Description

Technical Field

[0001] This utility model relates to the field of curtain wall keel technology, and in particular to a curtain wall keel installation and fixing device with adaptive adjustment function. Background Technology

[0002] The curtain wall keel installation and fixing device with adaptive adjustment function is mainly used in building curtain wall projects to accurately install and fix the keel (vertical and horizontal skeleton) supporting the curtain wall panel, ensuring the stability of the curtain wall structure and the flatness of the surface. At the same time, it can adapt to the construction deviation of the main building and environmental changes (such as temperature deformation). It is widely used in curtain wall construction scenarios of various buildings such as office buildings, shopping malls, stadiums, and airports, and is a core device to ensure the safety and aesthetics of the curtain wall.

[0003] Currently, various equipment, methods, and approaches are used to achieve the installation and fixing function of curtain wall keel: some projects use rigid fixing connectors (such as directly welded angle brackets), which fix the keel to the embedded parts by welding. During installation, precise manual alignment is required, and if the deviation is too large, cutting or welding is required; some scenarios use adjustment components with simple long holes, which connect the keel to the embedded parts by bolts passing through the long holes. During adjustment, the bolts are loosened and the keel is manually pushed, and then tightened to fix it in place; there is also a connection method using ordinary flat washers, in which the horizontal and vertical keels are rigidly connected by bolts. During installation, the angle must be strictly controlled, and if there is a deviation, it must be forcibly bent and adjusted.

[0004] However, the above method has a significant drawback: ordinary flat washers are planar annular structures with flat surfaces on both the top and bottom. When the horizontal keel is connected to the vertical keel by bolts, the flat washer can only achieve axial compression and cannot produce radial angular deflection. For curved curtain walls or horizontal keels that need to be installed at an angle, the connection angle between the horizontal and vertical keels needs to change synchronously with the curvature of the curtain wall. However, the rigid planar contact of ordinary flat washers will forcibly restrict this angle change, resulting in a hard contact at the connection point between the horizontal and vertical keels. If installed at the angle allowed by the flat washer, the horizontal keel cannot conform to the design trajectory of the curved curtain wall, ultimately leading to gaps between the keel and the panel. This not only affects the sealing performance of the curtain wall but also exacerbates panel wear due to uneven stress. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a curtain wall keel installation and fixing device with adaptive adjustment function. It solves the problem that ordinary flat washers, being planar annular structures with flat surfaces on both the top and bottom, can only achieve axial compression when horizontal keels are connected to vertical keels via bolts, failing to produce radial angular deflection. For curved curtain walls or horizontal keels requiring inclined installation, the connection angle between the horizontal and vertical keels needs to change synchronously with the curvature of the curtain wall. However, the rigid planar contact of ordinary flat washers forcibly restricts this angle change, resulting in hard contact at the connection points of the horizontal and vertical keels. If installed at the angle allowed by the flat washer, the horizontal keel cannot conform to the design trajectory of the curved curtain wall, ultimately leading to gaps between the keel and the panel. This not only affects the curtain wall's sealing performance but also exacerbates panel wear due to uneven stress.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A curtain wall keel installation and fixing device with adaptive adjustment function includes embedded parts, adapters, vertical keels and horizontal keels. The embedded parts are fixed to the main building structure. A horizontal adjustment mechanism is provided between the adapter and the embedded parts. A vertical adjustment mechanism is provided between the vertical keel and the adapter. The two ends of the horizontal keel are respectively connected to the vertical keel through angle adjustment mechanisms. The horizontal adjustment mechanism includes an elongated hole and an adjusting bolt. The elongated hole is opened on the surface of the adapter. The adjusting bolt passes through the elongated hole and is threadedly connected to the embedded part. The vertical adjustment mechanism includes a waist-shaped groove and a fastening bolt. The waist-shaped groove is opened vertically on the side wall of the vertical keel. The fastening bolt passes through the waist-shaped groove and is fixed to the adapter.

[0008] Preferably, the angle adjustment mechanism includes a connecting angle bracket and a spherical washer. One end of the connecting angle bracket is welded to the horizontal keel, and the other end is bolted to the vertical keel through the spherical washer.

[0009] Preferably, an elastic buffer pad is provided between the adapter and the embedded part, and the elastic buffer pad is made of rubber.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The vertical keel can slide vertically along the waist-shaped groove with an adjustment range of ±5 mm to correct the elevation deviation of the keel and ensure that the keel height is consistent in the same layer. The horizontal keel is connected to the vertical keel through connecting angle brackets. The spherical washer allows the connecting angle bracket to rotate slightly around the bolt with an adjustment range of ±2 degrees to adapt to the curvature changes of the curtain wall surface or the tilt requirements of the horizontal keel, ensuring the fit between the keel and the panel. The elastic buffer pad between the adapter and the embedded part can absorb the stress generated by temperature deformation or vibration, avoid cracking or loosening of the keel due to rigid connection, and improve the durability of the device.

[0018] The proposed curtain wall keel installation and fixing device solves the problem that ordinary flat washer connections cannot achieve angle adjustment. Its horizontal keel is connected to the vertical keel through connecting angle brackets, and with the help of spherical washers, it can achieve a fine adjustment of ±2 degrees of angle, which can adapt to the needs of curved curtain walls or inclined keels, ensuring that the keel fits the panel and avoids gaps and panel wear. At the same time, the vertical keel can be adjusted by ±5 mm of vertical adjustment with the help of the waist-shaped groove, correcting the elevation deviation to ensure that the height of the same floor is consistent. The elastic buffer pad between the adapter and the embedded part can also absorb temperature deformation or vibration stress, prevent the keel from cracking and loosening, and improve durability. Example

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that ordinary flat washers are planar annular structures with flat surfaces on both the upper and lower surfaces. When the horizontal keel is connected to the vertical keel by bolts, the flat washer can only achieve axial compression and cannot produce radial angular deflection. For curved curtain walls or horizontal keels that require inclined installation, the connection angle between the horizontal and vertical keels needs to change synchronously with the curvature of the curtain wall. However, the rigid flat contact of ordinary flat washers will forcibly restrict this angle change, resulting in a hard contact at the connection point between the horizontal and vertical keels. If installed at the angle allowed by the flat washers, the horizontal keel cannot conform to the design trajectory of the curved curtain wall, ultimately leading to gaps between the keel and the panel. This not only affects the curtain wall's sealing performance but also exacerbates panel wear due to uneven stress. The overall approach is as follows: a curtain wall keel installation and fixing device with adaptive adjustment function, including embedded part 1, adapter 2, vertical keel 3, and horizontal keel 4. Embedded part 1 is fixed to the main building structure. A horizontal adjustment mechanism is provided between adapter 2 and embedded part 1. A vertical adjustment mechanism is provided between vertical keel 3 and adapter 2. The horizontal keel 4 is connected to the vertical keel 3 at both ends through angle adjustment mechanisms. The horizontal adjustment mechanism includes an elongated hole 21 and an adjusting bolt 22. The elongated hole 21 is opened on the surface of the adapter 2. The adjusting bolt 22 passes through the elongated hole 21 and is threadedly connected to the embedded part 1. The vertical adjustment mechanism includes a waist-shaped groove 31 and a fastening bolt 32. The waist-shaped groove 31 is opened vertically on the side wall of the vertical keel 3. The fastening bolt 32 passes through the waist-shaped groove 31 and is fixed to the adapter 2. The adapter 2 is connected to the embedded part 1 through the elongated hole 21. After loosening the adjusting bolt 22, the adapter 2 can slide horizontally along the elongated hole 21 within a range of ±10 mm to achieve horizontal position compensation of the keel and adapt to the construction deviation of the main structure. After adjustment, the adjusting bolt 22 is tightened to fix it. The vertical keel 3 is connected to the adapter 2 through the waist-shaped groove 31.

[0020] The angle adjustment mechanism includes a connecting angle bracket 41 and a spherical washer 42. One end of the connecting angle bracket 41 is welded to the horizontal keel 4, and the other end is bolted to the vertical keel 3 through the spherical washer 42. After loosening the fastening bolt 32, the vertical keel 3 can slide vertically along the waist groove 31 within a range of ±5 mm to adjust the keel's elevation deviation and ensure that the keels in the same layer are of consistent height. The horizontal keel 4 is connected to the vertical keel 3 through the connecting angle bracket 41. The spherical washer 42 allows the connecting angle bracket 41 to rotate slightly around the bolt within a range of ±2 degrees to adjust the angle, adapting to the curvature changes of the curtain wall surface or the tilt requirements of the horizontal keel 4, and ensuring the fit between the keel and the panel.

[0021] An elastic buffer pad 5 is also provided between the adapter 2 and the embedded part 1. The elastic buffer pad 5 is made of rubber. The elastic buffer pad 5 between the adapter 2 and the embedded part 1 can absorb the stress generated by temperature deformation or vibration, avoid cracking or loosening of the keel due to rigid connection, and improve the durability of the device.

[0022] To address the problems existing in the prior art, this utility model provides a curtain wall keel installation and fixing device with adaptive adjustment function. The vertical keel 3 can slide vertically along the waist groove 31 with an adjustment range of ±5 mm to correct the elevation deviation of the keel and ensure that the height of the keel in the same layer is consistent. The horizontal keel 4 is connected to the vertical keel 3 through the connecting angle bracket 41. The spherical washer 42 allows the connecting angle bracket 41 to rotate slightly around the bolt with an adjustment range of ±2 degrees to adapt to the curvature change of the curtain wall surface or the tilting requirements of the horizontal keel 4, ensuring the fit between the keel and the panel. The elastic buffer pad 5 between the adapter 2 and the embedded part 1 can absorb the stress generated by temperature deformation or vibration, avoid cracking or loosening of the keel due to rigid connection, and improve the durability of the device.

[0023] Working principle:

[0024] First, the adapter 2 is connected to the embedded part 1 through the elongated hole 21. After loosening the adjusting bolt 22, the adapter 2 can slide horizontally along the elongated hole 21 within a range of ±10 mm to achieve horizontal position compensation of the keel and adapt to the construction deviation of the main structure. After adjustment, tighten the adjusting bolt 22 to fix it. The vertical keel 3 is connected to the adapter 2 through the waist groove 31.

[0025] In the second step, after loosening the fastening bolts 32, the vertical keel 3 can slide vertically along the waist groove 31 within a range of ±5 mm to adjust the keel's elevation deviation and ensure that the keels in the same layer are of consistent height. The horizontal keel 4 is connected to the vertical keel 3 through the connecting bracket 41. The spherical washer 42 allows the connecting bracket 41 to rotate slightly around the bolt within a range of ±2 degrees to adjust the angle, adapting to the curvature changes of the curtain wall surface or the tilt requirements of the horizontal keel 4, ensuring the fit between the keel and the panel. The elastic buffer pad 5 between the adapter 2 and the embedded part 1 can absorb the stress generated by temperature deformation or vibration, preventing the keel from cracking or loosening due to rigid connection, and improving the durability of the device.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
