Description
本発明は、建物の開口を封鎖して外部からの水を堰き止め、内部への水の侵入を阻止するための止水板を支持する止水板用支持柱の設置構造に関し、特に開口間口が広く、水圧によって止水板が建物内部側に撓んで止水性を担保できない場合や、止水板が破損することを防止するため、止水板の後方に配置して止水の信頼性を向上させる止水板用支持柱の設置構造に関する。 The present invention relates to an installation structure of a support column for a water stop plate that blocks a building opening, blocks water from the outside, and supports a water stop plate for preventing water from entering the inside. Are placed behind the water blocking plate to prevent the water blocking plate from being damaged if the water blocking plate is bent to the inside of the building by water pressure and the water blocking plate can not be secured. The present invention relates to an installation structure of a water blocking plate support column to be improved.
止水板の構造や構成には、例えば特許文献1及び2に見られるような、コの字状の枠に止水板を保持させるものや、単立させるもの等が知られている。これら従来の止水板は、通常時は別の場所に保管され、有事の際に使用者が運搬して建物開口に設置することが多いため、サイズや重量等が人力に相当するものでなければならない。 As the structure and configuration of the water blocking plate, for example, those in which the water blocking plate is held in a U-shaped frame as is seen in Patent Documents 1 and 2 and those in which the water standing plate is erected are known. These conventional waterstops are usually stored in a separate place and are often transported by users in the event of an emergency and installed at the building opening, so the size, weight, etc. must be equivalent to human power. I must.
このため、軽量な構成が優先されて、耐水圧が不足する場合が散見される。また、建物開口の間口が広いと、そこに設置した止水板の撓み量が必然的に大きくなる。更に、幅寸法が数メートルに及ぶと人間による運搬が困難となるため、一定程度の幅寸法の止水板を間口方向に複数連結して設置する必要があり、その際の連結部分の止水性や、開き及び破損を防止可能な耐水圧を向上する支持力が必要となる。 For this reason, priority is given to a lightweight structure, and the case where water-resistant pressure is insufficient is occasionally seen. Moreover, if the frontage of a building opening is wide, the amount of deflection of the water stop plate installed there inevitably increases. Furthermore, since it is difficult to carry by humans when the width dimension reaches several meters, it is necessary to install a plurality of waterstop plates with a certain width dimension in the frontage direction, and the waterstop of the connection part at that time In addition, a supporting force for improving the water pressure resistance that can prevent opening and breakage is required.
しかしながら、上記問題を解決するためには、開口域の床面に止水板用支持柱を立設し、水圧による撓みの軽減や止水板同士の連結部分の止水性等の向上が必要となるが、極めて大きな水圧に耐え、止水板の傾きや破損を防止可能な止水板用支持柱の設置方法を提供することが急務であった。 However, in order to solve the above-mentioned problem, it is necessary to erect a water-stop plate support column on the floor surface of the opening area, and to reduce the deflection due to water pressure and improve the water-stop performance of the connection portion of the water-stop plates. However, it was urgent to provide a method for installing a water blocking plate support column that can withstand extremely high water pressure and prevent the tilt and breakage of the water blocking plate.
そこで本発明は、上記問題に鑑みて創造されたものであり、高い耐水圧性等を備えながら、簡便容易に止水板用支持柱を設置可能とする止水板用支持柱の設置構造を提供することを目的とする。 Then, this invention is created in view of the said problem, provides the installation structure of the support pillar for water blocking boards which enables installation of the support column for water blocking boards simply and easily while having high water pressure resistance etc. The purpose is to do.
上記の課題を解決すべく、本発明は、
建物開口を封鎖して外部からの流入水を止水する止水板を支持する止水板用支持柱の設置構造であって、
前記止水板用支持柱は、下端側が開口域床面を陥入させて形成した竪孔に嵌装され、上方に止水板と当接して支持する止水板当接面を有し、前記止水板用支持柱の前記下端側及び前記竪孔に当接する補助具が嵌装されていること、
を特徴とする止水板用支持柱の設置構造を提供する。
In order to solve the above problems, the present invention is
An installation structure of a water blocking plate support column for supporting a water blocking plate for closing an opening of the building to stop water flowing from the outside, comprising:
The water stop plate support column is fitted in a fistula formed by indenting the floor surface of the opening area at the lower end side, and has a water stop plate contact surface that supports and supports the water stop plate above. The lower end side of the support column for water blocking plate and an auxiliary tool to be in contact with the weir are fitted.
An installation structure of a water blocking plate support column characterized by
このような構成を有する本発明の止水板用支持柱の設置構造では、止水板用支持柱が竪孔に嵌装固定されるため、高い耐水圧性を持ち、補助具を嵌装した構成のために、止水板用支持柱が竪孔内に確実に固定されて、止水板用支持柱と竪孔との間に密着面を形成することができ、良好な止水性が得られる。更に、本来は竪孔と止水板用支持柱との固定及び密着を達成するためには、止水板用支持柱と竪孔との間に隙間が生じてはならないが、竪孔と止水板用支持柱との間(建物内部側)に補助具を嵌装することで、止水板用支持柱を竪孔内に確実に固定させることができる。なお、本発明における「補助具」とは、竪孔と止水板用支持柱との間に嵌装されて、止水板用支持柱を竪孔内に確実に固定して密着させるための楔(くさび)材であり、かかる固定・密着をバックアップするバックアップ材乃至は嵌装材とも言える。 In the installation structure of the water blocking plate support column of the present invention having such a configuration, the water blocking plate support column is fitted and fixed in the hole, so that it has high water pressure resistance and is fitted with an auxiliary tool. Therefore, the support pillar for the water stop plate is securely fixed in the fistula, and a close contact surface can be formed between the support pillar for the water stop plate and the fistula, and good water stoppage can be obtained. . Furthermore, originally, in order to achieve fixation and close contact between the well and the water blocking plate support column, a gap should not occur between the water blocking plate supporting column and the well but the well By fitting the auxiliary tool between the water plate support column (inside of the building), the water blocking plate support column can be reliably fixed in the stoma. The “auxiliary tool” in the present invention is fitted between the water hole and the water blocking plate support column, and is used to securely fix and closely contact the water blocking plate support column in the water hole. It is a wedge material and can also be said to be a backup material or a fitting material that backs up such fixing and adhesion.
また、上記の本発明の止水板用支持柱の設置構造においては、
前記止水板用支持柱、前記竪孔及び前記補助具は、それぞれ複数の竪面を具備し、
前記止水板用支持柱が前記竪孔に嵌装されて、前記竪孔の前記竪面と当接するA1当接竪面及び前記補助具と当接するA2当接竪面を備え、
前記補助具が前記竪孔に嵌装されて、前記竪孔の前記竪面と当接するB2当接竪面及び前記止水板用支持柱のA2当接竪面と当接するB1当接竪面を備えることが望ましい。
Further, in the installation structure of the above water blocking plate support column of the present invention,
The water blocking plate support column, the fistula and the auxiliary tool each have a plurality of weir faces,
The water stop plate support pillar is fitted in the hole, and includes an A1 contact flange surface that contacts the flange surface of the hole and an A2 contact flange surface that contacts the auxiliary tool,
The auxiliary tool is fitted in the shaft hole, and the B2 contact flange surface that contacts the flange surface of the hole and the B1 contact flange surface that contacts the A2 contact flange surface of the water column support pillar. It is desirable to provide.
このような構成を有する本発明の止水板用支持柱の設置構造では、上述した各面が当接するため止水性が向上し、竪孔と止水板用支持柱との間から水が浸入することを好適に防止することができる。 In the installation structure of the support pillar for the water stop plate of the present invention having such a configuration, the water stoppage is improved because the above-described surfaces come into contact with each other, and water enters from between the fistula and the support pillar for the water stop plate. This can be suitably prevented.
また、上記の本発明の止水板用支持柱の設置構造においては、前記止水板用支持柱の前記A1当接竪面と前記A2当接竪面とが前記止水板用支持柱の反対面に設置され、かつ前記補助具の前記B1当接竪面と前記B2当接竪面とが前記補助具の反対面に配設されていることが望ましい。即ち、前記止水板用支持柱において、前記A1当接竪面の反対側に前記A2当接竪面が位置する、乃至は、前記A1当接竪面と前記A2当接竪面とが背中合わせに対向するように位置する。また、前記補助具において、前記B1当接竪面の反対側に前記B2当接竪面が位置する、乃至は、前記B1当接竪面と前記B2当接竪面とが背中合わせに対向するように位置する。 In the installation structure of the water stop plate support column of the present invention, the A1 contact flange surface and the A2 contact flange surface of the water stop plate support column are the water stop plate support column. Preferably, the B1 contact wedge surface and the B2 contact wedge surface of the auxiliary tool are disposed on the opposite surface of the auxiliary tool. That is, in the water blocking plate support column, the A2 abutment wedge surface is located on the opposite side of the A1 abutment wedge surface, or the A1 abutment wedge surface and the A2 abutment wedge surface are back-to-back It is located so as to face. In the auxiliary tool, the B2 abutment wedge surface is located on the opposite side of the B1 abutment wedge surface, or the B1 abutment wedge surface and the B2 abutment wedge surface face back to back. Located in.
このような構成を有する本発明の止水板用支持柱の設置構造では、各当接竪面が同一方向に配列されるため、隙間の発生を防止して止水性を向上することができる。また、各当接竪面の配列方向が建物開口の前後方向(建物外部側及び建物内部側)と合致し、かつ補助具が建物開口の後方側に位置する場合は、水圧によって止水板用支持柱の上端側が後方に押され、止水板用支持柱が建物内部側に傾斜するよう水圧が負荷される。これにより、止水板用支持柱の下端側は竪孔の竪面によって強く密接するため、止水性を更に向上することができる。 In the installation structure of the water-stop plate support pillar of the present invention having such a configuration, since the contact flange surfaces are arranged in the same direction, the generation of a gap can be prevented and the water-stop performance can be improved. In addition, when the arrangement direction of each contact ridge surface matches the longitudinal direction of the building opening (building outside and building inside), and the auxiliary tool is located behind the building opening, for water blocking board by water pressure The upper end side of the support column is pushed backward, and water pressure is applied so that the water stop plate support column is inclined toward the inside of the building. Thereby, since the lower end side of the support pillar for water stop plates is closely contacted by the ridge surface of the fistula, water stop can be further improved.

このような構成を有する本発明の止水板用支持柱の設置構造では、柔軟な止水材が止水効果を奏する程度の圧縮代で圧縮するように補助具の寸法が設定されていれば、止水板用支持柱と竪孔の止水性を向上できるだけでなく、止水板用支持柱を嵌装する際に、止水材を傷付けたり、止水材が止水板用支持柱又は竪孔から剥がれる等の不具合を防止することができる。即ち、竪孔に密着して止水板用支持柱を嵌装するには柔軟で傷付きやすい止水材が破損する懸念があるが、本発明の止水板用支持柱の設置構造では、余裕を持って止水板用支持柱を嵌装した後、補助具を嵌装させて止水板用支持柱と竪孔とを密着させるため、当該懸念を解消することができる。 In the installation structure of the support pillar for the water stop plate of the present invention having such a configuration, if the dimensions of the auxiliary tool are set so that the flexible water stop material compresses with a compression allowance that exhibits a water stop effect. In addition to improving the water-stopping performance of the water-stop plate support column and the fistula, when fitting the water-stop plate support column, the water-stop material may be damaged or the water-stop material may be Problems such as peeling from the fistula can be prevented. That is, there is a concern that the waterproof and easy-to-scratch water-stopping material may be damaged to fit the water-stop support pillar in close contact with the fistula, but in the installation structure of the water-stop support pillar of the present invention, After the support column for water blocking plate is fitted with a margin, the auxiliary tool is fitted and the support column for water blocking plate and the weir are brought into close contact, so that the concern can be resolved.

このような構成を有する本発明の止水板用支持柱の設置構造では、竪孔に止水板用支持柱を嵌装した後、止水板用支持柱と竪孔との間に補助具を嵌装する際に、上方から力をかけて補助具を容易に嵌装することができる。種々の押圧方法を用いることができ、例えば当該押圧面を足で踏み込むことで踏力を付加させたり、手のひらで押し込んだり、木槌のようなハンマーでたたき込んだりすることができる。 In the installation structure of the water blocking plate support column of the present invention having such a configuration, after the water blocking plate support column is fitted in the hole, an auxiliary tool is provided between the water blocking plate support column and the hole. When fitting, the auxiliary tool can be easily fitted by applying a force from above. Various pressing methods can be used. For example, a pedaling force can be applied by stepping on the pressing surface with a foot, a pressing force can be applied with a palm, or a hammer such as a mallet can be used.
また、上記の本発明の止水板用支持柱の設置構造においては、前記止水板用支持柱の前記A2当接竪面が左右に隔離形成されていることが望ましい。この構成を採ることで、左右のA2当接竪面間に支持柱奥向きに溝状の空間を生じさせることができる。 Further, in the installation structure of the water blocking plate support column of the present invention, it is preferable that the A2 contact wedge surface of the water blocking plate support column is formed to be separated to the left and right. By adopting this configuration, a groove-like space can be created between the left and right A2 contact saddle surfaces toward the back of the support column.
このような構成を有する本発明の止水板用支持柱の設置構造では、止水板用支持柱を例えばC字形(略リップ溝形鋼と同様の断面形状)断面形状等とすれば、補助具の厚さ寸法が比較的薄いものでも均等に上方から下方に押圧することができる。さらに、足、手のひらで押し込む際に、支持柱の前記した溝状の空間につま先側や指先側を逃がすことができ、押し込みが容易で、押し込み力を適切に伝えることもできるので、作業性を向上できる。 In the installation structure of the water blocking plate support column of the present invention having such a configuration, if the water blocking plate support column has, for example, a C-shaped cross-sectional shape similar to that of the lip grooved steel, Even if the thickness of the tool is relatively thin, it can be uniformly pressed from above to below. In addition, when pushing in with the foot or palm, the toe side or fingertip side can be released into the groove-shaped space of the support column, the pushing is easy, and the pushing force can be transmitted appropriately, so workability is improved. It can be improved.
本発明では更に、前記竪孔に前記止水板用支持柱を嵌装した後、前記止水板用支持柱と前記竪孔との間に前記補助具を嵌装して請求項1から6のいずれかに記載の止水板用支持柱の設置構造を構成する止水板用支持柱の設置方法も提供することができる。 Furthermore, in the present invention, after the water blocking plate support column is fitted into the hole, the auxiliary tool is fitted between the water blocking plate support column and the hole. It is also possible to provide an installation method for a water stop plate support column that constitutes the installation structure of the water stop plate support column described in any of the above.

It is desirable that the water blocking material 19 be disposed so as to project upward from the above-mentioned fitting upper end edge P3, and the pressing force accompanying the installation of the water blocking plate 107 causes the water blocking material 19 to be compressed to exert a water blocking effect. Can do. As described above, by sticking the water blocking material 19 to the column body 23, the outer surface of the water blocking material 19 (the opposite side of the bonding surface) becomes the A1 contact wedge surface 11.
止水材19の各部の寸法は、止水板用支持柱1のサイズに応じて適宜決定すればよいが、高さ方向の寸法は10mm〜80mm程度とし、厚さ寸法は1mm〜10mm程度で、押圧時は0.5mm〜3mm程度に圧縮されることが望ましい。また、図2(c)に示すとおり、嵌装上端縁P3から上方に突出させる寸法は5mm以内、より好ましくは1mm〜3mm程度とすることが望ましい。 The dimensions of each part of the water stop material 19 may be appropriately determined according to the size of the support pillar 1 for the water stop plate, but the dimension in the height direction is about 10 mm to 80 mm, and the thickness dimension is about 1 mm to 10 mm. When pressed, it is desirable to compress to about 0.5 mm to 3 mm. Further, as shown in FIG. 2C, it is desirable that the dimension to be projected upward from the fitting upper end edge P3 be within 5 mm, more preferably about 1 mm to 3 mm.
また、柱体23のA1当接竪面11の下方部は、前方に突出した突出部20が設けられている。止水板107に水圧がかかると、止水板用支持柱1は後方(傾斜上端側が建物内部側に傾くように傾斜)に傾斜するが、大きく傾斜すると止水板用支持柱1と竪孔3との止水性を阻害することになり、止水板107と建物開口や床面との止水にも影響されることになる。しかし、前記した突出部20があれば、突出部20が竪孔3の竪面9に当接するので、それ以上の止水板用支持柱1の傾斜を防止できる。 Further, a projecting portion 20 projecting forward is provided at a lower portion of the A1 contact saddle surface 11 of the column body 23. When water pressure is applied to the water blocking plate 107, the water blocking plate support pillar 1 is inclined rearward (the upper end side is inclined to the inside of the building), but when it is greatly inclined, the water blocking plate support pillar 1 and the weir 3 and the water stoppage between the waterstop plate 107 and the building opening or floor surface. However, if the above-described protrusion 20 is present, the protrusion 20 abuts on the weir surface 9 of the weir 3 so that it is possible to prevent further inclination of the water blocking plate support pillar 1.
突出部20の突出高さ寸法は、止水材19の寸法及び圧縮率等によって決定することが望ましいが、例えば1mm〜2mm程度とすることが望ましい。 Although it is desirable to determine the protrusion height dimension of the protrusion part 20 by the dimension of the water stop material 19, a compression rate, etc., it is desirable to set it as 1 mm-about 2 mm, for example.
3.補助具5の構造
続いて、図4(a)及び(b)を用いて補助具5の構造について詳細に説明する。図4(a)及び(b)は、補助具5の構造を示す図であって、図4(a)は、補助具5の正面図であり、図4(b)は、補助具5の右側面図である。補助具5の正面は、止水板用支持柱1と当接するB1当接竪面15となっており、補助具5の背面は、竪孔3の竪面9と当接するB2当接竪面17となっている。
3. Structure of Auxiliary Tool 5 Subsequently, the structure of the auxiliary tool 5 will be described in detail with reference to FIGS. 4 (a) and 4 (b). 4 (a) and 4 (b) are diagrams showing the structure of the auxiliary tool 5, and FIG. 4 (a) is a front view of the auxiliary tool 5, and FIG. 4 (b) is a view of the auxiliary tool 5.

The front surface of the assisting tool 5 is a B1 abutting saddle surface 15 that abuts against the water blocking plate support column 1, and the rear surface of the assisting tool 5 is a B2 abutting saddle surface that abuts against the collar surface 9 of the fistula 3. 17
補助具5は、ステンレスやアルミニウム等の耐蝕性を有した金属材料、高剛性を有した樹脂材料又はゴム等で形成された扁平状の部品である。各部の寸法は、止水板用支持柱1及び竪孔3の寸法等から適宜決定すればよいが、より確実に止水板用支持柱1を設置するためには、B1当接竪面15の幅寸法は上述した止水板用支持柱1のA1当接竪面11及びA2当接竪面13の幅寸法L4と略同寸法とし、厚さ寸法T1は2cm〜10cm程度とすることが望ましい。 The auxiliary tool 5 is a flat component made of a metal material having corrosion resistance such as stainless steel or aluminum, a resin material having high rigidity, or rubber. The dimensions of each part may be appropriately determined from the dimensions of the water stop plate support column 1 and the hole 3 and the like, but in order to install the water stop plate support column 1 more reliably, the B1 abutting surface 15 The width dimension of A1 is approximately the same as the width dimension L4 of the A1 contact wedge surface 11 and the A2 contact wedge surface 13 of the water blocking plate support pillar 1 described above, and the thickness dimension T1 is about 2 cm to 10 cm desirable.
補助具5の上方には、使用者が操作する際に把持する把持部33が備わっているため、容易に運搬でき、竪孔3への着脱も簡便になる。下方は、B1当接竪面15を除く他の面が所定の角度で傾斜したテーパにより構成された先端部37を形成している。補助具5に先端部37を設けることにより、補助具5を容易に竪孔3へ嵌装することが可能となる。なお、上方の端面は、補助具5を竪孔3に嵌装する際、使用者が押圧するための押圧面35である(把持部33介して押圧することもできる。)。 The upper portion of the assisting tool 5 is provided with the gripping portion 33 which is gripped when the user operates it, so that it can be easily transported, and attachment to and removal from the fistula 3 becomes simple. The lower side forms a tip portion 37 formed by a taper in which the other surfaces except the B1 contact flange surface 15 are inclined at a predetermined angle. By providing the distal end portion 37 on the auxiliary tool 5, the auxiliary tool 5 can be easily fitted into the fistula 3. The upper end face is a pressing surface 35 for the user to press when the auxiliary tool 5 is fitted into the fistula 3 (it can also be pressed via the grip portion 33).
4.竪孔3の構造
次に、図5(a)及び(b)を用いて竪孔3の構造について詳細に説明する。図5(a)及び(b)は、竪孔3の構造を示す図であって、図5(a)は、竪孔3を上方から見た平面図であり、図5(b)は、図5(a)に示す矢視Aの断面図である。竪孔3は、建物開口101近傍の床面109に配設し、上記止水板用支持柱1を嵌装して設置する孔である。
4. Structure of fistula 3 Next, the structure of the fistula 3 will be described in detail using FIGS. 5A and 5B. 5 (a) and 5 (b) are diagrams showing the structure of the fistula 3, and FIG. 5 (a) is a plan view of the fistula 3 as viewed from above, and FIG. 5 (b) is It is sectional drawing of arrow A shown to Fig.5 (a). The weir 3 is a hole which is disposed on the floor surface 109 in the vicinity of the building opening 101 and in which the water blocking plate support pillar 1 is fitted and installed.
竪孔3は、床面109に対して所定の掘削を施し、コンクリートやモルタル、耐蝕性を有する金属材料、高剛性を有する樹脂又はゴム等を用いて複数の竪面9を形成し、上面のない箱状を形成すればよい。また、建物内部側103に位置する竪面9は、補助具5の先端部37と嵌合する等の所望の理由により、図5に示すように、下方が所定の角度で傾斜した斜面45が配設されて底面43とつながるようにしてもよい。 The pits 3 are excavated in a predetermined manner on the floor surface 109 to form a plurality of pit surfaces 9 using concrete, mortar, corrosion-resistant metal material, resin or rubber having high rigidity, etc. What is necessary is just to form the box shape which is not. In addition, as shown in FIG. 5, the wedge surface 9 located on the interior side 103 of the building has a slope 45 inclined downward at a predetermined angle, as shown in FIG. It may be arranged so as to be connected to the bottom surface 43.
竪孔3の寸法は、上述した止水板用支持柱1及び補助具5の寸法に応じて適宜決定すればよく、深さ寸法L1は、5cm〜50cm程度、建物開口101の間口方向の幅寸法L7は、5cm〜50cm、建物外部側105及び建物内部側103方向の幅寸法L2は、5cm〜50cm、また、上述した斜面45の幅寸法L3は、補助具5の厚さ寸法T1と略同様にすることが望ましい。 What is necessary is just to determine the dimension of the hole 3 suitably according to the dimension of the support pillar 1 for water-stopping plates mentioned above, and the auxiliary tool 5, and the depth dimension L1 is about 5-50 cm, and is the width | variety of the opening direction of the building opening 101 The dimension L7 is 5 cm to 50 cm, the width dimension L2 in the direction of the building exterior side 105 and the building interior side 103 is 5 cm to 50 cm, and the width dimension L3 of the slope 45 described above is approximately the thickness dimension T1 of the aid 5 It is desirable to do the same.
なお、竪孔3に対する止水板用支持柱1及び補助具5の嵌装の作業性を向上するため、各部の固定が著しく低下しない程度に上記各部の寸法にクリアランスを加えて構成してもよい。 In addition, in order to improve the workability of fitting the support column 1 for water blocking plate and the auxiliary tool 5 to the weir 3, even if it is configured by adding a clearance to the dimensions of the above-mentioned parts, the fixation of each part is not significantly reduced. Good.
図5(b)に示すとおり、各竪面9の上端部を折り曲げて拡幅し、後述の蓋41を嵌合させるための蓋当接面39が設けられている。床面のグランド高さと蓋当接面39の高さの差、即ち蓋当接面39の落ち込み高さを、蓋41の周縁部厚みと略同じとすることで、止水板用支持柱1を使用しない際に蓋41で竪孔3を塞いでも、床面に段差を生じないように平坦にすることができる。 As shown in FIG. 5B, a lid contact surface 39 is provided for bending and widening the upper end portion of each wedge surface 9 and fitting a lid 41 described later. By making the difference between the ground height of the floor surface and the height of the lid contact surface 39, ie, the falling height of the lid contact surface 39, substantially the same as the peripheral thickness of the lid 41, the water blocking plate support pillar 1 Even when the lid 3 is closed with the lid 41 when not used, the floor can be flattened so as not to cause a step.
次に、図6(a)及び(b)を用いて蓋41の構造を詳細に説明する。図6(a)及び(b)は、蓋41の構造を示す図であって、図6(a)は、蓋41を上方から見た平面図であり、図6(b)は、図6(a)に示す矢視Bの断面図である。蓋41は、止水板用支持柱1を使用しない際に、上述した竪孔3を塞ぐ部品である。 Next, the structure of the lid 41 will be described in detail with reference to FIGS. 6 (a) and 6 (b). 6 (a) and 6 (b) are diagrams showing the structure of the lid 41, and FIG. 6 (a) is a plan view of the lid 41 as viewed from above, and FIG. 6 (b) is a plan view. It is sectional drawing of the arrow B shown to (a). The lid 41 is a component that closes the above-described fistula 3 when the waterstop support pillar 1 is not used.
図6(a)及び(b)に示すとおり、蓋41は、略矩形の板状部品であって、一方の面に可動式把持部47が配設されている。蓋41の寸法は、上記可動式把持部47が収納可能な厚さで、上述した竪孔3の蓋当接面39に当接して嵌合可能な寸法とすることが望ましい。可動式把持部47は、蓋41との接続部がヒンジとなっており、該ヒンジを軸にして蓋41から起立させることができる。また、非起立時に可動式把持部47が蓋41内に収納できるよう、例えば可動式把持部47の形状に相似した凹部を蓋41に形成すれば、蓋41を竪孔3に嵌合させた際に可動式把持部47を収納して蓋41を平滑な状態とすることができる。また、可動式把持部47と蓋41との接続は、上記したようなヒンジ方式を適用できるほか、直立した逆U字状の可動式把持部47の両下端側を上下に摺動可能な貫通孔を蓋41に設けておき、その孔に可動式把持部47の両下端側を落とし込んで収納する、所謂落とし込み式を採用してもよい(その際は、可動式把持部47と蓋41とが離隔してしまわないように、可動式把持部47の下端側に突出部を設けて抜け止めとすればよい。)。 As shown in FIGS. 6 (a) and 6 (b), the lid 41 is a substantially rectangular plate-like component, and the movable gripping portion 47 is disposed on one surface. It is desirable that the dimension of the lid 41 be such a dimension that can be fitted in contact with the lid contact surface 39 of the above-mentioned fistula 3 with a thickness that can accommodate the movable grip portion 47 described above. The movable grip portion 47 has a hinge connected to the lid 41 as a hinge, and can be erected from the lid 41 about the hinge. Moreover, if the recessed part similar to the shape of the movable gripping part 47 is formed in the lid 41 so that the movable gripping part 47 can be accommodated in the lid 41 when not standing, the lid 41 is fitted into the fistula 3. At this time, the movable gripping portion 47 can be accommodated to make the lid 41 smooth. Further, the movable gripping portion 47 and the lid 41 can be connected to each other by using the hinge method as described above, or through the lower end of the upright inverted U-shaped movable gripping portion 47 that can slide up and down. A so-called drop type in which holes are provided in the lid 41 and both lower ends of the movable gripping portion 47 are dropped into the holes and stored may be adopted (in that case, the movable gripping portion 47 and the lid 41 It is sufficient to provide a protrusion on the lower end side of the movable gripping portion 47 so as to prevent it from separating.
5.止水板107の設置方法
次に、図7、図8及び図9を用いて、止水板用支持柱1と、竪孔3と、補助具5と、を用いた止水板107の設置方法を詳細に説明する。図7は止水板用支持柱1と、補助具5と、を竪孔3に嵌装する状況を示す模式図であり、図8は竪孔3に嵌装した止水板用支持柱1及び補助具5における建物内部側103から建物外部側105方向の断面図であり、図9は止水板107を建物開口101に設置した状態を上方から床面109を見た平面図である。
5. Installation Method of Water Sealing Plate 107 Next, referring to FIGS. 7, 8 and 9, installation of the water sealing plate 107 using the water blocking plate support pillar 1, the weir 3 and the auxiliary tool 5. The method will be described in detail. FIG. 7 is a schematic view showing a situation where the water stop plate support pillar 1 and the auxiliary tool 5 are fitted in the fistula 3, and FIG. 8 is a water stop plate support pillar 1 fitted in the fisthole 3. FIG. 9 is a cross-sectional view of the auxiliary tool 5 from the building interior side 103 to the building exterior side 105 direction, and FIG. 9 is a plan view of the floor 109 as viewed from above with the water stop plate 107 installed in the building opening 101.
まず、図7に示すとおり、竪孔3に嵌合している蓋41を取り外して竪孔3を開口させた後、止水板用支持柱1の把持部25を把持し、止水板当接面7を建物外部側105に対向させつつ、竪孔3の建物外部側105に位置する竪面9にA1当接竪面11が当接するよう、竪孔3内に止水板用支持柱1を嵌装する。 First, as shown in FIG. 7, after removing the lid 41 fitted in the hole 3 and opening the hole 3, the holding part 25 of the water-stop plate support pillar 1 is held and the water-stop plate Support column for water blocking plate in the weir 3 so that the A1 contact weir surface 11 abuts on the weir surface 9 located on the building exterior side 105 of the weir 3 while making the contact surface 7 face the building exterior side 105 1 is fitted.
続いて、補助具5の把持部33を把持して止水板用支持柱1のA2当接竪面13にB1当接竪面15を当接し、竪孔3の建物内部側103に位置する竪面9とB2当接竪面17が当接するよう、竪孔3内の、止水板用支持柱1の後方(建物内部側103)に補助具5を嵌装する。これに際し、補助具5押圧面35を押圧することで、嵌装を容易に行うことができる。なお、この嵌装の最初の段階で、先窄まり状に形成された先端部37を竪孔3(止水板用支持柱1のA2当接竪面13と、竪孔3の建物内部側103に位置する竪面9との間)に挿入して全体を誘導することで容易に補助具5を竪孔3に嵌装することができる。 Subsequently, the gripping portion 33 of the auxiliary tool 5 is gripped, the B1 contact saddle face 15 is brought into contact with the A2 contact saddle face 13 of the water blocking plate support pillar 1, and is located on the building interior side 103 of the hole 3. The auxiliary tool 5 is fitted on the rear side (building interior side 103) of the water blocking plate support pillar 1 in the hole 3 so that the wedge surface 9 and the B2 abutment wedge surface 17 abut. In this case, the fitting can be easily performed by pressing the auxiliary tool 5 pressing surface 35. In addition, at the first stage of this fitting, the tip portion 37 formed in a tapered shape is inserted into the tunnel 3 (A2 contact ridge surface 13 of the support column 1 for water blocking plate and the building interior side of the portal 3) The auxiliary tool 5 can be easily fitted in the fistula 3 by being inserted between the rib surface 9 positioned at 103) and guiding the whole.
図8に示すとおり、補助具5を竪孔3内に嵌装することで、止水板用支持柱1が建物外部側105方向に押し詰められることになるので、止水材19が押圧される。これにより、竪孔3に対する止水板用支持柱1の嵌装位置が定められて止水板用支持柱1が竪孔3内に確実に設置され、止水材19によって、建物外部側105方向に位置する竪面9とA1当接竪面11との隙間が確実に密閉されて、高い止水機能(水密性)を発揮できると共に、後述するように止水板用支持柱1に当接して止水板107を設置し、水圧によって止水板107が建物内部側103に倒れようとしたとしても、止水板用支持柱1は竪孔3内に押し詰められて設置されているため傾斜することなく、止水板107を支持できるようになる。 As shown in FIG. 8, by fitting the auxiliary tool 5 in the fistula 3, the water-stop plate support pillar 1 is squeezed toward the outside 105 of the building, so that the water-stop material 19 is pressed. The Thereby, the fitting position of the water-stop plate support pillar 1 with respect to the fistula 3 is determined, and the water-stop plate support pillar 1 is surely installed in the fistula 3. The gap between the wedge surface 9 positioned in the direction and the A1 contact wedge surface 11 is reliably sealed, and a high water blocking function (water tightness) can be exhibited, and the water blocking plate support pillar 1 is touched as described later. Even if the water stop plate 107 is installed in contact with the water stop plate 107 and the water stop plate 107 is about to fall down to the inside 103 of the building due to water pressure, the water stop plate support pillar 1 is pressed and installed in the fistula 3. Therefore, the water stop plate 107 can be supported without inclining.
上記手順の伴い、止水板用支持柱1が確実に固定され、止水板用支持柱1を介して建物開口101に止水板107を設置することができる。図9に示すとおり、建物開口101を形成する両端の開口縁111と止水板用支持柱1との間に止水板107を運搬して床面109に立設させ、止水板107の建物開口101における間口方向の端部それぞれを、開口縁111と止水板用支持柱1とに固定する。止水板107の間口方向の端部と開口縁111、あるいは止水板用支持柱1との固定には、公知の手法を用いることができ、例えば特開2017−160693号公報に示されるトグル式の金具を用いて固定すればよい。 With the above procedure, the water blocking plate support pillar 1 is securely fixed, and the water blocking plate 107 can be installed at the building opening 101 via the water blocking plate support pillar 1. As shown in FIG. 9, the water stop plate 107 is transported between the opening edges 111 at both ends forming the building opening 101 and the water stop plate support pillar 1 and is erected on the floor surface 109. Each end of the building opening 101 in the frontage direction is fixed to the opening edge 111 and the water blocking plate support pillar 1. A known method can be used to fix the end in the direction of the opening of the water blocking plate 107 and the opening edge 111 or the support post 1 for water blocking plate, and a toggle shown in, for example, JP-A-2017-160693. What is necessary is just to fix using a type | mold metal fitting.
使用する止水板107は、例えば略平行な第一の面(前方面)及び第二の面(後方面)を有し、所定の厚みを有する略矩形の板状部材であり、止水板としての機能を果たしかつ本発明の効果を損なわない範囲で種々の材料を用いて構成されたものが好ましい。樹脂製であっても金属製であってもよく、また、例えば止水板の主体部分が樹脂製で周縁に金属製の枠材を以って構成していてもよいし、少なくとも第一の面と第二の面を有し、その間を桟構造で連結した中空構造を有していてもよい。 The water blocking plate 107 used is, for example, a substantially rectangular plate-like member having a substantially parallel first surface (front surface) and a second surface (rear surface) and having a predetermined thickness. It is preferable to use various materials as long as the above functions are achieved and the effects of the present invention are not impaired. It may be made of resin or metal, and for example, the main part of the water blocking plate may be made of resin and a metal frame material may be formed on the periphery, or at least the first You may have the hollow structure which has the surface and the 2nd surface, and connected between them by the crosspiece structure.
止水板107の間口方向両端部(例えば間口方向両端部の後方面)及び止水板107の下端(床面109に当接する面)には、高さ方向及び水平方向に延びる止水パッキン(図示せず)が配設されていることが望ましい。止水パッキンは、ゴム材料、樹脂材料若しくは樹脂発泡体又は空気袋体等で構成することができ、止水板107に水圧が負荷されたときに弾性変形して水圧を受け止め、かつ止水板107と開口縁111及び床面109との間から漏水しないように密封する、いわゆるシール材あるいはパッキンとしての機能を持つ(なお、ここでは、止水板107に設けた止水材を、止水板用支持柱1の止水材と区別しやすくするために便宜上「止水パッキン」と表記しているが、この止水パッキンと止水板用支持柱1の止水材とは、本質的に相違するものではなく、同材同種のものを用いて形成してもよいことは言うまでもない。)。 On both ends of the water stop plate 107 in the front end direction (for example, the rear surface of both ends of the front end direction) and on the lower end of the water stop plate 107 (the surface in contact with the floor surface 109), a water stop packing extending in the height direction and the horizontal direction ( (Not shown) is preferably provided. The water blocking packing can be made of a rubber material, a resin material, a resin foam, an air bag body, etc., and when water pressure is applied to the water blocking plate 107, it elastically deforms to receive the water pressure, and the water blocking plate It has a function as a so-called sealing material or packing that seals so as not to leak water from between the opening edge 111 and the floor surface 109 (here, a water blocking material provided on the water blocking plate 107 For the sake of easy distinction from the water-stopping material of the support pillar 1 for plates, the “water-proof packing” is described for convenience, but the water-stopping packing and the water-stopping material of the support pillar 1 for the waterstop plate are essential. It is needless to say that the same material and the same kind may be used.
止水板用支持柱1の下部は、上述のとおり止水材19が床面109より上方に突出しているため、設置した止水材107の下端に配設された止水パッキンと当接し、止水板用支持柱1下部近傍の止水性を向上する。 The lower part of the water blocking plate supporting column 1 is in contact with the water blocking packing disposed at the lower end of the installed water blocking material 107 because the water blocking material 19 protrudes upward from the floor surface 109 as described above. The water-stopping property in the vicinity of the lower part of the support pillar 1 for the water-stopping plate is improved.
なお、止水板用支持柱1が嵌装された竪孔3の外周には、上述した蓋当接面39の存在によって形成された落ち込み部、所謂溝が存在するが、建物外部側105に位置する部分(止水材19に隣接する建物外部側105に位置する溝)には、止水板107の下端に配設された止水パッキンが上部から覆うため、水が建物外部側105からの蓋当接面39に浸入することを防止できる。本実施形態のように、止水板用支持柱1を介して、建物開口101に二枚の止水板107を設置する場合においても止水板107の止水パッキンが溝を上から覆うため、同様に止水性を担保できるが、二枚の止水板107間の隙間を詰め、蓋当接面39の建物外部側105に位置する部分全てを覆うよう設置してもよい。また、二枚の止水板107の双方が当接する端面に止水パッキンを配設すれば、より確実に上記止水を行うことができる。 In addition, although there is a so-called groove formed by the presence of the above-described lid contact surface 39 on the outer periphery of the hole 3 in which the water blocking plate support pillar 1 is fitted, Since the water stop packing disposed at the lower end of the water stop plate 107 covers the portion (the groove located on the building external side 105 adjacent to the water stop material 19) from the top, the water flows from the building external side 105. Intrusion into the lid contact surface 39 can be prevented. Even when two water stop plates 107 are installed in the building opening 101 via the water stop plate support pillar 1 as in this embodiment, the water stop packing of the water stop plate 107 covers the groove from above. Similarly, the water-stopping property can be ensured, but the gap between the two water-stopping plates 107 may be filled and the lid abutting surface 39 may be installed so as to cover all the portions located on the building exterior side 105. Moreover, if the water stop packing is provided on the end face where both of the two water stop plates 107 abut, the water stop can be performed more reliably.
6.止水板用支持柱1を用いたその他の止水板107の設置態様
本発明は、上述以外にも止水板用支持柱を用いたその他の止水板107の設置態様を取ることもできる。図10(a)及び(b)を用いて、止水板用支持柱を用いたその他の止水板107の設置態様について説明する。図10(a)及び(b)は、止水板用支持柱を用いたその他の止水板107の設置態様を示す図であって、図10(a)は、出隅状の建物開口101に対応した態様を示す平面図であり、図10(b)は、傾斜した壁面の建物開口101に対応した態様を示す平面図である。
6. The installation aspect of the other water stop board 107 using the support column 1 for water stop boards This invention can also take the installation aspect of the other water stop board 107 using the support column for water stop boards besides the above-mentioned. . The installation aspect of the other water stop board 107 using the support pillar for water stop boards is demonstrated using FIG. 10 (a) and (b). FIGS. 10 (a) and 10 (b) are diagrams showing the installation mode of the other water blocking plate 107 using the water blocking plate support column, and FIG. 10 (b) is a plan view showing an aspect corresponding to the building opening 101 of the inclined wall surface.
図10(a)に示すような出隅状の建物開口101に対応する場合、例えば双方の開口縁111の延長線上における交差点に、双方の開口縁111と略平行な面を具備する略五角形の断面形状を有した止水板用支持柱201を設置すれば、当該止水板用支持柱201を介して二枚の止水板107を建物開口101に設置して止水を行うことができる。 In the case of corresponding to the projected corner shaped building opening 101 as shown in FIG. 10A, for example, a substantially pentagon having a plane substantially parallel to both opening edges 111 at the intersection on the extension line of both opening edges 111 If the water blocking plate support column 201 having the cross sectional shape is installed, two water blocking plates 107 can be installed in the building opening 101 via the water blocking plate support column 201 to perform water blocking. .
また、図10(b)に示すような傾斜した壁面に設けられた建物開口101に対応する場合、止水板用支持柱1の止水板当接面7を傾斜した壁面と略平行となるよう設置し、当該止水板用支持柱1を介して建物開口101に止水板107を設置することで止水を行うことができる。 In addition, in the case of corresponding to the building opening 101 provided on the inclined wall surface as shown in FIG. 10B, the water stop plate abutment surface 7 of the water stop plate support column 1 is substantially parallel to the inclined wall surface. The water stop can be performed by installing the water stop plate 107 in the building opening 101 through the support pillar 1 for the water stop plate.
更に、図10(c)に示すように、止水板用支持柱1を介して一枚の止水板107を建物開口101に設置し、建物内部側103から当該止水板107の略中央を支持することで撓みを防止し、耐水圧性及び止水性を向上させてもよい。 Furthermore, as shown in FIG. 10 (c), one water blocking plate 107 is installed at the building opening 101 via the water blocking plate support pillar 1, and the substantially central portion of the water blocking plate 107 from the building interior side 103. It may be possible to prevent bending by supporting and improve water pressure resistance and water stoppage.
上述のとおり、建物開口101及び開口縁111の形状に応じて止水板用支持柱の形状や配置方法を変更すれば、建物開口101の態様に応じて幅広く対応することができる。 As described above, if the shape and the arrangement method of the water blocking plate support pillars are changed according to the shapes of the building opening 101 and the opening edge 111, it can be widely handled according to the aspect of the building opening 101.
7.その他の止水板用支持柱及び補助具
次に、図11と、図14(a)及び(b)と、を用いてその他の止水板用支持柱51について説明する。図11は、止水板用支持柱51の構造を示す斜視図である。図14(a)及び(b)は、止水板用支持柱51の変形例を示す図であって、図14(a)は、止水板当接面57にI形突起83を具備させた止水板用支持柱51の断面図であり、図14(b)は、止水板当接面57にT形突起85を具備させた止水板用支持柱51の断面図である。
7). Other Water Barrier Plate Support Columns and Auxiliary Tools Next, other water barrier plate support columns 51 will be described using FIG. 11 and FIGS. 14 (a) and 14 (b). FIG. 11 is a perspective view showing the structure of the water blocking plate support pillar 51. As shown in FIG. 14 (a) and 14 (b) are diagrams showing a modification of the water blocking plate support column 51, and FIG. 14 (a) is provided with an I-shaped projection 83 on the water blocking plate contact surface 57. FIG. 14B is a cross-sectional view of the water blocking plate support column 51 provided with a T-shaped projection 85 on the water blocking plate contact surface 57. FIG.
図11に示すとおり、C字形(略リップ溝形鋼と同様の断面形状)の断面形状を有する柱体73を用い、上端側P1に天板81及び下端側P2に底板79を別途固定して構成した止水板用支持柱51を用いることができる。これにより、A2当接竪面63を有する面が左右に分割され、略中央に縦方向に伸びるスリット82を有する。 As shown in FIG. 11, a column body 73 having a C-shaped (substantially the same cross-sectional shape as the lip groove steel) is used, and a top plate 81 is fixed to the upper end side P1 and a bottom plate 79 is separately fixed to the lower end side P2. It is possible to use the water blocking plate support pillar 51 that is configured. Thereby, the surface having the A2 contact flange surface 63 is divided into left and right, and has a slit 82 extending in the vertical direction substantially at the center.
C字形の断面形状を有する柱体73を用いれば、止水板用支持柱51を容易に軽量化できると共に、使用する補助具の厚さ寸法が比較的薄いものであっても、柱体73のスリット82に足のつま先等を挿入して補助具の押圧面を下方に向かって強く押圧することができる(換言すれば、補助具の嵌装を容易かつ確実に行うことができる。)。 If the pillar body 73 having a C-shaped cross-sectional shape is used, the water stop plate support pillar 51 can be easily reduced in weight, and the pillar body 73 can be used even if the thickness of the auxiliary tool used is relatively thin. The toe of the foot or the like can be inserted into the slit 82 to strongly press the pressing surface of the assisting tool downward (in other words, the fitting of the assisting instrument can be performed easily and reliably).
更に、止水板当接面57の略中央に、縦方向に伸びるI形突起83を配設(図14(a)参照)、又はT形突起85を配設(図14(b)参照)すれば、止水板107をより確実かつ簡便に位置決めして設置することができると共に、当該部位を止水板の固定に利用することも可能となる。即ち、開口縁111側に、床面109に対して略鉛直に伸びる溝を直接形成したり、コの字状の断面を有する鋼材等を配設すれば、上記I形突起83やT形突起85と共に止水板107を間口方向両端から支持することが可能となり、より確実な設置を行うことができる。 Furthermore, an I-shaped projection 83 extending in the longitudinal direction is disposed substantially at the center of the water blocking plate abutment surface 57 (see FIG. 14A), or a T-shaped projection 85 is disposed (see FIG. 14B). By doing so, the water stop plate 107 can be positioned and installed more reliably and easily, and the part can be used for fixing the water stop plate. That is, if a groove extending substantially vertically to the floor surface 109 is directly formed on the opening edge 111 side, or if a steel material or the like having a U-shaped cross section is disposed, the I-shaped protrusion 83 or the T-shaped protrusion 85 and the water stop plate 107 can be supported from both ends in the frontage direction, and more reliable installation can be performed.
続いて、図12(a)及び(b)と、図13(a)及び(b)と、を用いてその他の補助具について説明する。図12(a)及び(b)は、補助具55を示す図であって、図12(a)は、補助具55の構造を示す斜視図であり、図12(b)は、補助具55を用いて竪孔3に止水板用支持柱51を嵌装した状態を示す断面図である。また、図13(a)及び(b)は、補助具255を示す図であって、図13(a)は、補助具255の構造を示す斜視図であり、図13(b)は、補助具255を用いて竪孔3に止水板用支持柱51を嵌装した状態を示す断面図である。 Next, other assisting devices will be described with reference to FIGS. 12 (a) and 12 (b) and FIGS. 13 (a) and 13 (b). 12 (a) and 12 (b) show the aid 55, and FIG. 12 (a) is a perspective view showing the structure of the aid 55, and FIG. 12 (b) shows the aid 55. It is sectional drawing which shows the state which fitted the water-stop plate support pillar 51 in the fistula 3 using this. 13 (a) and 13 (b) show the aid 255, and FIG. 13 (a) is a perspective view showing the structure of the aid 255, and FIG. 13 (b) shows the aid FIG. 6 is a cross-sectional view showing a state in which a water stop plate support column 51 is fitted into the fistula 3 using a tool 255.
図12(a)に示すような、補助具55本体の前後面から前方(建物外部側105)及び/又は後方(建物内部側103)に突出ないし膨出して形成した面積の広い押圧面71(図12では前方及び後方に膨出するように押圧面71を形成している。)を具備させた補助具55を構成すれば、竪孔3への嵌装時において、補助具55に対してより確実に押圧力を加えることができる。また、図12(b)に示すとおり、上述した止水板用支持柱51と合わせれば、押圧面71がA2当接竪面63に干渉することなく、止水板用支持柱51に沿わせて竪孔3に嵌装することができる。 As shown in FIG. 12 (a), a pressing surface 71 with a large area formed by projecting or bulging forward (building exterior side 105) and / or aft (building interior side 103) from the front and rear surfaces of the auxiliary tool 55 main body In FIG. 12, the pressing surface 71 is formed so as to bulge forward and backward). A pressing force can be applied more reliably. Further, as shown in FIG. 12 (b), the pressing surface 71 does not interfere with the A2 contact wedge surface 63 when it is aligned with the above-described water blocking plate support column 51, and is made to follow the water blocking plate support column 51. Can be fitted into the fistula 3.
また、図13(a)に示すような、B1当接竪面265の略中央で縦方向に伸びるT形突起272を具備した補助具255を構成すれば、図13(b)に示すように上述した止水板用支持柱51の双方のA2当接竪面63を溝274と嵌合することで、補助具255がスリット82に沿って上下方向にスライド可能となり、止水板用支持柱51と補助具255とを一体的に構成することができる。これにより、例えば補助具255の紛失や補助具255の嵌装忘れ等を解消し、止水板107の設置時に迅速に止水板用支持柱51の設置作業を行うことができる。 Further, as shown in FIG. 13 (b), an auxiliary tool 255 having a T-shaped projection 272 extending in the longitudinal direction substantially at the center of the B1 contact wedge surface 265 as shown in FIG. 13 (a) is constructed. By fitting the A2 contact wedge surfaces 63 of both the water blocking plate support pillars 51 with the grooves 274, the auxiliary tool 255 can slide vertically along the slits 82, and the water blocking plate support pillars 51 and the auxiliary tool 255 can be integrally formed. Thereby, for example, the loss of the auxiliary tool 255 and the forgetting of fitting of the auxiliary tool 255 can be eliminated, and the installation work of the water blocking plate support pillar 51 can be performed quickly when the water blocking plate 107 is installed.
以上、本実施形態における止水板用支持柱の設置方法の代表的な実施形態について図面を参照しつつ説明してきたが、本発明は、これらの実施形態に限定されるものではなく、特許請求の範囲の記載の精神及び教示を逸脱しない範囲でその他の変形例や改良例が存在し、これらは全て本発明の技術的範囲に含まれる。 As mentioned above, although the typical embodiment of the installation method of the support pillar for water stop boards in this embodiment was explained referring to drawings, the present invention is not limited to these embodiments, and claims Other variations and modifications exist within the scope of the present invention without departing from the spirit and the teaching of the scope of the present invention, all of which are included in the technical scope of the present invention.
例えば、上記した蓋当接面39を構成せず、例えば一部が直接竪孔3の底面43に当接支持して嵌合可能な蓋を形成して用いてもよい。またあるいは、図15(a)及び(b)に示すようなその他の蓋当接面239を構成してもよい。図15(a)及び(b)は、その他の蓋当接面239の構造を示す図であって、図15(a)は、蓋当接面239を具備する竪孔203を示す平面図であり、図15(b)は、図15(a)の矢視Bを示す断面図である。 For example, the lid contact surface 39 described above may not be configured, and for example, a lid may be used which is partially supported directly on the bottom surface 43 of the fistula 3 to be fitted. Alternatively, another lid contact surface 239 as shown in FIGS. 15A and 15B may be configured. FIGS. 15A and 15B are views showing the structure of the other lid abutting surface 239, and FIG. 15A is a plan view showing the hole 203 having the lid abutting surface 239. FIG. FIG. 15 (b) is a cross-sectional view showing the arrow B in FIG. 15 (a).
蓋当接面239は、建物開口101の間口方向に対向する二つの竪面209と、建物外部側105に対向する竪面209と、の3つの面の上端部を折り曲げて拡幅することで構成する一方、建物内部側103に対向する竪面209(即ち、竪孔の建物外部側105寄りに形成された竪面)は床面109まで折り曲げずに、竪孔上端縁まで略鉛直に形成されているため、止水板用支持柱1を嵌装した際に、建物外部側105に位置する部分には溝が形成されない。即ち、止水板107を設置する際に、止水板107が接地する床面に溝がないため、当該部分での止水性をより向上できる。 The lid contact surface 239 is configured by bending and widening the upper end portions of the three surfaces of the two ridge surfaces 209 facing the opening direction of the building opening 101 and the ridge surface 209 facing the building exterior side 105. On the other hand, the ridge 209 facing the building interior side 103 (that is, the ridge formed near the building exterior side 105) is not bent to the floor 109 but is formed substantially vertically to the upper edge of the ridge. Therefore, when the water stop plate support pillar 1 is fitted, no groove is formed in the portion located on the building exterior side 105. That is, when the water stop plate 107 is installed, there is no groove on the floor surface to which the water stop plate 107 contacts, so that the water stop at that portion can be further improved.
このような蓋当接面239を具備した竪孔203を構成すれば、蓋41を嵌合させて竪孔203を塞ぎつつ床面109を平担に維持することができると共に、簡便に止水性を担保することができる。より具体的には、止水板用支持柱1を介して、建物開口101に二枚の止水板107を設置する際、上述の実施形態では双方の止水板107間の隙間を詰めて止水板107の下端に配設した止水パッキンで蓋当接面39の建物外部側105に位置する部分の溝全てを覆うよう設置して止水性を担保しなくとも、その他の蓋当接面239を具備した竪孔203であれば、上述のとおり建物外部側105に位置する部分に溝が形成されないため、二枚の止水板107間の隙間を厳密に詰めて配設しなくても水が浸入する隙間が形成されないため、止水板107の配設方法を簡便化しつつ止水性を担保することができる。 If the fistula 203 having such a lid abutting surface 239 is configured, the floor surface 109 can be maintained flat while the lid 41 is fitted and the fistula 203 is closed, and a water-stopping function can be simply achieved. Can be secured. More specifically, when the two water stop plates 107 are installed in the building opening 101 via the water stop plate support pillars 1, the gap between the two water stop plates 107 is reduced in the above-described embodiment. It is installed so as to cover all the grooves of the portion located on the building exterior side 105 of the lid contact surface 39 by the water blocking packing disposed at the lower end of the water blocking plate 107, and the other lid contact is not secured. In the case of the fistula 203 having the surface 239, since the groove is not formed in the portion located on the outside 105 side of the building as described above, the gap between the two water stop plates 107 must be closely packed and disposed. In addition, since a gap for water to enter is not formed, water stoppage can be ensured while simplifying the arrangement method of the waterstop plate 107.
本実施形態における止水板は、高い圧性等を備えながら、簡便容易に止水板用支持柱を設置可能とする止水板用支持柱の設置構造である。 The water blocking plate in the present embodiment is an installation structure of the water blocking plate support column which enables the water blocking plate support column to be simply and easily installed while having high pressure resistance and the like.
