Anti-sliding batten with preventing thermal expansion and its manufacturing method

Abstract

The present invention discloses that an anti-sliding batten with preventing thermal expansion being applied on that setting up a shield on a roof with the batten and comprising a plurality of projecting blocks spread on at least one surface of the batten with a suitable interval for any two adjacent projecting blocks. By means of the present invention, the friction between the anti-sliding batten and the shield is increased, hence two of them are tightly touched each other for promoting working safety; further, careless workers being sliding to fall down is then prevented and the phenomena of shrink and expansion are no longer exist.

What is claimed is:  
     
         1 . An anti-sliding batten with preventing thermal expansion being applied on that setting up a shield on a roof with the batten and comprising: 
 a plurality of projecting blocks spread on at least one surface of the batten with a suitable interval for any two adjacent projecting blocks.    
     
     
         2 . The anti-sliding batten with preventing thermal expansion as cited in  claim 1 , wherein the plural projecting blocks are regularly spread on the batten.  
     
     
         3 . The anti-sliding batten with preventing thermal expansion as cited in  claim 1 , wherein the batten is a plastic compound plate.  
     
     
         4 . The anti-sliding batten with preventing thermal expansion as cited in  claim 1 , wherein the shield is one of the following: light shield, plastic protection, ambient light hood and heat insulation plate.  
     
     
         5 . The anti-sliding batten with preventing thermal expansion as cited in  claim 1 , wherein the projecting blocks can be shaped one of the following: triangular, polygon, quadrilateral and irregularity.
