〔産業上の利用分野〕
この発明はコンクリート法枠を打設する時に用いる筒状
型枠に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cylindrical formwork used when pouring concrete frames.
コンクリート法枠を打設する場合、従来から用いられて
いる半筒状の型枠では、地山と型枠の間の空隙からコン
クリートが漏れるので、この解決のため発明者は、特願
昭55−25624号、特願昭58−125695号、
特願昭61−262962号などにより可撓性シートで
底面を構成した筒状型枠を提案した。When pouring concrete frames, the semi-cylindrical formwork used conventionally causes concrete to leak from the gap between the ground and the formwork.To solve this problem, the inventor filed a patent application filed in -25624, patent application No. 125695-1980,
In Japanese Patent Application No. 61-262962, we proposed a cylindrical formwork whose bottom surface was made of a flexible sheet.
型枠の全部ないし一部を可撓性シートを用いて完結した
筒状の型枠を用いることは、コンクリートの漏れを防ぎ
極めて好都合である。It is extremely convenient to use a cylindrical formwork that is completed in whole or in part using a flexible sheet to prevent leakage of concrete.
しかしながら、打設されたコンクリート体と地山とがシ
ートによって遮られるのが欠点として指摘されている。However, it has been pointed out that a drawback is that the poured concrete body and the ground are blocked by the sheet.
この発明は上記のコンクリートと地山との遮断を解決す
ることを目的としている。The purpose of this invention is to solve the above-mentioned problem of isolation between concrete and the ground.
この発明は、この目的のために、コンクリート打設に用
いる筒状型枠の底面の上下方向の中央部に、多数の開口
を設ける。For this purpose, the present invention provides a large number of openings in the vertical center of the bottom surface of the cylindrical form used for concrete pouring.
このように構成すると、打設したコンクリートは、底面
の両側の可撓性シートによって、型枠と地山との間から
の漏れは防げる上、コンクリートの一部は中央部の開口
から底面に流れ出し、コンクリート体と地山の遮断が避
けられる。With this configuration, the poured concrete can be prevented from leaking between the formwork and the ground by the flexible sheets on both sides of the bottom, and some of the concrete can also flow out to the bottom from the opening in the center. , the isolation between the concrete body and the ground can be avoided.
以下、本発明の実施例を図面について詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
第1図に示すのは筒状型枠の底面を形成する帯状の可撓
性シート10である。このシートは両側部11は通常の
平織りの織布12で構成されているが、長手方向の中央
部13は経糸がなく、緯糸14だけで構成され、従って
緯糸はある程度自由に動き、緯糸の間に開口15ができ
るように構成されている。What is shown in FIG. 1 is a band-shaped flexible sheet 10 forming the bottom surface of a cylindrical form. In this sheet, both side parts 11 are made of a normal plain-woven fabric 12, but the central part 13 in the longitudinal direction has no warp threads and is made up only of weft threads 14. Therefore, the weft threads can move freely to some extent, and between the weft threads there is no warp. The structure is such that an opening 15 is formed in the opening 15.
第2図に示すように、二本の長尺のアングル材21の所
々を、横断方向の丸棒22を用いて梯子状に連結し、上
記の可撓性シート10の両側縁をアングル材に取付けて
下型枠20を構成する。可撓性シートはアングル材の間
隔よりも幅広く、余裕をもって取付ける。As shown in FIG. 2, two long angle members 21 are connected in places in a ladder shape using transverse round rods 22, and both sides of the flexible sheet 10 are connected to the angle members. The lower formwork 20 is constructed by attaching it. The flexible sheet should be wider than the gap between the angle members, and should be installed with a margin.
第3図に示すように、凹凸のある地山30の上に下型枠
20を設置する。鉄筋能40を下型枠の上に載置し、ア
ンカー41を他山に打ち込み、下型枠・鉄筋能をアンカ
ーに緊結して固定する。その上から半筒状の上型枠50
を被せて、下型枠と連結して筒状型枠60を完成する。As shown in FIG. 3, the lower formwork 20 is installed on top of the uneven ground 30. The reinforcing bars 40 are placed on the lower formwork, the anchors 41 are driven into other threads, and the lower formwork and reinforcing bars are fastened to the anchors. From above, a semi-cylindrical upper formwork 50
The cylindrical formwork 60 is completed by covering it and connecting it with the lower formwork.
このような筒状型枠の中にコンクリート70を流し込む
。可撓性シートはコンクリートによって地山30の方へ
押しつけられ、シートの側部11は筒状型枠の下縁61
と地山との間からのコンクリートの漏れを防ぎ、シート
状物の中央部では、コンクリートは緯糸を押しのけて形
成される開口を通って他山との間に入り込む。Concrete 70 is poured into such a cylindrical form. The flexible sheet is pressed against the ground 30 by the concrete, and the sides 11 of the sheet are attached to the lower edge 61 of the cylindrical formwork.
In order to prevent concrete from leaking between the concrete and the ground, in the center of the sheet-like material, the concrete passes through the opening formed by pushing away the weft threads and enters between the other mounds.
この発明の骨子は、底面を可撓性シート状物で構成した
場合、筒状型枠の下縁と他山の間の隙間からのコンクリ
ートの漏れを防ぐが、シート状物が他山とコンクリート
を完全に隔てて仕舞う。この欠点をなくす為に、底面の
一部からコンクリートないしモルタルを漏らすことにあ
る。The gist of this invention is that when the bottom surface is made of a flexible sheet-like material, leakage of concrete from the gap between the lower edge of the cylindrical form and other piles is prevented, but the sheet-like material completely separate them. To eliminate this drawback, concrete or mortar is allowed to leak from a portion of the bottom.
従って、シート状物の長手方向の中央部にコンクリート
の漏れる程度の大きさの、即ち一辺IQmn以上の多数
の開口を設ける点が重要である。開口の形状・形成方法
は特に限定するものではないが、例えば、下記のような
方法が用いられる。Therefore, it is important to provide a large number of openings in the longitudinal center of the sheet-like material with a size large enough to allow concrete to leak, that is, with each side IQmn or more. Although the shape and forming method of the opening are not particularly limited, for example, the following method may be used.
第4図に示すように、両側部11の織布12、中央部1
3の網体16の三条を縫合して帯状に形成したもの。As shown in FIG.
Three strips of the mesh body 16 of No. 3 are sewn together to form a band shape.
第5図に示すように、全体を不織布17で形成し、その
中央部には多数の開口15を設けたもの。As shown in FIG. 5, the entire structure is made of a nonwoven fabric 17, and a large number of openings 15 are provided in the center.
第6図に示すように、両側部11を織布12で形成し、
両側の織布を所々丈夫な紐18で横断的に連結したもの
、などである。As shown in FIG. 6, both side portions 11 are formed of woven fabric 12,
For example, woven fabrics on both sides are connected transversely with strong strings 18 in places.
シート状物が型枠の隙間から必要以上にはみ出したりし
ないように、適宜間隔でシート状物をフッタ付きのアン
カービン等を用いて地山に固定することは有効である。In order to prevent the sheet-like material from protruding beyond the gap in the formwork more than necessary, it is effective to fix the sheet-like material to the ground using anchor bins with footers at appropriate intervals.
半筒状の上型枠50はその素材・形状は規定されるもの
ではなく、鉄・アルミ・プラスチック・木など剛性のあ
る素材の他、織布・不織布・ゴムシートなど可撓性素材
で構成してもよい。The semi-cylindrical upper formwork 50 is not limited in its material or shape, but may be made of rigid materials such as iron, aluminum, plastic, or wood, as well as flexible materials such as woven fabric, nonwoven fabric, or rubber sheet. You may.
この発明は上記のように構成されているので、底面の可
撓性シートの中央部の開口から、コンクリートが漏れ、
コンクリート体と地山が完全に隔離されることがなく、
不安感が除去される。Since this invention is constructed as described above, concrete leaks from the opening in the center of the bottom flexible sheet.
The concrete body and the ground are not completely isolated,
Anxiety is removed.
