Description

Technical Field

[0001] This utility model relates to the field of building curtain walls, and in particular to a curtain wall splicing unit. Background Technology

[0002] Aluminum panel curtain walls are widely used in engineering as a decorative and protective structure for building exterior walls. They have the characteristics of good rigidity, light weight, high strength, and corrosion resistance. When installing the outer curtain wall aluminum panels, in order to prevent the impact of thermal expansion and contraction on the structure, a pre-set distance joint is often left between the two curtain wall aluminum panels during the installation process.

[0003] In existing technologies, there are generally two ways to treat the seams. The first is to fill the seams with adhesive. However, on the one hand, the flexible adhesive filler is prone to collapse in the middle, affecting the flatness of the appearance. On the other hand, applying adhesive can easily contaminate the aluminum plate surface, affecting the consistency of the appearance. The second is to fill the seams with metal strips. However, on the one hand, due to the height difference between adjacent aluminum plates and between the aluminum plate and the metal strip, the transition cannot be smooth, affecting the flatness of the appearance. On the other hand, due to the deviation in aluminum plate processing and installation, it is difficult to ensure that the gaps are strictly left at the preset distance, resulting in inconsistent gaps in the filled metal strips, affecting the consistency of the appearance.

[0004] Therefore, there is an urgent need for a curtain wall splicing unit to solve the technical problem of poor flatness and consistency of the appearance at the splicing joints of aluminum panel curtain walls. Utility Model Content

[0005] This utility model provides a curtain wall splicing unit, which aims to solve the technical problem of poor flatness and consistency of appearance at the splicing points of aluminum panel curtain walls.

[0006] To solve the above-mentioned technical problems, the technical solution of this invention is as follows:

[0007] This utility model provides a curtain wall splicing unit, including:

[0008] The inner panel has a connector formed on one side for connection with the aluminum panel of the curtain wall;

[0009] The outer panel is connected to the inner panel by connecting ribs, and the width of the outer panel is greater than the preset width of the curtain wall joint;

[0010] An insertion cavity is formed between the outer panel and the inner panel, which is inserted into the edge of the curtain wall aluminum panel. The insertion cavity is located on both sides of the connecting rib.

[0011] Optionally, the connector includes:

[0012] A connecting plate, the connecting plate being formed on one side of the inner plate;

[0013] A fastening bolt is connected to the back side of the aluminum panel of the curtain wall. The end of the fastening bolt passes through a through hole on the surface of the connecting plate, and a fastening nut is threaded onto the end of the fastening bolt.

[0014] Optionally, multiple through holes and multiple fastening bolts are provided, and the multiple through holes and multiple fastening bolts are evenly distributed along the height direction of the curtain wall aluminum panel.

[0015] Optionally, the connecting plate abuts against the corresponding aluminum curtain wall panel.

[0016] Optionally, the insertion cavity includes a first insertion cavity and a second insertion cavity, the first insertion cavity being adjacent to the connecting plate, the inner width of the first insertion cavity being adapted to the thickness of the curtain wall aluminum plate, and the inner width of the second insertion cavity being greater than the thickness of the curtain wall aluminum plate.

[0017] Optionally, both the first and second insertion cavities are provided with sealing strips, and the edge of the curtain wall aluminum panel abuts against the sealing strips.

[0018] Optionally, the inner panel has a first chamfer formed on its edge, and the first chamfer is located inside the second insertion cavity to guide the curtain wall aluminum panel into the second insertion cavity.

[0019] Optionally, the outer plate has a second chamfer and a third chamfer formed at both ends, the second chamfer and the third chamfer being respectively away from the first insertion cavity and the second insertion cavity.

[0020] Optional, also includes:

[0021] A corrosion-resistant coating is uniformly applied to the outer surface of the outer panel.

[0022] The above-described solution of this utility model has at least the following beneficial effects:

[0023] The inner panel of this invention connects to the aluminum curtain wall panel from the inside, improving the stability of the connection. The outer panel covers the curtain wall seam from the outside. The connecting ribs form an insertion cavity in the spatial structure of the inner and outer panels. The insertion cavity is used to connect with the edge of the aluminum curtain wall panel. The insertion cavity is located on both sides of the connecting ribs to form a circular connection unit. The number of aluminum curtain wall panels can be freely adjusted according to the area requirements of the building curtain wall, improving the flexibility of application. Since the width of the outer panel is greater than the preset width of the curtain wall seam, only the outer panel covering the seam is visible when viewed from the outside in, achieving the effect of complete coverage of the curtain wall seam. Furthermore, because the outer panels are all of uniform size, the technical problem of poor flatness and consistency at the aluminum panel curtain wall seam is solved. This invention solves the technical problem of poor flatness and consistency at the aluminum panel curtain wall seam by using outer panels of the same size and with a flat surface to cover the seam.

[0029] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0030] like Figures 1-3 As shown, an embodiment of this utility model proposes a curtain wall splicing unit, comprising:

[0031] Inner panel 2, one side of which is formed with a connector for connecting to the curtain wall aluminum panel 6;

[0032] Outer panel 1, which is connected to inner panel 2 by connecting rib 3, and the width of outer panel 1 is greater than the preset width of curtain wall joint;

[0033] An insertion cavity is formed between the outer panel 1 and the inner panel 2, which is inserted into the edge of the curtain wall aluminum panel 6. The insertion cavity is located on both sides of the connecting rib 3.

[0034] In this embodiment, in view of the fact that the existing technology for treating curtain wall seams cannot maintain good flatness and consistency, this application provides the connecting rib 3 between the inner panel 2 and the outer panel 1. The two sides of the connecting rib 3 are formed into insertion cavities at the edges of the curtain wall aluminum panel 6. The edges of the curtain wall aluminum panel 6 are used to insert and cooperate with the insertion cavities to form a cyclically connected curtain wall seam unit.

[0035] The inner panel 2 is used to connect to the curtain wall aluminum panel 6 from the inside, improving the stability of the connection. The outer panel 1 is used to cover the curtain wall joints from the outside. The connecting rib 3 is used to cooperate with the spatial structure of the inner panel 2 and the outer panel 1 to form an insertion cavity. The insertion cavity is used to connect with the edge of the curtain wall aluminum panel 6. The insertion cavity is located on both sides of the connecting rib 3 to form a circular connection unit. The number of curtain wall aluminum panels 6 can be freely adjusted according to the area requirements of the building curtain wall, improving the flexibility of application.

[0036] Since the width of the outer panel 1 is greater than the preset width of the curtain wall joint, when viewed from the outside in, only the outer panel 1 used to cover the joint can be seen, thus achieving the effect of the outer panel 1 completely covering the curtain wall joint. Furthermore, since the dimensions of the outer panel 1 are completely consistent, the technical problem of poor flatness and consistency of the appearance at the joint of the aluminum panel curtain wall is solved.

[0037] like Figure 1 As shown, in an optional embodiment of the present invention, the connector includes:

[0038] Connecting plate 21, the connecting plate 21 being formed on one side of the inner plate 2;

[0039] Fastening bolt 23 is connected to the back side of the aluminum panel 6 of the curtain wall. The end of the fastening bolt 23 passes through the through hole 22 on the surface of the connecting plate 21, and the end of the fastening bolt 23 is threaded with a fastening nut 24.

[0040] In this embodiment, the connecting plate 21 is formed on one side of the inner plate 2, providing installation space for the connection operation. The fastening bolt 23 is connected to the back side of the curtain wall aluminum plate 6 to achieve the connection function from the inside. The through hole 22 is engaged with the end of the fastening bolt 23 to provide positioning. The end of the fastening bolt 23 is threaded with a fastening nut 24, which is used to lock the fastening bolt 23, further improving the stability of the structure.

[0041] like Figure 1 As shown, in an optional embodiment of the present invention, multiple through holes 22 and multiple fastening bolts 23 are provided, and the multiple through holes 22 and multiple fastening bolts 23 are evenly distributed along the height direction of the curtain wall aluminum plate 6.

[0042] In this embodiment, the through holes 22 and the fastening bolts 23, which are evenly distributed along the height direction, form a multi-point force-bearing system, enabling the load of the curtain wall aluminum panel 6 to be evenly transferred to the main structure, effectively avoiding stress concentration and significantly improving the overall wind pressure resistance and seismic performance of the curtain wall system. Furthermore, the evenly distributed through holes 22 form a positioning reference, which reduces alignment errors during construction and increases assembly speed. Moreover, the evenly distributed through holes 22 and the fastening bolts 23 share the deformation of the connecting plate 21 under temperature deformation and structural displacement, improving the stability of the structure.

[0043] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the connecting plate 21 abuts against the corresponding curtain wall aluminum plate 6.

[0044] In this embodiment, the connecting plate 21 abuts against the corresponding aluminum curtain wall plate 6 to reduce the gap between the connecting plate 21 and the corresponding aluminum curtain wall plate 6, thereby further improving the stability of the structure.

[0045] like Figure 1 As shown, in an optional embodiment of the present invention, the insertion cavity includes: a first insertion cavity 4 and a second insertion cavity 5. The first insertion cavity 4 is adjacent to the connecting plate 21. The inner width of the first insertion cavity 4 is adapted to the thickness of the curtain wall aluminum plate 6. The inner width of the second insertion cavity 5 is greater than the thickness of the curtain wall aluminum plate 6.

[0046] In this embodiment, the first insertion cavity 4 is used to connect and fix the first side of the curtain wall aluminum panel 6, and the second insertion cavity 5 is used to connect the second side of the adjacent curtain wall aluminum panel 6. The connection process between the first insertion cavity 4 and the curtain wall aluminum panel 6 is completed in the factory, so the inner width of the first insertion cavity 4 is adapted to the thickness of the curtain wall aluminum panel 6 to improve the stability of the connection. The connection process between the second insertion cavity 5 and the curtain wall aluminum panel 6 is completed on the construction site, so the inner width of the second insertion cavity 5 is greater than the thickness of the curtain wall aluminum panel 6 to improve the error tolerance of the construction process.

[0047] like Figure 1 As shown, in an optional embodiment of the present invention, both the first insertion cavity 4 and the second insertion cavity 5 are provided with sealing strips, and the edge of the curtain wall aluminum plate 6 abuts against the sealing strips.

[0048] In this embodiment, by setting the sealing strip in the first insertion cavity 4 and the second insertion cavity 5, the penetration path of media such as air and rainwater can be effectively blocked, thereby enhancing the airtightness and watertightness of the curtain wall system, reducing the risk of leakage, and ensuring the stability of the internal environment of the curtain wall aluminum panel 6. The edge of the curtain wall aluminum panel 6 abuts against the sealing strip, which on the one hand uses the elastic compression characteristics of the sealing strip to buffer the contact stress between the curtain wall aluminum panel 6 and the insertion cavity, and on the other hand, the sealing strip helps to fix the position of the aluminum panel, prevents the panel from sliding or loosening laterally, and further improves the stability of the connection.

[0049] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the inner panel 2 has a first chamfer 25 formed on its edge, and the first chamfer 25 is located in the second insertion cavity 5 to guide the curtain wall aluminum panel 6 into the second insertion cavity 5.

[0050] In this embodiment, the first chamfer 25 formed in the second insertion cavity 5 is used to increase the opening area of ​​the second insertion cavity 5, so as to guide the curtain wall aluminum panel 6 to be inserted into the second insertion cavity 5 more easily, thereby improving the convenience of the installation process.

[0051] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the outer plate 1 has a second chamfer 11 and a third chamfer 12 formed at both ends, and the second chamfer 11 and the third chamfer 12 are respectively far away from the first insertion cavity 4 and the second insertion cavity 5.

[0052] In this embodiment, the two ends of the outer panel 1 are formed with a second chamfer 11 and a third chamfer 12, and the second chamfer 11 and the third chamfer 12 are respectively far away from the first insertion cavity 4 and the second insertion cavity 5, so as to form a smooth transition between the outer panel 1 and the curtain wall aluminum panel 6, reduce rigid collisions, and extend service life.

[0053] In an optional embodiment of this utility model, it further includes:

[0054] An anti-corrosion treatment layer is uniformly applied to the outer surface of the outer panel 1.

[0055] In this embodiment, the anti-corrosion treatment layer is used to isolate the outer surface of the outer panel from the external environment, slow down the corrosion rate of the outer surface of the outer panel, and improve the durability of the outer panel.

[0056] like Figure 3 As shown, in this project, the installation of the aluminum curtain wall panels is supported by columns and installation frames on both sides. Finally, the aluminum curtain wall panels are installed on the outermost side of the building structure to form the curtain wall appearance. The connection process between the first insertion cavity 4 and the aluminum curtain wall panel 6 is completed in the factory; the connection process between the second insertion cavity 5 and the aluminum curtain wall panel 6 is completed on the construction site, which simplifies the installation process and improves convenience and reliability.

[0057] This invention solves the technical problem of poor flatness and consistency at the joints of aluminum panel curtain walls by using an outer panel of the same specification and with a flat surface to cover the seams.

[0058] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
