[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] like Figure 1-7 As shown, a composite insulation and decorative panel for building exterior walls is provided, including: an insulation layer spliced ​​from multiple composite decorative panels 1 and fastening components 2 disposed at the gaps in the insulation layer, wherein the gaps in the insulation layer refer to the space between adjacent composite decorative panels 1.

[0031] Composite decorative panels 1 are fixed to the exterior wall of the building in a matrix arrangement to form a continuous insulation layer. A fastening component 2 is provided at the joint of every four composite decorative panels 1 to reinforce the insulation layer and enable rapid positioning and installation, aiming to improve construction efficiency.

[0032] The composite decorative panel 1 includes: the panel body 3 and the outer rectangular frame 4.

[0033] like Figure 3 As shown, the main body 3 is the main part of the composite decorative panel 1. It consists of multiple layers, including: a base material layer 301, an insulation material layer 302, and a decorative surface layer 303. The insulation material layer 302 is disposed on the front side of the base material layer 301, and the decorative surface layer 303 is disposed on the front side of the insulation material layer 302. The base material layer 301 is fixed to the exterior wall with an adhesive.

[0034] The base material layer 301 is the foundation layer of the board body 3. It is usually made of durable inorganic materials, such as fiber cement board, gypsum board or ceramic tile. The base material layer 301 needs to have sufficient strength and durability to support the weight of the entire board and various external loads.

[0035] The insulation material layer 302 is the core layer of the main body 3, used to provide thermal insulation performance. Insulation material layer 302 is one or more of polystyrene foam board, extruded polystyrene foam board, rock wool board, and glass wool board. EPS boards have low density, reducing the building's self-weight, and have high thermal insulation performance, effectively reducing heat transfer. XPS boards have better thermal insulation performance than EPS boards, and also have better compressive strength, able to withstand greater external pressure. Rock wool boards have the advantage of excellent fire resistance, meeting building fire protection requirements. Glass wool boards have good sound absorption properties, reducing noise.

[0036] Decorative Surface Layer 303 is the outer layer of the composite decorative panel, used to provide an aesthetically pleasing appearance. Decorative Surface Layer 303 can be made of artificial stone, real stone paint, fluorocarbon paint, or metal. The choice of materials such as artificial stone, real stone paint, fluorocarbon paint, or metal for Decorative Surface Layer 303 can be based on the building's design style and functional requirements. These materials not only provide an attractive appearance but also meet requirements for durability, weather resistance, stain resistance, and environmental friendliness, making the building's exterior walls more appealing.

[0037] The outer rectangular frame 4 covers the side edges of the main panel 3. That is, the outer rectangular frame 4 refers to the frame structure surrounding the side edges of the main panel 3, which fits tightly against the main panel 3. It is usually pre-manufactured with fixed dimensions and shape, giving the composite decorative panel 1 high strength. The rigid structure of the frame can distribute external pressure and stress, reducing the risk of deformation and damage to the main panel 3. At the same time, the outer rectangular frame 4, used in conjunction with the fastening components 2, reduces construction difficulty and improves construction efficiency.

[0038] Positioning pieces 401 are provided at the four corners of the front and rear sides of the outer rectangular frame 4, that is, each composite decorative panel 1 has a total of eight positioning pieces 401. The positioning pieces 401 have clamping slots 403 for use with fastening components 2.

[0039] An elongated hollow groove 402 is opened on the outer rectangular frame 4, so that part of the side of the main body 3 of the board is exposed. This reduces the overall weight of the composite decorative board 1 and allows the adhesive to come into contact with the main body 3 when filling the gaps with grout or special sealant, thereby increasing the bonding strength.

[0040] The fastening assembly 2 includes: a mounting base 5 and a locking cover 6.

[0041] Mounting base 5 is installed on the exterior wall to fix the composite decorative panel 1 to the exterior wall. It is usually made of metal or other sturdy materials and has a certain strength and durability. A countersunk hole is formed in the center of the mounting base 5. The countersunk hole is a hole to accommodate bolts, anchors, and other connecting parts. It is usually designed to be slightly larger than the diameter of the connecting parts to facilitate installation and removal. Bolts or anchors pass through the countersunk hole on the mounting base 5 and are further secured inside the wall. This can be done by tightening the bolts or using specific anchor installation tools.

[0042] The locking cover 6 is connected to the mounting base 5 to hold the corner portion of the composite decorative panel 1 between the locking cover 6 and the mounting base 5. The locking cover 6 is used to fix the corner portion of the composite decorative panel 1, and its function is to hold the corner portion of the composite decorative panel between the locking cover 6 and the mounting base 5. This holding action helps to ensure that the composite decorative panel at the corner will not shift or warp due to temperature changes, wind loads or other external forces.

[0043] After the locking cover 6 is connected to the mounting base 5, the corner part of the mounting base 5 is embedded in the mounting groove 403 opened on the positioning piece at the four rear corners of the outer rectangular frame 4; the corner part of the locking cover 6 is embedded in the mounting groove 403 opened on the positioning piece at the four front corners of the outer rectangular frame 4.

[0044] The installation process is as follows:

[0045] The first step is to clean the wall. Use tools such as a hammer and scraper to remove loose materials from the wall, wash the wall to remove dust, grease and dirt, use sandpaper to smooth out cracks and holes, and fill cracks and holes with repair materials (such as putty, plaster, etc.) as needed.

[0046] The second step is to mark the lines on the wall. Use a level and plumb line to determine the horizontal and vertical lines of the wall as reference lines. Based on the design dimensions of the composite decorative panel 1 and the actual conditions of the wall, determine the installation position of the composite decorative panel 1, thereby determining the position of the installation base 5.

[0047] The third step is to secure the mounting base 5. At the marked location, use bolts or other connecting structures to fix the mounting base 5 to the exterior wall, such as... Figure 5 As shown.

[0048] Step 4: Fix the composite decorative panel 1. Apply a layer of primer to the wall to form a base layer, enhancing the adhesion between the composite decorative panel 1 and the wall. Apply a layer of adhesive evenly to the base layer, generally 3-5mm thick, ensuring the adhesive covers the entire surface. Align the composite decorative panel 1 in position and press gently to ensure a tight bond between the panel and the base layer. Figure 6 As shown.

[0049] In this step, since the mounting base 5 has been pre-fixed, when pasting the composite decorative panel 1, simply move the composite decorative panel 1 slightly so that the four mounting slots 403 on the back of the composite decorative panel 1 fit precisely into the corners of the mounting base 5 without any lifting. This indicates that the composite decorative panel 1 is in the correct position, and then press the panel down. In the above process, the composite decorative panel 1 plays a positioning role, making it easier to find the correct position and reducing the difficulty of installation. Moreover, after installation, using the locking cover 6 to press down the composite decorative panel 1 can also ensure the stability of the cavity.

[0050] Step 5: Secure the locking cover 6. One locking cover 6 is fixed to each mounting base 5. The corner portions of the locking cover 6 are fitted into the slots 403 on the positioning plates at the four front corners of the outer rectangular frame 4, ensuring a smooth surface for the insulation layer. Figure 7 As shown.

[0051] like Figure 4 As shown, a slot 501 is provided at the opening of the countersunk hole to accommodate the insertion rod 601; the locking cover 6 is provided with an insertion rod 601 that is adapted to the slot 501 for easy insertion. A limiting platform 502 is provided on the wall of the slot 501 to provide a locking function, and a locking protrusion 602 is provided at the end of the insertion rod 601 to prevent the insertion rod 601 from coming out.

[0052] When the locking cover 6 is installed, the insertion groove 501 deforms as the insertion rod 601 is inserted until the locking protrusion 602 passes the limiting platform 502. After the locking protrusion 602 passes the limiting platform 502, the insertion groove 501 returns to its original shape and achieves the limiting function. This means that the insertion rod 601 cannot come out of the insertion groove 501, thus ensuring a firm connection between the locking cover 6 and the mounting base 5.

[0053] The above structural design allows for quick connection between the locking cover 6 and the mounting base 5 through a simple insertion operation, improving installation efficiency. Furthermore, the engagement between the snap-fit ​​protrusion 602 and the limiting platform 502 ensures a secure connection and prevents loosening or detachment.

[0054] Preferably, the top of the limiting platform 502 and the bottom of the snap-fit ​​protrusion 602 are provided with inclined surfaces so that the insertion rod 601 can be smoothly inserted into the insertion slot 501 when the locking cover 6 is installed.

[0055] Step 6: Fill the gaps in the insulation boards. Insulation adhesive is a special adhesive used to bond insulation materials, and it can also be used to fill gaps in insulation boards. Insulation adhesive has good adhesion and elasticity, can adapt to temperature changes, and prevents gaps from cracking. When filling the gaps with insulation adhesive, first fill the adhesive into the gaps, then use a tool to press it firmly, making it flush with the surface of the insulation board.

[0056] The fastening assembly 2 also includes an extension reinforcing rod 7; one end of the extension reinforcing rod 7 is connected to the fastening cover 6, and the other end of the extension reinforcing rod 7 extends into the gap between two adjacent composite decorative panels 1. This design helps to ensure the stability of the thermal insulation adhesive and provides additional support and fixation.

[0057] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
