Description

Technical Field

[0001] This utility model relates to an energy-saving internal corner structure for a zigzag curtain wall, belonging to the field of building curtain walls. Background Technology

[0002] In modern building curtain wall design, zigzag curtain walls are widely used due to their flexible shapes. The connection structure at the inside corners directly affects the sealing performance and energy-saving effect of the curtain wall. Currently, the inside corners of zigzag curtain walls mostly adopt a male and female column splicing structure. The glass panels are connected to the columns with sealant, while operable windows need to be separately framed before being assembled with the female column.

[0003] Traditional operable window subframes and columns are designed separately, which can easily create gaps at the joints. A single sealing strip is insufficient to prevent air infiltration, leading to increased building energy consumption. Furthermore, the connection between male and female columns is often a rigid contact without a dedicated plug-in buffer structure. The sealing strip is prone to failure due to installation errors or thermal expansion and contraction, causing rainwater leakage. At the same time, the direct connection of metal columns creates thermal bridges, exacerbating heat exchange between indoors and outdoors, which does not meet the current building energy efficiency standards for curtain wall heat transfer coefficients.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] As attached Figure 1-2As shown, the present invention discloses an energy-saving internal corner structure for a zigzag curtain wall, comprising a male column 1, a female column 2, a glass panel 3, and an operable window 4. In this embodiment, both the male column 1 and the female column 2 are made of aluminum alloy profiles. Aluminum alloy has the characteristics of high strength, corrosion resistance, and lightweight, which can meet the load-bearing requirements of the curtain wall structure and adapt to the long-term use environment of the building facade.

[0020] At least one set of corresponding fitting grooves 11 are provided on the opposite sides of the male column 1 and the female column 2. A flexible plug 5 is provided between the male column 1 and the female column 2. The two ends of the flexible plug 5 are respectively embedded in the fitting grooves 11 of the male column 1 and the female column 2 to connect the male column 1 and the female column 2, so that the male column 1 and the female column 2 become a whole. The use of flexible plug 5 to replace the traditional rigid contact connection can effectively buffer the deformation of the male and female columns 2 caused by installation errors or temperature changes, and avoid damage to the connection structure caused by rigid compression.

[0021] In this embodiment, the flexible plug-in 5 can be made of materials such as rubber or modified polyvinyl chloride. The mating grooves 11 on the male column 1 and the female column 2 are each provided with two sets, which can be increased or decreased according to the actual situation during use.

[0022] Furthermore, EPDM rubber strips 51 are provided at both ends of the flexible plug 5 and at the contact positions with the fitting groove 11. Through the excellent weather resistance, elasticity and sealing performance of the EPDM rubber strips 51, the sealing performance of the connection between the male column 1 and the female column 2 can be further enhanced, blocking the path of air infiltration and rainwater leakage, and solving the problem of easy failure of the sealing strip 7 in traditional rigid connections.

[0023] The glass panel 3 is installed and fixed at the front end of the public column 1. In this embodiment, the glass panel 3 is bonded and fixed to the front end of the public column 1 with structural adhesive 9 to ensure a stable connection between the glass panel 3 and the public column 1, while ensuring a sealing effect.

[0024] Furthermore, an aluminum alloy edge protector 12 is provided at the front end of the public column 1, and an aluminum alloy pressure plate 31 is provided at the end of the glass panel 3. A thermal insulation strip 6 is provided between the aluminum alloy edge protector 12 at the front end of the public column 1 and the aluminum alloy pressure plate 31 at the end of the glass panel 3. The thermal insulation strip 6 connects the aluminum alloy edge protector 12 and the aluminum alloy pressure plate 31. The aluminum alloy pressure plate 31 can effectively protect the end of the glass panel 3, preventing the glass from being damaged by external impact. The thermal insulation strip 6 can block the direct heat conduction between the public column 1 and the aluminum alloy pressure plate 31 at the end of the glass panel 3, reduce the thermal bridge formed by the metal components, reduce the efficiency of indoor and outdoor heat exchange, and improve the energy-saving performance of the curtain wall.

[0025] In addition, a sealing strip 7 is provided between the aluminum alloy pressure plate 31 on one side of the public column 1 and the outer wall of the glass panel 3 to further fill the tiny gaps between the aluminum alloy pressure plate 31 and the glass panel 3, enhance the sealing performance of the installation part of the glass panel 3, and prevent rainwater, dust or airflow from seeping into the room through the gaps.

[0026] When the aluminum alloy edge protector 12 is connected to the aluminum alloy edge protector 12, a heat insulation cavity 8 is formed between the aluminum alloy pressure plate 31 and the public column 1. By utilizing the low thermal conductivity of air, the heat transfer between the public column 1 and the pressure plate is reduced. Together with the heat insulation strip 6, a double heat insulation barrier is formed, which further improves the thermal insulation effect of the curtain wall.

[0027] The front end of the mother column 2 is integrally machined with a mounting base 21, and the opening window 4 is installed and fixed on the mounting base 21. Unlike existing technologies, there is no need to add a separate sub-frame, thus saving processes and materials.

[0028] Specifically, the operable window 4 includes an aluminum alloy window frame 41 and an aluminum alloy window sash 42. The aluminum alloy window sash 42 is installed on the aluminum alloy window frame 41 and is sealed to the aluminum alloy window frame 41 with sealant. The aluminum alloy window frame 41 is installed and fixed on the mounting base 21 by bolts and other connecting parts.

[0029] The mother column 2 and the mounting base 21 are integrally formed, which avoids the splicing gap problem caused by the separate design of the traditional operable window 4 frame and column, and reduces the path of air infiltration from the structure. At the same time, the direct connection between the operable window 4 and the mounting base 21 simplifies the installation process and reduces the risk of sealing failure due to assembly errors.

[0030] Furthermore, similar to the installation location of the glass panel 3, an aluminum alloy pressure plate 31 is also provided at the front end of the main column 2, and an aluminum alloy pressure plate 31 is provided at the end of the mounting base 21. A heat insulation strip 6 is provided between the aluminum alloy guard 12 at the front end of the main column 2 and the aluminum alloy pressure plate 31 at the end of the mounting base 21 to connect the aluminum alloy pressure plate 31 and the aluminum alloy pressure plate 31. A sealing strip 7 is provided between the aluminum alloy pressure plate 31 on one side of the main column 2 and the outer wall of the mounting base 21. After the opening window 4 is installed, a heat insulation cavity 8 is formed between the aluminum alloy pressure plate 31 and the main column 2 to ensure the heat insulation effect.

[0031] The thermal insulation strip 6 and the thermal insulation cavity 8 block the heat conduction between the main column 2 and the mounting base 21, and the sealing strip 7 enhances the sealing of the installation part of the openable window 4, together improving the energy-saving and sealing performance of the area of ​​the openable window 4.

[0032] In summary, this application reduces the gap between the operable window 4 and the column by integrally molding the female column 2 and the mounting base 21, and blocks air infiltration with the sealing strip 7; it achieves flexible connection between the male and female columns 2 with the flexible plug 5, and buffers deformation with the EPDM rubber strip 51 to avoid sealing failure and rainwater leakage; it uses the thermal insulation strip 6 and thermal insulation cavity 8 to block metal thermal bridges, reduce heat exchange, effectively improve the sealing performance and energy-saving effect of the curtain wall, and meet the building energy conservation standards.

[0033] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
