Description

本発明は、フロアパネル及びその製造方法に関するものである。   The present invention relates to a floor panel and a manufacturing method thereof.

事務所及びオフィスなどに使用されるフロアは、図５に示すように建物の床下地８０に立設した支持脚８５上に床材となるフロアパネル９０を敷設し、床下地８０とフロアパネル９０との間に空間９５を形成し、前記床下空間９５を電源及び電子機器用の配線空間として利用する二重床施工が行われている。このフロアパネル９０はその４隅を支持脚８５により支持され、フロアパネル９０上には事務机、書棚及び電子機器などが配置される。   As shown in FIG. 5, a floor used in an office or an office has a floor panel 90 as a floor material laid on a support leg 85 erected on the floor base 80 of the building. A double-floor construction is performed in which a space 95 is formed between the two and the underfloor space 95 is used as a wiring space for a power source and an electronic device. The floor panel 90 is supported at its four corners by support legs 85, and an office desk, a book shelf, an electronic device, and the like are arranged on the floor panel 90.

特許文献１に示されるフロアパネルは、コンピュータ室等の高床として充分な強度を備えるため４辺の周囲と対向する辺に渡された鉄筋と、エキスパンドメタルにより補強された構造となっている（図６を参照）。
特許文献２に示されるフロアパネルは、強度および製造性を高めると共に薄型化や軽量化を図ることを目的として、鉄筋等のバー材と金属製のメッシュ材とを一体化させパネル内に埋め込んだコンクリート製のフロアパネルが記載されている（図７を参照）。 The floor panel disclosed in Patent Document 1 has a structure reinforced with expanded steel and reinforcing bars passed to the sides facing the periphery of the four sides in order to have sufficient strength as a high floor such as a computer room (see FIG. 1). 6).
The floor panel shown in Patent Document 2 is embedded in a panel by integrating a bar material such as a reinforcing bar and a metal mesh material for the purpose of improving strength and manufacturability and reducing the thickness and weight. A concrete floor panel is described (see FIG. 7).

特開昭６０−１６８８６２号公報JP 60-168862 A 特開２００４−３０８２８４号公報JP 2004-308284 A

しかしながら、特許文献１に示されたフロアパネルの構造では、対向する辺に渡された鉄筋は夫々１本ずつであり、高荷重がフロアパネル中央部に印加された場合には撓み量が大きくなり、フロアパネルを厚くしなければ対応することができなかった。また、フロアパネルを厚くした場合には、電源及び電子機器用の配線空間として利用される床下空間が狭くなり、配線作業などがやり難くなる問題がある。
また、特許文献２に示されたフロアパネルの構造では、４辺の周囲と対向する辺に渡された鉄筋等のバー材と金属製のメッシュ材とを溶接等により一体化させフロアパネル内に埋め込んだ構造としており、製造上の負荷及び製造コストがかかる問題がある。 However, in the structure of the floor panel shown in Patent Document 1, there is one reinforcing bar passed to each of the opposing sides, and the amount of deflection increases when a high load is applied to the center of the floor panel. It was not possible to cope with this problem unless the floor panel was thickened. In addition, when the floor panel is thickened, there is a problem that the underfloor space used as the wiring space for the power supply and the electronic device is narrowed, making it difficult to perform wiring work.
Further, in the structure of the floor panel disclosed in Patent Document 2, a bar material such as a reinforcing bar and a metal mesh material, which are passed to the sides facing the periphery of the four sides, are integrated by welding or the like in the floor panel. Since the structure is embedded, there is a problem that a manufacturing load and a manufacturing cost are required.

本発明の実施形態を図面に基づいて説明する。
図１は、本発明に係るフロアパネルの内部構造を示す説明図である。
長方形状のコンクリート製フロアパネル１０は、そのコンクリート内部に補強バー材１９，２０と補強用メッシュ４０を埋設している。
そして、補強バー材は、外側補強バー材１９と内側補強バー材２０とからなっている。
外側補強バー材１９は、フロアパネル１０の４辺に配置されるものであり、内側補強バー材２０は、対向する辺の略中央部に渡されて縦横十字に交差するように配置されるものである。
なお、補強メッシュ４０は、これら配筋された補強バー材１９，２０とフロアパネル面１１との間に配置されている。 Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory diagram showing the internal structure of a floor panel according to the present invention.
The rectangular concrete floor panel 10 has reinforcing bar members 19 and 20 and a reinforcing mesh 40 embedded therein.
The reinforcing bar material includes an outer reinforcing bar material 19 and an inner reinforcing bar material 20.
The outer reinforcing bar material 19 is disposed on the four sides of the floor panel 10, and the inner reinforcing bar material 20 is disposed so as to cross the vertical and horizontal crosses across the substantially central part of the opposite side. It is.
The reinforcing mesh 40 is disposed between the reinforcing bar members 19 and 20 and the floor panel surface 11 that are arranged.

上記内側補強バー材２０は、フロアパネル１０の対向する辺の略中央部を渡してそれぞれ４本ずつ配置され、その両端部２１に設けられた保持具３０によってフロアパネル面１１と略平行に所定の間隔を設けて保持される。
図２は、内側補強バー材２０を保持している保持具３０の縦断面図である。保持具３０は、基体３１上に内側補強バー材２０を所定の間隔で握持するように保持する保持部３２を連接して設けることで、４本の内側補強バー材２０を所定の間隔でフロアパネル面１１と略平行に保持している。このように、フロアパネル１０の中央部を縦断又は横断する４本の内側補強バー材２０をフロアパネル面１１と略平行に所定の間隔で保持させることにより、４本の内側補強バー材２０それぞれにコンクリートが行き渡り、内側補強バー材２０とコンクリートとの付着性を高めると共に、フロアパネル中央部での撓み量を小さくして強度を向上させることができる。また、４本の内側補強バー材２０がフロアパネル面１１と略平行に保持されているため、フロアパネル１０を厚くすることなく強度を向上させることができる。 The four inner reinforcing bar members 20 are arranged so as to cross the substantially central portions of the opposite sides of the floor panel 10, and each of the inner reinforcing bar members 20 is predetermined substantially parallel to the floor panel surface 11 by the holders 30 provided at both ends 21 thereof. Is held at an interval of.
FIG. 2 is a vertical cross-sectional view of the holder 30 holding the inner reinforcing bar member 20. The holding tool 30 is provided with a holding portion 32 that holds the inner reinforcing bar member 20 on the base 31 so as to hold the inner reinforcing bar member 20 at a predetermined interval, thereby connecting the four inner reinforcing bar members 20 at a predetermined interval. It is held substantially parallel to the floor panel surface 11. In this way, the four inner reinforcing bar members 20 are respectively held at predetermined intervals substantially parallel to the floor panel surface 11 so that the four inner reinforcing bar members 20 that vertically cut or cross the center portion of the floor panel 10 are respectively retained. The concrete can be spread over to improve the adhesion between the inner reinforcing bar member 20 and the concrete, and the amount of bending at the center of the floor panel can be reduced to improve the strength. In addition, since the four inner reinforcing bar members 20 are held substantially parallel to the floor panel surface 11, the strength can be improved without increasing the thickness of the floor panel 10.

以下に示す表１は、本発明に係るフロアパネルの性能を示す表である。
フロアパネルをφ８０鋼製支持台で４点支持し、φ５０荷重子を用いてオートグラフ（荷重試験機）にて荷重し、最大荷重（破壊荷重）及び荷重時のたわみ量を測定した。
これによれば、本発明に係るフロアパネルは、パネル中央及びパネル辺中央ともに、最大荷重が規格値よりも遙かに優れている。また、たわみ量は、５０００Ｎ負荷時において、３０００Ｎ負荷時の規格値を満たしている。これにより、従来の規格を軽くクリアする程の強度を有することが証明された。従って、フロアパネルの厚みを薄くして、強度を保ちながら軽量化を図ることも可能となる。

Figure 0004989997
Table 1 shown below is a table showing the performance of the floor panel according to the present invention.
The floor panel was supported at four points on a φ80 steel support, loaded with an autograph (load tester) using a φ50 loader, and the maximum load (destructive load) and the amount of deflection at the time of loading were measured.
According to this, in the floor panel according to the present invention, the maximum load is far superior to the standard value in both the panel center and the panel side center. Further, the deflection amount satisfies the standard value at the time of 3000N load at the time of 5000N load. As a result, it has been proved that it has a strength enough to lightly clear the conventional standard. Therefore, it is possible to reduce the thickness of the floor panel and reduce the weight while maintaining the strength.
