Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and more specifically, to an aluminum profile with a protective mechanism. Background Technology

[0002] In the field of modern architecture and outdoor facilities, aluminum profiles have become the mainstream material for pavilion construction due to their excellent corrosion resistance, lightweight properties, and recyclability. Especially in landscape architecture, aluminum profiles are widely used in the load-bearing frame systems of various pavilions because of their good processing performance and aesthetic design.

[0003] However, when these aluminum profiles are deployed in areas with high typhoon activity, their insufficient environmental adaptability leads to performance degradation. Specifically, continuous wind-induced vibration loads induce progressive damage accumulation within the material, resulting in irreversible plastic deformation in stress concentration areas. This mechanical performance degradation exhibits a significant spatiotemporal cumulative effect, and the actual service life is far lower than the design expectation. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum profile with a protective mechanism to solve the problem that aluminum profiles are prone to fatigue damage accumulation due to wind vibration in high-frequency typhoon areas, which leads to a sharp reduction in service life.

[0005] To achieve the above objectives, an aluminum profile with a protective mechanism is provided, comprising:

[0006] The outer support frame is a symmetrical closed polygonal frame. Its two top frame sides expand outward and meet to form a apex structure, while its two bottom frame sides converge inward and meet to form a bottom corner structure.

[0007] The inner reference frame is a closed polygon with the same number of sides as the outer support frame. The two are set concentrically and all corresponding sides are parallel to each other.

[0008] A honeycomb matrix, filling the space between the outer support frame and the inner reference frame, is composed of multiple regular hexagonal elements arranged symmetrically in a mirror image along the geometric central axis;

[0009] The bottom frame side of the outer support frame is shorter than the top frame side, and the top and bottom corners are at the same angle.

[0010] In the above technical solution, the symmetrical polygons of the outer support frame and the consistent angles of the top and bottom corners can ensure that wind-induced vibration and other loads are transmitted evenly. The shorter bottom side length than the top side can reduce the weight and optimize the moment of inertia. The inner reference frame is concentric with the outer support frame and the corresponding sides are parallel, which provides positioning for the honeycomb matrix and constrains its radial deformation. The mirrored arrangement of the regular hexagonal units of the honeycomb matrix can disperse stress in multiple directions and absorb energy through deformation, ultimately improving the stability and wind resistance of the overall structure.

[0011] Based on this, a side frame edge is fixedly connected between the top frame edge and the bottom frame edge;

[0012] The two top frame edges extend to both sides beyond the side frame edges to form corner eaves.

[0013] In this technical solution, the side frame edges connect to the top and bottom frame edges, forming a complete closed outer support frame structure. This enhances the overall rigidity and stability of the frame, allowing the load to be distributed more evenly among the frame edges. The eaves formed by the extension of the top frame edge extend beyond the side frame edges, guiding rainwater to drain quickly and preventing it from seeping into the profile interior and dovetail grooves. At the same time, it can shield the side structure to a certain extent, reducing the direct erosion of the side connection areas by the external environment.

[0014] In another technical solution, the surfaces of the outer support frame, the honeycomb matrix, and the inner reference frame are all anodized.

[0015] This technical solution involves anodizing the surfaces of the outer support frame, honeycomb matrix, and inner reference frame to form a dense oxide film. This oxide film isolates the aluminum profile substrate from air, moisture, and other corrosive media, effectively slowing down the electrochemical corrosion process. Especially in harsh environments such as high salt spray and humidity, it can improve the corrosion resistance of the aluminum profile and ensure its long-term stable service.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. In this aluminum profile with a protective mechanism, the outer support frame is a symmetrical closed polygon. The top frame edge expands outward to form a apex, and the bottom frame edge converges inward to form a bottom angle with the same angle. The bottom edge is shorter than the top edge, so that the wind vibration load can be evenly transferred to the honeycomb matrix filled between it and the inner reference frame. The inner reference frame and the outer support frame are concentric and their corresponding edges are parallel, providing an installation positioning surface for the honeycomb matrix and constraining the radial deformation amplitude of the honeycomb matrix. The honeycomb matrix is ​​composed of multiple regular hexagonal units arranged in a mirror symmetrical manner. After receiving the load transferred by the outer support frame, it disperses the stress by virtue of its isotropic characteristics and absorbs energy through the compression deformation of the side walls, thereby slowing down the gradual accumulation of damage inside the material, avoiding irreversible plastic deformation in the stress concentration area, and extending the service life of the aluminum profile in the high-frequency area of ​​typhoons.

[0018] 2. In this aluminum profile with a protective mechanism, the corner eaves formed by the extension of the top frame can guide rainwater to drain quickly away along the outside of the profile. Combined with the tapering design at the bottom of the outer support frame, it can prevent liquid from accumulating and seeping into the interior of the profile and the dovetail groove, reducing the corrosion of the material by water. At the same time, the multi-cavity structure of the honeycomb matrix extends the water penetration path, blocks the capillary water seepage channels, and improves the weather resistance of the profile.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 As shown, the aluminum profile in this embodiment is specifically designed for the load-bearing structure of the pavilion roof, and is particularly suitable for horizontally arranged main beams and purlin systems. It provides an aluminum profile with a protective mechanism, including an outer support frame 1, a honeycomb matrix 2, and an inner reference frame 3. In the overall layout, the outer support frame 1 wraps around the honeycomb matrix 2, and the honeycomb matrix 2 tightly surrounds the inner reference frame 3, forming a stable, nested configuration.

[0025] The outer support frame 1 adopts a symmetrical closed polygonal frame configuration. Its two top frame sides 15 extend outward at a specific expansion angle to intersect and form the apex 11 structure, while its two bottom frame sides 16 converge inward at the same angle to intersect and form the bottom corner 12 structure. This symmetrical inclined configuration forms a continuous force transmission path: when wind load acts on the apex 11 region, the force flow is dispersed and transmitted to both sides along the inclined surface of the top frame side 15, and then transmitted through the side frame side 17 to the converging inclined surface of the bottom frame side 16, finally converging at the bottom corner 12. The bottom frame side 16 is designed to be shorter than the top frame side 15, forming a tapered trapezoidal cross-section structure. This allows the load intensity to exhibit a gradient attenuation during the transmission process. The concentrated load borne by the apex 11 region, after being transmitted through the top frame side 15, forms a dispersed low-intensity load distribution on the reduced-section bottom frame side 16, avoiding the stress abrupt change phenomenon at the corner of a traditional right-angle frame.

[0026] The honeycomb matrix 2 filling the space between the inner and outer frames is composed of multiple regular hexagonal units 21 arranged symmetrically along the geometric central axis, forming a honeycomb network. Each regular hexagonal unit 21 is connected to each other by six equal-length sidewalls at a 120° angle, forming a perfectly centrally symmetrical geometric unit. Adjacent regular hexagonal units 21 share boundary walls to form a continuous mesh structure, and all unit wall thicknesses remain uniform. When external loads are transmitted to this structure, the six sidewalls of each regular hexagonal unit 21 simultaneously bear the force, automatically decomposing the linear load into components in six directions. This multi-directional force transmission path allows the load to be rapidly dispersed in the mesh structure. The shared boundary walls between the regular hexagonal units 21 form continuous transmission channels, ensuring that the component forces are uniformly diffused along the matrix plane. When subjected to force, the unit walls undergo orderly structural deformation, and the sidewalls produce recoverable micro-buckling within the elastic range. The unit as a whole exhibits a rhomboid distortion trend, consuming external input energy. The periodic structure formed by the mirror-symmetric arrangement causes adjacent regular hexagonal elements 21 to deform in opposite directions, generating mutually canceling stress fields and effectively neutralizing peak stress. Furthermore, stress concentration at the wall connection nodes is alleviated through uniform wall thickness design.

[0027] The inner reference frame 3 adopts a closed polygonal configuration, and its geometry and dimensions correspond to those of the outer support frame 1. The inner reference frame 3 and the outer support frame 1 are concentrically arranged, with parallel spatial relationships established between all corresponding sides, forming a positioning reference system to ensure that the installation position tolerance of each regular hexagonal unit 21 in the honeycomb matrix 2 is controlled within a minimum range. The rigid boundary of the inner reference frame 3 directly contacts the inner edge of the honeycomb matrix 2, forming a physical constraint interface. When the honeycomb matrix 2 is subjected to external loads, the inner reference frame 3 limits the radial displacement of the regular hexagonal unit 21 through continuous contact surfaces, ensuring that the deformation of the regular hexagonal unit 21 remains within the elastic safety zone, preventing excessive distortion that could lead to permanent damage or weakening of strength. At structural connection nodes, the parallel edge design of the inner reference frame 3 maintains the geometric alignment of adjacent regular hexagonal units 21. When loads are transmitted, the connection nodes between the regular hexagonal units 21 maintain a uniform stress state, eliminating the risk of local stress abrupt changes caused by positional offsets and providing stable boundary conditions for the honeycomb matrix 2.

[0028] In the symmetrical closed polygonal frame configuration of the outer support frame 1, the side frame edge 17 serves as a key transition structure connecting the top frame edge 15 and the bottom frame edge 16. Its longitudinal extension length is strictly matched with the frame tilt angle to ensure that the load forms a stress-free transmission path between the expanding apex angle 11 and the converging bottom angle 12. The dovetail groove 13 on the surface of the side frame edge 17 is arranged along the entire length of the profile. The tilt angle of the groove bottom forms a self-locking fit with the fittings, and the groove width is optimized to ensure compatibility with standard fasteners.

[0029] To address the need for heavy rainfall protection in typhoon-prone areas, the corner eaves 14, extending from the top frame edge 15 to both sides, form a water-guiding slope with the bottom surface of the extended section and the top surface of the side frame edge 17. This slope extends beyond the frame body, forming a cantilever structure. The eaves edge features a downward curve design to create a drip line, forming a continuous drainage channel with the side frame edge 17. When rainwater impacts the top corner 11 area, the water flow is rapidly diverted along the expanding slope of the corner eaves 14 and discharged to both sides through the water-guiding channel, effectively blocking the lateral penetration of liquid into the dovetail groove 13 area. During the surface treatment process, the inner surface of the regular hexagonal unit 21 of the honeycomb matrix 2 achieves uniform oxide film deposition through a dedicated electrode, forming a continuous sealing layer on the wall of the regular hexagonal unit 21. This eliminates capillary seepage paths in porous structures, while simultaneously improving the material's corrosion resistance, blocking chloride ion penetration channels, and ensuring long-term structural stability in the high-humidity, high-salt environment of the seaside.

[0030] Manufacturing Process: First, a combined flow-dividing mold is designed based on the profile cross-section. The main mold cavity corresponds to the outline of the outer support frame 1, and the inner mold core synchronously forms the honeycomb matrix 2 and the inner reference frame 3 structure. 6063-T5 aluminum alloy round ingots are selected as raw materials. After homogenization treatment at 530℃ to eliminate casting stress, they are heated to 480℃ and enter the extrusion process. The aluminum ingot is divided into multiple streams of outer metal through the mold flow-dividing bridge, filling the main body of the outer support frame 1. The central flow-dividing hole precisely forms the inner reference frame 3, and the middle area forms a thin-walled network of the honeycomb matrix 2 through 18 sets of micro-guide holes. The extrusion process uses variable speed control: initially, the outer frame is rapidly filled at 12m / min; upon entering the honeycomb area, the speed is reduced to 5m / min to ensure the complete formation of the 0.8mm thin wall; in the final stage, the speed is restored to 8m / min to complete the overall extrusion.

[0031] The formed profiles are immediately subjected to online water mist quenching, rapidly reducing the temperature from 500℃ to below 60℃ to create a fine-grained, strengthened microstructure. Subsequently, a multi-roll straightener performs three-dimensional straightening to eliminate bending deformation from the extrusion process, controlling straightness to within 0.3mm / m. The surface treatment stage employs sulfuric acid anodizing to form a 12-15μm thick oxide film on the profile surface, with the electrolyte temperature maintained at 20±2℃ and the current density at 1.2A / dm³. 2 After being treated under these conditions for 30 minutes, a surface hardness of HV350 or higher was finally obtained. Critical dimensions, such as the dovetail groove 13, were precision milled twice using CNC milling to ensure that the inclination angle deviation of the groove bottom was less than 0.05° and the surface roughness Ra ≤ 1.6μm.
