摘要:
 为了探究棉秆重组方材在家具制造业中的可行性，以棉秆重组方材为基材，选取贯通椭圆榫接合、不贯通椭圆榫接合、双圆榫接合及偏心连接件接合4种典型木质家具结点接合方式，以L型和T型构件为主要形式，对8种形式的部件进行结点抗弯强度的试验研究。结果表明：相同接合方式条件下，棉秆重组方材L型和T型部件的破坏弯矩均表现为：橡胶木＞棉秆重组方材＞中密度纤维板＞刨花板，表明其能够满足板式家具的牢固性要求；棉秆重组方材的T型部件的破坏弯矩均高于L型部件，因此在结构允许的情况下，棉秆重组方材家具应尽可能采用T型结构；棉秆重组方材2种结构试件的破坏弯矩均表现为整体式贯通椭圆榫接合＞整体式不贯通椭圆榫接合＞双圆榫接合＞偏心连接件接合，因此，棉秆重组方材家具应优选贯通椭圆榫接合方式，其中偏心连接件应尽量避免在承重部位使用。
Abstract:
 In order to explore the feasibility of cotton stalk square lumber for furniture manufacturing and provide technical basis to square lumber furniture design,cotton stalk reconstituted square lumber (CSRSL) was used as the base material.T- and L-form were used as the basic pine-wood components.Four kinds of traditional frame joints bonding modes were used to determine the node joining strength,such as eccentric fittings joint,run-through mortise and tenon joint,hidden mortise and tenon joins,and double dowels joint.The results showed that under the same joint way,the node bending strength of L- and T-form components were in the order of rubber wood > reconstituted square lumber made from cotton stalk > medium density fiberboard > particleboard,indicating that CSRSL could satisfy the strength requirement of wood-based panel furniture.The joint bending strength of CSRSL with T-form component was higher than that of the L-form component,indicating that T-form should used.The values of bending strength of both components were in the order of run-through mortise and tenon joints > hidden mortise tenon joints strength > double dowels joints > eccentric fittings joints strength.Therefore,when using CSRSL to design furniture,it was preferred to use run-through mortise and tenon joints to eccentric fittings joints.
