Description

[Detailed description of the invention] This invention uses alkali-resistant glass fiber reinforced concrete (hereinafter referred to as GRC) to provide a lightweight and robust architectural board with excellent heat and sound insulation properties. .

The present invention provides a relatively thin board material made of GRC material with outstanding impact resistance and bending strength properties. This method aims to further reduce the weight of the GRC board material by burying fibers rich in fibers in parallel. I try to cover it with flavor. That is,
The filamentous part embedded in the GRC board material is a thin part, the space between the filaments is a thick reinforcement part, and the board material is flat on the outside.

Another feature of the GRC board material according to the present invention is that it particularly improves its heat insulation and sound insulation properties, increasing its utility as an exterior wall board material, etc., and improving the strength of the board by improving its heat insulation and sound insulation properties. Designed to minimize wear and tear.

In addition, this design uses a structure that absorbs expansion and contraction in the buried filament portions to prevent crutches from occurring on the surface of the board, which is exposed to harsh natural conditions as an exterior wall board. ing.

The GRC board according to the present invention has been designed based on the gist of its configuration in order to achieve the desired effect of these characteristics.
Lightweight, insulating wires such as foamed synthetic resin strings were buried in parallel at predetermined intervals in alkali-resistant glass fiber-reinforced concrete to create a relatively thin board, and considerable design changes were made in line with the gist of such a configuration. We aim to do this.

The details of the present invention will be described below with reference to a typical embodiment shown in the drawings. 1. Using a spray suction or other appropriate method, short fibers of alkali-resistant glass fibers are prepared according to the intended use.
It is a GRC board produced by kneading the required amount of the above together with aggregate, and within the flesh of the board 1, lightweight and highly insulating wires such as ropes and foamed synthetic resin strings 2 to 2 are arranged in parallel at required intervals. , is buried.

When embedding the filament 2, care was taken to position it as centrally as possible when the board 1 is relatively thin.

An example of a more typical manufacturing method of the board 1 will be explained with reference to FIG. After arranging the strips 2 to 2 at predetermined intervals, using a spray gun or the like, apply the GRC paste 5 to the frame surface of the formwork 3 by blowing with a gun or other method, and squeezing it with a roll or the like. After curing and demolding, Board 1 was created.

The architectural board according to the present invention has the above-mentioned characteristic structure, and utilizes GRC material that has outstanding impact resistance and bending strength properties, and is made of filament fibers in order to provide a board material that is as thin as possible and lightweight. It was constructed by interposing 2-2.

That is, in the board 1 according to the present invention, the filaments 2 to 2 are positioned at a certain distance from each other so that they are not placed in contact with each other, and the thickness of the filaments 2 to 2 is relatively small. The thinner portions located above and below the filament 2 are reinforced by the thicker portions of the filament 2.

In addition, in such a structure, external impact is absorbed in these two portions of the filament, and this external impact is prevented from reaching the entire surface of the board 1 as much as possible, and the noise transmitted to the board is reduced. is absorbed and erased by this filament 2 part.

Also, as a matter of course, the existence of such two filament parts, especially the hollow part created by the filament 2, has a good effect on heat insulation, and is good not only as a partition material but also as an exterior wall material. It is possible to use it.

Furthermore, by including such filaments 2 in the board, the board 1 itself becomes lightweight, making it easy to handle during construction, and at the same time has the effect of reducing the total weight as an exterior wall material. ing. Furthermore, by including the filaments 2 in the board, the amount of GRC, which is considered to be relatively expensive, can be reduced, and as a result, the board cost can be reduced.
