And an intermediate column member 10 disposed between the member 9.

Then, the height direction is adjusted by these members 8, 9, and 10.

More specifically, the column capital member 8 is mainly composed of a short prismatic body having a rectangular hollow portion 12, and a so-called insertion portion for receiving a projection member of a column base member 9 described later is formed in the hollow portion 12. A wedge insertion hole 13 through which a wedge body to be described later is inserted is formed on both sides of the "longitudinal connection tool" with the mounting portion and the projection member. Further, below the wedge insertion hole 13 of the stigma member 8, on both sides or one side (both sides in the present embodiment) of the side portion, there are provided a plurality of screw holes 15 into which the tightening screws 14 are screwed (in this embodiment). 2) is established. A mounting member 17 that abuts against the side plate 1 is stretched on the upper end side of the stigma member 8, and a hole formed in the mounting member 17 is provided.
A mounting screw 18 is inserted through 17a.
The capital member 8 is attached to the side plate 1 by screwing. A nail can be used instead of the mounting screw 18. Note that the mounting member 17 can be omitted and the stigma member 8 can be mounted on the side plate 1 with an adhesive.

The column base member 9 is mainly a short prismatic body having a rectangular hollow portion 20 like the column capital member 8, and a screw hole 22 in which a tightening screw 21 is screwed is opened in a side portion thereof. The column base member 9 is attached to the side plate 1 by a mounting screw 24 through a hole 23a.

The column base member 9 further has a projection member 26 attached to a lower portion of the hollow portion 20 in a strongly fitted state. The protruding member 26 protrudes from the lower side 1b of the side plate 1 and is inserted into the hollow portion 12 above the supporting column 2 of the other form panel K located below the main form panel K, that is, the fitting portion in close contact therewith. You. The projection member 26 is provided with a wedge insertion hole 27 along the longitudinal direction of the side plate 1, in which the wedge body is inserted in correspondence with the wedge insertion hole 13 of the capital member 8.

FIG. 4 shows an example of a vertical connector joined by a wedge body. That is, after the projection member 26 is inserted into the fitting insertion portion 12 of the column 2, the wedge insertion hole of the telescopic column 2 and the projection member 26 are inserted.
The wedge body 28 is inserted into the holes 13 and 27, and the engaging element 29 is inserted into the hole 28a to fix the wedge body 28. Thereby, the protrusion member
26 is prevented from coming out of the column member 8 of the telescopic strut 2,
The upper and lower form panels K are firmly connected to each other.

The intermediate column member 10 is a hollow portion of the capital member 8 and the leg member 9.
Although the cross section is smaller than the cross section of the hollow portions 12 and 20 in order to facilitate the insertion into the insides 12 and 20, the rigidity is sufficiently maintained. In addition, a material that can be appropriately cut, for example, wood or a synthetic resin is used, but a material made of metal is not excluded.

In the longitudinal direction, the telescopic strut 2 is installed at a position L / 4 from both ends of the side plate 1 in the longitudinal direction of the side plate 1 having the length L. Not limited. According to this basic arrangement, the form panels K can be arranged vertically in a staggered manner.

The crosspiece member 3 has a fixed length and a mode in which the length can be appropriately changed.

Thus, in this embodiment, the telescopic strut 2 and the crosspiece member 3 are rigidly joined to form the frame 4. As long as it is rigidly joined, another mode, for example, a mode in which it is directly fixed to the telescopic strut 2 by welding or the like without using an angle material can be adopted.

The separator 5 is formed on the opposing form panels K.
It is disposed between the upper cross members 3 (see FIGS. 1 and 2). More specifically, the separator 5 includes a rod body 5a inserted into a hole 33 formed in the crosspiece member 3 and a hole 34 formed in the side plate 1, and threaded portions at both ends of the rod body 5a. It comprises a nut 5c screwed into 5b, and a spacer 5d through which the rod body 5a is inserted and abuts on the side plate 1. In the present embodiment, the backing plate 35 is interposed between the cross bar member 3 and the nut 5c, but may be omitted. Thus, by determining the distance between the two spacers 5d and tightening the nut 5c, the mutually opposing form panels K are positioned.

The cross beam member 6 is installed between the telescopic columns 2 in the manner of the cross bar member 3 via the angle members 30 attached to the telescopic columns 2 of the adjacent form panels K. That is, at both ends of the cross beam member 6, bolt insertion holes 6a are drilled corresponding to the bolt insertion holes 30a drilled in the angle member 30, and these holes 6a, 30a
Then, a fastening tool 31 is inserted into the cross member 6 to fasten the horizontal beam member 6. However,
Since the cross beam member 6 is detachable, a permanent rigid connection is not taken.

The feature of the formwork panel K of this embodiment is that, as described above, the frame 4 is composed of the telescopic strut 2 and the crosspiece member 3, and the telescopic strut 2 is That is, the length can be adjusted in accordance with the height H. Furthermore, when the cross bar 3 is made of a material that can be cut as appropriate, it can appropriately correspond to the width L of the side plate 1 and, consequently, the interval between the extendable columns 2.

The form panel K having the above-described configuration is used as described below by utilizing the features of the configuration.

That is, in the construction of a concrete structure using the formwork panel K, the aspect (case 1) used over the entire height of the concrete structure is applied to the remaining portion when the standard formwork panel is used. (Case 2) and the above-described combined mode (Case 3). Hereinafter, cases 1 and 2 will be described.

Case 1 The height of the concrete structure to be constructed is appropriately divided (usually equally), and the side plate 1 is cut to the height. Then, an intermediate column member 10 having an appropriate length is selected or cut in accordance with the height of the side plate 1, and the intermediate column member 10 is cut.

Also, holes 33 and 34 for the separator 5 are opened. In addition,
In the lowermost form panel K, the projection member 26 is omitted.

In the assembling work, after the lowermost form panel K is fixed on the foundation portion, the upper form panel K is sequentially stacked on the form panel K by using a vertical connector. That is, the projection members 26 of the upper frame panel K are inserted into the insertion portions 12 of the lower frame panel K, and the wedge insertion holes 13 and 2 are inserted.
7. A wedge body 28 is inserted into 7, and an engaging element 29 is driven into a hole 28d of the wedge body 28. Further, the form panels K adjacent to each other in the horizontal direction are connected by the cross beam member 6.

The spaced form panels K are held at predetermined intervals by the separator 5.

Concrete is poured into the thus assembled formwork.

The fluid pressure of the concrete that has not yet solidified presses the formwork outward, but the projecting member 26 of the vertical connection between the formwork panels K acts as a resistor against the vertical bulging pressure,
In addition, the horizontal beam member 6 between the form panels K acts as a resistor against the bulging pressure in the horizontal direction, and maintains the form.

When the concrete is solidified, the form panel K is removed. This removal operation can be easily performed by removing the wedge 28 of the vertical connecting member, removing the cross beam member 6, and then pulling the form panel K upward. .

Case 2 A large form of a formwork is constructed using a standard form panel J prepared in advance. Then, when reaching the uppermost stage, if the part cannot be matched with the standard panel J, the formwork panel K is applied.

In other words, there are two cases where the portion exceeds or is less than the height of the standard form panel J. In either case, the side plate 1 is cut to that size. Then, the length of the intermediate column member 10 of the telescopic strut 2 is adjusted in the manner described for the case 1 so as to conform to this, and the telescopic member 2 is fixed to the side plate 1. In addition, the crosspiece member 3 is fixed.

In this way, the form panel K is prepared and installed on the form assembled by the standard panel J.
The installation of the separator 5 is also performed according to the above.

In this embodiment, the construction speed is high because standard panels are used.

In this case, in the formwork panel K, the wedge insertion hole 13 of the stigma member 8 of the telescopic strut 2 is omitted, so that the stigma member 8 is shortened by that amount, and the upper side 1a of the side plate 1 is also shown in FIG.
