Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a steel arch-supported aluminum alloy mesh shell cable-stayed hybrid structure system. Background Technology

[0002] Greenhouse buildings have specific requirements for the environment in which plants grow, necessitating a more transparent building facade and a certain number and area of ​​operable windows. Therefore, the curtain wall of the building's exterior and the main structure need to be designed as an integrated whole.

[0003] Compared to conventional structures, the stiffness of multi-material hybrid spatial structures in steel and aluminum alloy hybrid structural systems requires a rational arrangement of the logical relationships between components to meet the overall stability, wind resistance, and earthquake resistance requirements. The aluminum alloy single-layer grid shell also serves as the curtain wall keel, forming an integrated structure and curtain wall. In the design and construction of such span, irregularly shaped buildings, to achieve unique architectural functions and forms, complex hybrid structural systems composed of different materials (such as steel, aluminum alloy, and cables) are often required. However, the integration of such multi-material, variable-stiffness structures faces severe challenges. First, there is a lack of mature and reliable overall structural solutions that enable steel arches with significantly different stiffnesses and flexible aluminum alloy grid shells to work collaboratively. Their stability is mutually restrictive rather than complementary; traditional rigid connections easily lead to stress concentration, while simple hinges cannot achieve effective internal force transfer and support. Second, to meet the aesthetic requirements of slender and lightweight architecture, how to provide effective outward stability for a single steel arch becomes a key problem; traditional methods relying on rigid supports are neither economical nor effective. Summary of the Invention

[0004] The purpose of this invention is to provide a steel arch-supported aluminum alloy mesh shell cable-stayed hybrid structural system, which aims to solve a series of key technical problems faced by traditional structural systems in terms of material coordination, stress stability and construction feasibility when realizing the functions of large-span and irregular-shaped buildings.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel arch-supported aluminum alloy mesh shell cable-stayed hybrid structure system, comprising prestressed cables evenly distributed along the outer surface of the precast aluminum alloy mesh shell and conforming to its outer curved surface contour; Multiple hangers are welded between the precast aluminum alloy mesh shell and the prestressed cable, arranged in an array along the curve of the prestressed cable. A steel arch is fixedly installed at the end of each hanger, and the steel arch is fixedly installed on the prestressed cable. The cross-section of the steel arch is an irregularly shaped hyperbolic torsion rhomboid square tube.

[0006] Preferably, the prefabricated aluminum alloy mesh shell includes a connector and aluminum alloy rods, wherein: The connector includes at least four inclined insertion interfaces, the aluminum alloy rod is inserted into the insertion interfaces, and is fixed by M10 bolts passing through the connector and the aluminum alloy rod; Both the insertion interface and the sidewall of the aluminum alloy rod are welded with web shear rings, and after installation, the two web shear rings are fixed by multiple M10 bolts.

[0007] Preferably, the wall thickness of the connector is not less than 2 / 3 of the flange of the aluminum alloy rod.

[0008] Preferably, the prefabricated aluminum alloy mesh shell further includes H-shaped steel welded to the side wall of the rectangular steel pipe; The aluminum alloy rod is attached to the end of the H-shaped steel and also includes a web node plate, which covers the joint between the aluminum alloy rod and the H-shaped steel and is fixed by multiple M10 bolts; It also includes a concrete wall and a lower support. The bottom of the lower support is welded with centrally distributed cross-shaped shear keys. The cross-shaped shear keys are inserted into a pre-drilled adapter groove in the concrete wall and fixed by expansion bolts. A pillow block is inserted into the port of the lower support, and an upper support is inserted into the top of the pillow block. An elastic metal ring plate is placed between the upper support and the pillow block. In the default state, the elastic metal ring plate maintains a predetermined distance between the adjacent surfaces of the upper support and the pillow block. The part of the elastic metal ring plate that contacts the upper support is horizontal, while the part that contacts the pillow block is arc-shaped. The rectangular steel pipe is welded to the upper support.

[0009] Preferably, the number of web node plates is four, and they are fixed at least on two opposite sides; Preferably, the pillow block is any one of a steel component, a wooden component, or a high-toughness rubber block, and when the pillow block is a steel component or a wooden component, a rubber gasket is provided between the contact surface of the pillow block and the lower support.

[0010] Preferably, the prestressed cable passes through perforations centrally distributed on two adjacent sides of the steel arch; The sidewall of the steel arch is welded with a cable fixing block, and also includes a hinge, which is assembled with the cable fixing block by bolts to clamp the prestressed cable; The steel arch has diaphragms welded to two opposite vertices, parallel to the prestressed cables. A fusion cavity is formed between the partition and the two adjacent sides of the steel arch, and the fusion cavity is filled with a stack of nylon strips surrounding the outer wall of the prestressed cable.

[0011] Preferably, the component also includes an I-shaped connector, wherein wing plates are fixedly provided on both opposite sides of the two ends of the I-shaped connector, and one end of the aluminum alloy rod is inserted between the two wing plates at one end of the I-shaped connector and fixed by bolts; It also includes an inner ear plate with a baffle welded to its end. The inner ear plate protrudes through the perforation on the I-shaped connector and is rotatably connected to the insert plate fixedly installed at the end of the boom.

[0012] Preferably, one of the inner ear plates is rotatably provided with at least two of the insert plates.

[0013] Preferably, the stress ratio of the steel arch is not more than 0.8 Pa, but not less than 0.4 Pa.

[0014] In the above technical solution, the steel arch-supported aluminum alloy mesh shell cable-stayed hybrid structure system provided by the present invention has the following beneficial effects: 1. Fully utilize the performance advantages of different materials to form a collaborative working mechanism. The steel arch, as the core skeleton of the overall structure, provides the main load-bearing capacity for the system; the lower precast aluminum alloy mesh shell has the characteristics of good durability, light weight, high degree of industrialization, and integrated with the curtain wall, which can flexibly adapt to the functional and morphological requirements of complex curved buildings. Moreover, the steel arch is connected to the precast aluminum alloy mesh shell through hangers, providing it with effective out-of-plane stiffness support. At the same time, the steel arches are connected by prestressed cables to form an overall force-bearing system, significantly enhancing the lateral stability of the steel arch.

[0015] 2. Secondly, considering the unsuitability of aluminum alloy materials for welding, and the fact that joint connections can significantly impact structural safety and durability, high-strength bolts are used at the four-bar intersection points—specifically, the connection between the connector and the aluminum alloy member. This facilitates on-site installation, and the slightly curved web shear ring design ensures a tight fit between the connector and the aluminum alloy member, effectively meeting the fabrication and installation requirements of complex, irregularly shaped thin-shell structures.

[0016] 3. The precast aluminum alloy mesh shell is connected to the upper support via hanger nodes, and sleeper blocks are installed at the supports to connect with the lower support. This design effectively releases temperature stress and reduces the adverse effects of temperature on the structure.

[0017] 4. The out-of-plane stability of the steel arch is ensured by the prestressed cables, while the suspended precast aluminum alloy mesh shell, steel arch, and prestressed cables are located on different spatial curved surfaces, forming parallel stress layers. The hangers are connected to the steel arch and precast aluminum alloy mesh shell using pins, giving the nodes a certain degree of rotational capability. The prestressed cables connect multiple steel arches into a whole, playing a crucial role in improving the overall structural integrity. That is, the magnitude of the prestress in the prestressed cables has a relatively small impact on the natural vibration period of the structure, while the cross-sectional area of ​​the prestressed cables has a more significant impact.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, a steel arch-supported aluminum alloy mesh shell cable-stayed hybrid structure system includes prestressed cables 2 that are evenly distributed along the outer surface of the precast aluminum alloy mesh shell 3 and match its outer curved surface contour. Multiple hangers 4 are welded between the precast aluminum alloy mesh shell 3 and the prestressed cable 2, and are arranged in an array along the curve of the prestressed cable 2. The hangers 4 and the prestressed cable 2 are fixed by a steel arch 1. The cross-section of steel arch 1 is a rhomboid square tube.

[0023] Specifically, the stress ratio of the aforementioned steel arch 1 does not exceed 0.8 Pa, but is not lower than 0.4 Pa. The above technology fully utilizes the performance advantages of different materials to form a collaborative working mechanism. The steel arch 1, as the core skeleton of the overall structure, provides the main load-bearing capacity for the system; the lower prefabricated aluminum alloy mesh shell 3 possesses characteristics such as good durability, light weight, high degree of industrialization, and integrated design with the curtain wall, enabling it to flexibly adapt to the functional and morphological requirements of complex curved building surfaces.

[0024] It should be noted that the morphology creation and optimization of the prefabricated aluminum alloy reticulated shell 3 in this example is performed using the force density method. A self-developed Matlab program was used to locate the highest ridge line according to architectural requirements, adjust the side curvature of the reticulated shell, and introduce only self-weight load for initial loading. A suitable force density value (force density flow q = s / l, where l is the element length and s is the element internal force) was found based on engineering experience. A system of linear equations for equilibrium was established based on the support conditions (lower support 36, upper support 38, and pillow block 37), and the equilibrium state was iteratively sought by gradually adjusting the axial forces of the members (aluminum alloy member 32 and hanger 4). While ensuring the force density flow remains constant, the node coordinates (connector 31, H-beam 341, steel arch 1) and the calculated lengths of the members (aluminum alloy member 32 and hanger 4) were updated, and the load was reloaded. After several iterations, convergence was determined. After convergence, the single-layer reticulated shell structure exhibits predominantly axial forces under its own weight, with minimal contribution from end moments to the stabilizing stress, thus achieving a relatively rational shell shape and grid division. To meet architectural requirements and maximize in-plane and out-of-plane stiffness, the initial reticulated shell is not an ideal arch axis. Based on the Kelvin reticulated shell, quadrilateral grids are adjusted in areas with lower stress to increase light transmission. This method allows for the identification of a rational integrated curtain wall skin structure according to the building's form requirements.

[0025] It should be noted that, due to the non-weldability of aluminum alloy, the supports (lower support 36 and upper support 38) are bolted together to form a steel component, which can then be flexibly welded to the supports.

[0026] Furthermore, the steel arch 1 is connected to the precast aluminum alloy mesh shell 3 via the hanger 4, providing it with effective out-of-plane stiffness support. At the same time, each steel arch 1 is connected to the others via prestressed cables 2, forming an integrated force-bearing system, which significantly enhances the lateral stability of the steel arch 1.

[0027] As a further embodiment of the present invention, combined with Figure 2 and Figure 3 As shown, the prefabricated aluminum alloy mesh shell 3 includes a connector 31 and aluminum alloy rods 32, wherein: The connector 31 includes at least four inclined insertion interfaces, and the aluminum alloy rod 32 is inserted into the insertion interfaces and fixed by M10 bolts passing through the connector 31 and the aluminum alloy rod 32. Both the insertion interface and the sidewall of the aluminum alloy rod 32 are welded with web shear rings 33, and after installation, the two web shear rings 33 are fixed by multiple M10 bolts.

[0028] Specifically, the aforementioned plate-type node is used for the four H-shaped aluminum components whose insertion interfaces intersect at a single point, with the components being non-orthogonal and having a slight angle. To enhance the shear resistance of the node, all web shear rings 33 are connected to form a web shear ring 33. The web shear ring 33 is bolted to the web of the component, so that the four components intersecting at the node share the shear force through the shear ring, achieving an equal-strength connection. The lower and upper cover plates of the node extend beyond bs1 (the larger of 200mm and web length / 2 + 50mm), and the extended plates expand beyond the shear ring by 0.5bf (bf is the flange width of the component) and are chamfered with R=75mm. The shear ring is installed after the components in each direction are assembled, and its wall thickness is taken as the larger value of the web thickness of each connecting component. To prevent the bolt spacing in the middle part from being too large, the web shear ring 3 is designed with a set of two bolt holes (bolt diameter 9.66mm, hole diameter 10mm) at the center of each through aluminum alloy member 32. The lower support 36, upper support 38, and bolster block 37 of the node are connected by welds. This node is versatile; aluminum alloy components can be replaced with steel components at the lower support 36 and upper support 38. After replacement, the connection with the node plate can be made by full welding or bolt welding. In this case, the cover plate protrusion bs1 is the larger of 300mm and web length / 2+45mm, and the protrusion plate expands by 0.7bf.

[0029] Furthermore, in combination Figure 4 As shown, the prefabricated aluminum alloy mesh shell 3 in the above embodiment also includes an H-shaped steel 341 welded to the side wall of the rectangular steel pipe 34; The aluminum alloy rod 32 is attached to the end of the H-beam 341, and also includes a web node plate 35, which covers the joint between the aluminum alloy rod 32 and the H-beam 341 and is fixed by multiple M10 bolts.

[0030] Specifically, the support nodes of the precast aluminum alloy mesh shell 3 are welded to meet construction alignment requirements, but the strength of the aluminum alloy components degrades after welding. Therefore, the aluminum components in the support sections are replaced with steel structures for connection, allowing for welding at the supports. When converting the aluminum alloy components to steel components, all connections are made with bolts. The web connecting plates and flange connecting plates are both Q355B steel plates with the same thickness as the aluminum alloy components. The aluminum alloy components at the contact points are coated with an anodized film of approximately 10µm thickness, and a galvanized layer is added at the contact points with the connecting steel plates to isolate the aluminum. The isolation layer must be tightly bonded to the steel and aluminum surfaces, and the surfaces must be derusted before coating. This structure effectively solves the corrosion and wear problems caused by the contact between steel and aluminum. A rectangular steel pipe 34 is added perpendicular to the component direction and welded to the conversion steel component to increase its out-of-plane stiffness.

[0031] It also includes a concrete wall 100 and a lower support 36. The bottom of the lower support 36 is welded with centrally distributed cross shear keys 361. The cross shear keys 361 are inserted into the pre-opened adapter groove in the concrete wall 100 and fixed by expansion bolts. A pillow block 37 is inserted into the port of the lower support 36, and an upper support 38 is inserted into the top of the pillow block 37. An elastic metal ring plate 39 is placed between the upper support 38 and the pillow block 37. In the default state, the elastic metal ring plate 39 keeps a predetermined distance between the adjacent surfaces of the upper support 38 and the pillow block 37. The part of the elastic metal ring plate 39 that contacts the upper support 38 is horizontal, while the part that contacts the pillow block 37 is arc-shaped. The rectangular steel pipe 34 is welded to the upper support 38.

[0032] It should be noted that there are four web node plates 35, which are fixed at least on two opposite sides; Secondly, the pillow block 37 is any one of steel, wood or high-toughness rubber, and when the pillow block 37 is steel or wood, a rubber gasket is provided between the contact surface with the lower support 36.

[0033] Specifically, a cross-shaped shear key 361 is welded to the center of the bottom of the lower support 36. This shear key is inserted into a pre-set fitting groove in the concrete wall 100 during construction and finally fixed with expansion bolts. This design primarily resists the shear force generated by horizontal forces (such as wind loads and seismic actions) borne by the structure, preventing horizontal slippage between the support and the foundation.

[0034] Secondly, the cross-shaped shear key 361 is inserted into the pre-set fitting groove in the concrete wall 100 during construction and finally fixed with expansion bolts. This design mainly resists the shear force generated by the horizontal forces (such as wind loads and seismic action) borne by the structure, preventing horizontal slippage between the support and the foundation.

[0035] The bolster block 37 can be made of steel, wood, or high-toughness rubber, providing different stiffness and damping options. When a rigid material (steel or wood) is selected, a rubber gasket is placed between its contact surface and the lower support 36 to provide cushioning and adjustment.

[0036] As another embodiment further provided by the present invention, combined with Figure 5 As shown, the prestressed cable 2 passes through the perforations centered on two adjacent sides of the steel arch 1; The side wall of the steel arch 1 is welded with a cable fixing block 11, and also includes a hinge. The hinge is assembled with the cable fixing block 11 by bolts to clamp the prestressed cable 2. Inside the steel arch 1, at two opposite vertices, there are diaphragms 12 parallel to the prestressed cables 2; A fusion cavity is formed between the two adjacent sides of the partition 12 and the steel arch 1, and the fusion cavity is filled with a stack of nylon strips 13 surrounding the outer wall of the prestressed cable 2.

[0037] Specifically, the prestressed cable 2, as a nonlinear unit, can generate out-of-plane stiffness through in-plane tension. Due to the constraint of the cables between the steel arches 1, the hybrid structural system works together, which is beneficial to the structure. However, increased cable force will generate a downward resultant force, leading to increased vertical displacement of the steel arch 1, which is detrimental to the aluminum alloy mesh shell with high displacement limit requirements. Therefore, the prestress magnitude can be controlled to prevent cable relaxation under various working conditions. Considering the difficulty of constructing a single cable through the steel arch 1, the prestressed cables between the steel arches are tensioned in segments and connected by press-fit anchors. Holes are opened in the two side plates through which the rhomboid steel arch passes, with a hole diameter approximately 10mm wider than the diameter of the prestressed cable 2 for easy installation. The internal partition plates 12 are symmetrically arranged with respect to the steel cables, offset by 20mm on each side. After the cable body is installed, cable fixing blocks are welded on-site at the holes. The tensile strength of the weld must meet the cable tension to ensure the cable body and steel arch deform together. The surface of the cable body must be cleaned of oil, dust, and loose rust before being coated with an epoxy zinc-rich primer protective layer. The tensioning sequence must strictly follow the graded loading method. After each level of tensioning, the load is maintained for 2-4 minutes to check the tension and elongation deformation values. The next level of loading is only carried out after the structural deformation has stabilized and there are no abnormalities in the cable.

[0038] As another embodiment further provided by the present invention, combined with Figure 6 As shown, it also includes an I-shaped connector 5. Wing plates 51 are fixedly provided on both opposite sides of the two ends of the I-shaped connector 5. One end of the aluminum alloy rod 32 is inserted between the two wing plates 51 at one end of the I-shaped connector 5 and fixed by bolts. It also includes an inner ear plate 6, with a baffle 61 welded to its end. The inner ear plate 6 protrudes through the hole in the I-shaped connector 5 and is rotatably connected to the insert plate 41 fixedly installed at the end of the rod 4.

[0039] An inner ear plate 6 is rotatably equipped with at least two insert plates 41.

[0040] Specifically, the steel arch 1 provides out-of-plane support for the precast aluminum alloy grid shell 3 via hangers 4. The hangers 4 and the precast aluminum alloy grid shell 3 are connected by d=60mm pins. The inner ear plate 6 is connected to the I-shaped connector 5 of the node via double-sided fillet welds. The extended portion of the inner ear plate 6 is welded to the insert plate 41 using a first-stage full penetration weld. To facilitate axial force transmission, insert plates 41 are added to the hangers 4 and connected to the extended portion of the inner ear plate 6. The hangers 4 are connected by pins. The full-span scaffolding supporting the entire grid shell can only be removed after adjusting the displacement and reaction force of each suspension point. The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
