Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fiber-reinforced frame structure in a fiber-reinforced cement product that incorporates a fiber frame obtained by stretching fiber wires in the frame.

Conventionally, in order to facilitate the uniaxial and 1000 line orientation technology of fibers, a fiber-reinforced cement product has already been proposed that incorporates a fiber frame obtained by stretching fiber wires in the frame. However, this proposal did not provide fiber reinforcement in the thickness direction of the product.

An object of the present invention is to provide a fiber frame structure which is improved to obtain a fiber reinforcement effect in the thickness direction, compared with the conventional structure, in order to obtain even greater strength in fiber reinforced cement products.

That is, in order to achieve this object, the fiber frame structure of the fiber reinforced cement product of the present invention is a fiber reinforced cement product incorporating a fiber frame obtained by stretching fiber wires on a frame of a desired shape. The fiber frame is configured to include a main fiber wire group surface and a reinforcing fiber wire group surface integrally arranged in a row orthogonal to the fiber wire group surface.

Therefore, in the present invention, since the fiber frame structure has a main fiber wire group surface and a reinforcing fiber wire group surface that is integrally connected orthogonal to the fiber wire group surface, the main fiber wire group In addition to the conventional planar reinforcing effect of the surface, the reinforcing fiber wire group surface also has a vertical reinforcing effect.

Here, the fiber wire in the present invention refers to the minimum length that is sufficient to stretch the required spacing, the minimum length that is sufficient to be wound once or multiple times, and any other length that can be stretched. refers to fibers that have a

For example, in the case of glass fiber, it refers to things like strands and rovings.

Stretching refers to the state in which the fiber wire is stretched around the frame by winding, sandwiching, hooking, tying, gluing, or other methods, or the state in which the fiber wire is stretched tightly around the frame, or the fiber wire is stretched slightly around the frame. It means to hold it in a tensioned state. In any case, it refers to a state in which the fiber wire is passed between at least two frames.

Hereinafter, the present invention will be described in detail by way of examples.

In the description of each embodiment, the same reference numerals are used for the same components in the drawings for convenience.
