It is possible to form the construction surface in a flat state that does not occur.

A flat tie 4 is fitted to the contact surfaces of the panel forms 2 arranged to the left and the right. As shown in FIG. 2, a plurality of the flat ties 4 are fitted in a posture penetrating between the inner wall formwork F1 and the outer wall formwork F2.

The flat tie 4 may have a constant width, as shown in FIG. 5, and may have a conventional structure having a length corresponding to the distance between the two formwork bodies F1 and F2.

The flat tie (4) is sandwiched between the facing formwork (F1, F2) through the operation of fixing both ends, as shown in Figure 2 the wall (W) construction as possible to the formwork (F1, It serves to maintain the interval of F2).

In addition, normal fastening holes H1 are formed at both ends of the flat tie 4 to fix the molds F1 and F2 as shown in FIGS. 2 and 5.

On the other hand, each panel form (2) has a fixing bracket (6) for supporting the end of the flat tie 4 in a state wrapped around it.

A plurality of fixing brackets 6 are respectively located in correspondence to the point where the flat tie 4 is fitted at both ends of the outer side surface T of the panel form 2 (see FIG. 2).

Each fixing bracket 6 is connected to two fixing parts B1 and two fixing parts B1 on the outer side surface T of each panel form 2 as shown in FIGS. 1 and 6. It may be made of a connecting portion (B2).

The fixing bracket 6 may use a metal plate, and welded integrally to one side of the panel form 2 or may be fastened and fixed by a conventional method using bolts although not shown in the drawing.

And, on one side of each fixing portion (B1) is formed a support groove (H2) having a size that can accommodate the flat tie (4), the fastening groove penetrating in the direction crossing the support groove (H2) ( H3).

Each of the support grooves H2 extends from the fixing part B1 side to the thickness surface of each panel form 2 as shown in FIG. 5.

That is, the support groove (H2) may be fitted with a flat tie (4) so that the gap does not occur between the fixing portion (B1) of the fixing bracket (6) facing each other in the panel form (2) adjacent to each other.

Each of the fixing brackets 6 may be supported by overlapping and wrapping the end portions of the flat tie 4 fitted between the panel forms 2 in the facing formwork F1 and F2.

At this time, the fastening hole H1 of the flat tie 4 is located at a point corresponding to the fastening holes H3 of the fixing part B1.

Each connecting portion B2 is attached to and fixed in a direction crossing between the edges facing each of the panel forms 2 to support the two fixing portions B1 and to act on each panel form 2. It acts as a kind of rib that can suppress surface deformation by load or external force.

Then, two fixing parts B1 facing each other with the flat tie 4 interposed therebetween are fastened and fixed by the pin members 8, respectively.

The pin member 8 may be composed of a first fixing pin (P1) and a second fixing pin (P2) as shown in FIG.

The first fixing pin P1 is inserted into the fastening hole H3 of the opposite fixing part B1 and the fastening hole H1 of the flat tie 4, and then fastened. Fasten the second fixing pin (P2) to the end.

The first fixing pin (P1) and the second fixing pin (P2) may use a fixing pin having a conventional wedge shape used in the formwork, the locking groove (H4) for fitting the catch contact These are formed, respectively.

Therefore, as described above, the panel members 2 for fastening the pin members 8 to the respective points to form the molds F1 and F2 are connected to each other and the gaps between the mold members F1 and F2 are maintained. The flat tie 4 can be fastened and fixed together.

In particular, such a structure can be fixed to the panel form (2) and the flat tie (4) at a time by using the pin member (8) it is easy to install or dismantle the form (F1, F2) This can reduce the time required.

In the above-described embodiment, forming the integrated panel foam 2 from one aluminum plate body extruded is shown in the description and drawings as an example, but is not limited thereto.

For example, as shown in Figure 8 it can be formed integrally by fixing a plurality of fixing brackets 6 in the up and down direction in a state in which two or more aluminum plate (A) is connected to the left and right.

Each of the plate bodies (A) may form a panel form (2) by attaching the fixing bracket (6) in a state of fitting them by forming a common protrusion and groove as shown in Figure 9 when connecting two or more.

And, the formwork panel form according to the embodiment of the present invention can be made to further include a fixing member 10 for attaching and fixing to the upper and lower points of each panel form (2) as shown in FIG.

Each fixing member 10 may be composed of an upper fixture (G1) and a lower fixture (G2).

The fixtures (G1, G2) is made of a bracket shape having a size that can cover the upper and lower edges of each panel form (2), as shown in Figure 10, the top, bottom of each panel form (2) Welding may be fixed to the side in the same posture as in the drawings or fixed with a fastening member such as a bolt.

The upper fixture G1 supports the slab formwork F3 as shown in FIG. 11 when the panel foams 2 are arranged on the ground to form the inner wall and outer wall formwork F1 and F2. Can be fixed with the connection.

In addition, the lower fixture G2 may be connected to a general support angle F4 installed on the bottom surface to support each of the dies F1 and F2 on the ground, as shown in FIG. 12.

That is, the two fasteners G1 and G2 may stably fix each panel form 2 when each of the formwork bodies F1 and F2 is installed on the ground.
