Description

[Detailed Description of the Invention] The present invention relates to an inner formwork material that is used by being laid in an outer formwork for forming aggregate block panels made of concrete.

In FIG. 5, the upper surface of the panel is formed into a group of small blocks 8 that appear to be divided by the formation of deep ■-shaped joint dividing grooves 12, and the bottom surface of the panel is connected by a connecting layer 10 extending over the entire panel, and the above-mentioned joints are formed. The assembled block panel 7 is shown in which each small block is made breakable at the weak joint 9 at the bottom of the groove 12.

This aggregate block panel 7 is widely used as a panel to be laid on uneven ground, but when molding the cut aggregate block panel in concrete, if metal formwork is used, it is difficult to use metal formwork, which is a heavy object each time it is formed and demolded. Reversing the formwork requires hard labor, and it is necessary to hit the mold with a hammer to encourage it to come out. Even if it is taken out, the product may be damaged, or the surface may peel or become rough, resulting in a beautiful finished surface. I couldn't get it.

Also, wooden formwork has the disadvantage that it cannot withstand repeated use.
In addition, molding materials such as concrete adhere firmly to the surface, making it difficult to manage the formwork such as removing it, resulting in rough skin and poor quality of the product, as well as the drawback that sufficient precision cannot be required. .

The present invention eliminates the above-mentioned drawbacks by integrally molding the surface shape of the block panel by using an inner form frame material and an outer form frame made of synthetic resin film.
The purpose is to improve the demolding effect and molding finishing effect.

The present invention will be described below based on an illustrated embodiment.

The inner frame material 1 is made of a film made of synthetic resin such as vinyl chloride or polypropylene and integrally molded by vacuum forming, and has a thickness that has an appropriate shape-retaining effect.

The inner formwork material 1 has a bottom part 3 that is closely supported on the inner bottom surface of the outer formwork 6 and a bottom part 3 that is closely supported on the inner peripheral surface of the outer formwork 6.
It is cut from the frame part 2 raised from the periphery.

On the inner bottom surface of the inner form frame material 1, that is, on the upper surface of the bottom surface portion 3, a joint molding portion 4 is raised so as to intersect vertically and horizontally integrally with the frame portion 2 and the bottom surface portion 3, and is surrounded by the frame portion 2 and the bottom surface portion 3. A bottomed small molding chamber group 5 surrounded by each joint molding section 4 is defined in the inner space of the inner form frame material, and each unit small block is formed in the small molding chamber group 5 surrounded by the joint molding section 4. The configuration is such that 8 is molded.

Each joint molded portion 4 has a deep inverted ■-shaped cross section.

Further, as shown in the figure, the joint molded part 4 is arranged so as to be lower than the height of the frame part 2, and the frame part 2 is placed above the joint molded part 4.
An upper molding space 11 is formed that spans the entire opening area of the small molding chamber group 5 surrounded by , and the bottom connecting layer 10 can be molded over the entire area of the collective block panel 7 in the upper molding space 11. , a weak joint 9 is formed at the bottom of the joint groove 12 by the lower wedge-shaped joint forming section 4 .

Furthermore, a flange 2' is made to project laterally around the upper end of the frame 2, and is configured to cover the upper end of the opening of the outer frame 6.

As shown in FIG. 3, the inner form frame material 1 is fitted into an outer form frame 6 having the same shape as the inner form frame material 1 and brought into close contact with the inner form frame material 1 to form a form for forming the block panel 7. .

In this figure, a rigid joint forming support part 4' that fits into the joint hole part 4 of the inner form frame material 1 is formed on the inner bottom surface of the outer form frame 6 to ensure that the shape of the inner form material 1 is maintained. Indicates the case where

After the inner formwork material 1 is set in the outer formwork 6 in this way, concrete or the like is poured into the inner formwork material 1, and the above-mentioned small molding chamber group 5 is formed.
Then, the molding space 11 is filled with the same concrete, etc., and after hardening, the inner formwork 1 is attached from the outer formwork 6 while the block panel 7 is removed, and this is reversed to improve the flexibility and peeling effect of the inner formwork material 1. This can be easily peeled off and removed from the block panel 7 to complete the work.

In this case, the outer formwork 6 is not limited to a metal formwork, but may also be a wood formwork, and an outer formwork 6' without a joint forming support part 4' as shown in FIG. 4 is used. You can also do that.

According to the present invention, the block panel 7 is removed from the outer formwork 6゜6' together with the inner formwork material 1, and after being turned over, the inner formwork material is easily removed due to the flexibility and peelability of the synthetic resin. It is possible to perform demolding work by peeling it off, and there is no difficulty in demolding work as in the past.

In particular, the flange 2' is extended from the upper end of the frame 2 of the inner frame material 1,
Since it is configured so that the upper end of the opening of the outer formwork 6°6' can be covered, it is possible to effectively prevent conch notebook from entering the back side of the inner formwork when pouring concrete, etc.
In addition, the inner form 1 can be removed from the outer forms 6, 6' very easily by gripping the flange 2', and the inner form 1 can be easily peeled off from the panel using the flange.

It is also possible to attach the inner formwork material 1 as it is as a protective member to the panel 7 and remove it on site.

In addition, due to the adhesion effect of the synthetic resin film, it is possible to create a beautiful mirror finish on the gaps between the joint grooves 12 and on the entire surface, and there is no roughening of the surface of the conventional products, and the accuracy of the outer frame is insufficient. It also has the advantage of being able to provide highly accurate formwork.

Honnai formwork material is extremely suitable as a disposable formwork,
It can be expected to streamline the concrete molding of the above-mentioned aggregated block panels and improve work efficiency.
