They are often used in projects such as ancient building restoration, rural residences, and holiday villas. However, traditional brick-wood structure construction nodes often have problems such as loose connections, poor moisture and corrosion resistance, and insufficient earthquake resistance. These problems limit the widespread application of brick-wood structures in modern buildings. For example: 1. Traditional brick-wood structures are usually connected by simple mortise and tenon joints or nails. These joints are prone to loosening or breaking when subjected to stress, resulting in insufficient structural stability. In particular, brick-wood structures are prone to serious damage when natural disasters such as earthquakes occur. 2. The wood part of the brick-wood structure is easily affected by moisture and corrosion, which causes the wood strength to decrease, thus threatening the safety of the entire structure. Traditional moisture-proof and anti-corrosion measures are often ineffective, and the construction is complicated, making it difficult to guarantee long-term protective effects.

[0029] This embodiment also provides a construction method for constructing the above-mentioned building brick-wood structure construction node, which specifically includes the following steps: S1.

[0031] Working principle: When the wooden embedded part 3 is connected to the wood in the present application, the surface of the embedded column 30 of the wooden embedded part 3 has a barb-like protrusion 31, and the inclination angle is 30-60 degrees. When the embedded column 30 is inserted into the circular groove pre-processed at the end of the wood node 2, the barb-like protrusion 31 will be tightly engaged with the wood. At the same time, the wood adhesive coated on the column surface will form a bonding force between the embedded column 30 and the wood, further enhancing the stability of the connection. This combination of mechanical engagement and chemical bonding can effectively prevent the embedded column 30 from loosening or pulling out in the wood, ensuring the reliability of the connection between the connector and the wood. When the brick masonry connection part 4 is connected to the brick masonry 1, the serrated tip protrusion 41 on the surface of the connection column 40 of the brick masonry connection part 4 is adapted to the mortar joint structure on the surface of the brick masonry 1, and the bite depth is ≥5mm. During installation, the connection column 40 is placed in the installation space 8 reserved for the brick masonry 1, and the tip protrusion 41 is embedded in the mortar joint, just like the mortise and tenon structure, so that the connection column 40 and the brick masonry 1 can be effectively limited and fixed in the horizontal and vertical directions. The high-strength bonding mortar 9 filled in the installation space 8 can not only fill the groove 42 on the surface of the connection column 40 after solidification, but also can be tightly bonded with the brick masonry 1 and the connection column 40 to form a whole, firmly anchoring the connector in the brick masonry 1, and bearing forces from all directions, including tension, pressure and shear, etc., so as to ensure that the connection strength at the brick-wood structure node meets the requirements of the building structure; The asphalt-impregnated linen layer 5 surrounds the outer surface of the wood node 2 and the connecting column 40, with a thickness of 3-5 mm. The asphalt impregnation depth is not less than 50% of the linen thickness. The asphalt has good waterproof performance and can effectively prevent the intrusion of external moisture. The linen plays a role of reinforcement and buffering, and at the same time provides an adhesion basis for the asphalt. The combination of the two forms a barrier to prevent moisture from penetrating into the wood and the connecting parts, avoiding problems such as wood decay and rust corrosion of the connecting parts due to a humid environment; The polymer coating 6 is an epoxy resin-based or acrylate-based polymer coating 6 to which preservatives and antimicrobial agents are added, and has a thickness of 2-3 mm. The epoxy resin-based or acrylate-based polymer itself has certain chemical stability and weather resistance, and can resist the erosion of the external environment to a certain extent. The preservatives such as organic tin compounds and isothiazolinones added to the coating can inhibit the growth and reproduction of microorganisms such as fungi and bacteria on the surface of wood and connectors, prevent wood decay and biodegradation of connectors, and antimicrobial ingredients such as silver ion antimicrobial agents and quaternary ammonium salt antimicrobial agents can further kill or inhibit the activity of microorganisms, thereby extending the service life of wood and connectors, ensuring that the entire brick-wood structure node maintains structural integrity and stability during long-term use, and can effectively play a moisture-proof and anti-corrosion role even in humid, dark and other environmental conditions that are prone to the growth of microorganisms; The metal wire mesh layer 7 is made of galvanized iron wire, the thickness of the galvanized layer is ≥8μm, the aperture is 5-10mm, and the wire diameter is 1-2mm. The galvanized layer can improve the corrosion resistance of the metal wire mesh and prevent the metal wire mesh from rusting in humid air. The metal wire mesh is wrapped on the outside of the polymer coating 6. On the one hand, it can protect the internal moisture-proof and anti-corrosion materials from being damaged by external collisions, scratches, etc. On the other hand, its mesh structure can disperse the stress applied by the outside to a certain extent, reduce the possibility of damage to the moisture-proof and anti-corrosion layer due to excessive local force, further enhance the durability and reliability of the entire moisture-proof and anti-corrosion system, and provide lasting protection for the brick-wood structure nodes; The triangular support frame 10 is hollow and made of Q235 carbon structural steel with a thickness of not less than 3mm. The triangular structure has good mechanical stability and can effectively resist deformation under external force. One end of the triangular support frame is connected to the wood node 2 by bolts, and the other end is connected by anchor bolts 11 pre-buried in the brickwork 1 to form a stable triangular support system. When external forces such as earthquakes act, the triangular support frame 10 can connect the wood and brickwork 1 into a whole, and cooperate with the force to avoid structural damage due to relative displacement between the two. The connection method of bolts and anchor bolts 11 can reliably transmit force, ensure the tightness and stability of the connection, and enable the triangular support frame 10 to fully play its earthquake-resistant role in the structure. The interior of the triangular support frame 10 is filled with damping particles 13 with a volume ratio of rubber particles to polyurethane foam of 1:2-1:3. When the structure is subjected to earthquake force or other vibration loads, these damping particles 13 will deform and rub, and part of the vibration energy will be converted into other forms of energy such as heat energy and consumed, thereby playing a role in shock absorption and buffering, reducing the vibration amplitude and vibration time of the structure, and reducing the risk of fatigue damage or destruction of the structure due to vibration, further improving the safety and stability of the brick-wood structure of the building in the event of disasters such as earthquakes, and protecting the integrity of the entire building structure and the safety of life and property of the residents; In summary, the building brick-wood structure construction node and construction method of the present invention can effectively realize the connection, moisture-proof, anti-corrosion and earthquake-resistant strengthening functions of the brick-wood structure node under different material and parameter combinations, and ensure the stability and durability of the structure.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
