Description

Technical Field

[0001] The present invention relates to a building curtain wall and a manufacturing method of its panel, and more specifically, to an aluminum plate curtain wall imitating tortoise grain stone and a manufacturing method of its aluminum single plate. Background Art

[0002] In the prior art, the construction party and architects have higher and higher requirements for the quality of the building curtain wall panel. As a panel with a unique crack style, tortoise grain stone has a special architectural imprint and is more and more popular among people. However, tortoise grain stone is relatively heavy, difficult to install, and prone to falling, causing safety accidents. Moreover, the stone raw materials are limited by space and time, with high costs and difficult to industrialize production. How to fully retain the advantages of tortoise grain stone and minimize its disadvantages is a problem that building curtain wall designers need to solve currently. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an aluminum plate curtain wall imitating tortoise grain stone and a manufacturing method of its aluminum plate, which can be industrially produced, have low costs, and are easy to install.

[0004] The technical solution of the present invention is as follows: An aluminum plate curtain wall imitating tortoise grain stone includes more than one panel unit. The panel unit uses an aluminum plate. The outer surface of each panel unit is composed of several plates with polygonal boundaries to form a tortoise grain shape. Each adjacent two plates share a convex edge, and a groove is planed at the corresponding position of the inner surface of the panel unit with respect to the convex edge.

[0005] The depth of the groove is 1 / 4 to 1 / 2 of the thickness of the aluminum plate.

[0006] A reinforcing rib is welded and fixed on the back surface of the panel unit, and the bottom surface of the reinforcing rib matches the shape of the back surface of the panel unit and fits each other.

[0007] More than two of the panel units are spliced into a larger curtain wall panel. The convex edges at the splicing edge of two adjacent spliced panel units are butt-jointed with each other, and the outer surfaces of two adjacent panel units at the splicing position are aligned, so that the plates at the splicing position of the two panel units are spliced into a larger plate.

[0008] The periphery of the panel unit has a bent edge. Two adjacent bent edges of adjacent panel units are respectively fixedly connected to a plug-in male profile and a plug-in female profile. The plug-in male profile is fixedly connected to a support with screws, and the plug-in head provided at the outer end of the plug-in male profile is inserted into the slot provided on the female profile.

[0009] The manufacturing method of the aluminum plate imitating tortoise grain stone of the present invention includes the following steps:

[0010] Step 1: Project the designed moiré pattern onto the back of the aluminum plate and draw the lines. These lines form a moiré pattern consisting of several polygons, and each adjacent pair of polygons shares a common edge.

[0011] Step 2: Groove along the drawn lines on the back of the aluminum plate.

[0012] Step 3: Prepare a mold whose bottom surface has the designed three-dimensional moiré pattern.

[0013] Step 4: Place the aluminum plate with grooves on the back opposite to the bottom surface of the mold, and align the grooved positions with the polygon lines of the moiré pattern on the bottom surface of the mold. Press the aluminum plate towards the bottom surface of the mold so that the shape of the aluminum plate matches the shape of the bottom surface of the mold.

[0014] In Step 2, the depth of the groove on the back of the aluminum plate is 1 / 4 to 1 / 2 of the thickness of the aluminum plate.

[0015] After Step 4, it further includes Step 5: Weld reinforcing ribs on the back of the aluminum plate, and make the bottom surface of the reinforcing ribs match and fit well with the shape of the back of the aluminum plate.

[0016] After Step 4, it further includes

[0017] Step 6: Repair the cracks on the aluminum plate caused by extrusion with filler.

[0018] Step 7: Spray paint on the surface of the aluminum plate.

[0019] In Step 4, a hydraulic press is used for pressing the mold. The pressing time is until the starting point of the loading curve coincides with the ending point of the unloading curve and the residual deformation is reduced to zero.

[0020] Compared with the prior art, the aluminum plate curtain wall imitating moiré stone of the present invention has a simple structure, a realistic effect, and the patterns, colors, etc. can be adjusted arbitrarily. It is easy for industrial production, the raw materials are no longer restricted by space and time, the cost is much lower than that of natural moiré stone, and it has many advantages such as simple installation, not easy to fall, safe and durable, and convenient replacement.

[0025] The present invention will be further described in detail below in conjunction with embodiments and drawings.

[0026] As Figure 1 shown, the aluminum plate curtain wall imitating tortoise grain stone of the present invention includes one or more panel units 1, which are installed outside the curtain wall cross beam 5. The curtain wall cross beam 5 can be welded and fixed to an angle steel 6, and the angle steel 6 is welded and fixed to a plate type embedded part 7 embedded in the building wall.

[0027] As Figure 2 and Figure 3 shown, the panel unit 1 is made of aluminum plate. The outer surface of each panel unit 1 is composed of several plates 11 with polygonal boundaries to form a tortoise grain shape. The plate 11 can be convex, concave, flat or any other shape, and the number of sides of the polygonal boundary is not limited. In this embodiment, the boundaries of some plates 11 are pentagons and the boundaries of some plates 11 are hexagons. Each adjacent two plates 11 share a convex edge 12. Correspondingly, a groove 13 is cut at the position corresponding to the convex edge 12 on the inner surface of the panel unit 1. The groove 13 helps the aluminum plate to be die-pressed to form the required tortoise grain shape.

[0028] In some embodiments, two or more of the panel units 1 are spliced together in a transverse or longitudinal or other form to form a curtain wall panel with a larger area. Among them, the convex edges 12 at the splicing edges of two adjacent spliced panel units 1 are butted against each other, and the outer surfaces of two adjacent panel units 1 are aligned at the splicing position, so that the plates 11 at the splicing position of the two panel units 1 are spliced into a larger plate.

[0029] In order to enable the panel unit 1 to maintain the tortoise grain shape for a long time and reliably, as Figure 4 shown, at least one reinforcing rib 14 is welded and fixed to the back surface of each panel unit 1. The bottom surface of the reinforcing rib 14 opposite to the panel unit 1 is designed to match the shape of the back surface of the panel unit 1, so that the bottom surface of the reinforcing rib 14 fits with the back surface of the panel unit, and the reinforcing rib 14 is welded to the back surface of the panel unit 1 at multiple points along its length direction.

[0030] For the convenience of connection and increased strength, the periphery of the panel unit 1 has a bent edge 15 bent backward, as Figure 1As shown in the figure, a male insertion profile 2 is riveted and fixed to the right bending edge 15 of the left panel unit 1. The outer end of the male insertion profile 2 is provided with a plug connector 21. The middle part of the male insertion profile 2 is fixedly connected to a support 4 by screws, and the support 4 is welded and fixed to the angle steel 6. A female insertion profile 3 is riveted and fixed to the left bending edge 15 of the right panel unit 1. The outer end of the female insertion profile 3 is provided with a slot 31. The plug connector 21 of the male insertion profile 2 is inserted into the slot 31 of the female insertion profile 3, thereby realizing the connection of adjacent left and right panel units 1.

[0031] The panel unit 1 can be made of an aluminum plate with a thickness of 2 - 3 mm. When the plate thickness is 2 mm, the grooving depth is 1 - 0.2 mm. When the plate thickness is 2.5 - 3 mm, the grooving depth is 1.6 - 0.2 mm. Preferably, the grooving depth is 1 / 4 to 1 / 2 of the aluminum plate thickness, and the grooving depth does not exceed half of the aluminum plate thickness. The angle of the V-shaped groove is preferably 1.5 - 2.5 degrees larger than the actual forming angle because the cold bending forming of metal materials will have rebound, and the reserved margin is convenient for controlling the angle during processing. In this embodiment, the panel unit 1 is made of an aluminum plate with a thickness of 3 mm, a length of 1000 mm, a height of 1200 mm, and a grooving depth of 1 mm.

[0032] The manufacturing method of the aluminum plate imitating tortoise-shell stone of the present invention includes the following steps:

[0033] Step 1: Project the designed tortoise-shell pattern and draw lines on the back of the aluminum plate. These lines are composed of several polygons to form a tortoise-shell pattern, and each adjacent two polygons share a common side.

[0034] Step 2: Groove along the drawn lines on the back of the aluminum plate. The grooving depth is 1 / 4 to 1 / 2 of the aluminum plate thickness, and the angle of the V-shaped groove is 1.5 - 2.5 degrees larger than the actual forming angle.

[0035] Step 3: Prepare a mold. The bottom surface of the mold has the designed three-dimensional tortoise-shell pattern. The mold can be a convex mold or a concave mold, and the material is a mold steel without carbide segregation, such as: 8503, LG, 8566.

[0036] Step 4: Oppose the aluminum plate with grooves on the back to the bottom surface of the mold, and the grooving position corresponds to the polygon lines of the tortoise-shell pattern on the bottom surface of the mold. Press the aluminum plate towards the bottom surface of the mold so that the shape of the aluminum plate matches the shape of the bottom surface of the mold. The pressure during pressing varies depending on the shape of the aluminum plate. In this embodiment, a 160T hydraulic press is used for pressing, and the pressing time is until the starting point of the loading curve coincides with the ending point of the unloading curve, and the residual deformation is reduced to zero.

[0037] Step 5: Weld a reinforcing rib on the back of the aluminum plate. The shape of the bottom surface of the reinforcing rib matches and fits the shape of the back of the aluminum plate. The reinforcing rib can be formed by bending an aluminum alloy plate.

[0038] Step Six: Use fillers such as aluminum alloy repair agent or epoxy resin glue to repair the cracks generated on the aluminum plate due to extrusion.

[0039] Step Seven: After grinding the aluminum plate in Step Six, paint is sprayed on its surface. The paint can be a commonly used paint with strong adhesion, good flexibility, and the ability to adapt to changes in concave and convex shapes.

[0040] If hemming is required around the aluminum plate, it can be carried out before the grooving in Step Two. The aluminum plate imitating tortoise-shell pattern stone of the present invention can be made through the above steps.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
