Description

Technical Field

[0001] This invention belongs to the field of tower crown technology, and more specifically, relates to an umbrella-shaped steel structure tower crown suitable for bridge tower columns and its installation method. Background Technology

[0002] Bridge towers are vertical structural components of bridges. Due to their visual impact, tower structures are important landscape elements of bridge structures, often determining the overall aesthetic tone of the bridge. The tower crown, located at the top of the tower, is of paramount importance in terms of its landscape design. In recent years, the decoration of curtain walls and lighting in the architectural field has become quite sophisticated. As a vital infrastructure in the region, the harmony between bridges and their surroundings, while remaining true to their essential nature, will become a trend in future bridge development. Simultaneously, with the improvement of people's living standards, their desire to appreciate their surroundings has gradually increased, leading to a growing demand for sightseeing. Bridge structures are generally built in areas with open views, and the tower structures soaring into the clouds, with the tower crown positioned as an excellent vantage point, make this research highly valuable in developing a tower crown structure that is structurally safe, economical, durable, and aesthetically pleasing.

[0003] Currently, the materials used in tower structures are generally pure concrete or pure steel, and the tower crown is generally made of the same type of material as the tower structure. Its functional requirements are limited to load-bearing requirements, and it often remains silent in the darkness, devoid of any modern social atmosphere.

[0004] Therefore, there is an urgent need at present for a functional component for bridge tower crowns that can overcome the shortcomings of existing technologies in terms of functional embodiment, effectively solve the problem of the single function of bridge tower crowns, and at the same time have the advantages of good integrity, simple construction, high safety and strong functionality. Summary of the Invention

The enclosure mechanism is made of high-strength, transparent, and lightweight material. The circumferential support beam group includes a top ring beam that connects multiple radially arranged radial beams into one unit, making the tower crown support steel structure at the top of the tower column an ​​umbrella-shaped steel structure.

[0007] Furthermore, the circumferential support beam assembly includes a top ring beam and a column connecting ring beam; the top ring beam connects multiple sets of spoke beams into one unit, and includes a reinforcing ring beam and a secondary ring beam. The reinforcing ring beam has one or more sets arranged in a ring shape, connecting the rear ends of multiple spoke beams into one unit; the secondary ring beam has a smaller diameter than the reinforcing ring beam, and has multiple sets arranged in a ring shape, connecting the front ends of multiple sets of spoke beams into one unit; the column connecting ring beam is arranged in a ring shape, connecting multiple sets of support columns into one unit.

They are horizontally arranged, and the bottom of the spokes is fixedly connected to the bottom of the support column by welding or bolting. Multiple spokes are arranged radially, with their spokes pointing towards the central axis of the tower column.

[0010] Furthermore, the front end of the spoke beam is longer than the rear end of the support column, providing sufficient effective space at the bottom of the tower crown umbrella-shaped steel structure, which facilitates the construction of the enclosure structure and the installation of related lighting decorations.

[0011] Furthermore, the inclined support assembly includes a first support rod and a second support rod; one end of the first support rod is fixedly connected to the front side of the support column, and the other end is fixedly connected to the bottom of the front end of the spoke beam; one end of the second support rod is fixedly connected to the rear side of the support column, and the other end is fixedly connected to the bottom of the rear end of the spoke beam.

[0012] Furthermore, the enclosure mechanism includes side enclosure and top enclosure; the side enclosure is located at the top of the tower column and at the front end of the spoke beam, its bottom is fixed by the enclosure anchoring assembly, and its top is connected and fixed by the enclosure connector provided at the front end of the spoke beam; the top enclosure is connected and fixed by the enclosure connector provided at the top of the spoke beam.

[0013] Furthermore, the bottom of the supporting column is anchored to the top of the tower column by a column anchoring assembly, which includes a first anchor rod, a first bottom anchor plate, and a first top anchor plate. The first bottom anchor plate is pre-embedded in the tower column at a corresponding depth, and its top is fixedly provided with multiple first anchor rods by welding. The first anchor rods pass through the tower column and are fixedly connected to the first top anchor plate. The top middle of the first top anchor plate is fixedly connected to the supporting column by welding.

[0014] Furthermore, the bottom of the side enclosure is fixed by an enclosure anchoring assembly, which includes a second anchor rod, a second bottom anchor plate, and a second top anchor plate. The second bottom anchor plate is pre-embedded in the tower column at a corresponding depth, and multiple second anchor rods are fixedly installed on its top by welding. The second anchor rods pass through the tower column and are fixedly connected to the second top anchor plate. The top of the second top anchor plate is provided with an enclosure connector for connecting and fixing the bottom of the side enclosure.

[0015] According to another aspect of the present invention, an installation method for an umbrella-shaped steel structure tower crown suitable for bridge tower columns is also provided, comprising the following steps:

[0016] S100: When pouring the top of the tower column, the column anchoring components and the retaining anchoring components are pre-embedded in the corresponding locations;

[0017] S200: Anchor multiple sets of support columns using column anchoring components;

[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 umbrella-shaped steel structure tower crown of the present invention, by providing a circumferential support beam group, connects multiple sets of radial beams and support columns into one body, thereby enhancing the overall stability of the tower crown structure. Through its circumferential design, when the enclosure structure is subjected to external forces (such as various wind forces at the top of the tower column), the load can be evenly transferred to the umbrella-shaped steel structure of the tower crown, which can effectively offset the impact load and enhance the applicability of the tower crown in the harsh environment at the top of the tower column. At the same time, through the circumferential design of the circumferential support beam group, there is sufficient effective space at the bottom of the umbrella-shaped steel structure of the tower crown, which facilitates the construction of the enclosure structure and the installation of related lighting decorations.

[0027] 2. The umbrella-shaped steel structure tower crown of the present invention expands the functionality of the tower crown by combining an umbrella-shaped integral steel structure with a light-transmitting enclosure structure. It mainly expands the functionality of lighting and sightseeing, greatly improves the landscape effect and practical function of the bridge tower, and meets the needs of current development. The shape of the tower crown can be adjusted according to needs, making it highly adaptable.

[0028] 3. The umbrella-shaped steel structure tower crown of the present invention can be fabricated as a whole and then hoisted, or assembled from parts on site according to construction needs, which improves the convenience and adaptability of construction. At the same time, the combination of high-performance new materials can make the tower crown structure lighter and more novel, which meets the needs of modern aesthetics.

[0029] 4. The umbrella-shaped steel structure tower crown of the present invention draws on the decorative technology of curtain walls and lighting in the field of architecture and applies it to the tower crown of bridges, which can enhance the unity between urban bridges and buildings and has a strong contemporary character.

Detailed Implementation

[0037] 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 merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figure 1-5 As shown, this invention provides an umbrella-shaped steel structure tower crown suitable for bridge towers, comprising multiple sets of supporting columns 2 circumferentially anchored to the ventilation openings at the top of the tower column 1, radial beams 5 vertically fixed to the top of the supporting columns 2, oblique support components 8 for strengthening the connection between the radial beams 5 and the supporting columns 2, a circumferential support beam group 3 connecting the multiple sets of supporting columns 2 and radial beams 5 into one unit, and an enclosure mechanism 4 located around the radial beams 5 to enclose the tower column 1; wherein, the circumferential support beam group 3 includes a top ring beam 31, which connects multiple radially arranged radial beams 5 into one unit, making the tower crown supporting steel structure at the top of the tower column 1 an umbrella-shaped steel structure. Combined with the light-transmitting enclosure mechanism 4, while ensuring the overall structural stability of the tower crown, it expands its lighting and sightseeing functions, greatly improving the landscape effect and practical function of the bridge tower, and meeting the needs of current development. The umbrella-shaped steel structure tower crown of the present invention expands the functionality of the tower crown by combining an umbrella-shaped integral steel structure with a light-transmitting enclosure structure. It mainly expands the lighting and sightseeing functions, greatly improves the landscape effect and practical function of the bridge tower, and meets the needs of current development. The shape of the tower crown can be adjusted according to the needs, making it highly adaptable.

[0039] like Figure 1-2As shown in the embodiment of the invention, the supporting column 2 is used to support the corresponding structure of the tower crown and prevent the tower crown from being damaged by external forces. It is supported by high-strength square steel and is circumferentially located at the ventilation opening at the top of the tower column 1. Further, the bottom of the supporting column 2 is anchored to the top of the tower column 1 by a column anchoring assembly 6. The column anchoring assembly 6 includes a first anchor rod 61, a first bottom anchor plate 62, and a first top anchor plate 63. The first bottom anchor plate 62 is pre-embedded in the tower column 1 at a corresponding depth, and its top is fixedly provided with multiple first anchor rods 61 by welding. The first anchor rods 61 pass through the tower column 1 and are fixedly connected to the first top anchor plate 63. The top middle of the first top anchor plate 63 is fixedly connected to the supporting column 2 by welding. Preferably, the top of the first anchor rod 61 is provided with a threaded part, which passes through the first top anchor plate 63 and is threadedly connected to a nut, pressing the first top anchor plate 63 to the top of the tower column 1, thereby improving the installation and disassembly efficiency of the supporting column 2 and facilitating construction by workers.

[0040] The spoke beams 5 are used to support the top of the enclosure mechanism 4. They are horizontally arranged, and their bottoms are fixedly connected to the bottom of the supporting column 2 by welding or bolting. Furthermore, multiple spoke beams 5 are arranged radially, with their shafts pointing towards the central axis of the tower column 1. Furthermore, the length of the spoke beams 5 at the front end of the supporting column 2 is greater than that at the rear end, providing sufficient effective space at the bottom of the tower crown umbrella-shaped steel structure, facilitating the later construction of the enclosure mechanism 4 and the installation of related lighting decorations.

[0041] To enhance the load-bearing capacity of the spoke beam 5, an inclined support assembly 8 is provided between the spoke beam 5 and the supporting column 2, thereby supporting the front and rear ends of the spoke beam 5 and greatly improving its load-bearing capacity. The inclined support assembly 8 includes a first support rod 81 and a second support rod 82; one end of the first support rod 81 is fixedly connected to the front side of the supporting column 2, and the other end is fixedly connected to the bottom of the front end of the spoke beam 5, thus forming a triangular structure. This disperses the pressure on the top of the spoke beam 5 onto the first support rod 81 and the supporting column 2, enhancing the stability of the overall structure. One end of the second support rod 82 is fixedly connected to the rear side of the supporting column 2, and the other end is fixedly connected to the bottom of the rear end of the spoke beam 5, thus forming a triangular structure. This disperses the pressure on the top of the spoke beam 5 onto the first support rod 81 and the supporting column 2, enhancing the stability of the overall structure.

[0042] To connect multiple sets of spoke beams 5 and supporting columns 2 into one unit and enhance the overall stability of the tower crown structure, a circumferential support beam group 3 is provided to fix and connect the multiple sets of spoke beams 5 and supporting columns 2 respectively. The circumferential support beam assembly 3 includes a top ring beam 31 and a column connecting ring beam 32. The top ring beam 31 connects multiple sets of spoke beams 5 into one unit. It includes a reinforcing ring beam 311 and a secondary ring beam 312. The reinforcing ring beam 311 has two or more sets arranged in a ring shape, connecting the rear ends of multiple spoke beams 5 into one unit. The diameter of the secondary ring beam 312 is smaller than that of the reinforcing ring beam 311, which greatly reduces the load on the front end of the spoke beam 5. It is arranged in a ring shape in multiple sets, connecting the front ends of multiple spoke beams 5 into one unit. Furthermore, the weight of the rear end of the spoke beam 5 with the reinforcing ring beam 311 installed is the same as the weight of the front end of the spoke beam 5 with the secondary ring beam 312 installed, so that the center of gravity of the spoke beam 5 with the top ring beam 31 fixedly installed is located at the top of the support column 2, ensuring the top support balance of the support column 2 and avoiding the overturning of the spoke beam 5 due to uneven force. The column connecting ring beam 32 is arranged in a ring shape and is at the same height as the first support rod 81 and the second support rod 82, connecting multiple sets of support columns 2 into one, thereby distributing the load on the top of the radial beam 5 to multiple sets of support columns 2 for synchronous bearing, ensuring the overall stability of the crown structure.

[0043] In this embodiment of the invention, by providing a circumferential support beam group 3, multiple sets of radial beams 5 and support columns 2 are connected as a whole, thereby enhancing the overall stability of the tower crown structure. Through its circumferential design, when the enclosure mechanism 4 is subjected to external forces (such as various wind forces at the top of the tower column 1), the load can be evenly transferred to the umbrella-shaped steel structure of the tower crown, which can effectively offset the impact load and enhance the applicability of the tower crown in the harsh environment at the top of the tower column 1. At the same time, through the circumferential design of the circumferential support beam group 3, there is enough effective space at the bottom of the umbrella-shaped steel structure of the tower crown, which facilitates the construction of the enclosure mechanism 4 and the installation of related lighting decorations.

[0044] In this embodiment of the invention, the enclosure mechanism 4 is used to enclose the tower crown umbrella-shaped steel structure. It is made of high-strength transparent lightweight material (such as acrylic transparent sheet, PC transparent sheet, PET transparent sheet, etc.) and includes side enclosure 41 and top enclosure 42.

[0045] The side enclosure 41 is located at the top of the tower column 1 and at the front end of the spoke beam 5, and its bottom is fixed by the enclosure anchoring assembly 7. The enclosure anchoring assembly 7 includes a second anchor rod 71, a second bottom anchor plate 72, and a second top anchor plate 73; the second bottom anchor plate 72 is pre-embedded in the tower column 1 at a corresponding depth, and its top is fixed with multiple second anchor rods 71 ​​by welding; the second anchor rods 71 ​​protrude from the tower column 1 and are fixedly connected to the second top anchor plate 73; the top of the second top anchor plate 73 is provided with an enclosure connector for connecting and fixing the bottom of the side enclosure 41. Furthermore, the front end of the spoke beam 5 is provided with an enclosure connector, thereby connecting and fixing the top of the side enclosure 41.

[0046] The top enclosure 42 is connected and fixed by the enclosure connector provided on the top of the spoke beam 5, and its outer periphery is sealed to the top of the side enclosure 41 with sealant to prevent rainwater and dust from entering.

[0047] The umbrella-shaped steel structure tower crown of the present invention expands the functionality of the tower crown by combining an umbrella-shaped integral steel structure with a light-transmitting enclosure structure. It mainly expands the lighting and sightseeing functions, greatly improves the landscape effect and practical function of the bridge tower, and meets the needs of current development. The shape of the tower crown can be adjusted according to the needs, making it highly adaptable.

[0048] The umbrella-shaped steel structure tower crown of the present invention can be fabricated as a whole and then hoisted, or assembled from parts on site according to construction needs, which improves the convenience and adaptability of construction. At the same time, the combination of high-performance new materials can make the tower crown structure lighter and more novel, which meets the needs of modern aesthetics.

[0049] The umbrella-shaped steel structure tower crown of this invention applies the decorative techniques of curtain walls and lighting in the architectural field to the tower crown of bridges, which can enhance the unity between urban bridges and buildings and has a strong contemporary character.

[0050] This invention also provides a method for installing an umbrella-shaped steel structure tower crown suitable for bridge tower columns, comprising the following steps:

[0051] S100: When pouring the top of the tower column 1, the column anchoring component 6 and the retaining anchoring component 7 are pre-embedded in the corresponding positions;
