Description

Technical Field

[0001] The invention belongs to the field of thermally-insulated aluminum alloy door and window systems, and particularly relates to a core material, a composite profile, a door and window frame, and a manufacturing method thereof. Background Art

[0002] As living standards continue to improve, people's demands for better lighting in their homes are also increasing. Windows in both ordinary homes and high-rise buildings are becoming larger, and the ratio of windows to the building's surface area is constantly increasing. Window frames are common components in all types of buildings. Traditional aluminum alloy window frame profiles have excellent heat transfer properties and have become the primary channel for heat transfer between indoors and outdoors. This easily transfers heat or cold from indoors to the outdoors, significantly affecting indoor temperatures. This has led to the emergence of thermal break windows. Thermal break windows utilize thermal break profiles to create the frame. Insulating core material or strips are inserted between the decorative profiles, creating a thermal break that enhances insulation.

[0003] The core material structure of traditional thermally insulated aluminum alloy door and window systems is complex, lacking precision and making installation difficult. Furthermore, the core material's insufficient strength in wide core structures results in poor dimensional accuracy, insufficient structural rigidity, and unreliable performance. Furthermore, traditional thermally insulated aluminum alloys fail to meet the fire protection requirements of fire protection design codes. Thermal insulation doesn't provide fire protection, and fire protection doesn't provide energy savings. Striking a perfect balance between the two is a challenge. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a core material, a composite profile, a door and window frame, and a manufacturing method thereof.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows:

[0006] On the one hand, the present invention discloses a core material, wherein each of the two sides of the core material has at least one surface, and the parallelism between them is no more than 0.3MM. The side of the core material has at least one cantilever, and the parallelism between at least one surface of the cantilever and at least one surface of the other side is no more than 0.3MM. The core material is made of continuous fiber reinforced composite material, and the fiber content is not less than 40% by weight.

[0007] The present invention discloses a core material, the strength of which is far higher than that of existing polyamide insulation profiles and polyurethane cast insulation profiles. Since the side surfaces of the core material are specially processed, the flatness accuracy is much higher than that of existing insulation profiles, the dimensional accuracy of all composite profiles is greatly improved, and the accuracy of door and window frames composed of this composite profile is guaranteed.

[0008] On the basis of the above technical solution, the following improvements can be made:

[0009] As a preferred solution, at least one cantilever is provided on both sides of the core material, and the parallelism of at least one surface on the cantilever on the two sides with at least one side surface of at least one cantilever on the other side is not greater than 0.3MM.

[0010] By adopting the above-mentioned preferred scheme, the cantilever on the side of the core material can be compounded with other profiles. According to the above-mentioned principle, since the side of the cantilever and the side of the core material have a highly parallel plane, the dimensional accuracy of the composite profile obtained after compounding with this core material is guaranteed, thereby achieving the above-mentioned technical effect.

[0011] As a preferred solution of the core material, at least one side portion of the core material and / or an end portion of a cantilever on at least one side portion is concave.

[0012] By adopting the above-mentioned preferred scheme, on the one hand, the molding mold line of the core material can be arranged in the depression, which avoids destroying the parallelism accuracy of the fitting surface of the core material side and other profiles when compounding with other profiles, and can also reduce the processing area when processing and grinding the core material side, thereby improving efficiency and processing accuracy; furthermore, after compounding with other profiles, a multi-cavity structure can be formed to enhance its thermal insulation performance.

[0013] As a preferred solution for the core material, one side of the cantilever has a notch arranged along the length direction of the core material.

[0014] With the above preferred solution, the notch is used to be assembled with the first profile or the second profile to form a composite profile.

[0025] By adopting the above preferred solution, the thermal insulation and fire prevention effects of the door and window frames made of the core material are further improved.

[0026] As a preferred embodiment of the core material, the reinforcing material in the core material comprises glass fiber, the glass fiber comprises continuous glass fiber and glass fiber products, and the glass fiber products comprise one or more combinations of the following: glass fiber fabric, mat, cloth, composite mat;

[0027] The weight of the glass fiber product is not less than 8% by weight of the glass fiber.

[0028] By adopting the above preferred solution, the core material has high mechanical strength, especially the transverse strength of the core material perpendicular to the fiber direction is greatly improved. At the same time, due to the wrapping of the glass fiber fabric, the core material remains a whole during combustion, and the fire resistance of the core material is greatly improved.

[0029] On the other hand, the present invention also discloses a composite profile, which includes: any of the above core materials and a first profile and a second profile respectively arranged on both sides of the core material, and the two side portions of the core material are respectively clamped with the first profile and the second profile.

[0030] As a preferred solution for the composite profile, the first profile and / or the second profile has a slot and a foot, the core material cantilever is placed in the slot of the first profile or the second profile, and at least one side of the core material is in close contact with the inner wall of the slot of the first profile or the second profile.

[0031] By adopting the above preferred solution, the composite process is efficient, the connection is more firm, and the composite size is more precise.

[0032] As a preferred solution for the composite profile, at least a portion of the clamping foot is placed in the core material groove and is clamped with at least one wall in the groove.

[0033] By adopting the above preferred solution, the profile and the core material can be positioned and fixed by the relative position and mutual extrusion of the clamping feet and the inner wall of the groove, so that the connection is more firm and the composite size is more accurate.

[0034] As a preferred solution of the composite profile, glue is injected into at least one groove engaged with the clamping foot.

[0035] By adopting the above preferred solution, the notch and the clamping foot are bonded and / or sealed to each other, which not only enhances the composite strength of the profile and the core material, but also ensures the sealing of the clamping surface.

[0036] As a preferred solution of the composite profile, at least one portion of the clamping foot can be pressed and rotated.

[0037] By adopting the above preferred solution, at least a portion of the clamping foot can be squeezed and rotated to engage with the inner wall of the slot, so that the clamping foot can easily penetrate the slot and clamp the core material through the inner wall of the slot under the action of squeezing.

[0038] As a preferred solution of the composite profile, the end of at least one clamping foot on the second profile has a protrusion, and the protrusion is in close contact with the inner wall of the groove on the core material.

[0039] With the above preferred solution, the protrusion is in close contact with the inner wall of the notch on the core material, so that the corresponding side of the core material is in close contact with the inner wall of the slot on the second profile.

[0040] As a preferred solution for the composite profile, the inner wall of the notch in contact with the protrusion is an inclined surface that forms an angle with the inner wall of the slot of the second profile.

[0041] By adopting the above preferred solution, the clamping foot applies a clamping force toward the profile slot and the center of the core material at the same time through the oblique surface, so that the clamping foot can hold the core material tightly while fitting the core material and the inner wall of the profile slot tightly, thereby ensuring the composite accuracy and firmness.

[0042] As a preferred solution for the composite profile, one side surface of at least one foot of the second profile has at least two surfaces, wherein one surface close to the tip of the foot is a polished surface, which contacts the glue injected into the groove.

[0043] With the above preferred solution, the polished surface is glued after the glue is injected to improve the bonding strength.

[0044] As a preferred solution for the composite profile, at least one clip on the first profile has a first section and a second section close to the end, the first section and the second section are in contact with the first inner wall and the second inner wall of the slot respectively, the end point of the second section has a gap with the lower wall of the slot, and the inner wall of the second section is in contact with a straight surface parallel to the second inner wall of the slot to which the core material is clipped, and can slide down along the straight surface.

[0045] As a preferred solution for the composite profile, after the first profile is clamped with the core material, there is a gap of no less than 0.2 mm between the top or bottom of the first profile's clamping groove and the top or bottom of the core material cantilever.

[0046] As a preferred solution for the composite profile, there is a recessed section between the starting point of the first section and the end point of the second section of the clip, and the minimum thickness of the recessed section is between 0.2MM and 1MM, ensuring that the first section of the clip rotates along the recess when squeezed in the slot, and that slippage can occur between the first profile and the core material during thermal expansion and contraction, thereby ensuring that the entire window will not be deformed due to the different thermal expansion and contraction of the profile and the core material.

[0047] By adopting the above-mentioned preferred scheme, the clamping foot can easily pass through the core material groove, and the core material can be centered in the groove between the clamping feet. The first section is engaged with the first inner wall of the groove. When the clamping foot is squeezed, the first section of the clamping foot rotates along the depression of its starting section, thereby pushing the second section in reverse to extrude the straight surface of the second inner wall of the groove, so that the side surface of the core material and the inner wall of the profile groove between the clamping foot fit tightly, ensuring the composite accuracy and firmness. When the profile needs to slide up and down with the core material due to thermal expansion and contraction, sliding can also be achieved without affecting the straightness and firmness of the composite profile. The minimum thickness of the recessed section is controlled at 0.2-1MM to ensure that the first section can rotate when the profile needs to slide up and down with the core material due to thermal expansion and contraction. The front end of the first section is in contact with the bottom of the core material groove to ensure that the glue does not flow into the cavity of the second section, ensuring that the second section can slide up and down.

[0048] On the other hand, the present invention also discloses a profile composite method for installing any of the above composite profiles, comprising the following steps:

[0052] As a preferred solution of the profile composite method, it also includes the step of injecting glue into the core material groove.

[0053] By adopting the above preferred solution, the notch and the clamping foot are bonded or sealed to each other.

[0054] As a preferred solution of the profile composite method, the following step is also included: before rolling the clamping foot of the second profile, the side of the clamping foot that contacts the glue is ground.

[0055] With the above preferred solution, the polished surface is glued after the glue is injected to improve the bonding strength.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0088] At the same time, expressions such as “first” and “second” are only used to distinguish multiple configurations, rather than to limit the order between configurations or other features.

[0089] In addition, the expression “including” an element is an “open” expression, which simply means that corresponding components exist and should not be interpreted as excluding additional components.

[0090] In order to achieve the purpose of the present invention, a core material, a composite profile, a door and window frame and some embodiments of their manufacturing methods are provided.

[0091] like Figure 1-3 As shown, on the one hand, an embodiment of the present invention discloses a core material, wherein the two side portions 12 of the core material 1 each have at least one surface, and the mutual parallelism between them is not greater than 0.3MM, and the side portion 12 of the core material 1 has at least one cantilever 11, and the parallelism between at least one surface of the cantilever 11 and at least one surface of the other side portion 12 is not greater than 0.3MM, and the core material 1 is made of continuous fiber reinforced composite material, and the fiber content is not less than 40% by weight.

[0092] The present invention discloses a core material 1, the strength of which is far higher than that of existing polyamide insulation profiles and polyurethane cast insulation profiles. Since the side portions 12 of the core material are specially processed, the parallel flatness accuracy between them is much higher than that of existing insulation profiles, so the dimensional accuracy of the composite profile is greatly improved, and the accuracy of door and window frames composed of this composite profile is guaranteed.

[0093] In order to further optimize the implementation effect of the present invention, in some other embodiments of the core material, the other characteristic technologies are the same, the difference is that both side portions 12 of the core material 1 are provided with at least one cantilever 11, and at least one surface on the cantilever 11 on the two side portions 12 has a parallelism of no more than 0.3MM with at least one side surface on at least one cantilever 11 on the other side portion 12.

[0094] By adopting the above-mentioned preferred scheme, the cantilever 11 on the side of the core material can be compounded with other profiles. According to the above-mentioned principle, since there are planes with high parallelism between the side of the cantilever 11 and the side 12 of the core material 1, the dimensional accuracy of the composite profile obtained after compounding with this core material is guaranteed, thereby achieving the above-mentioned technical effect.

[0096] By adopting the above preferred solution, on the one hand, the mold line of the core material 1 can be arranged in the concave portion 12 of the side portion 12 of the core material 1, which avoids damaging the parallelism accuracy of the core material side and the contact surface of the other profiles when compounding with other profiles, and can also reduce the processing area when machining and grinding the side of the core material 1, thereby improving efficiency and processing accuracy. Furthermore, after compounding with other profiles, a multi-cavity structure can be formed to enhance its thermal insulation performance.

[0097] In order to further optimize the implementation effect of the present invention, in some other embodiments of the core material, the other characteristic technologies are the same, except that a notch 13 arranged along the length direction of the core material 1 is provided on one side of the cantilever 11 .

[0112] The above preferred embodiment provides a core material with high mechanical strength. In particular, the core material's transverse strength perpendicular to the fiber direction is significantly enhanced, while also significantly improving its thermal insulation and / or fire resistance. Furthermore, due to the glass fiber fabric wrapping, the core material remains intact during combustion, significantly enhancing its fire resistance.

[0113] On the other hand, the present invention also discloses a composite profile, which includes: any of the above core materials 1 and a first profile 2 and a second profile 3 respectively arranged on both sides of the core material 1, and the two side portions of the core material 1 are respectively clamped with the first profile 2 and the second profile 3.

[0117] Using the above preferred solution, the profile and core material can be positioned and fixed by the relative position and mutual compression between the clamping feet 6 and the inner wall of the notch 13, resulting in a more secure connection and more precise composite dimensions. To further optimize the implementation effect of the present invention, in other embodiments of the composite profile, the remaining technical features are the same, except that glue 7 is injected into at least one notch 13 that engages with the clamping feet.

[0118] By adopting the above preferred solution, the notch 13 and the clamping foot 6 are bonded and / or sealed to each other, which not only enhances the composite strength of the profile and the core material, but also ensures the sealing of the clamping surface.

[0119] In order to further optimize the implementation effect of the present invention, in some other embodiments of the composite profile, the remaining characteristic technologies are the same, except that at least a portion of the clamping foot 6 can be squeezed and rotated.

[0120] By adopting the above preferred solution, at least a portion of the clamping foot 6 can be squeezed and rotated to engage with the inner wall of the slot 13, so that the clamping foot can easily penetrate the slot 13 and clamp the core material 1 through the inner wall of the slot 13 under the action of squeezing.

[0121] In order to further optimize the implementation effect of the present invention, in some other embodiments of the composite profile, the remaining characteristic technologies are the same, except that the end of at least one clip 6 on the second profile 3 has a protrusion 8, and the protrusion 8 is in close contact with the inner wall of the groove 13 on the core material.

[0123] In order to further optimize the implementation effect of the present invention, in some other embodiments of the composite profile, the remaining characteristic technologies are the same, except that the inner wall of the notch 13 in contact with the protrusion 8 is an inclined surface that forms an angle with the inner wall of the slot 5 of the second profile 3.

[0124] By adopting the above-mentioned preferred solution, the clamping foot 6 applies a clamping force toward the clamping groove 5 of the second profile 3 and the center of the core material 1 to the core material 1 at the same time through the inclined surface, so that the clamping foot 6 can hold the core material 1 tightly while fitting the core material 1 tightly to the inner wall of the clamping groove 5 of the second profile 3, thereby ensuring the composite accuracy and firmness.

[0125] As a preferred solution for the composite profile, one side surface of at least one foot of the second profile 3 has at least two surfaces, wherein one surface close to the tip of the foot is a polished surface, which contacts the glue injected into the groove.

[0126] With the above preferred solution, the polished surface is glued after the glue is injected to improve the bonding strength.

There is a gap between the end point of the second section 62 and the lower wall of the slot 13, and the inner wall of the second section is in contact with a straight surface parallel to the second inner wall of the slot where the core material is clamped, and can slide down along the straight surface.

[0128] In order to further optimize the implementation effect of the present invention, in some other embodiments of the composite profile, the other characteristic technologies are the same, the difference is that after the first profile 2 is clamped with the core material 1, there is a gap of no less than 0.2MM between the top or bottom of the first profile slot and the top or bottom of the core material cantilever 11.

[0129] In order to further optimize the implementation effect of the present invention, in some other embodiments of the composite profile, the remaining characteristic technologies are the same, except that there is a recessed section 63 between the starting point of the first section 61 of the clamping foot and the end point of the second section 62, and the minimum thickness of the recessed section 63 is between 0.2MM and 1MM. When the first section 61 of the clamping foot is squeezed in the groove 13, it rotates along the recess 63.

[0130] When the clamping foot 6 is squeezed, the first section 61 of the clamping foot rotates along the recess 63 of its starting section, thereby pushing the second section 62 in the opposite direction to squeeze the straight surface of the second inner wall of the groove 13, so that the side of the core material 1 and the inner wall of the profile groove between the clamping foot 6 fit tightly, ensuring composite accuracy and firmness. At the same time, the first section 61 is in close contact with the first inner wall of the groove 13, so that the injected glue cannot fill the bottom of the groove 13. When the first profile 2 needs to slide up and down with the core material 1 due to thermal expansion and contraction, it can achieve sliding without affecting the firmness of the composite profile. The minimum thickness of the recessed section is controlled at 0.2-1MM to ensure that the first section can rotate when the profile needs to slide up and down with the core material due to thermal expansion and contraction. The front end of the first section contacts the bottom of the core groove, preventing the glue from flowing into the cavity of the second section and allowing the second section to slide up and down. The first section of the foot, when squeezed within the notch, rotates along the depression. During thermal expansion and contraction, the first profile and the core material can slide, thereby preventing the entire window from deforming due to the differential thermal expansion and contraction between the profile and the core material.

[0131] like Figure 13 As shown, on the other hand, the present invention also discloses a profile composite method for installing the composite profile disclosed in any of the above embodiments, comprising the following steps:

[0132] 1) Grind both sides of the core material 1 so that at least one side surface of the core material 1 is parallel to the other side surface, and the parallelism is not greater than 0.3MM;

[0133] 2) Place the side portion 12 of the core material in the slot 3 of the first profile 2 and / or the second profile, as shown in FIG. Figure 4 As shown;

[0134] 3) Roll at least one of the feet 6 of the first profile 2 and / or the second profile 3 so that it rotates and fits against the inner wall of the core material slot 13, and the side portion 12 of the core material 1 fits against the inner wall of the first profile and / or the second profile slot 5, as shown in FIG. Figure 5 shown.

[0135] In order to further optimize the implementation effect of the present invention, in some other embodiments of the profile composite method, the remaining characteristic technologies are the same, except that it also includes a step of injecting glue into the core material notch 13.

[0136] By adopting the above preferred solution, the notch 13 and the clamping foot are bonded or sealed to each other.

[0140] By adopting the above preferred solution, the efficiency and accuracy of the composite of the profiles 2, 3 and the core material 1 can be greatly improved, while the core material 1 can be firmly connected with other fasteners through the insert 9 in the slot 15 in the cavity 14 thereof, and the process flexibility of the profile filling can be achieved.

[0144] 2) Impact the corners of the profiles where the profile angle brackets are placed to deform them together and thus fasten them together.

[0146] By adopting the above preferred solution, adjacent core materials are spliced together, and existing aluminum alloy corner assembly equipment can be used, so that the corner assembly efficiency and reliability are guaranteed.
