Unit fixing insulation to a wall
The object of the invention is a unit fixing insulation to the wall intended both for styrofoam insulation as well as for mineral wool insulation. A unit fixing insulation to a wall, according to the invention, is formed with the locating sleeve which is ended at one end with an expansion zone, and with a circular plate at the other end, whereas the locating sleeve houses an expansion element, preferably in the form of a screw. A unit characterized in that the expansion element has a head embedded permanently in the sleeve with an outer thread and a polygonal hole is provided within the sleeve, and the locating sleeve has a diameter with gradation, wherein a larger diameter is from the inlet side. Length of the locating sleeve from the step to its end is equal to or larger than the length U of the expansion element from the point of being connected to the sleeve to its end, whereas a larger inner diameter of a locating sleeve is larger than the outer diameter of the sleeve fixedly joined to an expansion element. The length of a larger inner diameter of the locating sleeve is equal to or longer than the length K0 of the sleeve fixedly joined to an expansion element.
1. A unit for attaching insulation to a wall, comprising:
a main body formed with a locating sleeve which is ended at one end with an expansion zone, and with a circular plate at an opposing end;
wherein the locating sleeve houses an expansion element;
wherein the expansion element defines a head embedded permanently in an expansion element sleeve with an outer thread and wherein said expansion element sleeve is directly joined with the expansion element;
wherein said expansion element sleeve defines a polygonal hole; and
wherein the locating sleeve has a variable diameter, wherein a larger first diameter is from the inlet side;
wherein a length of the locating sleeve from a step to its end is equal to or larger than a length of the expansion element measured from connection to said expansion element sleeve to an end of the expansion element;
whereas a larger inner diameter of the locating sleeve is larger than the outer diameter of the expansion element sleeve fixedly joined to an expansion element;
wherein the length of a larger inner diameter of the locating sleeve is equal to or longer than the length of the expansion element sleeve fixedly joined to an expansion element.
2. A fixing unit according to claim 1 , wherein the end of the locating sleeve comprises a ribbed outer surface slitted on both sides, wherein outermost slits are ended with circular openings.
3. The unit fixing insulation to a wall of claim 1 wherein the expansion element comprises a screw.
