[0001]
[Industrial applications]
The present invention relates to a floor board and a floor structure for a wooden floor that frequently gets wet with water, such as outdoors.
[0002]
[Prior art]
As described in Japanese Patent Application Laid-Open No. H11-280237, an outdoor floor in which a plurality of floorboards are arranged side by side on a waterproofed floor substrate, and drainage grooves are continuously formed on the sides of the floorboards. In the structure of (1), an outdoor floor has been proposed in which a concave groove parallel to the joint is formed below the joint between the floor plates, and one end of each concave groove is connected to the drainage groove.
According to this outdoor floor structure, it is not necessary to form the lower surface of the floor plate in a complicated shape, the production cost of the floor plate can be suppressed as much as possible, and a concave groove is formed below the joint between the floor plates. Since the water that enters between the floorboards is received and drained by the concave grooves, the waterproof performance can be improved.
[0004]
[Problems to be solved by the invention]
However, it is necessary to provide a waterproof ground floor under each floorboard, and to form a drainage groove continuously on the side of each floorboard, and to form a joint between the floorboards below the joint. It is necessary to form parallel concave grooves, and one end of each concave groove must be continuous with the above-mentioned drain groove, which makes the structure complicated and expensive.
[0005] An outdoor wooden floor is referred to as a deck flooring, but it is often desired to adopt it because it looks warm. However, in the case of outdoors, it is necessary to pay special attention to drainage because it gets wet with rain. However, as described above, providing a complicated drainage structure in addition to the floor plate increases the cost.
If the floorboards are tightly fitted without employing the above-mentioned drainage structure, drainage will be poor and the floor will be warped because it absorbs and swells. Therefore, a hard plate that is hard to swell by absorbing water is used.
However, even if a hard plate is used, it is difficult to reliably prevent warpage. The problem is that, if a gap is provided between adjacent plates, drainage is improved and drainage is improved, so that warpage can be suppressed. However, providing a gap penetrating below the floor between adjacent floorboards results in a decrease in construction quality and must be avoided.
A technical object of the present invention is to realize a floor structure and a floor plate having good drainage without paying attention to such a problem without deteriorating construction quality.
[0009]
[Means for Solving the Problems]
The technical problem of the present invention is solved by the following means. Claim 1 forms one side edge of the longitudinal direction of a floor board in the shape of a concave groove, and forms the other side end in a convex strip of a size that can fit in the concave groove of the adjacent floor board, A floor plate material characterized in that the protrusion amount of the ridge is larger than the depth of the concave groove.
[0010] As described above, one side end in the longitudinal direction of the floorboard is formed in a concave shape, and the other side end is formed in a convex shape having a size capable of being fitted into the above-described groove in the adjacent floorboard. At the same time, since the amount of protrusion of the ridge is larger than the depth of the groove, when laying this floor plate, the protrusion on the side end is fitted into the groove of the adjacent floor plate to form a protrusion. The part on the base side of the strip that cannot be fitted into the concave groove is the drain groove.
Therefore, the drainage can be effectively drained by collecting the drainage in the drainage groove without opening a gap penetrating to the back surface between the adjacent floor plate members. As a result, it is possible to effectively prevent the floorboard from absorbing water and swelling or warping.
According to a second aspect of the present invention, there is provided a floor plate material characterized in that a drainage through hole is formed at a root side of the ridge according to the first aspect which cannot be fitted into a concave groove of an adjacent floor plate material. .
[0013] As described above, since the drainage through-hole is formed at the base side of the ridge that cannot be fitted into the concave groove of the adjacent floor plate, the floor ridge is laid when the floor plate is laid. The water that has flowed into the drainage groove formed on the root side can be effectively drained to the lower surface side through the through-hole and drained.
According to a third aspect of the present invention, there is provided a floor plate material according to the first or second aspect, wherein one surface of the floor plate material is formed flat, and the other surface is formed in an uneven shape.
As described above, since one surface of the floorboard is formed flat and the other surface is formed in an uneven shape, when laying the floorboard, it is possible to lay the floorboard in accordance with the place of installation or by the owner. If desired, the flat surface or the uneven surface may be laid with either side facing upward.
According to a fourth aspect of the present invention, a ridge formed on the other side end of an adjacent floor plate is fitted into a concave groove formed on one side end in the longitudinal direction of the floor plate, and a root side of the ridge is formed. Is a floor structure which is not fitted into the concave groove but is left as a drain groove. If the amount of protrusion of the ridge is larger than the depth of the groove, a drainage groove is formed in an excess portion that cannot be fitted into the groove, but the amount of protrusion of the ridge is approximately the same as the depth of the groove or the groove. If the depth is smaller than the depth, the drainage ditch can be easily formed to a constant width by fixing each floor plate to the joist with the spacer member inserted between adjacent floor plates at the base of the ridge. it can.
As described above, the ridge formed at the other side end of the adjacent floor plate is fitted into the concave groove formed at one side end in the longitudinal direction of the floor plate, and the root at the base side of the ridge is formed. Since the portion has a floor structure left as a drainage groove without being fitted into the concave groove, water on the floor plate surface flows into the drainage groove, which facilitates drainage. As a result, it is possible to effectively prevent the floorboard from absorbing water and swelling or warping.
According to a fifth aspect of the present invention, the projecting amount of the convex ridge is made larger than the depth of the concave groove according to the fourth aspect. The floor structure is characterized in that the root side portion is left as a drainage groove without being fitted into the concave groove.
As described above, by making the amount of protrusion of the ridge larger than the depth of the groove, even if the ridge is inserted into the depth of the groove, the root-side portion of the ridge is formed as described above. Since it is not fitted into the groove but is left as a drainage groove, even if the structure is such that a convex ridge is fitted to the depth of the groove to improve the connectivity between adjacent floor plates, water on the floor surface can be improved. Flows into the drain and is effectively drained.
A sixth aspect of the present invention is characterized in that a drainage through hole is formed at a root side of the ridge according to the fifth aspect which cannot be fitted into a concave groove of an adjacent floor plate. It is the floor structure described.
As described above, since the drainage through-hole is formed at the base of the ridge which cannot be fitted into the groove of the adjacent floor plate, the ridge flows into the drain formed on the ridge. Since water easily flows downward from the through hole, drainage becomes more reliable.

BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment will now be described of how the floorboard and floor structure according to the invention are embodied in practice. FIG. 1 is a perspective view showing only one floorboard according to the present invention. The upper surface 1 of the floor board P is uneven. That is, in the case of the illustrated example, the cross-sectional shape is formed in a waveform by continuously forming countless convex ridges. On the other hand, the back surface, that is, the lower surface 2 is formed flat. In use, either side may be up.
The floor plate P has a concave groove 3 by forming one side end in the longitudinal direction thereof into a concave groove shape. On the other hand, a ridge 4 is formed on the other side end. As shown in FIGS. 2 and 3, the floor slab P is laid by fitting the ridges 4 of the floor slab P into the concave grooves 3 of the adjacent floor slab P. Therefore, the ridges 4 of each floor panel are formed in a size that can fit into the concave grooves 3 of the adjacent floor panel. It goes without saying that the concave grooves 3 and the ridges 4 in each floor plate P have the same dimensions.
It is not impossible to make the protrusion amount X of the ridge 4 equal to the depth of the groove or to make it smaller than the depth of the groove 3. Therefore, it is desirable that the protrusion amount X be larger than the depth of the concave groove 3.
The ridge 4 has an elongated through hole 5 for drainage. Although the length of the floor plate material P is not particularly limited, it is usually standardized from about 120 cm to about 300 cm, for example, every 60 cm. Therefore, it is desirable to form a plurality of through holes 5 at a pitch of, for example, about 30 cm.
The thickness of the floor board P is preferably about 2 to 3 cm. The width dimension is not particularly limited, but various widths are possible, for example, from 7 to 8 cm to about 20 cm. Although the material is not particularly limited, a hard material such as urine from Indonesia or Ipe from Brazil is suitable.
FIG. 2 is a plan view showing a state in which a plurality of the floor boards P are laid. At the time of laying, the ridge 4 of the floor plate material adjacent to the groove 3 is fitted. However, even if the ridge 4 is fitted to the depth of the groove 3, the projection amount X of the ridge 4 Since it is larger than the depth, a drainage groove 6 is formed on the base of the ridge 4.
FIG. 3 is an enlarged cross-sectional view showing the state of the laying. FIG. 3A is a cross-sectional view of a position where there is no through-hole 5 in FIG. That is, since the projection amount X of the ridge 4 is larger than the depth of the groove 3, when the ridge 4 is fitted into the groove 3, the root portion of the ridge 4 does not completely enter the groove 3. Only the width W is left.
As described above, the remaining portion on the root side of the ridge 4 becomes the drain groove 6 in FIG. Even when the protrusion amount X of the ridge 4 is approximately the same as or smaller than the depth of the groove 3, the drain groove 6 can be formed by fitting the ridge 4 shallowly into the groove 3. If it does not fit deeply, there is a possibility that the bonding strength between adjacent floor plate members may decrease. However, there is no particular problem if the joists 9 are adhered with the adhesive 11 as shown in FIG.
FIG. 3B shows a cross section of the position of the through hole 5 in FIG. That is, since the elongated through hole 5 is formed at the base side of the ridge 4, the through hole 5 is located at the position of the drain groove 6 when the ridge 4 is fitted into the concave groove 3. As a result, the water that has flowed into the drain groove 6 from the upper surface of the floor plate will flow downward through the through hole 5 and will not accumulate in the drain groove 6 for a long time.
If the through hole 5 cannot be opened, the drainage grooves 6 may be provided at both ends with water collecting drainage grooves, and the water in each drainage groove 6 flows into the water collecting drainage grooves at both ends. It is also possible to drain to the outside via the drainage drain.
Alternatively, as shown in FIG. 4, the ridge 4 is made thinner partially or over the entire length, and a notch 8 is formed at the tip to form a bypass drainage channel, and the water in the drainage groove 6 is drained. It is also possible to guide to the lower side. That is, when the recesses 7 are formed on the upper and lower surfaces of the ridge 4, the plate thickness of the ridge 4 becomes thinner partially or over the entire length. Therefore, when the ridge 4 is fitted into the groove 3 of the adjacent floor plate, the water flowing into the drain groove 6 on the ridge 4 passes from the recess 7 on the upper surface of the ridge 4 through the notch 8 at the tip. Wrap around the concave portion 7 on the lower surface of the ridge 4. Then, it flows down.
The thin portions of the ridges 4 are provided at a pitch of, for example, about 30 cm similarly to the through holes 5. The width of the recesses 7 may be about the same as the length of the through-hole 5, for example, about 3 to 5 cm. The depth is also arbitrary, but may be, for example, 1 to 3 mm.
Instead of the recesses 7 parallel to each other on the upper and lower surfaces of the ridge 4, a tapered inclined channel as shown by chain lines 7a, 7a may be formed. Also, the concave groove 3 side may be formed in a trumpet-like shape like a chain line only at a position corresponding to the chain line concave portions 7a, 7a.
FIG. 5 is a sectional view of a fixing portion of each floor panel to a joist. Under the respective floor boards P, joists 9 are arranged at intervals of, for example, about 60 cm, and the respective floor boards P are nailed to the joists. At this time, the nail 10 is driven into the joist 9 from the corner at the base of the ridge 4 of the floor plate material located at the end and fixed. That is, as shown in FIG. 5, the nail 10 is hit on the corner and driven in the direction of the arrow a1.
Then, on the joist 9, the groove 3 side of the next adjacent floor plate P is pressed against the ridge 4 side of the floor plate material nailed earlier, and the ridge is inserted into the groove 3. By fitting the groove 4, the concave groove 3 side is supported and fixed on the convex ridge 4 side. In addition, the floor board material P can be bonded and fixed to the joist 9 with the adhesive 11, or nailing and bonding can be used together.
When the concave portions 7, 7 and the inclined concave portions 7a, 7a and the notch 8 as shown in FIG. 4 are formed over the entire length of the ridge 4, a bypass drainage channel is formed between the concave portion 3 and the entire length. Since a gap is formed, the bonding force between the concave groove 3 and the ridge 4 cannot be expected, but there is no particular problem if it is fixed to the joist 9 with the adhesive 11. As described above, when the gap is formed over the entire length, the gap can be formed to be constant by fixing the spacer 11 with the adhesive 11 in a state where the spacer member is inserted at the position to be the drain groove 6.
As shown in FIG. 5, when the nail 10 is driven from the corner at the base of the ridge 4, the head of the nail is located at the corner where the nail is retracted. Unlike the case of driving, there is no danger that the head of the nail is exposed on the floor surface to impair the appearance or protrude and cause danger.
The type of nail to be driven into the corner is not particularly limited, but stainless steel is suitable so that rust does not occur. Further, as the shape of the nail, a U nail or the like is suitable in addition to a normal nail.
As described above, when the floorboard of the present invention is laid, even if it rains on the floor surface, the drainage formed on the ridge 4 immediately between the adjacent floorboards. Since the water flows into the groove 6 and then flows down from the through hole 5 and the bypass drainage channel and is drained to the lower side, the inside of the drainage groove 6 is not flooded for a long time. As a result, it is possible to suppress the floor plate material from absorbing water and swelling, and the floor surface from warping.
The floor plate material P has a flat surface 2 on one side and an uneven surface 1 on the other side, so that the flat surface 2 and the flat surface 2 can be formed according to the installation place or the request of the owner. Either side of the uneven surface 1 can be laid upward. When the uneven surface 1 is directed upward, slippage is prevented and the entire surface is prevented from being flooded.
The floor structure according to the present invention can be applied to ships and the like, but can also be applied to building out decks, verandas, crossing corridors, docks, floating piers, and the like, and can also be applied to pens and the like. Alternatively, the present invention can be applied to physical education and sports facilities. It can also be used indoors where there is no danger of getting wet.

【The invention's effect】
As in claim 1, one side end in the longitudinal direction of the floorboard is formed in a groove shape, and the other side end is formed as a ridge having a size capable of being fitted into the groove in the adjacent floorboard. Since the amount of protrusion of the ridge is greater than the depth of the groove, when laying the floor plate, the ridge on the side is fitted into the groove of the adjacent floor plate to form the ridge. The portion that cannot be fitted into the concave groove on the base side of the slab becomes a drainage groove.
Therefore, the drain can be formed and the drain can be secured without opening a gap penetrating to the back surface between the adjacent floor boards. As a result, it is possible to effectively suppress the swelling of the floorboard material by absorbing moisture.
According to a second aspect of the present invention, a drainage through hole is formed at the base of the ridge, which cannot be fitted into the groove of the adjacent floor plate, so that when the floor plate is laid, The water that has flowed into the drain groove formed on the base side of the ridge can be effectively drained to the lower surface side by the through-hole and drained.
According to a third aspect of the present invention, one surface of the floor plate is formed flat and the other surface is formed in an uneven shape. Alternatively, according to the request of the owner, the flat surface and the uneven surface may be laid with either side facing upward.
According to a fourth aspect of the present invention, a ridge forming the other side end of an adjacent floor plate is fitted into a concave groove formed at one longitudinal side end of the floor plate, and the ridge is formed. The bottom side of the floor has a floor structure left as a drainage groove without being fitted in the concave groove, so that drainage can be secured by this drainage groove. As a result, the floorboard absorbs moisture. Swelling can be effectively suppressed.
According to a fifth aspect of the present invention, by making the amount of protrusion of the ridge larger than the depth of the groove, even if the ridge is fitted into the depth of the groove, the protrusion on the base side of the ridge is formed. Since the portion is not fitted into the concave groove but is left as a drain groove, even if the structure is such that a convex ridge is fitted to the depth of the concave groove to improve the connectivity of the adjacent floor structure, the drain groove may be used. Can be drained effectively.
According to a sixth aspect of the present invention, a drainage through-hole is formed at a root side of the ridge, which cannot be fitted into a groove of an adjacent floor plate, so that a drainage groove formed on the ridge is provided. Since the water that has flowed into the through hole easily flows downward from the through hole, drainage is more reliable.
As described in claim 7, one surface of the floor is formed flat and the other surface is formed unevenly, so that the flat surface and the floor can be formed according to the installation place or the request of the owner. It can be laid up on either side of the uneven surface, increasing the range of options.
In a floor structure in which nails are driven into the joists from the corners at the bases of the ridges, the fixed nails are not exposed on the floor surface, so that the appearance is improved. There is no danger of getting caught on nails and a safe floor structure can be realized.
