Description

本発明は、平板形状の上板の周縁部と、この上板に対向する側に凹部を備えた下板の周縁部とを接合固定するとともに、上板に向けて突出する下板の突起の先端と上板とを接合固定した床パネルに関する。 The present invention bonds and fixes the peripheral edge of the flat plate-shaped upper plate and the peripheral edge of the lower plate having a recess on the side facing the upper plate, and the protrusion of the lower plate protruding toward the upper plate. The present invention relates to a floor panel in which a tip and an upper plate are joined and fixed.

近年、事務所の床面に配線用空間を形成するための二重床システムが採用されている。この二重床システムは、コンクリートスラブなどの床基材の上に多数の支持脚を立設して支持脚により床パネルを支持することにより、床パネルと床基材との間の隙間を配線用空間とし、この配線用空間に電力線、情報線等のケーブルを配線するようにしている。 In recent years, a double floor system for forming a wiring space on the floor of an office has been adopted. In this double floor system, a large number of support legs are erected on a floor base material such as concrete slab, and the floor panel is supported by the support legs, thereby wiring a gap between the floor panel and the floor base material. A space such as a power line and an information line is wired in this wiring space.

このような二重床システムに使用する床パネルとしては、平板形状の上板と、この上板側にモルタルなどの充填材を収容する凹部を備える下板とを備え、これら上板及び下板を互いに重ね合わせてその外周縁部を接合固定している。 As a floor panel used in such a double floor system, a flat plate-shaped upper plate and a lower plate provided with a recess for accommodating a filler such as mortar on the upper plate side are provided. Are overlapped with each other and their outer peripheral edge portions are joined and fixed.

また、下板には、上板と反対側を凹ませることで上板に向けて突出する突起を設け、この突起の先端と上板とを接合固定している（下記特許文献１参照）。 Further, the lower plate is provided with a protrusion that protrudes toward the upper plate by denting the side opposite to the upper plate, and the tip of the protrusion and the upper plate are joined and fixed (see Patent Document 1 below).

ところで、このような床パネルは、通常ほぼ正方形状としてあり、これを順次床面に施工配置する際には、そのままの形状で施工スペースの全域を埋め尽くすことができない場合があり、最後に残った例えば壁際の未施工のスペースに合わせるために、床パネルを切断する必要が生じることがある。この際、壁際の未施工スペースの寸法を測った上で、その寸法に合わせて現場にて床パネルを切断することになる。 By the way, such a floor panel is usually formed in a substantially square shape, and when it is sequentially constructed and arranged on the floor surface, the entire construction space may not be filled in as it is, and finally left. For example, the floor panel may need to be cut to fit the unworked space near the wall. At this time, after measuring the dimension of the unconstructed space near the wall, the floor panel is cut at the site according to the dimension.

ここで、床パネルを切断する作業は、平板形状の上板の表面に、上記測定寸法に合わせて切断線を罫書いてから行うが、その際、上板の表面に単に寸法線を罫書いただけであると、切断線を、下板の突起の先端と上板との接合固定位置に罫書いてしまう恐れがあり、接合固定位置に沿って床パネルを切断した場合には、床パネルの強度が低下するものとなる。 Here, the work to cut the floor panel is done after scoring the cutting line on the surface of the flat plate according to the above measurement dimensions, but at that time, you can simply scoring the dimension line on the surface of the top board. If the floor panel is cut along the joint fixing position, the cutting line may be marked at the joint fixing position between the tip of the lower plate protrusion and the upper plate. Decreases.

そこで、本発明は、床パネルを切断する際の強度低下を防止することを目的としている。 Then, this invention aims at preventing the strength fall at the time of cut | disconnecting a floor panel.

請求項１の発明は、平板形状の上板と、この上板に対向する側に凹部を備えた下板とを備え、前記上板の周縁部と前記下板の凹部外側の周縁部とを接合固定するとともに、前記下板は、前記上板と反対側を凹ませることで上板に向けて突出する突起を複数備え、この各突起の先端と前記上板とを接合固定した床パネルであって、前記上板の表面に、前記突起の先端と前記上板との接合固定位置を示す寸法目印を設けたことを特徴とする。 The invention of claim 1 includes a flat plate-shaped upper plate and a lower plate having a recess on the side facing the upper plate, and a peripheral portion of the upper plate and a peripheral portion of the lower plate outside the recess. In addition to bonding and fixing, the lower plate is provided with a plurality of protrusions that protrude toward the upper plate by denting the side opposite to the upper plate, and a floor panel in which the tip of each protrusion and the upper plate are bonded and fixed. In addition, a dimensional mark indicating a joining and fixing position between the tip of the protrusion and the upper plate is provided on the surface of the upper plate.

請求項１の発明によれば、寸法目印に対応する部位については切断しないようにすることで、下板側の突起の先端と上板との接合固定部位の切断による床パネルの強度低下を防止することができる。 According to the first aspect of the present invention, the portion corresponding to the size mark is not cut, thereby preventing the strength of the floor panel from being lowered due to the cutting of the joint fixing portion between the tip of the lower plate-side protrusion and the upper plate. can do.

以下、本発明の実施の形態を図面に基づき説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１に示す床パネル１は、いずれも平面視でほぼ正方形状の上板３及び下板５と、これら上板３及び下板５相互間の空隙に充填される充填材としてのモルタル７とを備えている。上板３及び下板５は、鋼板で構成した金属製であり、下板５は、上板３に対向する側に凹部５ａを備えるとともに、上板３と反対側の裏面には、凹曲面で構成される複数の窪み部となるディンプル５ｂを備えて、プレス成形されている。すなわち、下板５は、上板３と反対側を凹ませることで上板３に向けて突出する突起５ｃを複数備えていることになる。 The floor panel 1 shown in FIG. 1 has an upper plate 3 and a lower plate 5 that are substantially square in plan view, and a mortar 7 as a filling material that fills a gap between the upper plate 3 and the lower plate 5. It has. The upper plate 3 and the lower plate 5 are made of metal made of a steel plate, and the lower plate 5 includes a concave portion 5a on the side facing the upper plate 3 and a concave curved surface on the back surface opposite to the upper plate 3. And dimples 5b to be a plurality of hollow portions constituted by the above. That is, the lower plate 5 includes a plurality of protrusions 5 c that protrude toward the upper plate 3 by denting the side opposite to the upper plate 3.

上記したディンプル５ｂ（突起５ｃ）は、図２に示すように、縦方向及び横方向にいずれも等間隔に複数配列して設けてあり、また配列方向最も外側の端部に位置するディンプル５ｂ（突起５ｃ）と床パネル１の端部との間隔も、ディンプル５ｂ（突起５ｃ）相互の間隔とほぼ同等としている。 As shown in FIG. 2, a plurality of the dimples 5b (projections 5c) are arranged at equal intervals both in the vertical direction and the horizontal direction, and the dimples 5b ( The distance between the protrusion 5c) and the end of the floor panel 1 is also substantially equal to the distance between the dimples 5b (protrusion 5c).

これらの上板３及び下板５は、外周部に形成してある周縁部としてのフランジ部９及び１１を、溶接やヘム曲げなどによって接合固定するとともに、上記した下板５の突起５ｃの先端と上板３との接触部を溶接によって接合固定して溶接固定位置となる突起溶接部１３を形成している。 The upper plate 3 and the lower plate 5 are formed by joining and fixing flange portions 9 and 11 as peripheral portions formed on the outer peripheral portion by welding, hem bending, and the like, and the tips of the protrusions 5c of the lower plate 5 described above. The contact portion between the upper plate 3 and the upper plate 3 is joined and fixed by welding to form a projection welded portion 13 serving as a welding fixing position.

そして、上板３と下板５との間の空隙を構成する凹部５ａ内には、前記した充填材としてのモルタル７を充填している。 And the mortar 7 as an above-mentioned filler is filled in the recessed part 5a which comprises the space | gap between the upper board 3 and the lower board 5. FIG.

このような床パネル１は、図３に示すように、互いに隣接するもの同士の角部周辺を支柱１５により支持して、該支柱１５を設置してあるコンクリートスラブなどの床基材とで二重床システムを構成している。 As shown in FIG. 3, such a floor panel 1 is supported by a floor base material such as a concrete slab on which corners of adjacent ones are supported by a column 15 and the column 15 is installed. Configures a heavy floor system.

ここで、本実施形態では、図１（ａ）に示すように、上板３の表面には、縦方向及び横方向にそれぞれ等間隔に形成してある突起溶接部１３に対応して寸法目印１７を設けている。すなわち、この寸法目印１７は、図１（ａ）中で縦方向に並ぶ複数の突起溶接部１３の配列方向上下両側の端部付近に設けることで、該複数の突起溶接部１３の配列方向の延長線上に位置するとともに、図１（ａ）中で横方向に並ぶ複数の突起溶接部１３の配列方向左右両側の端部付近に設けることで、該複数の突起溶接部１３の配列方向の延長線上に位置している。 Here, in this embodiment, as shown in FIG. 1A, the surface of the upper plate 3 has dimension marks corresponding to the projection welds 13 formed at equal intervals in the vertical and horizontal directions. 17 is provided. That is, the dimension mark 17 is provided in the vicinity of the ends on the upper and lower sides in the arrangement direction of the plurality of projection welds 13 arranged in the vertical direction in FIG. An extension in the arrangement direction of the plurality of projection welds 13 is provided near the ends on both the left and right sides in the arrangement direction of the plurality of projection welds 13 arranged on the extension line and arranged in the lateral direction in FIG. Located on the line.

したがって、突起溶接部１３相互の間隔の寸法をあらかじめ把握しておけば、寸法目印１７の位置を目印として床パネル１を切断することが可能となる。 Therefore, if the dimension of the interval between the projection welds 13 is known in advance, the floor panel 1 can be cut using the position of the dimension mark 17 as a mark.

なお、図１（ａ）に示す突起溶接部１３は、単にその溶接位置を示すものであって、溶接状態を図示するものではなく、したがってこの溶接部位を図のように外部から容易に判別できるものではない。また、寸法目印１７は、刻印や印刷あるいはシールの貼付によって表示することができるが、その表示方法は特に限定されるものではない。 In addition, the projection welding part 13 shown to Fig.1 (a) only shows the welding position, Comprising: A welding state is not illustrated, Therefore, this welding site | part can be easily discriminate | determined from the outside like a figure. It is not a thing. The dimension mark 17 can be displayed by stamping, printing, or sticking a sticker, but the display method is not particularly limited.

このような構造の床パネル１を使用した二重床システムにおいて、床パネル１を室内の床面に支柱１５に支持させながら、順次敷き詰めて施工していく。そして、最後に例えば壁際の未施工の領域が、正方形の床パネル１では狭過ぎる場合には、その未施工の領域に合わせて、床パネル１を切断する。 In the double floor system using the floor panel 1 having such a structure, the floor panel 1 is laid down and constructed in sequence while the floor panel 1 is supported on the indoor floor surface by the support 15. Finally, for example, when the unconstructed area near the wall is too narrow in the square floor panel 1, the floor panel 1 is cut according to the unconstructed area.

その際、本実施形態では、上記未施工の領域の寸法を計測し、この計測した寸法に合わせて床パネル１（上板３）の表面に、例えば図１（ａ）のように切断線１９を罫書き、この切断線１９に沿って切断する（図４参照）。ここで本実施形態では、切断線１９は、突起溶接部１３に対応する寸法目印１７を避けて罫書くものとする。なお、図１（ａ）では２本の切断線１９を罫書き、この２本の切断線１９に沿って切断することで、２枚の切断パネル２１，２３を作製している。 At this time, in this embodiment, the dimension of the unconstructed region is measured, and the cutting line 19 is formed on the surface of the floor panel 1 (upper plate 3) according to the measured dimension, for example, as shown in FIG. Is cut along the cutting line 19 (see FIG. 4). Here, in this embodiment, the cutting line 19 is ruled while avoiding the dimension mark 17 corresponding to the protrusion welded portion 13. In FIG. 1A, two cut lines 19 are produced by scoring two cut lines 19 and cutting along the two cut lines 19.

これにより、上記未施工の領域に合わせて床パネル１を切断する際に、突起溶接部１３を切断してしまうことを避けることができ、この結果突起５ｃの先端と上板３との突起溶接部１３の切断による床パネル１の強度低下を防止することができる。 Thereby, when cutting | disconnecting the floor panel 1 according to the said un-constructed area | region, it can avoid cutting the projection welding part 13, As a result, projection welding of the front-end | tip of the protrusion 5c and the upper board 3 is possible. The strength reduction of the floor panel 1 due to the cutting of the portion 13 can be prevented.

また、切断線１９を罫書き入れる作業は、両端の寸法目印１７を目当てに効率よく行え、作業スピードが速くなって作業性が向上する。なお、この寸法目印１７の間隔は、床パネル１を縦横５００ｍｍの正方形状とした場合に、７１ｍｍ程度となるので、図６に示す床パネル１０のように、切断線２５を縦方向及び横方向に細かく多数設けた場合に比較して寸法把握が容易にできる。図６に示す床パネル１０の場合には、特に作業スピードが要求される現場での寸法把握に時間がかかり、作業効率の低下を招く。 Further, the work of marking the cutting line 19 can be performed efficiently with the dimensional marks 17 at both ends as targets, so that the work speed is increased and the workability is improved. In addition, since the space | interval of this dimension mark 17 will be about 71 mm when the floor panel 1 is made into the square shape of length and width 500 mm, like the floor panel 10 shown in FIG. Compared with the case where a large number are provided finely, the dimensions can be easily grasped. In the case of the floor panel 10 shown in FIG. 6, it takes time to grasp the dimensions in the field where the work speed is particularly required, resulting in a reduction in work efficiency.

図５は、参考例として、上記した突起溶接部１３とは関係なく、縦横５００ｍｍの正方形状の床パネル１Ａの表面に、周囲四辺の端部に沿って１００ｍｍ間隔に寸法目印１７を設けた例を示している。 FIG. 5 shows, as a reference example, an example in which dimension marks 17 are provided at intervals of 100 mm along the edges of the surrounding four sides on the surface of a square floor panel 1A having a length and width of 500 mm irrespective of the above-described protrusion welded portion 13. Is shown.

上記した参考例では、図１に示した本発明の実施形態と同様に、切断線１９を罫書き入れる作業が、１００ｍｍ間隔の寸法目印１７を目当てに効率よく行え、作業スピードが速くなって作業性が向上する。 In the above-described reference example, as in the embodiment of the present invention shown in FIG. 1, the work of marking the cutting line 19 can be efficiently performed with the dimensional mark 17 at 100 mm intervals as the target, and the work speed is increased and the workability is increased. Will improve.
