发明名称 COLUMNAR BLOCK FENCE SYSTEM
摘要 <p>A system of columnar blocks and stacking blocks interlock with each other in the construction of a pilaster or column and a fence panel, respectively, for use in a fence. The columnar blocks are generally square and the stacking blocks are generally rectangular. The columnar block faces may contain one or more slots to give a column an appearance of a masonry joint. Blocks have at least one interlocking element that permits a positive connection between courses of the blocks when the interlocking element is received in an overlying block.</p>
