Description

Detailed Description of the Invention

[0001]

[Industrial application] By using expanded polystyrene as a formwork for the concrete casting formwork used in the construction process of reinforced concrete and steel-framed concrete structures, the construction process is shortened and there is a chronic shortage at present. It also reduces the number of formwork specialists who are working on it, and also helps reuse the foamed polystyrene, which is a problem as waste that is difficult to dispose of.

2. Description of the Related Art Conventionally, a building structure made of reinforced concrete or steel reinforced concrete is constructed by using a concrete panel before placing concrete, forming a predetermined shape by a formwork technician, adding concrete, adapting to the shape, and drying. A concrete frame is constructed by removing the concrete panel.

[0003]

[Problems to be Solved by the Invention]

(1) Concrete panels are used for the building structure of reinforced concrete and steel-framed concrete, and a formwork specialist forms a predetermined shape and inputs concrete to build a concrete skeleton. Indicates a difficult situation. The present invention addresses such a shortage of professional workers.

(2) As a global problem, the destruction of nature by cutting down forest resources has been regarded as a problem, but the decrease in forest resources is expensive due to the steep rise in timber products.
Concrete panels are timber products that are similar to that,
In this way, it aims to improve the effects of protection and cultivation of limited forest resources and reduce construction costs.

(3) Foamed polystyrene used as a raw material of the present invention is now a problem as the most difficult dust to be treated, but by using it as a building, its generation cycle will be significantly delayed. It is a thing.

[0006]

As described above, the concrete pouring formwork according to the present invention uses foamed styrene as a raw material and solves the problems by the following means.

Due to the nature of foamed polystyrene, it is easy to process and mold, and it is light and excellent in heat retention. By utilizing this property and using a foamed polystyrene molded body as a concrete pouring form material, it is possible to easily manufacture a predetermined shaped body by mass production.

The foamed polystyrene is lightweight and easy to work and form, and the concrete placing form according to the present invention has a simple assembling shape and easy to unify parts.
Furthermore, after it is used as a formwork for concrete pouring, it is used as a heat insulator and a dew condensation preventive material for its reinforced concrete, steel bars and steel-framed concrete structures. This will reduce the construction work and shorten the construction process to deal with the chronic shortage of formwork specialists.

In addition, since concrete panels are not used, it is possible to indirectly prevent the natural destruction caused by the felling of forest resources, enhance the effect of protecting and nurturing forest resources, and protect the nature, which is regarded as a problem worldwide. It is something we are considering.

First Embodiment The present invention will be described with reference to the drawings. 1 is a partial side sectional view of an embodiment according to the present invention, FIG. 2 is a plan view, FIG. 3 is a bottom view, and FIG. 4 is a partial side sectional view and an assembly view.

Foamed polystyrene mold body 1 according to the present invention
As shown in FIG. 4, the outer-wall-side mold forming body 3 and the inner-wall-side mold forming body 4 are formed by a separator 6 into an H-shape in which the upper and lower portions are in the same interval.

Outer wall side mold body 3 and inner wall side mold body 4
A convex projection insertion portion 11 is formed on the upper surface of the upper part of the above, and a concave projection fixing portion 21 is formed on the bottom surface of the lower portion. The convex projection insertion portion 11 is inserted into the concave projection fixing portion 21 and fixed to a predetermined portion. Stack to height.

Outer wall side mold form 3 and inner wall side form mold 4
And the frame is formed by reinforcing bars or steel frames at the points where the concrete frame is constructed. When the skeleton is formed, the outer wall side mold forming body 3 and the inner wall side form forming body 4 are stacked up to a predetermined height, and concrete is poured to construct a concrete skeleton.

Further, on the upper surface of the upper part of the outer wall side mold forming body 3 and the inner wall side mold forming body 4, as a mechanism for preventing the frame from slipping, a mold assembly setting guide 12 showing a convex shape and a lower part bottom surface part. A mold frame assembly setting guide receiving groove 22 having a concave shape is formed so as to be continuous with the convex projection insertion portion 11 and the concave projection fixing portion 21.

Further, a concrete skeleton close contact margin 43 is formed on the concrete skeleton joint surface 44, which is the inside of the outer wall side mold slab 3 and the inner wall side mold slab 4, so that the outer wall side mold is formed from the concrete skeleton thus constructed. The frame molded body 3 and the inner wall side frame molded body 4 are taken into consideration so as not to be easily separated.

EFFECTS OF THE INVENTION The concrete pouring form according to the present invention is constructed as described above, and since it uses foamed polystyrene as a raw material, it is easy to process and mold, and is light and has excellent heat retention. There is.

Since the polystyrene foam is easy to process and mold, it is possible to easily produce a predetermined shape body by mass production. Furthermore, since the assembly shape is light and the parts can be easily standardized, it does not require the work of a formwork specialist to assemble it. It will be resolved.

Further, since it is also excellent in heat retaining property, it can be used as a heat retaining material and a dew condensation preventing material for the siding, rebar, and steel-framed concrete structures after being used as a concrete placing formwork. The trouble of removing is unnecessary,
This has the effect of reducing personnel costs and shortening the construction process.

Foamed polystyrene is a problem as the most difficult waste to treat as industrial waste. Annual production of about 35
Out of 10,000 tons, thick foam polystyrene is about 1 for packing
About 60,000 tons are used as food bags for thin foam polystyrene, and about 100,000 tons are discarded as garbage. INDUSTRIAL APPLICABILITY The present invention is useful not only for its reuse, but also for significantly reducing the generation cycle of dust by using it as a building.

Nowadays, as a global problem, natural destruction due to logging of forest resources is regarded as a problem. In the present invention, however, since concrete panels, which are wood products, are not used, it is necessary to protect forest resources. It also takes into consideration the conservation of nature, which has enhanced the effect of breeding.
