Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall structures, in particular to an energy-saving and heat-insulating combined curtain wall structure. Background Art

[0002] Adjustable angle curtain wall structure is a new type of building exterior wall. Compared with traditional glass curtain walls, adjustable angle glass curtain walls can be adjusted during installation according to actual needs, making them more in line with building appearance requirements.

[0003] Because adjustable-angle curtain walls use external forces to forcibly deform panels, long-term torsional stress can affect the mechanical properties of brittle materials like glass. Furthermore, during the design and installation process, problems such as misaligned embedded components and loose, post-installed embedded components can easily compromise the curtain wall's stability and safety. Furthermore, curtain walls must possess a certain degree of wind resistance to withstand strong winds. Inadequate wind resistance can lead to collapse or damage.

[0004] Most of the adjustable angle curtain wall structures in the existing technology use sub-frame profiles to connect the curtain wall, and the rotation of the curtain wall relative to the keel is achieved through a swivel connection between the two sub-frames. However, this structure easily causes the curtain wall to rotate due to external forces, and the installation stability and firmness are poor, posing a safety hazard.

[0005] In addition, the curtain wall is the outer shell of the building, directly facing the outdoor environment. If there are no insulation measures, it will lead to a large amount of energy loss. In particular, the glass curtain wall has a fast heat transfer speed, which can easily lead to large fluctuations in indoor temperature and high humidity, increasing the energy consumption of indoor air conditioning heating and cooling. Summary of the Invention

[0006] In view of this, the present invention aims to propose an energy-saving and heat-insulating combined curtain wall structure to increase the stability and firmness of the curtain wall structure installation, improve the thermal insulation effect of the curtain wall structure, improve the airtightness, and reduce the overall energy consumption of the curtain wall.

[0007] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0008] An energy-saving and heat-insulating combined curtain wall structure, comprising columns, beams, and glass, wherein the columns are fixedly connected to the beams, a sub-frame is provided on the outside of the columns, a receiving cavity is provided on the side of the sub-frame close to the outside, and a first locking member is installed in the receiving cavity;

[0009] A second locking piece is provided on a side of the glass close to the accommodating cavity, and a supporting portion is formed on the sub-frame and is in contact with the second locking piece;

[0010] The second locking member is provided with a socket portion, which drives the trigger portion of the first locking member, and the plug portion of the first locking member is plugged into the socket portion;

[0011] A sealing component is provided between the sub-frame and the second locking member, and a sealing cover is provided between the two sealing components.

[0012] Furthermore, the first locking member includes a mounting seat abutting against the sub-frame, a slider slidably connected to the mounting seat, a baffle connected to the slider, and an elastic member provided between the baffle and the mounting seat;

[0013] The two plug-in parts are connected to both sides of the slider;

[0014] The trigger portion passes through the mounting seat from top to bottom, and the trigger portion drives the slider to slide left and right, so that the second locking member is engaged and fixed with the plug-in portion.

[0015] Furthermore, the mounting seat has a cavity with one end open, and the baffle has an outer shape that matches the cavity;

[0016] The sliding block slides along the opening direction of the mounting seat, and the mounting seat is provided with a through hole, and the sliding block slides out from the through hole.

[0017] Furthermore, the slider includes a body and grooves formed on both sides of the body;

[0018] A connecting section is formed between the two grooves, and a rectangular opening groove is formed on the trigger portion;

[0019] The trigger portion is plugged into the connecting section through the opening slot.

[0020] Furthermore, the longitudinal section of the groove is formed into a right triangle, the body and the hypotenuse of the groove are formed with an inclined sliding surface, and the trigger portion abuts against the sliding surface;

[0021] When the trigger portion is driven to move downward, the slider is driven to slide along the mounting seat, and the elastic member is compressed to store energy. When the force of the trigger portion is released, the elastic member releases the energy, the slider moves in the opposite direction, and the trigger portion moves upward to reset.

[0022] Furthermore, the bottom end of the trigger portion is provided with bosses protruding toward both sides, and when the trigger portion moves upward to an initial position, the bosses abut against the mounting seat.

[0023] Furthermore, the second locking member includes a mounting plate and a toothed block provided on the mounting plate, wherein the toothed block is formed with a plurality of tooth grooves arranged at equal intervals, and the tooth grooves are adapted to the outer shape of the plug-in portion.

[0024] Furthermore, the front end of the toothed block is formed into a convex arc shape, the support portion is bent into a concave arc shape, and the toothed block is abutted and connected to the support portion; a threaded hole is formed on the toothed block, and a slide groove is formed on the support portion along the extension direction of the support portion;

[0025] A connecting rod is provided between the supporting portion and the toothed block.

[0026] Furthermore, a protrusion protruding toward the center is provided on the side of the sub-frame close to the outside of the room, and a first buckle connected to the protrusion is provided on the cover;

[0028] Furthermore, a hook-shaped plate is provided on the first locking member, a second buckle is provided on the column, and the hook-shaped plate is fixedly connected to the second buckle.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] The energy-saving and heat-insulating combined curtain wall structure described in the present invention is achieved by providing a covering sub-frame on the outside of the column, and providing a first locking member in the accommodating cavity of the sub-frame, while providing a second locking member on the glass. When the glass curtain walls on both sides are installed, the support portion is connected to the second locking member to support one end of the glass curtain wall and adjust the angle, thereby facilitating the positioning of the curtain wall. After the angle between the glass curtain wall and the sub-frame is adjusted, the plug-in portion is aligned with the corresponding socket portion, and the trigger portion is driven to plug the plug-in portion into the socket portion, completely fixing the glass curtain wall to the sub-frame, thereby increasing the stability of the connection of the glass curtain wall. In addition, by providing a sealing assembly and a cover, the gap between two adjacent glass curtain walls is sealed, effectively achieving the effect of energy saving and heat insulation, improving the airtightness, and reducing the overall energy consumption of the curtain wall.

[0031] In addition, by connecting the mounting base to the sub-frame and providing a slider slidably connected to the mounting base, when the trigger part is driven downward, the slider slides relative to the mounting base along the horizontal direction of the building, so that the distance between the plug-in parts on both sides and the socket part of the second locking member is adjusted to facilitate the plug-in and fixation of the socket part and the plug-in part. When the two are plugged into place, the position between the glass curtain wall and the sub-frame is completely fixed, so as to increase the overall structure of the glass curtain wall, improve the wind resistance, and increase the stability and safety of the curtain wall structure.

[0032] In addition, by providing an inclined sliding surface, the trigger part abuts against the sliding surface, which increases the smoothness of movement of the slider and the plug-in part, provides convenience for installation at the construction site, effectively improves installation efficiency, and reduces special parts.

[0051] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0052] This embodiment relates to an energy-saving and heat-insulating combined curtain wall structure. As a whole, Figure 1 As shown, the curtain wall structure includes a column 1, a beam 2 and a glass 3. The column 1 is fixedly connected to the beam 2. A sub-frame 4 is provided on the outside of the column 1. A accommodating cavity 401 is provided on the side of the sub-frame 4 close to the outside. A first locking member 5 is installed in the accommodating cavity 401. A second locking member 6 is provided on the side of the glass 3 close to the accommodating cavity 401. A support portion 402 is formed on the sub-frame 4 and abuts against the second locking member 6. A socket portion is provided on the second locking member 6, which drives a trigger portion 501 of the first locking member 5. The plug-in portion 506 of the first locking member 5 is plugged into the socket portion. A sealing component 7 is provided between the sub-frame 4 and the second locking member 6, and a cover 8 is provided between the two sealing components 7.

[0053] The energy-saving and heat-insulating combined curtain wall structure of this embodiment is characterized by providing a covering sub-frame 4 on the outside of the column 1, and providing a first locking member 5 in the accommodating cavity 401 of the sub-frame 4, while providing a second locking member 6 on the glass 3. When the glass 3 curtain walls on both sides are installed, the support portion 402 is abutted and connected with the second locking member 6, supporting one end of the glass 3 curtain wall and adjusting the angle, thereby facilitating the positioning of the curtain wall. After the angle between the glass 3 curtain wall and the sub-frame 4 is adjusted, the plug-in portion 506 is aligned with the corresponding socket portion, and the trigger portion 501 is driven to plug the plug-in portion 506 into the socket portion, completely fixing the glass 3 curtain wall to the sub-frame 4, thereby increasing the connection stability of the glass 3 curtain wall. In addition, by providing a sealing assembly 7 and a cover 8, the gap between two adjacent glass 3 curtain walls is sealed, effectively achieving the effect of energy saving and heat insulation, improving airtightness, and reducing the overall energy consumption of the curtain wall.

[0054] Based on the above overall introduction, this embodiment is an exemplary structure of the energy-saving and heat-insulating combined curtain wall structure. This embodiment provides an example of connecting the glass 3 curtain wall and the column 1. Of course, under different construction requirements, for example, decorative wall panels provided on the outside can also be used to replace the glass 3 curtain wall of this embodiment, which is not limited here.

[0055] As a preferred embodiment, Figures 4 to 6 As shown, the first locking member 5 includes a mounting seat 502 abutting against the sub-frame 4, a slider 503 slidably connected to the mounting seat 502, a baffle 504 connected to the slider 503, and an elastic member 505 disposed between the baffle 504 and the mounting seat 502. Two plug-in portions 506 are connected to either side of the slider 503. A trigger portion 501 extends from top to bottom through the mounting seat 502, driving the slider 503 to slide left and right, thereby engaging and fixing the second locking member 6 with the plug-in portions 506.

[0056] As Figure 4 As shown in FIG, the mounting base 502 is formed into a rectangular structure, Figure 1 As shown, the sub-frame 4 is wrapped and fixed along both sides of the keel and reinforced with rivets to connect the sub-frame 4 to the keel, further increasing the structural strength of the sub-frame 4. The upper portion of the sub-frame 4 is bent to form a rectangular accommodating cavity 401. The side of the accommodating cavity 401 facing the outside has an opening, and the mounting seat 502 is adapted to the structure of the accommodating cavity 401.

[0057] In this embodiment, the first locking members 5 are spaced apart along the height direction of the column 1 according to the installation nodes. Accordingly, the second locking members 6 on the glass curtain wall 3 are arranged at positions corresponding to the first locking members 5. As a specific implementation method, the second locking members 6 can be set at various angles. A screw sleeve with a threaded hole should be pre-embedded on the glass 3, and the glass curtain wall 3 and the second locking members 6 are fixed by bolts.

[0058] To facilitate installation of the first locking member 5, when the elastic member 505 is in the free state, one side of the slider 503 partially protrudes, and a long groove extending from the outside to the inside is required on the sub-frame 4 on that side to avoid the slider 503 and facilitate smooth installation. The long groove can be prefabricated according to the location of the node to facilitate on-site assembly.

[0059] In this embodiment, by connecting the mounting seat 502 to the sub-frame 4 and providing a slider 503 that is slidably connected to the mounting seat 502, when the trigger part 501 is driven downward, the slider 503 slides relative to the mounting seat 502 along the horizontal direction of the building, so that the distance between the plug-in parts 506 on both sides and the socket parts of the second locking member 6 is adjusted to facilitate the plug-in and fixation of the socket parts and the plug-in parts 506. When the two are plugged into place, the position between the glass 3 curtain wall and the sub-frame 4 is completely fixed, so as to increase the overall structure of the glass 3 curtain wall, improve the wind resistance, and increase the stability and safety of the curtain wall structure.

[0060] Furthermore, if Figures 4 to 6 As shown, mounting base 502 has a cavity with an open end, and baffle 504 is shaped to match the cavity. Slider 503 slides along the opening of mounting base 502. Mounting base 502 has a through-hole through which slider 503 slides out. The cavity is rectangular, and baffle 504 and slider 503 are integrally formed. When slider 503 moves horizontally along the building, baffle 504 slides relative to mounting base 502. Mounting base 502 guides baffle 504, ensuring the accurate connection between plug-in connector 506 and socket-outlet connector, thereby improving the accuracy of curtain wall installation.

[0061] Furthermore, if Figures 4 to 6 As shown, the slider 503 includes a body 5031 and grooves 5032 formed on both sides of the body 5031. A connecting section 5033 is formed between the two grooves 5032. The trigger portion 501 is formed with a rectangular opening 5011, and the trigger portion 501 is inserted into the connecting section 5033 through the opening 5011. The trigger portion 501 is formed into a rectangular long plate structure. Four elastic members 505 are arranged in the cavity of the mounting seat 502 along the sliding direction of the slider 503. Four blind holes are formed in the baffle 504 to facilitate the positioning of the four elastic members 505. In this embodiment, the elastic members 505 are telescopic springs.

[0062] In addition, if Figures 4 to 6As shown, the longitudinal cross-section of the groove 5032 is formed into a right triangle. The body 5031 and the hypotenuse of the groove 5032 are formed with an inclined sliding surface 5034, and the trigger portion 501 abuts against the sliding surface 5034. When the trigger portion 501 is driven downward, the slider 503 is driven to slide along the mounting seat 502, and the elastic member 505 is compressed to store energy. When the force applied by the trigger portion 501 is released, the elastic member 505 releases the energy, the slider 503 moves in the opposite direction, and the trigger portion 501 moves upward and resets.

[0063] like Figures 4 to 6 As shown, the trigger portion 501 is provided with an open slot 5011 extending upward from the bottom, with the lower end of the trigger portion 501 abutting against a sliding surface 5034. When the trigger portion 501 is subjected to an external downward force, the lower end of the trigger portion 501 slides along the sliding surface 5034, causing the slider 503 to move horizontally, thereby adjusting the position of the plug-in portions 506 on both sides. This facilitates the separation or engagement of the glass curtain wall 3 with the sub-frame 4. By providing the inclined sliding surfaces 5034, the trigger portion 501 abuts against the sliding surfaces 5034, improving the smoothness of movement of the slider 503 and the plug-in portion 506, providing convenience for installation at the construction site, effectively improving installation efficiency, and reducing the number of specialized parts.

[0064] Preferably, the bottom end of the trigger portion 501 is provided with bosses 5012 protruding to both sides. When the trigger portion 501 moves up to the initial position, the bosses 5012 abut against the mounting seat 502. By providing the bosses 5012, the trigger portion 501 is prevented from being separated from the mounting seat 502. Figure 1 As shown, the trigger portion 501 of this embodiment faces one end outside the window. After the glass curtain wall 3 is installed, the trigger portion 501 is blocked by the cover 8.

[0065] Preferably, if Figures 1 to 3 As shown, the second locking member 6 includes a mounting plate 601 and a toothed block 602 mounted on the mounting plate 601. The toothed block 602 is formed with a plurality of equally spaced tooth grooves 603 that align with the outer shape of the plug-in portion 506. As previously mentioned, the mounting plate 601 is provided with circular holes through which bolts connect with pre-embedded screw sleeves on the glass 3, thereby securing the second locking member 6 to the glass 3 curtain wall. The plurality of tooth grooves 603 serve as the aforementioned sockets.

[0066] like Figures 1 to 3 As shown, one or more tooth grooves 603 can be provided on the toothed block 602, and tooth grooves 603 at different angles can also be provided to adapt to curtain wall installation at different angles. Such a setting facilitates the disassembly and installation of the second locking member 6, thereby improving the flexibility and applicability of the curtain wall structure.

[0067] Furthermore, if Figures 1 to 3As shown, the front end of the toothed block 602 is formed into a convex arc shape, and the support portion 402 is bent into a concave arc shape. The toothed block 602 is abutted and connected to the support portion 402. A threaded hole is formed on the toothed block 602, and a slide groove is formed on the support portion 402 along the extension direction of the support portion 402. A connecting rod 9 is provided between the support portion 402 and the toothed block 602. By configuring the front end of the toothed block 602 into a convex arc shape and the support portion 402 into a concave arc shape, the front end of the glass curtain wall 3 is positioned and supported during the construction and adjustment process of the glass curtain wall 3, and the connecting rod 9 is provided to connect the two. One end of the connecting rod 9 is threadedly connected to the toothed block 602. When adjusting the angle, the connecting rod 9 can be pulled to fine-tune the angle of the glass curtain wall 3, increasing the convenience of adjustment and reducing adjustment time. This not only improves the installation position accuracy of the curtain wall, but also improves installation efficiency.

[0068] In addition, if Figure 7 As shown, the side of the sub-frame 4 closest to the outside of the room is provided with a protrusion 403 protruding toward the center. The cover 8 is provided with a first clip 10 connected to the protrusion 403. The first clip 10 is made of an elastic material and is fixedly engaged with the protrusion 403. In this embodiment, the protrusion 403 on the sub-frame 4 is formed by bending and extrusion. The protrusion 403 not only secures the cover 8 but also strengthens the connection between the sealing assembly 7 and the sub-frame 4, thereby increasing the overall strength of the curtain wall structure. The cover 8 extends along the entire length of the glass 3 curtain wall.

[0069] like Figure 7 As shown, the first locking member 5 is provided with a hook plate 11, and the column 1 is provided with a second buckle 12, and the hook plate 11 is fixedly engaged with the second buckle 12. The hook plate 11 is first fixed to the column 1 before the sub-frame 4 is installed. The first buckle 10 and the second buckle 12 of this embodiment are both made of elastic plastic material to facilitate the insertion and fixation of the cover 8 and the first locking member 5.

[0070] The sealing assembly 7 of this embodiment adopts the structural adhesive in the prior art. Through the combined action of the sealing cover 8 and the structural adhesive, the airtightness of the curtain wall structure can be effectively ensured and energy consumption can be reduced. Figures 1 to 3 As shown in the figure, the cover 8 can also fix and limit the sealing component 7, so as to prevent the sealing component 7 from aging after long-term use, resulting in a decrease in adhesion and eventual hardening and falling off.

[0071] The connection and installation sequence of the energy-saving and heat-insulating curtain wall structure of this embodiment is:

[0072] First, measure and lay out: Based on the layout marks during the structural review and the cross center line of the embedded parts, determine the installation reference line, including the keel arrangement reference and the horizontal elevation line of each part of the curtain wall.

[0073] Secondly, install the sub-frame 4: fix the connecting aluminum parts to the corresponding positions of the aluminum columns, note that the connection between the beam and the column should meet the design requirements, and use weather-resistant sealant to seal the indirect joints of the sub-frame 4 and the joint gaps between the sub-frames 4.

[0074] Next, install glass 3: After the subframe 4 is installed, proceed with glass 3. During installation, ensure that the glass 3 and the subframe's glue layer are clean and well-ventilated. The temperature should be between 15-30°C and the relative humidity should be above 50%. Before glue injection, a qualified compatibility report must be obtained, and the glue injection must be dense, uniform, and free of bubbles.

[0075] Finally, ‌Gluing‌: After the glass 3 is installed, the structural glue is applied. Before gluing, ensure that the surface of the sub-frame 4 and the glass 3 is clean, free of dust and impurities. Then, the structural glue is injected and cured.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
