Description

Technical Field

[0001] This utility model relates to the field of aluminum composite panels for exterior walls, and more specifically, to a new type of aluminum composite panel for exterior walls. Background Technology

[0002] The new type of aluminum composite panel for exterior walls is a composite decorative material that combines aluminum alloy and plastic core material. In recent years, through structural optimization, material improvement and process innovation, the performance of traditional aluminum composite panels has been significantly improved, especially in terms of installation efficiency, compression resistance, weather resistance and environmental protection.

[0003] When existing aluminum composite panels for exterior walls are used, they are prone to deformation and delamination due to external impacts or environmental factors.

[0004] Therefore, there is an urgent need for a method that can improve the performance of aluminum composite panels for exterior walls. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of aluminum composite panel for exterior walls, so as to solve the technical defects existing in the above-mentioned background technology.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A novel aluminum composite panel for exterior walls, comprising an upper aluminum panel, a middle structure, and a lower aluminum panel, wherein the upper aluminum panel and the lower aluminum panel have the same structure, characterized in that: a surface coating and a peelable protective film are sequentially provided on the upper surface of the upper aluminum panel;

[0008] The middle layer structure includes a core polyethylene layer and an elastic connecting mechanism embedded therein;

[0009] The elastic connection mechanism includes: a lower folding plate, the upper part of which is connected to the upper aluminum plate, and the lower part which extends into the polyethylene layer to form a lateral extension;

[0010] The upper folding plate is connected to the lower aluminum plate at its lower part, and extends into the polyethylene layer at its upper part to form a lateral extension that overlaps with the lateral extension of the lower folding plate.

[0011] The upper and lower folding plates have mutually cooperating limiting grooves and limiting strips on their opposite surfaces, and the overlapping surfaces have concave frames that are connected to the limiting spring strips.

[0012] Lateral displacement is restricted by the cooperation of the limiting groove and the limiting strip, while the concave frame and the limiting spring strip provide longitudinal elastic support, ensuring that the upper and lower aluminum plates maintain structural integrity when subjected to external forces (such as wind pressure and vibration).

[0013] With the polyethylene layer as the axis of symmetry, an upper aluminum plate and a lower aluminum plate are respectively provided on its upper and lower surfaces. With the polyethylene layer as the axis of symmetry, the upper and lower aluminum plates are symmetrically distributed to balance bidirectional stress and avoid stress concentration on one side.

[0014] As a further embodiment of this invention, the elastic connecting mechanism is evenly distributed in a plurality of parts along the length of the polyethylene layer, which disperses stress and improves overall strength.

[0015] As a further embodiment of this utility model, the folding plate is L-shaped, and the upper folding plate is inverted L-shaped. The two form a cross-locking structure within the polyethylene layer. The L-shaped lower folding plate and the inverted L-shaped upper folding plate form a cross-locking structure. Through the interlocking of their geometric shapes, the upper and lower aluminum plates are prevented from sliding or separating relative to each other.

[0016] As a further embodiment of this utility model, the limiting spring strip is made of shape memory alloy material. Shape memory alloy has better fatigue resistance, avoids the decrease of elasticity after long-term use, and ensures that the connecting mechanism is always tight.

[0017] As a further embodiment of this utility model, the surface coating is a fluorocarbon coating with a thickness of 20-50μm, and the protective film is a PE release film.

[0018] Beneficial effects of utility models

[0019] Compared with traditional aluminum composite panels for exterior walls, this utility model has the following advantages:

[0020] This utility model solves the technical pain points of traditional aluminum composite panels, such as easy deformation, delamination, and poor weather resistance, through the innovative combination of a cross-locking elastic connection mechanism, a limiting spring strip, and a limiting groove and limiting strip. It also features high strength, high durability, lightweight, and convenient construction, making it suitable for high-end exterior wall decoration, curtain wall projects, and buildings in harsh environments. It has significant technical advantages and market competitiveness. Attached Figure Description

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-3 As shown, this utility model provides a new technical solution for aluminum composite panels for exterior walls:

[0029] As shown in the figure, a new type of aluminum composite panel for exterior walls has a structure including an upper aluminum panel 1, a middle structure and a lower aluminum panel 6. The upper aluminum panel 1 and the lower aluminum panel 6 have the same structure. The feature is that the upper surface of the upper aluminum panel 1 is provided with a surface coating 2 and a peelable protective film 3 in sequence.

[0030] The middle layer structure includes a core polyethylene layer 4 and an elastic connecting mechanism 5 embedded therein;

[0031] The elastic connection mechanism 5 includes: a lower folding plate 51, the upper part of which is connected to the upper aluminum plate 1, and the lower part which extends into the polyethylene layer 4 to form a transverse extension.

[0032] The upper folding plate 52 is connected to the lower aluminum plate 6 at its lower part, and extends into the polyethylene layer 4 at its upper part to form a lateral extension that overlaps with the lateral extension of the lower folding plate 51.

[0033] The upper folding plate 52 and the lower folding plate 51 have mutually cooperating limiting grooves 5a and limiting strips 5b on their opposite surfaces. The overlapping surfaces have an inner recessed frame 5d, which is connected to the limiting spring strip 5c.

[0034] Lateral displacement is restricted by the cooperation of the limiting groove 5a and the limiting strip 5b, while the concave frame 5d and the limiting spring strip 5c provide longitudinal elastic support, ensuring that the upper and lower aluminum plates maintain structural integrity when subjected to external forces (such as wind pressure and vibration).

[0035] With the polyethylene layer 4 as the axis of symmetry, an upper aluminum plate 1 and a lower aluminum plate 6 are respectively provided on its upper and lower surfaces. With the polyethylene layer as the axis of symmetry, the upper and lower aluminum plates are symmetrically distributed to balance bidirectional stress and avoid stress concentration on one side.

[0036] The elastic connecting mechanism 5 is evenly distributed in multiples along the length of the polyethylene layer 4, which disperses stress and improves the overall strength.

[0037] The lower fold 51 is L-shaped, and the upper fold 52 is inverted L-shaped. The two form a cross-locking structure within the polyethylene layer 4. The L-shaped lower fold 51 and the inverted L-shaped upper fold 52 form a cross-locking structure. Through the interlocking of their geometric shapes, the upper and lower aluminum plates are prevented from sliding or separating relative to each other.

[0038] The 5c limit spring bar is made of shape memory alloy material. Shape memory alloy has better fatigue resistance, avoids the decrease of elasticity after long-term use, and ensures that the connection mechanism is always tight.

[0039] The topcoat 2 is a fluorocarbon coating with a thickness of 20-50μm, and the protective film 3 is a PE release film.

[0040] The specific implementation principle is as follows: The L-shaped lower folding plate 51 and the inverted L-shaped upper folding plate 52 form a cross interlock, which prevents the upper and lower aluminum plates from sliding or separating relative to each other through the interlocking of their geometric shapes. The limiting spring strip 5c is made of shape memory alloy material and restricts lateral displacement through the cooperation of the limiting groove 5a and the limiting strip 5b. The concave frame 5d and the limiting spring strip 5c provide longitudinal elastic support to ensure that the upper and lower aluminum plates maintain structural integrity when subjected to external forces (such as wind pressure and vibration).

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
