Fittings in adhesive joints on rectangular spikes
Gluing wood blanks along the length of rectangular spikes is a promising method of splicing due to its efficiency and performance, but requires scientific justification of the choice of landings in the connection of the spike-eye. The aim of the study is to substantiate the range of landings for connections along the length of multiple rectangular spikes. Analysis of the existing requirements for the choice of landings in standard connections showed that the standards regulate the tension in the joint spike-eye from 0 to 0.3 mm, but not all recommended in the reference literature landing meet this requirement. The calculation of fittings was carried out on the basis of three methods: probabilistic, maximum-minimum, average tension. For stud thicknesses up to 3 mm fitting H13/k13 and H13/za13 with tightness up to +0.27 mm are closest to the requirements of GOST 9330 and the recommendations of previous studies. The results of the work can be used in planning and conducting experimental studies of the strength of adhesive joints on rectangular spikes.
