Attachment means for connecting plane material combinations in dry construction

Abstract

The present invention relates to attachment means ( 1 ) for connecting plane components in dry construction, in particular for fixing two-dimensional construction material to a metallic substructure, having a shaft ( 2 ) on one end region of which a point ( 3 ) and on the other end region of which a head ( 4 ) are formed, a fine thread ( 5 ) being formed on the shaft ( 2 ) in order to increase extraction values of the attachment means ( 1 ), at least in regions, a number of grooves ( 6 ) being provided on the shaft ( 2 ) which extend substantially parallel to the central axis (X) of the shaft ( 2 ).

1 - 9 . (canceled) 
     
     
         10 . A method for connecting plane components in dry construction, comprising the steps of:
 a) providing a screw nail comprising a shaft having a first end forming a point and a second end forming a head, a fine thread being formed on the shaft, and grooves being provided on the shaft and extending substantially parallel to a central axis of the shaft; and   b) securing a planar construction material and a metallic substructure underlying the construction material by driving the screw nail, without rotation about the central axis, through the construction material and into the metallic substructure.   
     
     
         11 . The method of  claim 10 , wherein step b) is accomplished by means of an automatic nail gun device. 
     
     
         12 . The method of  claim 10 , wherein the grooves have a depth which corresponds to a depth of the fine thread. 
     
     
         13 . The method of  claim 10 , wherein the grooves are evenly distributed over the peripheral surface of the shaft. 
     
     
         14 . The method of  claim 10 , wherein the grooves are arranged such that they extend from the point over a lower partial section of the shaft. 
     
     
         15 . The method of  claim 10 , wherein the grooves have a semicircular, V-shaped or U-shaped cross-sectional profile. 
     
     
         16 . The method of  claim 10 , wherein the fine thread has self-cutting thread flanks. 
     
     
         17 . The method of  claim 10 , wherein the fine thread is in the form of a flat saw tooth thread or is double threaded. 
     
     
         18 . The method of  claim 10 , wherein the screw nail is heat treated. 
     
     
         19 . The method of  claim 10 , wherein the grooves are arranged such that they extend from the point over a lower partial section of the shaft. 
     
     
         20 . The method of  claim 10 , wherein the fine thread has self-cutting thread flanks. 
     
     
         21 . The method of  claim 10 , wherein the screw nail is austempered.
