2. Description of the Related Art Conventionally, various deck materials made of synthetic resin have been developed and put on the market. FIG. 10 is a cross-sectional view showing an example thereof, in which a groove portion 101 is provided in the middle of a deck material 100 having a hollow structure, a stack piece 102 is provided at one end, and a receiving piece 103 and a drain groove 104 are provided at the other end. Formed,
The intermediate groove portion 101 is covered with a groove cover 105.

The deck material 100 has a receiving piece 10
While stacking the next stack material 102 of the deck material 100 on 3 and arranging it on the joist material 106 such as a veranda, the stopper 107
Is screwed into the joist 106 from the bottom of the groove 101 to fix each deck material 100, and the groove cover 105 is put on the groove 101 to perform the laying construction.

[0004]

However, since the main body portion of the deck material 100 excluding the groove cover 105 is integrally molded of synthetic resin, for example, the surface pattern or color may be partially changed, It was difficult to mold only the surface part with a synthetic resin having good weather resistance. Therefore, it is not easy to obtain a deck material whose surface has a variety of design changes, and in order to obtain a deck material with good weather resistance, the entire deck material must be molded with synthetic resin with good weather resistance. There was a problem that it had to be.

Moreover, in the above-mentioned deck material 100, since the watertightness of the groove cover 105 is not so good, rainwater that has entered the groove portion 101 leaks out from the insertion hole of the stopper 107, and corrodes and decays the joist material 106 and the like. In addition, there is a problem in that the end overlapping piece 102 has to be treated to prevent rainwater from leaking from the end.

The present invention is mainly intended to provide a deck material capable of solving these problems.

[0007]

In order to achieve the above-mentioned object, a deck material according to claim 1 of the present invention is a deck material main body made of synthetic resin and a plurality of surface material made of synthetic resin. The deck material main body has a groove portion through which a stopper is inserted in the bottom surface, a pair of narrow-width ridges located on both sides of the groove portion, and the same height as the narrow-width ridge. Other wide ridges are provided, and the width of the wide ridges is the same as the total width of the pair of narrow ridges and the groove portion therebetween, and the surface material is a flat plate portion, The pair of leg plate portions are provided with a pair of leg plate portions projecting from the back surface of the flat plate portion, and the mutual distance between the pair of leg plate portions is substantially the same as the width of the wide ridge of the deck material main body. Are fitted to the outside of the pair of narrow ridges or the outside of the wide ridges of the deck material so that each surface material One piece is attached to each of the wide ridges and the wide ridges, and the flat plate portion of each surface material is supported by the pair of narrow ridges or wide ridges, and is located along one side edge of the deck material main body. The surface material adhered to the wide ridge or the pair of narrow ridges is characterized by having a drain side groove having a U-shaped cross section at one side end of the flat plate portion.

The deck material according to claim 2 is the deck material according to claim 1, wherein engaged portions are formed on an outer surface of the wide convex ridge and an outer surface of the pair of narrow convex ridges of the deck material main body. At the same time, the engaging portion is formed on the inner surface of the leg plate portion of the surface material,
The surface material is attached to the wide-width ridge and the pair of narrow-width ridges one by one in a state where the engaging portion engages with the engaged portion from below.

In the deck material according to the first aspect of the present invention, since the deck material main body and the surface material are separate bodies, various kinds of surface materials having different patterns and colors are prepared in advance, and the desired pattern is selected from them.
