Next, a foam tie N for reinforcing the form will be described with reference to FIGS. 12 to 14.

The foam tie N has a flanged threaded rod n2 having a flange n1 at its tip, and a holding metal fitting n3 for holding the lateral end thick 6b. A screw shaft s4 screwed into the screw hole s2 'of the spacer cylinder s2 constituting the spacer S is screwed into the end of the flanged screw rod n2 on the flange n1 side.
1'is formed. Further, the holding metal fitting n3 has a locking piece n4 formed by bending both ends of a rectangular metal plate material in a substantially vertical direction in the same direction, and at the center portion n5 of the holding metal fitting n3, A through hole n6 into which the flanged screw rod n2 can be inserted is formed.

As an example, in order to reinforce the barrier plates 4 and 4, screwing into the screw hole s2 'of the spacer cylinder s2 protruding from the through hole 5 formed in the assembled barrier plates 4 and 4. The combined screw shaft s4 is screwed into the screw hole n1 ′ formed in the flanged screw rod n2 of the form tie N, and the flanged screw rod n2 is attached to the spacer S.

The threaded rod with flange n2 is inserted into the through hole n6 of No. 3. At this time, the locking pieces n4 of the holding metal fittings n3 are configured to abut the upper and lower wall surfaces 6b1 and 6b2 of the two lateral thick ends 6b, respectively. Then, a nut n7 is screwed onto the threaded rod with flange n2, and two horizontal ends are provided side by side by the holding metal fitting n3 and the vertical end thicker 6a vertically attached to the dam plate 4. At the same time as sandwiching the thick thickness 6b, the vertical thickness 6a is pressed against the dam plate 4 by the lateral thickness 6b. In this way, the support of the barrier plate 4 is further reinforced. Since the assembly fitting K is no longer needed after the horizontal end thickness 6b is provided, the assembly fitting K is removed after the horizontal end thickness 6b is provided and before the fresh concrete is poured. You can also

FIG. 15 shows an example in which an additional vertical end thickness 6a1 is further provided between the vertical end thicknesses 6a arranged as described above. As an example, in FIG. 15, the assembly metal fitting K4 is attached so as to straddle the second weir plate 4 ′ and the third weir plate 4 ″, and is attached to the recess K ′ of the assembly metal fixture K4. , An example in which an additional vertical end thicker 6a1 is inserted and the formwork is further reinforced is shown.

In a space formed between the dam plates 4 constituting the formwork assembled as described above, as is known,
Fill with fresh concrete. Then, after the ready-mixed concrete is hardened, the assembling metal fitting K, the vertical end thickness 6a, the horizontal end thickness 6b, and the additional vertical end thickness 6a1 are removed, and the dam plate 4 is removed.

When a wood-based cement board (wood wool cement board or wood chip cement board) composed of wood material such as wood wool, wood chips or wood chips and cement is used as the dam board 4 described above, The cement liquid of the fresh concrete filled in between penetrates into the wood-based cement board, and after the ready-mixed concrete hardens, the weir board of the wood-based cement board and the concrete have good adhesion. It is not necessary to peel off the weir board of the system cement board. In particular, since the wood-based cement board has a large holding power for fasteners such as screws and nails, and also has high heat insulation performance and sound insulation performance, it is preferable to leave the weir board as the wood-based cement board as it is. .

Particularly, it is preferable to use a wood wool cement board as the wood-based cement board, and in particular, a hard wood wool cement board having a bulk specific gravity of 0.7 or more and having a large bending strength and breaking strength is used. With this, the holding force, the bending strength, and the shear strength with respect to fasteners such as screws and nails are remarkably improved.

It can also be configured to perform leveling of.

As described above, the weir plates 4 juxtaposed in the horizontal and vertical directions are connected by the assembly metal fitting K having the U-shaped portion k1, and the vertical end is formed in the recess K'of the assembly metal fitting K. Since the thick end 6a is inserted, and the lateral end thick end 6b is then arranged by the form tie N to assemble the formwork, square members are attached around the four barrier plates, and then the barrier plates are connected. Compared to the conventional formwork assembling method in which the vertical and horizontal ends are attached to the weir plate, the work of assembling the lumber to the weir plate 4 is unnecessary in the formwork assembling method of the present invention. In addition, the thick vertical edge 6a is simply
Since it is only inserted into the concave portion K ′, the time required for the work of assembling the mold can be shortened and the cost of the dam plate 4 can be reduced.

2, one weir plate 4 and one weir plate 4 forming a corner
a, 4a and the weir plate 4 arranged side by side on the one weir plate 4 disposed on the pier member B2 are arranged so that their vertical end faces and upper end faces are aligned and connected by the assembly metal fitting K. The level of the dam plate 4 forming the frame can be accurately set.

After leveling the dam plates 4a, 4a forming the corners by using the level adjusting members H1, H2, H3 attached to the dam plates 4a, 4a forming the corners, or After leveling the dam plate 4 by using the level adjusting member H attached to one dam plate 4 arranged on the dam member B2, the dam plates 4a and 4a forming the corners and the dam member B
2, one weir plate 4 and one weir plate 4 forming a corner
a, 4a and the weir plate 4 arranged side by side on the one weir plate 4 arranged on the pier member B2, their vertical end faces and upper end faces are aligned and connected by the assembly metal fitting K, and then the corners are The level adjusting members H attached to the weir plates 4 a and 4 a and the one weir plate 4 arranged in parallel with the weir plate 4 that are arranged on the dam member B2.
Since the leveling is performed by the above method, the leveling of the dam plate 4 forming the formwork can be performed more accurately.

[0040]

Since the present invention has the constitution described above, it has the following effects.

Compared to the conventional formwork assembling method in which square members are attached to the four periphery of the weir plate, and then the weir plates are connected and attached to the weir plate at the vertical and horizontal ends. In the formwork assembling method of the present invention, it is not necessary to attach a square member to the dam plate, and the vertical end thickness is simply inserted into the recess of the assembly fitting. The required time can be shortened and the cost of the barrier plate can be reduced.
