When the white pigment particles supported on the surface of the cellulose-based fine particles are made of titanium oxide, the titanium oxide is thermally and chemically stable and has excellent coloring power and hiding power. As a result, the color tone of the molded product 1 constituted by the molded member 10 can be reliably adjusted, and the color tone of the molded product 1 is less likely to change over time.

Further, since the molded member 10 contains 30 to 65% by weight of cellulosic fine particles, since the molded member 10 contains a large amount of cellulosic fine particles, the texture of the molded article 1 is closer to that of natural wood. And texture can be imparted. Here, when polypropylene is mainly used as the resin when forming the molded member, the quality of the molded member 10 such as the homogeneity of the material can be stably maintained even if the cellulose-based fine particles are added up to about 65 wt%.

Are arranged such that the opening 13a of the above-mentioned distal end portion 11 of the cut piece 10B, that is, the opening 13a of the frame-shaped molded article 31, is arranged below. The base portion 42 in the longitudinal direction is set on the large quoted floor bundle 70 such that the base end portion 42 is in contact with or close to the wall 111 of the building 110. In this state, the openings 13a of the plate-like molded product 1 constituting the floor structure 100 are all vertically downward. The installation is performed by the following method. That is, as shown in FIG. 10, mounting members 50,... (Only two are shown in FIG. 5) are attached to the lower surface of the plate-shaped molded product 1 in advance. The plate-like molded product 1 is set on the large pulley 60 by being inserted and fixed in the locking holes 61 provided in the upper angle member.

As described above, according to the first embodiment, the cutting surface of the cut piece 10B and the cut surface of the molded member main body 10A intersect with the tip 11 of the cut piece 10B in the longitudinal direction of the molded member main body 10A. Therefore, the plate-like molded product 1 in which the longitudinal direction of the molded member body 10A, that is, the longitudinal direction of the molded member 10 is not opened, can be manufactured. Further, since the cut piece 10B, which is a part of the molding member 10, is used as a covering member for covering the opening 13a of the distal end portion 11 of the molding member 10, the covering member according to the size and shape of the opening of the molding member 10 is used. It is not necessary to separately prepare a cover member, and the cover member can be easily obtained. Further, in the manufactured plate-shaped molded product 1, since the tip 11 of the cut piece 10B is opened in a direction intersecting with the longitudinal direction of the molded member main body 10A, a plurality of plate-shaped molded products 1 can be formed. When constructing a floor 101 such as a terrace which is installed horizontally, a plurality of plate-like molded products are arranged such that the opening 13a of the tip end portion 11 of the cut piece 10B, that is, the opening of the plate-like molded product 1 is arranged below. By installing 1, ..., the opening of the plate-shaped molded product 1 can be directed downward of the floor 101 without facing the end face side of the floor 101. Furthermore, water that has entered the inside of the plurality of plate-shaped molded products 1 can be drained downward from the openings of the plate-shaped molded products 1.

Further, since the longitudinal direction of the molded member 10 and the oblique direction form an angle of 45 degrees, the end of the molded member 10A constituting the plate-like molded product 1 is perpendicular to these longitudinal directions. Can be closed.

Further, since the plate-shaped molded article 1 is manufactured using the molded member 10 formed by mixing the above-mentioned cellulose-based fine particles and a resin, and melting and molding the mixed material, the plate-shaped molded article 1 is manufactured. The molded article 1 can be imparted with waterproofness, antiseptic properties and woody feel.

Further, a plate-like molded product 1 is manufactured by using a molded member 10 formed by adding a pigment to the cellulose-based fine particles and the resin and mixing the resulting mixture, and melting and molding the mixed material. Therefore, it is possible to impart waterproofness and antiseptic property to the plate-shaped molded product 1 and to impart various colors to the plate-shaped molded product 1, thereby enhancing the woody feeling of the plate-shaped molded product 1. Can be.

[0110] Further, since the particle diameter of the cellulose-based fine particles is 1 to 300 µm, the moldability when molding the molded member 10 by a method such as extrusion molding is improved, and the cellulose-based fine particles are formed into a frame-like form. It can be uniformly dispersed throughout the article 1. In addition, since the particles of the wood flour appearing on the surface of the molded member 10 are fine, the surface becomes smooth and the surface treatment of the molded member after molding can be easily performed.

Further, since the white pigment particles are carried on the surface of the cellulose-based fine particles, the cellulose-based fine particles having the white pigment particles carried on the surface come closer to the surface of the molding member 10 than the colored pigment. In this case, the color of the colored pigment beneath it is concealed, whereby the color of the surface of the molded member 10 formed by the colored pigment becomes uneven, and the surface of the plate-shaped molded article 1 Can be approximated. Further, when the surface of the molded member is ground, the white pigment particles carried on the surface of the cellulosic fine particles are scraped off and the cellulosic fine particles are exposed, so that the plate-shaped molded article 1 is made more woody. It can be.

When the white pigment particles supported on the surface of the cellulose-based fine particles are made of titanium oxide, the titanium oxide is thermally and chemically stable and has excellent coloring power and hiding power. As a result, the color tone of the plate-like molded product 1 constituted by the molding member 10 can be reliably adjusted, and the color tone of the plate-like molded product 1 is less likely to change over time.

Since the molded member 10 contains 30 to 65% by weight of cellulosic fine particles, since the molded member 10 contains a large amount of cellulosic fine particles, the plate-shaped molded article 1 is made of natural wood. A close touch and texture can be provided. Here, when polypropylene is mainly used as the resin when forming the molded member, the quality of the molded member 10 such as the homogeneity of the material can be stably maintained even if the cellulose-based fine particles are added up to about 65 wt%. Can be secured.

Further, since resin is contained in the molded member 10 in an amount of 20 to 45 wt%, the strength and hardness of the plate-shaped molded product 1 constituted by the molded member 10 can be sufficiently obtained, and the molding can be performed. The moldability when molding the member 10 by a method such as extrusion molding is improved.

[0115] Since at least a part of the cellulose-based fine particles is obtained by pulverizing wood waste material, it is possible to effectively use the wood waste material generated by dismantling a building or the like.

In addition, since at least a part of the resin is obtained by pulverizing resin waste containing impurities, the resin waste can be effectively used. In particular, since the same type of resin waste is often collected together, it is easy to determine the properties of the resin waste, etc., and select and use the type of resin waste suitable for forming molded parts. can do. Further, when the pigment is contained in the resin waste material, the pigment can be reused, and the amount of the pigment used at the time of forming the molded member can be reduced.

Further, since the total amount of impurities contained in the molded member 10 is 20 wt% or less, the moldability of the molded member 10 when molded by a method such as extrusion molding is improved, and the molded member 10 has Since impurities are contained, the plate-shaped molded article 1 excellent in terms of effective use of resources and environmental protection can be manufactured.

Further, since the surface of the plate-shaped molded article 1 is subjected to the sanding treatment, the amount of the cellulosic fine particles exposed on the surface of the plate-shaped molded article 1 can be increased. The surface texture can be made closer to that of natural wood.

A plurality of grooves 21 having the same width and different depths, a plurality of grooves 22 having the same depth and different widths, or the depth and width are formed on the surfaces 15 to 18 of the molded member 10. Is formed of a plurality of grooves 23, each of which has a different shape, so that the surface of the molded member 10 becomes three-dimensional, and the appearance and feel of the plate-shaped molded product 1 can be made closer to that of natural wood. it can. In particular, when the grooves 22 formed on the surface of the molded member 10 have the same depth, a wood grain pattern is formed on the surface of the molded member 10 having the hollow portion 13 and the outer peripheral surface formed to have a constant thickness. It is suitable for

Further, since the groove 21 (or 22, 23) is formed by sanding, the groove 21 (or 22, 23) is simultaneously formed while the surface of the plate-shaped molded article 1 is subjected to sanding. Can be formed.
