Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a combined scaffolding based on attached climbing formwork and its construction method. Background Technology

[0002] With the continuous development of the construction industry and the increasing scarcity of land resources, the number of (super)high-rise buildings is increasing, and the application of integrated attached climbing scaffolding in construction is becoming more and more widespread. However, when the main structure of a (super)high-rise building reaches the rooftop ancillary level, the roof structure of the ancillary level tends to shrink inwards, making attached climbing scaffolding unsuitable for the structural changes of the ancillary level, thus causing difficulties in construction. Climbing scaffolding can only be used to climb to the standard floor below the rooftop ancillary level. When constructing the rooftop ancillary level, a new cantilever scaffolding is erected, or a specially designed climbing scaffolding system with a split lifting method is used to meet the needs of the rooftop and its ancillary construction. This brings inconvenience and challenges to the main construction of (super)high-rise buildings, limiting the project's economic efficiency, safety, and schedule.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a combined scaffolding based on attached climbing formwork and its construction method are provided to solve the problem of extended construction period and high construction cost caused by structural changes in the rooftop ancillary floors of super high-rise main structures, which necessitate the use of re-erecting cantilevered scaffolds or specially designed climbing formwork with a split lifting method to meet the needs of rooftop and ancillary construction.

[0005] To achieve the above objectives, a combined scaffolding based on attached climbing formwork is provided. The building structure includes a main structure and an auxiliary structure, wherein the auxiliary structure is formed on top of the main structure. The combined scaffolding based on attached climbing formwork includes:

[0006] An attached climbing scaffold is installed on the outer side of the exterior wall of the main structure.

[0007] Transformer support, on which the exterior wall of the main structure is installed;

[0008] The upright includes multiple inner pipes and multiple outer pipes. The outer pipes are erected on the operating platform of the attached climbing scaffold, and the inner pipes are erected on the conversion support. The inner pipes are arranged between the outer pipes and the outer wall of the main structure.

[0009] A crossbar is connected between multiple inner pipes, between multiple outer pipes, and between an inner pipe and an outer pipe.

[0010] Multiple wall ties are arranged vertically, and the multiple wall ties are installed on the upright. The lower wall ties of the upright are connected to the outer wall of the main structure, and the upper wall ties of the upright are connected to the outer wall of the auxiliary structure.

[0011] Furthermore, the conversion support includes:

[0012] A support beam has a fixed end and a cantilever end. The fixed end is connected to an end plate, which is attached to the outer wall of the main structure. The cantilever end is vertically provided with a plug rod, which is detachably inserted into the lower end of the inner pipe.

[0013] A tie rod is inserted into the outer wall of the main structure, and an end plate is installed at one end of the tie rod.

[0014] Furthermore, the supporting beam includes an upper flange, a lower flange disposed opposite to the upper flange, and a web, the web being connected between the upper flange and the lower flange, and the end plate being connected to one end of the upper flange, the lower flange, and the web.

[0015] Furthermore, the outer diameter of the end plate is larger than the outer diameter of the supporting beam.

[0016] Furthermore, the end plate has two first through holes, the number of tie rods of the conversion support is at least two, a second through hole is formed in the outer wall of the main structure, the second through hole is coaxially arranged with the first through hole, the tie rod passes through the first through hole and the second through hole, and a retaining member is detachably installed at both ends of the tie rod, the retaining members at both ends of the tie rod press against the outer side of the end plate and the inner side of the outer wall of the main structure, respectively.

[0017] Furthermore, the end of the lower wall tie rod of the upright is connected to the upright of the attached climbing scaffold.

[0018] This invention provides a construction method for a combined scaffolding based on an attached climbing formwork, comprising the following steps:

[0019] The attached climbing scaffold is raised to the top of the main structure, so that the attached climbing scaffold is installed on the outside of the outer wall of the main structure;

[0020] The main structure is equipped with external wall conversion supports;

[0023] Multiple wall ties are installed on the upright. The multiple wall ties are arranged vertically. The lower wall ties of the upright are connected to the outer wall of the main structure, and the upper wall ties of the upright are connected to the outer wall of the auxiliary structure.

[0024] The beneficial effects of this invention are as follows: The combined scaffolding based on attached climbing formwork utilizes a combination of transition supports and attached climbing scaffolding. When the climbing formwork cannot match the changes in the outer contour of the structure when it is raised to the roof of the auxiliary structural layer, the combined scaffolding based on attached climbing formwork plays an important role in transferring the load, perfectly conforming to the changes in the outer contour of the roof structure and solving the problem of limited climbing formwork elevation. With the combination of transition supports and climbing formwork, the attached climbing formwork can climb to the top in one go, and the operating platform of the attached climbing formwork can cover the entire roof auxiliary structural layer construction, eliminating the need for extensive reconstruction of cantilevered scaffolding for the auxiliary structural layer.

The structure is safe and reliable, and construction is convenient and efficient. Attached Figure Description

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 4 As shown, the present invention provides a combined scaffolding based on an attached climbing scaffold, including: an attached climbing scaffold 1, a conversion support 2, uprights, horizontal bars 4, and multiple wall ties 5.

[0033] The attached climbing scaffold 1 is installed on the outside of the outer wall of the main structure 6.

[0034] See also Figure 1 and Figure 2 As shown, the building structure includes a main structure 6 and an auxiliary structure 7. The auxiliary structure 7 is formed on top of the main structure 6. The top of the main structure extends along the surface direction of the roof panel to form a cantilever slab. However, the cantilever slab is not continuously arranged, which causes the attached climbing formwork to be unable to match the changes in the outer contour of the auxiliary structure when it is lifted to the auxiliary structure.

[0035] The transfer support 2 is installed on the outer side of the outer wall of the main structure 6. A gap is formed between the attached climbing scaffold 1 and the outer wall of the main structure 6.

[0036] The upright includes multiple inner pipes 31 and multiple outer pipes 32. The multiple inner pipes 31 are arranged along the circumferential direction of the building structure.

[0037] The external pipe 32 is vertically installed on the operating platform 11 of the attached climbing scaffold 1. The internal pipe 31 is vertically installed on the conversion support 2. The internal pipe 31 is located between the external pipe 32 and the outer wall of the main structure 6.

[0038] A crossbar 4 connects multiple inner pipes 31. A crossbar 4 connects multiple outer pipes 32. A crossbar 4 connects the inner pipes 31 and the outer pipes 32.

[0039] Multiple wall ties 5 are installed vertically. These wall ties are mounted on the uprights. The lower wall ties 5 of the uprights are connected to the exterior wall of the main structure 6. The upper wall ties 5 of the uprights are connected to the exterior wall of the auxiliary structure 7.

[0040] As a preferred embodiment, the conversion support 2 includes: a support beam and a tie rod 22.

[0041] The supporting beam has a fixed end and a cantilever end. The fixed end is connected to an end plate 24. The end plate 24 is attached to the outer wall of the main structure 6. The cantilever end is vertically provided with a connecting rod. The connecting rod is detachably inserted into the lower end of the inner pipe 31.

[0042] Tie rod 22 is inserted into the outer wall of the main structure 6. End plate 24 is installed at one end of tie rod 22.

[0043] Specifically, the supporting beam includes an upper flange 21, a lower flange 22, and a web 23. The upper flange 21 and the lower flange 22 are arranged opposite to each other. The web 23 connects the upper flange 21 and the lower flange 22. An end plate 24 connects to one end of the upper flange 21, the lower flange 22, and the web 23.

[0044] In this embodiment, participants Figure 4 As shown, the outer diameter of the end plate 24 is larger than the outer diameter of the supporting beam.

[0045] The end plate 24 has two first through holes. The number of tie rods 22 in the transition support 2 is at least two. A second through hole is formed in the outer wall of the main structure 6. The second through hole is coaxial with the first through hole. The tie rods 22 pass through the first and second through holes. Each end of the tie rod 22 is detachably fitted with a retaining member 221. The retaining members 221 at both ends of the tie rod 22 press against the outer side of the end plate 24 and the inner side of the outer wall of the main structure 6, respectively.

[0046] The end of the lower wall tie 5 of the upright is connected to the upright of the attached climbing scaffold 1 away from the outer wall.

[0047] This invention provides a construction method for a combined scaffolding based on an attached climbing formwork, comprising the following steps:

[0048] S1: Climb the attached climbing frame 1 to the top of the main structure 6, so that the attached climbing frame 1 is installed on the outside of the outer wall of the main structure 6.

[0049] S2: The external wall of the main structure 6 is fitted with a conversion support 2.

[0050] S3: The multiple outer pipes 32 of the upright are erected on the operating platform of the attached climbing frame 1, and the multiple inner pipes 31 of the upright are erected on the conversion support 2. The inner pipes 31 are set between the outer pipes 32 and the outer wall of the main structure 6.

[0051] S4: Connect crossbars 4 between multiple inner pipes 31, between multiple outer pipes 32, and between inner pipes 31 and outer pipes 32 respectively.

[0052] S5: Install multiple wall ties on the upright. The multiple wall ties 5 are arranged vertically. The lower wall ties 5 of the upright are connected to the outer wall of the main structure 6, and the upper wall ties 5 of the upright are connected to the outer wall of the auxiliary structure 7.

[0053] This invention relates to a combined scaffolding system based on attached climbing scaffolding. By combining transition supports with the attached climbing scaffolding, this system plays a crucial role in transferring load-bearing capacity when the climbing scaffolding cannot match the changing outer contours of the roof structure during its ascent to the auxiliary structural layer. It perfectly conforms to the changing roof structure contours and solves the problem of limited climbing scaffolding ascent. With the transition supports and climbing scaffolding working together, the attached climbing scaffolding can ascend to the top in one go. The operating platform of the attached climbing scaffolding can cover the entire roof auxiliary structural layer construction, eliminating the need for extensive reconstruction of cantilevered scaffolding for the auxiliary structural layer.

[0054] The combined scaffolding based on attached climbing formwork of the present invention can quickly and effectively complete the transformation of the outline of (super) high-rise roof structure, providing the landing point of the external scaffolding uprights and the conversion of load-bearing capacity with the climbing formwork construction platform. The structure is safe and reliable, and the construction is convenient and efficient.

[0055] The modular scaffolding based on attached climbing formwork of this invention is structurally safe and can be prefabricated in a factory and reused repeatedly. Compared with the traditional method of dismantling the climbing formwork and then erecting a cantilevered scaffold or a split-lift climbing formwork, it saves more working time and construction costs.

[0056] Traditional climbing scaffolding construction, when reaching the roof's auxiliary layer, is limited by its own structural outline, making it unable to perfectly match the auxiliary layer's shape, thus failing to effectively protect the auxiliary layer structure during construction. This invention, a combined scaffolding system based on attached climbing scaffolding, optimizes the operating platform of the climbing scaffolding by extending it upwards and inwards to areas where the structure's outline changes. This allows for the use of the operating platform in areas and spaces where the top of the climbing scaffolding could not originally fit against the auxiliary layer structure, providing protection for the lives of construction workers and providing a platform for their work.

[0057] The modular scaffolding based on attached climbing scaffolding of this invention mainly uses the climbing scaffolding working platform and the conversion support as the footing points of the auxiliary layer of the outer scaffolding, which serves to convert the load-bearing structure. The inner uprights of the auxiliary layer of the outer scaffolding rest on the tool-type short-limb steel load-bearing cantilever frame, and the outer uprights of the outer scaffolding rest on the climbing scaffolding working platform. The upper part uses steel pipes (diameter 48mm, wall thickness 3.0mm), fasteners, and steel mesh panels to form the outer scaffolding and safety protection measures, and anti-overturning and reinforcement measures are implemented for the climbing scaffolding modular structure, so that the conversion support can better serve the climbing scaffolding, and its connection with the climbing scaffolding modular structure is more reliable and stable, and safety is guaranteed.

[0058] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
