摘要:
A building block includes ends having recesses and ribs. Each block end has a recess about ½ the width of a stud in the upper portion so that when blocks are placed end to end they can support a stud. The front and back of the blocks ends have vertical braces or protrusions that form vertical recesses for mortar and a mortar overflow area. The front of the block can have a facade with its ends extending around its front corners.

A method and block for constructing a block wall providing the appearance of a brick facade. Each block includes a front wall, rear wall, left sidewall, and a right side wall. The method includes forming at least one groove on a front face of the front wall of each block or providing blocks with at least one groove on the front face. The method further includes attaching the blocks to each other thereby forming a block structure. The grooves on the front faces of the blocks form a facade and provide an impression that the facade is made of a plurality of bricks.

This invention aims to provide a novel process for making brick-faced block. Colored brick material 11 is laid into a plurality of individual molds 8 of a molding unit 7 to mold at once a plurality of bricks 5 arranged with a predetermined space between each pair of adjacent bricks 5. Then a base block 1 made of foamed resin and coated with a brick adhesive layer 4 is placed and pressed against the molding unit 7 to bond at once these bricks 5 to the brick adhesive layer 4. Thereupon the brick adhesive layer 4 is partially exposed to form joints 6 in accordance with the predetermined space between each pair of adjacent bricks 5. Thereafter, steps of stripping and aging are carried out to form a brick-faced block A.

A method and resulting structural building unit wherein a conventional masonry cement block, for example, has a portion removed, if necessary, to give it a predetermined vertical height. The presized block is placed upon a continuously moving conveyer and one side of the block is preheated and then coated with a liquid material comprising a polyester resin, a styrene monomer, a solvent, and a catalyst. The stored heat in the block quickly evaporates the solvent and polymerizes the resin and monomer so that a strongly adhering bonding coat is formed on the block. A layer of matrix material of relatively thick consistency, comprising a polyester resin, a styrene monomer, finely divided silica, coloidal silica, and a catalyst is applied to the coated block. The layer of matrix may be one-eighth inch thick or thicker, depending upon the type of building unit that is being made. A facing of brick or other material is partially embedded in the matrix, in spaced relation, to form a facing for the block with simulated mortar joints. The non-embedded portions of the facing are exposed to the atmosphere. Sand is sprinkled on the facing material and the exposed matrix. The matrix is then cured or polymerized by passing the block through a curing oven. The matrix permanently bonds the facing material to the block, and renders the covered side of the block impervious to moisture. The sand adheres to the matrix, but is readily removable from the facing materials.
