| Title of the article | The effectiveness of the use of glued threaded washers in the joints of wooden structures |
| Abstract. | Primary studies have shown that in the joints of wooden structures on threaded washers premature destruction of the adhesive seam occurs and the washers detach from the wooden element, due to the action of forces directed from the plane of the washers. It is proposed to compensate for these forces by additional compression of the junction node with overlays that are tightly adjacent to the connected elements of the node. The purpose of the research is to study the work of connecting wooden structures on glued threaded washers when compressing a node with steel linings. The objectives of the study are to conduct an experimental study of a series of samples to determine destructive loads and extreme deformations, to investigate the nature of the destruction of joint samples, to determine the feasibility of using this type of joint in wooden structures. Results. In order to study the nature of the work of the joint in question, experimental studies of a series of samples were carried out. Destructive loads are determined, deformation graphs are constructed. The factors influencing the destructive load and the mechanism of destruction of samples are investigated, the analysis of the effectiveness of the use of alternative methods of perception of the expansion of washers in the junction node is carried out. Conclusions. Tests have shown the general inefficiency of compression of the junction with steel plates. Since other ways of perceiving the spacer in washers will lead to a significant increase in the complexity of manufacturing and assembling the joint, it is concluded that the use of glued threaded washers in joints of wooden structures is ineffective. The analysis of the research results revealed the possibility of using screw-on threaded washers without the use of an adhesive composition, which will significantly reduce the manufacturing time of the structure. |
