摘要
The mechanical coupling system, especially for cylindrical concrete components used in construction, consists of using a threaded sleeve (3) to couple the two ends (4,5) of the components (1,2), which are also threaded. Prior to fitting the components together with the sleeve, the ends of the components are reduced in diameter, for the length covering their threads, by cooling them. The ends of the components may also be pre-stressed, for the length of their threads, prior to joining, using an effort of between 70 and 95 per cent of the components' limit of elasticity.
