Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a curved curtain wall for building facades. Background Technology

[0002] Curved facade curtain walls, as a non-load-bearing external envelope system composed of metal components and three-dimensional curved panels, play an important role in the construction field. With the development of various new public buildings, building facade shapes have become more varied and building forms have become more complex, leading to a significant increase in the demand for full-length curtain walls.

[0003] In the past, the irregularity of curved curtain walls on building facades has led to complicated procedures, unstable stress points on the curved surface, and difficulty in ensuring the overall stability of the curtain wall, making it difficult to efficiently meet construction requirements. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a curved curtain wall for building facades.

[0005] The technical solution for a curved curtain wall for building facades provided in this application is as follows: A curved curtain wall for building facade includes a fixed base, metal keel, and curtain wall glass; the fixed base is divided into a bottom base and a top base, the bottom base is installed on the building's horizontal reference plane, and the top base is installed on the building wall; several metal keels are provided, each metal keel is bent to form a curved shape, and the bending position of each metal keel is different, one end of the metal keel is connected to the bottom base, and the other end is connected to the top base, and stabilizing components are provided between adjacent metal keels; the curtain wall glass is installed on the inner side of the metal keel.

[0006] By adopting the above technical solution, the metal keel is bent into a curved shape at different locations, which can meet the shaping of the curved surface of the building facade. The metal keel is fixed to the main structure of the building through the bottom base and the top base, which can ensure the overall stability of the curtain wall installation. Stable components are set between adjacent metal keels. Since the metal keels with different bending shapes have different stress points under different bending degrees, the stable components connect the adjacent metal keels, thereby distributing the stress and further enhancing the overall stability of the curtain wall. The curtain wall glass is installed on the inside of the metal keel, which can meet the building maintenance requirements.

[0007] Optionally, the stabilizing components include stabilizing bolts, stabilizing nuts, and stabilizing sleeves; through holes are provided on the metal keel; stabilizing bolts pass through the through holes, and stabilizing bolts on adjacent metal keels are arranged opposite each other, with a gap between the stabilizing bolts; stabilizing nuts are screwed onto one end of the stabilizing bolts; a stabilizing sleeve is screwed onto any one of the stabilizing bolts, and after the stabilizing bolt is inserted into the through hole, the stabilizing sleeve is rotated to connect the stabilizing sleeve between the two stabilizing bolts.

[0008] By adopting the above technical solutions, the stabilizing components utilize structures such as stabilizing bolts, stabilizing nuts, and stabilizing sleeves to adapt to metal keels with different intervals and enhance the connection stability between adjacent metal keels, making the curved curtain wall structure of the building facade more stable. At the same time, the connection method of bolts and sleeves facilitates installation and disassembly, improving construction efficiency.

[0009] Optionally, the through hole is divided into a first through hole and a second through hole, and the first through hole and the second through hole are arranged alternately; a stabilizing component is provided in both the first through hole and the second through hole.

[0010] By adopting the above technical solution, stabilizing components are set in both the first and second through holes, so that the staggered stabilizing components will not interfere with each other, thereby improving the compatibility of the connection between adjacent metal keels.

[0011] Optionally, both the first and second through holes can be elongated.

[0012] By adopting the above technical solution, the elongated holes can be adapted to the positions of the holes between the metal keels, thereby improving the connection adaptability of the curved metal keels.

[0013] Optionally, the outer surface of the stabilizing sleeve is provided with anti-slip texture.

[0014] By adopting the above technical solution, the anti-slip texture can increase the friction with the human body, allowing workers to rotate the stabilizing sleeve more stably and ensuring the comfort of using the stabilizing sleeve.

[0015] Optionally, the stabilizing component also includes an arc-shaped block connected to a stabilizing bolt; the arc-shaped block is provided with an annular groove, and a sliding block is slidably connected in the annular groove; the sliding block is connected to an extension bolt, and two opposing extension bolts are screwed together by a stabilizing sleeve.

[0016] By adopting the above technical solution, the stabilizing sleeve is connected between the two extension bolts, and the extension bolts can slide along the annular groove through the sliding block, thereby adjusting the extension position of the extension bolts. This method is mainly to adapt to the curvature or bending degree of the metal keel and further improve the adaptability of the connection when stabilizing the metal keel.

[0017] Optionally, the arc-shaped block has a threaded groove on the side near the metal keel and is screwed to a stabilizing bolt through a threaded hole.

[0018] By adopting the above technical solution, the arc-shaped block rotates along the threaded groove of the stabilizing bolt, and the annular slide groove rotates accordingly at a certain angle, thereby adjusting the angle of the sliding block or extension bolt. This method not only facilitates assembly, but also further provides angular adaptability.

[0019] Optionally, the sliding block has a threaded hole, and the extension bolt is screwed to the sliding block through the threaded hole.

[0020] By adopting the above technical solution, the extension bolt and sliding block are screwed together, which can facilitate assembly and maintenance, and extend the service life of the building.

[0021] Optionally, the sliding block has a socket, and a fixing pin is inserted into the socket, with the fixing pin passing through the socket and connecting to the arc-shaped block.

[0022] By adopting the above technical solution, after the position of the sliding block is determined, the fixing nail is driven into the arc-shaped block through the insertion hole, which can prevent the sliding block from sliding randomly in the annular groove and ensure the stability of the connection.

[0023] Optionally, reinforcing ribs are provided at the connection point between the fixed base and the metal keel.

[0024] By adopting the above technical solutions, the metal keel can be reinforced with reinforcing ribs when under stress, thereby improving the safety and stability of the metal keel during use.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The metal keel is bent into a curved shape at different locations, which can meet the shaping of the curved surface of the building facade. The metal keel is fixed to the main structure of the building through the bottom base and the top base, which can ensure the overall stability of the curtain wall installation. Stable components are set between adjacent metal keels. Since the metal keels with different bending shapes have different stress points under different bending degrees, the stable components connect the adjacent metal keels, thereby distributing the stress and further enhancing the overall stability of the curtain wall. The curtain wall glass is installed on the inside of the metal keel, which can meet the building maintenance requirements. 2. The stabilizing components utilize stabilizing bolts, stabilizing nuts, and stabilizing sleeves to adapt to metal keels with different spacing and enhance the connection stability between adjacent metal keels, making the curved curtain wall structure of the building facade more stable.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0033] This application discloses a curved curtain wall for building facades.

[0034] A curved curtain wall for building facade, reference Figure 1 As shown, the structure includes a fixed base 1, a metal keel 2, and curtain wall glass 3. The fixed base 1 is divided into a bottom base 12 and a top base 11. The bottom base 12 is installed on the building's horizontal reference plane, such as the ground or a building platform. The top base 11 is installed on the building wall. In addition to the building wall, it can also be installed on other platforms of the building, such as terraces or load-bearing platforms extending from the building. One end of the metal keel 2 is connected to the bottom base 12, and the other end is connected to the top base 11. In this way, the metal keel 2 is stably fixed to the main structure of the building, which can withstand the weight of the curtain wall and the action of external forces, ensuring the stability of the curtain wall. The connection method of the metal keel 2 can be welding or other connection methods.

[0035] Several metal keels 2 are provided, each consisting of a load-bearing square tube and a fixed wing plate. The metal material is preferably stainless steel pipe. Each metal keel 2 is bent, forming a curved shape, and the bending position of each metal keel 2 is different, which can achieve different building facade shapes. Due to the different bending shapes of the metal keels 2, the stress points of the overall metal keel 2 are also different when the bending degree is different. If some metal keels 2 bend too much, the entire keel will tilt in the bending direction. Therefore, a stabilizing component 4 is set between adjacent metal keels 2. The stabilizing component 4 connects adjacent metal keels 2. When one metal keel 2 is subjected to excessive force, the force can be transferred to the adjacent metal keels 2 through the stabilizing component 4. After the adjacent metal keels 2 disperse the force, they can then transfer the force to other metal keels 2. In this way, the stabilizing component 4 achieves the function of distributing the force, which can further enhance the overall stability of the curtain wall.

[0036] The curtain wall glass 3 is installed inside the metal keel 2. Because the metal keel 2 is bent and has a curved shape, the curtain wall glass 3 can be cut into suitable sizes in the factory according to the curved shape of the metal keel 2 to match the bending degree of the metal keel 2. After being installed inside the metal keel 2, the curtain wall glass 3 can be connected by aluminum alloy connectors and then fastened with bolts. After installation, it can play a role in maintaining the interior space of the building, preventing wind and rain, and providing heat insulation.

[0037] Specifically, the metal keel 2 is bent into a curved shape at different locations to meet the requirements of shaping the curved surface of the building facade. The metal keel 2 is fixed to the main structure of the building through the bottom base 12 and the top base 11, which can ensure the overall stability of the curtain wall installation. Stable components 4 are set between adjacent metal keels 2. Since the metal keels 2 with different curved shapes have different stress points under different bending degrees, the stable components 4 connect the adjacent metal keels 2 to distribute the stress, which can further enhance the overall stability of the curtain wall. The curtain wall glass 3 is installed on the inside of the metal keel 2 to meet the building maintenance requirements.

[0038] Further reference Figure 3As shown, the stabilizing component 4 includes a stabilizing bolt 41, a stabilizing nut 42, and a stabilizing sleeve 43. A through hole is provided on the metal keel 2, through which the stabilizing bolt 41 passes. The stabilizing bolts 41 on adjacent metal keels 2 are arranged opposite each other, and there is a gap between the stabilizing bolts 41. The purpose of using two sets of stabilizing bolts 41 on adjacent metal keels 2 is to adapt to the gap between adjacent metal keels 2. That is, if the gap between adjacent metal keels 2 is too large, a longer stabilizing bolt 41 can be replaced. However, if the stabilizing bolt 41 is still not long enough, two sets of adjacent stabilizing bolts 41 are used to pass through the through hole on the metal keel 2, and the two sets of adjacent stabilizing bolts 41 extend relative to each other, thereby shortening the gap between the two sets of stabilizing bolts 41.

[0039] The stabilizing nut 42 is screwed onto one end of the stabilizing bolt 41, and the stabilizing bolt 41 is locked in place to prevent the stabilizing bolt 41 from coming out of the through hole.

[0040] A stabilizing sleeve 43 is screwed onto any one of the stabilizing bolts 41. The inner wall of the stabilizing sleeve 43 has an internal thread. After the stabilizing bolt 41 is inserted into the through hole, the stabilizing sleeve 43 is rotated into the stabilizing bolt 41 by screwing. Another stabilizing bolt 41 is inserted into the through hole of the adjacent metal keel 2. After both sets of stabilizing bolts 41 are fixed by stabilizing nuts 42, the stabilizing sleeve 43 is rotated so that it is unscrewed from one of the stabilizing bolts 41 and screwed into the other stabilizing bolt 41. This allows the two ends of the stabilizing sleeve 43 to be connected to the two stabilizing bolts 41 respectively, forming a bridging function. This can accommodate the spacing between different metal keels 2. When the adjacent metal keel 2 is under force, the force is transmitted to the stabilizing sleeve 43 through the stabilizing bolt 41, and then to the other stabilizing bolt 41 through the stabilizing sleeve 43, thereby transmitting the force to the adjacent metal keel 2 and achieving the effect of distributing the force.

[0041] Furthermore, refer to Figure 1 As shown, the through holes are divided into a first through hole 21 and a second through hole 22, and the first through hole 21 and the second through hole 22 are staggered. Since there are adjacent metal keels 2 on both sides of the middle metal keel 2, the two adjacent metal keels 2 cannot be connected on the same plane. Therefore, two through holes, the first through hole 21 and the second through hole 22, are opened on the metal keel 2 to connect the two adjacent metal keels 2 respectively. Since the positions of the first through hole 21 and the second through hole 22 of the adjacent metal keels 2 are the same and they are opened opposite each other, the stabilizing components 4 are set in the first through hole 21 and the second through hole 22, so that the staggered stabilizing components 4 will not interfere with each other, and improve the compatibility of the connection between the adjacent metal keels 2.

[0042] Furthermore, refer to Figure 3As shown, both the first through hole 21 and the second through hole 22 are elongated holes. The elongated holes allow the stabilizing component 4 to move along the elongated holes, so that the positions of the first through hole 21 or the second through hole 22 between two adjacent metal keels 2 are different due to different degrees of bending or curvature. Therefore, the elongated holes can be adapted to the hole positions between the metal keels 2 to improve the connection adaptability of the bent metal keels 2.

[0043] Further, refer to Figure 3 As shown, the outer surface of the stabilizing sleeve 43 is provided with anti-slip texture. The anti-slip texture can increase the friction with the human body, allowing the worker to rotate the stabilizing sleeve 43 more stably and ensuring the comfort of using the stabilizing sleeve 43.

[0044] In some embodiments, reference Figure 4 As shown, the stabilizing component 4 also includes an arc-shaped block 44, which is connected to the stabilizing bolt 41. The arc-shaped block 44 is provided with an annular groove 441, and a sliding block 45 is slidably connected in the annular groove 441. The sliding block 45 can slide along the annular groove 441 to adapt to the curvature or bending degree of the metal keel 2.

[0045] The annular groove 441 can have a T-shaped cross section. The sliding block 45 is adapted to the annular groove 441 and its cross section is also T-shaped to ensure the limiting effect and prevent the sliding block 45 from leaving the annular groove 441. The side of the sliding block 45 near the arc block 44 is an arc surface to ensure the smooth sliding of the sliding block 45.

[0046] The sliding block 45 is connected to the extension bolt 46. The two opposite extension bolts 46 are screwed together by the stabilizing sleeve 43. The extension bolt 46 replaces the original fixing bolt, so that the stabilizing sleeve 43 is connected between the two extension bolts 46. The extension bolt 46 can slide along the annular groove 441 through the sliding block 45, thereby adjusting the extension position of the extension bolt 46. This method is mainly to adapt to the curvature of the metal keel 2 or the horizontal position of the through hole opening, and further improve the adaptability of the connection when stabilizing the metal keel 2.

[0047] Among them, reference Figure 4 or Figure 5As shown, the arc-shaped block 44 has a threaded groove 442 on the side near the metal keel 2, and is screwed to the fixing bolt 41 through the threaded groove 442. The way the arc-shaped block 44 is screwed through the threaded groove 442 not only facilitates the assembly of the arc-shaped block 44, but also adapts to rotation at different angles. For example, the annular slide groove 441 on the arc-shaped block 44 is originally set horizontally. When the arc-shaped block 44 rotates along the threaded hole of the fixing bolt 41, the annular slide groove 441 will rotate from the horizontal state to a certain angle, thereby adjusting the angle of the sliding block 45 or the extension bolt 46. This method not only facilitates assembly, but also further provides angular adaptability.

[0048] Among them, reference Figure 5 As shown, the sliding block 45 has a threaded hole, and the extension bolt 46 is screwed to the sliding block 45 through the threaded hole. The screwing of the extension bolt 46 to the sliding block 45 allows for easy disassembly and replacement of the extension bolt 46. If the extension bolt 46 is corroded or oxidized due to prolonged exposure to rainwater, it will affect the stability of the overall connection. In this case, the bridging state of the two extension bolts 46 can be disengaged by rotating the stabilizing sleeve 43, and then the extension bolt 46 can be unscrewed from the sliding block 45 and replaced with a new extension bolt 46. This achieves the functions of convenient assembly and maintenance, and extends the service life of the building.

[0049] Further reference Figure 5 As shown, the sliding block 45 has an insertion hole, into which a fixing nail 47 is inserted. The fixing nail 47 passes through the insertion hole and connects to the arc-shaped block 44. The sliding block 45 is made of solid material, and the outer surface can be made of metal to ensure the stability of the connection. The solid filling material between the annular groove 441 and the threaded groove 442 can be plastic. The specific plastic material can be determined according to factors such as budget and fire protection requirements. After the plastic is filled, the fixing nail 47 passes through the insertion hole and is screwed or nailed into the arc-shaped block 44 using a hammer or screwdriver. Thus, after the position of the sliding block 45 is determined, nailing the fixing nail 47 through the insertion hole into the arc-shaped block 44 can prevent the sliding block 45 from sliding freely in the annular groove 441 and ensure the stability of the connection.

[0050] The number of holes in a single sliding block 45 is the same as the number of fixing pins 47, with at least two in each case, to improve the stability of the fixing effect of the sliding block 45.

[0051] In some embodiments, reference Figure 1 As shown, a reinforcing rib 13 is provided at the connection point between the fixed base 1 and the metal keel 2. The reinforcing rib 13 can adopt a triangular metal structure. The reinforcing rib 13 can enhance the strength of the connection point, disperse stress, and improve the overall stability of the curtain wall. When the metal keel 2 is under stress, the connection can be strengthened by the reinforcing rib 13, thereby improving the safety and stability of the metal keel 2 during use.

[0052] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
