一般に根太に板材を取り付けて形成する直貼り式の形態は、根太と横切る方向に板材を配置し、根太と板材とが交差する部位で固定用の部材を用いて固定している。固定作業に際しては、板材の表面に釘やボルト等の締結手段が表れた状態では外観上見苦しく、また引っかかる恐れがあることから、板材の厚みを大きいものとし、板材の側端下方に突出部を設け、固定用の部材と根太との間に突出部を挟んで固定することで、固定が容易で締結手段が表面に表れることがない板材の固定構造が用いられてきている。 Generally, in the direct-attached form in which a plate material is attached to a joist, the plate material is arranged in a direction crossing the joist and fixed by using a fixing member at a portion where the joist and the plate material intersect. In the fixing work, if the fastening means such as nails and bolts are exposed on the surface of the plate material, it looks unsightly and there is a risk of getting caught. A plate material fixing structure has been used in which fixing is easy and the fastening means does not appear on the surface by providing and fixing by sandwiching a protruding portion between the fixing member and the joist.

かかる直貼り式の形態については、例えば根太と、根太の上部に固定される台座部、及びこの台座部の上部に左右向きに形成される翼部からなり、上記台座部を通過して上下に貫通するビス孔が穿設された固定具と、上記根太間に並置される長尺板材からなり、両側部にはそれぞれ上記固定具の翼部の介在が可能な収納凹部が形成され、上記両側部の下部には突出部がそれぞれ形成されたデッキ材とを有し、隣接する上記デッキ材間の両収納凹部により形成された空間部に上記固定具の翼部を介在させるとともに、この固定具の台座部に両側からそれぞれ上記デッキ材の各突出部を当接させて配置し、上記両デッキ材の上部間に形成された隙間から工具を差し込んで上記固定具のビス孔にビスを螺設し、この固定具とともに上記デッキ材を上記根太の上部に固定したことを特徴とするデッキ材取付構造が開示されている（例えば特許文献２）。 The direct-attached form is composed of, for example, a joist, a pedestal portion fixed to the upper part of the joist, and a wing portion formed in the upper part of the pedestal portion in the left-right direction, and passes through the pedestal portion to move up and down. It is composed of a fixture with a penetrating screw hole and a long plate material juxtaposed between the joists. The lower part of the portion has a deck material on which a protruding portion is formed, and the wing portion of the fixture is interposed in a space formed by both storage recesses between the adjacent deck materials, and the fixture is formed. Each of the protruding parts of the deck material is placed in contact with the pedestal portion of the above deck material from both sides, and a tool is inserted through the gap formed between the upper portions of the deck material and screws are screwed into the screw holes of the fixture. However, a deck material mounting structure characterized in that the deck material is fixed to the upper part of the joist together with the fixture is disclosed (for example, Patent Document 2).

The other plate material is formed from its side end portion toward the side, and has a downward projecting portion having an inclined receiving surface whose upper surface faces diagonally upward with respect to the side.
The lower protruding portion of the other plate material is locked in the storage space formed between the locking portion of the fixing member and the joist.
Wherein with plate comprises a metallic core, the lower protrusion is formed in the core,
It is characterized in that a downward protruding portion formed of the core material is arranged between a locking portion of the fixing member formed of an aluminum alloy shaped material and a joist.

本発明によれば、固定部材は、隣合う板材同士に対して、一方の板材に取付けられる取付部と、他方の板材を係止する係止部と、根太上に固定具を介して固定される固定部とを備え、前記他方の板材は、その側端部から側方に向けて形成され、その上面が側方に対して斜め上方に面する傾斜受け面を有する下突出部を備え、前記固定部材の係止部と根太との間に形成された収納空間内で他の板材の下突出部が係止されているので、固定部材によって根太上に一方の板材を固定した後に、他方の板材は下突出部を収納空間内に係止するだけでよく、そして、この操作を繰り返すことによって、複数の板材を根太上に並べて固定することができる。 According to the present invention, the fixing member is fixed to adjacent plate materials via a fixture, a mounting portion to be attached to one plate material, a locking portion for locking the other plate material, and a joist. The other plate material is formed from a side end portion thereof to a side surface, and has a downward projecting portion having an inclined receiving surface whose upper surface faces diagonally upward with respect to the side surface. Since the lower protruding portion of the other plate material is locked in the storage space formed between the locking portion of the fixing member and the joist, after fixing one plate material on the joist by the fixing member, the other plate material is locked. It is only necessary to lock the lower protruding portion of the plate material in the storage space, and by repeating this operation, a plurality of plate materials can be arranged and fixed on the joist.

本発明において、固定部材の係止部の先端部と下突出部の基端部との間には隙間が形成されると共に、係止部の下側面部と下突出部との間に隙間が形成されるように構成しておけば、固定部材が取付けられている板材の側端部を持ち上げると、下突出部の係止状態が緩んで隙間が生じるため、隙間を少なくする方向に板材を移動すると、該板材の係止状態が緩み、これを繰り返すことによって、該板材を取り外すことができる。 In the present invention, a gap is formed between the tip end portion of the locking portion of the fixing member and the base end portion of the lower protruding portion, and a gap is formed between the lower side surface portion and the lower protruding portion of the locking portion. If it is configured to be formed, when the side end of the plate material to which the fixing member is attached is lifted, the locked state of the lower protrusion is loosened and a gap is created. When the plate material is moved, the locked state of the plate material is loosened, and by repeating this, the plate material can be removed.

また、本発明において、固定部材の係止部の下側面部は、下方に向かうほど係止部の中央側へ切り欠かれた切欠部を有しており、板材の左下突出部の突出先端部に対して、下方に向かうほど左右方向の離間寸法を大きくしておけば、固定部材が取付けられている板材の側端部を持ち上げると、下突出部の係止状態が緩んだ際、隙間が大きくなりやすいため、板材を取り外しやすくなる。 Further, in the present invention, the lower side surface portion of the locking portion of the fixing member has a notch portion notched toward the center side of the locking portion toward the lower side, and the protruding tip portion of the lower left protruding portion of the plate material. On the other hand, if the separation dimension in the left-right direction is increased toward the bottom, when the side end of the plate material to which the fixing member is attached is lifted, a gap will be created when the locked state of the lower protrusion is loosened. Since it tends to be large, it is easy to remove the plate material.

次に、本発明を実施するための最良の形態について図面を参照し、具体的に説明する。 Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

図１は、本発明に係わる板材の固定構造に用いられる固定部材の、実施の一形態を示す説明図であって、（ａ）は正面図、（ｂ）は平面図、（ｃ）は（ｂ）のＡ−Ａ線の断面図である。固定部材１は、斜め方向に延びる二本の腕部同士が接続された略Ｖ字状の断面形状であって、略Ｖ字状の一方の腕部が取付部１１、他方の腕部が係止部１２であって、取付部１１と係止部１２とを接続する固定部１３とを備えている。取付部１１は厚さ方向に貫通する貫通孔１１ａを有し、固定部１３は上下方向に貫通する貫通孔１３ａを有している。 1A and 1B are explanatory views showing an embodiment of a fixing member used in the fixing structure of a plate material according to the present invention, in which FIG. 1A is a front view, FIG. 1B is a plan view, and FIG. It is sectional drawing of the line AA of b). The fixing member 1 has a substantially V-shaped cross-sectional shape in which two arms extending in an oblique direction are connected to each other, and one of the substantially V-shaped arms is engaged with the mounting portion 11 and the other arm is engaged. The stop portion 12 includes a fixing portion 13 for connecting the mounting portion 11 and the locking portion 12. The mounting portion 11 has a through hole 11a penetrating in the thickness direction, and the fixing portion 13 has a through hole 13a penetrating in the vertical direction.

図２は、固定部材１を介して根太２に固定された板材３において固定部材１付近の縦断面図である。根太２上には、二個の板材３が幅方向である左右方向に隙間をあけて配置されており、隣合う板材３の間に固定部材１が位置している。固定部材１は、固定部１３の貫通孔１３ａに挿通されたビス１４によって根太２上に固定されている。隣合う板材３の隙間の左右方向の間隔は、特に限定されるものではないが、作業者が板材３上から固定部材１の固定作業や取り外し作業ができることが好ましく、具体的には、固定部材１の固定部１３のビス１４を締結したり、緩めたりするためのドライバー等の工具が入るものであればよい。 FIG. 2 is a vertical cross-sectional view of the plate material 3 fixed to the joist 2 via the fixing member 1 in the vicinity of the fixing member 1. Two plate members 3 are arranged on the joist 2 with a gap in the left-right direction, which is the width direction, and the fixing member 1 is located between the adjacent plate members 3. The fixing member 1 is fixed on the joist 2 by a screw 14 inserted into the through hole 13a of the fixing portion 13. The distance between the gaps between the adjacent plate members 3 in the left-right direction is not particularly limited, but it is preferable that the operator can perform the fixing work and the removal work of the fixing member 1 from above the plate material 3, specifically, the fixing member. Any tool such as a screwdriver for fastening or loosening the screw 14 of the fixing portion 13 of 1 may be inserted.

隣合う二個の板材３のうち、一方の板材３は固定部材１の取付部１１に取付けられており、他方の板材３は、その側端部から側方に向けて形成された下突出部３１を有しており、下突出部３１は、固定部材１の係止部１２と根太２との間に形成された収納空間４内に配置されている。 Of the two adjacent plate materials 3, one plate material 3 is attached to the attachment portion 11 of the fixing member 1, and the other plate material 3 is a downward protruding portion formed from its side end portion toward the side. 31 is provided, and the lower protruding portion 31 is arranged in a storage space 4 formed between the locking portion 12 of the fixing member 1 and the joist 2.

次に、板材の固定構造について、図３〜図５に基づき更に詳しく説明する。一般には、根太２上に板材３を左右方向に複数並設する場合は、並設する板材３の左右方向の一方の端部に位置する板材３を根太２上に固定し、続いて隣合う板材３を順に取り付ける、いわゆる、片追い型の固定方法が用いられることが多いため、以下もこの固定方法に従って説明するが、特にこの方法に限定されるものではない。なお、図３〜図９に記載された板材３の下突出部３１において、便宜上、右側の下突出部３１を右下突出部３１ａ、左側の下突出部３１を左下突出部３１ｂとして説明する。 Next, the fixing structure of the plate material will be described in more detail with reference to FIGS. 3 to 5. Generally, when a plurality of plate materials 3 are arranged side by side on the joist 2 in the left-right direction, the plate materials 3 located at one end of the plate materials 3 arranged side by side in the left-right direction are fixed on the joist 2 and subsequently adjacent to each other. Since a so-called one-sided fixing method in which the plate members 3 are attached in order is often used, the following will also be described according to this fixing method, but the method is not particularly limited to this method. In the lower protruding portion 31 of the plate material 3 shown in FIGS. 3 to 9, for convenience, the lower protruding portion 31 on the right side will be referred to as the lower right protruding portion 31a, and the lower protruding portion 31 on the left side will be referred to as the lower left protruding portion 31b.

図３は、左右方向に複数並設された板材の左側端部に配置される板材の固定構造を示す説明図である。まず、根太２上に板材３を配置し、固定部材１を介して板材３の一方の側端部を根太２に固定する。本形態では、板材３は、その左右の両側端部に下突出部３１を有しており、下突出部３１は、その上面が側方に対して斜め上方に面する傾斜受け面部３２を有している。 FIG. 3 is an explanatory view showing a fixing structure of the plate materials arranged at the left end portion of a plurality of plate materials arranged side by side in the left-right direction. First, the plate material 3 is arranged on the joist 2, and one side end portion of the plate material 3 is fixed to the joist 2 via the fixing member 1. In the present embodiment, the plate material 3 has downward projecting portions 31 at both left and right end portions thereof, and the downward projecting portion 31 has an inclined receiving surface portion 32 whose upper surface faces diagonally upward with respect to the side. is doing.

右下突出部３１ａの傾斜受け面部３２に固定部材１の取付部１１を当接させて、取付部１１の貫通孔１１ａから傾斜受け面部３２にビス１５を螺入し、右下突出部３１ａに取付部１１を取付ける。また、固定部材１の固定部１３の貫通孔１３ａから根太２にビス１４を螺入して、固定部材１を根太２上に固定する。これにより、右下突出部３１ａは固定部材１を介して根太２に固定されて、板材３を根太２に固定することができる。固定手順としては、本手順に限定されるものではなく、例えば、固定部１３を根太２上に固定した後に、取付部１１を板材３の右下突出部３１ａに取付けてもよい。 The mounting portion 11 of the fixing member 1 is brought into contact with the inclined receiving surface portion 32 of the lower right protruding portion 31a, and the screw 15 is screwed into the inclined receiving surface portion 32 from the through hole 11a of the mounting portion 11 to the lower right protruding portion 31a. Attach the mounting portion 11. Further, the screw 14 is screwed into the joist 2 from the through hole 13a of the fixing portion 13 of the fixing member 1 to fix the fixing member 1 on the joist 2. As a result, the lower right protruding portion 31a is fixed to the joist 2 via the fixing member 1, and the plate material 3 can be fixed to the joist 2. The fixing procedure is not limited to this procedure. For example, after fixing the fixing portion 13 on the joist 2, the mounting portion 11 may be attached to the lower right protruding portion 31a of the plate material 3.

続いて、板材３の反対側の左下突出部３１ｂを根太２に固定する。固定手順は、上記に示した板材３の右下突出部３１ａを固定した手順と同様であって、左下突出部３１ｂを固定する点が異なるのみであるため、既に説明した内容と同じ構成要素には同じ符号を付し、その説明は省略する。なお、本形態では、固定部材１を用いて左下突出部３１ｂを根太２に固定しているが、左下突出部３１ｂ側に隣合う板材３がないことから、左下突出部３１ｂを根太２に固定できるものであればよく、例えば、固定部材１の代わりに、取付部１１と固定部１３とに相当する部位を備えた部材を用いてもよい。 Subsequently, the lower left protruding portion 31b on the opposite side of the plate member 3 is fixed to the joist 2. The fixing procedure is the same as the procedure for fixing the lower right protruding portion 31a of the plate material 3 shown above, except that the lower left protruding portion 31b is fixed, so that the components are the same as those already described. Have the same reference numerals, and the description thereof will be omitted. In this embodiment, the lower left protruding portion 31b is fixed to the joist 2 by using the fixing member 1, but since there is no plate material 3 adjacent to the lower left protruding portion 31b side, the lower left protruding portion 31b is fixed to the joist 2. Anything that can be done may be used, and for example, instead of the fixing member 1, a member having a portion corresponding to the mounting portion 11 and the fixing portion 13 may be used.

図４は、根太に固定された板材の右隣に別の板材の固定構造を示す説明図である。根太２に既に固定した板材３の右側に次の板材３を固定するものであって、その手順は、まず、次の板材３の左下突出部３１ｂを、根太２に既に固定された固定部材１の係止部１２と根太２の上面との間の収納空間４の奥まで挿入し、傾斜受け面部３２が係止部１２に当接し、左下突出部３１ｂの下面側が根太２の上面に当接した状態とする。続いて、次の板材３において、別の固定部材１によって反対側の右下突出部３１ａを根太２に固定する。固定手順は、既に固定した板材３の右下突出部３１ａを根太２に固定した手順と同様であるので、既に説明した内容と同じ構成要素には同じ符号を付し、その説明は省略する。 FIG. 4 is an explanatory view showing a fixing structure of another plate material to the right of the plate material fixed to the joist. The next plate material 3 is fixed to the right side of the plate material 3 already fixed to the joist 2, and the procedure is first to fix the lower left protruding portion 31b of the next plate material 3 to the fixing member 1 already fixed to the joist 2. Is inserted all the way into the storage space 4 between the locking portion 12 and the upper surface of the joist 2, the inclined receiving surface portion 32 abuts on the locking portion 12, and the lower surface side of the lower left protruding portion 31b abuts on the upper surface of the joist 2. It is in the state of being. Subsequently, in the next plate material 3, the lower right protruding portion 31a on the opposite side is fixed to the joist 2 by another fixing member 1. Since the fixing procedure is the same as the procedure for fixing the lower right protruding portion 31a of the plate material 3 that has already been fixed to the joist 2, the same components as those already described are designated by the same reference numerals, and the description thereof will be omitted.

これにより、左右方向に隣合わせて板材３を根太２に固定することができる。すなわち、右隣りの板材３は、左下突出部３１ｂを収納空間４の奥まで挿入するだけでよく、例えば、左下突出部３１ｂを固定するためにビス１４を増し締めしたり、あるいは、ビス１４を一端緩めた後再び増し締めしたりして、根太２と固定部材１との間に左下突出部３１ｂを挟み込むような作業は必要ない。従って、既に固定された固定部材１はそのままでよいので、既に取り付けた板材３の固定状態が緩んだりするような不具合は生じにくい。 As a result, the plate members 3 can be fixed to the joists 2 adjacent to each other in the left-right direction. That is, the plate material 3 adjacent to the right only needs to insert the lower left protruding portion 31b to the depth of the storage space 4. For example, the screw 14 may be retightened to fix the lower left protruding portion 31b, or the screw 14 may be tightened. It is not necessary to loosen it once and then retighten it to sandwich the lower left protrusion 31b between the joist 2 and the fixing member 1. Therefore, since the fixing member 1 already fixed can be left as it is, it is unlikely that the fixed state of the already attached plate material 3 will be loosened.

図５は、図４に示された次の板材３の右隣に更に別の板材３を固定する固定構造を示す説明図である。固定方法は上述と同様であるので詳しい説明は省略するが、このように同様な操作を繰り返すことにより、多数の板材３を根太２に隣合わせて固定することができる。 FIG. 5 is an explanatory view showing a fixing structure for fixing another plate member 3 to the right side of the next plate member 3 shown in FIG. Since the fixing method is the same as described above, detailed description thereof will be omitted, but by repeating the same operation in this way, a large number of plate members 3 can be fixed next to the joists 2.

次に、根太２に固定された板材３を取外すための取り外し方法について、図６〜図１０に基づき詳しく説明する。図６〜図１０において、便宜上、三個の板材３は左から、板材３ａ、板材３ｂ、板材３ｃと表記し、三個のうち中央に位置する板材３ｂを取り外す場合について説明する。 Next, a removal method for removing the plate material 3 fixed to the joist 2 will be described in detail with reference to FIGS. 6 to 10. In FIGS. 6 to 10, for convenience, the three plate materials 3 are referred to as plate material 3a, plate material 3b, and plate material 3c from the left, and a case where the plate material 3b located at the center of the three plates is removed will be described.

図７は、図６における固定部材付近の説明図、図８は図６において取り外されている板材と固定部材との関係を示す説明図である。すなわち、取り外される板材３ｂにおいて、図７は右側端部付近を示しており、図８は左側端部付近を示している。まず、板材３ｂの右下突出部３１ａ側の固定部材１において、ビス１４を根太２から外す。ここで、固定部材１の係止部１２の下側面部１６は、板材３ｃの左下突出部３１ｂとの間に隙間を有している。これにより、板材３ｂの右側をＹ方向である上方に僅かに持ち上げた際、当接していた係止部１２と左下突出部３１ｂの傾斜受け面部３２との間に隙間Ｓ１が生じ、かつ、下側面部１６と左下突出部３１ｂの突出先端部３３との間にも隙間Ｓ２が生じる。 FIG. 7 is an explanatory view of the vicinity of the fixing member in FIG. 6, and FIG. 8 is an explanatory view showing the relationship between the plate material removed in FIG. 6 and the fixing member. That is, in the plate material 3b to be removed, FIG. 7 shows the vicinity of the right end portion, and FIG. 8 shows the vicinity of the left end portion. First, in the fixing member 1 on the lower right protruding portion 31a side of the plate material 3b, the screw 14 is removed from the joist 2. Here, the lower side surface portion 16 of the locking portion 12 of the fixing member 1 has a gap between the lower left side surface portion 16 of the plate member 3c and the lower left protruding portion 31b. As a result, when the right side of the plate member 3b is slightly lifted upward in the Y direction, a gap S1 is generated between the locking portion 12 that has been in contact with the plate member 3b and the inclined receiving surface portion 32 of the lower left protruding portion 31b, and the lower side. A gap S2 is also formed between the side surface portion 16 and the protruding tip portion 33 of the lower left protruding portion 31b.

続いて、板材３ｂと一緒に固定部材１をＸ方向である板材３ｂ側に移動させると、板材３ｂの左下突出部３１ｂは、挿入されていた収納空間４から僅かに引き抜かれて係止状態が緩むので、固定部材１の係止部１２と傾斜受け面部３２との間に生じる隙間Ｓ５に応じて更に板材３ｂの右側をＹ方向に持ち上げることができる。この作業を繰り返して、図９に示すように、板材３ｂの左下突出部３１ｂを収納空間４から完全に抜き出した後、板材３ｂの左側を上方に持ち上げて、図１０に示すように、板材３ｂを上方に抜き出すことができる。 Subsequently, when the fixing member 1 is moved to the plate material 3b side in the X direction together with the plate material 3b, the lower left protruding portion 31b of the plate material 3b is slightly pulled out from the inserted storage space 4 and is locked. Since it loosens, the right side of the plate member 3b can be further lifted in the Y direction according to the gap S5 generated between the locking portion 12 of the fixing member 1 and the inclined receiving surface portion 32. By repeating this operation, as shown in FIG. 9, the lower left protruding portion 31b of the plate material 3b is completely pulled out from the storage space 4, and then the left side of the plate material 3b is lifted upward, and as shown in FIG. 10, the plate material 3b Can be pulled out upwards.

これにより、設置後に破損したり、変形したりして交換が必要となった特定の板材３ｂのみを取り出すことができる。この際、両隣の板材３ａ、板材３ｃは、固定部材１を介して根太２に固定されており、位置ずれが生じにくい状態を維持できる。また、前述の板材３ｂの取り外し操作と逆の手順によって、取り外した箇所に新しい板材３と固定することができる。 As a result, only the specific plate material 3b that is damaged or deformed after installation and needs to be replaced can be taken out. At this time, the plate materials 3a and the plate materials 3c on both sides are fixed to the joists 2 via the fixing member 1, and it is possible to maintain a state in which misalignment is unlikely to occur. Further, the new plate material 3 can be fixed to the removed portion by the reverse procedure of the above-mentioned removal operation of the plate material 3b.

また、図７に示すように、固定部材１の係止部１２の下側面部１６は、本形態では、下方に向かうほど固定部１３の中央側へ切り欠かれた切欠部１７を有しており、板材３ｃの左下突出部３１ｂの突出先端部３３に対して、平面視において、下方に向かうほど左右方向の離間寸法が大きくなっている。これにより、板材３ｂの右側を持ち上げた際、下側面部１６と突出先端部３３との間に比較的大きな隙間が生じやすくなるため、板材３ｂをＸ方向に動かし易くなって、取り外しやすくなる。 Further, as shown in FIG. 7, the lower side surface portion 16 of the locking portion 12 of the fixing member 1 has a notch portion 17 notched toward the center side of the fixing portion 13 toward the lower side in the present embodiment. The distance between the plate member 3c and the protruding tip portion 33 of the lower left protruding portion 31b in the left-right direction becomes larger as it goes downward in a plan view. As a result, when the right side of the plate material 3b is lifted, a relatively large gap is likely to be generated between the lower side surface portion 16 and the protruding tip portion 33, so that the plate material 3b can be easily moved in the X direction and can be easily removed.

更に、板材３ｂの右側を持ち上げる際、板材３ｂの左下突出部３１ｂが収納空間４内で係止されていることから、固定部材１のビス１４を外したのみでは板材３ｂは容易に外れず、板材３ｂ及び固定部材１の少なくとも一方の一部を弾性的に変形させないと板材３ｂの右側を持ち上げることができない形態が好ましい。 Further, when the right side of the plate material 3b is lifted, the lower left protruding portion 31b of the plate material 3b is locked in the storage space 4, so that the plate material 3b cannot be easily removed only by removing the screw 14 of the fixing member 1. It is preferable that the right side of the plate member 3b cannot be lifted unless at least one part of the plate member 3b and the fixing member 1 is elastically deformed.

例えば、本形態のように、板材３ｂの左下突出部３１ｂが、突出先端部３３付近を支点として、傾斜受け面部３２と左右方向に延びる下面部３４とからなる断面く字状となるように形成して、上下方向に弾性変形しやすい構造としてもよく、板材３ｂに下方に向けて開口する中空部３５を設けて、板材３ｂの中央付近が上方に向けて撓み易い構造としてもよい。 For example, as in the present embodiment, the lower left protruding portion 31b of the plate material 3b is formed so as to have a doglegged cross section including an inclined receiving surface portion 32 and a lower surface portion 34 extending in the left-right direction with the vicinity of the protruding tip portion 33 as a fulcrum. Therefore, a structure that is easily elastically deformed in the vertical direction may be provided, or a hollow portion 35 that opens downward in the plate material 3b may be provided so that the vicinity of the center of the plate material 3b is easily bent upward.

図７、図８に示すように、板材３ｂの左下突出部３１ｂを収納空間４の奥まで挿入した時の挿入寸法Ｓ３は、固定部材１の係止部１２の先端部から板材３ｂの左下突出部３１ｂの基端部までの距離Ｓ４より短いことが好ましい。これにより、図９に示すように、左下突出部３１ｂを収納空間４から完全に抜き出した状態においても、板材３ｂの右下突出部３１ａに取付けられた固定部材１の係止部１２を板材３ｃの左下突出部３１ｂの上方に配置することができるので、板材３ｂを取り外し易くなる。 As shown in FIGS. 7 and 8, the insertion dimension S3 when the lower left protruding portion 31b of the plate material 3b is inserted to the depth of the storage space 4 is the lower left protruding portion of the plate material 3b from the tip end portion of the locking portion 12 of the fixing member 1. It is preferable that the distance to the base end portion of the portion 31b is shorter than the distance S4. As a result, as shown in FIG. 9, even when the lower left protruding portion 31b is completely pulled out from the storage space 4, the locking portion 12 of the fixing member 1 attached to the lower right protruding portion 31a of the plate material 3b is locked to the plate material 3c. Since it can be arranged above the lower left protruding portion 31b of the above, the plate material 3b can be easily removed.

板材３は、本形態では、図９に示すように、側端部において、下突出部３１と上下方向に間隔をあけて側方に向けて形成された上突出部３６と、下突出部３１と上突出部３６とを両側壁部として側方に開口する開口部３７とを備えている。これにより、板材３上からは、固定部材１の取付部１１とビス１５、係止部１２が見えにくくなる。なお、板材３を取り外す際、開口部３７内の空間は固定部材１の係止部１２が配置できる大きさであることが好ましい。 In the present embodiment, as shown in FIG. 9, the plate material 3 has an upper protruding portion 36 and a lower protruding portion 31 formed at the side end portions toward the side with a vertical distance from the lower protruding portion 31. It is provided with an opening 37 that opens laterally with the upper protruding portion 36 as both side wall portions. As a result, the mounting portion 11, the screw 15, and the locking portion 12 of the fixing member 1 are difficult to see from above the plate material 3. When removing the plate member 3, the space inside the opening 37 is preferably large enough to accommodate the locking portion 12 of the fixing member 1.

板材３は、本形態では、長尺であって、図１１に示すように、金属製で内部に長手方向に沿って中空状となされた中空部３５を有する芯材３８と、板材３の利用者等が通行する通行面に当たる芯材の上面部に設けられた合成樹脂製の被覆部３９とを備えている。 In the present embodiment, the plate material 3 is a long core material 38 having a hollow portion 35 made of metal and hollow in the longitudinal direction as shown in FIG. 11, and the plate material 3 is used. It is provided with a synthetic resin covering portion 39 provided on an upper surface portion of a core material that corresponds to a passage surface through which a person or the like passes.

芯材３８は、本形態では、薄肉の中空状であって、その中空部３５は、縦壁部によって左右方向に複数に分割されており、下方に向けて一部開口している。本形態においては、左右に４個の中空部を有しており、いずれの中空部も長手方向に切り欠かれて下向きに開口したものであるが、例えば、図１２に示すように、側端部側の中空部３５において、下面部が開口しないようにしてもよい。これにより、板材３の側端部付近の強度を高めることができる。芯材３８は、本形態に限定されるものではなく、板材３を根太２に固定した後、利用者等が板材３上を通行しても容易に変形しないものであることが好ましい。 In this embodiment, the core material 38 has a thin hollow shape, and the hollow portion 35 is divided into a plurality of parts in the left-right direction by a vertical wall portion, and is partially opened downward. In this embodiment, there are four hollow portions on the left and right, and each hollow portion is cut out in the longitudinal direction and opens downward. For example, as shown in FIG. 12, the side end In the hollow portion 35 on the portion side, the lower surface portion may not be opened. Thereby, the strength in the vicinity of the side end portion of the plate material 3 can be increased. The core material 38 is not limited to this embodiment, and it is preferable that the core material 38 is not easily deformed even if a user or the like passes over the plate material 3 after fixing the plate material 3 to the joist 2.

また、芯材３８の上面部及びその両端部から両側面部の上部にわたって被覆部３９が設けられている。被覆部３９が設けられた上面部及び両側の上側面部には、それぞれ長手方向に沿って連続して蟻溝状の溝部３８ａが設けられており、その溝部３８ａ内に被覆部３９の合成樹脂の一部が充填されている。この構造により、被覆部３９は芯材３８に対してアンカー効果が生じるため、芯材３８に対して左右方向及び上下方向には容易には外れない構造となる。
芯材３８の材質は、金属製のものが好ましく、中でも軽量で、比較的強度が高いアルミニウム合金製型材が好適に用いられる。 Further, a covering portion 39 is provided from the upper surface portion of the core material 38 and both end portions thereof to the upper portions of both side surface portions. A dovetail groove-shaped groove 38a is continuously provided along the longitudinal direction on the upper surface portion provided with the covering portion 39 and the upper side surface portions on both sides, and the synthetic resin of the covering portion 39 is provided in the groove portion 38a. Is partially filled. With this structure, the covering portion 39 has an anchor effect on the core material 38, so that the covering portion 39 does not easily come off from the core material 38 in the left-right direction and the up-down direction.
The core material 38 is preferably made of metal, and among them, an aluminum alloy mold material which is lightweight and has relatively high strength is preferably used.

被覆部３９は、本形態では、芯材３８の長手方向に対して押出被覆されたものであり、これにより、被覆部３９を形成する合成樹脂を溝部３８ａ内に容易に充填できるので好ましいが、他の形態として、被覆部３９のみを成型して、その後、芯材３８に取付ける形態でもよく、要は、板材３において、芯材３８から被覆部３９が容易に外れない構造であればよく、例えば、芯材３８と被覆部３９との間に接着層を設けた形態でもよい。 In this embodiment, the covering portion 39 is extruded and coated with respect to the longitudinal direction of the core material 38, which is preferable because the synthetic resin forming the covering portion 39 can be easily filled in the groove portion 38a. As another form, only the covering portion 39 may be molded and then attached to the core material 38. In short, the plate material 3 may have a structure in which the covering portion 39 does not easily come off from the core material 38. For example, an adhesive layer may be provided between the core material 38 and the covering portion 39.

固定部材１は、金属製のものが好ましく、中でも軽量で、比較的強度が高いアルミニウム合金製型材が好適に用いられる。また、固定部材１は、板材３の長手方向に沿って取付けられるものであって、本形態では、板材３より短いものであり、例えば、一個の板材３に複数取付けることにより、根太２に板材３をしっかり固定できるものであるが、例えば、板材３の長さと合わせた形態でもよく、板材３の長手方向に沿って連続的に取付けた形態でもよい。このような形態合であっても、前述と同様に特定の板材３ｂを取り外し、その後、新しい板材３を取り付けることができる。 The fixing member 1 is preferably made of metal, and among them, an aluminum alloy mold material which is lightweight and has relatively high strength is preferably used. Further, the fixing member 1 is attached along the longitudinal direction of the plate material 3, and is shorter than the plate material 3 in this embodiment. For example, by attaching a plurality of fixing members 1 to one plate material 3, the plate material is attached to the joist 2. Although 3 can be firmly fixed, for example, it may be in a form that matches the length of the plate material 3 or may be continuously attached along the longitudinal direction of the plate material 3. Even in such a form, the specific plate material 3b can be removed and then a new plate material 3 can be attached in the same manner as described above.
