Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a double climbing scaffold for the construction of fourth-generation residential terraces and its construction method. Background Technology

[0002] With the development of fourth-generation housing, facades now feature numerous open terraces and balconies. Traditional climbing scaffolding systems typically employ single-layer integral climbing scaffolding or integrated exterior wall protection systems. However, when there are significant open areas in the terraces and balconies, traditional climbing scaffolding systems struggle to provide continuous and complete three-dimensional protection. 1. There is a "gap" on the outside of the terrace area: Traditional climbing scaffolds cannot form effective support and enclosure in the terrace area, resulting in a blind spot in protection; 2. Safety hazards exist during construction: There is a risk of workers falling from heights during construction and material stacking in the terrace area; 3. Limited climbing method: When the entire climbing frame is being raised, the terrace area cannot be protected simultaneously, requiring temporary scaffolding or safety nets to be erected, which increases the construction period and cost; 4. Inconvenient reuse of attachment devices: Attachment devices, anchors, etc., require a large amount of consumption or frequent turnover, affecting construction efficiency; 5. The dismantling of the structural supports for the cantilevered section occurred later than the climbing scaffolding's ascent, resulting in unprotected work and extremely high construction risks; 6. The traditional approach is to dismantle the climbing scaffold and then use a suspended platform for secondary construction of the remaining exterior walls, which is costly and poses significant safety hazards.

[0003] Therefore, a new climbing formwork system is needed that can provide supplementary protection for the open terrace area while ensuring the overall protection of the building facade, and can coordinate the construction of synchronous and independent lifting of the climbing formwork. Summary of the Invention

[0004] To address the aforementioned problems and technical issues, this invention provides a double-climbing scaffold for the construction of fourth-generation residential terraces and its construction method.

[0005] A double-climbing scaffold for the construction of terraces in fourth-generation residential buildings includes: a vertical main frame, installed along the outer side of the building structure; wall-mounted supports, installed on the vertical main frame, for attaching the vertical main frame to the building structure; and a lifting system connected to the vertical main frame, for driving the entire scaffold to rise and fall synchronously along the building structure; characterized in that: The vertical main frame is provided with an upper climbing frame assembly and a lower climbing frame assembly along the height direction. The upper climbing frame assembly includes an upper platform load-bearing beam assembly and an upper operating platform mounted thereon; The lower climbing frame assembly is a frame structure with independent protection function, which includes a lower platform load-bearing beam assembly, a lower operating platform, and protective components set around the lower operating platform. The lower climbing frame assembly and the upper climbing frame assembly are set independently of each other, and they do not enclose each other to form a closed structure. A fall protection structure is provided between the upper climbing scaffold assembly and the lower climbing scaffold assembly. The fall arrestor works synchronously with the vertical main frame during the scaffolding lifting process to limit abnormal downward displacement of the upper climbing scaffold assembly relative to the lower climbing scaffold assembly.

[0006] Preferably, the fall protection structure includes a fall protection connector and a guide limiting component, wherein the fall protection connector is connected to the upper climbing frame assembly and the vertical main frame, respectively.

[0007] Preferably, the guide limiting member is arranged along the vertical main frame to guide the fall arrestor structure to move synchronously with the vertical main frame during the scaffolding lifting and lowering process. Preferably, the protective component includes at least one of a protective pole, a protective railing, and a protective net.

[0008] Preferably, the upper climbing frame assembly and the lower climbing frame assembly are arranged in a staggered manner along the vertical direction.

[0009] Preferably, the vertical main frame is composed of uprights, horizontal bars and diagonal support components, forming a multi-layer spatial truss structure at the positions corresponding to the upper and lower climbing frame components.

[0010] A construction method for a double-climbing scaffold for fourth-generation residential terrace construction, the method comprising the following steps: S1. Before the main structure is constructed, an upper climbing scaffold is erected on the outside of the main building to allow it to form an initial attachment with the building structure through attachment devices and anti-fall components; S2. After the main structure has completed the pouring of one layer of concrete and reached the predetermined strength, drive the upper climbing frame to lift one layer as a whole and re-establish attachment connection with the main structure; S3. After the upper climbing scaffold is lifted, it forms a gap of at least two floors with the main structure. On the ground, a lower climbing scaffold with independent protection functions is assembled for each balcony or terrace area. S4. Under the premise that the upper climbing frame is stably attached, the lower climbing frames are lifted in sections and in stages according to the arrangement sequence of the balconies or terraces. After the lower climbing frame of one balcony is lifted and fixed, the lower climbing frame of the next balcony is lifted. The lower climbing frames do not interfere with each other during the lifting process. S5. During the construction of the main structure and balconies and terraces, the upper climbing scaffold provides overall protection for the building facade, while the lower climbing scaffold provides supplementary protection for the open balcony area, thus achieving continuous three-dimensional protection for the facade. S6. After the completion of all structural construction, dismantle the upper and lower climbing scaffolds according to the principle of "first erect, then dismantle" and "last erected, first dismantle", and seal the attachment holes.

[0011] Preferably, during the lifting process of the upper and lower climbing frames, only the attachment device and fall arrestor components are reused, and the reuse includes: Materials for attachment devices and fall protection components are hoisted through the pre-reserved openings in the flaps at the climbing frame location. When the concrete pouring is completed and the climbing is in preparation, the bottom wall supports and fall protection components are removed and concentrated. Using manual hoisting inside the frame, the dismantled attachment devices and fall protection components are hoisted from the lower level to the current working level; The attachment device and fall arrestor components were reinstalled in the upper structure for continued use.

[0012] Preferably, in step S4, the lower climbing frame is lifted one by one according to the individual balcony, and the upper climbing frame is always lifted synchronously as a whole, while the lower climbing frame is lifted independently, thereby avoiding the construction state without protection in the open area.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Achieve overall protection of the building facade and supplementary protection for open areas: The upper climbing scaffold is responsible for the overall protection of the building facade, while the lower climbing scaffold provides independent protection for the open areas of terraces and balconies, ensuring continuous protection of the facade during construction; 2. The structures are not closed to each other, reducing construction difficulty: The upper and lower climbing frames are set up independently and do not enclose each other to form a closed structure, which facilitates erection, lifting and dismantling; 3. Fall arrestor structure enhances safety: The fall arrestor structure limits the abnormal descent of the upper climbing frame relative to the lower climbing frame during the lifting process, ensuring the safety of the overall structure; 4. Material reuse reduces costs: The attachment device and fall arrestor can be removed and moved up for reuse during the climbing process, reducing material consumption; 5. Adapting to the characteristics of fourth-generation residential terrace construction: By zoning and lifting the scaffolding in stages, the unprotected construction state in the terrace area is avoided, improving construction efficiency and safety.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0016] This embodiment provides a double-climbing scaffold for the construction of fourth-generation residential terraces, including: The vertical main frame 1 is set along the outside of the building structure and serves as the main load-bearing frame of the entire climbing formwork; The wall-mounted support is installed on the vertical main frame 1 and is used to attach the vertical main frame 1 to the building structure; The lifting system is connected to the vertical main frame 1 and is used to drive the scaffold as a whole to rise and fall synchronously along the building structure.

[0017] Along the height direction on the vertical main frame 1, the following are respectively set: Upper climbing scaffold assembly 4: includes an upper platform load-bearing beam assembly and an upper operating platform mounted thereon; Lower climbing scaffold assembly 5: A frame structure with independent protection functions, including a lower platform load-bearing beam assembly, a lower operating platform, and protective components set around the lower operating platform.

[0018] The upper climbing frame assembly 4 and the lower climbing frame assembly 5 are set independently of each other and do not form a closed structure between them, so as to avoid the formation of a closed space that would cause inconvenience to construction.

[0019] Example 2: Installation of Fall Protection Structure like Figure 2 , Figure 3 As shown, a fall arrestor 6 is provided between the upper climbing scaffold assembly 4 and the lower climbing scaffold assembly 5. This fall arrestor 6 is used to limit abnormal downward displacement of the upper climbing scaffold assembly 4 relative to the lower climbing scaffold assembly 5.

[0020] Specifically, the fall protection structure 6 includes: Fall arrestor connector 6a: connected to the upper climbing frame assembly 4 and the vertical main frame 1 respectively; Guide limiter 6b: set along the vertical main frame 1, used to guide the fall arrestor 6 to move synchronously with the vertical main frame 1 during the lifting and lowering of the scaffold.

[0021] During the lifting process, the upper climbing frame assembly 4 is lifted as a whole under the drive of the lifting system, while the anti-fall structure 6 moves synchronously along the guide limit piece, thereby ensuring that the upper climbing frame will not fall abnormally relative to the lower climbing frame.

[0022] Example 3: Independent protective structure for the lower climbing scaffold like Figure 4 As shown, the lower climbing scaffold assembly 5 is a frame structure with independent protective functions. Its protective components may include at least one of protective uprights, guardrails, and protective netting.

[0023] In the terrace area, the lower climbing frame forms a complete protective enclosure structure through protective components, preventing construction workers or materials from falling, while also creating a local protective barrier for the terrace area.

[0024] Example 4: Staggered Layout and Space Truss Structure In this embodiment, the upper climbing frame assembly 4 and the lower climbing frame assembly 5 are arranged in a staggered manner in the vertical direction, which can avoid mutual interference between the two and improve the structural stability and construction space utilization.

[0025] The vertical main frame 1 is composed of uprights, horizontal bars and diagonal support components, and forms a multi-layer spatial truss structure at the positions corresponding to the upper climbing frame assembly 4 and the lower climbing frame assembly 5, thereby meeting the load-bearing and stability requirements of the overall protection of the upper layer and the local protection of the lower layer.

[0026] Example 5: Construction Method like Figure 5 As shown, this embodiment provides a construction method for a double-climbing scaffold used in the construction of fourth-generation residential terraces, specifically including the following steps: Step S1: Erection and initial attachment of the climbing scaffold Before the main structure is constructed, an upper climbing scaffold is erected on the outside of the main building to allow it to form an initial attachment to the building structure through attachment devices and anti-fall components.

[0027] That is, before the main structure is constructed, an upper climbing scaffold is erected on the outside of the main building. The upper climbing scaffold is an attached lifting scaffold structure. The climbing frame is reliably attached to the building structure through wall supports and fall arrestors, and is installed and adjusted to its initial height, enabling it to have overall protection and synchronous lifting capabilities.

[0028] Step S2: Lift the entire upper scaffold. Once the main structure has completed the pouring of one layer of concrete and reached the predetermined strength, the climbing frame is driven to lift the entire structure by one layer and re-establish attachment connections with the main structure.

[0029] That is, after the main structure has completed the concrete pouring of the first floor or the first standard floor and reached the predetermined strength, the lifting components and power equipment of the climbing formwork are started to lift the climbing formwork up one floor along the building structure as a whole. After the upgrade is completed, the wall-mounted device will be used to re-establish an attachment connection with the new floor main structure, forming a stable construction and protection state.

[0030] Step S3: Ground assembly of the lower scaffold After the upper climbing scaffold is raised and forms a gap of at least two floors with the main structure, a lower climbing scaffold with independent protective functions is assembled on the ground for each balcony or terrace area.

[0031] That is, after the upper climbing scaffold completes its first lift and forms a two-story gap with the main structure, the lower climbing scaffold is assembled independently on the ground for each cantilevered balcony or terrace area. The lower climbing frame is an attached lifting frame with independent protection function. Its structure does not form a closed enclosure with the upper climbing frame, but only establishes a connection with the corresponding balcony or structural part through the attachment device.

[0032] Step S4: Descend the climbing frame and lift in sections and in stages. While ensuring the upper climbing scaffold remains stably attached, the lower climbing scaffolds are lifted in sections and in stages according to the arrangement of balconies or terraces. After the lower climbing scaffold of one balcony is lifted and secured, the lifting of the lower climbing scaffold of the next balcony is carried out, and the lower climbing scaffolds do not interfere with each other during the lifting process.

[0033] Once the upper climbing scaffold is stably attached and continuously provides overall protection for the main facade, the lower climbing scaffolds are then lifted according to the arrangement of balconies or terraces. The lifting of each lower scaffold is carried out one balcony at a time. That is, after the lower scaffold of one balcony area is lifted and fixed, the lower scaffold of the next balcony is lifted, and the lower scaffolds do not interfere with each other during the lifting process.

[0034] Step S5: Continuous protection during construction During the construction of the main structure and balconies and terraces, the upper climbing scaffold provides overall protection for the building facade, while the lower climbing scaffold provides supplementary protection for the open balcony area, thus achieving continuous three-dimensional protection for the facade.

[0035] During the alternating lifting process of the upper and lower climbing frames, only the attachment devices and fall protection components are reused, and the rest of the main structure of the climbing frame is not dismantled or modified. The turnover of the attachment device and fall protection components includes the following steps: (a) Materials for attachment devices and fall arrestors are hoisted through the pre-reserved openings in the flaps at the climbing frame location; (b) When the concrete pouring is completed and the climbing formwork is ready to be lifted, the wall supports and fall protection components at the bottom shall be removed and packed together. (c) Using the manual hoisting channel set up inside the frame, the dismantled components are hoisted from the lower level to the current working level by means of rope or manual lifting; (d) Reinstall the attachment device and fall arrestor at the location of the upper structure for use in the next climbing operation.

[0036] During the construction of the double-climbing scaffold with coordinated protection, in the process of constructing the main structure and balconies / terraces: The climbing scaffold is always located outside the main structure, providing continuous and integrated protection for the building facade. The lower scaffolding provides supplementary protection for the open areas of each balcony. This achieves full-coverage, three-dimensional safety protection for the building facade, preventing unprotected construction in open areas.

[0037] Step S6: Removal and Sealing After all structural construction is completed, the upper and lower climbing scaffolds are dismantled according to the principle of "first erected, then dismantled" and "last erected, first dismantled," and the attachment holes are sealed.

[0038] That is, after the main structure and the staggered terraces and cantilevered balconies have been fully constructed, the upper climbing scaffold and each lower climbing scaffold will be dismantled in sequence according to the principle of first erecting and then dismantling, and the last erected and then dismantled. After demolition, the original attachment holes were sealed with cement mortar, and loose concrete areas were removed if necessary to ensure the safety and integrity of the main structure.

[0039] The attachment device and fall protection components are interchangeable. During the lifting process of the upper and lower climbing scaffolds, only the attachment devices and fall protection components are reused, specifically including: 1. Material hoisting: Materials for attachment devices and fall arrestors are hoisted through the pre-reserved openings on the flaps at the climbing frame location; 2. Demolition and Concentration: When the concrete pouring is completed and the climbing is in preparation, the bottom wall supports and fall protection components are removed and concentrated. 3. Manual hoisting: Using manual hoisting methods inside the frame, the dismantled attachment devices and fall protection components are hoisted from the lower level to the current working level; 4. Reinstallation: Reinstall the attachment device and fall arrestor components in the upper structure for continued use.

[0040] Through the above structural design and construction methods, the double climbing formwork system provided by this invention can effectively solve the problems of protection gaps, high safety risks, and low construction efficiency in the construction of fourth-generation residential terraces, achieve continuous three-dimensional protection of the building facade and terrace area, and has good construction operability and cost advantages.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
