【発明の詳細な説明】 （産業上の利用分野） 本発明は、OAフロア構築用のプレキャストコンクリート
床板に関するものである。TECHNICAL FIELD The present invention relates to a precast concrete floorboard for constructing an OA floor.
（発明の課題とその特徴点） 最近、OA機器の導入が盛んになり、オフィス内の配線・
配管が問題となるに伴い、床の内部に配線・配管用の空
間を設けたいわゆOAフロアの採用が考えられつつある。(Problems of the invention and their characteristic points) Recently, the introduction of OA equipment has become popular, and
As piping becomes a problem, we are considering using the Waiyu OA floor, which will have a space for wiring and piping inside the floor.
本発明は、前記趨勢に鑑み、OAフロア構築用として好適

ときは、床板の複数枚を横に並べて粱間に架設した後、
その上に、床板の本体上面のリブの項面に底面を合わせ
て適宜厚さの鉄筋コンクリート層を打設する。When building a floor using the precast concrete floorboard for OA floor construction of the present invention (hereinafter, simply referred to as floorboard), after arranging a plurality of floorboards side by side and erection in the pit,
On top of that, a reinforced concrete layer having an appropriate thickness is placed by matching the bottom face with the rib face on the upper face of the floor plate body.
（図面による説明） 図面において、１は床板の本体であり、その上面には長

間隔で接合鉄筋３が上方に突出して埋設されている。(Description by Drawings) In the drawings, reference numeral 1 is a main body of a floor plate, and a plurality of ribs 2 extending in the length direction from a central portion to positions on appropriate inner sides of both ends in a lengthwise direction are provided in a protruding manner, and each rib 2 has Joined reinforcing bars 3 are embedded in the length direction so as to protrude upward at appropriate intervals.
本体１の両端の支承部4,4は、せん断抵抗増強のため
に、中央部よりも肉厚に形成され、また、本体１の長さ
方向には、曲げ抵抗増強のためにプレストレスが導入さ
れている。The support portions 4, 4 at both ends of the main body 1 are formed to be thicker than the central portion in order to increase shear resistance, and prestress is introduced in the longitudinal direction of the main body 1 to increase bending resistance. Has been done.
リブ２の突設とプレストレスの導入とにより、本体１は
比較的肉薄でも床板の曲げ抵抗は十分に大であるが、大
スパンで高荷重の場合は、さらに、第４図に示すよう
に、リブ２の下方に下向きのリブ５を突設するのがよ
い。Due to the protruding ribs 2 and the introduction of prestress, the bending resistance of the floor plate is sufficiently large even if the main body 1 is relatively thin, but in the case of a large span and high load, as shown in FIG. It is preferable to project a downward rib 5 below the rib 2.
前述の床板を用いて床を構築するときは、床板の複数枚

ンクリート層８との合成床を構成する。When building a floor using the above-mentioned floor boards, after arranging multiple floor boards side by side and installing them between the adjacent grits 6 and 6, the adjacent ribs
Forming spaces for forming spaces are installed between the facets of the ribs 2 and 2 and above the bearings 4 and 4, respectively (as shown in FIGS. 3 and 4 around the rib 2 facet). A notch 7 for installing the formwork is provided), a bottom surface of the rib 2 is aligned with the bottom surface, and a reinforced concrete layer 8 is placed. Are joined together,
A composite floor consisting of a floor plate made of precast concrete and a cast-in-place reinforced concrete layer 8 is constructed.

配線・配管を簡単に行うことができる。A space 9 extending in the longitudinal direction (span direction) between the adjacent ribs 2 and 2 in the central portion of the synthetic floor constructed as described above.
Further, since a space 10 extending laterally (in the length direction of the slag) is formed outside the rib 2 in the support portion 4, OA equipments installed on the floor by utilizing these spaces. Wiring and piping can be done easily.
