Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete reinforcing concrete structure,

This embodiment relates to a concrete structure reinforcing apparatus and a method for reinforcing concrete structures using the same. In other words, by binding concrete members such as pillars and beams of concrete structures in the circumferential direction, it is possible to prevent the concrete structure from being damaged by suppressing flexural deformation and shear deformation caused by external forces such as earthquake, and to improve the structural stability of the aged concrete structure And more particularly, to a method of reinforcing a concrete structure and a method of reinforcing a concrete structure using the same.

In the case of a concrete member such as a column of a concrete structure, it should be able to withstand not only the load of the upper structure but also an external force such as an impact applied from the outside or an earthquake. In particular, as a method of reinforcing a concrete member in order to prevent the concrete structure from being aged or to prepare for an earthquake after the concrete structure is applied, a method of reinforcing the outer periphery of the concrete member by reinforcing the reinforced concrete, fiber or steel plate is generally used.

However, reinforcing the concrete members with reinforced concrete increases the weight, requires a long period of time and costs, and complicates construction. Further, in the case of reinforcing with fiber, it is impossible to increase the rigidity of the concrete member. In the case of reinforcing with the steel plate, it is not easy to join the steel plate with the existing concrete member. Depending on the size of the steel plate, additional equipment may be needed to install the steel plate.

Therefore, in order to solve the problem of the above reinforcing methods, "Concrete Structure Reinforcement Method" of Korean Patent No. 10-1506110 and "Concrete Structure Reinforcement Apparatus and Method of Reinforcing It" of Korean Patent Publication No. 10-2015-0081408 are disclosed .

In the concrete structure, a steel connecting portion is disposed at each corner of the concrete structure, and a steel material to be coupled to the steel connecting portion is provided between the steel connecting portions. The steel connecting portion is orthogonal to the concrete structure through a tensile force applied to the steel, And a reinforcing device or reinforcement method for reinforcing concrete structures by applying a binding force acting in the direction of the center of the cross section.

However, the above-mentioned prior arts have a problem that they are not applicable or are difficult to apply when the concrete structure is not rectangular, that is, when the corner is not formed at a right angle due to a construction error or the like even if it is a cylinder or a square.

In addition, when the side surface of the concrete structure is not flat, the steel material is bent and a bending stress is generated to lower the tensile strength of the steel material, and it is not easy to fasten the steel material to the steel material connecting portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the structure of a concrete structure reinforcing apparatus according to an example of the present invention will be described in detail with reference to the drawings.

1A through 1F, an apparatus for reinforcing a concrete structure according to an exemplary embodiment of the present invention includes a plurality of tension members 20 disposed on the outer periphery of a concrete column 10, for example, a concrete column, And a plurality of connecting members 30 connecting the first and second connecting members 20 to each other. For convenience of explanation, the concrete member 10 is assumed to be a concrete column. The vertical direction refers to the axial direction of the concrete member 10, and the horizontal direction refers to the direction perpendicular to the axial direction.

The plurality of tension members 20 and the plurality of connecting members 30 are connected to each other to form an annular shape surrounding the outer periphery of the concrete member 10 to bind the concrete member 10 in the horizontal direction, The durability of the concrete member 10 can be increased with respect to the vertical load, the seismic load, etc. acting on the concrete member 10, and the safety can be ensured. That is, the durability and stability of the concrete member 10 are improved by suppressing the phenomenon that the side surface of the concrete member 10 is inflated by the axial load or the horizontal load acting on the concrete member 10.

Referring to FIG. 1C, the connecting member 30 is disposed at a corner of the concrete member 10, for example, at portions where the tension members 20 are interconnected to connect the tension members 20 to each other.

The connecting member 30 may be formed in a lance shape as shown in the drawing, a curved line (see Figs. 3 and 5), or a straight line. The connecting member 30 may include a tension member connecting portion 31 to which the ends of the tension member 20 are connected on both sides, that is, a portion to which the tension member 20 is connected.

The tension member connecting portion 31 may be formed with a tension member connecting portion 31 having the same shape or a tension member connecting portion 31 having a different shape on both sides of the connecting member 30. In other words, in the case of FIGS. 1C and 1E, the tension member connecting portions 31 on both sides of the connecting member 30 are formed in the same shape, but they can be formed on both sides differently. However, in the case where both sides are formed in the same manner, the portion where the nut is fastened is concentrated in one place, so that the installation efficiency of the concrete structure reinforcing apparatus can be increased.

The tension member connecting portion 31 may be simply formed with a screw hole in the connecting member 30 (see Fig. 3C). In this case, the screw formed in the tension member 20 can be connected to the tension member connecting portion 31, that is, the screw hole, thereby connecting the tension member 20.

The tension members 20 are coupled to the connecting members 30 installed on both sides of the tension members 20 and are tightened to thereby bind the concrete members 10 in the horizontal direction to reinforce the concrete members 10.

The tension member 20 is generally elongated and may be formed in a straight line, a curved line (see FIGS. 3 and 5), or a bent line shape depending on the cross-sectional shape of the concrete member 10. The L-shaped configuration can be applied in the case of a quadrangular column in which a part of the connecting member 30 is omitted and the L-shaped tension member 20 is installed.

At the end of the tension member 20, there may be provided a fastening means 21 to be fastened to the tension member connection portion 31. The fastening means 21 comprises a fastening means 23 coupled to an end of the tension member 20 and a fastening means 23 provided on the inside of the fastening means 23, And may include rotating means 25.

Only one of the fixing means 23 and the rotating means 25 may be provided. That is, the tension member 20 can be coupled to the connecting member 30 with only one fixing means 23, or the tension member 20 can be coupled to the connecting member 30 with only one rotating means 25 . In this case, the rotating means 25 serves as a fixing means.

In the case where the rotating means 25 and the fixing means 23 are provided together, the two constitutions may be provided on the tension member 20 after they are separated from each other or welded to each other to be installed together with the tension member 20, Or may be integrally fabricated and installed in the tension member 20.

The securing means 23 allow the tensioning element 20 to be secured to the tensioning element connection 31 so that the tensioning element 20 can remain tensioned. The cross section of the fixing means 23 may be formed in a rectangular, hexagonal, octagonal or the like. The fastening means 23 may also be a separate member or nut and may be screwed to the end of the tension member 20 or welded to the tension member 20 or integrally fabricated with the tension member 20 . That is, a bolt head or the like is formed on one side of the straining member 20, that is, a fixing means 23 integrally formed with the straining member 20, and the other side can be fastened to the straining member 20 like a nut .

The rotating means 25 is provided on the inner side of the fixing means 23, that is, on the side of the fixing means 23 in the direction toward the center of the tension member 20 and supported by the fixing means 23, As shown in FIG. That is to say that the rotating means 25 can be supported by the fastening means 23 coupled to the tensioning element 20 without being coupled to the tensioning element 20 itself or to the tensioning element 20 itself .

The tension member 20 can be freely rotated by means of the rotating means 25 so as to be rotatable with respect to the tension member connection portion 31. [ The side face of the concrete member 10 is horizontally protruded or the angle of the corner of the concrete member 10 is not exactly right or the side face of the concrete member 10 is not an exact arc as designed The tensile member 20 is not warped unexpectedly or a bending stress is not generated in the tensile member 20 and an unexpected bending stress may not be generated in the connecting member 30. [

The rotating means 25 may be formed in the center hole to allow the tension member 20 to be pierced, i.e. to simply insert the tension member 20, or it may be manufactured integrally with the tension member 20, (20), or may be screwed to the tension member (20) after a hole is formed through the center and a screw is formed inside the hole.

The inner surface of the rotating means 25 may have a spherical shape so that the tension member 20 can be easily rotated with respect to the tension member connecting portion 31. In this case, the tension member connection portion 31 of the coupling member 30 is provided with a passage groove 33 through which the tension member 20 passes, a rotary groove 34 into which the rotary means 25 is inserted, And a fixing groove 37 into which the base plate 23 is inserted.

The rotating means 25 may be a hemispherical shape having a hole formed at the center thereof, or a nut-like shape may be combined with the hemispherical outer surface.

The passage 33 may be a circular hole through which the tension member 20 passes or may be a square shape with various shapes, for example one side open, through which the other tension member 20 can pass.

It is preferable that the rotary groove 25 is formed to have a spherical shape corresponding to the spherical surface of the rotary means 25 so that the rotary means 25 is smoothly rotated.

The fixing groove 37 is formed by forming a fixing jaw such that the fixing groove 23 is spaced from the fixing means 23, that is, a rectangular, hexagonal, or octagonal shape, . The fixing jaw may be formed only on the outer side of the rotation groove 34, that is, on a part of the opposite side of the central portion of the tension member 20 (see FIG. 1C), or the fixing jaw may be formed only to the extent that the fixing means 23 does not rotate (See Fig. 1D), or between the rotation grooves 34 on both sides. It is preferable that the inner surface of the fixing means 23 (the side surface on the side of the central portion of the tension member) is spaced apart from the inner surface of the fixing groove 37 by a predetermined distance to prevent the tension member 20 from rotating.

Referring to FIG. 1E, the fastening means 21 can be constituted by only the rotating means 25 without the fixing means 23. FIG. The rotating means 25 may be constituted by a cylindrical rotary shaft 28 coupled to the end of the tension member 20 at right angles. In this case, the tension member connection portion 31 of the coupling member 30 includes a passage 33 through which the tension member 20 passes, and a rotary shaft groove 38 through which the rotary shaft 28 can be inserted . The rotary shaft 28 and the rotary shaft groove 38 are formed in a vertical direction and the tension member 20 can rotate about the rotary shaft 28. In addition, the passage 33 through which the tension member 20 passes requires a certain amount of clearance in the horizontal direction so that the tension member 20 can rotate.

The rotating shaft 28 can have a rotating function and a fixing function together with the tension member 20 with a very simple structure.

1f, it further comprises a support member 60 provided in the middle of the tension member 20 to support the tension member 20 at the side of the concrete member 10, and the support member 60 May be formed with a recessed portion 62 into which the tension member 20 is inserted in the longitudinal direction.

That is, since the tension member 20 is installed at a predetermined distance from the side surface of the concrete member 10 by the connecting member 30, the tension member 20 is balanced so as to support the concrete member 10 in a large area, The concrete member 10 can be firmly supported. Further, the shape of the support member 60 is not limited to the shape shown in Fig. 1F, and a straight line, a curved line, or the like is also possible. That is, the support member 60 may be installed on a flat surface or a curved surface of the concrete member 10.

In addition, the support member 60 may be formed with a through-hole 64 through which the tension member 20 passes in the longitudinal direction (see FIG. 3D).

2A to 2C, the rotating means 25 may include a rotating arm 26 protruding in both lateral directions, that is, the axial direction (vertical direction) of the concrete member 10. At the same time, the connecting member 30 may be formed with a passage 33 through which the tension member 20 passes and a rotary cutout groove 36. [ The rotary arm 26 may be inserted into the rotary cutout groove 36 and rotatably engaged.

That is, the rotating means 25 has a rotating plate protruding from both sides (upper and lower sides) of a hexahedron (see Fig. 2C) and a sphere, and a hole through which the tension member 20 is inserted, As shown in FIG.

It is preferable that the rotating means 25 is provided so as to be spaced apart from the side of the concrete member 10 or the connecting member 30 by a predetermined distance in the direction in which the rotating arm 26 is not formed.

The rotation means 25 is made of a separate component and is inserted into the tension member 20, so that the tension member 20 can be rotated.

It is preferable that the rotary cutout groove 36 is formed in a lance shape as shown in the figure to prevent the rotation arm 26 from coming off. Also in this case, the fixing groove 37 can be formed in a shape that prevents the fixing means 23 from rotating. Although not shown in the drawing, one fixing means 23 is integrally formed with the tension member 20 such as a bolt head, and a fixing groove (not shown) is formed on the coupling member 30 so as to prevent the bolt head from rotating It can be formed step by step.

It is also preferable that the open portion of the rotary cutout groove 36 is formed to be in contact with the concrete member 10 so that deformation of the coupling member 30 is prevented when the tension member 20 is tensed.

Referring to FIGS. 3A to 3D, the above-described embodiments can be applied to a case where the concrete member 10 has a circular cross section, that is, a cylindrical shape. All of the connecting members 30 may be made the same, but as shown in the drawing, a part of the connecting members 30 may be simply formed with screw holes on both sides, and a screw is formed at the end of the straining member 20 . Therefore, after the connection member 30 is fastened to the screw hole, the rotation means 25 is inserted from the coupling member 30 on the other side, and the nut as the fastening means 23 can be fastened. The outer side surface of the other side connecting member 30, that is, the outer side surface of the concrete member 10, is preferably opened for fastening a nut or the like.

The rotary cutout groove 36 may be formed in a linear shape or a cross shape. The angular shape can be prevented from being released after the rotation plate is inserted. When the tension member 20 is tensed, the inner side surface of the connecting member 30 is supported on the outer surface of the concrete member 10 so that the connection member 30 30 are prevented from being deformed and thus the resistance against deformation is increased as compared with the case where the cutting groove is formed on the outer surface of the connecting member 30. [

A plurality of concrete structure reinforcing devices composed of the plurality of tension members 20 and the plurality of connecting members 30 are installed in the concrete member 30 in the longitudinal direction and then the concrete member 30 is entirely covered, (Not shown). Such a finishing plate is formed of a flat plate, a square plate, a semicircular plate or the like in accordance with the shape of the concrete member 30 to cover the concrete member 30 to improve the appearance.

The finishing plate may be coupled to the concrete member 30, the tension member 20, or the connecting member 30. That is, it may be directly coupled to a hole formed in the concrete member 30 with a bolt or the like, or may be formed over the tension member 20 by forming a ring, or may be coupled to the coupling member 30 in a further configuration.

The rotation connecting portion 40 can adjust the coupling angle of the first connecting member 41 and the second connecting member 43 so that the concrete member 10 has various shapes such as circular, Thereby making it possible to apply a structure reinforcement device. In addition, the present invention can be applied to a case where the cross section of the concrete member 10 is inconsistent with the originally planned cross section, that is, the cross section is not exactly square or is not exactly circular. At the same time, the present invention can be applied to a case where a protrusion is present on the cross section of the concrete member 10. Therefore, unexpected stresses, particularly bending stresses, are not generated in the tension member 20 and the connecting member 30, so that there is no strength loss of the concrete structure reinforcing apparatus. In addition, even if the connecting member 30, that is, the connecting member 30 provided in the case of a cylinder or the like, is cylindrical, it can be bent by the hinge, so that the tension member 20 can be easily inserted.

4C, the rotation connection part 40 includes a pair of hinge holes 44 provided in the first connection member 41, that is, a pair of hinge holes 44 formed in the vertical direction, And a pair of hinge shafts 45 provided in the hinge holes 43 and inserted into the pair of hinge holes 44 and rotated. That is, a pair of hinge holes 44 formed at the center of a pair of rings coupled to the first linking member 41, a pair of hinges 44 projecting from a pair of circular plates coupled to the second linking member 43, And the shaft 45 is inserted in the space between the pair of rings and the pair of circular plates so that the hinge shaft 45 is inserted in the hinge hole 44, .

Therefore, the rotation connection portion 40 of the present embodiment is constituted by a pair of rings and a pair of circular plates, that is, the ring and the surface of the circular plate are rotated while contacting with each other, so that the rigidity of the rotation connection portion 40 is sufficient, Can be stably rotated.

The insertion member 50 may further be provided in a space between the pair of hinge holes 44 after the pair of hinge shafts 45 are inserted. The insertion member 50 prevents the hinge shaft 45 from being detached from the hinge hole 44, thereby preventing the rotation connection portion 40 from being separated in any case, thereby maintaining a stable connection state. The insertion member 50 can insert a member such as rubber, which is somewhat hard, in a forced fit manner, or insert a member such as a plastic or steel member. Further, after insertion of the insertion member 50, it may be bonded or welded with an adhesive to prevent the insertion member 50 from coming off.
