The interval between the mark 26 and the periphery of the waterproof sheet 21 is slightly wider than the interval between the protrusion 71 and the protrusion 72 described later.

本実施の形態におけるシート挟持装置30は、防水シート21の周縁部を前後に挟み込むものであり、開口枠40と、シート押え材50と、連結手段と、第一突条71,72と、第二突条73と、を備える。   The sheet clamping device 30 in the present embodiment sandwiches the peripheral edge of the waterproof sheet 21 in the front-rear direction, and includes an opening frame 40, a sheet pressing member 50, a connecting means, first protrusions 71 and 72, A bifurcated line 73;

本実施の形態において開口枠40は、建造物1の開口部2の少なくとも左右両側部を構成するものであり、当該開口枠40の内側が、出入口や通路とされた開口部2であるとともに、防水シート21を受けるシート受け材として機能するものである。すなわち、開口枠40は、開口部2を構成する枠体と、防水シート21を受けるシート受け材とが一体化されたものである。   In the present embodiment, the opening frame 40 constitutes at least the left and right sides of the opening 2 of the building 1, and the inside of the opening frame 40 is the opening 2 that is an entrance or a passage, It functions as a sheet receiving material that receives the waterproof sheet 21. That is, the opening frame 40 is obtained by integrating a frame body that forms the opening 2 and a sheet receiving material that receives the waterproof sheet 21.

開口枠40は、開口部2の左右両側部を構成する一対の縦枠41,42を有する。これら一対の縦枠41,42は、ステンレスやアルミニウム等の金属を押出成形してなる。ただしこれに限れるものではなく、硬質樹脂を押出成形してなるものでもよい。
なお、開口枠40は、使用用途や使用場所に応じて断面形状を適宜変更してもよい(後述する突条1,72,73を除く)。例えば窓等の開口部を構成するものであれば、建具用のレールが形成されていたり、建造物1の壁に取り付けるための取付部を備えていたりしてもよい。
The opening frame 40 has a pair of vertical frames 41 and 42 that constitute both the left and right sides of the opening 2. The pair of vertical frames 41 and 42 are formed by extruding a metal such as stainless steel or aluminum. However, the present invention is not limited to this, and it may be formed by extruding a hard resin.
In addition, the opening frame 40 may change a cross-sectional shape suitably according to a use application or a use place (except the protrusions 1, 72, and 73 mentioned later). For example, as long as it constitutes an opening such as a window, a rail for joinery may be formed, or an attachment for attaching to the wall of the building 1 may be provided.

また、図2,図3に示す開口枠40は、バリアフリーに対応するために下縁部が無い状態となっている。この場合には、凹部6の立壁面8をシート挟持装置30の一部として機能させる。すなわち、後述するシート押え材50の横押え部53が凹部6の立壁面8に対向する。また、凹部6の立壁面8の前面と開口枠40の縦枠41,42の前面は面一になっている。さらに、これら立壁面8と縦枠41,42は一体的であることが望ましい。つまり、凹部6の立壁面8は、開口部2の下縁部を構成するものでもあり、縦枠41,42と一体的であるとするならば、開口枠40の横枠(下枠)として機能する。
この開口枠40の前面には、後述する第一突条71,72が前方に突出した状態で設けられている。また、凹部6の立壁面8に対しても後述する第一突条71,72が前方に突出して設けられているものとする。これら開口枠40と凹部6における第一突条71,72同士は連続的に設けられているものとする。

Moreover, the opening frame 40 shown in FIGS. 2 and 3 is in a state where there is no lower edge portion in order to cope with barrier-free. In this case, the standing wall surface 8 of the recess 6 is caused to function as a part of the sheet clamping device 30. That is, a lateral pressing portion 53 of a sheet pressing member 50 to be described later faces the standing wall surface 8 of the recess 6. The front surface of the standing wall 8 of the recess 6 and the front surfaces of the vertical frames 41 and 42 of the opening frame 40 are flush with each other. Further, it is desirable that the standing wall surface 8 and the vertical frames 41 and 42 are integrated. That is, the standing wall surface 8 of the recess 6 also constitutes the lower edge of the opening 2, and if it is integrated with the vertical frames 41, 42, as a horizontal frame (lower frame) of the opening frame 40. Function.
On the front surface of the opening frame 40, first protrusions 71 and 72 described later are provided in a state of protruding forward. In addition, it is assumed that first protrusions 71 and 72, which will be described later, are also provided on the standing wall surface 8 of the recess 6 so as to protrude forward. It is assumed that the first protrusions 71 and 72 in the opening frame 40 and the recess 6 are continuously provided.
In view of this, the opening frame 40 has left and right vertical frames 41 and 42 and a lower horizontal frame 43. The vertical frames 41 and 42 extend vertically in parallel with each other, and the horizontal frame 43 extends left and right. The lower ends of the vertical frames 41 and 42 are connected to the left end and the right end of the horizontal frame 43, respectively. Therefore, the vertical frame 41 and the horizontal frame 43 form a right angle 45 therebetween, and the vertical frame 42 and the horizontal frame 43 form a right angle corner 46 therebetween.

開口枠40は、建造物1の所定の位置において開口部2が形成された場所に、開口部2の縁部に沿って設けられている。
縦枠41が開口部2の左縁に沿って設けられ、縦枠42が開口部2の右縁に沿って設けられ、横枠に相当する凹部6の立壁面8が開口部2の下縁を構成するようにして設けられている。
横枠については、開口部2の底面5の屋外側の箇所に凹部6が形成され、その底面5と凹部6の底7とを結ぶ立壁面8が縦枠41,42の前面と面一になっている。なお、凹部6の底7には、一または複数の水抜き穴が設けられている。

シート押え材50は、開口部2の少なくとも左右両側部に沿って設けられ、開口枠40の前に突き合わせられて使用時に連結されるものである。
より具体的に説明すると、本実施の形態におけるシート押え材50は、U字型に一繋がりに設けられたステンレスやアルミニウム等の金属製の角パイプである。
シート押え材50が左右の縦押え部51,52および横押え部53を有し、縦押え部51,52が互いに平行となって上下に延び、横押え部53が左右に延び、縦押え部51,52の下端が横押え部53の左端と右端にそれぞれ連結されている。
したがって、縦押え部51と横押え部53がこれらの間に直角な角部55を形成し、縦押え部52と横押え部53がこれらの間に直角な角部56を形成する。
The sheet pressing member 50 is provided along at least the left and right sides of the opening 2, but is abutted in front of the opening frame 40 and is connected in use.
More specifically, the sheet pressing member 50 in the present embodiment is a metal square pipe such as stainless steel or aluminum provided in a continuous manner in a U shape.
The sheet pressing member 50 has left and right vertical pressing portions 51 and 52 and a horizontal pressing portion 53. The vertical pressing portions 51 and 52 extend vertically in parallel with each other, the horizontal pressing portion 53 extends to the left and right, and the vertical pressing portion. The lower ends of 51 and 52 are connected to the left end and the right end of the lateral presser portion 53, respectively.
Therefore, the vertical pressing portion 51 and the horizontal pressing portion 53 form a right-angled corner portion 55 therebetween, and the vertical pressing portion 52 and the horizontal pressing portion 53 form a right-angled corner portion 56 therebetween.

シート押え材50の後面が開口枠40の前面に突き合わせられ、図示しない連結手段によってシート押え材50が開口枠40に連結されて固定されている。
具体的には、縦押え部51,52の後面が縦枠41,42の前面にそれぞれ突き合わせられ、横押え部53の後面が凹部6の立壁面8に突き合わせられ、これによって防水シートを挟み込み、その状態を維持できるように連結手段によって連結固定されている。
The rear surface of the sheet pressing member 50 is abutted against the front surface of the opening frame 40, and the sheet pressing member 50 is connected to the opening frame 40 and fixed by a connecting means (not shown).
Specifically, the rear surfaces of the vertical pressing portions 51 and 52 are abutted against the front surfaces of the vertical frames 41 and 42, respectively, and the rear surface of the horizontal pressing portion 53 is abutted against the standing wall surface 8 of the recess 6, thereby sandwiching the waterproof sheet, It is connected and fixed by connecting means so that the state can be maintained.

なお、連結手段としては、例えばトグルラッチやパッチン錠等と呼称され、シート押え材50と開口枠40に跨る引き寄せ金具や、シート押え材50の前面側から開口枠40に向かって螺入されるボルト等の締結具、その他の連結具(例えば、クリップ、爪、フック、鋲、ゴム、バネ)が好適に採用される。すなわち、本発明の趣旨を逸脱しない範囲で適宜変更可能である。   For example, the connecting means is called a toggle latch or a patch lock, and is a drawing metal fitting straddling the sheet pressing member 50 and the opening frame 40 or a bolt screwed into the opening frame 40 from the front side of the sheet pressing member 50. Etc., and other connecting tools (for example, clips, claws, hooks, hooks, rubber, springs) are preferably employed. That is, changes can be made as appropriate without departing from the spirit of the present invention.

連結手段による連結は解除可能である。連結手段の連結が解除されると、シート押え材50が開口枠40に対して接離可能となる。具体的には、シート押え材50がその下端を回転軸として前後に傾動可能に設けられ、シート押え材50が傾動動作によって開口枠40に対して前後に接離する。つまり、シート押え材50が前に(屋外側へ)倒伏すると、シート押え材50が開口枠40から離れ、シート押え材50が後ろに(室内側へ)起立すると、シート押え材50が開口枠40に突き合わせられる。ここで、シート押え材50の横押え部53がヒンジ60によって凹部6の底7に連結され、そのヒンジ60の軸が左右に延在する。   The connection by the connecting means can be released. When the connection of the connecting means is released, the sheet pressing member 50 can be brought into and out of contact with the opening frame 40. Specifically, the sheet pressing member 50 is provided so as to be tiltable back and forth with its lower end as a rotation axis, and the sheet pressing member 50 contacts and separates from the opening frame 40 in the front-rear direction by the tilting operation. That is, when the sheet presser material 50 falls forward (to the outdoor side), the sheet presser material 50 moves away from the opening frame 40, and when the sheet presser material 50 stands rearward (to the indoor side), the sheet presser material 50 moves to the opening frame. 40. Here, the lateral pressing portion 53 of the sheet pressing member 50 is connected to the bottom 7 of the recess 6 by the hinge 60, and the axis of the hinge 60 extends to the left and right.

シート押え材50の可動範囲が0°を超え、90°以下に制限されることが好ましい。例えば、シート押え材50が開口枠40に突き当てられた状態から最も前に倒れた状態までの回転角が所定角度(例えば、45°)に制限される。その所定角度が小さいほど、シート押え材50を倒伏・起立させる際のシート押え材50の移動距離を短くすることができる。ただし、その所定角度は、シート押え材50が最も前に倒れた状態において、防水シート21の下縁部を凹部6の立壁面8と横押え部53との間に挿入できる程度の角度とする。   It is preferable that the movable range of the sheet pressing member 50 be limited to more than 0 ° and not more than 90 °. For example, the rotation angle from the state in which the sheet pressing member 50 is abutted against the opening frame 40 to the state in which the sheet pressing member 50 is tilted most forward is limited to a predetermined angle (for example, 45 °). The smaller the predetermined angle is, the shorter the travel distance of the sheet pressing member 50 when the sheet pressing member 50 is laid down or stands up. However, the predetermined angle is an angle that allows the lower edge portion of the waterproof sheet 21 to be inserted between the standing wall surface 8 of the recess 6 and the lateral presser portion 53 in a state in which the sheet presser material 50 is tilted most forward. .

シート押え材50の可動範囲は例えば次の(a)〜(c)のようにして制限される。
(a) 立壁面8の反対側の立壁面9がストッパとして機能する。つまり、シート押え材50が最も前に倒れた状態では、シート押え材50が立壁面9の上端に当接して、シート押え材50の荷重が立壁面9の上端に受けられる。
(b) ヒンジ60によってシート押え材50の可動範囲が制限される。つまり、ヒンジ60の開閉角が定まっており、シート押え材50が最も前に倒れた状態ではヒンジ60がそれ以上動かず、シート押え材50の荷重がヒンジ60に受けられて、ヒンジ60がストッパとして機能する。
(c) 可撓性線材(例えば、紐、ワイヤー、チェーン)がシート押え材50と開口枠40との間に連結され、シート押え材50が最も前に倒れた状態では可撓性線材が張ることによって、シート押え材50がそれ以上前に倒れない。
The movable range of the sheet pressing member 50 is limited, for example, as shown in the following (a) to (c).
(A) The standing wall 9 on the opposite side of the standing wall 8 functions as a stopper. In other words, in the state where the sheet presser material 50 is tilted most forward, the sheet presser material 50 comes into contact with the upper end of the standing wall surface 9 and the load of the sheet presser material 50 is received by the upper end of the standing wall surface 9.
(B) The movable range of the sheet pressing member 50 is limited by the hinge 60. That is, the opening / closing angle of the hinge 60 is fixed, the hinge 60 does not move any more when the sheet pressing member 50 is tilted forward most, the load of the sheet pressing member 50 is received by the hinge 60, and the hinge 60 stops the stopper. Function as.
(C) A flexible wire (for example, a string, a wire, or a chain) is connected between the sheet presser 50 and the opening frame 40, and the flexible wire is stretched when the sheet presser 50 is tilted most forward. As a result, the sheet pressing member 50 does not fall forward any further.

なお、本実施の形態においては、これら切欠部61はシート押え材50に形成されるものとしたが、これに限られるものではなく、開口枠40に形成されてもよいし、開口枠40とシート押え材50の双方に形成されてもよい(図7参照)。
The support bar 22 and the fasteners 23 and 24 are inserted into the pair of vertical presser portions 51 and 52 of the sheet pressing member 50 at the height positions of the support bar 22 and the fasteners 23 and 24 of the waterproof surface member 20, respectively. A cutout 61 is formed.
In the present embodiment, the notches 61 are formed in the sheet pressing member 50. However, the present invention is not limited to this, and may be formed in the opening frame 40. It may be formed on both of the sheet pressing members 50 (see FIG. 7).

開口枠40の前面および凹部6の立壁面8とシート押え材50の後面との間には、それぞれ硬質材からなる凹部と凸部との噛み合わせによって防水シート21を挟持する凹凸噛合構造が設けられている。
すなわち、開口枠40の前面および凹部6の立壁面8とシート押え材50の後面のうち、いずれか一方に凹部が形成され、他方に凸部が形成されており、これら凹部と凸部の噛み合わせに応じて、挟まれた防水シート21も凹部と凸部の表面に沿って変形している。
An uneven engagement structure is provided between the front surface of the opening frame 40 and the standing wall 8 of the recess 6 and the rear surface of the sheet pressing member 50 so that the waterproof sheet 21 is sandwiched by the engagement of the recess made of a hard material and the protrusion.

That is, a concave portion is formed on one of the front surface of the opening frame 40 and the standing wall surface 8 of the concave portion 6 and the rear surface of the sheet pressing member 50, and a convex portion is formed on the other. According to the alignment, the sandwiched waterproof sheet 21 is also deformed along the surfaces of the concave and convex portions.

より具体的に説明すると、開口枠40の前面および凹部6の立壁面8には、開口枠40の前面側から凹部6の立壁面8側にかけて、突条71,72(第一突条71,72)が突出した状態に設けられている。突条71が開口枠40の前面および凹部6の立壁面8の内縁に沿ってU字型に形作られている。突条72が、突条71から開口枠40の前面および凹部6の立壁面8の外縁側へ離れて、突条72と平行となるようにU字型に形作られている。
突条71,72は、U字型に曲げられたステンレスやアルミニウム等の金属製の硬質な丸棒を開口枠40の前面および凹部6の立壁面8に溶接することによって得られたものである。そのため、突条71,72の頂面がシリンドリカル凸面状に形成されている。
ここで、突条71,72のうち縦枠41の前面において縦方向に延びた部位71a,72aを縦突条71a,72aといい、縦枠42の前面において縦方向に延びた部位71b,72bを縦突条71b,72bといい、凹部6の立壁面8において横方向に延びた部位71c,72cを横突条71c,72cという。
なお、突条71,72は、ステンレスやアルミニウム等の金属からなるものとしたが、これに限れるものではなく、硬質樹脂を押出成形してなるものでもよい。
More specifically, on the front surface of the opening frame 40 and the standing wall surface 8 of the recess 6, protrusions 71 and 72 (first protrusions 71, 72) extending from the front surface side of the opening frame 40 to the standing wall surface 8 side of the recess 6. 72) is provided in a protruding state. A protrusion 71 is formed in a U shape along the front surface of the opening frame 40 and the inner edge of the standing wall 8 of the recess 6. The ridge 72 is formed in a U shape so as to be separated from the ridge 71 toward the front surface of the opening frame 40 and the outer edge side of the standing wall surface 8 of the recess 6 and to be parallel to the ridge 72.
The ridges 71 and 72 are obtained by welding a hard round bar made of metal such as stainless steel or aluminum bent into a U-shape to the front surface of the opening frame 40 and the standing wall surface 8 of the recess 6. . Therefore, the top surfaces of the protrusions 71 and 72 are formed in a cylindrical convex shape.
Here, portions 71 a and 72 a extending in the vertical direction on the front surface of the vertical frame 41 of the protrusions 71 and 72 are referred to as vertical protrusions 71 a and 72 a, and portions 71 b and 72 b extending in the vertical direction on the front surface of the vertical frame 42. Are referred to as vertical protrusions 71b and 72b, and portions 71c and 72c extending in the lateral direction on the standing wall surface 8 of the recess 6 are referred to as horizontal protrusions 71c and 72c.
The protrusions 71 and 72 are made of metal such as stainless steel or aluminum. However, the protrusions 71 and 72 are not limited to this, and may be formed by extruding a hard resin.

シート押え材50の後面には、突条73(第二突条73)が突出した状態に設けられている。突条73がシート押え材50のU字型に沿って設けられている。
突条73は、U字型に曲げられたステンレスやアルミニウム等の金属製の硬質な丸棒をシート押え材50の後面に溶接することによって得られたものである。突条73の頂面がシリンドリカル凸面状に形成されている。
ここで、突条73のうち縦押え部51の後面において縦方向に延びた部位73aを縦突条73aといい、縦押え部52の後面において縦方向に延びた部位73bを縦突条73bといい、横押え部53の後面において横方向に延びた部位73cを横突条73cという。
なお、突条73は、ステンレスやアルミニウム等の金属からなるものとしたが、これに限れるものではなく、硬質樹脂を押出成形してなるものでもよい。
On the rear surface of the sheet pressing member 50, a protrusion 73 (second protrusion 73) is provided in a protruding state. A protrusion 73 is provided along the U-shape of the sheet pressing member 50.
The protrusion 73 is obtained by welding a hard round bar made of metal such as stainless steel or aluminum bent into a U shape to the rear surface of the sheet pressing member 50. The top surface of the ridge 73 is formed in a cylindrical convex shape.
Here, a portion 73a extending in the vertical direction on the rear surface of the vertical pressing portion 51 in the protrusion 73 is referred to as a vertical protrusion 73a, and a portion 73b extending in the vertical direction on the rear surface of the vertical pressing portion 52 is referred to as a vertical protrusion 73b. A portion 73c extending in the lateral direction on the rear surface of the lateral pressing portion 53 is referred to as a lateral protrusion 73c.
The protrusion 73 is made of a metal such as stainless steel or aluminum. However, the protrusion 73 is not limited to this, and may be formed by extruding a hard resin.

突条73の幅が突条71から突条72までの間隔に等しい。そして、シート押え材50の後面が開口枠40の前面に突き合わせられた場合に、前から向かって投影視して、突条73が突条71と突条72の間の隙間に重なっている。突条73が突条71と突条72の間の隙間に嵌まって、突条73が突条71,72に櫛歯状に噛み合う。したがって、突条73が突条71の外縁側に隣接し、突条72が突条73の外縁側に隣接する。
この場合、開口枠40および立壁面8における突条71と突条72との間が「凹部」となっており、シート押え材50における突条73が「凸部」となっている。換言すれば、本実施の形態における凹凸噛合構造は、開口枠40の前面および凹部6の立壁面8に突出した状態に設けられた複数の第一突条71,72と、シート押え材50の後面に突出した状態に設けられ一つの第二突条73と、によって構成されている。そして、シート押え材50が開口枠40の前に突き合わせられた状態において第一突条71,72と第二突条73が開口部2の径方向に互いに隣接している。
また、突条71〜73がステンレス鋼のように硬質な材料からなるので、突条71〜73の経年劣化を抑えることができる。
The width of the protrusion 73 is equal to the distance from the protrusion 71 to the protrusion 72. When the rear surface of the sheet pressing member 50 is abutted against the front surface of the opening frame 40, the projection 73 overlaps the gap between the projection 71 and the projection 72 as viewed from the front. The protrusion 73 fits into the gap between the protrusion 71 and the protrusion 72, and the protrusion 73 meshes with the protrusions 71 and 72 in a comb-tooth shape. Therefore, the protrusion 73 is adjacent to the outer edge side of the protrusion 71, and the protrusion 72 is adjacent to the outer edge side of the protrusion 73.
In this case, the space between the ridge 71 and the ridge 72 on the opening frame 40 and the standing wall surface 8 is a “concave portion”, and the ridge 73 on the sheet pressing member 50 is a “convex portion”. In other words, the concave-convex meshing structure in the present embodiment includes a plurality of first protrusions 71 and 72 provided in a state of protruding from the front surface of the opening frame 40 and the standing wall surface 8 of the recess 6, and the sheet pressing member 50. The second protrusion 73 is provided in a state protruding from the rear surface. The first protrusions 71 and 72 and the second protrusion 73 are adjacent to each other in the radial direction of the opening 2 in a state where the sheet pressing member 50 is abutted in front of the opening frame 40.
Moreover, since the ridges 71 to 73 are made of a hard material such as stainless steel, the aging of the ridges 71 to 73 can be suppressed.

なお、2本の突条71,72が開口枠40の後面に設けられているが、開口枠40の前面に設けられる突条の数は3本以上でもよいし、1本でもよい。シート押え材50の後面に設けられる突条の数は2本以上でもよい。

その他にも、図5(b)に示すように、突条71´,72´が開口枠40と一体に押出成形されてなり、突条73´がシート押え材50と一体に押出成形されてなるものでもよい。
さらに、図5(c)に示すように、開口枠40に凹溝74を形成して「凹部」とし、シート押え材50に突条73´を設けて「凸部」としてもよい。この場合、凹溝74と突条73´は同数である。また、図5(c)の例では、開口枠40の前面とシート押え材50の後面との間隔がその突き合わせ時には狭くなるため、防水シート21の膨出部29は、縦枠41(42)および縦押え部51(52)の外側の側面よりも外側に配置される。
なお、図5の各例では、縦枠41(42)および縦押え部51(52)の場合を示しているが、凹部6の立壁面8(または横枠43)と横押え部53の場合も同様に、「凹部」と「凸部」を採用することができる。

Further, as shown in FIG. 5C, a concave groove 74 may be formed in the opening frame 40 to form a “concave portion”, and a protrusion 73 ′ may be provided in the sheet pressing member 50 to form a “convex portion”. In this case, the number of the concave grooves 74 and the protrusions 73 ′ are the same. In the example of FIG. 5C, since the distance between the front surface of the opening frame 40 and the rear surface of the sheet pressing member 50 is narrowed, the bulging portion 29 of the waterproof sheet 21 has a vertical frame 41 (42). And it arrange | positions outside the outer side surface of the vertical pressing part 51 (52).

(B)非常時における防水面材20の設置方法
防水面材20および間柱90を準備する。
次に、蓋99を外して、凹部6を露出させる。
次に、連結手段による開口枠40とシート押え材50の連結を解除する。
次に、図3に示すように、シート押え材50を前に傾動させて、シート押え材50を倒伏させる。こうすることによって、シート押え材50の後面を開口枠40の前面から離すとともに、突条71と突条72の間の隙間から突条73を外す。また、間柱90を設置する。必要に応じて、一または複数の横桟材を縦枠41と縦枠42との間に架け渡したり、一または複数の横桟材を縦枠41と間柱90との間に架け渡したり、一または複数の横桟材を縦枠42と間柱90との間に架け渡したりする。
(B) Installation method of the waterproof face material 20 in an emergency The waterproof face material 20 and the stud 90 are prepared.
Next, the lid 99 is removed to expose the recess 6.
Next, the connection between the opening frame 40 and the sheet pressing member 50 by the connecting means is released.
Next, as shown in FIG. 3, the sheet pressing member 50 is tilted forward, and the sheet pressing member 50 is laid down. In this way, the rear surface of the sheet pressing member 50 is separated from the front surface of the opening frame 40, and the protrusion 73 is removed from the gap between the protrusion 71 and the protrusion 72. Moreover, the stud 90 is installed. If necessary, one or a plurality of horizontal bars are bridged between the vertical frame 41 and the vertical frame 42, or one or a plurality of horizontal bars are bridged between the vertical frame 41 and the stud 90, One or a plurality of crosspieces are bridged between the vertical frame 42 and the intermediate pillar 90.

次に、留め具23,24の通し孔23a,24aに引掛部81,82をそれぞれ挿入して、留め具23,24を引掛部81,82にそれぞれ引っ掛ける。これにより、支持竿22を縦枠41の上部と縦枠42の上部との間に架け渡す。また、留め具28の引掛穴28aにフランジ92および係合凸部91に通して、留め具28を間柱90の上端面に載置するとともに、留め具28の筒状部28bをフック93の上に引っ掛ける。こうすると、支持竿22の中央部が間柱90に支持され、支持竿22の自重による撓みを抑えることができる。   Next, the hook portions 81 and 82 are inserted into the through holes 23a and 24a of the fasteners 23 and 24, respectively, and the fasteners 23 and 24 are hooked on the hook portions 81 and 82, respectively. Thereby, the support rod 22 is bridged between the upper part of the vertical frame 41 and the upper part of the vertical frame 42. Further, the hook 28 is passed through the hooking hole 28 a of the fastener 28 through the flange 92 and the engaging protrusion 91, so that the fastener 28 is placed on the upper end surface of the stud 90, and the tubular portion 28 b of the fastener 28 is placed on the hook 93. Hang on. If it carries out like this, the center part of the support rod 22 will be supported by the stud 90, and the bending by the weight of the support rod 22 can be suppressed.

また、防水シート21を開口枠40および立壁面8の前に垂らして、防水シート21を支持竿22から吊り下げた状態にする。そして、防水シート21の下縁部を下に引っ張り、更に摘み部27,27…を摘んで防水シート21を左右に引っ張り、突条71,72の縦突条71a,72aの前に防水シート21の左縁部を被せ、縦突条71b,72bを前に防水シート21の右縁部を被せ、横突条71c,72cの前に防水シート21の下縁部を被せる。防水シート21を張ることによって目印26を突条71に近づかせることによって、膨出部29の位置が突条72よりも外側になる。こうして、膨出部29を突条72から外側へはみ出た状態にして、左膨出部29aを縦突条72aの左側に配置し、右膨出部29bを縦突条72bの右側に配置し、下膨出部29cを横突条72cの下側に配置する。   Further, the waterproof sheet 21 is hung in front of the opening frame 40 and the standing wall surface 8 so that the waterproof sheet 21 is suspended from the support rod 22. Then, the lower edge portion of the waterproof sheet 21 is pulled downward, the knobs 27, 27... Are further picked, the waterproof sheet 21 is pulled left and right, and the waterproof sheet 21 is placed in front of the vertical protrusions 71a and 72a of the protrusions 71 and 72. The right edge of the waterproof sheet 21 is covered before the vertical protrusions 71b and 72b, and the lower edge of the waterproof sheet 21 is covered before the horizontal protrusions 71c and 72c. By bringing the mark 26 closer to the ridge 71 by stretching the waterproof sheet 21, the position of the bulging portion 29 becomes outside the ridge 72. Thus, with the bulging portion 29 protruding outward from the ridge 72, the left bulging portion 29a is arranged on the left side of the vertical ridge 72a, and the right bulging portion 29b is arranged on the right side of the vertical ridge 72b. The lower bulging portion 29c is disposed below the lateral protrusion 72c.

次に、シート押え材50を後ろに傾動させて、シート押え材50を立てる。こうすることによって、シート押え材50の後面と開口枠40の前面および凹部6の立壁面8との間に防水シート21の周縁部を挟み込んで、シート押え材50の後面を開口枠40の前面および凹部6の立壁面8に突き合わせる。また、シート押え材50の後面と開口枠40の前面および凹部6の立壁面8の突き合わせによって突条71と突条72の間の隙間に突条73を嵌めて、防水シート21の周縁部がこれら突条71〜73の隙間を縫うようにして突条71〜73の噛み合いに巻き込まれる。また、留め具23が縦枠41と縦押え部51の上端部との間に挟まれ、留め具24が縦枠42と縦押え部52の上端部との間に挟まれる。   Next, the sheet pressing member 50 is tilted backward to raise the sheet pressing member 50. By doing so, the periphery of the waterproof sheet 21 is sandwiched between the rear surface of the sheet pressing member 50 and the front surface of the opening frame 40 and the standing wall surface 8 of the recess 6, so that the rear surface of the sheet pressing member 50 is placed on the front surface of the opening frame 40. And abut against the standing wall 8 of the recess 6. Further, the protrusion 73 is fitted into the gap between the protrusion 71 and the protrusion 72 by abutment of the rear surface of the sheet pressing member 50 and the front surface of the opening frame 40 and the standing wall surface 8 of the recess 6, so that the peripheral portion of the waterproof sheet 21 is The gaps between the ridges 71 to 73 are sewn so as to be caught in the engagement of the ridges 71 to 73. Further, the fastener 23 is sandwiched between the vertical frame 41 and the upper end portion of the vertical pressing portion 51, and the fastener 24 is sandwiched between the vertical frame 42 and the upper end portion of the vertical pressing portion 52.

次に、図1に示すように、連結手段によってシート押え材50を開口枠40に連結して、防水装置10の組立が完了する。このような連結によって、防水シート21の周縁部を挟み込む荷重が増大し、防水シート21の周縁部がシート押え材50の後面と開口枠40の前面との間から抜け難くなる。   Next, as shown in FIG. 1, the sheet pressing member 50 is connected to the opening frame 40 by the connecting means, and the assembly of the waterproof device 10 is completed. By such connection, the load sandwiching the peripheral edge portion of the waterproof sheet 21 increases, and the peripheral edge portion of the waterproof sheet 21 is difficult to come out between the rear surface of the sheet pressing member 50 and the front surface of the opening frame 40.

(C)非常時から通常時に復帰したときにおける防水装置10の解体方法
連結手段を外して、連結手段による開口枠40とシート押え材50の連結を解除する。
次に、シート押え材50を前に傾動させて、シート押え材50を倒伏させる。

Then, the waterproof sheet 21 is wound around the support rod 22 to form a rod shape. In addition, the crosspieces are removed from the vertical frames 41 and 42 and the intermediate pillar 90, and the intermediate pillar 90 is removed.
Next, the sheet pressing member 50 is tilted backward, and the rear surface of the sheet pressing member 50 is abutted against the front surface of the opening frame 40. Then, the sheet pressing member 50 is fastened to the opening frame 40 by the connecting means.
Next, the lid 99 is put on the concave portion 6, and the concave portion 6 is closed with the lid 99.

以上の防水装置10は次のような効果をもたらす。   The waterproof device 10 described above provides the following effects.

(1) 開口枠40の前面とシート押え材50の後面との間に設けられ、それぞれ硬質材からなる凹部と凸部との噛み合わせによって防水シート21を挟持する凹凸噛合構造を備えるので、シート押え材50を開口枠40の前に突き合わせると、防水シート21の周縁部を凹部と凸部の隙間を縫うようにして設けることができる。よって、防水シート21によって堰き止められる水の水圧が増えても、防水シート21の周縁部がシート押え材50と開口枠40の間から抜けることを抑えることができる。
また、硬質材である凹部と凸部とが噛み合い、これらの間に防水シート21が挟持されるので、例えば凹部と凸部とが軟質材である場合に比して、防水シート21が受けた水圧に対して高い剛性を発揮する。したがって、防水シート21の周縁部の、シート押え材50と開口枠40の間からの抜け防止に貢献できる。
さらに、凹部と凸部とが硬質材であるので、例えばゴム等の軟質材によって構成される場合に比して劣化しにくくなる。そして、このように凹部と凸部とが劣化しにくい状態であれば、防水シート21の挟み込み時における水密性を長期間にわたって維持できる。
(1) The sheet is provided between the front surface of the opening frame 40 and the rear surface of the sheet pressing member 50, and has a concave-convex meshing structure that sandwiches the waterproof sheet 21 by meshing a concave portion and a convex portion each made of a hard material. When the pressing member 50 is abutted in front of the opening frame 40, the peripheral edge portion of the waterproof sheet 21 can be provided so as to sew the gap between the concave portion and the convex portion. Therefore, even if the water pressure blocked by the waterproof sheet 21 increases, it is possible to prevent the peripheral edge of the waterproof sheet 21 from coming off between the sheet pressing member 50 and the opening frame 40.
Moreover, since the recessed part and convex part which are hard materials mesh | engage and the waterproof sheet 21 is pinched | interposed between these, the waterproof sheet 21 received compared with the case where a recessed part and a convex part are soft materials, for example. Exhibits high rigidity against water pressure. Therefore, it is possible to contribute to preventing the peripheral edge portion of the waterproof sheet 21 from coming off between the sheet pressing member 50 and the opening frame 40.
Furthermore, since the concave portion and the convex portion are hard materials, they are unlikely to deteriorate as compared with a case where the concave portions and the convex portions are made of a soft material such as rubber. And if it is in the state where a recessed part and a convex part are hard to deteriorate in this way, the water-tightness at the time of pinching of the waterproof sheet 21 can be maintained over a long period of time.

(2) 開口枠40の前面とシート押え材50の後面との間に間隔を空けたい時に、第一突条71,72と第二突条73の突出分の間隔を空けることができる。 (2) When it is desired to leave a gap between the front surface of the opening frame 40 and the rear surface of the sheet pressing member 50, the first protrusions 71 and 72 and the second protrusion 73 can be spaced apart.

(3) 第一突条71,72が開口枠40と一体に押出成形されてなり、第二突条73がシート押え材50と一体に押出成形されてなるので、例えば第一突条71,72と第二突条73が後付けされる場合に比して強度に優れ、水圧を受ける防水シート21をより確実に挟み込むことができる。 (3) Since the first protrusions 71 and 72 are integrally formed with the opening frame 40 and the second protrusion 73 is integrally formed with the sheet pressing member 50, for example, the first protrusions 71 and 72 are formed. Compared with the case where 72 and the 2nd protrusion 73 are retrofitted, it is excellent in intensity | strength and the waterproof sheet 21 which receives a water pressure can be pinched more reliably.

(4) 開口枠40が開口部2の左右両側部と下縁部とを構成するので、防水シート21を張って防水シート21の周縁部を開口枠40の前に配置した状態で、シート押え材50を開口枠40の前に突き合わせてシート押え材50を開口枠40に押し当てることによって、防水シート21の下縁部および側縁部をいっぺんにシート押え材50と開口枠40の間に挟み込むことができる。面状の防水シート21の下縁部と側縁部をその面に垂直な方向に押さえるので、防水シート21によって早く確実に止水面を形成することができる。 (4) Since the opening frame 40 constitutes the left and right sides and the lower edge of the opening 2, the sheet retainer is placed in a state where the waterproof sheet 21 is stretched and the periphery of the waterproof sheet 21 is disposed in front of the opening frame 40. The sheet 50 is abutted in front of the opening frame 40 and the sheet pressing member 50 is pressed against the opening frame 40, thereby sandwiching the lower edge portion and the side edge portion of the waterproof sheet 21 between the sheet pressing member 50 and the opening frame 40 together. be able to. Since the lower edge portion and the side edge portion of the sheet-shaped waterproof sheet 21 are pressed in the direction perpendicular to the surface, the waterproof sheet can quickly and reliably form the water stop surface.

(5) 横枠が開口部2の下縁部を構成し、一対の縦枠41,42が開口部2の左右の縁を構成するので、防水シート21を張って防水シート21の左右の縁部を左右の縦枠41,42の前に配置し、防水シート21の下縁部を横枠前に配置した状態で、シート押え材50の横押え部53および縦押え部51,52をそれぞれ開口枠40の横枠および縦枠41,42の前に突き合わせることによって、防水シート21の下縁部、左縁部および右縁部をいっぺんにシート押え材50と開口枠40の間に挟み込むことができる。よって、防水シート21によって止水面を早く確実に形成することができる。
また、シート押え材50がその下端を軸として前後に傾動可能に設けられているため、シート押え材50を後ろに傾動させるだけで、防水シート21の少なくとも下縁部、左縁部および右縁部をいっぺんにシート押え材50と開口枠40の間に挟み込むことができる。よって、防水シート21よって止水面を早く確実に形成することができる。
(5) Since the horizontal frame constitutes the lower edge of the opening 2 and the pair of vertical frames 41 and 42 constitute the left and right edges of the opening 2, the waterproof sheet 21 is stretched and the left and right edges of the waterproof sheet 21 In the state where the portion is disposed in front of the left and right vertical frames 41 and 42 and the lower edge portion of the waterproof sheet 21 is disposed in front of the horizontal frame, the lateral pressing portion 53 and the vertical pressing portions 51 and 52 of the sheet pressing member 50 are respectively The bottom edge, the left edge and the right edge of the waterproof sheet 21 are sandwiched between the sheet pressing member 50 and the opening frame 40 at the same time by butting in front of the horizontal frame and the vertical frames 41 and 42 of the opening frame 40. Can do. Therefore, the waterproof surface can be quickly and reliably formed by the waterproof sheet 21.
Further, since the sheet pressing member 50 is provided so as to be tiltable back and forth with its lower end as an axis, at least the lower edge portion, the left edge portion and the right edge of the waterproof sheet 21 can be obtained simply by tilting the sheet pressing material 50 backward. The portions can be sandwiched between the sheet pressing member 50 and the opening frame 40 all at once. Therefore, the waterproofing surface can be quickly and reliably formed by the waterproof sheet 21.
