It is.

[0002]

2. Description of the Related Art Conventionally, reinforcing bars and steels have been used as reinforcing materials for concrete and the like, but these are heavy in weight, and corrosion and corrosion caused by carbonation of concrete due to infiltration of chlorides and carbon dioxide gas. There is deterioration due to electrolytic corrosion due to stray current. Therefore, various attempts have been made based on the recognition that the use of a fiber material for reinforcing concrete or the like can solve the above problems. For example, a fiber material
It has been proposed to be used as a chop, net, or three-dimensional woven fabric. However, structural materials reinforced with chop-shaped fibers are difficult to obtain a material having high proof stress and deformability because the length of the fibers is limited and the amount of fibers that can be mixed is limited. Further, the structural material using the net-shaped woven or knitted fabric is better than the chopped fiber, but cracks and interfacial peeling occurred between the nets. On the other hand, when a three-dimensional woven fabric is used, the above problem is improved, but a special technique for improving the filling property of the matrix is required. In addition, even if the texture is coarse, there is a difficulty in weaving. From such a viewpoint, conventionally, for example, Japanese Patent Application Laid-Open No. 63-159558

First, Japanese Patent Application Laid-Open No. 63-159558 discloses a method of knitting a double-Russell machine from the beginning by comparing the shape of a finished product. Next, JP-A-1-317152 discloses that a continuous fiber impregnated with a resin intersects in one direction and a direction orthogonal thereto to integrally form a cage-shaped reinforcing bar having an axial bar and a shear reinforcing bar. After forming a plastic anchoring block at both ends of the cage reinforcing bar, the cage reinforcing bar is placed in the concrete formwork, and concrete is applied to the shaft bar with tension applied to the shaft via the fixing block. The present invention proposes a prestressed concrete member itself that has been cast and cured, and a method and an apparatus for manufacturing the same. Japanese Unexamined Patent Publication No. 2-38038 discloses a three-dimensional structure in which a plurality of nonwoven fabrics having a network structure are arranged in parallel, and a nonwoven fabric or a thread having a network structure in which the nonwoven fabrics are bent into a corrugated shape, a mountain shape, a U-shape, or the like is laminated. It proposes a dynamic network structure.

SUMMARY OF THE INVENTION Japanese Patent Application Laid-Open No. 63-1595
No. 58 is a double Russell machine, which knits the finished product shape from the beginning, but it is difficult and inefficient to weave a three-dimensional woven or knitted fabric. Since there is no degree of freedom in design and it is not possible to prepare for mass production in advance, the production cost of fiber reinforcement becomes expensive, not only the delivery time becomes long, but also the size that can be produced is limited by the machine width etc. There is a limit, and it is also difficult to bring the machine to the construction site for manufacturing. Japanese Patent Application Laid-Open No. Hei 1-317152 discloses that the shape of the fiber reinforcing material is limited to only one type of cage reinforcing bar, and it is not possible to change to other various shapes and there is no design freedom. In addition, the production cost is high. Also, JP-A-2-38
No. 038 is slightly superior to any of the above proposals in terms of the degree of freedom of design. Because it is a three-dimensional network structure that is layered by combining with objects, even if there is a degree of freedom in design, the number of arranged network nonwoven fabrics arranged in parallel,
That is, since only the number of layers and the layer interval can be selected,
There are not so many variations in shape. further,
The method according to JP-A-63-206548 has a problem that the tensile strength of the bar is reduced and that the reinforcing fiber that extends linearly is bent due to the formation of the concave portion. Further, Japanese Patent Application Laid-Open No. 2-121523 discloses a method of forming an irregular shaped surface without disturbing the arrangement of reinforcing fibers.
However, when this method is used as a reinforcing material for concrete or the like, the contact area with concrete is only a linear or rod-shaped surface.
The number of the linear or rod-shaped members must be increased, and there is a problem that the cost is high.

[0004] The present invention has been proposed in view of the above-mentioned problems of the conventional fiber reinforcement, and an object thereof is to develop a shape structure capable of improving productivity and mass-producing,
Low cost, high degree of freedom of design, simplification and miniaturization of production equipment, factory production or on-site production, fiber reinforced body, its manufacturing method, and structural material using the reinforced material It is intended to provide.

In the present invention, first, a plurality of continuous fibers (multifilament, monofilament) are combined to form an adhesive. It is impregnated and cured to form the linear body (1). The fibers constituting the linear body (1) may be continuous fibers, and may be in any combination state. For example, multifilaments, tows, strands, rovings, etc., twisted, aligned, braided, etc. Either state may be sufficient. The fibers used include glass fibers, carbon fibers, aramid fibers, polyester fibers, vinylon fibers and the like. Examples of the adhesive to be impregnated into the fiber and cured include a synthetic resin adhesive, an inorganic adhesive such as water glass, and a rubber adhesive such as silicon. , Unsaturated polyester and the like.

As shown in FIG. 1, a method of forming the linear body (1) is as follows: a plurality of continuous fibers (2) are drawn out from a wound beam (3) while being aligned in parallel, and a reed (4) is obtained. After passing through, it is immersed in an adhesive tank (5), formed into a predetermined shape through a die (6), and further cured through a first heat curing device (7). Spools (8) and (9) are arranged before and after the adhesive tank (5), and a plurality of continuous fibers (2) are spread on a guide roller (10) in the adhesive tank (5) to spread the yarn bundle. To guide and supply. Thereby, the impregnation of the adhesive is made uniform, and the adhesive strength is improved. Rollers (12) and (13) are provided between the dies (6).
A plurality of devices for producing the linear body (1) are installed at desired arrangements and intervals.

The linear body (1) that has exited from the first heat-curing device (7) is pulled to a take-off device (15) while pulling a plurality of linear bodies in parallel at predetermined intervals by a linear body guide (14). Let me take. Then, the binding yarn winding device (16) is used by the binding yarn winding device (16) at a position immediately after exiting the first heat curing device (7).
7) is spirally wound.

As shown in FIG. 2, the binding yarn winding device (16) includes a beam (18) in which a plurality of continuous fibers are aligned and wound in parallel, and a plurality of beams extracted from the beam (18). An adhesive tank (19) for impregnating the continuous fiber with an adhesive;
Spools (20) and (21) installed before and after the adhesive tank (19) to uniformly impregnate the adhesive, and scraping of excess adhesive disposed at the outlet side of the adhesive tank (19) Means (not shown) and a die (not shown) for forming the binding yarn (17) into a predetermined shape are preferably provided, all of which are rotatably installed around the linear bodies (1) and (1). You. That is, the rotation applying means arranges a plurality of chain wheels (22) around the linear bodies (1) and (1), and stretches the chain (23) around the chain wheel (22) in an endless manner. This chain (2
A binding yarn winding device (16) is installed in a part of 3). Then, one of the chain wheels (22) is driven to rotate by a motor (24).

The chain (23) is stretched in an appropriate form such as a similar form according to the arrangement of the linear body (1). Then, the binding yarn winding device (16) spirally winds the binding yarn (17) impregnated with the adhesive around the linear body (1) arranged in a predetermined form, and then performs the second heat curing. The binding yarn (17) and the linear body (1) are fixed by the device (25). This fixation is performed by heating and curing the adhesive impregnated in the binding yarn (17) with the second heat curing device (25).

A binding yarn winding guide (26) is installed from the installation position of the binding yarn winding device (16) to an appropriate position in the middle of the second heat curing device (25), and the linear body (1) (1) To keep the distance between each other. This binding yarn winding guide (2
6) is supported in a cantilever support state on the outlet side of the first heat curing device (7).

The take-off device (15) has a clamp member (28) for gripping one end of the fiber reinforcement (27) created by the second heat-curing device (25), and is attached to the guide rail (29). It can be moved along and can be taken off while being pulled by an appropriate driving means (not shown).
This take-up speed can be set and changed to an appropriate value depending on the thickness, shape, curing speed and the like of the linear body (1).

The thickness of the linear body (1) is determined by the thickness and the number of continuous fibers (2) to be used. The shape of the linear body (1) can be realized in various shapes by changing the die (6), for example, a circle, an ellipse, a semicircle, a triangle, a trapezoid, a quadrangle, a polygon, and other irregular shapes. FIG.
(A) and (b) show an example thereof, (a) shows a case of an oblong shape, and (b) shows a case of a right triangle. The adhesiveness to concrete can be improved by changing the shape of the die (6).

The thickness and shape of the binding yarn (17) can be set in the same manner as the linear body (1).
For example, in order to increase the bonding area with the tape, a flat shape or a tape shape as shown in FIGS. The shape of the binding yarn (17) can be changed by changing the tension at the time of winding.

The arrangement of the linear bodies (1) is shown in FIG.
(E) of FIG. 3 and (f) of FIG.
(G) and (h) as well as various other arrangements. Also, it is needless to say that the number of the linear bodies (1) can be any number as needed. Regarding the method of winding the binding yarn (17) on the linear body (1), the winding may be performed by changing the winding pitch in addition to the case of winding at the same pitch. For example, as shown in FIG. 3 (i), a portion requiring strength to be combined with another structure such as both ends is provided with a binding yarn (17).
The winding pitch is made denser than other parts. Binding thread (1
The change of the winding pitch in 7) is performed by changing one or both of the take-up speed of the linear body (1) and the winding speed of the binding yarn winding device (16).

In the case where the structural material (30) is prepared using the above-mentioned fiber reinforcing material (27), the fiber reinforcing material (27) is adapted to conform to a desired shape of the structural material (30).
Are used alone or in combination. For example, as shown in FIG. 4A, a fiber reinforcing material (27) in which three linear bodies (1) are arranged in a right triangular shape at four corners of a quadrangle is arranged, and these are entirely bound together. It is wound and bound by the yarn (17a). For winding the binding yarn (17a), a binding yarn winding device (16) similar to that in FIG. 1 can be used, and another method may be used. FIG. 4 (b) is FIG. 4 (a)
Embedded in a concrete or mortar (31). FIG. 4C shows a slab-shaped structural material (30).
In this case, four fiber reinforcements (27) having a shape in which two linear bodies (1) are vertically arranged are arranged at predetermined intervals, and these are reinforced with another binding yarn (17a). It is made by winding and binding and burying it in concrete or mortar (31). FIG. 4D is a modified example of FIGS. 4A and 4B, in which the strength of the four corners when a shear force is applied to the structural material (30) is improved. 4 (b), (c) and (d) in FIG. 4 show the case where the fiber reinforcing material (27) is embedded in concrete or mortar (31). Good. It should be noted that the required action required for the fiber reinforcement (27) can be applied in advance to achieve the same effect as the prestressed concrete using a conventional reinforcing bar.

FIG. 4E shows a fiber reinforced material (27) used as a basic unit, and a plurality of the fiber reinforced materials (27) are connected in a predetermined shape to form a truss-like structure (32). The case where it is used as a material is illustrated.

In this case, as the shape of each girder constituting the truss, various shapes of fiber reinforcing members (27) such as those illustrated in FIG. 3 can be used. And connection of each girder material uses a simple joint jig, for example, a joint jig (33) as shown in FIG.
As shown in FIG. 4 (g), they may be joined with an adhesive or tied using a connecting string (34), and then may be bonded and cured with an adhesive. In this case, the joint jig (33)
Is composed of FRP or other material, and the connecting cord (34) is
It is composed of monofilaments, multifilaments or the like of continuous fibers similar to the linear body (1) or the binding yarn (17).

In order to improve the adhesion (anchor effect) between the linear body (1) and the concrete, as shown in FIG.
A pressing jig (35) or the like that performs an embossing operation while moving in synchronization with the movement of the linear body (1) is provided, and the linear body (1) is flat, tape-shaped, polygonal, Another linear shape or a linear body (1) as shown in FIG.
It is possible to provide a spool (36) revolving around the wire and to wind another continuous fiber (1a) drawn from the spool (36) around the linear body (1) to deform it.

Further, in order to improve the adhesion (anchor effect) between the fiber reinforcing material (27) and the concrete and to improve the strength of the fiber reinforcing material (27), the fiber reinforcing material (2) is used.
After making 7), another fiber (1b) is wound around the intersection of the linear body (1) and the binding yarn (17) as shown in (c) to (g) of FIG. A method of forming a knot or bonding with a resin or the like may be adopted.

Next, the following comparative experiment was conducted to confirm the bending performance of the reinforced concrete using the fiber reinforcing material (27) of the present invention having the shape shown in FIG.

[0027]

[Table 1]

The dimensions of each beam member are 15 cm in height and 1 in width.
0cm, length 180cm, effective height of reinforcement is 12cm
The reinforcing material ratio is a cross-sectional area ratio of the reinforcing material to concrete. In the bending loading test, as shown in FIG. 6B, a loading test was performed with a loading span of 160 cm and a bending span (equal bending moment section) of 30 cm.

FIG. 6C shows the load-displacement curve obtained as a result of the loading test. As is clear from the load-displacement curve, when any of the beam members cracks in the concrete (around 0.6 tf in FIG. 6C), the rigidity decreases and the slope of the curve changes. After that, the displacement increases linearly with the increase in the load, but in the case of reinforced concrete (A), the load has 2.0 tf and the rebar has yielded, so there is no subsequent increase in the load, and only the displacement increases. Bending failure has occurred. On the other hand, in the beam (B) reinforced by the carbon fiber and the beam (C) reinforced by the present invention, since the reinforcing material does not yield and behaves elastically, the load increases linearly until the final fracture occurs. However, in (B),
3.2 tons in shear type fracture mode with adhesive tensile fracture
It is broken at f, which is brittle. on the other hand,
The beam (C) reinforced with the product of the present invention is broken at about 4.0 tf in the form of bending crushing of concrete, and is slightly more brittle than the conventional reinforced concrete beam (A) but is about twice the load level. Also, the deformability shows the same excellent member performance. The beam member (C) reinforced by the product of the present invention resists shearing force depending on the number of the binding yarns (17) and the linear body (1) with respect to the linear body (1) and the amount of the binding yarn (17a). Since the beam member can be manufactured, there is no need to assemble the reinforcing member when manufacturing the beam member, and the manufacturing process can be shortened. As described above, when the product of the present invention is used as a reinforcing material for concrete, it is advantageous in terms of shortening the manufacturing process and mechanical performance of the beam member.

[0030]

According to the first aspect of the present invention, the contact area with concrete or the like can be increased without increasing the number of linear bodies. That is, since the spool is placed in front of the adhesive tank and the adhesive is impregnated by passing through the guide roller installed in the adhesive tank, the yarn bundle of the continuous fiber is spread on the guide roller, and the adhesive is And the control of the amount of adhesion becomes easy, the contact area between the binding yarn and the linear body is increased, the adhesive strength is improved, and the adhesive strength with concrete or the like is also improved. These effects are sufficiently exhibited even when the continuous fibers used in the linear body and the binding yarn are twisted yarns, but are more effective in the case of non-twisted yarns or untwisted yarns. Further, since the binding yarn is wound around the outer periphery of the linear body, it has an effect of preventing pull-out from concrete or the like, and the adhesive strength with concrete or the like increases. In addition, since the strands of the continuous fibers constituting the linear body and the binding yarn are bonded and integrated with the adhesive, they can resist stresses in various directions such as compression, tension, shear, bending, and peeling. Furthermore, it is lightweight and cheap,
The required shape and strength can be obtained, and there is no deterioration due to neutralization of concrete due to infiltration of chloride or carbon dioxide gas or electric corrosion due to stray current.

According to the second aspect of the present invention, a fiber reinforcing material can be produced continuously from fibers, and there is no need for a prepreg or a pre-impregnation step, so that the production method is simplified and the production efficiency is improved. Moreover, since it is not a prepreg, troublesome management becomes unnecessary. Furthermore, since the heating effect is applied immediately after the adhesive is applied, the adhesive is free from dripping and dirt. Further, a conventional weaving machine is not required, and the apparatus can be simplified. Therefore, the speed can be increased and the length can be increased, and the production efficiency is improved. In addition, since the size of the linear body can be changed only by changing the die, it can be manufactured freely from small to large.
By wrapping the binding yarn around the linear body by rotating the binding yarn winding device including the adhesive impregnating means, the whole device is simplified, and the adhesive can be impregnated and immediately wound. The adhesion of the resin to the binding yarn is improved, and the winding route of the binding yarn can be easily changed according to the shape of the linear body. Moreover, since the entire apparatus is simple, when used as a reinforcing material such as concrete, it can be easily manufactured on site.

According to the third aspect of the present invention, a structure in which a fiber reinforcing material having a high adhesive strength to concrete or the like can be embedded in concrete or the like to resist stress in each direction such as compression, tension, shear, bending and peeling. A lightweight structural material that can efficiently provide materials for use at low cost and has no risk of corrosion due to neutralization of concrete due to intrusion of chloride or carbon dioxide gas or deterioration due to electric corrosion due to stray current. Can be provided.

According to the fourth aspect of the present invention, concrete having sufficient strength capable of opposing stresses in various directions such as compression, tension, shearing, bending, etc., and being lightweight and capable of penetrating chloride or carbon dioxide gas. A structural material made of a truss-like structure that is not likely to be deteriorated by corrosion due to neutralization or electric corrosion due to stray current can be provided at low cost.
