Abstract
Description
Technical Field
[0001] This invention relates to a prefabricated, large-span, detachable, stepped curtain wall system for interior use, belonging to the field of building curtain wall technology. Background Technology
[0002] Modern architectural design pursues personalization and diversity, placing higher demands on the aesthetics, functionality, and environmental friendliness of building facades. Simultaneously, with the continuous development of my country's construction industry, new construction methods such as green buildings, prefabricated buildings, and intelligent buildings are receiving increasing attention. Currently, conventional glass curtain walls often rely on concrete support structures to achieve their facade effects. However, the inherent limitation of conventional concrete support structures in terms of their ability to freely expand their shapes conversely restricts the building facade's appearance, resulting in curtain walls that often appear very similar. Furthermore, conventional steel structure curtain wall systems often employ on-site welding for frame connections. Their heavy weight and the significant amount of high-altitude welding work often lead to low construction efficiency, difficulty in quality control, and substantial safety hazards. Summary of the Invention
[0003] To address the aforementioned technical problems, the objective of this invention is to propose a prefabricated, large-span, detachable, stepped curtain wall system for indoor use.
[0004] The technical solution of the present invention is implemented as follows: a prefabricated large-span indoor detachable stepped curtain wall system, comprising a building steel structure, stepped units and ventilation components;
[0005] The stepped unit includes columns, upper crossbeams, middle crossbeams, lower crossbeams, glass panels, and honeycomb aluminum panels. The columns have a continuous L-shaped bending structure. The upper and middle crossbeams are both connected and fixed to the inner side of the bend in the column, and are also connected and fixed to the building steel structure. The lower crossbeam is connected and fixed to the outer side of the bend in the column. The outer ends of the upper crossbeams are fixed with a first upper support and a second upper support. The outer ends of the middle crossbeams are fixed with a middle support. The outer ends of the lower crossbeams are fixed with a lower support. The glass panels and honeycomb panels are inclined. The upper and lower ends of the glass panels are fixed to the first upper support and the lower support, respectively. The upper and lower ends of the honeycomb aluminum panels are fixed to the middle support and the second upper support, respectively.
[0006] The ventilation assembly is horizontally arranged, with its inner and outer ends fixed to the ends of the middle support and the lower support, respectively.
[0007] Preferably, a dividing steel strip is fixedly installed in the middle of the building steel structure, and the middle crossbeam is fixed on the dividing steel strip; a transition piece is provided on the upper crossbeam, and the upper crossbeam is fixed to the building steel structure through the transition piece.
[0008] Preferably, aluminum panels are fixedly installed around the perimeter of the building steel structure, and the aluminum panels cover the building steel structure.
[0009] Preferably, the first upper support and the second upper support are fixed to the end of the upper crossbeam by bolts, the middle support is fixed to the end of the middle crossbeam by bolts, and the lower support is fixed to the lower crossbeam by bolts; the two ends of the glass panel are fixed to the first upper support and the lower support respectively by silicone structural adhesive, and the two ends of the honeycomb aluminum plate are fixedly provided with first connectors, and the two ends of the honeycomb aluminum plate are fixed to the middle support and the second upper support respectively by the first connectors.
[0010] Preferably, the ventilation assembly includes an aluminum alloy grille, a stainless steel insect net, and a second connector. There are two second connectors. The aluminum alloy grille and the stainless steel insect net are parallel to each other, with the aluminum alloy grille located outside the stainless steel insect net. The two ends of the aluminum alloy grille and the stainless steel insect net are respectively fixed to the two second connectors, which are respectively fixed to the middle support and the lower support.
[0011] Preferably, sealant and foam rods are applied between the lower end of the honeycomb aluminum plate and the upper end of the glass panel, and between the lower end of the glass panel and the second connector.
[0012] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:
[0013] 1. This invention adopts a modular design of stepped units. The assembly of the stepped units is carried out in a standardized and large-scale production process in the factory, which effectively ensures the assembly accuracy of the stepped units. The stepped units adopt an indoor loading and unloading installation method, which reduces the risk of outdoor high-altitude operations, improves construction safety, simplifies maintenance procedures, and improves maintenance efficiency.
[0014] 2. By using an aluminum alloy grille and stainless steel insect net ventilation structure at the entrance and exit of the stepped curtain wall, a natural ventilation system is formed for the building, which reduces the dependence on artificial heat and cold sources, reduces building energy consumption, thereby reducing fossil energy consumption and greenhouse gas emissions, and prevents building material corrosion and decorative surface damage caused by excessive indoor humidity, thus extending the service life of building structure and decoration materials.

For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.
[0024] As attached Figure 1 As shown, the prefabricated large-span indoor detachable stepped curtain wall system of the present invention includes a building steel structure 1, stepped units and ventilation components. The building steel structure 1 serves as the load-bearing foundation of the entire curtain wall system and is made of high-strength steel. Compared with conventional concrete support structures, it is lighter and stronger, and can easily adapt to the support requirements of large-span indoor spaces.
[0025] The stepped unit includes a column 21, an upper crossbeam 22, a middle crossbeam 23, a lower crossbeam 24, a glass panel 25, and a honeycomb aluminum panel 26; in this embodiment, the column 21, the upper crossbeam 22, the middle crossbeam 23, and the lower crossbeam 24 are all made of galvanized steel pipes.
[0026] The column 21 has a continuous L-shaped bending structure, which can accurately adapt to the installation requirements of the stepped shape without the need for additional connecting structures, making the step transition more natural and smooth. The upper crossbeam 22 and the middle crossbeam 23 are both connected and fixed to the inner side of the bend of the column 21, and the upper crossbeam 22 and the middle crossbeam 23 are both connected and fixed to the building steel structure 1. The lower crossbeam 24 is connected and fixed to the outer side of the bend of the column 21. In this embodiment, a dividing steel strip 11 is fixedly installed in the middle of the building steel structure 1, and the middle crossbeam 23 is directly fixed to the dividing steel strip 11 by welding. A connecting piece 223 is provided on the upper crossbeam 22, and the upper crossbeam 22 is fixed to the building steel structure 1 through the connecting piece 223. The material of the connecting piece 223 is the same as that of the upper crossbeam 22, and the two ends of the connecting piece 223 are connected and fixed to the upper crossbeam 22 and the building steel structure 1 by welding.
[0027] As attached Figure 1-4 As shown, the outer end of the upper crossbeam 22 is fixedly provided with a first upper support 221 and a second upper support 222, the outer end of the middle crossbeam 23 is fixedly provided with a middle support 231, and the outer end of the lower crossbeam 24 is fixedly provided with a lower support 241. The first upper support 221 and the second upper support 222 are fixed to the end of the upper crossbeam 22 by bolts, the middle support 231 is fixed to the end of the middle crossbeam 23 by bolts, and the lower support 241 is fixed to the lower crossbeam 24 by bolts.
[0028] In this embodiment, the first upper support 221, the second upper support 222, the middle support 231 and the lower support 241 are all made of aluminum alloy profiles.
[0029] Both the glass panel 25 and the honeycomb are inclined. The upper and lower ends of the glass panel 25 are fixed to the first upper support 221 and the lower support 241, respectively. The upper and lower ends of the honeycomb aluminum plate 26 are fixed to the middle support 231 and the second upper support 222, respectively. In this embodiment, the two ends of the glass panel 25 are fixed to the first upper support 221 and the lower support 241, respectively, by silicone structural adhesive 4. The two ends of the honeycomb aluminum plate 26 are fixed with the first connector 261, and the two ends of the honeycomb aluminum plate 26 are fixed to the middle support 231 and the second upper support 222, respectively, by the first connector 261.
[0030] The honeycomb aluminum panel 26 is lightweight, high-strength, and has excellent sound and heat insulation performance. It can not only make up for the lack of sound and heat insulation of the glass panel 25, but also enrich the material layers of the curtain wall and improve the comfort of the interior space.
[0031] Furthermore, sealant and foam rods 5 are applied between the lower end of the honeycomb aluminum panel 26 and the upper end of the glass panel 25, and between the lower end of the glass panel 25 and the second connector 33. The foam rods can fill the gaps and buffer and dampen the shock, while the sealant can completely seal the gaps, thereby effectively preventing rainwater, dust and noise from entering the room, improving the airtightness and comfort of the indoor space, and avoiding problems such as condensation and mold at the gaps, thus extending the service life of the curtain wall system.
[0032] The ventilation assembly is horizontally arranged, with its inner and outer ends fixed to the ends of the middle support 231 and the lower support 241, respectively. Specifically, the ventilation assembly includes an aluminum alloy grille 31, a stainless steel insect net 32, and two connecting pieces 33. The aluminum alloy grille 31 and the stainless steel insect net 32 are parallel to each other, with the aluminum alloy grille 31 located outside the stainless steel insect net 32. The ends of the aluminum alloy grille 31 and the stainless steel insect net 32 are fixed to the two connecting pieces 33 by screws, and the two connecting pieces 33 are fixed to the middle support 231 and the lower support 241 by screws.
[0033] The aluminum alloy grille 31 not only has good ventilation performance, but also serves a decorative purpose, matching the overall shape of the curtain wall, while also preventing large debris from entering the room; the stainless steel insect net 32 can effectively block mosquitoes from entering, ensuring the cleanliness of the indoor environment. By placing both at the entrance and exit of the stepped curtain wall, the ventilation function is achieved, the building's energy-saving requirements are met, and practicality and aesthetics are taken into account.
[0034] Furthermore, aluminum panels 12 are fixedly installed around the steel structure 1 of the building. The aluminum panels 12 cover the steel structure 1 of the building. On the one hand, the aluminum panels 12 protect the steel structure 1 of the building from corrosion and dust, extending the service life of the steel structure. On the other hand, they make the appearance of the curtain wall system more neat and uniform, improve the overall aesthetic effect, and prevent the exposed steel structure from affecting the indoor visual experience.
[0035] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
