Description

本考案は、フリーアクセスフロアを構築するフロアパネルに係り、特に、フリーアクセスフロアによって上下に仕切られる床下と床上(室内)との間で空気を流通させるための多数の長孔、所謂通気孔を備えているフロアパネルに関する。   The present invention relates to a floor panel for constructing a free access floor, and in particular, has a number of long holes, so-called ventilation holes, for allowing air to flow between the floor below and above the floor (indoors) partitioned by the free access floor. It relates to the floor panel that is provided.

データセンタ、サーバルーム、コンピュータルーム、そしてクリーンルームなどの大規模な室内では、サーバ機器、OA機器などの各種の設置機器類から発生する熱、そして埃などに対する室内空調(冷却)や防塵(清浄度維持)のために、空気流通用の多数の通気孔を備えているフロアパネル(一般に、「グレーチングパネル、空調用パネル」と称されている)をフロア構築高さ(フロア面)に敷き詰めてフリーアクセスフロア(二重床構造)を構築する床下空調方式が採用されている。   In large-scale rooms such as data centers, server rooms, computer rooms, and clean rooms, indoor air conditioning (cooling) and dust prevention (cleanliness) against heat generated from various types of installation equipment such as server equipment and OA equipment, and dust Maintenance), a floor panel (generally referred to as a “grating panel or air conditioning panel”) with a large number of ventilation holes for air circulation is spread over the floor construction height (floor surface). An underfloor air-conditioning system that constructs an access floor (double floor structure) is adopted.

このようなフリーアクセスフロアは、例えば、コンクリート製の基礎床面(スラブ)に支持脚などと称されている支持部材を、平面視で方形状を呈するフロアパネルの外周枠部の各辺寸法間隔をおいて立設配置し、各支持部材の上に隣接敷き詰められる各フロアパネルの四隅コーナーを載承支持させる施工によって、基礎床面から支持部材の高さに相当する高さをおいて構築される。
これにより、フリーアクセスフロアによって仕切られた床下側(スラブ側)を空調機から空調空気(圧送空気、主に冷気)を供給する空気の供給路(床下チャンバ)とし、この供給路を通して空調機から送り込まれてくる空調空気が、各フロアパネルの通気孔より設置機器類が設置されている床上の室内に吹き出して室内の空調(冷却)や防塵(清浄度維持)を行う床下空調方式としている。
Such a free-access floor is, for example, a support member called a support leg or the like on a concrete base floor (slab), and each side dimension interval of the outer peripheral frame portion of the floor panel that has a square shape in plan view. It is constructed with a height corresponding to the height of the support member from the foundation floor surface by construction that places and supports the four corners of each floor panel that is laid adjacently on each support member. The
As a result, the underfloor side (slab side) partitioned by the free access floor is used as an air supply path (underfloor chamber) for supplying conditioned air (pressurized air, mainly cold air) from the air conditioner, and from the air conditioner through this supply path The conditioned air that is sent in is blown into the room on the floor where the installed devices are installed through the vents of each floor panel, and the room is under-floor air conditioning that performs air conditioning (cooling) and dust prevention (maintenance of cleanliness).

そして、このような床下空調方式のフリーアクセスフロアを構築するために用いられるフロアパネルとしては、例えば、特許文献1などにおいて知られている。   And as a floor panel used in order to construct | assemble such an underfloor air-conditioning-type free access floor, it is known in patent document 1, etc., for example.

ところで、近年では、空調空気の供給路として利用される床下空間を、2000〜3000mmというかなりの高さで確保するために、当該高さレベルでフリーアクセスフロアを構築することが行われるようになってきている。
例えば、数台から数十台のサーバ機器を使用する各企業では、近年、社内でサーバ機器の設置管理を行わずに、外部に委託する傾向が見られる。それは、サーバ機器を設置するための広い部屋(フロア)の確保と室内の空調管理などにコストが掛かるなどからである。
そこで、各企業では、大規模なサーバルームやデータセンタなどを所有し、サーバ機器などの設置管理を専門に取り扱う管理会社にサーバ機器などの設置を委託している。
By the way, in recent years, in order to secure an underfloor space used as a supply path for conditioned air at a considerable height of 2000 to 3000 mm, a free access floor has been constructed at the height level. It is coming.
For example, in recent years, companies that use several to several tens of server devices tend to outsource without installing and managing server devices in-house. This is because it takes costs to secure a large room (floor) for installing the server equipment and to manage the air conditioning in the room.
Therefore, each company has a large-scale server room, data center, etc., and entrusts the installation of server equipment to a management company that specializes in installation management of server equipment.

そして、各企業から設置委託されたサーバ機器などが設置される大規模なサーバルームやデータセンタは、数多くのサーバ機器などから発生する大容量の発熱量に対して、大容量の冷気を2000〜3000mmという高さの床下空間から吹出し循環させることで、大規模なサーバルームやデータセンタの空調(冷却)や防塵(清浄度維持)に対応するものである。
このように、空調機から空調空気(冷気)を供給する空気の供給路となり、また、サーバ機器などからの配線のための空間となる床下空間を、2000〜3000mmの高さを有する広い空間とすることで、配線などで混雑していた状況が解消されて通気性が格段に向上して空調効率が大幅にアップ、そして大容量の冷気の吹出し循環を可能にする。
A large-scale server room or data center in which server equipment commissioned by each company is installed installs a large volume of cool air against the large amount of heat generated from a large number of server equipment. By blowing out and circulating from the underfloor space as high as 3000 mm, it is compatible with air conditioning (cooling) and dustproof (maintenance of cleanliness) in large-scale server rooms and data centers.
In this way, an underfloor space that serves as an air supply path for supplying conditioned air (cold air) from the air conditioner and serves as a space for wiring from a server device or the like is a wide space having a height of 2000 to 3000 mm. As a result, the situation that was congested by wiring etc. is eliminated, the air permeability is remarkably improved, the air conditioning efficiency is greatly improved, and a large volume of cool air can be blown out and circulated.

特開2008−285850号公報JP 2008-285850 A

しかしながら、特許文献1に記載のフロアパネルを含めて従来から知られているフロアパネルは、床下空間を300〜500mm程度の高さにて確保すべくそのフロア構築高さでフロア一面にフリーアクセスフロアを構築することを目的に設計・開発が成されて製作されたもので、2000〜3000mmというフロア構築高さ(高所)においてフリーアクセスフロアを構築することについては全く想定も考慮も成されていない。
そのために、例えば、大規模のサーバルームやデータセンタなどにサーバ機器の設置管理を委託している各企業のサーバ管理者などが、サーバルームやデータセンタに出入りして自社所有のサーバ機器などのメンテナンスや新たなサーバ機器などの増設などを行う場合、サーバルームへの出入り口からサーバ機器の設置場所へ移動する際にフロアに敷設されているフロアパネルの通気孔を通して2000〜3000mmという高さの床下空間がサーバ管理者などの視線(目線)に入り易く、高所恐怖感を与えるおそれがあった。
However, conventionally known floor panels including the floor panel described in Patent Document 1 are free access floors on the entire floor with the floor construction height so as to secure an underfloor space at a height of about 300 to 500 mm. It was designed and developed for the purpose of constructing a building, and it was totally assumed and considered about building a free access floor at a floor construction height (high place) of 2000 to 3000 mm. Absent.
For this purpose, for example, a server administrator of each company entrusted with the installation management of server equipment to a large server room or data center, etc. enters and exits the server room or data center to When performing maintenance, adding new server equipment, etc., the floor below 2000-3000 mm through the vents of the floor panel laid on the floor when moving from the entrance to the server room to the installation location of the server equipment The space easily enters the line of sight (line of sight) of the server administrator or the like, and there is a risk of fear of height.

そこで、本考案は、前記課題を解消するために創案されたものであり、2000〜3000mmという高所にフリーアクセスフロアを構築するフロアパネルであって、通気孔である長孔を通しての床下空間の存在を各企業のサーバ管理者の視線から遮断し得るように、長孔の開口長さ方向の向きやその開口配置などを考慮して新たに設計・開発されたフロアパネルを提供することにある。   Therefore, the present invention was created to solve the above-mentioned problems, and is a floor panel for constructing a free access floor at a high place of 2000 to 3000 mm, and the underfloor space through a long hole that is a vent hole. The purpose is to provide a floor panel that is newly designed and developed in consideration of the direction of the opening length of the long holes and the arrangement of the openings so that the existence can be blocked from the line of sight of the server administrator of each company. .

前記課題を解決するために、本考案では、多数の長孔を備えてフリーアクセスフロアを構築するフロアパネルであって、
方形状を呈する外周枠部の内側領域に、前記長孔を開口長さ方向の向きを複数方向に変えてそれぞれ備えてなり、前記長孔は、前記外周枠部の四辺縁のうち、一辺縁を基準とし、当該一辺縁に対して平行に開口する平行長孔と、前記一辺縁に対して垂直に開口する垂直長孔と、前記一辺縁に対して斜めに開口する斜め長孔とからなり、前記平行長孔、前記垂直長孔、前記斜め長孔は、それぞれが個々に群れを成すように等間隔をおいて、かつ、所定大きさの区画要素内に並列開口されて、前記四辺縁側からそれぞれ見たときに、それぞれの開口長さ方向の開口縁が開口向き方向の違いにより交わる如く見えるように前記外周枠部の内側領域に配置されることを特徴とする。
In order to solve the above problems, the present invention is a floor panel having a large number of long holes to construct a free access floor,
In the inner region of the outer peripheral frame portion having a square shape, the long holes are respectively provided by changing the direction of the opening length direction to a plurality of directions, and the long holes are one side edge among the four side edges of the outer peripheral frame portion. And a parallel long hole that opens parallel to the one edge, a vertical long hole that opens perpendicular to the one edge, and an oblique long hole that opens obliquely to the one edge. The parallel elongated holes, the vertical elongated holes, and the oblique elongated holes are equally spaced so as to form a group individually, and are opened in parallel in a partition element of a predetermined size, When viewed from above, the opening edges in the respective opening length directions are arranged in the inner region of the outer peripheral frame portion so as to appear to intersect due to the difference in opening direction.

ここで、前記斜め長孔は、対称形にて傾斜方向の向きを変えた二種類からなること、そして、前記平行長孔、前記垂直長孔、前記斜め長孔は、裏面に向けて突出するリブを開口縁に沿わせてそれぞれ備え、該リブが、断面視で略斜め下向き形状または略L字形状に形成されていること、さらに、前記平行長孔、前記垂直長孔、前記斜め長孔は、前記外周枠部の内側領域の中心点に対して点対称にそれぞれ開口配置されていること、などの構成を採用することが好適なものとなる。   Here, the oblique long hole is formed of two types which are symmetrical and the direction of the inclination direction is changed, and the parallel long hole, the vertical long hole and the oblique long hole protrude toward the back surface. Ribs are provided along the opening edges, respectively, and the ribs are formed in a substantially obliquely downward shape or a substantially L-shape in a sectional view, and further, the parallel elongated holes, the vertical elongated holes, and the oblique elongated holes It is preferable to adopt a configuration such that the openings are arranged point-symmetrically with respect to the center point of the inner region of the outer peripheral frame portion.

本考案のフロアパネルによれば、外周枠部の四辺縁のうち、一辺縁を基準とする平行長孔、垂直長孔、斜め長孔は、外周枠部の内側領域に配置されるそれぞれの区画要素内で個々に群れを成すように等間隔をおいて並列開口されて、四辺縁側(四方)から見たときに、それぞれの開口長さ方向の開口縁が開口向き方向の違いにより交わる如く見えるように外周枠部の内側領域に配置されていることで、例えば、サーバルームなどにおいて、各企業などのサーバ管理者がサーバルームに出入りしたとき、サーバ管理者の視線には平行長孔、垂直長孔、斜め長孔からなる長孔の開口長さ方向の開口縁が交わる如く見える。
つまり、フロアパネルの開口している多数の長孔は、孔ではなく、線や面としてサーバ管理者の視線に入る錯覚をサーバ管理者などに与えることができる。これにより、2000〜3000mmという高さの床下空間の存在を各企業のサーバ管理者の視線から遮断する効果が得られる。
According to the floor panel of the present invention, among the four edges of the outer peripheral frame portion, the parallel long hole, the vertical long hole, and the oblique long hole with respect to one edge are the respective sections arranged in the inner region of the outer peripheral frame portion. Opened in parallel at equal intervals so as to form groups in the element, when viewed from the four side edges (four sides), the opening edges in the opening length direction appear to intersect due to the difference in opening direction. Thus, for example, in a server room, when a server administrator of each company enters or exits the server room, the server administrator's line of sight has a parallel long hole, It looks like the opening edges in the opening length direction of the long holes composed of long holes and oblique long holes intersect.
That is, a large number of long holes opened in the floor panel can give the server administrator the illusion of entering the line of sight of the server administrator as a line or surface instead of a hole. Thereby, the effect which interrupts | blocks the presence of the underfloor space of 2000-3000 mm from the server administrator's eyes | visual_axis of each company is acquired.

また、斜め長孔を一方向のみならず、対称形にて向きを変えた二種類とすること、そして、長孔の開口長さ方向の開口縁に沿って設けられるリブの断面形状を、略斜め下向き形状または略L字形状とすること、などの構成を採用することで、遮断効果をより一層効果的に向上させることができる。   In addition, the oblique elongated holes are not limited to one direction, but two types of directions that are changed symmetrically, and the cross-sectional shape of the rib provided along the opening edge in the opening length direction of the elongated holes is approximately By adopting a configuration such as an obliquely downward shape or a substantially L shape, the blocking effect can be further effectively improved.

また、平行長孔、垂直長孔、斜め長孔の外周枠部の内側領域への配置を、内側領域の中心点に対して点対称としていることで、フリーアクセスフロアを施工する際のフロアパネルの敷設作業時において、フロアパネルの敷設方向性を気にすることなく、フロアパネルをフロア構築高さ(フロア面)に敷き詰め配設することができる。   In addition, the arrangement of the parallel long holes, vertical long holes, and slanted long holes in the inner area of the outer peripheral frame is point-symmetric with respect to the center point of the inner area, so that the floor panel when constructing the free access floor During the laying work, the floor panel can be laid and arranged at the floor construction height (floor surface) without worrying about the direction of laying the floor panel.

<< Description of partition elements >>
FIG. 3 is a schematic plan view of the floor panel according to the present embodiment showing an example of the arrangement of the partition elements in the inner region. Here, description will be made with reference to FIGS. 1 and 2 as appropriate.
As shown in FIG. 1, the partition elements S <b> 1 to S <b> 9 are formed in the inner region of the outer peripheral frame portion 2 by the outer peripheral frame portion 2, the large rib 3, and the middle rib 4, respectively, in a rectangular shape, a quadrangular shape, and a triangular shape in plan view. Thus, the parallel long hole 1a, the vertical long hole 1b, and the two slanted long holes 1c and 1d are areas for opening in parallel at equal intervals so as to form groups respectively.

すなわち、大リブ3は、図1および図2に示すように、外周枠部2から所定の間隔をおいてその内側に平行に四辺縁2a〜2d間にわたりそれぞれ突出配置されている。
また、大リブ3は、内側領域の中心点Pを通ってフロアパネルAの四隅コーナーの交差連設部6間にわたる対角線上Xに位置してそれぞれ突出配置されている。
That is, as shown in FIGS. 1 and 2, the large rib 3 is disposed so as to protrude from the outer peripheral frame portion 2 across the four edges 2 a to 2 d in parallel to the inside at a predetermined interval.
Further, the large ribs 3 are respectively disposed so as to protrude on the diagonal line X extending between the cross connection portions 6 at the four corners of the floor panel A through the center point P of the inner region.
