Abstract: PROBLEM TO BE SOLVED: To easily, accurately and reliably hold a butting plate by forming installing parts for arranging a fire resistant material in a butting plate body, and forming projecting pieces on both sides of a body surface and a support part for vertically sliding a support arm hookingly fastened to a form holding separator on the reverse. SOLUTION: Holding pieces of installing parts 2, 3 are formed in a width or less of a fire resistant material in the almost center of a surface of a butting plate body 1, and projections are formed inside the holding pieces to prevent slipping-out of the fire resistant material inserted between the respective holding pieces. Next, projecting pieces 10, 11 are arranged on both sides of a surface of the body 1 to be inserted into a notch groove arranged in an earthquake resistant slit material to be made hard to slip out. A pair of support parts 14, 15 for freely sliding a support arm hookingly fastened to a form holding separator are formed on the reverse of the body 1. Efficiency of installing work of the erathquake resistant slit material and the fire resistant material to a butting plate is improved, and accuracy is improved.  Thus, when placing concrete after installing a form, the earthquake resistant slit material enduring even lateral pressure of the concrete can be arranged in a prescribed position of a concrete wall.
