Description
本発明は、型枠に関し、特にコンクリート構造物を建設する際に、コンクリートを打設する空間を構成するための型枠に関する。 TECHNICAL FIELD The present invention relates to a formwork, and more particularly to a formwork for constructing a space in which concrete is poured when constructing a concrete structure.
従来からコンクリート構造物の建設現場では、ベニヤ等の堰板の裏面を桟材で補強して型枠を作成し、一対の型枠の間にコンクリートを流し込んで打設していた。しかし、コンクリートが硬化した後に型枠を外すまで、コンクリートに空隙やひび割れ等の不具合が生じていないかを確認できないという問題があった。そこで、堰板を透明なプラスチック板で構成して、コンクリートの充填時から目視で施工状況を確認することができる型枠も提案されている（特許文献１等を参照）。 Conventionally, at the construction site of a concrete structure, the back surface of a barrier plate such as veneer is reinforced with crosspieces to form a formwork, and concrete is poured and placed between a pair of formwork forms. However, there is a problem that it is not possible to check whether defects such as voids or cracks have occurred in the concrete until the formwork is removed after the concrete has hardened. In view of this, there has been proposed a formwork in which the barrier plate is made of a transparent plastic plate so that the state of construction can be visually checked from the time the concrete is filled (see Patent Document 1, etc.).
しかし特許文献１の型枠では、様々な施工現場に対応させるためには、様々なサイズの堰板を各種取り揃えて運搬する必要があった。また、堰板がプラスチック製であるため、釘打ちでの桟材の固定ができず、現場での作業負担が大きくなるという問題があった。特許文献１では金属製の桟材を用いることも記載されているが、桟材の重量が増加して運搬時や作業時の効率が低下するという問題もあった。 However, with the formwork of Patent Literature 1, it was necessary to prepare and transport various types of barrier plates of various sizes in order to adapt to various construction sites. In addition, since the dam plate is made of plastic, the crosspiece cannot be fixed by nailing, and there is a problem that the work burden on the site increases. Patent document 1 also describes the use of metal crosspieces, but there is also the problem that the weight of the crosspieces increases, reducing the efficiency during transportation and work.
そこで本発明は、上記従来の問題点に鑑みなされたものであり、コンクリート打設の施工状況を目視で確認することが可能であり、かつ施工現場での作業負担を軽減することが可能な型枠を提供することを目的とする。 Therefore, the present invention has been made in view of the conventional problems described above, and it is an object of the present invention to provide a formwork that enables visual confirmation of the construction status of concrete placement and reduces the work load at the construction site.
上記課題を解決するために、本発明の型枠は、少なくとも一部に可視光を透過する透過領域を有する堰板と、前記堰板の長手方向に沿って前記堰板の裏面側に立設された複数の桟取付部を有し、前記桟取付部は、前記堰板と一体に形成されており、前記桟取付部は前記長手方向に沿って複数に分離され、前記桟取付部の間には幅方向に沿って前記堰板の裏面側が露出した領域が存在することを特徴とする。
また、上記課題を解決するために、本発明の型枠は、少なくとも一部に可視光を透過する透過領域を有する堰板と、前記堰板の長手方向に沿って前記堰板の裏面側に立設された複数の桟取付部を有し、前記桟取付部は、前記長手方向に直交する幅方向に所定間隔で設けられた一対の挟持片を備え、前記挟持片の互いに対向する面には、前記挟持片と一体に形成された摺動規制突起が設けられていることを特徴とする。
In order to solve the above-mentioned problems, the formwork of the present invention is characterized in that it has a barrier plate having a transmission region that transmits visible light in at least a part thereof, and a plurality of crosspiece attachment portions that stand upright on the back side of the barrier plate along the longitudinal direction of the barrier plate, wherein the crosspiece attachment portion is formed integrally with the barrier plate, the crosspiece attachment portion is divided into a plurality of parts along the longitudinal direction, and a region where the back side of the barrier plate is exposed exists along the width direction between the crosspiece attachment portions.
In addition, in order to solve the above issues, the formwork of the present invention has at least a weir plate with a transparent region that transmits visible light at least, and a plurality of pier attached to the back of the weir board along the long direction of the weir board, and the pier mounting part is a predetermined intercourse in the long orth -direction. It is characterized by a pair of padded fragments provided, and a sliding regulation protrusion formed together with the padded fragments are provided on the face facing each other.
このような本発明の型枠では、堰板の裏面側に複数の桟取付部が立設されており、堰板に透過領域を有するため、コンクリート打設の施工状況を目視で確認することが可能であり、かつ施工現場での作業負担を軽減することが可能となる。 In such a formwork of the present invention, a plurality of crosspiece mounting portions are erected on the back side of the dam plate, and the dam plate has a transmission region, so it is possible to visually confirm the construction status of concrete placement, and it is possible to reduce the work load at the construction site.
本発明では、コンクリート打設の施工状況を目視で確認することが可能であり、かつ施工現場での作業負担を軽減することが可能な型枠を提供することができる。 ADVANTAGE OF THE INVENTION In this invention, it is possible to visually confirm the construction condition of concrete placing, and can provide the formwork which can reduce the work burden in a construction site.
（第１実施形態）
以下、本発明の実施形態について、図面を参照して詳細に説明する。各図面に示される同一または同等の構成要素、部材、処理には、同一の符号を付すものとし、適宜重複した説明は省略する。本実施形態では、型枠１００を用いたコンクリート打設方法について説明するが、本発明の型枠１００はコンクリート打設に限定されず、他の建築材料を用いた工法にも適用できる。図１は、本実施形態に係る型枠１００を用いたコンクリート打設の施工状況を示す模式図である。図２は、型枠１００の構造を示す図であり、図２（ａ）は表面１０ａ、図２（ｂ）は縦断面、図２（ｃ）は裏面１０ｂ、図２（ｄ）は横断面を示している。
(First embodiment)
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same or equivalent constituent elements, members, and processes shown in each drawing are denoted by the same reference numerals, and duplication of description will be omitted as appropriate. In this embodiment, a method of placing concrete using the formwork 100 will be described, but the formwork 100 of the present invention is not limited to placing concrete, and can be applied to construction methods using other building materials. FIG. 1 is a schematic diagram showing the state of concrete placement using the formwork 100 according to the present embodiment. 2A and 2B show the structure of the formwork 100. FIG. 2A shows the front surface 10a, FIG. 2B shows the longitudinal section, FIG. 2C shows the rear surface 10b, and FIG. 2D shows the cross section.
図１に示したように、型枠１００は、堰板１０の裏面１０ｂに複数の桟取付部１１が設けられている。また、型枠１００の裏面１０ｂ側には複数の桟材２０が桟取付部１１に取り付けられており、桟材２０で堰板１０と延長板３０が保持されている。また、一対の型枠１００が所定距離を隔てて対向して配置されており、堰板１０の間に構成された空間に充填材料４０が打設される。図１では堰板１０の高さ方向における途中まで充填材料４０が注入された状態を示しているが、充填材料４０の注入を継続して、延長板３０の高さまで充填材料４０を到達させることができる。 As shown in FIG. 1, the formwork 100 is provided with a plurality of crosspiece mounting portions 11 on the rear surface 10b of the barrier plate 10. As shown in FIG. A plurality of crosspieces 20 are attached to the crosspiece mounting portion 11 on the side of the rear surface 10b of the mold 100, and the crosspieces 20 hold the barrier plate 10 and the extension plate 30. As shown in FIG. Also, a pair of forms 100 are arranged facing each other with a predetermined distance therebetween, and a filling material 40 is placed in the space formed between the barrier plates 10 . Although FIG. 1 shows a state in which the filling material 40 is injected halfway in the height direction of the barrier plate 10, the injection of the filling material 40 can be continued to reach the height of the extension plate 30.
堰板１０は、表面１０ａと裏面１０ｂを有する略平板状の部材である。堰板１０の表面１０ａ側は充填材料４０が接触する面であり、裏面１０ｂ側は桟材２０が取り付けられて補強される面である。また、堰板１０の裏面１０ｂ側には、複数の桟取付部１１が立設されている。また、堰板１０の上端および下端には複数の固定孔１２，１３が設けられている。 The barrier plate 10 is a substantially flat member having a front surface 10a and a back surface 10b. The front surface 10a side of the barrier plate 10 is the surface with which the filling material 40 contacts, and the rear surface 10b side is the surface to which the crosspiece 20 is attached and reinforced. A plurality of crosspiece mounting portions 11 are erected on the rear surface 10b side of the barrier plate 10. As shown in FIG. A plurality of fixing holes 12 and 13 are provided at the upper and lower ends of the barrier plate 10 .
堰板１０は可視光を透過する材料で構成された透過領域を有している。本実施形態では、堰板１０の全体を透過領域とした例を示している。透過領域を構成する材料は限定されないが、例えばＰＥＴ（Ｐｏｌｙｅｔｈｙｌｅｎｅｔｅｒｅｐｈｔｈａｌａｔｅ）樹脂や、アクリル樹脂、エポキシ樹脂、メタクリル樹脂、ポリカーボネート、ＡＢＳ樹脂、ＰＥ樹脂、ＰＰ樹脂、ＰＶＣ樹脂等を用いることができる。特に、再生ＰＥＴ樹脂を用いることで省資源化を図るとともに、堰板１０のリサイクル化を図ることが好ましい。堰板１０に透過領域が設けられていることで、図１に示したように、充填材料４０を注入している段階から、充填される充填材料４０の施工状況を外部から視認することができる。堰板１０のサイズは限定されないが、例えば幅６００ｍｍ、長さ１８００ｍｍ、厚さ１２ｍｍ等のベニヤ板と同程度とすることができる。 The barrier plate 10 has a transmission region made of a material that transmits visible light. This embodiment shows an example in which the entire barrier plate 10 is used as the transmission region. Although the material forming the transmission region is not limited, for example, PET (Polyethyleneterephthalate) resin, acrylic resin, epoxy resin, methacrylic resin, polycarbonate, ABS resin, PE resin, PP resin, PVC resin, etc. can be used. In particular, it is preferable to use recycled PET resin to save resources and to recycle the barrier plate 10 . Since the barrier plate 10 is provided with the transmission region, as shown in FIG. 1, the construction status of the filling material 40 to be filled can be visually recognized from the outside from the stage of injecting the filling material 40. Although the size of the barrier plate 10 is not limited, it can be approximately the same size as a veneer plate, such as 600 mm wide, 1800 mm long, and 12 mm thick.
桟取付部１１は、堰板１０と一体に形成され、裏面１０ｂから離れる方向に立設された、桟材２０を取り付けるための部分である。本実施形態では、桟取付部１１として、略板状の２枚の挟持片を一対としたものを示しているが、桟取付部１１の具体的な構造は限定されない。図１，２に示したように、本実施形態では桟取付部１１は堰板１０の長手方向に沿って複数分離して配列されるとともに、長手方向と直交する幅方向にも複数分離して配列されており、全体としてマトリクス状に配置されている。図１では、堰板１０を地面に対して鉛直方向に設けているため、桟材２０を鉛直方向に沿って取り付けた例を示しているが、所定角度で堰板１０を傾斜させる場合等には、長手方向に分離して設けられた桟取付部１１の間にパイプ等の保持材を配置することもできる。 The crosspiece attachment portion 11 is a portion for attaching a crosspiece member 20 which is formed integrally with the barrier plate 10 and erected in a direction away from the back surface 10b. In the present embodiment, a pair of two substantially plate-shaped clamping pieces is shown as the crosspiece mounting portion 11, but the specific structure of the crosspiece mounting portion 11 is not limited. As shown in FIGS. 1 and 2, in the present embodiment, a plurality of beam attachment portions 11 are arranged along the longitudinal direction of the sheathing plate 10, and are also arranged separately in a width direction perpendicular to the longitudinal direction, and are arranged in a matrix as a whole. In FIG. 1, since the barrier plate 10 is provided in the vertical direction with respect to the ground, an example in which the crosspiece member 20 is attached along the vertical direction is shown. However, when the barrier plate 10 is inclined at a predetermined angle, etc., a holding member such as a pipe can be arranged between the crosspiece attachment portions 11 provided separately in the longitudinal direction.
図２に示すように、桟取付部１１には固定孔１１ａが設けられている。固定孔１１ａには後述するように締結部材５０が挿入されて、桟材２０を桟取付部１１に固定することが可能となっている。また、桟取付部１１は一対の挟持片が対向して配置されており、挟持片の間には所定間隔ｄの桟挿入部１１ｂが構成されている。桟取付部１１のサイズは限定されないが、例えば長さ１５７ｍｍ、高さ４０ｍｍ、厚さ２ｍｍの挟持片を所定間隔ｄ＝２５ｍｍで対向させたものを用いることができる。また桟取付部１１の間隔は、一例として長さ方向に１００ｍｍ、幅方向に１５６ｍｍ等とすることができる。 As shown in FIG. 2, the crosspiece mounting portion 11 is provided with a fixing hole 11a. A fastening member 50 is inserted into the fixing hole 11 a to fix the crosspiece member 20 to the crosspiece mounting portion 11 as will be described later. In addition, the crosspiece mounting portion 11 is provided with a pair of clamping pieces facing each other, and a crosspiece insertion portion 11b is formed between the clamping pieces at a predetermined interval d. Although the size of the crosspiece mounting portion 11 is not limited, for example, clamping pieces having a length of 157 mm, a height of 40 mm, and a thickness of 2 mm are opposed to each other with a predetermined interval d=25 mm. Further, the interval between the crosspiece mounting portions 11 can be, for example, 100 mm in the length direction and 156 mm in the width direction.
固定孔１２，１３は、堰板１０の上端および下端に設けられた貫通孔であり、堰板１０の表面１０ａ側から裏面１０ｂ側にネジや釘等の締結部材を挿入可能とする部分である。堰板１０の裏面１０ｂ側において下端辺１０ｃおよび上端辺１０ｄに幅方向に枠材を設けて補強する場合には、固定孔１２，１３にネジや釘等の締結部材を挿入して枠材を固定することができる。ここでは固定孔１２，１３を設けた例を示したが、固定孔１２，１３を省略した構成としてもよい。 The fixing holes 12 and 13 are through holes provided at the upper and lower ends of the shuttering plate 10, and are portions through which fastening members such as screws and nails can be inserted from the front surface 10a side of the shuttering plate 10 to the rear surface 10b side. When reinforcing the lower side 10c and the upper side 10d of the back surface 10b of the barrier plate 10 by providing frame members in the width direction, fastening members such as screws and nails can be inserted into the fixing holes 12 and 13 to fix the frame members. Although an example in which the fixing holes 12 and 13 are provided is shown here, the fixing holes 12 and 13 may be omitted.
桟材２０は、桟取付部１１に取り付けられて、堰板１０の補強を行う部材である。桟材２０の厚みは、桟挿入部１１ｂに桟材２０を挿入できるサイズとし、長さは堰板１０の長さ以上のものを用いる。堰板１０の長さよりも長い桟材２０を用いることで、堰板１０の上端または下端よりも突出した部分に延長板３０を固定して、堰板１０の長さ以上の施工高さにも対応させることができる。桟材２０の具体的な構成は限定されないが、幅４８ｍｍ厚み２４ｍｍ等に規格化された木材である桟木を用いることができる。 The crosspiece 20 is a member that is attached to the crosspiece mounting portion 11 and reinforces the barrier plate 10 . The thickness of the crosspiece 20 is such that the crosspiece 20 can be inserted into the crosspiece insertion portion 11b, and the length of the crosspiece 20 is equal to or greater than the length of the barrier plate 10.例文帳に追加By using a crosspiece 20 longer than the length of the dam plate 10, the extension plate 30 is fixed to a part protruding from the upper end or the lower end of the dam plate 10, and construction height equal to or greater than the length of the dam plate 10 can be accommodated. Although the specific configuration of the crosspiece 20 is not limited, crosspieces that are standardized wood having a width of 48 mm and a thickness of 24 mm can be used.
延長板３０は、堰板１０の上端または下端に隣接して配置され、裏面１０ｂに桟材２０が取り付けられた板状の部材である。延長板３０の表面は、堰板１０の表面１０ａと略面一とされており、堰板１０および延長板３０の組み合わせで型枠１００が構成される。図１では延長板３０を用いる例を示しているが、堰板１０のみで施工高さを確保できる場合には、延長板３０を省略するとしてもよい。延長板３０の構成は限定されず、可視光を透過する樹脂製の板やベニヤ板等を用いることができる。延長板３０を桟材２０に固定することで、作業現場で延長板３０を取り付けるだけで堰板１０のサイズ不足を補うことができる。これにより、堰板１０として複数のサイズを確保して作業現場まで運搬する必要が無くなり、規格化されたサイズの堰板１０だけで様々な施工に対応することが可能となる。 The extension plate 30 is a plate-shaped member arranged adjacent to the upper end or the lower end of the barrier plate 10 and having the crosspiece 20 attached to the rear surface 10b. The surface of the extension plate 30 is substantially flush with the surface 10 a of the barrier plate 10 , and the combination of the barrier plate 10 and the extension plate 30 constitutes the formwork 100 . Although FIG. 1 shows an example using the extension plate 30, the extension plate 30 may be omitted if the construction height can be secured only with the barrier plate 10. FIG. The configuration of the extension plate 30 is not limited, and a resin plate, plywood, or the like that transmits visible light can be used. By fixing the extension plate 30 to the crosspiece 20, the shortage of the size of the barrier plate 10 can be compensated by simply attaching the extension plate 30 at the work site. As a result, it is no longer necessary to secure a plurality of sizes of the barrier plate 10 and transport them to the work site, and it is possible to deal with various construction works only with the standardized size of the barrier plate 10 .
充填材料４０は、施工時に流動性を有して型枠１００の間に充填され、時間経過とともに硬化する材料であり、公知のコンクリート材料を用いることができる。充填材料４０の材料は限定されないが、堰板１０および延長板３０の表面と接触した状態で硬化するため、硬化後に良好に剥離できるように堰板１０および延長板３０を構成する材料を選択することが好ましい。 The filling material 40 is a material that has fluidity during construction, is filled between the forms 100, and hardens over time, and a known concrete material can be used. The material of the filling material 40 is not limited, but since it hardens in contact with the surfaces of the barrier plate 10 and the extension plate 30, it is preferable to select a material that constitutes the barrier plate 10 and the extension plate 30 so that it can be peeled off well after curing.
図３は、桟取付部１１への桟材２０の取り付けを示す拡大斜視図である。桟取付部１１の挟持片には、互いに対向する面に摺動規制突起１１ｃが設けられている。摺動規制突起１１ｃは、桟挿入部１１ｂ内に突出して設けられた突起であり、桟材２０が桟挿入部１１ｂに挿入された状態において、桟材２０の長手方向への移動を規制する。図３に示した例では、摺動規制突起１１ｃとして堰板１０の裏面１０ｂから離間する方向に延伸して形成されたライン形状の突起を示しているが、摺動規制突起１１ｃの形状は限定されず、ドット形状や格子形状などを用いてもよい。摺動規制突起１１ｃのサイズは限定されないが、桟材２０の長手方向への移動を効果的に規制するためには、数ｍｍ程度（一例として２ｍｍ）突出させることが好ましい。図３では摺動規制突起１１ｃを一つの挟持片に三つ設けた例を示したが、個数や位置は限定されず適宜変更可能である。 FIG. 3 is an enlarged perspective view showing how the crosspiece 20 is attached to the crosspiece mounting portion 11. As shown in FIG. The clamping pieces of the crosspiece mounting portion 11 are provided with sliding restricting projections 11c on the surfaces facing each other. The sliding restricting protrusion 11c is a protrusion protruding into the crosspiece insertion portion 11b, and restricts the movement of the crosspiece 20 in the longitudinal direction when the crosspiece 20 is inserted into the crosspiece insertion portion 11b. In the example shown in FIG. 3, line-shaped protrusions formed by extending in a direction away from the back surface 10b of the barrier plate 10 are shown as the sliding restricting protrusions 11c, but the shape of the sliding restricting protrusions 11c is not limited, and a dot shape, a lattice shape, or the like may be used. Although the size of the slide restricting protrusion 11c is not limited, it is preferable to protrude by about several millimeters (eg, 2 mm) in order to effectively restrict the movement of the crosspiece 20 in the longitudinal direction. Although FIG. 3 shows an example in which three slide restricting projections 11c are provided on one clamping piece, the number and positions thereof are not limited and can be changed as appropriate.
図３に示したように、本発明の型枠１００では、桟材２０を桟挿入部１１ｂに挿入して、一対の挟持片で桟材２０を挟持し、固定孔１１ａにネジ等の締結部材５０を挿入して、桟取付部１１に桟材２０を取り付けて固定する。ここで、挟持片の間隔ｄは桟材２０の厚みと略同程度であり、摺動規制突起１１ｃが桟挿入部１１ｂ内に突出しているため、桟材２０を桟挿入部１１ｂに挿入する際には、摺動規制突起１１ｃが桟材２０に食い込み、長手方向への移動が規制される。 As shown in FIG. 3, in the formwork 100 of the present invention, the crosspiece 20 is inserted into the crosspiece insertion portion 11b, the crosspiece 20 is sandwiched between a pair of clamping pieces, a fastening member 50 such as a screw is inserted into the fixing hole 11a, and the crosspiece 20 is attached and fixed to the crosspiece mounting portion 11. Here, the interval d between the clamping pieces is approximately the same as the thickness of the crosspiece 20, and the sliding restricting projection 11c protrudes into the crosspiece insertion portion 11b. Therefore, when the crosspiece 20 is inserted into the crosspiece inserting portion 11b, the sliding restricting projection 11c bites into the crosspiece 20 to restrict movement in the longitudinal direction.
上述したように、本実施形態の型枠１００では、少なくとも一部に可視光を透過する透過領域を有する堰板１０と、堰板１０の長手方向に沿って堰板１０の裏面１０ｂ側に立設された複数の桟取付部１１を有する。これにより、コンクリート打設の施工状況を目視で確認することが可能であり、かつ施工現場での作業負担を軽減することが可能となる。 As described above, the formwork 100 of the present embodiment has the dam plate 10 having at least a portion of the transmission region that transmits visible light, and a plurality of crosspiece mounting portions 11 erected on the back surface 10b side of the dam plate 10 along the longitudinal direction of the dam plate 10. As a result, it is possible to visually confirm the construction status of concrete placement, and it is possible to reduce the work load at the construction site.
また桟取付部１１は、長手方向に直交する幅方向に所定間隔で設けられた一対の挟持片を備え、挟持片の互いに対向する面には、摺動規制突起１１ｃが設けられている。これにより、桟材２０の長手方向への移動が摺動規制突起１１ｃによって規制され、桟材２０の抜けや位置ずれを抑制し、桟取付部１１への固定作業を容易に行うことができる。 Further, the crosspiece mounting portion 11 includes a pair of clamping pieces provided at a predetermined interval in the width direction orthogonal to the longitudinal direction, and sliding restricting projections 11c are provided on the mutually facing surfaces of the clamping pieces. As a result, the movement of the crosspiece 20 in the longitudinal direction is restricted by the sliding restricting projections 11c, so that the crosspiece 20 is prevented from slipping off or dislocated, and the fixing work to the crosspiece mounting portion 11 can be easily performed.
また桟取付部１１は、長手方向に直交する幅方向および長手方向に沿ってマトリクス状に複数分離して配置されている。これにより、複数の桟材２０を取り付けて堰板１０の補強を行うことが容易となる。また、桟取付部１１が長手方向にも分離されているため、桟取付部１１が無い領域には幅方向に沿ったパイプ等を配置して、傾斜面や水平面への施工も可能となる。 In addition, the crosspiece mounting portions 11 are arranged in a matrix form along the width direction perpendicular to the longitudinal direction and the longitudinal direction. This makes it easy to reinforce the barrier plate 10 by attaching a plurality of crosspieces 20 . In addition, since the crosspiece mounting portions 11 are also separated in the longitudinal direction, a pipe or the like along the width direction can be arranged in the region where the crosspiece mounting portions 11 are absent, making it possible to perform construction on an inclined surface or a horizontal surface.
（第２実施形態）
次に、本発明の第２実施形態について説明する。第１実施形態と重複する内容は説明を省略する。第１実施形態では、堰板１０の全面を可視光を透過する透過領域とした例を示したが、堰板１０の少なくとも一部において可視光を透過する透過領域を備えていればよい。一例としては、堰板１０の幅方向の一部が可視光を透過する樹脂材料で構成された透過領域であり、透過領域以外の部分は光が透過しない材料で構成されるとしてもよい。また、矩形状の堰板１０における対角線状に透過領域を設けるとしてもよい。
(Second embodiment)
Next, a second embodiment of the invention will be described. The description of the content that overlaps with the first embodiment is omitted. In the first embodiment, an example in which the entire surface of the barrier plate 10 is a transmission region for transmitting visible light has been described, but at least a part of the barrier plate 10 may be provided with a transmission region for transmitting visible light. As an example, a part of the barrier plate 10 in the width direction may be a transmissive region made of a resin material that transmits visible light, and the other portions may be made of a material that does not transmit light. Alternatively, transmission areas may be provided diagonally in the rectangular barrier plate 10 .
（第３実施形態）
次に、本発明の第３実施形態について説明する。第１実施形態と重複する内容は説明を省略する。第１実施形態では、桟取付部１１を堰板１０と一体に成型した例を示したが、堰板１０と桟取付部１１を別体で構成して、堰板１０の裏面１０ｂに桟取付部１１を固定するとしてもよい。一例としては、桟取付部１１を金属板で形成し、接着剤や締結部材を用いて堰板１０の裏面１０ｂ側に固定する構造が挙げられる。また、桟取付部１１として一対の挟持片を用いた例を示したが、片側の挟持片が桟材２０の左右において交互に（千鳥状に）配置するとしてもよい。また、片側の挟持片のみで桟取付部１１を構成し、締結部材５０での締結力によって桟取付部１１に桟材２０を固定するとしてもよい。
(Third Embodiment)
Next, a third embodiment of the invention will be described. The description of the content that overlaps with the first embodiment is omitted. In the first embodiment, an example in which the rail mounting portion 11 is molded integrally with the barrier plate 10 is shown, but the barrier plate 10 and the rail mounting portion 11 may be configured separately, and the rail mounting portion 11 may be fixed to the back surface 10b of the barrier plate 10. As an example, there is a structure in which the crosspiece mounting portion 11 is formed of a metal plate and fixed to the rear surface 10b side of the barrier plate 10 using an adhesive or a fastening member. Moreover, although an example of using a pair of clamping pieces as the crosspiece mounting portion 11 has been shown, the clamping pieces on one side may be arranged alternately (in a staggered manner) on the left and right sides of the crosspiece 20 . Alternatively, the crosspiece mounting portion 11 may be configured by only one clamping piece, and the crosspiece member 20 may be fixed to the crosspiece mounting portion 11 by the fastening force of the fastening member 50 .
本発明は上述した各実施形態に限定されるものではなく、請求項に示した範囲で種々の変更が可能であり、異なる実施形態にそれぞれ開示された技術的手段を適宜組み合わせて得られる実施形態についても本発明の技術的範囲に含まれる。 The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments are also included in the technical scope of the present invention.
