PROBLEM TO BE SOLVED: To solve the problem wherein in curing (protecting) an opening frame or column, it has been necessary heretofore to correspond to the width of a protected surface of a structure, and the curing material itself should be worked to have clamping force so as to be fitted independently without a tape, so the flexibility and strength good for complicated machining are demanded toward the raw material of the curing material so that the use of petrochemicals is not avoidable. SOLUTION: In order to solve the problem, two protective materials 2a, 2b are slid corresponding to the width of the structure of the column and the opening frame and used, whereby the structure can be fitted and protected only with the clamping force of a joint material 4, not with the end parts of the protective material. The above structure enables raw material hard to be machined complicatedly such as paper to be formed. It can cope with the case where the protected surface of the structure has different lateral width, projecting and recessed parts of the curing material can be eliminated, and the use for an opening frame in a narrow place is possible.
