Description

Technical Field

[0001] This invention relates to the field of statue construction technology, specifically to a method and structure for constructing large Buddha statues. Background Technology

[0002] A search revealed that patent application number CN202310459381.9 discloses a construction structure and method for a statue. This technology breaks down a large statue into multiple prefabricated "statue panels," which are transported to the site and then assembled. During construction, while assembling the outer shell, a "frame structure" is built internally as the main support. "Tie grooves" and "limiting auxiliary holes" are opened at the joints of the statue panels, and "tie members" are inserted. Subsequently, formwork is erected around the frame, and the other end of the tie member is tied and welded to the "tie body steel bar." Finally, concrete is poured to form a "concrete wall" that is integrated with the frame. Thus, the outer stone slabs and the internal structure are tied together as a whole through the tie members. This method is usually constructed in layers along the height direction, and floor slabs are set to distribute the load.

[0003] However, the above methods are mainly designed for general figure sculptures. When applied to religious statues with large backlights (such as Buddha statues), they face new technical challenges. The backlights often have characteristics such as large overhangs, complex shapes, and wide wind exposure areas. For large Buddha statues (overall height greater than 30m), the backlight size is huge, which will form a significant eccentric load and bear huge wind loads in severe weather. The concrete wall tying system in the existing methods is difficult to directly and effectively solve the problems of stable connection, load transfer, and wind and earthquake resistance of such irregular, non-load-bearing but huge decorative components, which may become a potential weak point in the overall structural safety.

[0004] Based on the above problems, a construction method for large-scale Buddha statues and its construction structure technical solution are proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a construction method and structure for large-scale Buddha statues.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a method for constructing large Buddha statues, comprising: S1: Based on the artistic design of the Buddha statue's main body and backlight, a three-dimensional digital model containing both is established, and load simulation and stress analysis are performed on the three-dimensional digital model. S2: Based on the data in S1, the model is structurally and topologically optimized, and the model is clearly divided into the Buddha statue body with local solid filling and the backlight of the hollow area; S3: Conduct structural design for the main body and halo of the Buddha statue, specifically including: S3.1: Based on the partitioning results and stress analysis data, the truss-type structural reinforcement system configuration inside the Buddha statue body and the lightweight spatial truss skeleton system inside the backlight are generated by the finite element topology optimization method, and the cross-sectional dimensions, connection node forms and material strength grades of each component are determined. S3.2: For the junction area between the Buddha statue body and the backlight, a special connecting transition structure with three-dimensional adjustment function is designed. The special connecting transition structure is analyzed based on the data in S3.1 to confirm the position, quantity and distribution density of the special connecting transition structure between the Buddha statue body and the backlight. The special connecting transition structure includes pre-embedded anchors and three-dimensional adjustment components. The pre-embedded anchors are respectively set at the junction of the Buddha statue body and the backlight, and the three-dimensional adjustment components are set between the pre-embedded anchors. S3.3: Based on the structure of S3.1 and S3.2, generate CNC cutting data for each steel structure component, welding and assembly process data for each connection node, and surface development and boundary control point data for modular segmentation of decorative panels. S4: Based on the processing data of S3, the decorative panels for the Buddha statue body and the backlight, as well as the corresponding connecting steel structures, are produced separately using a modular unit approach. S5: The physical structure of the Buddha statue is constructed layer by layer from bottom to top. After each layer is constructed, the physical shape is obtained through 3D scanning and compared with the digital model to dynamically guide the construction of the next layer. S6: After the main body of the Buddha statue reaches the design elevation and the filling material reaches the design strength, the backlight unit is installed and fixed to the main body of the Buddha statue through a special connecting transition structure; S7: Perform overall surface treatment and data testing on the installed Buddha statue body and backlight.

The locking bolt assembly is respectively disposed between the vertical elongated hole and the horizontal elongated hole, and is used to adjust the position of the first adjusting plate and the second adjusting plate in the vertical direction and the position of the second adjusting plate and the mounting plate in the horizontal direction.

[0011] The present invention is further configured such that: the locking bolt assembly includes a vertical bolt group and a horizontal bolt group; The vertical bolt group consists of a bolt passing through the vertical elongated hole and a locking nut. The bolt head or nut abuts against the second adjusting plate. By loosening the nut, the second adjusting plate slides up and down along the vertical elongated hole to the desired position and then re-locks it to achieve vertical adjustment. The horizontal bolt assembly consists of a bolt passing through the horizontal elongated hole and a locking nut. The bolt shank is fixed to the mounting plate.

[0012] The invention is further configured such that: a ball joint structure is provided between the second adjustment plate and the mounting plate, the ball joint structure includes a ball head seat and a ball head rod, the ball head seat is fixed to the front of the second adjustment plate, one end of the ball head rod is a ball head and is accommodated in the ball head seat to form universal rotation, and the other end of the ball head rod is fixedly connected to the mounting plate to realize a small angle deflection adjustment of the backlight relative to the main body of the Buddha statue. After the adjustment is completed, the ball head seat and the ball head rod are fixed by locking screws.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] A method for constructing large Buddha statues, such as Figure 1 as well as Figure 2 As shown, the specific steps include: S1: Based on the artistic design of the Buddha statue body 1 and the halo 2, a three-dimensional digital model containing both is established, and load simulation and stress analysis are performed on the three-dimensional digital model. Specifically, load simulation and stress analysis include: strength, stiffness and stability analysis of the three-dimensional digital model under wind load, seismic action and self-weight action; through finite element analysis, accurately obtain the stress distribution, deformation characteristics and potential instability areas of the model under different load combinations, provide key data support for subsequent structural topology optimization, and can identify structural weak links in advance to ensure the safety benchmark of subsequent design.

[0019] S2: Based on the data in S1, perform structural topology optimization on the model. The goal of the optimization is to achieve the optimal distribution of materials, that is, to minimize the use of materials in non-stressed areas while ensuring the overall stress performance and stiffness of the structure. The topology optimization algorithm specifically employs the SIMP algorithm based on the variable density method, implemented using professional software such as TOSCA or OptiStruct. The specific optimization scheme is as follows: the backlight region 2 is taken as the design domain, while the Buddha statue body region 1 is forcibly retained as a non-design domain. The design domain is discretized into element pseudo-density variables ρ. e ∈[0,1], with the goal of minimizing the overall structural compliance (i.e. maximizing stiffness), and with constraints that the volume fraction of the design domain does not exceed 30% and the equivalent stress of all elements is less than 80% of the material yield strength, an optimization mathematical model is established and iteratively solved using the moving asymptotic method. The convergence criterion is set to the maximum change of the design variables in two consecutive iterations being less than 0.01. During the optimization process, symmetry constraints and draft constraints are combined to ensure the process feasibility and shape symmetry of the backlight 2 frame, and finally a clear force transmission path and a truss-like topology configuration are obtained. Using a topology optimization algorithm, the model was clearly divided into two regions with distinct functions and structures: the Buddha statue body 1 region, which mainly bears compressive stress and needs to reflect a sense of heavy volume, was defined as a partially solid infilled region; the backlight 2 region, which mainly bears wind load and its own weight, was designed as a hollow region due to its flowing shape and significant impact on the overall structural stability. This laid the foundation for the subsequent design of the high-load-bearing internal structure of the Buddha statue body 1 and the lightweight backlight 2 skeleton.

[0020] S3: Conduct structural design for the Buddha statue body 1 and the halo 2, specifically including: S3.1: Based on the results of topology optimization, the structural reinforcement system configuration inside the Buddha statue body 1 and the lightweight skeleton system inside the backlight 2 are generated respectively. For the Buddha statue body 1, a spatial structural reinforcement system composed of steel frame and steel mesh is generated to bear the self-weight of the upper filling material and external load. For the backlight 2, a spatial truss type 5 lightweight skeleton system composed of main load-bearing members and secondary stable members is generated. This system achieves significant structural weight reduction while ensuring sufficient stiffness and wind resistance. The cross-sectional dimensions, connection node forms and material strength grades of each component are determined. S3.2: For the junction area between the Buddha statue body 1 and the backlight 2, a special connecting transition structure with three-dimensional adjustment function is designed. The special connecting transition structure is based on the load transfer path analysis of the data in S3.1 to confirm the position, quantity and distribution density of the special connecting transition structure between the Buddha statue body 1 and the backlight 2. Specifically, the special connecting transition structure in S3.2 includes pre-embedded anchors and three-dimensional adjustment components. The pre-embedded anchors are respectively set at the junction of the Buddha statue body 1 and the backlight 2, and the three-dimensional adjustment components are set between the pre-embedded anchors. S3.3: Based on the structure of S3.1 and S3.2, generate CNC cutting data for each steel structure component, welding and assembly process data for each connection node, and surface development and boundary control point data for modular segmentation of the decorative panel.

[0021] S4: Based on the processing data of S3, the decorative panels 3 of the Buddha statue body 1 and the backlight 2, as well as the corresponding connecting steel structures 4, are produced separately using a modular unit method. Specifically, the modular unit method in S4 is as follows: based on the three-dimensional digital model and structural system, the surfaces of the Buddha statue body 1 and the backlight 2 are divided into multiple spatial curved surface modules. Each spatial curved surface module is accompanied by a unique number and spatial positioning coordinates. Subsequently, according to the segmentation data, metal plates or composite material plates are precisely cut using CNC equipment to form the decorative panels 3, and the steel components designed in S3.1 are prefabricated in the factory.

[0022] S5: The physical structure of the Buddha statue body 1 is constructed layer by layer from bottom to top, including: assembling the decorative panel 3 of the layer, laying reinforcing steel bars and reliably connecting them to the panel, and then pouring filling material to form a solid. After each layer is constructed, the solid shape is obtained by three-dimensional scanning and compared with the digital model to dynamically guide the construction of the next layer. The process involves obtaining the physical form through 3D scanning and comparing it with the digital model. Based on the comparison results, processing correction data for each decorative panel 3 in the next layer is generated. This includes: using an iterative nearest point algorithm to accurately register the measured point cloud with the S1 digital model, calculating the 3D coordinate deviation value of each control point, the surface curvature adjustment amount, the fitting error compensation value of the edge connection surface, and the CNC cutting correction parameters corresponding to each panel.

[0023] S6: After the Buddha statue body 1 reaches the design elevation and the filling material reaches the design strength, the backlight 2 unit is installed and fixed to the Buddha statue body 1 through the connection transition structure with three-dimensional adjustment function. S7: Perform overall surface treatment and data testing on the installed Buddha statue body 1 and backlight 2. Specific surface treatments include weld grinding, surface puttying, and finishing processes such as antique painting or gilding.

[0024] Specifically, by implementing three major steps—topology optimization for lightweight backlight 2, three-dimensional adjustable dedicated connection, and layer-by-layer scanning and correction construction—the problems of eccentric load transfer, wind and earthquake resistant connection, and high-precision installation between the main body 1 and backlight 2 of the large Buddha statue are solved, significantly improving the safety and construction controllability of the overall structure.

[0025] To achieve the above construction method, a construction structure for large Buddha statues is also provided. Considering that the backlight 2 of traditional large Buddha statues often uses an integral casting or welded frame, the cumulative errors caused by the layered construction of the main body cannot be adequately compensated for during the installation stage of the backlight 2. This leads to the backlight 2's posture deviating from the design, thus affecting the appearance and structural stress coordination. Figures 3-8 As shown, the construction structure mainly includes: the Buddha statue body 1, the backlight 2, and a special transition connection structure connecting the two.

[0026] Specifically, the Buddha statue body 1 includes a decorative panel 3, a connecting steel structure 4, and a concrete filler. The connecting steel structure 4 and the concrete filler constitute a stable internal structure of the Buddha statue body 1, and the decorative panel 3 is set on the outer surface of the connecting steel structure 4. The backlight 2 consists of a space truss 5 composed of a main load-bearing rod and a secondary stabilizing rod, and a decorative panel 3 installed on the outer surface of the space truss 5; Furthermore, connecting ribs 13 and internal reinforcing ribs 14 are provided between the decorative panels 3 of the Buddha statue body 1 and the backlight 2, which enhances the connection stability between adjacent decorative panels 3, effectively resists out-of-plane deformation of the panels under wind load or temperature action, and improves the rigidity and buckling resistance of the panels themselves.

[0027] In order to provide a certain amount of space compensation when the backlight 2 and the Buddha statue body 1 are installed and aligned, the special transition connection structure includes pre-embedded anchors and three-dimensional adjustment components. Specifically, the pre-embedded anchors include pre-embedded sleeves 6 and mounting plates 7. The pre-embedded sleeves 6 are set in the back area of ​​the Buddha statue body 1, and the mounting plates 7 are set on the side of the backlight 2 close to the Buddha statue body 1. During the assembly of the Buddha statue body 1 and the backlight 2, the pre-embedded sleeves 6 and mounting plates 7 are set in the corresponding positions. The three-dimensional adjustment component includes an adjustment screw 8, a first adjustment plate 9, a second adjustment plate 10, and a locking bolt assembly 11. One end of the adjustment screw 8 is threadedly connected to the pre-embedded sleeve 6, and the other end is fixedly connected to the first adjustment plate 9. The first adjustment plate 9 is provided with a vertically extending vertical elongated hole 901. The end face of the first adjustment plate 9 with the vertical elongated hole 901 corresponds to the second adjustment plate 10. The second adjustment plate 10 is provided with a horizontally extending horizontal elongated hole 1001. The end face of the second adjustment plate 10 with the horizontal elongated hole 1001 corresponds to the mounting plate 7. The vertical elongated hole 901 and the horizontal elongated hole 1001 are arranged in a spatial cross shape. The locking bolt assembly 11 is respectively disposed between the vertical elongated hole 901 and the horizontal elongated hole 1001, and is used to adjust the position of the first adjustment plate 9 and the second adjustment plate 10 in the vertical direction and the position of the second adjustment plate 10 and the mounting plate 7 in the horizontal direction. Specifically, the locking bolt assembly 11 includes a vertical bolt group 1101 and a horizontal bolt group 1102. The vertical bolt group 1101 consists of a bolt passing through the vertical elongated hole 901 and a locking nut. The bolt head or nut abuts against the second adjusting plate 10. By loosening the nut, the second adjusting plate 10 slides up and down along the vertical elongated hole 901 to the desired position and then re-locks it to achieve vertical adjustment. The horizontal bolt assembly 1102 consists of a bolt passing through the horizontal elongated hole 1001 and a locking nut. The bolt shank is fixed to the mounting plate 7. By loosening the nut, the mounting plate 7 can slide left and right along the horizontal elongated hole 1001 to the desired position and then be tightened again to achieve horizontal adjustment. During installation, the direction of the backlight 2 on the Z-axis is controlled by the adjusting screw 8. The distance between the backlight 2 and the Buddha statue body is controlled by adjusting the length of the adjusting screw 8 extending into the pre-embedded sleeve 6. The directions on the X-axis and Y-axis are adjusted by the first adjusting plate 9, the second adjusting plate 10, the mounting plate 7, and the matching vertical bolt group 1101 and horizontal bolt group 1102.

[0028] Furthermore, a ball joint structure 12 is provided between the second adjustment plate 10 and the mounting plate 7. The ball joint structure 12 includes a ball head seat 1201 and a ball head rod 1202. The ball head seat 1201 is fixed on the second adjustment plate 10. One end of the ball head rod 1202 is a ball head and is housed in the ball head seat 1201 to form universal rotation. The other end of the ball head rod 1202 is fixedly connected to the mounting plate 7 to realize a small angle deflection adjustment of the backlight 2 relative to the Buddha statue body 1. After the adjustment is completed, the ball head seat 1201 and the ball head rod 1202 are fixed by locking screws.

[0029] When installing the backlight 2 on site, the actual three-dimensional coordinates of all the pre-embedded sleeves 6 on the back of the Buddha statue body 1 were re-measured and compared with the theoretical model to confirm that the deviation was within the adjustment stroke range of the three-dimensional adjustment component. At the same time, the internal threads of the pre-embedded sleeves 6 were cleaned and anti-seize grease was applied. The adjusting screw 8, the first adjusting plate 9, the second adjusting plate 10, the locking bolt assembly 11 and the ball joint structure 12 are grouped according to the pairing marks of the factory pre-assembly. It is confirmed that each component can be adjusted flexibly. The ball head rod 1202 is pre-installed on the mounting plate 7 of the backlight 2 truss. The ball head of the ball head rod 1202 is inserted into the ball head seat 1201 that has been fixed on the back of the second adjusting plate 10 to form the backlight 2 side transition assembly. The lifting equipment uses a multi-point lifting device to lift the backlight 2 unit in a balanced manner and slowly approach the installation area on the back of the Buddha statue body 1. Then, the threaded end of each adjusting screw 8 is aligned with the corresponding numbered embedded sleeve 6, and two to three turns of thread are manually screwed in so that all adjusting screws 8 evenly bear the weight of the backlight 2, and the backlight 2 is in a suspended and adjustable state. Next, the adjusting screws 8 at each connection point are rotated synchronously. By changing the depth of their screwing into the pre-embedded sleeve 6, the axial distance between the backlight 2 and the back of the Buddha statue body 1 is adjusted evenly, so that the distance between each mounting plate 7 and the second adjusting plate 10 is roughly within the design range and space is reserved for subsequent fine-tuning. After the axial coarse adjustment is completed, the first adjusting plate 9 and the second adjusting plate 10 are placed face to face, so that the vertical elongated hole 901 on the first adjusting plate 9 and the horizontal elongated hole 1001 on the second adjusting plate 10 are arranged in a cross shape. The high-strength bolts of the vertical bolt group 1101 are inserted through the vertical elongated hole 901 from the side of the first adjusting plate 9. After the shims are put on the side of the second adjusting plate 10, the locking nuts are initially tightened by hand. The locking nuts are slightly loosened. The second adjusting plate 10 is pushed by the hydraulic jacking device so that it slides up and down along the vertical elongated hole 901 on the first adjusting plate 9, thereby driving the backlight 2 to rise and fall as a whole. The elevation of the key control points of the backlight 2 is monitored in real time with a laser level. After confirming that the vertical position deviation is within the allowable range, the locking nuts of all the vertical bolt groups 1101 are tightened diagonally in sequence. Then, the mounting plate 7, which is connected to the second adjusting plate 10 by ball head rod 1202 and ball head seat 1201, is attached to the end face of the second adjusting plate 10 with horizontal elongated hole 1001. The high-strength bolt of the horizontal bolt group 1102 is inserted and the locking nut is screwed on for initial pre-tightening. After slightly loosening, the mounting plate 7 is pushed to slide left and right along the horizontal elongated hole 1001 on the second adjusting plate 10, causing the backlight 2 to move horizontally as a whole. The horizontal offset of the control points on the top and sides of the backlight 2 is monitored with a total station. After confirming that the deviation is within the allowable range, the locking nuts of all horizontal bolt groups 1102 are tightened diagonally in sequence. After the vertical and horizontal directions are in place, loosen the side locking screws of the ball head seat 1201, and finely adjust the overall posture of the backlight 2 with a pry bar. Use the universal rotation function of the ball joint structure 12 to compensate for the pitch, sway and torsion angle deviation of the backlight 2 relative to the Buddha statue body 1. The adjustment range is ±3° to ±5°. Use a total station to collect the coordinates of multiple control points of the outer contour of the backlight 2 and compare them with the digital model. After confirming that the spatial posture deviation is within the design allowable range, tighten the side locking screws of the ball head seat 1201 to press and fix the ball head. Finally, the locking nuts of all vertical bolt groups 1101 and horizontal bolt groups 1102 are tightened to final torque and anti-loosening pins are installed. Locking glue is applied to the exposed threads of all threaded fasteners. Locking glue is also applied to the threaded joint between the adjusting screw 8 and the embedded sleeve 6. After removing the lifting tools, a 3D scanner is used to scan the backlight 2 as a whole and the connection nodes. The point cloud data is compared with the design model to generate an installation accuracy report. After confirming that it is qualified, the installation is completed and accepted.

[0030] In summary, this construction structure addresses the pain points of traditional construction, such as the large weight of the backlight and the difficulty in controlling installation accuracy. By designing the backlight 2 as a lightweight spatial truss frame 5, pre-embedding high-strength connection nodes on the back of the Buddha statue body 1, and adopting a special transition connection structure with three-dimensional adjustment function, a stable connection and reliable load transfer between the backlight 2 and the Buddha statue body 1 are achieved, thereby improving the overall structure's wind resistance, earthquake resistance, and long-term stability.
