DETAILED DESCRIPTION

[0016] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to be able to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0017] See also Figure 1 and Figure 2 The method for constructing a curved special-shaped square tube background wall according to an embodiment of the present invention comprises the following steps: Step 1: Divide a single aluminum square tube into three sections according to the preset background wall rendering: the upper section straight square tube 1, the lower section straight square tube 3 and the middle section curved special-shaped square tube 2, and number them respectively.

[0018] Specifically, since the length of some curved special-shaped square tubes is relatively long in practice, for example, 5 meters, the entire curved special-shaped square tube cannot be twisted, and the twisting position of each aluminum square tube in the entire curved special-shaped square tube background wall is different, and the overall smoothness and curvature cannot be accurately judged. In view of this, the embodiment of the present invention divides a single aluminum square tube into segments according to the curves in the preset background wall rendering.

[0019] In specific implementation, the quadratic curve y=ax is used 2 +bx+c and the cubic curve y= a′x 3 + b′x 2+ c′x+ d′ to draw the curves representing the special-shaped square tube surface in the preset background wall effect diagram, and adjust their positions and shapes to edit the curves to match the preset background wall effect diagram. Figure 1 According to the two final confirmed curves ( Figure 2 The upper and lower curves are the dividing lines between the upper straight square tube 1 and the lower straight square tube 3, and the dividing line between the middle curved special-shaped square tube 2 and the lower straight square tube 3). The curved special-shaped square tube is divided into three sections: the upper straight square tube 1, the lower straight square tube 3 and the middle curved special-shaped square tube 2. Among them, the NURBS curve tool of 3Dmax software can be used to input the quadratic curve y=ax 2 +bx+c, cubic curve command a′x 3 + b′x 2 + c′x+ d′ to draw these irregular curves by three-dimensional lofting. The preset background wall effect diagram in this embodiment is determined according to needs and is not limited here.

[0020] Furthermore, a section of the initial curve is randomly selected, and a coordinate axis is established at one point of the section; then 3 or 4 points are randomly selected on the selected section of the curve and substituted into the corresponding curve function expression to calculate the coefficients a, b, c and a', b', c', d', and the curvature of each selected point is checked to see whether it is consistent with the initial curve, and the coefficients a, b, c and a', b', c', d' are adjusted until the selected section of the curve is consistent with the effect. Figure 1 Follow this step to analyze all curve segments of the entire curve to ensure the smoothness of the entire curve.

[0021] Take point A on curve segment L as an example and establish the coordinate axis. Figure 2 Check whether the curvature of point A enlarged in the figure is consistent with the curve segment L. According to this method, 3-4 points are obtained to obtain the quadratic curve y=ax 2 +bx+c coefficient parameters a, b, c and the cubic curve y=ax 3 +bx 2 +cx+d coefficient parameters a′, b′, c′, d′, ensure the curve and effect Figure 1 Follow this step to analyze all curve segments of the entire curve, and finally check the smoothness of the entire curve to avoid curve faults. Figure 2 The x-axis and y-axis coordinates of the torsion point of the Chalco square tube can also be reflected through the coordinate system later, and the marking here is only for reference).

[0022] In this embodiment, the curved special-shaped aluminum square tube is intended to be modeled as a whole by Rhino software, and the structural models of aluminum square tubes of several sizes such as 50mm×120mm, 40mm×120mm, 30mm×120mm, etc. are placed in the Rhino software torsion angle for analysis respectively. For example, an aluminum square tube of size 30mm×120mm (width and length of the cross section) can be selected for use.

[0023] Step 2, determining the torsion position and torsion angle of the middle section curved special-shaped square tube.

[0024] Specifically, the length of the middle section of the curved special-shaped square tube of each aluminum square tube is equal, and the twist angle is also the same. In this embodiment, the length of the middle section of the curved special-shaped square tube of each aluminum square tube is 2m. In order to ensure the beauty of the pattern, the twisting position of the middle section of the curved special-shaped square tube is located in the middle part, and the twisting angle can be 90°. Of course, any position and any angle can be selected for twisting according to needs.

[0025] In order to reduce the rework loss caused by the number of angle positions confirmed on site, the middle section of the curved special-shaped square tube is defined as an identical component through on-site installation of the sample section. After uniformly processed in the factory, it is transported to the site for installation. The molding accuracy is greatly improved, while saving construction time and ensuring one-time molding.

[0026] Step 3, rotate the upper straight square tube of each aluminum square tube clockwise or counterclockwise to a first preset angle, rotate the lower straight square tube in the opposite direction of the upper straight square tube to a second preset angle, and then position and install the two straight square tubes to a preset position, and weld the upper straight square tube, the lower straight square tube and the middle curved special-shaped square tube of each aluminum square tube to form a whole.

[0027] Specifically, the first preset angle and the second preset angle are equal. Preferably, the first preset angle and the second preset angle are both 45°. In this embodiment, the curved special-shaped square tube can be mass-produced in upper and lower sections to reduce mold opening costs.

[0028] Combination Figure 3 and Figure 4, more specifically, the upper straight square tube and the lower straight square tube are installed to the preset position by the first latch 4 and the second latch 5. Wherein: the first latch is U-shaped; and / or the second latch is in the shape of a figure "J". In this embodiment, a "U-shaped" and "figure "shaped" fixing devices are designed for the upper and lower parts of the curved special-shaped aluminum square tube for sleeve connection, which is convenient for later maintenance and replacement. The upper "U-shaped" fixing device is a galvanized iron sheet with a length of 145mm, a width of 25mm, and a height of 30mm, and a thickness of 3mm. The lower "figure "shaped" fixing device is a galvanized iron sheet with a length of 145mm, a width of 25mm, and a height of 30mm, and a thickness of 3mm. The lower "figure "shaped" fixing device is a galvanized iron sheet with a length of 145mm, a width of 25mm, and a height of 30mm, and a thickness of 3mm with 25mm wings on both sides.

[0029] More specifically, the upper straight square tube can be detachably connected to the ceiling base layer through a U-shaped first latch; the lower straight square tube can be detachably connected to the floor layer through a "X"-shaped latch.

[0030] In practice, after the curved special-shaped aluminum square tubes arrive at the site, they need to be selected according to each number, especially the curved special-shaped aluminum square tubes have front and back sides when installed. If the installation direction is wrong, the wave line cannot extend smoothly and the effect of software simulation cannot be achieved. After confirmation, the curved special-shaped aluminum square tubes are plugged in and fixed up and down. At this time, it is especially necessary to pay attention to the interference of the curved special-shaped square tubes themselves. First connect the upper "U-shaped" accessory end, and then use its interference to cover the lower part of the "J-shaped" accessory. Later, the lower part can be pulled out first, and then repaired, replaced, cleaned, and wiped for easy use.

[0031] It can be obviously concluded from the above that the construction method of the curved special-shaped square tube background wall provided in this embodiment, by segmenting the aluminum square tube, and after determining the torsion position and torsion angle of the middle segment curved special-shaped square tube, the upper straight square tube and the lower straight square tube are installed to the preset position and then the three are welded together, which greatly reduces the rework rate and improves the construction efficiency, which is conducive to large-scale promotion and utilization.

[0032] In addition, the present invention uses latch-type accessories to install and fix the aluminum square tube, which not only displays rich forms and shapes and increases the aesthetics of the building, but also facilitates disassembly, maintenance, cleaning and wiping during later use, making the construction process more convenient.

[0033] In summary, the present invention has the following beneficial effects: 1. Compared with the traditional grille background wall, it can be customized according to the design requirements and style of the building. It can be modeled through Rhino software, and the torsion angles can be analyzed separately in Rhino software. The torsion angles and torsion positions of the aluminum square tubes can be adjusted to simulate the torsion angles and torsion positions of different modeling effects, which can show rich forms and shapes and increase the beauty of the building.

[0034] 2. It has strong stability and adopts latch-type upper and lower end fixing devices to ensure that the curved special-shaped aluminum square tube can achieve the desired effect. At the same time, it is easy and convenient to disassemble, can be reused, and is relatively easy to maintain.

[0035] 3. It has strong plasticity and can be made into special shapes according to needs to meet the needs. The entire curved special-shaped aluminum square tube is processed and twisted in the factory and sprayed with wood grain color before being transported to the site for installation. The overall construction time is greatly shortened and the molding effect is good.

[0036] 4. On-site construction is efficient, fast and well managed, and the systematic installation system has better safety guarantees.

[0037] 5. The curved structure can reduce direct sunlight, which can reduce the direct sunlight into the room to a certain extent, reduce the heat radiation of sunlight to the room, and achieve energy-saving effect.

[0038] The above advantages can be realized while the curved special-shaped aluminum square tube background wall system meets the design effect, and the construction technology plan can be implemented, which is conducive to promotion.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
