Flat roof construction, method of producing a flat roof construction and storm safety element

Abstract

The invention relates to a storm protection element of a post which passes through a flat roof covering. In particular, the element is designed as a hold-down disk or plate with an opening surrounded by spring-elastic claws which are designed so as to determine an inner contour of the opening, the inner contour being attached to the outer contour of the post to be secured. The storm protection element can be pushed onto the post from the free end of the post against the elastic resistance of the claws, whereas the claws wedge against the post when a force acts in the opposite direction and thus fix the storm protection element in the position reached by the element upon being pushing onto the post.

1 . A flat roof construction with a flat roof covering and at least one post extending through this covering, wherein a storm prevention element is attached to the post is constructed as a hold-down disk or hold-down plate with an opening that is surrounded by spring-elastic claws in such a manner that these claws determine an inside contour of the opening that is adapted to the outside contour of the post to be secured, and that the storm prevention element can be pushed from the free end of the post against the elastic resistance of the claws onto the post, whereas the claws wedge against the post when a force acts in the opposite direction and thus fix the storm protection element in the position reached by this element upon being pushed onto the post. 
     
     
         2 . The flat roof construction according to  claim 1 , wherein the storm protection element attached to the post is covered by a watertight covering whose shape corresponds in a top view in particular to the shape of the storm protection element and whose dimensions are slightly greater than those of the storm protection element, wherein the covering is adhered or welded outside of the circumferential edge of the storm protection element to the surface of the flat roof covering. 
     
     
         3 . A storm protection element of a flat roof construction according to  claim 1 , constructed as a hold-down disk or hold-down plate with an opening that is surrounded by spring-elastic claws in such a manner that these claws determine an inside contour of the opening that is adapted to the outside contour of the post to be secured, and that the storm prevention element can be pushed from the free end of the post against the elastic resistance of the claws onto the post, whereas the claws wedge against the post when a force acts in the opposite direction and thus fix the storm protection element in the position reached by this element upon being pushed onto the post. 
     
     
         4 . The storm protection element according to  claim 3 , constructed as a circular plastic disk with a central opening. 
     
     
         5 . The storm protection element according to  claim 3 , wherein the claws are designed as projections of a metallic fixing ring that is permanently set into the opening. 
     
     
         6 . The storm protection element according to  claim 3 , wherein the claws enclose an acute angle with the holding plane of the storm protection element at least in sections, in particular in a section at or in the vicinity of their free ends. 
     
     
         7 . The storm protection element according to  claim 6 , wherein the angle between the claws and the holding plane is between 5° and 45°, especially between 10° and 30°. 
     
     
         8 . The storm protection element according to  claim 3 , wherein the thickness constantly increases from the edge to the opening. 
     
     
         9 . The storm protection element according to  claim 3 , with a thickened area that is offset in a graduated manner toward the edge and extends around the opening. 
     
     
         10 . A method for producing a flat roof construction comprising: a storm protection element according to  claim 3  is pushed and pressed onto at least one part of the posts penetrating the flat roof covering, in particular onto each post, and onto the surface of the flat roof covering. 
     
     
         11 . The method according to  claim 10 , wherein at least one section of each post, which section is in the vicinity of the covering, and of the surroundings of the post are provided with a watertight covering while covering the storm protection element. 
     
     
         12 . The method according to  claim 10 , wherein the covering is adhered or welded outside of the circumferential edge of the storm prevention element to the surface of the flat roof covering.
