[0051] The exterior wall refers to the outermost part of a building that is in direct contact with the outdoor environment. Exterior walls serve functions such as building protection, regulating indoor and outdoor temperatures, waterproofing, sound insulation, and providing an aesthetically pleasing appearance. Related exterior wall structures require connecting structures to fix the wall panels to the wall body. Different exterior wall structures have different spacing between the wall panels and the wall body, resulting in insufficient versatility of the related connecting structures.

[0052] To address the technical problem that existing wall structures require connection structures to fix wall panels to the wall, and that different exterior wall structures have different spacing between wall panels and the wall, resulting in insufficient versatility of the connection structures, this application provides an indirectly fixed exterior wall structure. The wall panel assembly is fixedly connected to the wall through a fixing node. The fixing node has a height-adjustable protrusion to ensure that the wall panel assembly is flat after being fixedly connected to the wall.

[0053] Please refer to Figure 1 , Figure 1 This is a schematic diagram of an indirectly fixed exterior wall structure provided in an embodiment of this application. The exterior wall structure includes: a wall 10, a wall panel assembly 20, and a fixing node 30 for fixing the wall panel assembly 20 to the wall 10. For example, the wall panel assembly 20 is modularly designed. During the process of laying the wall panel assembly 20 on the wall 10, several wall panel assemblies 20 are laid layer by layer from bottom to top on the surface of the wall panel assembly 20, and the wall panel assembly 20 is fixed to the surface of the wall 10 by the fixing node 30 set between two adjacent wall panel assemblies 20.

[0054] Please refer to Figure 2-3 , Figure 2 and Figure 3 These are all schematic diagrams of the fixed nodes provided in the embodiments of this application.

[0055] like Figure 2 As shown, Figure 2This is a schematic diagram of a fixed node 30 provided in an embodiment of this application. The fixed node 30 includes a connecting structure 310, a first-type adapter plate 320, and a connecting plate 330. The connecting structure 310 is attached to the wall panel assembly 20. The first-type adapter plate 320 includes an adapter body 321 and a first hook structure 322, which is directly fixed to the adapter body 321. The connecting plate 330 includes a fixed plate 331 and an extension wall 332, which extends from one side of the fixed plate 331. The other side of the fixed plate 331 has a second hook structure 333, which can hook onto the first hook structure 322. During the process of laying the wall panel assembly 20 on the surface of the wall 10, the wall panel assembly 20 is first laid on the surface of the wall 10 according to its size. The installation position of the adapter plate 320 is planned, and the first type of adapter plate 320 is directly fixed on the surface of the wall 10 according to the pre-planned installation position. The wall panel components 20 are stacked from bottom to top. When the upper wall panel component 20 is installed on the lower wall panel component 20, the connecting plate 330 is engaged with the first hook structure 322 on the adapter plate 320 through the second hook structure 333, thereby connecting the connecting plate 330 to the adapter plate 320. The connecting structure 310 is connected to the fixing 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 between the upper wall 10 and the lower wall 10, and the connecting structure 310 is attached to the two adjacent walls 10, thereby completing the laying of the wall panel components 20.

[0056] like Figure 3 As shown, Figure 3 This is a schematic diagram of another optional fixed node provided in this application embodiment. In this embodiment, a second type of adapter plate 320 is also provided. The second type of adapter plate 320 further includes an adjustment protrusion 323 on the basis of the first type of adapter plate 320. The adjustment protrusion 323 protrudes from the adapter body 321. 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 is understood that during the construction process of the wall 10, errors in verticality and flatness may occur 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 verticality and flatness errors, thereby ensuring the flatness of the wall panel assembly 20 after it is laid on the surface of the wall 10.

[0057] like Figure 4As shown, in some embodiments, the second type of adapter plate 320 includes multiple subtypes, and the protrusion size of the adjustment protrusion 323 on each subtype of adapter plate 320 is different. By setting multiple types of second-type adapter plates 320 with different height adjustment protrusions 323, the fixed node 30 can be adapted to the wall 10 with different verticality and flatness errors, thereby ensuring the flatness of the wall panel assembly 20 after it is laid on the surface of the wall 10.

[0058] like Figure 4 As shown, in some embodiments, the dimensions of the adjustment protrusions 323 of each subtype of adapter plate 320 form an arithmetic sequence. During use, by adjusting the dimensions of the protrusions 323 to form an arithmetic sequence, the adapter plate 320 allows users to quickly match the required specifications through simple calculations, achieving the effects of standardization, scalability, and easy management.

[0059] like Figure 4 As shown, in some embodiments, the adjustment protrusion 323 has a hollow structure. The adjustment protrusion 323 with the hollow structure can not only achieve the weight reduction of the adapter plate 320, but also reduce the material consumption of the adapter plate 320, thereby achieving the technical effect of cost optimization.

[0060] like Figures 2-3 As shown, in some embodiments, there are multiple first hook structures 322, and the opening directions of each first hook structure 322 are the same. For example, in this embodiment, multiple first hook structures 322 are provided on the adapter plate 320, and the multiple first hook structures 322 are arranged sequentially along the opening direction of the first hook structures 322. The connecting plate 330 is provided with multiple second hook structures 333 that are opposite to the first hook structures 322 in terms of snapping. In use, the adapter plate 320 is fixedly installed on the surface of the wall 10. When the wall panel assembly 20 is fixed to the wall 10, it can be directly snapped with the first hook structures 322 on the adapter plate 320 through the second hook structures 333 on the connecting plate 330, so that the wall panel assembly 20 can be stably fixed to the wall 10.

[0061] In some embodiments, the distance between two adjacent first hook structures 322 is greater than the vertical dimension of the second hook structure 333, so as to facilitate the connection between the first hook structure 322 and the second hook structure 333. It can be understood that, in this embodiment, the side with the opening of the first hook structure 322 and the second hook structure 333 can be defined as the top end, and the side of the first hook structure 322 and the second hook structure 333 away from the opening can be defined as the bottom end. Therefore, the distance between two adjacent first hook structures 322 can be understood as the distance between the bottom end of the upper first hook structure 322 and the top end of the lower first hook structure 322. The vertical dimension of the second hook structure 333 can be understood as the distance between the top end and the bottom end of the same second hook structure 333. Therefore, in this embodiment, the distance between two adjacent first hook structures 322 is greater than the vertical dimension of the second hook structure 333, which facilitates the connection between the first hook structure 322 and the second hook structure 333.

[0062] like Figure 5 As shown, Figure 3 This is a schematic diagram of another optional fixed node provided in this embodiment. In this embodiment, the openings of adjacent first hook structures 322 are set. For example, in this embodiment, the adapter plate 320 is provided with multiple first hook structures 322, and the openings of two adjacent first hook structures 322 are set opposite to each other. When the connecting plate 330 is installed on the adapter plate 320, the second hook on the connecting plate 330 can be snapped between two adjacent first hook structures 322 by lateral snapping.

[0063] In some embodiments, such as Figure 6 As shown, the fixed node 30 also includes a hook pad 340, which is located between the top of the first hook structure 322 and the second hook structure 333. For example, when the first hook structure 322 and the second hook structure 333 are connected and a gap appears between them, the hook pad 340 is placed in the gap between them to compensate for the gap. Understandably, during construction, the adapter plate 320 needs to be fixed to the surface of the wall 10 first, and then the wall panel assembly 20 is laid on the wall 10 sequentially through the connecting plate 330. However, during this process, due to possible errors in the installation position of the adapter plate 320, the first hook structure 322 and the second hook structure 333 cannot fully cooperate when the connecting plate 330 is connected to the adapter plate 320, resulting in a gap. Therefore, in this embodiment, a hook pad 340 is installed at the gap between the first hook structure 322 and the second hook structure 333 to increase the stability of the connection between the connecting plate 330 and the adapter plate 320.

[0064] like Figure 7 As shown, Figure 7 This is a transverse sectional view of the hook pad provided in this embodiment; in this embodiment, the hook pad 340 has a wedge-shaped structure. It can be understood that one end of the hook pad 340 has a bevel, which allows the hook pad 340 to be inserted more easily into the gap between the first hook structure 322 and the second hook structure 333, thereby filling the gap between the first hook structure 322 and the second hook structure 333.

[0065] For example, in this embodiment, multiple hook pads 340 can be provided. The inclined surfaces at the ends of the multiple hook pads 340 can be provided with different inclination angles. By using multiple different hook pads 340, different sizes of gaps can be accommodated.

[0066] In some embodiments, the hook pad 340 is made of hard rubber material. Hard rubber, also known as rigid rubber or hard rubber, is a sulfur-containing vulcanized rubber. This material is typically made from natural rubber or synthetic rubber with an unsaturated structure through 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. Furthermore, during the preparation of hard rubber, the degree of vulcanization can be controlled to maintain a certain degree of elasticity. Therefore, in this embodiment, by controlling the degree of vulcanization, a hard rubber hook pad 340 with a certain degree of elasticity is produced. This ensures its mechanical strength while allowing the hook pad 340 to be inserted more easily into the gap between the first hook structure 322 and the second hook structure 333.

[0067] In some embodiments, such as Figure 6 As shown, the connecting part of the first hook structure 322 and the second hook structure 333 is also provided with a snap-fit ​​screw 350. The snap-fit ​​screw 350 passes through the connecting plate 330, the first hook structure 322 and the second hook structure 333 in sequence, and engages with the adapter plate 320, the first hook structure 322 and the second hook structure 333. This can effectively prevent the wall panel assembly 20 from moving or the first hook structure 322 and the second hook structure 333 from slipping during use, thereby further increasing the stability of the connection between the first hook structure 322 and the second hook structure 333.

[0068] For example, in this embodiment, the snap-fit ​​screw 350 can be a self-tapping screw. During use, the snap-fit ​​screw 350 is driven into the adapter plate 320, the first hook structure 322, and the second hook structure 333 sequentially from the side of the connecting plate 330 away from the wall 10 toward the wall 10, so that the first hook structure 322 and the second hook structure 333 can be tightly connected. Secondly, since the snap-fit ​​screw 350 is driven into the adapter plate 320, the first hook structure 322, and the second hook structure 333 sequentially by self-tapping, the snap-fit ​​screw 350 can be tightly connected with the adapter plate 320, the first hook structure 322, and the second hook structure 333 without gaps, further increasing the stability of the connection between the first hook structure 322 and the second hook structure 333.

[0069] like Figure 1 As shown, in this embodiment, the fixed node 30 further includes an anchor bolt 360. The adapter body 321 is fixed to the wall 10 via the anchor bolt 360, and the anchor bolt 360 transmits the load, thereby ensuring the safety and stability of the adapter body 321. For example, the anchor bolt 360 can be a chemical bolt, mechanical bolt, adhesive bolt, threaded bolt, wire rope bolt, or anchor bolt. The type of anchor bolt 360 can be selected according to actual needs during use.

[0070] In some embodiments, there are multiple anchor bolts 360, and the multiple anchor bolts 360 are located on both sides of the first hook structure 322 in the vertical direction. It is understood that multiple anchor bolts 360 can also be provided on the adapter body 321. The multiple anchor bolts 360 are respectively distributed at the upper end and the lower end of the adapter body 321. Providing multiple anchor bolts 360 on the adapter body 321 can further increase the stability of the adapter body 321 when it is installed on the surface of the wall 10.

[0071] In this embodiment, the connecting plates 330 are of different types, and the extension walls 332 of each type of connecting plate 330 have different dimensions. By using multiple connecting plates 330 of different lengths, not only can wall panel assemblies 20 of different thicknesses be laid on the surface of the wall 10, but they can also be matched with the first type of adapter plate 320 or the second type of adapter plate 320. While being able to adapt to walls 10 with different verticality and flatness errors, by selecting a suitable combination, the stability of the wall panel assembly 20 after being laid on the surface of the wall 10 can be guaranteed.

[0072] In some embodiments, the dimensions of the extension walls 332 of the various types of connecting plates 330 form an arithmetic sequence. During use, the connecting plates 330 with the dimensions of the extension walls 332 forming an arithmetic sequence allow users to quickly match the required specifications through simple calculations, achieving standardization, scalability, and ease of management.

[0073] In some embodiments, such as Figure 8 As shown, the connecting plate 330 also includes a marking protrusion 370, which protrudes from the outer surface of the extension wall 332. The number of marking protrusions 370 is positively correlated with the size of the extension wall 332. The size of the extension wall 332 of the connecting plate 330 can be quickly identified by the marking protrusions 370, so that the user can select the connecting plate 330 of the required specifications.

[0074] In some embodiments, such as Figure 8 As shown, the marking protrusion 370 protrudes from the extension wall 332 by less than 0.5 mm, ensuring that the marking protrusion 370 is clearly visible while avoiding the marking protrusion 370 affecting the connection between the extension wall 332 and the connection structure 310.

[0075] like Figure 1 As shown, the wall panel assembly 20 includes a wall panel 21, a filling layer 22, and positioning screws 23. The filling layer 22 is fixed to the side of the wall panel 21 near the wall 10. The extension wall 332 is connected to the filling layer 22 by the positioning screws 23, so that the connecting plate 330 can be connected to the wall panel assembly 20 by the positioning screws 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, waterproofing and moisture-proofing, or sound insulation and noise reduction. 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.

[0076] Secondly, in this embodiment, as 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 a decorative and aesthetic purpose but also protects the filling layer 22. Exemplarily, in this embodiment, in addition to the above functions, the wall panel 21 can also achieve different functions depending on the material used, such as thermal insulation material, waterproof material, or sound insulation material, thereby enabling the wall panel 21 to achieve functions such as thermal insulation, waterproofing, moisture resistance, or sound insulation.

[0077] In some embodiments, such as Figure 8As 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 connects 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. This can prevent 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, which would affect the stability of the wall panel assembly 20 when it is laid on the surface of the wall 10.

[0078] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
