[0028] Example:
[0029] like Figure 1-4As shown, this embodiment proposes a glued laminated timber mesh shell energy-dissipating node structure, including a steel connector 1. Six metal connectors 2 arranged at equal angles around the circumference are fixedly installed on the outer surface of the steel connector 1. The metal connectors 2 are welded to the steel connector 1 to ensure connection strength and improve the overall stability of the node. The metal connectors 2 have mounting grooves 3. Each of the two inner surfaces of the mounting grooves 3 has several V-shaped teeth 4 arranged linearly and equidistantly. Glued laminated timber 5 is inserted inside the mounting grooves 3. Each of the two inner surfaces of the glued laminated timber 5 has several V-shaped grooves 6 arranged linearly and equidistantly. The outer surface of the glued laminated timber 5 is in contact with the inner surface of the mounting grooves 3. The V-shaped grooves 6 and V-shaped teeth 4 are adapted to each other. Several V-shaped teeth 4 are respectively inserted into several V-shaped grooves 6. The glued laminated timber 5 is engaged through the mounting grooves 3 on the metal connectors 2. The adaptation of the V-shaped teeth 4 and V-shaped grooves 6 increases the connection between the glued laminated timber 5 and the metal connector. The contact area and friction between the two parts effectively improve the shear resistance of the connection. The metal connector 2 has two threaded bolts 7 for fixing the glued laminated timber 5. The glued laminated timber 5 is further fixed by the connecting bolts 7 to ensure the stability of the connection between the glued laminated timber 5 and the metal connector 2. Six first mounting blocks 8 are fixedly installed on the outer surface of the steel connector 1 in a circular and equidistant arrangement. Second mounting blocks 9 are fixedly installed on the outer surface of the glued laminated timber 5. A viscoelastic damper 10 is hinged between the first mounting blocks 8 and the second mounting blocks 9. When the structure is deformed by load, the first mounting blocks 8 and the second mounting blocks 9 drive the viscoelastic damper 10 to deform. The viscoelastic damper 10 is made of multiple layers of viscoelastic material and constraint steel plate alternately stacked. It uses the shear deformation of the viscoelastic material to dissipate energy and improve the energy dissipation capacity of the node. The cross-section of the steel connector 1 is hexagonal, and the six viscoelastic dampers 10 are arranged in a circular and equidistant arrangement.
[0030] like Figure 1 and Figure 4 As shown, the steel connector 1 has a vertically penetrating hexagonal prism groove 11. Inside the hexagonal prism groove 11, there are several vertically equidistant reinforcing members 12. Each reinforcing member 12 includes a connecting block 13 and several connecting rods 14. The connecting rods 14 are fixedly connected to the connecting block 13. The several connecting rods 14 are arranged at equal angles around the circumference. The end of the connecting rod 14 away from the connecting block 13 is fixedly connected to the inner wall of the hexagonal prism groove 11. Both the connecting block 13 and the connecting rods 14 are made of alloy steel, which has high strength and good toughness. The multiple reinforcing members 12 inside the hexagonal prism groove 1 can enhance the rigidity and strength of the steel connector 1 and improve its resistance to deformation.
[0031] like Figure 1 , Figure 2 and Figure 3As shown, the V-shaped tooth 4 and the metal connector 2 are integrally formed. The length of the glued laminated timber 5 is greater than the length of the steel connector 1. The V-shaped groove 6 has the same length as the V-shaped tooth 4. By adapting the V-shaped tooth 4 and the V-shaped groove 6, the contact area and friction between the glued laminated timber 5 and the metal connector 2 can be increased, effectively improving the shear resistance of the connection.
[0032] The working principle of the above embodiment is as follows: The glulam 5 is engaged with the mounting slot 3 on the metal connector 2. The V-shaped teeth 4 and V-shaped grooves 6 are adapted to increase the contact area and friction between the glulam 5 and the metal connector 2, effectively improving the shear resistance of the connection. The glulam 5 is further fixed by the connecting bolts 7 to ensure the stability of the connection between the glulam 5 and the metal connector 2. The stiffness and strength of the steel connector 1 are enhanced by the multiple reinforcing parts 12 inside the hexagonal prism groove 11. When the structure is deformed by load, the first mounting block 8 and the second mounting block 9 drive the viscoelastic damper 10 to deform. The viscoelastic damper 10 is made of multiple layers of viscoelastic material and constrained steel plates, which dissipate energy by shear deformation of viscoelastic material and improve the energy dissipation capacity of the node. The metal connector 2 and the steel connector 1 are welded to ensure the connection strength. Through the synergistic effect of multiple structures, the energy dissipation, connection reliability and mechanical properties of the node can be effectively improved, so that it can better bear the load and ensure the safety and durability of the structure.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
