Description

Technical Field

[0001] This invention relates to the field of curtain wall lightning protection construction technology, specifically to a curtain wall lightning protection system for glass curtain walls in high-rise buildings. Background Technology

[0002] Compared to traditional masonry exterior walls, glass curtain walls offer advantages such as lightweight design, strong architectural expression, and rapid construction, leading to their increasingly popular application in building exterior decoration. They are typically installed within the building structure. However, this widespread use has also raised concerns about the safe use of building structures during thunderstorms. The metal components of the glass curtain wall (columns, beams, etc.) are located on the outer surface of the main building, making them highly susceptible to direct or induced lightning strikes. Inadequate lightning protection measures can allow powerful lightning currents to be introduced into the interior through the curtain wall, posing a threat to personnel safety, and particularly damaging expensive and sensitive electronic equipment in computer rooms, leading to data loss and significant economic losses. Therefore, it is necessary to install lightning protection structures within the building structure. Existing lightning protection methods for curtain walls primarily achieve equipotential bonding by placing a single conductor between the metal components (columns) of the curtain wall and the lightning protection down conductors or equipotential rings within the main building structure.

[0003] 1) The lead wires need to be connected via a down conductor and an equalizing ring, which makes the connection method relatively complicated and prone to poor contact;

[0004] 2) Lightning protection connection methods often use a single conductor (such as flat steel) to connect the curtain wall components to the main building structure. This can lead to problems such as excessive resistance in the conductive path or insufficient connection reliability. Excessive contact resistance can affect the efficiency of lightning current discharge.

[0005] 3) Welded joints and exposed connectors in the lightning protection system are exposed to harsh outdoor environments for a long time, making them highly susceptible to corrosion. This not only affects the aesthetics but also seriously weakens the stability of the conductive path of the lightning protection system, posing a hidden danger to long-term safety. Summary of the Invention

[0006] The technical problem to be solved by this invention is to address the deficiencies of existing technologies by providing a high-rise building structure that conducts lightning strikes on the glass curtain wall to the ground during thunderstorms, thereby protecting the glass curtain wall from lightning damage. This effectively solves the problem of lightning protection access in the glass curtain wall area, significantly reduces the risk of lightning strikes, ensures the safety of personnel and equipment (especially in data center areas), effectively protects the glass curtain wall and power distribution equipment of super high-rise buildings, and guarantees the safety of high-rise building structures in use.

The embedded parts 21 are welded to the main building structure 3 so that the embedded parts 21 are welded to the equipotential bonding strip of the main building structure 3. One end of the intermediate conductor 23 is connected to the lower part of the column 111 of the glass curtain wall 11, and the other end of the intermediate conductor 23 is connected to the embedded parts 21. One end of the connecting conductor 22 is welded to the embedded parts 21, and the other end of the connecting conductor 22 is connected to the intermediate conductor 23 so that the connecting conductor 22 is connected to the column 111 of the glass curtain wall 11 through the intermediate conductor 23. The curtain wall lightning protection system 2 of the present invention includes connecting parts 25, and the conductive connecting pieces 24 are connected to the core column 1111 of the column 111 through the connecting parts 25. In specific implementation, the connecting parts 25 are stainless steel self-tapping locking screws. One end of the conductive connecting piece 24 is connected to the column 111 of the glass curtain wall 11, and the other end of the conductive connecting piece 24 is connected to the intermediate conductor 23. The column 111 of the glass curtain wall 11 forms a lightning protection current path with the main building structure 3 through the conductive connecting piece 24, the intermediate conductor 23, the connecting conductor 22.In practice, the embedded part 21 is made of Q235 steel with a thickness of 12mm. The embedded part 21 is fixed to the reinforced concrete beams or columns of the main building structure 3 by welding, with a welding length of not less than 100mm. The embedded part 21 is welded to the equipotential bonding strip (foundation steel mesh) within the main building structure 3. The embedded part 21 and the welding point are treated with anti-corrosion measures to ensure reliable equipotential bonding between the embedded part 21 and the main building structure 3. The intermediate conductor 23 uses a 5mm thick steel angle bracket. One end of the intermediate conductor 23 is connected to the lower part of the column 111 of the glass curtain wall 11 via an M10 stainless steel bolt. Spring washers are installed at the bolt connection to prevent loosening. The other end of the intermediate conductor 23 is connected to the embedded part 21. In practice, conductive paste can be applied to the connection point to reduce [the risk of damage]. Contact resistance; the connecting conductor 22 is made of hot-dip galvanized round steel with a diameter of Φ10mm. One end of the connecting conductor 22 is fully welded to the embedded part 21, and the welding length is not less than 10 times the diameter of the round steel, i.e., 100mm. After welding, the welding slag is removed and an anti-corrosion layer is applied. The other end of the connecting conductor 22 is welded to the intermediate conductor 23, and the welding method is also full welding to ensure a firm connection. The conductive connecting piece 24 is made of 2.5mm thick aluminum alloy plate and is set as a bent plate structure. The corners at the bends are rounded to avoid stress concentration. One end of the conductive connecting piece 24 is connected to the column 111 of the glass curtain wall 11 through the connector 25, and the other end is connected to the intermediate conductor 23 through bolts. The surface of the conductive connecting piece 24 at the connection part is polished to remove the oxide layer and ensure good conductivity.

[0039] In this embodiment of the invention, when the glass curtain wall 11 is struck by lightning, the lightning current is conducted through the column 111 of the glass curtain wall 11 to the conductive connecting piece 24. The conductive connecting piece 24 transmits the current to the intermediate conductor 23. At the same time, the intermediate conductor 23 is connected to the embedded part 21 through the connecting conductor 22. The current is conducted through the intermediate conductor 23 and the connecting conductor 22 to the embedded part 21. The embedded part 21 is connected to the equipotential bonding strip of the main building structure 3. Finally, the lightning current is conducted to the ground through the main building structure 3, forming a complete and reliable lightning protection current path. In thunderstorms, the lightning received by the glass curtain wall 11 is conducted to the ground, which plays a role in lightning protection for the glass curtain wall 11. This effectively solves the problem of lightning protection access in the area of ​​the glass curtain wall 11, significantly reduces the risk of lightning strikes, ensures the safety of personnel and equipment (especially the data center area 33), and ensures the safety of the high-rise building structure.

[0040] The present invention applies an anti-corrosion layer to the welding area connecting the conductor 22 and the embedded part 21. Specifically, the anti-corrosion layer is red lead anti-rust paint. By setting the anti-corrosion layer, the durability of the welding area connecting the conductor 22 and the embedded part 21 in harsh environments can be improved, maintenance costs can be reduced, and long-term lightning protection reliability can be guaranteed.

[0041] In practice, a core column 1111 is provided inside the column 111 of the glass curtain wall 11. The core column 1111 has an opening, and a conductive connecting piece 24 is located on the outside of the column 111. One end of the conductive connecting piece 24 is connected to the core column 1111 of the column 111, and the other end of the conductive connecting piece 24 is connected to the intermediate conductor 23. The combined structure formed by the core column 1111 and the column 111 simultaneously bears the load of the glass curtain wall 11.

[0042] In this embodiment of the invention, the glass curtain wall 11 includes columns 111, double-glazed windows 112, fixing components 113 for fixing the columns 111, two sets of thermal insulation strips 114, column front members 115, crossbeams 116, connecting bolts 117, aluminum alloy frames 118, and fasteners 119. The crossbeams 116 are connected to the exterior wall 31 of the main building structure. The columns 111 are installed on the crossbeams 116 via the fixing components 113. The column front members 115 are installed on one side of the columns 111 via the fasteners 119. The two sets of thermal insulation strips 114... Two sets of thermal insulation strips 114 are spaced apart between the columns 111 and the column front member 115. One end of each set of thermal insulation strips 114 is connected to the column 111, and the other end of each set of thermal insulation strips 114 is connected to the column front member 115. An installation cavity for installing glass is formed between the aluminum alloy frame 118 and the column 111. Connecting bolts 117 pass through the middle of the aluminum alloy frame 118 and the column front member 115 in sequence to install the aluminum alloy frame 118 onto the column 111. Double-glazed insulated glass 112 is installed in the installation cavity between the aluminum alloy frame 118 and the column 111. By setting thermal insulation strips, the glass curtain wall 11 effectively blocks the conduction of heat between the indoor and outdoor spaces, isolates heat conduction and loss, and minimizes heat conduction and loss, thus achieving better thermal insulation capacity and improving the overall energy-saving effect of the glass curtain wall 11. In specific implementation, the columns 111 of the glass curtain wall 11 are aluminum alloy columns 111, the crossbeam 116 is also an aluminum alloy crossbeam 116, the connecting bolts 117 can be stainless steel hexagonal head bolts, the fasteners 119 are M4x25 stainless steel bolts, and bolt holes that mate with the fasteners 119 and connecting bolts 117 are provided at the upper and lower ends of the column front member 115, respectively. The fixing bolts 1132 of the fixing assembly 113 can be M6x110 stainless steel bolts. The columns 111 and crossbeams 116 are fixed by using connecting brackets 1131 and fixing bolts 1132, which not only provides good connection stability but also makes the installation of the glass curtain wall 11 more convenient. Flexible damping pads 1133 are placed between the connecting brackets 1131 and the columns 111, and the flexible damping pads 1133 can play an auxiliary role in earthquake resistance.

[0043] The aluminum alloy frame 118 of the present invention includes an aluminum alloy buckle cover 1181 and an aluminum alloy pressure plate 1182. The aluminum alloy buckle cover 1181 is located at one end of the aluminum alloy pressure plate 1182 and connected to it. The other end of the aluminum alloy pressure plate 1182 forms an insertion groove 11821. A sealing strip 1183 is inserted into the insertion groove 11821. The sealing strip 1183 is pasted between the insertion groove 11821 of the aluminum alloy pressure plate 1182 and the double-glazed insulated glass 112. EPDM rubber strips can be used for 1183. The aluminum alloy pressure plate 1182 is fixed to one side of the double-glazed glass 112 via the sealing strip 1183 of the insertion groove 11821. The middle of the aluminum alloy pressure plate 1182 is connected to the column front member 115 via connecting bolts 117. Glass sealant 120 is also provided between the double-glazed glass 112 and the column 111. The other side of the double-glazed glass 112 is fixed to the column 111 via glass sealant 120. An aluminum alloy cover 1181 is connected to the aluminum alloy pressure plate 1182. The aluminum alloy cover 1181 serves to conceal the column front member 115 and the connecting bolts 117, making the glass curtain wall 11 more aesthetically pleasing, while also saving costs, facilitating installation, and simplifying construction. In a specific implementation, snap-fit ​​connectors 11811 are provided at both ends of the aluminum alloy cover 1181, and a limiting plate 11812 is provided at the end near the snap-fit ​​connectors 11811. Snap-fit ​​grooves are provided at both ends of the aluminum alloy pressure plate 1182, and a snap-fit ​​block 11822 is provided at the end near the snap-fit ​​grooves. The aluminum alloy cover 1181 is snapped into the snap-fit ​​grooves of the aluminum alloy pressure plate 1182 through the snap-fit ​​connectors 11811 at both ends. The limiting plate 11812 on the aluminum alloy cover 1181 abuts against the snap-fit ​​block 11822 on the aluminum alloy pressure plate 1182, restricting the displacement of the aluminum alloy cover 1181 in the direction toward the aluminum alloy pressure plate 1182.

[0044] In this embodiment of the invention, the double-glazed insulating glass 112 includes a first glass plate 1121, a second glass plate 1122, a spacer 1123, a sealing layer 1124, and a Low-E coating layer 1125. The first glass plate 1121 and the second glass plate 1122 are arranged parallel to each other. The spacer 1123 is disposed in the edge region between the first glass plate 1121 and the second glass plate 1122. The spacer 1123, together with the first glass plate 1121 and the second glass plate 1122, enclose a hollow cavity 1126. The sealing layer 1124 is disposed in the hollow cavity 1126 between the first glass plate 1121 and the second glass plate 1122. The Low-E coating layer 1125 is disposed on the surface of the first glass plate 1121 facing the hollow cavity 1126 or on the surface of the second glass plate 1122 facing the hollow cavity 1126. By applying a Low-E coating layer 1125 to the surface of the first glass panel 1121 or the second glass panel 1122 facing the hollow cavity 1126, the Low-E coating layer 1125 can effectively reflect far-infrared heat radiation from indoors or outdoors, significantly reducing heat conduction through the double-glazed insulated glass 112, thereby greatly improving the heat insulation performance of the glass. The sealing layer 1124 includes a foam rod 11241 and a weather-resistant sealant 11242. The foam rod 11241 is disposed in the gap between two adjacent double-glazed insulated glass panels 112, and the weather-resistant sealant 11242 fills the outside of the foam rod 11241. The thermal insulation strip 114 is selected from PA66GF25 thermal insulation strip 114. The PA66GF25 thermal insulation strip 114 used is composed of polyamide 66 (PA66) and 25% glass fiber (GF), which has good thermal insulation performance, can effectively block heat conduction, reduce the transfer of heat between different temperature environments, help maintain the stability of indoor temperature, and reduce energy consumption.

[0045] In other embodiments, the thermal insulation strip 114 may also be a nylon 66 thermal insulation strip 114.

[0046] The fixing component 113 provided in this invention includes a connecting bracket 1131 and a fixing bolt 1132. The column 111 and the crossbeam 116 are connected by the connecting bracket 1131 and the fixing bolt 1132. A flexible shock-absorbing pad 1133 is provided between the connecting bracket 1131 and the outer wall of the column 111.

[0047] In this embodiment of the invention, the steel structure glass canopy 13 includes a canopy steel beam 131, a glass canopy panel 132, an embedded part 133, and a canopy fixing assembly 134. The glass canopy panel 132 is installed on the top of the canopy steel beam 131 through the canopy fixing assembly 134. One end of the canopy steel beam 131 is fixedly connected to the outer wall 31 of the main building structure 3 through the embedded part 133. Specifically, the canopy steel beam 131 includes a vertical steel beam and a horizontal steel beam connected to the top of the vertical steel beam. The embedded part 133 is a chemical anchor. In practical implementation, the glass canopy panel 132 of this invention is made of high-strength, light-transmitting glass, which can maximize the introduction of natural light into the space below the canopy (such as building entrance passages, areas under balconies, etc.), avoiding the problem of dark spaces below traditional metal and plastic canopies requiring additional lighting equipment, thus reducing energy consumption. It also improves the lighting effect and comfort of the space below. Furthermore, the transparent or semi-transparent glass canopy panel can blend seamlessly with the exterior design of the building's main structure, showcasing a simple and modern visual effect, enhancing the overall aesthetics and sophistication of the building. The canopy steel beam 131, with its H-shaped cross-section design, offers significant advantages in terms of moment of inertia and section modulus compared to traditional T- or rectangular cross-section steel beams. Particularly when dealing with upward wind pressure, the H-shaped beam 131 effectively disperses wind loads, evenly distributing the upward wind pressure throughout the beam and its connection to the main building. This significantly improves the canopy's resistance to upward wind pressure, preventing deformation, bending, or even breakage of the steel beam due to strong winds. It also significantly enhances the structural stability and safety of the canopy under severe weather conditions (such as typhoons and strong gusts), reducing the risk of the steel beam being lifted by wind pressure. Furthermore, the H-shaped structure of the canopy steel beam 131 effectively reduces material usage and weight compared to solid steel beams or other complex cross-section steel beams with equivalent load-bearing capacity. This not only reduces the overall load on the main building structure but also prevents excessive weight from causing additional loads on the exterior walls and foundations, extending the service life of the main building structure. Embedded parts 133 are set as connecting components between the canopy steel beam 131 and the exterior wall 31 of the main building structure 3. By pre-embedding them inside the main building structure 3 and tightly integrating them with the steel bars, concrete, and other structures of the main building structure 3, a solid connection foundation is formed. Compared with traditional surface mounting and simple bolt fixing connection methods, embedded parts 133 can effectively and evenly transfer the load (including the weight of the canopy itself and the weight of the glass canopy panels) transmitted by the canopy steel beam 131 to the main building structure 3, avoiding load concentration that could cause the connection to loosen or fall off. This ensures the firmness and stability of the connection between the H-shaped canopy steel beam 131 and the main building structure 3, realizing the integration of the canopy steel beam 131 and the main building structure 3, and significantly improving the overall structural safety factor of the steel structure glass canopy 13.

[0048] In other embodiments, mounting steel plates can be installed on the exterior wall 31 of the main building structure 3 at positions corresponding to each canopy steel beam 131. The mounting steel plates are anchored to the exterior wall 31 of the main building structure 3 by chemical anchors. The canopy steel beam 131 is welded to the corresponding mounting steel plate to achieve the fixation of the steel structure glass canopy 13 to the exterior wall 31 of the main building structure 3.

[0049] In a specific implementation, the canopy fixing component 134 includes a fixing frame 1341, a fixing plate 1342, a stainless steel plate 1343, and an adhesive 1344. The adhesive 1344 is disposed between the fixing frame 1341 and the glass canopy panel 132. The glass canopy panel 132 is fixed to the top of the fixing frame 1341 by the adhesive 1344. The stainless steel plate 1343 is installed on the top of the canopy steel beam 131. The fixing plate 1342 is disposed between the fixing frame 1341 and the stainless steel plate 1343. The bottom two ends of the fixing frame 1341 are fixed to the top of the stainless steel plate 1343. The fixing plate 1342 is disposed at the middle of the bottom end of the fixing frame 1341 and installed on the top of the stainless steel plate 1343. The adhesive 1344 includes silicone weather-resistant adhesive 1345 and double-sided adhesive 1346. Both silicone weather-resistant adhesive 1345 and double-sided adhesive 1346 are bonded between the top of the fixing frame 1341 and the glass canopy panel 132. Silicone weather-resistant adhesive 1345 is bonded to one side of the double-sided adhesive 1346. The glass canopy panel 132 is fixed to the top of the fixing frame 1341 by silicone weather-resistant adhesive 1345 and double-sided adhesive 1346.

[0050] Compared with the prior art, the technical solution disclosed in the above embodiments has the following beneficial effects:

[0051] In the above embodiments, the curtain wall lightning protection system 2 of the present invention uses conductive connecting pieces 24 to establish a lightning current path from the column 111 to the connecting conductor 22 in the area of ​​the glass curtain wall 11. The embedded part 21 is welded to the equipotential zone (foundation steel mesh) of the main building structure 3 to form an initial grounding point. The connecting conductor 22 is welded to the embedded part 21 and connected to the intermediate conductor 23 through the embedded part 21, so that the connecting conductor 22 and the column 111 form a conductive path. The conductive connecting pieces 24 are used to tightly connect the column 111, the intermediate conductor 23, and the connecting conductor 22 to ensure that all metal components of the glass curtain wall 11 form a uniform potential, avoiding backflash discharge caused by potential difference. When lightning strikes the surface of the glass curtain wall 11, At this time, the current is conducted through the column 111 to the conductive connecting piece 24, and then flows through the column 111 into the intermediate conductor 23 and the connecting conductor 22. Finally, it is introduced into the equipotential zone of the main building structure 3 through the embedded part 21 to achieve lightning discharge. This allows the lightning current to be quickly and safely introduced into the main building structure 3, avoiding the generation of high potential differences in local areas and protecting the safety of equipment and personnel inside the building structure. The lightning protection current path is formed between the conductive connecting piece 24, the intermediate conductor 23, the connecting conductor 22 and the main building structure 3. The multiple connection structure ensures the stability and reliability of the lightning protection current path. Even if a certain connection part becomes loose or corroded, the other connections can still ensure the conduction of current, effectively improving the lightning protection performance of the curtain wall.

[0052] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of this application. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
