Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a wall panel with an interlocking structure. Background Art

[0002] With the increase of residential, apartment, office, teaching, hospital and other buildings, the requirements for building sound insulation and thermal insulation are getting higher and higher. Ordinary wall materials cannot effectively isolate the sound insulation problem caused by vibration. Good sound insulation and thermal insulation environment have become one of the important characteristics of green buildings. Therefore, various structures of exterior wall panels are continuously introduced and widely used in the construction industry.

[0003] At present, the existing exterior wall panels are not strong enough and are easy to fall off after being assembled on the wall, and have poor sound insulation and heat preservation effects. Summary of the invention

[0004] The purpose of the present invention is to provide a wall panel layer structure with an interlocking structure, which includes an inner layer panel, an aerogel coating and a veneer panel, so as to ensure the sound insulation and heat preservation effect of the wall panel; wherein the inner layer panel includes a frame and a panel; the frame includes a plurality of transverse ribs, vertical ribs and convex rib reinforcements; a plurality of protrusions are arranged on the outer side of the panel; a plurality of grooves matching the protrusions are arranged on the inner side of the veneer panel, and a mechanical bite force is formed by the arrangement of the protrusions and the grooves; and the grooves are arranged with inclined surfaces around them, which are matched with the inclined surfaces around the protrusions, thereby forming an inclined surface. The oblique overlapping and interlocking interfaces form a resistance supplement and increase the safety redundancy of the wall panel. When the wall panel is in use, along the y-axis direction of the straight line where the horizontal reinforcement is located and the z-axis direction of the straight line where the vertical reinforcement is located, 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 x-axis direction perpendicular to both the horizontal and vertical reinforcements, the wall panel resists the out-of-plane load through the mechanical bite force of the protrusion and the friction force of the overlapping interface, thereby forming a three-way interlocking mechanism of the heterogeneous material layers, thereby ensuring the strength of the wall and preventing it from falling off.

[0031] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments.

[0032] Figure 1 A schematic structural diagram of a wall panel section with an interlocking structure provided by an embodiment of the present invention, Figure 2 A schematic diagram of the structure of a wall panel unit provided in an embodiment of the present invention, Figure 3 The exploded schematic diagram of a wall panel unit provided by an embodiment of the present invention can be understood as follows: Figure 1 The dotted area A is a wall panel unit. Figures 1 to 3 As shown, the wallboard layer structure with an interlocking structure provided by the embodiment of the present invention includes an inner layer board 1, an aerogel coating 2 and a surface veneer board 3 from the inside to the outside. The structure between the layers of the wallboard is described in detail below.

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

[0034] 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 reinforcements 111, vertical reinforcements 112 and convex rib reinforcements 113. The transverse reinforcements 111 refer to horizontally placed steel bars, and the vertical reinforcements 112 refer to vertically placed steel bars. The multiple transverse reinforcements 111 are arranged in parallel, and the multiple vertical reinforcements 112 are arranged in parallel and perpendicular to the transverse reinforcements 111 and coplanar with the transverse reinforcements 111; Figure 4 As shown, the convex rib reinforcement is arranged 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, which is used to achieve the bite between the inner plate 1 and the veneer plate 3. It can be understood that the material of the above-mentioned steel bars is the same, and 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, 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.) bonded through base materials (such as polyamide resins, polyethylene resins, epoxy resins, etc.), and then extruded and drawn through special molds.

[0035] The panel 12 is used to accommodate the frame 11, and its material includes but is not limited to UHPC material. UHPC is a cement-based engineering material with good durability, excellent wear resistance and anti-explosion performance. After the frame 11 is fixed, the UHPC is poured in a mold, combined with Figure 4 As shown, Figure 4The side view of the wall panel unit in four directions, the outer side of the panel 12 is provided with a plurality of protrusions 121 for fixing and wrapping the rib reinforcement 113, and the protrusions 121 are arranged in an inclined plane around the protrusions 121. Preferably, the thickness of the panel 12 is 5 to 500 mm, and the strength is not less than 100 MPa, so as to ensure the sound insulation and heat preservation effect and strength of the wall panel.

[0036] The aerogel coating 2 has good sound insulation, heat preservation and thermal insulation effects. It is set between the panel 12 and the veneer 3 to greatly improve the overall sound insulation and thermal insulation 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, forming a bonding force at the interface between the inner panel 1 and the veneer 3, thereby improving the connection strength between the two. It can be understood that since the aerogel is sprayed on the outside of the inner panel 1, its shape is the same as the shape of the outer side of the inner panel 1, and a corresponding protrusion 121 structure will be formed, and a convex surface will be formed around the protrusion 121 to the inner side. Specifically, Figure 6 Preferably, the thickness of the aerogel coating 2 is 1 mm to 3 mm, thereby ensuring the sound insulation effect of the wallboard, and the thermal conductivity is less than 0.05 W / (m·k), thereby ensuring the thermal insulation effect of the wallboard. The following Table 1 shows the data of the gain effect of the aerogel coating on the thermal insulation performance of the wallboard.

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

[0038]

[0039]

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

[0041] The veneer plate 3 is arranged on the outside of the aerogel coating 2, and the veneer plate 3 is cast on the outside of the gel coating. The outer side of the veneer plate is a plane structure, such as Figure 7As shown, the inner side of the veneer plate 3 is provided with a plurality of grooves 31 adapted to the protrusions 121, and a mechanical bite force is formed by the arrangement of the protrusions 121 and the grooves 31; and the grooves 31 are arranged with inclined surfaces around them, which are adapted to the inclined surfaces around the protrusions 121, thereby forming an inclined overlapping and interlocking interface, thereby forming a resistance supplement and increasing the safety redundancy of the wallboard. It is understandable that those skilled in the art can select rigid or flexible decorative panels according to the requirements of the facade design.

[0042] When the wall panel is in use, along the y-axis direction of the straight line where the horizontal ribs 111 are located and the z-axis direction of the straight line where the vertical ribs 112 are located, 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 2, thereby forming an interlock in the y-axis and z-axis directions between the inner layer panel 1, the aerogel coating 2 and the veneer panel 3; along the x-axis direction perpendicular to both the horizontal ribs 111 and the vertical ribs 112, the wall panel resists the out-of-plane load through the mechanical bite force of the protrusions 121 and the friction force of the overlapping interface, thereby forming an interlock in the x-axis direction between the inner layer panel 1, the aerogel coating 2 and the veneer panel 3, thereby realizing a three-way interlocking mechanism of 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 ribs 111 are located is defined as the y-axis direction, the straight line direction where the vertical ribs 112 are located is defined as the z-axis direction, and the direction perpendicular to both the horizontal ribs 111 and the vertical ribs 112 is defined as the x-axis direction. The x-axis, y-axis, and z-axis are mutually perpendicular.

[0043] In some preferred embodiments, one end of the convex rib reinforcement 113 on the frame 11 is arranged at the intersection of the horizontal rib 111 and the vertical rib 112, and the other end is in a circular ring shape, parallel to the plane where the horizontal rib 111 and the vertical rib 112 are located. It is understandable that when the panel 12 is cast, a protrusion 121 will be formed at the convex rib reinforcement to fix and wrap the convex rib reinforcement 113. Preferably, the cross-section of the above-mentioned protrusion 121 can be a femoral head type, that is, a bionic type. From the cross-section of the convex rib, the two sides of the bottom end of the convex rib are concave inward, so as to be snap-fitted with the groove 31 of the veneer plate 3 to form a bite.

[0044] In some preferred embodiments, the distance between two adjacent transverse ribs 111 is equal to the distance between two adjacent vertical ribs 112; then, with the convex rib reinforcement 113 as the center, the distance between two adjacent transverse ribs 111 is the variable side length to form a square wall panel unit; in the wall panel unit, the outer side surface of the panel 12 is concave inwardly along the y-axis direction where the transverse rib 111 is located and the z-axis direction where the vertical rib 112 is located, with the convex rib reinforcement 113 as the center. It can be understood that an inwardly concave inclined surface is formed on the outer side surface of the panel 12 with the convex rib reinforcement 113 as the center, and the inclined surface is centered on the convex rib reinforcement 113 and is symmetrically arranged along the y-axis direction and the z-axis direction; the aerogel coating 2 is sprayed on the outer side of the inner layer board 1 to form a coating of the same shape as the outer side surface of the inner layer board 1; correspondingly, the veneer 3 is cast on the outer side of the aerogel coating 2, thereby forming a groove 31 corresponding to the protrusion 121 in the middle of the veneer 3, and on the inner side surface of the veneer 3 with the groove 31 as the center along the transverse rib 1 The panel 12 and the facing panel 3 are convex in the y-axis direction and the z-axis direction of the straight line 112. It can be understood that on the inner side of the facing panel 3, with the groove 31 as the center, an outward convex inclined surface is formed around the groove 31, and the inclined surfaces around the groove 31 are centered on the groove 31 and are symmetrically arranged along the y-axis and z-axis directions, thereby forming a two-way inclined overlapping interface between the panel 12 and the facing panel 3. The design of the overlapping and biting of the interfaces realizes interlocking in the y-axis and z-axis directions. It can be understood that multiple wall panel units can form a large integrated wall panel. As far as the entire wall is concerned, the overlapping interface formed between the panel 12 and the facing panel 3 is convex and concave, and is plugged into each other, thereby ensuring the overall strength of the wall; further, in the x-axis direction, through the setting of the protrusion 121 on the panel 12 and the groove 31 of the facing panel 3, the mutual embedding between the layers of structure is realized, thereby realizing interlocking in the three directions of x-axis, y-axis and z-axis, thereby increasing the strength of the wall panel.

[0045] It should be noted that the wall panel can be divided into several wall panel units. Several wall panel units can be cast at one time to form a wall panel, or 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 spliced ​​unit (here the large unit may include 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.

[0046] Preferably, combined Figure 2As shown, the side length L of the wall panel unit is not more than 200mm, and the thickness D is not more than 60mm. The length of the wall panel unit division (i.e. the size of the unit's large surface in two directions) is the recommended spacing of the horizontal and vertical reinforcements of the skeleton, which can ensure the skeleton support and meet the wall panel load-bearing and protrusion anchoring requirements. The second is the recommended constraint range of the panel protrusion, which can ensure that the protrusion provides sufficient constraints for the aerogel layer and the veneer to avoid shear damage to the rib reinforcement. The wall panel unit thickness limit here is the result of the combined effect of the wall panel material partitioning and structural design, with the aim of achieving the performance goals of thin wall panels, large load-bearing, and strong insulation.

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

[0048] It is understandable that the protrusion has the following appearance advantages: the protrusion adopts a joint-like bone shape design, which minimizes the stress concentration phenomenon at the edges and corners while providing internal and external constraints on the wall panel plane, and can give full play to its own strength; and has the following size advantages: the height and width of the protrusion cross section are positively correlated with the thickness and width of the constraint unit test plate, respectively. Within the recommended ratio relationship range, it can ensure that the protrusion's own strength is higher than the required constraint stress. In addition, the recommended protrusion cross section can be used to set a variety of diameters of steel bars to improve the protrusion's force performance.

[0049] Further preferably, in combination Figure 5 and Figure 8 As shown, the minimum distance between the inner side surface of panel 12 and the inclined surface of panel 12 is D2, D2 = D-D1; the angle between the outer inclined surface and the inner side surface of panel 12 is θ, tan = 2(D1-D2) / L, where "equal" can also be approximately equal, 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 lateral constraint of the protrusion, and its range is determined by the limit values ​​of the wall thickness and the unit size. Because it is not the main source of lateral constraint, its most unfavorable value, i.e. 0°, is also acceptable, and no specific constraints are imposed on its range.

[0050] The embodiment of the present invention provides a wall panel with an interlocking structure, wherein the layer structure includes an inner layer panel, an aerogel coating and a veneer panel, thereby ensuring the sound insulation and heat preservation effect of the wall panel; wherein the inner layer panel includes a frame and a panel; the frame includes a plurality of transverse ribs, vertical ribs and convex rib reinforcements; a plurality of protrusions are arranged on the outer side of the panel; a plurality of grooves matching the protrusions are arranged on the inner side of the veneer panel, and a mechanical bite force is formed by the arrangement of the protrusions and the grooves; and the grooves are arranged with inclined surfaces around them, matching the inclined surfaces around the protrusions, thereby forming an inclined overlapping interlocking structure. The interface is inserted to form a resistance supplement and increase the safety redundancy of the wall panel. When the wall panel is in use, along the y-axis direction of the straight line where the horizontal reinforcement is located and the z-axis direction of the straight line where the vertical reinforcement is located, 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 x-axis direction perpendicular to both the horizontal and vertical reinforcements, the wall panel resists the out-of-plane load through the mechanical bite force of the protrusion and the friction force of the overlapping interface, thereby forming a three-way interlocking mechanism of the heterogeneous material layer, thereby ensuring the strength of the wall and preventing it from falling off.
