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 wall panel structure. Background Technology
[0002] Non-load-bearing exterior wall panels refer to building materials that do not bear the load of the main structure (such as the weight of floors and roofs) in the building's exterior envelope. Their function is solely to separate interior and exterior 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 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 exterior wall panel structures 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 using connectors. This structure is relatively complex. During the manufacturing process, reinforcing bars need to be inserted from the outer leaf wall panel through the insulation layer into the inner leaf wall panel, resulting in lengthy and cumbersome production processes and significantly extending the molding cycle. Furthermore, after installing this non-load-bearing exterior wall panel 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 wall panel structure 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] The non-load-bearing external wall panel structure includes a base plate, and an adhesive bonding layer, a main insulation layer and an insulation reinforcement layer are sequentially arranged on the outer wall of the base plate from the inside to the outside.
[0008] The adhesive bonding layer covers the surface of the substrate and the sidewalls of both are flush;
[0009] The sidewall of the main insulation layer is located inside the sidewall of the substrate, and there is a gap between the two sidewalls;
[0010] The thermal insulation reinforcement layer covers the surface and sidewalls of the main thermal insulation layer. The sidewalls of the thermal insulation reinforcement layer are flush with the sidewalls of the substrate. The thermal insulation reinforcement layer and the adhesive bonding layer cooperate to wrap the main thermal insulation layer.
[0011] 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.
[0012] 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.
[0013] Preferably, the substrate is a precast cement board or a lightweight concrete board, and the adhesive bonding layer is an adhesive mortar layer.
[0014] 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.
[0015] The barrier film includes an inner barrier layer disposed near the insulation core board and an outer barrier layer disposed on its outer side.
[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 barrier bag is provided with an interface agent layer, which wraps around the connecting edge of the two barrier films.
[0018] Preferably, the thermal insulation reinforcement layer is a mortar layer of granulated polystyrene adhesive powder.
[0019] Preferably, an outer protective layer is provided on the outside of the thermal insulation reinforcement layer, and a mesh fabric layer is provided inside the outer protective layer.
[0020] Preferably, the outer protective layer is a plastering mortar layer.
[0021] After adopting the above technical solution, the beneficial effects of this utility model are:
[0022] Because the non-load-bearing exterior wall panel structure of this application includes a substrate, and an adhesive bonding layer, a main insulation layer and an insulation reinforcement layer are sequentially arranged on the outer wall of the substrate from the inside to the outside; wherein, the adhesive bonding layer covers the surface of the substrate and the side walls of the two are flush, the side wall of the main insulation layer is located inside the side wall of the substrate and there is a gap between the side walls of the two, the main insulation layer is fixed to the substrate through the adhesive bonding layer, the adhesive bonding layer transmits shear force to prevent the main insulation layer from falling off, the main insulation layer is located in the middle of the substrate and plays the main insulation function, which greatly reduces the thermal conductivity of the wall and meets the building energy-saving design requirements.
[0023] The thermal insulation reinforcement layer covers the surface and sidewalls of the main thermal insulation layer. The sidewalls of the thermal insulation reinforcement layer are flush with the sidewalls of the substrate. The thermal insulation reinforcement layer and the adhesive bonding layer work together to wrap the main thermal insulation layer. After molding, the thermal insulation reinforcement layer wraps around the outside and all sides of the main thermal insulation layer, which can fix the main thermal insulation layer. It is connected to the substrate through the adhesive bonding layer, fixing the main thermal insulation layer between the two, preventing cracking between it and the substrate, and improving the connection strength. At the same time, the thermal insulation reinforcement layer can also play a role in assisting thermal insulation, leveling and correction, and enhancing the bonding transition of the non-load-bearing external wall panel structure of this application.
[0024] Compared to traditional wall panel structures, this application eliminates the outer leaf wall panel found in traditional structures on the outside of the main insulation layer. Instead, a reinforcing insulation layer replaces and wraps around the main insulation layer. This reduces the weight of the outer side of the main insulation layer, lowers the shear force between it and the substrate, and prevents detachment. It also enhances the overall insulation effect and improves the insulation capacity. Furthermore, the process of passing the reinforcing steel through the insulation layer is eliminated, shortening the molding process, improving molding efficiency, and reducing molding difficulty. It also eliminates the thermal bridging effect caused by the presence of the reinforcing steel, further improving the thermal insulation performance. Attached Figure Description

[0036] 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.
[0037] like Figures 1 to 5 As shown, this utility model includes a substrate 1. From the inside out, an adhesive bonding layer 2, a main insulation layer 3, and an insulation reinforcement layer 4 are sequentially disposed on the outer wall of the substrate 1. The adhesive bonding layer 2 covers the surface of the substrate 1, and the sidewalls of both are flush. The sidewall of the main insulation layer 3 is located inside the sidewall of the substrate 1, and there is a gap between the two sidewalls. The main insulation layer 3 is fixed to the substrate 1 by the adhesive bonding layer 2, which transmits shear force to prevent the main insulation layer 3 from falling off. The main insulation layer 3 is located in the middle of the substrate 1 and performs the main insulation function, significantly reducing the thermal conductivity of the wall and meeting the requirements of building energy-saving design.
[0038] The thermal insulation reinforcement layer 4 covers the surface and sidewalls of the main thermal insulation layer 3. The sidewalls of the thermal insulation reinforcement layer 4 are flush with the sidewalls of the substrate 1. The thermal insulation reinforcement layer 4 and the adhesive bonding layer 2 work together to wrap around the main thermal insulation layer 3. After molding, the thermal insulation reinforcement layer 4 wraps around the outside and all sides of the main thermal insulation layer 3, which can fix the main thermal insulation layer 3. It is connected to the substrate 1 through the adhesive bonding layer 2, fixing the main thermal insulation layer 3 between the two, preventing cracking between it and the substrate 1, and improving the connection strength. At the same time, the thermal insulation reinforcement layer 4 can also play a role in assisting thermal insulation, leveling and correction, and enhancing the bonding transition of the non-load-bearing external wall panel structure of this application.
[0039] Compared to traditional wall panel structures, this application eliminates the outer leaf wall panel found in traditional structures on the outside of the main insulation layer 3, replacing and wrapping the main insulation layer 3 with an insulation reinforcement layer 4. This reduces the weight of the outer side of the main insulation layer 3, lowers the shear force between it and the substrate 1, and prevents detachment; it also enhances the overall insulation effect and improves the insulation capacity. Furthermore, the process of passing the reinforcing steel bars through the insulation layer is eliminated, shortening the molding process, improving molding efficiency, and reducing molding difficulty; it also eliminates the thermal bridging effect caused by the presence of reinforcing steel bars, thus improving the thermal insulation effect.
[0040] like Figure 1 , Figure 5 As shown, two insertion strips 11 protruding from one side wall of substrate 1 and arranged in the same direction along its length are provided, and an insertion groove 12 adapted to the insertion strips 11 is recessed on the other side wall of substrate 1. During construction, the insertion strip 11 on one substrate 1 is inserted into the insertion groove 12 on the adjacent substrate 1 to connect the two substrates 1 together.
[0041] The inner wall of the substrate 1 is provided with an upper fixing groove 13 and a lower fixing groove 14, and bolt mounting holes 15 are opened at the bottom of both the upper fixing groove 13 and the lower fixing groove 14. The upper fixing groove 13 and the lower fixing groove 14 are provided for connection with the connector by bolts. During construction, the bolts pass through the connector and extend into the bolt mounting holes 15, 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 board or a lightweight concrete board, and the adhesive bonding layer 2 is an adhesive mortar layer.
[0042] In this application, 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] Preferably, 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] An outer protective layer 6 is provided on the outside of the thermal insulation reinforcement layer 4, and a mesh fabric layer 5 is provided inside the outer protective layer 6. The outer protective layer 6 is a plastering mortar layer. The mesh fabric layer 5 is an alkali-resistant fiberglass mesh fabric, which is embedded in the plastering mortar layer. The alkali-resistant fiberglass mesh fabric disperses stress and inhibits surface cracking.
[0048] 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.
