The main body of the present invention adopts recombined bamboo, which is green and environmentally friendly, and is connected together by a soft light-curable resin layer 1 and a load-bearing yarn 3. The whole is a foldable and curlable flexible structure. The light-curable resin layer 1 may specifically contain an ultraviolet photosensitizer Polyurethane acrylate and other photocurable resins are composed of resin monomers (monomer) and prepolymers (oligomer), which contain active functional groups, and can be polymerized by a photosensitizer (light initiator) under ultraviolet light irradiation. Physical and chemical changes occur rapidly within a short period of time, thereby cross-linking the cured oligomer. Photocurable resin is a photosensitive resin with a relatively low molecular weight, which has reactive groups that can be photocured, such as unsaturated double bonds or epoxy groups. The present invention can usually be wound into a roll during transportation and storage, which takes up less space and is not easily broken. Upwards, the supporting part 22 is downwards, which is very convenient. After paving, ultraviolet light is used to irradiate the upper surface of the present invention, so that the photocurable resin layer 1 is cured rapidly, so that each recombined bamboo slat 2 is firmly fixed, and the floor becomes One-piece structure, strong integrity, smooth and firm. As the ribs of the light-cured resin layer 1, the load-bearing yarn 3 has a certain strength, so that the light-cured resin layer 1 can effectively connect the recombined bamboo slats 2 in an uncured state, and after the light-cured resin layer 1 is cured, the load-carrying yarn 3 The yarn 3 can also be used as ribs, so that the overall structure of the floor is firm and durable. When the photocurable resin layer 1 is not cured, the position limiting card part 31 can limit the position of the recombined bamboo slat 2, prevent the reorganized bamboo slat 2 from moving on the load-bearing yarn 3, and ensure that the photocurable resin layer 1 is cured. The reorganized bamboo slats 2 are in a neat working state parallel to each other and equidistant. Moreover, the filling portion 12 of the photocurable resin layer 1 can integrally connect and support the adjacent main body portion 11, further enhancing the strength of the present invention after curing. As the uppermost end of the floor, the penetration part 212 presents the property of recombined bamboo, which is wear-resistant and beautiful.

Preferably, the load-bearing yarn 3 includes a yarn core body 32 and a helical burr layer 33 spirally wound outside the yarn core body 32 in a helical shape. There is a gap for accommodating the photocurable resin material between them, the diameter of the through hole 211 is larger than the diameter of the yarn core 32, when the flexible photocurable resin is coated on the bearing yarn 3, the burrs 331 of the helical burr layer 33 will contact with the yarn core 32. The photocurable resins are embedded and firmly interlocked together, and the photocurable resin can be reinforced no matter before or after the photocurable resin layer 1 is cured, so that the photocurable resin is not easy to fall off; and after the spiral burr layer 33 passes through the through hole 211, the burr 331 The yarn core body 32 can be supported from various directions, so that the yarn core body 32 is at the axis of the through hole 211, so that the photocurable resin layer 1 can penetrate into the In the through holes 211, the photocurable resin of the photocurable resin layer 1 can pass through each through hole 211, so that the photocurable resin connects all the main parts 11 and filling parts 12 to form a whole piece of photocurable resin layer 1, and the strength is further improved. .
