发明名称 Plastic block retaining wall with attached keylock facing panels
摘要 An inexpensive, yet beautiful retaining wall may be formed with architecturally pleasing, coordinating or matching materials such as marble, granite, stone, metal or the like. Architecturally pleasing, thin decorative facing panels are attached to plastic blocks which have hollow spaces to be filled with gravel or the like. The retaining wall is formed from several rows of such plastic blocks with the blocks in an upper row stacked upon the blocks in an adjacent lower row below the upper row and with the bottom edges of the upper row blocks being supported on adjacent lower row blocks. Decorative facing panels are provided which are substantially smaller in size than the plastic blocks and include a rear face attached to the front face of the plastic blocks to change the outward appearance of the front faces of the plastic blocks. Reinforcing ribs are formed in the walls of the hollow plastic blocks to add strength and rigidity while reducing the amount of plastic needed for the blocks. A keyway and key are formed in the front faces of the blocks and rear faces of the decorative facing panels for securing the decorative facing panels flush against the front faces of the blocks and an adhesive may also be used to attach the facing panels to the blocks. To hold the blocks against shifting laterally, depending tabs on the upper blocks in the retaining wall are inserted into receiving spaces in the underlying blocks on the wall.
