Description

Technical Field

[0001] The invention relates to the technical field of building curtain walls, and in particular to a splicable building energy-saving curtain wall. Background Art

[0002] The building curtain wall is a non-load-bearing exterior wall structure, which is mainly used for the exterior of the building to protect the interior of the building, improve the appearance, and provide heat insulation, sound insulation, and wind and rain protection. The curtain wall is usually made of aluminum alloy, glass, stone, concrete and other materials, and is characterized by light weight, high strength and beautiful appearance.

[0003] However, there are still some problems in the assembly of existing building curtain walls. During the installation of traditional building curtain walls, the docking between curtain wall panels often relies on manual adjustment and high-precision manual operation, which is prone to problems such as inaccurate docking and position errors. Traditional curtain wall systems often lack flexibility in ventilation design, especially in warm climates. The air tightness and ventilation of the curtain wall are often unbalanced. The connection between traditional curtain wall panels and the main body of the building is often not tight enough or lacks sufficient locking structure, which causes the curtain wall panels to loosen or shift under external forces, affecting the stability and seismic resistance of the structure. In terms of modular and standardized design, although some systems use prefabricated panels, they are often not efficient enough in actual engineering implementation. Therefore, the present invention proposes a splicable building energy-saving curtain wall to solve the problems mentioned in the above background technology. Summary of the invention

[0008] Preferably, a notch is provided at an upper corner of one back side of the support block, and a protrusion corresponding to the notch is provided at a lower corner of one back side of the insert block.

[0009] Preferably, a linkage panel is arranged between the two clamping mechanisms on the rear side of the curtain wall panel, and the linkage panel slides up and down on the beam frame, and the beam frame is provided with sliding grooves corresponding to the two ends of the linkage panel, and the sliding groove is provided with an extrusion spring corresponding to the linkage panel.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention can ensure the precise alignment of the upper and lower curtain wall panels during installation through the precise matching of the insert block and the support block, and the docking design of the notch and the convex block. The close contact between the curtain wall and the main body of the building is ensured by the close-fitting mechanism (rotating wheel, rotating frame, sliding shaft and other components) in the system by firmly fixing the curtain wall panel on the beam frame, thereby reducing the thermal bridge effect and further improving the thermal insulation performance. The design of the curtain wall panel also fully considers the possibility of natural ventilation. Through reasonable gaps and structural gaps, the external air can circulate under certain conditions, bringing about a natural cooling effect. Especially in warm climate areas, the temperature inside the building can be effectively reduced through appropriate ventilation design, thereby reducing the dependence on air conditioning and achieving passive energy saving.

[0017] 2. The spliced ​​curtain wall system of the present invention greatly improves the construction efficiency and installation convenience. First, the curtain wall panel is precisely docked with the insert block and the support block, so that the upper and lower curtain wall panels can be quickly and accurately positioned and spliced, which greatly simplifies the docking steps in the traditional curtain wall installation and reduces manual adjustment and docking errors. This modular and standardized design method ensures that the assembly process at the construction site can be completed quickly and reduces the labor cost. Secondly, the automatic positioning function of the side buckle block and the card slot block in the system ensures the rapid connection of the left and right curtain wall panels. Through the return action of the torsion spring, the automatic docking and resetting during the splicing process further simplifies the workers' operation, improves the installation efficiency and reduces installation errors.

[0018] 3. The present invention also demonstrates advantages in enhancing building safety. Through the tooth surface design (such as the contact between the tooth surface of the first wheel and the positioning plug plate and the rough surface), the combination of the curtain wall panel and the beam frame is more firmly avoided, and the loosening or displacement caused by external force interference during the splicing process is avoided, thereby improving the stability of the structure. In addition, the cooperation between the linked panels and the slide grooves and extrusion springs enables the curtain wall panels to be more closely combined, further increasing the stability and seismic resistance of the splicing structure. Moreover, the locking nut structure of the second wheel and the positioning plug plate in the design ensures the fixation of the entire curtain wall system through the locking effect after the splicing is completed, avoiding interference from external factors.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-7 A splicable building energy-saving curtain wall comprises a curtain wall panel 1 and a beam frame 2. The curtain wall panel 1 is located at the front side of the beam frame 2. Insertion blocks 6 are fixed to the left and right lower corners of the rear side of the curtain wall panel 1, and support blocks 5 corresponding to the insertion blocks 6 are fixed to the left and right upper corners of the rear side of the curtain wall panel 1. A notch is provided at the upper corner of one side of the back side of the support block 5, and a convex block corresponding to the notch is provided at the lower corner of one side of the back side of the insertion block 6. The curtain wall panel 1 is assembled from bottom to top. The left and right insertion blocks 6 on the lower side of the upper curtain wall panel 1 are inserted into the left and right support blocks 5 on the upper side of the lower curtain wall panel 1. The notch and the corresponding convex The setting of the block facilitates the consistent alignment of the upper and lower curtain wall panels 1, which can ensure that the upper and lower curtain wall panels 1 are more accurately connected during the installation process. The positioning of the upper and lower curtain wall panels 1 during installation is more convenient to avoid misalignment, thereby improving the installation efficiency and reducing human errors. The curtain wall panel 1 is accurately positioned and fixed on the beam frame 2 through the combination of the insert block 6 and the support block 5. The insert block 6 is located on the lower side of the curtain wall panel 1, and the support block 5 is located on the upper side of the curtain wall panel 1. In this way, the upper curtain wall panel 1 is inserted into the support block 5 on the lower curtain wall panel 1 to form a stable connection;

[0031] Furthermore, referring to Figure 4 , an upper and lower side buckle blocks 3 are arranged on one side of the rear side of the curtain wall panel 1, the side buckle blocks 3 are rotatably connected to the curtain wall panel 1, and a torsion spring is arranged at the transition of the side buckle blocks 3, and a slot block 4 corresponding to the side buckle blocks 3 is arranged on the other side of the rear side of the curtain wall panel 1. When the left and right curtain wall panels 1 are connected, the side buckle blocks 3 on one side of the newly assembled curtain wall panel 1 are pushed straight into the inner side of the currently assembled curtain wall panel 1. During this process, the side buckle blocks 3 on one side are rotated inwardly so that the side buckle blocks 3 pass through the gap between the left and right curtain wall panels 1, and then the side buckle blocks 3 are reset to their original positions by the torsion spring and are stuck on the other side of the installed curtain wall panel 1. One side corresponds to the card slot block 1 4 to achieve the positioning connection between the left and right curtain wall panels 1. Side buckle blocks 3 are set on the left and right edges of the curtain wall panel 1. These buckle blocks are connected to the curtain wall panel 1 through torsion springs and a rotating mechanism. When the newly installed curtain wall panel 1 is pushed in, the side buckle blocks 3 enter the card slot of the installed curtain wall panel 1 by rotation, so that the left and right curtain wall panels 1 are accurately docked. The side buckle blocks 3 automatically return to their original positions and snap into the card slot block 1 4 during docking through the return effect of the torsion spring, thereby achieving accurate positioning and fixation. This structure makes the splicing process not only fast but also highly adjustable, and can adapt to different construction requirements;

[0032] Furthermore, referring to Figure 4 , 5 , and the upper sides of the two plug blocks 6 are both provided with positioning plug plates 13 fixed on the curtain wall panel 1, and the left and right sides of the front side of the beam frame 2 are both provided with rotating wheels 8 corresponding to the positioning plug plates 13, the rotating wheels 8 are rotatably connected to the beam frame 2, and there is a gap between the rotating wheels 8 and the rear side beam frame 2, and the lower end of the positioning plug plate 13 is located inside the gap. In the assembly process of the upper and lower curtain wall panels 1, not only the upper and lower plug blocks 6 and the supporting blocks 5 correspond to each other, but also the positioning plug plates 13 on the left and right lower sides of the curtain wall panel 1 are inserted into the inner gaps of the left and right rotating wheels 8 corresponding to the beam frame 2, and each curtain wall panel 1 The upper plug block 6 is fixed with a positioning plug plate 13, which cooperates with the second wheel 8 on the beam frame 2. The second wheel 8 is connected to the beam frame 2 by rotation, and there is a gap between the second wheel 8 and the beam frame 2. The positioning plug plate 13 is inserted into the gap to ensure that the curtain wall panel 1 can be accurately positioned during the installation process, thereby avoiding the horizontal displacement of the curtain wall panel 1. During the assembly process of the upper and lower curtain wall panels 1, the docking mode of the plug block 6 and the support block 5 and the insertion of the positioning plug plate 13 work together to ensure that each layer of the curtain wall panel 1 can be accurately installed to form a stable structure.

[0033] Furthermore, referring to Figure 6 , 7Two clamping mechanisms 7 are arranged between the two positioning plug plates 13 on the rear side of the curtain wall panel 1. The clamping mechanism 7 includes a rotating wheel 701, which is rotatably connected to the beam frame 2. A rotating frame 702 is fixed on the rotating wheel 701. A sliding shaft 704 is arranged in the rotating frame 702. A pasting plate 703 is arranged on the upper end of the sliding shaft 704. The pasting plate 703 is flatly attached to the back of the curtain wall panel 1. Slot blocks 15 corresponding to the pasting plates 703 are arranged on the left and right sides of the rear side of the curtain wall panel 1. A linkage puzzle plate 9 is arranged between the two clamping mechanisms 7 on the rear side of the curtain wall panel 1. The linkage puzzle plate 9 slides up and down on the beam frame 2. The beam frame 2 is provided with sliding grooves corresponding to the two ends of the linkage puzzle plate 9, and the sliding grooves are provided with extrusion springs 12 corresponding to the linkage puzzle plate 9. The side of the linkage puzzle plate 9 It is in the shape of a Chinese character "bow", and sliders are arranged on the left and right sides of the rear of the linkage puzzle board 9. The linkage puzzle board 9 slides up and down on the beam frame 2 through two sliders. The pressing mechanism 7 is composed of a rotating wheel 701, a rotating frame 702, a sliding shaft 704 and a pressing plate 703. This structure ensures the close contact between the curtain wall panel 1 and the beam frame 2, thereby enhancing the energy-saving performance. The linkage puzzle board 9 realizes the close combination between the curtain wall panels 1 by sliding up and down. The slide groove and the extrusion spring 12 work together to maintain the upward movement of the linkage puzzle board 9, thereby pushing the curtain wall panel 1 to maintain close contact. The bow-shaped design of the linkage puzzle board 9 enhances its mechanical properties, making the puzzle board more stable when sliding on the beam frame 2, reducing friction and ensuring installation accuracy.

[0034] Furthermore, referring to Figure 6 , the front and rear surfaces of the rotating wheel 1 701 and the positioning plug plate 13 are both provided with tooth surfaces 14, and the left and right sides of the front side of the linkage puzzle plate 9 are both provided with rough surfaces corresponding to the tooth surfaces 14 on the rotating wheel 1 701 and the positioning plug plate 13, and the tooth surfaces 14 on the rotating wheel 1 701 and the positioning plug plate 13 are in direct contact with the rough surface on the rear side, and the front tooth surface 14 of the positioning plug plate 13 is in direct contact with the rotating wheel 2 8. After the positioning plug plate 13 is inserted into the gap between the rotating wheel 2 8 and the linkage puzzle plate 9, the linkage puzzle plate 9 is subjected to the elastic force of the extrusion spring 12, so that the linkage puzzle plate 9 rises, and then the linkage puzzle plate 9 acts on the curtain wall panel 1 through the positioning plug plate 13, so that the curtain wall panel 1 can rotate outward with the rotating wheel 2 8 as the rotation axis center, and the upper side support block 5 of the curtain wall panel 1 is pressed against The upper curtain wall panel 1 contacts the inner side of the upper curtain wall panel 1, and the lower side of the upper curtain wall panel 1 is stably fixed on the beam frame 2. Therefore, through the action of the linked splicing plate 9, the upper and lower curtain wall panels 1 can maintain close contact with each other. The rotating wheel 1 701 and the positioning plug plate 13 are both provided with tooth surfaces 14. These tooth surfaces 14 contact with the rough surface, providing greater friction, thereby enhancing the stability between the curtain wall panel 1 and the beam frame 2. This design effectively avoids possible loosening and displacement during the splicing process. The positioning plug plate 13 directly contacts the tooth surfaces 14 of the rotating wheel 1 701 and the rotating wheel 2 8, making the curtain wall panel 1 more accurate during the installation process and reducing the installation error. The tooth surface 14 provides a "locking" effect, so that each component in the splicing process can be firmly in place;

[0035] Furthermore, referring to Figure 2 , 7 , the sliding shaft 704 slides inside and outside the rotating frame 702, and a compression spring 705 corresponding to the sliding shaft 704 is arranged in the rotating frame 702, a rotating block 706 is fixed to the outer end of the sliding shaft 704, the pasting plate 703 is rotatably connected to the rotating block 706, and a torsion spring is arranged at the transition between the pasting plate 703 and the rotating block 706, and the spring force of the extrusion spring 12 is on the linkage puzzle plate 9, and the linkage puzzle plate 9 acts on the rotating wheel 1 701 through the corresponding rough surface on the inner side, so that the rotating wheel 1 701 always maintains a turning trend toward the lower outer side, and the rotating wheel 1 701 further acts on the entire pressing mechanism 7, so that the pasting plate 703 at the upper end of the pressing mechanism 7 acts stably on the rear side of the curtain wall panel 1, and Due to the spring action of the compression spring 705 in the rotating frame 702, the sliding shaft 704 always maintains an external force, the outer end of the rotating block 706 is attached to the corresponding card slot block 15, and the sliding shaft 704 slides in the rotating frame 702. Through the action of the compression spring 705, it maintains a continuous external force. This design ensures that the attaching plate 703 is always stably attached to the back of the curtain wall panel 1, and enhances stability. The rotating block 706 is connected to the attaching plate 703 and is equipped with a torsion spring, so that the attaching plate 703 can rotate freely and adhere to the back of the curtain wall panel 1. At the same time, the rotating block 706 and the compression spring 705 work together to provide a continuous external force to ensure a tight effect;

[0036] Furthermore, referring to Figure 5 , studs are fixed on the left and right outer ends of the second wheel 8, and the inner ends of the studs are sleeved with positioning blocks 10. A positioning groove corresponding to the positioning block 10 is opened on the beam frame 2, and the outer ends of the studs are threadedly connected with locking nuts 11 that are close to the surface of the positioning block 10. After the above assembly is completed, the locking nuts 11 at both ends of the second wheel 8 are rotated to make the locking nuts 11 close to the surface of the positioning block 10, so that the rotation angle of the second wheel 8 is fixed, and at the same time, the positioning plug 13 in the gap between the second wheel 8 and the linked puzzle plate 9 is fixed, so that the lower part of the curtain wall panel 1 is fixed as a whole, and in conjunction with the above-mentioned tightening mechanism 7 acting on the lower half of the curtain wall panel 1 body, its surface is on the curtain wall panel 1 The upper side has a tendency to rotate outward, so when the lower part of the upper curtain wall panel 1 is fixed, the upper part of the lower curtain wall panel 1 simultaneously maintains outward resistance to the lower part of the upper curtain wall panel 1, thereby achieving continuous stability and correlation between the upper and lower curtain wall panels 1, ensuring the rapid installation and flatness of the entire curtain wall. The function of the locking nut 11 is to fix the rotation angle of the rotating wheel 2 8, thereby ensuring that the curtain wall panel 1 will not deviate due to external interference during the installation process. The two ends of the rotating wheel 2 8 are fixed to the positioning block 10 by studs, and the locking nut 11 is used to tighten the studs to fix the rotation angle of the rotating wheel 2 8, thereby ensuring that the positioning plug plate 13 can be accurately embedded during splicing.
