As shown in FIG. 7, the panel 60 has a fitting groove 62 at one end and a protrusion 63 at the other end. The concrete structure 30 has various shapes and sizes, The panel 60 is extended and fixed by sandwiching the fitting groove 62 and the protrusion 63 according to the area of the concrete structure 30 so that the panel 60 can be fixed using the fixing member 50 So that it can be combined.

The panel 60 can be easily worked regardless of the size of the concrete structure 30 due to the configuration of the fitting groove 62 and the protrusion 63. [

An injection groove 64 is formed in upper and lower portions of the panel 60 so as to inject the mortar filler m in a state of being coupled to the side surface of the concrete structure 30, And an engaging groove 65 for engaging with the anchor or the concrete structure 30 is formed and coupled using the fixing member 50. [

A separate injection pin 66 is coupled to the injection groove 64 of the panel 60 to secure a fixing force when the mortar filler m is injected. The cap 67 is fitted to the injection pin 66 so as not to be discharged to the outside.

The panel 60 of the present invention constructed as described above can be used individually on the side surface of the concrete structure 30 as a panel for reinforcing concrete structure, or can be used together with the anchor.

8 to 16, a concrete structure repair and strengthening method using an anchor for a concrete structure repairing reinforcement and a panel as described above will be described.

The method includes the steps of: wrapping an outer surface of a concrete structure using a plurality of directly formed meshes and fixing the outer surface of the concrete structure; connecting the mesh and the connection reinforcing plate to each other after constructing a connecting reinforcing plate at the corner portion of the concrete structure, And a mortar filling material is inserted into the space between the mesh and the concrete structure. The method of the present invention is characterized in that the fixing step comprises using the anchor, A plurality of fixing grooves 31 protruding inward from the surface are formed after the fixing member 50 is formed and the anchors of the fixing grooves 31 are inserted to fix the fixing members 12 by fixing the fixing members 50 ) With the anchor.

In more detail, as shown in FIG. 8, the surface of the concrete structure 30 to be reinforced and reinforced is chipped to form the concave and convex portions 32.

Thereafter, as shown in FIG. 9, a plurality of fixing grooves 31 are formed on the surface of the concrete structure 30. In forming the fixing grooves 31, The fixing groove 31 is formed by using a drill which protrudes to the inside of the fixing groove 31 naturally. A plurality of the fixing grooves 31 are formed and then the body 10 of the anchor is inserted so that the engaging pieces 12 are engaged with protruding portions formed on the inner side of the fixing groove 31, (Not shown).

As shown in FIG. 10, after an anchor is formed, a plurality of bars 40 are seated by placing a mesh formed of a plurality of bars 40 thereon.

Although not shown in the drawing, the bar 40 is wrapped around the side surface of the concrete structure 30, and a separate reinforcing plate is formed at the corner of the concrete structure 30 to be connected to the mesh composed of the bar 40 So that a separate description will be omitted, and the fixing member 50 can be used in combination with the anchor.

After using the anchor alone, a separate mortar filler m is injected into the gap formed between the concrete structure 30 and the anchor and the bar 40 to widen the space.

Meanwhile, the durability of the concrete structure 30 can be improved by constructing the panel 60 together with the anchors. In this case, as shown in FIG. 12, a mesh composed of the bar 40 is formed on the anchor, The panel 60 is mounted on the upper portion of the bar 40 without being joined by the member 50 and then the connection groove 22 formed on the upper portion of the throttle portion 20 of the anchor as shown in FIG. The clamping groove 65 of the panel 60 is positioned on the same line and then the panel 60 and the tightening portion 20 are joined together by the fixing member 50 to be integrally formed.

14 to 15, the mortar filler m is injected through the injection hole 64 of the panel 60. The injection hole 66 is coupled to the injection hole 64 The mortar filler m is injected by inserting the mortar injector 70 into the space between the panels 60 and the fixing grooves 31 into which the anchor is inserted, (67).

At this time, when the mortar filler (m) is injected, it is injected sequentially from the lower part to the upper part. Normally, it must be filled from the bottom by gravity, but air or water may be discharged to the outside.

16, a plurality of anchors are inserted and fixed to a plurality of fixing grooves 31 formed on the surface of the concrete structure 30, that is, the outer peripheries of the concrete structures 30, The concrete structure 30 is completely fixed by injecting the mortar filler m after the reinforcing member 40 and the panel 60 are sequentially stacked and fixed using the fixing member 50. The concrete structure 30 can be used for a long time by a single repair So that the economic efficiency can be improved.

3 is used as the surface of the concrete structure 30, the mesh formed of the bar 40 may be stacked and then the bar 40 may be inserted into the fitting portion 24, The panel 60 can be fixedly coupled to the panel 24 by applying the same method after lamination.

That is, depending on the type of the anchor inserted into the fixing groove 31 of the first concrete structure 30, the mesh is stacked or meshed and fixed.

According to the concrete structure repairing and reinforcing method of the present invention, a plurality of bars (40) are formed by fixing a plurality of the anchors in the fixing grooves (31) of the surface of the concrete structure (30) The panel 60 and the anchor are successively joined to each other with the fixing member 50 by providing a separate panel 60 so that the concrete structure 30 to be repaired and reinforced can secure a more firm fixing force The mortar filling material m is injected into the injection grooves 64 of the panel 60 so as to increase the space therebetween, and thus it can be used for a long time through a single repair, thereby improving the economic efficiency, It is a useful invention to which convenience is given.
