Zusammenfassung:To solve the problem in which as conventionally a fire resistance efficiency material used to use a laminate lumber for finishing a main structure of a steel bar structure or a wooden structure and to have a fire resistance efficiency has not been standardized, there has been a restriction of a burden in an aspect of cost or trouble to finish the main structure of the structure in a steel bar structure or a wooden structure with the laminate lumber and to have a fire resistance efficiency.SOLUTION: In the invention, when a laminate lumber is used as a fire resistance efficiency material, a combination of a laminate lumber part to be a burning marginal part and a noncombustible material to be a stop burning part is a plate material, in addition this fire resistance efficiency is standardized by a regulation of Building Standard Act, a reduction of burden in terms of cost or trouble when the laminate lumber is used for finishing the fire resistance efficiency material of the main structure of the steel bar structure or the wooden structure and an active use of wooden material to have fire resistance efficiency are possible.SELECTED DRAWING: Figure 2 【課題】 従来、鉄骨造・木造の建物の主要構造部の仕上に集成材を使用し耐火性能をもたせる為に用いられる耐火性能材は規格化されたものではなかったため、鉄骨造・木造において建物の主要構造部の仕上を集成材とし、耐火性能をもたせる為には、コスト面・手間面の負担の制約があった。【解決手段】 本発明は耐火材として集成材を使用する場合において、燃えしろ部分となる集成材部分と燃えどまり部分となる不燃材の組み合せを板材とし、又この耐火性能を建築基準法の規定により規格化し、鉄骨造・木造の主要構造部の耐火材の仕上に集成材を使用する際のコスト面・手間面の負担を軽減し、耐火性能をもたせる場合に積極的な木材の使用が可能となる。【選択図】図2
