playing field Wood floor High use intensity, complex technical performance requirements, Tianjiao sports special use wood floor In strict accordance with the People's Republic of China
GB/T19995.2 — two thousand and five National Standards and All Sports Ground Science Society（ IST ）Design, production, installation, construction, warranty and service.
Wooden floor of playground Function introduction:
motor function
In order to meet the sports requirements for amateur or professional use, Tianjiao sports wood floor meets DIN18032 The standard tests six motion parameters, namely, motion buffer, ball rebound, motion friction, static load, motion load and floor fatigue performance test.
l Shock absorption (motion cushioning) KA/% ≥ fifty-three
l Ball bounce rate (ball bounce) BR/% ≥ ninety
l Rolling load (floor relieves fatigue) VRL/N ≥ 1 500
l Coefficient of motion friction / μ 0.4~0.6
l Standard vertical deformation (moving load) StVv/mm ≥ two point three
l Vertical deformation rate (static load) W500/% ≤ fifteen
Protection function
The impulse formed by people during exercise will produce vibration on the wooden floor plane, that is, when athletes jump back to the wooden floor, they must have 53H The above impulse is absorbed by the wood floor. Tianjiao sports wood floor adopts multi-layer shock absorption and overhead structure, which has good functions of shock absorption, shock deformation and extension deformation, thus playing the role of protecting people's ankle joint, meniscus, spine and brain, so that people will not be injured during sports. At the same time, the movement of a single person on the wooden floor will not affect the adjacent people.
Selected Canadian imports Maple It is a commonly used tree species in all competitions, with moderate hardness, slight deformation, and is not easy to prick, so as to avoid injury to athletes' appearance.
Selection MFMA Recognize the high molecular moisture abrasion resistant paint imported from Baodao, three times of polishing and three times of polishing from coarse to fine Topcoat Process, good slip characteristics, consistent with MFMA and DIN The standard friction coefficient, which is not slippery and astringent, also plays an important role in ensuring the stability of athletes.
Technical functions
There is a big difference between the wooden floor for stadiums and stadiums and the wooden floor for civil use. Its load-bearing load and solid curing service life must meet the requirements of competition and training. For example, when the movable basketball stands and related sports facilities move on the wooden floor, the surface and structure of the wooden floor cannot be damaged. Therefore, the floor structure is complex and has many layers, The requirements for physical and mechanical properties of materials are high.
Tianjiao sports wood floor unique not lower than thirteen The construction process and hierarchical structure are adopted with super wear-resistant water-based finish imported from Baodao, With superior Wear resistance, strong pollution resistance , no missing The surface is not blistered, its quality can withstand thousands of hours of use without damage, and the color difference is strictly controlled from the consideration of avoiding reflection. The substructure includes high quality Wooden keel , with special DIN The standard elastic pad can produce superior elasticity and improve the overall comfort of the wooden floor. Water pipes, electric wires and other service facilities can be allowed to be laid at the gap of wooden keel.
The service life of the wooden floor is closely related to the waterproof treatment of the wooden floor system. Tianjiao sports wooden floor system adopts all professional waterproof treatment systems, including the waterproof and moisture-proof treatment of foundation, cement pier, exposed objects and plywood; The keel is chrome copper arsenic（ CCA ）And Wood Life Pressure anti-corrosion and moisture-proof treatment.
Tianjiao sports wood floor system shall be no less than seven The process of termite prevention treatment is a meticulous and integrated protection and prevention process for the wooden floor system, which can greatly extend the service life of the wooden floor system.
