Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a formwork material used in the construction of concrete structures, and more particularly to a formwork material that also serves as a finishing base.

Conventionally, in the construction of concrete structures, the formwork is dismantled after the concrete has hardened, and after the formwork is dismantled, mortar is applied to the concrete surface as a finishing base material, or a base board is attached. For this reason, there was a drawback in that not only the work of registering and cleaning up the formwork, but also the work of applying or attaching the finishing base material required a great deal of time and labor. Although it is conceivable to use the base board directly as a formwork material in order to eliminate such drawbacks, a large value in terms of strength cannot be expected from this base board alone.

The object of the present invention is to provide a formwork material that can be used as a finishing base and which can eliminate the drawbacks of the conventional methods as described above.

The invention will be explained below with reference to illustrated embodiments.

FIG. 1.2 shows a formwork material 1 which also serves as a finishing base according to the present invention, and the formwork material 1 includes a weir plate 2 and a finishing base plate 3. The weir plate 2 is made of a metal plate such as a keystone plate, and by bending this metal plate to have a concave cross section, a plurality of ribs 4 are provided on one side of the plate so as to protrude parallel to each other. This weir plate 2 only needs to have tensile strength, and a plastic plate, a ceramic plate, a wooden plate, etc. can also be used.

The finishing base plate 3 is made of, for example, a waterproof gypsum board certified as a legally flame-retardant material. It is fixed to the weir plate 2 by tapping screws 5 protruding into the ribs 4 or by a combination of adhesive and tapping screws, and a heat insulating space 6 is formed between the shear plate 2 and the finished base plate 3. . This heat insulating space 6 may be filled with a heat insulating material such as glass wool or urethane foam.

Next, a method of constructing a concrete wall will be described as an example of using the formwork material 1 as described above with reference to FIGS. 3 to 5.

Formwork material 1 is manufactured at a factory according to the formwork construction drawings,
When connecting a plurality of formwork materials 1, adjacent formwork materials 1 are butted against each other at their side walls in the thickness direction, as shown in one side of the formwork shown by A in FIG. A reinforcing rib 7 having a U-shaped cross section is welded to the weir plates 2 over the entire length. This work is done at the factory. Alternatively, reinforcing ribs 7 are welded in advance to the weir plate 2 of each formwork material 1 at the factory, as shown in formwork B on the other side, as shown by B, and these reinforcing ribs 7 are joined at the site as shown in Fig. 4. By connecting with metal fittings 8, a plurality of formwork materials 1 are connected. Further, at the connecting portion between the formworks A and B, a supporting member 9 having an M-shaped cross section is interposed between the reinforcing rib 7 and the finishing base plate 3. 10 in FIG. 3 indicates satsushi.

Formworks A and B as above are placed on the foundation concrete II,
Both sheathing plates 2 are erected so as to face each other with a gap corresponding to the thickness of the concrete wall formed between them, and as shown in FIG. Attach form tie 13 to. Reference numeral 14 denotes a butterpipe, and a curing plate 15 is interposed between the butterpipe and the finished base plate 3, and the gap between the form frame B is maintained by tightening the form ties 13.

Then, concrete 14 is placed in the gap between formworks A and B, and after it hardens, only the fastening materials such as form ties 13, batapipes 14, and curing plates 15 are removed, and concrete 14 is poured into the gap between formworks A and B. Then, apply the required finish to the finishing base & 3.

In the above description, an example was explained in which the formwork material 1 is used in the construction of a concrete wall, but it can also be used not only in the construction of a concrete wall but also in the construction of concrete columns, concrete floor slabs, etc.

As described above, this invention has a plurality of ribs protruding from the weir plate, and a finishing base plate is fixed to these ribs, so that such a finishing base-frame material can be used as a waste frame when constructing a concrete structure. By using it as a base, it is possible to eliminate the work of dismantling the formwork and the work of applying or installing the finishing base material, thereby saving on-site labor and shortening the construction period, reducing construction costs. Since it can be manufactured easily, accuracy can be improved, and since a heat insulating space is formed between the weir plate and the finished base plate, heat transfer inside and outside the structure is suppressed, resulting in energy savings. It has the following effects:
