櫛状部１２は、格子２０の棒材２１の数より１つ多い数の櫛歯１３を有する。櫛状部１２の各櫛歯１３は、板状部１１に一体形成されており、板状部１１おける長手方向の一片から略垂直に立ち上がる。各櫛歯１３の先端側の両角は、面取りがなされている。 The comb-shaped portion 12 has a number of comb teeth 13 that is one more than the number of rods 21 of the lattice 20. Each comb tooth 13 of the comb-shaped portion 12 is integrally formed with the plate-shaped portion 11, and rises substantially vertically from a piece in the longitudinal direction of the plate-shaped portion 11. Both corners on the tip side of each comb tooth 13 are chamfered.

櫛状部１２では、各櫛歯１３が略矩形の板状に形成されている。各櫛歯１３の長さは互いに等しい。また、板状部１１の長手方向における両端の櫛歯１３を除く３本の櫛歯１３は、幅が互いに等しく、格子２０における棒材２１間の隙間を規定する。また、板状部１１の長手方向における両端の櫛歯１３は、幅が互いに等しい。なお、複数の櫛歯１３における幅寸法の関係は、本実施形態に限定されず、格子２０の設計に応じて任意に設定することができる。 In the comb-shaped portion 12, each comb tooth 13 is formed in a substantially rectangular plate shape. The lengths of the comb teeth 13 are equal to each other. Further, the three comb teeth 13 excluding the comb teeth 13 at both ends in the longitudinal direction of the plate-shaped portion 11 have the same width as each other, and define the gap between the bar members 21 in the lattice 20. Further, the widths of the comb teeth 13 at both ends of the plate-shaped portion 11 in the longitudinal direction are equal to each other. The relationship between the width dimensions of the plurality of comb teeth 13 is not limited to this embodiment, and can be arbitrarily set according to the design of the lattice 20.

複数の棒材固定用貫通孔１１ａは、図１（ａ）に示すように、板状部１１の長手方向に沿って間隔を空けて並んでいる。各棒材固定用貫通孔１１ａは、図１（ｂ）に示すように、櫛歯１３が立ち上がる方とは反対側に広がるように形成された皿穴である。各棒材固定用貫通孔１１ａは、隣り合う櫛歯１３間の隙間１４に挿入された各棒材２１が当接する領域（板状部１１の長手方向において隙間１４に対応する領域）に形成されている。 As shown in FIG. 1A, the plurality of bar member fixing through holes 11a are arranged at intervals along the longitudinal direction of the plate-shaped portion 11. As shown in FIG. 1B, each bar fixing through hole 11a is a countersunk hole formed so as to expand on the side opposite to the side on which the comb teeth 13 stand up. Each bar fixing through hole 11a is formed in a region where each bar 21 inserted in the gap 14 between adjacent comb teeth 13 abuts (a region corresponding to the gap 14 in the longitudinal direction of the plate-shaped portion 11). ing.

複数の格子固定用貫通孔１１ｂは、板状部１１の長手方向に沿って間隔を空けて並んでいる。格子固定用貫通孔１１ｂの位置は、棒材固定用貫通孔１１ａの位置に対し板状部１１の幅方向にずれている。各棒材固定用貫通孔１１ａは、深さ方向に直径が一定の穴である。各棒材固定用貫通孔１１ａは、格子２０が完成した状態で隙間１４の各々に挿入された棒材２１が何れも当接しない領域（板状部１１の長手方向において櫛歯１３に対応する領域）に形成されている。 The plurality of lattice fixing through holes 11b are arranged at intervals along the longitudinal direction of the plate-shaped portion 11. The position of the grid fixing through hole 11b is deviated from the position of the bar fixing through hole 11a in the width direction of the plate-shaped portion 11. Each bar fixing through hole 11a is a hole having a constant diameter in the depth direction. Each bar fixing through hole 11a corresponds to a comb tooth 13 in the longitudinal direction of the plate-shaped portion 11 in a region where none of the bar 21 inserted into each of the gaps 14 abuts when the lattice 20 is completed.

［格子用金具の使用方法］
格子用金具１０を用いた格子２０の製作方法について説明を行う。 [How to use the grid metal fittings]
A method of manufacturing the lattice 20 using the lattice metal fitting 10 will be described.

格子用金具１０を用いて格子２０を製作する際は、図２（ａ）に示すように、格子２０を構成する複数の棒材２１について、両端の位置を揃え、且つ、間隔を空けて、床などの平坦面上に並べる。そして、各櫛歯１３の先端側を下側に向けて、複数の棒材２１の上方に格子用金具１０を持っていき、隣り合う棒材２１間の隙間の各々に、各櫛歯１３が挿入されるように、格子用金具１０を下側に移動させる。格子用金具１０は、図２（ｂ）に示すように、板状部１１の下面が各棒材２１の上面に当接する状態になるまで下側に移動させる。 When the lattice 20 is manufactured by using the lattice metal fitting 10, as shown in FIG. 2A, the positions of both ends of the plurality of rods 21 constituting the lattice 20 are aligned and spaced apart from each other. Arrange on a flat surface such as the floor. Then, with the tip end side of each comb tooth 13 facing downward, the lattice metal fittings 10 are brought above the plurality of bar members 21, and each comb tooth 13 is placed in each of the gaps between the adjacent bar members 21. The grid fitting 10 is moved downward so that it can be inserted. As shown in FIG. 2B, the lattice metal fitting 10 is moved downward until the lower surface of the plate-shaped portion 11 comes into contact with the upper surface of each bar 21.

この状態で、各棒材固定用貫通孔１１ａに対しビス１５（固定部品）をそれぞれ通し、各ビス１５を棒材２１にねじ込む。これにより、各棒材２１が板状部１１に固定される。 In this state, the screws 15 (fixing parts) are passed through the through holes 11a for fixing the rods, and the screws 15 are screwed into the rods 21. As a result, each bar 21 is fixed to the plate-shaped portion 11.

格子２０は、図３に示すように、床３０の開口部３１に取り付けることにより、通風口３２を形成することができる。具体的に、図３では、大引き（又は根太）などの床下構造物３５（格子２０の取付対象物）上に、下地合板３６とフローリング材３７（例えば、無垢材）が下側から順番に積層されている。そして、下地合板３６とフローリング材３７に、床下構造物３５が横断するように矩形の開口部３１が形成されている。床下構造物３５上には、高さ調節用のパッキン３８を介して、格子用金具１０側が下側となるように格子２０が設置されている。また、各格子固定用貫通孔１１ｂには、ビス１５（固定部品）がそれぞれ通されて、パッキン３８を介して、床下構造物３５に各ビス１５がねじ込まれている（図示省略）。 As shown in FIG. 3, the grid 20 can form the ventilation port 32 by attaching it to the opening 31 of the floor 30. Specifically, in FIG. 3, the base plywood 36 and the flooring material 37 (for example, solid wood) are sequentially placed on the underfloor structure 35 (object to be attached to the lattice 20) such as a large pull (or joist) from the bottom. It is laminated. A rectangular opening 31 is formed in the base plywood 36 and the flooring material 37 so as to cross the underfloor structure 35. A grid 20 is installed on the underfloor structure 35 via a packing 38 for height adjustment so that the grid metal fitting 10 side is on the lower side. Further, screws 15 (fixing parts) are passed through the through holes 11b for fixing each lattice, and each screw 15 is screwed into the underfloor structure 35 via the packing 38 (not shown).

［本実施形態の効果等］
本実施形態では、格子２０における棒材２１のピッチが、格子用金具１０における櫛歯の幅寸法により決まる。そのため、格子用金具１０を予め準備しておけば、棒材２１のピッチを設計値にするための加工を格子２０の構成材に対し行うことなく、櫛歯１３間の隙間１４の各々に棒材２１を挿入するだけで、棒材２１のピッチを設計値に容易に合わせることができる。また、板状部１１の棒材固定用貫通孔１１ａを利用して、板状部１１に棒材２１を容易に固定することができる。本実施形態によれば、現場において格子２０を容易にしかも安価に製作することができる。また、床の色に格子２０の色が合うように、見切り材を用いて、工務店で容易に格子２０を製作できるようにもなる。 [Effects of this embodiment, etc.]
In the present embodiment, the pitch of the bar 21 in the lattice 20 is determined by the width dimension of the comb teeth in the lattice fitting 10. Therefore, if the grid metal fittings 10 are prepared in advance, the rods are formed in each of the gaps 14 between the comb teeth 13 without processing for setting the pitch of the bar 21 to the design value for the constituent members of the grid 20. The pitch of the bar 21 can be easily adjusted to the design value simply by inserting the material 21. Further, the bar 21 can be easily fixed to the plate 11 by using the bar fixing through hole 11a of the plate 11. According to this embodiment, the grid 20 can be easily and inexpensively manufactured in the field. Further, the grid 20 can be easily manufactured at the construction shop by using the parting material so that the color of the grid 20 matches the color of the floor.

また、本実施形態では、各棒材２１が、２本の櫛歯１３により挟まれて回転が拘束される。ここで、複数の棒材の各々を直交する部材にビス止めしただけでは、棒材が反ったり捩じれたりする。それに対し、本実施形態では、各棒材２１が回転できないため、反りやねじれが軽減される。また、格子用金具１０を介して複数の棒材２１が一体化される。本実施形態によれば、格子２０の強度を向上させることもできる。 Further, in the present embodiment, each bar 21 is sandwiched between the two comb teeth 13 to restrain the rotation. Here, if each of the plurality of rods is simply screwed to an orthogonal member, the rods will warp or twist. On the other hand, in the present embodiment, since each bar 21 cannot rotate, warpage and twist are reduced. Further, a plurality of bar members 21 are integrated via the lattice metal fitting 10. According to this embodiment, the strength of the grid 20 can be improved.

［その他の実施形態］
上述の実施形態において、棒材２１は、角材に限定されず、例えば円形断面の棒材を用いてもよい。また、棒材２１に、金属製や樹脂製の棒材を用いてもよい。 [Other Embodiments]
In the above-described embodiment, the bar 21 is not limited to the square bar, and for example, a bar having a circular cross section may be used. Further, a metal or resin bar may be used as the bar 21.

上述の実施形態において、格子２０はルーバーであってもよい。 In the above embodiment, the grid 20 may be a louver.

上述の実施形態では、各貫通孔１１ａ，１１ｂに通す固定部品がビスであったが、ネジ又は釘など他のものであってもよい。また、各貫通孔１１ａ，１１ｂの代わりに、棒材固定用挿通部又は格子固定用挿通部を切欠きとしてもよい。 In the above-described embodiment, the fixing component to be passed through the through holes 11a and 11b is a screw, but other parts such as a screw or a nail may be used. Further, instead of the through holes 11a and 11b, a bar material fixing insertion portion or a grid fixing insertion portion may be used as a notch.
