UNITS OF PASSAGE OF SOUNDPROOF PANEL AND METHOD FOR PRODUCTION THEREOF

摘要

FIELD: machine building.SUBSTANCE: soundproof panel passage assemblies are made in the plate from elastic material with passing through its shaped holes long items. Sector in the plates out of elastic material envelope long article along the perimeter as collar and are fixed on them. Perimeter of holes forming inner perimeter sectors is less than perimeter passing through them of long articles. Method of producing units passage consists in the fact that on plates from elastic material is marked contours holes corresponding to the perimeter of long articles and smaller holes. On the circuits of holes for passage units, marking sectors straight lines. Cut holes. Sectors are made cuts along the marking lines. Space between the sectors are filled with sealant for sector an additional layer of sealant.EFFECT: higher tightness and sound insulation in places of long articles.2 cl, 3 dwg
