REPAIR METHOD OF CRACKING ON EXTRUSION MOLDING PLATE, AND REPAIR STRUCTURE BODY

摘要

PROBLEM TO BE SOLVED: To provide a repair method of cracking and a repair structure body, capable of reinforcing a surface plate on a rear side and capable of sufficiently ensuring a bending performance and a shear performance required for a panel, relating to an extrusion molding plate in horizontal stacking in which cracking occurs along width direction.SOLUTION: An extrusion molding plate includes a pair of almost rectangular surface plates arranged almost parallel to each other, a plurality of barrier wall parts which extend in length direction of the surface plate to connect the pair of surface plates as one body with a predetermined interval, and a hollow part formed between the adjoining barrier wall parts. It is attached to a body of a building so that the length direction is almost horizontal. In a repair method of cracking that occurs in width direction of it, a hole is opened near the cracking of the surface plate, and mortar is injected/packed into the hollow part through the hole for solidifying. Thus, so as to stride the cracking, a mortar fitting part which is dense and pillar-like is formed at the hollow part.SELECTED DRAWING: Figure 2
