Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a segmented double-layer curtain wall system. Background Technology

[0002] Large-span curtain walls have been widely used in various fields, such as large exhibition buildings, transportation buildings, cultural buildings, and sports buildings. As an important feature of modern architecture, they not only bear the function of structural safety but also combine aesthetics and practicality. Traditional double-layer curtain walls typically have horizontal panel spacing of around 1500mm. When the horizontal panel spacing is larger, vertical keels are installed in the middle of the top and bottom horizontal beams for support. These keels, composed of steel or aluminum structures, bear the load and are suitable for buildings with high floor-to-floor spacing. The keels are generally composed of single, large steel or aluminum profiles forming simply supported beams for load transfer, but this can affect the overall transparency of the double-layer curtain wall panels.

[0003] Glass ribs, as an important component of modern building curtain walls, possess multiple functional characteristics such as support, aesthetics, light transmission, and weather resistance. However, glass has poor toughness, and the connection of glass ribs must avoid hard contact that could cause stress concentration. Therefore, there is an urgent need for a segmented double-layer curtain wall system to solve the problem of ensuring both structural safety and transparency in large-segment double-layer curtain walls.

[0049] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0050] like Figures 1-9 As shown, an embodiment of this utility model proposes a segmented double-layer curtain wall system, comprising:

[0051] The top beam 1, the first column 2, the bottom beam 3 and the second column 4 are connected end to end by self-tapping screws to form a frame structure. The frame structure is connected to the glass panel 5 and the glass door 6 to form a cavity structure.

[0052] The glass rib 7 is located within the cavity structure and is connected between the top crossbeam 1 and the bottom crossbeam 3.

[0053] In this embodiment, when the horizontal division is large, the vertical deformation of the beam will exceed the limit due to the large horizontal span. By connecting the glass rib 7 between the top beam 1 and the bottom beam 3 as a support, the overall strength can be improved, the deformation of the top beam 1 and the bottom beam 3 can be avoided, and the overall transparency can be guaranteed by utilizing the good light transmittance of the glass material.

[0054] In this embodiment, the glass panel 5 is divided into two pieces of glass along the span of the crossbeam. The glass panel 5 is fixed by adhesive bonding. The edges of the two pieces of glass that are far apart are respectively bonded to the first column 2 and the second column 4 by adhesive bonding, while the edges of the two pieces of glass that are close together are bonded to the glass ribs 7 by adhesive bonding. The bottom edges of the two pieces of glass are bonded to the bottom crossbeam 3, and the top edges are bonded to the top crossbeam 1, thereby ensuring the integrity of the entire double-layer curtain wall panel. The first column 2 and the second column 4 are interlocked, and the top crossbeam 1 and the bottom crossbeam 3 are interlocked, which facilitates the disassembly and installation between the segmented double-layer curtain wall panels.

[0055] The glass panel 5 is bonded to the frame structure near the outdoor end by structural adhesive, and the glass door 6 is connected to the frame structure near the indoor end by hinge 61.

[0056] The glass rib 7 is perpendicular to the top crossbeam 1, the bottom crossbeam 3, and the glass panel 5, and is positioned on the centerline of the bottom crossbeam 3. The centerline position ensures that the load is evenly distributed on both sides of the bottom crossbeam 3, extending its service life. The top of the glass rib 7 is fixedly connected to the top crossbeam 1 via a hanging lug connector 8, and the bottom of the glass rib 7 is fixedly connected to the bottom crossbeam 3 via a first bolt 73. The front side of the glass rib 7 is fixedly connected to the glass panel 5 via structural adhesive. The glass rib 7 is fixedly connected on three sides, and a certain space is left between the rear side and the glass door 6. The glass rib 7 and the glass panel 5 form a T-shaped support, which enhances the stability of the overall structure and ensures the normal opening of the glass door 6.

[0057] This utility model solves the problem of ensuring both safety and transparency in large-division double-layer curtain walls by using glass ribs 7 installed within the cavity structure and connecting the top beam 1 and the bottom beam 3.

[0058] like Figure 2 and Figure 4 As shown, in an optional embodiment of the present invention, it further includes:

[0059] A protective cap 71 fitted on the top of the glass rib 7 and a protective boot 72 fitted on the bottom of the glass rib 7;

[0060] The protective cap 71 is fixedly connected to the top beam 1 via the ear connector 8;

[0061] The protective boot 72 is fixedly connected to the bottom crossbeam 3 by the first bolt 73.

[0062] In this embodiment, glass has poor toughness, and the glass rib connection needs to avoid hard contact to prevent stress concentration. Therefore, it is necessary to design a protective cap 71 fitted on the top of the glass rib 7 and a protective boot 72 fitted on the bottom of the glass rib 7 to avoid hard contact and increase the bearing area to share the load, so as to further solve the problem of ensuring safety and transparency of the double-layer curtain wall with large segment size.

[0063] In an optional embodiment of this utility model, the protective cap 71 includes:

[0064] The first front end plate 712, the first side plate 713, the first rear end plate 714, and the second side plate 715 are connected end to end to form a first hollow cylindrical structure;

[0065] The top plate 711 is connected to the upper end of the first hollow cylindrical structure.

[0066] In this embodiment, the first front end plate 712, the first side plate 713, the first rear end plate 714, the second side plate 715 and the top plate 711 form a space to accommodate the glass rib 7, which makes it easy to put the protective cap 71 on the top of the glass rib 7, and then fix it to the top crossbeam 1 through the ear connector 8, thus ensuring the stability of the glass rib 7.

[0067] In this embodiment, the first front end plate 712 and the glass panel 5 are connected by a first stop 77 through structural adhesive; the second front end plate 722 and the glass panel 5 are connected by a second stop 78 through structural adhesive. The first stop 77 and the second stop 78 are set close to the glass panel 5, which can effectively offset part of the lateral load, thereby reducing the overall stress on the system.

[0068] like Figure 4 As shown, in an optional embodiment of the present invention, the height of the first front end plate 712 is less than the height of the first rear end plate 714.

[0069] In this embodiment, the first front end plate 712 is close to the glass panel 5. When exposed to natural outdoor light, the height of the first front end plate 712 is less than the height of the first rear end plate 714, which can make the lighting effect more sufficient and improve the overall transparency.

[0070] like Figure 4 and Figure 5 As shown, in an optional embodiment of this utility model, the ear-mounted connector 8 includes:

[0071] A connecting base plate 81 is connected to the bottom surface of the top crossbeam 1 by a third bolt 75;

[0072] A first connecting rib 82 and a second connecting rib 83 are connected to the bottom surface of the connecting base plate 81, forming a space between the first connecting rib 82 and the second connecting rib 83 to accommodate the protective cap 71; a connecting threaded hole 821 is provided through the first connecting rib 82, a connecting through hole 831 is provided through the second connecting rib 83, a positioning through hole 716 is provided through the first side plate 713 and the second side plate 715, and a first circular hole 791 is provided through the upper part of the glass rib 7; the connecting threaded hole 821, the positioning through hole 716, the first circular hole 791 and the connecting through hole 831 are coaxially arranged; wherein, a nylon ring is provided inside the first circular hole 791, and glue is injected between the nylon ring and the inner wall of the first circular hole 791;

[0073] The second bolt 74 has its threaded portion passing through the connecting through hole 831, the positioning through hole 716, and the first round hole 791 in sequence, and the threaded portion of the second bolt 74 is threadedly connected to the connecting threaded hole 821.

[0074] The ear hook engagement part 84 is connected to the first connecting rib plate 82 and the second connecting rib plate 83, and the ear hook engagement part 84 forms a π-shaped structure with the first connecting rib plate 82 and the second connecting rib plate 83. The ear hook engagement part 84 is engaged with the base bracket 9.

[0075] In this embodiment, the first connecting rib 82, the second connecting rib 83, the protective cap 71 and the glass rib 7 are fixedly connected by the second bolt 74, the connecting through hole 831, the positioning through hole 716, the first round hole 791 and the connecting threaded hole 821. The bottom plate 81 and the top crossbeam 1 are connected by the third bolt 75, so as to achieve a fixed connection between the upper part of the glass rib 7 and the top crossbeam 1, and ensure the stability of the glass rib 7.

[0076] The first connecting rib 82 and the second connecting rib 83 are connected to the bottom surface of the connecting base plate 81. A space is formed between the first connecting rib 82 and the second connecting rib 83 to accommodate the protective cap 71. The protective cap 71 is protected and isolated from both sides. The symmetrical design also achieves uniform stress distribution, further solving the problem of ensuring safety and transparency while maintaining the double-layer curtain wall with large panel size.

[0077] The engagement between the lug clip 84 and the platform bracket 9 effectively resists horizontal loads and prevents excessive deformation of the top beam 1 and bottom beam 3.

[0078] like Figure 4 and Figure 5 As shown, in an optional embodiment of the present invention, the platform bracket 9 includes:

[0079] 93. A grooved embedded part pre-embedded inside the concrete retaining edge;

[0080] Connection code 97, which is connected to the grooved embedded part 93 by T-bolt 92 and nut;

[0081] The connector 97 has a snap-fit ​​groove 91 formed at its end, and the hook-fit part 84 engages with the snap-fit ​​groove 91.

[0082] In this embodiment, the connecting code 97 and the grooved embedded part 93 are connected by T-bolts 92 and nuts. The snap-fit ​​of the snap-fit ​​groove 91 and the snap-fit ​​part 84 can effectively resist horizontal loads and avoid excessive deformation of the top beam 1 and the bottom beam 3.

[0083] like Figure 5 and Figure 7 As shown, in an optional embodiment of the present invention, the platform bracket 9 further includes:

[0084] Two limiting holes 95 are formed on the surface of the connecting code 97, and are respectively located on both sides of the snap-fit ​​groove 91.

[0085] A limiting bolt 94, the threaded portion of which penetrates the limiting hole 95;

[0086] The limiting block 96 is threadedly connected to the threaded portion of the two limiting bolts 94, and the limiting block 96 abuts against the bottom surface of the lug engaging portion 84.

[0087] In this embodiment, the limiting block 96 is fixed by the limiting hole 95 and the limiting bolt 94. The limiting block 96 limits the bottom surface of the ear latching part 84, which can bear the vertical load and effectively prevent the top beam 1 and bottom beam 3 from deforming excessively. At the same time, the glass rib 7 has a multi-directional limiting function to prevent loosening and the generation of extra directional force, and to more effectively distribute the load.

[0088] like Figure 4 and Figure 6 As shown, in an optional embodiment of the present invention, the protective boot 72 includes:

[0089] The second front end plate 722, the third side plate 723, the second rear end plate 724 and the fourth side plate 725 are connected end to end to form a second hollow cylindrical structure;

[0090] The bottom plate 721 is connected to the lower end of the second hollow cylindrical structure, and the bottom plate 721 is connected to the bottom crossbeam 3 by the first bolt 73;

[0091] The third side plate 723 and the fourth side plate 725 are respectively provided with connecting holes 726, and the bottom of the glass rib 7 is provided with a second round hole 792.

[0092] The pig snout pin 76 passes through the connecting hole 726 and the second round hole 792 in sequence to connect the protective boot 72 and the glass rib 7.

[0093] In this embodiment, a space for accommodating the glass rib 7 is formed by the second front end plate 722, the third side plate 723, the second rear end plate 724, the fourth side plate 725, and the bottom plate 721; the protective boot 72 is fixedly connected to the glass rib 7 by the pig nose pin 76, the connecting hole 726, and the second round hole 792; thus, the glass rib 7 is connected to the bottom crossbeam 3 by the protective boot 72; wherein, a nylon ring is provided inside the second round hole 792, and glue is injected between the nylon ring and the inner wall of the second round hole 792.

[0094] In an optional embodiment of the present invention, the height of the second front end plate 722 is equal to the height of the second rear end plate 724.

[0095] In this embodiment, unlike the protective cap 71, the protective boot 72 is connected to the bottom crossbeam 3. The height difference between the second front end plate 722 and the second rear end plate 724 will not affect the overall permeability of the system. Therefore, the height of the second front end plate 722 is equal to the height of the second rear end plate 724 to further improve the load-bearing capacity.

[0096] In an optional embodiment of this utility model, it further includes:

[0097] Profile frame 102 is connected to the bottom surface of top beam 1 by fifth bolt 101, and venetian blind 103 is fixedly connected to the lower end of profile frame 102.

[0098] In this embodiment, the venetian blind 103 is installed through the profile frame 102 to achieve the light-blocking effect;

[0099] The double-layer curtain wall consists of two layers of glass, inner and outer, formed by glass panels 5 and glass doors 6, with a cavity between them. The depth of this cavity can range from tens of centimeters to several meters, depending on design requirements and the climate conditions of the building's location. The cavity facilitates later maintenance and cleaning, and its structure effectively insulates against external temperatures, providing a relatively stable temperature environment inside the building. Through a reasonable cavity design, the double-layer curtain wall can significantly reduce the impact of external wind and noise on the indoor environment, improving the building's sound insulation performance. With a well-designed air inlet and outlet and ventilation system, the double-layer curtain wall can achieve natural ventilation inside the building, creating a more comfortable and healthy environment for users. The lower end of the profile frame 102 can also be replaced with other components according to actual needs, offering high flexibility and practicality.

[0100] The segmented double-layer curtain wall system provided by this utility model, by setting glass ribs 7 between the top horizontal beam 1 and the bottom horizontal beam 3, connecting the glass ribs 7 to the top horizontal beam 1 through protective caps 71 and hanging ear connectors 8, and connecting the glass ribs 7 to the bottom horizontal beam 3 through protective boots 72, can provide support for the top horizontal beam 1 and the bottom horizontal beam 3, preventing deformation of the top horizontal beam 1 and the bottom horizontal beam 3; at the same time, through the cooperation of the hanging ear connectors 8 and the platform brackets 9, it can effectively resist vertical and horizontal loads, preventing excessive deformation of the top horizontal beam 1 and the bottom horizontal beam 3; the above structure can effectively improve the overall strength, while utilizing the light transmittance of the glass ribs 7 to ensure the overall transparency; it solves the problem of ensuring both safety and transparency in large-segment double-layer curtain walls.

[0101] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
