Description

Technical Field

[0001] This invention relates to architectural curtain wall technology. The diamond-cut grille unit frame assembly is a welded unit assembly that positions the diamond-cut grille units into and out of the aluminum profile frame at different heights, so as to achieve a consistent architectural visual effect for the overall appearance of the diamond-cut decorative grille in the space. It belongs to the field of architectural curtain wall technology. Background Technology

[0002] In current architectural design, most projects use traditional aluminum profile connection methods such as corner bracket connection, nail connection, and bolt connection for aluminum profile frame connection. The combination of aluminum profile frame splicing for spatial positioning of diamond-cut grille unit involves aluminum alloy profiles entering and exiting different spaces with uneven joints, which cannot well display the appearance effect and limits the guarantee of the finished frame appearance size. Traditional connection methods can no longer meet the needs of current projects.

[0003] Building Information Modeling (BIM) is a tool used in architecture, engineering, and civil engineering. It primarily involves 3D graphics, object-oriented design, and computer-aided design related to architecture, and is widely used in architectural design and construction.

[0004] Invention patent CN201310155938.6 describes a stone-like lightweight aluminum alloy grating. It consists of an aluminum alloy lightweight grating coated with a stone-like paint. The grating is constructed by welding horizontal aluminum alloy profile segments, vertical aluminum alloy profile segments, and irregularly shaped aluminum alloy profile segments together. The irregularly shaped aluminum alloy profile segments include those with planar shapes such as straight lines, curves, squares, circles, ellipses, or other polygons. Based on the spatial coordinates and shapes of various lightweight aluminum alloy gratings provided in the design drawings and the actual dimensions of the construction site, the aluminum alloy profile segments are welded together in a component factory to form the aluminum alloy grating. A layer of stone-like paint is then sprayed onto it to produce various stone-like lightweight aluminum alloy gratings. This stone-like lightweight aluminum alloy grating has a stone-like appearance, is lightweight, meets structural load-bearing requirements and safety performance, and its manufacturing method is simple.

[0005] Invention patent CN202111344493.7 discloses a cantilevered irregular aluminum grid curtain wall and its construction method. The cantilevered irregular aluminum grid curtain wall includes vertical cantilever components (3), horizontal beams (4), accessory plates (8), and connectors (9). One end of the vertical cantilever component is cantilevered and installed on the concrete structure (1) of the building. Several vertical cantilever components are spaced apart horizontally and longitudinally in the installation area of ​​the irregular aluminum grid curtain wall. The horizontal beam is connected to the other end of the vertical cantilever component through the accessory plate. Several horizontal beams are horizontally connected to adjacent vertical cantilever components at the same horizontal height to form a support frame. The irregular aluminum grid (5) is longitudinally installed on the horizontal beam through the connector, so that the irregular aluminum grid is cantilevered and installed on the outside of the building, and spliced ​​to form an aluminum grid curtain wall. The irregular aluminum grid is quickly installed through the support frame, and the irregular aluminum grid is quickly spliced ​​to form an irregular aluminum grid curtain wall through the connector.

[0006] Invention patent CN202311165374.4 discloses a primary installation method for a wall panel fixing device for diamond-cut facet designs. The device includes a square steel frame, a U-shaped guide rail, an adjusting component, and an installation tube. The adjusting component includes a connecting tube, with a first connecting block and a second connecting block fixedly connected to both ends. A slider and a connecting plate are respectively provided on opposite sides of the first and second connecting blocks. A rotating shaft is mounted on the outer side of the connecting plate via a fixing plate. This invention adjusts the overall length of the adjusting component by adjusting the length of the connecting tube, thereby adjusting the tilt angle of the honeycomb aluminum panel and the stone panel. Simultaneously, the sliding cooperation between the adjusting component and the U-shaped guide rail enables rapid installation of the honeycomb aluminum panel and the stone panel without manual fixing. This simple operation saves time and effort, is less likely to damage the stone panel, and facilitates the tight joining of adjacent honeycomb aluminum panels for optimal splicing results. Summary of the Invention

[0007] The technical problem solved by this invention is to provide a spatial diamond-cut grille unit frame assembly component that breaks away from conventional aluminum alloy profile connection methods, so as to ensure the spatial positioning and connection safety and good docking effect of the aluminum profile frame of the diamond-cut grille unit.

[0008] Another object of the present invention is to provide a welding method for the aforementioned spatial diamond-cut grid unit frame assembly component.

[0009] This invention provides a spatial diamond-cut grille unit frame assembly, designed according to the spatial diamond-cut effect of architecture. The unit frame assembly consists of at least eight profile frame single keels welded together to form the unit frame of the spatial diamond-cut grille. The base frame is formed by aluminum profile one, aluminum profile two, and aluminum profile four and aluminum profile five with the same cross-section on both sides. Four aluminum profile three with the same cross-section form a four-legged bracket with protruding intersections. The four legs of the four-legged bracket are connected to the four inner corners of the base frame, thus forming the spatial diamond-cut grille unit frame assembly.

[0010] The spatial diamond-cut grille unit frame assembly provided by this invention meets the spatial stress requirements of the curtain wall exterior decoration system, and ensures the rationality and safety reliability of the curtain wall structure while achieving the desired diamond-cut surface effect.

[0011] Based on the above scheme, a three-dimensional model of the diamond-cut facet shape is given according to the BIM model, and the bevel joints of the single keel profiles of the spatial irregular positioning and docking aluminum profile frame are tightly fitted.

[0012] Furthermore, aluminum profile one and aluminum profile two on the opposite side form the relatively long side of the bottom frame, while aluminum profile four and aluminum profile five with the same side cross-section on the two long sides form the short side of the bottom frame.

[0013] Preferably, the framework of the spatial diamond-cut grid curtain wall system is formed by the connection of two bottom frames.

[0014] The present invention also provides a welding method for the aforementioned spatial diamond-cut grid unit frame assembly component, wherein the aluminum alloy frame of the spatial diamond-cut surface is precisely cut and machined at an angle so that the bevel assembly of each keel meets the design requirements of the spatial diamond-cut grid; after the diamond-cut keel is fixed by clamps for spatial positioning and docking, the overall welded and formed component is polished and then coated with fluorocarbon.

[0015] Specifically, a three-dimensional model of the diamond-cut facet shape is provided through BIM model. The joints between the single keel profiles of the spatial irregular positioning and docking aluminum alloy profile frame are processed. The docking shape of each profile is precisely cut at the angle. The irregularly cut keel is fixed with clamps for spatial positioning and docking. After adjusting the positioning dimensions, the aluminum profile is subjected to strong penetration welding.

[0016] The welding requirements are as follows: 1) The surface of the welding wire must be clean and free of oxide scale. Welding wire with a thick oxide scale on its surface is not allowed to be used. 2) The assembly of the weldment should be accurate. Before the formal welding, the bevel size of the aluminum profile should be checked and welding can only be carried out after it is qualified. 3) Before welding begins, the oxide layer on the surface of the aluminum profile at the welding location must be cleaned using a stainless steel brush. 4) The weld and heat-affected zone surfaces shall be 100% inspected and shall be free from defects such as cracks, lack of fusion, porosity, arc craters, slag inclusions and spatter. 5) Before welding, fixtures and backing plates should be made for the aluminum profiles; ensure that the parts are clamped on both sides when using fixtures; the backing plate material should be stainless steel or carbon steel; 6) The arc crater should be filled and the arc connection should be fused and penetrated; when closing the arc, raise the arc at a uniform speed and at the same time accelerate the filling of the welding wire until the arc is extinguished, so that the weld at the arc extinguishing point protrudes locally and grind off the excess height.

[0017] The technical solution adopted by this invention to solve its technical problem is: a spatial diamond-cut grille unit frame assembly component, which uses clamps to fix the diamond-cut keel for spatial positioning and docking, and after welding and polishing, it is coated with fluorocarbon. This not only meets the overall external dimensions of the frame assembly, but also meets the smooth docking effect of the exterior decoration after the frame docking, meets the rigidity and strength requirements, and also achieves the integrity and continuity of the exterior decoration effect of the frame. The spatial diamond-cut aluminum alloy frame welding method is a good solution for the unit assembly component system.

[0018] The beneficial effects of this invention are: while pursuing a perfect visual effect, it first respects and values ​​the spatial diamond-cut facet effect design of the building. Through the welding and polishing of the aluminum alloy frame of the combined component system, the aesthetics and functionality of the aluminum profile frame system curtain wall of the spatial diamond-cut facet grille unit are better improved, thereby reflecting the architect's design intention and the quality of the building itself.

[0022] A spatial diamond-cut grille unit-type frame assembly component, such as Figures 1 to 3 As shown, designed according to the spatial diamond-cut facet effect of the building, the unit frame of the spatial diamond-cut facet grille is formed by welding eight profile frames together. The four sides are formed by aluminum profile 1, aluminum profile 2, and aluminum profiles 4 and 5 with the same side cross-section. Four aluminum profiles 3 with the same cross-section form the four-legged support with protruding intersections. The four legs of the support are connected to the four corners of the inner side of the four sides, forming the unit frame of the spatial diamond-cut facet grille.

[0023] Based on the BIM model, a three-dimensional model of the diamond-cut facet shape is provided, and the bevel joints of the single keel profiles of the spatial irregular positioning and docking aluminum profile frame are tightly fitted.

[0024] like Figure 1 and 2 As shown, aluminum profile 1 and aluminum profile 2 on the opposite side form the long side of the four-sided frame, while aluminum profiles 4 and 5 with the same side cutouts form the short side of the four-sided frame.

[0025] The welding method for the spatial diamond-cut grille unit frame assembly component in this embodiment is as follows: The aluminum alloy frame with the diamond-cut facets is precisely cut at an angle so that the bevels of each keel meet the design requirements of the diamond-cut facet grid. After the diamond-cut facet keels are fixed with clamps for spatial positioning and docking, the overall welded keel is polished and then coated with fluorocarbon.

[0026] The fixture includes a clamp and a backing plate.

[0027] A 3D model of the diamond-cut facet shape is generated using BIM modeling. The joints between the individual keel profiles of the spatial irregular positioning and docking aluminum alloy frame require special processing. The docking shape of each profile is precisely cut at an angle. Special clamps that match the aluminum profiles are used to fix the irregularly cut keels for spatial positioning and docking. After adjusting the positioning dimensions, the aluminum profiles are welded with equal penetration. The specific welding requirements are as follows: 1. The surface of the welding wire must be clean and free of oxide scale. Welding wire with a thick oxide scale on its surface is not allowed to be used. 2. The assembly of weldments should be accurate. If the assembly is not good, it should not be forced to fit together to avoid excessive stress. Before the formal welding, the bevel size should be checked and welding can only be carried out after it is qualified. 3. Before welding begins, the oxide layer on the surface of the aluminum material to be welded must be cleaned using a special stainless steel brush. 4. The weld and heat-affected zone surfaces shall be 100% inspected and shall be free from defects such as cracks, lack of fusion, porosity, arc craters, slag inclusions and spatter. 5. Aluminum is prone to deformation and collapse during welding. Therefore, clamps should be made in a targeted manner before welding. When using clamps, both sides of the parts need to be clamped. The rigidity and clamping force of the clamps should be moderate. If they are too small, they will not be able to control the deformation. If they are too large, the weld will be too restrained and will easily crack. The backing plate material is generally stainless steel or carbon steel. 6. The arc crater should be filled, and the arc connection should be fused and penetrated. When closing the arc, raise the arc at a uniform speed and accelerate the filling of the welding wire until the arc is extinguished, so that the weld at the extinguished arc protrudes locally, and grind off any excess height.

[0028] A curtain wall composed of the spatial diamond-cut grille unit frame assembly components of the present invention, such as... Figure 4 As shown, the two spatial diamond-cut grilles 10 and 20 are assembled together, that is, the bottom frames of the two spatial diamond-cut grille unit frame-frame combination components are joined together, and the aluminum profile 3 forms a four-legged bracket with protruding intersections and is connected to the bottom frame, covering part of the diamond-cut grille curtain wall formed by the grille on the unit frame.

[0029] This embodiment utilizes an aluminum profile frame assembly for a spatial diamond-cut grille unit. This assembly addresses the connection between different spatial levels, overcoming the limitations of existing aluminum profile frame components where the joints are not smooth, hindering aesthetic presentation and limiting the final frame's dimensions. Traditional connection methods are insufficient for the project's needs. The integrated welding of the aluminum profile diamond-cut frame is a reasonable and reliable method for connecting spatial frames, allowing for the welding and fixing of irregular spatial shapes to adapt to architectural requirements. This breaks away from conventional aluminum alloy profile connection methods.
