Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to a composite material profile, profile connectors, and their production methods and applications. Background Technology

[0002] Profiles are a type of long strip component. The cross-section of a profile is consistent along its length, and the cross-sectional profile is shaped during manufacturing to meet various installation requirements.

[0003] The performance of profiles largely depends on the material itself. For example, steel profiles are low in cost and high in strength, but heavy and not corrosion resistant; aluminum profiles are light in weight, moderate in strength, and not easily corroded, but expensive.

[0004] Meanwhile, steel and aluminum profiles are metal profiles with strong thermal conductivity, which is not conducive to energy saving and heat insulation.

[0005] Therefore, in the face of complex and varied realities, the selection of profiles is of great importance. If the wrong profiles are selected, it will affect the building's performance and lifespan, resulting in significant economic losses.

[0006] However, ordinary people do not have the relevant professional knowledge and are very prone to making mistakes when choosing profiles. At the same time, the various properties of existing profiles are not balanced or excellent, and they are difficult to meet the needs when the application environment or application requirements are more stringent. Summary of the Invention

[0034] The following description, in conjunction with the accompanying drawings, describes a composite material profile, profile connector, its manufacturing method, and its application according to embodiments of the present invention.

[0035] With social development and economic progress, various industries have emerged, especially the green and low-carbon economy, which has given rise to many new materials and processes in the construction and manufacturing industry.

[0036] Meanwhile, with the development of the photovoltaic industry, the application scenarios of photovoltaic brackets are becoming more and more complex. The original use of metal profiles such as steel or aluminum alloys can no longer meet the requirements of photovoltaic brackets for corrosion resistance, lightweight, and rigidity. Therefore, there is an urgent need for a high-strength, lightweight, and corrosion-resistant profile to meet market demand.

[0037] Meanwhile, with the development of the aquaculture and planting industries, aquaculture sheds are widely used, creating a great demand for high-strength, lightweight, and corrosion-resistant profiles.

[0038] As the goals of carbon peaking and carbon neutrality are advanced, energy conservation in doors, windows, and curtain walls becomes increasingly important. Door and window subframes and curtain wall profiles have high requirements for thermal insulation, demanding high structural strength, light weight, and good thermal insulation performance. However, the building components used to manufacture the aforementioned photovoltaic brackets, breeding sheds, doors, windows and curtain walls are mostly angle steel, channel steel or aluminum. These building components have significant performance differences and are difficult to meet various needs.

[0039] Reference Figures 1 to 4 The present invention aims to provide a composite material profile to overcome the problem of application defects caused by the large differences in various properties of existing profiles. It has the advantages of light weight, low density, good corrosion resistance, and low cost, and is easy to promote.

[0040] Similar to, Figures 1 to 4 All composite material profiles include an inner core 100 and an outer layer 110.

[0041] The outer layer 110 of the profile includes fiberglass material 120 and resin material. The fiberglass material 120 includes fiberglass fabric tubes and / or transverse fiber layers. The resin material is used to impregnate the fiberglass material 120 and connect the fiberglass material 120 to the inner core 100 of the profile.

[0042] When the fiberglass material 120 is a fiberglass fabric tube, the fiberglass fabric tube is fitted onto the outside of the profile inner core 100, and the resin material is used to impregnate the fiberglass fabric tube and connect the fiberglass fabric tube to the profile inner core 100.

[0043] When the glass fiber material 120 is a transverse fiber layer, the transverse fiber layer is wound around the outside of the profile core 100, and the resin material is used to impregnate the transverse fiber layer and connect the transverse fiber layer to the profile core 100. In summary, by setting the profile core 100, the present invention can improve the mechanical properties of the profile, such as strength, weight, and thermal insulation, by using a profile core 100 of a specific material or structure, thereby meeting the application requirements.

[0044] By setting the outer layer 110 of the profile, the present invention can protect the inner core 100 of the profile by using glass fiber material 120 and resin material, thereby preventing the inner core 100 of the profile from being corroded, making the profile durable, and reducing heat transfer to meet the needs of energy saving.

[0045] By applying glass fiber material 120 and resin material, this invention also ensures that the glass fiber material 120 is tightly attached to the inner core 100 of the profile, avoiding gaps between the outer layer 110 of the profile and the inner core 100 of the profile. This not only prevents foreign objects such as corrosive substances from entering and provides long-term protection for the inner core 100 of the profile, but also facilitates the connection of components and prevents loosening.

[0046] Reference Figure 1 In some specific embodiments of the present invention, the outer layer 110 of the profile may include longitudinal continuous glass fiber 130, which is located between the glass fiber material 120 and the inner core 100 of the profile. The longitudinal continuous glass fiber 130 extends along the extension direction of the profile, and the resin material is used to impregnate the longitudinal continuous glass fiber 130 and connect the glass fiber material 120 and the inner core 100 of the profile.

[0047] It is easy to understand that in this embodiment, by setting longitudinal continuous glass fibers 130, continuous glass fibers extending along the extension direction of the profile are also set, and the continuous glass fibers are distributed along the outer contour of the inner core 100 of the profile. Therefore, the continuous glass fibers are also used to improve the bending resistance and flexibility of the profile.

[0048] Meanwhile, during the manufacturing process, the longitudinal continuous glass fiber 130 can also be used for traction in pultrusion molding, making it easier for the glass fiber material 120 to enter the pultrusion mold.

[0049] In some specific embodiments of the present invention, longitudinal continuous glass fibers 130 can be used to fill the gap between the glass fiber material 120 and the profile core 100. That is, the longitudinal continuous glass fibers 130 are distributed along the outer contour of the profile, thereby adapting to situations where there is a difference between the shape of the glass fiber material 120 and the shape of the profile core 100.

[0050] In some specific embodiments of the present invention, the fiberglass fabric tube or continuous glass fiber may include glass fiber, basalt fiber or carbon fiber.

[0051] It is easy to understand that this embodiment uses glass fiber, basalt fiber or carbon fiber to manufacture glass fiber fabric tubes and continuous glass fiber, which are easy to obtain and convenient to manufacture. At the same time, the sources of materials are diversified, reducing the manufacturing difficulty and manufacturing cost.

[0052] In some specific embodiments of the present invention, the resin material may include polyurethane resin, epoxy resin, ethylene resin, unsaturated resin, light-curing resin, PA resin, PP resin or PE resin.

[0053] It is easy to understand that by using the above-mentioned resin, this embodiment can improve the acid resistance, alkali resistance, and oxidation resistance in a targeted manner while meeting the requirements of corrosion resistance, so as to meet the needs of extreme environments.

[0054] Reference Figure 2 In some specific embodiments of the present invention, the cross-section of the profile core 100 can be a semi-closed shape such as a U-shape, which not only has high strength, but also facilitates the installation of mounting structures inside the profile core 100 to meet installation needs, while reducing or even avoiding damage to the outer layer 110 of the profile and preventing local exposure that could lead to corrosion of the composite material profile. (Refer to...) Figure 3 In some specific embodiments of the present invention, the profile core 100 can be hollow, which helps to reduce weight and manufacturing costs.

[0055] Reference Figure 1 and Figure 3 In some specific embodiments of the present invention, the outer contour of the profile core 100 may be provided with recesses 160 or protrusions for connection.

[0056] It is easy to understand that by setting recesses 160 or protrusions, the slots or clips required for installation can be prefabricated in this embodiment, which facilitates assembly by inserting the clips, reduces the use of screws, and avoids damage to the outer layer 110 of the profile.

[0057] In some specific embodiments of the present invention, the profile core 100 may include a steel profile, an aluminum profile, or a glass fiber reinforced pultruded profile 150.

[0058] It is easy to understand that by using profile cores 100 made of different materials, this embodiment can meet different mechanical performance requirements, while taking into account weight, cost and energy-saving insulation.

[0059] Reference Figure 4 In some specific embodiments of the present invention, the profile core 100 may include at least two first metal profiles 140 and a glass fiber reinforced pultruded profile 150 connecting the two first metal profiles 140.

[0060] It is easy to understand that by setting the glass fiber reinforced pultruded profile 150 in this embodiment, heat transfer between the two first metal profiles 140 can also be reduced, which helps to save energy and heat insulation.

[0061] In use, the composite material profile of this embodiment can be used as a composite material profile connector for building curtain walls, used to connect the column profile of the curtain wall and the glass pressure plate to form a thermal insulation profile. The profile connector is provided with a sealing strip groove, and generally two or more grooves are provided. The purpose of this invention is to produce a composite material profile connector for building curtain walls that meets the requirements of thermal insulation while satisfying the horizontal and vertical structural strength of the curtain wall, reducing heat conduction between indoor and outdoor aluminum alloy profiles, and achieving the purpose of energy saving and consumption reduction.

[0062] In use, the composite material profile of this embodiment can be used as a composite material bracket profile for new energy photovoltaic power generation, used for connection and fixation between photovoltaic bracket columns and photovoltaic modules. The profile adopts a "C" shaped cross-section structure and has the characteristics of high strength, light weight, low cost, good corrosion resistance, wide application scenarios, and long service life.

[0063] In use, the composite material profile of this embodiment can be used as a photovoltaic frame profile for photovoltaic power generation, for connecting and fixing photovoltaic glass. The profile adopts a combination structure of metal aluminum alloy profile core and composite material profile, which has the characteristics of high strength, light weight, low cost, good corrosion resistance, energy saving and heat preservation. It has a wide range of applications, long service life, and can avoid corrosion after long-term use.

[0064] Reference Figure 5 The present invention also aims to provide an embodiment of a composite material profile connector.

[0065] The composite material profile connector may include two frame-shaped connecting profiles 170, two C-shaped steel profiles 180, and a second metal profile 190. The two C-shaped steel profiles 180 and the second metal profile 190 engage with the two frame-shaped connecting profiles 170, so that the two frame-shaped connecting profiles 170 are set back to back and attached to each other to form a profile connector.

[0066] In some specific embodiments of the present invention, the two frame-shaped connecting profiles 170 can be formed by axially cutting a hollow composite material profile.

[0067] Reference Figure 6 The present invention also aims to provide another embodiment of a composite material profile connector.

[0068] In some specific embodiments of the present invention, the composite material profile connector may include a first metal profile 140, which connects the inner sides of two frame-shaped connecting profiles 170, such that the inner sides of the two frame-shaped connecting profiles 170 are arranged opposite to each other.

[0069] Accordingly, one of the frame-shaped connecting profile 170 and the first metal profile 140 is provided with a limiting rib for passing through, and the other of the frame-shaped connecting profile 170 and the first metal profile 140 is provided with a passing groove for the limiting rib to pass through.

[0070] In some specific embodiments of the present invention, expanding foam can be used to fill the gaps in the composite profile connectors.

[0071] In some specific embodiments of the present invention, rivets can be used to connect the components, reducing relative movement.

[0072] In use, the composite material profile connector of this embodiment can be used as an integrated composite material profile for building insulation structure, used in the external envelope structure of ultra-low energy consumption buildings, mainly replacing the building steel of ultra-low energy consumption buildings. The profile adopts a composite structure of metal and composite material profiles, which has the characteristics of high strength, light weight, low cost, good thermal insulation performance and energy saving. It has a wide range of applications, long service life, and realizes the thermal bridge-free structure and prefabricated construction of building external envelope.

[0073] Reference Figure 7 The present invention also aims to provide another embodiment of a composite material profile connector.

[0074] Among them, the composite material profile connector includes a hollow composite material profile. At the same time, an inner steel 200 is inserted into the interior of the composite material profile, and an outer steel 210 is fitted on the outside of the composite material profile. The outer steel 210 is hollow or is made of at least two steel pieces spliced ​​together.

[0075] In some specific embodiments of the present invention, expanding foam can be used to fill the gaps in the composite profile connectors.

[0076] In some specific embodiments of the present invention, rivets can be used to connect the components, reducing relative movement.

[0077] Reference Figure 8 The present invention also aims to provide a method for producing composite material profile connectors, wherein the method for producing composite material profile connectors includes a composite material profile manufacturing part and a composite material profile post-processing part, and the composite material profile manufacturing part includes a profile inner core manufacturing part and a composite material profile generation part.

[0078] Therefore, the present invention also aims to provide an embodiment of a method for producing the inner core of a composite material profile, and at the same time, the present invention also aims to provide an embodiment of a method for producing a composite material profile.

[0079] At the same time, refer to Figure 9The present invention is intended to provide a schematic diagram of a production equipment for applying the above-described production method.

[0080] The production method of the inner core of composite profiles mainly includes the inner core manufacturing steps.

[0081] Since the profile core 100 has a form, it can be manufactured in the following ways.

[0082] When the inner core 100 of the profile is made of aluminum profile or thermoplastic material, the inner core 100 of the profile can be formed by extrusion process.

[0083] When the inner core 100 of the profile is made of steel, the inner core 100 of the profile can be formed by cold rolling of steel strip.

[0084] When the profile core 100 is composed of multiple parts, each part can be manufactured separately and then assembled.

[0085] In some specific embodiments of the present invention, the profile core 100 may include two first metal profiles 140 and at least one first non-metal profile, such as a glass fiber reinforced pultruded profile 150. The two first metal profiles 140 are connected by the first non-metal profile to form the profile core 100. Figure 4 As shown.

[0086] The first metal profile 140 can be an aluminum profile, steel profile, etc., while the first non-metal profile can be a glass fiber reinforced composite profile to meet the requirements of strength and energy-saving insulation.

[0087] At the same time, after the inner core 100 of the profile is manufactured, it can be cut so that the length of the inner core 100 meets the processing requirements of subsequent processes.

[0088] After the inner core 100 of the profile is manufactured, the composite material profile generation part can be carried out. The composite material profile generation part mainly includes the coating step and the pultrusion molding step.

[0089] Specifically, in the coating step, the profile core 100 and the longitudinal continuous glass fiber 130 are passed through the glass fiber material forming equipment 220 and the pultrusion forming equipment 230 and fixed by the traction belt of the pultrusion forming equipment 230. The glass fiber material forming equipment 220 weaves or winds the glass fiber material 120 to the outside of the profile core 100 and the longitudinal continuous glass fiber 130.

[0090] In the pultrusion process, a traction belt feeds the glass fiber material 120, the profile core 100, and the longitudinal continuous glass fiber 130 into the pultrusion molding equipment. At the same time, the longitudinal continuous glass fiber 130 fills the gap between the glass fiber material 120 and the profile core 100. Then, after impregnation and heat curing, a composite material profile is formed.

[0091] In detail, when the fiberglass material 120 is a fiberglass braided tube, firstly, according to the design, calculate the outer perimeter of the exposed part of the product connector profile, then subtract the thickness of the fiberglass braided tube, calculate the perimeter of the tubular forming mold of the fiberglass braided tube, then make the tubular mold, the tubular mold is used for braiding the tube, and the tubular forming mold is installed at the axis position of the fiberglass tube braiding machine to complete the fixation.

[0092] Next, the completed pultrusion mold is installed on the mold setting table of the pultrusion production line, and the mold of the pultrusion production line is placed behind the braiding machine.

[0093] Then, the continuous glass fiber is inserted into the hollow part of the tubular forming mold of the glass fiber braided tube, and then into the pultrusion forming mold. Generally, a portion of the continuous glass fiber is arranged first, and after passing through the pultrusion mold, it is connected and fixed with a traction belt.

[0094] Finally, start the braiding machine to braid the fiberglass tube, and then insert the fiberglass tube into the pultrusion mold. At the protrusion point inside the mold at the groove of the product profile inside the pultrusion mold, use a special tool to smoothly and evenly guide the fiberglass tube into the pultrusion mold.

[0095] If necessary, continuous glass fibers are inserted into the inside of the fiberglass braided tube to fill the gap between the fiberglass braided tube and the original continuous fibers inside the mold, so as to extrude and form it in the mold.

[0096] Then, resin is injected into the injection box of the pultrusion mold. The resin is then immersed in the glass fiber braided tube and then into the interior of the continuous glass fiber. Finally, the pultrusion mold is heated, cured, and molded to produce a composite material profile.

[0097] When the profile core 100 is made of steel, the steel strip roller pressing line can be arranged on the side of the braiding machine away from the pultrusion production line to realize the in-line production of the profile core 100, the glass fiber material 120 and the composite material profile.

[0098] In detail, when the glass fiber material 120 is a transverse fiber layer, a winding forming device is used instead of a braiding machine. Then, continuous glass fiber is wound around the outer surface of the profile core 100. During winding, the transverse continuous fiber forms an angle of less than 90 degrees with the axial direction or length direction of the profile core 100. While the profile core 100 moves forward, the glass fiber winding device drives the glass fiber to be wound around the pultruded profile.

[0099] Then, it is pultruded in a pultrusion die. When the inner core 100 is also a pultruded profile, the production line of the inner core 100 can be arranged at the beginning of the line, thereby realizing continuous production.

[0100] After the composite profile is manufactured, the post-processing of the composite profile can be carried out, thereby completing the production of the composite profile connectors. The post-processing of the composite profile mainly includes the connector preparation steps.

[0101] For hollow composite material profiles, the hollow composite material profiles are axially cut to form two frame-shaped connecting profiles 170. The frame-shaped connecting profiles 170 form profile connectors. The two ends of the cross section of the frame-shaped connecting profiles 170 are used for connection and installation to meet the usage requirements.

[0102] In some specific embodiments of the present invention, two C-shaped steel members 180 can be used to engage two frame-shaped connecting profiles 170, so that the two frame-shaped connecting profiles 170 are back-to-back and fitted together to form a profile connector to meet the usage requirements. See details below. Figure 5 .

[0103] In some specific embodiments of the present invention, rivets can be anchored to improve the connection strength and achieve reinforcement.

[0104] In some specific embodiments of the present invention, a second metal profile 190 can be used to connect the inner sides of two frame-shaped connecting profiles 170, so that the inner sides of the two frame-shaped connecting profiles 170 are arranged opposite each other to meet different usage needs. See details below. Figure 6 .

[0105] In some specific embodiments of the present invention, a rolling process can be used to reduce the connection gap, improve the connection strength, and reduce the risk of detachment.

[0106] For hollow composite profiles, there are other ways to prepare the connectors. For example, an inner steel member 200 can be inserted inside the hollow composite profile, and an outer steel member 210 can be fitted onto the outside of the composite profile. The outer steel member 210 can be hollow or composed of at least two steel members spliced ​​together. See the following for details. Figure 7 .
