Description

Technical Field

[0001] This invention relates to the field of wall decoration technology, and in particular to a dry-hanging curtain wall system and construction method. Background Technology

[0002] Dry-hanging curtain wall systems are exterior wall decoration systems that fix decorative panels to the building's wall frame using metal hangers. They are widely used in exterior wall decoration projects for high-rise buildings, commercial complexes, and other similar projects. Compared to traditional wet-laying methods, dry-hanging does not use cement mortar for bonding. The hangers and frame system bear the weight of the panels and external loads, offering advantages such as convenient construction, prevention of efflorescence, and ease of maintenance and replacement. In existing dry-hanging curtain wall systems, tiles typically use back-bolt or back-groove hangers, which are fixed to the back of the tiles before being hung onto the frame.

[0003] Existing dry-hanging curtain wall systems typically employ a bidirectional keel structure, with vertical main keels fixed to the building wall and horizontal secondary keels connected to them. Tile hangers are attached to these secondary keels. Each tile is independently attached to the secondary keel via two or four hanging points, with tiles flexibly connected only by joint sealant; there is no mechanical transfer between adjacent tiles. In this structure, the out-of-plane load (such as wind load) of each tile is borne independently by its own hanging nodes, and the load-bearing capacity of these nodes determines the maximum dimensions of a single tile.

[0004] However, existing technologies have the following shortcomings: On the one hand, the transverse secondary keel in the longitudinal and transverse bidirectional keel structure requires a large amount of material and involves many installation procedures, which increases material costs and construction time; on the other hand, each tile bears its own load, and the out-of-plane load cannot be distributed between the tiles, resulting in concentrated stress at the hanging nodes. In the exterior walls of high-rise buildings with large wind loads, the hanging nodes of a single tile need to withstand large out-of-plane forces, which requires high strength of the hangers and stiffness of the keel, limiting the increase in the size of a single tile and the improvement of the overall economy of the curtain wall system. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a dry-hanging curtain wall system and construction method, which solves the technical problem that there is no mechanical transfer relationship between adjacent tiles in the prior art, and the out-of-plane load is borne independently by a single hanging node and cannot be diffused, resulting in the concentration of force at the hanging node.

The tenon and the insertion groove are inserted and fitted in the vertical direction, and the lower surface of the tenon and the lower surface of the insertion groove are in close contact with zero gap. A horizontal micro-sliding gap is reserved between the side mating surfaces of the tenon and the insertion groove.

[0011] Optionally, the horizontal connecting assembly includes a second connecting plate and a locking plate; the second connecting plate is fixed to the back of the left and right edges of the tile body, and the locking plate extends upward perpendicular to the second connecting plate; the end of the locking plate located on the left edge of the tile is provided with an outwardly protruding tenon, and the end of the locking plate located on the right edge of the tile is provided with an inwardly recessed groove, and the tenon and the groove are engaged in the horizontal direction.

[0012] Optionally, the mounting node includes a mounting groove and a spring locking element; the mounting groove is provided on the keel mounting frame and has an L-shaped cross-section, the mounting groove has a vertical part and a horizontal part, the top of the vertical part forms an opening, and the spring locking element is provided on the horizontal part; at least four ceramic tile bodies in the brick group bearing module are provided with mounting rods on their backs, the mounting rods enter the vertical part through the opening, enter the horizontal part through the vertical part and abut against the spring locking element, so that the spring locking element elastically deforms and reaches the installation position, and the spring locking element returns to its original position to lock the mounting rod in the installation position.

[0013] Optionally, the spring locking element is a spring ball, which includes a ball and a spring. The horizontal part of the wall has a mounting hole, the spring is set in the mounting hole, and the ball part extends out of the mounting hole. The spring pre-tightens the ball towards the inside of the hook groove. When the hook rod passes through, it pushes the ball to compress the spring and retract into the mounting hole.

[0022] (III) Beneficial Effects

[0023] The beneficial effects of this invention are:

[0024] This invention provides a dry-hanging curtain wall system. By setting interlocking connection components, including vertical and horizontal connection components, on the back of the ceramic tile body, adjacent ceramic tile units are connected in both vertical and horizontal directions. After multiple ceramic tile bodies are connected to form a brick group load-bearing module, they are installed on the keel mounting frame through hanging nodes. The vertical connection components establish a force transmission path between adjacent ceramic tile units in the vertical direction, and the horizontal connection components establish a force transmission path between adjacent ceramic tile units in the horizontal direction. This creates a two-dimensional continuous force transmission network inside the brick group load-bearing module. When an out-of-plane load acts on a single ceramic tile body, it is diffused within the brick group load-bearing module through the interlocking connection components and shared by multiple hanging nodes, reducing the stress concentration of a single hanging node. At the same time, the integrity of the brick group load-bearing module means that the keel mounting frame does not need to be equipped with horizontal keels to meet the load-bearing requirements of the out-of-plane load, reducing the amount of keel material and installation procedures. Compared with the prior art, this system establishes a mechanical transmission relationship between ceramic tile units through interlocking connection components, realizing the diffusion and sharing of out-of-plane loads within the brick group load-bearing module, thereby ensuring the load-bearing capacity of the curtain wall system even without horizontal keels.

[0037] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0038] Example 1:

[0039] like Figure 1 and Figure 3As shown, this embodiment provides a dry-hanging curtain wall system, including a keel mounting frame 1, multiple tile units 2, and multiple hanging nodes 3; the keel mounting frame 1 is arranged on the side of the building wall 5; the tile unit 2 includes a tile body 21 and an interlocking connection component disposed on the back of the tile body 21, the interlocking connection component includes a vertical connection component 22 and a horizontal connection component 23, the vertical connection component 22 is disposed on the upper and lower edges of the tile body 21, and is used to connect with the vertical connection component 22 of the adjacent tile unit 2 in the vertical direction, the horizontal connection component 23 is disposed on the left and right edges of the tile body 21, and is used to connect with the horizontal connection component 23 of the adjacent tile unit 2 in the horizontal direction; multiple tile bodies 21 are connected to form a brick group bearing module 4, and the brick group bearing module 4 is installed on the keel mounting frame 1 through multiple hanging nodes 3.

[0040] Specifically, by setting an interlocking connection component including a vertical connection component 22 and a horizontal connection component 23 on the back of the tile body 21, adjacent tile units 2 are connected in both the vertical and horizontal directions. After multiple tile bodies 21 are connected to form a brick group load-bearing module 4, they are installed on the keel mounting frame 1 through the hanging node 3. The vertical connection component 22 establishes a force transmission path between adjacent tile units 2 in the vertical direction, and the horizontal connection component 23 establishes a force transmission path between adjacent tile units 2 in the horizontal direction. This makes a two-dimensional continuous force transmission network formed inside the brick group load-bearing module 4, so that out-of-plane loads act on a single tile unit 2. When the tile body 21 is in place, it diffuses within the brick group load-bearing module 4 through interlocking connection components, and is shared by multiple hanging nodes 3, reducing the stress concentration of a single hanging node 3. At the same time, the integrity of the brick group load-bearing module 4 allows the keel mounting frame 1 to meet the load-bearing requirements of out-of-plane loads without the need for horizontal keels, reducing the amount of keel material and installation procedures. Compared with the existing technology, it forms a mechanical transmission relationship between the tile units 2 through interlocking connection components, realizing the diffusion and sharing of out-of-plane loads within the brick group load-bearing module 4, thereby ensuring the load-bearing capacity of the curtain wall system under the condition of eliminating horizontal keels.

[0041] Furthermore, such as Figure 4 and Figure 5 As shown, the vertical connecting assembly 22 includes a first connecting plate 221 and an interlocking plate 222; the first connecting plate 221 is fixed to the back of the upper and lower edges of the tile body 21, and the interlocking plate 222 extends upward perpendicularly to the first connecting plate 221; the end of the interlocking plate 222 located at the upper edge of the tile body 21 is provided with an upward-facing tenon 223, and the end of the interlocking plate 222 located at the lower edge of the tile body 21 is provided with a downward-facing insertion groove 224. The tenon 223 and the insertion groove 224 are inserted and fitted in the vertical direction, and the lower surface of the tenon 223 and the lower surface of the insertion groove 224 are tightly fitted with zero gap. A horizontal micro-sliding gap is reserved between the side mating surfaces of the tenon 223 and the insertion groove 224.

[0042] Specifically, the first connecting plate 221 is an aluminum alloy sheet with a thickness of 1.5 to 2 mm and a width of 15 to 25 mm. It is bonded to the back of the upper and lower edges of the tile body 21 using epoxy structural adhesive. Before bonding, the back of the tile body 21 is roughened by sanding to ensure bonding strength. The interlocking plate 222 is perpendicular to the first connecting plate 221. The tenon 223 and the slot 224 have rectangular cross-sectional shapes. The tenon 223 has a width of 3 to 6 mm and a height of 5 to 10 mm. The slot width and depth of the slot 224 match the tenon 223. The lower surface of the tenon 223 and the lower surface of the slot 224 fit together with zero clearance, forming a vertical load-bearing surface. Vertical loads and out-of-plane loads are transferred between adjacent tile units 2 through this load-bearing surface. A horizontal micro-slip gap of 0.2 to 0.5 mm is reserved between the mating surfaces of the tenon 223 and the slot 224. This gap allows for slight horizontal relative displacement of adjacent tile units 2 during temperature changes, preventing additional stress from being generated in the interlocking connection assembly due to thermal expansion and contraction. Simultaneously, this gap is smaller than the width of the tenon 223, ensuring a tight fit of the load-bearing surfaces in the vertical direction. For the thermal expansion and contraction of adjacent tile bodies 21 in the horizontal direction, the engagement of the tenon 233 and the slot 234 allows for slight horizontal relative displacement between adjacent tile bodies 21 within the elastic deformation range of the tenon 233, providing deformation absorption capacity. Furthermore, a 2 to 4 mm tile joint is left between adjacent tile bodies 21, filled with weather-resistant silicone sealant. The elastic modulus of the weather-resistant silicone sealant is much lower than that of the interlocking connection assembly. During thermal expansion and contraction, the sealant in the tile joint preferentially absorbs the displacement through elastic deformation, preventing additional stress from being transmitted to the interlocking connection assembly. At the edge of the brick support module 4, the width of the brick joint is appropriately increased to 3 to 5 mm to provide a margin for the overall thermal expansion of the brick support module 4.

[0043] Furthermore, such as Figure 4 and Figure 5 As shown, the horizontal connecting assembly 23 includes a second connecting plate 231 and a locking plate 232; the second connecting plate 231 is fixed to the back of the left and right edges of the tile body 21, and the locking plate 232 extends upward perpendicular to the second connecting plate 231; the end of the locking plate 232 located on the left edge of the tile body 21 is provided with a tenon 233 protruding outward, and the end of the locking plate 232 located on the right edge of the tile body 21 is provided with a groove 234 recessed inward, and the tenon 233 and the groove 234 are engaged in the horizontal direction.

[0044] Specifically, the second connecting plate 231 is an aluminum alloy sheet with a thickness of 1.5 to 2 mm and a width of 15 to 25 mm. It is bonded and fixed to the back of the left and right edges of the tile body 21 with epoxy structural adhesive. The locking plate 232 is perpendicular to the second connecting plate 231 and is integrally formed by bending the edge of the second connecting plate 231. The tenon 233 is made of spring steel or elastic stainless steel and has a one-way elastic locking characteristic. Under the action of normal pull force, it elastically deforms and disengages along the predetermined bending direction. Under the action of reverse wind suction force, it is pressed into the groove 234 to form a self-locking mechanism. The disengagement force threshold of the tenon 233 is higher than the out-of-plane load corresponding to the maximum designed wind suction force and lower than the normal pull force that can be applied by a single person using the suction cup. This ensures that the tenon 233 will not accidentally disengage under normal wind load. When it is necessary to replace a single tile, the tenon 233 can be disengaged by normal pull of the suction cup. The engagement of the tenon 233 and the slot 234 enables the left and right adjacent tile units 2 to form a horizontal connection, and the out-of-plane load is transmitted between the left and right adjacent tile units 2 through the engagement surface.

[0045] like Figure 2 As shown, the hanging node 3 includes a hanging groove 31 and a spring locking member 32; the hanging groove 31 is provided on the keel mounting frame 1 and has an L-shaped cross section. The hanging groove 31 has a vertical part 311 and a horizontal part 312. The top of the vertical part 311 forms an opening, and the spring locking member 32 is provided on the horizontal part 312; at least four ceramic tile bodies 21 in the brick group bearing module 4 are provided with hanging rods 41 on their backs. The hanging rods 41 enter the vertical part 311 through the opening, enter the horizontal part 312 through the vertical part 311 and abut against the spring locking member 32, so that the spring locking member 32 elastically deforms and reaches the installation position. The spring locking member 32 returns to its original position and locks the hanging rods 41 in the installation position.

[0046] Specifically, the mounting groove 31 is made of aluminum alloy profile with an L-shaped cross-section. The vertical part 311 extends vertically with a height of 20 to 30 mm and a width of 12 to 15 mm. The horizontal part 312 extends horizontally from the bottom end of the vertical part 311 with a depth of 25 to 35 mm and a width consistent with the vertical part 311. An opening is formed at the top of the vertical part 311, with the width of the opening consistent with the width of the vertical part 311. The mounting groove 31 is fixed to the vertical main keel 11 by bolts or welding. When fixing, ensure that the vertical part 311 is vertical, the horizontal part 312 is horizontal, and the opening faces upward.

[0047] In this embodiment, the hanging rod 41 is a cylindrical rod with a diameter of 8 to 10 mm and a length of 15 to 20 mm. One end of the hanging rod 41 is fixed to the middle of the back of the tile body 21, and the other end is a free end. The hanging rod 41 is fixed to the back of the tile body 21 by a back bolt anchoring method: a conical hole is opened in the middle of the back of the tile body 21, and the expansion head of the back bolt is inserted into the conical hole to expand and anchor it. The fixed end of the hanging rod 41 is provided with an external thread for connection with the back bolt, and the hanging rod 41 is fixed to the back bolt by the threaded connection. The end face of the free end of the hanging rod 41 is hemispherical to reduce the frictional resistance when pushed into the horizontal part 312.

[0048] The installation process of the hanging rod 41 and the hanging groove 31 is as follows: the hanging rod 41 enters the vertical part 311 through the opening, slides down in the vertical direction to the bottom of the vertical part 311, at which point the hanging rod 41 reaches the junction of the vertical part 311 and the horizontal part 312, and then pushes the hanging rod 41 into the horizontal part 312 in the horizontal direction. The hanging rod 41 continues to slide horizontally in the horizontal part 312 and abuts against the spring locking member 32. After pushing the spring locking member 32 to elastically deform and retract, it reaches the installation position. The spring locking member 32 returns to its original position and locks the hanging rod 41 in the installation position. When the mounting rod 41 is in the installation position, it rests against the bottom wall of the horizontal part 312, and the vertical weight of the tile unit 2 is rigidly supported by the bottom wall of the horizontal part 312; the out-of-plane suction force causes the mounting rod 41 to move towards the top wall of the horizontal part 312, which is resisted by the rigidity of the top wall of the horizontal part 312; the spring locking member 32 only needs to prevent the mounting rod 41 from sliding out from the horizontal part 312 towards the vertical part 311, and the required locking force is small.

[0049] Furthermore, the spring locking element 32 is a spring ball, which includes a ball and a spring. A mounting hole 323 is provided on the bottom wall of the horizontal portion 312. The mounting hole 323 is a stepped hole. The spring is located within the large-diameter section of the mounting hole 323, and the ball extends out of the small-diameter section of the mounting hole 323. The spring pre-tightens the ball towards the inside of the hook groove 31. The mounting hole 323 is located on the bottom wall of the horizontal portion 312 near the junction of the vertical portion 311 and the horizontal portion 312. When the hook rod 41 slides within the horizontal portion 312, the lower surface of the hook rod 41 passes the ball, pushing the ball to overcome the pre-tightening force of the spring and compress it into the mounting hole 323. After the hook rod 41 passes, the spring pushes the ball back to its original position and out of the mounting hole 323. The ball forms a stop on the side where the hook rod 41 came from, preventing the hook rod 41 from sliding out towards the vertical portion 311. The ball bearings are made of stainless steel and have rolling contact with the hook rod 41. The frictional resistance is small when the hook rod 41 is pushed in, and the installation operation is smooth. The combination of spring and ball bearings remains stable and locked under repeated wind loads, and its fatigue resistance is better than that of cantilever elastic clips.

[0050] Furthermore, such as Figure 3As shown, the keel mounting frame 1 includes multiple vertical main keels 11, which extend vertically. Hook nodes 3 are installed on the vertical main keels 11. Specifically, the vertical main keels 11 are aluminum alloy C-shaped channel steel or hot-dip galvanized rectangular steel pipes, fixed to the main structure of the building wall by expansion bolts or chemical anchors. The spacing of the vertical main keels 11 is determined according to the width of the tile body 21, typically 600 to 1200 mm. Since the brick group bearing module 4 forms a force transmission path in both the vertical and horizontal directions through interlocking connection components, the out-of-plane load is diffused within the brick group bearing module 4 and then jointly borne by multiple hook nodes 3. The keel mounting frame 1 does not need to be equipped with horizontal keels to meet the load-bearing requirements; it only provides the installation foundation for the hook nodes 3 through the vertical main keels 11, reducing the amount of keel material used and the installation process.

[0051] In this embodiment, the brick array support module 4 is a 2×2, 3×3, or 4×4 tile array. Specifically, the array size of the brick array support module 4 is determined based on the size of the individual tile body 21 and the load-bearing capacity of the hanging node 3. The larger the array size, the wider the range of out-of-plane load diffusion, and the smaller the force on a single hanging node 3, but the overall weight and hoisting difficulty of the brick array support module 4 increase accordingly. Taking a 3×3 tile array as an example, when using a 600×600mm tile body 21, the size of the brick array support module 4 is 1800×1800mm, and its weight is about 70 to 90kg. It can be installed as a whole using two suction cups in conjunction with hoisting equipment. Taking the brick group support module 4 of a 3×3 tile array as an example, when the tile body 21 at the center is subjected to an out-of-plane load, if the tile body 21 is independently hung, the out-of-plane load is borne independently by its own hanging node 3. However, in the brick group support module 4, the out-of-plane load of the central tile body 21 is transferred to the two adjacent tile bodies 21 above and below through the vertical connection component 22, and at the same time to the two adjacent tile bodies 21 to the left and right through the horizontal connection component 23, and then continues to spread to the tile bodies 21 in the diagonal directions around the perimeter. Finally, it is shared by multiple hanging nodes 3 around the brick group support module 4, and the out-of-plane load borne by a single hanging node 3 corresponding to the central tile body 21 is significantly reduced. Taking a 3×3 brick group bearing module 4 composed of 9 ceramic tile bodies 21 as an example, when the central ceramic tile body 21 is subjected to an out-of-plane load, the load can be shared by multiple hanging nodes 3 around the brick group bearing module 4 through the diffusion effect of the interlocking connection components. Compared with the method of hanging a single ceramic tile independently, the out-of-plane load borne by a single hanging node 3 can be reduced to less than one-third of the original load. Thus, without increasing the bearing capacity of the hanging node 3, it is possible to use a larger ceramic tile body 21 or reduce the strength requirements of the hanging node 3 and the vertical main keel 11 under the same load conditions.

[0052] Furthermore, both the first connecting plate 221 and the second connecting plate 231 are provided with overflow holes. These overflow holes penetrate the connecting plates, are evenly distributed along the length of the connecting plates, have a diameter of 3 to 5 mm, and a spacing of 30 to 50 mm. The overflow holes are used to drain excess adhesive during bonding. This prevents adhesive from accumulating between the connecting plate and the back of the tile body 21, thus avoiding uneven adhesive layer thickness. Furthermore, observing whether adhesive overflows from the overflow holes indicates whether the bonding is complete and in place, ensuring bonding quality.

[0053] Example 2:

[0054] like Figure 6 As shown, this embodiment provides a construction method for a dry-hanging curtain wall system as described in Embodiment 1, including the following steps:

[0055] S1. Fix the keel mounting frame 1 to the side of the building wall, and install the hanging node 3 on the keel mounting frame 1;

[0056] S2. On the ground, multiple tile units 2 are assembled into a brick group support module 4 by the cooperation of vertical connecting component 22 and horizontal connecting component 23.

[0057] S3. Hoist the brick group support module 4 as a whole and install it on the preset hanging node 3.

[0058] Specifically, in step S1, the vertical main keel 11 is fixed to the main structure of the building wall using expansion bolts or chemical anchors. A theodolite is used to control verticality, and a level is used to measure the horizontal line, ensuring that the verticality deviation of the vertical main keel 11 does not exceed 3mm / 2m. The hanging groove 31 of the hanging node 3 is fixed to the vertical main keel 11 by bolts. During fixing, it is ensured that the vertical part 311 is in the vertical direction, the horizontal part 312 is in the horizontal direction, and the opening faces upwards. The vertical spacing of adjacent hanging grooves 31 is consistent with the vertical spacing of the hanging rods 41 in the brick group bearing module 4, and the horizontal spacing of the hanging grooves 31 on adjacent vertical main keels 11 is consistent with the horizontal spacing of the hanging rods 41 in the brick group bearing module 4.

[0059] In step S2, on the ground operating platform, the first tile body 21 is laid first, and the second tile body 21 is placed above the first tile body 21, so that the insertion groove 224 on the lower edge of the upper tile body 21 is vertically engaged with the insertion tenon 223 on the upper edge of the first tile body 21, with the lower surface of the insertion tenon 223 in close contact with the lower surface of the insertion groove 224; then the third tile body 21 is placed to the right of the first tile body 21, so that the tenon 233 on the left edge of the right tile body 21 is horizontally engaged with the slot 234 on the right edge of the first tile body 21; the assembly is expanded in sequence, so that each tile body 21 establishes a connection relationship with the adjacent tile bodies 21 above, below, left, and right, and finally forms the brick group support module 4. During the assembly process, the position of each insertion and engagement surface is checked simultaneously to ensure that the insertion tenon 223 is fully embedded in the insertion groove 224 and the tenon 233 is fully engaged in the slot 234.

[0060] In step S3, the brick group support module 4 is lifted as a whole using a suction cup or lifting clamp. The hanging rod 41 on the back of the brick group support module 4 is aligned with the opening of the hanging groove 31. The brick group support module 4 is lowered as a whole so that the hanging rod 41 enters the vertical part 311 through the opening. Then, the brick group support module 4 is pushed horizontally so that the hanging rod 41 slides from the vertical part 311 into the horizontal part 312. After the hanging rod 41 abuts against the spring locking member 32 in the horizontal part 312, it reaches the installation position. The spring locking member 32 returns to its original position and locks the hanging rod 41, thus completing the installation of the brick group support module 4.

[0061] Furthermore, in step S2, during the formation of the brick group support module 4, multiple hanging rods 41 are pre-installed on the corresponding positions on the back of the brick group support module 4, so that the brick group support module 4, after assembly, forms an integral installation unit that can directly cooperate with the hanging node 3. Specifically, before assembling the brick group support module 4, a tapered hole is first opened in the middle of the back of each tile body 21 and a back bolt is inserted. Then, the hanging rod 41 is threaded to the back bolt, ensuring that the hanging rod 41 is perpendicular to the back of the tile body 21. Then, during the assembly process, the positional accuracy of each hanging rod 41 is checked simultaneously to ensure that the spacing of each hanging rod 41 after the brick group support module 4 is assembled matches the spacing of the hanging groove 31 on the keel mounting frame 1.

[0062] Further, in step S2, each tile unit 2 is connected to its upper and lower adjacent tile units 2 and its left and right adjacent tile units 2, so that a two-dimensional continuous force transmission network is formed inside the brick group bearing module 4, running through multiple tile units 2. Specifically, the upper and lower edges of each tile body 21 are connected to adjacent tile bodies 21 through vertical connecting components 22, and the left and right edges are connected to adjacent tile bodies 21 through horizontal connecting components 23, so that the out-of-plane load on any tile body 21 inside the brick group bearing module 4 can be transmitted and diffused to the surroundings through interlocking connecting components, and finally shared by multiple hanging nodes 3 on the edge of the brick group bearing module 4. Taking the brick group support module 4 of a 3×3 tile array as an example, when the tile body 21 at the center is subjected to an out-of-plane load, the load is first transferred to the adjacent tile bodies 21 above and below through the vertical connection component 22, and at the same time transferred to the adjacent tile bodies 21 to the left and right through the horizontal connection component 23, and then continues to spread to the surrounding area. Finally, it is shared by multiple hanging nodes 3 around the brick group support module 4. The force on a single hanging node 3 is significantly lower than the force on the tile body 21 when it is hung independently.
