Connection design
- Embedded Design:
- Special embedding grooves can be designed at the end of the artificial bamboo, and the metal connectors are made into matching shapes, such as T-shaped or L-shaped projections. In this way, when installing, the metal connector can be closely embedded in the artificial bamboo, increasing the contact area and thus improving the strength of the connection. For example, for the artificial bamboo with diagonal support structure, at the end connected with the crossbar or column, a square groove of suitable depth can be dug inside the bamboo material, and one end of the metal connector is made into a square projection, which will be inserted into the groove when installing, and further fixed with glue or screws.
- Wrap-around design:
- Designing metal connectors in the form of a ring around the artificial bamboo. For example, use metal hoops to secure the artificial bamboo to other structural components. The metal hoop can be semi-circular or C-shaped and is tightened by bolts or clips to hold the bamboo tightly. In this way, the stress in the connection area can be evenly distributed, avoiding the concentration of stress that may lead to loosening or damage of the connection. At the same time, in order to prevent the artificial bamboo from sliding inside the metal hoop, some non-slip textures or bumps can be designed on the surface of the artificial bamboo where it comes into contact with the metal hoop.
Material surface treatment
- Artificial bamboo surface pretreatment:
- Sand or chemically treat the joining surface of artificial bamboo to increase its roughness. Sandpaper can be used to create tiny pits and bumps in the surface so that it will embed and bite better when combined with metal connectors. Alternatively, chemical etching can be used to create some microscopic textures on the surface of the artificial bamboo to enhance the friction with the metal.
- Surface treatment of metal connectors:
- Coating the surface of metal connectors, such as galvanizing and painting, prevents the metal from rusting and corroding. Rusted metal connectors will swell and flake, affecting the strength of the connection. In addition, a layer of bonding accelerator can be coated on the surface of the metal connectors. This chemical substance can enhance the bonding strength between metal and artificial bamboo, especially when glue is used for the connection, the bonding accelerator can significantly improve the bonding effect of the glue.
reinforcement
- glue：
- Choosing the right glue is critical to ensuring the strength of the joint. High-performance structural glues, such as epoxy resin glues, can be used. This type of glue is characterized by high strength, aging resistance and good water resistance. When using glue, make sure that the connection surface is clean, dry and that the glue is applied evenly to fill the gaps between the artificial bamboo and metal connectors. After pasting the two, you can use a jig to fix them for a period of time to ensure that the glue is fully cured to achieve the best bonding effect.
- Mechanical fixation:
- In addition to glue bonding, the strength of the connection can be further enhanced in conjunction with mechanical fixing methods. For example, use screws or bolts for reinforcement on the basis of embedded or ring-type connections. Pre-drill holes in artificial bamboo and metal connections, taking care that the size of the holes matches the screws or bolts to avoid being too large or too small. The material of the screws or bolts should be corrosion-resistant stainless steel, and they should be tightened when installing, so that the metal connectors and the artificial bamboo are tightly fixed together.
