[0028] A structural profile and a production method thereof according to an embodiment of the present invention are described below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 7 The present invention aims to provide an embodiment of a structural profile, aiming to improve or even overcome the defects of glass fiber reinforced composite materials and reduce the difficulty of applying glass fiber reinforced composite materials.

[0030] In this embodiment, the structural profile includes a first profile 100, a second profile 110 and a frame 120. Among them, one of the first profile 100 and the second profile 110 is mostly located on the indoor side, and the other of the first profile 100 and the second profile 110 is mostly located on the outdoor side, and the first profile 100 and the second profile 110 can clamp a curtain wall panel, a door panel or a window glass between them.

[0031] In some specific embodiments of the present invention, the first profile 100 and the second profile 110 can be aluminum extruded profiles to form various cross-sectional shapes to meet different installation and layout requirements.

[0032] In some specific embodiments of the present invention, the first profile 100 and the second profile 110 can be made of channel steel, square tube, etc., and necessary processing can be performed to reduce manufacturing costs and at the same time have higher strength.

[0033] Reference Figures 1 to 3 In some specific embodiments of the present invention, the first profile 100 can include a first outer profile 220 and a first inner profile 230. The cross-sections of the first outer profile 220 and the first inner profile 230 are both semi-enclosed. The first outer profile 220 and the first inner profile 230 are connected at the semi-enclosed opening. The first inner profile 230 is used to accommodate and connect the skeleton 120.

[0034] In some specific embodiments of the present invention, the cross-sections of the first outer profile 220 and the first inner profile 230 can be semi-enclosed, including that the first outer profile 220 and the second outer profile are rectangular square tubes, one side of the rectangular square tube is cut open, or one side of the rectangular square tube is not closed during extrusion, thereby reserving an opening for connecting the skeleton 120.

[0035] In some specific embodiments of the present invention, the first outer profile 220 and the first inner profile 230 can be connected at a semi-enclosed opening, including the first outer profile 220 and the first inner profile 230 being connected at the semi-enclosed opening by welding to simplify installation and, at the same time, make the first profile 100 a whole, thereby improving the strength of the first profile 100.

[0036] Reference Figure 3In some specific embodiments of the present invention, the semi-enclosed opening can be located at the corner of the rectangular tube, thereby meeting the connection needs of buildings or doors and windows at the corner positions.

[0037] In some specific embodiments of the present invention, the second profile 110 may include a second inner profile and a second outer profile, the second outer profile is arranged with reference to the first outer profile 220 , and the second inner profile is arranged with reference to the first inner profile 230 .

[0038] Reference Figures 4 to 7 In some specific embodiments of the present invention, the first profile 100 can have a semi-enclosed groove 240 for connecting to the skeleton 120. The cross-section of the semi-enclosed groove 240 is L-shaped, which is convenient for connecting a glass fiber reinforced composite material profile 130 to the skeleton 120.

[0039] In some specific embodiments of the present invention, the number of the semi-enclosed grooves 240 may be two to meet the need of connecting two glass fiber reinforced composite material profiles 130 .

[0040] In some specific embodiments of the present invention, the first profile 100 can have a semi-enclosed groove 240 for accommodating the two first side flanges 150. The cross-section of the semi-enclosed groove 240 is T-shaped, which can not only meet the need of connecting the two glass fiber reinforced composite material profiles 130, but also help to reduce the distance between the two glass fiber reinforced composite material profiles 130, making it convenient for the two glass fiber reinforced composite material profiles 130 to fit closely.

[0041] In some specific embodiments of the present invention, a separation rib may be provided in the semi-enclosed groove 240 with a T-shaped cross section, so that the two glass fiber reinforced composite material profiles 130 are staggered by a certain distance to reduce the friction between the two glass fiber reinforced composite material profiles 130 .

[0042] In some specific embodiments of the present invention, the second profile 110 may be arranged with various decorative elements to meet the needs of curtain wall arrangement.

[0043] Reference Figures 3 to 7 For the first profile 100 and the second profile 110 made of aluminum alloy, the first profile 100 and the second profile 110 can also have multiple ribs and multiple openings, which are convenient for assembly into a three-dimensional structure by threading installation, which not only meets the installation requirements but also reduces the difficulty of installation.

[0044] The frame 120 is used to connect the first profile 100 and the second profile 110, so as to facilitate the indoor profile and the outdoor profile to be connected together to form a whole, which is convenient for bearing.

[0045] In this embodiment, the skeleton 120 includes at least one glass fiber reinforced composite material profile 130. The glass fiber reinforced composite material profile 130 is continuous fiber, fiber felt, fiber fabric added with thermosetting resin and then formed by pultrusion process. Thermosetting resin includes polyurethane resin, epoxy resin, unsaturated resin, and vinyl resin.

[0046] Structurally, the glass fiber reinforced composite material profile 130 includes a base plate 140 , and the base plate 140 has a first side flange 150 and a second side flange 160 . The first side flange 150 is used to connect to the first profile 100 , and the second side flange 160 is used to connect to the second profile 110 .

[0047] In some specific embodiments of the present invention, the first side flange 150 can be made to protrude toward both sides of the substrate 140, and at the same time, the second side flange 160 can protrude toward both sides of the substrate 140, so that the cross-section of the glass fiber reinforced composite material profile 130 is an I-shape, thereby preventing the glass fiber reinforced composite material profile 130 from escaping from the slots of the first profile 100 and the second profile 110.

[0048] In some specific embodiments of the present invention, the first side flange 150 may protrude toward one side of the substrate 140 , while the second side flange 160 may protrude toward the other side of the substrate 140 , so that the cross section of the glass fiber reinforced composite material profile 130 is Z-shaped.

[0049] In some specific embodiments of the present invention, the first side flange 150 and the second side flange 160 can be made to protrude toward the same side of the substrate 140, so that the cross-section of the glass fiber reinforced composite material profile 130 is semi-frame-shaped or door frame-shaped. Therefore, the first side flange 150 and the second side flange 160 can be subjected to force to prevent the first profile 100 and the second profile 110 from moving away from each other, and also prevent the first side flange 150 or the second side flange 160 from escaping from the corresponding slot.

[0050] In summary, the present invention sets a skeleton 120 so that the skeleton 120 includes at least one glass fiber reinforced composite material profile 130, and the glass fiber reinforced composite material profile 130 includes a substrate 140. Therefore, the substrate 140 can be used to bear the force of the first profile 100 and the second profile 110 moving away from each other, thereby fully utilizing the mechanical advantages of the glass fiber reinforced composite material.

[0051] The present invention provides a first side flange 150 and a second side flange 160 , which can facilitate the connection of the first profile 100 and the second profile 110 , facilitate installation by snap-on or threading, reduce the use of screws, and help avoid the generation of thermal bridges.

[0052] On the other hand, the first side flange 150 and the second side flange 160 increase the dimension perpendicular to the substrate 140, improve the transverse tensile and shear resistance, improve the defects of the material itself, and reduce the application limitations of the glass fiber reinforced composite material.

[0053] In some specific embodiments of the present invention, in the cross section of the skeleton 120 , the number of the glass fiber reinforced composite material profiles 130 can be two, and the two glass fiber reinforced composite material profiles 130 are arranged in an I-shape.

[0054] It is easy to understand that, in this embodiment, by setting the number of glass fiber reinforced composite material profiles 130 to two, the specifications of the skeleton 120 in the direction perpendicular to the connection line of the first profile 100 and the second profile 110 can be increased, and the possibility of the substrate 140 being bent under force can be reduced. At the same time, the two glass fiber reinforced composite material profiles 130 are arranged in an I-shape, which is beneficial to improving the connection strength between the skeleton 120 and the first profile 100 and the second profile 110, and reducing the risk of detachment failure.

[0055] In the cross section of the skeleton 120, the number of the glass fiber reinforced composite profiles 130 is two, which means that two glass fiber reinforced composite profiles 130 can be identified in the area shown in the figure, but it does not mean that the number of the glass fiber reinforced composite profiles 130 is only two, and it can be reasonably increased according to the length of the first profile 100 and the second profile 110 and the height of the building.

[0056] When two glass fiber reinforced composite material profiles 130 are arranged in an I-shape, the base plates 140 of the two glass fiber reinforced composite material profiles 130 may overlap in the extending direction of the profiles.

[0057] It is easy to understand that the base plates 140 of the two glass fiber reinforced composite material profiles 130 overlap in the profile extension direction, and it is necessary to pay attention to changing the orientation of the glass fiber reinforced composite material profiles 130 during assembly.

[0058] The first side protrusion 150 and the second side protrusion 160 may be oriented toward the same side of the substrate 140 , or may be oriented toward both sides of the substrate 140 .

[0059] The two glass fiber reinforced composite material profiles 130 are arranged in an I-shape, and the two glass fiber reinforced composite material profiles 130 can be arranged side by side and installed in the direction of the semi-enclosed grooves 240 on the first profile 100 and the second profile 110 to reduce the difficulty of installation.

[0060] In some specific embodiments of the present invention, the substrates 140 of two glass fiber reinforced composite material profiles 130 can be arranged in close contact or with a gap therebetween to meet different usage requirements.

[0061] The base plates 140 of the two glass fiber reinforced composite material profiles 130 are arranged close to each other or with a gap, which can be determined by the upper half surrounding groove 240 of the first profile 100, thereby reducing the difficulty of arrangement.

[0062] Reference Figure 3 In some specific embodiments of the present invention, the frame 120 may further include a semi-enclosed profile 170 covering the two first side flanges 150 , and the semi-enclosed profile 170 is inserted into the slot of the first profile 100 .

[0063] It is easy to understand that this embodiment, by providing the semi-enclosed profile 170, also facilitates the assembly of the two glass fiber reinforced composite profiles 130, so that the skeleton 120 is a separate component, that is, the skeleton 120 is manufactured and then assembled as a whole without the need to assemble them one by one.

[0064] It should be noted that whether the semi-enclosed profile 170 belongs to the first profile 100 and the second profile 110, or to the frame 120, is only a division based on the production process.

[0065] In some simplified solutions, the semi-enclosed profile 170 may also be equivalent to the first inner profile 230 and the second inner profile.

[0066] Reference Figure 3 In some specific embodiments of the present invention, the glass fiber reinforced composite material profile 130 may include a frame-shaped glass fiber inner rib 180 and a glass fiber reinforced composite material shell 190 covering the frame-shaped glass fiber inner rib 180 .

[0067] It is easy to understand that this embodiment can increase the physical volume of the glass fiber reinforced composite material profile 130 and improve its strength by providing a frame-shaped glass fiber inner rib 180 and a glass fiber reinforced composite material outer shell 190. At the same time, it can reduce the difficulty of glass fiber infiltration and dispersion, thereby improving the product quality of the glass fiber reinforced composite material profile 130.

[0068] In some specific embodiments of the present invention, the glass fiber reinforced composite material shell 190 may have an open opening 200 , and the open opening 200 is used to expose the substrate 140 away from the first side flange 150 and the second side flange 160 .

[0069] It is easy to understand that, by providing the opening 200 , the glass fiber reinforced composite material shell 190 can be deformed in this embodiment, so as to facilitate the assembly of the frame-shaped glass fiber inner ribs 180 and the glass fiber reinforced composite material shell 190 , thereby reducing the manufacturing difficulty.

[0070] In some specific embodiments of the present invention, the skeleton 120 may further include a foam glue 210 that wraps the glass fiber reinforced composite material profile 130 , and the foam glue 210 covers the substrate 140 and the gap between the glass fiber reinforced composite material profile 130 and the first profile 100 , and the gap between the glass fiber reinforced composite material profile 130 and the second profile 110 .

[0071] In some specific embodiments of the present invention, the foam glue 210 can be made of PET or PU foam, and the foam is filled in various gaps between the profile bodies to increase the structural strength of the profile bodies.

[0072] In some specific embodiments of the present invention, the PET foaming material can be a polyethylene terephthalate polymer with a molecular formula of (C10H8O4)n.

[0073] In some specific embodiments of the present invention, the PU foam material can be polyurethane foam mixed and filled with isocyanate and polyether or polyester polyol with a foaming agent and a catalyst through a glue injection machine.

[0074] Reference Figure 8 The present invention also provides a structural profile production method for producing the above-mentioned structural profile.

[0075] Briefly, the structural profile production method includes: passing the first side flange 150 through the first profile 100, passing the second side flange 160 through the second profile 110, and arranging the foam glue 210 between the first profile 100 and the second profile 110, the foam glue 210 covers the substrate 140 and the gap between the glass fiber reinforced composite material profile 130 and the first profile 100, and the gap between the glass fiber reinforced composite material profile 130 and the second profile 110.

[0076] for Figures 1 to 7 The structural profile production method includes a profile manufacturing part and a profile assembly part.

[0077] For the profile manufacturing part, the structural profile production methods include: Indoor and outdoor profile manufacturing step S001, through aluminum extrusion of a first profile 100 and a second profile 110, or, producing or purchasing a large square tube and a small square tube, opening the tube wall or corner of the large square tube, opening the tube wall of the small square tube, placing the small square tube in the large square tube, aligning the opening of the large square tube with the opening of the small square tube, and welding at the opening to fix the large square tube to the small square tube.

[0078] In the skeleton 120 profile manufacturing step S002, the glass fiber reinforced composite material is made into a glass fiber reinforced composite material profile 130 through a pultrusion process, or a glass fiber reinforced composite material rod is first processed using a mold and a pultrusion production line, and then bent through a mold to form a first side protrusion and a second side protrusion, and finally a glass fiber reinforced composite material profile 130 of a certain length is cut.

[0079] For the profile assembly part, the structural profile production method includes: In the profile assembly step S003, the gap between the first profile 100 and the second profile 110 is made to meet the needs of installing the frame 120, and the glass fiber reinforced composite material profile 130 is installed along the extension direction of the profile, so that the first side flange 150 of the glass fiber reinforced composite material profile 130 is inserted into the semi-enclosed groove 240 of the first profile 100, and the second side flange 160 of the glass fiber reinforced composite material profile 130 is inserted into the semi-enclosed groove 240 of the second profile 110, and the two glass fiber reinforced composite material profiles 130 are arranged in an I-shape.

[0080] In the glue coating and foaming step SOO4, a foam glue 210 is arranged between the first profile 100 and the second profile 110, and the foam glue 210 covers the substrate 140 and the gap between the glass fiber reinforced composite material profile 130 and the first profile 100, and the gap between the glass fiber reinforced composite material profile 130 and the second profile 110 to form a structural profile.

[0081] When practical application is required, the structural profiles can be connected to form the required energy-saving and thermal insulation profile system frame, and then the insulation panels and thermal insulation doors and windows can be installed between the profiles of the energy-saving and thermal insulation system frame to make the required ultra-low energy energy-saving and thermal insulation system. This system can be used for ultra-low energy and near-zero energy energy-saving buildings, ultra-low energy and near-zero energy mobile houses, cold chain transport insulated carriages, cold storage, refrigerated cabinets, vending cabinets, constant temperature containers, and thermal insulation doors and windows curtain walls, etc.

[0082] In addition, the structural profiles can be connected to form the required thermal insulation structure integrated structural profile system framework, which can include the four wall frames of the building, the building roof frame structure, and the building ground frame structure.

[0083] In some specific embodiments of the present invention, the connection nodes between the wall facade structure and the building roof structure, and the connection nodes between the wall facade structure and the building ground structure can be connected by setting steel angle codes inside the profile, and then using insulation panels and / or insulation doors and windows, the insulation panels and / or insulation doors and windows are installed in the insulation structure integrated structural profile system frame, so that a required ultra-low energy consumption insulation structure integrated thermal bridge-free structure system is formed between the profiles. The system can be used for ultra-low energy consumption and near-zero energy consumption energy-saving buildings, ultra-low energy consumption and near-zero energy consumption integrated mobile houses, cold chain transportation insulated carriages, cold storage, refrigerated cabinets, vending cabinets, constant temperature containers, etc.

[0084] When doors and windows need to be produced, the first profile 100 and the second profile 110 of the structural profile adopt the structural form of the door and window profile to form a door frame profile, a door leaf profile and a center support profile.

[0085] Therefore, the door and window profiles can be cut, connected at the corners, and formed into the required thermal insulation door and window profile system frame. After the frame is installed with glass, hardware, sealing strips and glass pressing lines, it forms an energy-saving door and window system. The system can be used for ultra-low energy consumption and near-zero energy consumption energy-saving buildings, and the exterior protective structure of ultra-low energy consumption and near-zero energy consumption buildings. The system has the advantages of high wind pressure resistance, good airtightness and watertightness, high energy-saving efficiency and low cost.

[0086] When a curtain wall needs to be produced, the first profile 100 and the second profile 110 of the structural profile adopt the structural form of the curtain wall profile to form a frame curtain wall profile, a unit curtain wall profile and a curtain wall beam profile.

[0087] Therefore, the curtain wall profiles can be cut and connected to form the required thermal insulation curtain wall profile system frame, and the frame is installed with glass, hardware, sealing strips and glass pressing lines to form an energy-saving building curtain wall system. The system can be used for ultra-low energy consumption and near-zero energy consumption energy-saving buildings, and the exterior protective structure of ultra-low energy consumption and near-zero energy consumption buildings. The system has the advantages of high wind pressure resistance, good airtightness and watertightness, high energy-saving efficiency and low cost.
