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。 The present invention relates to formwork, and in particular to formwork for forming a space into 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）。 Traditionally, at construction sites of concrete structures, a formwork would be created by reinforcing the backside of a barrier such as plywood with crosspieces, and concrete would be poured between the pair of forms. However, there was a problem in that it was not possible to check whether the concrete had any defects such as voids or cracks until the formwork was removed after the concrete had hardened. As a result, a formwork has been proposed in which the barrier is made of a transparent plastic plate, allowing the construction status to 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 in Patent Document 1, it was necessary to stock and transport a variety of different sizes of dam panels in order to accommodate a variety of construction sites. In addition, because the dam panels are made of plastic, the crosspieces could not be fixed by nailing, which increased the workload on site. Patent Document 1 also describes the use of metal crosspieces, but this increases the weight of the crosspieces, which causes problems with reduced 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。 The present invention has been developed in consideration of the above-mentioned problems with the conventional method, and aims to provide a formwork that allows the construction status of concrete pouring to be visually confirmed and reduces the workload 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することを特徴とする。 To solve the above problems, the formwork of the present invention is characterized by having a dam plate having at least a partially transparent area that transmits visible light, and a plurality of batten attachment parts erected on the back side of the dam plate along the longitudinal direction of the dam plate.
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 the formwork of the present invention, multiple batten mounting sections are erected on the back side of the dam plate, and the dam plate has a transparent area, making it possible to visually check the construction status of concrete pouring and reducing the workload 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。 The present invention provides a formwork that allows the construction status of concrete pouring to be visually confirmed and reduces the workload at the 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
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The same or equivalent components, members, and processes shown in each drawing will be given the same reference numerals, and duplicated descriptions will be omitted as appropriate. In this embodiment, a concrete pouring method using a formwork 100 will be described, but the formwork 100 of the present invention is not limited to concrete pouring, and can be applied to construction methods using other building materials. FIG. 1 is a schematic diagram showing a construction situation of concrete pouring using the formwork 100 according to this embodiment. FIG. 2 is a diagram showing the structure of the formwork 100, where FIG. 2(a) shows the front surface 10a, FIG. 2(b) shows the vertical cross section, FIG. 2(c) shows the back surface 10b, and FIG. 2(d) shows the horizontal 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 has multiple batten attachment sections 11 on the back surface 10b of the sheathing board 10. Additionally, multiple batten members 20 are attached to the batten attachment sections 11 on the back surface 10b side of the formwork 100, and the sheathing board 10 and the extension board 30 are held by the batten members 20. Additionally, a pair of formworks 100 are arranged facing each other at a predetermined distance, and filling material 40 is poured into the space formed between the sheathing boards 10. FIG. 1 shows a state in which the filling material 40 has been injected halfway up the height of the sheathing board 10, but the injection of the filling material 40 can be continued until the filling material 40 reaches the height of the extension board 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 sheathing plate 10 is a generally flat member having a front surface 10a and a back surface 10b. The front surface 10a of the sheathing plate 10 is the surface that comes into contact with the filling material 40, and the back surface 10b is the surface to which the crosspiece material 20 is attached and reinforced. In addition, a plurality of crosspiece attachment portions 11 are erected on the back surface 10b of the sheathing plate 10. In addition, a plurality of fixing holes 12, 13 are provided at the upper and lower ends of the sheathing 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 sheathing board 10 has a transparent region made of a material that transmits visible light. In this embodiment, an example is shown in which the entire sheathing board 10 is made into a transparent region. The material that constitutes the transparent region is not limited, but 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 conserve resources and to recycle the sheathing board 10. By providing the transparent region in the sheathing board 10, as shown in FIG. 1, the construction status of the filling material 40 to be filled can be visually observed from the outside from the stage of injecting the filling material 40. The size of the sheathing board 10 is not limited, but it can be about the same as a plywood board, for example, 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 the crosspiece material 20, which is formed integrally with the sheathing plate 10 and stands in a direction away from the back surface 10b. In this embodiment, the crosspiece attachment portion 11 is shown as a pair of two approximately plate-shaped clamping pieces, but the specific structure of the crosspiece attachment portion 11 is not limited. As shown in Figures 1 and 2, in this embodiment, the crosspiece attachment portions 11 are arranged in a matrix shape along the longitudinal direction of the sheathing plate 10, and also in a width direction perpendicular to the longitudinal direction. In Figure 1, the sheathing plate 10 is provided vertically with respect to the ground, so an example is shown in which the crosspiece material 20 is attached vertically, but when the sheathing plate 10 is tilted at a predetermined angle, a retaining material such as a pipe can be placed between the crosspiece attachment portions 11 arranged in a 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。 2, the crosspiece attachment portion 11 is provided with a fixing hole 11a. A fastening member 50 can be inserted into the fixing hole 11a as described below, so that the crosspiece 20 can be fixed to the crosspiece attachment portion 11. The crosspiece attachment portion 11 has a pair of clamping pieces arranged opposite each other, and a crosspiece insertion portion 11b is formed between the clamping pieces with a predetermined distance d. The size of the crosspiece attachment portion 11 is not limited, but for example, a crosspiece having a length of 157 mm, a height of 40 mm, and a thickness of 2 mm facing each other with a predetermined distance d = 25 mm can be used. The distance between the crosspiece attachment 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, 13 are through holes provided at the upper and lower ends of the sheathing board 10, and are portions through which fastening members such as screws and nails can be inserted from the front surface 10a side to the back surface 10b side of the sheathing board 10. When reinforcing the back surface 10b side of the sheathing board 10 by providing a frame member in the width direction at the lower end edge 10c and the upper end edge 10d, the frame member can be fixed by inserting a fastening member such as a screw or nail into the fixing holes 12, 13. Here, an example in which the fixing holes 12, 13 are provided is shown, but the fixing holes 12, 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 attachment portion 11 and reinforces the sheathing board 10. The thickness of the crosspiece 20 is set to a size that allows the crosspiece 20 to be inserted into the crosspiece insertion portion 11b, and the length is equal to or greater than the length of the sheathing board 10. By using a crosspiece 20 that is longer than the length of the sheathing board 10, an extension plate 30 can be fixed to the portion that protrudes beyond the upper or lower end of the sheathing board 10, allowing it to accommodate construction heights that are greater than the length of the sheathing board 10. The specific configuration of the crosspiece 20 is not limited, but crosspieces, which are wood that are standardized to 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-like member arranged adjacent to the upper or lower end of the sheathing plate 10, and the crosspiece 20 is attached to the back surface 10b. The surface of the extension plate 30 is approximately flush with the surface 10a of the sheathing plate 10, and the formwork 100 is formed by combining the sheathing plate 10 and the extension plate 30. Although an example using the extension plate 30 is shown in FIG. 1, if the construction height can be secured with the sheathing plate 10 alone, the extension plate 30 may be omitted. The configuration of the extension plate 30 is not limited, and a resin plate or plywood board that transmits visible light can be used. By fixing the extension plate 30 to the crosspiece 20, the size deficiency of the sheathing plate 10 can be compensated for by simply attaching the extension plate 30 at the work site. This eliminates the need to secure multiple sizes of sheathing plate 10 and transport them to the work site, and it becomes possible to respond to various construction works with only the sheathing plate 10 of a standardized size.
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 and is filled between the formwork 100 during construction, and hardens over time; known concrete materials can be used. There are no limitations on the material of the filling material 40, but since it hardens while in contact with the surfaces of the dam board 10 and the extension board 30, it is preferable to select a material that composes the dam board 10 and the extension board 30 so that it can be easily peeled off after hardening.
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。 3 is an enlarged perspective view showing the attachment of the crosspiece 20 to the crosspiece attachment section 11. The clamping pieces of the crosspiece attachment section 11 are provided with slide restriction protrusions 11c on the opposing surfaces. The slide restriction protrusions 11c are protrusions provided protruding into the crosspiece insertion section 11b, and restrict the movement of the crosspiece 20 in the longitudinal direction when the crosspiece 20 is inserted into the crosspiece insertion section 11b. In the example shown in FIG. 3, the slide restriction protrusions 11c are linear protrusions formed by extending in a direction away from the back surface 10b of the sheathing plate 10, but the shape of the slide restriction protrusions 11c is not limited, and a dot shape, lattice shape, etc. may be used. The size of the slide restriction protrusions 11c is not limited, but in order to effectively restrict the movement of the crosspiece 20 in the longitudinal direction, it is preferable to protrude the slide restriction protrusions 11c by several mm (for example, 2 mm). In FIG. 3, an example in which three slide restriction protrusions 11c are provided on one clamping piece is shown, but the number and position 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 Figure 3, in the formwork 100 of the present invention, the crosspiece 20 is inserted into the crosspiece insertion section 11b, the crosspiece 20 is clamped by a pair of clamping pieces, and a fastening member 50 such as a screw is inserted into the fixing hole 11a to attach and fix the crosspiece 20 to the crosspiece attachment section 11. Here, the spacing d between the clamping pieces is approximately the same as the thickness of the crosspiece 20, and the sliding restriction protrusion 11c protrudes into the crosspiece insertion section 11b, so that when the crosspiece 20 is inserted into the crosspiece insertion section 11b, the sliding restriction protrusion 11c bites into the crosspiece 20, restricting 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 this embodiment has a dam board 10 having at least a partial transparent area that transmits visible light, and a plurality of batten attachment portions 11 erected on the back surface 10b side of the dam board 10 along the longitudinal direction of the dam board 10. This makes it possible to visually check the construction status of concrete pouring and reduces the workload 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。 The crosspiece attachment section 11 also has a pair of clamping pieces arranged at a predetermined interval in the width direction perpendicular to the longitudinal direction, and a sliding restriction protrusion 11c is provided on the opposing faces of the clamping pieces. This restricts the movement of the crosspiece 20 in the longitudinal direction by the sliding restriction protrusion 11c, suppressing the crosspiece 20 from coming loose or shifting out of position, and facilitating the work of fixing the crosspiece to the crosspiece attachment section 11.
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。 The batten attachment sections 11 are arranged in a matrix along the width and length directions perpendicular to the length direction, making it easy to attach multiple batten members 20 to reinforce the sheathing board 10. As the batten attachment sections 11 are also separated in the length direction, pipes or the like can be placed along the width direction in areas where there are no batten attachment sections 11, making it possible to carry out construction on inclined or horizontal surfaces.
