Technical Field

[0001] This invention relates to a modular suspension system for eaves structure curtain walls, belonging to the field of building curtain wall technology. Background Technology

[0002] With the continuous development of my country's construction industry, modern buildings are gradually moving towards more complex forms and green construction methods, while still meeting functional requirements. Prefabricated curtain walls, with their advantages of high construction efficiency, environmental friendliness, and energy conservation, have developed rapidly under policy support and technological innovation, and are now widely used in projects such as super high-rise buildings, rail transit hubs, and large commercial complexes. However, in practical applications, prefabricated curtain walls still face many technical challenges, especially in structures with complex shapes and overhanging eaves. The cantilevered eaves divide the building outline by floor, placing high demands on the design, installation, and performance of prefabricated curtain walls. This also provides an opportunity for the development of modular prefabricated systems for complex building structures.

[0003] Currently, the main problems in this field are as follows: insufficient control of construction precision, which easily leads to misalignment of the connection points between the curtain wall keel and the main structure; the traditional frame system has a large reaction force on the main structure and a weak resistance to planar deformation; it is difficult to achieve effective integration of modular assembly systems; and construction efficiency is low due to installation space limitations. These problems directly affect the efficiency of engineering construction, construction quality, and green and sustainable development. Therefore, new solutions are needed to address these issues. Summary of the Invention

[0029] As attached Figure 1 As shown, the modular suspension system of the eaves structure curtain wall of the present invention includes an eaves body 1, a curtain wall panel 2 and an edge panel 5.

[0030] The upper and lower sides of the eaves body 1 are respectively fixedly provided with a first positioning connector 11 and a second positioning connector 12 that are symmetrical to each other. The first positioning connector 11 and the second positioning connector 12 are fixed to the eaves body 1 by means of bolt connection or welding.

[0031] The curtain wall panel 2 includes an upper horizontal beam, a lower horizontal beam 22, a column 23, and a glass panel 24; wherein, the upper horizontal beam and the lower horizontal beam 22 are respectively connected and fixed to the upper and lower sides of the column 23, and the upper and lower ends of the glass panel 24 are respectively installed on the upper horizontal beam and the lower horizontal beam 22 to form an integral modular curtain wall panel 2; in this embodiment, the upper horizontal beam, the lower horizontal beam 22, and the column 23 are all made of aluminum alloy profiles.

[0032] As attached Figure 2-3As shown, specifically, the upper crossbeam includes a strip baffle 211, a main profile 212, and an arched cantilever 213. Both the strip baffle 211 and the arched cantilever 213 are mounted on the second positioning connector 12. In this embodiment, the inner side of the arched cantilever 213 is provided with a concave slot 2131, and the second positioning connector 12 is provided with a serrated bracket 121. The serrated bracket 121 and the strip baffle 211 are fixed together on the second positioning connector 12 by bolts. The bottom of the serrated bracket 121 has a locking block 1211 that matches the concave slot 2131. The locking block 1211 of the serrated bracket 121 is engaged in the concave slot 2131 of the arched cantilever 213, and a fastening screw 6 is driven into the engagement position to lock the serrated bracket 121 and the arched cantilever 213 together to prevent the serrated bracket 121 from shifting horizontally.

[0033] The main profile 212 is connected and fixed to the upper side of the column 23 by a commonly used insert structure in the art. The main profile 212 is connected and fixed to the strip baffle 211 by a Z-shaped connector 3. In this embodiment, the Z-shaped connector 3 is arranged vertically, and its two ends are connected to the strip baffle 211 and the main profile 212 by screws respectively. The outer side of the main profile 212 is sealed to the outer side of the arched cantilever 213. The outer side of the main profile 212 and the outer side of the arched cantilever 213 are sealed with EPDM rubber strip to ensure the sealing between the two.

[0034] Furthermore, a correction pad 7 is provided between the strip baffle 211 and the second positioning connector 12. The correction pad 7 is used to compensate for the installation gap between the strip baffle 211 and the second positioning connector 12, correct the installation level and verticality of the strip baffle 211, and ensure the connection accuracy between the strip baffle 211 and the arched cantilever 213 and the main profile 212.

[0035] Furthermore, the arched cantilever 213 gradually curves upward from the indoor side to the outdoor side. The curved structure of the arched cantilever 213 profile is used to offset the deformation of the panels under structural deformation and wind load, maintain the horizontal flatness of the inter-floor panels, and thus enhance the aesthetics of the building.

[0036] During installation, the upper beam can be disassembled into three parts for separate installation. First, the strip baffle 211 profile is installed as a connecting component. At this time, the space at the top of the column 23 can be used to hoist the panels. Then, the main profile 212 is installed on the upper side of the column 23 and temporarily fixed with Z-type connectors 3. Finally, the arched cantilever 213 is installed using a snap-fit ​​structure. By adopting this split installation method, the problem of low application of prefabricated structures in eaves structures is effectively solved, the available working space for hoisting the panels at the top is increased, and the construction difficulty is reduced.

[0037] Furthermore, a sealing bushing 231 is provided at the top of the column 23. The sealing bushing 231 is located above the main body profile 212. In this embodiment, the sealing bushing 231 is made of rubber. It is fitted on the top of the column 23 to seal the column 23 profile, so as to prevent rainwater, dust and other substances from seeping in, while reducing heat transfer and improving heat insulation performance.

[0038] As attached Figure 4-5 As shown, the lower crossbeam 22 is connected and fixed to the lower side of the column 23. The connection between the lower crossbeam 22 and the lower side of the column 23 adopts a commonly used insert structure in the art. A pedestal positioning base 4 is fixedly provided at the bottom of the lower crossbeam 22. The positioning base is installed on the first positioning connector 11. In this embodiment, the pedestal positioning base 4 and the lower crossbeam 22 are fixed by an insert structure. A water trough 8 is provided between the pedestal positioning base 4 and the lower crossbeam 22. In this embodiment, the water trough 8 is provided along the length of the lower crossbeam 22, which can collect a small amount of rainwater entering the curtain wall in time and discharge it through the preset drainage hole, thereby improving the waterproof performance of the curtain wall and avoiding component corrosion caused by rainwater accumulation.

[0039] The top of the first positioning connector 11 is fixedly provided with a bottoming profile 111, wherein the bottoming profile 111 is fixed to the first positioning connector 11 by bolts, and both sides of the bottoming profile 111 have slots 1111. The bottom of the upright positioning base 4 is engaged in the slots 1111 of the bottoming profile 111 and presses the bottoming profile 111 tightly.

[0040] The upper and lower ends of the glass panel 24 are respectively installed on the main body profile 212 and the upright positioning base 4. In this embodiment, the glass panel 24 is fixed to the main body profile 212 and the upright positioning base 4 by structural adhesive and double-sided adhesive commonly used in the art, thus completing the installation of the curtain wall panel 2.

[0041] By setting a second positioning connector 12 and a hanging structure that cooperates with the upper horizontal beam at the upper opening of the curtain wall panel 2, and setting a seated positioning base 4 and a base profile 111 that cooperates with the lower opening of the curtain wall panel 2, the hanging structure bears 60% of the vertical load of the panel, and the seated pressure-bearing structure bears 40% of the horizontal load of the panel, the safety factor of the entire system structure is effectively improved, and the wind pressure resistance of the overall system is enhanced.

[0042] As attached Figure 1-5 As shown, the upper and lower ends of the edging plate 5 are connected to the bottom and top of the curtain wall plate 2, respectively, to cover the outer end of the eaves body 1.

[0043] Specifically, the edging panel 5 includes an edging keel 51 and an edging aluminum plate 52. The edging keel 51 is made of galvanized steel keel. The edging keel 51 is set around the eaves body 1 and fixed to the eaves body 1 with bolts. The edging aluminum plate 52 is fixed to the outside of the edging keel 51 by multiple connecting brackets 9.

[0044] Furthermore, the top of the edging aluminum plate 52 is fixed to the outer end of the upright positioning base 4 with screws, and foam rods and sealant are applied at the fixing position; the bottom of the edging aluminum plate 52 is connected and fixed to the outer end of the arched cantilever 213, and foam rods and sealant are applied at the fixing position; the foam rods can fill the gap between the edging aluminum plate 52 and the upright positioning base 4 and the arched cantilever 213, and the sealant further seals, ensuring a seamless connection between the edging panel 5 and the curtain wall panel 2. This not only improves the overall appearance of the building, but also effectively prevents rainwater and dust from entering, further improving the waterproof and dustproof performance of the curtain wall, while enhancing the structural integrity of the entire system.
