支持具本体21は、円筒状に形成され、上方が閉塞され且つ下方が開放されている。そして、支持具本体21は、平面状に形成される上面がパネル部11(連結部112)と当接することで、構成材1を支持する。また、支持具本体21は、内周部に、径方向内方に突出し且つ上下方向に延びる突出部211,…を備える。さらに、支持具本体21は、上面部の表側(外側)に、凹部212を備え、それに伴い凸部213が上面部の裏側(内側)に形成されている。   The support tool main body 21 is formed in a cylindrical shape, and is closed at the top and opened at the bottom. And the support tool main body 21 supports the structural material 1 by the upper surface formed in planar shape contact | abutting with the panel part 11 (connection part 112). Moreover, the support tool main body 21 includes projecting portions 211,... Projecting inward in the radial direction and extending in the vertical direction on the inner peripheral portion. Furthermore, the support main body 21 includes a recess 212 on the front side (outside) of the upper surface portion, and accordingly, a projection 213 is formed on the back side (inside) of the upper surface portion.

枢着部22は、弾性部23を介して、支持具本体21に固定される基部221を備える。また、枢着部22は、基部221から上方に向けて突出し、連結部112の取付孔112aに挿入される挿入部222を備える。   The pivot portion 22 includes a base portion 221 that is fixed to the support body 21 via the elastic portion 23. In addition, the pivot portion 22 includes an insertion portion 222 that protrudes upward from the base portion 221 and is inserted into the attachment hole 112 a of the connection portion 112.

基部221は、取付孔112aを係止することで、挿入部222が取付孔112aに所定以上挿入するのを防止すべく、取付孔112aより大きく形成される。また、基部221は、支持具2が付勢されていない状態、即ち、弾性部23が弾性変形していない状態では、支持具本体21の上面よりも下方側に位置している。   The base portion 221 is formed larger than the mounting hole 112a so as to prevent the insertion portion 222 from being inserted into the mounting hole 112a by a predetermined amount or more by locking the mounting hole 112a. Further, the base 221 is positioned below the upper surface of the support tool body 21 in a state where the support tool 2 is not biased, that is, in a state where the elastic part 23 is not elastically deformed.

挿入部222は、取付孔112aに挿入するのを容易にすべく、先端側がテーパ状に形成されると共に、弾性変形するように円筒状に形成される。そして、挿入部222は、取付孔112aに挿入されたのちに取付孔112aから抜け出るのを防止すべく、基端側が段差状に形成される。   The insertion portion 222 is formed in a cylindrical shape so as to be elastically deformed while being formed in a tapered shape in order to facilitate insertion into the mounting hole 112a. The insertion portion 222 is formed in a stepped shape on the base end side so as to prevent the insertion portion 222 from coming out of the attachment hole 112a after being inserted into the attachment hole 112a.

弾性部23は、下方側に湾曲した板状に形成される。そして、弾性部23は、一端部が支持具本体21の上方側に連結され、他端部が枢着部22の基部221に連結される。こにより、弾性部23は、付勢されることにより弾性変形することで、支持具本体21と枢着部22とを上下方向で相対的に変位させることができる。   The elastic part 23 is formed in a plate shape curved downward. The elastic portion 23 has one end connected to the upper side of the support body 21 and the other end connected to the base 221 of the pivoting portion 22. Thereby, the elastic part 23 can be displaced relatively in the up-down direction by elastically deforming by being biased.

以上より、本実施形態に係るフリーアクセスフロア構成材1は、各連結部112が板状部材111a,…の下端部同士を連結するため、パネル部11に上方から荷重が加えられた際に、板状部材111a,…の下端部同士が離反するのを抑制できる。したがって、亀裂や割れが生じるのを抑制できるため、耐荷重性能を向上させることができる。   From the above, the free access floor constituting material 1 according to the present embodiment connects the lower ends of the plate-like members 111a,... To each connecting portion 112, and therefore when a load is applied to the panel portion 11 from above, It can suppress that the lower end parts of plate-shaped member 111a and ... separate. Therefore, since it can suppress that a crack and a crack arise, load bearing performance can be improved.

また、連結部112が設けられることで耐荷重性能が向上するため、例えば、連結部112が設けられていない場合と同じ耐荷重性能を維持するのであれば、板状部材111aの厚みを薄くしたり、板状部材111aの数量を少なくしたりすることもできる。したがって、効率的に設計を行うことにより、フリーアクセスフロア構成材1を製造するための原料使用量を少なくすることも可能である。   Further, since the load bearing performance is improved by providing the connecting portion 112, for example, if the same load bearing performance as that when the connecting portion 112 is not provided is maintained, the thickness of the plate-like member 111a is reduced. Or the number of plate-like members 111a can be reduced. Therefore, by efficiently designing, it is possible to reduce the amount of raw material used for manufacturing the free access floor constituting material 1.

また、本実施形態に係るフリーアクセスフロア構成材1は、複数の支柱部12,…に亘って配置される格子部111に対して、連結部112が支柱部12,…同士を連結するように配置されるため、パネル部11に上方から荷重が加えられた際に、板状部材111a,…の下端部同士が離反するのを抑制できると共に、支柱部12,…同士が離反するのも抑制できる。したがって、耐荷重性能をさらに向上させることができる。   In addition, the free access floor constituting material 1 according to the present embodiment is configured such that the connecting portion 112 connects the strut portions 12 to each other with respect to the lattice portion 111 arranged over the plurality of strut portions 12. Therefore, when a load is applied to the panel portion 11 from above, it is possible to suppress the lower end portions of the plate-like members 111a,. it can. Therefore, the load bearing performance can be further improved.

また、本実施形態に係るフリーアクセスフロアの支持構造は、パネル部11を支持する支持具2がフリーアクセスフロア構成材1に枢着されるため、平面状に形成される連結部112の下面に沿って支持具2を回動することができる。したがって、支持具2がパネル部11(連結部112)の支持する部位を自由に調整できるため、加えられる荷重に応じて、フレキシブルに対応することができる。   Moreover, the support structure of the free access floor according to the present embodiment is such that the support 2 supporting the panel unit 11 is pivotally attached to the free access floor constituting material 1, so The support tool 2 can be rotated along. Therefore, since the site | part which the support tool 2 supports the panel part 11 (connection part 112) can be adjusted freely, according to the load applied, it can respond flexibly.

ここで、並設される構成材1のうち、床の端側に配置される構成材1は、当該床のスペースの関係上、切断される場合がある。そして、構成材1が切断されると、支柱部12,12による支持だけでは十分でない場合が殆どである。そこで、図10(a)に示すように、支持具2,…を回動させることで、耐荷重性能が一番優れる位置に支持具2,…を配置することもできる。   Here, among the components 1 arranged side by side, the components 1 arranged on the end side of the floor may be cut due to the space of the floor. When the component 1 is cut, in most cases, the support by the support columns 12 and 12 is not sufficient. Therefore, as shown in FIG. 10 (a), by rotating the support tools 2,..., The support tools 2,.

また、本実施形態に係るフリーアクセスフロアの支持構造は、取付孔112aを係止する基部221が支持具本体21の上面よりも下方側に位置している。これにより、図10(b)に示すように、基部221が取付孔112aを係止していない状態、即ち、基部221が取付孔112aと離間している状態で、支持具本体21の上面が平面状に形成される連結部112の下面と当接する。   Further, in the support structure for the free access floor according to the present embodiment, the base portion 221 that locks the attachment hole 112 a is located below the upper surface of the support tool main body 21. As a result, as shown in FIG. 10B, the upper surface of the support body 21 can be seen in a state where the base 221 does not lock the mounting hole 112a, that is, in a state where the base 221 is separated from the mounting hole 112a. It contacts the lower surface of the connecting portion 112 formed in a planar shape.

したがって、支持具本体21の上面が連結部112の下面と密接しているため、荷重が加えられた際に、音鳴り(構成材1と支持具2とが衝突して発生する音)が発生しない。但し、例えば、作業ミス等により、挿入部222が取付孔112aに十分に挿入されていない場合には、取付孔112aを係止する基部221が支持具本体21の上面よりも下方に位置しているだけでは、支持具本体21の上面が連結部112の下面と密接しない場合も考えられる。   Therefore, since the upper surface of the support tool main body 21 is in close contact with the lower surface of the connecting portion 112, a sound is generated when the load is applied (sound generated when the component 1 and the support tool 2 collide). do not do. However, for example, when the insertion portion 222 is not sufficiently inserted into the mounting hole 112a due to a work mistake or the like, the base portion 221 that locks the mounting hole 112a is positioned below the upper surface of the support tool body 21. It is also conceivable that the upper surface of the support body 21 is not in intimate contact with the lower surface of the connecting portion 112 simply by being present.

しかしながら、本実施形態に係る支持具2によれば、支持具本体21の下端部が支柱部12の下端部よりも下方側に位置しているため、構成材1及び支持具2が構造床Xの上に設置されると、支持具本体21の下端部が構造床Xに当接する。これにより、構成材1の自重により、弾性部23が付勢されて弾性変形するため、支持具本体21が枢着部22に対して上下方向において接近するように、即ち、支持具本体21が連結部112に対して接近するように変位することになる。   However, according to the support 2 according to the present embodiment, since the lower end of the support main body 21 is located below the lower end of the support column 12, the component 1 and the support 2 are structured floor X. When installed on the top, the lower end of the support body 21 comes into contact with the structural floor X. Thereby, the elastic part 23 is urged and elastically deformed by its own weight, so that the support body 21 approaches the pivoting part 22 in the vertical direction, that is, the support body 21 is It will move so that it may approach with respect to the connection part 112. FIG.

したがって、支持具本体21の上面が平面状に形成される連結部112の下面と密着することができるため、音鳴りが発生しない。以上のように、挿入部222が取付孔112aに十分に挿入されている場合は当然として、作業ミス等により、挿入部222が取付孔112aに十分に挿入されていない場合においても、支持具本体21の上面が平面状に形成される連結部112の下面と密接することができ、その結果、荷重が加えられた際に、音鳴りが発生するのを防止できる。   Therefore, since the upper surface of the support tool main body 21 can be in close contact with the lower surface of the connecting portion 112 formed in a flat shape, no noise is generated. As described above, as a matter of course, when the insertion portion 222 is sufficiently inserted into the attachment hole 112a, even when the insertion portion 222 is not sufficiently inserted into the attachment hole 112a due to a work mistake or the like, the support body The upper surface of 21 can be brought into close contact with the lower surface of the connecting portion 112 formed in a planar shape, and as a result, it is possible to prevent the generation of noise when a load is applied.
