Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a corrugated fiber reinforced plate formed by a fiber strand and a multilayer fiber sheet,

The present invention relates to a corrugated fiber reinforced plate, and more particularly, to a corrugated fiber reinforced plate for attaching and structurally reinforcing a corrugated fiber to a surface of a structure, which comprises a fiber formed by processing a reinforcing fiber filament made of a plurality of single fibers A multi-layered fiber sheet is formed by laminating a three-directional fiber sheet and an external molded sheet by arranging a fiber strand in the longitudinal direction of the fiber reinforced plate, ) And a method of constructing the corrugated fiber reinforced plate.

Generally, structures such as steel beam, concrete column or beam, or wall are mainly reinforced by iron plate or concrete pouring. In other words, these structures are reinforced with steel plate or concrete added additionally. However, this reinforcing method has a disadvantage that the weight of the structure is increased and the workability is not good.

Recently, a fiber sheet reinforcing method using a fiber having lightweight, high strength, high elasticity, excellent durability and corrosion resistance has been developed and applied.

Such a fiber sheet reinforcing method is a method of reinforcing the rigidity of a structure by attaching a fiber sheet incorporating high-strength fibers to the structure. At this time, the fiber sheet is generally divided into a carbon fiber sheet, a glass fiber sheet, and an aramid fiber sheet into which carbon fiber, glass fiber, or aramid fiber are respectively mixed, and the most inexpensive glass fiber sheet is most widely used. That is, since the carbon fiber sheet or the aramid fiber sheet is expensive, its performance such as rigidity, corrosion resistance and durability is excellent, but its use is limited.

The above-mentioned fiber sheet is formed in a planar shape by arranging high-strength fibers made of carbon fiber, glass fiber, or aramid fiber in a line. That is, the fiber sheet is composed of only one fiber to form a planar surface.

Such a fiber sheet is attached to the structure by a resin-based adhesive such as epoxy. At this time, the fiber sheet is attached to the structure after the adhesive is applied to the structure. Such a fibrous sheet can be attached to the structure and then protected again with a resin-based adhesive. That is, the fibrous sheet may be attached to the structure and then a resin-based adhesive may be applied to the surface.

Concrete structures, on the other hand, are required to be reinforced due to the period of use, changes in usage, and reinforcement of structural standards. Current reinforcing technology is led by the technique of applying epoxy to the surface of the stiffener and attaching it to the concrete surface to reinforce it.

 The reinforcing material used for the concrete structure may include steel fiber, glass fiber, nylon fiber, polypropylene fiber, asbestos fiber, carbon fiber ) Are used.

FIG. 1A is a perspective view showing a planar fiber-reinforced plate according to the prior art, and FIG. 1B is a cross-sectional view showing that the fibers are cracked in the direction of the fiber in the planar fiber-reinforced plate shown in FIG.

As shown in Fig. 1A, the planar fiber-reinforced plate according to the prior art is a flat-type fiber-reinforced plate 10 in the form of a straight line, and its surface is formed flat.

In the construction of such a flat fiber reinforced plate 10, an epoxy is applied and reinforced in the field. First, the surface of the concrete to be repaired is processed, the epoxy is applied to the surface portion of the concrete structure, .

At this time, when the coating thickness of epoxy is generally 2 to 5 mm, the adhesion effect is excellent. However, due to the planar structure of the planar fiber-reinforced plate 10, the thickness of the appropriate epoxy is often not secured.

Further, in the conventional planar fiber-reinforced plate 10, the body is formed by impregnating epoxy with a thickness of, for example, 2 to 5 layers of polypropylene fiber material 11 having a predetermined length, As shown in FIG. 1B, when a predetermined period of time elapses, the plate-shaped fiber reinforced plate 10 according to the prior art has a phenomenon in which the body is longitudinally split from the ends thereof. In other words, since the polypropylene fiber material 11 forming the body is directional, a crack 12 is generated in the direction P1. As a result, the strength of the planar fibrous reinforcing plate 10 This weakens the stiffness and causes structural weakness of the concrete structure.

Accordingly, a technique for preventing the fiber material 11 from being deteriorated in structure (12) without causing crack 12 in the grain direction (P1) even after a long period of time has elapsed in the conventional planar fiber- .

The conventional planar fiber-reinforced plate 10 according to the related art has a single physical property by impregnating a single material fiber with an epoxy resin. For example, the flat-plate type fiber reinforced plate 10 made of carbon fiber has excellent structural strength due to its physical properties, but has a conductor characteristic, so that there is a problem that an electric shock accident or a short circuit accident easily occurs. On the other hand, the planar type fiber reinforced plate 10 made of glass fiber has excellent insulation and flame retardant effect, but has a problem of poor structural strength.

 Therefore, it has been necessary to develop a fiber reinforced plate that can effectively prevent electric shock or short-circuiting accident due to the combination of individual material characteristics and excellent structural strength and insulation and flame retarding effect at the same time.

As a prior art for solving the problems of the above-mentioned planar fiber-reinforced plate, Korean Registered Patent No. 10-992168, filed by the applicant of the present invention and registered as a patent, discloses "a corrugated fiber- Method "has been disclosed, which will be described with reference to Fig.

2 is a view showing a corrugated fiber reinforced plate for concrete according to the prior art.

Referring to FIG. 2, the conventional corrugated fiber reinforced plate 20 according to the related art is a fiber reinforced plate attached to the surface of a concrete structure to structurally reinforce a concrete structure, The two-way glass fibers in which the glass fibers 22 in the transverse direction are arranged orthogonally to each other so as to be orthogonal to the fibers 21 are arranged and the carbon fibers having excellent mechanical characteristics are arranged in the lower layer 24, The constituent fibers are impregnated in the epoxy 25 to form a plurality of mountains 23r and valleys 23g in the longitudinal direction and a corrugated portion 23 in the width direction.

The corrugated fiber reinforced plate 20 according to the prior art has a structure in which the structural rigidity of the reinforced plate itself is increased by removing a simple straight shape and the thickness of the epoxy applied to the surface of the concrete structure can be sufficiently maintained to 2 to 5 mm And it is possible to secure a sufficient adhesion area, so that the effect of adhesion to the concrete structure is excellent, thereby maximizing the structural reinforcement effect.

According to the conventional corrugated fiber reinforced plate for concrete 20, cracking of the built-in fiber layer can be effectively prevented even after a long period of time, so that the structural strength can be prevented from being lowered, , And at the same time, it can be used safely with insulation and flame retardant properties.

However, in the case of the corrugated fiber-reinforced plate 20 according to the related art, since the glass fibers are arranged to be orthogonal to each other in two directions, not only the manufacturing cost is increased but also the manufacturing time is long.

On the other hand, as another prior art, Korean Patent No. 10-773224 discloses an invention entitled " fiber-reinforced sheet and its manufacturing method and apparatus ", specifically, the reinforcing fiber is pulled in one direction The first reinforcing fiber sheet is arranged in the longitudinal direction of the fiber-reinforced sheet, and the first reinforcing fiber sheet is folded and wound spirally so as to overlap the first reinforcing fiber sheet with the inclination of the winding angle? , A first reinforcing fiber sheet having a length of 0 mm in the direction of the reinforcing fiber sheet with respect to the longitudinal direction, a second reinforcing fiber sheet having a length of + θ ㅀ, and a third reinforcing fiber sheet constituting -θ ㅀ And a fiber-reinforced sheet which can easily laminate the reinforcing fiber sheet in three layers and in which delamination between layers is hard to occur.

However, in the case of the fiber-reinforced sheet according to the related art, since the reinforcing fiber sheet formed of the reinforcing fiber is formed into three layers, a large amount of reinforcing fiber is required, which increases the cost.

Korean Patent No. 10-992168 filed on July 20, 2010, entitled "Corrugated Fiber Reinforced Plates for Concrete & Korean Patent No. 10-773224 filed on Feb. 17, 2006, entitled "Fiber-reinforced Sheet, Korean Registered Patent No. 10-980659 filed on Dec. 28, 2007, entitled "Blended Rigid Sheets for Intensity Reinforcement" Korean Patent Publication No. 2000-1355 (Publication Date: January 15, 2000), entitled "Epoxy-carbon fiber reinforced plate formed by synthesizing epoxy and carbon fiber sheet and method for manufacturing the same"
