[0002] With the increase in residential, apartment, office, educational, and hospital buildings in my country, the requirements for sound insulation and thermal insulation are also becoming increasingly stringent. Ordinary wall materials cannot effectively isolate the sound insulation problems caused by vibrations. Good sound insulation and thermal insulation environments have become one of the important characteristics of green buildings. As a result, various types of exterior wall panels are constantly being introduced and widely used in the construction industry.

[0003] Currently, existing exterior wall panels are not strong enough and are prone to falling off after being installed on the wall. They also have problems with poor sound insulation and heat preservation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a wall panel with a biomimetic interlocking structure. The layer structure specifically includes an inner layer panel, an aerogel coating, and a surface panel, offering strong sound and heat insulation. Simultaneously, the outer side of the inner layer panel has multiple parallel protruding ribs arranged at an angle; the inner side of the surface panel has multiple parallel grooves adapted to the protruding ribs, also arranged at an angle. When in use, along the direction of the transverse ribs, the wall panel resists in-plane loads through the mechanical interlocking force of the protruding ribs, the frictional force of the overlapping interface, and the adhesive force of the aerogel coating; along the direction of the connecting ribs, the wall panel resists out-of-plane loads through the mechanical interlocking force of the protruding ribs and the frictional force of the overlapping interface.

Correspondingly, the two sides of the groove of the surface panel are concave or convex, thereby forming an inclined surface overlapping state on the inner side of the surface panel. Thus, the inner layer plate and the surface panel form an inclined surface overlapping and interlocking state. Furthermore, the mutual embedding between the various structural layers is achieved through the arrangement of the convex rib on the inner layer plate and the groove on the surface panel.

[0027] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Figure 1 This invention provides a schematic diagram of a wall panel structure with a biomimetic interlocking structure, as shown in the embodiment of the present invention. Figure 2 An exploded view of a wall panel with a biomimetic interlocking structure is provided for an embodiment of this utility model, as shown in the figure. Figure 1 and Figure 2As shown in the figure, the wall panel with a biomimetic interlocking structure provided in this embodiment of the utility model includes an inner layer plate 1, an aerogel coating 2 and a surface panel 3 from the inside to the outside. The layer structure of the wall panel will be described in detail below.

[0029] The inner layer 1 has multiple parallel protruding ribs 121 on its outer side. The two sides of each rib 121 are beveled. The ribs adopt a joint-like skeletal design, providing in-plane and out-of-plane constraints while minimizing stress concentration at the edges, thus maximizing their strength. It is understood that a boundary line 122 is formed between two adjacent ribs 121, with the two bevels symmetrical along the boundary line 122. The multiple ribs 121 combine to form an undulating, overlapping surface on the outer side of the inner layer 1, which interlocks with the inner side of the facing panel 3, providing additional resistance and increasing the wall's strength. It should be noted that a mold is used during the casting of the inner layer 1. The mold is pre-set with the final shape of the cast inner layer 1, meaning it also has the aforementioned protruding ribs 121 and the beveled surfaces on both sides. Preferably, the thickness of the inner layer 1 is 5 to 500 mm and the strength is not less than 50 MPa, thereby ensuring that the wall panel has good sound insulation and strength.

[0030] In some preferred embodiments, the inner layer 1 may specifically include a skeleton 11 and a panel 12, wherein the panel 12 is a panel with a skeleton 11.

[0031] Specifically, the skeleton 11 here is a load-bearing component. The skeleton includes, but is not limited to, various types of reinforcement such as ordinary strength, high strength, and FRP. Specifically, it includes multiple horizontal bars 111, vertical bars 112, reinforcing bars 113, and connecting bars 114. Horizontal bars 111 refer to horizontally placed steel bars, and vertical bars 112 refer to vertically placed steel bars. Multiple horizontal bars 111 are arranged in parallel, and multiple vertical bars 112 are arranged in parallel and perpendicular to the horizontal bars 111. The vertical bars 112 are coplanar with the horizontal bars 111. The reinforcing bars 113 are used to increase the strength of the skeleton 11 and realize the fixation and connection between the inner layer panel 1 and the surface panel 3. Each vertical bar 112 corresponds to one reinforcing bar 113. Multiple reinforcing bars 113 are arranged parallel to the vertical bars 112. The reinforcing bars 113 are parallel to the plane where the horizontal bars 111 and vertical bars 112 are located, and are connected to the vertical bars 112 through connecting bars 114. Multiple connecting bars 114 are arranged in parallel and are perpendicular to the plane where the horizontal bars 111 and vertical bars 112 are located. It is understood that the above-mentioned steel bars are all made of the same material. Those skilled in the art can select the diameter of the steel bars according to the load conditions. For example, FRP bars can be selected. The initial design of the steel bar diameter is 3 to 32 mm. Here, FRP bars are formed by gluing multiple strands of continuous fibers (such as glass fiber, carbon fiber, etc.) together with a base material (such as polyamide resin, polyethylene resin, epoxy resin, etc.) and then extruding and drawing them through a special mold.

[0032] The panel 12 here is used to accommodate the frame 11. Its material includes, but is limited to, UHPC material. UHPC is a cement-based engineering material with good durability and excellent wear resistance and impact resistance. After the frame 11 is fixed, UHPC is cast using a mold. The outer side of the panel 12 is provided with multiple parallel protruding ribs 121 for accommodating and fixing the aforementioned reinforcing ribs 113. The two sides of the protruding ribs 121 are set with bevels. The protruding ribs adopt a joint-like skeleton shape design, which provides in-plane and out-of-plane constraints for the wall panel while minimizing stress concentration at the edges and corners, and can fully exert its own strength. It can be understood that a boundary line 122 of two bevels will be formed between two adjacent protruding ribs 121. The two bevels are symmetrical along the boundary line 122. Thus, multiple protruding ribs 121 are combined together to form an undulating inclined overlapping surface on the outer side of the panel 12, which is used to interlock with the inner side of the cladding panel 3 to form a resistance supplement, thereby increasing the strength of the wall. It should be noted that, similar to the inner layer 1 mentioned above, the panel 12 is cast using a mold. The mold is pre-set with the shape of the cast panel 12, meaning that the mold also has the aforementioned protruding ribs 121 and the inclined surfaces on both sides. Preferably, the thickness of the panel 12 is 5 to 500 mm, and the strength is not less than 50 MPa, thereby ensuring that the wall panel has good sound insulation and strength.

[0033] The aerogel coating 2 has excellent sound insulation and thermal insulation effects. When applied between panel 12 and surface panel 3, it significantly improves the overall sound insulation and thermal insulation performance of the wall panel. The aerogel coating 2 is sprayed onto the outer side of the inner panel 1, serving both sound insulation and thermal insulation purposes, and also bonding the inner panel 1 and surface panel 3. It forms an adhesive force at the interface between the inner panel 1 and surface panel 3, thereby increasing the connection strength between them. Preferably, the thickness of the aerogel coating 2 is 1mm to 3mm to ensure the sound insulation effect of the wall panel, and its thermal conductivity is less than 0.05W / (m·k), thus ensuring the thermal insulation effect of the wall panel. Table 1 below shows the data on the gain effect of the aerogel coating on the thermal insulation performance of the wall panel.

[0034] Table 1. Data on the effect of aerogel coating on the thermal insulation performance of wall panels.

[0035]

[0036] As shown in Table 1, taking a 100mm thick UHPC wall panel as an example, its average heat transfer coefficient is as high as 5 [W / (m²]. 2 Applying aerogel coatings of 1mm, 2mm, and 3mm thickness to the wall surface can reduce its average heat transfer coefficient to 1.88 [W / (m²]. 2 ·K)]、1.15[W / (m 2 ·K)]、0.83[W / (m 2The maximum reduction is as high as 83%, and the thermal insulation performance is significantly improved.

[0037] The facing panel 3 is disposed on the outer side of the aerogel coating 2. Specifically, the facing panel 3 can be inserted into or cast onto the outer side of the aerogel coating. Multiple grooves 31, adapted to the protruding ribs 121, are provided parallel to each other on the inner side of the facing panel 3. The arrangement of the protruding ribs 121 and the grooves 31 forms a mechanical interlocking force. Furthermore, the two sides of the grooves 31 are inclined, and a boundary line 32 is formed between two adjacent grooves 31. The two inclined surfaces are symmetrical along the boundary line 32, adapting to the inclined surfaces on both sides of the protruding ribs 121, thereby forming an inclined overlapping interface, thus providing resistance supplementation and increasing the safety redundancy of the wall panel. It is understood that those skilled in the art can select rigid or flexible decorative panels according to the facade design requirements.

[0038] It is understandable that those skilled in the art can set the dimensions of each layer of the wall panel structure as needed. In a specific example, combined with... Figure 1 , Figure 3 and Figure 4 As shown, the size of a wall panel unit is defined by the center of the intersection of the horizontal reinforcement 111, the vertical reinforcement 112, and the connecting reinforcement 114, and by the size of the area formed between two adjacent horizontal reinforcement 111 and vertical reinforcement 112. Figure 1 The dotted area A in the diagram represents a wall panel unit. The length L and height H of the wall panel unit are preferably no greater than 200mm, and the thickness D is preferably no greater than 60mm. The length L and height H of the wall panel unit are preferably equal, meaning the cross-section of the wall panel unit is square. This diagram provides preferred spacing limits for the horizontal and vertical reinforcement bars of the skeleton and preferred constraint width limits for the panel ribs. The length of the wall panel unit is defined as: firstly, the recommended spacing of the horizontal and vertical reinforcement bars of the skeleton, ensuring the skeleton's support function and meeting the wall panel's load-bearing and rib anchoring requirements; and secondly, the recommended constraint width of the panel ribs, ensuring sufficient constraint for the aerogel layer and the facing panel, preventing shear failure of the ribs. The preferred thickness limit of the wall panel unit is the result of the combined effect of wall panel material zoning and structural design, aiming to achieve the performance goals of thin wall panels, high load-bearing capacity, and strong thermal insulation. It should be noted that the wall panel can be divided into several wall panel units. Here, the wall panel unit does not mean that the wall panel is physically divided according to the unit size. Several wall panel units can be cast into a wall panel at one time, or they can be cast into a specific size and spliced ​​into a whole wall panel according to a certain connection method. If splicing is adopted, the horizontal reinforcement inside the splicing large unit (here, the large unit contains no less than one wall panel unit) is not connected through the seam, but a space is reserved for grouting of the reinforcement. The large unit is connected to form an integral wall panel through secondary grouting of the reinforcement.

[0039] Furthermore, the maximum distance between the inner side surface of the inner plate 1 and the inclined surface of the inner plate 1 is D1, the width of the protruding rib 121 is D0≥0.5D1, the length of the protruding rib 121 is L0≥0.15L, and the length and width of the cross-section of the protruding rib are positively correlated with the thickness of the constrained unit plate and the width of the unit, respectively. Within the above preferred relationship range, it can be ensured that the strength of the protruding rib itself is higher than the required constraining stress. In addition, various diameter steel bars can be set in the preferred cross-section of the protruding rib to improve the stress performance of the protruding rib.

[0040] Furthermore, the minimum distance between the inner side surface and the outer slope of the inner layer 1 is D2, which is equal to the maximum distance between the outer side surface and the inner slope of the surface panel 3; preferably, the included angle between the outer slope and the inner side surface of the inner layer 1 is θ, tanθ=2(D1-D2) / L, where equal to can also be approximately equal to, and can be dynamically adjusted by those skilled in the art according to actual needs. The setting of the included angle θ is to provide reinforcement for the convex rib in the lateral constraint, and its range is determined by the limit values ​​of wall thickness and unit size.

[0041] When using wall panels, such as Figure 5 As shown, along the y-axis direction of the line containing the transverse rib 111, the wall panel resists in-plane loads through the mechanical interlocking force τ1 of the protruding rib 121, the frictional force τ2 of the overlapping interface, and the adhesive force τ3 of the aerogel coating 2. Thus, an interlock is formed in the y-axis direction between the inner panel 1, the aerogel coating 2, and the surface panel 3; Figure 6 As shown, along the x-axis direction of the connecting rib 114, the wall panel resists out-of-plane loads through the mechanical interlocking force σ1 of the protruding rib 121 and the frictional force σ2 of the overlapping interface. This creates an interlocking mechanism in the x-axis direction between the inner layer 1, the aerogel coating 2, and the surface panel 3, achieving a two-way interlocking mechanism between the heterogeneous material layers of the inner layer 1, the aerogel coating 2, and the surface panel 3. Here, in-plane load refers to loads parallel to the large surface of the wall panel, and out-of-plane load refers to loads perpendicular to the large surface of the wall panel. It should be noted that, for ease of description, the direction of the horizontal rib 111 is defined as the y-axis direction, the direction of the connecting rib 114 is defined as the x-axis direction, and the direction of the vertical rib 112 is defined as the z-axis direction. The x, y, and z axes are perpendicular to each other.

[0042] In some preferred embodiments, on the one hand, the two sides of the convex rib 121 on the inner layer plate 1 (panel 12) are provided with convex or concave surfaces, that is, the two adjacent convex ribs 121 are provided with concave or convex surfaces, thereby forming an inclined surface overlapping state on the outer side of the inner layer plate 1. Correspondingly, the two sides of the groove 31 of the surface panel 3 are provided with concave or convex surfaces, and the two adjacent grooves 31 of the surface panel 3 are provided with convex or concave surfaces, thereby forming an inclined surface overlapping state on the inner side of the surface panel 3. In other words, when the two sides of the convex rib 121 on the inner layer 1 are convex, that is, when the two adjacent convex ribs 121 on the inner layer 1 are concave, the two sides of the groove 31 on the surface panel 3 are concave, and the two adjacent grooves 31 on the surface panel 3 are convex. Conversely, when the two sides of the convex rib 121 on the inner layer 1 are concave, that is, when the two adjacent convex ribs 121 on the inner layer 1 are convex, the two sides of the groove 31 on the surface panel 3 are convex, and the two adjacent grooves 31 on the surface panel 3 are concave. Thus, from the perspective of the entire inner layer 1 and surface panel 3, the inner layer 1 and surface panel 3 form an inclined overlapping and interlocking state, thereby forming a resistance supplement and increasing the safety redundancy of the wall panel. On the other hand, through the interlocking arrangement of the convex rib 121 on the inner layer 1 and the groove 31 on the surface panel 3, the mutual embedding between the inner layer 1, the aerogel coating 2 and the surface panel 3 is realized, so as to ensure the connection strength between the wall panel layers.

[0043] In some preferred embodiments, the outer contour of the aforementioned rib 121 is smoothly designed to disperse the concentration of force and reduce the weakening of the interlocking mechanism due to stress concentration. Furthermore, the cross-section of the rib 121 can be femoral head shaped, i.e., a biomimetic design. From the cross-section of the rib 121, the two sides of the bottom end of the rib 121 are concave inward, thereby engaging with the groove 31 of the surface panel 3 to form an interlocking action.

[0044] This utility model provides a wall panel with a biomimetic interlocking structure. The layer structure specifically includes an inner layer panel, an aerogel coating, and a surface panel. It has strong sound insulation and heat insulation effects. At the same time, the outer side of the inner layer panel is provided with multiple parallel protruding ribs, which are arranged at an angle. The inner side of the surface panel is provided with multiple parallel grooves that are adapted to the protruding ribs, which are also arranged at an angle. When the wall panel is in use, along the direction of the horizontal ribs, the wall panel resists the in-plane load through the mechanical interlocking force of the protruding ribs, the friction of the overlapping interface, and the adhesive force of the aerogel coating. Along the direction of the connecting ribs, the wall panel resists the out-of-plane load through the mechanical interlocking force of the protruding ribs and the friction of the overlapping interface. This realizes a two-way interlocking mechanism of heterogeneous material layers, thereby ensuring the strength of the wall.
