Description

Reinforced concrete structure and reinforcement method reinforced using wire {REINFORCED CONCRETE STRUCTURE USING A WIRE AND REINFORCEMENT METHOD FOR THE SAME}

The present invention relates to a reinforced reinforced concrete structure, and more particularly, to a reinforced concrete structure and a reinforcement method reinforced using a wire.

Structures are damaged or deteriorated due to various factors. The risk of damage to structures has increased due to the recent earthquakes in Gyeongju and Pohang. In particular, for piloti structures that do not have walls on the first floor, the first floor is the weaker floor, so there is a greater risk of damage to the structure due to an earthquake. Therefore, repair and reinforcement are required in order to increase the strength of the damaged or aging structure to extend the physical life and to exhibit its original function.

In particular, in reinforced concrete columns, the transverse reinforcing bar that properly confines the concrete is often not sufficiently used, so when an earthquake occurs, the lateral deformation of the column easily occurs, resulting in brittle fracture.

There are various methods of reinforcing reinforced concrete structures to compensate for this, but generally, a method of attaching a highly ductile member such as a steel plate to the structure by using an epoxy bonding method is widely used. This is because by attaching a member with high ductility, it can play a role in delaying the damage of concrete under compressive load and inducing the ductile behavior of reinforced concrete structures. This is a great advantage that the construction period is short and can be applied to structures in use, but there is a problem in that the reinforcement may peel off and fall off because the parent body and the reinforcing material are not integrally attached.

As described above, in the prior art, in addition to steel plates, reinforcing materials such as carbon fibers or fiber plates are bonded to the reinforced concrete structure for reinforcement, and a method using an epoxy resin as an adhesive is mainly used. This is because it is known in the field of repair and reinforcement technology that a sufficient reinforcing effect can be obtained simply by bonding a reinforcing material to the structure surface with an epoxy adhesive.

However, the epoxy used as an adhesive has a problem in that the coefficient of linear expansion (the degree to which the material expands and contracts according to the temperature change) is different from that of concrete, so that the phenomenon of spontaneous peeling occurs according to the temperature environment change. Therefore, the biggest problem is that if the adhesive peeling phenomenon of the epoxy occurs before the reinforcing effect of the reinforcing material is exerted, the reinforcing effect by the reinforcing material cannot be expected at all.

In addition, the reinforcing method of bonding a reinforcement material to the surface of a reinforced concrete structure using an adhesive such as an epoxy resin requires a step of surface-treating the adhesive surface of the concrete structure to which the reinforcement material is adhered. This is to increase the adhesion of epoxy, and it is carried out in more complex steps than general surface treatment steps.Since this surface treatment is performed using a grinder and sandpaper, a lot of dust is generated, so there is a problem that it is difficult to treat dust depending on the working environment. .

In addition, in the reinforcement method of bonding the reinforcement material to the surface of a reinforced concrete structure using an adhesive such as epoxy resin, the process of injecting an epoxy-based adhesive at a predetermined thickness, curing, and pressing is performed for the integration of the concrete and the reinforcement material. However, it takes a considerable amount of time to cure the epoxy, and shrinkage occurs in the epoxy. Therefore, it is difficult to directly observe the bonding interface structure between the surface of the structure and the reinforcing material, so that it is difficult to identify cracks in the concrete, and it is not possible to accurately determine whether the reinforcing material is peeled off, which may lead to unexpected accidents.

In particular, it is widely known that epoxy-based adhesives contain flammable materials and have an environmental problem of generating toxic gases while burning when a fire occurs. In recent years, social demand for eco-friendly construction methods has continuously increased at construction sites, and accordingly, the need for a reinforced concrete structure reinforcement method to replace epoxy adhesive has emerged.

The present invention is an invention conceived to solve the problems of the prior art described above, when reinforcing reinforced concrete beams or columns, without using a large amount of adhesive such as epoxy on the entire bonding surface to attach the reinforcing material to the concrete structure. A method of minimizing the use, and by fastening the structure and the reinforcing material using bolts, nuts, wires, or coupling members to effectively exert the reinforcing effect by the reinforcing material without being affected by the performance and construction condition of the adhesive epoxy. It is to provide the used structure.

It is proposed to apply a crimping method using a wire. However, it will be well understood by those skilled in the art that the crimping method using the bolting and the crimping method using a wire may be widely applied as necessary, and may be applied together. Hereinafter, an embodiment of a reinforcing method of a reinforced concrete structure using a first wire and a second wire of the present invention will be described with reference to FIGS. 1 to 3.

1 is a diagram illustrating a method in which a reinforced concrete structure reinforcement method using a first wire and a second wire is applied to a structure according to a first embodiment of the present invention. Figure 2 is a reinforced concrete structure using a first wire and a second wire according to the first embodiment of the present invention, the first wire is bound and the first wire and the second wire is connected to the surface (in FIG. It is an exemplary view showing the opposite side of the side with the binding member 15), and FIG. 3 is a diagram illustrating a reinforced concrete structure using a first wire and a second wire according to the first embodiment of the present invention. It is a diagram exemplarily showing a wire being bound by a wire binding member and a state in which a first wire and a second wire are connected by a wire connecting member.

As shown in FIG. 1, the concrete structure 10 according to the reinforcement method of the reinforced concrete structure using the first wire and the second wire of the present invention is a first wire for confining the reinforced concrete member 100 ( 11), a second wire 12, a first wire protecting member 13, a second wire protecting member 14, a wire binding member 15, and a wire connecting member 16 may be included.

In Figures 1 to 3, the reinforced concrete member 100 was described as an example as a square reinforced concrete column. However, the reinforced concrete member 100 is not limited to a column, and may include all reinforced concrete members of various shapes such as a reinforced concrete beam or slab having various cross-sectional shapes such as a circle.

The first wire 11 and the second wire 12 can be reinforced stronger than when reinforced with one wire by restoring the deformation or stress of the existing structure as two wires are installed. It can induce the improvement of the load-bearing performance by delaying the damage of and leading to the ductile behavior. In addition, depending on the shape of the concrete member 100, it is possible to improve the tensile performance by installing the first wire 11 and the second wire 12.

The first wire 11 and the second wire 12 of the present invention are members manufactured by assembling a general wire rope, that is, a wire to form a strand and winding it around a core at a constant pitch. I can. In addition, it may be a wire made of a shape memory alloy.

As the first wire 11 and the second wire 12 are wrapped around the circumference of the reinforced concrete member 100 and fastened at both ends, the first wire 11 and the second wire 12 are tensioned. Post tension is introduced into the reinforced concrete member 100.

In one embodiment of the present invention, the first wire 11 and the second wire 12 may be installed to surround the circumference of the rectangular reinforced concrete member 100 as shown in FIG. 1.

More specifically, in an example of the present invention, in order to prevent the first wire 11 and the second wire 12 from being broken at the edge of the reinforced concrete member 100, the first wire protection member 13 and the first wire It can be installed including a two-wire protection member 14. The first wire protection member 13 and the second wire protection member 14 are formed in an L shape, and are perforated so that the first wire 11 and the second wire 12 can pass therethrough. to be. The first wire protection member 13 and the second wire protection member 14 are installed to prevent direct contact between the corners of the reinforced concrete member 100 and the first wire 11 and the second wire 12. Thus, it is possible to avoid damage or breakage of the first wire 11 and the second wire 12 due to abrasion by the edge.

Therefore, the first wire 11 is passed through the inside of the first wire protection member 13, the second wire 12 is passed through the inside of the second wire protection member 14, and the first wire 11 And the second wire 12 is wrapped around the reinforced concrete member 100 in the circumferential direction of the cross section, while the first wire protection member 13 and the second wire protection member 14 are installed at each corner. Thereafter, both ends of the first wire 11 are fastened to and fixed to the wire binding member 15 so that the first wire 11 is installed so as not to slide in a position surrounded by the reinforced concrete member 100, and the binding member The wire connection member (16) is installed at both ends of the first wire that is fastened through (15), and the second wire (12) does not slide in a position surrounded by the reinforced concrete member (100). 16) and installed.

At this time, the first wire protection member 13 and the second wire protection member 14 are located at the corners of the reinforced concrete member 100 to protect the wire from abrasion of the first and second wires. And, the wire binding member 15 is a member for binding the first wire, and the wire connection member 16 is the first wire 11 when the first wire 11 passes through the wire binding member 15 and is bound. It is a member connecting both ends of the first wire 11 and both ends of the second wire 12.

In the case of a reinforced concrete structure reinforced using a wire and a reinforcing plate according to an embodiment of the present invention, the first wire protection member whenever the pair of the first and second wires is placed on the reinforced concrete member 100 Four (13) may be installed, the second wire protection member 14 may be four, the wire binding member 15 may be one, and the wire connection member 16 may be two.

At this time, the first wire protection member 13 and the second wire protection member 14 are at the corners of the reinforced concrete member 100 shown in the vertical direction in FIG. 1, the wire binding member 15 and the The wire connecting member 16 may be located on one of four side surfaces of the reinforced concrete member 100 on which the first wire 11 and the second wire 12 are surrounded in a transverse direction.

In one embodiment of the present invention, the first wire 11 surrounds the reinforced concrete member 100 in a cross-sectional direction, and four first wire protection members respectively located at four corners of the reinforced concrete member 100 It can penetrate both ends of (13). The first wire 11 penetrating the first wire protection member 13 installed at the corner of the reinforced concrete member 100 penetrates the first wire protection member 13 and does not fall down, but a reinforced concrete member Although it is located around 100, since both ends of the first wire 11 are not fastened, there may be a state in which tension is not applied.

Accordingly, a wire binding member 15 may be installed to impart tension to the first wire 11 by fastening both ends of the first wire 11 penetrating the first wire protection member 13. . The wire binding member 15 may be fastened to maintain a continuous tension to the first wire 11 reinforced to the reinforced concrete member 100, and the first wire protecting member 13 is a first wire. (11) It is possible to supplement the effect of the wire binding member 15 so that the tension can be maintained.

In this case, the wire binding member 15 for binding both ends of the first wire may have two upper and lower through holes in the wire binding member 15. One of the four sides of the rectangular reinforced concrete member 100 is surrounded by the reinforced concrete member 100 in the cross-sectional direction and has passed through the first wire protection member 13 When meeting at, one end of the both ends of the first wire 11 passes through the through hole located at the top of the through holes formed above and below the wire binding member 15, and the other end of the both ends of the first wire 11 is The wire binding member 15 may pass through a through hole located under the lower portion of the wire binding member 15.

At this time, both ends of the first wire 11 are formed using one or more of a generally known terminal processing method of a wire rope, that is, a socket, a thimble, a wedge, an ice ply, and a clip, and when forming, the wire is bound The first wire (11) is formed to have a larger size of the finishing material (sleeve) for fixing both ends of the first wire (11) than the size of the through hole of the member (15). ) Can be bound.

At this time, in the terminal processing method of the wire rope, the socket is hardened by inserting the end of the wire rope into the hardware and melting and injecting lead, and the thimble overlaps the end of the wire rope in a droplet shape to form a ring with a part of the wire rope. The wedge is a member that is inserted so that the inside of the ring is not worn, and the wedge is a type of wedge, which forms the end of the wire rope by wrapping the rope around the wedge and pushing it into the case to bind it. It means that the wire rope ends are connected to each other by bending them into a shape like a thick ring. In addition, wire rope terminal processing using a clip can be performed using a U-shaped bolt when fixing the wire rope. It will be easily understood by those of ordinary skill in the art that a generally known terminal processing method of a wire rope can be used in addition to the above-listed terminal processing method of the wire rope.

In one embodiment of the present invention, after passing through the wire binding member 15, the second wire 12 may be further coupled to both ends of the first wire formed in a ring shape. At this time, both ends of the second wire 12 are formed in a ring shape, and may be formed by the terminal processing method of the wire rope described above. In addition, by combining the first wire 11 and the second wire 12, the first wire and the second wire can be formed to overlap in an X-shape on two of the side surfaces of the rectangular reinforced concrete member 100. have.

At this time, the first X-shape may be formed as in the side (right side in FIG. 1) where the wire binding member 15 is visible among the two side surfaces of the reinforced concrete member 100 shown in FIG. A second X-shape may be formed as in the right side of the two side surfaces of the reinforced concrete member 100 shown in 2 (the opposite side of the side where the wire binding member 15 is visible).

In addition, wire connecting members 16 are installed at both processed ends of the first wire 11 to connect both ends of the second wire 12. At this time, the wire connection member 16 may use one or more of a quick link, a turnbuckle, and an eye bolt, which are generally known as a fastening method of both ends of the wire.

At this time, the quick link means that there is a gap in the middle of the member formed in a form in which the O-shaped is laid down, so the wire can be caught on both sides, and based on the gap, a male thread is formed at one end and a nut is formed with a female thread at the other end. Then, turn the nut and connect it with the male thread of one end to connect both ends of the wire. The turnbuckle has threaded rods on the left and right, and the threaded part is connected with a common nut. Eye bolts are bolts with a hook on the head. It will be easily understood by those of ordinary skill in the art that a generally known method of fastening both ends of a wire rope may be used in addition to the above-listed fastening method of both ends of the wire rope.

2, the first wire 11 and the second wire 12 are connected using the wire binding member 15 and the wire connecting member 16 in the same manner as in the above-described embodiment. , A portion of the first wire 11 and the second wire 12 may be overlapped in an X-shape. Accordingly, the first wire 11 and the second wire 12 recover stress in various directions of the reinforced concrete member 100 to prevent deformation in various directions and reinforce with one wire or reinforce two wires in parallel. It is possible to reinforce the reinforced concrete member 100 more effectively than when doing so.

That is, in the case of reinforcing with one wire or reinforcing two wires in parallel, the wire surrounds the reinforced concrete member 100 only in the cross-sectional direction, so that only reinforcement occurs in the cross-sectional direction. Likewise, when two wires are overlapped in an X-shape on two sides of the reinforced concrete member 100, the two sides can be reinforced with a force in the diagonal direction, and the other two sides are reinforced with a force in the cross-sectional direction. This makes it possible to reinforce with force in various directions.

In this case, when the wire is reinforced to be formed in an X-shape, one wire is from bottom to top and the other is from top to bottom on one side between two consecutive edges (meaning the vertical line shown in Fig. 1). In addition to the diagonal direction in which the wire is reinforced by being enclosed, reinforcement is possible in the x-axis and y-axis directions in which the diagonal force is decomposed.

In addition, a point where two wires meet in an X-shape is located on one of the side surfaces of the reinforced concrete member 100, so that the reinforced concrete member 100 can be constrained by two wires at one point.

The conventional reinforced concrete member reinforcement method has a problem that the reinforced concrete member 100 is reinforced in the cross-sectional direction and thus reinforces only a certain area of the reinforced concrete member 100, and thus the reinforcement area is insufficient. Reinforcement in various directions is possible by the first wire 11 and the second wire 12, and at this time, a pair of the first wire protection members 13 and the second wire installed at each corner of the reinforced concrete member 100 When the two-wire protection members are installed with a wide distance from each other, the first wire 11 and the second wire 12 are located farther from the edge, so that the shape of the X-shaped overlap may be further increased. That is, there is an advantage in that the area to be reinforced can be determined according to the distance between the first wire protection member 13 and the second wire protection member 14.

In addition, in the case of a reinforced concrete structure reinforced using a wire and a reinforcing plate according to an embodiment of the present invention, both ends of the first wire 11 are provided in two through holes existing up and down in the wire binding member 15. The first wire (11) is made to pass through each of the first wires and finishes both ends of the first wire (11), and then by injecting epoxy into the through hole of the wire binding member (15) to increase the area to which the wires are bound. A reinforced concrete member that can stably bind both ends of) and surround the first and second wires by further connecting the second wire 12 to both ends of the first wire 11 that is stably bound. In (100), an X-shaped wire may be overlapped.

In this case, when epoxy is injected into the through hole of the wire binding member 15 through which both ends of the first wire pass, a stronger tension is applied to the first wire, thereby effectively reinforcing it.

Hereinafter, an embodiment of a reinforcement method using a reinforcement plate among the reinforced concrete structure reinforcement methods using a reinforcement plate of the present invention will be described with reference to FIGS. 4 to 6. Hereinafter, in order to clearly describe the configuration of the bolting fastening method, the description and detailed description of the reinforcing configuration using the wire as described above are omitted. However, it will be understood by those of ordinary skill in the art that the configuration of the bolting fastening method described below can be applied to the configuration using the wire described above.

4 is a diagram illustrating a method in which a bolt, a nut, and a coupling member are applied to a structure in a method of reinforcing a reinforced concrete structure using a reinforcing plate according to a second embodiment of the present invention. FIG. 5 is a view exemplarily showing an anchor receiving portion and an anchor formed on an outer surface of a reinforced concrete member in the reinforcement method and reinforcement structure of a reinforced concrete structure using a reinforcing plate according to a second embodiment of the present invention, FIG. 6 is a reinforcement construction method and reinforcement structure of a reinforced concrete structure using a reinforcing plate according to a second embodiment of the present invention, a reinforced concrete member in which an anchor is embedded in an anchor receiving portion and an anchor accommodation formed on the outer surface of the reinforced concrete member It is a view exemplarily showing a reinforcing plate in which a through hole is formed at a position corresponding to a position of the negative, a coupling member connecting between the reinforcing plates and a hinge connection part are formed.

As shown in Figure 4, the concrete structure 20 by the reinforcement method of the reinforced concrete structure using the reinforcing plate of the present invention is a reinforced concrete member 100, a reinforcing plate 200 and an anchor 110 for fastening them, bolts 120, a coupling member 203 connecting between the first nut 130 and the reinforcing plate 200 and a hinge connection part 204 may be included.

In Figures 4 to 6, the reinforced concrete member 100 has been described as an example as a square reinforced concrete column. However, the reinforced concrete member 100 is not limited to a column, and may include all reinforced concrete members of various shapes such as a reinforced concrete beam or slab having various cross-sectional shapes such as a circle.

In this way, an anchor receiving portion 101 for installing by burying the anchor 110 may be formed on the outer surface of the reinforced concrete member 100 such as a column, beam, or slab that requires repair and reinforcement according to the present invention. . The anchor receiving part 101 is formed by digging a groove on the surface of the reinforced concrete member 100. In addition, the anchor 110 is embedded in the anchor receiving portion 101 formed on the outer surface of the reinforced concrete member 100.

In general, an anchor is a device that is installed to fix a skin attachment to a concrete structure.After drilling a hole in the concrete and installing an anchor, it can be fixed by attaching the skin attachment to the exposed area outside the concrete and fastening it with a nut. Do.

The anchor of the present invention is a conventionally known various types of anchors, for example, chemical anchors, set anchors, all anchors, wedge anchors, frame anchors ( It may include a frame anchor, a sleeve anchor, a strong anchor, a dropin anchor, and the like.

In an embodiment of the present invention, the anchor receiving portion 101 may be formed in or on the outer surface of the rectangular reinforced concrete member 100 as shown in FIG. 4.

More specifically, in an example of the present invention, two left and right anchor receiving portions 101 may be formed on one surface of the reinforced concrete member 100. In addition, the number of the anchor receiving portions 101 formed on one surface may be variously selected according to the concrete crack state and the degree of reinforcement. That is, when the surface area of the structure to be reinforced is large, the number of anchor receiving portions 101 may be sufficiently increased so that the reinforcing plate 200 attached to the reinforced concrete member 100 may be stably attached. For example, as shown in FIGS. 5 and 6, it can be installed while increasing the number of anchor receiving portions 101 in the vertical direction of the pillar on one surface of the reinforced concrete member 100 of a square pillar.

In addition, the anchor receiving portion 101 may be formed on all slopes of the reinforced concrete member 100, respectively, as shown in FIG. 4. However, depending on the crack condition and shape of the concrete to be reinforced, and the degree of reinforcement, it can be formed on only one side, on two sides facing each other, on two sides adjacent to the corner, and on three sides. May be.

The reinforcing effect of the conventional steel plate reinforcement method using epoxy is excellent in that a steel plate is used as a reinforcing material, but there is a problem that the reinforcing effect is remarkably inferior when the epoxy injection step is complicated and the epoxy is not sufficiently injected. In addition, in the case of increasing the thickness of the cross section of the reinforcing material to improve the reinforcing effect, it is necessary to increase the amount of epoxy used and the thickness of the adhesive layer, not the reinforcing material, because the epoxy injection thickness must be increased together to withstand the increased weight of the reinforcing material Was.

In addition, in the conventional reinforcing method using epoxy as an adhesive, since epoxy must be injected between the structure and the reinforcing material, it is essential to prevent the epoxy from leaking. For example, a reinforcing plate must be placed on the entire slope of the column and the circumference of the reinforcing plate is sealed with a separate sealing operation, or a separate injection hole for epoxy injection must be installed while the epoxy does not leak out by welding between the steel plates. It was complex and required skilled skills.

However, in the present invention, since epoxy is not injected between the reinforced concrete structure and the reinforcing plate, which is a reinforcing material, since it does not go through the frame sealing operation and welding process as in the prior art, the difficulty of the operation is low and the unskilled person can also easily construct it. In addition, since an adhesive is not used, even when an increase in the thickness of the reinforcing material is desired, the increase in the amount of the adhesive used accordingly does not need to be considered. Therefore, a reinforcing material having a required thickness can be easily selected and constructed.

At this time, the depth of the anchor receiving portion 101 is determined according to the effective depth at which the anchor 110 and the bolt 120 used for fixing the reinforcing plate 200 can effectively act, and the anchor receiving portion 101 The diameter of) is also determined according to the effective diameter at which the anchor 110 and the bolt 120 can act effectively. The anchor 110 is installed in the anchor receiving part 101 and has a female thread corresponding to the thread of the bolt so that the bolt can be inserted into the anchor 110. The size, length, and thickness of the anchor 110 and the bolt 120 are determined according to the crack state of the concrete, the degree of reinforcement, and the size and weight of the reinforcing plate 200 to be attached.

In addition, the depth of the anchor receiving portion 101 may be constructed to be deeper than the length of the anchor 110 in order to cope with an external impact.

Before and after the anchor 110 is embedded in the anchor receiving part 101 to increase the fixing force and adhesion of the anchor 110 to the reinforced concrete member 100, between the anchor receiving part 101 and the anchor 110 An adhesive (for example, an epoxy adhesive) and a grouting material may be additionally injected into the.

For example, after forming the anchor receiving portion 101, an adhesive may be injected into the anchor receiving portion 101, and then the anchor 110 may be installed, and the bolt 120 is fastened to the anchor receiving portion 101. Prior to the following, the bolt 120 may be fastened after the adhesive is injected into the female threaded portion of the anchor 110. That is, an adhesive may be filled between the anchor receiving portion 101 and the anchor 110 formed in the reinforced concrete member 100 and between the anchor 110 and the bolt 120.

A through hole 210 is formed in the reinforcing plate 200 at a position corresponding to the position of the anchor receiving part 101. The reinforcing plate 200 is fixed to the reinforced concrete member 100 by penetrating the bolt 120 through the through hole 210 and tightening the first nut 130.

In the present invention, since an epoxy adhesive is not used between the concrete structure and the reinforcing material, it is not necessary to separate the reinforcing material from the concrete structure in order to inject the epoxy, so that the reinforcing material and the concrete structure can be directly and closely fixed. In addition, the problem of the prior art in which brittle fracture of the concrete structure occurs before the epoxy adhesive interface layer is peeled off and the reinforcing material exhibits reinforcing performance can be solved through the bolting compression method of the present invention.

However, in the case of using the bolting compression method as described above, the bolt must be able to be firmly fixed to the structure without loosening. In particular, the anchor 110 embedded in the concrete structure 20 does not deviate from the anchor receiving portion 101 even when vibrations including earthquakes occur, and when the concrete expands and contracts, and the reinforcing plate 200 and the reinforced concrete member The bolt 120 and the first nut 130, which are the main roles for fixing the 100, should not be loosened. Accordingly, in the present invention, a spring, which is an elastic structure, is included in the reinforcing structure for this function.

In addition, the reinforcement plate 200 may be a reinforcement plate 200 that surrounds the entire circumference of the reinforced concrete cross section, or may be a reinforcement plate 200 that surrounds the circumference of the reinforced concrete cross section. That is, the entire circumference of the reinforced concrete cross-section may be reinforced with one reinforcing plate 200, or the circumference of the reinforced concrete cross-section may be reinforced several times with multiple reinforcement plates 200.

At this time, the first reinforcement plate 200 is bent to correspond to the shape of the cross section corresponding to the side surface of the reinforced concrete member 100 between two consecutive sides of the reinforced concrete member 100 shown in FIG. The second reinforcing plate 200 can be formed in a "a" shape, and the second reinforcing plate 200 is also bent to correspond to the shape of the cross section corresponding to the side surface of the reinforced concrete member 100 between the remaining two consecutive sides of the reinforced concrete member 100 It can be formed into a “b” shape. At this time, the two consecutive sides of the reinforced concrete member 100 may mean two consecutive sides of the four sides of the rectangle shown in FIG. 4, and the four corners and the ceiling where the reinforced concrete member 100 meets the floor. It can mean the four corners that meet. In addition, the cross-section corresponding to the side surface of the reinforced concrete member 100 may refer to the remaining four surfaces except for a surface that meets the ceiling and the floor when taking a rectangular parallelepiped reinforced concrete as an example.

The first reinforcing plate 200 may be formed by bending one plate, but it may be formed in a “b” shape by connecting two plates, and the second reinforcing plate 200 may also be formed by bending one plate. It can be, but it can also be formed in a “b” shape by connecting two plates. These first reinforcing plate 200 and second reinforcing plate 200 may be transported to a construction site in a state in which two reinforcing plates 200 are connected, respectively, or may be connected at the construction site.

To this end, between the first reinforcing plate 200 and the second reinforcing plate 200 may be connected to each other by a hinge connecting portion 204 at the bent portion. The photo below is an example of connecting between the reinforcing plates 200 by a hinge connection part 204, and is a front and a rear surface of the reinforcing plate 200 connected by the hinge connection part 204.

The hinge of the hinge connecting portion 204 may be selected from any one or more of a generally known hinge, that is, a stainless hinge, a stainless welding hinge, a stainless casting hinge, and a spring hinge. In addition to the above-listed hinges, it will be easily understood by those of ordinary skill in the art that a generally used hinge may be used as the hinge connection part 204.

The hinge connection part 204 may be formed in one of the bent portions of the first reinforcing plate 200 and the second reinforcing plate 200, or may be formed on the entire bent portion, One or more hinge connections 204 may be installed.

When the hinge connection portion 204 is formed in the bent portion of the first reinforcement plate 200 and the second reinforcement plate 200 so that reinforcement is completed in the reinforced concrete member 100, the hinge connection portion 204 May be located at the corner of the reinforced concrete member 100.

At this time, the corner of the reinforced concrete member 100 refers to a straight line seen vertically in the reinforced concrete member 100 shown in FIG. 1, and when the reinforced concrete member 100 is constructed, a line orthogonal to the floor Means.

When the reinforcement plate 200 is installed at the construction site, for example, when the reinforced concrete member 100 is a square reinforced concrete column, as many as four reinforcement plates 200 are installed, each of which has to undergo four construction processes. Although it is inconvenient, when the first and second reinforcing plates are connected by the hinge connection part 204, a large area of the reinforced concrete member 100 can be constructed at once, which shortens the construction time. Convenience of construction can be increased.

In addition, by using the reinforcing plate 200 formed of two plates integrally connected by the hinge connection portion 204 in the bent portion, the edge portion can be continuously and completely reinforced, so that the reinforced concrete member 100 The corners formed by meeting the sides can be completely reinforced.

When the side surface of the rectangular reinforced concrete member 100 is reinforced, when four reinforcing plates 400 corresponding to the cross section corresponding to the side surface are respectively reinforced on the side surface, the side surface and the side surface of the reinforced concrete member 100 The edge portion between the reinforcement is not completed and is exposed, so that additional reinforcement is required. Accordingly, in an embodiment of the present invention, continuity is imparted to the reinforcing plate 200 by using the hinge connecting portion 204 to be reinforced to the corner portion.

In addition, in the reinforced concrete structure reinforced using a reinforcing plate according to an embodiment of the present invention, the coupling member 203 includes the first reinforcing plate 200 and the second reinforcing plate 200 as a hinge connection part 204 ), a fastener 2000 may be installed at one end of each, and a fastener 2200 may be installed at each other end.

At this time, a connection hole 2100 is formed in the fastener 2000 of the fastener 2000 and the fastener 2200 constituting the coupling member 203, and the connection hole 2100 is formed in the fastener. A connection protrusion 2300 corresponding to) is formed to couple the connection hole 2100 and the connection protrusion 2300 so that the coupling member 203 is fastened.

In this case, the connection between the connection protrusion 2300 and the connection hole 2100 may be selected from a combination method such as a press-fitting method or a force-fitting method, and in addition to the above-described coupling method, the connection portion is used as a fastener and a fastener to be fastened. It will be appreciated by those of ordinary skill in the art that various bonding methods of forming and bonding may be used.

The coupling member 203 may be installed and fastened before the step in which the reinforcing plate 200 and the reinforced concrete member 100 are fastened by fastening the bolt and the first nut, or may be installed and fastened later. May be.

In addition, the coupling member 203 may be installed in one or more between the reinforcing plate 200, may be installed to connect all portions between the reinforcing plate 200 and the reinforcing plate 200, It can also be installed to connect parts.

When the coupling member 203 is formed and fastened between the reinforced concrete members 200 to complete reinforcement to the reinforced concrete member 100, the coupling member 203 is It can be located in the corner. The coupling member 203 formed between the reinforcing plates 200 includes a coupling member 203 formed between and fastened between the first reinforcing plate 200 and the second reinforcing plate 200 described above. .

In the reinforcement method of a reinforced concrete structure using a reinforced concrete structure according to the above-described embodiment, the reinforcement plate 200 surrounds the entire circumference of the four sides of the reinforced concrete member 100 (that is, three bent It may be a reinforcing plate 200 having a portion that is formed, and may be a reinforcing plate that surrounds three side surfaces (that is, a reinforcement plate 200 having two bent portions), and that surrounds the two side surfaces. It may be a reinforcing plate (that is, a reinforcing plate 200 having one bent portion) or a reinforcing plate 200 having a shape corresponding to one side surface that does not have a bent portion. It will be understandable. In this case, the bent portion may be formed as a hinge connection part 204.

At this time, between the reinforcing plate 200 and the reinforcing plate 200 reinforced in the reinforced concrete member 100 (for example, between the first and second reinforcing plates) of the reinforced concrete member 100 Corners can be located. At this time, since the edge of the reinforced concrete member 100 has not been reinforced by the reinforcing plate 200, the continuity of reinforcement may be degraded. Therefore, according to an embodiment of the present invention, by installing and fastening the coupling member 203 between the reinforced concrete members 100 to reinforce the corners of the reinforced concrete member 100, the reinforcing plates 200 are connected to each other. I can connect.

According to an embodiment of the present invention, as in the above-described embodiment, as well as preventing the exposure of the corner portions that may be exposed between the reinforcing plate 200 and the reinforcing plate 200, the The reinforcing effect of the reinforcing plate 200 restraining the side surface of the reinforced concrete member 200 is also maximized as the force that pulls one end and the other end of the reinforcing plate 200 to each other is applied by the coupling member 203 Can be.

That is, the coupling member 203 imparts a tension force between the reinforcing plates 200, and restrains the reinforced concrete member 100 of the reinforcing plate 200 by applying a tension force between the reinforcing plates 200. The power to do can be increased. At this time, since the coupling member 203 can be fastened between the reinforcing plates 200 by a relatively easy method such as a press-fitting method or a force-fitting method, the reinforcing plate can be effectively reinforced according to an embodiment of the present invention. I can.

In addition, a part of the fastener 2000 of the coupling member 203 is attached to the reinforcing plate 200 and the other part of the fastener 2000 is included in a part of the fastener attached to the reinforcing plate 200 It can be formed to be folded and unfolded by being connected by a hinged hinge. In this case, a connection hole 2100 is formed in another part of the fastener 2000 to be coupled to and connected to the connection protrusion 2300 formed in the fastener 2200 of the coupling member 203. At this time, the hinge is formed with a spring so that when the fastener 2000 is folded, it may not be easily opened again. Accordingly, when the fastener 2000 is folded and connected to the fastener 2200 , It can be easily prevented from being disconnected.

In this case, the number of coupling members 203 connecting the reinforcement plate 200 and the reinforcement plate 200 may be determined according to the degree of damage to the reinforced concrete member 100.

Hereinafter, embodiments using a reinforcing plate including a spring will be described in the reinforcement construction method of a reinforced concrete structure using a reinforcing plate of the present invention with reference to FIGS. 7 to 10.

7 is a view showing exemplary configurations in which elastic members are arranged in anchors in the reinforcement method and reinforcement structure of a reinforced concrete structure using a reinforcing plate according to a third embodiment of the present invention, and FIG. In the reinforcement method and reinforcement structure of a reinforced concrete structure using a reinforcing plate according to the fourth embodiment of the present invention, it is a view exemplarily showing a configuration in which a bolt and a nut, an elastic member, and a nut cap for preventing nut loosening are arranged. 9 is a diagram illustrating a method of applying a reinforcement method of a reinforced concrete structure using a reinforcing plate to a structure according to a fourth embodiment of the present invention, and FIG. 10 is a third embodiment and a fourth embodiment of the present invention. In an embodiment, it is a view showing an example of a reinforcement method of a reinforced concrete structure using a reinforcing plate in which a coupling member is installed is applied to the structure.

In FIGS. 7 to 10, the reinforced concrete member 100 is described as an example as a square reinforced concrete column. However, the reinforced concrete member 100 is not limited to a column, and may include all reinforced concrete members of various shapes such as a reinforced concrete beam or slab having various cross-sectional shapes such as a circle.

As shown in Figure 7, the concrete structure 30 by the reinforcement method of a reinforced concrete structure using a reinforcing plate of the present invention is a reinforced concrete member 100, a reinforcing plate 200 and an anchor 110 for fastening them, bolts (120), the coupling member 203 connecting between the first nut 130 and the first spring 140, and the reinforcing plate 200 and a hinge connection formed on the bent portion of the reinforcing plate 200 ( 204).

7 shows an example in which an anchor having a female threaded portion formed therein is used as an example of an anchor. Therefore, it is possible to fix the reinforcing plate by fastening a separate bolt, for example, a computerized bolt to the female threaded portion. If a bolt is pre-fastened to the anchor or an anchor of a type (for example, an anchor bolt) is used, the bolt provided with the anchor can be used, or the provided bolt can be replaced. It is possible to perform the reinforcement method of the present invention by using another bolt.

Therefore, depending on the type of anchor used, a bolt 120 that is previously fastened to the anchor 110, such as an anchor bolt, may be used, and a separate bolt 120 conforming to the standard of the anchor 110, for example It will be appreciated by those skilled in the art that it is also possible to use a computational bolt.

Hereinafter, for clarity, the direction in which the anchor 110 is buried in the anchor receiving part 101 is referred to as a downward direction (lower, lower) of the anchor or bolt, and the bolt 120 fastened to the anchor 110 The direction in which) is connected to the reinforcing plate 200 will be described by referring to the upward direction (top, top) of the anchor or bolt.

The first spring 140 is installed on the outer periphery of the bolt 120 from the top of the anchor 110. The first spring 140 may be installed after filling the anchor 110 or after fastening the bolt 120 to the anchor 110. That is, before fastening the reinforcing plate 200 to the bolt 120, the first spring 140 is first positioned on the reinforced concrete member 100. Then, the reinforcing plate 200 is fastened and the first nut 130 is tightened so that the first spring 140 abuts the reinforcing plate 200.

The first spring 140 is a reinforcing plate that is located inside the reinforced concrete member 100 and is attached to the reinforced concrete member 100 as a reinforcing material for vibration applied to the reinforced concrete member 100 and the expansion and contraction force of the concrete. It can be delivered effectively to (200). As such, since the first spring 140 is in close contact with the reinforcing material inside the concrete, the force and vibration acting on the concrete structure are absorbed by the elastic member and transmitted to the reinforcing material, thereby improving the reinforcing effect by the reinforcing material.

In addition, the first spring 140 may distribute the force received by the anchor 110 embedded in the reinforced concrete member 100. The anchor 110 and the bolt 120 embedded in the reinforced concrete member 100 are constantly receiving force due to vibration, shock, expansion, contraction, etc. of the concrete. A phenomenon in which the bonding between the concrete members 100 becomes loose may occur. The first spring 140, which is an elastic member, absorbs and disperses this force. Therefore, it is possible to prevent the anchor 110 and the bolt 120 from being suddenly released or damaged by an external force such as vibration, so that the reinforcing plate 200 is separated from the reinforced concrete member 100.

In order to install the first spring 140 having such an effect, after forming the anchor receiving portion 101 on the outer surface of the reinforced concrete member 100, the first spring receiving portion ( 102) can be further formed. In this case, the diameter d _s1 of the first spring accommodating portion 102 may be formed to be greater than or equal to _{the diameter d a} of the anchor accommodating portion 101. Therefore, in one embodiment of the present invention, when the anchor receiving portion 101 is formed, the reinforced concrete member 100 is formed by the sum of the embedded length (L) of the anchor 110 and the length (l) of the first spring 140. A groove is dug from the outer surface, but at this time, the diameter is formed to a size capable of accommodating the anchor 110 (d _a ), and the diameter (d _s1 ) of the first spring receiving part 102 is determined by the anchor receiving part 110. When it is desired to form larger than the diameter (d _a ), the first spring is equal to the length (l) of the first spring 140 from the outer surface of the reinforced concrete member 100 at the position where the anchor receiving portion 110 is formed. _{A groove having a diameter d s1} of the receiving portion 102 may be additionally formed.

The size of the first spring 140, that is, a diameter, a thickness, and a length may be appropriately selected as necessary.

In addition, since the bolt 120 is installed through the inside of the first spring 140, the bolt 120 serves as a guide to prevent the first spring 140 from being bent or bent.

In addition, a first spring protection part 170 may be added to the first spring receiving part 102. The first spring protection part 170 is to prevent foreign substances such as concrete pieces from being pinched in the first spring 140, and is a cylindrical member installed in accordance with the diameter of the first spring receiving part 102 or in concrete. It may be a coating layer to which the used paint is applied.

The bolt 120 is installed by penetrating the inner diameter of the first spring 140, and then the bolt 120 is passed through the through hole 210 of the reinforcing plate 200 to pass the reinforcing plate 200 to the reinforcing bar. It is fixed to the concrete member 100. When there are a plurality of through-holes formed in one reinforcing plate 200, the reinforcing plate is positioned so that the plurality of through-holes are fastened with corresponding bolts.

The reinforcing plate 200 may be a steel plate or a steel plate used in a general steel plate reinforcement method. However, it is not limited thereto, and steels that can be attached to concrete for repair and reinforcement of concrete structures, such as section steel (H-type, L-type, etc.), FRP reinforcing plate (for example, carbon fiber plate, aramid fiber plate, glass fiber plate), etc. It may include. In addition, the self-weight, size, and thickness of the reinforcing material may be determined according to the degree of damage to the concrete structure and the degree of reinforcement thereto.

Therefore, the reinforcing plate 200 may be formed in one single layer or in one or more multi-layered structures depending on the degree of reinforcement. If necessary, it may be formed in a structure in which functional fibers or plastic sheets (eg, carbon fibers, aramid fibers, glass fibers, etc.) are laminated together.

The first nut 130 is fastened to the bolt 120 so that the reinforcing plate 200 located on the outer surface of the reinforced concrete member 100 can be firmly fastened, and the first nut 130 is fastened.

A washer (not shown) for preventing the nut from loosening may be included between the first nut 130 and the reinforcing plate 200. For example, washers such as plain washers, spring washers, rubber washers, etc. may be used.

In general, in a fastening method using a bolt and a nut, there is a possibility that elasticity is lost due to a yield phenomenon of a material, or a space is generated due to vibration of a fastening structure and a component, and the frictional force between the bolt and the nut is reduced, thereby causing loosening. In order to prevent an accident due to this loosening phenomenon, in the prior art, a method of fixing the bolt and nut by injecting an adhesive is used, but there is a problem that the nut must be destroyed when the nut needs to be disassembled for maintenance. .

FIG. 7 relates to an embodiment in which the first spring 140 is added to the configuration described above in FIGS. 4 to 6, and descriptions of configurations and methods that are applied in the same manner to FIGS. 4 to 6 will be omitted. Similarly, it will be appreciated that the method in which the reinforcing methods and configurations of FIGS. 4 to 6 are applied to the concrete structure may be applied in a manner similar to the exploded perspective view of FIG. 9 to the configurations indicated by the same reference numerals in FIGS.

The reinforcing method and structure according to an embodiment of the present invention is to prevent loosening while convenient construction by additionally installing a second spring 150 and a second nut 160 on the first nut 130. It is characterized. The configuration of such an embodiment will be described in detail below with reference to FIGS. 8 and 9.

As shown in Figure 8, the concrete structure 30 by the reinforcement method of a reinforced concrete structure using a reinforcing plate of the present invention is a reinforced concrete member 100, a reinforcement plate 200 and an anchor 110 for fastening them, bolts (120), the coupling member 203 connecting between the first nut 130 and the first spring 140, and the reinforcing plate 200 and a hinge connection formed on the bent portion of the reinforcing plate 200 ( 204), and may include a second spring 150, a second nut 160, and a nut cap 300.

9 is an exploded perspective view illustrating a method in which the configuration of FIG. 8 is applied to a structure, and the reinforced concrete member 100, reinforcement plate 200 and anchors 110 and bolts for fastening them described above in FIG. 8 120), a coupling member 203 connecting between the first nut 130 and the reinforcing plate 200, a hinge connection part 204 and a first spring 140 and a second spring 150, and a second nut ( 160) and the reinforcing method of the embodiment including the nut cap 300 may be applied to the structure as shown in FIG. 9.

FIG. 8 relates to an embodiment in which a second spring 150, a second nut 160, and a nut cap 300 are added to the configuration described above in FIG. 7, and the configuration is applied in the same manner to FIGS. 7 and 8 The description of the method and the like will be omitted. Similarly, it will be appreciated that the method in which the reinforcing method and configuration of FIG. 7 is applied to the concrete structure may be applied in a manner similar to the exploded perspective view of FIG. 9 to the configurations indicated by the same reference numerals in FIGS. 7 to 9.

Fastening the first nut 130 to the bolt 120, and placing the second spring 150 and the second nut 160 on the bolt 120 protruding above the first nut 130 in order Let it. At this time, as in the first spring 140, since the bolt 120 is installed through the inside of the second spring 150, the bolt 120 prevents the second spring 150 from bent or bent. You will act as a guide.

The second spring 150 is located between the first nut 130 and the second nut 160, so that one end of the second spring 150 abuts the first nut 130, and the second spring The other end of 150 is positioned in a contact shape with the second nut 160. A first fixing groove 131 and a second fixing groove 161 are formed in the first nut 130 and the second nut 160, respectively, so that a second spring 150 is formed in the fixing grooves 131 and 161. Both ends of) are positioned in a seated shape.

In an example of the present invention, when the first nut 130 rotates in the loosening direction, the second spring 150 having one end located in the first fixing groove 131 of the first nut 130 rotates in the open direction. That is, it may be installed so that the second spring 150 is relaxed. Therefore, one end in contact with the first nut 130, that is, the lower end of the second spring 150, in the direction in which the second spring 150 is opened by the loosening energy acting in the direction in which the first nut 130 is released. When it is attempted to rotate, the other end of the second nut 160 in contact with the second fixing groove 161, that is, the upper end of the second spring 150 is between the second nut 160 and the second spring 150 As the rotation of the second nut 160 is prevented by the frictional force acting on the second spring, the loosening energy is generated by the restoring force of the second spring 150 that is about to rotate or partially rotated in the opening direction. ) Is transmitted in a direction in which the second spring 150 is retracted, so that loosening of the first nut 130 may be prevented.

Accordingly, the second spring 150 presses the first nut 130 from the top of the first nut 130 to prevent the first nut 130 from being released due to vibration or the like. In addition, the second spring 150 absorbs the vibration transmitted through the reinforcing plate 200, the bolt 120, and the nuts 130, 160 by the elastic member and simultaneously presses it from the top of the first nut 130. The frictional force is increased compared to when the first nut 130 is used alone, so that rotation of the first nut 130 may be prevented.

In addition, a nut cap 300 may be additionally installed to prevent and physically fix the bolt 120 and the first and second nuts 130 and 160 from rotating. The nut cap 300 is formed to accommodate the first and second nuts 130 and 160, the second spring 150 and the bolt 120.

The nut cap 300 may also block moisture and dust from the external environment to prevent the bolt 120, the first and second nuts 130 and 160, and the second spring 150 from rusting. . In this way, the life extension effect of the bolts 120, nuts 130 and 160, and the second spring 150 may be maximized.

According to the reinforcing method and the reinforcing structure of the present invention, welding and the use of adhesives are minimized, so that maintenance and repair of the reinforcing structure is easy even after reinforcement. That is, since the reinforcing plate 200 is welded or the reinforcing plate 200 and the concrete member 100 are not bonded with epoxy, the nut cap 300 is separated from the reinforcing structure whenever necessary. And only some of the reinforcing structures, such as the second springs 140 and 150, the first and second nuts 130 and 160, the bolts 120, and the reinforcing plate 200, which have problems, can be repaired and replaced. Management costs can also be reduced.

In particular, bolts and nuts may expand or contract not only due to vibrations such as earthquakes, but also due to changes in ambient temperature, resulting in screw loosening. However, according to the reinforcing method and the reinforcing structure of the present invention, since maintenance and repair are easy, bolts and nuts can be refastened without dismantling the entire reinforcing structure.

10 is a reinforced concrete member 100 in the case of including the coupling member 203 and the hinge connection part 204 among the various embodiments, the reinforcing plate 200 (hereinafter, having a hinge connection part 204 on the bent part) When the reinforcement of (including the reinforcing plate 200) is completed, a diagram showing an embodiment in which the fastener 2000 and the fastener 2200 of the coupling member 203 are fastened.

Hereinafter, an embodiment of a reinforcing method using a first wire, a second wire, and a reinforcing plate among the reinforced concrete structure reinforcing methods using wires and reinforcing plates of the present invention will be described with reference to FIGS. 11 to 13.

It is a view showing an example of a reinforcing plate formed with a protruding insertion portion for receiving a 2-wire. 12 is a view showing a reinforcing plate installed on an outer surface of a reinforced concrete member in which the first and second wires are installed in the reinforcement construction method and reinforcement structure of a reinforced concrete structure using a reinforcing plate according to a fifth embodiment of the present invention. Figure 13 is an exemplary view, and in the reinforcement method and reinforcement structure of a reinforced concrete structure using a reinforcing plate according to a fifth embodiment of the present invention, the outside of the reinforced concrete member in which the first wire and the second wire are installed. It is a diagram showing an example of installation on a reinforcing plate by a bolting method on the surface.

In FIGS. 11 to 13, the reinforced concrete member 100 has been described as an example as a square reinforced concrete column. However, the reinforced concrete member 100 is not limited to a column, and may include all reinforced concrete members of various shapes such as a reinforced concrete beam or slab having various cross-sectional shapes such as a circle.

As shown in Figure 11, the concrete structure 50 by the reinforcement method of a reinforced concrete structure using a wire and a reinforcing plate of the present invention is a reinforced concrete member 100, a reinforcing plate 200, a first wire 11, A wire binding member (15) for binding both ends of the first wire, a second wire (12), a wire connecting member (16) connecting both ends of the first wire and the second wire, the first wire and the first wire The first wire protection member 13 and the second wire protection member 14 to protect the 2-wire, the coupling member 203 connecting between the reinforcing plate 200 and the bent portion of the reinforcing plate 200 It may be configured to include a hinge connection portion 204 to be formed.

11 is a portion connected to the reinforcing plate 200, the protruding insert 201 for accommodating the first and second wires, and the first and second wires in the configuration described above in FIGS. 1 to 3 It relates to an embodiment in which an observation part 202 capable of observing, a coupling member 203 connecting between the reinforcing plates, and a hinge connection part 204 formed on a bent portion of the reinforcing plate 200 are added, A description of the configuration and method applied equally to FIGS. 1 to 3 will be omitted.

In one embodiment of the present invention, the reinforced concrete member 100 is a first wire 11, a second wire 12, a first wire protection member 13, a second wire protection member 14, a wire binding member In the reinforced concrete structure reinforced with (15) and the wire connecting member (16), the reinforced concrete member (100) in which the first wire (11) and the second wire (12) are installed is covered with a reinforcing plate (200). . In this case, the reinforcing plate 200 may be formed in a shape corresponding to the shape of the reinforced concrete member 100 to which the aforementioned member is reinforced. That is, to accommodate the first wire 11, the second wire 12, the first wire protection member 13, the second wire protection member 14, the wire binding member 15 and the wire connecting member 16. The first wire 11, the second wire 12, the first wire protection member 13, the second wire protection member 14, the wire binding member 15, and the wire connection member 16 so as to include a space that can be used. A protruding insertion portion 201 may be formed at a position corresponding to the portion where) is located.

A first wire 11, a second wire 12, a first wire protection member 13, a second wire protection member 14, a wire binding member 15 and a wire connecting member in the protruding insert 201 By positioning (16), close contact between the reinforcing plate 200 and the reinforced concrete member 100 and close contact between the reinforcing plate 200 and the wire 11 and the wire protection member 12 can be effectively achieved at the same time.

In addition, an observation part 202 may be additionally formed in the protruding insertion part 201. The observation part 202 is made of a high-strength plastic having high light transmittance in a through hole formed in the protruding insertion part 201 or a high-strength plastic, so that the inside of the reinforcing plate can be observed. Through the first wire 11 and the second wire 12 can be observed with the naked eye a state and a fastening state, more preferably a fastening state in the wire connection member 16. In the conventional steel plate reinforcement method, even if deformation, separation, peeling, etc. occur in the reinforced concrete member 100, it is difficult to determine the state of the reinforced structure because the internal structure cannot be visually checked. , For example, there is a problem in that some or all of the reinforcing plate 200 must be removed. In addition, in the conventional reinforcing method, it is difficult to form a separate through hole in the reinforcing plate 200 because the reinforcing performance is determined by the degree of adhesion and attachment between the reinforced concrete member 100 and the reinforcing plate 200.

However, in the present invention, the reinforced concrete member 100 is reinforced by using the first wire 11 and the second wire 12, and the protrusion for accommodating the first wire 11 and the second wire 12 Since the reinforcing performance of the insertion part 201 is complementary, even if the observation part 202 is formed on the protruding insertion part 201, the first wire 11 and the second wire 12 are not significantly degraded. ), it is possible to visually check the fastening state and deformation.

Therefore, in FIGS. 11 to 13, the observation portion 202 is shown to be formed on the reinforcement plate 200 coupled to one surface of the reinforced concrete member 100 on which the wire connection member 16 is located, but the observation portion ( 202) will be understood by those skilled in the art that the shape, size, number, location, and the like are not limited to those shown, and various modifications are possible as necessary.

As shown in Figure 4, the reinforcing plate 200 includes the first reinforcing plate 200 and the second reinforcing plate 200, and the first reinforcing plate 200 is the reinforced concrete shown in FIG. Between two consecutive sides of the member 100, the reinforced concrete member 100 may be bent to correspond to the shape of a cross-section corresponding to the side surface of the reinforced concrete member 100 to form a “b” shape, and the second reinforcing plate 200 may also be formed of the reinforcing bar. Between the remaining two consecutive sides of the concrete member 100, the reinforced concrete member 100 may be bent to correspond to the shape of the cross-section corresponding to the side surface of the reinforced concrete member 100 to form a "b" shape.

In an embodiment of the present invention, as shown in FIG. 13, the reinforcing plate 200 is fastened to the reinforced concrete member 100 corresponding to the reinforcing plate 200 in a bolting manner, so that the reinforcing plate 200 and the reinforced concrete member ( 100), the first wire (11), the second wire (12), the first wire protection member (13), the second wire protection member (14), the wire binding member (15) and the wire connecting member (16) are integrated You can do it. That is, the above-described various bolting and wire crimping method is a bar that can be applied as a single reinforcing method and structure, which is illustrated in FIG. 13.

13 is a combination of various embodiments of the present invention, in which the wire crimping method of FIGS. 1 to 3 and the bolting crimping method of FIGS. 8 to 9 are applied together. Referring to the perspective view, the configuration and reinforcement method of this embodiment will be sufficiently understood by those skilled in the art.

A protruding insertion part 201 is formed at the position of the reinforcing plate 200 corresponding to the portion surrounding the first wire 11 and the second wire 12 on the reinforced concrete member 100, and the first wire 11 ) And the reinforced concrete member 100 where the second wire 12 is not enclosed, an anchor insertion portion 101 is formed, and a through hole 210 is formed at the corresponding position of the reinforcing plate 200. The reinforcing plate 200 is fixed to the reinforced concrete member 100 by bolting compression.

At this time, since each of the reinforcing plates 200 is attached using a bolt fastening method on each outer circumferential surface of the reinforced concrete member 100, excessive It is not necessary to use an epoxy adhesive or surface welding between the reinforcing plate 200 and the reinforcing plate 200 at the corners.

At this time, when the side surface of the rectangular reinforced concrete member 100 is reinforced when reinforcing the reinforced concrete member 100 by the above-described bolting method, each of the four reinforcing plates corresponding to the side surface is reinforced so that the side surface and the side surface of the reinforced concrete member 100 The edge portion between the reinforcement is not completed and is exposed, so that additional reinforcement is required. That is, there may be a need to reinforce the circumference of the reinforced concrete member 100 without gaps by continuously reinforcing the reinforcement plate 100 including the corner portions. Accordingly, an embodiment of the present invention uses the reinforcing plate 200 in which a portion corresponding to the edge portion is bent so as to be reinforced to the edge portion, and the reinforcing plate 200 is formed including a hinge connection portion at the bent portion. It has this continuity and can be configured to be reinforced.

In addition, in the case of installing the reinforcement plate 200 at the construction site, for example, when the reinforced concrete member 100 is a square reinforced concrete column, as many as four reinforcement plates 200 are respectively installed, four construction processes are performed. Although there is an inconvenience that must be passed, when the first and second reinforcement plates are constructed, a large area of the reinforced concrete member 100 can be constructed at once, so that the construction time can be shortened and the convenience of construction can be increased. .

Therefore, in an embodiment of the present invention, the corner portion can be completely and continuously reinforced by using the reinforcing plate 200 in which the hinge connection portion 204 is formed at the bent portion, so that the continuous side surface of the reinforced concrete member 100 The edges formed by this meeting can be reinforced without any gaps.

At this time, in the case of simply using the bent reinforcing plate, there may be inconvenience in that the member occupies a large area of the construction site because it is formed in an a-shape. Storage is possible. In addition, a pulling force is applied between the first reinforcing plate and the second reinforcing plate by the hinge connection part 204 formed in the bent portion, so that a tension force may be imparted.

In the prior art, when a steel plate is to be attached on each side, such as a concrete column, a method of separately welding the steel plate and the steel plate at the edge of the column is used without bolting the column and the steel plate. Surface welding between the steel plate and the steel plate has a disadvantage in that it takes a considerable amount of time, and the quality of the welding part is very large depending on the skill level of the worker. In particular, in the case of steel plate reinforcement, high-strength CO ₂ welding is performed _{instead of general welding to improve the reinforcement performance. Such CO 2} gas welding has a constant welding rate and high tensile strength compared to arc welding, but skilled techniques are used. It is a major disadvantage that the construction cost and time are increased because it is required.

However, in the present invention, the concrete column and the reinforcing plate are bolted to each other, and two or more reinforcing plates are connected by a hinge connection and a coupling member is installed. Quality fluctuations according to skill level are also small, so you can expect a certain level of strength.

In the reinforcement method of a reinforced concrete structure using a wire and a reinforcing plate according to the above-described embodiment, the reinforcing plate 200 surrounds the entire circumference of the four sides of the reinforced concrete member 100 (ie, three It may be a reinforcing plate 200 having two bent portions), and may be a reinforcing plate that surrounds three sides (that is, a reinforcing plate 200 having two bent portions). It may be a reinforcing plate (ie, a reinforcing plate 200 having one bent portion) or a reinforcing plate 200 having a shape corresponding to one side surface that does not have a bent portion. It will be easy to understand. In this case, the bent portion may be formed as a hinge connection part 204.

Hereinafter, an embodiment of a reinforcing method of a reinforced concrete structure using a first wire and a second wire of the present invention will be described with reference to FIG. 14.

14 is a reinforcement method and reinforcement structure of a reinforced concrete structure using a first wire and a second wire according to a sixth embodiment of the present invention, after the reinforcing plate is installed on the outer surface of the reinforced concrete member, the first wire and the second wire This is an exemplary diagram showing a two-wire installation.

In FIG. 14, the reinforced concrete member 100 has been described as an example as a square reinforced concrete column. However, the reinforced concrete member 100 is not limited to a column, and may include all reinforced concrete members of various shapes such as a reinforced concrete beam or slab having various cross-sectional shapes such as a circle.

14 relates to an embodiment in which a reinforcing plate 200, a coupling member 203, a hinge connection part 204, a wire cover 205, and the like are added to the configuration described above in FIGS. 1 to 3, and FIGS. 11 to 13 In the above-described configuration, since the protrusion insert 201 is not included, and the wire cover 205 is related to an embodiment that further includes, a description of the configuration and method applied in the same manner in FIGS. 1 to 3 and 11 to 13 I will omit it.

In one embodiment of the present invention, after the reinforcement plate 200 is first reinforced on the reinforced concrete member 100, the first wire 11 and the second wire 12 are formed on the outer surface of the reinforced concrete member 100. , The first wire protection member 13, the second wire protection member 14, the wire binding member 15, and the wire connection member 16 may be installed.

11 to 13 of the present invention, the first wire 11, the second wire 12, the first wire protection member 13, the second wire protection member 14, the wire binding member ( 15) and the wire connection member (16) and then reinforcing the reinforcing plate (200) to protect the first wire (11), the second wire (12), the first wire protection member (13), the second wire A portion of the reinforcing plate corresponding to the member 14, the wire binding member 15 and the wire connecting member 16 is formed as a protruding insert, so that the reinforced concrete member 100 can receive reinforcement by the reinforcing plate. There will be no. Therefore, when the reinforced concrete structure reinforcement method using the first wire and the second wire according to an embodiment of the present invention is applied to the structure, all outer surfaces of the reinforced concrete member 100 are reinforced by the reinforcing plate, and additionally Since the reinforcement is performed by the first wire and the second wire, it can be seen as an embodiment in which the area of reinforcement is further expanded in the embodiment of the present invention.

At this time, it will be easily understood by those skilled in the art that the reinforcement plate 200 may be attached to the reinforced concrete member 100 by epoxy or by a bolting method.

In addition, since the first wire and the second wire on the outer surface of the reinforcing plate 200 are exposed to the outside, there is a risk of being damaged by friction, etc., so that a wire cover 205 for protecting the first wire and the second wire is exposed to the outside. Corresponds to the first wire (11), second wire (12), first wire protection member (13), second wire protection member (14), wire binding member (15) and wire connection member (16) on the surface It can be installed in the shape of a protruding insert.

In this case, the wire cover 205 may be additionally provided with an observation unit 202. The observation unit 202 is made of a through hole formed in the wire cover 205 or a high-strength plastic having high light transmittance in the wire cover 205 so that the aforementioned member located in the wire cover 205 can be observed. In part, the state and the fastening state of the first wire 11 and the second wire 12, more preferably, the fastening state in the wire connecting member 16 can be observed with the naked eye. In the conventional steel plate reinforcement method, even if deformation, separation, peeling, etc. occur in the reinforced concrete member 100, it is difficult to determine the state of the reinforced structure because the internal structure cannot be visually checked. , For example, there is a problem in that some or all of the reinforcing plate 200 must be removed. In addition, in the conventional reinforcing method, it is difficult to form a separate through hole in the reinforcing plate 200 because the reinforcing performance is determined by the degree of adhesion and attachment between the reinforced concrete member 100 and the reinforcing plate 200.

However, in the present invention, since the reinforcement plate 200 is reinforced by a separate wire, even if a separate observation unit 202 is formed on the wire cover 205, the first wire 11 does not deteriorate the reinforcing performance. ) And the fastening state and deformation of the second wire 12 can be visually checked.

Therefore, in FIG. 14, the observation portion 202 is shown to be formed on the wire cover 205 coupled to one surface of the reinforcing plate 200 on which the wire connection member 16 is located, but the observation portion 205 is It will be understood by those of ordinary skill in the art that the shape, size, number, location, etc. are not limited to what is shown, and various modifications are possible as necessary.
