Device for injecting liquid material into brick work, wood etc. - comprises two hollow cylinders screwed together with flexible, hollow sleeve clamped between which expands radially when cylinders tighten

摘要

The hollow cylindrical element is made up of two hollow cylinders (1,8) screwed together with threads (10,6) on each cylinder. At least one of the cylinders has an anchor (5) which is expansible in the radial direction when the cylinders are screwed together. The anchor is in the form of a flexible sleeve so that when the cylinders are screwed together, besides expanding radially, it also compresses in the longitudinal direction. There is a conically shaped stop (4) on one end of the forward cylinder (1) and a stop (7) on the end of the other cylinder. ADVANTAGE - Provides a positively sealed connection with the bore hole which can easily be removed again and can be used in many different types of bore holes.
