Abstract
Joints with threaded rods glued in wood are a technique of great interest for both new projects and the restoration of old structures. Our research team has developed a comprehensive study, both theoretical and experimental, on joints for different types (sawn and laminated) and species (conifers and deciduous) of wood. This article shows the newsystem developed to improve anchoring efficiency. The newsystem involves a widening in the bore that is filled with epoxy adhesive, which creates a bulb that can increase the load capacity of the anchorage and the ductility of the joint. The types of bits designed to create the inner bulb easily are likewise detailed. The article also shows the results of the experimental work performed, comparing the load values and failure modes of this type of joint with the traditional system of straight anchoring.
