[0027] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments.

[0028] Figure 1 A schematic diagram of a wall panel structure with a bionic interlocking structure provided by an embodiment of the present invention, Figure 2 An exploded schematic diagram of a wall panel with a bionic interlocking structure provided by an embodiment of the present invention is shown in FIG. Figure 1 and Figure 2 As shown, a wall panel with a bionic interlocking structure provided by an embodiment of the present invention comprises an inner layer panel 1, an aerogel coating 2 and a facing panel 3 from the inner to the outer layer structure, and the layer structure of the wall panel is specifically introduced below.

[0029] The inner layer panel 1 may specifically include a frame 11 and a panel 12 , which may be understood as the panel 12 with the frame 11 .

[0030] Specifically, the skeleton 11 here is a load-bearing component, and the skeleton includes but is not limited to various types of reinforcement such as ordinary strength, high strength, FRP, etc., specifically including multiple transverse bars 111, vertical bars 112, reinforcing bars 113 and connecting bars 114. The transverse bars 111 refer to horizontal steel bars, and the vertical bars 112 refer to vertical steel bars. Multiple transverse bars 111 are arranged in parallel, and multiple vertical bars 112 are arranged in parallel and perpendicular to the transverse bars 111. The vertical bars 112 and the transverse bars 111 are coplanar; the reinforcing bars 113 are used to increase the strength of the skeleton 11 and to achieve the fixation and connection between the inner layer panel 1 and the facing panel 3. Each vertical bar 112 corresponds to a reinforcing bar 113, and multiple reinforcing bars 113 are arranged parallel to the vertical bars 112. The reinforcing bars 113 are parallel to the planes where the transverse bars 111 and the 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 the connecting bars 114 are perpendicular to the planes where the transverse bars 111 and the vertical bars 112 are located. It can be understood that the materials of the above-mentioned steel bars are the same, and technical personnel in this field can select the diameter of the steel bars according to the load conditions. For example, FRP bars can be selected, and the initial steel bar diameter is 3 to 32 mm. The FRP bars here are multiple strands of continuous fibers (such as glass fibers, carbon fibers, etc.) that are glued through a base material (such as polyamide resin, polyethylene resin, epoxy resin, etc.) and then extruded and drawn into shape through a special mold.

[0031] The panel 12 here is used to accommodate the skeleton 11, and its material includes but is not limited to UHPC material. UHPC is a cement-based engineering material. UHPC has good durability and excellent wear resistance and anti-explosion performance. After the skeleton 11 is fixed, UHPC is cast with a mold. A plurality of parallel convex ribs 121 are provided on the outside of the panel 12 for accommodating and fixing the above-mentioned reinforcing ribs 113. The two sides of the convex ribs 121 are arranged in an inclined surface. The convex ribs adopt a joint bone-like appearance design. While providing internal and external constraints on the wall panel plane, it minimizes the stress concentration phenomenon at the edges and corners, and can give full play to its own strength. It can be understood that two inclined planes will form a boundary line 122 between two adjacent convex ribs 121, and the two inclined planes are symmetrical along the boundary line 122. Therefore, multiple convex ribs 121 are combined together to form an undulating inclined overlapping surface on the outer side of the panel 12, which is used to be plugged and engaged with the inner side of the veneer 3 to form a resistance supplement, thereby increasing the strength of the wall. It should be noted that a mold is used when pouring the panel 12, and the mold will pre-set the shape of the panel 12 after pouring, that is, the mold is also provided with the above-mentioned ribs 121 and the inclined surfaces on both sides. Preferably, the thickness of the above-mentioned panel 12 is 5 to 500 mm, and the strength is not less than 50 MPa, so as to ensure that the wallboard has good sound insulation effect and strength.

[0032] The aerogel coating 2 has good sound insulation and heat preservation and heat insulation effects. It is arranged between the panel 12 and the veneer 3 to greatly improve the overall sound insulation and heat preservation effects of the wall panel. The aerogel coating 2 is sprayed on the outside of the inner panel 1. On the one hand, it is used for sound insulation and heat preservation. On the other hand, it is used to bond the inner panel 1 and the veneer 3 to form a bonding force at the interface between the inner panel 1 and the veneer 3, thereby improving the connection strength between the two. Preferably, the thickness of the aerogel coating 2 is 1mm to 3mm, thereby ensuring the sound insulation effect of the wall panel, and the thermal conductivity is less than 0.05W / (m·k), thereby ensuring the heat preservation effect of the wall panel. The following Table 1 shows the data on the gain effect of the aerogel coating on the heat preservation and heat insulation performance of the wall panel.

[0033] Table 1 Data on the thermal insulation performance gain of aerogel coating on wall panels

[0034]

[0035] As shown in Table 1, taking a 100 mm thick UHPC wall panel as an example, its average heat transfer coefficient is as high as 5 [W / (m 2 ·K)], applying 1mm, 2mm, and 3mm thick aerogel coatings on the wall can reduce its average heat transfer coefficient to 1.88[W / (m 2 ·K)], 1.15[W / (m 2 ·K)], 0.83[W / (m 2 ·K)]", with the maximum reduction reaching 83%, and the thermal insulation performance improved significantly.

[0036] The veneer panel 3 is arranged on the outside of the aerogel coating 2. Specifically, the veneer panel 3 can be inserted or cast on the outside of the gel coating. A plurality of grooves 31 are arranged in parallel on the inner side of the veneer panel 3, which are matched with the convex ribs 121. The convex ribs 121 and the grooves 31 form a mechanical bite force. Moreover, the grooves 31 are arranged in a bevel on both sides, and a junction line 32 of two bevels is formed between two adjacent grooves 31. The two bevels are symmetrical along the junction line 32, and are matched with the bevels on both sides of the convex ribs 121, thereby forming an inclined overlapping interface, thereby forming a resistance supplement and increasing the safety redundancy of the wallboard. It is understandable that those skilled in the art can choose rigid or flexible decorative panels according to the requirements of the facade design.

[0037] It is understandable that those skilled in the art can set the dimensions of each layer structure of the wall panel as required. In a specific example, Figure 1 , Figure 3 and Figure 4 As shown, the size of a wall panel unit is defined by the intersection center of the horizontal reinforcement 111, the vertical reinforcement 112 and the connecting reinforcement 114 and the size of the area formed between two adjacent horizontal reinforcements 111 and vertical reinforcements 112. Figure 1The dotted area A in the figure is a wall panel unit. The length L and height H of the wall panel unit are preferably not more than 200 mm, and the thickness D is preferably not more than 60 mm. The length L and height H of the wall panel unit are preferably equal, that is, the cross-section of the wall panel unit is a square. The wall panel unit here gives the preferred spacing limit of the horizontal and vertical reinforcements of the skeleton and the preferred constraint width limit of the panel ribs. The length of the wall panel unit is divided into the recommended spacing of the horizontal and vertical reinforcements of the skeleton, which can ensure the support of the skeleton and meet the wall panel bearing and rib anchoring requirements; the second is the recommended constraint width of the panel ribs, which can ensure that the ribs provide sufficient constraints for the aerogel layer and the veneer to avoid shear damage of the ribs; the preferred limit of the wall panel unit thickness is the result of the combined effect of the wall panel material partitioning and structural design, and the purpose is to achieve the performance goals of thin wall panels, large load-bearing and strong thermal insulation. It should be noted that the wall panel can be divided into several wall panel units. The wall panel units here do not mean that the wall panel is physically divided according to the unit size. Several wall panel units can be cast at one time to form a wall panel, 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 transverse reinforcement inside the large unit (here the large unit contains no less than 1 wall panel unit) is not connected through seams, but space for tensioning and grouting is reserved, and the large units are connected through secondary tensioning and grouting to form an integral wall panel.

[0038] Furthermore, the maximum distance between the inner side surface of the inner layer plate 1 and the inclined surface of the inner layer plate 1 is D1, the width D0 of the convex rib 121 is ≥0.5D1, the length L0 of the convex rib 121 is ≥0.15L, and the length and width of the convex rib cross-section are positively correlated with the thickness of the constraint unit test plate and the unit width, respectively. Within the above preferred relationship range, it can be ensured that the strength of the convex rib itself is higher than the required constraint stress. In addition, a variety of diameters of steel bars can be provided in the preferred convex rib cross-section to improve the force-bearing performance of the convex rib.

[0039] Furthermore, the minimum distance between the inner side surface and the outer inclined surface of the inner layer panel 1 is D2, which is equal to the maximum distance between the outer side surface and the inner inclined surface of the facing panel 3; preferably, the angle between the outer inclined surface and the inner side surface of the inner layer panel 1 is θ, tanθ=2(D1-D2) / L, where "equal to" can also be approximately equal to, and technical personnel in this field can dynamically adjust it according to actual needs. The setting of the angle θ is to provide a reinforcement for the convex rib in lateral constraint, and its range is determined by the limit values ​​of the wall thickness and the unit size.

[0040] When using wall panels, Figure 5 As shown, along the y-axis direction of the straight line where the transverse rib 111 is located, the wall panel resists the in-plane load through the mechanical bite force τ1 of the convex rib 121, the friction force τ2 of the overlapping interface and the bonding force τ3 of the aerogel coating 2, thereby forming an interlock in the y-axis direction between the inner layer board 1, the aerogel coating 2 and the veneer board 3; Figure 6As shown, along the x-axis direction of the straight line where the connecting rib 114 is located, the wall panel resists the out-of-plane load through the mechanical bite force σ1 of the convex rib 121 and the friction force σ2 of the overlapping interface, thereby forming an interlocking in the x-axis direction between the inner layer panel 1, the aerogel coating 2 and the veneer panel 3, thereby realizing a two-way interlocking mechanism between the heterogeneous material layers of the inner layer panel 1, the aerogel coating 2 and the veneer panel 3. The in-plane load here refers to the load parallel to the large surface of the wall panel, and the out-of-plane load here refers to the load perpendicular to the large surface of the wall panel. It should be noted that, for the convenience of description, the straight line direction where the horizontal rib 111 is located is defined as the y-axis direction, the straight line direction where the connecting rib 114 is located is defined as the x-axis direction, and the straight line direction where the vertical rib 112 is located is defined as the z-axis direction, and the x-axis, y-axis, and z-axis are perpendicular to each other.

[0041] In some preferred embodiments, on the one hand, the two sides of the convex rib 121 on the inner layer panel 1 (panel 12) are convex or concave, that is, the space between two adjacent convex ribs 121 is concave or convex, thereby forming an inclined surface overlap state on the outer side surface of the inner layer panel 1, and correspondingly, the two sides of the groove 31 of the facing plate 3 are concave or convex, and the space between two adjacent grooves 31 of the facing plate 3 is convex or concave, thereby forming an inclined surface overlap state on the inner side surface of the facing plate 3. That is to say, when the two sides of the convex rib 121 on the inner layer panel 1 are convex, that is, the space between two adjacent convex ribs 121 on the inner layer panel 1 is concave, correspondingly, the two sides of the groove 31 of the facing panel 3 are concave, and the space between two adjacent grooves 31 of the facing panel 3 is convex; conversely, when the two sides of the convex rib 121 on the inner layer panel 1 are concave, that is, the space between two adjacent convex ribs 121 on the inner layer panel 1 is convex, correspondingly, the two sides of the groove 31 of the facing panel 3 are convex, and the space between two adjacent grooves 31 of the facing panel 3 is concave. From the perspective of the entire inner layer panel 1 and the facing panel 3, the inner layer panel 1 and the facing panel 3 form an overlapping and interlocking state of inclined surfaces, thereby forming a resistance supplement and increasing the safety redundancy of the wall panel; on the other hand, through the interlocking setting of the convex rib 121 on the inner layer panel 1 and the groove 31 of the facing panel 3, the inner layer panel 1, the aerogel coating 2 and the facing panel 3 The layers of the structure are mutually embedded to ensure the connection strength between the wall panel partitions.

[0042] In some preferred embodiments, the outer contour of the rib 121 is smooth, which can disperse the concentration of force and reduce the weakening of the interlocking mechanism caused by stress concentration. Furthermore, the cross section of the rib 121 can be a femoral head type, that is, a bionic type. From the cross section of the rib 121, the two sides of the bottom end of the rib 121 are concave inward, so as to be snap-fitted with the groove 31 of the veneer plate 3 to form a bite.

[0043] A wall panel with a bionic interlocking structure provided by an embodiment of the present invention has a layer structure specifically including an inner layer panel, an aerogel coating and a surface panel, and has strong sound insulation and heat insulation effects. At the same time, a plurality of parallel convex ribs are provided on the outer side of the inner layer panel, and are arranged in an inclined surface; a plurality of parallel grooves matching the convex ribs are provided on the inner side of the surface panel, and are arranged in an inclined surface. When the wall panel is in use, along the direction of the transverse reinforcement, the wall panel resists the in-plane load through the mechanical bite force of the convex ribs, the friction force of the overlapping interface and the bonding force of the aerogel coating; along the direction of the connecting reinforcement, the wall panel resists the out-of-plane load through the mechanical bite force of the convex ribs and the friction force of the overlapping interface, thereby realizing a two-way interlocking mechanism of the heterogeneous material layers, thereby ensuring the strength of the wall.
