Description

Technical Field

[0001] The utility model belongs to the technical field of curtain walls for building facades, and in particular to an assembled glass curtain wall with decorative wings. Background Art

[0002] According to the classification of the structural support system in the curtain wall system, the most common system types currently include the stick curtain wall system, the unitized curtain wall system, the semi-unitized curtain wall, the small unit curtain wall system, etc.

[0003] For the stick curtain wall, very few processes are completed in the factory, and most processes are carried out on-site. Therefore, the on-site material stacking is relatively messy, the material loss is relatively large, there are many on-site workers, and there are also many potential safety hazards in the construction operation, which increases the difficulty of on-site management. At the same time, the on-site workers all operate on the aerial gondolas, and the assembly accuracy between the curtain wall components is also affected to a certain extent, and the on-site construction image is also affected to a certain extent. The advantage of the unitized curtain wall is that most of its processes are completed in the factory, and there are very few on-site operation processes. The number of on-site workers is greatly reduced, the hoisting is all mechanized operation, and the operators are only engaged in indoor hoisting operation during on-site hoisting, and the overall elevation image during the construction process is also very complete.

[0004] Through the above analysis, the stick curtain wall has a low degree of factoryization, but its cost is relatively low, so it is widely used under the requirement of cost limitation; the unitized curtain wall has a high degree of factoryization and assembly, but its cost is relatively high. Therefore, there is a need to innovate a new type of curtain wall form, whose degree of factoryization and assembly is as high as that of the unitized system, while the cost is as low as that of the stick system. Therefore, the "assembled curtain wall" came into being. Content of the Utility Model

[0005] The purpose of the utility model is to provide an assembled glass curtain wall with decorative wings, whose degree of factory production and construction assembly is as high as that of the "unitized system", while the cost is as low as that of the "stick system". Thus, the "assembled system" with low cost and high quality described in this patent is realized.

[0006] In order to achieve the above purpose, the main structure of the utility model of a prefabricated glass curtain wall with decorative wings is as follows: the prefabricated glass curtain wall with decorative wings is composed of a frame system, a panel system, a decorative wing system, and a waterproof system. These four systems are assembled into independent unit panels through industrial production and processing in the factory. After being transported to the construction site, these unit panels are assembled from bottom to top in a counterclockwise order to form a curtain wall; the frame system is composed of aluminum alloy columns, aluminum alloy beams, aluminum alloy column cores, screw fasteners, and EPDM strips. The aluminum alloy columns are divided into aluminum alloy left and right columns. The columns and right aluminum alloy columns are separated. The aluminum alloy crossbeams are divided into upper, middle, and lower crossbeams. The panel system consists of glass panels, silicone structural sealant, EPDM adhesive strips, double-sided tape, aluminum alloy glass pressure plates, aluminum alloy glass supports, screw fasteners, and glass adhesive pads. The decorative wing system consists of aluminum alloy arms, aluminum alloy decorative wings, aluminum alloy decorative buckles, bolt fasteners, and screw fasteners. The aluminum alloy decorative wings are divided into vertical and horizontal aluminum alloy decorative wings. The waterproofing system consists of EPDM adhesive strips, silicone weatherproof sealant, and foam rods. The positioning of the various systems is as follows: from the outside inward, the first layer is the decorative wing system, the second layer is the panel system, and the third layer is the frame system. The waterproofing system is placed around the panel system and in the gaps between the panel system and the frame system that need to be waterproofed. The decorative wing system is connected to the frame system via aluminum alloy arms; the panel system is connected to the frame system via silicone structural sealant and aluminum alloy glass pressure plates; and the frame system is connected to the main building structural beams via connecting supports. The frame system features left and right columns and upper and lower crossbeams with specially shaped open cross-sections, and aluminum alloy column inserts installed at the tops of the left and right columns. These components are assembled into individual unit panels at the factory according to the drawings. During on-site hoisting and assembly, the aluminum alloy right column of the left adjacent unit panel is spliced and docked with the aluminum alloy left column of the right adjacent unit panel, and the aluminum alloy lower crossbeam of the upper adjacent unit panel is spliced and docked with the aluminum alloy upper crossbeam of the lower adjacent unit panel. Simultaneously, the lower end cavities of the left and right columns of the upper adjacent unit panel are inserted into the aluminum alloy column inserts of the lower adjacent unit panel. The decorative wing system features a large cross-sectional area that exceeds the maximum single-piece mold size range of the aluminum factory. To reduce mold making costs, the decorative wing is divided into two profiles with matching cross-sections. These are assembled by matching and bolting the profiles. The wing is then attached to the frame system via aluminum alloy arms, rather than being directly connected to the frame system. The waterproofing system features a silicone sealant injection method for sealing this prefabricated glass curtain wall with decorative wings, rather than the traditional "isobaric rain curtain" method used in unitized systems. This waterproofing system employs a two-stage sealing process, with the second stage completed entirely in the factory. Half of the first stage is completed in the factory, while the other half is completed on-site by injection after hoisting and assembly.

[0007] Compared with the prior art, the technical effects and advantages of this utility model are:

[0008] This prefabricated glass curtain wall with decorative wings can be factory-assembled into curtain wall units. On-site installation can be achieved through frame plug-in. The waterproofing system uses a two-layer sealing and glue injection method, which is simple and reliable. Economically, high-quality unitized prefabricated curtain walls can be achieved at a low cost similar to component-based curtain walls.

[0009] Prefabricated curtain walls are not restricted by the "component-type curtain walls" or "unit-type curtain walls." Their processing, transportation, and on-site construction methods are identical to those of unit-type curtain walls. Their cost is comparable to the lower cost of component-type curtain walls, while offering the advantages of both. Therefore, this type of prefabricated curtain wall has a wider range of applications and a brighter future for its promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present utility model. However, it will be apparent to those skilled in the art that the present utility model may be practiced without one or more of these details. In other instances, in order to avoid obscuring the present utility model, some well-known technical features are not described.

[0032] Unless otherwise defined, the directions such as up, down, left, right, front, back, inner and outer involved herein are based on the up, down, left, right, front, back, inner and outer directions in the figures shown by the present utility model, and are hereby explained together.

[0033] This embodiment discloses a prefabricated glass curtain wall with decorative wings as Figures 1 to 14 shown, which includes a frame system, a panel system, a decorative wing system and a waterproof system;

[0034] Among them;

[0035] Frame system: Aluminum alloy left column A1, aluminum alloy right column A2, aluminum alloy column core A3, aluminum alloy upper cross beam A4, aluminum alloy middle cross beam A5, aluminum alloy middle cross beam A6, aluminum alloy lower cross beam A7, screw fastener A8; Panel system: Glass panel B1, silicone structural sealant B2, EPDM strip B3, double-sided tape B4, aluminum alloy glass pressing plate B5, aluminum alloy glass support block B6, glass gasket B7, EPDM strip B8, gasket B9; Decorative wing system: Aluminum alloy support arm C1, vertical aluminum alloy decorative wing profile C2, vertical aluminum alloy decorative wing profile C3, horizontal aluminum alloy decorative wing profile C4, horizontal aluminum alloy decorative wing profile C5, aluminum alloy decorative cover C6, bolt fastener C7, bolt fastener C8, screw fastener C9; Waterproof system: Silicone weatherproof sealant D1, silicone weatherproof sealant D2, foam rod D3, EPDM strip D4, silicone weatherproof sealant D5; Connection support E1 for connecting the curtain wall to the main building structure, bolt fastener E2, main building structure beam E3.

[0036] Frame system: The frame system is the foundation, and subsequent systems are arranged and implemented on this basis. The opening of the left aluminum alloy column A1 faces left, and the opening of the right aluminum alloy column A2 faces right. The left and right columns A1 and A2 are the same length and flush in height. The characteristic is that when processing the columns, only straight cutting and drilling of process holes for screw fasteners A8 are required. There is no need to mill the lower end of the column to avoid the notch of the upper beam of the lower adjacent unit plate as in the traditional "unit curtain wall" processing method, and the processing steps are reduced; the aluminum alloy upper beam A4 is located at the upper end of the columns A1 and A2, with the profile opening facing upwards, and is fixed between the two columns A1 and A2 by screw fasteners A8. The characteristic is that the upper beam A4 only needs straight cutting and no notch is required to be milled, and the processing steps are reduced. It does not have the function of collecting rainwater or draining water; the aluminum alloy middle cross beams A5 and A6 are fixed between the two columns A1 and A2 by screw fasteners A8 according to the grid size requirements of the drawing, and the profile is a closed section; the aluminum alloy lower cross beam A7 is located at the lower end of the columns A1 and A2, with the open side of the profile facing downward and flush with the lower end surface of the column, and is fixed between the two columns A1 and A2 by screw fasteners A8; the aluminum alloy column core A3 is located at the upper end of the columns A1 and A2, half of it is cantilevered upward and half is located in the cavity, and is connected and fixed to the columns A1 and A2 by bolt fasteners E2; the connecting support E1 is also connected and fixed to the columns A1 and A2 by bolt fasteners E2 at this time. The frame system is now complete. However, considering the installation position of the aluminum alloy support arm C1 of the decorative wing system, to avoid it being covered by the glass panel B1 and unable to be installed later, the aluminum alloy support arm C1 must be pre-installed into the frame system at this stage. The installation method is to put it on the aluminum alloy left column A1, slide it along the column to the designed position, and then fix it to the left column A1 with screw fasteners C9.

[0037] Panel system: The glass panel B1 is located on the outdoor side of the frame system, and the contact surface between it and the frame system is separated by an EPDM strip B3. It is bonded and fixed to the left column A1, upper beam A4, and middle beam A6 respectively by silicone structural sealant B2; an aluminum alloy glass support block B6 and a rubber pad B9 are arranged on the outside of the beam A6 in the hidden frame, so that the weight of the glass panel can be directly transferred to the frame system, avoiding the silicone structural sealant B2 from bearing the gravity load; a glass rubber pad B7 is arranged at the contact surface between the lower beam A7 and the glass to avoid hard contact and easy breakage between the glass panel and the profile; at the left column A1 and the lower beam A7, an aluminum alloy glass pressure plate B5 is arranged on the outer surface of the glass panel B1 to press the glass panel, and the glass panel and the aluminum alloy glass pressure plate are separated by EPDM strip B8 to avoid hard contact and easy breakage.

[0038] Before installing the decorative wing system into the frame system, the vertical aluminum alloy decorative wing profiles C2 and C3 are first joined together, their cross-sectional construction ensuring they engage. Bolt fasteners C8 are then secured in the upper and lower cavities of the profiles, restricting the vertical and horizontal sliding of the two matching decorative wing profiles C2 and C3. This completes the vertical decorative wing assembly. Similarly, the horizontal aluminum alloy decorative wing profiles C4 and C5 are joined together, and bolt fasteners C8 are secured in the left and right cavities of the profiles, completing the horizontal decorative wing assembly. The vertical and horizontal decorative wing assemblies are then secured to the pre-installed decorative wing support arms C1 on the left upright column A1 and lower crossbeam A7, respectively, using bolt fasteners C7. Finally, the aluminum alloy decorative buckle covers C6 are fastened to the sides of the decorative wing profiles C2 and C4.

[0039] Waterproofing system: This system utilizes a reliable two-line "glue injection" waterproofing method. D01 is completed with silicone weatherproof sealants D1 and D5. Sealant D1 is factory-injected along the contact surface gap between the aluminum alloy glass pressure plate B5 and the glass panel B1, while D5 is uniformly injected and sealed after the unit panels are hoisted and assembled on-site. D02 is completed with D2, D3, and D4, and is completed entirely during the assembly of the unit panels in the factory, reducing on-site construction steps. Specifically, after glass panel B1 is assembled, foam rod D3 is inserted into the side gap between B1 and A1 and A7. Silicone weatherproof sealant D2 is then injected along this gap and cured to form. EPDM strip D4 is directly pressed into the side structural cavity of profiles A1 and A7. After the curtain wall is assembled on-site, it collides and squeezes with the glass side of the adjacent panels to form a waterproof seal.

[0040] At this point, a complete set of prefabricated glass curtain wall unit panels with decorative wings has been processed and assembled in the factory. After being transported to the project site by truck, they are hoisted and assembled one by one in the counterclockwise order from left to right and from bottom to top according to the facade numbering diagram to form the patented prefabricated glass curtain wall with decorative wings.
