Description

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

More particularly, the present invention relates to a structure and method of reinforced concrete-reinforced concrete seismic reinforcement which is implemented to be directly fastened to concrete beams or concrete walls (concrete horizontal members and vertical members).

Generally, RC structures with almost middle and lower stories are reinforced by securing the necessary bearing capacity (stiffness) of the building by using steel brace, steel frame, brace damper, RC wall, etc. for the seismic reinforcement .

In comparison with the seismic performance (stiffness) of these reinforcement methods, the RC wall is the most rigid and the superior in performance because of the steel frame> steel frame brace> steel frame frame. Therefore, even if the construction site and area are smaller than other methods, Performance can be offset.

In the case of Korea, in order to strengthen seismic reinforcement in Korea, it was mainly applied to attach the inner elastic body to the outer surface of the opening where stress is concentrated. However, in order to secure the bonding and integration behavior with existing buildings over time, The method of construction was generalized.

However, there is a disadvantage in that it is necessary to dismantle all existing windows and finishing materials in order to construct the inside of the opening surface. Further, there is a problem in that unnecessary expense is incurred because the new window and the finishing material are always installed when the earthquake-proofing is reinforced.

In addition, there is a disadvantage that the construction period is lengthened due to the inevitable demolition and rework of the window and the finishing material, and the additional cost is incurred, thereby limiting the use of the existing building during the construction period.

Korean Patent No. 10-1532690 (Jun. 26, 2015) discloses a method for constructing a PC wall so as to form a protrusion on a concrete surface without bending the hoop frame Cast precast concrete wall and an earthquake-proofing method using the same, in order to conveniently and quickly curing the concrete installation curing in the field, and a seismic strengthening method using the pre-cast concrete wall, The present invention relates to a precast concrete wall installed in a wall of a building, A protrusion protruding from the one side surface of the panel part so as to form a step with the panel part; A plurality of first perpendicular rods arranged vertically in the panel section at regular intervals; A plurality of second right-hand roots arranged vertically at predetermined intervals in the protrusions, protruding from upper and lower ends of the protrusions, and extending and maintaining a gap with the surface of the panel; The first and second vertical frames are formed in the panel unit and the protruding unit, and are horizontally arranged at predetermined intervals to form a "C" shape, and one end thereof protrudes from the side surface of the protrusion, A plurality of first horizontal strip rods maintaining spacing from the surface of the panel portion; And a plurality of horizontal portions arranged horizontally and horizontally arranged in the panel portion so as to have an overall shape of "C ", and having one end thereof protruding from the surface of the panel portion of the region where the protrusions are not formed after passing around the first & A second horizontal stripe muscle; And the second horizontal strip projected to the surface of the panel portion after the panel portion is installed in the area where the mother wall is removed is bended in the form of a " C "like a whole of the first horizontal strip rope . According to the described technique, a PC wall is formed so that a protruding portion of a certain area is formed on the concrete surface in a state where the hoop frame (horizontal strip rope) at the joint portion with the existing building is not partially bending, Curing can be carried out conveniently and promptly, and it is possible to minimize the cost of demolition by removing only a part of the non-proof wall (masonry wall) to be installed or a construction site such as the inside of the wall, thereby avoiding demolition of existing windows and finishes It is possible to reduce the construction cost which was required for the construction of the window and the finishing material during the earthquake-proof reinforcement.

Korean Patent No. 10-1106712 (Oct. 10, 2012) discloses that a reinforcing member is integrally formed at the center of the top surface of a precast box beam in which a bending moment is intensively applied so that the center portion moment of the precast box beam, A rigid reinforcing structure and a rigid reinforcing method of precast concrete box beams for preventing cracking and preventing the generation of cracks while securing an open space on both sides of the precast box beam to increase the easiness of internal work, . According to the disclosed technology, a precast concrete box beam having an upper portion opened and a center portion of the precast concrete box beam are provided at the upper center of the beam to reinforce the center rigidity of the precast concrete box beam, Wherein the reinforcing member is inserted and fixed in an insertion groove formed in an upper portion of an inner wall of the precast concrete box beam, the reinforcing member and the precast concrete box beam are fixed by a fixing member, Wherein the fixing member is made of a steel wire or a steel bar and includes a supporting member for penetrating the reinforcing member through the precast concrete box beam and for supporting the reinforcing member between the reinforcing member and the precast concrete box beam, The member is the inner wall of the precast concrete box beam The reinforcing member is disposed on the upper surface of the reinforcing member, and the reinforcement member is supported on the upper surface of the reinforcing member, and a fixing member is fixed to the outer surface of the precast concrete box beam where the end of the fixing member is positioned, And a groove is formed.

The conventional concrete reinforcing structure as described above has a problem that it is difficult for the concrete beam or the concrete wall and the steel structure to be firmly fastened, so that the steel structure can be easily separated from the concrete beam or the concrete wall.
