Description

Technical Field

[0001] This utility model relates to the field of attached lifting scaffolding support technology, and in particular to an attached lifting scaffolding support system. Background Technology

[0002] When the roof layer (RF) has lines that extend beyond the outer edge of the standard floor structure plane, and the project's roof frame is an arc-shaped frame layer 3.3 meters to 5.5 meters above the structural surface, and the existing attached lifting scaffold has a single climbing height of 2.9 meters, it is impossible to install conventional climbing scaffold attachment supports on the arc-shaped frame layer in this situation, and it exceeds the vertical protection coverage of the standard climbing scaffold. As a result, the existing attached lifting scaffold support system cannot meet the support requirements.

[0003] For example, Chinese patent application CN117027347A discloses a protective system for building construction using attached lifting scaffolding, including a building under construction, attached lifting scaffolding, and a tying mechanism. The building under construction comprises several floors. The uppermost floor without concrete pouring is designated as the structural floor, and the floors below and adjacent to the structural floor with concrete pouring are designated as the roof floor. The top of the attached lifting scaffolding is vertically positioned above the top surface of the structural floor, and the vertical distance between the top of the attached lifting scaffolding and the top surface of the structural floor is greater than or equal to the safety protection height. The attached lifting scaffolding is rigidly tied to the roof floor via the tying mechanism. This invention eliminates the need to dismantle the attached lifting scaffolding around the uppermost, unfinished floor and install guardrails when constructing a new floor, saving significant manpower, resources, and time. The tie structure includes several steel pipes and several steel pipe fasteners. The steel pipes include pre-embedded piles vertically fixed to the roof layer, a first connecting rod fixedly connected to the pre-embedded piles and equipped with the connecting groove, and a second connecting rod connecting two adjacent steel pipes. The joints of any two steel pipes are fixedly connected together by steel pipe fasteners. Although the tie structure rigidly connects the attached lifting scaffold to the roof layer, the tie structure is a purely rigid structure. It is mainly used to support the attached lifting scaffold and to prevent the attached lifting scaffold from overturning. However, it is difficult to provide upward support force, which results in low protective stability of the attached lifting scaffold. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing attached lifting scaffolding support systems in the prior art, which cannot meet the support height requirements, and to provide an attached lifting scaffolding support system.

[0005] This utility model provides an attached lifting scaffold support system, including an attached lifting scaffold and a reinforcement system. The attached lifting scaffold includes an outer protective layer, a plurality of vertical guide rails connected to the inner side of the outer protective layer and arranged at horizontal intervals, and a plurality of attached supports that cooperate with each of the vertical guide rails and are arranged at vertical intervals. The height difference between the top of the outer protective layer and the uppermost attached support is greater than the height difference between the highest point of the frame and the current roof structural beam. The height difference between the highest point of the frame and the current roof structural beam is greater than the distance between two adjacent attached supports in the vertical direction. The reinforcement system includes a diagonal bracing steel pipe device and a double steel wire rope tying device. The diagonal bracing steel pipe device includes several diagonal bracing steel pipes, and the top of each vertical guide rail is supported by the diagonal bracing steel pipes to the current roof structural beam. The double steel wire rope tying device includes several first steel wire ropes corresponding to the diagonal bracing steel pipes and second steel wire ropes corresponding to the vertical guide rails. The top of each vertical guide rail is tied to the current roof structural beam by the first steel wire ropes, and the part of each vertical guide rail located below the uppermost attachment support is tied to the current roof structural beam by the second steel wire ropes.

[0006] Preferably, the portion of the outer protective layer that is higher than the uppermost attachment support and misaligned with the vertical guide rail is supported by the diagonal bracing steel pipe and tied by the first steel wire rope.

[0007] Preferably, the horizontal spacing of the diagonal bracing steel pipes is less than or equal to 2m, the angle between the diagonal bracing steel pipe and the horizontal plane is less than or equal to 45°, and the vertical height of the diagonal bracing steel pipe is less than or equal to 3800mm.

[0008] Preferably, an embedded part is pre-embedded in the top of the current roof structural beam. The embedded part is embedded to a depth of 200mm or more in the top surface of the current roof structural beam. The embedded part extends out of the top surface of the current roof structural beam. The lower end of the diagonal bracing steel pipe is connected to the part of the embedded part that extends out of the top surface of the current roof structural beam. The upper end of the diagonal bracing steel pipe is connected to the vertical guide rail by a fastener.

[0009] Preferably, the embedded part is a steel structure, and the portion of the embedded part extending out of the top surface of the current roof layer structural beam is welded to the lower end of the diagonal bracing steel pipe.

[0010] Preferably, the portion of the embedded part extending beyond the top surface of the current roof structural beam is inclined in the same direction as the lower end of the diagonal bracing steel pipe, and the portion of the embedded part extending beyond the top surface of the current roof structural beam is welded to the lower end of the diagonal bracing steel pipe.

[0011] Preferably, the embedded part is a pair of parallel double steel bars, the part of the double steel bars extending out of the top surface of the current roof layer structural beam is inclined in the same direction as the lower end of the diagonal bracing steel pipe, and there is a gap between the double steel bars.

[0012] Preferably, a pull ring is pre-embedded at the top of the current roof layer structural beam, and the lower end of the first wire rope and the upper end of the second wire rope are both connected to the pull ring. The other ends of the first wire rope and the second wire rope are both sleeved on the horizontal bar of the vertical guide rail.

[0013] Preferably, the pull ring is a double-reinforced pull ring, and the double-reinforced pull rings are arranged side by side.

[0014] Preferably, each end of the first wire rope and the second wire rope has no fewer than four clips; And / or, the diameter of the second wire rope is greater than the diameter of the first wire rope.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an attached lifting scaffolding support system. Each vertical guide rail is supported by diagonal steel pipes between its top and the current roof structural beam. Simultaneously, a first steel wire rope, utilizing the current roof structural beam, pulls the vertical guide rails downwards at an angle. The tension of the first steel wire rope and the thrust of the diagonal steel pipes create a force couple, balancing the overturning moment and preventing the attached lifting scaffolding from tipping over. A second steel wire rope, also utilizing the current roof structural beam, pulls the vertical guide rails upwards at an angle, providing additional safety reserves at critical points. This further limits the deformation of the attached lifting scaffolding under extreme conditions, allowing for higher support heights without connecting the highest point of the structure via attachment supports, thus meeting support height requirements.

[0018] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0019] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0020] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are set as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," "parallel," or "coaxial" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0021] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0022] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0023] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0024] Example 1 like Figure 7 As shown, from left to right, these are the results of the attached lifting scaffold 1 climbing to different construction levels. From left to center and center to right, the attached lifting scaffold 1 rises one level at a time during construction, and is then fixed to the uppermost structure via the attachment supports 13. From center to right, it can be seen that because the height difference between the highest point 4 of the frame and the current roof beam 3 is greater than the distance between two adjacent vertical attachment supports 13 (the distance between two adjacent vertical attachment supports 13 is the standard lifting height of the attached lifting scaffold, such as 2.9m), even after rising one level, the uppermost attachment support 13 cannot be fixed to the highest point 4 of the frame. This results in a large unsupported height of the uppermost outer protective layer 11 of the attached lifting scaffold 1, which does not meet the protection force requirements. Consequently, the uppermost outer protective layer 11 cannot be set to the required height, and the height difference between the top of the outer protective layer 11 and the uppermost attachment support 13 cannot be greater than the height difference between the highest point 4 of the frame and the current roof beam 3.

[0025] This embodiment provides an attached lifting scaffolding support system, including an attached lifting scaffolding 1 and a reinforcement system. The reinforcement system uses the roof structural beam 3 of the roof layer below the highest point 4 of the frame as the stress point. The attached lifting scaffolding 1 and the roof structural beam 3 are reinforced together by the reinforcement system, so that the height difference between the top of the outer protection 11 and the uppermost attached support 13 is greater than the height difference between the highest point 4 of the frame and the current roof structural beam 3, thus meeting the protection height requirements.

[0026] In this embodiment, the attached lifting scaffold 1 includes an outer protective layer 11, a plurality of horizontally spaced vertical guide rails 12 connected to the inner side of the outer protective layer 11, and a plurality of vertically spaced attachment supports 13 that cooperate with each of the vertical guide rails 12. The difference between this attached lifting scaffold 1 and existing attached lifting scaffold 1 is that the height of the outer protective layer 11 above the uppermost attachment support 13 is greater, needing to be greater than the height difference between the highest point 4 of the frame and the current roof structural beam 3. This increased height of the outer protective layer 11 above the uppermost attachment support 13 can be achieved by removing the uppermost attachment support 13, for example... Figure 7 As shown, the attached lifting scaffold 1 on the left and in the middle is equipped with three attachment supports 13, while the attached lifting scaffold 1 on the right is equipped with only two attachment supports 13. By removing the top attachment support 13, the topmost attachment support 13 becomes the second attachment support 13, thus increasing the height of the outer protective layer 11 above the topmost attachment support 13. At the same time, removing the top attachment support 13 provides a stress point for the reinforcement system at the top of the vertical guide rail 12. In addition to the above differences, like conventional attached lifting scaffold 1, the attached lifting scaffold 1 is also equipped with a fall arrest device, a power device, and a control device, which enables the attached lifting scaffold 1 to rise and prevent it from falling.

[0027] The reinforcement system includes a diagonal bracing steel pipe device and a double steel wire rope tying device. The diagonal bracing steel pipe device includes several diagonal bracing steel pipes 21, and each of the vertical guide rails 12 is supported by the diagonal bracing steel pipes 21 at its top. The double steel wire rope tying device includes several first steel wire ropes 22 corresponding to the diagonal bracing steel pipes 21 and second steel wire ropes 23 corresponding to the vertical guide rails 12. That is, each diagonal bracing steel pipe 21 is equipped with a corresponding first steel wire rope 22. Figure 1 and Figure 2 As shown, a first steel wire rope 22 and a diagonal bracing steel pipe 21 are provided between the top of the vertical guide rail 12 and the current roof structural beam 3. The top of each vertical guide rail 12 is connected to the current roof structural beam 3 via the first steel wire rope 22. Simultaneously, the first steel wire rope 22, using the current roof structural beam 3, pulls the vertical guide rail 12 downwards at an angle. The tension of the first steel wire rope 22 and the thrust of the diagonal bracing steel pipe 21 form a couple, balancing the overturning moment and preventing the attached lifting scaffold 1 from overturning. Optional implementation methods include... Figure 6As shown, outside the vertical guide rail 12, between the top of the outer protective layer 11 and the current roof structural beam 3, a first steel wire rope 22 and a diagonal bracing steel pipe 21 are also provided. That is, the part of the inner side of the outer protective layer 11 that is higher than the uppermost attachment support 13 and misaligned with the vertical guide rail 12 is supported by the diagonal bracing steel pipe 21 and connected by the first steel wire rope 22. The tension of the first steel wire rope 22 and the thrust of the diagonal bracing steel pipe 21 can form a couple to balance the overturning moment and prevent the attached lifting scaffold 1 from overturning. This arrangement makes the reinforcement of the top of the attached lifting scaffold 1 and the current roof structural beam 3 more stable; and as Figure 1 and Figure 2 As shown, each of the vertical guide rails 12 located below the uppermost attachment support 13 is connected to the current roof structural beam 3 by the second steel wire rope 23. The second steel wire rope 23 utilizes the current roof structural beam 3 to tilt and pull the vertical guide rail 12 upward, providing additional safety reserves at critical locations and further limiting the deformation that the attached lifting scaffold 1 may undergo under extreme working conditions. This allows for setting a higher support height without connecting the highest point 4 of the frame through the attachment support 13, thus meeting the support height requirements.

[0028] In an optional embodiment, the horizontal spacing of the diagonal bracing steel pipes 21 is less than or equal to 2m, such as... Figure 5 As shown, the horizontal spacing of the diagonal bracing steel pipes 21 is set at 1500mm; the angle between the diagonal bracing steel pipe 21 and the horizontal plane is less than or equal to 45°, and the vertical height of the diagonal bracing steel pipe 21 is less than or equal to 3800mm. Using Φ48×3 diagonal bracing steel pipes 21 with a horizontal spacing of no more than 2.0 meters ensures the uniformity of the support. Strictly controlling the angle between the steel pipe and the horizontal plane to no more than 45 degrees, and ensuring the length between the upper and lower tie points does not exceed 3800mm, guarantees that the diagonal bracing has optimal stress state and stiffness, effectively resisting overturning moments.

[0029] Both ends of the aforementioned diagonal bracing steel pipe 21, first wire rope 22, and second wire rope 23 need to be connected to ensure the stability of the load. This embodiment provides some preferred connection methods. An embedded part 211 is pre-embedded in the top of the current roof structural beam 3. The depth of the embedded part 211 in the top surface of the current roof structural beam 3 is greater than or equal to 200mm to ensure the pre-embedding strength. The embedded part 211 extends out of the top surface of the current roof structural beam 3, which facilitates the connection between the lower end of the diagonal bracing steel pipe 21 and the part of the embedded part 211 that extends out of the top surface of the current roof structural beam 3. The upper end of the diagonal bracing steel pipe 21 is connected to the vertical guide rail 12 through a fastener 212, which facilitates disassembly from the vertical guide rail 12 later and avoids later cutting, so that the attached lifting scaffold 1 can be reused. Of course, the connection between the diagonal bracing steel pipe 21 and the outer protection 11 is also achieved through a fastener 212.

[0030] Furthermore, the embedded part 211 is a steel structure. The portion of the embedded part 211 extending beyond the top surface of the current roof structural beam 3 is welded to the lower end of the diagonal bracing steel pipe 21. This operation is relatively convenient, and the connection strength formed after welding is higher, which is beneficial to improving the stability of the reinforcement. Furthermore, the portion of the embedded part 211 extending beyond the top surface of the current roof structural beam 3 is inclined in the same direction as the lower end of the diagonal bracing steel pipe 21. The portion of the embedded part 211 extending beyond the top surface of the current roof structural beam 3 is welded to the lower end of the diagonal bracing steel pipe 21. Figure 4 As shown, this allows for longer weld lengths, with weld lengths between reinforcing bars and steel pipes ≥100mm and weld heights ≥5mm, improving weld quality and thus enhancing reinforcement stability. Figure 4 As shown, the angle between the portion of the embedded part 211 extending from the top surface of the current roof structural beam 3 and the bottom embedded part is 120°-135°, that is, the angle between the portion of the embedded part 211 extending from the top surface of the current roof structural beam 3 and the horizontal plane is 30°-45°, and the angle between the diagonal bracing steel pipe 21 and the horizontal plane is 30°-45°. This ensures that the diagonal bracing has the best stress state and stiffness, effectively resisting the overturning moment. The embedded part 211 consists of parallel double reinforcing bars. The portion of the double reinforcing bars extending from the top surface of the current roof structural beam 3 is inclined in the same direction as the lower end of the diagonal bracing steel pipe 21. There is a gap between the double reinforcing bars, which allows for a smaller embedded reinforcing bar size, while providing a larger welding area for the diagonal bracing steel pipe 21. This avoids difficulties in the later processing of the embedded parts, improves welding quality, and enhances the stability of the reinforcement.

[0031] For the connection between the first wire rope 22 and the second wire rope 23 and the current roof structural beam 3, a pull ring 223 is pre-embedded in the top of the current roof structural beam 3, such as... Figure 2 As shown, the lower end of the first wire rope 22 and the upper end of the second wire rope 23 are both connected to the pull ring 223, and the other ends of the first wire rope 22 and the second wire rope 23 are both sleeved on the horizontal rod 121 of the vertical guide rail 12. Figure 2As shown, the pull ring 223 is a double-reinforced pull ring 223, arranged side by side. This arrangement allows the other pull ring to remain usable even if one is damaged, thus improving safety. Each end of the first wire rope 22 and the second wire rope 23 has at least four clips, ensuring absolute reliability and enhancing overall stability. The diameter of the second wire rope 23 is larger than that of the first wire rope 22, providing better protection. For example, if the first wire rope 22 uses a Φ10 wire rope, its upper end connects to a key node on the vertical guide rail of the attached lifting scaffold, and its lower end is anchored to a pull ring pre-embedded in the roof layer, forming the main tie. The second wire rope 23 uses a thicker Φ12 wire rope, specifically located at the critical stress point of the machine position guide rail, further strengthening the tie.

[0032] Using the attached lifting scaffolding support system described in this embodiment, after the attached lifting scaffolding is raised to the roof level, the uppermost third attached support is installed on the floor in front of the roof level, i.e. Figure 7 The diagram shows that the height of the outer protective netting 11 exceeds the roof structure surface. During the construction of the roof structure beam 3, Φ22 parallel double steel bars with a pre-embedded depth ≥200mm and Φ20 double steel bar tie rings extending 100mm out of the structure surface are used as the foundation for subsequent diagonal bracing steel pipes and tie wire ropes, ensuring the stable attachment and continuous protection of the attached lifting scaffold on the roof. After the roof beams and slabs are poured and reach their strength, the attached lifting scaffold is lifted for the last time. The bottom walkway of the attached lifting scaffold is 1100mm from the standard floor structure surface. The third attachment support at the top is removed, and the two attachment supports at the bottom are retained. The second attachment support is fixed to the roof layer and serves as the uppermost attachment support of the attached lifting scaffold support system of this application. The original third attachment support is reinforced to the roof structural beam with wire ropes and diagonal bracing steel pipes. Specifically, a diagonal bracing steel pipe device is set to prevent overturning: Φ48×3 diagonal bracing steel pipes are used, with a horizontal spacing of ≤2.0 meters, an angle of ≤45° with the horizontal plane, and a length between upper and lower nodes of ≤3800mm. A double wire rope tie device is set: the first Φ10 wire rope connects the vertical guide rail of the attached lifting scaffold to the pre-embedded tie ring, and the second Φ12 wire rope is set at the machine position guide rail, with no less than 4 buckles at each end to enhance overall stability.

[0033] Flexible subsystem – double wire rope tie device: ① Tiered Setup: Two safety barriers are in place. The first barrier is a Φ10 steel wire rope, with its upper connection point near the connection point between the diagonal bracing steel pipe and the guide rail, and its lower end anchored to a pre-embedded Φ20 double-reinforcing bar ring. The second barrier is a Φ12 steel wire rope, specifically installed at the most critical location on the machine position guide rail. Its upper tie point is also located at the pre-embedded tie ring, and its lower tie point is connected to the structure between the roof layer and the next floor.

[0034] ② Force Coordination: As a flexible component, the wire rope can only withstand tensile force. The first Φ10 wire rope works in conjunction with the diagonal bracing pipe. When the attached lifting scaffold tends to tilt outward, the wire rope is immediately under tension, forming a force couple with the pressure or tension of the diagonal bracing to balance the overturning moment. The second Φ12 wire rope serves as a "safety redundancy," providing additional safety reserves in critical areas, further limiting the deformation of the attached lifting scaffold under extreme conditions.

[0035] ③ Node reliability: Extremely high requirements are placed on the fixing of the wire rope ends. It is stipulated that no less than 4 wire rope clips should be used at each end and tightened in the specified direction to ensure the reliability of the flexible knot end.

[0036] ④ Functional Positioning: The wire rope tie acts as the "tendon" of the support system, providing flexible tension and safety redundancy. It complements the rigid diagonal brace, forming a statically indeterminate structural system that constrains the attached lifting scaffold in three-dimensional space, greatly improving the overall reliability and risk resistance of the support system.

[0037] The attached lifting scaffolding support system described in this embodiment innovatively adopts an unconventional support system of "two attached supports + two top steel wire rope ties + diagonal bracing steel pipe supports". Traditional attached lifting scaffolding relies on three attached supports to ensure stability. In this project, after the completion of the roof structure construction, through precise calculation and verification, when the attached lifting scaffolding was raised to the target height for the last time, the conventional attached support at the third level was actively removed, and the top support was also removed, which essentially increased the height of the cantilever section of the attached lifting scaffolding. This would inevitably lead to a significant increase in the deflection deformation at the top free end of the attached lifting scaffolding and the overturning moment at the root. Instead, an innovative ties and reinforcement system combining "diagonal bracing steel pipes" and "double steel wire ropes" was used at the original attached support location, reliably connecting it to the roof structural beams. Through this reinforcement system, the horizontal and vertical loads originally borne by the third attached support were transferred to the roof structural beams with sufficient load-bearing capacity. This transformation allows the attached lifting scaffold to retain only two attachment supports in its final working state, successfully achieving "overtravel" lifting within a limited height, extending its protection range to cover tall roof structures. A double wire rope tying device is used: two safety lines are established. The first uses a Φ10 wire rope, with its upper end connected to a key node on the vertical guide rail of the attached lifting scaffold, and its lower end anchored to a pre-embedded pull ring in the roof layer, forming the main tying. The second uses a thicker Φ12 wire rope, specifically located at the critical stress point on the guide rail, further strengthening the tying. All wire rope joints are strictly installed according to specifications, with no fewer than four clips at each end, ensuring absolute reliability of the connection. A "spatial composite anti-overturning system" is constructed to ensure safety at extreme heights. After eliminating one attachment support, a spatial composite anti-overturning system composed of diagonal bracing steel pipes and wire rope tying is specially designed to compensate for and enhance the overall stability of the attached lifting scaffold. This solution has been successfully applied in the project, which not only safely and efficiently solved the construction protection problem of irregular roof structures and ensured the safety of the entire subsequent decoration and finishing work surface, but also provided a valuable engineering example that can be replicated and promoted for handling similar ultra-high and over-limit structures with its innovation and reliability.

[0038] Economic benefits: This utility model achieves significant economic value through technological innovation. Its economic benefits can be divided into three main categories: direct economic benefits, indirect economic benefits, and risk cost avoidance.

[0039] I. Direct economic benefits: The cost of the measures is significantly reduced. The direct economic benefits come from the cost savings brought about by the utility model itself compared to the traditional solution.

[0040] 1. Savings in material rental and turnover costs: Comparative solution: If a ground-supported steel pipe scaffolding is erected to the top of the roof structure (approximately 5.5 meters high), a large number of steel pipes, fasteners, scaffold boards, and safety nets will need to be rented.

[0041] Cost-saving calculation: Based on the project's perimeter of approximately 150 meters and a construction height exceeding 50 meters, the estimated investment in material rental alone would be approximately 300,000 to 500,000 RMB (depending on the rental period). This innovative solution, however, utilizes only a small amount of existing steel pipes, fasteners, and wire ropes, resulting in incremental material costs of less than 50,000 RMB.

[0042] Savings: This item directly saves 250,000 to 450,000 yuan.

[0043] 2. Labor cost savings: Comparative approach: The erection and dismantling of ground-based scaffolding is a labor-intensive operation that requires a large number of scaffolders and takes several weeks to complete.

[0044] Cost-saving calculation: The labor cost for erecting and dismantling traditional scaffolding is estimated at approximately 150,000 to 200,000 yuan. The lifting and reinforcement work of the attached lifting scaffolding in this solution can be completed by a small number of workers within a few days, with a labor cost of approximately 20,000 to 30,000 yuan.

[0045] Savings: This item directly saves 120,000 to 170,000 yuan.

[0046] 3. Savings in machinery and transportation costs: Comparative approach: The entry, exit, and on-site turnover of large quantities of scaffolding materials require frequent use of tower cranes, construction elevators, and freight vehicles, resulting in high machinery operating costs and transportation costs.

[0047] Cost savings estimate: This expense is approximately 50,000 to 80,000 yuan. This plan incurs almost no additional machinery transportation costs.

[0048] Savings: This item saves 50,000 to 80,000 yuan.

[0049] Total direct economic benefits: Considering the above three factors, this innovative solution saves approximately RMB 420,000 to 700,000 in direct costs compared to the traditional ground-mounted scaffolding solution.

[0050] II. Indirect Economic Benefits: The Value of Construction Period and Efficiency Becomes Prominent The indirect economic benefits stem from the combined gains resulting from shorter construction periods and improved management efficiency.

[0051] 1. Benefits of shortened construction period: Time value: This is a real estate project, and early delivery means faster capital recovery. The solution saves at least 2-3 weeks of critical construction time.

[0052] Benefit Calculation: Based on the overall project investment and industry practice, each day the construction period is shortened can save several thousand to tens of thousands of yuan in project management fees and financial costs. This alone can result in savings of hundreds of thousands of yuan.

[0053] Market value: Early completion and delivery help developers sell and deliver properties ahead of time, seizing market opportunities and generating significant potential sales revenue and cash flow benefits.

[0054] 2. Improved management efficiency: Simplified management: As an integrated platform, the daily maintenance and safety inspection of attached lifting scaffolding are far less complex than those of large, scattered ground scaffolding, saving safety officers and construction workers a great deal of management effort.

[0055] Smooth workflow transitions: This avoids work interruptions and downtime caused by scaffolding erection and dismantling, improves overall construction efficiency, and reduces coordination costs.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
