[0002] As an important part of the outer facade of modern high-rise buildings, curtain walls not only play the role of beautifying the building appearance, but also have functions such as heat insulation, sound insulation, and waterproofing. However, with the temperature changes brought about by seasonal variations, building materials will undergo displacement due to the physical properties of thermal expansion and contraction, which makes it necessary to consider the expansion and contraction problems of curtain walls during the design and construction processes. Currently, the design and construction of curtain wall expansion joints have become one of the important links to ensure the long-term stability and safety of the curtain wall system.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0024] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "center", "top", "bottom", "top part", "bottom part", "inner", "outer", "inner side", "outer side", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. Among them, the "inner side" refers to the internal or enclosed area or space. The "periphery" refers to the area surrounding a specific component or a specific area.

[0025] Refer to Figures 1-6, An innovative curtain wall with an expansion joint D, comprising a connection assembly 200, a first vertical column 300, a second vertical column 400, a first telescopic member 500, a second telescopic member 600, a third telescopic member 700, and a panel 800; the connection assembly 200 is connected to the wall 100, the first vertical column 300 and the second vertical column 400 are fixed to the connection assembly 200, the first telescopic member 500 is fixed to the first vertical column 300, the second telescopic member 600 is fixed to the second vertical column 400, one side of the third telescopic member 700 is fixedly connected to the panel 800, the other side of the third telescopic member 700 is inserted into the first telescopic member 500, and an expansion joint D for left - right expansion is provided between the right side of the first telescopic member 500 and the left side of the second vertical column 400.

[0026] In the existing curtain wall, the expansion joint D is arranged on the outer facade of the curtain wall, which destroys the aesthetics, heat insulation and waterproof performance of the curtain wall. The conventional solution is to fill the expansion joint D with rubber or sealant 403. However, the rubber and sealant 403 are prone to aging and falling off, requiring replacement, resulting in high maintenance costs. Based on the above problems, through the setting of the expansion joint D, the functional requirements for the expansion of building materials are met. Through the setting of the connection assembly 200, the first vertical column 300, the second vertical column 400, the first telescopic member 500, the second telescopic member 600, the third telescopic member 700, and the panel 800, the expansion joint D is hidden behind the panel 800, ensuring the unity of the curtain wall facade, enhancing the curtain wall effect and quality, and solving the problems of heat insulation and water leakage of the expansion joint D in the existing curtain wall; by setting the connection assembly 200, the first vertical column 300, and the second vertical column 400, the curtain wall structure is made more stable. Solve the problems of difficult waterproofing when the expansion joint D of the curtain wall is arranged on the outer facade, and the destruction of the aesthetics, heat insulation and waterproof performance of the curtain wall.

[0027] During the installation process of the innovative curtain wall, a wall 100 with an uneven outer surface will be encountered, making the installation of the innovative curtain wall difficult. Based on the above problems, it is necessary to adjust the components that play a supporting role, and then install the remaining components on the supporting components. The first steel plate 201, the second steel plate 202, the first vertical column 300, the second vertical column 400, the first cross - beam 203, and the second cross - beam 204 all play a supporting role. Therefore, only the positions of the first steel plate 201, the second steel plate 202, the first vertical column 300, the second vertical column 400, the first cross - beam 203, and the second cross - beam 204 relative to the wall 100 need to be adjusted, and then the shapes of the first cross - beam 203, the second cross - beam 204, and the panel 800 are changed to match the shape of the outer surface of the wall 100, so that the innovative curtain wall can be successfully installed; this innovative curtain wall can adapt to various shapes of walls 100, such as the inside corner, outside corner, and undulating outer surface of the wall 100, such as Figure 6As shown, it is a cross-sectional view of the innovative curtain wall with expansion joint D installed at the internal corner of wall 100. Optionally, both the first steel plate 201 and the second steel plate 202 are 1.5-mm thick hot-dip galvanized steel plates, and the first upright column 300 and the second upright column 400 are made of aluminum alloy materials. The first steel plate 201, the second steel plate 202, the first upright column 300, and the second upright column 400 all have excellent corrosion resistance, delaying rusting, and thus extending the service life of the curtain wall.

[0028] The panel 800 can be selected from a metal panel 800, a stone panel 800, or a composite material panel 800 according to the building requirements; the panel 800 of this innovative curtain wall is selected as double-layer glass, and an aluminum strip, molecular sieve, and sealant 403 are provided between the double-layer glass. The thickness of the aluminum strip is 12 mm, ensuring a constant distance between the double-layer glass, thus forming a spacer layer; the molecular sieve functions to adsorb the moisture in the glass spacer layer and keep the spacer layer dry; the sealant 403 functions to fixedly connect the aluminum strip, molecular sieve, and double-layer glass.

[0029] In some embodiments, the first telescopic member 500 is provided with a first groove 501, one side of the third telescopic member 700 is inserted into the first groove 501, the depth of the first groove 501 is 10 mm to 40 mm, and the width of the expansion joint D is equal to the depth of the first groove 501.

[0030] As Figures 3-4 shown, the settings of the first groove 501 and the expansion joint DD meet the requirements of the curtain wall materials for thermal expansion and contraction due to temperature changes, and also limit the left-right telescopic range of the first telescopic member 500, the second telescopic member 600, and the third telescopic member 700. Preferably, the depth of the first groove 501 and the width of the expansion joint DD are both 30 mm, which not only avoids the expansion joint DD being set too wide and affecting the stability of the overall structure of the curtain wall, but also avoids the expansion joint DD being set too narrow and unable to meet the requirements of the curtain wall materials for thermal expansion and contraction due to temperature changes.

[0031] In some embodiments, a first silica gel strip 602 is provided between the second telescopic member 600 and the first telescopic member 500. A second groove 601 is provided on one side of the second telescopic member 600. A first protrusion 6021 is provided on the top of the first silica gel strip 602, and the first protrusion 6021 is clamped in the second groove 601. The first silica gel strip 602 is provided with a first cavity 6022, and the bottom of the first silica gel strip 602 abuts against the first telescopic member 500.

[0032] The first cavity 6022 increases the elasticity of the first silicone strip 602, enabling the first silicone strip 602 to better adapt to different installation conditions and environmental changes. When the first telescopic member 500 and the second telescopic member 600 are mutually extruded, the first cavity 6022 deforms under force, reducing the acting force between the first telescopic member 500 and the second telescopic member 600, thus playing a buffering role. Compared with the method of pasting the first silicone strip 602 with glue, by using the method of clamping the first protrusion 6021 in the second groove 601, on the one hand, the first silicone strip 602 is more stably connected to the second telescopic member 600, avoiding the detachment of the first silicone strip 602 due to glue aging. On the other hand, it makes the replacement of the first silicone strip 602 more convenient.

[0033] In some embodiments, the connection assembly 200 includes a first steel plate 201, a second steel plate 202, a first cross beam 203 and a second cross beam 204. The first steel plate 201 and the second steel plate 202 are symmetrically fixed to the wall 100. The first upright column 300 is fixed to the first steel plate 201, and the second upright column 400 is fixed to the second steel plate 202. The first cross beam 203 is vertically fixed to the first upright column 300, and the second cross beam 204 is vertically fixed to the second upright column 400. The first upright column 300, the second upright column 400, the first cross beam 203 and the second cross beam 204 are all used for installing the panel 800.

[0034] Fixed to the wall 100 through the first steel plate 201 and the second steel plate 202, and forming a frame structure through the first upright column 300, the second upright column 400, the first cross beam 203 and the second cross beam 204 can improve the structural stability of the entire system and also facilitate the installation of the panel 800.

[0035] Preferably, the connection assembly 200 further includes a first sleeve core 205 and a second sleeve core 206. The first sleeve core 205 is vertically fixed to the first upright column 300, and the second sleeve core 206 is vertically fixed to the second upright column 400. The first cross beam 203 is sleeved outside the first sleeve core 205, and the second cross beam 204 is sleeved outside the second sleeve core 206.

[0036] The connection methods of the first cross beam 203 and the first core set 205, as well as the second cross beam 204 and the second core set 206, are both plug-in types. Taking the first cross beam 203 and the first core set 205 as an example, during installation, only need to insert the first cross beam 203 into the first core set 205. The operation is simple and fast. When disassembly or adjustment is required, the first cross beam 203 can be easily removed, which is convenient for maintaining or reconfiguring the first cross beam 203. The first core set 205 provides a stable support point, ensuring a firm connection between the first cross beam 203 and the first vertical column 300, and reducing potential safety hazards caused by unstable structures. By pre-installing the first core set 205, the position of the first cross beam 203 can be adjusted according to actual needs, enabling flexible layout. Using the first core set 205 reduces the need for docking, replaces welding or other permanent fixing methods, reduces construction costs, decreases the workload of on-site processing, and improves construction efficiency.

[0037] Preferably, the cross-sections of the first steel plate 201 and the second steel plate 202 are both L-shaped. The short sides of the first steel plate 201 and the second steel plate 202 are both fixed to the wall body 100. Fireproof rock wool 207 is provided on the outer sides of the long sides of the first steel plate 201 and the second steel plate 202. The inner side of the long side of the first steel plate 201 is fixedly connected to the first vertical column 300, and the inner side of the long side of the second steel plate 202 is fixedly connected to the second vertical column 400.

[0038] The L-shaped first steel plate 201 and second steel plate 202 provide good supporting force. The short sides of the first steel plate 201 and the second steel plate 202 are fixed to the wall body 100 to ensure the stability of the entire curtain wall structure. The inner side of the long side of the first steel plate 201 is fixedly connected to the first vertical column 300, and the inner side of the long side of the second steel plate 202 is fixedly connected to the second vertical column 400, enabling a large adjustment range for the first vertical column 300 and the second vertical column 400, so that the curtain wall can better adapt to walls of different shapes, increasing the flexibility and application range of curtain wall installation. The fireproof rock wool 207 plays a role in fire isolation, heat insulation, and noise reduction. Specifically, the thickness of the fireproof rock wool 207 is 150 mm to 250 mm. The above design ensures that the expansion joint DD is hidden behind the panel 800, takes into account the safety and stability of the curtain wall, and also takes into account multiple functions such as fire prevention, heat insulation, and sound insulation, improving the overall performance and usage experience of the building.

[0039] Preferably, the second vertical column 400 is fixedly connected with a first pressing member 401. The first pressing member 401 covers the vertical side of the panel 800 for fixing the panel 800, and a first buckle cover 402 is snap-connected to the first pressing member 401. Second pressing members 208 are fixedly connected to both the first cross beam 203 and the second cross beam 204. The second pressing members 208 cover the horizontal sides of the panel 800 for fixing the panel 800, and a second buckle cover 209 is snap-connected to the second pressing member 208.

[0040] To firmly install the panel 800, a first pressing member 401 and a second pressing member 208 are provided to fix the panel 800 from the side edges of the panel 800. The first pressing member 401 and the second column 400 are fixedly connected by bolts to fix from the vertical side edges of the panel 800; the second pressing member 208 and the first cross beam 203 are fixedly connected by bolts, and the second pressing member 208 and the second cross beam 204 are fixedly connected by bolts to fix from the horizontal side edges of the panel 800; to protect the edges of the panel 800 from damage and prevent the edges of the panel 800 from being damaged due to collision or uneven force. After fixing, the bolt heads are exposed outside the first pressing member 401 and the second pressing member 208. On the one hand, it affects the aesthetics of the curtain wall, and on the other hand, the bolt heads are prone to rust due to rain. Therefore, a first cover 402 and a second cover 209 need to be provided. The first cover 402 is snap-fitted on the first pressing member 401, and the second cover 209 is snap-fitted on the second pressing member 208, both of which play a role in covering the bolts, making the curtain wall more beautiful and preventing rain from wetting the bolts; the connection by snap-fitting simplifies the installation steps and also facilitates the later maintenance and replacement of the panel 800.

[0041] Further preferably, the connection assembly 200 further includes a second silicone strip 210. The top of the second silicone strip 210 is provided with a second protrusion 2101, the middle of the second silicone strip 210 is provided with a second cavity 2102, the bottom surface of the second silicone strip 210 is provided with a plurality of friction strips 2103, and a plurality of second silicone strips 210 are provided, which are respectively snap-fitted on the second column 400, the first cross beam 203, the second cross beam 204, the first pressing member 401 and the second pressing member 208 through the second protrusion 2101, and the friction strips 2103 are in contact with the panel 800.

[0042] The second cavity 2102 increases the elasticity of the second silicone strip 210, enabling the second silicone strip 210 to better adapt to different installation conditions and environmental changes. The second cavity 2102 deforms under force, reducing the acting force of the second column 400, the first cross beam 203, the second cross beam 204, the first pressing member 401 and the second pressing member 208 on the panel 800, and the second silicone strip 210 plays a buffering role; compared with the method of pasting the second silicone strip 210 with glue, the method of snap-fitting with the second protrusion 2101, on the one hand, more stably fixes the second silicone strip 210, avoiding the second silicone strip 210 falling off due to glue aging, and on the other hand, making the replacement of the second silicone strip 210 more convenient. The friction strips 2103 play a role in increasing friction and better fixing the panel 800.

[0043] Preferably, a sealant 403 and a foam rod 404 are provided between the panel 800 and the second column 400, and rubber gaskets are provided on both the first cross beam 203 and the second cross beam 204.

[0044] The sealant 403 functions to prevent water and dust ingress and fix the foam rod 404. Both the foam rod 404 and the rubber gasket serve as buffers. When the curtain wall is subjected to external force impacts or when the second column 400, the panel 800, the first cross beam 203, and the second cross beam 204 expand and contract due to temperature changes, the foam rod 404 and the rubber gasket absorb the impact force, thereby reducing direct damage to the panel 800.

[0045] In some embodiments, an innovative curtain wall with expansion joints further includes a thermal insulation and waterproofing assembly 900. The thermal insulation and waterproofing assembly 900 includes a thermal insulation cotton 901, a third steel plate 902, a fourth steel plate 903, a fixing member 904, and a sealing strip 905. First extension plates 9021 are provided on both sides of the third steel plate 902, and second extension plates 9031 are provided on both sides of the fourth steel plate 903. The thermal insulation cotton 901, the first extension plates 9021, and the second extension plates 9031 are all fixed to the wall 100. The third steel plate 902 is located at the rear side of the thermal insulation cotton 901, and the fourth steel plate 903 is located at the front side of the thermal insulation cotton 901. The cross-sections of the thermal insulation cotton 901, the third steel plate 902, and the fourth steel plate 903 are all in the shape of an inverted V. The fixing member 904 is fixed to the second extension plate 9031. The fixing member 904 is provided with a third groove 9041. First protrusions 9051 are provided on both sides of the sealing strip 905. The sides of the third groove 9041 and the first protrusions 9051 are both serrated. The first protrusions 9051 are snap-fitted into the third groove 9041. The cross-section of the sealing strip 905 is in a continuous W shape, similar to a bellows strip.

[0046] The thermal insulation cotton 901 functions to provide thermal insulation. The inverted V-shaped structures of the thermal insulation cotton 901, the third steel plate 902, and the fourth steel plate 903 enable the third steel plate 902 and the fourth steel plate 903 to deform along their own inverted V-shaped structures when subjected to wall extrusion or their own thermal expansion and contraction, thereby avoiding self-destruction. The provision of the first extension plates 9021 facilitates the connection between the third steel plate 902 and the wall 100, and the provision of the second extension plates 9031 facilitates the connection between the fourth steel plate 903 and the wall 100. Both the third steel plate 902 and the fourth steel plate 903 function to fix the thermal insulation cotton 901 and increase the structural stability of the wall 100. To waterproof and moisture-proof the fourth steel plate 903, a sealing strip 905 is provided on one side of the fourth steel plate 903. The sealing strip 905 functions to prevent water and moisture ingress, dust and insect intrusion. Specifically, the sealing strip 905 is made of rubber material. The sealing strip 905 with a cross-section in a continuous W shape adapts to gaps of different sizes in the wall 100 or uneven wall surfaces through its own elasticity, ensuring good sealing effects under various conditions. As Figure 5 shown, to make the connection between the sealing strip 905 and the fixing member 904 more convenient and tight, the sides of the third groove 9041 and the first protrusions 9051 are both provided as serrated.

[0047] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
