The chapter describes a recently introduced method of design of all-wooden joints intended for replacement of decayed joists in historical wooden constructions. The described document is the result of applied research conducted at ITAM AS CR. The method description consists of both design and technological part. The first one describes the design rules including bearing capacity and deflection assessment, the latter prescribes good approaches to manufacturing of the joint which are needed for good service of the joint. Discussed is also the maintenance and control of the joints during their service life.\n
