STRUCTURAL MEMBER

PROBLEM TO BE SOLVED: To provide a structural member having strength against not only load but also bending.SOLUTION: A structural member comprises: a plate substrate 2 made of inorganic materials comprising cement; a PC steel bar 31 arranged at inner section of the plate substrate 2; wood plates 4 arranged in an opposing manner respectively to front side 2A and backside 2B of the plate substrate 2; and connecting member 5 which connects these wood plates 4 and penetrates the plate substrate 2. Load in a direction orthogonal to a longitudinal direction of the structural member may be rigidly supported with the plate substrate 2 which is made of the inorganic materials and subjected to be prestressed with the PC steel bar 31. By virtue of elastic force of the wood plates 4 connected each other with connecting member 5, deformation caused by bending by the plate substrate 2 may be prevented. 【課題】荷重だけでなく座屈にも強い構造部材を提供する。【解決手段】セメントを含む無機材料で成形された板状基材２と、この板状基材２の内部に設けられたＰＣ鋼棒３１と、板状基材２の正面２Ａと背面２Ｂにそれぞれ対向配置された木質板材４と、これらの木質板材４を連結するとともに板状基材２を貫通する連結部材５とを備えた。構造部材の長手方向に直交する方向にかかる荷重を無機材料からなりＰＣ鋼棒３１でプレストレスがかけられた板状基材２で強固に支持できる。連結部材５で互いに連結されている木質板材４がもつ弾性力によって、板状基材２が座屈によって変形することを防止することができる。【選択図】図２
