Sports wood floor
I. Classification by purpose
1. Sports flooring for training, teaching and fitness: It is mainly used in athletes' training, teaching and fitness occasions with low performance index. Its impulse absorption rate and standard vertical deformation index are lower than those of sports flooring for competition, which are ≥35% and ≥ 1.0mm respectively, mainly considering the construction cost.
2. Sports wooden floor for competition is used to undertake high-level competitive competitions (Olympic Games, World Championships, World Cup, etc.). ) In the indoor gym. The intensity of the competition is high, and there are requirements for the technical indicators of the sports wooden floor, such as basketball and handball. Its main performance indexes are impact absorption rate and standard vertical deformation ≥53% and ≥2.3mm respectively.
Sports wood floor
Second, according to the structural form of classification
Different uses and structural forms of sports wood flooring have different cost and performance indicators, so the structural forms of sports wood flooring are mainly divided into single-layer, double-layer and double-layer composite structural forms.
1. Single-layer structure sports wood floor: Also known as economical structure sports wood floor, it is mainly laid on the floor of indoor gymnasium by surface floor and keel floor or only one layer.
2. Double-layer sports wood floor: a composite structure mainly composed of surface floor, rough floor, keel layer, moisture-proof layer and elastic cushion blocks.
3. Multi-layer composite structure sports wood floor: In addition to the structural characteristics of double-layer sports wood floor, its keel layer is an advanced vertical cross-paved sports wood floor, which is an advanced sports wood floor at present.
Three, according to the classification of application materials
1. Surface material: solid wood flooring, solid wood integrated flooring and solid wood composite flooring are mainly used as surface materials. The surface floor is located on the upper floor of the sports wood floor structure, and its processing form is basically the same as that of the civil floor.
2. Wool floor: mainly made of soft pine (generally Pinus sylvestris var. mongolica). Mongolian oak, spruce, fir, etc. ) or multi-layer plywood (generally larch plywood, with a thickness of 12mm) and located between the surface floor and the keel layer.
3. Keel layer: mainly made of pine or multi-layer plywood or single-layer laminated timber (LVL).
