Description

Technical Field

[0001] The present invention belongs to the technical field of bridge construction, and more specifically, relates to an assembled tower crown structure and an installation method. Background Art

[0002] Cable-stayed bridges and suspension bridges have excellent spanning capabilities and are built all over the world. Cable-stayed bridges are built by anchoring cables to carriers such as main beams and cable towers, while suspension bridges are built by anchoring cables to carriers such as cable towers and the ground to form a system that shares common loads. Cable towers are important load-bearing components that mainly bear axial pressure, bending moment and other loads. Therefore, reinforced concrete is often more economical when used as the main material. At the same time, due to the stress characteristics of flexible components such as cables and cables, the height of the cable tower as the anchor end is generally proportional to the span of the bridge. This feature makes the cable tower usually the tallest structure on a bridge or a road. The tower crown refers to the highest part of the cable tower, which usually has a landscape, shape or material that is different from other parts of the cable tower, so it is naturally easy to become the visual focus.

[0003] With the rapid development of my country's bridge industry in recent decades, the quality standards of bridge construction have gradually improved, and the requirements for bridge landscape effects have become increasingly higher. The tower crown, as the finishing touch of cable-stayed bridges, suspension bridges and other bridge types, requires special design in terms of shape and lighting effects. Depending on the span of the bridge, the height of the cable tower can reach hundreds of meters. Therefore, in addition to considering the landscape effect of the cable tower crown, the tower crown structure must also consider the convenience of construction and the structural safety under high-altitude strong wind loads.

[0004] For reinforced concrete cable towers, the existing tower crown structure is generally also a reinforced concrete structure. When carrying out reinforced concrete construction of the tower crown shape at high altitude, processes such as scaffolding erection, formwork fixing, steel bar binding, and concrete pouring all face potential safety risks, which also limits the design of the tower crown landscape effect to a certain extent. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the present invention provides an assembled tower crown structure and an installation method. By adopting the method of modular prefabrication and on-site assembly, the traditional reinforced concrete tower crown bracket erection, formwork fixing, steel bar binding and other processes are avoided. At the same time, the core tube only occupies a small amount of internal space at the top of the tower, and the rest can be used as a construction platform, which greatly reduces the potential safety risks of high-altitude tower crown construction. The core tube adopts a combined structure of steel shell and concrete core, which provides strong rigidity for the tower crown and ensures the structural safety of the tower crown under high-altitude strong wind loads. The tower crown facade adopts different types of facades to meet the needs of various landscape designs. Through the selection of translucent facades, landscape lighting devices can be arranged inside the tower crown to achieve self-luminescence on the side of the tower crown, further enhancing the landscape effect of the tower crown.

[0016] Furthermore, the first standard facade, the second standard facade, and the third standard facade are all fixedly connected to standard facade connecting parts by bolts.

[0017] Furthermore, the top cover, core tube inner shell, core tube outer shell and diaphragm are prefabricated and welded into a whole in the factory, and hoisted as a whole to the top of the cable tower during construction. The steel columns and standard facade connectors are prefabricated and welded into a whole in the factory to form a facade support module.

[0018] According to a second aspect of the present invention, there is provided a method for installing a prefabricated tower crown structure, comprising the following steps:

[0019] S100: prefabricate all steel components in the factory, weld the steel top cover, the inner shell of the core tube, the outer shell of the core tube, and the diaphragm to form an integral core tube module, weld the steel columns and the standard facade connectors as a whole to form a facade support module, make the first standard facade, the second standard facade, the third standard facade, and the special-shaped facade module, reserve bolt holes on the inside, and make the light-transmitting facade and its light-transmitting facade connectors;

[0025] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0026] 1. The assembled tower crown structure of the present invention adopts the method of modular prefabrication and on-site assembly, avoiding the processes of traditional reinforced concrete tower crown bracket erection, formwork fixing, steel bar binding, etc., which not only greatly shortens the construction period, but also significantly improves the construction efficiency. Its core tube is exquisitely designed, occupying only the extremely limited internal space at the top of the tower, and the remaining spacious area can be flexibly used as a construction platform, providing a safer and more convenient working environment for construction personnel, thereby greatly reducing the potential safety risks in the construction process of high-altitude tower crowns and ensuring construction quality and personnel safety.

[0027] 2. The assembled tower crown structure of the present invention adopts a combined structure of a steel shell and a concrete core composed of an inner shell of a core tube, an outer shell of a core tube and a concrete core. The synergistic effect of the steel shell and the concrete core provides the tower crown with strong rigidity. Moreover, through the combination of the high strength of steel and the good compressive resistance of concrete, the structural safety and stability of the tower crown under high-altitude strong wind loads are improved, thereby ensuring the structural safety of the tower crown under high-altitude strong wind loads.

[0028] 3. The assembled tower crown structure of the present invention adopts different facade structure designs, so that it can easily adapt to and integrate into various landscape design needs, and integrate with the urban environment and architectural style. By selecting facade materials with excellent light transmittance, it not only creates good natural lighting conditions for the interior of the tower crown, but also enables various landscape lighting devices to be cleverly arranged inside the tower crown. When night falls, these carefully arranged lighting devices will light up the side of the tower crown to achieve a self-luminous effect, adding a touch of dazzling brilliance to the city's night view, further sublimating the landscape value of the tower crown, and making it a beautiful landscape on the city skyline.

[0037] like Figure 1-2As shown, an embodiment of the present invention provides an assembled tower crown structure, including a core tube module, a facade support module, and a facade module. The core tube module is arranged in the middle of the top of the cable tower, and includes a steel top cover 1 arranged at the top of the cable tower, a core tube inner shell 2 is fixedly installed between the steel top cover 1 and the cable tower, a core tube outer shell 3 fixedly connected to the steel top cover 1 and the cable tower is arranged outside the core tube inner shell 2, a concrete core 4 is arranged between the core tube inner shell 2 and the core tube outer shell 3, and the three together constitute a steel shell-concrete core combined structure, which provides strong rigidity for the tower crown; the facade support module is arranged on the outside of the core tube module, and includes a plurality of steel columns 6 arranged between the cable tower and the steel top cover 1, and a plurality of standard facade connectors 7 for fixedly connecting the facade module are fixedly installed on the outside of the steel columns 6; the facade module is arranged on the outside of the facade support module, and includes a first standard facade 8, a second standard facade 9, a third standard facade 10, a special-shaped facade 11 and a light-transmitting facade 12. As the central support part of the assembled tower crown structure, the core tube module plays a key role in bearing and stabilizing. Its interior includes steel top cover, core tube inner shell, core tube outer shell, concrete core and diaphragm. These components work together to ensure that the tower crown structure can remain stable when subjected to various loads. The various components of the core tube module are prefabricated and welded into a whole in the factory, and then hoisted as a whole at the construction site. This factory prefabrication and on-site assembly construction method greatly improves construction efficiency and shortens construction period. After pouring the concrete core, the core tube module becomes a platform for subsequent construction. This facilitates the installation of the subsequent facade support module and facade module; the facade support module is mainly composed of steel columns and module connectors, which together provide solid support for the facade module. As the main load-bearing component, the steel column is connected to the core tube module and the facade module through the module connector to ensure the stability of the entire structure. The steel columns and module connectors of the facade support module are prefabricated and welded into a whole in the factory, and then hoisted to the construction site one by one. This design makes the facade support module highly flexible and can be adjusted and optimized according to actual needs. The facade support module improves the wind and earthquake resistance of the assembled tower crown structure through reasonable structural design and material selection. Under extreme weather conditions such as strong winds or earthquakes, the facade support module can effectively absorb and disperse the load and protect the safety of the entire structure; the facade module is an important part of the assembled tower crown structure, and its design and installation directly affect the appearance of the entire structure. By selecting appropriate materials, colors, and textures, a unique and beautiful architectural appearance can be created. The facade module is not only aesthetically pleasing, but also functional. For example, the light-transmitting module can be made of materials such as transparent polycarbonate, which can not only keep the room bright and ventilated, but also resist the erosion of natural factors such as wind and rain. The facade module is prefabricated in the factory and assembled on site, making subsequent maintenance and replacement more convenient.When a module needs to be repaired or replaced, it can be removed and replaced individually without making large-scale changes to the entire structure.

[0038] like Figure 1-2 As shown, the core tube module includes a steel top cover 1 arranged on the top of the cable tower, with holes in the middle for facilitating workers' construction and later maintenance, and circumferential and radial stiffening plates at the bottom for increasing the bearing capacity of the steel top cover 1, a core tube inner shell 2 is fixedly installed between the steel top cover 1 and the cable tower, a core tube outer shell 3 fixedly connected to the steel top cover 1 and the cable tower is arranged on the outside of the core tube inner shell 2, the core tube inner shell 2 and the core tube outer shell 3 are provided with holes in the same direction for facilitating workers' construction and later maintenance, a concrete core 4 is arranged between the core tube inner shell 2 and the core tube outer shell 3, and the three together constitute a combined structure of a steel shell-concrete core, a plurality of diaphragms 5 are fixedly installed on the outside of the core tube outer shell 3, the top cover 1, the core tube inner shell 2, the core tube outer shell 3 and the diaphragm 5 are prefabricated and welded into a whole in the factory, and are hoisted as a whole to the top of the cable tower during construction, and then the concrete core 4 is poured to form the skeleton of the tower crown and a platform for subsequent construction, providing a safe working surface for subsequent construction. The core tube module is mainly composed of steel. The high strength and rigidity of the steel enable the entire module to withstand large loads and deformations, ensuring the stability of the tower crown structure. The core tube module, as the skeleton of the tower crown, provides structural stability at the top of the cable tower and enhances the wind and earthquake resistance of the entire cable tower. The concrete core 4 is arranged between the core tube inner shell 2 and the core tube outer shell 3. As a filling material, it not only increases the weight of the module, but also improves its compressive strength and overall stability. Multiple diaphragms 5 are fixedly installed on the outside of the core tube outer shell 3, playing the role of horizontal support, further enhancing the lateral force resistance and overall stability of the core tube module. After the concrete core is poured, the core tube module forms a stable platform, providing a safe working surface for subsequent construction.

[0039] like Figure 1-2As shown, the facade support module includes a plurality of steel columns 6 arranged between the cable tower and the steel top cover 1. The top of the steel column 6 is connected to the steel top cover 1 by bolts, and the bottom is connected by anchor bolts, which ensures a stable connection with the tower crown structure, not only improving the overall stability of the structure, but also effectively dispersing the load and enhancing the wind resistance. A plurality of standard facade connectors 7 are fixedly installed on the outside of the steel column 6, and the standard facade connector 7 is used to fix the facade module; the top of the steel column 6 is connected to the steel top cover 1 by bolts, and the bottom is connected by anchor bolts. This connection method It is both strong and easy to disassemble, which improves the safety and flexibility of construction. Since the module connectors and steel columns are welded as a whole in the factory, they can be quickly hoisted, which improves construction efficiency and reduces on-site operation time, reducing construction difficulty and cost. The prefabricated facade support modules reduce on-site welding work, reduce construction risks, and improve construction quality. In addition to providing support, the facade support modules can also serve as fixing points for installing facade modules, as well as channels or platforms for subsequent maintenance and inspection. This versatility makes the tower crown structure more flexible and practical.

The light-transmitting facade 12 is fixed by clamping the groove on the light-transmitting facade connector 13 to ensure the stability and firmness of the light-transmitting facade 12. The light-transmitting facade 12 adopts a light-transmitting The special-shaped facade 11 is L-shaped, with multiple horizontal and vertical stiffening plates on the inside and multiple bolt holes on the bottom, which are fixedly connected to the third standard facade 10 by bolts; a multi-level facade structure is formed by the combination of the first standard facade 8, the second standard facade 9, the third standard facade 10, the light-transmitting facade 12 and the special-shaped facade 11, which enhances the overall stability and wind pressure resistance. The first standard facade 8, the second standard facade 9, the third standard facade 10 and the special-shaped facade 11 are all fixedly connected by bolts.
