Description

Technical Field

[0001] This invention belongs to the field of building technology and relates to a curtain wall and its assembly method. Background Technology

[0002] Curtain walls are a widely used exterior wall system in modern buildings. They not only serve as enclosures but also have multiple functions such as decoration, energy saving, and environmental protection.

[0003] Curtain walls are typically composed of panels (such as glass, metal plates, stone, etc.) and supporting structures (such as aluminum alloy frames). They can withstand their own weight and wind loads, but do not bear the load of the main structure.

[0004] Existing curtain walls typically consist of a frame, interior wall panels, and exterior wall panels, with the interior and exterior panels fixed to the inner and outer sides of the curtain wall, respectively. The interior wall panels are directly connected to the frame, and the exterior wall panels are directly connected to the frame using fasteners. This assembly method requires a high level of experience from the workers, and the multiple fastener connection points make assembly and disassembly cumbersome. Summary of the Invention

[0005] The first objective of this invention is to address the aforementioned problems in the prior art by providing a curtain wall that is easy to assemble and highly stable.

[0006] A second objective of this invention is to provide an assembly method for the aforementioned curtain wall.

[0007] The first objective of this invention can be achieved through the following technical solutions:

[0008] A curtain wall includes a frame, inner wall panels, and outer wall panels. The frame is rectangular and has several horizontally and vertically arranged connecting beams fixed inside. The connecting beams divide the interior of the frame into several adjacent frames. Each frame has a corresponding inner wall panel and an outer wall panel, which are respectively connected to the inner and outer sides of the corresponding frame. The inner wall panel has a protruding connecting part 1 on its inner side, and the outer side of the frame has a protruding connecting part 2. The connecting parts 1 and 2 are connected by a snap-fit ​​method. Each frame has a protruding connecting part 3 at its inner edge. The connecting part 3 contacts the surface of the outer wall panel and is connected to the outer wall panel by fasteners. Several inner wall panels are arranged adjacently on one side of the frame and are in the same plane, and several outer wall panels are arranged adjacently on the other side of the frame and are in the same plane.

[0009] In the aforementioned curtain wall, the first connecting part includes a sheet-shaped body, the inner side of which contacts and is fixedly connected to the inner wall panel, and the outer side of which has several protruding positioning pieces. The second connecting part includes a sheet-shaped body, the inner side of which contacts and is fixedly connected to the frame surface, and the outer side of which has several protruding positioning pieces. The positioning pieces can be embedded between two adjacent positioning pieces.

[0010] In the aforementioned curtain wall, the first body and the first positioning piece are an integral structure made of elastic material, and the second body and the second positioning piece are an integral structure made of elastic material.

[0011] In the aforementioned curtain wall, several positioning pieces are evenly distributed along the horizontal direction and all positioning pieces are parallel.

[0012] In the aforementioned curtain wall, several positioning pieces are evenly distributed along the horizontal direction and all positioning pieces are parallel.

[0013] In the aforementioned curtain wall, several connecting parts are evenly distributed along the transverse direction of the frame, and each connecting part is elongated.

[0014] In the aforementioned curtain wall, the connecting part is in the shape of a sheet, and several connecting parts are evenly distributed along the vertical direction to form a connecting unit. The number of connecting units is several, and the several connecting units are evenly distributed along the horizontal direction of the frame.

[0015] In the aforementioned curtain wall, the connecting part three has an L-shaped cross-section. One side of the connecting part three is in contact with and fixed to the connecting beam surface, and the other side of the connecting part three is in contact with and fixed to the exterior wall panel surface.

[0016] In the aforementioned curtain wall, the inner wall panel has a through positioning hole and also includes a connecting piece passing through the positioning hole. The outer end of the connecting piece extends out of the outer side of the inner wall panel and has an outer connecting end for fixing to the wall. The inner end of the connecting piece has a protruding inner connecting end and is fixedly connected to the frame.

[0017] The second objective of this invention can be achieved through the following technical solutions:

[0018] An assembly method for a curtain wall, the curtain wall comprising a frame, inner wall panels, outer wall panels, and connecting beams, the assembly method comprising the following steps:

[0019] A. Preparation: Prepare the frame, inner wall panels, outer wall panels and connecting beams. At the same time, fix the connecting part to the inner wall panel.

[0020] B. Frame assembly: There are several connecting beams. Some of the connecting beams are connected to the frame in the transverse direction, and the other part of the connecting beams are connected to the frame in the longitudinal direction. Several connecting beams form several adjacent frames in the frame.

[0021] Next, the two connecting parts are connected to the two sides of the frame, namely connecting part two and connecting part three.

[0022] C. External wall panel connection: Fasteners are used to connect the external wall panels to the connecting parts, and finally the external wall panels are connected to the outside of the frame;

[0023] D. Connection of inner wall panels: After fasteners are used to connect the second connection part to the first connection part, the inner side of the frame is stably connected to the inner wall panel.

[0024] In the above-mentioned curtain wall assembly method, after step C, the sealing strip is installed between two adjacent exterior wall panels from the inside of the frame.

[0025] Compared with existing technologies, this curtain wall has a compact structure and is easy to assemble because the frame is divided into several independent and adjacent frames, and each frame is connected to corresponding inner and outer wall panels on the inside and outside.

[0026] Meanwhile, connector three not only contacts the exterior wall panel but also securely connects it, ensuring the stability of the connection between the exterior wall panel and the frame. Connectors one and two are connected by a snap-fit ​​method, which is not only convenient and quick to connect but also relatively stable. Therefore, the entire curtain wall assembly is simple and highly stable.

[0027] In addition, the three connecting parts enable the outer wall panel to be connected to the frame in a convenient, quick and stable manner, while the one connecting parts and the two connecting parts enable the inner wall panel to be connected to the frame in a convenient, quick and stable manner. Therefore, the entire assembly method is convenient and fast, with high assembly efficiency and high practical value. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] It should be noted that when a component is said to be "mounted on" another component, it can be directly mounted on the other component or may be interspersed with a component. When a component is said to be "set on" another component, it can be directly set on the other component or may be interspersed with a component. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or may be interspersed with a component.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] like Figure 1 and Figure 2 and Figure 3 and Figure 4 As shown, this curtain wall includes a frame 1, an inner wall panel 2, and an outer wall panel 3. The frame 1 is square and has several horizontally and vertically arranged connecting beams 4 fixed inside the frame 1. The connecting beams 4 divide the interior of the frame 1 into several adjacent frames. Each frame has a corresponding inner wall panel 2 and an outer wall panel 3. The inner wall panel 2 and the outer wall panel 3 are respectively connected to the inner and outer sides of the corresponding frame.

[0042] The inner wall panel 2 has a protruding connecting part 5 on its inner side, and the frame 1 has a protruding connecting part 6 on its outer side. The connecting part 5 and the connecting part 6 are connected by a snap-fit ​​method. Each frame has a protruding connecting part 7 on its inner edge. The connecting part 7 is in contact with the outer wall panel 3 and is connected to the outer wall panel 3 by fasteners. Several inner wall panels 2 are arranged adjacent to each other on one side of the frame 1 and are on the same plane. Several outer wall panels 3 are arranged adjacent to each other on the other side of the frame 1 and are on the same plane.

[0043] Since connecting part 2 6 and connecting part 3 7 are connected to the inner and outer sides of the frame 1 respectively, connecting part 1 5 on the inner wall panel 2 can be stably connected to the frame 1 after it is connected with connecting part 2 6, and connecting part 3 7 can be stably connected to the frame 1 after it is connected with the outer wall panel 3.

[0044] It can be seen that the above structure ultimately and stably connects the inner wall panel 2 and the outer wall panel 3 to both sides of the frame 1.

[0045] Meanwhile, the connecting beam 4 divides the interior of the relatively large frame 1 into several independent and adjacent frames. Each frame is connected to the corresponding outer wall panel 3 and inner wall panel 2 on its inner and outer layers, which ultimately enables several inner wall panels 2 and outer wall panels 3 to be stably and flush connected to the inner and outer sides of the frame 1.

[0046] Of course, after the connection, several inner wall panels 2 will abut together, and there will be no obvious large gap between two adjacent inner wall panels 2. At the same time, there will also be no obvious large gap between two adjacent outer wall panels 3.

[0047] The connecting part 5 includes a sheet-shaped body 5a, the inner side of which contacts and is fixedly connected to the inner wall panel 2. The outer side of the body 5a has several protruding positioning pieces 5b. The connecting part 6 includes a sheet-shaped body 6a, the inner side of which contacts and is fixedly connected to the frame 1. The outer side of the body 6a has several protruding positioning pieces 6b. The positioning pieces 5b can be embedded between two adjacent positioning pieces 6b.

[0048] The sheet-like body 5a contacts and connects with the inner wall panel 2, which effectively improves the connection stability between the connecting part 5 and the inner wall panel 2.

[0049] Meanwhile, several positioning plates 5b are evenly distributed on the outside of the main body 5a, and the entire connecting part 5 forms a structure similar to heat dissipation fins.

[0050] Similarly, the second body 6a is in contact with and connected to the frame 1, which can effectively improve the connection stability between the second connecting part 6 and the frame 1.

[0051] Meanwhile, several positioning plates 26b are evenly distributed on the outer side of the main body 26a, and the entire connecting part 26 forms a structure similar to heat dissipation fins.

[0052] The first body 5a and the first positioning piece 5b are an integral structure and are made of elastic material, and the second body 6a and the second positioning piece 6b are an integral structure and are made of elastic material.

[0053] Both connecting part 5 and connecting part 6 are made of plastic or elastic metal.

[0054] Several positioning pieces 5b are evenly distributed in the transverse direction and all positioning pieces 5b are parallel.

[0055] Several positioning pieces 2 6b are evenly distributed in the transverse direction and all positioning pieces 2 6b are parallel.

[0056] The width of the positioning piece 5b matches the gap between the two adjacent positioning pieces 6b. This structure ensures that the connecting part 5 and the connecting part 6 can be stably connected together.

[0057] Of course, the width of positioning piece 2 6b is also matched with the gap between the two adjacent positioning pieces 1 5b.

[0058] Several connecting parts 5 are evenly distributed along the transverse direction of the skeleton 1, and the connecting parts 5 are elongated.

[0059] This simplifies the structure of the connecting part 5, and because the connecting part 5 is relatively long, it can also appropriately improve the connection stability.

[0060] Depending on the actual situation, another solution can be adopted, namely: the connecting part 5 is in the shape of a sheet, and several connecting parts 5 are evenly distributed in the vertical direction to form a connecting unit. The number of connecting units is several, and the several connecting units are evenly distributed in the horizontal direction of the skeleton 1.

[0061] Although the multiple vertical connecting parts (5) make the structure more complex, they save materials and appropriately reduce the cost of the curtain wall.

[0062] Several solutions can be adopted when connecting part 5 and connecting part 6 are matched:

[0063] Firstly, the long strip-shaped connecting part 5 is connected to several sheet-shaped connecting parts 6.

[0064] Secondly, the long strip-shaped connecting part 26 is connected to several sheet-shaped connecting parts 15;

[0065] Thirdly, the long strip-shaped connecting part 5 and the long strip-shaped connecting part 6 are connected together.

[0066] It can be seen that regardless of which scheme is adopted, the connecting part 5 and the connecting part 6 can be stably fastened together.

[0067] The connecting part 3 7 has an L-shaped cross section. One side of the connecting part 3 7 is in contact with and fixed to the connecting beam 4, and the other side of the connecting part 3 7 is in contact with and fixed to the outer wall panel 3.

[0068] The two sides of the connecting part 3 7 are in contact with the connecting beam 4 and the outer wall panel 3 respectively, which effectively improves the connection stability between the outer wall panel 3 and the connecting beam 4.

[0069] In this embodiment, to further improve the connection stability between the exterior wall panel 3 and the frame, a reinforcing beam 9 is also provided inside the frame, and a connecting part 7 is also provided at the reinforcing beam 9. It can be seen that this effectively increases the connection points between the exterior wall panel 3 and the frame, ultimately improving stability.

[0070] The inner wall panel 2 has a through positioning hole 2a and also includes a connecting piece 8 that passes through the positioning hole 2a. The outer end of the connecting piece 8 extends out of the outer side of the inner wall panel 2 and has an outer connecting end 8b for fixing to the wall. The inner end of the connecting piece 8 has a protruding inner connecting end 8a and the inner connecting end 8a is fixedly connected to the frame 1.

[0071] External connection end 8b is used to connect to the wall, and external connection end 8b is used to connect to the frame 1. This structure can ultimately fix the frame 1 stably to the wall, and correspondingly, stably connect the curtain wall to the wall.

[0072] The curtain wall includes a frame 1, inner wall panels 2, outer wall panels 3, and connecting beams 4. The assembly method of this curtain wall includes the following steps:

[0073] A. Preparation: Prepare the frame 1, inner wall panel 2, outer wall panel 3 and connecting beam 4. At the same time, fix the connecting part 5 to the inner wall panel 2.

[0074] B. Frame assembly: There are several connecting beams 4. Some of the connecting beams 4 are connected to the frame 1 in the transverse direction, and the other part of the connecting beams 4 are connected to the frame 1 in the longitudinal direction. Several connecting beams 4 form several adjacent frames in the frame 1.

[0075] Next, the connecting part 2 6 and the connecting part 3 7 are connected to the two sides of the frame 1 respectively;

[0076] C. External wall panel connection: Fasteners are used to connect the external wall panel 3 to the connecting part 7, and finally the external wall panel 3 is connected to the outside of the frame 1;

[0077] After step C, the sealing strip is inserted between two adjacent exterior wall panels 3 from the inside of the frame 1.

[0078] Interior wall panel connection: After fasteners are used to connect the second part 6 and the first part 5, the inner side of the frame 1 is stably connected to the interior wall panel 2.

[0079] In step A, a through positioning hole 2a is pre-drilled on the inner wall panel 2. Between steps C and D, the connecting piece 8 is inserted through the positioning hole 2a. The inner end of the connecting piece 8 is the inner connecting end 8a, and the outer end of the connecting piece 8 is the outer connecting end 8b. The inner connecting end 8a is located inside the inner wall panel 2 and is connected to the frame 1 by fasteners. The outer connecting end 8b is connected to the wall, which ultimately enables the entire curtain wall to be stably connected to the wall.

[0080] Meanwhile, between steps C and D, wiring harness installation can also be performed. The wiring harness includes electrical wires, network cables, and air conditioning pipes, etc.

[0081] In this embodiment, the inner connecting end 8a is L-shaped, one side of the inner connecting end 8a is fixedly connected to the connecting piece 8, and the other side of the inner connecting end 8a is in contact with and fixedly connected to the skeleton surface.

[0082] like Figure 5 As shown, the external connection end 8b is cross-shaped, and a positioning plate 10 is horizontally connected to the wall panel. The inner end of the positioning plate 10 is fixed to the wall, and the outer end of the positioning plate 10 has a positioning port 10a that matches the external connection end 8b.

[0083] like Figure 6 As shown, the sealing strip 30 includes a sealing part 3b and a limiting part 3a. The thickness of the limiting part 3a is greater than the thickness of the sealing part 3b. The sealing part 3b is embedded between two adjacent outer wall panels 3, and the limiting part 3a abuts against the inner side of the outer wall panel 3. To further improve the sealing performance, an adhesive tape 3c is also provided at the limiting part 3a.

[0084] The sealing strip 30 is made of flexible material; in this embodiment, the sealing strip 30 is made of rubber.

[0085] Of course, the outer end of the sealing part 3b is flush with the outer side of the outer wall panel 3, which can appropriately improve the structural compactness of the entire curtain wall.

[0086] like Figure 7 and Figure 8 As shown, it also includes a panel gap positioning component. A cross-shaped connection gap is formed at the connection between four adjacent exterior wall panels 3. The panel gap positioning component is located at the connection gap. The panel gap positioning component can position and connect the four adjacent exterior wall panels 3.

[0087] The panel gap positioning component includes a frame-shaped positioning frame 13 and a positioning groove 14 recessed on the inner side of the outer wall panel 3. The positioning grooves 14 of four adjacent outer wall panels 3 are connected in sequence to form a locking part that matches the positioning frame 13. The positioning frame 13 is embedded in the locking part.

[0088] In this embodiment, the positioning frame 13 is square, and the positioning groove 14 on each outer wall panel is L-shaped. The two ports of the positioning groove 14 are located at the adjacent edges of the cross-shaped connecting gap.

[0089] Similarly, the four adjacent interior wall panels 2 can also be positioned and connected using panel gap positioning components.

[0090] The inner wall panel 2 has a protruding connecting part 5 on its inner side, and the frame 1 has a protruding connecting part 6 on its outer side. The connecting part 5 and the connecting part 6 are connected by a snap-fit ​​method. Each frame has a protruding connecting part 7 on its inner edge. The connecting part 7 is in contact with the outer wall panel 3 and is connected to the outer wall panel 3 by fasteners. Several inner wall panels 2 are arranged adjacent to each other on one side of the frame 1 and are on the same plane. Several outer wall panels 3 are arranged adjacent to each other on the other side of the frame 1 and are on the same plane.

[0091] like Figure 9 As shown, due to the relatively low strength at the gap between two adjacent inner wall panels 2, the aforementioned location of the inner wall panel 2 is prone to damage or deformation under external force.

[0092] Therefore, the connecting part 2 6 has a protruding support part 15 in the middle, and the edges of the two adjacent inner wall panels 2 are located at the support part 15. Since the support part 15 supports the edges of the inner wall panels 2, the inner wall panels 2 are not easily damaged or deformed even when subjected to relatively large external forces.

[0093] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
