Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, specifically to an integrated, modular splicing curtain wall structure. Background Technology

[0002] A curtain wall is a building envelope or decorative structure, consisting of a supporting structural system and panels. The supporting structural system mainly includes the truss, which is used to fix the panels and transfer loads to the main structure. Common panel materials include glass, metal plates (such as aluminum plates), stone, and artificial panels (such as aluminum composite panels and terracotta panels), which directly determine the appearance and function of the curtain wall (such as light transmission and thermal insulation).

[0003] The existing curtain wall keel is generally made of aluminum alloy profiles. During the processing, aluminum alloy profiles need to be ordered from aluminum alloy profile manufacturers (the aluminum alloy profile manufacturers need to purchase aluminum ingots, then produce shaped aluminum rods, then produce extruded molding, and then insert thermal insulation strips to form aluminum alloy profiles). Then the purchased profiles are cut, milled, drilled and other processed, and then the processed parts are assembled into a frame. This process has a long production cycle, many production steps, a lot of material waste, low precision of finished products, poor aesthetics of finished products, and is prone to water leakage problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides an integrated modular splicing curtain wall structure to solve the problems of long production cycle, many production steps, material waste, low precision of finished products, poor aesthetics of finished products, and easy leakage of existing curtain walls.

[0005] The present invention provides an integrally molded unitized splicing curtain wall structure, which is composed of several curtain wall units spliced ​​together. Each curtain wall unit includes an integrally die-cast keel and a panel disposed on the outside of the keel.

Detailed Implementation

[0019] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0021] like Figures 1-7 As shown, this embodiment of the invention provides an integrated modular splicing curtain wall structure, which is composed of several curtain wall units 100 spliced ​​together.

[0022] The curtain wall unit 100 includes an integrally die-cast keel 110 and a panel 120 disposed on the outside of the keel 110. The keel 110 has an outer frame 210, and the outer frames 210 of the keels 110 of two adjacent curtain wall units 100 are interlocked.

[0023] In this embodiment, the keel 110 is specifically made of aluminum alloy.

[0024] In this embodiment, panel 120 is specifically a double-layered insulated glass.

[0025] The processing flow in this embodiment is as follows: 1. Melt the heat-free aluminum alloy ingot and maintain it at approximately 660℃; 2. Inject the molten aluminum into a dedicated mold cavity through a large vacuum die-casting machine for 120 seconds, then solidify and cool; 3. After forming, remove the ingot, trim the edges, and correct the mold; 4. Inspect for cracks and defects using blue light; 5. Anodize the ingot; 6. Apply a surface coating; 7. Insert the keel into a dedicated mold, and inject heat-insulating adhesive under high pressure at 26℃ for 30 seconds until it solidifies; 8. Install the curtain wall glass; 9. Conduct overall quality inspection; 10. Packaging.

[0026] During die casting, the aluminum alloy ingot is first melted and maintained at approximately 660℃. Then, the molten aluminum is injected into a special mold cavity through a large vacuum die casting machine for 120 seconds to form and solidify. 3. After forming, the mold is removed, trimmed, and corrected. The main keel and secondary keel are die-cast as a whole, improving overall strength and eliminating the risk of water leakage. 4. Because the integrated die casting eliminates the need for connectors at all connections between the main keel and secondary keel, the current curtain wall production is compared with our company's invention patent (see comparison diagram). 6. Blue light inspection is performed to check for cracks and defects. 7. Thermal insulation strip reinforcement groove milling. 8. Anodizing. 9. Surface spraying treatment. 10. The main keel and secondary keel enter the special mold, and the thermal insulation adhesive is injected under high pressure and solidifies in a 26℃ environment for 30 seconds. The thermal insulation strip solidifies (see diagram), forming a complete curtain wall unit. 11. Installation of curtain wall glass. 12. Overall quality inspection. 18. Packaging.

[0027] In this embodiment, refer to Figure 3 and Figure 4 The two outer frames 210 of two adjacent curtain wall units 100 are connected to each other, and their sides are the first frame and the second frame, respectively. The first frame and the second frame are groove-shaped structures with opposite slots.

[0028] The first frame has slots 211 on both sides of its two groove walls, and the second frame has strips 212 on both sides of its two groove walls. Each strip 212 has a first adhesive strip 213 at its end, which is inserted into each slot 211. Alternatively, the first and second frame have slots 211 on both sides of one groove wall of the first frame and one groove wall of the second frame, and strips 212 on both sides of the other groove wall of the first frame and the other groove wall of the second frame. Each strip 212 has a first adhesive strip 213 at its end, which is inserted into each slot 211.

[0029] When splicing curtain wall units 100, the clip 212 with the first adhesive strip 213 on the side keel 110 of one curtain wall unit 100 can be inserted into the slot 211 on the side keel 110 of another curtain wall unit 100. The two frames after splicing form a sealed hollow structure, which can prevent water from entering. At the same time, after splicing, its exterior has a columnar structure, which fits perfectly and has an aesthetically pleasing appearance.

[0030] In this embodiment, refer to Figure 3 and Figure 4Each side of the outer frame 210 is provided with a first stop bar 220 extending forward, which is used to limit the side of the panel 120.

[0031] In this embodiment, we continue to refer to... Figure 3 and Figure 4 A first foam strip 230 is provided between the side of the panel 120 and the corresponding first baffle 220. The first foam strip 230 can play a buffer and anti-collision role between the panel 120 and the first baffle 220. The panel 120 is pasted to the outside of each side of the outer frame 210 by the first double-sided adhesive 240. A first sealant 250 is provided at the angle between the panel 120 and the outer frame 210. A second sealant 260 is provided between the panel 120 and the first baffle 220 on the outside of the first foam strip 230. This design can achieve a sealed connection between the side of the panel 120 and the outer frame 210.

[0032] Preferably, refer to Figure 3 Each curtain wall unit 100 has a first cover 270 on the outside of the vertical joint. The two sides of the first cover 270 are supported on the outside of the panels 120 on both sides of the vertical joint by second adhesive strips 271. The inside of the first cover 270 has a first T-shaped groove 272. One of the two first baffles 220 at the vertical joint has a first T-shaped head 221 that engages with the first T-shaped groove 272. During assembly, the first T-shaped groove 272 on the inside of the first cover 270 is engaged with the first T-shaped head 221 at the outside of the first baffle 220 at the vertical joint. The two sides of the first cover 270 are supported on the outside of the panels 120 on both sides of the vertical joint by the second adhesive strips 271. This can limit the position of the panels 120 and prevent the panels 120 from falling off the keel 110.

[0033] In this embodiment, refer to Figure 5 The keel 110 has several horizontally arranged middle horizontal frames 310 within the outer frame 210. The outer side of the middle horizontal frame 310 is provided with a forward-extending second baffle 320. The panel 120 is separated from the second baffle 320 of each middle horizontal frame 310. A second foam strip 330 is provided between the second baffle 320 and the side edges of the panel 120 on both sides. The panel 120 is pasted to the outer side of the middle horizontal frame 310 by a second double-sided adhesive 340. A third sealant 350 is provided at the angle between the panel 120 and the middle horizontal frame 310. A fourth sealant 360 is provided between the panel 120 and the second baffle 320 on the outer side of the second foam strip 330.

[0034] In this embodiment, the outer frame 210 serves as the main keel, while the middle horizontal frame 310 is set inside the outer frame 210 as the secondary keel. This not only improves the overall strength of the keel 110, but also meets the requirement of vertically dividing and installing the panel 120, thus reducing the size of a single panel 120.

[0035] When the width of a single curtain wall unit 100 is large, a central column can be set inside the outer frame 210.

[0036] In one embodiment, referring to 6, the keel 110 has a plurality of first central columns 410 arranged vertically within the outer frame 210. The panel 120 is pasted to the outside of the first central columns 410 by a third double-sided adhesive 420. A fifth sealant 430 is provided at the angle between the panel 120 and the first central column 410. The first central column 410 only serves to support the panel 120.

[0037] In another embodiment, reference Figure 7 The keel 110 has several second central posts 510 arranged vertically within the outer frame 210. The outer side of the second central posts 510 is provided with a forward-extending third baffle 520. The panel 120 is separated from each second central post 510 by the third baffle 520. A third foam strip 530 is provided between the third baffle 520 and the sides of the panel 120 on both sides. The panel 120 is pasted to the outer side of the second central posts 510 by a fourth double-sided adhesive 540. A sixth sealant 550 is provided at the angle between the panel 120 and the second central posts 510. A seventh sealant 560 is provided between the panel 120 and the second baffle 520 on the outer side of the third foam strip 530. The second central posts 510 serve to divide and install the panel 120.

[0038] Preferably, each second central column 510 is provided with a second cover 570 on its outer side. The two sides of the second cover 570 are supported by a third adhesive strip 571 on the outer side of the panel 120 on both sides of the second central column 510. The inner side of the second cover 570 is provided with a second T-shaped slot 572. The outer end of the third baffle 520 is provided with a second T-shaped head 521 that engages with the second T-shaped slot 572. The second cover 570 can limit the panel 120 and prevent the panel 120 from falling off the keel 110.

[0039] In this embodiment, hooks 600 are provided on both sides of the inner side of the upper part of the keel 110 of each curtain wall unit 100. The hooks 600 are used to hang the curtain wall unit 100 on the outside of the building body when installing the curtain wall.

[0040] For locations where windows are required in the curtain wall, this embodiment allows windows to be directly installed on the corresponding curtain wall unit 100. During installation, the curtain wall unit 100 with integrated windows can be spliced ​​at the corresponding location.

[0041] The performance comparison of the curtain wall structure of the present invention with that of traditional curtain walls and conventional unitized curtain walls is as follows:

[0042] Compared with existing curtain wall structures, this invention has at least the following advantages: (1) Since there is no corner assembly link, the risk of water leakage in the production and installation links is solved; (2) The production cycle is greatly shortened, eliminating the aluminum rod production link, extrusion production link, and corner assembly production link of main keel and secondary keel; (3) It solves the problems of poor aesthetics of the size of the gap in the assembly of the main keel and secondary keel connectors and the height difference of the gap, and the aesthetics are significantly improved; (4) Due to the integral casting molding, the compressive strength, yield strength, wind pressure resistance, sound insulation, and thermal insulation performance are significantly improved; (5) Since the error of the same specification curtain wall type is almost zero in one molding, the production error standard of the product is more than 100% higher than the national standard; (6) The product has good consistency and interchangeability, and no aluminum alloy waste is generated.

[0043] In summary, the keel 110 of the curtain wall unit 100 of the present invention adopts an integrated die-casting process, which reduces the use of aluminum alloy materials by more than 30%, and has the advantages of high production efficiency and high product precision. Unlike traditional processes, the product has no seams, making it more aesthetically pleasing and avoiding water leakage at the splice. At the same time, the compressive strength, yield strength, wind pressure resistance, sound insulation, and thermal insulation performance are significantly improved. The entire production process of the keel 110 of the curtain wall unit 100 can realize fully intelligent production, which can reduce material waste and wastewater and exhaust gas emissions.
