Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] The inventors discovered that high-altitude, large-span cantilever structures cannot be constructed on attached lifting scaffolding. At the same time, conventional cantilevered I-beam type operating platforms cannot meet the load requirements of large-span cantilever structures.

[0049] Based on this, the present invention provides a steel platform system suitable for formwork support of super high-rise, high-span, large-span cantilever structures, referring to... Figure 1 and Figure 2 As shown, it includes a steel platform body 1, several tie rods 2 and several support rods 3;

[0050] The steel platform body 1 includes several cantilevered steel beams 11 evenly arranged in rows and several connecting rods 12;

[0051] Adjacent cantilever steel beams 11 are fixedly connected by at least two connecting rods 12;

[0052] Each of the cantilever steel beams 11 includes a main steel beam section 111, a ramp section 112, and a fixed section 113 that are integrally connected in sequence;

[0053] The main steel beam section 111 and the fixed section 113 are horizontal sections, and the inclined section 112 is inclined downward at a preset angle relative to the main steel beam section 111.

[0054] Each of the fixed segments 113 can be fixed to the building wall 4 at one end away from the ramp segment 112;

[0055] The lower ends of the plurality of tie rods 2 are hinged to the upper surface of the main steel beam section 111, and the upper ends can be fixed to the building wall 4;

[0056] The upper ends of the plurality of support rods 3 are hinged to the lower surface of the main steel beam section 111, and the lower ends can be fixed to the building wall 4.

[0057] In this embodiment, the steel platform body 1 is composed of several uniformly arranged cantilevered steel beams 11 and several connecting rods 12, with the connecting rods 12 connecting adjacent cantilevered steel beams 11. This makes the steel platform body 1 a horizontal truss structure, significantly reducing its self-weight compared to the traditional I-beam cantilevered platform 9. The number of connecting rods 12 between two adjacent cantilevered steel beams 11 can be set according to the size of the steel platform body 1. Specifically, when the distance between two adjacent cantilevered steel beams 11 is large and / or the length of the cantilevered steel beams 11 is long, more connecting rods 12 can be set, for example, five connecting rods 12, to avoid construction safety risks caused by excessive openwork; when the distance between two adjacent cantilevered steel beams 11 is small and / or the length of the cantilevered steel beams 11 is short, fewer connecting rods 12 can be set, for example, two connecting rods 12, to ensure that the steel platform body 1 is lightweight and has uniform stress.

[0058] Reference Figure 2As shown, the steel platform system suitable for formwork support of super high-rise, high-altitude, large-span cantilever structures can be set on the beams and slabs below the refuge floor, thereby solving the construction inconvenience caused by the outward protrusion of the cantilever platform 9 of the refuge floor. The steel platform body 1 is located below the cantilever platform 9 of the refuge floor, the upper end of the tie rod 2 is connected to the lower part of the refuge floor, and the lower end of the strut 3 is connected to the lower beams and slabs.

[0059] The steel platform system provided in this embodiment of the invention, applicable to formwork support for ultra-high-rise, high-span, large-span cantilever structures, utilizes cantilever steel beams 11 with sloping sections 112 to effectively resist downward deflection under cantilever stress, improving the reliability of the steel platform body 1 and reducing the risk of deformation. The steel platform body 1, formed by combining several cantilever steel beams 11 and several connecting rods 12, creates a hollow truss shape, ensuring structural reliability while effectively reducing its self-weight. This improves the reliability of the steel platform system and allows for convenient assembly and disassembly, increasing construction efficiency. The steel platform body 1, supported by tie rods 2 and struts 3, ensures sufficient strength and reliability for the steel platform system, effectively guaranteeing construction safety.

[0060] In an optional embodiment, the downward inclination angle of the ramp section 112 relative to the main steel beam section 111 is within the range of 45°. This avoids the cantilevered steel beam 11 bearing additional tensile stress, which could lead to a decrease in the stress performance of the steel platform body 1. This ensures that the steel platform body 1 can effectively resist downward deflection under cantilever stress, thereby improving the reliability of the steel platform body 1. Furthermore, the length of the ramp section 112 is 1 / 8 of the length of the main steel beam section 111, and the length of the fixed section 113 is 1 / 10 of the length of the main steel beam section 111. This avoids poor force transmission caused by the ramp section 112 and the fixed section 113 being too long, ensuring uniform stress on the steel platform body 1, reducing the risk of deformation and detachment of the cantilevered steel beam 11, and helping to ensure construction safety.

[0061] In an optional embodiment, refer to Figure 1 and Figure 2 As shown, the steel platform system suitable for formwork support of super high-rise, high-altitude, large-span cantilever structures also includes tie rod embedded parts 5. The tie rod embedded parts 5 can be embedded in the building wall 4. The upper end of the tie rod 2 is connected to the tie rod embedded parts 5 embedded in the beam slab of the refuge floor above the floor where the steel platform body 1 is located, so as to hinge the tie rod 2 to the building wall 4, thereby providing an upward tension for the steel platform body 1, increasing the load range that the steel platform can bear, avoiding deformation or detachment of the steel platform body 1 due to stress, and improving safety.

[0062] Optionally, the tie rod embedded part 5 can be a straight-through tie rod embedded part. The tie rod 2, the tie rod embedded part 5, and the cantilever steel beam 11 can all be hinged in the form of ear plates. The lower section of the tie rod 2 is hinged to the free end of the main body section 111 of the steel beam (the end away from the slope section 112), thereby avoiding downward bending deformation of the cantilever steel beam 11.

[0063] Optionally, the number of tie rods 2 can be reasonably set according to the size of the steel platform body 1. For example, a tie rod 2 can be connected to each cantilever steel beam 11 to ensure that the steel platform is subjected to uniform force.

[0064] In an optional embodiment, refer to Figure 1 and Figure 3 As shown, the tie rod 2 includes a telescopic rod 21 and an upper hinge 22 and a lower hinge 23 respectively fixed to both ends of the telescopic rod 21. The upper hinge 22 is hinged to the tie rod embedded part 5, and the lower hinge 23 is hinged to the upper surface of the main steel beam section 111, thereby realizing the hinge connection between the tie rod 2 and the building wall 4 and the cantilever steel beam 11.

[0065] In an optional embodiment, refer to Figure 3 As shown, the telescopic rod 21 includes a threaded sleeve 211, a positive threaded screw 212, and a negative threaded screw 213. The internal threads at both ends of the threaded sleeve 211 correspond to the external threads of the positive threaded screw 212 and the negative threaded screw 213, respectively. The two ends of the threaded sleeve 211 are respectively fitted onto and threadedly connected to the positive threaded screw 212 and the negative threaded screw 213. With the positive threaded screw 212 and the negative threaded screw 213 stationary, the length of the telescopic rod 21 can be adjusted by rotating the threaded sleeve 211, thereby adjusting the length of the pull rod 2 and enhancing its applicability to different steel platform sizes. The end of the positive threaded screw 212 furthest from the threaded sleeve 211 is fixedly connected to an upper hinge 22, and the end of the negative threaded screw 213 furthest from the threaded sleeve 211 is fixedly connected to a lower hinge 23. Optionally, both the upper hinge 22 and the lower hinge 23 can be lugs.

[0066] In an optional embodiment, refer to Figure 1 As shown, the steel platform system suitable for formwork support of super high-rise, high-span, large-span cantilever structures also includes steel beam embedded parts 7. The steel beam embedded parts 7 can be pre-embedded within the building wall 4, for example, using expansion bolts to fix them in the concrete through expansion, for connecting the cantilever steel beams 11. The end of the fixing section 113 away from the slope section 112 can be threaded to the steel beam embedded parts 7, thereby fixing the steel platform body 1 to the side of the building wall 4.

[0067] In an optional embodiment, refer to Figure 1As shown, the steel platform system suitable for formwork support of super high-rise, high-span, large-span cantilever structures also includes strut embedded parts 8. The strut embedded parts 8 can be pre-embedded within the building wall 4, for example, using expansion bolts to fix them in the concrete through expansion, and are used to connect ear plates, thereby achieving the hinged connection between the strut 3 and the cantilever steel beam 11. The lower end of the strut 3 is hinged to the strut embedded part 8, and the upper end is hinged to the cantilever steel beam 11.

[0068] In an optional embodiment, the steel beam embedded part 7, the tie rod embedded part 5, and the strut embedded part 8 can all adopt a structure combining fixed support and hinged support. The fixed support is partially embedded in the building wall, and the hinged support is used to hinge the cantilever steel beam 11, tie rod 2, and strut 3. The structural forms of the fixed support and the hinged support can be referred to in detail in the prior art, and will not be repeated here.

[0069] In an optional embodiment, refer to Figure 2 As shown, the steel platform system suitable for formwork support of ultra-high-rise, high-span, cantilever structures also includes a lower net 6 installed below the steel platform body 1. The lower net 6 can be fixed by welding hooks (not shown in the figure) to the bottom of the steel platform body, suspending and binding the lower net 6 to the hooks. Since the steel platform body 1 is a hollow truss structure, the lower net 6 effectively prevents construction tools, construction waste, etc., from falling below the building wall 4, ensuring the safety of construction personnel. The lower net 6 is a flexible net with high toughness and light weight, which will not increase the load on the steel platform system. For example, a net made of high-strength fiber material can be used to ensure sufficient strength and wear resistance. The mesh size of the net can be reasonably selected according to construction needs.

[0070] In an optional embodiment, the steel platform system suitable for formwork support of ultra-high-rise, high-span, cantilever structures further includes an upper protective plate (not shown in the figure) laid above the steel platform body 1. The protective plate forms a top protection, working in conjunction with the lower safety net 6 to further reduce the risk of objects falling and prevent construction workers from slipping, thus improving construction safety. After the protective plate is laid, scaffolding (not shown in the figure) can be erected on the upper part of the steel platform body 1 for construction operations. Furthermore, a dense safety net can be installed around the scaffolding to aid in safety protection. The protective plate can be made of a 15mm thick template.

[0071] The steel platform system provided in this embodiment is suitable for formwork support of super high-rise, high-altitude, large-span cantilever structures. It is applicable to projects where conventional cantilever I-beam type operating platforms cannot be used for super high-rise, high-altitude, large-span cantilever structures. After the steel platform system is installed on the building to be constructed, workers can carry out corresponding construction work on the exterior facade of the building on the platform.

[0072] In an optional embodiment, the steel platform system suitable for formwork support of ultra-high-rise, high-span, large-span cantilever structures further includes a monitoring system. The monitoring system includes a signal processing terminal (not shown in the figure), a first strain sensor 201, and a displacement sensor 205. The first stress sensor is disposed on the slope section 112 to monitor the stress in the slope section 112. The displacement sensor 205 is disposed at the end of the main steel beam section 111 away from the slope section 112 to monitor the vertical displacement of the end of the main steel beam section 111 away from the slope section 112. The signal processing terminal is wirelessly connected to the first strain sensor 201 and the displacement sensor 205. The signal processing terminal can issue a first-level warning when the monitoring result of the first strain sensor 201 exceeds a first preset strain threshold. After issuing a first-level warning, the signal processing terminal can also issue a second-level warning when the monitoring result of the displacement sensor 205 exceeds a preset displacement threshold.

[0073] In this embodiment, the first strain sensor 201 and the displacement sensor 205 can transmit the monitoring results to the signal processing terminal in the form of wireless signals; the signal processing terminal can receive and process the signals transmitted by the first strain sensor 201 and the displacement sensor 205, display the monitoring results of the first strain sensor 201 and the displacement sensor 205, and issue early warning information based on the monitoring results.

[0074] In this embodiment, the signal processing terminal can be a mobile phone, computer, or other device with wireless signal transmission and information display functions.

[0075] For example, after receiving the monitoring results from the first strain sensor 201 and the displacement sensor 205, the signal processing terminal determines whether the monitoring result of the first strain sensor 201 exceeds a first preset strain threshold, and simultaneously determines whether the monitoring result of the displacement sensor 205 exceeds a preset displacement threshold. If the monitoring result of the first strain sensor 201 exceeds the first preset strain threshold, a level one warning is issued; if the monitoring result of the first strain sensor 201 exceeds the first preset strain threshold and the monitoring result of the displacement sensor 205 exceeds the preset displacement threshold, a level two warning is issued. The warning information alerts workers to potential safety risks, and the tiered warning system visually demonstrates the degree of danger, which is beneficial for ensuring construction safety. The specific implementation methods of monitoring and warning can be found in the detailed descriptions in existing technologies, and will not be elaborated here.

[0076] Obviously, a corresponding early warning can be set only when the monitoring result of displacement sensor 205 exceeds the preset displacement threshold. The specific settings can be reasonably configured according to the actual working conditions.

[0077] In this embodiment, the sloping section 112 of the cantilever steel beam 11 can effectively resist downward deflection under cantilever stress. The strain of the sloping section 112 under stress on the steel platform body 1 is more significant than that of other sections. Therefore, setting a first strain sensor 201 on the sloping section 112 can more efficiently monitor the stress on the steel platform body 1, thereby providing timely warnings when there is a risk of excessive stress on the steel platform body 1, improving construction safety. The deformation of the steel platform body 1 under stress is mainly manifested in the downward tilting of the steel platform body 1. If downward tilting occurs, the downward displacement is most significant at the end of the cantilever steel beam 11 away from the building. Therefore, setting a displacement sensor 205 at the end of the main section 111 of the steel beam away from the sloping section 112 can effectively monitor the deformation of the steel platform body 1, thereby providing timely warnings when the steel platform body 1 deforms under excessive stress, improving construction safety. By distinguishing between first-level and second-level warnings, the degree of danger can be more intuitively indicated, facilitating timely risk management by operators according to different situations, ensuring construction safety, and avoiding major risks.

[0078] In this embodiment, refer to Figure 1 and Figure 2 As shown, the monitoring system also includes a second strain sensor 202, a third strain sensor 203, and a fourth strain sensor 204. The second strain sensor 202 is disposed on the lower surface of the main steel beam section 111; the third strain sensor 203 is disposed on the tie rod 2; and the fourth strain sensor 204 is disposed on the strut 3. A signal processing terminal wirelessly connects to the second strain sensor 202, the third strain sensor 203, and the fourth strain sensor 204. The signal processing terminal can issue a first-level warning when the monitoring result of the second strain sensor 202 exceeds a second preset strain threshold, and / or when the monitoring result of the third strain sensor 203 exceeds a third preset strain threshold, and / or when the monitoring result of the fourth strain sensor 204 exceeds a fourth preset strain threshold. After issuing a first-level warning, the signal processing terminal can issue a second-level warning when the monitoring result of the displacement sensor 205 exceeds a preset displacement threshold.

[0079] In this embodiment, the second strain sensor 202, the third strain sensor 203, and the fourth strain sensor 204 can transmit the monitoring results to the signal processing terminal wirelessly. The signal processing terminal can receive and process the signals transmitted by the second strain sensor 202, the third strain sensor 203, and the fourth strain sensor 204, display the monitoring results of the second strain sensor 202, the third strain sensor 203, and the fourth strain sensor 204, and issue corresponding warning information based on the monitoring results. The process by which the signal processing terminal makes judgments and issues warnings based on the received monitoring results can refer to the process by which it processes the monitoring results of the first strain sensor 201 and the displacement sensor 205. Where the process is repeated, it will not be described again.

[0080] In this embodiment, refer to Figure 1 and Figure 2 As shown, tie rod 2 and strut 3 are connected to the steel platform body 1 to form a stable system. Tie rod 2 provides an upward tensile force to the steel platform body 1, and strut 3 provides an upward supporting force, ensuring the reliability of the steel platform body 1 and effectively reducing the risk of deformation and detachment. When the steel platform body 1 is subjected to excessive force, the cantilever steel beam 11, tie rod 2, and strut 3 will all experience corresponding strain. The strain of the cantilever steel beam 11 and tie rod 2 is monitored in real time by the second strain sensor 202, and the strain of the tie rod 3 is monitored in real time by the third strain sensor 203. This allows for comprehensive monitoring of the stress on the entire steel platform system, timely identification of the system's stress safety status, and thus prevention of risks and improvement of construction safety.

[0081] In this embodiment, when the signal processing terminal issues a Level 1 warning, the location of the unreliable risk can be identified by checking the sensors that triggered the warning. For example, if a third strain sensor 203 detects that the strain of the corresponding tie rod 2 exceeds a third preset strain threshold, it can be determined that the tie rod 2 is under excessive force, and corresponding safety measures can be taken, such as reducing the number of objects on the steel platform body 1. When the signal processing terminal issues a Level 2 warning, it indicates that the steel platform body 1 has begun to tilt downwards, which more effectively alerts workers to the potential safety risks.

[0082] In this embodiment, it is not necessary to install the first strain sensor 201 and the second strain sensor 202 on every cantilever steel beam 11. They can be installed on important cantilever steel beams 11 (such as those at the edges) and then spaced out in the other cantilever steel beams 11 to save costs. Similarly, it is not necessary to install the third strain sensor 203 and the fourth strain sensor 204 on every tie rod 2 and strut 3; only important tie rods 2 and struts 3 need to be selected for installation.

[0083] The steel platform system provided in this embodiment, applicable to formwork support of super high-rise, high-altitude, large-span cantilever structures, enables real-time monitoring of the strain and deformation of the steel platform body 1 by setting a first strain sensor 201 on the slope section 112 and a displacement sensor 205 at the end of the main steel beam section 111. This allows for timely knowledge of the stress and safety status of the steel platform body 1, preventing risks and providing strong protection for construction safety.

[0084] The installation process of the steel platform system for formwork support of super high-rise, high-altitude, large-span cantilever structures provided in this embodiment of the utility model may specifically include:
