Description

Technical Field

[0001] This utility model belongs to the field of building curtain wall technology, and in particular relates to a curtain wall keel structure. Background Technology

[0002] With the diversification of modern architectural design, curved curtain walls have gradually become the preferred choice for high-end buildings due to their unique visual effects and spatial expressiveness. However, the realization of curved curtain walls requires complex support structures, and traditional keel structures are mostly linear designs, which are difficult to adapt to the geometric changes of curved surfaces.

[0003] An existing patent (publication number CN106948530B) discloses a curtain wall keel connection structure, including vertical keels, with horizontal keels connected to one side or both sides of the vertical keels via connecting components. The horizontal keels are provided with transversely expanding grooves. The connecting components include connectors installed on the vertical keels. Each connector is provided with a connecting part that can be inserted into the transversely expanding groove from the opening of the transversely expanding groove for each horizontal keel. The connecting part is inserted into the transversely expanding groove of the horizontal keel and fixedly connected to the horizontal keel by a first fastening component.

[0004] Currently, the industry mainly uses customized processing or segmented splicing to install curved curtain walls. Customized keel processing is costly and time-consuming, and cannot adapt to design changes. Segmented splicing keel structures result in uneven curtain wall surfaces, affecting the building's appearance. Flexible material keels are not strong enough to meet the wind pressure and seismic load requirements of high-rise buildings. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a curtain wall keel structure with a hinge mechanism that allows the secondary keel to rotate freely within a certain range, ensuring the flat installation of the curtain wall panels. This solves the problems mentioned in the aforementioned comparative documents, such as the unevenness of the curtain wall surface caused by segmented splicing keel structures, which affects the building's appearance; and the insufficient strength of flexible material keels, which makes it difficult to meet the wind pressure and seismic load requirements of high-rise buildings.

[0006] To achieve the above objectives, this application provides the following technical solution: a curtain wall keel structure, including a main keel, flanges at both ends of the main keel, secondary keels at the top and bottom of the main keel, hinges welded to both sides of the secondary keels, fixing bolts threaded to the top of the hinges, the hinges and flanges fixedly connected by the fixing bolts, a second hinge welded to the outer surface of the main keel, and a horizontal keel fixedly connected to the outer surface of the main keel through the second hinge.

[0007] The above solution involves welding the hinge to the secondary keel. When installation is required, the flange is placed at the end of the main keel, and the bottom of the hinge is fitted against the flange. A fixing bolt is then used to connect the hinge to the flange through the threaded hole. This connects and fixes the secondary keel to the main keel. A second hinge connects to the horizontal keel on the outside of the main keel. The arc shape of the back of the second hinge matches the welding surface of the keel. The secondary keel is fixed to the main keel by adjusting its angle through the hinge, forming a stable support frame. The hinge mechanism allows the secondary keel to rotate freely within a certain range, ensuring the flat installation of the curtain wall panels.

[0008] Furthermore, both the main keel and the transverse keel are curved keels, and the secondary keel is a straight keel. The number of transverse keels and the main keel are both set in several groups, and the spacing between each pair of transverse keels is equal.

[0009] The above scheme adapts to the curved surface changes of the curtain wall by using the arc design of the main keel and the connection and support of the horizontal keels. Several sets of horizontal keels are connected to the main keel to form a wall frame that provides balanced support for the curtain wall. In particular, the service life is extended by applying an anti-corrosion coating to the surface of the secondary keel.

[0010] Furthermore, the hinge includes an upper hinge plate, a lower hinge plate is hinged to the bottom of the hinge plate, the lower hinge plate is fitted to the top of the flange, and the fixing bolt extends through the lower hinge plate into the interior of the flange and is threadedly connected to it.

[0011] The above solution involves welding the upper hinge plate to the secondary keel. When the secondary keel needs to be connected and installed with the main keel, the lower hinge plate allows the secondary keel to rotate flexibly at a certain angle, enabling it to rotate freely within a certain range to adapt to the curved connection point of the main keel and connect stably with it.

[0012] Furthermore, a torsion spring is welded to the top of the upper hinge plate. The torsion spring is in the shape of an inverted trapezoid, and both sides of the torsion spring are threaded with side fixing bolts.

[0013] The above solution involves welding a torsion spring to the top of the upper hinge plate so that it can be mounted on the top of the secondary keel. This allows the top of the secondary keel to have a certain elastic deformation space when connected to the wall connection component. When fixed with side bolts, it has the effect of compression and expansion of the connection space, making the installation more flexible.

[0014] Furthermore, the second hinge includes a second upper hinge plate, the back of which is curved, a fixed hinge plate is hinged to the bottom of the second upper hinge plate, and a second bolt is threaded to the top of the fixed hinge plate.

[0015] The above solution involves designing the back of the second upper hinge plate with an arc-shaped surface that matches the curve of the main keel. This allows the second upper hinge plate to be welded and fixed to the main keel, resulting in better stress resistance. Furthermore, the hinge plate, along with the second bolt, can be stably connected to the horizontal keel to form a stable curtain wall installation frame.

[0016] Furthermore, curved grooves are provided inside both the main keel and the transverse keel, and the curved grooves are located at the center of the main keel and the transverse keel, respectively.

[0017] The above scheme, through the setting of the curved groove, allows for the addition of reinforcing ribs on the inner side of the curved groove when necessary, in order to improve its bending stiffness and enhance its own support strength.

[0018] Furthermore, the second upper hinge plate and the fixed hinge plate are each provided in several groups, and the several groups of fixed hinge plates are symmetrically arranged on the outer surface of the horizontal keel.

[0019] The above scheme allows for the connection of the horizontal keel to the vertical main keel on both the upper and lower sides by symmetrically installing the second upper hinge plate and the fixed hinge plate, thereby increasing the connection strength and forming a more stable support frame.

[0020] Furthermore, the number of flanges is set to several.

[0021] The above scheme uses multiple sets of flanges installed at the top and bottom of the main keel to provide connecting bridge components for the secondary keel, enabling the secondary keel to be connected and installed with the main keel at multiple locations.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This curtain wall keel structure welds hinges to the secondary keel. When installation is required, a flange is placed at the end of the main keel, and the bottom of the hinge is fitted against the flange. A fixing bolt passes through the threaded hole of the hinge and connects to the flange, thus fixing the secondary keel to the main keel. A second hinge connects to the horizontal keel on the outside of the main keel. The arc shape of the back of the second hinge is the same as the welding surface of the keel. The secondary keel is fixed to the main keel by adjusting its angle through the hinge, forming a stable support frame. The hinge mechanism allows the secondary keel to rotate freely within a certain range, thus ensuring the flat installation of the curtain wall panels. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a curtain wall keel structure includes a main keel 1, with flanges 2 at both ends of the main keel 1. Secondary keels 3 are provided at the top and bottom of the main keel 1. Hinges 4 are welded to both sides of the secondary keels 3. A fixing bolt 5 is threaded onto the top of each hinge 4. The hinge 4 and the flanges 2 are fixedly connected by the fixing bolts 5. A second hinge 6 is welded to the outer surface of the main keel 1, and a horizontal keel 7 is fixedly connected to the outer surface of the main keel 1 via the second hinge 6. By welding the hinges 4 to the secondary keels 3, when installation is required, the flanges 2 are placed at the ends of the main keels 1. The hinge 4 is fitted with the bottom of the flange 2, and the hinge 4 is connected to the flange 2 by the threaded hole of the hinge 4 through the fixing bolt 5. In this way, the secondary keel 3 can be connected and fixed to the main keel 1. The second hinge 6 is connected to the horizontal keel 7 on the outside of the main keel 1. The arc shape of the back of the second hinge 6 is the same as the arc shape of the welding surface of the main keel 1. The secondary keel 3 is fixed to the main keel 1 by adjusting the angle through the hinge 4 to form a stable support frame. The hinge mechanism of the hinge 4 allows the secondary keel 3 to rotate freely within a certain range, thereby ensuring the flat installation of the curtain wall panel.

[0027] Please see Figure 2 and Figure 4The hinge 4 includes an upper hinge plate 401, with a lower hinge plate 402 hinged to the bottom of the hinge plate 401. The lower hinge plate 402 is attached to the top of the flange 2. The fixing bolt 5 passes through the lower hinge plate 402 and extends into the interior of the flange 2 and is threadedly connected to it. When the upper hinge plate 401 is welded to the secondary keel 3, the secondary keel 3 can be flexibly rotated at a certain angle when it is necessary to connect and install the secondary keel 3 to the main keel 1. This allows the secondary keel 3 to rotate freely within a certain range to adapt to the curved connection of the main keel 1 and to be stably connected to it.

[0028] Please refer to 4. A torsion spring 403 is welded to the top of the upper hinge plate 401. The torsion spring 403 is in the shape of an inverted trapezoid, and both sides of the torsion spring 403 are threaded with side fixing bolts 404. By welding the torsion spring 403 to the top of the upper hinge plate 401, it is mounted on the top of the secondary keel 3. When the top of the secondary keel 3 is connected to the wall connection component, there is a certain elastic deformation space. When it is fixed with the side fixing bolts 404, it has the effect of compression and expansion of the connection space, making it more flexible during installation.

[0029] Please see Figure 2 and Figure 5 The second hinge member 6 includes a second upper hinge plate 601. The back of the second upper hinge plate 601 is curved. A fixed hinge plate 602 is hinged to the bottom of the second upper hinge plate 601. A second bolt 603 is threaded to the top of the fixed hinge plate 602. By designing the back of the second upper hinge plate 601 to be curved in the same way as the main keel 1, the second upper hinge plate 601 can be welded and fixed to the main keel 1 with better stress resistance. In addition, the fixed hinge plate 602 and the second bolt 603 can be stably connected to the horizontal keel 7 to form a stable curtain wall installation frame.

[0030] In this embodiment, a curtain wall keel structure is provided. A torsion spring 403 is welded to the top of the upper hinge plate 401, which is then mounted on the top of the secondary keel 3. This allows the secondary keel 3 to have a certain elastic deformation space when connected to the wall connection components. When fixed with the side bolts 404, this provides a compression and expansion effect on the connection space, making installation more flexible. By welding the upper hinge plate 401 to the secondary keel 3, when the secondary keel 3 needs to be connected to the main keel 1, the lower hinge plate 402 allows the secondary keel 3 to rotate flexibly to a certain extent. The angle effect allows the secondary keel 3 to rotate freely within a certain range to adapt to the connection of the curved main keel 1 and to connect stably with it. By designing the back of the second upper hinge plate 601 to be an arc surface consistent with the curve of the main keel 1, the stress resistance effect of the second upper hinge plate 601 after welding and fixing to the main keel 1 is better. In addition, it can be stably connected to the horizontal keel 7 with the fixed hinge plate 602 and the second bolt 603. With the setting of the curved groove 8, a reinforcing rib can be added to the inner side of the curved groove 8 when necessary to improve its bending stiffness and enhance its own support strength.

[0031] It should be noted that...

[0032] The working principle of the above embodiments is as follows: The upper hinge plate 401 is welded to the secondary keel 3. When the secondary keel 3 needs to be connected and installed to the main keel 1, the secondary keel 3 is rotated at a certain angle by the lower hinge plate 402 to match the angle of the connection end of the main keel 1. The fixing bolt 5 passes through the threaded hole of the lower hinge plate 402 and is connected to the flange 2 to connect and fix the secondary keel 3 to the main keel 1. A torsion spring plate 403 is welded to the top of the upper hinge plate 401 so that it is fitted on the top of the secondary keel 3. When the top of the secondary keel 3 is connected to the wall connection component, the torsion spring plate 403 generates elastic deformation to adapt to the specifications of the connection component. The torsion spring plate 403 is connected to the top component of the wall by the side fixing bolt 404. The back of the second upper hinge plate 601 is designed with an arc surface that matches the curve of the main keel 1. The second bolt 603 passes through and fixes the hinge plate 602 to the main keel 1 so that the horizontal keel 7 and the main keel 1 cooperate to form a stable connection frame.
