Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a box-type reinforced concrete structure,

More particularly, the present invention relates to a bracket for reinforcing a right corner portion, more specifically, a pair of pressing plates vertically installed at the center of a base plate closely attached to a right corner portion by pressurizing and reinforcing both sides of a right side portion using a wedge- The present invention relates to a box-type reinforced concrete structure for reinforcing a box-shaped concrete structure in which the inner volume of a box-type concrete structure is relatively increased.

In general, boxed concrete structures used for underground cars, subways, waterways, etc., may have loads greater than the design load due to the traffic load acting on the upper part or the upper part. Due to such a load, the structural safety may be deteriorated due to excessive shearing force and excessive moment at the right corner, which is the corner portion between the vertical side wall and the ceiling and the side wall. Therefore, it is necessary to constructively reinforce the right-angled portion of the box-type concrete structure.

In the case of the box - type concrete structure, the concrete does not play a role of increasing the load - bearing capacity of the member, so there is a problem that it can not sufficiently resist the shearing force or the momentum. Therefore, it is necessary to disperse some of the shear force and the momentum acting on the right angles of the box - type concrete structure by supporting the shear force and part of the momentum of the right - angle concrete structure.

According to the above-mentioned necessity, a technique of reinforcing the strength of a structure by attaching an iron plate or a resin-impregnated reinforced fiberboard using an anchor to the inside of a box-shaped concrete structure has been proposed. However, as time passes, the strength of the steel plate or the fiber- There is a problem that reinforcement is not properly performed, and in the case of the reinforced fiberboard, there is also a problem of being eliminated due to corrosion.

In order to solve such a problem, Korean Patent No. 10-1338767 (a reinforcing device for the right corner of a box-type concrete structure) is proposed. The above-mentioned patent discloses a reinforcing structure for reinforcing the right-angled portion by dispersing and supporting a part of a momentum and a shearing force acting on a right-angled portion of a box-shaped concrete structure, and is installed in close contact with the right angled portion. A first member extending from one end of the main body, and a second member extending from the other end of the main body, wherein an angle between an imaginary straight line passing through the centers of the first member and the second member A reinforcing member configured to be larger than an angle formed between the ceiling portion and the wall portion of the box-like structure; A pressing means which is provided between the first member and the second member of the pressing means and presses the first member and the second member so as to be elastically deformed in a direction approaching each other; Fixing means for fixing the reinforcing member to the right corner portion; And adjusting means for adjusting the pressing force of the pressing means. The pressing means presses the right and left corners of the right angle portion in a direction away from each other. However, the reinforcing means is difficult to install and is installed apart from the right angle portion in the diagonal direction Therefore, there is a problem of reducing the internal volume of the box-type concrete structure.

Korean Patent No. 10-1709393 (a reinforcing device for a right angle portion of a box-shaped concrete structure) is proposed.

The structure for supporting the right-angled portion with the plate and the reinforcing effect are relatively poor.

Korean Patent Laid-Open No. 10-2017-0081140 (Seismic strengthening device for reducing shear force and moment generated in the right corner of a box-shaped structure) is proposed. The present invention relates to an apparatus for reinforcing seismic reinforcement which is installed at a right corner portion between a ceiling and a side wall of a box-like structure in an underground structure to reduce a shear force and a moment generated in a right corner portion, An anchor bolt coupled to the slots to fix the fixing plate to the ceiling and the side wall, and a pair of fastening protrusions formed on the other side of the fastening plate attached to the ceiling and formed with through-holes, A fixed government; And a connection hole formed at an upper portion of the fixing portion and connected to the fixing portion in a downward oblique direction, the connection hole being inserted between a pair of the fastening holes and being fastened by a connecting pin, ; A socket part connected to the other side of the fixing plate attached to the side wall in an obliquely upward direction and having an insertion hole at an upper portion thereof; And a rotating rod is disposed between the connecting portion and the socket portion so as to be fixed in an oblique direction, wherein the rotating rod has a screw thread formed on an outer circumferential surface of an upper end portion thereof so as to be rotatably coupled to the screw hole to adjust a degree of reinforcement, Wherein a lower end portion of the rotation bar is inserted into the insertion hole at a position where the tensile force acts on the seismic strengthening apparatus when the box-shaped structure is subjected to a seismic load, The shear force and the moment generated in the right corner portion can be reduced by making the reinforcing device resisting the compressive force in the right corner portion where the compressive force acts on the seismic strengthening device. , By pressing the opposite corners of the right-angled portion in a direction away from each other, However, since it is difficult to install and installed in a diagonal direction from the right corners, there is a problem that the internal volume of the box concrete structure is reduced.
