Description

本発明は、床面に敷設されるフロアパネル材に関する。 The present invention relates to a floor panel material laid on a floor surface.

オフィスビル等の建物において、コンクリートスラブ等からなる床面上にフロアパネル材を敷設して、床面とフロアパネル材との間に空間を形成し、この空間に電源ケーブルや通信ケーブル等を配線することが行われている。このようなフロアパネル材は、床面上に立設される複数の脚部と、これら脚部の上部に設けられて床面に沿う天板部とを有する構造のものが一般的である（例えば、特許文献１〜３参照）。フロアパネル材は、上側に載置される机やキャビネット等の什器を支持するため、ある程度の耐荷重性能が必要とされている。 In a building such as an office building, floor panel material is laid on the floor surface made of concrete slab, etc., and a space is formed between the floor surface and floor panel material, and power cables and communication cables are wired in this space. To be done. Such a floor panel material generally has a structure having a plurality of leg portions standing on the floor surface and a top plate portion provided on the upper portion of the leg portions and extending along the floor surface ( For example, see Patent Documents 1 to 3). Since the floor panel material supports furniture such as a desk or cabinet placed on the upper side, a certain load resistance performance is required.

パネル部１１（ａ）〜１１（ｉ）は、それぞれ、図１，図２に示すように略正方形状の天板部２１と、図４，図５に示すように天板部２１の各角部から天板部２１に対し垂直に延出する４カ所の脚部２２とを有しており、すべての天板部２１が基本的に同一平面に配置されるように図１，図２に示す連結部１５によって連結されている。フロアパネル材１は、施工時に、パネル部１１（ａ）〜１１（ｉ）のそれぞれの脚部２２を下側に天板部２１を上側にして床面に敷設されることになるが、その際に床面上に脚部２２が立設される状態になり、天板部２１がこれら脚部２２の上部に設けられて床面に沿うことになる。 The panel portions 11 (a) to 11 (i) respectively have a substantially square top plate portion 21 as shown in FIGS. 1 and 2 and each corner of the top plate portion 21 as shown in FIGS. 4 and 5. 1 and 2 so that all the top plate portions 21 are basically arranged on the same plane. It is connected by the connecting part 15 shown. At the time of construction, the floor panel material 1 is laid on the floor surface with the leg portions 22 of the panel portions 11 (a) to 11 (i) on the lower side and the top plate portion 21 on the upper side. At this time, the leg portions 22 are erected on the floor surface, and the top plate portion 21 is provided above the leg portions 22 and extends along the floor surface.

パネル部１１（ａ）〜１１（ｉ）は、ほぼ同形状であるため、一つのパネル部１１について説明する。図７に示すように、すべての脚部２２は、それぞれが、天板部２１の角部側に配置されて鉛直方向に沿う一対の外側板部２５と、天板部２１の角部とは反対側に配置されて鉛直方向に沿う一対の内側板部２６とからなる四角筒状をなしている。脚部２２は、一方の外側板部２５および一方の内側板部２６が、この脚部２２近傍の角部を構成する天板部２１の一方の外縁部に平行をなし、他方の外側板部２５および他方の内側板部２６が、この脚部２２近傍の角部を構成する天板部２１の他方の外縁部に平行をなしている。 Since the panel parts 11 (a) to 11 (i) have substantially the same shape, only one panel part 11 will be described. As shown in FIG. 7, each of the leg portions 22 is arranged on the corner portion side of the top plate portion 21, and a pair of outer plate portions 25 along the vertical direction, and the corner portions of the top plate portion 21 are It has a rectangular cylindrical shape that is arranged on the opposite side and includes a pair of inner plate portions 26 along the vertical direction.

すべての縁側補強部４５は、図６に示すように、対応する縁側開口部３１の延在方向に沿う両縁部から下方に延出する一対の縁側縦リブ５０と、図４，図７に示すように、これら一対の縁側縦リブ５０の天板部２１とは反対側の端縁部同士を連結する縁側横リブ５１とを有している。一対の縁側縦リブ５０は、全長にわたって天板部２１に連結されており、天板部２１に垂直をなしている。縁側横リブ５１は、全長にわたって一対の縁側縦リブ５０に連結されており、天板部２１と平行をなしている。一対の縁側縦リブ５０およびこれらを連結する縁側横リブ５１は、これらが下側から覆う縁側開口部３１の延在方向両側に配置されている二カ所の脚部２２の対向する内側板部２６同士を連結している。これにより、パネル部１１では、図７に示すように脚部２２と縁側補強部４５とが交互に配置されて四角枠状に連結されている。 As shown in FIG. 6, all the edge side reinforcing portions 45 include a pair of edge side vertical ribs 50 extending downward from both edge portions along the extending direction of the corresponding edge side opening 31, and FIGS. 4 and 7. As shown, the pair of edge-side vertical ribs 50 have edge-side lateral ribs 51 that connect end edges opposite to the top plate part 21. The pair of edge-side vertical ribs 50 are connected to the top plate portion 21 over the entire length, and are perpendicular to the top plate portion 21. The edge side horizontal rib 51 is connected to the pair of edge side vertical ribs 50 over the entire length, and is parallel to the top plate portion 21. The pair of edge-side vertical ribs 50 and the edge-side horizontal ribs 51 that connect them are the inner plate portions 26 that are opposed to the two leg portions 22 that are disposed on both sides in the extending direction of the edge-side opening 31 that covers them from below.
