[0029] The outer wall refers to the part located at the outermost side of the building and directly contacting with the outdoor environment. The outer wall can realize building protection, indoor and outdoor temperature adjustment, waterproofing, sound insulation and provide an attractive appearance, etc. In the related outer wall structure, the wall panel and the wall body are fixedly connected through a connecting structure. The wall panel and the wall body have different spacings in different outer wall structures, resulting in insufficient universality of the related connecting structure.

[0030] In order to solve the technical problem that in the existing wall structure, the wall panel and the wall body are fixedly connected through a connecting structure, the wall panel and the wall body have different spacings in different outer wall structures, resulting in insufficient universality of the related connecting structure, the present application provides an indirectly fixed outer wall structure. The wall panel assembly is fixedly connected to the wall body through a fixing node. The fixing node has a height adjusting protrusion, so that after the wall panel assembly is fixedly connected to the wall body, the wall panel assembly can be ensured to be flat.

[0031] Please refer to Figure 1 , Figure 1A structure diagram of an indirectly fixed outer wall structure is provided in the embodiments of the present application, and the outer wall structure comprises a wall body 10, a wall plate assembly 20, and a fixing node 30 for fixedly connecting the wall plate assembly 20 and the wall body 10. The wall plate assembly 20 is designed in a modular manner. During the laying of the wall plate assembly 20 on the wall body 10, a plurality of wall plate assemblies 20 are laid on the surface of the wall plate assembly 20 one by one from bottom to top, and the wall plate assembly 20 is fixed to the surface of the wall body 10 through the fixing node 30 arranged between the upper and lower adjacent wall plate assemblies 20.

[0032] Please refer to Figures 2-3 , Figure 2 and Figure 3 are structure diagrams of the fixing node provided in the embodiments of the present application.

[0033] As shown in Figure 2 , Figure 2 is a structure diagram of a fixing node 30 provided in the embodiments of the present application. The fixing node 30 comprises a connecting structure 310, a first type of adapter plate 320, and a connecting plate 330. The connecting structure 310 is attached to the wall plate assembly 20. The first type of adapter plate 320 comprises an adapter body 321 and a first hooking structure 322. The first hooking structure 322 is directly fixed to the adapter body 321. The connecting plate 330 comprises a fixed plate 331 and an extension wall 332. The extension wall 332 extends from one side of the fixed plate 331. The other side of the fixed plate 331 has a second hooking structure 333. The second hooking structure 333 can be hooked to the first hooking structure 322. During the laying of the wall plate assembly 20 on the surface of the wall body 10, the installation position of the adapter plate 320 is planned on the surface of the wall body 10 according to the size of the wall plate assembly 20. The first type of adapter plate 320 is directly fixed and installed on the surface of the wall body 10 according to the pre-planned installation position. The wall plate assemblies 20 are stacked one by one from bottom to top. When the upper wall plate assembly 20 is installed on the lower wall plate assembly 20, the connecting plate 330 is connected to the adapter plate 320 through the second hooking structure 333 and the first hooking structure 322 on the adapter plate 320. The connecting structure 310 is connected to the fixed plate 331 of the connecting plate 330 through the extension wall 332 on the connecting plate 330. The connecting structure 310 is placed at the joint of the upper wall body 10 and the lower wall body 10, and is attached to the two adjacent wall bodies 10. Thus, the laying of the wall plate assembly 20 is completed.

[0034] As shown in Figure 3 , Figure 3A structural schematic diagram of another optional fixed node provided for an embodiment of the present application, in this embodiment, a second type of adapter plate 320 is further provided, and the second type of adapter plate 320 further includes an adjustment protrusion 323 on the basis of the first type of adapter plate 320, and the adjustment protrusion 323 protrudes from the adapter body 321, and the first hook structure 322 of the second type of adapter plate 320 is fixed to the adapter body 321 through the adjustment protrusion 323. It can be understood that during the construction process of the wall 10, the verticality and flatness of the wall 10 may have errors due to factors such as design, construction, materials or environment. In this embodiment, the adjustment protrusion 323 on the second type of adapter plate 320 can compensate for the tilt of the wall 10 caused by the verticality and flatness errors, thereby ensuring the flatness of the wall panel assembly 20 after being laid on the surface of the wall 10.

[0035] like Figure 4 As shown, in some embodiments, the second type of adapter plate 320 includes multiple subtypes, and the protruding sizes of the adjustment protrusions 323 on each subtype of the adapter plate 320 are different. By setting the second type of adapter plate 320 with multiple adjustment protrusions 323 of different heights, the fixed node 30 can adapt to the wall 10 with different verticality and flatness errors, thereby ensuring the flatness of the wall panel assembly 20 after being laid on the surface of the wall 10.

[0036] like Figure 4 As shown, in some embodiments, the sizes of the adjustment protrusions 323 of each sub-type of adapter plates 320 form an arithmetic progression. During use, the adapter plates 320 of the arithmetic progression are formed by adjusting the sizes of the protrusions 323, so that users can quickly match the required specifications through simple calculations, thereby achieving standardized, scalable and easy-to-manage effects.

[0037] like Figure 4 As shown, in some embodiments, the adjustment protrusion 323 has a hollow structure. The hollow structure of the adjustment protrusion 323 can not only achieve lightweighting of the adapter plate 320, but also reduce the material consumption of the adapter plate 320, thereby achieving a technical effect of cost optimization.

[0038] like Figures 2-3As shown, in some embodiments, the number of the first hooking structures 322 is multiple, and the opening directions of each first hooking structure 322 are the same. For example, in the present embodiment, a plurality of first hooking structures 322 are arranged on the adapter plate 320, and the plurality of first hooking structures 322 are sequentially arranged along the opening direction of the first hooking structure 322. A plurality of second hooking structures 333 opposite to the first hooking structures 322 are arranged on the connecting plate 330. In use, the adapter plate 320 is fixedly arranged on the surface of the wall body 10, and when the wallboard assembly 20 is fixed on the wall body 10, the second hooking structures 333 on the connecting plate 330 can be directly connected with the first hooking structures 322 on the adapter plate 320, so that the wallboard assembly 20 can be stably fixed on the wall body 10.

[0039] In some embodiments, the distance between two adjacent first hooking structures 322 is greater than the vertical dimension of the second hooking structure 333, so as to facilitate the connection between the first hooking structure 322 and the second hooking structure 333. It can be understood that in the present embodiment, the side of the first hooking structure 322 and the second hooking structure 333 opening can be defined as the top end, and the side of the first hooking structure 322 and the second hooking structure 333 away from the opening can be defined as the bottom end. Therefore, the distance between two adjacent first hooking structures 322 can be understood as the distance between the bottom end of the upper first hooking structure 322 and the top end of the lower first hooking structure 322, and the vertical dimension of the second hooking structure 333 can be understood as the distance between the top end and the bottom end of the same second hooking structure 333. Therefore, in the present embodiment, the distance between two adjacent first hooking structures 322 is greater than the vertical dimension of the second hooking structure 333, which facilitates the connection between the first hooking structure 322 and the second hooking structure 333.

[0040] As shown, Figure 5 As shown, Figure 3 Another alternative structure of the fixing node provided in the present embodiment is shown in the structure diagram. In the present embodiment, the openings of adjacent first hooking structures 322 are arranged opposite to each other. For example, in the present embodiment, a plurality of first hooking structures 322 are arranged on the adapter plate 320, and the openings of two adjacent first hooking structures 322 are arranged opposite to each other. When the connecting plate 330 is installed on the adapter plate 320, the second hooking structure 333 on the connecting plate 330 can be laterally buckled and connected between the two adjacent first hooking structures 322.

[0041] In some embodiments, as Figure 6As shown, the fixed node 30 further comprises a hooking pad 340, which is located between the top of the first hooking structure 322 and the second hooking structure 333. When the first hooking structure 322 and the second hooking structure 333 are connected, and a gap appears between the first hooking structure 322 and the second hooking structure 333, the hooking pad 340 is placed in the gap between the first hooking structure 322 and the second hooking structure 333 to compensate for the gap between the first hooking structure 322 and the second hooking structure 333. It can be understood that during construction, the adapter plate 320 needs to be fixed on the surface of the wall 10 first, and then the wallboard assembly 20 is laid on the wall 10 in sequence through the connecting plate 330. During this process, due to the installation position error of the adapter plate 320, the first hooking structure 322 and the second hooking structure 333 cannot be completely matched when the connecting plate 330 is connected with the adapter plate 320, and a gap will appear. Therefore, in this embodiment, the hooking pad 340 is installed in the gap between the first hooking structure 322 and the second hooking structure 333 to increase the stability of the connecting plate 330 when connected with the adapter plate 320.

[0042] As shown, Figure 7 Figure 7 The transverse sectional view of the hooking pad provided in this embodiment; in this embodiment, the hooking pad 340 is a wedge-shaped structure. It can be understood that the end of the hooking pad 340 is provided with an inclined surface, which can make the hooking pad 340 more easily inserted into the gap between the first hooking structure 322 and the second hooking structure 333, and then fill the gap between the first hooking structure 322 and the second hooking structure 333.

[0043] For example, in this embodiment, a plurality of hooking pads 340 can be provided, and the inclined surfaces at the ends of the plurality of hooking pads 340 can be provided with inclined surfaces with different inclination angles. Through the plurality of different hooking pads 340, different gap requirements can be adapted.

[0044] ​In some embodiments, the hooking gasket 340 is made of hard rubber material. It can be understood that hard rubber is also known as hard rubber or hard rubber, which is a vulcanized rubber containing sulfur. This material is usually made of natural rubber or synthetic rubber with unsaturated structure by sulfur vulcanization. Hard rubber is generally dark brown, hard in texture, and has high mechanical strength. It has low water absorption and thermal conductivity, as well as good electrical insulation, aging resistance and chemical corrosion resistance. Secondly, during the preparation of hard rubber, the degree of vulcanization of the rubber can be controlled to retain a certain elasticity. Therefore, in this embodiment, the hard rubber hooking gasket 340 with a certain elasticity is made by controlling the degree of vulcanization, which can make the hooking gasket 340 more easily inserted into the gap between the first hooking structure 322 and the second hooking structure 333 while ensuring the mechanical strength.

[0045] In some embodiments, as shown in Figure 6 The connecting portion of the first hooking structure 322 and the second hooking structure 333 is also provided with a clamping screw 350, which passes through the connecting plate 330, the first hooking structure 322 and the second hooking structure 333 in sequence and engages with the adapter plate 320, the first hooking structure 322 and the second hooking structure 333. It can effectively prevent the wallboard assembly 20 from moving or the first hooking structure 322 and the second hooking structure 333 from slipping during use, thereby further increasing the stability of the connection between the first hooking structure 322 and the second hooking structure 333.

[0046] Exemplarily, in this embodiment, the clamping screw 350 can be selected from a tapping bolt. During use, the clamping screw 350 is tapped into the adapter plate 320, the first hooking structure 322 and the second hooking structure 333 in sequence from the side of the connecting plate 330 away from the wall 10 to the wall 10, and the first hooking structure 322 and the second hooking structure 333 can be tightly connected. Secondly, since the clamping screw 350 is tapped into the adapter plate 320, the first hooking structure 322 and the second hooking structure 333 in sequence by self-tapping, the clamping screw 350 and the adapter plate 320, the first hooking structure 322 and the second hooking structure 333 can be tightly connected, without gaps, further increasing the stability of the connection between the first hooking structure 322 and the second hooking structure 333.

[0047] As shown in Figure 1As shown, in the embodiment, the fixed node 30 further comprises an anchor 360, the adapter body 321 is fixed to the wall 10 through the anchor 360, the adapter body 321 is fixed to the surface of the wall 10 through the anchor 360, and the load is transmitted through the anchor 360, so as to ensure the safety and stability of the adapter body 321. For example, the anchor 360 can be a chemical bolt, a mechanical bolt, an adhesive bolt, a screw bolt, a wire bolt or a foundation bolt, and the type of the anchor 360 can be selected according to actual needs during use.

[0048] In some embodiments, the anchor 360 has a plurality of anchors 360 located on both sides of the first hooking structure 322 in the vertical direction. It can be understood that a plurality of anchors 360 can also be arranged on the adapter body 321, and the plurality of anchors 360 are respectively distributed on the upper end and the lower end of the adapter body 321. Arranging a plurality of anchors 360 on the adapter body 321 can further increase the stability of the adapter body 321 when installed on the surface of the wall 10.

[0049] In the embodiment, the connecting plate 330 has different types, and the extension wall 332 of each type of connecting plate 330 has different sizes. By using a plurality of connecting plates 330 with different lengths, the surface of the wall 10 can be paved with wall panel assemblies 20 of different thicknesses, and the first type of adapter plate 320 or the second type of adapter plate 320 can be matched with each other. In this way, the wall 10 with different verticality and flatness errors can be adapted, and the stability of the wall panel assembly 20 after being paved on the surface of the wall 10 can be ensured by selecting a suitable combination.

[0050] In some embodiments, the sizes of the extension walls 332 of the connecting plates 330 of different types form an arithmetic sequence. In use, by using the connecting plates 330 with the extension walls 332 of the sizes forming an arithmetic sequence, the user can quickly match the required specifications by simple calculation, achieving the effects of standardization, scalability and easy management.

[0051] In some embodiments, as shown in Figure 8 As shown, the connecting plate 330 further comprises a marking protrusion 370 protruding from the outer surface of the extension wall 332. The number of the marking protrusions 370 is in a positive correlation with the size of the extension wall 332. The marking protrusions 370 can quickly identify the size of the extension wall 332 of the connecting plate 330, so that the user can select the connecting plate 330 of the required specification.

[0052] In some embodiments, as shown in Figure 8 As shown, the size of the marking protrusion 370 protruding from the extension wall 332 is less than 0.5 mm. In this way, the marking protrusion 370 is clearly visible, and the connection between the extension wall 332 and the connecting structure 310 is not affected.

[0053] like Figure 1 As shown, the wall panel assembly 20 includes a wall panel 21, a filling layer 22 and a positioning screw 23. The filling layer 22 is fixed to the side of the wall panel 21 close to the wall 10, and the extension wall 332 is connected to the filling layer 22 by the positioning screw 23, so that the connecting plate 330 can be connected to the wall panel assembly 20 by the positioning screw 23. It can be understood that in this embodiment, the filling layer 22 can be set as a functional wall on the surface of the wall 10 to enhance the practicality of the wall panel assembly 20. For example, different functions can be achieved according to the material of the filling layer 22, such as thermal insulation material, waterproof material or sound insulation material, so that the filling layer 22 can achieve functions such as thermal insulation, waterproof and moisture-proof or sound insulation and silencing. Therefore, in this embodiment, the filling layer 22 made of different functional materials can be selected according to actual needs to increase the practicality of the wall panel assembly 20 laid on the surface of the wall 10.

[0054] Secondly, in this embodiment, if Figure 1 As shown, the wall panel 21 is disposed on the side of the filling layer 22 away from the wall 10, which not only serves as a decorative aesthetic, but also protects the filling layer 22. For example, in this embodiment, in addition to the above functions, the wall panel 21 can also be made of different materials to achieve different functions, such as thermal insulation, waterproofing, or sound insulation, thereby enabling the wall panel 21 to also achieve functions such as thermal insulation, waterproofing, moisture-proofing, or sound insulation.

[0055] In some embodiments, as Figure 8 As shown, the extension wall 332 has a positioning hole 334, and the head of the positioning screw 23 is accommodated in the positioning hole 334. It can be understood that after the positioning screw 23 passes through the extension wall and is connected to the wall panel assembly 20, the head of the positioning screw 23 is accommodated in the positioning hole 334, that is, the head of the positioning screw 23 does not protrude or only partially protrudes from the extension wall, thereby preventing the head of the positioning screw 23 from contacting the bottom of the upper wall 10 when the upper wall 10 is connected to the lower wall 10, so that a gap is formed between the upper wall 10 and the extension wall, affecting the stability of the wall panel assembly 20 when it is laid on the surface of the wall 10.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
