Description

Technical Field

[0001] This utility model relates to the field of building isolation and protection, specifically a temporary support system for a large-span spherical roof with intersecting arc-shaped curved ribs. Background Technology

[0002] In the field of modern building construction, the large-span spherical roof with intersecting curved ribs and beams has extremely high requirements for the temporary support system during construction due to its unique shape and complex structural characteristics.

[0003] like Figure 1 , Figure 2 A building structure employing a reinforced concrete frame-shear wall system has a roof structure consisting of intersecting curved beams and slabs. Loads are transferred through a parallelogram-shaped ring beam at 16.50 meters and 36 structural columns below. This complex roof structure, including intersecting curved ribs and slabs, cannot be directly transferred to the completed ring beams and columns due to the design of the construction sequence, as the loads from reinforcement, formwork, and concrete work cannot be directly transferred. Therefore, a temporary support system is needed to bear this load and ensure the smooth progress of construction. This temporary support system must not only possess sufficient load-bearing capacity and stability but also be able to adapt to the complex characteristics of the roof, such as its high span and intersecting curved surfaces.

[0004] Currently, various support systems existing in the fields of building construction and bridges, such as modular scaffolding and formwork trusses, have shown limitations when applied to this project. While modular scaffolding is lightweight and easy to assemble, its span and height are limited, and it is difficult to adapt to complex structures such as circular ring beams on roofs. Although formwork trusses have strong load-bearing capacity, their construction is complex and costly, and they also cannot fully meet the specific requirements of this project.

[0005] In particular, the roof of this project is a high-altitude, large-span, intersecting, curved, ribbed spherical structure with varying beam cross-sectional dimensions and curvature. The highest point of the concrete roof is 49.27 meters above the ground foundation, with a span of 130 meters. These structural characteristics make traditional support systems inadequate for construction needs, resulting in enormous material consumption, significant erection difficulties, and higher requirements for the overall height-to-width ratio and reinforcement measures of the scaffolding, thus affecting the overall safety and stability of the construction.

[0006] Therefore, given the characteristics and needs of this project, there is an urgent need for a new type of efficient and stable temporary support system to solve the support problem of a large-span spherical roof with intersecting curved ribs during construction. Utility Model Content

[0007] The purpose of this invention is to overcome the aforementioned shortcomings and propose a highly efficient combined support system for a large-span spherical roof with intersecting curved ribbed beams. This temporary support system features strong load-bearing capacity, good stability, strong adaptability, convenient construction, and economic rationality, while also ensuring the smooth progress of construction and the safety and stability of the roof structure.

[0008] To achieve the above objectives, this utility model is implemented as follows:

[0009] A temporary support system for a large-span spherical roof with intersecting curved ribbed beams, including...

[0010] Functional frame structure: includes multiple high-strength steel pipe columns, sturdily connected steel pipe horizontal bars and steel pipe diagonal bars. The steel pipe columns are firmly fixed to the ground or substructure through specially designed connecting ends, forming a basic frame supporting the roof. The functional frame structure is used to provide load-bearing capacity and its position and size can be flexibly adjusted according to construction needs to adapt to the support requirements of the curvature and curved surfaces of different areas of the roof.

[0011] Enhanced top truss: Installed on top of the functional frame structure, it is composed of H-beams that have been structurally designed and selected. It is used to enhance the overall load-bearing capacity and stability of the functional frame structure and effectively prevent and resist various lateral and vertical loads that occur during construction.

[0012] Modular disc-lock support system: Installed on the functional frame structure and top truss, it consists of standardized disc-lock uprights, horizontal bars and diagonal bars tightly connected by reliable fasteners to form a matrix-distributed full-span frame structure, used to bear the self-weight of the upper beams and slabs and various construction loads, ensuring safety and stability during construction.

[0013] The temporary support system forms a stable support foundation through a five-ring circumferentially arranged functional frame structure. The support columns of each ring are arranged according to a predetermined spacing and layout to ensure the uniformity and stability of the support.

[0014] The top truss is divided into two layouts: circumferential trusses and radial trusses. The circumferential trusses are arranged along the periphery of the functional frame structure and connected to the functional frame structure to enhance the circumferential stiffness of the entire functional frame structure in the horizontal direction. The radial trusses extend outward from the central area of ​​the functional frame structure and form a stable connection with the circumferential trusses and the functional frame structure, effectively transferring loads and enhancing the stability of the supporting structure in the radial direction.

[0015] Furthermore, the steel pipe columns, steel pipe crossbars, and steel pipe diagonal bars of the frame structure are securely connected through a specific connection method to form a triangular support configuration with enhanced stability; and the top truss is made of selected H-beams to further improve the rigidity of the overall structure; at the same time, the disc buckle support system uses standardized components and achieves quick and reliable assembly and disassembly through a unique fastening method.

[0016] Furthermore, in the temporary support system of the aforementioned large-span spherical roof with intersecting curved ribs, the steel pipe columns, steel pipe crossbars, and steel pipe diagonal bars of the frame structure are securely connected by welding or bolting to form a stable triangular support structure.

[0017] Furthermore, in the temporary support system of the aforementioned large-span spherical roof with intersecting curved ribs, the H-beams of the top truss are connected by welding or high-strength bolts to ensure the overall rigidity and stability of the truss structure.

[0018] Furthermore, the temporary support system for the aforementioned large-span spherical roof with intersecting curved ribs, including the disc-lock support system, consists of standardized components such as the disc-lock uprights, horizontal bars, and diagonal bars. These components are connected quickly and reliably via fasteners, facilitating on-site assembly and disassembly.

[0019] Furthermore, the temporary support system for the aforementioned large-span spherical roof with intersecting curved ribs also includes additional connectors to enhance overall stability. These additional connectors are located between the frame structure, the top truss, and the disc-lock support system, and are fixedly connected to each component by welding or bolting.

[0020] Furthermore, the temporary support system for the aforementioned large-span spherical roof with intersecting curved ribs has an adjustment device at the bottom of the steel pipe columns of the formwork structure, which is used to adjust the height and level of the formwork structure to adapt to the needs of different construction sites.

[0021] This utility model adopts the above design and has the following significant features:

[0022] 1. Functional frame structure:

[0023] The steel pipe columns are securely and adjustablely fixed to the ground or substructure via specially designed connecting ends, forming a solid foundation framework supporting the roof. This design allows the formwork structure to be flexibly adjusted in position and size according to construction needs, adapting to the curvature and surface variations of different areas of the roof;

[0024] The steel pipe columns, steel pipe crossbars, and steel pipe diagonal bars are firmly connected by welding or high-strength bolts, forming a triangular support structure with extremely high stability, which further enhances the overall structure's resistance to lateral forces and overturning.

[0025] 2. Regarding the top truss:

[0026] Constructed from H-beams using rigorous structural design and selection, this structure ensures high strength and rigidity in practical applications. This not only enhances the overall load-bearing capacity and stability of the functional formwork structure but also effectively prevents and resists various lateral and vertical loads that may occur during construction, such as wind loads and construction equipment loads.

[0027] 3. Modular disc buckle support system:

[0028] The support system consists of standardized disc-lock uprights, horizontal bars, and diagonal bars, which are installed on the functional frame structure and the top truss to form a matrix-distributed full-span frame structure.

[0029] These components achieve quick and tight connections through reliable fasteners, greatly improving construction efficiency and ease of on-site assembly.

[0030] The modular disc-locking support system can bear the self-weight of the upper beams and slabs as well as various construction loads, ensuring safety and stability during construction, while providing a safe working platform for construction personnel.

[0031] 4. Regarding standardized components and additional connectors:

[0032] This combined support system uses a large number of standardized components, such as H-beams and disc-lock uprights. The standardized production of these components not only reduces costs but also improves construction speed and on-site management efficiency.

[0033] To further enhance overall stability, this combined support system also incorporates additional connectors between the frame structure, the top truss, and the modular support system. These connectors are fixed to the various components via welding or bolting, forming a more robust overall structure. Attached Figure Description
