この実施形態に用いる各構成要素の材料や寸法などは、次の通りであるが、これに限定されるものではない。

接続部材７は、外径10mm、長さ2460mmの棒状の鋼材から構成される。 The material and dimensions of each component used in this embodiment are as follows, but are not limited thereto.
As shown in FIG. 8, the top end indicating member 10 is made of a strip-shaped steel material having a length L = 2498 mm, a width W = 32 mm, and a plate thickness 4.0 mm.
The connecting member 7 is made of a rod-shaped steel material having an outer diameter of 10 mm and a length of 2460 mm.

また、円柱部材４には、M12（外径12mmのメートルネジ）の鋼材ネジを所定長さに切断して用いている。

なお、支持台５の溝５ａの代りに穴を形成して、接続部材７の先端をその穴に挿入して固定するようにしてもよい。 Further, a steel material screw of M12 (metric screw having an outer diameter of 12 mm) is used as the cylindrical member 4 by cutting it into a predetermined length.

A hole may be formed instead of the groove 5a of the support base 5, and the tip of the connection member 7 may be inserted into the hole and fixed.

［コンクリート打設面の指示方法］
このような構成を有する天端設定装置１と、接続部材７と、天端指示部材１０とを用いてコンクリートの打設面（天端）を指示する方法を、次に説明する。 [Concrete casting surface instruction method]
Next, a method for instructing a concrete placing surface (top end) using the top end setting device 1, the connecting member 7, and the top end indicating member 10 having such a configuration will be described.

まず、図５と図６に示すように、複数の天端設定装置１を地盤上に設置する。
次に、隣接する２つの天端設定装置１の一方の溝５ｂに接続部材７の一端を押し込んで固定すると共に、他方の天端設定装置１の溝５ｂに接続部材７の他端を押し込んで固定する。順次、この手順をくり返してすべての天端設定装置１を互いに接続部材７によって十字方向から接続する（図６）。これによって、各天端設定装置１がピッチＰ＝2.5mで正確に位置決めされる。 First, as shown in FIGS. 5 and 6, a plurality of top end setting devices 1 are installed on the ground.
Next, one end of the connecting member 7 is pushed into and fixed to one groove 5b of two adjacent top end setting devices 1, and the other end of the connecting member 7 is pushed into the groove 5b of the other top end setting device 1. Fix it. Sequentially, this procedure is repeated to connect all the top end setting devices 1 to each other from the cross direction by the connecting members 7 (FIG. 6). Thereby, each top end setting device 1 is accurately positioned at a pitch P = 2.5 m.

次に、図５に示すように、各天端設定装置１を固定ボルト８を用いて地盤に固定する。次に、図７に示すように、各天端設定装置１の保持部材２にレーザー検出器９を設置し、基準の天端高さを示すレーザビームＬＢをレーザ検出器９に照射する。   Next, as shown in FIG. 5, each top end setting device 1 is fixed to the ground using fixing bolts 8. Next, as shown in FIG. 7, a laser detector 9 is installed on the holding member 2 of each top end setting device 1, and a laser beam LB indicating a reference top end height is irradiated to the laser detector 9.

レーザ検出器９の所定位置にレーザビームＬＢが受光されるように、作業者は円柱部材４（直径12mm）を手動で軸中心に時計方向又は反時計方向に回転させ、雄ネジ部４ａと雌ネジ部５ａとの螺合作用により保持部材２の高さを調整する。   The operator manually rotates the cylindrical member 4 (diameter 12 mm) clockwise or counterclockwise about the axis so that the laser beam LB is received at a predetermined position of the laser detector 9, and the male screw portion 4a and female The height of the holding member 2 is adjusted by a screwing action with the screw portion 5a.

全ての保持部材２の高さ調整が完了すると、次に、図８に示す天端指示部材１０を、図９、図１０に示すように、順次、隣接する２つの天端設定装置１の保持部材２間に懸け渡し、固定ビス２ｂで保持部材２を円柱部材４に固定する。これによって、図１０に示すように、すべての天端指示部材１０は、ピッチＰ＝2.5mで配置されると共に、所望の天端高さを指示することになる。 When the height adjustment of all the holding members 2 is completed, the top end indicating member 10 shown in FIG. 8 is then held by the two adjacent top end setting devices 1 as shown in FIGS. It is suspended between the members 2 and the holding member 2 is fixed to the cylindrical member 4 with a fixing screw 2b. As a result, as shown in FIG. 10, all the top end indicating members 10 are arranged at a pitch P = 2.5 m and indicate a desired top end height.

［打設面の仕上げ方法］
次に、このように設定された天端指示部材１０を用いてコンクリートの打設面を仕上げる方法を説明する。
まず、図１１に示すように、地盤１３上に天端指示部材１０が隠れるまで生コンクリート１１を供給する。 [Finishing surface finishing method]
Next, a method for finishing the concrete placement surface using the top end indicating member 10 set in this way will be described.
First, as shown in FIG. 11, the ready-mixed concrete 11 is supplied until the top end indicating member 10 is hidden on the ground 13.

次に、作業者は、図１２，図１３に示すように、均し用具（トンボ）１２の均し板（長さ３ｍ）１２ａを、平行に配列された２つの天端指示部材１０上に直交する方向に渡し、均し板１２ａの中央に直角に設けられた把手１２ｂを矢印（図１２，図１３）の方向に向って引っ張る。   Next, as shown in FIGS. 12 and 13, the operator places the leveling plate (length 3 m) 12a of the leveling tool 12 on the two top end indicating members 10 arranged in parallel. It passes in the direction orthogonal, and pulls the handle 12b provided at a right angle in the center of the leveling plate 12a in the direction of the arrow (FIGS. 12 and 13).

それによって、均し板１２ａは天端指示部材１０上を摺動するので、生コンクリート１１は天端指示部材１０の指示する高さに一様に均され、打設されたコンクリート表面が精度よく均一に仕上げられる。   As a result, the leveling plate 12a slides on the top end indicating member 10, so that the ready-mixed concrete 11 is uniformly leveled to the height indicated by the top end indicating member 10, and the placed concrete surface has a high accuracy. Finished uniformly.

なお、この実施形態では図７に示すように各レーザー検出器９に水平方向のレーザービームＬＢを照射してコンクリート仕上げ面が水平になるようにしたが、水平方向に対して、例えば、０．５〜１度の角度だけ傾斜したレーザービームを用いれば、天端指示部材１０は水平に対してその角度で傾斜するように設定される。   In this embodiment, as shown in FIG. 7, each laser detector 9 is irradiated with a laser beam LB in the horizontal direction so that the concrete finish surface becomes horizontal. If a laser beam tilted by an angle of 5 to 1 degree is used, the top end indicating member 10 is set to tilt at that angle with respect to the horizontal.

従って、生コンクリート１１の表面はその傾斜を有するように仕上げられることになる。これは、例えば水はけ用の勾配を必要とするビルの屋上や食品工場の床面などのコンクリート打設面の仕上げにきわめて有効である。   Therefore, the surface of the ready-mixed concrete 11 is finished to have the inclination. This is very effective for finishing concrete placing surfaces such as rooftops of buildings that require drainage gradients and food factory floors.

なお、図１２，図１３に示す均し用具（トンボ）１２の均し板１２ａにバイブレータ（振動装置）を搭載し、均し板１３ａにコンクリートの打設表面に対して直交する方向に数十〜数百Ｈｚの微振動を与えることにより、均し板１２ａをさらに小さい引っぱり力で、円滑に天端指示部材１０上で摺動させることができる。   In addition, a vibrator (vibration device) is mounted on the leveling plate 12a of the leveling tool (dragonfly) 12 shown in FIGS. 12 and 13, and the leveling plate 13a is several tens in the direction orthogonal to the concrete placement surface. By applying a slight vibration of up to several hundred Hz, the leveling plate 12a can be smoothly slid on the top end indicating member 10 with a smaller pulling force.
