Wood Athletic Flooring
Wood athletic flooring introduction
Wood athletic flooring function :
In the selection of indoor sportsground materials, unique sports flooring has irreplaceable .Because PU(plastic), PVC, silicon PU and other floors provide a little flexibility, whilethe sports wood floor is provided with a surface elasticity. Although someelastic material can also be used in the sports field, it hinders the rapidmovement, which makes the athlete feel as if the foot is stuck on the floor.The motion wood floor system provides the surface elasticity, can guarantee thebest movement freedom, is the first choice for the indoor sports ground material.
PVC, PU and other ground stress (point elasticity)
Moving wood floor surface stress (surface elasticity)
Structure:
Wood Athletic Flooring is wood floor structure system with sport andprotection function.
The structure type of the internationalsports wood floor system is preferred.
Fixed installation process in ensuring the performance of movement(ball bounce rate), at the same time, reduce the protective function ofathletes, so that athletes of the knee, hip and other parts easily damaged.Moreover , because of the large deformation of the wood athletic flooring andthe cement base , under the long-term fluctuation of humidity and temperature,the structure of the wood floor is easy to cause the problems of arch, crackand so on. the suspension type installation process can better overcome theseproblem

| Relative vertical deformation (W500) | Lateral deformation coefficient of the test floor, tension is to examine floor structure important standards, require the center point in the vertical ran from floor deformation of 500m ≤ 15%. |
| Standard vertical deformation | Vertical deformation of the test floor, requiring a point when a certain momentum in the vertical, vertical deformations of the floor must be ≥ 2.3mm. The index passed the test floor elasticity and tension, and users safe. |
| Rolling load (VRL) | Elastic recovery tests flooring, flooring in a high density after use, keep the surface smooth, no dents. Requirements to 1500N continuous rolling ground, surfaces are not damaged. Guarantee the durability of the floor, expanding the range of venues, while reducing maintenance costs. |
| Surface friction (GV) | Test floor surface coefficient of friction, international standards for the 0.4-0.60. The index affects the mobilization activities and security. |
| Impact absorption(KA) | The floor is the most important-absorption test movement momentum, forming a buffer to avoid athletes floor damage caused by ground reaction force. Index momentum absorbing ≥ 53%. |
| Ball bounce(BR) | Basketball rebound height is at least in the sports flooring cement 90%. The position and intensity of the indicator when it comes to dribbling master, to meet the fast-paced demands of the movement. |

Exterior :
The appearanceshall conform to the relevant requirements of the national standard GB50209"construction quality acceptance specification for construction groundengineering" in the third chapter and the sixth chapter. The seam width,surface flatness, surface seam adjacent plate height, surface opening projectdeviation should be allowed to meet the GB50209 "code for acceptance ofconstruction quality of building ground" in the provisions of 7.1.7.
Smoothing :
Paving good wood floor surface,with 2M by the ruler measurement , flatness should not be more than 2mm; theoverall level of the site. Two randomly selected 15m in the range of themeasurement with the elevation , height should be less than 15mm.
Coating function :
The color of the coating does not affect theconfirmation of the drawing line of the field area, and the reflection of thepaint should not affect the exertion of the athletes, and has thecharacteristics of wear resistance, non slip, and difficult to burn.
Ventilation equipment :
Sports floor structure should have ventilationfacilities, not only can play a good ventilation, but also the layout isreasonable, can not be set in the game area, its color and surface layer of thesame or similar.
Measure ofdistortion protection:
The surface layer should take anti deformationmeasures to avoid the influence of the floor due to the external environmentchanges and the normal use of the up and down concave and other deformation.

Materials :
SUPPER WOOD ：Thespecification of 30*50mm LVL composite wood keel, the quality of the productscomply with the relevant requirements of "GB/T20241-2006" of the LVL..
LVL materials with high strength and toughness, good stability, precisespecifications, solid wood than in strength and toughness improved a lot. LVLcompared with solid wood material, LVL has many advantages that ordinary solidwood has wood:
LVL material can log scar section, cracks and other defects scattered,staggered, so as to reduce the influence of strength, its quality andstability, strength uniform, material variability.
LVL has insect resistant, anticorrosive, waterproof, fireproofperformance, mainly in the production process of the corresponding pretreatmentor the special adhesive. Is the most ideal structure of solid wood material,LVL has a strong seismic performance and damping performance, and can resistthe generation of periodic stress fatigue damage.
Backing plate：Made of pineplywood, specifications 12*1220*2440mm, environmental standards to achieve theE1 level, the quality of the products comply with the relevant requirements ofthe "GB/T17657-1999" panel.
Sport woodflooring ：The material is a class of northeast maple flooring orimported maple flooring.
Maple floor two, board aspecification of 22*60/65*300-1000mm, at the construction site after thecompletion of pavement, and then polishing paint, longer duration. Another kindof specifications for 22*120*1800mm double finger paint board, unified to paintin the processing workshop, on-site installation is finished, without polishpaint, improve the work efficiency.
Maple flooring should be in thefield of Polish paint, specifications for 22*60/65*300-1000mm.
The product quality is inaccordance with the relevant requirements of GB/T20239-2006 "wooden floorfor sports facilities".
Damping cushions ：Choose sports wood floor specialred silica gel mat, the specification is 10*20*80mm. Shore hardness of 50degrees, in accordance with the requirements of the specification of thisproduct hardness 50-70.
Floor brad：The L50 specialwooden floor antiskid nail surface notch processing, can effectively preventthe loosening. When installed into the inside of the keel, keel, wooden floorplate, the surface layer structure of each layer are closely connected. The useof imported professional sports flooring installation of high pressure steam.
