There is no main tenon on both sides of the main body of the floor, and there are connecting grooves, micro-seam positioning tenons and micro-seam control tenons respectively. Their functions are: to cooperate with the supporting connection card to install the floor; The micro-seam positioning tenon allows the floor to stretch freely, and the micro-seam is narrowed to prevent the floor from arching. The support connection card is composed of six parts: the support connection card base 3; the barb connection tenon 3.1 on the left side of the upper end of the support connection card, and the barb connection tenon 3.2 on the right side of the upper end of the support connection card; the fixed-thickness support column 3.3 in the middle; the support connection The spare screw hole 3.4 on the left side of the card base 3 supports the screw hole 3.5 on the right side of the card base 3. The advantages of the present invention are: single-layer structure, no main tenon, saving a lot of forest resources, only the traditional sports floor consumes forest Less than one-twentieth of resources.
