Description
【０００１】[0001]
本考案は、シールド工法や推進工法に用いられるコンクリート製のトンネルラ イナの遠心成形型枠の仕切板の構造に関する。 The present invention relates to the structure of a partition plate of a centrifugally molded formwork of a concrete tunnel liner used in a shield construction method and a propulsion construction method.
【０００２】[0002]
シールド工法や推進工法に用いられるトンネルライナを、円弧板状に分割して 遠心成形により製造する場合、必然的に、遠心成形ドラム内に仕切板を設けて、 その仕切板内にコンクリ−トを打設する必要がある。この場合仕切板は遠心力に よるコンクリ−トの側圧を受けて背面側に倒れる方向の力を受ける。この場合に 、仕切板が少しでも変形すると、コンクリート端面を正確に成形することができ ない。トンネルライナはこの仕切板によって形成される面が隣接ライナとの当接 面になるので、この面の部分の形状が正確でないと、水密性が低下し、トンネル ライナとしての品質が著しく害される。また一度変形した仕切板は補修が容易で ないので、結局、新規取替を要し、短寿命となる。 When the tunnel liner used in the shield construction method and the propulsion construction method is divided into arc plates and manufactured by centrifugal molding, a partition plate is inevitably provided in the centrifugal molding drum and the concrete is placed in the partition plate. It is necessary to set. In this case, the partition plate receives the lateral pressure of the concrete due to the centrifugal force and the force in the direction of falling to the back side. In this case, if the partition plate deforms even a little, the concrete end face cannot be accurately molded. Since the surface formed by the partition plate of the tunnel liner is the contact surface with the adjacent liner, if the shape of the part of this surface is not accurate, the watertightness is lowered and the quality as the tunnel liner is significantly impaired. Moreover, since the partition plate once deformed is not easy to repair, it eventually requires a new replacement and has a short life.
【０００３】 また、仕切板の背面側の空間はコンクリ−トが入らないように閉鎖する必要が あるが、単に周囲を固定したカバーを取付けると中央部が撓んで変形を生じ寿命 が短いという問題があり、補強を要する。Further, the space on the back side of the partition plate needs to be closed to prevent the entry of concrete, but if a cover whose peripheral part is simply fixed is attached, the central part is bent and deformed, resulting in a short service life. There is a need for reinforcement.
【０００４】[0004]
本考案者らは、このような問題を同時に解決するために、遠心成形型枠ドラム に取付ける仕切板の構造に工夫を加え、上記欠点を克服した。 本考案は、新しく開発したトンネルライナ遠心成形型枠用の仕切板を提供する ことを目的とするものである。 In order to solve these problems at the same time, the present inventors have devised the structure of the partition plate attached to the centrifugal molding form drum to overcome the above drawbacks. The present invention aims to provide a partition plate for a newly developed tunnel liner centrifugal molding formwork.
【０００５】[0005]
本考案は、上記問題を解決するために、円周方向に複数個に分割したトンネル ライナの遠心成形型枠に取付ける仕切板の背面側の頂部に、隣接仕切板間を連結 する繋ぎ材を取付け、この繋ぎ材の上面に、仕切板背面空間を覆うカバーを取付 けたことを特徴とするトンネルライナの遠心成形型枠の仕切板である。 In order to solve the above problems, the present invention attaches a connecting member for connecting adjacent partition plates to the top of the partition plate on the back side of the partition plate to be attached to the centrifugal molding form of the tunnel liner divided in the circumferential direction. A partition plate for a centrifugal molding form of a tunnel liner, characterized in that a cover for covering a space behind the partition plate is attached to an upper surface of the connecting member.
【０００６】[0006]
本考案の型枠は、遠心成形の際に、仕切板の倒れや、コンクリ−トを打設しな い仕切板間の空間部のカバーの変形を生じないから、周縁形状の正確なコンクリ −トトンネルライナを容易に製作することができ、無駄なコンクリ−トを打設す ることがなく、型枠部材の寿命が長く耐久性に富む。 The mold of the present invention does not cause the partition plates to fall down or the cover of the space between the partition plates where the concrete is not placed is not deformed during centrifugal molding. The tunnel liner can be easily manufactured, no unnecessary concrete is placed, and the life of the form member is long and rich.

以下図面を参照して本考案の実施例を説明する。 図２は本考案の適用される遠心成形ドラムでトンネルライナ１０（１０ａ、１ ０ｂ、…）を遠心成形したときのドラムの断面図を示したものである。図１は図 ２のＡ部拡大図であって、図１は本考案の実施例のトンネルライナ１０の仕切板 １、２の構造を示すものである。図１中において、隣接するトンネルライナ１０ ａ、１０ｂの仕切板１、２はドラムシェル３に取り付けられると共に、その頂部 を繋ぎ材４で結合されている。この繋ぎ材４は、仕切板１、２と一体のものでも よく、また、図示したボルト５による取り付けのように、着脱可能なものでもよ い。繋ぎ材４の断面寸法や配列数は、仕切板１、２の間隔、仕切板１、２の高さ その他の要素を勘案して設計により定めることができる。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a cross-sectional view of a centrifugal molding drum to which the present invention is applied, when the tunnel liner 10 (10a, 10b, ...) Is centrifugally molded. FIG. 1 is an enlarged view of a portion A of FIG. 2, and FIG. 1 shows a structure of partition plates 1 and 2 of a tunnel liner 10 according to an embodiment of the present invention. In FIG. 1, the partition plates 1 and 2 of the adjacent tunnel liners 10 a and 10 b are attached to the drum shell 3 and the tops thereof are joined by a connecting member 4. The connecting member 4 may be integrated with the partition plates 1 and 2, or may be detachable, such as by mounting with the bolt 5 shown. The cross-sectional size and the number of arrangement of the connecting members 4 can be determined by design in consideration of the distance between the partition plates 1 and 2, the height of the partition plates 1 and 2, and other factors.
【０００８】 カバー６は、仕切板１、２の背面側の空間にコンクリ−トが無駄に散逸するの を防止するためのもので、仕切板１、２又は繋ぎ材４にボルト７によって取付け る。 カバー６の背面にリブ材を取付け、このリブ材が上記繋ぎ材４を丁度兼用する ように構成することもできる。また、カバー６は適宜の大きさに分割し取り扱い を容易にすることもできる。またカバー６の取付け構造は、ボルト７のほか、く さび止め、シャコ万力方式、ラッチ構造などの公知の構造とすることができる。The cover 6 is for preventing the concrete from being unnecessarily dissipated in the space on the back side of the partition plates 1 and 2, and is attached to the partition plates 1 and 2 or the connecting member 4 with bolts 7. . A rib material may be attached to the back surface of the cover 6 so that the rib material also serves as the connecting material 4. Further, the cover 6 can be divided into appropriate sizes to facilitate handling. In addition to the bolt 7, the cover 6 may be attached by a known structure such as a wedge stopper, a shrimp vise method, or a latch structure.
【０００９】 実施例の繋ぎ材４を備えた仕切板１、２を用いると、トンネルライナ１０ａ、 １０ｂのコンクリ−ト端面の寸法が正確なトンネルライナを容易に製造すること ができ、また、仕切板１、２、カバー６の耐久性が向上する。By using the partition plates 1 and 2 provided with the tie member 4 of the embodiment, it is possible to easily manufacture the tunnel liner in which the dimensions of the concrete end faces of the tunnel liners 10a and 10b are accurate, and the partition line is provided. The durability of the plates 1 and 2 and the cover 6 is improved.
