APPARATUS ENLARGING THE THICKNESS OF LOWER PART OF CONCRETE STRUCTURE

摘要

The present invention, while fixing a plurality of reinforcing material injection pipe 200 on the lower surface of the reinforcement target element 100 of the concrete structure, the reinforcement 311 to the anchor 330 fixed to the lower surface of the reinforcement target element 100 To form a reinforcing frame 310, cast concrete 320 to form a concrete reinforcement layer 300, and form an adhesive layer 340 by injecting a reinforcement 400 into the reinforcement injection pipe 200. It provides a lower surface symptom device of the concrete structure, characterized in that configured to. The present invention does not need to control the vehicle while repairing or reinforcing work, and can prevent the separation of new and old concrete caused by dry shrinkage or creep after the concrete is placed. It can also be used to increase the ductility of concrete. In addition, the composite structure of the slab and the mold can be repaired, and the rigidity of the mold can be enhanced by increasing the secondary moment of the cross section of the mold. Since reinforced concrete is used as a structure, it is advantageous in long-term behavior and has an excellent reinforcing effect.
