Description

Technical Field

[0001] This invention belongs to the field of building curtain walls, and specifically relates to a rhomboid composite curtain wall structure and its construction method. Background Technology

[0002] As important public buildings, stadiums are increasingly emphasizing artistic expression and visual impact in their facade design. Currently, many stadium curtain walls still primarily feature flat or simple curved surfaces, resulting in a monotonous visual effect and failing to showcase the building's individuality and dynamism. To achieve complex three-dimensional shapes, existing technologies largely rely on highly customized, complex heavy steel structure support systems paired with irregularly shaped panels, leading to bulky structures, extremely high requirements for processing and installation precision, long construction cycles, and high costs.

[0003] In particular, for large curtain walls that require different depths and levels of three-dimensional effects on the same building facade, such as a deep pyramid at the top and an inner and outer double-sided shell at the bottom, how to ensure the structural stability and reliable connection of each section, and achieve efficient modular prefabrication and on-site installation, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] This invention provides a rhomboid composite curtain wall structure and its construction method to address the technical challenges in large curtain walls with a deep pyramidal top and inner and outer double-sided shells at the bottom. These challenges include ensuring the structural stability and reliable connection of each section, as well as achieving efficient modular prefabrication and on-site installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rhomboid composite curtain wall structure, comprising an upper pyramidal curtain wall area and a lower inner and outer double-prism curtain wall area. The upper pyramidal curtain wall area is composed of multiple rhomboid three-dimensional units arranged repeatedly along the circumference of the top of the stadium. Each rhomboid three-dimensional unit includes four inner steel pipes forming the rhombus and four apex protruding steel pipes. One end of the four apex protruding steel pipes converges and is fixed, and the other end is respectively fixed to the corner of the four inner steel pipes. The convergence point of the four apex protruding steel pipes extends beyond the plane of the four inner steel pipes. The inner steel pipes of adjacent rhomboid three-dimensional units are arranged parallel to each other. The lower inner and outer double-prism curtain wall area is composed of multiple inner and outer double-prism three-dimensional units arranged repeatedly along the circumference of the top of the stadium. The structure consists of an inner and outer double-prism three-dimensional unit, comprising four inner steel pipes, four outer steel pipes, and four connecting steel pipes. The four inner steel pipes form a prism shape, and the four outer steel pipes also form a prism shape that protrudes beyond the prism shape formed by the inner steel pipes. The two ends of the connecting steel pipes are respectively connected to the intersection corners of the inner and outer steel pipes. The inner steel pipes of adjacent inner and outer double-prism three-dimensional units are arranged in parallel. The inner steel pipes of adjacent upper pyramidal curtain wall areas and lower inner and outer double-prism curtain wall areas are arranged in parallel. Four triangular aluminum single panels are installed on the prism three-dimensional unit to form a three-dimensional prism shape, and four trapezoidal aluminum single panels are installed on the inner and outer double-prism three-dimensional units to form a three-dimensional shape with prisms on both the outer and inner sides.

[0006] By adopting the above technical solutions, this structure possesses the following advantages: 1. Rich three-dimensional visual effects: By combining the "pyramidal" three-dimensional units with the "inner and outer double-sided shell" three-dimensional units in upper and lower sections, a spatial shape of a four-sided pyramidal space is formed at the top and a four-sided frustum space at the bottom. This breaks the monotony of traditional curtain walls, creating a deep, multi-layered, and dynamically changing light and shadow effect, greatly enhancing the artistic expression and iconic status of the stadium's facade. 2. Reasonable structure and clear force distribution: Both types of units adopt the spatial truss principle to construct the main framework, with a clear force path. Through a unified force transmission system composed of inner steel pipes, connecting steel plates, and square tube connectors, the curtain wall load is effectively transferred to the main structure, ensuring high safety. 3. Standardized and modular design: Each three-dimensional unit can be prefabricated in a factory, decomposing the complex spatial shape into standard steel pipes, adapters, and panel modules, improving processing accuracy, quality consistency, and production efficiency. 4. Convenient construction and high fault tolerance: The unitized framework can be hoisted as a whole, significantly reducing the amount and time spent on high-altitude operations. The Z-shaped EPDM first adapter is flexible, absorbing installation errors and structural deformation. The L-shaped and T-shaped second and third adapters provide three-dimensional adjustment, reducing the stringent requirements for absolute precision on-site and making installation simple and quick. 5. Durability and Maintainability: The main metal components are coated with fluorocarbon, and the EPDM adapters effectively prevent steel-aluminum contact corrosion, improving overall durability. The modular design also facilitates future replacement and maintenance of individual panels. This design solves the technical challenges of ensuring structural stability and reliable connections in each section of a large curtain wall with a deep pyramidal top and inner and outer double-sided shells at the bottom, while achieving efficient modular prefabrication and on-site installation.

[0007] Preferably, the installation method of the inner steel pipes of the rhomboid solid unit and the inner and outer double rhomboid solid unit is the same. A connecting steel plate is fixed to the inner side of the inner steel pipe, and a square tube connector is set between the two connecting steel plates. The two connecting steel plates and the square tube connector are connected by bolts. The square tube connector is fixedly connected to the main steel structure. The main steel structure is the skeleton of the stadium. It is usually matched to the position of the curtain wall according to the shape of the curtain wall. This is a conventional construction method and will not be described in detail here. A Z-shaped transition is set on the outer side of the inner steel pipe. Part 1: The two sides of the Z-shaped adapter are attached to the inner steel pipe and fixed with screws. The middle of the Z-shaped adapter is spaced from the inner steel pipe and connected with an L-shaped adapter 2 by screws. Screws pass through and fix the inner steel pipe, adapter 1 and adapter 2 in sequence. The other side of adapter 2 is fixed with an aluminum profile keel by screws. A triangular aluminum single panel 1 is fixedly installed on the outside of the aluminum profile keel of the rhomboid three-dimensional unit. A trapezoidal aluminum single panel 2 is fixedly installed on the outside of the aluminum profile keel of the inner and outer double rhomboid three-dimensional unit.

[0008] By adopting the above technical solution, the inner steel pipe is connected to the main steel structure, and the outer aluminum profile keel and aluminum single panel are installed. The structure is reasonable, the stress is clear, the overall structural strength is high, and the stability is strong.

[0009] Preferably, the installation method of the top protruding steel pipe of the rhomboid solid unit and the connecting steel pipe of the inner and outer double rhomboid solid unit is the same. The outer side of the connecting steel pipe is also provided with a Z-shaped adapter. The two sides of the Z-shaped adapter are attached to the connecting steel pipe and fixed with screws. The middle of the Z-shaped adapter is spaced from the connecting steel pipe and connected with an L-shaped adapter two by screws. The screws fix the connecting steel pipe, adapter one and adapter two. The two adapter two are connected to the connecting steel pipe and are staggered. The other side of the adapter two is fixed with an aluminum profile keel by screws. The two waists of the trapezoidal aluminum single plate two are fixed to the aluminum profile keel connected to the connecting steel pipe. The two adapter two form an angle facing outward. The four triangular aluminum single plates one on the top protruding steel pipe of the rhomboid solid unit form a three-dimensional rhomboid. The four trapezoidal aluminum single plates two on the connecting steel pipe of the inner and outer double rhomboid solid unit form a three-dimensional shape with rhomboids on both the outer and inner sides.

[0010] By adopting the above technical solution, aluminum profile keel is also set on the outside of the top protruding steel pipe and the connecting steel pipe, resulting in high overall structural strength and strong stability.

[0011] Preferably, a T-shaped adapter three is provided on the outer side of the outer steel pipe. The horizontal plate of the adapter three is arc-shaped and attached to the outer steel pipe and fixed to the outer steel pipe by screws. The vertical plate of the adapter three is fixed to the aluminum profile keel by screws. The top edge of the trapezoidal aluminum single panel two is fixed to the aluminum profile keel connected to the outer steel pipe. The four trapezoidal aluminum single panels two form a three-dimensional shape with both the outer and inner sides being prismatic.

[0012] By adopting the above technical solution, aluminum profile keel is also set on the outside of the outer steel pipe, and the four sides of the trapezoid are fixedly installed, resulting in high overall structural strength and strong stability.

[0013] Preferably, the square tube connector is provided at three points on the inner steel tube, at both ends and in the middle, with a distance of 200mm between the ends and the apex.

[0014] By adopting the above technical solution, the structural connection is stable and the overall stability is strong.

[0015] Preferably, the included angle between adjacent aluminum single panel one and aluminum single panel two is 124°-165°. By adopting the above technical solution, the angle is reasonable and the visual effect is good.

[0016] Preferably, 5mm thick aluminum alloy angle brackets are fixed to the four sides of aluminum single panel one and aluminum single panel two, and the aluminum alloy angle brackets are fixed to the aluminum profile keel by screws.

[0017] By adopting the above technical solution, a gap is provided that facilitates installation and fixation.

[0018] Preferably, the first adapter is a 1mm thick EPDM profile, the second adapter is an aluminum alloy profile, and the third adapter is an aluminum alloy profile.

[0019] By adopting the above technical solutions, EPDM profiles effectively isolate the direct contact between steel pipes (steel) and aluminum alloy profiles, preventing corrosion caused by direct contact between the two different metals in a humid environment. They absorb minor displacements and vibrations caused by temperature changes, wind loads, or slight structural deformations, avoiding noise or stress concentration caused by hard collisions between metals. The excellent elasticity of EPDM allows it to perfectly fill all uneven gaps between the steel pipe and the aluminum alloy under the pressure of bolt pre-tightening force and the aluminum alloy profile, forming a continuous and reliable waterproof and airtight sealing barrier.

[0020] A construction method for a rhomboid composite curtain wall structure includes the following steps: S1. Measurement and layout and main structure verification: According to the design drawings, measure and lay out the installation control lines and elevation lines of each curtain wall unit on the main steel structure of the gymnasium, and verify the position of the embedded parts or connection points of the main steel structure. S2: Prefabrication of unit skeleton in factory: In the factory, steel pipe skeletons of rhomboid solid units and inner and outer double rhomboid solid units are processed and manufactured in batches, and the positioning and preliminary connection of connecting steel plates, adapters and aluminum profile keels on the corresponding steel pipes are completed to form unit skeleton modules; S3: Installation of connecting components: Fix the square tube connectors to the main steel structure according to the layout position; S4: Zoned hoisting and fixing: S4.1: Hoisting the inner and outer double-prism curtain wall units: Hoist the prefabricated inner and outer double-prism three-dimensional unit skeleton modules to the installation position, and fasten the connecting steel plates on the inner steel pipes to the two sides of the already installed square tube connectors with bolts to complete the fixing of the unit to the main structure; install all units in this area in sequence along the circumference in this way; S4.2: Hoisting the upper pyramidal curtain wall unit: After the lower area is installed, the prefabricated first pyramidal three-dimensional unit skeleton module is hoisted to the top installation position and fixed to the main steel structure through its connecting steel plate and square tube connector, and ensures that it is aligned and parallel with the inner steel tube of the adjacent inner and outer double pyramidal three-dimensional unit below. S5: Panel installation: After all unit frames are installed and aligned, the factory-prefabricated aluminum single panel one and aluminum single panel two are fixed to the aluminum profile keel of the corresponding unit using aluminum alloy angle brackets and screws to complete the enclosure; S6: Sealing and finishing treatment: Apply weather-resistant sealant to the joints of adjacent aluminum single panel one and aluminum single panel two, and perform edge finishing and finishing treatment on the top and bottom of the curtain wall and the junction with other building parts.

[0021] The beneficial effects of this invention are reflected in the following aspects: 1. Rich three-dimensional visual effects: By combining the "pyramidal" three-dimensional unit with the "inner and outer double-sided shell" three-dimensional unit in upper and lower sections, a spatial shape of a four-sided pyramidal space is formed in the upper part and a four-sided frustum space in the lower part. This breaks the monotony of traditional curtain walls and creates a deep, multi-layered, and dynamically changing light and shadow effect, greatly enhancing the artistic expression and iconic nature of the stadium's facade. 2. Reasonable structure and clear force distribution: Both types of units adopt the spatial truss principle to construct the main skeleton, with a clear force path. Through a unified force transmission system composed of inner steel pipes, connecting steel plates, and square tube connectors, the curtain wall load is effectively transferred to the main structure, ensuring high safety. 3. Standardized and modular design: Each three-dimensional unit can be prefabricated in a factory, decomposing the complex spatial shape into standard steel pipes, adapters, and panel modules, improving processing accuracy, quality consistency, and production efficiency. 4. Convenient construction and high fault tolerance: The unitized skeleton can be hoisted as a whole, significantly reducing the amount and time spent on high-altitude operations. The Z-shaped EPDM first adapter is flexible, absorbing installation errors and structural deformation. The L-shaped and T-shaped second and third adapters provide three-dimensional adjustment, reducing the stringent requirements for absolute precision on-site and making installation simple and quick. 5. Durability and Maintainability: The main metal components are coated with fluorocarbon, and the EPDM adapters effectively prevent steel-aluminum contact corrosion, improving overall durability. The modular design also facilitates future replacement and maintenance of individual panels. This design solves the technical challenges of ensuring structural stability and reliable connections in each section of a large curtain wall with a deep pyramidal top and inner and outer double-sided shells at the bottom, while achieving efficient modular prefabrication and on-site installation.

The structure is reasonable, the stress distribution is clear, and the overall structural strength and stability are high.

[0029] The installation method of the apex-protruding steel pipe 4 of the rhomboid solid unit and the connecting steel pipe 6 of the inner and outer double rhomboid solid units is the same. A U-shaped adapter 13 is also provided on the outer side of the connecting steel pipe 6. The two sides of the U-shaped adapter 13 are attached to the connecting steel pipe 6 and fixed by screws 14. The middle of the U-shaped adapter 13 is spaced from the connecting steel pipe 6 and connected to an L-shaped adapter 2 15 by screws 14. The screws 14 fix the connecting steel pipe 6, adapter 13, and adapter 2 15. The two adapters 2 15 are connected to the connecting steel pipe 6 and are staggered. On the other side, an aluminum profile keel 16 is fixed by screws 14. The two waists of the trapezoidal aluminum single panel 8 are fixed to the aluminum profile keel 16 connected by the connecting steel pipe 6. The two adapters 15 form an angle facing outward. The four triangular aluminum single panels 7 on the top protruding steel pipe 4 of the rhomboid three-dimensional unit form a three-dimensional rhombus. The four trapezoidal aluminum single panels 8 on the connecting steel pipe 6 of the inner and outer double rhomboid three-dimensional unit form a three-dimensional shape with rhomboids on both the outer and inner sides. The top protruding steel pipe 4 and the outer side of the connecting steel pipe 6 are also equipped with aluminum profile keels 16. The overall structure has high strength and strong stability.

[0030] A T-shaped adapter 17 is provided on the outer side of the outer steel pipe 5.
