LAMINATED WOOD
To provide a laminated wood material having high shear strength while ensuring fire resistance.SOLUTION: A wood laminate 10 of the present invention is a laminated wood made by laminating and adhering multiple sawn boards 11 cut from wood. A reinforcing member 20 extending vertically is provided inside the wood laminate 10, and the bottom edge of the reinforcing member 20 is located a predetermined dimension above the lower end surface of the wood laminate 10. According to the present invention, the wood laminate is provided with a reinforcement 20 extending vertically inside the wood laminate 10, the reinforcement 20 resists slippage between the sawn plates 11, that is, horizontal shear force, so that the shear strength of the woody laminate 10 can be enhanced. The bottom edge of the reinforcement 20 is positioned a predetermined dimension above the bottom surface of the wood laminate 10, so that even if a fire breaks out below the wood laminate 10 and the bottom portion of the wood laminate 10 burns, this heat can be prevented from being transmitted to the upper part of the wood laminate 10 through the reinforcing material 20, and the fire resistance performance of the wood laminate 10 can be ensured.SELECTED DRAWING: Figure 2
【課題】耐火性能を確保しつつせん断強度の高い木質積層材を提供すること。【解決手段】木質積層材１０は、木材から切り出したひき板１１を複数積層して接着した集成材である。木質積層材１０の内部には、上下に延びる補強材２０が設けられ、補強材２０の下端は、木質積層材１０の下端面から所定寸法上方に位置している。本発明によれば、木質積層材１０の内部に上下に延びる補強材２０を設けたので、この補強材２０が、ひき板１１同士のずれ、つまり水平せん断力に抵抗するから、木質積層材１０のせん断強度を高めることができる。また、補強材２０の下端を木質積層材１０の下端面から所定寸法だけ上方に位置させたので、木質積層材１０の下方で火災が発生して木質積層材１０の下部が燃えても、この熱が補強材２０を伝って木質積層材１０の上部に伝わるのを防止でき、木質積層材１０の耐火性能を確保できる。【選択図】図２
