  The present invention relates to a fixing structure for a floor material constituting a wood deck or the like.

  As shown in FIG. 6, each floor material a adjacent to each other of long plate-like floor materials a laid at regular intervals on a support material b made of a joist is used as the floor material fixing structure. There has already been proposed a configuration in which opposing side edges of a are connected by a connector c and each flooring a is fixed to a support material b by the connector c (see Patent Document 1).

In such a floor material fixing structure, each floor material a has fitting grooves d and d formed of substantially horizontal cut grooves at predetermined height positions on both side end surfaces along the longitudinal direction.

  By the way, in the flooring material a used in the above-described fixing structure, both side edges located below the fitting grooves d, d at the mid-depth positions of the fitting grooves d, d formed on both side end surfaces, respectively. Since the cutout recesses e and e that are continuous with the fitting grooves d and d are formed on the left and right edges of the flooring material a, respectively, there is a problem in that the processing is troublesome.

  Moreover, in the connector c used for the fixing structure mentioned above, it is inserted into the insertion hole k from above with one fitting piece h fitted in the fitting groove d of one flooring a. When the fixing screw j is screwed to fix the connecting member c to the support member b, the insertion hole k is exposed to the upper side so that the insertion hole k is exposed upward and the fixing screw j can be screwed. The width of the bottom plate portion f needs to be increased in accordance with the deviation size by forming it at a position biased laterally from the central portion of the metal plate. Therefore, the metal plate constituting the connector c There is a problem that the amount of use increases and the cost increases.

  Furthermore, in the fixing structure described above, the fitting pieces h and h of the coupler c fixed to the support material b are fitted into the fitting grooves d and d facing each other of the adjacent floor materials a and a. Since both floor materials a and a are only held, both floor materials a and a are easily displaced in the longitudinal direction. In order to prevent this displacement, actually, at least one location for each floor material a is separately provided. Therefore, it has been necessary to prevent the displacement of each floor material a by screwing a fixing screw into the support material b from the surface of the floor material a. For this reason, since the head of the fixing screw is exposed on the surface of the floor material a, there is a problem that the aesthetic appearance is lowered.

  It is an object of the present invention to provide a flooring fixing structure that can eliminate such conventional problems.

  In the present invention, a long flat plate-like floor material constituting a floor surface is laid on a support material at regular intervals, and opposing side edges of the floor materials adjacent to each other are connected by a connector, and the connection In the fixing structure of the floor material fixed to the support material by the tool, a substantially horizontal cut groove of the same depth is formed at a predetermined height position on both side end surfaces along the longitudinal direction, and one of the cut grooves is the first groove. A floor having a fitting groove, a side edge located below the notch groove at the middle depth of the other notch groove to form a notch recess, and the remaining notch groove as a second fitting groove Material, bottom plate portion, left and right side plate portions raised substantially vertically from the left and right ends of the bottom plate portion to a height position corresponding to the distance between the bottom surface of the floor material and the cut groove, and one side plate portion Wide fitting piece that extends substantially horizontally outward from the upper end of the first fitting groove and can be fitted into the first fitting groove A narrow-width fitting piece portion that extends substantially horizontally outward from the upper end of the other side plate portion and can be fitted into the second fitting groove, and has a substantially crank-shaped cross section, and the wide-width fitting. The length of the side plate portion provided with the joining piece portion is lengthened to form a protruding edge portion protruding in the front-rear direction from the end portion of the other side plate portion, and a nail is formed between the protruding edge portion and the substantially central portion of the bottom plate portion. Or a coupling tool formed with insertion holes through which fastening members made of fixing screws are formed, and the wide fitting piece is fitted into the first fitting groove of one adjacent flooring. The connecting member is fixed to the support member by the fixing member inserted through the insertion hole of the bottom plate portion, and the connecting member is fixed to the side end surface of the one floor material by the fixing member inserted through the insertion hole of the protruding edge portion. The coupling tool is substantially housed in the notch recess of the other adjacent flooring, and the narrow fitting piece of the coupling tool is A fixed structure of flooring, characterized in that fitted in the second fitting groove of the flooring by fixing the flooring.

  Here, natural wood or synthetic wood processed into a long flat plate shape can be used for the flooring, and the first fitting groove, the second fitting groove and the notch are formed on the natural wood or synthetic wood. The formation process of a recessed part is given. On the other hand, the connecting tool can be manufactured by punching a metal plate into a predetermined shape and then bending the metal plate into a substantially crank shape.

  Further, in the above-described configuration, a configuration is proposed in which the flooring is a hollow flat plate-like synthetic wood having a predetermined thickness and a plurality of reinforcing ribs that are parallel to each other across the thickness. The

  Here, synthetic wood is obtained by mixing and melting a synthetic resin such as wood powder and polypropylene and an organic reinforcing agent, and extruding it into a hollow plate material. Such synthetic wood is lightweight and has high dimensional accuracy. There is an advantage that it has good aesthetics because it has substantially the same strength and cutting workability as natural wood and has a wood texture.

  As described above, according to the present invention, a substantially horizontal cut groove having the same depth is formed at a predetermined height position on both side end faces along the longitudinal direction, and the cut groove is formed at a midway depth position of the cut groove. By using a long plate-like floor material in which the side edge located below is cut out to form a notch recess, it is only necessary to form a notch recess only on one side edge of the floor material, as in the past. Compared with the case where the notched recesses e and e (see FIG. 6) are formed on both side edges, the forming process is simpler, and it takes less time and effort, so the processing efficiency is improved. Here, if the floor material is made of synthetic wood and extrusion molding is performed with a cross-sectional shape having a predetermined fitting groove and a notch recess, the above-described forming process of the notch groove and notch recess becomes unnecessary, but extrusion molding For the production of small molds for flooring, fitting grooves and notch recesses were formed on commercially available general-purpose synthetic wood. The manufacturing cost can be greatly reduced.

  Further, in the present invention, cut grooves having the same depth are respectively formed on both end surfaces of the flooring material. Thus, by making both the cut grooves have the same depth, cut grooves having different depths are formed. Compared with the case where the left and right side end surfaces are separately formed, it is not necessary to adjust the cutting depth of the cutting rotary teeth for each of the left and right cut grooves, so that the work efficiency is improved. In this way, one of the cut grooves formed at the same depth on both end faces is used as the first fitting groove, and the side edge located below the cut groove in the middle depth position of the other cut groove. And forming a notch recess to make the remaining cut groove a second fitting groove, a connecting tool, a wide fitting piece that can be fitted into the first fitting groove, and the second fitting groove By providing the narrow fitting piece that can be fitted in the fitting groove, the wide fitting piece and the narrow fitting are provided for the first fitting groove and the second fitting groove having different depths. The combined pieces can be fitted to each other in a uniform manner, whereby a stable fixed state can be obtained.

  Further, the wide fitting piece is fitted into the first fitting groove of one floor material, and the outer side surface of the side plate portion provided with the wide fitting piece is brought into contact with the side end surface of the floor material. As a result, the bottom plate portion of the connector protrudes to the side of the flooring, and the insertion hole formed in the substantially central portion of the bottom plate portion is exposed upward, and the fastening member inserted through the insertion hole is stopped. The wearing operation can be easily performed. As a result, the width dimension of the bottom plate portion can be reduced as compared with the case where the insertion hole k (see FIG. 7) is formed at a position that is deviated laterally from the center portion of the bottom plate portion as in the prior art. Since the usage amount of the metal plate constituting the coupler is reduced, the material cost can be reduced.

  Moreover, after fixing a connection tool to a supporting material with the fastening member inserted in the insertion hole of the baseplate part in the state which fitted the wide fitting piece part to the 1st fitting groove of one flooring, a protrusion edge part By fixing the connector to the side end surface of the one floor material by the fastening member inserted through the insertion hole, it is possible to prevent the floor material from being displaced in the longitudinal direction via the connector. Here, since the fastening member inserted through the insertion hole of the protruding edge portion is fastened to the side end surface of the floor material, the fastening member is not exposed to the surface of the floor material after construction. As a result, it is possible to eliminate a decrease in aesthetics due to the head of the fixing screw being exposed on the surface of the floor material as in the prior art.

  Further, in the configuration in which the flooring is a hollow flat synthetic wood having a predetermined thickness and a plurality of mutually parallel reinforcing ribs crossing the thickness at predetermined intervals, the floor material is abbreviated as natural wood. The same machinability can be obtained, the dimensional accuracy is excellent, the weight can be reduced to a predetermined level, and the woody texture is provided, resulting in good aesthetics.

Below, one Example of the fixing structure of the flooring concerning this invention is described based on FIGS.
As shown in FIG. 1 (a), the flooring 1 is formed of a hollow flat plate-shaped synthetic wood having a predetermined thickness and a plurality of reinforcing ribs 2 that are parallel to each other across the thickness. . The synthetic wood is made by mixing and melting wood flour (about 55% by weight), a synthetic resin such as polypropylene (about 45% by weight), and an organic reinforcing agent (about 0.5% by weight). The cross-sectional shape shown in FIG. Extruded as a hollow plate from a die having a considerable slit, and a general-purpose commercial product with a fixed length of about 4 m cut into a predetermined length (for example, about 2 m) as required is used as the material. It has been. Various widths of the synthetic wood are sold, and can be selected as appropriate from these.

  Note that the material of the flooring 1 is not limited to the synthetic wood as described above, and a long flat plate-like natural wood can also be used. By using the synthetic wood, cutting substantially the same as the natural wood is possible. Workability can be obtained, the dimensional accuracy is excellent, the weight can be reduced to a predetermined level, and the appearance is good due to the woody texture. Here, since the synthetic wood has a hollow flat plate shape, it is lighter than a solid wood having the same thickness.

  As shown in FIG. 1 (b), the both side end faces 3, 3 along the longitudinal direction of the flooring 1 have cut grooves 4 a having substantially the same depth at a height position that bisects the thickness. 4b is formed, and one cut groove 4a serves as the first fitting groove 5. Further, the side edge located below the notch groove 4b is cut off at the middle depth position of the other notch groove 4b to form a notch recess 6 as shown in FIG. The notch groove 4 b is the second fitting groove 7. Further, chamfering 8, 8 is performed on the ridges along the longitudinal direction on the upper surface side of the flooring 1 as necessary.

  On the other hand, the connector 9 is made of a metal plate having excellent corrosion resistance. As shown in FIGS. 2 and 3, the connector 9 has a bottom plate portion 10, and left and right portions raised substantially vertically from the left and right ends of the bottom plate portion 10. Side plate portions 11a and 11b, a wide fitting piece portion 12 extending approximately horizontally outward from the upper end of one side plate portion 11a, and extending approximately horizontally outward from the upper end of the other side plate portion 11b. As shown in FIG. 2 (a), the narrow-width fitting piece portion 13 is formed into a substantially crank-shaped cross section, and further, the longitudinal length of the side plate portion 11a provided with the wide-width fitting piece portion 12 The protruding edge portions 14 and 14 protrude in the front-rear direction from the end portion of the other side plate portion 11b, and a nail or a fixing screw is provided between the protruding edge portions 14 and 14 and the substantially central portion of the bottom plate portion 10. Insertion holes 16a and 16b through which fastening members 15 (see FIG. 4) made of That. Here, the height of the side plate portions 11a and 11b is set to be a height corresponding to the distance between the bottom surface of the flooring 1 and the cut grooves 4a and 4b, and the wide fitting piece portion. The width of 12 is set to correspond to the depth of the first fitting groove 5, and the width of the narrow fitting piece 13 corresponds to the depth of the second fitting groove 7. It is set to be the width to be.

  Next, the construction procedure will be described. First, as shown in FIG. 4A, the wide fitting piece 12 of the connector 9 is fitted into the first fitting groove 5 of one flooring 1 on the support member 17 made of joist. When the outer side surface of the side plate portion 11 a having the wide fitting piece 12 is brought into contact with the side end surface of the floor material 1, the bottom plate portion 10 of the connector 9 protrudes to the side portion of the floor material 1 and the bottom plate The insertion hole 16b formed in the substantially central portion of the portion 10 is exposed upward. In this state, as shown in FIG. 4B, the fastening member 15 made of a fixing screw inserted from above into the insertion hole 16 b of the bottom plate portion 10 is screwed to fix the connector 9 to the support member 17. Next, a fastening member 15 made of a fixing screw inserted from the side is inserted into the insertion hole 16a of the protruding edge 14, and the connecting tool 9 is connected to the side of the one flooring 1 as shown in FIG. 4 (c). Secure to the end face. Here, two insertion holes 16a of the projecting edge portion 14 are provided at the front and rear end portions of the side plate portion 11a, so that it is possible to select the one that is easy to work according to the dominant arm of the operator. If the fastening member 15 is screwed into any one of the insertion holes 16a, a sufficient fixing action can be obtained. As a result, the flooring 1 is fixed to the support member 17 via the connector 9 and does not shift in the longitudinal direction. Thereafter, as shown in FIG. 4 (d), the connector 9 is substantially stored in the notch recess 6 of the other adjacent flooring 1, and the narrow fitting piece 13 of the connector 9 is moved to the other side. It fits into the second fitting groove 7 of the flooring 1.

  Then, such a fixing operation is repeated for each of the adjacent floor materials 1 and 1, and as shown in FIG. 5, as shown in FIG. 5, the long flat plate floor materials 1 laid on the support material 17 at regular intervals. Fixing the flooring according to the present invention by connecting opposing side edges of the flooring materials 1 and 1 adjacent to each other by the connecting tool 9 and fixing the flooring material 1 to the support member 17 by the connecting tool 9. The structure is structured.

  In such a configuration, the flooring 1 only needs to form the notch recess 6 only on one side edge thereof, so that the notch recess e and e (see FIG. 6) are formed on both side edges as in the prior art. Compared to the case, the forming process is simple, and it takes less time and effort, so the processing efficiency is improved.

  Further, since the cut grooves 4a and 4b formed on the both end surfaces of the flooring 1 have the same depth, cutting grooves with different depths are formed for cutting as compared with the case where the cut grooves having different depths are separately formed on the left and right side end surfaces. Since it is not necessary to adjust the cutting depth of the rotating teeth for each of the left and right cut grooves 4a and 4b, the working efficiency is improved. In this way, one of the cut grooves 4a and 4b formed at the same depth on both side end faces is used as the first fitting groove 5, and the lower cut groove 4b is positioned below the cut groove 4b at the midway depth position of the other cut groove 4b. The side edge located at the top is cut away to form a notch recess 6, and the remaining cut groove 4 b is used as the second fitting groove 7, while the connector 9 can be fitted into the first fitting groove 5. By providing the wide fitting piece 12 and the narrow fitting piece 13 that can be fitted into the second fitting groove 7, the first fitting groove 5 and the second fitting having different depths are provided. The wide fitting piece 12 and the narrow fitting piece 13 can be fitted to the groove 7 in a uniform manner, whereby a stable fixed state of the flooring 1 can be obtained.

  Moreover, the said wide fitting piece part 12 is fitted to the 1st fitting groove | channel 5 of one flooring 1, and the side-plate part 11a provided with the said wide fitting piece part 12 in the side end surface of this flooring 1 is shown. Since the bottom plate portion 10 of the connector 9 protrudes to the side portion of the flooring 1 and the insertion hole 16b formed in the substantially central portion of the bottom plate portion 10 is exposed upward when the outer side surface of the connector 9 is brought into contact. The fastening operation of the fastening member 15 inserted through the insertion hole 16b can be easily performed. Thereby, the width dimension of the baseplate part 10 can be made small compared with the case where the insertion hole k (refer FIG. 7) is formed in the position biased laterally from the center part of the baseplate part like the past. In addition, since the amount of the metal plate constituting the connector 9 is reduced, the material cost can be reduced.

  In addition, the connecting member 9 is fixed to the side end surface of one flooring material 1 by the fastening member 15 inserted through the insertion hole 16 a of the protruding edge portion 14. Directional deviation can be prevented. Here, since the fastening member 15 inserted through the insertion hole 16a of the protruding edge portion 14 is fastened to the side end surface of the flooring 1, the fastening member 15 may be exposed on the surface of the flooring 1 after construction. Without this, it is possible to eliminate a decrease in aesthetics due to the head of the fixing screw being exposed to the surface of the floor material as in the prior art.

  Moreover, when using a hollow plate-like synthetic wood having a predetermined thickness and a plurality of parallel reinforcing ribs 2 crossing the thickness at predetermined intervals, the floor material 1 While substantially the same machinability can be obtained, the dimensional accuracy is excellent and the light weight having a predetermined strength can be obtained, and the wood texture is provided, so that the aesthetics are good.
