Abstract
Description
Technical Field
[0001] This utility model relates to the field of building exterior wall panel technology, and in particular to non-load-bearing exterior cladding composite wall panels. Background Technology
[0002] Non-load-bearing composite wall panels refer to building materials used in the building's exterior envelope that do not bear the load of the main structure (such as the weight of floors and roofs), but only serve to separate indoor and outdoor spaces, protect the main structure, and provide physical properties such as thermal insulation, sound insulation, fire resistance, and waterproofing. They are an important component in modern architecture, particularly widely used in prefabricated and steel-structure buildings.
[0003] Traditional masonry walls (such as brick walls and block walls) are load-bearing or self-supporting structures, which have disadvantages such as long construction period, single function, and the need for additional insulation and decorative layers. Compared with traditional masonry walls, non-load-bearing exterior cladding composite wall panels have the advantages of being lightweight, prefabricated, functionally composite, and separate from the main structure, making them more suitable for the modern building's demand for high efficiency, energy saving, and aesthetics.
[0004] However, existing non-load-bearing composite wall panels suffer from drawbacks such as cumbersome production processes and long processing times. For example, the utility model patent with authorization announcement number CN207296168U discloses a prefabricated composite insulated exterior wall panel, including an outer leaf wall panel, an insulation layer, and an inner leaf wall panel, employing a "double-wall panel sandwich" structure. An insulation layer is sandwiched between two inner and outer wall panels, which are fixedly connected as a single unit by connectors. This structure is relatively complex. During the manufacturing process, steel bars need to be inserted from the outer leaf wall panel through the insulation layer into the inner leaf wall panel, resulting in a lengthy and cumbersome production process and significantly extending the molding cycle. Furthermore, after this non-load-bearing exterior wall panel is installed on the building structure, the presence of internal connectors creates thermal bridging, weakening its insulation performance and affecting the overall thermal insulation effect. Utility Model Content
[0005] In view of this, the technical problem to be solved by this utility model is to provide a non-load-bearing external cladding composite wall panel that can shorten the molding process, improve molding efficiency, and reduce molding difficulty; at the same time, it can eliminate the influence of thermal bridging and improve the thermal insulation effect.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0007] A non-load-bearing external cladding composite wall panel includes a substrate, wherein a receiving cavity is recessed on the outer wall of the substrate, and an adhesive bonding layer and a main insulation layer are sequentially arranged from the inside to the outside of the receiving cavity.
[0008] The outer wall of the main insulation layer is not higher than the outer wall of the substrate. An insulation reinforcement layer is provided on the outer wall of the substrate. The insulation reinforcement layer covers the main insulation layer. A mesh fabric layer is provided on the outside of the insulation reinforcement layer. An outer protective layer is provided on the outside of the mesh fabric layer.
[0009] Preferably, two insertion strips are protruding on one side wall of the substrate and arranged in the same direction along its length, and an insertion groove adapted to the insertion strips is recessed on the other side wall of the substrate.
[0010] Preferably, the inner wall of the substrate is provided with an upper fixing groove and a lower fixing groove, and bolt mounting holes are provided at the bottom of both the upper fixing groove and the lower fixing groove.

[0012] Preferably, the outer wall of the main insulation layer is lower than the outer wall of the substrate, and the insulation reinforcement layer extends into the receiving cavity and is connected to the side wall of the receiving cavity.
[0013] Preferably, the main insulation layer includes an insulation core board and a barrier bag. The barrier bag is wrapped around the outside of the insulation core board. The barrier bag includes two barrier films with the same structure and arranged opposite each other. The edges of the two barrier films are fixedly connected, and the two barrier films are tightly attached to the insulation core board and wrap it.
[0014] The barrier film includes an inner barrier layer disposed near the insulation core board and an outer barrier layer disposed on its outer side.
[0015] Preferably, the barrier bag is provided with an interface agent layer, which wraps around the connecting edge of the two barrier films.
[0016] Preferably, the insulation core board is a silicon dioxide board, the inner barrier layer is an aluminum foil layer, and the outer barrier layer is a glass fiber mesh layer.
[0017] Preferably, the thermal insulation reinforcement layer is a mortar layer of granulated polystyrene adhesive powder, and the outer protective layer is a plastering mortar layer.
[0018] After adopting the above technical solution, the beneficial effects of this utility model are:
[0019] Because the non-load-bearing exterior composite wall panel of this application includes a base plate, the outer wall of which is recessed with a receiving cavity, and an adhesive bonding layer and a main insulation layer are sequentially arranged from the inside to the outside of the receiving cavity; by setting a receiving cavity on the base plate, the main insulation layer is bonded to the bottom of the cavity through the adhesive bonding layer, the main insulation layer is first accommodated in the receiving cavity, and the main insulation layer is fixed by a base plate, preventing the main insulation layer from splitting off from the base plate and falling off. Moreover, it also eliminates the outer leaf wall panel in the traditional structure, simplifies the molding process, and improves molding efficiency; it also eliminates the process of the steel bars passing through the insulation layer, shortens the molding process, improves molding efficiency, and reduces molding difficulty; it also eliminates the thermal bridging effect caused by the presence of steel bars, and improves the thermal insulation effect.
[0020] The outer wall of the main insulation layer is not higher than the outer wall of the substrate. An insulation reinforcement layer is provided on the outer wall of the substrate, which covers the main insulation layer. The presence of the main insulation layer does not affect the overall flatness, making it convenient for construction on the outside of this application. Moreover, the insulation reinforcement layer can fix the main insulation layer. By covering the main insulation layer and the substrate, it fixes and protects the main insulation layer from the outside, preventing cracking between it and the substrate and improving the connection strength. At the same time, the insulation reinforcement layer can also play a role in assisting insulation, leveling and correction, and enhancing the bonding transition of the non-load-bearing external cladding composite wall panel of this application.

The mesh fabric layer is embedded in the outer protective layer, and it disperses stress and inhibits surface cracking through the mesh fabric. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0035] like Figures 1 to 6 As shown, this utility model includes a substrate 1, with a recessed cavity 11 on the outer wall of the substrate 1. An adhesive bonding layer 2 and a main insulation layer 3 are sequentially arranged from the inside to the outside within the cavity 11. By providing the cavity 11 on the substrate 1, and bonding the main insulation layer 3 to the bottom of the cavity via the adhesive bonding layer 2, the main insulation layer 3 is first accommodated within the cavity 11. The main insulation layer 3 is fixed using the substrate 1, preventing it from splitting and falling off. This also eliminates the need for an outer leaf wall panel in traditional structures, simplifying the molding process and improving molding efficiency. Furthermore, it eliminates the step of passing reinforcing bars through the insulation layer, shortening the molding process, improving molding efficiency, and reducing molding difficulty. It also eliminates the thermal bridging effect caused by the presence of reinforcing bars, improving the thermal insulation effect.
[0036] The outer wall of the main insulation layer 3 is not higher than the outer wall of the substrate 1. An insulation reinforcement layer 4 is provided on the outer wall of the substrate 1. The insulation reinforcement layer 4 covers the main insulation layer 3. The presence of the main insulation layer 3 does not affect the overall flatness of the insulation reinforcement layer 4, which facilitates construction on the outer side of this application. Moreover, the insulation reinforcement layer 4 can fix the main insulation layer 3. By covering the main insulation layer 3 and the substrate 1, it fixes and protects the main insulation layer 3 from the outside, preventing cracking between it and the substrate 1 and improving the connection strength. At the same time, the insulation reinforcement layer 4 can also play a role in assisting insulation, leveling and correction, and enhancing the bonding transition of the non-load-bearing external cladding composite wall panel of this application.
[0037] A mesh fabric layer 6 is provided on the outer side of the thermal insulation reinforcement layer 4, and an outer protective layer 5 is provided on the outer side of the mesh fabric layer 6. The mesh fabric layer 6 is embedded in the outer protective layer 5, and the mesh fabric disperses stress and inhibits surface cracking. Preferably, the mesh fabric layer 6 is a glass fiber mesh fabric layer.
[0038] In this application, two insertion strips 12 protruding from one side wall of substrate 1 and arranged in the same direction along its length are provided, and an insertion groove 13 adapted to the insertion strips 12 is recessed on the other side wall of substrate 1. During construction, the insertion strip 12 on one of the two adjacent substrates 1 is inserted into the insertion groove 13 on the adjacent substrate 1 to connect the two substrates 1 together.
[0039] The inner wall of the substrate 1 is provided with an upper fixing groove 14 and a lower fixing groove 15, and bolt mounting holes 16 are opened at the bottom of both the upper fixing groove 14 and the lower fixing groove 15. The upper fixing groove 14 and the lower fixing groove 15 are provided for connection with the connector by bolts. During construction, the bolts pass through the connector and extend into the bolt mounting holes 16, and another bolt fixes the connector to the building structure, thereby fixing the substrate 1 through the connector. Preferably, the substrate 1 is a precast cement slab or a lightweight concrete slab, and the adhesive bonding layer 2 is an adhesive mortar layer.
[0040] In this application, the outer wall of the main insulation layer 3 is lower than the outer wall of the substrate 1, and the insulation reinforcement layer 4 extends into the receiving cavity 11 and is connected to the side wall of the receiving cavity 11.
[0041] The outer wall of the main insulation layer 3 is lower than the outer wall of the substrate 1, so it will not affect the flatness of the substrate 1; the insulation reinforcement layer 4 extends into the receiving cavity 11 and is connected to its side wall, which can enhance the fixing effect of the insulation reinforcement layer 4 on the main insulation layer 3 and the connection strength with the receiving cavity 11, and prevent cracking at the connection.
[0042] The main insulation layer 3 is a vacuum insulation board. The main insulation layer 3 includes an insulation core board 31 and a barrier bag 32. The barrier bag 32 is wrapped around the outside of the insulation core board 31. The barrier bag 32 includes two barrier films 33 with the same structure and arranged opposite each other. The edges of the two barrier films 33 are fixedly connected. The two barrier films 33 are tightly attached to the insulation core board 31 and wrap it. The barrier film 33 includes an inner barrier layer 331 disposed near the insulation core board 31 and an outer barrier layer 332 disposed on its outside.
[0043] The insulation core board 31 is a silica board, the inner barrier layer 331 is an aluminum foil layer, and the outer barrier layer 332 is a fiberglass mesh layer. Silica board has the advantages of low density, high specific surface area, and high porosity, making it a highly efficient thermal insulation material. The aluminum foil layer has excellent flexibility and moisture resistance, allowing it to tightly adhere to the insulation core board 31, effectively blocking external moisture intrusion and preventing water vapor from penetrating the insulation core board 31, thus avoiding the impact of moisture on the thermal insulation performance of the silica board. Simultaneously, the aluminum foil has high reflectivity to heat radiation, reflecting most of the heat back, further enhancing the overall thermal insulation effect of the structure.
[0044] Fiberglass mesh has good wear resistance, corrosion resistance and low temperature toughness. Using it to encapsulate the insulation core board 31 can improve the service life of the main insulation layer 3. Furthermore, by vacuum hot-pressing the fiberglass mesh, even if there is damage and air leakage, the entire main insulation layer 3 will not expand and bulge, thus avoiding the peeling off of the building wall decoration layer.
[0045] An interface agent layer 34 is provided on the barrier bag 32, which wraps around the connecting edge of the two barrier films 33. The main function of the interface agent layer 34 wrapping around the connecting edge of the two barrier films 33 of the barrier bag 32 is to enhance the adhesion between the edge of the barrier bag 32 and the surrounding structure, seal the edge gaps to prevent water vapor from seeping in, improve the overall sealing and stability of the main insulation layer 3, and avoid the decrease in insulation performance or structural failure due to poor edge adhesion.
[0046] In this application, the insulation reinforcement layer 4 is a layer of mortar made of adhesive-coated polystyrene particles. This mortar is a thermal insulation material made primarily from adhesive powder (a high-molecular polymer) and polystyrene particles (lightweight particles obtained from crushed waste polystyrene boards), mixed with cement, sand, and other materials. It combines thermal insulation, bonding, crack resistance, and leveling functions. It has a low thermal conductivity, can be mixed on-site during construction, and is suitable for exterior and interior wall insulation, roof insulation, and other applications. It enhances building energy efficiency and is environmentally friendly (utilizing waste polystyrene boards) with a simple manufacturing process, making it a commonly used composite material in building insulation systems.
[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
