Description

Technical Field

[0001] This utility model relates to the field of architectural decorative door technology, and in particular to a non-slip embedded cast aluminum door structure. Background Technology

[0002] Existing cast aluminum doors are mainly divided into two categories: snap-fit ​​doors and flat-fit doors without snap-fit ​​edges.

[0003] The patent with publication number CN218934223U discloses a door frame structure that uses aluminum alloy profiles as the frame to fix the outer aluminum trim of the door leaf. However, it requires custom-made aluminum alloy profiles and additional profile installation, resulting in high production costs and complex processing technology. Furthermore, the frame will cause raised borders around the door leaf trim, which will disrupt the overall look of the door leaf and result in poor appearance simplicity.

[0004] The patent with publication number CN219299123U discloses a non-slip flat-fit structure that uses an aluminum plate flat-fit process to directly glue the door core and aluminum trim to the door panel with silicone structural adhesive. However, obvious process seams are likely to appear on the side of the door leaf, and glue overflow is likely to occur between the door core and the aluminum trim. Additional manual labor is required to handle the seams and glue overflow, which increases labor time and cost, and the appearance defects are difficult to completely eliminate.

[0005] Therefore, there is an urgent need to design a cast aluminum door structure that does not require aluminum alloy edge clips and can avoid process seams and glue overflow, so as to simplify the process, reduce costs, and improve the integrity and simplicity of the door appearance. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a non-clamping embedded cast aluminum door structure.

[0007] This edgeless embedded cast aluminum door structure includes: a door core steel plate and an aluminum decorative panel; the outer surface of the door core steel plate is machined with grooves; the sidewalls of the grooves are molded edges, which are inclined to the outer surface of the door core steel plate; the inner surface of the aluminum decorative panel is lower than the middle of the inner surface of the aluminum decorative panel around its perimeter, and there is a slope between the perimeter and the middle of the inner surface of the aluminum decorative panel; the middle of the inner surface of the aluminum decorative panel is embedded in the groove, and the molded edges and the slopes are fitted together; the groove of the door core steel plate is filled with a structural adhesive layer.

[0008] Preferably, the door core steel plate is a cold-rolled steel plate with a thickness of 1.0-1.5mm; the height of the molding edge is 3-5mm, and the height of the molding edge matches the thickness of the aluminum decorative plate.

[0009] As a preferred option, the aluminum trim is made of cast aluminum with a thickness of 3-5mm.

[0010] Preferably, the structural adhesive layer is a weather-resistant silicone structural adhesive with a thickness of 0.5-1mm.

[0011] Preferably, the height of the outer surface of the aluminum trim panel above the outer surface of the groove edge of the door core steel panel is ≤1mm.

[0012] The beneficial effects of this utility model are:

[0013] 1) This utility model does not use aluminum alloy clip-on profiles. This clip-on-no-profile design reduces the profile customization and installation process, lowers material and labor costs, and simplifies the processing flow.

[0014] 2) This utility model forms a groove by molding the door core steel plate. After the aluminum decorative plate is embedded, it is flush with the door core steel plate, which completely eliminates the process seam on the side of the door leaf. The groove can also block the structural glue, avoiding glue overflow. No additional treatment of gaps and glue overflow is required, thus improving production efficiency.

[0015] 3) The outer surface of the door leaf of this utility model has no protruding edges or obvious gaps, has a strong sense of integrity, is simple and beautiful, and meets the needs of high-end decoration.

[0016] 4) This utility model adopts weather-resistant silicone structural adhesive combined with embedded positioning, and the connection strength between the aluminum decorative panel and the door core is high, making it suitable for outdoor and long-term use scenarios.

[0020] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0021] As one embodiment, a non-clamping embedded cast aluminum door structure is proposed, such as... Figure 1 and Figure 2 As shown, it includes: a steel core panel 1 and an aluminum decorative panel 4; as Figure 1 As shown, Figure 1The door panel body 6 includes a door core steel plate 1, a molded edge 2, a groove 3, an aluminum decorative panel 4, and a structural adhesive layer 5. The outer surface of the door core steel plate 1 is processed with a groove 3. Specifically, the door core steel plate 1 is molded into a groove 3 using a molding machine. The sidewall of the groove 3 is the molded edge 2, which is inclined to the outer surface of the door core steel plate 1. The inner surface of the aluminum decorative panel 4 is lower than the middle of the inner surface of the aluminum decorative panel 4 around its perimeter. There is a slope between the inner surface of the aluminum decorative panel 4 around its perimeter and the middle. The middle of the inner surface of the aluminum decorative panel 4 is embedded in the groove 3, and the molded edge 2 and the slope are in contact. The groove 3 of the door core steel plate 1 is filled with a structural adhesive layer 5. The outer surface of the aluminum decorative panel 4 is flush with or slightly higher than the outer surface of the molded edge 2.

[0022] like Figure 1 and Figure 2 As shown, the door core steel plate 1 is a cold-rolled steel plate with a thickness of 1.0-1.5mm; its four edges are molded inward to form a closed groove 3, the height of the molded edge 2 is 3-5mm, and the height of the molded edge 2 matches the thickness of the aluminum decorative plate 4; the outer surface of the aluminum decorative plate 4 covers the groove 3; the aluminum decorative plate 4 is made of cast aluminum with a thickness of 3-5mm, the inner surface of the aluminum decorative plate 4 is finely carved with a slope, and the outer surface of the aluminum decorative plate 4 is anodized to improve corrosion resistance and aesthetics;

[0023] The structural adhesive layer 5 is a weather-resistant silicone structural adhesive with a thickness of 0.5-1mm. This ensures bonding strength while avoiding cost waste or the risk of excess adhesive due to excessive thickness. The weather-resistant silicone structural adhesive is evenly applied to the bottom of the groove 3 of the door core steel plate. Due to the enclosure effect of the groove 3, the adhesive layer can be prevented from overflowing to the side of the door core steel plate 1. The aluminum decorative panel 4 is embedded in the groove 3 and pressed and fixed until the weather-resistant silicone structural adhesive cures. After curing, the outer surface of the aluminum decorative panel 4 is basically flush with the outer surface of the door core steel plate 1. The height of the outer surface of the aluminum decorative panel 4 above the outer surface of the groove 3 of the door core steel plate 1 is ≤1mm. The width of the aluminum decorative panel 4 matches the width of the door core steel plate 1. The door core steel plate 1 has no aluminum alloy edge clips, and there are no process seams or excess adhesive on the sides. Compared with the clip door structure, the processing steps are reduced by three steps: profile cutting, edge clip installation, and edge clip grinding, which reduces material costs and improves the simplicity of the appearance.
