Description

Technical Field

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

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

[0003] Since the adjustable angle curtain wall uses external force to forcibly deform the panels, it is in a torsional stress state for a long time, which may affect the mechanical properties of brittle materials such as glass. In addition, during the design and installation process, there are embedded parts that are offset and the embedded parts that are supplemented are not firm, which can easily affect the stability and safety of the curtain wall. In addition, the curtain wall needs to have a certain wind resistance to withstand the impact of strong winds. If the wind resistance is insufficient, the curtain wall will collapse or be damaged.

[0004] Most of the adjustable angle curtain wall structures in the prior art 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 two sub-frames. However, this structure easily causes the curtain wall to rotate due to external forces, and the stability and firmness of the installation 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, a large amount of energy will be lost. 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 heat insulation effect of the curtain wall structure, improve the airtightness, and reduce the overall energy consumption of the curtain wall.

[0012] Furthermore, a boss protruding toward both sides is provided at the bottom end of the trigger portion, and when the trigger portion moves upward to an initial position, the boss abuts against the mounting seat.

[0013] Furthermore, the second locking member includes a mounting plate and a toothed block disposed on the mounting plate, 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.

When the glass curtain walls on both sides are installed, the support part is connected to the second locking member to support and adjust the angle of one end of the glass curtain wall, so as to facilitate the positioning of the curtain wall. After the angle adjustment of the glass curtain wall and the sub-frame is completed, the plug-in part is aligned with the corresponding socket part, and the trigger part is driven so that the plug-in part is plugged into the socket part, and the glass curtain wall is completely fixed to the sub-frame, thereby increasing the connection stability of the glass curtain wall. And by providing a sealing assembly and a cover, the gap between two adjacent glass curtain walls is closed, effectively achieving the effect of energy saving and heat insulation, improving the airtightness, and reducing the overall energy consumption of the curtain wall.

[0018] In addition, by connecting the mounting seat to the sub-frame and providing a slider slidably connected to the mounting seat, when the trigger part is driven to move downward, the slider slides relative to the mounting seat 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 block is adjusted, so as to facilitate the plug-in and fixation of the socket part and the plug-in part. When the two are plugged in 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.

[0019] 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.

[0027] The energy-saving and heat-insulating combined curtain wall structure of this embodiment is provided with a sub-frame 4 wrapped around the outside of the column 1, and a first locking member 5 is provided in the accommodating cavity 401 of the sub-frame 4, and a second locking member 6 is provided on the glass 3. When the glass 3 curtain walls on both sides are installed, the support portion 402 is connected to the second locking member 6 to support and adjust the angle of one end of the glass 3 curtain wall, so as to facilitate the positioning of the curtain wall. After the angle adjustment of the glass 3 curtain wall and the sub-frame 4 is completed, the plug-in portion 506 is aligned with the corresponding socket portion, and the trigger portion 501 is driven so that the plug-in portion 506 is plugged into the socket portion, and the glass 3 curtain wall is completely fixed to the sub-frame 4, thereby increasing the connection stability of the glass 3 curtain wall. And by providing a sealing assembly 7 and a cover 8, the gap between two adjacent glass 3 curtain walls is closed, effectively achieving the effect of energy saving and heat insulation, improving the airtightness, and reducing the overall energy consumption of the curtain wall.

[0028] 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, the glass 3 curtain wall of this embodiment can also be replaced by, for example, decorative wall panels arranged on the outside, which is not limited here.

[0029] As a preferred implementation mode, Figures 4 to 6As 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 provided between the baffle 504 and the mounting seat 502, and two plug-in parts 506 are connected to both sides of the slider 503. The trigger part 501 penetrates the mounting seat 502 from top to bottom, and the trigger part 501 drives the slider 503 to slide left and right, so that the second locking block is clamped and fixed with the plug-in part 506.

[0030] As Figure 4 As shown in FIG. , the mounting seat 502 is formed into a rectangular structure, combined with Figure 1 As shown, the sub-frame 4 is wrapped and fixed along both sides of the keel and reinforced by rivets to connect the sub-frame 4 to the keel, further increasing the structural strength of the sub-frame 4. The upper part of the sub-frame 4 is bent to form a rectangular accommodating cavity 401, and the side of the accommodating cavity 401 close to the outside has an opening, and the mounting seat 502 is adapted to the structure of the accommodating cavity 401.

[0031] The first locking members 5 of this embodiment are arranged at intervals along the height direction of the column 1 according to the installation node. Correspondingly, the second locking members 6 on the glass curtain wall 3 are arranged at corresponding positions to the first locking members 5. As a specific implementation method, the second locking members 6 can be set to various angle specifications. 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.

[0032] In order to facilitate the installation of the first locking member 5, when the elastic member 505 is in a free state, one side of the slider 503 partially protrudes, and a long groove from outside to inside needs to be set on the sub-frame 4 on this side to avoid the slider 503, so as to facilitate smooth installation. The setting of the long groove can be prefabricated according to the position of the node, which provides convenience for on-site assembly.

[0033] In this embodiment, by connecting the mounting seat 502 to the sub-frame 4 and providing a slider 503 slidably connected to the mounting seat 502, when the trigger part 501 is driven to move 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 part of the second locking block is adjusted to facilitate the plug-in fixation of the socket part and the plug-in part 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.

[0034] Furthermore, if Figures 4 to 6As shown, the mounting seat 502 has a cavity with an opening at one end, and the baffle 504 is adapted to the cavity in shape. The slider 503 slides along the opening direction of the mounting seat 502, and the mounting seat 502 is provided with a through hole, and the slider 503 slides out of the through hole. The cavity is formed into a rectangular structure, and the baffle 504 and the slider 503 are formed in one piece. When the slider 503 moves along the horizontal direction of the building, the baffle 504 slides relative to the mounting seat 502, and the mounting seat 502 provides a guiding effect on the baffle 504, ensuring the position accuracy of the connection between the plug-in part 506 and the socket part, thereby improving the accuracy of the curtain wall installation.

[0035] 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, and a rectangular opening groove 5011 is formed on the triggering part 501, and the triggering part 501 is plugged into the connecting section 5033 through the opening groove 5011. The triggering part 501 is formed into a rectangular long strip plate structure, four elastic members 505 are arranged in the cavity of the mounting seat 502 along the sliding direction of the slider 503, and four blind holes are formed on the baffle 504 to facilitate the positioning of the four elastic members 505. The elastic members 505 of this embodiment are telescopic springs.

[0036] In addition, if Figures 4 to 6 As shown, the longitudinal section of the groove 5032 is formed into a right triangle, and the body 5031 and the hypotenuse of the groove 5032 are formed with an inclined sliding surface 5034, and the trigger part 501 abuts against the sliding surface 5034. When the trigger part 501 is driven to move 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 of the trigger part 501 is released, the elastic member 505 releases energy, the slider 503 moves in the opposite direction, and the trigger part 501 moves upward to reset.

[0037] like Figures 4 to 6 As shown, the trigger part 501 is provided with an open groove 5011 which passes through the lower end from bottom to top, and the lower end of the trigger part 501 abuts on the sliding surface 5034. When the trigger part 501 is subjected to an external downward force, the lower end of the trigger part 501 slides along the sliding surface 5034, and the slider 503 moves in the horizontal direction, thereby adjusting the positions of the plug-in parts 506 on both sides. This is to facilitate the separation or clamping of the glass 3 curtain wall and the secondary frame 4. By providing an inclined sliding surface 5034, the trigger part 501 abuts against the sliding surface 5034, which increases the smoothness of movement of the slider 503 and the plug-in part 506, provides convenience for installation at the construction site, effectively improves the installation efficiency, and reduces special parts.

[0038] Preferably, the bottom end of the trigger part 501 is provided with a boss 5012 protruding to both sides. When the trigger part 501 moves up to the initial position, the boss 5012 abuts against the mounting seat 502. By providing the boss 5012, the trigger part 501 is prevented from being separated from the mounting seat 502. Figure 1 As shown, the trigger part 501 of this embodiment faces one end outside the window. After the glass curtain wall 3 is installed, the trigger part 501 is blocked by the cover 8.

[0039] Preferably, if Figures 1 to 3 As shown, the second locking member 6 includes a mounting plate 601 and a toothed block 602 disposed on the mounting plate 601. The toothed block 602 is formed with a plurality of tooth grooves 603 arranged at equal intervals, and the tooth grooves 603 are adapted to the shape of the plug-in portion 506. As mentioned above, a round hole is provided on the mounting plate 601, and a bolt is connected to a screw sleeve pre-embedded on the glass 3 through the round hole, so as to fix the second locking member 6 on the glass 3 curtain wall. The plurality of tooth grooves 603 are the above-mentioned socket portion.

[0040] 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 configuration facilitates the disassembly and installation of the second locking member 6, thereby improving the flexibility and applicability of the curtain wall structure.

[0041] Furthermore, if Figures 1 to 3 As shown, the front end of the toothed block 602 is formed into a convex arc shape, the support portion 402 is bent into a concave arc shape, and the toothed block 602 is 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, and a connecting rod 9 is provided between the support portion 402 and the toothed block 602. By setting the front end of the toothed block 602 into a convex arc shape and the support portion 402 into a concave arc shape, during the construction and adjustment process of the glass 3 curtain wall, the front end of the glass 3 curtain wall is positioned and supported, and the two are connected by setting the connecting rod 9. One end of the connecting rod 9 is screwed to the toothed block 602. When adjusting the angle, the connecting rod 9 can be pulled to fine-tune the angle of the glass 3 curtain wall, which increases the convenience of adjustment and reduces the adjustment time, not only improving the accuracy of the installation position of the curtain wall, but also improving the installation efficiency.

[0042] In addition, if Figure 7As shown, a protrusion 403 protruding toward the center is provided on the side of the sub-frame 4 close to the outside, and a first buckle 10 connected to the protrusion 403 is provided on the cover 8; the first buckle 10 is made of elastic material, and the first buckle 10 is fixedly connected to the protrusion 403. The protrusion 403 on the sub-frame 4 of this embodiment is formed by bending and extrusion, and the protrusion 403 can not only play a role in fixing the cover 8, but also make the connection between the sealing assembly 7 and the sub-frame 4 more firmly, thereby increasing the overall strength of the curtain wall structure. The cover 8 is arranged along the height direction of the glass 3 curtain wall.

[0043] like Figure 7 As shown, a hook plate 11 is provided on the first locking member 5, and a second buckle 12 is provided on the column 1, 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 plugging and fixing of the cover 8 and the first locking member 5.

[0044] The sealing assembly 7 of this embodiment adopts the structural adhesive in the prior art. Through the joint 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 reduced adhesion and eventual hardening and falling off.

[0045] The connection and installation sequence of the energy-saving and heat-insulating curtain wall structure of this embodiment is: First, measure and lay out: Based on the layout marks made 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 lines of each part of the curtain wall.

[0046] 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. Use weather-resistant sealant to seal the indirect joints of the sub-frame 4 and the joint gaps between the sub-frames 4 and 4.

[0047] Next, install the glass 3: After the sub-frame 4 is installed, install the glass 3. During installation, pay attention to the cleanliness and ventilation of the glass 3 and the sub-panel injection layer, the temperature should be between 15-30 degrees, and the relative humidity should be above 50%. Before injection, a qualified compatibility report must be obtained, and the injection should be dense, uniform, and free of bubbles.

[0048] Finally, ‌Gluing‌: After the glass 3 is installed, the structural glue is applied. Before gluing, make sure that the surface of the sub-frame 4 and the glass 3 is clean, free of dust and impurities, and then inject and cure the structural glue.

[0049] 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 principle of the present invention should be included in the protection scope of the present invention.
