[0038] Please refer to the attached Figures 1 to 5 as well as Figure 17 The present invention provides a shaped curtain wall 100 without bending and twisting keels, which belongs to a unit-type shaped glass curtain wall. The decorative aluminum plate 8 of the shaped curtain wall 100 is formed as a whole by two curved "K" shapes connected back to back. The back molding line of the "K" shape is formed by the intersection of a vertical cylinder and a horizontal elliptical cylinder (such as Figure 1 and Figure 2The edge of the decorative aluminum plate 8 is a three-dimensional spline curve. In order to achieve the function of replacing the curtain wall glass 9 in the future, the curtain wall glass 9 cannot be embedded in the decorative aluminum plate 8. Therefore, the glass needs to be cut along the three-dimensional spline curve, and the corresponding glass support keel needs to be bent along the three-dimensional spline curve. However, the current industry technology level is difficult to achieve the production of accurate bending and twisting keels along the three-dimensional spline curve (such as Figure 18 As shown in the figure, the present invention uses several profiles to "hand in hand" spliced together to form a cylindrical surface, and then cut along a three-dimensional spline curve through a milling process. The following is a detailed description of the shaped curtain wall with no bending and twisting keels provided by this embodiment in conjunction with the accompanying drawings.
[0039] See attached picture Figure 9 and Figure 17 , which is a schematic structural diagram of a non-bending and twisting keel curtain wall provided in this embodiment. The non-bending and twisting keel curtain wall 100 provided in this embodiment includes a crossbeam 1, columns 2, and curved splicing components 3. The columns 2 are each fixed to the main structure 4 of the building. The crossbeam 1 is fixed to the columns 2.
[0040] See attached Figures 12 to 16 The arc-shaped splicing assembly 3 is installed at the upper end and / or lower end of the beam 1, and the left and right ends of the arc-shaped splicing assembly 3 are respectively fixed to a column 2. In other words, the arc-shaped splicing assembly 3 can be fixed to the upper end of the beam 1 or the lower end of the beam 1, and the specific shape can be determined according to the curtain wall shape. The arc-shaped splicing assembly 3 includes a plurality of aluminum alloy profiles 5 with a rectangular cross-section. The aluminum alloy profile 5 includes a first end face 51, a second end face 52, a third end face 53, and a fourth end face 54. The first end face 51, the second end face 52, the third end face 53, and the fourth end face 54 together enclose a rectangular structure.
[0041] The inner cavity of the aluminum alloy profile 5 is provided with a plurality of mounting nail holes 55. The aluminum alloy profile 5 is secured to the crossbeam 1 via a plurality of framing nails 6, with each set of framing nails 6 corresponding to a mounting nail hole 55. In this embodiment, each aluminum alloy profile 5 has two mounting nail holes 55: one located at the corner connecting the first end and the second end surface 52, and the other located on the third end surface 53. The two mounting nail holes 55 are arranged slightly diagonally.
[0042] A latching protrusion 56 is provided at each end of the first end face 51, and a latching recess 57 is provided at each end of the third end face 53. The two latching recesses 57 and the third end face 53 enclose a notch, which gradually shrinks from the inside to the outside, and the two latching protrusions 56 can be snapped into the notch. The arc-shaped splicing assembly 3 is assembled by mutually snapping together a plurality of aluminum alloy profiles 5 through the latching recesses 57 and the latching protrusions 56. The use of mechanical snapping between the plurality of aluminum alloy profiles 5 can increase the reliability of the assembly frame. Glueing notches can be provided at the splicing locations for applying sealant 58 to ensure the sealing reliability of the profile splicing locations. As shown in the figure, the latching protrusions 56 are inclined relative to the first end face 51, and the two latching protrusions 56 are in an inverted "eight" shape relative to the first end face 51, so that they can be snapped into the notch enclosed by the two latching recesses 57 and the third end face 53. It is understandable that when the latching protrusion 56 is latched in the notch, there is a certain margin between the two, so that the plurality of aluminum alloy profiles 5 can be spliced into the desired arc shape.
[0043] L-shaped mounting grooves 59 are projecting outward from both ends of the fourth end surface 54, with the two mounting grooves 59 facing each other. A rectangular aluminum alloy glass retainer 7 is provided on the outside of the aluminum alloy profile 5, corresponding to the fourth end surface 54. A retainer 7 is provided on the end surface of the aluminum alloy profile 5 facing the retainer. The retainer 7 is secured within the mounting grooves 59 and secured with screws 71.
[0044] The end surfaces of the curved splicing assembly 3 and the aluminum alloy glass clamp 7 are milled to form a three-dimensional spline curve. For example, when the bottom end of the curved splicing assembly 3 is fixed to the crossbeam 1, the top surfaces of the curved splicing assembly 3 and the aluminum alloy glass clamp 7 are milled to form a three-dimensional spline curve. Conversely, when the top end of the curved splicing assembly 3 is fixed to the crossbeam 1, the bottom surfaces of the curved splicing assembly 3 and the aluminum alloy glass clamp 7 are milled to form a three-dimensional spline curve. Curtain wall glass 9, which matches the shape of this three-dimensional spline curve, is affixed to the aluminum alloy glass clamp 7.
[0045] The ends of the curtain wall glass 9 can be integrally formed with multiple inserts 91, which are inserted into the corresponding cavities of the aluminum alloy glass retainer 7. The inserts 91 have a shape that matches the cavity of the aluminum alloy glass retainer 7, allowing them to be inserted into the cavity of the aluminum alloy glass retainer 7, and are cushioned and sealed by gaskets 92 and seals 93. This description only focuses on the mounting surface of the curtain wall glass 9 and the aluminum alloy glass retainer 7. The other mounting surfaces of the curtain wall glass 9, such as those mounted on the beams 1 or columns 2, can use conventional mounting methods and will not be further described here.
[0046] The outer side of the arc-shaped splicing component 3 is installed with a decorative aluminum plate 8, and the left and right ends of the decorative aluminum plate 8 are fixed to the pillars 2. Figure 9, decorative aluminum plate 8 covers the arc splicing component 3. It can be understood that the outer side of the arc splicing component 3 is covered with a decorative aluminum plate 8, and the surface of the column 2 and the aluminum alloy glass card code 7 is also covered with a layer of decorative aluminum plate 8, which plays a better decorative role.
[0047] See attached Figures 6 to 8 、 Figure 10 、 Figure 11 The shaped curtain wall 100 further includes a glass sunshade structure 10. The glass sunshade structure 10 is located between upper and lower adjacent curtain wall glass panels 9. The glass sunshade structure includes a glass support 11 and a sunshade glass 12. The glass support 11 is fixed to the column 2, and the sunshade glass 12 is fixed to the glass support 11.
[0048] In summary, the shaped curtain wall without bending and twisting keels provided by the present invention replaces traditional bending and twisting keels by splicing profiles, has simple processing and installation processes, and meets the requirements of complex three-dimensional modeling.
[0049] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
