A stable curtain wall frame

Abstract

This utility model discloses a stable curtain wall frame, relating to the field of building curtain wall technology. It includes two main load-bearing columns (I), each with a second main load-bearing column installed at its lower end via connectors. This utility model utilizes a fixing mechanism on the horizontal beam and a base on the underside of the curtain wall panel. The support of the fixing mechanism forms an elastic fit with the locking interfaces on both sides of the base through elastic ribs, achieving initial positioning of the curtain wall panel and the horizontal beam. Based on this, the annular strip clamp of the locking mechanism applies a circumferential tightening force to the elastic ribs through the cooperation of the buckle and the positioning hole, ensuring the elastic ribs remain tightly fitted to the inner wall of the locking interface, forming a reliable mechanical lock. This double-fixing structure not only effectively resists displacement under dynamic loads such as wind and earthquakes but also absorbs some energy through the deformation capacity of the elastic ribs, significantly improving the seismic performance of the curtain wall system.

Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically a stable curtain wall frame. Background Technology

[0002] The curtain wall frame is the supporting structural system that constitutes the building curtain wall. It is mainly composed of columns, beams and other components assembled with connectors. Its function is to fix the panels, such as glass, stone, metal plates, etc., and to transfer the load to the main structure. At the same time, it determines the overall shape and rigidity of the curtain wall. The frame materials are mostly aluminum alloy profiles, steel or stainless steel, and must have high strength, corrosion resistance and good wind pressure and seismic performance. Common structural forms include exposed frame, concealed frame, semi-concealed frame, etc., which are widely used in the facade decoration and enclosure of modern high-rise buildings. When installing the curtain wall, the position is usually measured and marked first, then the embedded parts are installed, then the keel is installed to form a supporting frame, and then the curtain wall panels are installed.

[0003] In existing technology, grooves are usually cut on the inner side of the secondary keel, and the curtain wall panels are slid into the grooves before subsequent installation. However, during installation, in order to facilitate installation, some distance is usually left between the groove and the curtain wall panel. In windy weather, the curtain wall panel is prone to swaying in the groove of the curtain wall frame and colliding with the curtain wall frame, resulting in problems such as curtain wall panel breakage. Therefore, a stable curtain wall frame is needed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a stable curtain wall frame, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable curtain wall frame, comprising two main load-bearing columns (first type), with a second main load-bearing column (second type) installed at the lower end of each of the two main load-bearing columns via a connector. The first and second main load-bearing columns are respectively fitted onto both ends of the connector. A horizontal beam is installed between the two first main load-bearing columns and between the two second main load-bearing columns. A curtain wall panel is provided between the two horizontal beams. A transverse mounting groove that mates with the curtain wall panel is provided on the horizontal beam. Several fixing mechanisms are provided on both sides of the transverse mounting groove on the upper surface of the horizontal beam. The fixing mechanisms are used to reinforce the curtain wall panel.

[0006] The fixing mechanism includes a support base fixedly connected to the upper surface of the crossbeam. Several elastic ribs distributed in a ring are fixedly connected to the upper surface of the support base. The elastic ribs are L-shaped. A fixing rod is fixedly connected to the middle of the upper surface of the support base. A conical top is provided at the top of the fixing rod. A locking mechanism is provided outside the elastic ribs. The locking mechanism is used to tighten the elastic ribs.

[0007] The locking mechanism includes an annular strip clamp sleeved on the outside of several elastic ribs. Several positioning holes are opened on the surface of the strip clamp. A lock head is fixedly connected to one end of the strip clamp. The other end of the strip clamp passes through the lock head and extends outward. A buckle is rotatably connected to the fixed end of the strip clamp.

[0008] The lower end of the curtain wall panel is fixedly connected to a base, the lower side of the base is engaged with a horizontal mounting groove, the upper middle part of the base is provided with a fixing groove for fixing the curtain wall panel, and several locking interfaces are provided on both sides of the base, which are engaged with the fixing mechanism.

[0009] The main load-bearing column one and the main load-bearing column two are assembled by a connector, and the two are respectively sleeved on both ends of the connector, and the adjacent end faces of the main load-bearing column one and the main load-bearing column two are tightly fitted together.

[0010] Vertical mounting slots are provided on the inner sides of the two main load-bearing columns and the two main load-bearing columns. The vertical mounting slots are used to engage with the two sides of the curtain wall panel. Connecting blocks are fixedly installed on the inner sides of the two main load-bearing columns and the two main load-bearing columns. Both ends of the crossbeam are engaged with the connecting blocks.

[0011] Auxiliary fasteners are provided on the outer sides of the two main load-bearing columns and the two main load-bearing columns, respectively, and the auxiliary fasteners are used to fix the curtain wall frame to the wall.

[0012] The two main load-bearing columns and the two main load-bearing columns are all connected to the auxiliary fixing parts by L-shaped connecting pieces.

[0013] This utility model provides a stable curtain wall frame, which has the following beneficial effects:

[0014] 1. This utility model, by configuring a fixing mechanism on the horizontal beam and setting a base on the lower side of the curtain wall panel, achieves the initial positioning of the curtain wall panel and the horizontal beam through the elastic ribs and the locking interfaces on both sides of the base. On this basis, the annular strip clamp of the locking mechanism can apply circumferential tightening force to the elastic ribs through the cooperation of the buckle and the positioning hole, so that the elastic ribs are always tightly attached to the inner wall of the locking interface, forming a reliable mechanical lock. This double fixing structure not only effectively resists the displacement under dynamic loads such as wind and earthquakes, but also absorbs some energy through the deformation capacity of the elastic ribs, significantly improving the seismic performance of the curtain wall system.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a stable curtain wall frame, including two main load-bearing columns 1, with main load-bearing columns 2 installed at the lower ends of the two main load-bearing columns 1 via connectors 7. The main load-bearing columns 1 and 2 are respectively sleeved on both ends of the connectors 7. A crossbeam 3 is installed between the two main load-bearing columns 1 and between the two main load-bearing columns 2. A curtain wall panel 5 is provided between the two crossbeams 3. A transverse mounting groove 31 that mates with the curtain wall panel 5 is provided on the crossbeam 3. Several fixing mechanisms 4 are provided on both sides of the transverse mounting groove 31 on the upper surface of the crossbeam 3. The fixing mechanisms 4 are used to reinforce the curtain wall panel 5.

[0024] The main load-bearing column 1 and the main load-bearing column 2 are precisely assembled by special connectors 7. The two are respectively fitted onto both ends of the connectors 7 and form a fixed connection, together constituting a vertical support system that bears the overall load of the curtain wall. The column combination structure effectively disperses stress concentration points through the transition fit of the connectors 7, and forms a tight mechanical interlock at adjacent end faces, significantly improving the resistance to lateral displacement. The two ends of the beam 3 are respectively engaged and positioned with the assembled columns through the transverse mounting grooves 31 and connecting blocks 12, forming a stable frame structure. On this basis, the fixing mechanism 4 constructs a multi-constraint system between the curtain wall panel 5 and the frame, effectively suppressing the vibration response of the panel under wind load, and greatly improving the overall stability and deformation resistance of the curtain wall system.

[0025] The fixing mechanism 4 includes a support base 41 fixedly connected to the upper surface of the crossbeam 3. Several elastic ribs 42 arranged in a ring are fixedly connected to the upper surface of the support base 41. The elastic ribs 42 are L-shaped. A fixing rod 43 is fixedly connected to the middle of the upper surface of the support base 41. A conical top 44 is provided at the top of the fixing rod 43. A locking mechanism 45 is provided outside the elastic ribs 42. The locking mechanism 45 is used to tighten the elastic ribs 42.

[0026] The support base 41 is fixedly connected to the two preset positions on both sides of the upper surface of the crossbeam 3 by a full welding process. Before installation, the installation reference line is marked on the surface of the crossbeam 3 using a laser positioning system to ensure that the support base 41 is mirror symmetrical. The elastic rib 42 is made of high-strength spring steel and is formed into an L-shaped structure by a CNC progressive bending process. The elastic rib 42 is distributed in an equal-angled ring array with the central axis of the support base 41 as the reference. The fixing rod 43 is fixedly connected to the conical top 44 and the middle of the upper surface of the support base 41, forming a precise constraint and positioning for the curtain wall panel 5, which is used to strengthen the fixation of the curtain wall panel 5.

[0027] The locking mechanism 45 includes an annular strip clamp 451 sleeved on the outside of several elastic ribs 42. Several positioning holes are opened on the surface of the strip clamp 451. A lock head 452 is fixedly connected to one end of the strip clamp 451. The other end of the strip clamp 451 passes through the lock head 452 and extends therethrough. A buckle 453 is rotatably connected to the lock head 452 and the fixed end of the strip clamp 451.

[0028] The locking mechanism 45 adopts an adjustable design. Through the linkage between the annular strip clamp 451 and the bolt 453, the radial contraction of the fixing mechanism 4 can be precisely adjusted. When installing the curtain wall panel 5, the operator only needs to rotate the bolt 453 to make it pass through the positioning hole and lock it, so that the annular strip clamp 451 is evenly tightened along the circumference of the elastic rib 42. This can flexibly adjust the width of the fixing mechanism 4 according to actual needs during the installation process, ensuring that the base 6 of the curtain wall panel 5 and the beam 3 are quickly and accurately aligned. After the curtain wall panel 5 is installed, the tension of the elastic rib 42 is released, and the curtain wall panel 5 is firmly locked to the surface of the beam 3, effectively resisting external loads such as strong winds and vibrations, and significantly improving the overall stability and safety of the curtain wall structure.

[0029] Among them, the lower end of the curtain wall panel 5 is fixedly connected to the base 6, the lower side of the base 6 is snapped into the horizontal mounting groove 31, the middle of the upper side of the base 6 is provided with a fixing groove 61, the fixing groove 61 is used to fix the curtain wall panel 5, and several snap-in interfaces 62 are provided on both sides of the base 6, the snap-in interfaces 62 are snapped into the fixing mechanism 4.

[0030] The base 6 has several precision-machined snap-fit ​​interfaces 62 on both sides. The shape and size of these interfaces are precisely matched with the elastic ribs 42 and the conical top 44 of the fixing mechanism 4 to form a precise tolerance fit. A stable connection is achieved through an embedded snap-fit ​​method. During installation, the elastic ribs 42 are embedded into the snap-fit ​​interfaces 62 within the deformation range. Together with the positioning effect of the conical top 44 and the fixing groove 61, they form a constraint to ensure that the base 6 and the fixing mechanism 4 are tightly engaged during the fixing of the curtain wall panel 5 to the horizontal beam 3. This effectively prevents the curtain wall panel 5 from shifting or loosening, and provides a reliable connection guarantee for the overall structure of the curtain wall.

[0031] Among them, the main load-bearing column 1 and the main load-bearing column 2 are assembled by the connector 7. The two are respectively sleeved on both ends of the connector 7, and the adjacent end faces of the main load-bearing column 1 and the main load-bearing column 2 are tightly fitted.

[0032] The connector 7 has a hollow column structure and is precisely embedded in the pre-opened assembly cavity inside the main load-bearing column 1 and the main load-bearing column 2. The main load-bearing column 1 and the main load-bearing column 2 are respectively fitted onto the outside of the connector 7 from both ends. The inner wall of the connector 7 forms an interference fit with the outer wall of the connector 7. The adjacent end faces are tightly fitted after high-precision milling. The double fastening of the locating pin and the high-strength bolt ensures the structural strength and stability of the column splicing and effectively improves the overall load-bearing performance of the curtain wall frame.

[0033] Among them, vertical mounting grooves 11 are provided on the inner sides of the two main load-bearing columns 1 and 2. The vertical mounting grooves 11 are used to engage with the two sides of the curtain wall panel 5. Connecting blocks 12 are fixedly installed on the inner sides of the two main load-bearing columns 1 and 2. Both ends of the crossbeam 3 are engaged with the connecting blocks 12.

[0034] High-precision vertical mounting grooves 11 are milled on opposite sides of the main load-bearing column 1 and the main load-bearing column 2. The cross-sectional shape of these grooves forms a precise tolerance fit with the snap-fit ​​flanges on both sides of the curtain wall panel 5. The curtain wall panel 5 is snapped and fixed on both sides through an embedded installation method. The vertical mounting grooves 11 not only provide vertical positioning constraints for the curtain wall panel 5, but also form a T-shaped snap-fit ​​structure with the connecting blocks 12 and the crossbeams 3 on the main load-bearing columns 1 and 2, realizing the connection between the crossbeams 3 and the columns, and together constructing a three-dimensional support frame for the stable installation of the curtain wall panel 5.

[0035] Among them, auxiliary fasteners 8 are provided on the outer sides of the two main load-bearing columns 1 and the two main load-bearing columns 2. The auxiliary fasteners 8 are used to fix the curtain wall frame to the wall.

[0036] The auxiliary fastener 8 is made of alloy steel and is pre-fixed to the building wall using a double bolt anchoring method. After installation, the main load-bearing column 1 and the main load-bearing column 2 are reliably connected to the auxiliary fastener 8 through the L-shaped connecting piece 9, forming a multi-directional constraint anchoring system. This system securely installs the entire curtain wall frame on the outside of the wall, effectively resisting external loads such as wind loads and earthquakes, and ensuring the long-term safe and stable operation of the curtain wall system.

[0037] Among them, the two main load-bearing columns 1 and the two main load-bearing columns 2 are connected to the auxiliary fixing parts 8 through L-shaped connecting pieces 9;

[0038] The main load-bearing column 1 and the main load-bearing column 2 are fixedly connected to the auxiliary fastener 8 by the L-shaped connecting piece 9, which ensures the vertical stability of the main load-bearing column 1 and the main load-bearing column 2. Furthermore, the mechanical characteristics of the L-shaped structure effectively disperse the horizontal load, so that the curtain wall frame and the building wall form a cooperative force-bearing system, which significantly improves the overall structure's resistance to lateral displacement and seismic performance.

[0039] In summary, when using this stable curtain wall frame, firstly, measure and mark the positions of the fixed frame on the building wall. Next, fix the auxiliary fasteners 8 to the building wall sequentially with screws. Then, fix one half of the L-shaped connecting piece 9 to both sides of the surface of each auxiliary fastener 8 with screws. Next, place a section of the main load-bearing column 2 vertically between the two L-shaped connecting pieces 9 on the lower left side of one of the auxiliary fasteners 8 in a group of four, ensuring that the side of the main load-bearing column 2 with the vertical mounting groove 11 faces right, guaranteeing its verticality and meeting installation requirements. Finally, screw the sides of the two L-shaped connecting pieces 9 that are in contact with the main load-bearing column 2. Next, insert the connector 7 inside the upper end of the main load-bearing column 2, so that the main load-bearing column 2 wraps around half of the connector 7, and install the main load-bearing column 1 on the other end of the connector 7, ensuring that the adjacent end faces of the two are tightly fitted to ensure the connection strength and stability of the columns. Then, install the crossbeam 3 on the right end of the main load-bearing column 2, and suspend the crossbeam 3 on the connecting block 12. The crossbeam 3 is equipped with several fixing mechanisms 4. Twist the buckle 453 to the left by hand to reduce the diameter of the circle formed by the strip clamp 451 and squeeze the elastic rib 42, so that the elastic rib 42 is gathered within the cross-sectional diameter of the elastic rib 42. Then, take out the curtain wall panel 5 and insert the left side of the curtain wall panel 5 into the vertical mounting groove 11 on the main load-bearing column 2. The base 6 slides down and the fixing groove 61 on the base 6 fits onto the fixing mechanism 4, so that the locking mechanism 45 on the fixing mechanism 4 protrudes from the base 6. The protruding part under the base 6 on the lower side of the curtain wall panel 5 is aligned with the transverse mounting groove 31 on the crossbeam 3 on the main load-bearing column 2. At this time, the buckle 453 can be turned to the right to increase the diameter of the ring formed by the strip clamp 451. The elastic rib 42 unfolds inside the strip clamp 451 by inertia, firmly fixing the base 6 to the surface of the crossbeam 3. Then, the crossbeam 3 is installed on the right end of the main load-bearing column 1. While suspending the crossbeam 3 on the connecting block 12, the transverse mounting groove 31 on the lower side of the main load-bearing column 1 is engaged with the top of the curtain wall panel 5. Then, the other section of the main load-bearing column 1 is... Take out the main load-bearing column 2 and splice them together using connector 7. Then, place the side with connecting block 12 facing the two horizontal beams 3 and insert it into the other end of the horizontal beam 3. This allows the connecting parts at both ends of the horizontal beam 3 to engage with the connecting blocks 12 on the opposite sides of the main load-bearing column 1 and the main load-bearing column 2. The connecting blocks 12 can be precisely embedded into the grooves inside the horizontal beam 3. Then, use screws to fix the sides of the main load-bearing column 1 and the main load-bearing column 2 to the two auxiliary fixing parts 8 on the right side using L-shaped connecting pieces 9. This ensures that the connection between the horizontal beam 3 and the column is stable, forming a stable frame structure. By doing so, the installation of the front curtain wall can be completed, which plays a good role in fixing the curtain wall panel 5 and enhances the stability of the curtain wall installation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
