Block and block connector

Abstract

A block and a block connector capable of easily constructing a concrete retaining wall in relatively short time are provided. A block 10 comprises a plane front side 18 and a plurality of fixing portions 12 formed on the rear side of the front side 18 to project from the block 10 . A block 20 comprises a plane front side 28 slanted toward a rear side thereof and a plurality of fixing portions 22 formed on the rear side of the front side 28 to project from the block 20. A block connector 50 comprises a connecting member 51 having a predetermined length and holding members 52 that are detachably jointed to joint portions 51 a on both sides of the connecting member 51. The fixing portions 12 and 22 of the blocks 10 and 20 arranged with their rear sides opposed to each other are held by holding portions 52 d of the block connector 50 , thereby connecting the blocks 10 and 20 at a predetermined interval therebetween.

       2 . A block according to claim I further comprising joint means for jointing the plurality of the blocks to prevent transverse displacement of the block relative to the adjacent block, the joint means being formed on a top, bottom, right side, and left side surfaces of the block.  
   
   
       3 . A block according to  claim 2 , wherein the joint means is a concave groove or a convex line which can be engaged with the convex line or the concave groove that is the joint means of the adjacent block, respectively.  
   
   
       4 . A block for forming a wall structure by arranging a plurality of the blocks to tightly contact with each other in vertical and horizontal directions, the block comprising a plane front side to form a continuous flat surface on an outside of the wall structure, at least one fixing portion for receiving a block connector, the fixing portion being formed on a rear side of the front side at a predetermined interval and projecting from the block, and a cut-out portion extending to the rear side formed on a part of a periphery of the front side of the block.  
   
   
       5 . A block according to  claim 4  further comprising joint means for jointing the plurality of the blocks to prevent transverse displacement of the block relative to the adjacent block, the joint means being formed on a top, bottom, right side, and left side surfaces of the block.  
   
   
       6 . A block according to  claim 5 , wherein the joint means is a concave groove or a convex line which can be engaged with the convex line or the concave groove that is the joint means of the adjacent block, respectively.  
   
   
       7 . A block for forming a wall structure by arranging a plurality of the blocks to tightly contact with each other in vertical and horizontal directions, the block comprising a plane front side to form a continuous flat surface on an outside of the wall structure, and at least one fixing portion for receiving a block connector, the fixing portion being formed on a rear side of the front side at a predetermined interval and projecting from the block, and the front side being slanted leaning toward the rear side of the block.  
   
   
       8 . A block according to  claim 7  further comprising joint means for jointing the plurality of the blocks to prevent transverse displacement of the block relative to the adjacent block, the joint means being formed on a top, bottom, right side, and left side surfaces of the block.  
   
   
       9 . A block according to  claim 8 , wherein the joint means is a concave groove or a convex line which can be engaged with the convex line or the concave groove that is the joint means of the adjacent block, respectively.  
   
   
       10 . A block for forming a wall structure by arranging a plurality of the blocks to tightly contact with each other in vertical and horizontal directions, the block comprising a plane front side to form a continuous flat surface on an outside of the wall structure, at least one fixing portion for receiving a block connector, the fixing portion being formed on a rear side of the front side at a predetermined interval and projecting from the block, and a cut-out portion extending to the rear side formed on a part of a periphery of the front side of the block, the front side being slanted leaning toward the rear side of the block.  
   
   
       11 . A block according to  claim 10  further comprising joint means for jointing the plurality of the blocks to prevent transverse displacement of the block relative to the adjacent block, the joint means being formed on a top, bottom, right side, and left side surfaces of the block.  
   
   
       12 . A block according to  claim 11 , wherein the joint means is a concave groove or a convex line which can be engaged with the convex line or the concave groove that is the joint means of the adjacent block, respectively.  
   
   
       13 . A block connector for connecting a block for forming a wall structure by arranging a plurality of the blocks to tightly contact with each other in vertical and horizontal directions, the block comprising a plane front side to form a continuous flat surface on an outside of the wall structure, and at least one fixing portion for receiving the block connector, the fixing portion being formed on a rear side of the front side at a predetermined interval and projecting from the block, the block connector comprising a holding portion for detachably holding the fixing portion of the block and a connecting member having a predetermined length, the holding portion being provided on both ends of the connecting member.  
   
   
       14 . A block connector claimed in  claim 13 , wherein a plurality of the holding portions are provided on each of the both ends of the connecting member at a predetermined interval.  
   
   
       15 . A block connector claimed in  claim 14 , wherein the interval between the plurality of the holding portions is substantially the same as the interval between the plurality of the fixing portions provided on the block.
