Crash barrier and method for installing same

Abstract

A crash barrier is provided including: a first outer layer; a second outer layer spaced apart from the first outer layer; and a plurality of spacer blocks which are arranged between the outer layers, the crash barrier being divided along its longitudinal extent into at least two partial sections which are joined by at least one connecting element which has a first longitudinal section, a second longitudinal section and a third longitudinal section, the first and third longitudinal sections being designed to each be connected to a partial section, and the second longitudinal section connecting the first and third longitudinal sections to one another. A method for installing such a crash barrier is also provided.

What is claimed is: 
     
         1 . A crash barrier comprising:
 a first outer layer;   a second outer layer that is spaced apart therefrom; and   a plurality of spacer blocks which are arranged between the outer layers,   wherein the crash barrier is divided along its longitudinal extent into at least two partial sections, which are joined by at least one connecting element that has a first longitudinal section, a second longitudinal section and a third longitudinal section,   wherein the first and third longitudinal sections are designed to each be connected to a partial section of the crash barrier, and the second longitudinal section connects the first and third longitudinal sections to one another,   wherein the outer side of the second outer layer is designed and intended to be connected to at least one post.   
     
     
         2 . The crash barrier of  claim 1 , wherein the second longitudinal section of the connecting element has a cross-sectional area which corresponds to between about 50% and about 80% of the cross-sectional area of the first and third longitudinal sections. 
     
     
         3 . The crash barrier of  claim 1 , wherein the first and third longitudinal sections of the connecting element have a round cross-section and/or wherein the first and/or third longitudinal sections of the connecting element is at least partially provided with an external thread. 
     
     
         4 . The crash barrier of  claim 1 , wherein the first longitudinal section, the second longitudinal section and the third longitudinal section of the connecting element are manufactured in one piece, and the second longitudinal section is produced by machining. 
     
     
         5 . The crash barrier of  claim 1 , wherein the first outer layer and/or the second outer layer and/or the plurality of spacer blocks comprise wood or a wood-based material, or
 wherein the first outer layer and/or the second outer layer and/or the plurality of spacer blocks comprise glued wood and/or laminated wood and/or laminated veneer lumber and/or laminated strand lumber.   
     
     
         6 . The crash barrier of  claim 1 , wherein the spacer blocks at the end of a partial section have at least one bore running in the longitudinal direction, in which bore the first or third longitudinal section of the connecting element is guided. 
     
     
         7 . The crash barrier of  claim 6 , wherein the bore is between about 5% and about 25% or between about 10% and about 20% or between about 11% and about 16% larger than the diameter of the first and third longitudinal sections of the connecting element. 
     
     
         8 . The crash barrier of  claim 6 , wherein the bores are designed as through bores in the spacer blocks, the first and third longitudinal sections of the connecting element being longer than the extension of the spacer blocks, so that the first and third longitudinal sections can be screw-connected at the exit from the spacer blocks. 
     
     
         9 . The crash barrier of  claim 1 , wherein the first outer layer and/or the second outer layer have a thickness measured in the horizontal direction of about 50 mm to about 200 mm or of about 60 mm to about 100 mm or of about 70 mm to about 90 mm and/or
 wherein the first outer layer and/or the second outer layer have a height measured in the vertical direction of about 280 mm to about 370 mm or of about 295 mm to about 350 mm.   
     
     
         10 . The crash barrier of  claim 1 , wherein the first outer layer has a height measured in the vertical direction which is greater by about 10 mm to about 50 mm than that of the second outer layer. 
     
     
         11 . The crash barrier of  claim 1 , wherein the spacer blocks have a height measured in the vertical direction, which corresponds to the height of the outer layers and/or
 wherein the spacer blocks have a thickness measured in the horizontal direction of about 90 mm to about 150 mm or of about 90 mm to about 140 mm or of about 110 mm to about 130 mm and/or   wherein the spacer blocks have a length measured in the longitudinal direction of the crash barrier of about 200 mm to about 300 mm or of about 300 mm to about 600 mm.   
     
     
         12 . The crash barrier of  claim 1 , further comprising a plurality of posts pursuant to RAL-RG 620. 
     
     
         13 . A method for installing a crash barrier, comprising:
 inserting at least two posts;   fastening a crash barrier to the posts, the crash barrier including
 a first outer layer, 
 a second outer layer that is spaced apart therefrom, and 
 a plurality of spacer blocks which are arranged between the outer layers, 
 wherein the crash barrier is divided along its longitudinal extent into at least two partial sections, which are joined by at least one connecting element that has a first longitudinal section, a second longitudinal section and a third longitudinal section, 
 wherein the first and third longitudinal sections are designed to each be connected to a partial section of the crash barrier, and the second longitudinal section connects the first and third longitudinal sections to one another, 
 wherein the outer side of the second outer layer is designed and intended to be connected to at least one post; and 
 joining the partial sections with the at least one connecting element; and 
 connecting the outer side of the second outer layer to the posts. 
   
     
     
         14 . The method of  claim 13 , wherein at least one post complies with RAL-RG 620 and/or wherein the crash barrier is fastened by screws. 
     
     
         15 . The method of  claim 13 , further comprising: chamfering at least one end of at least one partial section and/or at least one spacer block at the end of a partial section by machining.
