Description

本発明は養生シート用フレームの構造に関するものである。   The present invention relates to a structure of a frame for a curing sheet.

打ち終わったコンクリートは、その水和反応により十分に強度を発現し、所要の耐久性、水密性、鋼材を保護する性能等の品質を確保し、有害なひび割れを生じないようにするために、打込み後一定期間は、コンクリートを適当な温度のもとで、十分湿潤状態に保ち、且つ有害な作用の影響を受けないようにすることが必要であり、そのための作業をコンクリートの養生という。
コンクリートは、打ち込み後ごく早い時期に表面が乾燥して内部の水分が失われると、セメントの水和反応が十分に行われず、また、特に表面だけが急激に乾燥すると、ひび割れの発生の原因となるからである。
トンネルのコンクリートにおいても、その湿潤状態に保ち、温度を制御する養生を行う必要がある。
そのための養生装置の一例を図6に示すと、養生シートを周囲に取り付けたフレームaを、トンネル軸方向に移動可能に配置し、打設直後のコンクリートbの表面に一定の間隔cを保持して養生シートdを位置させ、その間隔cに温風や加熱した水蒸気を供給する方法が知られている。
In order to ensure that the finished concrete has sufficient strength due to its hydration reaction, ensuring the required durability, watertightness, performance to protect steel, etc., and not causing harmful cracks, For a certain period of time after placing, it is necessary to keep the concrete sufficiently moistened under an appropriate temperature and not to be affected by harmful effects, and the work for this is called concrete curing.
If the surface of concrete is dried and the internal moisture is lost very early after placing, the hydration reaction of the cement will not be carried out sufficiently, especially if only the surface is dried rapidly. Because it becomes.
Also in the concrete of the tunnel, it is necessary to carry out curing to keep the wet state and to control the temperature.
An example of a curing apparatus for this purpose is shown in FIG. 6. A frame a having a curing sheet attached around is arranged so as to be movable in the tunnel axis direction, and a certain distance c is maintained on the surface of the concrete b immediately after placing. There is known a method in which the curing sheet d is positioned and hot air or heated water vapor is supplied to the interval c.

前記した従来の養生シート用フレームの構造にあっては、次のような問題点がある。
<1> トンネルの内周面を二分割、三分割したアーチ状の長尺部材を現場に搬入して組み立てて使用している。
<2> この長尺部材はH形鋼をアーチ状に曲げ加工して製造したものであり、トンネルの内径に沿って形成するから、トンネルごとに内径に合わせて製造する必要があって不経済である。
<3> 長尺の部材であるから、運搬に手数を要し効率的ではない。
The structure of the conventional frame for curing sheet described above has the following problems.
<1> An arch-shaped long member obtained by dividing the inner peripheral surface of the tunnel into two parts and three parts is brought into the field and assembled for use.
<2> This long member is manufactured by bending an H-shaped steel into an arch shape, and is formed along the inner diameter of the tunnel. It is.
<3> Since it is a long member, it requires a lot of work and is not efficient.

上記のような課題を解決する本発明の養生シート用フレームの構造は、トンネルの内面を養生する養生シートを取り付ける、トンネルの内面とほぼ相似形のフレームであって、そのフレームは複数本の直材と、両側の側面が平行ではない複数個の台形材とにより構成し、予定のフレームの最終形状を形成するに適した角度を備えた台形材を選択し、台形材の非平行板の側面に直材の端板を取り付けることで、直材を非直線状態に延長して組み立て、結果としてトンネルの内面とほぼ相似形のフレームとして構成したことを特徴とするものである。
また本発明の養生用フレームは、前記の複数の台形材を用意し、各台形材ごとに非平行板の延長線の交差角度が異なるものであるように構成したことを特徴とするものである。
The structure of the curing sheet frame of the present invention that solves the above-described problems is a frame that is substantially similar to the inner surface of the tunnel, to which the curing sheet for curing the inner surface of the tunnel is attached. A trapezoidal material with an angle suitable for forming the final shape of the planned frame, and a side surface of the non-parallel plate of the trapezoidal material. By attaching an end plate of straight material to the straight plate, the straight material is extended and assembled in a non-linear state, and as a result, it is configured as a frame that is substantially similar to the inner surface of the tunnel.
Further, the curing frame of the present invention is characterized in that the plurality of trapezoidal materials are prepared, and the crossing angles of the extension lines of the non-parallel plates are different for each trapezoidal material. .

本発明の養生シート用フレームの構造は以上説明したようになるから次のような効果を得ることができる。
<1> 現場ごとにトンネルの内面の形状が異なっても、台形材を変更するだけで、同一の直材を転用することができる。したがってきわめて経済的である。
<2> 従来のようにトンネルの内面形状を二分割、三分割したアーチ状部材を現場に運搬して組み立てる場合と比較すると、多数本に分割した直材を扱うために、運搬、組み立てがきわめて容易となる。例えば従来の長尺のアーチ状部材を運搬するのに3台の10t車を必要としたものが、短い直材を平行に積み上げることで、1台の10t車で運搬をすることができた。
<3> 直材が短かく、その間に台形材を介在させるから、現場での組み立て作業が簡単で安全である。
<4> 市販のパイプなどに曲げ加工を施す必要がなく、そのまま使用できるから、製造、保管、運搬、組み立て作業が容易、経済的であり安全である。
Since the structure of the frame for curing sheets of the present invention is as described above, the following effects can be obtained.
<1> Even if the shape of the inner surface of the tunnel differs from site to site, the same straight material can be diverted simply by changing the trapezoidal material. It is therefore very economical.
<2> Compared to the case where the arch-shaped member divided into two or three parts is transported to the site and assembled as before, the handling and assembly are extremely difficult to handle. It becomes easy. For example, a conventional long arch-shaped member that requires three 10t vehicles can be transported by one 10t vehicle by stacking short straight materials in parallel.
<3> Since the direct material is short and a trapezoidal material is interposed between them, the assembly work at the site is simple and safe.
<4> Since it is not necessary to bend a commercially available pipe or the like and it can be used as it is, it is easy to manufacture, store, transport and assemble, and is economical and safe.

以下図面を参照にしながら本発明の養生シート用フレームの構造の好適な実施の形態を詳細に説明する。   Hereinafter, preferred embodiments of the structure of a frame for a curing sheet of the present invention will be described in detail with reference to the drawings.

<1>用途。
前記したように本発明の養生シート用フレームは、トンネルのコンクリートの打設が終わった段階で使用するものである。
打設直後のトンネルコンクリートの内面を養生するために、トンネルの内面とほぼ相似形のフレームで構成し、その外側に養生シートを取り付けて使用する。
<1> Use.
As described above, the frame for a curing sheet of the present invention is used at the stage where the concrete for the tunnel has been placed.
In order to cure the inner surface of the tunnel concrete immediately after placing, it is composed of a frame that is almost similar to the inner surface of the tunnel, and a curing sheet is attached to the outside of the frame.

<2>構成部材。
本発明のフレームは複数本の直材1と、直材1の間に介在させる台形材2とによって構成する。
<2> Components.
The frame of the present invention includes a plurality of straight members 1 and a trapezoid member 2 interposed between the straight members 1.

<3>直材。
直材1はフレームの全体を構成する主要部材である。
直材1は、例えば長さ数mのパイプやH形鋼で構成する。
この直材1は従来のようにアーチを形成していないから、曲げ加工が不要であって、市販のパイプなどを切断してそのまま利用することができ、きわめて経済的である。
直材1の端部には直交する状態で端板11を取り付け、この端板11のボルト穴にボルトを通して、台形材2と一体化をはかる。
図面の実施例では直材1を2本の平行なパイプで構成し、両パイプ間を連結板12で連結して補強したものである。
<3> Direct material.
The direct material 1 is a main member constituting the entire frame.
The direct material 1 is composed of, for example, a pipe having a length of several meters or an H-shaped steel.
Since the straight member 1 does not form an arch as in the prior art, bending is not required, and a commercially available pipe can be cut and used as it is, which is extremely economical.
An end plate 11 is attached to the end portion of the straight member 1 in a state of being orthogonal to each other, and bolts are passed through the bolt holes of the end plate 11 to integrate with the trapezoidal member 2.
In the embodiment of the drawing, the straight member 1 is constituted by two parallel pipes, and the two pipes are connected by a connecting plate 12 to be reinforced.

<4>台形材。
台形材2は鋼板で組み立てたブロック状の六面体の部材である。
台形材2は側面視が台形を呈し、両側の側面は平行ではない、非平行板21を備えている。
非平行板21の寸法、形状は、前記した直材1の端板11の寸法、形状と同一に形成する。
両側の非平行板21の間は長さの異なる平行板22で連結する。
非平行板21、および平行板22に直交する面は、壁板で閉塞して六面を備えた箱状体として形成することもできる。
非平行板21にはボルト穴23を開口して、前記した直材1の端板11のボルト穴とを貫通したボルトで一体化を図る。
<4> Trapezoidal material.
The trapezoidal material 2 is a block-shaped hexahedral member assembled from steel plates.
The trapezoidal material 2 includes a non-parallel plate 21 that has a trapezoidal side view and is not parallel on both side surfaces.
The dimensions and shape of the non-parallel plate 21 are the same as the dimensions and shape of the end plate 11 of the straight member 1 described above.
The non-parallel plates 21 on both sides are connected by parallel plates 22 having different lengths.
The non-parallel plate 21 and the plane orthogonal to the parallel plate 22 can be formed as a box-like body having six sides by closing with a wall plate.
Bolt holes 23 are opened in the non-parallel plate 21, and integration is achieved with bolts that penetrate the bolt holes of the end plate 11 of the straight member 1 described above.

<5>組み立て。(図4)
フレームを構成するには、直材1の間に台形材2を介在させて行う。
すなわち、台形材2の非平行板21の表面に、直材1の端板11をボルトで締結して取り付ける。
そのために、複数本の直材1を順次、非直線状態に延長して組み立てることができる。
その結果としてトンネルBの内面から養生空間Cだけ離れてほぼ相似形のフレームAを構成することができる。
このフレームAのトンネルB側に養生シートDを取り付け、養生空間Cに温風や加熱した蒸気を供給して養生を行う。
<5> Assembly. (Fig. 4)
In order to configure the frame, the trapezoidal material 2 is interposed between the direct members 1.
That is, the end plate 11 of the straight member 1 is fastened and attached to the surface of the non-parallel plate 21 of the trapezoidal member 2 with a bolt.
Therefore, it is possible to assemble a plurality of straight members 1 by sequentially extending them in a non-linear state.
As a result, a frame A having a substantially similar shape can be formed by being separated from the inner surface of the tunnel B by the curing space C.
A curing sheet D is attached to the tunnel B side of the frame A, and curing is performed by supplying warm air or heated steam to the curing space C.

<6>複数種類の台形材。(図5)
その際に、複数の種類の台形材2を用意しておく。
複数の種類とは、非平行板21の延長線の交差する角度αが異なるものの意味である。
先にトンネルの形状が決まり、それを養生するフレームAの形状は決まっている。
そこで、台形材2を複数本の直材1の間に介在させた場合に、予定のフレームAの最終形状を形成するに適した交差角度αを備えた台形材2を選択する。
選択は工場や倉庫において行い、選択した台形材2の複数個と、複数本の直材1を現場に運搬して、上記のようにフレームを組み立てる。
運搬する対象は、アーチ状に曲がった長い部材は存在せず、複数本の比較的短い直線状の直材と、ブロック状の台形材2であるから、多数本を積み上げて運搬することができ、保管も取扱いも容易で経済的である。
<6> Multiple types of trapezoidal materials. (Fig. 5)
At that time, a plurality of types of trapezoidal materials 2 are prepared.
The term “plurality” means that the angles α at which the extension lines of the non-parallel plate 21 intersect are different.
The shape of the tunnel is determined first, and the shape of the frame A for curing it is determined.
Therefore, when the trapezoidal material 2 is interposed between the plurality of straight members 1, the trapezoidal material 2 having an intersection angle α suitable for forming the final shape of the predetermined frame A is selected.
The selection is performed in a factory or a warehouse, and the plurality of selected trapezoidal materials 2 and the plurality of direct materials 1 are transported to the site, and the frame is assembled as described above.
The object to be transported is not a long member bent in an arch shape, and is a plurality of relatively short straight straight members and a block-shaped trapezoidal member 2, so that many can be stacked and transported. It is economical and easy to store and handle.
