Description

Technical Field

[0001] This invention relates to the field of construction, and more particularly to a wall panel with an interlocking structure. Background Technology

[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. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a wall panel structure with an interlocking mechanism, comprising an inner layer panel, an aerogel coating, and a surface panel, thereby ensuring the sound insulation and heat preservation effect of the wall panel. The inner layer panel includes a frame and a panel; the frame includes multiple horizontal ribs, vertical ribs, and protruding ribs; the outer side of the panel has multiple protrusions; the inner side of the surface panel has multiple grooves that match the protrusions, forming a mechanical interlocking force through the arrangement of the protrusions and grooves; furthermore, the grooves are sloped around their perimeter, matching the sloped perimeter of the protrusions, thereby forming an interlocking mechanism. The obliquely overlapping and interlocking interfaces form a resistance supplement, increasing the safety redundancy of the wall panel. When the wall panel is in use, along the y-axis direction where the horizontal ribs are located and the z-axis direction where the vertical ribs are located, the wall panel resists in-plane loads through the mechanical interlocking force of the ribs, the frictional force of the overlapping interface, and the adhesive force of the aerogel coating. Along the x-axis direction, which is perpendicular to both the horizontal and vertical ribs, the wall panel resists out-of-plane loads through the mechanical interlocking force of the protrusions and the frictional force of the overlapping interface. This forms a three-dimensional interlocking mechanism of the heterogeneous material layers, thereby ensuring the strength of the wall and making it less prone to falling off.

[0005] To achieve the above objectives, the present invention provides a wall panel with an interlocking structure, comprising an inner layer panel, an aerogel coating, and a surface panel; wherein,

[0007] The aerogel coating is sprayed on the outside of the inner layer panel to bond the inner layer panel and the surface panel, forming an adhesive force at the interface between the inner layer panel and the surface panel.

[0008] The surface panel is disposed on the outside of the aerogel coating, and the inner side of the surface panel is provided with multiple grooves that are adapted to the protrusions. The mechanical interlocking force is formed by the arrangement of the protrusions and grooves. Furthermore, the grooves are arranged with bevels around them, which are adapted to the bevels around the protrusions, thereby forming an inclined overlapping and interlocking interface, thus forming a resistance supplement and increasing the safety redundancy of the wall panel.

[0009] When the wall panel is in use, along the y-axis direction where the horizontal ribs are located and the z-axis direction where the vertical ribs are located, the wall panel resists in-plane loads through the mechanical interlocking force of the ribs, the frictional force of the overlapping interface, and the adhesive force of the aerogel coating; along the x-axis direction, which is perpendicular to both the horizontal and vertical ribs, the wall panel resists out-of-plane loads through the mechanical interlocking force of the protrusions and the frictional force of the overlapping interface, thus forming a three-dimensional interlocking mechanism of the heterogeneous material layer.

[0010] Preferably, one end of the convex rib is located at the intersection of the horizontal and vertical ribs, and the other end is in the shape of a ring, parallel to the plane where the horizontal and vertical ribs are located.

[0011] Preferably, the surface panel is cast onto the outside of the gel coating.

[0012] Preferably, the distance between two adjacent horizontal ribs is equal to the distance between two adjacent vertical ribs;

[0013] With the convex rib reinforcement as the center, the distance between two adjacent horizontal reinforcements is the variable side length, forming a wall panel unit;

[0014] Within the wall panel unit, the outer surface of the panel is concave inward along the y-axis direction of the horizontal ribs and the z-axis direction of the vertical ribs, centered on the convex rib reinforcement; the aerogel coating is sprayed on the outer side of the inner layer panel; correspondingly, the inner surface of the veneer panel is convex inward along the y-axis direction of the horizontal ribs and the z-axis direction of the vertical ribs, centered on the groove, thereby achieving a bidirectional inclined overlapping interface; and the mutual embedding between the various structural layers is achieved through the protrusions on the panel and the grooves on the veneer panel.

[0015] More preferably, the side length L of the wall panel unit is no greater than 200mm and the thickness D is no greater than 60mm.

[0016] More preferably, within the wall panel unit, the maximum distance between the outer side surface of the veneer and the inner inclined surface of the veneer is D1, the width of the protrusion D0 ≥ 0.5D1, and the length of the protrusion L0 ≥ 0.15L.

[0017] More preferably, the minimum distance between the inner side surface of the panel and the inclined surface of the panel is D2, where D2 = D - D1;

[0020] Preferably, the thickness of the aerogel coating is 1 mm to 3 mm, and the thermal conductivity is less than 0.05 W / (m·k).

[0021] Preferably, the cross-section of the protrusion is femoral head shaped.

[0022] This invention provides a wall panel with an interlocking structure. The layer structure includes an inner layer panel, an aerogel coating, and a surface panel, thereby ensuring the sound insulation and heat preservation effect of the wall panel. The inner layer panel includes a frame and a panel. The frame includes multiple horizontal ribs, vertical ribs, and protruding ribs. The outer side of the panel has multiple protrusions. The inner side of the surface panel has multiple grooves that match the protrusions, forming a mechanical interlocking force through the arrangement of the protrusions and grooves. Furthermore, the grooves are sloped around their perimeter, matching the sloped perimeter of the protrusions, thereby forming an inclined overlapping interlocking structure. The interlocking interface forms a resistance supplement, increasing the safety redundancy of the wall panel. When the wall panel is in use, along the y-axis direction where the horizontal ribs are located and the z-axis direction where the vertical ribs are located, 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 x-axis direction, which is perpendicular to both the horizontal and vertical ribs, the wall panel resists out-of-plane loads through the mechanical interlocking force of the protrusions and the frictional force of the overlapping interface. This forms a three-dimensional interlocking mechanism of the heterogeneous material layer, thereby ensuring the strength of the wall and making it less prone to falling off.

[0031] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Figure 1 This is a schematic diagram of a cross-section of a wall panel with an interlocking structure provided in an embodiment of the present invention. Figure 2 This is a structural schematic diagram of a wall panel unit provided in an embodiment of the present invention. Figure 3 This is an exploded view of a wall panel unit provided in an embodiment of the present invention. It can be understood that... Figure 1 The area A marked by the dashed line represents a wall panel unit, combined with... Figures 1 to 3 As shown, the wall panel layer structure with interlocking structure provided in this embodiment of the invention includes, from the inside out, an inner layer 1, an aerogel coating 2, and a surface panel 3. The structure between each layer of the wall panel will be described in detail below.

[0033] The inner panel 1 specifically includes a frame 11 and a panel 12, which is a cement panel 12 with a frame 11.

[0034] 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, and raised rib reinforcement 113. 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, perpendicular to the horizontal bars 111, and coplanar with the horizontal bars 111. Figure 4 As shown, the protruding rib reinforcement is located at the intersection of the horizontal reinforcement 111 and the vertical reinforcement 112, and is not coplanar with the horizontal reinforcement 111 and the vertical reinforcement 112. It is a protruding steel bar with a special structure, used to achieve the interlocking between the inner layer plate 1 and the surface panel 3. 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 bonding multiple strands of continuous fibers (such as glass fiber, carbon fiber, etc.) with a base material (such as polyamide resin, polyethylene resin, epoxy resin, etc.), and then extruding and drawing them through a special mold.

[0035] The panel 12 here is used to house the frame 11, and its material includes, but is limited to, UHPC. 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 poured using a mold, combined with... Figure 4 As shown, Figure 4The image shows a side view of the wall panel unit from four directions. Multiple protrusions 121 are provided on the outer side of the panel 12 for fixing and wrapping the raised rib reinforcement 113. The protrusions 121 are arranged at an angle around their centers. Preferably, the panel 12 has a thickness of 5 to 500 mm and a strength of not less than 100 MPa, thereby ensuring the sound insulation, heat preservation, and strength of the wall panel.

[0036] 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 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. It can be understood that because the aerogel is sprayed onto the outer side of the inner panel 1, its shape is the same as the outer surface shape of the inner panel 1, forming a corresponding protrusion 121 structure and a convex surface extending inwards from the protrusion 121 as the center. Specifically, as shown... Figure 6 As shown. Preferably, the thickness of the aerogel coating 2 is 1 mm to 3 mm, thereby ensuring the sound insulation effect of the wall panel. The thermal conductivity is less than 0.05 W / (m·k), thereby 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.

[0037] Table 1. Data on the effect of aerogel coating on the thermal insulation performance of wall panels.

[0038]

[0039]

[0040] As shown in Table 1, taking a 240mm thick ordinary sintered clay brick wall as an example, its average heat transfer coefficient is as high as 1.59 [W / (m²]]. 2 Applying aerogel coatings of 1mm, 2mm, and 3mm thickness to the wall surface can reduce its average heat transfer coefficient to 1.04 [W / (m²).] 2 ·K)]、0.77[W / (m 2 ·K)]、0.61[W / (m 2 The maximum reduction is as high as 62%, and the thermal insulation performance is significantly improved.

[0041] The facing panel 3 is disposed on the outside of the aerogel coating 2, and is cast onto the outside of the aerogel coating. The outer surface of the facing panel has a planar structure, such as... Figure 7As shown, the inner side of the cladding panel 3 is provided with multiple grooves 31 that are adapted to the protrusions 121. The arrangement of the protrusions 121 and the grooves 31 forms a mechanical interlocking force. Furthermore, the grooves 31 are sloped around their perimeter, adapting to the sloped perimeter of the protrusions 121, thereby forming an inclined overlapping and interlocking 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.

[0042] When the wall panel is in use, along the y-axis direction where the horizontal ribs 111 are located and the z-axis direction where the vertical ribs 112 are located, 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 2. This creates an interlocking mechanism in the y-axis and z-axis directions between the inner layer panel 1, the aerogel coating 2, and the surface panel 3. Along the x-axis direction, which is perpendicular to both the horizontal ribs 111 and the vertical ribs 112, the wall panel resists out-of-plane loads through the mechanical interlocking force of the protrusions 121 and the frictional force of the overlapping interface. This creates an interlocking mechanism in the x-axis direction between the inner layer panel 1, the aerogel coating 2, and the surface panel 3, thus achieving a three-dimensional interlocking mechanism between the heterogeneous material layers of the inner layer panel 1, the aerogel coating 2, and the surface panel 3. Here, in-plane loads refer to loads parallel to the large surface of the wall panel, and out-of-plane loads refer to loads perpendicular to the large surface of the wall panel. It should be noted that, for ease of description, the direction of the straight line where the horizontal rib 111 is located is defined as the y-axis direction, the direction of the straight line where the vertical rib 112 is located is defined as the z-axis direction, and the direction that is perpendicular to both the horizontal rib 111 and the vertical rib 112 is defined as the x-axis direction. The x-axis, y-axis, and z-axis are perpendicular to each other.

[0043] In some preferred embodiments, one end of the raised rib 113 on the skeleton 11 is located at the intersection of the horizontal rib 111 and the vertical rib 112, and the other end is annular, parallel to the plane containing the horizontal rib 111 and the vertical rib 112. It is understood that during the casting of the panel 12, a protrusion 121 will be formed at the raised rib, fixing and enclosing the raised rib 113. Preferably, the cross-section of the protrusion 121 can be femoral head shaped, i.e., a biomimetic type. From the cross-section of the raised rib, the two sides of the bottom end of the raised rib are concave inward, thereby engaging with the groove 31 of the surface panel 3 to form an interlocking action.

[0044] In some preferred embodiments, the distance between two adjacent horizontal ribs 111 is equal to the distance between two adjacent vertical ribs 112; then, with the rib 113 as the center, the distance between two adjacent horizontal ribs 111 is a variable side length, forming a square wall panel unit; within the wall panel unit, the outer surface of the panel 12 is concave inward along the y-axis direction where the horizontal ribs 111 are located and the z-axis direction where the vertical ribs 112 are located, centered on the rib 113. It can be understood that an inwardly concave slope is formed on the outer surface of the panel 12 with the rib 113 as the center, and the slope is symmetrically arranged along both the y-axis and z-axis directions with the rib 113 as the center; the aerogel coating 2 is sprayed onto the outer side of the inner layer panel 1, forming a coating with the same shape as the outer surface of the inner layer panel 1; correspondingly, the surface panel 3 is cast onto the outer side of the aerogel coating 2, thereby forming a groove 31 corresponding to the protrusion 121 in the middle of the surface panel 3, and the groove 31 is centered on the inner surface of the surface panel 3 along the horizontal ribs 111. The 11-axis section and the z-axis section of the vertical rib 112 protrude inwards. This means that, on the inner side of the panel 3, with the groove 31 as the center, outwardly convex slopes are formed around the groove 31. These slopes, centered on the groove 31, are symmetrically arranged along both the y-axis and z-axis directions. This creates a bidirectional inclined overlapping interface between the panel 12 and the panel 3. The interlocking design of these interfaces achieves interlocking in the y-axis and z-axis directions. Multiple wall panel units can be combined to form a large, integrated wall panel. For the entire wall, the overlapping interface between the panel 12 and the panel 3 is convex and concave, interlocking with each other to ensure the overall strength of the wall. Furthermore, in the x-axis direction, the protrusion 121 on the panel 12 and the groove 31 on the panel 3 further solidify the interlocking between different structural layers, achieving interlocking in the x, y, and z-axis directions and increasing the strength of the wall panel.

[0045] It should be noted that the wall panel can be divided into several wall panel units. These wall panel units can be cast into a single wall panel in one go, or they can be cast into a specific size and spliced ​​together in a certain connection method to form a whole wall panel. If splicing is used, the horizontal reinforcement inside the splicing large unit (which may contain no less than one wall panel unit) is not connected with seams, but rather space is reserved for grouting of the reinforcement. The large unit is then connected to form a whole wall panel through secondary grouting of the reinforcement.

[0046] Preferred, combined Figure 2As shown, the side length L of the wall panel unit should not exceed 200mm, and the thickness D should not exceed 60mm. The length of the wall panel unit (i.e., the dimensions of the unit's large surface in two directions) serves two purposes: first, it represents the recommended spacing of the horizontal and vertical reinforcing bars in the framework, ensuring the framework's support function and meeting the wall panel's load-bearing and protrusion anchoring requirements; second, it represents the recommended constraint range for the panel protrusions, ensuring sufficient constraint for the aerogel layer and the facing panel, preventing shear failure of the protruding rib reinforcement. The wall panel unit thickness limit here 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.

[0047] Preferred, combined Figure 5 and Figure 8 As shown, within the wall panel unit, the maximum distance between the outer side of the surface panel 3 and the inner inclined surface of the surface panel 3 is D1, the width of the protrusion 121 D0≥0.5D1, and the length of the protrusion 121 L0≥0.15L.

[0048] Understandably, the protrusion offers the following advantages in terms of shape: Its articulated, skeletal design provides in-plane and out-of-plane constraints on the wall panel while minimizing stress concentration at sharp corners, thus maximizing its own strength. It also offers the following dimensional advantages: the height and width of the protrusion's cross-section are positively correlated with the thickness of the constraint unit's surface plate and the width of the unit, respectively. Within the recommended ratio range, this ensures that the protrusion's own strength exceeds the required constraint stress. Furthermore, the recommended protrusion cross-section can accommodate reinforcing bars of various diameters, improving its load-bearing capacity.

[0049] Further optimized, combined Figure 5 and Figure 8 As shown, the minimum distance between the inner side of panel 12 and the inclined surface of panel 12 is D2, where D2 = D - D1; the angle between the outer inclined surface and the inner side of panel 12 is θ, where tan = 2(D1 - D2) / L. Here, "equal to" can also mean "approximately equal to". Those skilled in the art can adjust it dynamically according to actual needs. The setting of the angle θ is to provide reinforcement for the protrusion in terms of lateral constraint. Its range is determined by the limits of wall thickness and unit size. Since it is not the main source of lateral constraint, its most unfavorable value, i.e., 0°, is also acceptable, and therefore no specific constraint is imposed on its range.

[0050] This invention provides a wall panel with an interlocking structure. The layer structure includes an inner layer panel, an aerogel coating, and a surface panel, thereby ensuring the sound insulation and heat preservation effect of the wall panel. The inner layer panel includes a frame and a panel. The frame includes multiple horizontal ribs, vertical ribs, and protruding ribs. The outer side of the panel has multiple protrusions. The inner side of the surface panel has multiple grooves that match the protrusions, forming a mechanical interlocking force through the arrangement of the protrusions and grooves. Furthermore, the grooves are sloped around their perimeter, matching the sloped perimeter of the protrusions, thereby forming an inclined overlapping interlocking structure. The interlocking interface forms a resistance supplement, increasing the safety redundancy of the wall panel. When the wall panel is in use, along the y-axis direction where the horizontal ribs are located and the z-axis direction where the vertical ribs are located, 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 x-axis direction, which is perpendicular to both the horizontal and vertical ribs, the wall panel resists out-of-plane loads through the mechanical interlocking force of the protrusions and the frictional force of the overlapping interface. This forms a three-dimensional interlocking mechanism of the heterogeneous material layer, thereby ensuring the strength of the wall and making it less prone to falling off.
