Description

Technical Field

[0001] This invention relates to the field of door and window profile technology, and in particular to a variable-shape thermal break core structure. Background Technology

[0002] Currently, composite profiles are widely used in doors and windows in the construction industry. Various profile shapes enable precise fitting between the glass and frame, achieving heat insulation, sound insulation, and energy-saving effects. Existing door and window profiles are manufactured in the factory and then modularly assembled to facilitate installation due to different pre-drilled installation openings or user needs. However, traditional door and window profiles have a relatively simple structure; after factory processing, only the length can be adjusted, not the width or height, making modular assembly impossible based on the size and shape of the opening on-site, resulting in limited applicability.

[0003] Existing technology, such as the Chinese utility model patent with publication number CN205477138U and publication date of August 17, 2016, discloses an aluminum alloy corner profile, including an arc-shaped cover plate with a 45° centerline symmetrical structure, a pair of outer corners and an inner corner connected to both ends of the arc-shaped cover plate by a snap-fit ​​device, and an arc-shaped support plate with a 45° centerline symmetrical structure and thermal insulation strips disposed at both ends of the arc-shaped support plate. The outer corners and the thermal insulation strips are connected by snap-fit ​​connections, and the thermal insulation strips are connected to both ends of the inner corners by snap-fit ​​connections. Although this patent, by setting up an arc-shaped support plate and thermal insulation strips, makes the outer and inner corner structures simple, easy to assemble and disassemble, and sturdy and reliable, its function is limited to the assembly of 90° corners. For existing door and window profile structures that need to be installed, it is not possible to adjust the splicing of the profiles or make adaptive modifications according to the structure to be installed. Summary of the Invention

[0004] To address the shortcomings of the aforementioned background technology, this invention proposes a variable-shape thermal break core structure, which solves the problem in the prior art where door and window profiles are fixed and cannot be modified according to the actual shape.

[0005] The technical solution of the present invention is implemented as follows: a variable-shape thermal break core structure, including an indoor side structure and an outdoor side structure, both the indoor side structure and the outdoor side structure are provided with corresponding heat insulation strips. The indoor side structure is connected to the outdoor side structure through the heat insulation strips to form a frame structure. Both the indoor side structure and the outdoor side structure include two symmetrically arranged thermal break columns. The thermal break columns are connected with heat insulation strips, and the two thermal break columns are connected through the heat insulation strips.

[0006] More preferably, the thermal break column is an isosceles trapezoidal structural profile, with a groove 1 on one side of the isosceles trapezoidal structural profile that cooperates with the second heat insulation strip, and a groove 2 on the other side of the isosceles trapezoidal structural profile that cooperates with the first heat insulation strip, and a splicing cover is fastened to the isosceles trapezoidal structural profile.

[0007] More preferably, the cover is an arc-shaped cover, and the inner side of the arc-shaped cover is provided with an L-shaped fastening strip, which is fastened to the retaining flange at the bottom of the isosceles trapezoidal structural profile.

[0008] More preferably, the cover is a right-angle cover, and fasteners are provided at both ends of the right-angle cover. The fasteners are engaged with the snap-fit ​​flanges provided at the bottom of the isosceles trapezoidal structural profile.

[0009] More preferably, the splice cover is a wide splice cover, and the wide splice cover is provided with two fastening grooves, which are respectively fastened to the corresponding broken bridge column.

[0010] More preferably, the cover includes wing panels, with a small cover plate fastened to the wing panels, and a flat cover plate between two adjacent wing panels. The flat cover is installed between the indoor side structure and the outdoor side structure.

[0011] More preferably, the thermal break column on the outdoor side structure includes a frame-type column profile one, two adjacent frame-type column profiles one are connected by a thermal break strip two, a glass clamp is connected to the frame-type column profile one, and a wide cover plate is provided between two adjacent glass clamps; the thermal break column on the indoor side structure includes a frame-type column profile two, two adjacent frame-type column profiles two are connected by a thermal break strip two, a flat cover plate is provided between two frame-type column profiles two, and the frame-type column profile one is connected to the frame-type column profile two by a thermal break strip one.

[0012] In a further preferred embodiment, the broken bridge column includes a frame-type column profile three, with wing plates provided on both adjacent sides of the frame-type column profile three, and a right-angle cover plate fastened between the two wing plates.

[0013] More preferably, an insulating set screw is connected to the wing plate, and the insulating set screw is arranged parallel to the heat insulation strip.

[0014] More preferably, a reinforcing liner is installed inside the frame structure. The reinforcing liner is a cylindrical liner, and a protective sleeve is fitted on the outer wall of the cylindrical liner. The thermal break column is connected to the cylindrical liner through the protective sleeve by self-tapping screws. The beneficial effects of this invention are as follows: 1. This invention employs a thermal break technology to prevent heat transfer and loss between the interior and exterior, saving energy and aligning with national policies promoting energy conservation and environmental protection. The interior and exterior structures are connected by two thermal break strips to form a double thermal break structure, providing excellent thermal insulation. The two thermal break columns of the interior and exterior structures are connected by two parallel thermal break strips. These two strips connect the thermal break columns, allowing for selection of thermal break strips based on actual installation requirements, thus accommodating window frames of various sizes. Simultaneously, the connection of the thermal break columns via the second thermal break strip enhances the thermal insulation performance of the window frame. This solves the problem of fixed window and door profiles in existing technologies, which cannot be modified according to actual shapes.

[0015] 2. The thermal break columns adopt isosceles trapezoidal structural profiles, which facilitates installation and makes it easy to ensure that the connection surfaces of two adjacent thermal break columns are parallel, facilitating the installation of thermal break strip one and thermal break strip two. A transition plate with sealing thermal break strip two is fastened between the two isosceles trapezoidal structural profiles on the indoor side or the two isosceles trapezoidal structural profiles on the outdoor side. The transition plate serves as a cover between the two isosceles trapezoidal structural profiles.

[0016] 3. The right-angle splicing and isosceles trapezoidal structural profiles are interlocked to form a modular structure, which makes it easy to adjust the length of thermal break strip one and thermal break strip two according to actual installation needs, thus forming a modular installation of window frame profiles. The installation method is simple and has a wide range of applications.

[0017] 5. The wide splicing structure connects the two thermal break columns corresponding to the indoor side structure and the two thermal break columns corresponding to the outdoor side structure to form the indoor side frame. The wide splicing structure works in conjunction with the corresponding indoor side structure and the corresponding outdoor side structure to connect the indoor side structure and the outdoor side structure to form a complete window frame structure. The splicing method is simple and has good thermal insulation and heat insulation properties.

[0018] 6. A flat cover plate is installed between the wing panels of the indoor and outdoor structures to protect the thermal insulation strip and form an insulation cavity, providing good thermal insulation performance. Small cover plates are fastened to the wing panels to support them, preventing the T-shaped part on the wing panel from causing the U-shaped part to deform. These cover plates also increase the sealing between the two wing panels and the flat cover plate, further enhancing the thermal insulation performance when the thermally broken column is connected to the wing panel.

[0019] 7. The reinforced liner is located in the middle of the frame structure and can fill the frame structure. The thermal break columns are connected to the reinforced liner with screws, and the four thermal break columns are stably connected to the reinforced liner, which improves the stability of the device.

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

[0024] like Figures 1-8As shown in Embodiment 1, a variable-shape thermal break core structure includes an indoor side structure and an outdoor side structure. Both the indoor and outdoor side structures are equipped with corresponding thermal insulation strips 1. The indoor side structure is connected to the outdoor side structure via the thermal insulation strips 1 to form a frame structure. Both the indoor and outdoor side structures include two symmetrically arranged thermal break columns 3. One side of each thermal break column 3 is connected to a second thermal insulation strip 2, and the two thermal break columns 3 are connected via the second thermal insulation strip 2. The other side of each thermal break column 3 is connected to the thermal insulation strip 1. The frame structure can serve as a thermal break frame or a thermal break fan frame. The indoor and outdoor side structures are connected by the two thermal insulation strips 1 to form a double thermal break frame structure, resulting in good thermal insulation performance. The two thermally broken columns 3 on the indoor side and the two thermally broken columns 3 on the outdoor side are connected by corresponding thermal insulation strips 2. Thermal insulation strips 2 are two parallel strips connecting the thermally broken columns 3. By selecting different thermal insulation strips, the width of the window frame can be adjusted to accommodate more window frame sizes. Simultaneously, the connection of the thermally broken columns 3 via thermal insulation strips 2 enhances the thermal insulation performance of the window frame. The use of thermal break technology blocks heat transfer and loss between the indoor and outdoor spaces, saving energy and aligning with the national policy of energy conservation and environmental protection.

[0025] like Figure 2 and Figure 3 As shown in Embodiment 2, a variable-shape thermal break core structure includes an indoor side structure and an outdoor side structure. Both the indoor and outdoor side structures are equipped with corresponding thermal insulation strips 1. The indoor side structure is connected to the outdoor side structure via the thermal insulation strips 1 to form a frame structure. Both the indoor and outdoor side structures include two symmetrically arranged thermal break columns 3. One side of each thermal break column 3 is connected to a second thermal insulation strip 2, and the two thermal break columns 3 are connected together via the second thermal insulation strip 2. The other side of each thermal break column 3 is connected to the thermal insulation strip 1. The frame structure can serve as a thermal break frame or a thermal break fan frame. The indoor and outdoor side structures are connected by the two thermal insulation strips 1 to form a double thermal break frame structure, resulting in good thermal insulation performance. The two thermally broken columns 3 on the indoor side and the two thermally broken columns 3 on the outdoor side are connected by corresponding thermal insulation strips 2. Thermal insulation strips 2 are two parallel strips connecting the thermally broken columns 3. By selecting different thermal insulation strips, the width of the window frame can be adjusted to accommodate more window frame sizes. Simultaneously, the connection of the thermally broken columns 3 via thermal insulation strips 2 enhances the thermal insulation performance of the window frame. The use of thermal break technology blocks heat transfer and loss between the indoor and outdoor spaces, saving energy and aligning with the national policy of energy conservation and environmental protection.

[0026] In this embodiment, the thermal break column 3 is an isosceles trapezoidal structural profile. This design facilitates installation and ensures that the connecting surfaces of adjacent thermal break columns 3 are parallel, facilitating the installation of the "I"-shaped thermal insulation strips 1 and 2. One side of the isosceles trapezoidal profile has two grooves 3-1 that mate with the thermal insulation strip 2, and the other side has a groove 3-2 that mates with the thermal insulation strip 1. A splice cap is attached to the isosceles trapezoidal profile. Multiple snap-fit ​​flanges are provided on the outer side of the thermal break column 1. These flanges can snap onto, but are not limited to, curved cover plates, wide splices, and right-angle splices, allowing for variable shapes. A transition plate with a sealing and heat insulation strip 2 is fastened between the two isosceles trapezoidal structural profiles of the indoor side structure or the two isosceles trapezoidal structural profiles of the outdoor side structure. The transition plate is used to make the outer end faces of the indoor side structure and the outdoor side structure flush, so as to achieve the aesthetics of the window frame.

[0027] In this embodiment, the cover is an arc-shaped cover 4, with an L-shaped fastener 4-1 on its inner side. The L-shaped fastener 4-1 is fastened to the retaining flange 3-3 at the bottom of the isosceles trapezoidal structural profile. The retaining flange 3-3 is a cross-shaped flange. The transition plate is an arc-shaped cover 4 with the same curvature and structure as the arc-shaped cover 4. The arc-shaped cover 4 is fastened to the cross-shaped flange by the L-shaped fastener 4-1. The three arc-shaped covers 4 arranged in sequence connect the two thermally broken columns on the corresponding indoor side structure to form the indoor side frame, and connect the two thermally broken columns on the corresponding outdoor side structure to form the outdoor side frame, realizing the arc-shaped cover plate cooperation between the fastened arc-shaped cover plate and the two isosceles trapezoidal structural profiles. The outer end face of the arc-shaped cover plate and the outer end face of the cross-shaped flange are located on the same horizontal plane. The use of arc-shaped cover plates on the isosceles trapezoidal structural profile can form corner columns.

[0028] In practical use, the thermal break column 3 and the curved cover 4 are paired together, and combined with the inner and outer turning pipes, they can be used for any angle of rotation. Corresponding curved cover plates are installed on both the indoor and outdoor thermal break columns, and these are installed between two isosceles trapezoidal structural profiles, forming a corner column profile that can adapt to various angles, offering a wide range of applications. External frame columns are installed on both the indoor and outdoor structures. These external frame columns fit onto the curved cover plates and slide along them, allowing for angle adjustments according to installation needs. The thermal break partition technology is energy-saving and environmentally friendly, with independent colors for the inner and outer sides, further expanding its applicability.

[0029] like Figure 2 and Figure 4As shown in Embodiment 3, a variable-shape thermal break core structure differs from the technical solution of Embodiment 2 in that the splice is a right-angle splice 5, with fasteners 5-1 at both ends. The fasteners 5-1 engage with the retaining flange 3-3 located at the bottom of the isosceles trapezoidal structural profile. The retaining flange 3-3 is a cross-shaped flange, and the fastener 5-1 is a retaining groove that engages with the cross-shaped flange, securing the right-angle splice 5 to the thermal break column 3 of the isosceles trapezoidal structural profile. The use of the right-angle splice 5 and the isosceles trapezoidal structural profile to engage forms a modular structure, facilitating the adjustment of the lengths of the thermal break strips 1 and 2 according to actual installation requirements, thus enabling modular installation of the window frame profile. The installation method is simple, and the angle can be changed; the thermal break technology is energy-saving and environmentally friendly; and the independent colors inside and outside the thermal break broaden its application.

[0030] Specifically, the thermal break column 3, paired with the right-angle cap 5, can be used as a reinforced column, connecting doors and windows from four directions while achieving thermal break technology for energy conservation and environmental protection. The right-angle cap 5 is an L-shaped cap, which is fastened to the flange 3-3 of the isosceles trapezoidal structural profile by fasteners 5-1. A cavity is formed between the right-angle cap 5 and the isosceles trapezoidal structural profile, forming two layers of cavities that further improve the thermal insulation and heat preservation of the frame. The two thermal break columns 3 on the indoor and outdoor structures are connected by two thermal break strips 2, ensuring the connection strength of the two thermal break columns 3 while also improving the thermal insulation and heat preservation between them. A transition plate can also be installed between the two isosceles trapezoidal structural profiles on the indoor and outdoor structures. The outer end face of the transition plate is flush with the right-angle cap 5, ensuring the neatness and aesthetics of the outer end faces of the indoor and outdoor structures.

[0031] All other structures are the same as in Example 2.

[0032] like Figure 2 and Figure 5 As shown in Embodiment 4, a variable-shape thermal break core structure differs from the technical solution of Embodiment 2 in that the cover is a wide cover 6, with two interlocking grooves 6-1 inside. The two interlocking grooves 6-1 respectively interlock with the corresponding thermal break columns 3. The thermal break columns 3 are isosceles trapezoidal profiles, and the interlocking grooves 6-1 interlock with the retaining flanges 3-3 of the isosceles trapezoidal profiles. The retaining flanges 3-3 are cross-shaped flanges. The wide cover 6 cooperates with the corresponding indoor and outdoor structures, connecting the indoor and outdoor structures to form a complete window frame structure. The splicing method is simple, and the thermal insulation and heat insulation properties are good.

[0033] Specifically, the thermal break column combined with the wide splice canopy can be used as a straight-joint reinforced column. Determine the width of the wide splice canopy 6, select the length of the thermal insulation strip 2 based on the width of the wide splice canopy 6, and then splice the thermal break column 3, the thermal insulation strip 2, and the wide splice canopy 6 to form the indoor side structure and the outdoor side structure. Then connect the outdoor side structure and the indoor side structure through the thermal insulation strip 1 to form a straight-joint reinforced column.

[0034] All other structures are the same as in Example 2.

[0035] like Figure 2 and Figure 5 As shown in Embodiment 5, a variable-shape thermal break core structure differs from the technical solution of Embodiment 3 in that the splicing cover includes wing panels 7, with small cover plates 7-1 fastened to the wing panels 7. A flat cover plate 11 is provided between two adjacent wing panels 7, located between the two wing panels 7 of the indoor and outdoor structures. The flat cover plate 11 is fastened to the thermal break column, increasing the stability of the connection between the thermal break column and the flat cover plate. The wing panels 7 include T-shaped and U-shaped sections, which are integrally formed. The small cover plate 7-1 is fastened to the U-shaped section. An insulation board is provided between the wing panels connected to the two thermal break columns of the indoor and outdoor structures. The insulation board is confined between the two T-shaped sections, further limiting the insulation performance of the indoor and outdoor structures.

[0036] Specifically, the thermal break column 3, along with the wing panels, flat cover plate, and small cover plate, is used as an insulation module, paired with insulation boards. The thermal break column is connected to the thermal break strip 1 and thermal break strip 2 to form a frame structure. Wing panels 7 are installed on the thermal break column of the indoor structure. The two ends of the wing panels 7 are engaged with the "+" shaped flanges of the thermal break column. Corresponding insulation boards are provided between the two wing panels 7 of the indoor structure and between the two wing panels 7 of the outdoor structure, increasing the insulation performance of the device. A flat cover plate 11 is provided between the wing panels 7 of the indoor structure and the wing panels 7 of the outdoor structure to protect the thermal break strip and form an insulation cavity, providing good insulation performance. A small cover plate 7-1 is fastened to the wing panel 7. The small cover plate 7-1 is used to support the wing panel 7, prevent the T-shaped part on the wing panel 7 from causing the U-shaped part to deform, and also increase the sealing between the two wing panels 7 and the flat cover plate 11, further increasing the thermal insulation performance when the thermal break column is connected to the wing panel 7.

[0037] All other structures are the same as in Example 2. like Figure 2 and Figure 6As shown in Embodiment 6, a variable-shape thermal break core structure differs from the technical solution of Embodiment 4 in that the thermal break column 3 on the outdoor structure includes a frame-type column profile 9. A glass clip 12 is connected to the frame-type column profile 9 by screws. The glass clip 12 and the frame-type column profile 9 form a separate glass clip, allowing for relatively independent and unaffected glass installation and replacement. A wide cover plate 10 with a U-shaped structure is provided between two adjacent glass clips 12. The thermal break column 3 on the indoor structure includes a frame-type column profile 8. A flat cover plate 11 is provided between two frame-type column profiles 8. Corresponding glass strips are provided on both the frame-type column profile 9 and the frame-type column profile 8. Glass, which is insulated glass, is placed between the two glass strips.

[0038] Specifically, the thermal break column 3, in conjunction with the wide cover plate 10, the flat cover plate 11, and the glass clamp 12, serves as a curtain wall column, capable of assembling insulated glass. It can also accommodate glass of different thicknesses by altering the length of the thermal break strip 1. The separate glass clamp allows for relatively independent glass installation and replacement without interference. The frame-type column profile 9 is connected to the interior side frame profile via two thermal break strips 2 and the flat cover plate 11. The frame-type column profile 8 is connected to the exterior side frame via thermal break strip 2 and the wide cover plate 10. Glass is installed between the interior and exterior side frames. Both the glass retaining strip and the frame-type column profile 8 have grooves for fastening the glass retaining strip. The insulated glass is located between the glass retaining strips. Glass sealant is filled between the wide cover plate 10 and the insulated glass for auxiliary sealing, increasing the sealing performance between the exterior side frame and the glass, and also increasing the thermal insulation and heat insulation properties of the exterior side frame.

[0039] All other structures are the same as in Example 1.

[0040] like Figure 2 and Figure 7 As shown in Embodiment 7, a variable-shape thermal break core structure differs from the technical solution of Embodiment 4 in that the thermal break column 3 includes a frame-shaped column profile 13. Wing plates 14 are provided on both adjacent sides of the frame-shaped column profile 13, and a right-angle cover plate 15 is provided between the two wing plates 14. The wing plates 14 are T-shaped plates, and the wing plates 14 and the frame-shaped column profile 13 are integrally formed. Insulating set screws 16 are provided on the wing plates 14, and the insulating set screws 16 are arranged parallel to the thermal insulation strip 1. A U-shaped groove is provided between the T-shaped plate and the frame-shaped column profile 13, and the insulating set screws 16 are installed in the U-shaped groove, which can be applied to scenarios requiring insulation.

[0041] All other structures are the same as in Example 6.

[0042] like Figure 2 and Figure 8As shown in Embodiment 8, a variable-shape thermal break core structure differs from the technical solution of Embodiment 4 in that a reinforcing liner is installed inside the frame structure. The reinforcing liner is located in the middle of the frame structure. When the thermal break column 3 is made of an isosceles trapezoidal profile, the upper base of the isosceles trapezoidal profile fits onto the reinforcing liner. The lower base of the isosceles trapezoidal profile has a positioning groove for positioning connecting screws. The connecting screws are driven vertically into the lower base of the isosceles trapezoidal profile, pass through the upper base of the isosceles trapezoidal profile, and are then fixed to the reinforcing liner. The reinforcing liner can fill the frame structure. The thermal break columns 3 are connected to the reinforcing liner by connecting screws, further stably connecting the four thermal break columns 3 to the reinforcing liner and connecting the four thermal break columns 3 and the reinforcing liner into a whole, improving the stability of the device.

[0043] In this embodiment, the reinforcing liner is a cylindrical liner 17, and a sheath 18 is fitted on the outer wall of the cylindrical liner 17. The thermal break column 3 is connected to the cylindrical liner 17 by self-tapping screws passing through the sheath 18. The sheath 18 is an elastic sheath, which includes an inner ring and an outer ring. Four mounting cavities are formed between the inner and outer rings. The thermal break column is pressed against the sheath. The cylindrical liner provides support while also achieving a certain thermal insulation function. A reinforcing liner can be added inside the thermal break column 1. The reinforcing liner can be adjusted to different wall thicknesses to meet higher strength requirements. The thermal break column 1 and the reinforcing liner 3 are connected by self-tapping screws. The outer ring of the reinforcing liner is made of PVC material, which serves to position the reinforcing liner and does not change the thermal break barrier process of the thermal break column.

[0044] All other structures are the same as in Example 7.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
