Abstract: “The article describes a development of a new carpentry join suitable for reconstructions of timber structures; it is possible to replace only damaged parts of wooden beam with help of the joint. The mechanical behavior of the joint was analyzed in details. The inclined faces transfer the direction of loading and use of less stiff wooden dowels allows better distribution of stresses. The design methodic has been created so that the maximum of joint potential is used safely.”
