It should be understood that the face panels of the prior art can be made of any suitable material such as, without limitation thereto, galvanized sheet steel, sheet aluminum and wood or wood compositions such as chip board. Preferably, the face panels of the prior art are made of thermoplastic or thermoset resins. It should be understood that when the panels and/or fasteners of the prior art are made of molded thermoplastic, then recycled thermoplastic can be used to help advance the quality of the environment. - Referring now to
FIG. 3 , therein is shown a perspective view of a preferred “snap-strap” 17 of the prior art molded of a thermoplastic polymer or resin such as, without limitation thereto, a plasticized polyvinyl chloride material or a thermoset resin such as, without limitation thereto, a polyurethane resin. Thestrap 17 comprisesprojections 18 therefrom molded integrally therewith. Theprojections 18 are dimensioned to be an interference fit when pressed through anaperture 12 of aflange 11 of theface panel 10 shown inFIG. 1 .FIG. 4 shows a top view of the snap-strap 17 ofFIG. 3 .FIG. 5 shows a side view of the snap-strap 17 ofFIG. 3 . - Referring now to
FIG. 6 , therein is shown an end view of ahollow block structure 19 assembled when theprojections 18 of the snap-straps 17 are pressed through the apertures of theflanges 11 of theface panels 10. Referring now toFIG. 7 , therein is shown an end view of thehollow block structure 19 ofFIG. 6 from the other end. In use, a number ofblock structures 19 are arrayed in a horizontal course with theside aligning tabs 13 fitted under the adjoining face panel. Then another horizontal course ofblock structures 19 is pressed in staggered fashion above the first course so that locking tabs 15 (also called snap buttons herein) of theface panels 10 engage with the holes oropenings 16 in theupper aligning tabs 14. Then, if desired, additional horizontal courses ofblock structures 19 are laid until the wall or footing form is as high as desired. Reinforcing steel rods can, of course, be inserted as desired as the courses are laid. If larger panels are used, then a wall can be formed from one course of the block structures of the prior art. - Referring again to
FIG. 5 , it will be noted that the preferred shape of theprojections 18 is in the form of a chevron in cross-section. However, it should be understood that other shapes (such as a spheroid) can be used if desired. The outside diameter of theprojections 18 is somewhat larger than inside diameter of theapertures 12 so that theprojections 18 are an interference fit when theprojections 18 are pressed through theapertures 12 to assemble theblock structure 19 ofFIG. 6 . - Referring again to
FIG. 1 , it is preferable to mold fourflanges 11 from theface plate 10 as shown so that half or even quarter blocks can be assembled by sawing theface plate 10 in half or in quarters. Although theblock assembly 19 ofFIGS. 6 and 7 is assembled fromidentical face plates 10, it should be understood that a face plate which is a mirror image of theface plate 10 is preferred so that the side aligning tabs of a block assembly face the same direction. - Referring now to
FIG. 8 , therein is shown a top view of two of theassemblies 19 ofFIGS. 6 and 7 engaged end to end. Closed cell polystyrene foam thermal-insulation panels 20 are then inserted as shown and are highly preferred as providing not only thermal insulation but added strength to the form to withstand the hydraulic pressure of the fluid concrete poured into the form before the fluid concrete cures. And, if larger panels are used, then an insulated wall, insulated with, for example and without limitation thereto, fiberglass or blown-in cellulose insulation, can be formed from one course of the block structures of the prior art even if the wall is not filled with concrete. - The exterior and/or interior of the face panels of the prior art are preferably “finish-faced”. The term “finish-faced” means an external surface not requiring further finishing. Such an external surface could be, for example and without limitation thereto, a stucco type of surface or vertical lines that could-disguise, if desired, the vertical joints of the wall. The face panels can, of course, be molded of a colored thermoplastic or thermoset polymer or resin so that the finished wall does not require painting. The prior art can be used, of course, to make footings, foundation walls and walls above grade.
- An important benefit of the prior art is that by the use of snap-straps of different lengths, walls and the like can be constructed of different thicknesses. The use of relatively long face panels of appropriate design permits the ready adaptation of the prior art to the construction of curved walls.
- Referring now to
FIG. 9 , therein is shown a base-plate system 21 for use with the hollow blocks of the prior art. The base-plate system 21 consists of afront face 22 and arear face 23 connected by snap straps 24 (all of which are preferably injection molded of a thermoplastic or thermoset resin). In use, thebase plate system 21 can be, for example, grouted to a footing. The locking tabs (15 ofFIG. 6 ) of the first course of hollow blocks of the prior art are then located over and pressed into theholes 25 in the front and rear faces 22 and 23. Alternatively, the first course of hollow blocks of the prior art can simply be grouted to the footing. - Referring now to
