Method for fixing insulating boards and corresponding dowel

Abstract

So that the method is also suitable for old construction, initially pins which have a pin body ( 2 ) and a pin head ( 7 ) are offset in such number on the wall that a plurality of pins are provided for each insulating plate ( 10 ). Then one applies an adhesive ( 9 ) to the pin head ( 7 ) of the pin and optionally onto the wall ( 5 ) and then one presses the heat-insulating board ( 10 ) thereagainst. It is advantageous for the adhesive area ( 7 ) of the pin to have openings through which the adhesive ( 9 ) can pass to the back side. The adhesive areas ( 7 ) can be especially star-shaped. It is however also appropriate to provide fiberglass grids as pin heads. For the pins of the invention it is characteristic that spreading zones or pin heads be adjacent one another. The pins can also have flexible reinforcing plates.

1 . A method of attaching an insulating board to a wall or a roof, especially for retrofitting old construction with insulating board, characterized in that one offsets in the wall or the roof such number of pins which have pin heads that a plurality of pins are provided for each insulating board, one applies an adhesive to the pin heads of the pins and optionally to the wall or the roof and then the insulating board is pressed against the adhesive on the pin heads and wall or roof.  
     
     
         2 . The method according to  claim 1  characterized in that one uses pins whose pin heads have openings to allow passage of the adhesive to the back sides of the pin heads, especially pins with star-shaped pin heads.  
     
     
         3 . The method according to  claim 1  characterized in that one uses pins whose pin heads are fiberglass grids.  
     
     
         4 . A pin for fastening insulating boards to a wall or a roof, especially for retrofitting application to old construction, whereby the pin has a spreading zone and a pin head and whereby the pin head has a plurality of arms extending in a star shape, characterized in that the spreading zone ( 11 ) and the pin had ( 13 ) are neighboring.  
     
     
         5 . The pin according to  claim 4  characterized in that a flexible reinforcing plate ( 16 ) is stuck onto the pin ( 1 ) and lies in the mounted state between the wall or the roof and the arms ( 14 ) of the pin ( 1 ).  
     
     
         6 . The pin according to  claim 4  or  5  characterized in that a ring ( 15 ) is fixed on the arms ( 14 ) to mark the adhesive area.
