る工法である。2. Description of the Related Art In a slip form method, opposed form panels are supported by a gate-shaped frame called a yoke, and concrete is poured into the form panels while the yoke is continuously raised by a hydraulic jack or the like. By doing so, it is a construction method that can construct a tower-shaped RC structure in a short time.

てきた。[0003] Conventionally, many structures constructed by the slip-form construction method have a circular horizontal cross-section, but recently, they have a complex shape different from a circle in consideration of the scenery and design. In addition, there has been an increasing need to construct a structure in which the circumference and the gradient of the wall surface change in the height direction.

士の取り合いの変化を吸収する必要がある。If the distance between the yokes and the inclination of the formwork change in the height direction, the contact between adjacent formwork panels also changes, so that the span adjustment called a free panel is performed. Panels need to be provided everywhere to absorb changes in the interaction between panels.
【０００６】しかしながら、このようなフリーパネルを

部分において当該壁面上に段差が生じるという問題を生
じていた。However, when a wall surface is formed using such a free panel, there has been a problem that a step is formed on the wall surface at a boundary portion with a normal form panel.

った。The belly material provided on the back surface of the form panel has, for example, a one-stage arrangement and a structure in which the length can be adjusted so as to be able to cope with a change in span length or form gradient, but as designed. However, it is not enough to secure the rigidity for maintaining the shape of the wall, and there is a limit to the wall construction accuracy.

である。In order to achieve the above-mentioned object, according to the present invention, there is provided a slip-foaming device having a form member having a predetermined opening rotatably mounted on a yoke or the like. While the support material and the form panel are respectively erected on the attached support material, the belly material bent and formed to have a predetermined curvature is connected to the opening of the connection member erected on the support material and the connection erected on the form panel. It is loose through the opening of the member.

ることなくそのまま水平移動する。Then, for example, two bellows vertically arranged in two stages vertically move by a predetermined horizontal distance corresponding to the rotation angle of the support member and the distance from the rotation center, respectively. Is free to rotate around its own axis because it passes through the connecting member on the supporting material side. Therefore, the curved belly material moves horizontally without changing the bending direction.

材の動きに追随して同じ角度だけ勾配が変化する。[0013] Further, since the web material is likewise loosely penetrating the connecting member fixed to the form panel, the form panel has a difference in horizontal movement distance between the upper and lower two-stage material. Relative to the belly material by an angle corresponding to the above, and eventually the gradient changes by the same angle following the movement of the support material.

できる。Here, the form panel is rotated by a slight angle around the normal direction of the panel surface with the change of the gradient, and as a result, a gap may be formed between the panels. In the case where the overlap margin of a predetermined width is provided in at least one of the above, the occurrence of such a gap can be absorbed in the overlap margin.

直状態に至るまで徐々に変化する。FIG. 5 shows the form 1 along the outer wall surface of the projection 15.
1 shows a state in which one mold panel 21 is slid upward. Here, the convex portion 15 has a constant curvature and a constant wall length in the height direction, but the gradient of the wall surface gradually changes from the initial inclined state to the almost vertical state as can be seen in FIG. I do.
【００２８】なお、かかる壁面の勾配の変化は、図１

線方向回りの回転として現れる。The change in the gradient of the wall surface is shown in FIG.
At 45 °, 135 °, 225 ° and 315 ° referred to in (b), it appears as rotation around the short axis of the form panel, but in the vicinity of the boundary with the recess 16, around the direction normal to the form panel. Appears as rotation.
【００２９】したがって、以下、パネル位置が４５゜方

当該支持材１２の勾配を変化させる。First, when the panel position is in the 45.degree. Direction, as the form panel 21 is slid upward, as shown in FIG. Rotate the material 12 about the center of rotation 14;
The gradient of the support 12 is changed.

の軸線回りに回転することはない。Then, two belly members 23 and 25 vertically arranged in two stages by a predetermined horizontal distance corresponding to the rotation angle of the support member 12 and the distance from the rotation center 14 respectively move horizontally. Since the belly members 23 and 25 pass through the U-shaped bolts 31 and 32 on the support member 12 side, they do not rotate around their own axes.

て同じ角度だけ勾配が変化する。Since the belly members 23 and 25 also penetrate the U-shaped bolts 22 and 24 fixed to the form panel 21 in the same manner, the form panel 21 is vertically 3B, the support material 12 rotates relative to the belly material 23, 25 by an angle corresponding to the difference in the horizontal movement distance of the belly material 23, 25. As a result, the movement of the support material 12 can be clearly understood from FIG. , The gradient changes by the same angle.
【００３４】次に、パネル位置が凹部１６の近傍にある
場合においては、立ち上がり当初は図６(a) および図６

おいて幅ｗだけ互いに重ねながら斜めに配置される。Next, when the panel position is in the vicinity of the concave portion 16, at the beginning of the rise, FIGS.
As shown in (b), the form panels 21 are arranged obliquely while overlapping each other by the width w at the overlap margin 41 thereof.

に示すように、ほぼ垂直位置となる。When the form panel 21 is slid upward in this state, the form panel 21 is gradually rotated around its normal direction while being firmly held in the wall direction by the belly members 23, 25. Eventually, FIG. 6 (c) and FIG. 6 (d)
As shown in FIG.

すことはない。Here, when the form panel 21 changes from the oblique arrangement state to the vertical arrangement state, a gap d determined by the width of the form panel 21 and the initial oblique arrangement angle forms a gap d between the adjacent form panels 21. But the gap d
Is absorbed by the width w of the overlapping margin 41, and the concrete wall surface is not exposed in the gap d and the ready-mixed concrete does not leak.

And the size of the play with the belly materials 23 and 25 are adjusted in advance.
The width w of the overlap margin 41 is determined so as not to fall below the gap d.

寸法調整する必要がない。As described above, according to the formwork of the slip-form apparatus of the present embodiment, a round pipe curved and formed in accordance with the curvature of the designed wall surface is used as the belly material, and the belly material and the formwork are formed. The connection to the panel and the connection to the support
Since the predetermined play is provided between the U-shaped bolt and the U-shaped bolt, when changing the gradient of the formwork panel, the belly material itself does not rotate, but simply transmits the horizontal force. It acts as a member that does. In addition, the rotation of the form panel around the normal direction due to the change in the gradient is absorbed by the gap between the outer peripheral surface of the web member and the U-shaped bolt, and it is not necessary to adjust the dimensions of the web member itself.

Therefore, desired rigidity can be given to the belly material, and the construction accuracy of the designed wall surface can be improved.

It was necessary to form the free panel with a certain thickness, so that it was not possible to avoid generating a large step on the wall surface.
