Fixture for securing a balustrade

Abstract

A fixture for securing a glass balustrade to masonry comprises at least two panes of glass forming a safety glass panel and a U-section rail in which the panes of glass are secured by means of a coat of adhesive filled into the inside surfaces of legs and a bar of the U-section rail, so as to provide reliable protection against falling, and which absorbs forces acting on the balustrade by mechanical means and passes the forces on to the masonry and offers an adjusting means in order to allow the balustrade to be aligned plumb.

1 . A fixture ( 1 ) for securing a glass balustrade ( 2 ) to masonry ( 12 ) as protection against falling, comprising at least two panes of glass ( 3 ,  4 ) forming a safety glass panel ( 3 ,  4 ,  5 ) and a U-section rail ( 7 ) in which the panes of glass ( 3 ,  4 ) are secured by means of a coat of adhesive ( 11 ) filled into the inside surfaces of legs ( 8 ,  9 ) and a bar ( 10 ) of the U-section rail ( 7 ),
 wherein   at least one support plate ( 13 ) is attached to the U-section rail ( 7 ) and extends parallel to the masonry ( 12 ) and is aligned in an extension to a force (F) acting essentially horizontally on the balustrade ( 2 ), and said support plate ( 13 ) is connected to an adjusting device ( 15 ) by means of which a distance between said support plate ( 13 ) and the masonry ( 12 ) can be adjusted, and support plate ( 13 ) is secured to the masonry ( 12 ).   
     
     
         2 . The fixture in accordance with  claim 1 ,
 wherein   the adjusting device ( 15 ) comprises a threaded pin ( 16 ), a free end of which is in contact with the masonry ( 12 ), directly or by means of intermediate elements, or is screwed into the masonry ( 12 ), preferably in a threaded hole ( 28 ), a through-hole ( 20 ) is worked into said support plate ( 13 ), and the threaded pin ( 16 ) passes through the through-hole ( 20 ), and a female thread is worked into the through-hole ( 20 ), or a box-shaped channel ( 18 ) is provided adjacent to it, into which a nut ( 19 ) or a threaded block is inserted, and said threaded pin ( 16 ) is screwed into the female thread or into the nut ( 19 ) or threaded block.   
     
     
         3 . The fixture in accordance with  claim 1 ,
 wherein   support legs ( 14 ) spaced apart from one another are formed on said support plate ( 13 ) which faces towards the masonry ( 12 ), and the adjusting device ( 15 ) is arranged between two adjacent support legs ( 14 ).   
     
     
         4 . The fixture in accordance with  claim 1 ,
 wherein   grout ( 25 ) is filled in between said support plate ( 13 ) and the masonry ( 12 ), and the grout ( 25 ) and an expanding wall plug ( 16 ′) which passes through the support plate ( 13 ) secure the balustrade ( 2 ) onto the masonry ( 12 ).   
     
     
         5 . The fixture in accordance with  claim 2 ,
 wherein   at least one support bar ( 21 ) running at an angle, or a holding plate ( 21 ′) extending over the entire length of the balustrade ( 2 ′) is arranged between a free end of said support plate ( 13 ) and a free end of an outwardly pointing leg ( 8 ) of the U-section rail ( 7 ), and the support bar ( 21 ) or the holding plate ( 21 ′) absorbs forces (F) acting on the balustrade ( 2 ).   
     
     
         6 . The fixture in accordance with  claim 5 ,
 wherein   one or more recesses ( 22 ) is/are worked into the holding plate ( 21 ′), and running flush with the adjusting device ( 15 ).   
     
     
         7 . The fixture in accordance with  claim 1 ,
 wherein   the two legs ( 8 ,  9 ) of the U-section rail ( 7 ) which run vertically are the same size, or the leg ( 8 ) pointing towards the incoming force (F) is smaller than the leg ( 9 ) located opposite to the incoming force.   
     
     
         8 . The fixture in accordance with  claim 3 ,
 wherein   said support plate ( 13 ) projects at right angles from the U-section rail ( 7 ) and the underside of said support plate ( 13 ) facing the masonry ( 12 ) is arranged in one plane with the bar ( 10 ) of the U-section rail ( 7 ) or the support legs ( 14 ) projecting from the support plate ( 13 ) extending in the same plane as the bar ( 10 ) of the U-section rail ( 7 ).   
     
     
         9 . The fixture in accordance with  claim 5 ,
 wherein   said support plate ( 13 ), the U-section rail ( 7 ) and the support bar ( 21 ) or the holding plate ( 21 ′) are configured as a one-piece component.
