Description

Technical Field

[0001] This application relates to the field of curtain wall technology, and in particular to a glass curtain wall anti-self-explosion structure. Background Technology

[0002] A curtain wall is the exterior wall cladding of a building, also known as a "curtain wall," and is a lightweight wall structure commonly used in modern architecture for its decorative effect. It mainly consists of panels and a supporting structural system. The panels are connected to the exterior wall through the supporting structural system and are laid on the outer side of the exterior wall. Common panel materials include glass and stone, used in various applications. Glass curtain walls, in particular, are widely used due to their smooth appearance and minimal impact on the interior. However, because glass curtain walls are installed on the exterior facade of a building, the glass is directly exposed to direct sunlight and direct contact with outside air. In summer, the glass temperature can be relatively high due to direct sunlight; conversely, in winter, direct contact with cold outside air can result in a relatively low glass temperature.

[0003] For exposed-frame glass curtain walls, the edges of the glass are clamped inside the frame and sealed with sealant to achieve a waterproof effect. In summer, this can lead to uneven heating between the edges and the center of the glass, resulting in different degrees of thermal expansion and contraction between the edges and the center. Similarly, in winter, because the edges are inside the frame, they tend to be warmer, causing the edges to expand and contract at a different rate than the center. Therefore, over long-term use, this uneven thermal expansion and contraction can easily cause the glass to crack.

[0004] To mitigate the problem of glass cracking, existing technologies often employ explosion-proof glass in glass curtain wall construction. These methods primarily include: one involves coating the glass panel with an explosion-proof film to increase its crack resistance; another is laminated glass, which uses a transparent film sandwiched between multiple layers of glass panels to further enhance crack resistance; and a third method involves improving the glass panel's manufacturing process to enhance its inherent crack resistance. However, in practical use, these methods significantly increase the cost of the glass panels, and the panels remain susceptible to cracking due to thermal expansion and contraction. Therefore, further reducing the risk of glass panel cracking is a pressing issue that needs to be addressed in glass curtain wall construction. Summary of the Invention

[0005] To further reduce the risk of glass panels cracking, this application provides a glass curtain wall anti-spontaneous explosion structure.

[0006] This application provides a glass curtain wall anti-spontaneous explosion structure, which adopts the following technical solution:

[0007] A glass curtain wall anti-spontaneous explosion structure includes a horizontal beam for connecting the exterior wall and a glass panel. The edge of the glass panel is fastened to the horizontal beam by a fastener and sealed with waterproof adhesive. The fastener has a vertically extending buffer cavity inside. The cavity wall of the buffer cavity has several connecting holes. Some of the connecting holes connect the buffer cavity to the space outside the glass panel, and the remaining connecting holes connect the buffer cavity to the space inside the glass panel.

[0008] By adopting the above technical solution, during use, when the temperature is relatively high, the external airflow enters the buffer cavity through the connecting hole and then flows into the inner side of the glass panel. During this process, the airflow transfers external heat through the cavity wall to the outer edge of the glass, while simultaneously carrying away some heat from the center of the glass panel. This reduces the temperature difference between the edge and center of the glass panel when heated, thereby reducing the possibility of cracking due to heat. Simultaneously, when the temperature is relatively low, the airflow also helps maintain a relatively uniform temperature across different parts of the glass panel, thus achieving optimal performance regardless of whether the glass is heated or not. Cooling can reduce the temperature difference between the edges and center of the glass panel, thereby reducing the difference in thermal expansion and contraction in different parts of the glass panel and reducing the possibility of cracking. Therefore, compared with directly setting a gap between the glass panel and the frame or directly opening a hole in the glass panel, it can effectively reduce the impact on the installation stability of the glass panel, and also reduce the possibility of external rainwater entering the inside of the glass panel. At the same time, the airflow can also balance the uniformity of heating of the glass panel, so that the difference in thermal expansion and contraction in different parts of the glass panel can be effectively reduced, thereby reducing the probability of spontaneous breakage.

[0009] In addition, since the buffer cavity is formed inside the fixing component, when it rains, rainwater will follow the airflow into the buffer cavity, collect and buffer, and then be discharged downward through the fixing component. This can effectively reduce the possibility of rainwater following the airflow into the inside of the glass panel. Furthermore, the airflow can also carry away moisture in time, thereby reducing the formation of condensation on the glass panel.

[0010] Optionally, the fastener includes a fixing seat and a fixing plate. The fixing seat is fixedly connected to the opposite ends of the two sets of crossbeams, and the fixing plate fastens the opposite side edges of the two sets of glass panels to the fixing seat. The buffer cavity is formed in the fixing seat and the fixing plate.

[0011] By adopting the above technical solution, the edge of the glass panel is fastened to the fixing seat by the fixing plate to separate the inner and outer sides of the side edge of the glass panel. At the same time, the fixing seat is connected to the crossbeam, which can realize modular assembly by first installing the fixing seat, then installing the glass panel or fixing plate, and finally installing the fixing plate or glass panel, thereby optimizing the convenience of installing the glass panel.

[0012] Optionally, the fixing base includes a fixing tube and a fixing pad. The fixing tube is fixedly connected to the opposite ends of two sets of crossbeams. The two vertical side edges of the fixing pad are bent towards each other and abut against the fixing tube. The glass panel is clamped between the fixing buckle plate and the fixing pad. The fixing buckle plate and the fixing pad are connected to the fixing tube by a connector.

[0013] By adopting the above technical solution, the fixing pipe is fixedly connected to the two sets of crossbeams, and is connected to the glass panel through the fixing pad as an intermediate buffer. The deformation of the fixing pad can adapt to the angle and spacing of the glass panel relative to the fixing pipe during actual installation.

[0014] Optionally, two sets of heat insulation plates are clamped between the fixing pad, fixing tube, or pad and fixing tube. The two sets of heat insulation plates are set for two sets of glass panels, and the heat insulation plates and the corresponding glass panels are separated by a gap. The connecting hole connecting the inner side of the glass panel is connected to the gap between the heat insulation plate and the glass panel.

[0015] By adopting the above technical solution, the heat insulation board can effectively reduce the influence of the building's internal temperature on the temperature inside the glass panel. On the other hand, when external airflow flows into the inside of the glass panel, it enters the gap between the glass panel and the heat insulation board. At this time, due to the isolation of the heat insulation board, the airflow required for airflow inside the glass panel is effectively reduced, thereby effectively promoting the overall flow of air inside the glass panel and further optimizing the purpose of making the glass panel surface heated evenly through airflow.

[0016] It can also further maintain the temperature of the inside and outside of the glass panel relatively consistent, thereby further reducing the possibility of condensation on the inside of the glass panel.

[0017] Optionally, the fixing plate includes a fixing base plate and a protective plate spaced apart. The fixing base plate is connected to the fixing tube via a connector. The protective plate is fastened to the side edge of the fixing base plate and abuts against the glass panel. The buffer cavity includes several buffer cavity units. The buffer cavity units are formed in the gap between the fixing base plate and the protective plate, the gap between the fixing base plate and the fixing pad, and the gap between the fixing pad and the fixing tube. The connecting hole is opened in the cavity wall of the buffer cavity unit.

[0018] By adopting the above technical solution, the fixed base plate is connected to the fixed pipe through the connector, and the protective plate can protect the connector to reduce the possibility of the connector being directly exposed. At the same time, by using the fixed base plate, protective plate and fixed pad, the buffer cavity is divided into multiple buffer cavity units, which can effectively reduce the possibility of rainwater entering the inside of the glass panel with the airflow. This facilitates installation, optimizes the overall appearance, and further reduces the possibility of the inside of the glass panel being eroded by rainwater.

[0019] Optionally, the connector includes a connecting bolt and a connecting spring. The connecting bolt passes through the fixed base plate, the fixed pad, and the fixed tube and fastens the three together. The two ends of the connecting spring abut against the fixed base plate and the fixed pad, respectively.

[0020] By adopting the above technical solution, the connecting spring can keep the fixed base plate and the fixed pad away from each other during the installation of the glass panel, and restrict their movement through the connector and the fixing tube. This facilitates the installation of the glass panel, and also provides auxiliary support to the fixed base plate when the glass panel is subjected to negative pressure due to airflow after installation, thereby optimizing the stability after installation.

[0021] Optionally, the protective plate and / or the fixed base plate are fixedly connected to two partition plates. The partition plates divide the gap between the protective plate and the fixed base plate into three cavities, and the cavity on the side of the two partition plates that is far apart is a buffer cavity unit. The connector is located between the two partition plates.

[0022] By adopting the above technical solution, the partition plate can separate the cavity between the protective plate and the fixed base plate, thereby reducing the possibility that the airflow will directly contact the connector after entering the gap between the protective plate and the fixed base plate, which could lead to erosion of the connection between the connector and the fixed base plate. At the same time, the partition plate can separate the airflow entering through the connection holes of the two sets of glass panels at the corner of the protective plate, so that the airflow entering the inner side of the protective plate is first buffered by the first buffer chamber unit before mixing, avoiding the impact of airflow convection on the ventilation inside the glass panel.

[0023] Optionally, two sets of sealing strips are provided between the fixing base and the fixing buckle plate, and the two sets of sealing strips are respectively attached to the two sides of the glass panel.

[0024] By adopting the above technical solution, the sealing strip can seal the gap between the glass panel and the fixing seat and the fixing buckle.

[0025] Optionally, the connecting spring is sleeved on the connecting bolt, and the connecting spring sleeve has two connecting pads. The two connecting pads are slidably connected and their opposite ends are bent inward. The connecting bolt passes through the two connecting pads.

[0026] By adopting the above technical solution, the connecting gasket can further protect the part of the connecting bolt located between the fixed pad and the fixed base plate, as well as the connecting spring, so as to reduce the corrosion of the connecting bolt caused by airflow.

[0027] Optionally, the two connecting gaskets are filled with filling columns, which are made of a material that is elastic after curing.

[0028] By adopting the above technical solution, the infill column can further protect the connecting bolts and connecting springs. At the same time, the use of a material that is elastic after curing can reduce the impact on the installation of the glass panel and the fixed buckle plate during installation. After curing, the infill column, together with the connecting spring, supports the fixed base plate, thereby reducing the possibility of a decrease in support effect due to the reduction of elasticity of the connecting spring over a long period of use.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. During use, when the temperature is relatively high, the external airflow enters the buffer chamber through the connecting hole and then flows into the gap between the inner side of the glass panel and the insulation board. During this process, the airflow can transfer external heat through the cavity wall of the buffer chamber to the outer edge of the glass, while carrying away some heat from the middle of the glass panel. This reduces the temperature difference between the edge and the middle of the glass panel when heated, thereby reducing the possibility of cracking due to heat. When the temperature is relatively low, the airflow can also keep the temperature of different parts of the glass panel relatively consistent. This can reduce the temperature difference between the edge and the middle of the glass panel whether it is heated or cooled, thereby reducing the difference in thermal expansion and contraction in different parts of the glass panel and reducing the possibility of cracking.

[0031] 2. In addition, since the buffer cavity is formed inside the fixing component, when it rains, rainwater will follow the airflow into the buffer cavity and be collected and buffered before being discharged downward through the fixing component. This can effectively reduce the possibility of rainwater following the airflow into the inside of the glass panel. Furthermore, the airflow can also carry away moisture in time, thereby reducing the formation of condensation on the glass panel. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This application discloses a structure for preventing spontaneous explosion of a glass curtain wall. (Refer to...) Figure 1 The anti-explosion structure of the glass curtain wall includes a horizontal beam 1 and glass panels 2. The horizontal beam 1 is used to connect the exterior wall, and the glass panels 2 are set one-to-one with the horizontal beam 1. The edges of the two sets of glass panels 2 are fixedly snapped to the two sets of horizontal beams 1 by fasteners 3.

[0038] Reference Figure 1 and Figure 2 The fastener 3 has a buffer cavity 31 formed inside, and the inner wall of the buffer cavity 31 has several connecting holes 311. Some of the connecting holes 311 connect the buffer cavity 31 to the outer space of the glass panel 2; the remaining connecting holes 311 connect the buffer cavity 31 to the inner space of the glass panel 2. This allows the air in the inner and outer spaces of the glass panel 2 to communicate through the buffer cavity 31 and the connecting holes 311 after installation. This allows the heat on the side edge of the glass panel to be carried away by the airflow or heated by the external hot air, thereby reducing the temperature difference between the edge and the center of the glass panel. In addition, when it rains outside, the rainwater carried by the airflow first enters the buffer cavity 31. At this time, the airflow velocity will decrease and intercept the rainwater, reducing the possibility of the airflow directly carrying rainwater into the inner side of the glass panel 2. This reduces the negative impact on the normal sealing installation of the glass panel 2. It also allows the air to flow between the inner and outer sides of the glass panel 2, carrying away moisture from both sides, thus effectively reducing the possibility of condensation on the surface of the glass panel 2.

[0039] Specifically, the fastener 3 includes a fixing base 32 and a fixing plate 33. The fixing base 32 includes a vertically arranged fixing tube 321 and a vertically arranged fixing pad 322. The outer wall of the fixing tube 321 is located between the opposing ends of two adjacent sets of crossbeams 1 and is fixedly connected to the two sets of crossbeams 1. The fixing tube 321 is parallel to the glass panel 2. Preferably, the fixing tube 321 is fixedly connected to the crossbeam 1 by bolts. The fixing pad 322 is located on the outer wall of the fixing tube 321 facing the glass panel 2. The two vertical sides of the fixing pad 322 are bent towards each other, and the bent parts abut against the fixing tube 321, so that the elastic bending and deformation of the fixing pad 322 can adapt to the distance between the glass panel 2 and the crossbeam 1 during installation.

[0040] Reference Figure 1 and Figure 2 Meanwhile, the fixing plate 33 includes a vertically extending fixing base plate 331 and a protective plate 332. The two vertical side edges of the fixing base plate 331 are bent toward the glass panel 2, and the fixing base plate 331 is connected to the fixing tube 321 through the connector 4. The two vertical side edges of the protective plate 332 are bent toward the fixing tube 321 and fastened to the two bent edges of the fixing base plate 331. The fixing base plate 331 is located inside the protective plate 332, so that a cavity is formed between the fixing base plate 331 and the fixing pad 322. During the process of the fixing base plate 331 being connected to the fixing tube 321 through the connector 4, the edge of the protective plate 332 can also be pressed against the glass panel 2 to optimize the overall stability.

[0041] The buffer cavity 31 includes several buffer cavity units 312, which are formed in the cavity between the fixed base plate 331 and the protective plate 332, the cavity between the fixed base plate 331 and the fixed pad 322, and the cavity between the fixed pad 322 and the fixed tube 321. Furthermore, the connecting holes 311 are opened in the cavity wall of the buffer chamber unit 312, that is, the connecting holes 311 are opened on the two vertical side edges of the protective plate 332 and the fixed base plate 331 and the two side edges of the fixed pad 322. The connecting holes 311 located on the same side edge of the fixed pad 322 are divided into two groups. The side edge of the glass panel 2 is located between the two groups of connecting holes 311, so that the external airflow can pass through the protective plate 332, the fixed base plate 331 and the fixed pad 322 from the outside of the glass panel 2 and enter the inside of the glass panel 2. This allows for timely ventilation of the inside of the glass panel 2, keeping the temperature at the outer edge and the middle of the glass panel 2 relatively consistent, reducing the possibility of the glass panel 2 cracking. At the same time, the protective plate 332 can also protect and isolate the fixed base plate 331.

[0042] Reference Figure 1 and Figure 2To further optimize the timeliness of airflow inside the glass panel 2, a heat insulation plate 323 parallel to it is also provided on the inner side of the glass panel 2. The side edge of the heat insulation plate 323 is engaged with the bent part of the fixing pad 322, the outer wall of the fixing tube 321, or the gap between the fixing pad 322 and the fixing tube 321. In this embodiment, the heat insulation plate 323 is clamped between the fixing pad 322 and the fixing tube 321 and is sealed by the sealing strip 34 so that the fixing pad 322 abuts against the fixing tube 321 through the heat insulation plate 323. Furthermore, the heat insulation board 323 and the glass panel 2 are spaced apart, with a gap of 15-30mm. This allows external air to enter the gap between the glass panel 2 and the heat insulation board 323, thus promoting airflow and reducing the possibility of excessive temperature differences between the side edges and the center of the glass panel 2 due to insufficient airflow. At the same time, the heat insulation board 323 also reduces heat exchange between the inner side of the glass panel 2 and the building's exterior wall, further reducing the impact of the building's exterior wall temperature on the glass panel 2 and meeting the requirements for thermal insulation and energy saving.

[0043] The heat insulation board 323 can be a transparent insulation board, double-glazed glass, or triple-glazed glass. In this embodiment, it is triple-glazed glass, which can achieve relatively good energy-saving effect while maintaining a relatively good appearance. At this time, due to the separation of the glass panel 2 and the heat transfer of multiple buffer cavity units 312, the air temperature in contact with the heat insulation board 323 is relatively consistent, which can reduce the occurrence of excessively high or low temperatures. Thus, the temperature of the side edge of the heat insulation board 323 can be kept relatively consistent with the temperature of the center, and the uneven heating of the heat insulation board 323 is relatively low. Of course, in order to further reduce the possibility of explosion, in other embodiments, the heat insulation board 323 can also be a transparent insulation board.

[0044] In addition, in order to reduce the possibility of rainwater entering the inside of the glass panel 2 when it rains, a set of sealing strips 34 that are locked in the bend of the protective plate 332 are also provided between the bend of the protective plate 332 and the glass panel 2; a set of sealing strips 34 that are locked in the edge of the fixed pad 322 are also provided between the bend of the fixed pad 322 and the glass panel 2, so as to achieve a sealing effect.

[0045] Finally, refer to Figure 1 and Figure 2Since the fixed base plate 331 is connected to the fixed pipe 321 via the connector 4, in order to protect the portion of the connector 4 located between the fixed base plate 331 and the protective plate 332, two partition plates 333 are fixedly connected to the protective plate 332 and / or the fixed base plate 331. Preferably, in this embodiment, both the protective plate 332 and the fixed base plate 331 are fixedly connected to two partition plates 333. The two partition plates 333 on the protective plate 332 are respectively attached to the outer wall of the inner side of the two partition plates 333 on the fixed base plate 331, and the connector 4 is located inside the two partition plates 333 on the fixed base plate 331. This allows airflow mixed with rainwater to enter the gap between the protective plate 332 and the fixed base plate 331, which can be separated by the partition plates 333, thereby providing protection for the connector 4. The cavity on the side of the two partition plates 333 on the fixed base plate 331 that is far apart is a buffer cavity unit 312.

[0046] Of course, in other embodiments, the fastener 3 can also be integrally formed into a tubular structure and fixedly connected to the opposing ends of the two sets of crossbeams 1. The outer wall of the fastener 3 is formed with a groove for snapping onto the glass panel 2. The connecting hole 311 is opened in the fastener 3 and is divided into two sets located on the inner and outer sides of the glass panel 2 to realize the air flow between the inner and outer sides of the glass panel 2.

[0047] Specifically, refer to Figure 2 and Figure 3 The connector 4 includes a connecting bolt 41 and a connecting spring 42. The connecting bolt 41 passes through the walls of the fixed base plate 331, the fixed pad 322, and the fixed pipe 321, and fastens the fixed base plate 331, the fixed pad 322, and the fixed pipe 321 to achieve a detachable connection between the fixed buckle plate 33 and the fixed seat 32. At the same time, the connecting bolt 41 is located between the two partition plates 333 on the fixed base plate 331.

[0048] A connecting spring 42 is sleeved on a connecting bolt 41, and its two ends abut against a fixed base plate 331 and a fixed pad 322 respectively via connecting pads 43. The connecting bolt 41 is coaxially inserted through the connecting pads 43, and two connecting pads 43 are provided on the same connecting bolt 41. The connecting pads 43 are sleeved on the connecting spring 42, and the edges of the opposite ends of the connecting pads 43 are bent inwards. The connecting spring 42 abuts against the bent portion of the connecting pad 43. Simultaneously, one connecting pad 43 is inserted into and slidably connected to the other connecting pad 43, providing protection for the connecting spring 42 and the connecting bolt 41, while also serving as an auxiliary guide. Furthermore, the abutment of the connecting spring 42 assists in supporting the fixed base plate 331 and the fixed pad 322, and ensures that the fixed pad 322 remains tightly fitted to the fixed pad 321 during installation, facilitating installation.

[0049] Furthermore, to further protect and support the connecting spring 42 while minimizing interference during the installation of the glass panel 2, the inner walls of the two connecting gaskets 43 are formed with filler columns 431, which are cured using a filler material. The filler columns 431 are made of a material that is malleable before curing and elastic after curing, such as modified silane adhesive or expanding sealant. After installation or during installation, the filler material is simply filled into the two connecting gaskets 43 and cured. This minimizes the impact on construction and also isolates the connecting spring 42 from external air after installation, further optimizing post-installation stability.

[0050] Finally, refer to Figure 2 and Figure 3 To further optimize post-installation stability and reduce corrosion of the fastener 3 due to relatively sufficient airflow, the crossbeam 1 and the fastener 3 are both made of alloy, preferably steel. Simultaneously, the bent edges of the connecting pipe 43 are also made of steel, while the wall of the connecting pipe 43 is made of a metal with higher reducibility than the crossbeam 1 and the fastener 3 as a whole, such as aluminum. The connecting pipe 43 is also equipped with cables for connecting to the ground, so that when the fastener 3 and the crossbeam 1 come into contact with rainwater and corrode, protection can be provided by sacrificing the wall of the connecting pipe 43.

[0051] Reference Figure 2 and Figure 3 A separator 35 is provided between the fixing pad 322 and the fixing tube 321. The separator 35 includes a separator tube 351 that abuts against the fixing pad 322 and two insulating heat pipes 352. A connecting bolt 41 passes through the separator tube 351 and is located between the two insulating heat pipes 352. The two sides of the insulating heat pipes 352 along their length are respectively engaged with the separator tube 351 and the fixing tube 321. The insulating heat pipes 352 are made of elastic material to ensure that the separator tube 351 fits against the fixing pad 322, and also to further protect the connecting bolt 41 through the insulating heat pipes 322 and the separator tubes 351, reducing erosion from external airflow and reducing the transfer of internal and external heat energy. The separator tube 351 and the side edge of the heat insulation plate 323 are sealed with sealant to further reduce the heat exchange between the internal and external parts.

[0052] The implementation principle of this application embodiment is as follows: During use, the airflow inside and outside the glass panel 2 can be realized through the buffer cavity unit 312 and the connecting hole 311, so that external heat can be transferred to the side edge of the glass panel 2 and the heat insulation plate 323 through the fixed base plate 331, the protective plate 332 and the fixed pad 322, or the heat of the side edge of the glass panel 2 and the heat insulation plate 323 can be carried away, so as to keep the temperature of the outer edge of the glass panel 2 and the heat insulation plate 323 relatively consistent with the middle position, thereby reducing the possibility of cracking.

[0053] At the same time, it can also reduce the temperature difference inside the glass panel 2, thereby reducing the condensation caused by the temperature difference and allowing the moisture on the surface of the glass panel 2 to evaporate in time, thus reducing the possibility of excessive dirt caused by mold growth on the glass panel 2; the buffer cavity 31 is set on the fixing member 3, which can effectively reduce the impact on the installation stability of the glass panel 2, so as to maintain the stability of the glass panel 2 and reduce the possibility of excessive dirt growth on the glass panel 2 due to mold growth.

[0054] In addition, the protection provided by the connecting pad 43 and the partition plate 333 can effectively reduce the corrosion caused by the contact of the fastener 3 and the crossbeam 1 with airflow and rainwater, thereby optimizing the stability after installation.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
