Description

  The present invention relates to benches and tables, yatsuhashi bridges, board walks installed on boardwalks, park facilities, etc., as well as stadium seats, or veranda or terrace decks.

  Originally, natural wood was used for the various deck floors described above, but natural wood is limited in resources and very expensive. Moreover, since many decks are installed outdoors, there is a drawback that natural wood is easily decayed.

  Therefore, deck materials (resin molded products) molded using wood materials have come to be used as deck materials. This deck material is a deck material formed from a mixed material of wood powder or wood fiber and resin, and is not easily decayed, and is far superior to natural wood in weather resistance performance. In addition, a solid material was initially used. However, a solid material is used, and a hollow material is used because of the high cost. Due to advances in materials, structures, and molding methods, performance such as strength is improved, and this hollow deck material is generally used.

On the other hand, when a hollow deck material is used, a hollow cross section appears at the end (end face), which causes a problem of poor appearance. In order to solve this problem, a curtain is attached as a decorative material to an end portion where a hollow cross section appears, and the cross section is covered (Patent Documents 1 and 2).

  However, according to the method of attaching the decorative material to the end of the deck floor using the hollow deck material as in the deck floor described in the above patent document, the decorative material itself needs to be prepared and attached as a separate member. In addition to this, it is necessary to devise the structure of the metal fittings and the mounting surface for the mounting, and the mounting work. Therefore, the number of components on the deck floor is increased, and the installation work of the deck is complicated, and there is a problem that extra time is required.

  On the other hand, solid artificial deck materials that can be handled in the same way as natural wood and have a beautiful end face are still highly evaluated. However, as described above, there is a problem that the cost is high.

  The present invention has been made to overcome the above-described problems, and can maintain the aesthetics of the end face without attaching a decorative material to the end of the deck floor. The purpose is to provide a deck floor with reduced installation costs.

In order to achieve the above object, the deck floor according to the present invention is a deck floor formed by connecting a plurality of long deck materials vertically and horizontally, and the deck material is hollow and has a predetermined width and thickness. A hollow deck material extending in an equal cross-sectional shape along the longitudinal direction, and a solid deck material having a solid inside and extending in an equal cross-sectional shape along the longitudinal direction with the same width and thickness as the hollow deck material. provided, of the decking, and a solid decking end member longitudinal end surface thereof is exposed, there any other intermediate material as a hollow decking, and said deck member are both wood flour or It is a synthetic resin molding containing a wood fiber.

  According to the deck floor according to the present invention, since the end member where the end surface is visible is made solid, the aesthetic appearance is not impaired, while the hollow artificial deck material is used for the intermediate material where the end surface is not visible. Therefore, the amount of material used is small, and the cost of the entire deck floor can be kept low.

  In addition, since there is no need to attach decorative material to the edge of the deck floor, the number of parts for constructing the deck floor, such as decorative material and its mounting hardware, can be reduced, and complex decorative material installation work is required. This makes it easier to install the deck floor.

  It is preferable that the end member and the intermediate material have the same or similar strength such as flexural modulus, water absorption and other physical properties. If it does in this way, when walking on the said deck floor after installation of a deck floor, even if it steps on the connection part of an end member and an intermediate material, there is no sense of incongruity.

  Further, it is preferable that the surface layer portion of the end member and the surface layer portion of the intermediate member have the same or similar texture and pattern having a wood texture. By doing so, the solid end member and the hollow intermediate member cannot be distinguished from each other in appearance, and the appearance is excellent.

  Further, each of the end member and the intermediate material is composed of a core material portion and a surface layer portion, and the material of the surface layer portion of the end member and the material of the surface layer portion of the intermediate material are shared by the same material. It is preferable to make it.

  In this way, there is no distinction between the solid end member and the hollow intermediate material in appearance, the aesthetics are further improved, and the material used for the surface layer portion of both members is easy to prepare. It becomes. Further, in this case, it is possible to further reduce costs by using recycled resin for the core part of the solid deck material.

  According to the deck floor according to the present invention, since the solid deck material is used as the end member, the aesthetic appearance of the end surface can be maintained without attaching a decorative material to the end portion of the deck floor. Further, since a hollow deck material is used as the intermediate material, the amount of material used can be reduced, and the cost of the entire deck floor can be reduced.

  Furthermore, since it is not necessary to attach a decorative material to the end portion and a decorative material mounting bracket for that purpose is not required, not only a complicated decorative material mounting operation is required, but also the number of parts constituting the deck can be reduced. Therefore, the work for installing the deck floor is easy and the cost can be further reduced.

  BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment of a deck floor according to the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a perspective view showing an installed state of a deck floor according to the present invention. FIG. 2 is a perspective view showing a state during the installation of the deck floor according to the present invention. 3 is a sectional view taken along line AA in FIG. 1, FIG. 4 is a sectional view taken along line BB in FIG. 1, and FIG. 5 is a sectional view taken along line CC in FIG. It is.

  As shown in FIG. 1, the deck floor 1 in this embodiment is formed by arranging a plurality of deck materials 2 and 3 on a metal joist 5. The joist 5 is supported by a support member 6 from below, whereby the deck floor 1 and the joist 5 are installed at a distance from the ground surface. As shown in FIG. 2, the deck members 2 and 3 are sequentially disposed on the joist member 5 and fixed with screws 4.

  Further, the deck floor 1 in this embodiment is configured by arranging a plurality of deck materials 2 and 3 vertically and horizontally. Of the deck materials constituting the deck floor 1, solid end deck materials are used for the end members 2 where the end surfaces in the longitudinal direction are exposed, and hollow portions 33 are used for the intermediate materials 3 where the end surfaces are not exposed. The deck material you have is used.

  As a result, as shown in FIGS. 3 to 5, the AA cross section is composed of only the solid end member 2, and the BB cross section includes the solid end member 2 and the hollow intermediate member 3. Are lined up alternately. Moreover, between CC, it is comprised only with the hollow intermediate material 3. FIG.

  By configuring in this way, only the end surface 2a of the solid end member 2 is exposed on the end surface of the deck floor 1 and the woody texture appears, so that it is aesthetically pleasing, There is no need to attach cosmetics. And since the hollow deck material is used for the intermediate material 3, the usage-amount of material is also small and the material cost of the deck floor 1 is suppressed.

  Each of these deck materials 2 and 3 is formed from a synthetic resin material containing wood powder or wood fiber (hereinafter referred to as “wood powder or the like”). As the wood flour, those of coniferous species such as cedar and batesga are generally used, but the type is not particularly limited as long as it is a pulverized product of plant fibers. In addition to the above-mentioned wood powder, additives such as coloring pigments that cause wood texture to appear in combination with wood powder, fillers such as calcium carbonate and stone powder, foaming agents, foaming aids, ultraviolet absorbers, antistatic agents, etc. Etc. may be appropriately blended as necessary.

  As the synthetic resin material, any synthetic resin can be used as long as it can be molded by extrusion molding, injection molding or the like. For example, thermoplastic synthetic resins such as polyvinyl chloride, ABS resin, polyamide, acrylic resin, and other thermosetting synthetic resins such as phenol resin, polyester, and urea resin can be used. The main component is a polyolefin resin such as polyethylene, polypropylene, polybutene, polyisoprene, ethylene vinyl acetate copolymer, ethylene ethyl acrylate copolymer, ethylene α-olefin copolymer, and olefin elastomer.

  The deck materials 2 and 3 are made by adding the above-mentioned wood powder to these synthetic resins, and further blended with color pigments, fillers, additives, etc., and made into powder or pellets, extrusion molding, injection molding, etc. Is formed into a desired shape such as a plate shape.

  These deck materials 2 and 3 have a two-layer structure of core portions 21 and 31 and surface layer portions 22 and 32, and both the core material portion and the surface layer portion are made of synthetic resin containing wood powder or wood fiber. It is made of a material. In order to adhere and integrate the surface layer portions 22 and 32 around the core material portions 21 and 31, it is preferable to integrally form them at the time of molding such as extrusion molding or injection molding. .

  Moreover, in this embodiment, the material of the surface layer part 22 of the end member 2 and the material of the surface layer part 32 of the intermediate member 3 use a common material. By adopting such a configuration, in the state in which the deck floor 1 is installed, the difference between the end member 2 and the intermediate member 3 is not recognized at all in appearance.

  The end members 2 and the core members 21 and 31 of the intermediate member 3 are both made of a synthetic resin material containing wood powder or wood fiber, but generally the content of wood powder or wood fiber is increased. It is known that the strength of the deck material is increased.

  Therefore, for the core material 21 of the solid end member 2 in this embodiment, the content ratio of wood powder or wood fiber is blended by 50 parts by weight or more (up to 150 parts by weight) with respect to 100 parts by weight of the synthetic resin. preferable. In addition, while increasing the content of wood powder or wood fiber, so-called recycled resin (recycled resin) is used as a synthetic resin to reduce material costs.

  On the other hand, for the core material 31 of the hollow intermediate material 3, the content ratio of wood powder or wood fiber is 50 parts by weight or more (up to 150 parts by weight) with respect to 100 parts by weight of the synthetic resin, and as the synthetic resin, In order to maintain strength, so-called virgin resin is used. In general, virgin resin is more expensive than recycled resin. However, since the intermediate material 3 is hollow, the amount of material used is small, and the cost can be greatly reduced compared to a solid resin.

  The thickness of the core parts 21 and 31 is not particularly limited, and may be thin. However, the thickness of the core parts 21 and 31 can be increased by increasing the amount of compounding ingredients such as wood flour and the like, and about 20 mm. The above thick wall is preferred. On the other hand, the thickness of the surface layer portions 22 and 32 can make the texture and pattern with a wood texture more clearly appear in the appearance when the thickness is thinner than the thick thickness, and also contains additives such as UV absorbers. In order to improve the weather resistance, the thinner one is economical because the amount of the additive is small, and generally about 0.5 to 5 mm is preferable.

  Furthermore, as described above, in the synthetic resin material used for the core members 21 and 31 of the end member 2 and the intermediate member 3, by adjusting the content of wood powder or wood fiber and the type of resin used, the end member If the strength and other physical properties of the intermediate member 3 and the intermediate member 3 are approximated, even if a person steps on the connecting portion between the end member 2 and the intermediate member 3, a sense of incongruity is not felt.
