Abstract: Disclosed are a panel for repairing and reinforcing a concrete body, a multi-purpose anchor, an anchor for level adjustment and injection a method for repairing and reinforcing the concrete body using the same, which can connect adhesives and anchors at weak parts of the concrete body, which is neutralized, aged, deteriorated, cracked due to water leakage, or segregated, or at parts requiring the repair and reinforcement due to a change in use environment. The composite reinforced panel includes lightweight concrete, high strength concrete or a steel plate and reinforcing means, thereby being effectively prevented from bad environments causing a drop of reinforcing capacity, providing good heatproof and fireproof properties, and maximizing merits of materials used as the reinforcing means.
