102] This invention adjusts the position of the diagonal bracing of the load-bearing cantilever frame when the unloading rope cannot be unloaded, ensuring that the unloading rope and the load-bearing cantilever frame are installed in the appropriate positions.

[0103] Specifically, in this embodiment, when the horizontal bar of the load-bearing cantilever frame needs to be adjusted, a pin is inserted through the pin hole to connect a diagonal brace, making the horizontal bar cantilever structure more stable. At the same time, the central control module re-determines the overall status of the through-wall bolts and the working status of the unloading rope.

[0104] This invention ensures that the prefabricated cantilever frame system can be properly adapted to different construction scenarios by simultaneously re-determining the working status of the unloading rope and through-wall bolts when the length of the horizontal bar of the load-bearing cantilever frame needs to be adjusted.

[0105] Specifically, in this embodiment, the fixing device can be directly fixed to the wall, and when the fixing device is directly fixed to the wall, the unloading rope is set at an angle;

[0106] When the unloading rope is set at an angle, when additional unloading ropes are installed for unloading, there is a maximum number of unloading ropes. When the maximum number of unloading ropes is insufficient for unloading, the diagonal brace of the load-bearing cantilever frame is moved to the inner position of the load-bearing cantilever frame, and the unloading rope is adjusted again until the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value.

[0107] This invention sets the fixed position of the fixing device and further limits the number of unloading ropes installed, so that the unloading of the unloading ropes on the load-bearing cantilever frame is within a certain range during the construction process, thereby reducing the wear and tear of the unloading ropes during their service life.

[0108] Please see Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the prefabricated cantilever frame system fixing device in this embodiment, which is fixed by a cantilever beam.

[0109] Specifically, in this embodiment, the fixing device can also be fixed to the wall by a suspension beam, and there are several fixing devices. At this time, the unloading rope is set vertically.

[0110] When additional unloading ropes are installed at this time, there is a maximum number of unloading ropes. When the maximum number of unloading ropes is insufficient for unloading, the diagonal brace of the load-bearing cantilever frame is moved to the inner position of the weighing cantilever frame, and the unloading ropes are adjusted again until the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value.

[0111] This invention sets the fixed position of the fixing device and further limits the number of unloading ropes installed, so that the unloading ropes can unload the load on the load-bearing cantilever frame during the construction process in accordance with the applicable range of unloading ropes. At the same time, the cantilever beam installation fixing device can also provide a movement position for construction workers, increasing the application scenarios of the prefabricated cantilever frame system.

This includes: determining whether a through-wall bolt needs adjustment based on its actual pressure value; calculating the overall status score of all through-wall bolts to determine their installation status; determining whether an unloading rope is in normal working condition based on its actual tension value; calculating the actual service life of the unloading rope to determine whether its foundation replacement cycle needs to be adjusted; determining whether to move the diagonal bracing of the load-bearing cantilever based on the status of the unloading rope; and reassessing the appropriateness of the installation and adjustment status when the horizontal bars of the load-bearing cantilever need to be adjusted. For any unloading rope, the number of unloading adjustments and the usage time are recorded in the central control module when each unloading rope is adjusted. The actual usage cycle of the unloading rope is calculated in the central control module based on the number of unloading adjustments and the usage time of each unloading rope, and then the average usage cycle of the unloading rope is calculated. If the average usage cycle is longer than the basic replacement cycle, then the basic replacement cycle should be shortened according to the actual usage cycle. If the average usage cycle is equal to the basic replacement cycle, then the basic replacement cycle will not be adjusted. If the average usage cycle is less than the basic replacement cycle, the basic replacement cycle shall be extended according to the actual usage cycle.

2. The prefabricated cantilever frame system according to claim 1, characterized in that, For any through-wall bolt, when installing the pressure sensor, first reset the displayed value of the pressure sensor to zero, then tighten the through-wall bolt, record the displayed value of the pressure sensor at this time, and set it as the initial value. During use, the central control module detects and displays the actual pressure value of any through-wall bolt, and determines whether the through-wall bolt needs to be adjusted based on the actual pressure value of any through-wall bolt. For any through-wall bolt If the actual pressure value is less than the initial value, the through-wall bolt needs to be adjusted, and its usage time before the judgment should be recorded. The dangerous state of the through-wall bolt should be judged. If the actual pressure value is greater than or equal to the initial value, record the usage time before the judgment and continue to judge the real-time pressure of the through-wall bolt.

3. The prefabricated cantilever frame system according to claim 2, characterized in that, The central control module calculates the overall status score of all through-wall bolts based on the actual pressure values ​​of all collected through-wall bolts, and determines the overall installation status of the through-wall bolts. The central control module has a status score threshold for the overall through-wall bolts and a pressure score parameter stored in the central control module. The pressure score parameter is proportional to the actual pressure value of the through-wall bolt. If the overall through-wall bolt status score is greater than or equal to the status score threshold, the status is deemed unsafe, and the load-bearing cantilever frame needs to be unloaded and adjusted using unloading ropes. If the overall through-wall bolt status score is less than the status score threshold, the status is determined to be safe, and the status determination of the overall through-wall bolts continues.

The prefabricated cantilever frame system according to claim 3, characterized in that, For any unloading rope, during installation, first reset the value displayed by the tension sensor to zero, then bind the load-bearing cantilever frame to the unloading rope, and then use the adjustment device to adjust and tighten the unloading rope until the horizontal bar of the load-bearing cantilever frame is in a horizontal state. Record the value displayed by the tension sensor at this time and set it as the initial tension value. During use, the central control module detects and displays the actual tension value of any unloading rope, and determines whether the unloading rope is in normal working condition based on the actual tension value of any unloading rope. The central control module has a first tension value and a second tension value for the unloading rope, and the second tension value is greater than the first tension value; For any unloading rope If the actual tension value is less than the first tension value, the adjusting device will adjust and tighten the unloading rope until the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value, at which point the tightening action of the unloading rope will stop. If the actual tension value is greater than or equal to the first tension value and less than or equal to the second tension value, continue to determine the working status of the unloading rope; If the actual tension value is greater than the second tension value, the unloading rope is in a dangerous state. Adjust the tension of other unloading ropes using the adjustment device, and install other unloading ropes to unload the load.
