[0033] To meet the living needs of modern people, curtain wall panels, especially metal curtain wall panels, have gradually become widely used building materials in high-end buildings due to their perfect appearance, excellent quality, light self-weight and other advantages. Traditional curtain wall panels include a metal frame, and the metal frame includes a plurality of U-shaped metal pipe grooves. The groove openings of the U-shaped metal pipe grooves face indoors, and the side opposite to the groove opening faces outdoors. Subsequently, fillers such as wooden strips will be filled in the U-shaped metal pipe grooves to achieve a supporting effect, and a concrete layer will be formed on the outdoor side, that is, the side opposite to the groove opening.

[0034] In the actual use process of the above-mentioned curtain wall panel, the supporting strength of the fillers in the U-shaped metal pipe grooves is insufficient, and the connection strength between the concrete layer formed on the outdoor side and the metal frame is not strong enough, resulting in insufficient overall strength of the formed curtain wall panel and poor force stability.

[0035] To solve the above problems, the embodiments of the present invention provide a curtain wall panel, a composite curtain wall panel and a method for forming the same. The curtain wall panel includes a plurality of frame units, the frame units have a hollow structure, the frame units include opposite first side portions and second side portions, and there is an opening in the second side portion. The plurality of frame units are arranged and connected in the first direction and the second direction respectively to form a frame assembly. The concrete layer is located on the second side portion with an opening of each frame unit, and fills the hollow structure of each frame unit through the opening. The concrete forms an interlock with the frame unit, thereby forming a steel-concrete structure, and the connection between the concrete layer and the frame unit is better, so that the strength of the formed curtain wall panel is greatly improved, and the stability of the force structure is better.

[0036] To make the above objects, features and beneficial effects of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0039] It should be noted that Figure 1 and Figure 2 are schematic diagrams of the structure with the concrete layer omitted.

[0040] With reference to Figures 1 to 5 , the curtain wall panel 10 includes: a plurality of frame units 100, each of the frame units 100 having a hollow structure 101, the frame unit 100 including opposite first side portions 102 and second side portions 103, the second side portion 103 having an opening 104; wherein, the plurality of frame units 100 include a first frame unit 105 and a second frame unit 106, the first frame unit 105 extends along a first direction X and is arranged at intervals along a second direction Y, the second direction Y being perpendicular to the first direction X, the second frame unit 106 extends along the second direction Y and is arranged at intervals along the first direction X, and both ends of the second frame unit 106 are connected to the adjacent first frame unit 105; a concrete layer 200, located at the second side portion 103 of each of the frame units 100, and filling the hollow structure 101 of each of the frame units 100 through the opening 104.

[0041] In this embodiment, the frame unit 100 includes a long side and a short side, and the extending direction of the frame unit 100 is defined as the extending direction of the long side, that is, the length direction of the frame unit 100.

[0042] The frame unit 100 includes a first end and a second end along the length direction of the frame unit 100.

[0043] In this embodiment, the first frame unit 105 extends along the first direction X and is arranged at intervals along the second direction Y, the second frame unit 106 extends along the second direction Y and is arranged at intervals along the first direction X, the short side of the second frame unit 106 is connected to the long side of the first frame unit 105, and the first frame unit and the second frame unit 106 jointly form a frame assembly 120, and the first side portion 102 of each of the first frame units 105 and each of the second frame units 106 is the side facing the interior of the building, and the second side portion 103 is the side facing the exterior of the building.

[0044] Refer to Figure 4, in this embodiment, there is also a sealing strip 121 around the frame component 120, and the sealing strip 121 is in a C-shaped structure.

[0045] In this embodiment, the material of the sealing strip 121 is stainless steel.

[0046] In this embodiment, the functions of the sealing strip 121 are as follows: First, it makes it unnecessary to use a formwork when pouring the concrete layer on the second side wall 103; Second, it makes the formed curtain wall panel not easily damaged during transportation; Third, when connecting between curtain wall panels, it makes the compatibility of the sealant at the interface better.

[0047] In this embodiment, the hollow structure 101 of the frame unit 100 penetrates from the first end to the second end of the frame unit 100, and the opening 104 is communicated with the hollow structure 101.

[0048] In this embodiment, the material of the frame unit 100 is stainless steel.

[0049] In this embodiment, each second side portion 103 of the frame unit 100 has an opening 104, and the opening 104 faces the outdoor side. The concrete layer 200 is also formed on the outdoor side, that is, on each second side portion 103 of the frame unit 100. When pouring concrete to form the concrete layer, since the opening 104 is communicated with the hollow structure 101 of the frame unit 100, the concrete is simultaneously poured from the opening 104 into the hollow structure 101 of the frame unit 100, and the frame component 120 is integrally cast with the concrete layer to form an interlock, thereby forming a steel-concrete structure, which improves the strength and the stability of the force model.

[0050] In this embodiment, the first side portion 102 includes a long side and a short side. The long side is located on the long side of the frame unit 100, and the short side is located on the short side of the frame unit 100.

[0051] In this embodiment, the frame unit 100 further includes: a third side portion 107 and a fourth side portion 108, which are located between the first side portion 102 and the second side portion 103, and the third side portion 107 and the fourth side portion 10, respectively, are connected to the side edges of the first side portion 102.

[0052] In this embodiment, the third side portion 107 and the fourth side portion 108 are respectively connected to the long side of the first side portion 102.

[0053] In this embodiment, the first side portion 107 and the fourth side portion 108 are also respectively connected to the long side of the second side portion 103.

[0054] In this embodiment, the third side portion 107 and the fourth side portion 108 are parallel to each other and both are perpendicular to the first side portion 102 and the second side portion 103; in other embodiments, the third side portion 107 and the fourth side portion 108 may also be connected to the long side of the first side portion 102 non-parallelly.

[0055] In this embodiment, one or more openings 104 are provided on the second side portion 103 of the frame unit 100. The openings 104 are closed, and the openings 104 expose part of the first side portion 102.

[0056] In this embodiment, a plurality of openings 104 are provided on the second side portion 103. The openings 104 are elliptical, and the openings 104 are distributed at intervals on the second side portion 103. Each of the openings 104 exposes part of the first side portion 102.

[0057] In other embodiments, there may also be only one opening 104 on the second side portion 103, and the opening 104 exposes part of the first side portion 102.

[0058] In this embodiment, the concrete layer 200 is made of steel reinforced concrete, which has better toughness and better wind pressure resistance effect, thereby improving the performance of the formed curtain wall panel 10.

[0059] When the concrete layer 200 is made of steel reinforced concrete, the frame assembly 120 further includes: a steel bar network 109, and the steel bar network 109 is connected to the first side portion 102 of each frame unit 100.

[0060] In this embodiment, the steel bar network 109 includes a plurality of steel bars distributed along the first direction X and a plurality of steel bars distributed along the second direction Y; in other embodiments, it may also include only a plurality of steel bars distributed along the first direction X, or only a plurality of steel bars distributed along the second direction Y.

[0061] The steel bar network 109 can prevent the openings 104 from opening, thereby improving the strength of the formed frame assembly 120.

[0062] In other embodiments, the concrete layer 200 may also be made of high-strength concrete.

[0063] Reference Figure 2 , when the concrete layer 200 is made of high-strength concrete, the frame assembly 120 may not include a steel bar network either.

[0064] In this embodiment, the concrete layer 200 covers the second side portions 103 of the respective frame units 100, that is, covers the side of the frame assembly 120 facing the outdoors. At the same time, the hollow structure 101 of the frame unit 100 is filled through the opening 104, so that the strength and performance of the formed curtain wall panel 10 are improved. The concrete layer 200 and the frame assembly 120 complement each other in terms of rigidity and flexibility, forming a steel-concrete structure, preventing the problem of cracking of the concrete layer 200, and thus improving the quality of the formed curtain wall panel 10.

[0065] In this embodiment, the curtain wall panel 10 further includes: a filling layer 300, and the filling layer 300 is filled between adjacent first frame units 105 and between adjacent second frame units 106.

[0066] In this embodiment, the first frame unit 105 and the second frame unit 106 divide the frame assembly 120 into a plurality of grids, and the filling layer 300 is filled in the grids, and no additional connectors or adhesives are required to fix it in the grids, thereby reducing the use of connectors or adhesives, saving manufacturing costs. At the same time, due to the reduction in the use of adhesives, etc., the finally formed curtain wall panel 10 is more environmentally friendly, reducing the harm caused by chemical substances to human health.

[0067] In this embodiment, the filling layer 300 includes a first heat-insulating layer.

[0068] In this embodiment, the first heat-insulating layer is a heat-insulating board. The purpose of using the heat-insulating board is to make the formed curtain wall panel 10 lighter in weight, which is more conducive to use in the building assembly process; in other embodiments, the first heat-insulating layer can also be other heat-insulating materials.

[0069] In this embodiment, the purpose of the first heat-insulating layer is to enhance the performance of the curtain wall panel 10, that is, the abilities of waterproofing, fireproofing, and heat preservation.

[0070] The first heat-insulating layer can adopt a single-layer structure or a laminated structure.

[0071] Correspondingly, the first embodiment of the present invention also provides a composite curtain wall panel.

[0072] Reference Figure 6 , Figure 6 The cross-sectional view direction of Figure 5 is consistent with the cross-sectional view direction of

[0073] In this embodiment, the inner wall 20 adopts a single-layer structure and is made of environmentally friendly materials, on the one hand to protect the environment and on the other hand to ensure the safety of the residents.

[0074] In this embodiment, the inner wall 20 adopts an ALC board; in other embodiments, the inner wall 20 can also adopt a foamed concrete board, a foamed ceramic board, a clay board, etc., and one or more of them are laminated.

[0075] In this embodiment, the reason for adopting the ALC board for the inner wall 20 is that this material not only has good heat preservation performance but also has better heat insulation performance. When a reasonable thickness is adopted, it can be used not only in cold regions with high heat preservation requirements but also in areas with hot summers and cold winters or hot summers and warm winters with high heat insulation requirements, meeting the requirements of energy-saving standards.

[0076] In this embodiment, the second insulation layer 30 is located between the curtain wall board 10 and the inner wall 20, further enhancing the heat preservation performance of the formed composite curtain wall board.

[0077] In this embodiment, the material of the second insulation layer 30 is polyurethane. The polyurethane material has its own adhesiveness and does not require additional connectors or glue to connect it to the curtain wall board 10 and the inner wall 20, meeting the environmental protection requirements.

[0078] In other embodiments, the second insulation layer 30 can also adopt a thermal insulation board.

[0079] The first embodiment of the present invention also provides a forming process of a composite curtain wall board.

[0080] First, refer to Figure 1 , a plurality of frame units 100 are provided. The frame units 100 include a first frame unit 105 and a second frame unit 106. The first frame unit 105 extends along the first direction X and is arranged at intervals along the second direction Y. The second frame unit 106 extends along the second direction Y and is arranged at intervals along the first direction X. The two ends of the second frame unit 106 are connected to the adjacent first frame unit 105 to form a frame assembly 120.

[0081] In this embodiment, the short side of the second frame unit 106 is connected to the long side of the first frame unit 105.

[0082] In this embodiment, each of the frame units 100 has a hollow structure 101. Each of the frame units 100 includes opposite first side portions 102 and second side portions 103, and the second side portion has an opening 104.

[0083] In this embodiment, the first side portion 102 of each of the frame units 100 faces the interior, and the second side portion 103 faces the exterior.

[0084] In this embodiment, the opening 104 on the second side portion 103 is closed, exposing a part of the first side portion 102.

[0085] In this embodiment, it further includes: forming a steel bar network 109 on the first side portion 102 of each of the frame units 100, and the steel bar network 109 includes several steel bars parallelly distributed along the first direction X and steel bars parallelly distributed along the second direction Y.

[0086] In other embodiments, the steel bar network may not be formed.

[0087] Continue to refer to Figure 1 , a filling layer 300 is formed between adjacent first frame units 105 and between adjacent second frame units 106.

[0088] The filling layer 300 is a first heat-insulating layer. After the first heat-insulating layer is formed, the first heat-insulating layer is beneficial to improving the heat-insulating performance of the formed composite curtain wall panel.

[0089] In this embodiment, the first heat-insulating layer is a heat-insulating board.

[0090] Refer to Figure 3 and Figure 5 , a concrete layer 200 is poured and formed on the second side portion 103 of each of the frame units 100, and the concrete layer 200 also fills the hollow structure 101 of each of the frame units 100 through the opening 104.

[0091] In this embodiment, the opening 104 on the second side portion 103 of the frame unit 100 is closed, and the periphery of the opening 104 is surrounded by the second side portion 103. The concrete layer in the frame unit 100 is surrounded by the first side portion 102, the second side portion 103, the third side portion 107, and the fourth side portion 108 of the frame unit 100.

[0092] The frame assembly 120, the filling layer 300, and the concrete layer 200 form the curtain wall panel 10.

[0093] In this embodiment, since the concrete layer 109 has fluidity, when the concrete layer is poured, it will build into the hollow structure 101 of the frame unit 100 from the opening 104, thereby forming a steel-concrete structure and improving the strength and stress stability of the curtain wall panel 10.

[0094] Refer to Figure 6 , after the curtain wall panel 10 is formed, a second heat-insulating layer 30 and an inner leaf wall 20 are formed on the first side portion 102 of each of the frame units 100.

[0095] When the second heat-insulating layer 30 is a cast polyurethane heat-insulating layer, the second heat-insulating layer 30 is formed after the inner leaf wall 20 is formed.

[0096] Specifically, it includes: connecting the formed curtain wall panel 10 to the beam structure, clamping the inner leaf wall 20 between two upper and lower beams, and having the hollow layer between the inner leaf wall 20 and the curtain wall panel 10; then pouring polyurethane into the hollow layer to form a cast polyurethane heat-insulating layer. The polyurethane material itself has viscosity and connects the curtain wall panel 10 and the inner leaf wall 20, thereby forming the composite curtain wall panel.

[0097] When the second heat-insulating layer 30 is a heat-insulating board, the second heat-insulating layer 30 is formed before the inner leaf wall 20 is formed.

[0098] Specifically, it includes: connecting the formed curtain wall panel 10 to the beam structure, connecting the heat-insulating board to the side of the frame assembly 120 facing the interior through glue, connecting the formed curtain wall panel 10 to the beam structure, and then clamping the inner leaf wall 300 between two upper and lower beams, and connecting the inner leaf wall 300 to the heat-insulating board.
