Description

Technical Field

[0001] This invention belongs to the field of bridge construction technology, and more specifically, relates to a prefabricated tower crown structure and its installation method. Background Technology

[0002] Cable-stayed bridges and suspension bridges possess excellent spanning capabilities and are built worldwide. Cable-stayed bridges anchor cables to the main girder, pylons, and other supporting structures, while suspension bridges anchor cables to pylons, the ground, and other supporting structures, forming a shared load-bearing system. Pylons, as crucial load-bearing components, primarily withstand axial compression and bending moments; therefore, using reinforced concrete as the main material is often more economical. Furthermore, due to the load-bearing characteristics of flexible components like cables, the height of the pylon, as the anchoring end, is generally proportional to the bridge span. This characteristic makes the pylon usually the tallest structure on a bridge or road, and the pylon crown, referring to the highest part of the pylon, often has a distinctive appearance, shape, or material that sets it apart from the rest of the pylon, naturally becoming a visual focal point.

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

[0004] For reinforced concrete cable towers, the existing tower crown structure is generally also a reinforced concrete structure. When constructing the reinforced concrete tower crown shape at high altitude, the processes of scaffolding erection, formwork fixing, rebar binding, and concrete pouring all face potential safety risks, which also limit the design of the tower crown landscape effect to a certain extent. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a prefabricated tower crown structure and installation method. By adopting modular prefabrication and on-site assembly, it avoids the traditional processes of erecting reinforced concrete tower crown supports, fixing formwork, and binding reinforcing bars. Furthermore, the core tube occupies only a small portion of the internal space at the top of the tower, with the remainder serving as a construction platform, significantly reducing the potential safety risks of high-altitude tower crown construction. The core tube employs a steel shell-concrete core composite structure, providing the tower crown with strong rigidity and ensuring its structural safety under high-altitude strong wind loads. The tower crown's exterior facade can adapt to various landscape design requirements by employing different types of facades. The selection of translucent facades allows for the installation of landscape lighting devices inside the tower crown, achieving self-illumination on the sides and further enhancing the tower crown's aesthetic appeal.

[0006] To achieve the above objectives, according to one aspect of the present invention, a prefabricated tower crown structure is provided, including a core tube module disposed in the middle of the top of the tower, an outer facade support module disposed outside the core tube module, and an outer facade module disposed outside the outer facade support module.

[0007] The core tube module includes a steel top cover located at the top of the cable tower. A core tube inner shell is fixedly installed between the steel top cover and the cable tower. A core tube outer shell is fixedly connected to the steel top cover and the cable tower outside the core tube inner shell. A concrete core is provided between the core tube inner shell and the core tube outer shell. Multiple transverse partitions are fixedly installed on the outside of the core tube outer shell.

[0008] The facade support module includes multiple steel columns located between the cable tower and the steel roof, and multiple standard facade connectors are fixedly installed on the outside of the steel columns;

[0009] The facade module includes a first standard facade located at the top of the tower, a light-transmitting facade at the top of the first standard facade, a second standard facade at the top of the light-transmitting facade, a third standard facade at the top of the second standard facade, an irregular facade between the third standard facade and the steel roof, and a light-transmitting facade connector between the first standard facade and the light-transmitting facade, and between the light-transmitting facade and the second standard facade.

[0010] Furthermore, the first standard facade, the second standard facade, and the third standard facade are all provided with multiple horizontal and vertical stiffening plates on their inner sides. The stiffening plates are fixedly connected to steel plates, and the steel plates are provided with multiple bolt holes.

[0011] Furthermore, the irregular facade is L-shaped, with multiple horizontal and vertical stiffening plates on the inner side, and bolt holes for fixed installation at the bottom.

[0012] Furthermore, the steel top cover has a hole in the middle for easy construction and maintenance, and circumferential and radial stiffening plates at the bottom to increase load-bearing capacity.

[0013] Furthermore, the inner shell and outer shell of the core tube are provided with holes in the same direction to facilitate construction and subsequent maintenance.

[0014] Furthermore, the light-transmitting facade connector has a groove along its length on the outer side for fixing the light-transmitting facade, and multiple bolt holes on the inner side, which are fixedly connected to the top of the first standard facade and the bottom of the second standard facade by bolts.

[0015] Furthermore, the translucent facade is made of materials including but not limited to transparent polycarbonate, PMMA board, and glass.

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

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

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

[0019] S100: All steel components are prefabricated in the factory. The steel top cover, inner shell of the core tube, outer shell of the core tube, and diaphragm are welded together to form an integral core tube module. The steel columns are welded together with the standard facade connectors to form an exterior facade support module. The first standard facade, the second standard facade, the third standard facade, and the irregular facade are made, and bolt holes are reserved on the inside. The light-transmitting facade and its light-transmitting facade connectors are made.

[0020] S200: Transport the prefabricated core tube module, facade support module, and facade module to the cable tower construction site;

[0021] S300: Use lifting equipment to hoist the core tube module frame as a whole to the top of the tower, and ensure its position is accurate and stable. Pour concrete core into the core tube module frame. After the concrete solidifies, it forms the frame of the tower crown and becomes the platform for subsequent construction.

[0022] S400: Install the steel columns one by one, and use bolts to fix the top of the columns to the steel top cover. Use anchor bolts to fix the bottom of the columns to the top of the tower. After installation, check whether the connection is secure.

[0023] S500: The first, second, and third standard facades are hoisted one by one and fixed to the standard facade connectors with bolts. The irregular facade is hoisted and fixed to the third standard facade with bolts. The light-transmitting facade is fixed between the first and second standard facades with light-transmitting facade connectors to ensure that the position of the light-transmitting module is accurate and the fixation is firm.

[0024] S600: Conduct a comprehensive inspection of all components of the prefabricated tower crown structure to ensure that all components are firmly connected, accurately positioned, and undamaged, and to ensure that they meet the design requirements and functional requirements.

[0025] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0026] 1. The prefabricated tower crown structure of the present invention, by adopting modular prefabrication and on-site assembly, avoids the traditional reinforced concrete tower crown support erection, formwork fixing, and rebar binding processes. This not only significantly shortens the construction cycle but also significantly improves construction efficiency. Its core tube design is ingenious, occupying only the extremely limited internal space at the top of the tower, while the remaining spacious area can be flexibly used as a construction platform, providing a safer and more convenient working environment for construction personnel. This greatly reduces the potential safety risks during the construction of the high-altitude tower crown and ensures construction quality and personnel safety.

[0027] 2. The prefabricated tower crown structure of the present invention adopts a steel shell-concrete core composite structure composed of a core inner shell, a core outer shell, and a concrete core. The synergistic effect of the steel shell and the concrete core provides the tower crown with strong rigidity. Moreover, the combination of the high strength of steel and the good compressive strength of concrete improves the structural safety and stability of the tower crown under high-altitude strong wind loads, thus ensuring the structural safety of the tower crown under high-altitude strong wind loads.

[0028] 3. The prefabricated tower crown structure of the present invention, through the adoption of different facade structure designs, can easily adapt to and integrate into various landscape design needs, blending with the urban environment and architectural style. By selecting facade materials with excellent light transmission performance, it not only creates good natural lighting conditions for the interior of the tower crown, but also allows for the clever placement of various landscape lighting devices inside the tower crown. When night falls, these carefully arranged lighting devices will illuminate the sides of the tower crown, achieving a self-illuminating effect, adding a dazzling touch to the urban night scene, further enhancing the landscape value of the tower crown, and making it a beautiful scenic line on the urban skyline.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] In this patent, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0037] like Figure 1-2As shown, this embodiment of the invention provides a prefabricated tower crown structure, including a core tube module, an outer facade support module, and an outer facade module. The core tube module is located at the middle of the top of the tower and includes a steel top cover 1 located at the top of the tower. A core tube inner shell 2 is fixedly installed between the steel top cover 1 and the tower. A core tube outer shell 3 is fixedly connected to the steel top cover 1 and the tower outside the core tube inner shell 2. A concrete core 4 is provided between the core tube inner shell 2 and the core tube outer shell 3. The three together form a steel shell-concrete core composite structure, providing strong rigidity for the tower crown. The outer facade support module is located outside the core tube module and includes multiple steel columns 6 located between the tower and the steel top cover 1. Multiple standard outer facade connectors 7 for fixing and connecting the outer facade module are fixedly installed on the outside of the steel columns 6. The outer facade module is located outside the outer facade support module and includes a first standard outer facade 8, a second standard outer facade 9, a third standard outer facade 10, an irregularly shaped outer facade 11, and a light-transmitting outer facade 12. The core tube module, as the central support of the prefabricated tower crown structure, plays a crucial role in load-bearing and stability. Internally, it includes components such as a steel top cover, inner core shell, outer core shell, concrete core, and diaphragms. These components work together to ensure the stability of the tower crown structure under various loads. The various components of the core tube module are prefabricated and welded together in the factory, and then hoisted onto the construction site as a whole. This factory prefabrication and on-site assembly method greatly improves construction efficiency and shortens the construction period. After the concrete core is poured, the core tube module becomes the platform for subsequent construction. This facilitates the installation of the subsequent facade support modules and facade modules. The facade support modules mainly consist of steel columns and module connectors, which together provide solid support for the facade modules. The steel columns, as the main load-bearing components, are connected to the core tube modules and facade modules through the module connectors, ensuring the stability of the entire structure. The steel columns and module connectors of the facade support modules are prefabricated and welded together in the factory, and then hoisted to the construction site one by one. This design allows for high flexibility in the facade support modules, enabling adjustments and optimization based on actual needs. Through rational structural design and material selection, the facade support modules enhance the wind and earthquake resistance of the prefabricated tower crown structure. In extreme weather conditions such as strong winds or earthquakes, the facade support modules effectively absorb and disperse loads, protecting the entire structure. The facade modules are a crucial component of the prefabricated tower crown structure, and their design and installation directly impact the overall aesthetic appearance. By selecting appropriate materials, colors, and textures, a unique and beautiful architectural appearance can be created. Beyond aesthetics, the facade modules also possess functional properties. For example, translucent modules can be made of transparent polycarbonate, maintaining indoor brightness and ventilation while resisting the erosion of wind and rain. The facade modules are 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 requiring large-scale modifications to the entire structure.

[0038] like Figure 1-2 As shown, the core tube module includes a steel top cover 1 located at the top of the tower, with a central opening for convenient construction and maintenance. Circumferential and radial stiffening plates are provided at the bottom to increase the load-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 tower. A core tube outer shell 3, fixedly connected to the steel top cover 1 and the tower, is located outside the core tube inner shell 2. Both the inner and outer shells have openings in the same direction for convenient construction and maintenance. A concrete core 4 is located between the inner and outer shells. These three components together form a steel shell-concrete core composite structure. Multiple transverse diaphragms 5 are fixedly installed on the outer side of the outer shell 3. The steel top cover 1, inner shell 2, outer shell 3, and transverse diaphragms 5 are prefabricated and welded together in the factory. During construction, the entire assembly is hoisted to the top of the tower, and then the concrete core 4 is poured to form the framework of the tower crown and a platform for subsequent construction, providing a safe working surface for the work. The core tube module is mainly constructed of steel. The high strength and rigidity of steel enable the entire module to withstand significant loads and deformations, ensuring the stability of the tower crown structure. As the skeleton of the tower crown, the core tube module provides structural stability to the top of the tower and enhances the overall wind and earthquake resistance of the tower. The concrete core 4 is located between the inner shell 2 and the outer shell 3 of the core tube, serving as a filling material. This not only increases the weight of the module but also improves its compressive strength and overall stability. Multiple transverse diaphragms 5 are fixedly installed on the outside of the outer shell 3 of the core tube, providing horizontal support and 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 exterior facade support module includes multiple steel columns 6 located between the tower and the steel roof 1. The top of each steel column 6 is bolted to the steel roof 1, and the bottom is anchored, ensuring a stable connection with the tower crown structure. This not only improves the overall stability of the structure but also effectively distributes the load and enhances wind resistance. Multiple standard exterior facade connectors 7 are fixedly installed on the outside of each steel column 6. These connectors are used to securely connect the exterior facade module. The connection method of bolting the top of the steel column 6 to the steel roof 1 and anchoring the bottom is... Both robust and easy to disassemble, it improves the safety and flexibility of construction. Since the modular connectors and steel columns are welded together in the factory, they can be quickly hoisted, improving construction efficiency and reducing on-site work time, as well as reducing construction difficulty and cost. The prefabricated facade support modules reduce on-site welding work, lower 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 passages or platforms for subsequent maintenance and repair. This versatility makes the tower crown structure more flexible and practical.

[0040] like Figure 1-2As shown, the facade module includes a first standard facade 8 located at the top of the tower. A light-transmitting facade 12 is located at the top of the first standard facade 8. A second standard facade 9 is located at the top of the light-transmitting facade 12. A third standard facade 10 is located at the top of the second standard facade 9. A non-standard facade 11 is located between the third standard facade 10 and the steel roof 1. Multiple horizontal and vertical stiffening plates are provided on the inner sides of the first standard facade 8, the second standard facade 9, and the third standard facade 10. Steel plates are fixedly connected to the stiffening plates, and the steel plates have multiple bolt holes. All three standard facades 10 are fixedly connected to the standard facade connectors 7 by bolts. A light-transmitting facade connector 13 is provided between the first standard facade 8 and the light-transmitting facade 12, and between the light-transmitting facade 12 and the second standard facade 9. The light-transmitting facade connector 13 has a groove along its length on its outer side for fixing the light-transmitting facade, and multiple bolt holes on its inner side. It is fixedly connected to the top of the first standard facade 8 and the bottom of the second standard facade 9 by bolts. The light-transmitting facade 12 is secured by 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 is made of transparent material. Made of transparent polycarbonate, it allows ample natural light to enter the building interior, providing sufficient illumination for the indoor space. The irregular facade 11 is L-shaped, with multiple horizontal and vertical stiffening plates on the inner side and multiple bolt holes at the bottom, which are used to fix it to the third standard facade 10. The combination of the first standard facade 8, the second standard facade 9, the third standard facade 10, the translucent facade 12, and the irregular facade 11 forms a multi-layered facade structure, enhancing the overall stability and wind pressure resistance. The first standard facade 8, the second standard facade 9, the third standard facade 10, and the irregular facade 11 are all fixedly connected by bolts. The bolts are fixedly connected to the corresponding connectors. This connection method not only facilitates installation and disassembly, but also ensures a tight connection and stability between the various components. The outer side of the light-transmitting facade connector 13 is provided with a groove for fixing the light-transmitting facade 12, and the inner side is provided with multiple bolt holes. It is fixedly connected to the first standard facade 8 and the second standard facade 9 by bolts, ensuring the stability and firmness of the light-transmitting facade 12. The light-transmitting facade 12 is made of materials including but not limited to transparent polycarbonate, PMMA board, and glass. It has high light transmittance, which allows natural light to fully enter the interior of the tower crown, and also allows various landscape lighting devices to be cleverly arranged inside the tower crown.
