Description

Technical Field

[0001] This utility model belongs to the field of glass curtain wall technology, specifically relating to an installation structure for inclined curved glass curtain walls. Background Technology

[0002] With the continuous development of modern building technology, glass curtain walls, as an aesthetically pleasing and efficient building envelope, are widely used in various high-rise buildings and large public facilities. Glass curtain walls not only provide excellent lighting but also enhance the building's appearance and energy efficiency. However, with increasingly complex architectural designs, traditional vertical glass curtain walls can no longer meet the diverse shapes and functions required by modern buildings, leading to the frequent emergence of curved glass curtain walls, inclined glass curtain walls, and other designs in architectural forms.

[0003] Curved glass curtain walls are typically constructed by splicing together multiple flat glass panels. By designing the angles and positions of these panels, the overall effect of the curtain wall can be a continuous curved surface. Compared to custom-producing large pieces of curved glass, using flat glass to create a curved surface can reduce production costs. However, to construct the curved surface, the curtain wall often needs to be installed at an angle. Compared to vertically installed glass curtain walls, angled installations typically need to withstand greater wind loads and self-weight loads, while also requiring consideration of the sealing performance and fire resistance between the glass and the supporting structure. Currently, for example, only double-sided adhesive and structural adhesive are typically used between the glass curtain wall and the horizontal beams (horizontal keels). However, after prolonged exposure to direct sunlight, these adhesives may experience inadequate sealing and aging cracking.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] like Figures 1 to 2 As shown, an inclined curved glass curtain wall installation structure includes a glass curtain wall 100, a first channel steel 5, a second channel steel 10 with a length greater than that of the first channel steel 5, and a column 16. The first channel steel 5 and the second channel steel 10 are respectively fixed to the side of the floor slab 200 by embedded parts 1, with the second channel steel 10 located directly below the first channel steel 5. The column 16 is inclinedly installed on the side of the first channel steel 5 and the second channel steel 10. An aluminum alloy beam 15 is installed on the column 16, and a sub-frame 17, a side seal 18, an aluminum alloy support strip 20, and a pressure plate 19 are installed on the aluminum alloy beam 15. The pressure plate 19 presses and fixes the sub-frame 17 to the aluminum alloy beam 15. Structural adhesive 24 and double-sided adhesive are provided between the sub-frame 17 and the glass curtain wall 100. The surface adhesive strip 23 is used, and the distance between the sub-frame 17 and the glass curtain wall 100 is 8mm. The structural adhesive 24 is generally made of silicone structural sealant. The edge seal 18 is located outside the sub-frame 17, and the outer surface of the edge seal 18 is flush with the outer surface of the aluminum alloy beam 15 for a more aesthetically pleasing appearance. The end of the edge seal 18 facing the glass curtain wall 100 is provided with a glue-holding groove, and the distance between the glue-holding groove and the inside of the glass curtain wall 100 is 6mm-7mm. A hollow adhesive strip 25 is installed in the glue-holding groove. The hollow adhesive strip 25 can be made of EPDM rubber strip, and the hollow adhesive strip 25 abuts against the inner side of the glass curtain wall 100. The bottom of the glass curtain wall 100 is supported by an aluminum alloy support plate. A rubber pad 21 is placed between the aluminum alloy support plate and the glass curtain wall 100.

[0028] Furthermore, such as Figure 1 , Figure 2As shown, two first slots are provided on the outdoor-facing end face of the aluminum alloy beam 15, with the first slots located near the upper and lower sides of the beam 15. Each first slot has a raised first latch at its opening, and the two sealing edges located at the top and bottom are respectively fixed in the first slot by latching claws. A second slot is provided in the middle of the outdoor-facing end face of the aluminum alloy beam 15, with a raised second latch at its opening. The inner end of the aluminum alloy support strip 20 has a hook and abutment. The hook of the support strip 20 extends into the second slot and hooks onto the inner side of the second latch, while the abutment abuts against the outer side of the second latch. The center of the pressure plate 19 is installed in the second slot using an M6×25 cross-slot pan head bolt assembly.

[0029] Furthermore, such as Figure 1 , Figure 2 As shown, an inner rubber strip 26, which is a solid EPDM rubber strip, is provided between the sub-frame 17 and the aluminum alloy crossbeam 15. The inner rubber strip 26 prevents the sub-frame 17 from directly contacting the aluminum alloy crossbeam 15 and plays a buffering role.

[0030] Furthermore, such as Figure 1 , Figure 2 As shown, an oblong hole is made on column 16 (for example, the size of the oblong hole is...). The column 16 can be fixed to the first channel steel 5 and the second channel steel 10 using M12×135 stainless steel bolts 6. The left and right widths of the sub-frame 17 and the side seal 18 are adjusted according to the thickness of the glass curtain wall 100, such as... Figure 2 In the middle, the upper glass curtain wall 100 is thicker, and the left and right widths of the sub-frame 17 and the side seal 18 are adjusted accordingly, so that the left and right widths of the upper sub-frame 17 and the side seal 18 are smaller than those of the lower sub-frame 17 and the side seal 18.

[0031] Furthermore, such as Figure 1 As shown, an expansion joint of 19mm-21mm is reserved between two adjacent vertical columns 16, and the expansion joint is filled with silicone weather-resistant sealant 11. The space between two adjacent vertical glass curtain walls 100 is filled with sealant (silicone weather-resistant sealant) and a foam rod 22 with a diameter of 16mm.

[0032] Furthermore, such as Figure 1As shown, a sealing beam 12 is installed on the column 16 above the first channel steel 5. The sealing beam 12 is higher than the upper surface of the floor slab 200, and a cover steel plate 13 connects the sealing beam 12 and the upper surface of the floor slab 200. The sealing beam 12 is abutted against the glass curtain wall 100 by an adhesive strip, which is an EPDM rubber strip. The gap between the glass curtain wall 100 and the column 16 is sealed with sealant to increase airtightness, sound insulation, waterproofing, and anti-shaking. The lower end of the sealant sealing is at the adhesive strip. The aluminum alloy beam 15 is located below the lower surface of the floor slab 200. A first supporting steel plate 3 connects the aluminum alloy beam 15 and the lower surface of the floor slab 200. The first supporting steel plate 3 serves to enclose the space and support the fireproof sealing material. Fireproof sealing material is provided between the sealing beam 12 and the first supporting steel plate 3. The first support steel plate 3 and the second support steel plate 8 are 1.5mm thick hot-dip galvanized steel plates; the first channel steel 5 and the second channel steel 10 are galvanized.

[0033] Furthermore, such as Figure 1 As shown, a honeycomb aluminum panel backing plate 14, parallel to the glass curtain wall 100, is provided between the sealing beam 12 and the aluminum alloy beam 15. Specifically, it is an 8.5mm thick honeycomb aluminum panel backing plate 14, used to cover the fireproof sealing material, ensuring a uniform appearance and improving visual appeal. Specifically, the upper and lower ends of the honeycomb aluminum panel backing plate 14 are fixed to the sealing beam 12 or the aluminum alloy beam 15 respectively by a backing plate mounting seat; a mounting plate is provided on the outdoor-facing side of the mounting seat, and the mounting plate is fixed to the sealing beam 12 or the aluminum alloy beam 15 by screws.

[0034] Furthermore, the inclined curved glass curtain wall installation structure also includes a second supporting steel plate 8 fixed to the lower part of the first channel steel 5. The fireproof sealing material includes fireproof and heat-insulating rock wool 4 filled between the cover steel plate 13 and the first supporting steel plate 3, and fireproof and heat-insulating rock wool 4 filled in the space above the first supporting steel plate 3. The fireproof sealing material is used to prevent flames from spreading upwards or to the periphery along the gaps between floors into other rooms / floors when a fire breaks out on a floor. Since the flames rise upwards, fireproof paint is also applied to the upper surface of the fireproof and heat-insulating rock wool 4 to form a fireproof paint layer 7, which enhances the fireproof effect. The fireproof and heat-insulating rock wool 4 has a single layer thickness of 200mm, is compacted, has Class A combustion performance, and can be double-layered. The inner ends of the cover steel plate 13, the first supporting steel plate 3, and the second supporting steel plate 8 are fixed to the floor slab 200 by stainless steel nails 2 with a spacing of 30mm. Fireproof adhesive is used at the same time as stainless steel nails to enhance the fireproof performance of the connection parts. Because the spacing between the columns 16 is relatively large, and the lateral span of the first supporting steel plate 3 and the second supporting steel is relatively long, it is necessary to use angle steel 9 for reinforcement and fixation to prevent the middle part of the galvanized iron sheet from sinking and deforming downward. The two ends of the angle steel 9 are welded to the columns 16, and the angle steel is galvanized angle steel.

[0035] This utility model sets two channel steels on the floor slab 200 to form a stable support for the column 16, so that the glass curtain wall installation structure has a solid installation frame; this utility model adds a side seal 18 to the outside of the sub-frame 17 to form a double barrier, which increases the sound insulation and sealing performance, and the side seal 18 is flush with the outer surface of the aluminum alloy beam 15, which further enhances the aesthetics of the exposed part of the glass curtain wall installation structure, and also provides a fireproof structure.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
