EXPANSION JOINT CONSTRUCTION METHOD OF BRIDGE OR CONCRETE STRUCTURE USING ELASTIC SEAL MATERIAL AND CARBON FIBER

摘要

The present invention is a construction method of placing a stretch joint on the upper surface of a bridge or structure spaced apart at a predetermined gap, the first step of cleaning the upper surface and applying a primer; A second step of sequentially installing a first perforated pipe and a backup material in the gap; To the upper portion of the gap and to the cut portion of the bridge or the structure, coating an elastic sealing material and sequentially installing a rubber support plate and a carbon fiber pad, or sequentially installing a rubber supporting plate and a carbon fiber pad and coating the elastic sealing material. The third step comprising; And after the completion of the third step, characterized in that it comprises a fourth step of performing a finishing coating between the cut portion and the adjacent upper surface, to increase the structural strength of the structure to increase durability and increase the tensile strength to reflect It relates to the expansion joint of a bridge or a structure using an elastic sealing material and carbon fiber and to a construction method using the same, as well as to suppress cracks and ultimately to prevent the occurrence of portholes.
