Description

本考案は、コンクリート壁などの施工、補修にH鋼と共に用いられる大型の型枠、特にスライド式大型型枠の底部を固定するワイパネ足元固定金具、大型の型枠を定位置に容易に固定することができるH鋼連結具、そのH鋼留め金具、及びそれらを用いた建設用型枠に関する。   The present invention is a large formwork used with H steel for construction and repair of concrete walls, etc., especially wiper foot fixing brackets that fix the bottom of slide-type large formwork, and easily fix large formwork in place. The present invention relates to an H-steel connector, an H-steel bracket, and a construction formwork using the same.

図14に示すように建設用大型型枠18は、トンネル覆工,煙突,橋脚,ダムなどの大型のコンクリート構造物を構築する際に用いられる。スライド式型枠がよく知られている。   As shown in FIG. 14, the large formwork 18 for construction is used when constructing a large concrete structure such as a tunnel lining, a chimney, a pier, and a dam. Sliding formwork is well known.

この種のスライド式の建設用大型型枠18は、大まかに、側面に孔15aが穿設され両面に隙間15bが貫通するビーム15と、ビーム15の孔15aに通し留具などとともにビーム15同士を連結、固定する連結パイプ15iと、連結されたビームの片面に係止された金属製のパネル15kとかなる。必要に応じて、人が作業する足場であるプラットホーム12aが布板、パイプ等で組まれる。   This type of slide-type large formwork 18 for construction is roughly composed of a beam 15 having a hole 15a formed in a side surface and a gap 15b penetrating both surfaces, and a beam 15 between the beams 15 together with a fastener and the like through the hole 15a of the beam 15. Are connected to and fixed to a connecting pipe 15i and a metal panel 15k locked to one side of the connected beam. As necessary, the platform 12a, which is a scaffold for human work, is assembled with cloth boards, pipes, and the like.

建設用大型型枠18は、構造物の壁の打設、補強、崖の補強などに使用され、片壁であれば、それらの間に、コンクリートを打設し、壁を形成し、養生の後、順次上方にスライド(昇降)させ、垂直方向に壁を順次形成していく。   The large formwork 18 for construction is used for placing and reinforcing the walls of structures, reinforcing cliffs, etc. If it is a single wall, concrete is placed between them to form walls, After that, it is slid upward and downward sequentially to form walls in the vertical direction.

型枠の昇降、脱型枠およびその後の移動は型枠を分解せずにクレーンなどの重機を使用して、分解されることなく行われ、大型のコンクリート構造物の施工に大きく貢献している。   The raising and lowering of the formwork, removal of the formwork and the subsequent movement are performed without using a crane or other heavy equipment without disassembling the formwork, greatly contributing to the construction of large concrete structures. .

通常、ビーム15は、ワイドパネルビーム;「通称「ワイパネ」)と呼ばれる鋼材で、種々の長さのものが流通している。   In general, the beam 15 is a steel material called a wide panel beam (commonly known as “wipane”), and various lengths are in circulation.

図15の非特許文献1に、スライド式の建設用大型型枠18が、より詳しく説明されている。図15(A)が右側面、反パネル15k側、図15(B)が反パネル15k側の拡大斜視図である。両壁タイプで、セパレーター、Pコーン、ホームタイ(ネジ鉄筋)、タイボルトなどで、ビーム15間隔を一定に保ち、固定する。片壁の場合には、ネジ鉄筋をH鋼などに溶接で固定する。   Non-Patent Document 1 in FIG. 15 describes the slide-type large formwork for construction 18 in more detail. FIG. 15A is an enlarged perspective view of the right side surface, the side opposite to the panel 15k, and FIG. With both wall types, the beam 15 interval is kept constant and fixed with a separator, P cone, home tie (screw rebar), tie bolt, etc. In the case of a single wall, the screw rebar is fixed to H steel or the like by welding.

Connect and fix with. Further, the base anchor 15c and the rail 15g are fixed with a fastener such as a tie bolt nut 15h via a cap nut 15d.

続いて、ビーム15上部では、H鋼留め金具7をH鋼14に嵌め、ボルト11を締め、固定する。さらに、ビーム15の隙間15bを挿通したネジ鉄筋16aとH鋼留め金具7の第1ナット部9を接続し、他端はタイボルトナット16bなどの留具で固定する。   Subsequently, at the upper part of the beam 15, the H steel fastener 7 is fitted into the H steel 14, and the bolt 11 is tightened and fixed. Furthermore, the screw rebar 16a inserted through the gap 15b of the beam 15 and the first nut portion 9 of the H steel fastener 7 are connected, and the other end is fixed with a fastener such as a tie bolt nut 16b.

このようにして、ビーム15とH鋼14を接続するH鋼留め金具7と、ネジ鉄筋16aタイボルトナットなどの留具で本願考案のH鋼連結具16を構成する。   In this way, the H steel coupler 16 of the present invention is constituted by the H steel fastener 7 connecting the beam 15 and the H steel 14 and the fastener such as the screw rebar 16a tie bolt nut.

次に、埋め込みアンカー15fをビームに係止するとともに、コンクリート17をパネル15kとH鋼14の間に打設し、養生する。その後、スライド式大型型枠12をリフトし、埋め込みアンカー15fにビーム15底部を固定し、ビーム15上部はH鋼連結具16で所定の幅になるよう固定する。このように順次コンクリート17を打設して、コンクリート17の建造物を上方に施工していく。   Next, the embedded anchor 15f is locked to the beam, and the concrete 17 is placed between the panel 15k and the H steel 14 and cured. Thereafter, the slide-type large formwork 12 is lifted, the bottom of the beam 15 is fixed to the embedded anchor 15f, and the top of the beam 15 is fixed to a predetermined width by the H steel connector 16. In this way, the concrete 17 is sequentially placed, and the building of the concrete 17 is constructed upward.

本考案であるワイパネ足元固定金具、H鋼連結具、そのH鋼留め金具からなる建設用型枠は、設置、スライドが容易で、かつ型枠の安全性を有するため、コンクリート壁などの施工、補修等の建設業界に大きく貢献する。   The construction formwork consisting of the wiper foot fixing bracket, the H steel connector, and the H steel fastener, which is the present invention, is easy to install and slide and has the safety of the formwork. Contributes greatly to the construction industry such as repairs.
