In particular, in the case of forming a hollow part having a square hollow portion in a concrete structure, for example, a hollow block concrete block, a square hollow concrete pier, a square concrete chimney, a caisson, or the like, While assembling the inner formwork, fix the inner formwork by extending the cutting beam between the opposing forms, and when removing the concrete after casting, knock down the cutting beam and cast the inner formwork in concrete. They are forcibly stripped from the surface. These steps are repeated as many times as the concrete is cast, and the work is complicated and the efficiency is not improved.

Prepare a frame body with a corrugated sheet attached to the four outer peripheral surfaces of the frame, attach a form panel on the corrugated sheet to form an inner form, and use the elastic deformation of the corrugated sheet after placing concrete. To pull out the frame, and then pull out the form panel. This is an easy to assemble and remove the mold, and can be used repeatedly by attaching the mold panel to the frame again, which has been effective. However, it is intended to further improve this. .

The support rod 2 is attached to the drum 1 so that the rod 2 can be raised and lowered. The supporting rod 2 connected to the illustrated frame 1 is formed so as to fall down from a standing state by a hinge pin 3, and three such supporting rods 2 are provided at predetermined intervals in the vertical direction. The formwork panel 4 can be fixed to the tip of the support rod 2, and a mounting bracket 5 is provided at the tip of the support rod 2 in the figure, and the formwork panel 4 is fixed here. I can do it.

なく定間隔に位置決めすることができる。The formwork panel 4 can be made of wood, metal, synthetic resin, or the like. If it is made of wood or synthetic resin, the formwork panel 4 is fixed to the mounting bracket 5 with bolts, nuts, or nails. In the case of the product, it is preferable that the mounting bracket 5 is fixed to the mounting bracket 5 by bolts, nuts, welding or the like. FIG.
In this case, the support rods 2 of the inner form support 6 are formed in four directions from the frame 1 so that the form panel 4 can be attached to each support rod 2. . Thus, the facing form panels 4 can be positioned at regular intervals without using a form width determining bolt (separ bolt) as in the related art.

形成することができる。The inner formwork 7 in which the formwork panel 4 is mounted on the inner formwork support 6 is held upright by pulling up the distal end of the support rod 2 with a turn buckle 8 or another pulling tool (FIG. 3). 4). At this time, the gap formed between the adjacent form panels hits the four corners of the inner form 7 and is closed by the corner panel 11. The corner panel 11 can be formed into an L-shaped, dish-shaped, arc-shaped or other shape in accordance with the corner shape of the hollow portion of the concrete structure to be molded.

すことができる。The corner panel 11 can be formed of a steel plate, plastic or other strong material. In this case, the corner panel 11 is temporarily attached to the form panel with an adhesive tape, or when the form panel is made of wood. If it is nailed or temporarily attached to a small portion, the inner mold can be easily detached from the form panel when the inner mold described later is pulled out and removed. In addition, if a thin steel plate is used, it can be fixed to the formwork panel with screws, bolts, etc. There is a slight gap between the casting surface and the casting surface, which can be removed together with the form panel.

ト金具が不要となって便利である。The inner frame 7 is positioned by fixing an upper portion of the frame 1 to a positioning pipe 12 with a clamp 13. The fixing by the clamp may also be used to fix the support rod. it can. If the outer mold (not shown) is also fixed by using the positioning pipe 12, a separate metal fitting between the inner and outer molds is unnecessary as in the conventional case, which is convenient.

む。When the positioning of the inner mold frame and the outer mold frame has been completed, a concrete 14 is cast between the two mold frames and curing is performed for a predetermined period (FIGS. 3 and 4). When the concrete has hardened, as shown in FIGS. 5 and 6, the turnbuckle 8 fixing the support rod 2 of the inner mold frame 7 is removed, and the frame 1 is further removed.
The clamp 13 fixed to the positioning pipe 12 is removed, and the wire 1 is connected to the hook 9 or the like provided with the frame 1.
Then, the inner mold 7 is hung upward by a winch or the like.

A slight gap 19 is formed between the inner mold 7 and the inner mold 7 so that the inner mold can be slightly moved upward. Thereafter, the entire mold can be pulled up lightly and the inner mold 7 can be removed. Since the outer frame can be easily removed from the outside, a concrete structure having a hollow portion can be easily and reliably obtained. Since the inner mold can be used repeatedly in the same manner as described above, there is no trouble in forming the mold, and the inner mold can be used easily and economically.

Square block 22 having a plurality of hollow portions 20 such as 2
Can be easily manufactured. This inner mold is particularly effective when efficiently manufacturing a hollow part to be formed, in which the hollow part to be formed is relatively small and work in the hollow is difficult, but is not limited to such a thing, such as a caisson. Similarly, those having a large hollow portion can be easily formed. In addition, although the embodiment in which the inner mold is used in a vertical orientation has been described above, the inner mold can be used in a horizontal orientation.

A concrete structure can be manufactured without using a separator between the outer forms. In addition, when removing the mold, the inner mold can be removed together with the mold panel by a relatively light operation by pulling the inner mold upward, etc., the structure is simple, the assembly is easy, and the disposal is easy. It is economical to use because it does not produce any trouble and hardly causes breakdown. In addition, not only the above-described square hollow hole, but also a hollow hole having a cross section of a triangle, a polygon, an ellipse, or the like can be similarly manufactured in accordance with the above.
