[0015] A construction method for antique building woodwork, comprising the following steps: S1. Use a steel light frame and prefabricated wood components to form a steel-wood composite structure as the main load-bearing frame; the present invention uses a steel-wood composite structure as the main load-bearing frame of the antique building. Specifically, a light steel frame is used inside, and prefabricated wood components are covered on the outside. The steel frame is made of high-strength lightweight steel, and the load requirements and structural characteristics of the building must be considered during the design. Prefabricated wood components use high-performance glued wood (such as laminated veneer LVL or cross-laminated timber CLT), and CNC machining is used to achieve precise production of complex mortise and tenon joints. During the construction process, the steel frame and wood components are first prefabricated in the factory, and then assembled on site to ensure the accuracy and quality of the structure; S2. Carbon fiber reinforced materials are embedded in the brackets and cantilevered eaves according to the predetermined design to improve the local bending and shearing performance. In order to improve the bending and shearing performance of the structure at key locations, carbon fiber reinforced materials are embedded in easily stressed locations such as brackets and cantilevered eaves. The specific method is: grooves are made at the corresponding positions of the prefabricated wood components, and the pre-cut carbon fiber sheets are embedded in the grooves, and epoxy resin is used to bond and fix them. After bonding, curing treatment is performed to ensure the close combination of carbon fiber and wood, thereby improving local strength. S3. Use BIM technology to perform parametric modeling on complex wooden components, and optimize the node connection design accordingly. After prefabricating each component in the factory, assemble it on site; In the present invention, building information modeling (BIM) technology is used to perform parametric modeling on complex wooden components. First, use professional BIM software (such as Revit) to build a three-dimensional model of the building, and accurately design the size, shape and connection method of each component. Through parametric modeling, the design plan can be quickly adjusted and the node connection design can be optimized. After the design is completed, construction drawings and processing data are generated to guide the factory to perform prefabrication processing. During on-site construction, use the BIM model for guidance to ensure the accurate installation of each component; S4. The reverse construction method is used to construct the eaves and roof cantilever structures. The construction sequence is: first install the roof tiles and awnings, then fix the rafters. At the same time, a standardized modular temporary support system with integrated stress and displacement sensing functions is used, and the construction process is simulated and optimized in combination with BIM and digital twin technology to ensure construction safety.

[0016] For cantilevered eaves and roof structures, the reverse construction process is used. The specific steps are as follows: 1. Installation of roof tiles and lookout boards: First, pre-assemble the roof tiles and lookout boards on the ground to form an integral roof unit.

[0017] 2. Construction of temporary support system: Build a standardized, modular and adjustable temporary support system below the installation location to ensure safety and stability during the construction process.

[0018] 3. Lifting and fixing of roof unit: Use lifting equipment to lift the pre-installed roof unit to the designed position and fix it to the cantilevered part of the steel-wood composite structure.

[0019] 4. Installation of rafters: After the roof unit is fixed, install the rafters and connect them firmly to the roof structure.

[0020] 5. Removal of temporary support: After ensuring the stability of the structure, remove the temporary support system.

[0021] 6. During the construction process, the stress state of the support system is simulated and dynamically adjusted through BIM and digital twin technology to ensure construction safety.

[0022] S5. At the key nodes of column heads and beam ends, a combined connection method of steel components and wooden components is adopted, which are fixed by bolt anchoring and epoxy resin bonding respectively, and strain gauges, vibration sensors, and temperature and humidity sensors are set inside the nodes to implement real-time monitoring of the stress state of the nodes; At key nodes such as column heads and beam ends, a combined connection method of steel components and wooden components is adopted. The specific method is: connecting plates are set at the corresponding positions of the steel skeleton, and corresponding connection holes are reserved on the prefabricated wooden components. During installation, align the wooden components with the steel components, anchor them with high-strength bolts, and apply epoxy resin adhesive on the contact surface to enhance the firmness of the connection. In addition, strain gauges, vibration sensors, and temperature and humidity sensors are embedded inside the key nodes to monitor the stress and environmental conditions of the structure in real time. The data collected by the sensors are transmitted wirelessly to the monitoring system to facilitate the assessment and maintenance of the structural health; S6. Use magnetic mortise and tenon connection technology to achieve non-destructive disassembly of components, and set mechanical clips at the connection parts to achieve auxiliary locking. At the same time, implement redundant design of the connection structure to ensure long-term reliability. In order to achieve non-destructive disassembly and reuse of components, magnetic mortise and tenon connection technology is adopted. The specific design is: permanent magnets are embedded in the corresponding positions of the tenon and the mortise respectively to ensure that the mortise and tenon connection can be quickly connected and separated by magnetic force. In addition, on the basis of magnetic adsorption, a mechanical clip device is added to provide additional mechanical locking to ensure the stability of the node connection. When disassembly is required, use special tools to release the mechanical lock, and use the characteristics of magnetic adsorption to achieve non-destructive disassembly of components.

[0023] The steel-wood composite structure in step S1 includes: a steel core frame and prefabricated wood components, wherein the prefabricated wood components completely cover the steel core frame; steel tie rods are arranged at the bracket layer according to design requirements; and a triangular support structure composed of steel diagonal braces and wood components is arranged at the cantilevered eaves.

[0024] The node connection design in step S3 includes: a combination of a detachable mortise and tenon structure and a bolt connection structure; an intelligent monitoring sensor is provided at the node position for real-time collection of node stress and vibration data; a redundant connection design is adopted inside the node, and when a single connection fails, the overall stability of the node can still be maintained.

[0025] The reverse construction in step S4 includes: installing roof tiles and fascia boards first in order at the beginning of construction, and then fixing rafters; using a standardized, modular and adjustable temporary support system during the construction process, each module of which is preset with stress sensors and displacement sensors, and using BIM and digital twin technology to simulate and dynamically adjust the stress state of the support system.

[0026] The non-destructive disassembly in step S6 includes: Magnetic mortise and tenon structure, in which specially designed tenons and mortise joints are provided with permanent magnets, and the connection and separation between components are achieved through magnetic force; A mechanical snap-on structure is used to assist in locking the node after magnetic adsorption; Redundancy design is implemented in the node connection structure to ensure that the connection remains stable when any single connection fails.

The prefabricated wood component uses high-performance glued wood, such as laminated veneer (LVL) or cross-laminated timber (CLT). During the production process, firstly, high-quality wood is selected and dried to ensure that the moisture content meets the requirements. Then, the wood is cut according to the designed size and laminated with an environmentally friendly adhesive to form the required board. The board is precisely processed by CNC processing equipment to produce complex mortise and tenon joints. For composite material components that require a wood-like effect, lightweight high-strength concrete can be used for prefabrication. The wood grain texture is engraved on the inner surface of the mold, and after pouring concrete, a wood-like effect is formed on the surface. After the component is cured, the surface is treated and antique paint is applied to achieve a fake-like effect.

[0028] Carbon fiber reinforced materials are embedded in stress-prone locations according to design requirements to improve local structural strength, and lightweight and high-strength roof panels are used to lay the roof to reduce its own weight.

[0029] In order to reduce the weight of the roof and improve the structural performance, the present invention uses lightweight and high-strength roof panels, such as cross-laminated timber (CLT) panels, in the roof construction. The specific steps are as follows: Material preparation: Select CLT panels that have been dried and meet design requirements to ensure they have sufficient strength and durability.

[0030] Size cutting: According to the roof design drawings, the CLT panels are accurately cut to ensure that the size is consistent with the design.

[0031] Protective treatment: Apply waterproof coating on the surface of CLT board to enhance its waterproof performance and prevent it from getting damp or damaged during use.

[0032] Installation and laying: Lay the processed CLT panels on the roof structure according to the design requirements, ensuring that the panels are tightly connected and have no gaps.

[0033] Fixed connection: Use special connectors or bolts to fix the CLT board to the roof structure to ensure its stability and safety.

[0034] Subsequent processing: Lay the waterproof layer and roof tiles on the CLT board to complete the overall construction of the roof.
