Description

Technical Field

[0001] This invention belongs to the field of interior decorative wall construction, specifically an integrated twisted shaped wall structure with seaweed-like surface decoration and its construction method. Background Technology

[0002] With the increasing demand for interior decorative walls featuring complex curved shapes, both domestic and international requirements for intricate wall designs and precise construction have presented significant challenges to traditional construction methods. When designers create interior decorative walls, they often focus solely on design concepts and flexibility, neglecting to specify materials. Therefore, actual construction necessitates secondary design refinement to meet the client's needs and ensure on-site implementation.

[0003] When a twisted wall structure is combined with cantilever panels to create a seaweed-like surface decoration, using traditional stone as the decorative panel results in a significant weight, increasing the difficulty of detailed design and construction. Furthermore, the design concept of the seaweed-like twisted wall is incompatible with the use of stone panels. While GRG (glass fiber reinforced gypsum) decorative panels offer good plasticity and lightweight properties, the seaweed-like surface decoration requires a row of cantilever panels protruding beyond the decorative layer surface, typically exceeding one meter to achieve the desired visual effect. However, GRG material has limited bending strength and cannot withstand the large bending moments generated by such large-span cantilever structures, posing a risk of breakage. Therefore, achieving an integrated twisted wall structure incorporating seaweed-like surface decoration, ensuring the wall's stability, secure connections, and integrated construction of the wall panels, overcoming technical difficulties during installation, improving construction efficiency and quality, and ensuring the overall decorative effect require targeted design to transform the integrated twisted wall structure incorporating seaweed-like surface decoration into a feasible physical project. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated twisted wall structure with seaweed-like surface decoration and its construction method. It aims to solve the problems of how to present interior decorative walls under the shape of an integrated twisted wall structure with seaweed-like surface decoration, the insufficient strength of GRG material in large-span cantilever decoration, how to achieve stable connection of such decorative walls, and the technical problems of integrated design and construction of wall panel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An integrated twisted wall structure with a seaweed-like surface decoration includes a wall body. The wall body includes a decorative keel and a GRG board decorative surface layer connected to the surface of the decorative keel. The GRG board decorative surface layer includes a smooth part and a shaped part. The smooth part has a smooth surface profile, and the smooth part and the shaped part have continuously connected profiles. The shaped part is located at one end of the wall body, and its surface profile is a composite curved surface combining a layered stepped shape and a twisted curved surface in three-dimensional space. The stepped profile is formed by a group of cantilevered panels arranged in layers along the height direction and extending horizontally away from the wall surface. The surface of the decorative section is also equipped with cantilevered decorative panels, which are distributed along the height of the wall. Their distribution corresponds to the stepped outline. The cantilevered decorative panels are bird-beak shaped and are integrally formed with the cantilevered slabs of the corresponding level. The bottom surface of the cantilevered decorative panels is flush with the bottom surface of the cantilevered slabs of the corresponding level. The sides of the cantilevered decorative panels smoothly connect with the side surfaces of the cantilevered slabs of the corresponding level and extend from both ends towards the middle to converge and form a pointed end. The cantilever length, panel span, or tip position of the cantilever decorative panel gradually change as the composite curved surface twists and steps upwards. The cantilever length gradually shortens from bottom to top, the panel span gradually narrows from bottom to top, and the tip position is in a dynamic wave shape, together forming a three-dimensional decorative surface with a biomimetic seaweed-like front outline.

[0006] The cantilever slab has a C-shaped cross-section with its opening facing the inner side of the wall. It includes a horizontal base plate, curved side plates, and a horizontal inner top plate. The horizontal base plate includes a horizontal inner bottom plate and a horizontal cantilever slab extending horizontally away from the cantilever slab to form a horizontal external decorative cantilever slab. The horizontal projection of the horizontal external decorative cantilever slab is triangular. The two sides of the triangle smoothly connect with the surface of the curved side plate and extend upwards from both ends of the base to meet. From the middle of the curved side plate and the upper left and right sides of the horizontal external decorative cantilever slab, arches are formed to transition and connect to form curved tie arches. The curved tie arches on both sides form extended curved ridges at their apex. The horizontal external decorative cantilever slab is obliquely connected by the curved tie arches, and the horizontal external decorative cantilever slab and the curved tie arches form a cantilever decorative panel. The horizontal inner bottom plate of the upper cantilever plate and the horizontal inner top plate of the lower cantilever plate are stacked and fixedly connected. The curved surface shape of the curved side plate and the composite curved surface are adaptively set.

[0007] The GRG panel decorative surface layer is constructed by splicing prefabricated GRG unit blocks, divided into smooth sections and shaped sections. The direction of the joints is determined by the stepped contours and cantilevered decorative panel shapes within the shaped unit block areas. Horizontal dividing joints are arranged at intervals along the length of the wall, and are set at the junction of two adjacent cantilever slabs. The smooth longitudinal segmentation joints of the smooth unit blocks are arranged at intervals along the horizontal segmentation joints of each layer, and are vertically set along the wall. The longitudinal dividing seams of the styling unit blocks are arranged at intervals along the horizontal dividing seams of each layer, and are set in the transition area between adjacent cantilever decorative panels to ensure the integrity of the cantilever decorative panels in the styling unit block area.

[0008] The design unit block includes a decorative block containing a cantilevered decorative panel and a transition block not containing a cantilevered decorative panel. The decorative blocks are connected to each other or to the transition blocks. The length of the decorative block is greater than the maximum span of the cantilevered decorative panel within the block.

[0009] The styling unit block includes three or more cantilevered slabs. The horizontal dividing seam is located between the horizontal bottom plate and the horizontal top plate of two adjacent cantilevered slabs. The edges of two horizontally adjacent GRG unit blocks are provided with splicing plates, and the splicing plates are rigidly connected by locking through connectors.

[0010] The back of the GRG unit block is pre-embedded with a T-shaped connector that is fixedly connected to the decorative keel. This includes a pre-embedded flat plate embedded in the back side of the GRG unit block, and a side-mounted cantilever plate that is vertically fixed to the center of the pre-embedded flat plate and extends out of the surface of the GRG unit block. The pre-embedded flat plate in the styling unit block is set in the curved side plate.

[0011] Decorative framing includes vertical framing and horizontal framing. Vertical framing includes wall columns spaced apart along the wall structure. Horizontal framing includes main horizontal beams spaced apart between the wall columns along the height direction, and cantilever connecting beams that are perpendicularly fixed to the main horizontal beams and extend toward the GRG panel decorative surface. The cantilever connecting beams are correspondingly installed and fixedly connected to the side-mounted cantilever panels. Two main crossbeams are set at intervals for each GRG unit block on the same floor, namely the top crossbeam and the bottom crossbeam. Two rows of pre-embedded T-shaped connectors are set on the back side of each GRG unit block. The top row of T-shaped connectors corresponds to the top crossbeam, and the bottom row of T-shaped connectors corresponds to the bottom crossbeam. There are more than two T-shaped connectors in each row. The T-shaped connectors of the shaping unit block are set in the curved side plates of the uppermost and lowermost cantilever plates of the shaping unit block.

[0012] The decorative keel within the styling section is further equipped with a cantilever frame adapted to the cantilever distance of the styling unit block. The cantilever frame includes a cantilever extension beam fixed to the side of the wall column and extending outwards. The front end of the adjacent cantilever extension beam is supported by a side crossbeam. The cantilever connecting beam is fixedly connected to the end of the cantilever extension beam and / or the side crossbeam. The cantilever connecting beam is fixed in parallel or radially within the cantilever frame. The adjacent cantilever extension beams are connected in parallel or cross directions.

[0013] The decorative keel also includes end tie rods. The ends of the main crossbeams are connected as one unit by end tie rods, and the outline of the end tie rods is adapted to the outline of the styling part.

[0014] An integrated twisted wall structure with seaweed-like surface decoration, the construction steps are as follows: S1. Based on the target wall shape, a parametric digital model is created using 3D design software. The core driving parameters include the torsion angle of the composite surface, the step height difference and surface curvature characteristics, as well as the cantilever length, panel span and the setting position characteristics of the apex of the cantilever decorative panel, to generate the composite surface and the gradient seaweed-like decorative surface distributed on it. S2, Design the area range of the smooth part and the shape part according to the digital model, and design the block seam position of each GRG unit block according to the stepped contour and the distribution of the cantilever decorative panel. The GRG panel decorative surface layer is divided into prefabricated GRG unit blocks. When dividing, ensure the integrity of each cantilever decorative panel in the decorative block. S3, based on the stress design, the pre-embedded position and number of each T-type connector in each GRG unit block, and at the same time design the form and specifications of the decorative keel, wherein the horizontal keel is designed in correspondence with the T-type connector, and each GRG unit block is assigned a code and three-dimensional spatial coordinate information installed on the decorative keel; S4. Based on the models of each GRG unit block obtained in the steps, the molds that make up each GRG unit block are manufactured in the factory using three-dimensional CNC engraving. These include standard molds for smooth unit blocks and special molds for shaped unit blocks including various levels of cantilever boards. The standard molds and special molds are engraved on wood or foam blanks. T-shaped connectors are pre-embedded in the standard molds and special molds. The T-shaped connectors in the special molds are pre-embedded in the curved side plates of the corresponding cantilever boards. Then, GRG material is poured, cured, and demolded to form smooth unit blocks and various levels of cantilever boards. Then, the various levels of cantilever boards are assembled and stacked according to the design to form shaped unit blocks 24. S5, Decorative keel construction, constructing decorative keels according to the digital model and installing a specially designed L-shaped rooting structure for the cantilevered frame in the cantilevered area of ​​the shaping part; S6. Hoist the GRG unit blocks according to their codes and place them in the designed positions. On-site, based on the design distance between the main crossbeam and / or cantilever frame in the decorative keel and the GRG unit blocks, cut the cantilever connecting beam between them to a suitable length. A space is reserved between the front end of the cantilever connecting beam and the T-shaped connector. The front sidewall of the cantilever connecting beam fits snugly against the corresponding T-shaped connector. The rear end of the cantilever connecting beam overlaps the main crossbeam and / or cantilever frame. Then, the installation position of the GRG unit blocks is precisely positioned using the cantilever connecting beams welded on-site. During positioning, the side cantilever plate of the T-shaped connector on the back of the GRG unit block is initially attached to the corresponding cantilever connecting beam. The three-dimensional actual spatial coordinates of the GRG unit block are measured using a total station. The spatial angle and position of the cantilever decorative plate are adjusted. The apex of the triangle is used as the reference point and compared with the theoretical coordinates in the digital model to ensure that the cantilever length, gradation law, and plate torsion angle of each layer of cantilever decorative plate on the same vertical sequence are consistent with the design model, and to ensure the continuity and dynamism of the overall seaweed-like shape. During the fixing process, the T-shaped connector is first welded to the cantilever connecting beam, and then the cantilever connecting beam is welded to the cantilever frame. After each layer of GRG unit blocks is constructed, the splicing plates at the splicing positions of each GRG unit block are rigidly connected by locking with through connectors. S7. Repeat step S6 until all GRG panel decorative surfaces are completed. Fill the joints between all GRG unit blocks with decorative sealant containing fiberglass, attach anti-crack mesh, and finally apply a full coat, sand, and surface treatment to complete the construction.

[0015] Compared with the prior art, the present invention has the following features and beneficial effects: I. This invention solves the problem of insufficient strength of GRG material in large-span cantilever decorations by using a stepped, layered C-shaped cantilever structure, achieving a balance between structural safety and aesthetics. The invention embeds the seaweed-like decorative cantilever panels of the decorative section onto a stepped, multi-layered C-shaped cantilever structure formed by stacking and fixing the panels along the height direction. Each level of the C-shaped cantilever is itself a stable box-shaped or trough-shaped component with good bending and torsional resistance. The cantilever decorative panel is designed in a bird's beak structure form, integrally formed with the cantilever panel of its level. The horizontal outer decorative cantilever panel is formed by extending the horizontal base plate outwards. The curved transition arch of the curved side panel transitions obliquely to and connects with the horizontal outer decorative cantilever panel, allowing the load of the cantilever decorative panel to be directly transferred to the C-shaped cantilever panel of that level. The upper and lower cantilever slabs are stacked and fixed, so that the load is transferred downwards in the form of pressure and friction through the overlapping surface, reducing the single-point stress of the horizontal exterior decorative cantilever slab. The C-shaped cantilever slab where the cantilever decorative slab is located is both the structure itself and the shape. While achieving a twisted seaweed-like visual effect, it forms a stable spatial force-bearing frame. Through this stepped layered reinforced structural design, the GRG material can achieve a dynamic cantilever decorative effect and bear complex dynamic shapes.

[0016] Second, this invention establishes a parameterized digital model, which uses styling parameters, including the gradient features of the cantilever decorative panel, such as cantilever length, panel span, tip position, and composite curved surface shape, as the driving force for the breakdown, production, and construction of design unit blocks. This ensures the accuracy of the spatial form and gradient law of the cantilever decorative panel, and provides a precise data foundation and coordinated control for the entire process of cantilever decorative panel from design to construction.

[0017] Third, this invention addresses the complex shapes and high spatial positioning requirements of cantilever decorative panels by dividing the overall surface layer into prefabricated GRG unit blocks. The segmentation strategy of these unit blocks prioritizes the integrity of each cantilever decorative panel, enabling one-time molding in a factory environment. Special molds are manufactured using 3D CNC engraving, and integrated casting is achieved using pre-embedded T-shaped connectors. This produces cantilever decorative panel units with accurate shapes that integrate with the C-shaped cantilever panels, overcoming the difficulty of workers molding complex cantilever shapes on-site and ensuring the structural strength and shaping accuracy of the cantilever panels themselves.

[0018] IV. To achieve precise positioning of the cantilevered decorative panel, this invention incorporates a decorative keel reinforced with a cantilevered frame structure in the shaping section. The T-shaped connectors on the back of the GRG unit blocks are all connected by cantilevered connecting beams of cutable length, allowing for on-site adaptive adjustment of the connection distance between the GRG unit blocks and the keel. During installation, the triangular apex of the cantilevered decorative panel is used as a key reference point. A total station is used for three-dimensional coordinate measurement and adjustment to ensure that its spatial angles, positions, and gradation patterns are completely consistent with the design model. Subsequently, a rigid connection is achieved through welding, ensuring the accurate presentation of the final dynamic shape and overall stability. Attached Figure Description

Detailed Implementation

[0038] See the examples. Figure 1-3As shown, in a certain high-end decoration project, the lobby background wall adopts an integrated twisted shape wall with seaweed-like surface decoration. The background wall is over 9 meters high. The wall includes a decorative keel 1 and a GRG board decorative surface layer 2 connected to the surface of the decorative keel 1. The GRG board decorative surface layer 2 includes a smooth part 21 and a shaped part 22. The surface contour of the smooth part 21 is smooth, and the contours of the smooth part 21 and the shaped part 22 are continuously connected. The shaped part 22 is located at one end of the wall. Its surface contour is a composite curved surface that combines a layered stepped shape with a twisted curved surface in three-dimensional space. The stepped contour is formed by a group of cantilevered panels arranged in layers along the height direction and extending horizontally away from the wall surface.

[0039] See Figure 1-3 As shown in Figure 5, the surface of the shaping part 22 is also provided with a cantilever decorative panel 3. The cantilever decorative panel 3 is distributed along the height direction of the wall, and its distribution position corresponds to the stepped outline. The cantilever decorative panel 3 is in the shape of a bird's beak and is integrally formed with the cantilever plate 4 of the same level. The bottom surface of the cantilever decorative panel 3 is flush with the bottom surface of the cantilever plate 4 of the same level. The side surface of the cantilever decorative panel 3 is smoothly connected to the side surface of the cantilever plate 4 of the same level and extends from both ends to the middle to form a pointed part 44.

[0040] The cantilever length, panel span, or the position of the tip 44 of the cantilever decorative panel 3 gradually changes with the upward twisting and stepping of the composite curved surface. The cantilever length gradually shortens from bottom to top, the panel span gradually narrows from bottom to top, and the position of the tip 44 is in a dynamic wave shape, which together form a three-dimensional decorative surface with a biomimetic seaweed-like front outline.

[0041] In this embodiment, see Figure 5-7 As shown, the cross-section of the cantilever 4 is C-shaped, with its opening facing the inner side of the wall. It includes a horizontal base plate 41, a curved side plate 42, and a horizontal inner top plate 43. The horizontal base plate 41 includes a horizontal inner base plate 411 and a horizontal outer decorative cantilever plate 412. The horizontal projection of the horizontal outer decorative cantilever plate 412 is triangular. It extends horizontally cantilevered away from the bottom edge of the triangle away from the cantilever 4. The two sides of the triangle are smoothly connected to the surface of the curved side plate 42 and extend upward from the two ends of the bottom edge to meet. From the middle of the curved side plate 42, the left and right sides above the horizontal outer decorative cantilever plate 412 respectively arch and connect to form a curved connecting arch plate 421. The curved connecting arch plates 421 on both sides form an extended curved arch ridge 422 at the tip 44. The horizontal outer decorative cantilever plate 412 is obliquely connected by the curved connecting arch plate 421. The horizontal outer decorative cantilever plate 412 and the curved connecting arch plate 421 form a cantilever decorative plate 3.

[0042] The horizontal inner bottom plate 411 of the upper cantilever plate 4 and the horizontal inner top plate 43 of the lower cantilever plate 4 are stacked and fixedly connected. The curved surface shape of the curved side plate 42 is adapted to the composite curved surface.

[0043] In this embodiment, see Figure 4 As shown, the GRG panel decorative surface layer 2 is formed by splicing prefabricated GRG unit blocks divided by segmentation seams, including smooth unit blocks 23 of smooth part 21 and shaped unit blocks 24 of shaped part 22. The direction of the segmentation seams is set according to the stepped contour of the shaped unit block area and the shape of the cantilever decorative panel 3.

[0044] The block division principle is as follows: Horizontal segmentation joints 5 are arranged at intervals along the length of the wall and are set in the junction area of ​​two adjacent cantilever slabs 4; The smooth longitudinal dividing seams 6 of the smooth unit block 23 are arranged at intervals along the horizontal dividing seams 5 of each layer, and are set vertically along the wall. The longitudinal dividing seams 7 of the styling unit block 24 are arranged at intervals along the horizontal dividing seams 5 of each layer, and are set in the styling transition area between adjacent cantilever decorative panels 3, so as to ensure the integrity of the cantilever decorative panels 3 in the styling unit block area.

[0045] Each styling unit 24 includes five layers of cantilever slabs 4, meaning that the styling unit 24 is formed by stacking and connecting five layers of cantilever slabs 4. The horizontal dividing seam 5 needs to be located between the horizontal bottom plate 41 of the upper cantilever slab and the horizontal top plate 43 of the lower cantilever slab of two adjacent styling unit 24. The edges of two horizontally adjacent GRG unit blocks are provided with splicing plates 25, and the splicing plates 25 are rigidly connected by locking them together with through connectors 8.

[0046] After the styling unit block 24 is divided into blocks, it includes a decorative block 241 containing a cantilever decorative panel 3 and a transition block 242 not containing a cantilever decorative panel 3. The decorative block 241 is connected to the decorative block 241 or the transition block 242. The length of the decorative block 241 is greater than the maximum span of the cantilever decorative panel 3 within the block.

[0047] See Figure 8-16 As shown, the back of the GRG unit block is pre-embedded with a T-shaped connector 9 that is fixedly connected to the decorative keel 1. This includes a pre-embedded flat plate 91 pre-embedded on the back side of the GRG unit block, and a side-mounted cantilever plate 92 that is vertically fixedly connected to the center of the pre-embedded flat plate 91 and extends out of the surface of the GRG unit block. The pre-embedded flat plate 91 in the styling unit block 24 is set in the curved side plate 42.

[0048] In this embodiment, the decorative keel 1 includes vertical keels and horizontal keels. The vertical keels include wall columns 11 spaced apart along the wall structure. The horizontal keels include main horizontal beams 12 spaced apart between the wall columns 11 along the height direction and cantilever connecting beams 13 that are vertically fixed to the main horizontal beams 12 and extend toward the GRG board decorative surface layer 2. The cantilever connecting beams 13 are correspondingly arranged and fixedly connected to the side-attached cantilever panels 92.

[0049] Two main crossbeams 12 are set at intervals for each GRG unit block on the same layer, namely the top crossbeam 121 and the bottom crossbeam 122. Two rows of pre-embedded T-shaped connectors 9 are set on the back side of each GRG unit block. The top row of T-shaped connectors 9 is set for the top crossbeam 121, and the bottom row of T-shaped connectors 9 is set for the bottom crossbeam 122. There are more than two T-shaped connectors 9 in each row. The T-shaped connectors 9 of the shaping unit block 24 are set in the curved side plates 42 in the uppermost cantilever plate 4 and the lowermost cantilever plate 4 of the shaping unit block 24.

[0050] The decorative keel 1 within the range of the shaping section 22 is further provided with a cantilever frame adapted to the cantilever distance of the shaping unit block 24. The cantilever frame includes a cantilever extension beam 101 fixed to the side of the wall column 11 and extending out. The front end of the adjacent cantilever extension beam 101 is supported by a side crossbeam 102. The cantilever connecting beam 13 is fixedly connected to the end of the cantilever extension beam 101 and / or the side crossbeam 102. The cantilever connecting beam 13 is fixed in parallel or radially within the cantilever frame. The adjacent cantilever extension beams 101 are connected in parallel or cross directions.

[0051] The decorative keel 1 also includes end tie rods 10, which connect the ends of the main crossbeams to each other. The contour of the end tie rods 10 is adapted to the contour of the shaped part. The cantilever connecting beams 13 are radially fixed in the cantilever frame and are generally set at the high torsional shaped position. In this embodiment, at the high torsional shaped position, adjacent cantilever extension beams 101 are cross-connected and together with the side crossbeams 102 form a triangular brace, which helps the outer cantilever connecting beams 13 to form a radial arrangement.

[0052] The construction steps for this integrated twisted wall structure with seaweed-like surface decoration are as follows: S1. Based on the target wall shape, a parametric digital model is established using 3D design software. The core driving parameters include the torsion angle of the composite surface, the step height difference and surface curvature characteristics, as well as the cantilever length of the cantilever decorative panel 3, the panel span and the setting position characteristics of the apex of the triangle 44, to generate the composite surface and the gradient seaweed-like decorative surface distributed on it. S2, Design the respective area range of the smooth part 21 and the shaping part 22 according to the digital model, and design the block seam position of each GRG unit block according to the stepped contour and the distribution of the cantilever decorative panel 3. The GRG board decorative surface layer 2 is divided into prefabricated GRG unit blocks. When dividing, ensure the integrity of each cantilever decorative panel 3 in the decorative block 241. S3, based on the stress design, the pre-embedded position and number of each T-type connector in each GRG unit block, and at the same time design the form and specifications of the decorative keel 1, wherein the horizontal keel and the T-type connector 9 are designed accordingly, and each GRG unit block is assigned a code and three-dimensional spatial coordinate information installed on the decorative keel 1. S4. Based on the models of each GRG unit block obtained in step S2, molds for each GRG unit block are manufactured in the factory using 3D CNC engraving. These include a standard mold for the smooth unit block 23 and a special mold 20 for the shaped unit block 24, which includes various levels of cantilever plates 4. Both the standard and special molds 20 are engraved from uniform wood or foam blanks. T-shaped connectors 9 are pre-embedded in both the standard and special molds 20. In the special mold 20, the T-shaped connectors 9 are pre-formed within the curved side plates 42 of the corresponding cantilever plates 4. Then, GRG material is poured in, cured, and demolded to form the smooth unit block 23 and the various levels of cantilever plates. Finally, the various levels of cantilever plates 4 are assembled and stacked according to the design to form the shaped unit block 24. The thickness of each cantilever plate is 15mm. See the special mold 20 for details. Figure 17 .

[0053] S5, Decorative keel construction: construct decorative keel 1 according to the digital model and install the L-shaped rooting structure of the specially designed cantilever frame in the cantilever area of ​​the shaping section 22; the wall column 11 is a square steel tube of 150mm×150mm×8mm or 60mm×40mm×4mm, with a vertical spacing of ≦1200mm; the main beam 12, cantilever connecting beam 13, cantilever extension beam 101, side beam 102 and end tie rod 10 are of model L50mm×5mm.

[0054] S6. Hoist the GRG unit blocks to their designated positions according to their codes. On-site, based on the design distance between the main crossbeam 12 and / or the cantilever frame in the decorative keel 1 and the GRG unit blocks, cut the cantilever connecting beam 13 to a suitable length. A space is reserved between the front end of the cantilever connecting beam 13 and the T-shaped connector 9. The front sidewall of the cantilever connecting beam 13 fits snugly against the corresponding T-shaped connector 9. The rear end of the cantilever connecting beam 13 overlaps the main crossbeam 12 and / or the cantilever frame. Then, the installation position of the GRG unit blocks is precisely positioned using the cantilever connecting beam 13 welded on-site. During positioning, the side cantilever plate 92 of the T-shaped connector 9 on the back of the GRG unit block is initially attached to the corresponding cantilever connecting beam 13. The three-dimensional actual spatial coordinates of the GRG unit block are measured using a total station. The spatial angle and position of the cantilever decorative plate 3 are adjusted. The apex 44 of the triangle is used as the reference point and compared with the theoretical coordinates in the digital model to ensure that the cantilever length, gradation law, and plate torsion angle of each layer of cantilever decorative plate 3 in the same vertical sequence are consistent with the design model, and to ensure the continuity and dynamism of the overall seaweed-like shape. During fixing, the T-shaped connector 9 is first welded to the cantilever connecting beam 13, and then the cantilever connecting beam 13 is welded to the cantilever frame. After each layer of GRG unit blocks is constructed, the splicing plates 25 at the splicing positions of each GRG unit block are rigidly connected by locking with through connectors 8. S7. Repeat step S6 until all GRG panel decorative surface layer 2 is completed. Fill the joints between all GRG unit blocks with decorative joint filler material 30 containing glass fiber, attach anti-crack mesh cloth, and finally apply full coat, sand and treat the surface to complete the construction.
