Being the formation board for additional strength in order

摘要

PROBLEM TO BE SOLVED: To prevent adhesion of fat and oil, dust, and the like during transportation or the like by covering a joint part of molded plates formed of fiber reinforced resin compound material for reinforcing an existing concrete structure, with a mold release protective sheet. ;SOLUTION: At the time of reinforcing an exposed part of a column, a beam, or the like of reinforced concrete construction, reinforcing molded plates divided in two or more parts formed of cold setting epoxy resin or the like reinforced by carbon fiber or the like are combined and brought into close contact with a part to be reinforced. A joint part of the reinforcing molded plates is covered with a mold release protective sheet formed of mold release paper, or synthetic resin fiber woven fabric or knitted fabric so as to prevent fat and oil, dust, and the like from sticking to the joint part during transportation and handling at a construction site. The protective sheet is peeled immediately before jointing the reinforcing molded plates, and a crimp face or a crepe face is formed on the surface after peeling so as to be able to display anchor effect to the adhesive. The molded plates easy to handle and excellent in adhesive property can therefore be obtained.;COPYRIGHT: (C)1999,JPO
