Description

{REINFORCEMENT METHOD OF CONCRETE STRUCTURE USING A FIRST WIRE AND A SECOND WIRE}

The present invention relates to a reinforced concrete structure, and more particularly, to a method of reinforcing a reinforced concrete structure using a first wire and a second wire.

Structures are damaged or aged due to various factors. The recent earthquakes in Gyeongju and Pohang increased the risk of damage to structures. In particular, for piloti structures without walls on the first floor, the risk of damage to the structure due to earthquakes is greater because the first floor is a vulnerable floor. Therefore, repair and reinforcement are required in order to extend the physical life of the damaged or aged structure by improving the strength and to exhibit its original function.

In particular, in the case of reinforced concrete columns, lateral reinforcing bars that adequately confine concrete are not used enough in many cases, so that lateral deformation of the columns occurs easily during earthquakes, which leads to brittle fracture.

There are various methods for reinforcing the reinforced concrete structure to compensate for this, but in general, a method of attaching a member with high ductility such as a steel plate to the structure 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 loads and leading to ductile behavior of the reinforced concrete structure. This has a great advantage in that the construction period is short and can be applied to structures in use, but there is a problem that peeling and dropping of the reinforcing material may occur because the parent body and the reinforcing material are attached rather than integral.

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

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

In addition, the reinforcement method of adhering a reinforcing 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 reinforcing material is adhered. This is to increase the adhesion of the epoxy, and it is performed over a more complex step than the general surface treatment step. Since this surface treatment is performed using a grinder and sandpaper, etc., a lot of dust is generated, so there is a problem that it is difficult to treat the dust depending on the working environment. .

In addition, in the reinforcement method of adhering a reinforcement to the surface of a reinforced concrete structure using an adhesive such as an epoxy resin, an epoxy-based adhesive is injected to a certain thickness for integration of the concrete and the reinforcement, and is cured and compressed. However, curing the epoxy takes a considerable amount of time and causes shrinkage of the epoxy. Therefore, it is difficult to directly observe the structure of the adhesive interface between the surface of the structure and the reinforcing material, so it is difficult to identify cracks in the concrete, and there is a problem that unexpected accidents may occur because it is not possible to accurately check whether the reinforcing material is peeled.

In particular, it is widely known that epoxy-based adhesives contain combustible materials and have an environmental problem of generating toxic gases while burning in case of fire. Recently, social demand for eco-friendly construction methods has continuously increased even in construction sites, and accordingly, the need for reinforcement construction methods for reinforced concrete structures to replace epoxy adhesives is emerging.

More specifically, the present invention proposes a crimping method using bolting and a reinforcing method of a crimping method using a wire, preferably in the case of the damaged state 1 to 3, the crimping method using the bolting, and the damaged state 4 and 5. It is proposed to apply a compression 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 needed, and may be applied together. Hereinafter, an embodiment of a method of reinforcing 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 view exemplarily showing a method in which a reinforcement method of a reinforced concrete structure 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, in the reinforced concrete structure using the first wire and the second wire according to the first embodiment of the present invention, the first wire is bound and the first wire and the second wire are connected to the surface (wire in Figure 1) It is a view exemplarily showing the opposite surface of the binding member 15), and FIG. 3 is a reinforced concrete structure using a first wire and a second wire according to the first embodiment of the present invention, the first It is a view exemplarily showing that the wire is bound by the wire binding member and the first wire and the second wire are connected by the wire connecting member.

As shown in Figure 1, the concrete structure 10 by 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 (confining) 11), the second wire 12, the first wire protection member 13, the second wire protection member 14, the wire binding member 15, and may be configured to include a wire connection member (16).

1 to 3, the reinforced concrete member 100 has been described as an example of a rectangular reinforced concrete column. However, the reinforced concrete member 100 is not limited to a column, and may include all types of reinforced concrete members of various types such as reinforced concrete beams or slabs having various cross-sectional shapes such as circular.

The first wire 11 and the second wire 12 can be reinforced stronger than when reinforcing with one wire by restoring the deformation or stress of the existing structure by installing two wires, and by restraining the concrete to concrete. It can lead to the improvement of the bearing capacity by delaying the damage of the 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 made by collecting a general wire rope, that is, a wire, and winding it around a core at a constant pitch to form a strand. 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 perimeter of the reinforced concrete member 100 and both ends are fastened, the first wire 11 and the second wire 12 are tensioned. A post tension is introduced into the reinforced concrete member 100 .

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

More specifically, in one example of the present invention, in order to prevent breakage of the first wire 11 and the second wire 12 at the edge of the reinforced concrete member 100, the first wire protection member 13 and the second 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 penetrate therein. am. By installing the first wire protection member 13 and the second wire protection member 14, the edge of the reinforced concrete member 100 and the first wire 11 and the second wire 12 are prevented from coming into direct contact. Thus, it is possible to avoid damage or breakage of the first wire 11 and the second wire 12 due to abrasion caused by the edges.

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

At this time, the first wire protection member 13 and the second wire protection member 14 are positioned at the corners of the reinforced concrete member 100 to protect the wire from the first wire and the second wire from being abraded. and the wire binding member 15 is a member for binding the first wire, and the wire connecting member 16 is the first wire 11 passing through the wire binding member 15 and is bound when the first wire is bound. 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, whenever a pair of the first wire and the second wire is put on the reinforced concrete member 100, the first wire protection member Four (13), the second wire protection member 14 is four, the wire binding member 15 is one, the wire connecting member 16 may be installed two.

At this time, the first wire protection member 13 and the second wire protection member 14 are at the edge of the reinforced concrete member 100 viewed in the longitudinal direction in FIG. 1 , the wire binding member 15 and the The wire connection member 16 may be located on one of the four side surfaces of the reinforced concrete member 100 around which the first wire 11 and the second wire 12 are transversely surrounded.

In one embodiment of the present invention, the first wire 11 is surrounded by the reinforced concrete member 100 in the cross-sectional direction and four first wire protection members located at the four corners of the reinforced concrete member 100, respectively. It can pass through both ends of (13). The first wire 11 passing through the first wire protection member 13 installed at the edge of the reinforced concrete member 100 passes through the first wire protection member 13 and does not fall down the reinforced concrete member. It is located surrounded by ( 100 ), but since both ends of the first wire 11 are not fastened, it may be in a state in which no tension is applied.

Therefore, by fastening both ends of the first wire 11 passing through the first wire protection member 13, the wire binding member 15 may be installed to impart tension to the first wire 11. . The wire binding member 15 may be fastened to the first wire 11 reinforced in the reinforced concrete member 100 so that continuous tension can be maintained, and the first wire protection member 13 is the first wire The effect of the wire binding member 15 can be supplemented so that the (11) tension can be maintained.

At this time, the wire binding member 15 for binding both ends of the first wire may have two through-holes in the upper and lower portions of the wire binding member 15 . One of the four side surfaces of the reinforced concrete member 100 in which both ends of the first wire 11 that is surrounded in the cross-sectional direction and passed through the first wire protection member 13 are rectangular in the reinforced concrete member 100 When meeting in , one end of both ends of the first wire 11 passes through a through hole located at an upper portion of the through holes formed above and below the wire binding member 15, and the other end of both ends of the first wire 11 is The wire binding member 15 may pass through a through hole located in the lower portion.

At this time, both ends of the first wire 11 are formed using a generally known terminal processing method of wire rope, that is, at least one of a socket, a thimble, a wedge, an ice pliers, and a clip, and the wire binding when formed The size of the finishing material (sleeve) for fixing both ends of the first wire 11 in a ring shape is larger than the size of the through hole of the member 15, so that the first wire 11 is attached to the wire binding member 15. ) can be bound.

At this time, in the terminal processing method of the wire rope, the socket is made by putting the end of the wire rope in 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. It is a member that is fitted so that the inside of the ring is not worn by holding it down, and the wedge is a kind of wedge, and the rope is wound around the wedge and pressed into the case to form the end of the wire rope by binding it. It refers to binding the wire rope terminal with a ring by bending it to form a shape like a thick ring. In addition, wire rope termination using a clip can be made using a U-shaped bolt when fixing the wire rope. It will be readily understood by those skilled in the art that, in addition to the above-listed terminal processing method of the wire rope, a terminal processing method of a generally known wire rope can be used.

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

At this time, the first X-shape may be formed as in the surface (the 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. 1, 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 surface where the wire binding member 15 is visible).

And the wire connecting member 16 is installed at both ends of the processed first wire 11 to connect both ends of the second wire 12 . At this time, the wire connecting 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 the form of an O-type lying down, so that the wire can be caught on both sides. Turn the nut to connect one end of the male thread to connect both ends of the wire. The turnbuckle has a screw rod on the left and right, and the threaded part is connected with a common nut. An eye bolt is a bolt with a hook on the head. It will be readily understood by those skilled in the art that in addition to the method of fastening both ends of the wire rope listed above, a method of fastening both ends of a generally known wire rope can be used.

As shown in Fig. 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 the stress in various directions of the reinforced concrete member 100 to prevent deformation in various directions to reinforce one wire or reinforce two wires in parallel. It is possible to reinforce the reinforced concrete member 100 more effectively than when.

That is, in the case of reinforcing 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 in the cross-sectional direction occurs, but in one embodiment of the present invention and Likewise, when the two wires overlap in an X-shape on two of the side surfaces of the reinforced concrete member 100, reinforcement is possible with the force in the diagonal direction on the two surfaces, and reinforcement with the force in the cross-section direction on the other two surfaces This makes it possible to reinforce with forces in various directions.

In this way, when the wire is reinforced to form an X-shape, one wire from the bottom to the top and the other wire from the top to the bottom on one side between the two continuous corners (meaning the vertical line shown in FIG. 1) In addition to the diagonal direction in which the wire is reinforced by being wrapped around it, reinforcement is also possible in the x-axis and y-axis directions in which the diagonal force is decomposed.

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

The conventional reinforced concrete member reinforcement method has a problem that the reinforcement area is insufficient because reinforcement is possible only for a certain area of the reinforced concrete member 100 by reinforcing it in the cross-sectional direction. Reinforcement in various directions is possible by the first wire 11 and the second wire 12, and at this time, a pair of first wire protection members 13 and second wires installed at each corner of the reinforced concrete member 100 When the two-wire protective member is installed to be spaced apart from each other, the first wire 11 and the second wire 12 are positioned farther from the edge, so that the X-shaped overlapping shape can be further increased. That is, there is an advantage that the area to be reinforced can be determined according to the interval 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 by 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 present in the upper and lower portions of the wire binding member 15 . respectively, and after processing to finish both ends of the first wire 11, by injecting epoxy into the through hole of the wire binding member 15, the area where the wires are bound is increased, and the first wire 11 ), and by further connecting the second wire 12 to both ends of the stably bound first wire 11, a reinforced concrete member around which the first wire and the second wire are surrounded. At 100, the wire may be overlapped in an X-shape.

At this time, when the epoxy is injected into the through hole of the wire binding member 15 through which both ends of the first wire pass, 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 reinforcement construction methods of a reinforced concrete structure 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 will be omitted. However, it will be understood by those skilled in the art that the configuration of the bolting fastening method described in detail below may be applied together to the configuration using the aforementioned wire.

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

4 to 6, the reinforced concrete member 100 has been described as an example of a rectangular reinforced concrete column. However, the reinforced concrete member 100 is not limited to a column, and may include all types of reinforced concrete members of various types such as reinforced concrete beams or slabs having various cross-sectional shapes such as circular.

As such, the anchor receiving part 101 for embedding and installing the anchor 110 may be formed on the outer surface of the reinforced concrete member 100 such as a column, beam or slab requiring repair and reinforcement according to the present invention. . The anchor receiving portion 101 is formed by digging a groove in the surface of the reinforced concrete member (100). And 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 constructed to fix a skin attachment to a concrete structure, and after drilling a hole in the concrete and installing the anchor, it can be fixed by combining the attachment to the part exposed to the outside of the concrete and fastening it with a nut. do.

The anchor of the present invention includes various types of anchors known in the prior art, for example, chemical anchors, set anchors, all anchors, wedge anchors, frame anchors ( frame anchors), sleeve anchors, strong anchors, dropin anchors, and the like.

In one 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.

More specifically, in an example of the present invention, two anchor receiving portions 101 on the left and right 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 depending on 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 units 101 may be sufficiently increased so that the reinforcement plate 200 attached to the reinforced concrete member 100 may be stably attached. For example, as in FIGS. 5 and 6 , it can be installed while increasing the number of anchor receiving units 101 in the vertical direction of the column on one surface of the reinforced concrete member 100 of a square column.

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

The conventional steel plate reinforcing method using epoxy has excellent reinforcing effect in that it uses a steel plate as a reinforcing material, but there is a problem in that the step for injecting the epoxy is complicated and the reinforcing effect is significantly lowered when the epoxy is not sufficiently injected. In addition, in the case of improving the thickness of the cross section of the reinforcing material to improve the reinforcing effect, since the thickness of the epoxy injection must be increased together to withstand the increased weight of the reinforcing material, it is essential to increase the amount of epoxy used and increase the thickness of the adhesive layer, not the reinforcing material. It was.

In addition, in the conventional reinforcement method using epoxy as an adhesive, since the epoxy needs to be injected between the structure and the reinforcing material, it was essential to prevent the epoxy from leaking. For example, the work process is difficult, such as putting a reinforcing plate on the entire slope of the column and sealing the perimeter of the reinforcing plate with a separate sealing operation, or welding between steel plates to prevent the epoxy from leaking while installing separate injection holes for epoxy injection. It was complex and required skillful skills.

However, in the present invention, since epoxy is not injected between the reinforced concrete structure and the reinforcing plate, it does not go through the edge sealing operation and welding process as in the prior art, so the difficulty of the operation is low, and even unskilled people can easily construct it. In addition, since the adhesive is not used, even when the thickness of the reinforcing material is to be increased, it is not necessary to consider the increase in the amount of the adhesive used.

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 on which the anchor 110 and the bolt 120 can work effectively. The anchor 110 is installed in the anchor receiving part 101 so that the bolt can be inserted into the anchor 110, a female thread corresponding to the screw thread of the bolt is formed. The size, length, thickness, etc. 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 reinforcement 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 embedding the anchor 110 in the anchor accommodating part 101 in order to increase the fixing force, adhesion, etc. of the anchor 110 to the reinforced concrete member 100, between the anchor accommodating part 101 and the anchor 110 An adhesive (eg, an epoxy adhesive) and a grouting material may be additionally injected.

For example, after forming the anchor accommodating part 101 , the anchor 110 may be installed after the adhesive is injected into the anchor accommodating part 101 , and the bolt 120 is fastened to the anchor receiving part 101 . After injecting an adhesive into the female threaded portion inside the anchor 110 before, the bolt 120 may be fastened. That is, the 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 passing 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, there is no need 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 the brittle fracture of the concrete structure occurs before the reinforcing material exhibits the reinforcing performance due to the peeling of the epoxy adhesive interfacial layer can be solved through the bolting compression method of the present invention.

However, in the case of using the bolt compression method as described above, the bolt must be firmly fixed to the structure without loosening. In particular, it prevents the anchor 110 embedded in the concrete structure 20 from departing from the anchor receiving part 101 even when vibrations including earthquakes occur and during expansion and contraction of concrete, and the reinforcement 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. Therefore, in the present invention, it is characterized in that the reinforcing structure includes a spring, which is an elastic structure, for such a function.

In addition, the reinforcing plate 200 may be a reinforcing plate 200 surrounding the entire perimeter of the cross-section of reinforced concrete, or may be a reinforcing plate 200 surrounding a portion of the perimeter of the cross-section of reinforced concrete. That is, the entire circumference of the cross-section of reinforced concrete may be reinforced with one reinforcing plate 200 , and the circumferential portion of the cross-section of reinforced concrete may be reinforced several times with several reinforcing plates 200 .

At this time, the first reinforcing 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. It may be formed in a “L” 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 continuous sides of the reinforced concrete member 100 may mean two consecutive sides among the four sides of the rectangle shown in FIG. 4, and the four corners where the reinforced concrete member 100 meets the floor and the ceiling and the 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 mean the remaining four surfaces except for the surface that meets the ceiling and the floor, when the rectangular-shaped reinforced concrete is taken as an example.

The first reinforcing plate 200 may be formed by bending one plate, but may be formed in a “L” shape by connecting two plates, and the second reinforcing plate 200 may also be formed by bending one plate. However, it is also possible to form a “b” shape by connecting two plates. The first reinforcing plate 200 and the second reinforcing plate 200 may be transported to the construction site in a state in which the 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 picture below is an example of connecting between the reinforcing plates 200 by the hinge connecting portion 204 , and showing the front and back sides of the reinforcing plate 200 connected by the hinge connecting portion 204 .

The hinge of the hinge connection part 204 may be selected from a generally known hinge, that is, any one or more of a stainless steel hinge, a stainless steel welding hinge, a stainless steel casting hinge, and a spring hinge. It will be readily understood by those skilled in the art that, in addition to the above-listed hinges, a generally used hinge may be used as the hinge connection unit 204 .

The hinge connection portion 204 may be formed in one portion of each bent portion of the first reinforcing plate 200 and the second reinforcing plate 200, or may be formed in the entirety of the bent portion, One or two or more hinged connections 204 may be installed.

When the reinforcement of the reinforced concrete member 100 is completed by forming the hinge connecting portion 204 in the bent portion of the first reinforcing plate 200 and the second reinforcing plate 200, the hinge connecting portion 204 may be located at the edge of the reinforced concrete member 100 .

At this time, the edge of the reinforced concrete member 100 means 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 perpendicular to the floor means

In the case of installing the reinforcing plate 200 at the construction site, taking the case where the reinforced concrete member 100 is a square reinforced concrete column as an example, a maximum of four reinforcing plates 200 are each constructed and four construction processes are to be performed. Although inconvenient, when constructing the first and second reinforcing plates in a state where they are connected by the hinge connection part 204, a large area of the reinforced concrete member 100 can be constructed at once, thereby shortening the construction time, Convenience of construction can be increased.

In addition, by using the reinforcement plate 200 formed of two plates integrally connected by the hinge connection part 204 in the bent part, the corner part can be continuously and completely reinforced, so that the continuity of the reinforced concrete member 100 The corners formed by the meeting of the sides to be formed can be reinforced without gaps.

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 corners in between are exposed without completion of reinforcement, and additional reinforcement is required. Accordingly, in one embodiment of the present invention, continuity is imparted to the reinforcing plate 200 by using the hinge connecting portion 204 to be reinforced up to the corner portion.

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

At this time, the coupling of the connection protrusion 2300 and the connection hole 2100 can be selected from any one of a coupling method such as a press-fit method or a force-fit method, and in addition to the above-described coupling method, the connection part is used as a fastener and a fastener to be fastened. It will be understood by those skilled in the art that various bonding methods for 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 fixed by fastening the bolt and the first nut, or may be installed and fastened later. may be

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

When the reinforcement of the reinforced concrete member 100 is completed by the coupling member 203 being formed and fastened between the reinforcing plates 200 , the coupling member 203 is the reinforced concrete member 100 of the It may be located at the edge. The coupling member 203 formed between the reinforcing plates 200 includes a coupling member 203 formed between the above-described first reinforcing plate 200 and the second reinforcing plate 200 and fastened thereto. .

The reinforcement method of the reinforced concrete structure using the reinforcement plate according to the embodiment described above is a reinforcement plate (ie, three bendings) in which the reinforcement plate 200 surrounds the entire circumference of the four side surfaces of the reinforced concrete member 100 . It may be a reinforcing plate 200 having a curved portion), and may be a reinforcing plate (ie, reinforcing plate 200 having two bent portions) that surrounds three side surfaces, and does not surround the two side surfaces. It may be a reinforcing plate (that is, the reinforcing plate 200 having one bent part), or it may be a reinforcing plate 200 having a shape corresponding to one side without a bent part, it is easy for a person skilled in the art to know. can be understood In this case, the bent portion may be formed as a hinge connecting portion 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 reinforcing plate and the second reinforcing plate) of the reinforced concrete member 100 Corners may be located. At this time, since the edge of the reinforced concrete member 100 is not reinforced by the reinforcing plate 200, the continuity of the reinforcement may be deteriorated. Therefore, according to an embodiment of the present invention, the reinforcing plate 200 is connected to each other by installing and fastening the coupling member 203 between the reinforcing plates 200 in order to reinforce up to the edge portion of the reinforced concrete member 100 . can connect

The effect of reinforcement is also maximized. can be

That is, the coupling member 203 applies a tension force between the reinforcing plates 200 and restrains the reinforced concrete member 100 of the reinforcing plate 200 by applying the tension between the reinforcing plates 200 . power may be greater. 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 an interference-fitting method, it is possible to effectively reinforce the reinforcing plate according to an embodiment of the present invention. 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 so that it can be folded and unfolded by being connected by a hinged hinge. At this time, a connection hole 2100 is formed in another portion 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 .

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

7 is a view exemplarily showing a configuration in which an elastic member is arranged at an anchor in a method of reinforcing a reinforced concrete structure using a reinforcing plate and a reinforcing structure according to a third embodiment of the present invention, and FIG. 8 is the present invention. In the reinforcement construction method and reinforcement structure of a reinforced concrete structure using a reinforcing plate according to the fourth embodiment of FIG. 9 is a view exemplarily showing a method in which a reinforcement method of a reinforced concrete structure using a reinforcement plate is applied 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 the embodiment, it is a view exemplarily showing a state in which the reinforcement construction method of the reinforced concrete structure using the reinforcement plate installed with the coupling member is applied to the structure.

7 to 10, the reinforced concrete member 100 has been described as an example of a rectangular reinforced concrete column. However, the reinforced concrete member 100 is not limited to a column, and may include all types of reinforced concrete members of various types such as reinforced concrete beams or slabs having various cross-sectional shapes such as circular.

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

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

Therefore, depending on the type of anchor used, a bolt 120 that is previously fastened to the anchor 110 like an anchor bolt may be used, and a separate bolt 120 that meets the standard of the anchor 110, for example, It will be understood by those skilled in the art that a computerized bolt may be used.

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

The first spring 140 is installed on the outer periphery of the bolt 120 in the upper portion of the anchor (110). The first spring 140 may be installed after embedding the anchor 110 or after fastening the bolt 120 to the anchor 110 . That is, the first spring 140 is first positioned on the reinforced concrete member 100 before the reinforcing plate 200 is fastened with the bolt 120 . Then, by fastening the reinforcing plate 200 , the first nut 130 is tightened so that the first spring 140 abuts against the reinforcing plate 200 .

The first spring 140 is located inside the reinforced concrete member 100 and applies the vibration applied to the reinforced concrete member 100 and the expansion and contraction force of the concrete to the reinforced concrete member 100 as a reinforcing material. (200) can be effectively transmitted. As such, the first spring 140 is in close contact with the reinforcing material inside the concrete, so that 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 of 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 continuously subjected to a force due to vibration, impact, expansion, contraction, etc. of the concrete, which causes the anchor 110 and the bolt 120 and A phenomenon in which the coupling 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 loosened or damaged by an external force such as vibration, and the reinforcing plate 200 is separated from the reinforced concrete member 100 .

In order to install the first spring 140 having this effect, after forming the anchor receiving part 101 on the outer surface of the reinforced concrete member 100, the first spring receiving part ( 102) may be further formed. At this time, the diameter (d _s1 ) of the first spring receiving portion 102 may be greater than or equal to _{the diameter (d a} ) of the anchor receiving portion 101 . Therefore, in one embodiment of the present invention, when the anchor receiving portion 101 is formed, the reinforced concrete member 100 by the sum of the embedding length (L) of the anchor 110 and the length (l) of the first spring 140 . Doedoe digging a groove from the outer surface, the diameter is formed to a size that can accommodate the anchor 110 (d _{a ), the diameter (d s1} ) of the first spring receiving portion 102 (d s1) of the anchor receiving portion (110) If it is to be formed larger than the diameter (d _a ), as much as 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 part 110 is formed, the first spring _{A groove equal to} the diameter (d s1 ) of the receiving portion 102 may be additionally formed.

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

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 unit 170 may be added to the first spring receiving unit 102 . The first spring protection unit 170 is to prevent foreign substances such as concrete fragments from being caught in the first spring 140 , and is a cylindrical member installed according to the diameter of the first spring receiving unit 102 , or in concrete. It may be a coating layer coated with a paint to be used.

The bolt 120 is installed through the inner diameter of the first spring 140, and then the through hole 210 of the reinforcing plate 200 is penetrated with the bolt 120 to attach 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 bolts corresponding to each.

The reinforcing plate 200 may be an iron plate or a steel plate used in a general steel plate reinforcement method. However, the present invention is not limited thereto, and a steel material 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 (eg, carbon fiber board, aramid fiber board, glass fiber board), etc. may include. In addition, the weight, size, thickness, etc. of the reinforcing material may be determined according to the degree of damage to the concrete structure and the degree of reinforcement therefor.

Therefore, the reinforcing plate 200 may be formed in one single layer or in one or more multi-layer 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 tightened.

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 flat washers, spring washers, rubber washers and the like may be used.

In general, in a fastening method using a bolt and a nut, the elasticity is lost due to the yielding phenomenon of the material, or a space is generated due to the vibration of the fastening structure and parts, and the friction force between the bolt and the nut is reduced and loosening may occur. In order to prevent an accident from occurring due to this loosening phenomenon, a method of fixing the bolt and the nut by injecting an adhesive is used in the prior art, but there is a problem that the nut must be destroyed when the nut must be dismantled for maintenance. .

7 relates to an embodiment in which the first spring 140 is added to the configuration described above with reference to FIGS. 4 to 6 , and a description of the configuration and method equally applied to FIGS. 4 to 6 will be omitted. Likewise, it will be understood that the manner in which the reinforcement methods and configurations of FIGS. 4 to 6 are applied to the concrete structure may be applied in a similar manner to the exploded perspective view of FIG. 9 for the configurations indicated by the same reference numerals in FIGS. 7 to 10 .

Reinforcement method and structure according to an embodiment of the present invention is to prevent the loosening phenomenon while convenient construction by additionally installing the second spring 150 and the second nut 160 on the first nut 130 characterized. The configuration of this 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 the reinforced concrete structure using the reinforcement plate of the present invention is a reinforced concrete member 100, a reinforcement plate 200, and an anchor 110 for fastening them, a bolt 120, the first nut 130 and the first spring 140, and the coupling member 203 connecting between the reinforcing plate 200 and the hinge connecting portion formed in the bent portion of the reinforcing plate 200 ( 204), and a second spring 150, a second nut 160, and a nut cap 300 may be included.

9 is an exploded perspective view illustrating an example of how the configuration of FIG. 8 is applied to a structure, the reinforced concrete member 100, the reinforcing plate 200 and the anchor 110 for fastening them, bolts ( 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, a second nut ( 160) and the reinforcing method of the embodiment including the nut cap 300 may be applied to a 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 same configuration is applied to FIGS. 7 and 8. and a description of the method and the like will be omitted. Likewise, it will be understood that the manner in which the reinforcement 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 for the configurations indicated by the same reference numerals in FIGS.

The first nut 130 is fastened to the bolt 120 , and the second spring 150 and the second nut 160 are sequentially positioned on the bolt 120 protruding above the first nut 130 . make 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 being bent or bent. serves as a guide.

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

In one example of the present invention, when the first nut 130 is rotated in the loosening direction, the second spring 150 having one end positioned in the first fixing groove 131 of the first nut 130 rotates in the opening direction. That is, it may be installed so that the second spring 150 is relaxed. Accordingly, one end that is in contact with the first nut 130 by the loosening energy acting in the direction in which the first nut 130 is unwound, that is, the lower end of the second spring 150, the direction in which the second spring 150 opens. 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 ), the second spring 150 is transmitted in the retracting direction to prevent loosening of the first nut 130 .

Accordingly, the second spring 150 presses the first nut 130 from the upper portion of the first nut 130 to prevent the first nut 130 from loosening due to vibration or the like. In addition, the second spring 150 absorbs vibration transmitted through the reinforcing plate 200 , the bolt 120 , and the nuts 130 and 160 to the elastic member and at the same time presses it from the top of the first nut 130 . When the first nut 130 is used alone, frictional force is increased to prevent rotation of the first nut 130 .

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

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

According to the reinforcing method and the reinforcing structure of the present invention, since welding and the use of adhesives are minimized, maintenance and repair of the reinforcing structure is easy even after reinforcing. That is, the reinforcing plate 200 is not welded or between the reinforcing plate 200 and the concrete member 100 is not bonded with epoxy. And the second spring (140, 150), the first and second nuts (130, 160), bolt 120, the reinforcing plate 200, etc. of the reinforcing structure, such as only some members of the problem occurred repair, replacement and maintenance Management costs can also be reduced.

In particular, bolts and nuts expand or contract not only by vibrations such as earthquakes, but also by changes in ambient temperature, so that the screw loosening phenomenon may occur. However, according to the reinforcing method and the reinforcing structure of the present invention, maintenance and repair are easy, so that the bolts and nuts can be re-tightened without disassembling the entire reinforcing structure.

It is not necessary to use an epoxy adhesive or face welding between the reinforcing plate 200 and the reinforcing plate 200 at the edge.

At this time, when the side surface of the rectangular reinforced concrete member 100 is reinforced when the reinforcement plate is reinforced by the above-described bolting method, four reinforcement plates corresponding to the side surface are reinforced, respectively, so that the side and side surfaces of the reinforced concrete member 100 are reinforced. The corners in between are exposed without completion of reinforcement, and additional reinforcement is required. That is, there may be a need to reinforce the perimeter of the reinforced concrete member 100 without gaps by continuously reinforcing the reinforcing plate 100 including the corner portion. Therefore, in one embodiment of the present invention, the reinforcing plate 200 is formed by using the reinforcing plate 200 in which the portion corresponding to the corner is bent so as to be reinforced up to the corner, and includes a hinge connection portion in the bent portion. It can be configured to have this continuity and be reinforced.

In addition, when installing the reinforcing plate 200 at the construction site, taking the case where the reinforced concrete member 100 is a rectangular reinforced concrete column as an example, a maximum of four reinforcing plates 200 are respectively constructed to perform four construction processes Although there is an inconvenience to go through, when the first reinforcing plate and the second reinforcing plate 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 one embodiment of the present invention, the edge portion can be continuously and completely reinforced by using the reinforcing plate 200 in which the hinge connection portion 204 is formed in the bent portion, so the continuous side surface of the reinforced concrete member 100 The edges formed by this meeting can be reinforced without gaps.

At this time, in the case of using a simply bent reinforcing plate, it may be inconvenient that the member occupies a large area of the construction site because it is formed in a L-shape, but the bent portion is formed by the hinge connection part 204, so it can be folded storage is possible. In addition, a pulling force is applied between the first and second reinforcing plates by the hinge connecting portion 204 formed in the bent portion, so that a tension force may be applied.

In the prior art, when it is necessary to attach a steel plate on each side like a concrete column, a method of separately welding between the steel plate and the steel plate at the edge of the column without bolting the column and the steel plate is used. Surface welding between the steel plate and the steel plate not only takes a considerable amount of time, but also has the disadvantage that the quality change of the welded part according to the skill of the worker is very large. In particular, in the case of steel plate reinforcement, high-strength CO ₂ welding is performed _{instead of general welding to improve reinforcing performance. This CO 2} gas welding has a constant welding rate and high tensile strength compared to arc welding, but requires skilled technology. The major disadvantage is that construction cost and time increase because of the requirement.

However, in the present invention, since the concrete column and the reinforcing plate are used in a bolting compression method, and two or more reinforcing plates are connected by a hinge connection part and the coupling member is installed, construction convenience is improved as well as work The range of quality fluctuations according to the skill level is also small, so you can expect a certain level of strength.

In the method of reinforcing a reinforced concrete structure using a wire and a reinforcement plate according to the above-described embodiment, the reinforcement plate 200 is a reinforcement plate (ie, three It may be a reinforcing plate 200 having two bent portions), and may be a reinforcing plate surrounding three side surfaces (ie, a reinforcing plate 200 having two bent portions), and may be a reinforcing plate 200 having two bent portions around the two side surfaces. It may be a reinforcing plate (ie, reinforcing plate 200 having one bent portion) that surrounds it, or it may be a reinforcing plate 200 having a shape corresponding to one side without a bent portion. can be easily understood by In this case, the bent portion may be formed as a hinge connecting portion 204 .
