摘要

本文的目的是研究大气条件对结构螺栓组中高压螺栓紧固性能的影响。本文介绍了对某型号螺栓组进行的试验试验结果。在组装前，根据指定的六个不同条件，将连接集的部件存储四周。纸、纸板箱和防腐蚀箔被用作对大气条件的保护。还考虑了未组装和组装螺栓组的行为。分析了摩擦系数随夹紧力和螺栓组储存条件的变化规律。这既适用于螺纹表面上连接元件之间的接触，也适用于螺栓头与螺母和垫圈的轴承表面之间的区域。

Effect of Atmospheric Conditions on the Tightening Behaviour of HV Galvanised Bolts in Structural Bolt Sets

The aim of this article is to investigate the effect of atmospheric conditions on the tightening behaviour of HV bolts in structural bolt sets. The article describes the results of experimental tests carried out for bolt sets of a selected type. The parts of the joined sets were stored according to the specified six different conditions for four weeks before assembly. Paper, cardboard boxes and anticorrosion foils were used as protection against atmospheric conditions. The behaviour of unassembled and assembled bolt sets was also taken into account. The variation in the friction coefficient depending on the clamping force and storage conditions of the bolt sets was demonstrated. This applies both to the contact between the joining elements on the threaded surfaces and to the area between the bolt head and the bearing surface of the nut and washer.
