DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail with reference to the accompanying drawings.

[0028] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0030] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection, or communication; it can be directly connected, or indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0031] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. In the description of the specification, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0032] Example 1:

[0033] AsFigures 1-4 As shown, before construction, the integrated exterior wall panel first requires the sequential bonding of its internal functional layers: the mounting base plate 1 is made of thick aluminum-zinc coated steel plate, and the surface is phosphated to improve adhesion. Then, M12 chemical anchors are pre-embedded to facilitate fixation to the building concrete wall during subsequent building construction; the adhesive layer 2 is evenly coated on the surface of the mounting base plate, left to stand for 10 minutes until initial setting, and then bonded to the insulation base plate 3 by a roller press. The joint between the insulation base plate 3 and the adhesive layer 2 is sealed with polyurethane foam; the buffer layer 101 adopts an elastic rubber structure, and a wavy structure is set at the bottom, thereby forming a wavy expansion joint 201 set above the insulation base plate 3.

[0034] Furthermore, the surface of the decorative metal panel is treated with fluorocarbon spraying and embossed with a granite-like texture. Dovetail-style interlocking parts 6 are machined on all four sides of the panel to facilitate assembly and fixing during construction.

[0035] Furthermore, the waterproof layer 4 uses TPO polymer waterproof membrane, and the joints are treated with hot air welding. The edges are reinforced with butyl tape, which effectively improves the sealing performance of the waterproof layer 4. At the same time, it can extend the service life of the integrated exterior wall panel and reduce the overall maintenance cost in subsequent use.

[0036] Example 2:

[0037] like Figures 1-4 As shown, the mounting base 1 is fixed to the building wall by embedded parts, and the insulation base 3 is pasted after the surface is coated with an adhesive layer 2. The insulation base is made of 50mm thick polyurethane foam board, on which a polymer waterproof membrane is laid as a waterproof layer 4. An 8mm thick rubber buffer layer 101 is set on the outside of the waterproof layer 4, and a corrugated expansion joint 201 is opened in the buffer layer 101. The decorative metal plate 5 is made of aluminum-magnesium alloy, and the edges are processed with dovetail-type snap-fit ​​parts 6. It interlocks with the adjacent plate through the snap-fit ​​parts 6 and is locked to the mounting base 1 by stainless steel fixing bolts 7 passing through the mounting bolt holes 301.

[0038] Furthermore, the buffer layer 101 is a composite layer of shape memory alloy and elastomer, which automatically deforms when the temperature rises, thereby changing the width of the expansion joint 201 below; the expansion joint 201 located below can open and close with temperature changes to adjust the ventilation of the insulation layer, thereby playing the role of internal moisture protection.

[0039] Example 3:

[0040] To address the challenges of low-temperature construction environments, the following improvements were implemented:

[0041] The thickness of the insulation substrate 3 is increased, and XPS extruded board is added as an auxiliary insulation layer;

[0042] The buffer layer 101 is made of low-temperature-resistant silicone rubber, and the expansion joint 201 arranged at the lower position has a width of 5mm;

[0043] The fixing bolt 7 is pre-coated with low-temperature lubricating grease, and the assembly torque is reduced, so as to avoid cold brittle fracture in the assembly process and improve the construction cost.

[0044] The construction steps of the integrated external wall panel are as follows:

[0045] During construction, first, the functional layers are sequentially compounded, then the mounting base plate 1 is fixed to the wall surface, and the decorative metal plate 5 is fixed by clamping and bolting, so as to realize the warm renovation construction of the old building external wall. The structure effectively disperses stress and avoids deformation of the panel caused by temperature change, while ensuring the sealing performance of the joint.

[0046] As can be seen from the above embodiments, the utility model realizes the deep integration of decoration, heat preservation and waterproof function through accurate interlayer matching and process control. The combination design of the elastic buffer layer and the wave-shaped expansion joint can absorb the linear thermal deformation within the range; the dovetail clamping and hidden bolt fixing take into account the installation efficiency and the appearance integrity. The variant schemes of different embodiments further expand the application scenarios of the product and meet the diversified engineering needs.

[0047] The places not mentioned in the application can be realized by using or referring to the existing technology.

[0048] Each embodiment in the specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.

[0049] The above only describes the embodiments of the application and does not limit the application. Those skilled in the art can make various modifications and changes to the application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the application shall be included in the scope of the claims of the application.
