Block having surface layer piece attached thereto

Abstract

A paving block with a rubber piece made from, e.g., a used tier, for reducing echoes, noise, wear, icing on the block surface, adhering force of ice, shocks in collisions, etc. The block having high dimensional accuracy and comprising strong rubber piece that does not peel away fro a long period is provided by a simple and low-cost method. The method is applied to provide diverse construction blocks to which materials, other than rubber, with various characteristics are attached. A square piece of rubber is cut off from a tire with non-uniform, uneven thickness caused by wear. This piece of rubber is made a surface layer piece ( 1 ) of a block, and asphalt that functions as a bonding portion ( 2 ) is applied to the back side of the surface layer piece ( 1 ). Concrete is placed directly on the asphalt as a curing body ( 3 ). The concrete placement thickness is adjusted so that the entire block has a predetermined thickness and the concrete is cured. Using a holding arm ( 7 ), a net like member ( 5 ), a separator ( 33 ), a joint ( 34 ), etc. can increase the strength of the block.

1 . A block having a surface layer piece attached thereto which comprises conditions as follows: 
 a) a surface layer piece covers at least a part of the block surface when used;    b) a said piece has properties desired at the position attached to;    c) a bonding portion consists of viscosity of asphalt-like materials and/or delayed adhesion    d) said bonding portion contacts directly with the back side of said piece;    e) hardening material like concrete, hardening for a period of time, is placed directly on said bonding portion to make a curing body;    f) said hardening material is placed to shape into said blocks of designed sizes;    g) said hardening material has strength higher than designed one;    h) said surface layer piece and said curing body are unified with said bonding portion with adhesion higher than designed one.    
   
   
       2 . The block having a surface piece attached thereto as claimed in  claim 1 , wherein a joint ( 34 ), formed in the joint space ( 4 ) around the surface layer piece ( 1 ), is connected to curing body ( 3 ) with adhesion or burying its part.  
   
   
       3 . The block having a surface piece attached thereto as claimed in  claim 1 , wherein the back side of the surface layer piece ( 1 ) has a groove or a holding arm ( 7 ) to make undulation.  
   
   
       4 . The block having a surface piece attached thereto as claimed in  claim 1 , wherein the adjacent blocks are connected with a net-like member ( 5 ).  
   
   
       5 . The block having a surface piece attached thereto as claimed in  claim 1 , wherein the lateral line ( 11 ), parallel to the rotating axis of the wheel tire, intersects with a right angle the end line ( 12 ) of the surface layer piece (I) in the adjacent block.  
   
   
       6 . The block having a surface piece attached thereto as claimed in  claim 1 , wherein plural layers are sandwiched to be make one.  
   
   
       7 . The block having a surface piece attached thereto as claimed in  claim 1 , wherein a heating material such as carbon which can generate electrical heat is placed in bonding portion ( 2 ).  
   
   
       8 . The block having a surface piece attached thereto as claimed in  claim 1 , wherein a separator ( 33 ), made of a plane and intersecting with the surface of said surface layer piece, is placed in said curing body.
