DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork used in the construction of floor slabs in the construction of office buildings, condominiums and other buildings.

[0002]

2. Description of the Related Art Conventionally, this type of mold is, for example, 900 mm ×
A rectangular plate a having a regular size of 1800 mm was used, and the plate a was placed and set at the formation location of the floor slab as shown in FIG.

[0003]

According to this conventional formwork, the plate b corresponding to the pillar portion shown in FIG. 3 needs to be formed with the notch c at the portion of the pillar portion, and the pillar portion has each floor. In this case, it is necessary to prepare plates b having different cross-sectional areas and different areas of the cutouts c according to this, and the plates b of a fixed size having different areas of the cutouts c are used several times. The waste of the material is great and the transportation of these plates to the site is difficult, and the plate b of the notch c having an area corresponding to the cross-sectional area of the pillar portion is searched for when the formwork is set on the site. There was a problem that the work efficiency had to be lowered because it had to be set.

It is an object of the present invention to solve these problems and to provide a formwork plate for floor slab which reduces waste of material and improves work efficiency.

[0005]

In order to achieve this object, the present invention comprises a combination of a rectangular main plate having a predetermined size and an auxiliary plate obtained by dividing the main plate into a plurality of parts.

[0006]

In the floor slab formwork plate according to claim 1, since the auxiliary plate divided into a plurality of pieces together with the main plate of a predetermined size is prepared, the shape of the formwork plate can be changed according to the shape of the floor slab. It can be applied to a small area auxiliary plate, which saves material.

In the frame slab for floor slabs according to claim 2, since the notch portion corresponding to the pillar portion is formed in the corner portion of the auxiliary plate, even if the cross-sectional area of the pillar portion or the like differs on each floor The cutouts may be formed at the corners of the auxiliary plate, which facilitates manufacturing and saves material.

In the frame slab for floor slabs according to claim 3, since the surfaces of the main plate and the auxiliary plate are coated, the main plate and the auxiliary plate are easily dissociated from the concrete at the time of dismantling the mold, thus facilitating the dismantling. The main plate and the auxiliary plate are not damaged and the number of times of diversion increases.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS.

Reference numeral 1 denotes a main plate, and the main plate 1 is, for example, 180
It is made of wood such as veneer plywood having a fixed size of 0 mm × 600 mm, and 2 and 3 denote first and second auxiliary plates, and the first auxiliary plate 2 is, for example, 1100 mm × 600 mm veneer plywood. The second auxiliary plate 3 is made of wood such as plywood having a size of 700 mm × 600 mm. When the first auxiliary plate 2 and the second auxiliary plate 3 are lined up, the size of the main plate 1 is It was made to correspond to.

Further, the second auxiliary plate 2 has a notch 4 having a size corresponding to a pillar portion of a building at one corner thereof.

The main plate 1 and the first and second auxiliary plates 2,
No. 3 is coated on its entire surface with urethane or the like.

Next, a description will be given of a form set of a floor slab using the main plate 1 and the auxiliary plates 2 and 3 of the above embodiment.

First of all, as shown in FIG. 2, each main plate 1 is set at the formation portion of the floor slab surrounded by the pillar portion A and the wall portion B,
Next, at the corner of the pillar portion A, the second auxiliary plate 3 is set so that the cutout portion 4 of the second auxiliary plate 3 contacts the pillar portion A, and the second auxiliary plate 3 and the main plate 1 are set. The first auxiliary plate 2 is set at a position adjacent to and another position.

After that, several kinds of elongated rectangular booths 5 are set on the remaining unset portions of the main plate 1 and the auxiliary plates 2 and 3, and the setting of the formwork is completed.

In this embodiment, the size of the notch 4 of each second auxiliary plate 3 having a small area is changed even if the cross-sectional area of the pillar portion A becomes smaller as the height increases. do it.

[0017]

As described above, according to the present invention, since the rectangular main plate having a predetermined size and the auxiliary plate obtained by dividing the main plate into a plurality of parts are formed in combination, it is possible to form a mold suitable for the shape of the floor slab. If the shape of the plate is changed to a small area of the auxiliary plate, the material can be saved and it can be easily transported.Because the surfaces of these main plate and auxiliary plate are painted, the main plate and auxiliary plate can be removed when the formwork is disassembled. It has an effect that it can be easily separated from the concrete and thus can be easily dismantled, and that the main plate and the auxiliary plate are not damaged and the number of times of diversion is increased.
