Considering The Performance Of The Materials Used In The Design Of Outdoor Plastic Wood Pavilions

Plastic wood pavilions are now an important option for many parks, municipalities and scenic spots, and they have excellent performance. For example, the texture similar to solid wood, the adjustable color performance, and the maintenance-free use makes the plastic wood pavilion greatly exceed the ordinary anticorrosive wood pavilion or carbonized wood pavilion. Therefore, the plastic wood pavilion is also favored by many outdoor landscape design engineers.

As a new composite material, the plastic wood pavilion should be fully understood when it is designed for use in the pavilion. As a product with a design life of ten years, it should be firm, durable and beautiful.

1. Plastic wood material is basically a decorative material at this stage, and its performance has not yet reached the category of structural materials, which is quite different from solid wood materials. This is because although plastic-wood composite materials are mainly made of wood flour, the wood fibers in them exist in the form of short fibers during the production process, which is different from the continuous growth of long fibers of solid wood materials.

2. Therefore, the load-bearing and structural parts of the plastic wood pavilion are often reinforced with steel. The strength of steel is high, but the human touch and sensory feel are poor. It is necessary to design hiding from the design source to hide the traces of steel as much as possible and reduce the poor human touch.

3. Considering that the expansion coefficient of plastic-wood profiles is in the same order of magnitude as that of plastic products, and an order of magnitude difference from that of metal steel, sufficient space should be reserved during the design to allow the plastic-wood profiles to expand and contract when the temperature changes. .

4. Considering that the plastic-wood profiles such as the columns, beams, and small beams of the plastic-wood pavilion mainly play the role of covering the appearance of the steel and the transitional connection, the transition mode should be designed at each junction, and the transitional connection is usually designed to be most convenient firm.

5. Considering the composition method of the plastic wood pavilion, the connection with the ground part should be strengthened. The underground concrete layer should be C25 grade, the thickness should be more than 25 cm, and the embedded parts should be used for connection.

In short, it is necessary to fully consider the basic properties of various materials in order to design a good plastic wood pavilion scheme from the source.
