Description

Technical Field

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

[0002] A glass curtain wall is a modern building envelope or decorative structure, consisting of a supporting structure and glass panels. Due to its lightweight and aesthetically pleasing nature, glass curtain walls are widely used in modern high-rise buildings.

[0003] However, glass has poor thermal insulation properties, far lower than building materials such as concrete. When buildings with glass curtain walls are exposed to sunlight, the sunlight directly heats the interior, causing the indoor temperature to rise rapidly, affecting the indoor cooling efficiency and resulting in a huge waste of energy.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0009] A lever arm is provided at the top of the main building; the lever arm extends out of the exterior facade of the main building; at least two lever arms are provided.

[0010] An outer column is vertically arranged; the outer column is connected to the lever arm; an outer glass panel is provided between adjacent lever arms and adjacent outer columns;

[0011] A waterproof cover plate is disposed at the end of the lever arm that is close to the main body of the building; the end of the waterproof cover plate that is away from the lever arm is bent toward the main body of the building.

[0012] The waterproof cover plate is sealed to the outer glass; along the length of the waterproof cover plate, a protrusion is also provided on the top of the main building; the protrusion is located between the lever arm and the bent portion of the waterproof cover plate.

[0013] A further technical solution is that an outer crossbeam is arranged horizontally between adjacent outer columns; a grid plate is arranged between the inner crossbeam and the outer crossbeam.

[0014] A further technical solution is that angle steel is provided on the inner crossbeam; the grating plate is connected to the angle steel.

[0015] A further technical solution is that a limiting member is provided at the end of the outer crossbeam away from the inner crossbeam; a limiting notch is opened on the outer column for the limiting member to be inserted; the upper and lower ends of the outer glass between adjacent outer columns respectively contact the limiting member.

[0016] A further technical solution is to provide a connecting rod between the inner crossbeam and the outer column.

[0017] A further technical solution is that an ear plate is provided on the surface of the inner crossbeam near the outer column; a connecting hole is provided on the outer column parallel to the length direction of the inner crossbeam; one end of the connecting rod is rotatably connected to the ear plate by a pin, and the other end of the connecting rod is provided with a pin to rotatably connect to the column along the connecting hole.

[0018] A further technical solution is that, along the horizontal direction, a first slot is provided on the opposite side of the outer column, and a second slot is provided on the opposite side of the lever arm; the outer glass between adjacent outer columns is inserted into the first slot; and the outer glass between adjacent lever arms is inserted into the second slot.

[0019] A further technical solution is that the first and second slots on the connected lever arm and the outer column are aligned.

[0020] A further technical solution is to provide a connecting plate; the connecting plate is threadedly connected to both the lever arm and the outer column.

[0021] A further technical solution is that a third slot is provided on the upper and lower surfaces of the inner crossbeam; the third slots on adjacent inner crossbeams are aligned; and the inner glass is disposed in the third slot.

[0022] The beneficial technical effects of this utility model are as follows:

[0023] (1) The double-layer curtain wall system of this utility model, in addition to the inner glass installed on the main body of the building, also has an outer glass installed on the outer side of the main body of the building. The double-layer glass improves the thermal insulation performance of the curtain wall. Moreover, the outer columns are connected to the main body of the building through lever arms that extend out of the outer facade of the main body of the building, so that an air buffer layer is formed between the outer glass and the inner glass. The outer glass is connected to the main body of the building through lever arms, and there are gaps between adjacent lever arms for air circulation. After the air between the outer glass and the inner glass is heated by sunlight, it rises and is discharged along the gaps between adjacent lever arms, reducing the transfer of heat to the interior. In addition, a waterproof cover plate and a protrusion are also provided between the lever arm and the main body of the building. A watertight ventilation opening is formed between the waterproof cover plate and the protrusion. The waterproof cover plate prevents rainwater and foreign objects from falling directly into the double-layer curtain wall system, and the protrusion prevents rainwater and foreign objects on the main body from flowing directly into or rolling into the double-layer curtain wall system, thereby improving the sealing performance of the double-layer curtain wall system.

[0024] (2) Further, a grid plate is provided between the inner and outer crossbeams. The grid plate supports the outer crossbeam and the outer column and does not obstruct the air flow between the inner and outer glass, so that the high temperature air between the inner and outer glass can flow out through the watertight ventilation opening.

[0025] (3) Furthermore, a connecting rod is provided between the inner beam and the outer column to connect and fix the inner beam and the outer column, thereby improving the structural strength of the entire double-layer curtain wall system. Attached Figure Description

[0034] Figure 1 A schematic diagram of the left-side structure of a double-layer curtain wall system according to an embodiment of the present disclosure is shown. Figure 2 A three-dimensional structural schematic diagram of a double-layer curtain wall system according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2 The double-layer curtain wall system includes inner horizontal beams 2, of which at least two are installed. The inner horizontal beams 2 are horizontally positioned on the exterior facade of the main building 1. Inner glass 7 is installed between adjacent inner horizontal beams 2. Lever arms 3 are installed at the top of the main building 1. Lever arms 3 extend beyond the exterior facade of the main building 1. At least two lever arms 3 are installed. External columns 4 are vertically installed. External columns 4 are connected to the lever arms 3.

[0035] Double-glazed windows enhance the thermal insulation performance of the curtain wall. The outer columns are connected to the main building 1 via lever arms 3 extending from the building's facade, creating an air buffer layer between the outer glass 8 and the inner glass 7. The outer glass 8 is positioned between adjacent lever arms 3 and adjacent outer columns 4. The outer glass 8 is fixed to the main building 1 via lever arms 3, with gaps between adjacent lever arms 3 allowing for air circulation. When the air between the outer glass 8 and the inner glass 7 is heated by sunlight, it rises and escapes through the gaps between adjacent lever arms 3, reducing heat transfer to the interior. A waterproof cover plate 31 is located at the end of the lever arm 3 closest to the main building 1. The end of the waterproof cover plate 31 away from the lever arm 3 bends towards the main building 1.

[0036] The waterproof cover plate 31 is sealed to the outer glass 8. A protrusion 11 is also provided on the top of the main building 1 along the length of the waterproof cover plate 31. The protrusion 11 is located between the lever arm 3 and the bend of the waterproof cover plate 31. A watertight ventilation opening 311 is formed between the waterproof cover plate 31 and the protrusion 11. The waterproof cover plate 31 prevents rainwater and foreign objects from directly entering the double-layer curtain wall system, and the protrusion 11 prevents rainwater and foreign objects on the main building 1 from directly flowing into or rolling into the double-layer curtain wall system, thereby improving the sealing performance of the double-layer curtain wall system.

[0037] Figure 3 A cross-sectional view at point A is shown of a double-layer curtain wall system according to an embodiment of this disclosure. Please refer to... Figure 2 and Figure 3 An outer crossbeam 5 is horizontally installed between adjacent outer columns 4. A grating plate 52 is installed between the inner crossbeam 2 and the outer crossbeam 5. The grating plate 52 supports the outer crossbeam 5 and the outer column 4, and does not obstruct the airflow between the inner glass 7 and the outer glass 8, allowing the high-temperature air between the inner glass 7 and the outer glass 8 to flow out through the watertight vent 311.

[0038] Preferably, an angle steel 22 is provided on the inner crossbeam 2, and the angle steel 22 is welded to the inner crossbeam 2. The grating plate 52 is connected to the angle steel 22. The grating plate 52 can be placed on the angle steel 22, and the connection between the grating plate 52 and the angle steel 22 can be welded or threaded.

[0039] More preferably, a limiting member 51 is provided at the end of the outer crossbeam 5 away from the inner crossbeam 2, and the limiting plate can be welded to the outer crossbeam 5. A limiting notch 42 is provided on the outer column 4 for the limiting member 51 to be inserted, further restricting the position between the outer column 4 and the outer crossbeam 5 and enhancing the connection strength between the outer column 4 and the outer crossbeam 5. The upper and lower ends of the outer glass 8 between adjacent outer columns 4 respectively contact the limiting member 51, and the limiting member 51 positions and supports the outer glass 8.

[0040] Please refer to Figure 1 and Figure 2 A connecting rod 6 is installed between the inner horizontal beam 2 and the outer column 4. The connecting rod 6 connects and fixes the inner horizontal beam 2 and the outer column 4, thereby improving the structural strength of the entire double-layer curtain wall system.

[0041] Preferably, an ear plate 23 is provided on the surface of the inner crossbeam 2 near the outer column 4. The ear plate 23 is welded to the inner crossbeam 2. A connecting hole is provided on the outer column 4 parallel to the length direction of the inner crossbeam 2. One end of the connecting rod 6 is rotatably connected to the ear plate 23 via a pin, and the other end of the connecting rod 6 is provided with a pin to rotatably connect to the column along the connecting hole. The rotatable connection between the connecting rod 6 and the inner crossbeam 2, and the rotatable connection between the connecting rod 6 and the outer column 4, can meet the parallel displacement requirements between the inner crossbeam 2 and the outer column 4.

[0042] More preferably, the upper and lower surfaces of the inner crossbeam 2 are respectively provided with third slots 21. The third slots 21 on adjacent inner crossbeams 2 are aligned. The inner glass 7 is disposed in the third slot 21. The adjacent inner crossbeams 2 restrict the position of the inner glass 7 through the third slots 21.

[0043] Figure 4 A partially enlarged view of a double-layer curtain wall system according to an embodiment of this disclosure is shown at point B. Please refer to... Figure 1 , Figure 2 and Figure 4 Along the horizontal direction, a first slot 41 is provided on the opposite side of the outer column 4, and a second slot 32 is provided on the opposite side of the lever arm 3. The outer glass 8 between adjacent outer columns 4 is inserted into the first slot 41. The outer glass 8 between adjacent lever arms 3 is inserted into the second slot 32. The first slot 41 restricts the relative position between the outer glass 8 and the outer column 4, and the second slot 32 restricts the relative position between the outer glass 8 and the lever arm 3.

[0044] Preferably, the first slot 41 and the second slot 32 on the connecting lever arm 3 and the outer column 4 are aligned. This facilitates seamless splicing of the outer glass 8 within the first slot 41 and the second slot 32, improving the sealing performance of the entire double-layer curtain wall system.

[0045] More preferably, a connecting plate 33 is also provided. The connecting plate 33 is threadedly connected to both the lever arm 3 and the outer column 4, thereby connecting the lever arm 3 and the outer column 4. Specifically, a bolt group 34 is provided on the connecting plate 33. Multiple bolts in the bolt group 34 cooperate with each other to fix the lever arm 3 and the connecting plate 33, as well as the lever arm 3 and the outer column 4.

[0046] The specific workflow of this utility model is as follows:

[0047] When sunlight shines on the double-layer curtain wall system, it first illuminates and heats the outer glass 8 and the air buffer layer (not shown in the figure) between the inner glass 7 and the outer glass 8. The temperature of some of the gas inside the air buffer layer gradually increases. This high-temperature gas moves upward along the gap between the inner glass 7 and the outer glass 8 and passes through the grid plate 52 until it reaches the lever arm 3. Then, the high-temperature gas flows out through the gap between the lever arm 3, the waterproof cover plate 31, and the main building 1. While the high-temperature gas flows out, the lower ends of the inner glass 7 and the outer glass 8 are continuously replenished with ambient temperature gas from the outside, thereby preventing the heat from the outer glass 8 from being transferred to the interior.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
