Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.
In FIG. 1, the vegetable garden structure 1 which has the joining structure of the member which concerns on this invention is shown.
The vegetable garden structure 1 is constructed mainly using a member made of an extruded material, and has a bottom board part 11 having a hollow part extending with a substantially rectangular plate-like flat part, and vertically upward from four corners of the bottom board part 11. It has the pillars 12 and 12 extended and attached.
Further, the cross beams 13 and 13 are passed between the upper ends of the columns 12 and 12, and both end portions of the cross beams 13 and 13 are joined to the upper end of the column 12 via the joint structure portion 2.

Further, a plurality of vertical beams 14, 14... Are passed at regular intervals in a direction crossing the horizontal beams 13, 13 in a manner of passing between the upper surfaces of the horizontal beams 13, 13. The vertical beams 14, 14. The ends of the horizontal beams 13 and 13 extend further laterally from the upper surfaces of the horizontal beams 13 and protrude outward from the substantially rectangular region formed in the space vertically above the bottom plate 11. Further, in the plurality of vertical beams 14, 14,..., Vertical beams 14a, 14b that extend further than the other vertical beams 14, 14.
On the other hand, a pair of pillars 15 and 15 are erected directly on the ground so as to extend vertically upward from the ground outside the bottom base part 11, and the upper ends of the pillars 15 and 15 and the vertical beams 14a and 14b The tip portion is joined via the joint structure portion 2.

  The plate-like bottom plate part 11 is an adhesive between the waste resin pulverized material obtained by pulverizing the waste material resin, the wooden waste material pulverized powder obtained by pulverizing the wood waste material, and the wood waste material powder and the waste resin pulverized material. It is formed from an extruded material obtained by mixing maleic anhydride as an auxiliary agent and a pigment into a mixed material, melting the mixed material, and extrusion molding.

The waste material resin is obtained by pulverizing a polypropylene packaging member such as a tray and a food container collected after being used for packaging of food or the like, and a polypropylene scrap material produced when the polypropylene packaging member is formed.
Wood waste materials include wood waste materials that are discharged when a building such as a house is dismantled, wood waste materials that are discharged when a furniture is dismantled, wood scraps that are discharged during building construction, sawdust, and the like.

  The exterior material 161 is formed by mixing and melting cellulose-based fine particles and a resin. Cellulose-based fine particles can be obtained, for example, by crushing wood waste materials discharged when a building such as a house is demolished, scrap materials discharged during building construction, and wood waste materials such as sawdust with a known crusher. Examples thereof include wood flour and wood flour obtained by pulverizing natural wood such as wood, bacas, and rice straw.

  Examples of the resin include a resin obtained by pulverizing a tray and a packaging member such as a food container collected after being used for packaging of food with a known pulverizer, a resin obtained from natural wood, and the like. . That is, vinyl chloride resin, foamed vinyl chloride resin, polyethylene resin, phenol resin, urethane resin, polyurethane resin, ABS resin, polystyrene resin, and the like. The exterior material 161 is manufactured by uniformly mixing the cellulose fine particles and the resin to obtain a mixed material, and then heating and melting the mixed material with an extruder to perform extrusion molding. The surface of the exterior material 161 obtained in this way is finished by, for example, applying a grain pattern (not shown) or painting with sanding paper or the like.
