Sports wooden floor is a special paving material for the ground in various basketball courts, badminton halls, volleyball halls and sports centers. How to choose sports wood floor?
First, the main material selection of sports wood floor
The main materials of sports wood floor include wood floor surface layer, raw floor layer, keel (shelf), auxiliary keel, pad and so on. In addition to the bamboo floor, the surface material should have good elasticity, strength and hardness and beautiful patterns; the raw floor, keel, auxiliary keel, etc. should have good corrosion resistance, nail holding force and impact resistance.
Second, the choice of surface material
1. Material species. The main species of sports wood floor surface material are maple, oak, beech, pine, ash and so on.
2. Appearance quality. It should meet the requirements of the first-class product in Table 1 of GB/T15036.1-2001 "Technical Conditions for Solid Wood Flooring"

3. Specifications and dimensions. Length ≥300mmv width 50~150mm, thickness 22, 24mm. According to experience, generally the length of solid wood floor is an integer multiple of the main keel spacing, so that the joint can fall on the main keel during paving; the width of solid wood floor should be narrow rather than wide. Specifications and dimensions can also be determined by negotiation between the supplier and the buyer.
4. Machining accuracy. It should meet the requirements of Table 2 in GB/T 15036.1-2001, the absolute value of the difference between the nominal thickness and the average thickness of the unpainted floor is ≤ 0.3m, and the difference between the maximum and minimum thickness is ≤ 0.4mm.

Three, fur floor, keel layer material selection
Selection of fur floor layer, keel and auxiliary keel material The selection of fur floor layer, keel and auxiliary keel material is mainly based on the cell structure of tree species and the physical and mechanical indicators of wood. The research shows that: the larch of the land and the larch of Xing'an are superior to the Korean pine, the white pine and the stinky fir in the resin canal content, flexural strength, flexural modulus, transverse grain compressive strength, impact toughness and hardness. The first choice for the fur floor, keel and auxiliary keel of the wooden floor is Xing'an larch and Landrace larch. Its quality grade must meet the requirements of first-class timber in GB/T 153-1995 "Coniferous Sawn Timber".
