It may be rough, and may further comprise the step of drying the wood powder after stirring to dry. In addition, the second surface-modified wood flour may be prepared by plasma treatment of wood flour from the viewpoint of improving the binding force between the base layer and the surface layer and improving the mechanical strength of the surface layer. Through such a plasma treatment, there is an advantage that high mechanical strength can be achieved by uniformly mixing the second olefin resin with no separation in the surface layer.

That is, the double-extruded synthetic wood is the main extrusion layer by adding a first surface-modified wood powder surface-treated with a siloxane compound to the main extrusion layer, and a second surface-modified wood powder surface-treated with plasma to the auxiliary extrusion layer, And to make each of the auxiliary extrusion layer is uniformly mixed, the binding force of the main extrusion layer and the auxiliary extrusion layer may be improved.

The top surface 110 of the deck 100 may have a top groove (110a), the top groove (110a) can induce the flow of water when the snow melts or rain to flow the water to the outside on the deck rod By doing so, you can reduce the amount of time that water stays on the deck. Therefore, it is possible to improve the durability of the deck rod against moisture, and to help the safety of walking by minimizing slippery when walking.

The lower surface 190 of the deck 100 may include a lower surface groove 190a to reduce frictional force with the support frame 400 to be coupled thereafter.

As shown in FIG. 7, the deck 100 has a pair of decks positioned on both sides of the deck coupler 200 to be symmetrical, and is located between the coupling groove 150 and the deck located at each end surface 130 of the deck. Combination of the deck coupling sphere 200 can form a linear deck rod module. Therefore, the trench 170 located at one side of the upper surface of the deck 100 may form a connection groove in a direction perpendicular to the coupling of the deck rod module by a combination of linear deck rod modules.

That is, for example, when the deck rod module in the form of a row by combining the deck 100 using the deck rod coupler 200, deck rod connecting bar 300 for the connection of each row (deck rod module) ) Is coupled to the trench 170 to form a column, the deck rod can be completed. On the contrary, when the deck rod module is configured in the form of a row by combining the deck 100 using the deck rod coupler 200, the deck rod connecting bar 300 for the connection of each row is coupled with the trench 170. The deck load can be completed by forming a row. Therefore, by installing the deck rods by connecting the decks in rows and columns without additional through holes in the deck rod module, it is possible to prevent stiffness and crack problems caused by the through holes, and to maintain the fixing force to improve the durability of the deck rods. .

Space may be formed. Therefore, water or moisture due to the rain can be induced to flow to the outside between the deck 100 and the deck rod coupler 200, and helps to dry the deck rod after the rain has stopped by providing a space for air flow Can give

The deck rod coupler 200 may include a protrusion 250 formed on an upper surface along a center line of the block insertion unit 210. Therefore, even if a force acts downward of the block inserting portion 210 toward the center line of the plate-shaped block inserting portion 210 by pressing the ends of both decks (F), the block inserting portion 210 due to the protrusion 250. By reinforcing the center line, it is possible to prevent the bending of the block insertion portion 210 against external force and may further help durability.

Furthermore, the block contact portion 220 may include a first contact portion corresponding to one end surface 130 of the deck 100 and a second contact portion symmetrically formed at both ends of the first contact portion, and an edge of the second contact portion. Is processed in a curved shape to protect the contractor during deck rod installation work, and can help the pedestrian safety even if exposed after installation.

In addition, the block inserter 210 may have a groove in an area corresponding to a boundary where the first contact portion and the second contact portion meet. Therefore, it may be easy to discharge the moisture such as rain water flowing down the upper surface of the block inserting portion 210 to the groove to the outside. Furthermore, by providing grooves at corners where moisture and moisture tend to accumulate, imparting breathability and preventing moisture from accumulating on the edges of deck 100 even in usual times, the durability of deck 100 may be further improved. In addition, the thickness of the first contact portion is formed to be thinner than the thickness of the second contact portion, it is possible to facilitate the discharge to the outside when the amount of rain water or water flowing from the outside between the deck block 100 increases. Furthermore, the space between the support frame 400 positioned between the support binding portion 230 by providing a length difference between the first contact portion and the second contact portion so that the water discharge and the air flow can be easily performed. ) Durability can be further improved.

The support binding unit 230 may be connected in a plate shape orthogonal to the lower ends of both sides of the block contact portion 220 and spaced apart in parallel to each other, and may include locking protrusions 232 formed inwardly at one end thereof. Therefore, the support frame 400 is inserted into a space formed between the support binding unit 230, but the support frame 400 may be fixed by the locking protrusion 232.

Furthermore, the deck rod coupler 200 may include a reinforcement part 240 extending from both ends of the block contact portion 220 and vertically connected to an outer surface of the support binding portion 230. Since the end portion of the block contact portion 220 and the support binding portion 230 are connected to each other in a form orthogonal to each other, the reinforcement portion 240 may be further provided to increase durability of the connection region.
