Abstract
A concrete block panel with mortarless joints in which the blocks are held together in vertical and horizontal compression by steel strapping and are reenforced by external coatings of glass fiber cement. The blocks may be insulated by urethane foam board sandwiched between the outer surface of the panel and external facing blocks. The blocks may also be used with mortar joints. The urethane foam board insulation assists in laying the blocks with either dry or mortar joints.
Claims13
A prefabricated concrete block wall panel, said panel being one block thick, a plurality of blocks high and a plurality of blocks long and comprising a plurality of contiguous courses of concrete blocks with the joints between the blocks and courses dry and with the joints between blocks in adjacent courses staggered, the blocks having spaced load carrying walls with planar top and bottom load carrying surfaces and vertically aligned load carrying pillars at the centers of the blocks, the blocks having vertical core openings and thrust surfaces on said pillars within said core openings vertically aligned from top to bottom, said thrust surfaces being parallel to each other and having edges spaced inward from said walls, a plurality of tension loops at the center of the panel each surrounding a plurality of blocks both vertically and horizontally and each engaging said thrust surfaces for pulling the blocks within the loops tight against each other both vertically and horizontally and putting the blocks in compression both vertically and horizontally, the loops being spaced from each other along the length of the panel and having sides of each loop spaced apart a plurality of blocks, and struts diverging from opposite edges of said thrust receiving surfaces to said walls for transmitting load from tension loops on said thrust receiving surfaces in compression through the pillar to said walls.
A concrete block having spaced load carrying walls with planar top and bottom load carrying surfaces, a vertical load carrying pillar between said walls, a top to bottom core opening between opposite sides of the pillar and each end of the block, vertical thrust receiving surfaces at the center of the block and on each of said opposite sides of the pillar for tension straps extending through said core openings for pulling the block horizontally toward an adjacent block, said thrust receiving surfaces being parallel to each other and having edges spaced inward from said walls, and struts diverging from opposite edges of said thrust receiving surfaces to said walls for transmitting load from tension straps on said thrust receiving surfaces in compression through the pillar to said walls, a facing block spaced from the outer surface of one of said walls and a block of insulating material sandwiched between and adhered to said block and said outer surface of said one wall.
A prefabricated concrete block wall panel, said panel being one block thick, a plurality of blocks high and a plurality of blocks long and comprising a plurality of contiguous courses of concrete blocks with the joints between blocks and courses dry and with the joints between blocks in adjacent courses staggered, and means for putting all of said blocks in compression both horizontally and vertically, said panel further having facing means spaced from one surface of said panel, and insulating material sandwiched between and adhered to said one surface and to said facing means.
