FIELD: construction.
SUBSTANCE: invention relates to a glass plastic profile, to the method for manufacture of this glass plastic profile and to a plant for manufacturing of a glass plastic profile according to the invention. The technical result is achieved by the method of using a profile made of glass fibres used to strengthen a mine wall, including stages, at which glass fibres are impregnated with polymer resin. Then glass fibres are aligned in longitudinal direction, and these fibres are placed for making an axially stretched profile. Then the glass fibres of the profile that are most remote from the axis are compressed at axial intervals with the help of a thread-like element of compression for giving corrugated shape, corresponding to the corrugate shape of the finished profile, a combination of the external surface of the profile and the thread-like compression element. Besides, the external surface of the profile has a sinusoidal shape relative to the axial plane of the cross section. After that the polymerisation process is carried out in the profile.
EFFECT: improved resistance to pulling out of manufactured profiles and reduced labour intensiveness of their manufacturing.
