国産材を使った新しい木造建築の開発 : (ファスナーを使用した混合構造の研究)

Abstract

The purpose of this study is that the wood is used as st ructural material factory of larg e-span steel Structure were mainly low-rise warehouses， and stores. Since the conifer grows upright. It can be used as column material is suitable. To be used as material for this beam，the effectiveness of the steel is not enough. The lar se spam loe-tise structure pillar for this-wood， beams-a mixture of steel frame structure is valid. Challenge to achieve such a mixed structure the development of wood and steel fasteners are joined to become the most important issue The frrst study aimed to clariy the basic properties of the fastener and its development. Because the strength that was enough for a fastener was recognized， the development of the joint using the fastener became the important problem to realize mixed structure. IVY fastener and the end plate join t using the iron plate in the joint. Generally， a bolt of the wood structure is with a pin joint. Then strut and angle brace material s are necessary. Therefore materials increase， and construction becomes difficult. In addition， the cost rises ， too. However， the end plate joint can constitute the housing which construction is simple， and is extremely high in rigidity. In addition， it does not need strut and angle brace materials and can make a big window with wooden construction and can reali ze a free facade. It is finally aimed for the realization of the wooden bent using thinning materials and thi s method of construction.
