Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to an energy-saving curtain wall window frame and curtain wall system. Background Technology

[0002] Glass curtain walls are a common building facade enclosure or decorative structure. To meet thermal insulation requirements, the glass panels in glass curtain walls are often designed as double-layer or multi-layer structures, and some products have hollow layers inside the glass panels. By filling the hollow layer with argon gas or drawing a vacuum, the glass panels can achieve good thermal insulation. However, the frames used to connect and fix the glass panels in glass curtain walls are usually made of metal. Metal has a high thermal conductivity, which makes it easy for thermal bridges to form at the joints of the glass curtain walls, which is not conducive to thermal insulation and energy saving.

[0003] To address the aforementioned issues, existing technologies typically employ aluminum alloy thermal break systems, using rigid plastic to connect the broken aluminum alloy sections. This leverages the fact that plastic has significantly lower thermal conductivity than metal to reduce the overall heat transfer coefficient at the glass curtain wall joints. However, when energy-saving requirements are high, aluminum alloy thermal break systems may still struggle to meet insulation needs. Further insulation measures, such as increasing the number of glass layers or adding warm edge insulation films, are necessary. This results in glass curtain walls failing to simultaneously meet insulation requirements while also achieving lightweight and cost-effectiveness. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that the thermal insulation effect of aluminum alloy thermal break systems in the background technology is difficult to meet the high energy-saving requirements, and other measures can be used to further insulate the thermal insulation, which makes it impossible for curtain wall systems to achieve both lightweight and economical performance while meeting the thermal insulation requirements.

[0042] Example 1

[0043] like Figures 1 to 5 As shown, this embodiment provides an energy-saving curtain wall window frame, including a keel 1, an energy-saving sub-frame 2, glass panels 4, and a pressure plate 3; wherein: two glass panels 4 are distributed on both sides of the energy-saving sub-frame 2, one end of the energy-saving sub-frame 2 is connected to the keel 1, and the other end is connected to the pressure plate 3, and the pressure plate 3 extends laterally out of the side of the energy-saving sub-frame 2 to press the glass panels 4 onto the keel 1, thereby connecting and fixing the glass panels 4 to form a curtain wall system.

[0044] Keel 1 is a structural component in the curtain wall system that supports and fixes the glass panels 4. It includes vertical keels and horizontal keels. In some cases, the vertical keels are called columns and the horizontal keels are called keels. Keel 1 can be made of metal profiles, such as aluminum alloy, steel, etc. Figure 1 A cross-sectional view of the keel 1 is shown. It can be understood that the keel 1, the energy-saving sub-frame 2, and the pressure plate 3 can all extend upward in a third direction. In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0045] The energy-saving subframe 2 is a glass fiber reinforced composite component made of glass fiber reinforced composite material. Glass fiber reinforced composite material refers to a material that uses glass fiber and its products as reinforcing and matrix materials, and is compounded through a certain molding process. It is mainly used in the aerospace field and is a known material. In this embodiment, the energy-saving subframe 2 is made of high-performance polyurethane composite material. High-performance polyurethane composite material is a type of glass fiber reinforced composite material. It uses polyurethane (PU) as the matrix and significantly improves its mechanical properties and heat resistance by adding reinforcing materials (such as fibers, nanofillers, etc.) or optimizing the molecular structure design.

[0046] Preferably, the energy-saving subframe 2 is made of glass fiber reinforced composite material with a thermal conductivity of 0.33W / m·K-0.36W / m·K.

[0047] The glass panel 4 can be a single layer, double layer or multi-layer glass. Two glass panels 4 can be set end to end opposite each other, and there is a gap between the ends of the two glass panels 4. The energy-saving sub-frame 2 is located in the gap. The energy-saving sub-frame 2 serves to connect the keel 1 and the pressure plate 3 located on both sides of the glass panel 4. The pressure plate 3 can be a metal component, such as an aluminum alloy component or a stainless steel component.

[0048] The energy-saving curtain wall window frame described in this embodiment has an energy-saving sub-frame 2 made of glass fiber reinforced composite material between the ends of the two glass panels 4. By utilizing the low thermal conductivity of glass fiber reinforced composite material, the thermal bridge effect at the connection of the curtain wall system can be greatly reduced. The unit heat transfer coefficient can be reduced without increasing the system glass configuration, which has good economy and practicality.

[0049] Taking a specific working condition as an example: by using an energy-saving sub-frame 2 made of glass fiber reinforced composite material to connect the keel 1 and the pressure plate 3, the heat transfer path is extended. Under the same glass configuration, the heat transfer coefficient is reduced by approximately 0.2 W / m compared to aluminum alloy doors and windows. 2 •k. Reducing the unit heat transfer coefficient without increasing the system glass configuration offers good economic efficiency and practicality; moreover, the energy-saving sub-frame 2 described in this embodiment has better fire resistance integrity than PVC windows, and its mechanical properties are far superior to traditional window profiles, such as aluminum alloy thermal break windows, PVC windows, and wooden frame windows, thus having a wider range of applications in the context of generally improved energy-saving standards.

[0050] The energy-saving sub-frame 2 is defined with its two ends in the first direction as the first end and the second end, respectively. In some embodiments, such as Figure 1 As shown, the first end of the energy-saving sub-frame 2 is connected to the keel 1 by a snap-fit, and the second end of the energy-saving sub-frame 2 is fastened to the pressure plate 3 by bolts.

[0051] In order for the pressure plate 3 to securely press the glass panel 4, the connection between the energy-saving sub-frame 2 and the keel 1 needs to be able to withstand a large force along the first direction. For this purpose, it is preferable to provide a protrusion 21 protruding along the second direction on the first end of the energy-saving sub-frame 2, and to provide a locking groove 11 with a groove depth parallel to the second direction on the keel 1. The protrusion 21 extends at least partially into the locking groove 11, so that the two are locked together. Thus, the force along the first direction is applied to the protrusion 21 through the groove wall of the locking groove 11 to prevent the energy-saving sub-frame 2 from moving away from the keel 1, so that the pressure plate 3 can securely press the glass panel 4 onto the keel 1.

[0052] Preferably, the keel 1 is provided with at least two first positioning holes 12 spaced apart along the second direction, and the energy-saving sub-frame 2 is provided with at least two second positioning holes 28 spaced apart along the second direction. The first positioning holes 12 and the second positioning holes 28 are provided correspondingly, and the positioning bolts 29 pass through the first positioning holes 12 and the second positioning holes 28.

[0053] It is understood that the positioning bolt 29 described in this embodiment serves a positioning function rather than a primary load-bearing function. The fixing of the energy-saving sub-frame 2 and the keel 1 mainly relies on the snap-fit ​​connection. The snap-fit ​​connection can reduce the number of screws used, reduce damage to the energy-saving sub-frame 2 and the keel 1, reduce construction errors during manual tightening, and improve the integrity of the energy-saving sub-frame 2 and the keel 1, thereby improving the heat insulation effect. Moreover, since both the keel 1 and the energy-saving sub-frame 2 extend along a third direction, the force on the snap-fit ​​connection between the energy-saving sub-frame 2 and the keel 1 is continuous, resulting in a better force transmission path and higher reliability.

[0054] Preferably, the projection of the glass panel 4 in the second direction is located within the projection range of the energy-saving sub-frame 2 in the second direction; that is, the first end and the second end of the energy-saving sub-frame 2 both extend out of the two opposite surfaces of the glass panel 4, so that there is a larger gap between the pressure plate 3 and the keel 1, thereby improving the heat insulation effect.

[0055] Preferably, the projection of the end of the glass panel 4 in the first direction is located within the projection range of the keel 1 in the first direction, so that the pressure plate 3 can press the glass panel 4 onto the keel 1.

[0056] In some embodiments, the energy-saving sub-frame 2 is provided with a first connecting plate 22 and a second connecting plate 23 near the second end. The first connecting plate 22 and the second connecting plate 23 are spaced apart along a first direction. The pressure plate 3 is located on the side of the first connecting plate 22 away from the second connecting plate 23. The fixing bolts 25 pass through the pressure plate 3, the first connecting plate 22 and the second connecting plate 23 in sequence to achieve a tight connection between the pressure plate 3 and the energy-saving sub-frame 2.

[0057] The first connecting plate 22 and the second connecting plate 23, which are spaced apart, can improve the connection strength between the fixing bolt 25 and the energy-saving sub-frame 2. Furthermore, a liner 24 is provided between the first connecting plate 22 and the second connecting plate 23. The fixing bolt 25 passes through the pressure plate 3, the first connecting plate 22, the liner 24 and the second connecting plate 23 in sequence. The liner 24 can be a metal component, such as a copper sheet, an iron sheet, an alloy sheet, etc. By providing the liner 24, the holding force of the energy-saving sub-frame 2 can be improved, the connection strength can be increased, and the tightness between the fixing bolt 25 and the energy-saving sub-frame 2 can be improved, which helps to reduce the shaking between the pressure plate 3 and the energy-saving sub-frame 2.

[0058] It is understood that the outer circumferential surface of the fixing bolt 25 may be threaded, and the end of the fixing bolt 25 may be a pointed tip. The fixing bolt 25 can be tightened to allow the bushing 24 to pass through it, thereby improving the connection tightness between the fixing bolt 25 and the bushing 24. This ensures a tight connection between the bushing 24 and the energy-saving sub-frame 2, thus improving the connection tightness between the fixing bolt 25 and the energy-saving sub-frame 2. The bushing 24 and the energy-saving sub-frame 2 can be connected by snap-fit ​​or compression.

[0059] In some embodiments, a subframe 5 is provided between the glass panel 4 and the keel 1. The subframe 5 can be a metal component, such as an aluminum alloy or stainless steel component. The subframe 5 can fill the gap between the glass panel 4 and the keel 1, so that the pressure plate 3 can fasten the glass panel 4. It can also protect the energy-saving subframe 2.

[0060] Preferably, the subframe 5 includes a first plate and a second plate that are parallel to each other, and a side plate that connects the first plate and the second plate; the first plate of the subframe 5 is connected to the keel 1, the second plate is connected to the glass panel 4, the outer surface of the side plate is flush with the side of the keel 1, and the side plate protrudes from the surface of the second plate so that a semi-enclosed cavity is formed between the subframe 5 and the glass panel 4.

[0061] Furthermore, a first sealing strip 51 is provided between the subframe 5 and the keel 1, and a second sealing strip 52 is provided between the subframe 5 and the glass panel 4. Both the first sealing strip 51 and the second sealing strip 52 are squeezed and fixed to improve the fixing and sealing effects. Both the first sealing strip 51 and the second sealing strip 52 can be made of rubber material with low thermal conductivity to reduce the overall heat transfer coefficient. The second sealing strip 52 can be located in the above-mentioned semi-enclosed cavity.

[0062] like Figure 3 As shown, a first slot can be provided on the keel 1. The opening width of the first slot is smaller than the width of its internal cavity. A first snap-fit ​​member can be provided on the first sealing strip 51. The end of the first snap-fit ​​member can protrude to both sides so that the first sealing strip 51 can be snapped and fixed on the first slot, thereby improving the installation accuracy and reducing the installation difficulty.

[0063] Preferably, a third sealing strip 41 is provided between the pressure plate 3 and the glass panel 4; a second slot may be provided on the pressure plate 3, the opening width of the second slot is smaller than the width of its internal cavity, a second snap-fit ​​member may be provided on the third sealing strip 41, the end of the second snap-fit ​​member may protrude to both sides, and the third sealing strip 41 is snap-fitted with the pressure plate 3 to improve the installation accuracy and reduce the installation difficulty.

[0064] Preferably, a foam rod 43 is provided between the energy-saving sub-frame 2 and the glass panel 4. The foam rod 43 can be located between the end of the glass panel 4 and the side of the energy-saving sub-frame 2, with two foam rods 43 distributed on both sides of the energy-saving sub-frame 2.

[0065] Both the third sealing strip 41 and the foam rod 43 can be made of rubber with low thermal conductivity. Both the third sealing strip 41 and the foam rod 43 are squeezed and fixed to improve the fixing and sealing effect.

[0066] Furthermore, the third sealing strip 41 is provided with a protrusion 42, which extends to the side of the energy-saving sub-frame 2. During installation, the end of the protrusion 42 can be bent and overlapped on the side of the energy-saving sub-frame 2, and the restoring force of the protrusion 42 can be used to make the protrusion 42 tightly connected to the energy-saving sub-frame 2.

[0067] Preferably, the pressure plate 3 has a limiting protrusion on the surface near the energy-saving sub-frame 2, and the two sets of limiting protrusions are spaced apart along the second direction. The second end of the energy-saving sub-frame 2 is located between the two sets of limiting protrusions. Each set of limiting protrusions includes a rib that runs along the third direction or multiple ribs that are spaced apart along the third direction.

[0068] Preferably, a cover 31 is provided on the side of the pressure plate 3 away from the energy-saving sub-frame 2. The two sides of the cover 31 can be snapped together with the energy-saving sub-frame 2. The cover 31 can protect the pressure plate 3 and the fixing bolts 25, and can make the curtain wall more beautiful.

[0069] Furthermore, such as Figure 4 As shown, a sealing element 44 is provided on the outer side of the third sealing strip 41. The sealing element 44 is located between the cover 31, the pressure plate 3 and the glass panel 4. The sealing element 44 can further improve the sealing effect of the curtain wall structure. The sealing element 44 can be a sealant or the like.

[0072] Preferably, the glass panel 4 is a double-glazed insulated glass, and the glass panel 4 is filled with argon gas; a connecting frame is provided between the two layers of glass, and the outside of the connecting frame is provided with sealant.

[0073] Specifically, the glass panel 4 can be tempered Low-E insulated argon-filled glass; for example, model number: 6Low-E+12Ar+6.

[0074] Example 2

[0075] This embodiment provides an energy-saving curtain wall window frame. Based on embodiment 1, the energy-saving sub-frame 2 includes a base plate 26, side plates 27 and a connecting plate. At least two side plates 27 are connected to the same side of the base plate 26, and the connecting plate is connected to the side plates 27 and spaced apart from the base plate 26.

[0076] Preferably, both ends of the base plate 26 protrude beyond the surface of the outermost side plate 27, so as to Figure 1 For example: Figure 1The base plate 26 includes two side plates 27 spaced apart on the left and right sides. For the left end of the base plate 26, the left end of the base plate 26 extends beyond the leftmost side plate 27. For the right end of the base plate 26, the right end of the base plate 26 extends beyond the rightmost side plate 27. The portion of the base plate 26 extending beyond the outermost side plate 27 can serve as the protrusion 21 described in Embodiment 1. The keel 1 is provided with two corresponding snap-fit ​​grooves 11 with a depth parallel to the second direction. One end of the base plate 26 is located in one of the snap-fit ​​grooves 11, and the other end of the base plate 26 is located in the other snap-fit ​​groove 11, so that the base plate 26 can be snap-fitted and connected to the keel 1.

[0077] like Figure 1 As shown, the keel 1 can be a hollow rectangular profile. An L-shaped protrusion can be provided on the side of the keel 1 connected to the energy-saving sub-frame 2. The L-shaped protrusion and the side of the keel 1 enclose to form a snap-fit ​​groove 11. The base plate 26 and the snap-fit ​​groove 11 both extend in the third direction, so that the base plate 26 and the snap-fit ​​groove 11 can form a continuous force-bearing structure, making the force transmission path between the keel 1 and the energy-saving sub-frame 2 better and more reliable. Moreover, the snap-fit ​​can reduce the number of openings on the energy-saving sub-frame 2 and the keel 1, which is conducive to improving the integrity of both and thus improving the heat insulation effect.

[0078] For ease of description, this embodiment is referred to as Figure 1 The left and right sides of the middle base plate 26 are the left end and the right end. In the actual structure, the left end and the right end are not limited to a spatial left-right relationship, but can also be a vertical relationship, etc.

[0079] Preferably, the connecting plate includes a first connecting plate 22 and a second connecting plate 23 spaced apart along a first direction. The first connecting plate 22, the second connecting plate 23 and two side plates 27 enclose a rectangular cavity 210. A liner 24 is provided inside the rectangular cavity 210.

[0080] Furthermore, the liner 24 is a hollow rectangular tube with a rectangular ring-shaped cross-section. The outer wall of the liner 24 is pressed against the inner wall of the rectangular cavity 210 to improve the tightness of the connection between the liner 24 and the energy-saving sub-frame 2.

[0081] Preferably, the base plate 26, the side plate 27 and the connecting plate are integrally formed; the side plate 27 is perpendicular to the base plate 26, and the first connecting plate 22 and the second connecting plate 23 are both perpendicular to the side plate 27.

[0082] In some embodiments, the keel 1 is provided with a first positioning hole 12, and the part of the bottom plate 26 extending out of the side plate 27 is provided with a second positioning hole 28. The first positioning hole 12 and the second positioning hole 28 correspond to each other. The positioning bolt 29 passes through the first positioning hole 12 and the second positioning hole 28. The positioning bolt 29 plays a positioning role rather than a main load-bearing role.
