By doing so, it is a construction method that can construct a tower-shaped RC structure in a short period of time.

In the past, many structures constructed by the slip-form construction method had a circular horizontal cross section, but recently, with emphasis on landscape and design, the structure has a complicated shape different from a circle. In addition, there is an increasing need for constructing structures whose circumference changes in the height direction.

Here, for example, when the circumference becomes shorter, it is necessary to sequentially remove the unnecessary formwork panels.

However, the formwork panel is firmly pressed against the concrete wall surface by the upholstery material arranged on the back surface thereof, and the formwork panel is sandwiched between the upholstery material and the concrete wall surface. It was not easy to pull out the frame panel.

Further, the abdominal material itself must be shortened in accordance with the change in the circumferential length, but in the past, it had to be cut with gas each time, which was also a time-consuming operation.

The present invention has been made in consideration of the above-mentioned circumstances, and is a form of a slip-form device capable of easily removing or adding a form panel and a rising material in response to a change in circumference. And to provide a formwork structure.

[0008]

In order to achieve the above object, the mold of the slip-form device of the present invention has a predetermined backing material fixed to the back surface of the mold panel as described in claim 1. The formwork panels and the uprising members are configured to be detachable from each other.

Further, the form of the slip foam device of the present invention is such that the form panels of claim 1 and the uprising members are connected to each other by bolt joining.

Further, the mold of the slip-form device of the present invention is formed by a box truss of the upholstery material of claim 1.

Further, in the formwork structure of the slip-form device of the present invention, as described in claim 4, a predetermined repellent material is fixed to the back surface of the formwork panel, and the formwork panels are joined together, and the rebel material is relieved. It is provided with a mold frame configured to be detachable from each other, and a free panel in which a pair of claws that can slidably sandwich the mold frame are provided on the back side of the substrate so as to face each other and project.

In the slip foam apparatus 1 as described above, while the wall body of the tower-shaped structure 2 is constructed by placing concrete between the facing molds 4 provided below the yoke 3, the wall body already constructed. Is used as a reaction force to raise the entire apparatus by a hydraulic jack and slide the formwork panel upward with respect to the wall body, whereby the wall body can be continuously constructed.

As shown in FIG. 1 (b), the tower-shaped structure 2 does not have a generally cylindrical shape, but 45 °, 135 °, and 2 °.
A convex semi-circular portion in the 25 ° and 315 ° directions (hereinafter referred to as the convex portion 15) and a concave arc portion in the 0 °, 90 °, 180 ° and 270 ° directions (hereinafter referred to as the concave portion 1).
6) are combined to form a so-called spool type.

Here, while the convex portion 15 has a constant wall length, the concave portion 16 has a gradually decreasing wall length, and as a whole, the peripheral length becomes shorter as it goes upward.

The mold 11 of the slip foam apparatus 1 of this embodiment is arranged on the outer wall of the recess 16 whose wall length is shortened, and is supported by the yoke 3 similarly to the mold 4.

As shown in FIG. 2, the formwork 11 is constructed by fixing a vent material 22 to the back side of the formwork panel 21 (the side on which concrete is not placed) by welding or the like.

The formwork panel 21 has its left and right edges bent at substantially right angles to form a bent portion 25.
Is provided with a bolt hole 23, the two formwork panels 21 are adjacent to each other such that their bent portions 25 contact each other, and a predetermined bolt is inserted into the bolt hole 23 and fastened, whereby the formwork panel is formed. 21 can be connected to each other.

The uprising member 22 is a box type truss made of a combination of mountain steel and the like, and a bolt hole 24 is provided on the lateral surface of the vertical member 26 of the truss.
The two upholstery members 22 are adjacent to each other so that the vertical members 26 thereof come into contact with each other, and a predetermined bolt is inserted into the bolt hole 24 and fastened, whereby the upholstery members 22 can be connected to each other. There is.

The free panel 31 is arranged along the design wall surface as shown in FIG. 3 and serves as a barrier plate 3 for the substrate 3.
A pair of claws 33, 33 are provided at one end of the two so as to project on the back side at positions facing each other.

As can be seen clearly in FIG. 4 (a), the claws 33, 33 are made of grooved steel 37 having a length corresponding to the thickness of the formwork panel 21, and are suspended by welding or the like at the upper and lower edges of the substrate 32. A grooved steel 38 of a predetermined length is fixed to the other end of the grooved steel 37 substantially parallel to the substrate 32 in the form of a cantilever, and is inserted between the grooved steel 38 and the substrate 32. The formed form panel 21 is slidably held in the left-right direction in FIG.

By mounting the upper claw 33 on the substrate 32 while shifting it upward, a play d in the height direction is formed between the upper frame 33 and the frame panel 21.
It is configured such that 1 can be rotated by a predetermined angle around the normal line direction of the panel surface while being sandwiched by the claws 33, 33.

Further, as shown in FIG. 3, at the other end of the substrate 32, an ordinary form frame 36 (for example, a form frame in which an H-shaped steel of a predetermined length curved and formed on the back surface of a metal foam is attached as an upholstery material). A mounting plate 34 for fixing the is attached via a hinge 35. As can be seen from FIG. 4 (b), the hinge 35 has two plates rotatably attached to the shaft center fixed to the substrate 32 and the mounting plate 34 by welding or the like. And are relatively rotatable about an axis.

Form 11 and free panel 3 of this embodiment
When the tower-shaped structure 2 is formed by using 1, the mold 11 is placed on the side of the concave portion 16 and the ordinary mold 36 is placed on the convex portion 1 as shown in FIG.
5 side, and the free panel 31 is provided with the convex portion 15 and the concave portion 16.
It is arranged at the inflection point 51 which is the boundary of Then, the form panel 21 of the form 11 is inserted between the pair of claws 33, 33 provided on the free panel 31 to be stacked on the substrate 32, and the mounting plate 34 hingedly joined to the substrate 32 is projected. It is fixed to the side mold 36.

Next, while raising the entire slipform apparatus, the convex-side mold frame 36 and the concave-side mold frame 11 are horizontally moved along the direction of the arrow in FIG. 5, but in the horizontal movement, The mold 36 and the mold 11 are brought relatively close to each other so that the wall length of the recess 16 becomes short.

As shown in FIG. 5, when the mold frame 36 on the convex side is moved relatively closer to the mold frame 11 on the concave side, the mold frame 11 is clamped by the claws 33, 33 of the free panel 31, Since it slides between 33 and 33 and enters the side of the substrate 32 by the amount of the relative movement, the mold 1
1. Loosen the bolts of the formwork panel 21 and the upholstery material 22 of No. 1 to separate from each adjacent portion, and remove the formwork.

In this way, the molds 36 and 11 are horizontally moved to predetermined positions while the leading molds 11 are successively extracted. As can be seen in FIG.
Among them, a normal mold 41 is provided in a portion where it is not necessary to remove the mold, and this is arranged at the end of the row of the mold 11.

As a result of the relative horizontal movement, the fitting angle between the two molds 36 and 11 tends to change upward, but the mold 36 on the convex side is hinged to the free panel 31. , Both formwork panels 36, 11 are
The relative rotation freely follows the angle change.

Further, as shown in FIG. 6, in the convex portion 15, when the slope of the mold 36 is changed in accordance with the change in the slope of the design wall surface, the mold near the inflection point is rotated around the normal direction of the panel surface. However, since a predetermined play d is provided between the pair of claws 33, 33 and the concave side mold frame 11,
The free panel 31 relatively rotates with a predetermined angle around the normal line direction of the panel surface while holding the formwork 11 therebetween.

On the other hand, when the circumference is long, the mold 11 may be added in the reverse order of the above. That is, when the mold 36 is relatively separated from the mold 11, new molds 11 are connected to the front mold 11 one after another before the leading mold 11 passes through the claws. By doing so, it is possible to cope with a change in circumference.

As described above, according to the formwork of the present embodiment, the formwork panels and the upholstery members are configured to be detachable from each other. When the panel needs to be removed or added in the middle of the process, it is possible to easily remove and add the formwork including the upholstery material.

Further, according to the formwork of this embodiment, the formwork panels are connected to each other and the uprising members are connected to each other via the bolts, so that they can be quickly attached and detached. This is a useful tool for slip-form construction, which has many time constraints.

Further, according to the formwork of this embodiment, since the upholstery member is formed by the box type truss, it is possible to reduce the weight of the formwork as a whole and to improve the workability. Further, it is possible to reduce the burden on the yoke that supports the form, the hydraulic jack that raises the form, and the support structure thereof. Furthermore, since the rigidity is increased by the truss structure, the shape of the designed wall surface is firmly held, and a highly accurate wall body can be formed.

In this embodiment, when the mold 36 on the convex side and the mold 11 on the concave side are moved relative to each other, the relative rotation of the two at the inflection point and the relative rotation about the panel normal line are not restricted. Although the hinge 35 is provided on the free panel 31 and the fixing position of the upper claw 33 is shifted upward,
When it is not necessary to consider such relative rotation, a free panel 61 as shown in FIG. 7 may be used and applied as shown in FIG.

In the case of such a structure, the relative movement between the mold 11 and the free panel 61 is limited to the left and right direction in FIG. Since the procedure for removing or adding the mold 11 is almost the same as the above-mentioned content, detailed description will be omitted here.
