【発明の属する技術分野】
本発明は、天井面から滴下する漏水から特に水を嫌う電子計算機、電子顕微鏡等の電子機器類や材料を保護するために、天井下に設けられる漏水防護設備に関する。
【0002】
【従来の技術】
従来より、コンクリート建築物等では施工不良または老朽化等に伴い、躯体のクラックを通って下層階へ雨水等が漏水することがある。特に下層階が電子計算機や精密機械等の設備が設置される電算機室等である場合には、漏水によってこれらの機械設備が侵され甚大な被害を被ることがあった。
【0003】
近年、このような問題に対処するために、天井から防水板を吊り下げ漏水を電子機器類等に滴下させないようにする設備が提案されている。たとえば、特公平6−96880号公報(第1公知例)では、天井の下側に端縁を梁に近接した状態で防水板を配置し、前記梁の下端縁に沿って梁用樋を設けるとともに、この梁用樋の端縁位置より下方に巻装配置される回り樋を設け、前記防水板から流下する漏水を前記梁用樋を介して回り樋に集水する漏水回収装置が開示されている。
【0004】
また、特開昭53−41017号および実開昭52−28914号公報(第2公知例)では、天井面にアンカーボルトを介して取り付けられた下地部材に対して防水板を固定配置する二重天井構造が開示されている。
【0005】
さらに、特開昭53−41017号公報(第3公知例)では、天井側にアーチ状の天井部材を配置するとともに、隣接するアーチ状天井部材の側縁同士に跨って収集溝部材を配設した設備が開示されている。
【0006】
【発明が解決しようとする課題】
しかしながら、前記第1〜第3公知例に係る防水設備では、施工上並びに構造上、種々の問題の発生が予想される。
【0007】
先ず第1公知例の場合は、梁を除く天井面のほぼ全面に防水板を配設しなければならないと同時に、これらの防水板全体を完全に水漏れしない構造としなければならない。実際には梁間の天井面全体を一枚の防水板で覆うことは困難であるから、要所に防水板の接続部が設けられることになるが、この接続部位での水密構造が複雑になる、施工性が悪化するなどの問題が発生する。また、保守管理用に防水板の一部を開閉蓋としたい場合にも全く同様の問題が発生するとともに、接続部位に漏水が発生した場合に室内側からでは補修が困難であるなどの問題もある。さらに、通常のオフィスビル等では天井面に管理用開閉蓋、火災報知器、空調用吹出し口などの設備が設けられていることが多いが、第1公知例の構造ではこれらの設備に対して柔軟に対処し得ないなどの問題もある。
【0008】
次いで、第2公知例は、換言すれば接続部位からの漏水を完全に遮断した防水板支持構造を開示するものであるが、構造が複雑で施工性が悪いとともに、火災報知器、空調用吹出し口などの設備が設けられている既存天井に対する対処が困難である、さらに漏水した水の処理については何ら開示がなく、場合によっては漏水した水が防水板の裏側に滞留したままとなることも予想される。
【0009】
第3公知例は、湿気を発する調理場、洗い場などの極めて狭い部屋に対して適用されるものであり、広い空間を有するオフィスビルなどに対する適用は不向きである。具体的には、第1公知例と同様の問題が発生することになる。
【0010】
そこで本発明の主たる課題は、第1に構造が簡易でかつ隣接する防水板間からの水漏れの心配のない構造にするとともに、防水板の設置が迅速に行え施工性に優れたものとすること、第2に水処理の手法が明確でしかも確実に排水処理し得るものとすること、さらに第3にメンテナンスが容易に行えるとともに、空調用吹出し、火災報知器、照明などの天井設備に対しても容易に対処し得るようにすること、将来の機器の配置変更に対しても柔軟に対応し得るようにすること等にある。
【0011】
【課題を解決するための手段】
前記課題を解決するために請求項1に係る本発明として、室内のほぼ全域または一部において、天井面の下側に、一方側方向に配置される実質的に長手通しの断面U字状の親フレームと、前記親フレーム間に横架される断面U字状の子フレームとから構成されるとともに、前記親フレームの子フレーム連結箇所に、子フレーム端部が嵌合する切欠き部を設けておき、子フレームの両端部にそれぞれ少なくとも底板、両側壁から一体的に略直交方向に延在された係合フランジを備え、前記親フレームに形成された切欠き部に前記係合フランジを嵌合係合させることにより格子状に組まれた樋兼用骨組部材を水平若しくは若干傾斜させて設け、この樋兼用骨組部材の任意の格子枠に対し、周縁部に板本体より一体的に連設された垂下片を備えるとともに、透光性を有する樹脂板またはガラス板からなる防水板を、前記垂下片を格子枠の全周に亘り前記断面U字状部材の格子枠がわ側壁に被せるように載置したことを特徴とする天井漏水からの防護設備が提供される。
【0012】
【発明の実施の形態】
以下、本発明の実施の形態について図面に基づいて詳述する。
【0013】
図1は本発明が適用された室内の平面図、図2は構造概略斜視図、図3は図1のIII−III線矢視図、図4は図1のIV−IV線矢視図である。
【0014】
本漏水防護設備は、天井下の空間部、具体的には天井面と電子機器等との間の空間部分に、所定の離間をおいて一定方向に配置される樋兼用親フレーム2、2…(以下、単に親フレームという。)と、これら親フレーム2、2…の間に横架される樋兼用子フレーム3、3…(以下、単に子フレームという。)とによって構成された格子状の骨組部材1A,1Bを設置し、この骨組み部材1A,1Bの任意の格子枠に対して着脱自在に防水板4、4…を設置した構造である。天井面との間に所定の離間を空けることにより、空気循環を妨げることがなく、火災時の煙感知や空調効率の低下などを防止できるようになる。
【0015】
前記骨組部材1A,1Bは、室内のほぼ全域に配置することも可能であるし、或いは電子機器の設置対象エリア等の特定エリアのみを対象として部分的に配置することも可能である。そして、防水板4、4…についても、骨組部材1A,1Bの全部或いは一部に対して設置することも可能である。図示の例では、室内L側においては、入口部近傍を除く室内のほぼ全域に骨組部材1Aを配置し、相対的に左側のエリアAのみに防水板4、4…を設置し、他方、室内R側においては、室内の一部に骨組部材1Bを設置し、相対的に下側エリアCのみに防水板4、4…を設置してある。将来の機器配置の変更を見越して計画するならば、ある程度広いエリアに亘って骨組部材1A,1Bを配置しておき、防水板4、4…の移設によって容易に対処し得るようにするのがより好適な態様となる。
【0016】
以下、詳細にその構造について施工手順を交えながら詳述すると、
ビル建築等の天井構造は、図2に示されるように、躯体スラブ(図示せず)から吊下された吊りボルト14に対して先ず野縁受け12、12…が支持され、これら野縁受け12、12に適所が固定された野縁10、10、11…に対して天井板13が支持される構造が一般的であり、このような天井構造の場合には、前記野縁10、10を支持体として、先ず前記親フレーム2が吊設される。
【0017】
詳細には、図5に示されるように、天井板13に前記野縁10位置の墨出しを行い、野縁10の天井面直下に断面コ字状のピース部材9を固定ビス8によって固定する。一方、前記親フレーム2の長手方向適所に対して、図2にも示されるように、中央部にネジカプラー7aを固設した断面コ字状の吊り金具7を予め溶接等により固定しておき、この吊り金具7のネジカプラー7aに吊りボルト5の下端を螺入するとともに、この吊りボルト5の上端側をピース部材9の下側フランジ9aに形成された通孔に通し、前記下側フランジ9aを跨ぐ両側に夫々ナット6、6を配設して吊りボルト5の上部を固定し吊持する。本例では、前記吊りボルト5による支持の他、図3および図4に示されるように、天井の強度が不足した場合の補強および親フレーム2の撓み防止並びに落下防止のために、親フレーム2の下面側に水平方向にワイヤー30、30…を壁間に張設している。
【0018】
前記親フレーム2の通り芯の調整並びに高さおよび勾配調整は、前記吊りボルト5のネジカプラー7aに対する螺入量およびナット6、6の調整によって行うことができる。前記親フレーム2、2…は、水平配置でもよいが、好ましくは1/50〜1/200程度の排水勾配を持つように設置するとともに、すべての親フレーム2、2…が同一面内に位置するように調整される。
【0019】
なお、前記親フレーム2としては、好ましくは連結部を有しない1本の部材が使用されるが、輸送等の制限から途中に連結部を設ける場合もある。もちろん、この場合には連結部の目地にシールを施し止水を完全なものとする。いずれにしても、前記親フレーム2は、設置状態において実質的に長手通しとして設置される。また、親フレーム2の支持構造は、前記吊りボルト5による支持の他、たとえば吊りワイヤー等によって吊り下げ支持することでもよい。
【0020】
前述要領によって各親フレーム2、2…を天井下に設置したならば、次いで、直交方向に配置される子フレーム3、3…を取り付ける。
【0021】
前記子フレーム3としては、図7に示されるように、その壁高hが親フレーム3の壁高Hよりもの低いものを使用することとし、各親フレーム2、2…の子フレーム3連結位置には予め、子フレーム3の寸法に合った矩形状の切欠き2a,2aを形成し、一方前記子フレーム3の端部には底板、両側壁から一体的に略直交方向に延在される係合フランジ3a〜3cを形成しておき、この子フレーム3の係合フランジ3a〜3cを前記親フレーム2の切欠き2aに落とし込むことにより両者が連結される。その後、各係合フランジ3a〜3cの隅部k,kからの水漏れ防止およびガタ付き防止のために連結部位の外面周囲にシールを施し1本当たりの連結作業を完了する。なお、前記子フレーム3の端部のフランジ形状を、図8に示されるように、底面および両側面の3辺を連続的に囲む係合フランジ3dとすれば、単に子フレーム3を落とし込むだけで前記隅部Kからの水漏れは完全に防止し得るためシールを不要とすることができ施工の簡略化が図れるようになる。
【0022】
かかる要領によって各子フレーム3、3…を取付け、図1に示されるように、格子状の骨組部材1A,1Bを天井下に構築する。なお、前記子フレーム3を親フレーム2に連結した状態では、後述の防水板4がガタ付かないように、子フレーム3の側壁天端レベルと親フレーム2の側壁天端レベルとが同一になるように、換言すれば前記格子状の骨組連結1A,1Bの完成状態において、その上面レベルが略同一面となるようにする。
【0023】
他方、前記親フレーム2、2…の水下側に配置される端部フレーム材16(以下、集水樋フレームという。)については、親フレーム2から流下してくる水を集水し、さらにこれを水下側に流下させるものでなければならないため、図10に示されるように、前記親フレーム2よりも壁高の高い長手通しのものを使用し、かつ集水樋フレーム16の水下側端部に縦樋17を設け、漏水を外部に確実に排出するようになっている。
【0024】
骨組部材1A,1Bの設置が完了したならば、次に任意の格子枠、本例では骨組部材1A側ではエリアA、骨組部材1B側ではエリアCに対して防水板4、4…を設置する。防水板4は、天井面に設置された照明を遮らないように、好ましくは透明樹脂またはガラス等の素材が用いられ、その周縁(四辺)には一体的に延在する垂下片4a,4a…が形成されている。格子枠の対角線部を利用して骨組部材1A,1Bの上側に通し、図9に示されるように、前記垂下片4a,4a…を格子枠の全周に亘り前記親フレーム2、2および子フレーム材3、3の格子枠がわ側壁に被せるように載置する。なお、防水板4、4…を設置した漏水防護設備の完成状態を図6に示す。この場合、各格子枠の寸法は、なるべく同じとしておき、防水板4、4…の寸法種類を極力少なくするのがよい。本例では、図1に示されるように、長さ調整のため、中央部分は正方形状にすべて同一寸法とし、両端または片側端部に寸法の異なる長方形状の防水板4’を設置するようにしている。また、前記防水板4として、透光性を有する素材を用いることにより、防水板を取り外さなくても天井面の漏水個所を下から容易に確認できるようになる。
【0025】
なお、既存天井は重量物を吊持し得るように本来設計されていないため、前記骨組部材1A.1Bとしては、できるだけ軽量の部材を用いるようにするのがよい。具体的には、ステンレスよりなる薄肉のC型鋼などの他、塩化ビニル樹脂などの樹脂材も好適に使用することができる。また、防水板4についても、撓みが生じない範囲で極力薄肉のものを使用するのがよい。
【0026】
本例のような漏水防護設備であれば、構造が非常に簡易で低コストで済む。また、各防水板4、4…も小さな寸法で済み取り扱い性に優れるとともに、しかも置くだけで設置ができるため施工性の点でも非常に優れたものとなる。さらに、各防水板4、4…は接続部を持たない構造であるため将来的にも水漏れの虞が一切ない。加えて、仮に天井面に火災報知器や空調用吹出し口が存在する場合には、これら機器の設置箇所に相当する格子枠部分に防水板4を取付けないで開口のままとしておけば、これらの機器の障害となることもない。メンテナンスに際しても、任意の箇所から防水板4を上方に持ち上げるだけで骨組部材1A,1Bの裏側に入れるため非常に容易に行うことができるなど、従来のものにはない種々の利点を備えたものとなる。
【0027】
かかる漏水防護設備において漏水が発生した場合には、防水板4、4…に滴下した漏水が子フレーム3、3…に流れ落ち、この子フレーム3を伝わって親フレーム2、2…に流下する。そして、親フレーム2、2…に流れた漏水は排水勾配に従って水下側に流れ、水下側最端部の集水樋フレーム16に集水され、最後に縦樋17から外部に排出される。
【0028】
以上、本発明の一形態例として、親フレーム2、2…、子フレーム3、3…および防水板4、4…から構成される漏水防護設備であって、親フレーム2、2…、次いで子フレーム3、3…、最後に防水板4、4…の手順で施工を行う方法について詳述した。本形態例は、特には既に室内に電子機器類が配置されている場合などに好適に採用されるが、他にたとえば、予め工場にて所定の寸法の格子状骨組ユニットを製作し、これを現場に持ち込んで据え付けるようにしてもよい。各格子状骨組ユニット相互間を簡単に接続できるようにしておけば、大寸法の格子状骨組であっても現場で容易に構築することができる。工場製作される骨組部材の場合には、格子骨組のX方向とY方向の部材を全く同じものとし、すなわち本例のようなそれぞれの方向の部材間で親子の関係を無くし、これらを交点部において溶接により接合するものであってもよい。
【0029】
また、電子機機器類が設置されておらず空室の場合には、床面で地組した後、ワイヤー等で天井側に引き上げそのまま固定するようにしてもよい。
【0030】
【発明の効果】
以上詳説のとおり本発明によれば、基本的に骨組部材と防水板から構成されるものであるため構造が非常に簡易となる。また、各防水板同士は接続部を有しないため従来のような防水板接続部からの水漏れという問題が一切生じない。水板は1枚当たりの重量も軽く取り扱い性に優れ、しかも開口枠部に置くだけでよいため、施工性に優れ短期間で工事を完了し得るようになる。
【0031】
さらに、水処理の手法が明確でしかも確実に排水処理し得るようになるとともに、同時にメンテナンスも容易に行えるようになる。また、空調用吹出し、火災報知器、照明などの天井設備に対しても容易に対処し得るようになり、将来の機器の配置変更に対しても柔軟に対応し得るようになる。

BACKGROUND OF THE INVENTION
The present invention relates to a water leakage protection facility provided under a ceiling in order to protect electronic devices and materials such as an electronic computer and an electron microscope that particularly dislike water from water leaking from a ceiling surface.
[0002]
[Prior art]
Conventionally, rainwater and the like may leak to the lower floor through cracks in a concrete building due to poor construction or aging. In particular, when the lower floor is a computer room or the like in which equipment such as an electronic computer and a precision machine is installed, leakage of water may damage these mechanical equipment and cause serious damage.
[0003]
In recent years, in order to cope with such a problem, a facility has been proposed in which a waterproof plate is suspended from a ceiling so that water leakage does not drop onto electronic devices or the like. For example, in Japanese Examined Patent Publication No. 6-96880 (first known example), a waterproof plate is disposed on the lower side of the ceiling with the end edge close to the beam, and a beam cage is provided along the lower end edge of the beam. In addition, there is disclosed a leakage recovery device that provides a swivel wound around and arranged below the edge position of the beam rod, and collects the water flowing down from the waterproof plate to the swirl via the beam rod. ing.
[0004]
In Japanese Patent Laid-Open No. 53-41017 and Japanese Utility Model Laid-Open No. 52-28914 (second known example), a double-layered structure in which a waterproof plate is fixedly arranged on a base member attached to a ceiling surface via an anchor bolt. A ceiling structure is disclosed.
[0005]
Furthermore, in JP-A-53-41017 (third known example), an arched ceiling member is disposed on the ceiling side, and a collecting groove member is disposed across the side edges of adjacent arched ceiling members. The equipment has been disclosed.
[0006]
[Problems to be solved by the invention]
However, in the waterproof equipment according to the first to third known examples, various problems are expected in terms of construction and structure.
[0007]
First, in the case of the first known example, a waterproof plate must be provided on almost the entire ceiling surface excluding the beam, and at the same time, the entire waterproof plate must have a structure that does not leak completely. In fact, it is difficult to cover the entire ceiling surface between the beams with a single waterproof plate, so a connecting part of the waterproof plate will be provided at the important point, but the watertight structure at this connection site will be complicated Problems such as deterioration of workability occur. In addition, when a part of the waterproof plate is used as an opening / closing lid for maintenance management, the same problem occurs, and when water leaks at the connection site, it is difficult to repair from the indoor side. is there. Furthermore, in ordinary office buildings and the like, facilities such as a management opening / closing lid, a fire alarm, and an air conditioning outlet are often provided on the ceiling surface. There are also problems such as being unable to deal flexibly.
[0008]
Next, the second known example, in other words, discloses a waterproof board support structure that completely blocks water leakage from the connection site. However, the structure is complicated and the workability is poor, and a fire alarm and an air conditioner blowout are disclosed. It is difficult to deal with existing ceilings equipped with facilities such as mouths, and there is no disclosure of treatment of leaked water, and in some cases, leaked water may remain behind the waterproof board. is expected.
[0009]
The third known example is applied to a very narrow room such as a cooking place or a washing place that generates moisture, and is not suitable for an office building having a large space. Specifically, the same problem as in the first known example occurs.
[0010]
Therefore, the main problem of the present invention is that, firstly, the structure is simple and there is no fear of water leakage between adjacent waterproof plates, and the waterproof plate can be installed quickly and has excellent workability. Secondly, the water treatment method must be clear and reliable, and third, maintenance can be easily performed, and air conditioning blowouts, fire alarms, lighting and other ceiling equipment However, it is possible to easily cope with this, and to be able to flexibly cope with future changes in the arrangement of devices.
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, as a first aspect of the present invention, a substantially longitudinal cross-sectional U-shape is arranged in one side direction below the ceiling surface in almost the whole area or a part of the room . The frame is composed of a parent frame and a child frame having a U-shaped cross section that is horizontally mounted between the parent frames, and a notch portion into which a child frame end is fitted is provided at a child frame connecting portion of the parent frame. In addition, at both ends of the child frame, at least a bottom plate and an engagement flange extending integrally from the both side walls in a substantially orthogonal direction are provided, and the engagement flange is fitted into a notch formed in the parent frame. The skeleton and frame members assembled in a lattice shape by being engaged with each other are provided horizontally or slightly inclined, and are connected continuously from the plate body to the peripheral portion of any lattice frame of the skeleton and frame members. was and Ru with a suspended piece Moni, the waterproof plate made of a resin plate or a glass plate having translucency, and the suspended piece is placed so as to cover the U-shaped section lattice frame Kanagawa sidewall member over the entire circumference of the lattice frame Protective equipment against water leakage from the ceiling is provided.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0013]
1 is a plan view of a room to which the present invention is applied, FIG. 2 is a schematic perspective view of the structure, FIG. 3 is a view taken along the line III-III in FIG. 1, and FIG. 4 is a view taken along the line IV-IV in FIG. is there.
[0014]
This water leakage protection system is a combination of the main frame 2, 2 ... which is arranged in a fixed direction at a predetermined distance in a space portion under the ceiling, specifically, a space portion between the ceiling surface and the electronic device. (Hereinafter simply referred to as a parent frame), and a lattice-shaped child frame 3, 3,... (Hereinafter, simply referred to as a child frame) horizontally placed between the parent frames 2, 2,. The frame members 1A, 1B are installed, and waterproof plates 4, 4,... Are detachably installed on arbitrary lattice frames of the frame members 1A, 1B. By providing a predetermined separation from the ceiling surface, air circulation is not hindered, and smoke detection at the time of fire and a decrease in air conditioning efficiency can be prevented.
[0015]
The frame members 1A and 1B can be arranged almost in the whole room, or can be partially arranged only for a specific area such as an installation target area of an electronic device. And it is also possible to install the waterproof plates 4, 4... On all or part of the frame members 1 </ b> A, 1 </ b> B. In the illustrated example, on the indoor L side, the skeleton member 1A is disposed in almost the entire interior of the room except for the vicinity of the entrance, and the waterproof plates 4, 4,. On the R side, the frame member 1B is installed in a part of the room, and the waterproof plates 4, 4... Are installed only in the lower area C. If planning in anticipation of future changes in equipment arrangement, the frame members 1A and 1B are arranged over a relatively wide area so that they can be easily dealt with by moving the waterproof plates 4, 4. It becomes a more suitable aspect.
[0016]
The following is a detailed description of the structure with construction procedures.
As shown in FIG. 2, the ceiling structure of a building or the like is first supported by the field edge receivers 12, 12... With respect to the suspension bolts 14 suspended from the frame slab (not shown). The ceiling plate 13 is generally supported by the field edges 10, 10, 11... Fixed in place at 12, 12. In the case of such a ceiling structure, the field edges 10, 10 are supported. First, the parent frame 2 is suspended.
[0017]
Specifically, as shown in FIG. 5, the position of the field edge 10 is marked on the ceiling board 13, and a piece member 9 having a U-shaped cross section is fixed by a fixing screw 8 immediately below the ceiling surface of the field edge 10. . On the other hand, as shown in FIG. 2, a U-shaped suspension bracket 7 having a screw coupler 7a fixed at the center is fixed to the appropriate position in the longitudinal direction of the parent frame 2 by welding or the like in advance. The lower end of the suspension bolt 5 is screwed into the screw coupler 7a of the suspension fitting 7, and the upper end side of the suspension bolt 5 is passed through the through hole formed in the lower flange 9a of the piece member 9, so that the lower flange Nuts 6 and 6 are disposed on both sides across 9a to fix and suspend the upper part of the suspension bolt 5. In this example, in addition to the support by the suspension bolt 5, as shown in FIGS. 3 and 4, the parent frame 2 is used for reinforcement when the strength of the ceiling is insufficient, prevention of bending of the parent frame 2, and prevention of dropping. Wires 30, 30... Are stretched between the walls in the horizontal direction on the lower surface side.
[0018]
The adjustment of the core of the parent frame 2 and the height and gradient can be adjusted by adjusting the amount of screwing of the suspension bolt 5 into the screw coupler 7a and the nuts 6 and 6. The parent frames 2, 2... May be arranged horizontally, but preferably installed so as to have a drainage gradient of about 1/50 to 1/200, and all the parent frames 2, 2. To be adjusted.
[0019]
The parent frame 2 is preferably a single member that does not have a connecting portion. However, a connecting portion may be provided on the way due to restrictions such as transportation. Of course, in this case, a seal is applied to the joint of the connecting portion to complete the water stop. In any case, the parent frame 2 is installed substantially longitudinally in the installed state. Further, the support structure of the parent frame 2 may be supported by being suspended by a suspension wire, for example, in addition to the support by the suspension bolt 5.
[0020]
If each parent frame 2, 2 ... is installed under the ceiling according to the above-mentioned procedure, then, the child frames 3, 3 ... arranged in the orthogonal direction are attached.
[0021]
As the child frame 3, as shown in FIG. 7, the wall height h is lower than the wall height H of the parent frame 3, and the child frame 3 connection position of each parent frame 2, 2,. The rectangular cutouts 2a and 2a that match the dimensions of the child frame 3 are formed in advance, while the end of the child frame 3 is integrally extended from the bottom plate and both side walls in a substantially orthogonal direction. Engagement flanges 3 a to 3 c are formed, and the engagement flanges 3 a to 3 c of the child frame 3 are dropped into the notch 2 a of the parent frame 2 to connect them. Thereafter, in order to prevent water leakage from the corners k, k of the engaging flanges 3a to 3c and to prevent rattling, a seal is applied around the outer surface of the connecting portion to complete the connecting operation per piece. If the flange shape at the end of the child frame 3 is an engagement flange 3d that continuously surrounds the bottom and both sides as shown in FIG. 8, the child frame 3 can be simply dropped. Since water leakage from the corner K can be completely prevented, a seal is unnecessary, and the construction can be simplified.
[0022]
The child frames 3, 3,... Are attached by such a procedure, and as shown in FIG. 1, lattice-like frame members 1A, 1B are constructed under the ceiling. In the state where the child frame 3 is connected to the parent frame 2, the side wall top end level of the child frame 3 and the side wall top end level of the parent frame 2 are the same so that the later-described waterproof plate 4 is not rattled. In other words, in the completed state of the lattice-like frame connections 1A and 1B, the upper surface level is made to be substantially the same surface.
[0023]
On the other hand, for the end frame member 16 (hereinafter referred to as a catchment frame) disposed on the water side of the parent frames 2, 2,..., The water flowing down from the parent frame 2 is collected, Since this must flow down to the lower side of the water, as shown in FIG. 10, the one having a longitudinal wall with a wall height higher than that of the parent frame 2 is used and the water collecting frame 16 is under the water. A vertical gutter 17 is provided at the side end to reliably discharge the water leak to the outside.
[0024]
When the installation of the frame members 1A and 1B is completed, the waterproof plates 4, 4... Are then installed on an arbitrary lattice frame, in this example, the area A on the frame member 1A side and the area C on the frame member 1B side. . The waterproof plate 4 is preferably made of a material such as transparent resin or glass so as not to block the illumination installed on the ceiling surface, and the hanging pieces 4a, 4a,. Is formed. Using the diagonal part of the lattice frame, it passes through the upper side of the frame members 1A, 1B, and as shown in FIG. 9, the hanging pieces 4a, 4a,. It mounts so that the lattice frame of the frame materials 3 and 3 may cover the side wall. FIG. 6 shows a completed state of the water leakage protection equipment provided with the waterproof plates 4, 4. In this case, it is preferable that the dimensions of the respective lattice frames be the same as much as possible, and the size types of the waterproof plates 4, 4. In this example, as shown in FIG. 1, in order to adjust the length, the central part has a square shape with all the same dimensions, and rectangular waterproof boards 4 ′ having different dimensions are installed at both ends or one end. ing. In addition, by using a light-transmitting material as the waterproof plate 4, it is possible to easily confirm the water leakage location on the ceiling surface from below without removing the waterproof plate.
[0025]
Since the existing ceiling is not originally designed to be able to suspend heavy objects, the frame member 1A. As 1B, it is preferable to use a member as light as possible. Specifically, in addition to thin C-shaped steel made of stainless steel, resin materials such as vinyl chloride resin can also be suitably used. Also, the waterproof plate 4 should be as thin as possible within a range in which bending does not occur.
[0026]
In the case of the water leakage protection equipment as in this example, the structure is very simple and low cost. In addition, each waterproof plate 4, 4... Has a small size and is excellent in handleability and can be installed simply by placing it, so that it is very excellent in terms of workability. Furthermore, since each waterproof board 4,4 ... is a structure which does not have a connection part, there is no possibility of a water leak in the future. In addition, if there are fire alarms and air-conditioning outlets on the ceiling surface, if the waterproof plate 4 is not attached to the lattice frame portion corresponding to the installation location of these devices and they are left open, There is no obstacle to the equipment. For maintenance, it can be very easily done by simply lifting the waterproof plate 4 upward from any point and putting it on the back side of the frame members 1A, 1B. It becomes.
[0027]
When water leakage occurs in such a water leakage protection facility, the water leaked onto the waterproof plates 4, 4... Flows down into the child frames 3, 3, and then flows down to the parent frames 2, 2. Then, the water leaked to the parent frames 2, 2, flows to the lower side according to the drainage gradient, is collected in the water collecting frame 16 at the lowermost end of the water, and is finally discharged from the vertical rod 17 to the outside. .
[0028]
As described above, according to an embodiment of the present invention, there is provided a water leakage protection facility including the parent frames 2, 2,..., The child frames 3, 3,. The method of carrying out the construction in the order of the frames 3, 3... And finally the waterproof plates 4, 4. This embodiment is suitably used especially when electronic devices are already arranged in the room.In addition, for example, a lattice frame unit having a predetermined size is manufactured in advance at a factory, and this is used. It may be brought on site and installed. If each lattice-like frame unit can be easily connected to each other, even a large-sized lattice-like frame can be easily constructed on site. In the case of a frame member manufactured in a factory, the members in the X direction and the Y direction of the lattice frame are exactly the same, that is, there is no parent-child relationship between the members in each direction as in this example, and these are the intersection points. May be joined by welding.
[0029]
In the case where the electronic equipment is not installed and the room is vacant, it may be grounded on the floor and then pulled up to the ceiling side with a wire or the like and fixed as it is.
[0030]
【The invention's effect】
As described above in detail, according to the present invention, the structure is basically simple because it is composed of a frame member and a waterproof plate. Moreover, since each waterproof board does not have a connection part, the problem of the water leakage from a waterproof board connection part like the past does not arise at all. Since each water plate is light in weight and excellent in handleability and only needs to be placed on the opening frame, it is excellent in workability and can be completed in a short period of time.
[0031]
Furthermore, the water treatment method is clear and the wastewater treatment can be surely performed, and at the same time, the maintenance can be easily performed. Moreover, it becomes possible to easily cope with ceiling facilities such as air-conditioning outlets, fire alarms, and lighting, and can flexibly cope with future change of equipment arrangement.
