DEVICE FOR JOINING METAL SETS

摘要

The invention relates to a device for connecting metal sets, meant for the mining supports in the mining industry. The device for joining metal sets ensures the controlled clamping of the metal sections by placing some clamps (1 and 2) arranged in pairs on both sides of some sections (A and B), each pair comprising an upper clamp (1) guided inside along the upper section (A) and a lower clamp (2) bearing at the outer part the shoulder of the lower profile (B). The clamps (1 and 2) interlock at their end opposed to the sections (A and B) and are secured by mounting the end of the lower clamp (2) in a hole cut in the end of the upper clamp (1).
