Sports wood floors with different uses and structural forms directly affect their cost and performance indicators. Therefore, the structural forms of sports wood floors are mainly divided into single-layer, double-layer and multi-layer composite structures.
(1) Single-layer structure sports wood floor: also known as economical structure sports wood floor. It is mainly composed of surface floor and keel layer (abbreviation: single-layer keel sports wood floor) or only one layer of floor is laid on the floor of indoor gymnasium.
(2) Double-layer structure sports wood floor: a composite structure mainly composed of surface floor, raw floor layer, keel layer, moisture-proof layer and elastic cushion layer.
(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 excellent sports wood floor with equal spacing and vertical cross-paving, which is currently an excellent sports wood floor. 3 3. Press Applied Materials Classification
(1) Surface material: mainly use solid wood floor, solid wood integrated floor or solid wood composite floor as the surface floor material. The surface floor is located on the uppermost layer of the sports wood floor structure. The processing form of the surface floor is basically the same as that of the civil floor. same.
(2) Fur floor: mainly soft pine boards (usually pine, spruce, fir, etc.) or multi-layer plywood (usually larch plywood with a thickness of 12mm), and the fur floor is located on the surface layer Between the floor and the keel layer.
(3) Keel layer: solid wood or man-made boards mainly use pine square timber or multi-layer plywood or laminated veneer lumber (LVL) as the keel material.
