Abstract
A concrete block wall panel with mortarless joints in which the blocks are held together by steel strapping and are reinforced by external coatings of glass fiber cement. The walls are handled by pick up rods extending through the panel from top to bottom. A swivel fitting is attached to the upper end of each rod and a pick up base engaging the bottom of the panel is screwed on the lower end of each rod. After the panel is set in a bed of mortar embedding the bases, the pick rods are unscrewed and the swivels are removed.
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 vertically aligned load carrying pillars with vertically aligned openings for vertical lifting rods extending through the pillars from top to bottom, a plate at the lower end of each rod in thrust relation to the pillar surrounding its rod and connected to its rod by a releasable load carrying connection, the blocks having vertical core openings and thrust surfaces within said core openings vertically aligned from top to bottom, 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, one of the loops being a perimeter loop encircling the panel and the other loops being spaced from each other along the length of the panel and having sides of each loop spaced apart a plurality of blocks.
A prefabricated concrete wall panel which may be prefabricated and delivered to a constructon site in modular sizes, siad panel having planar top and bottom load bearing surfaces and laterally spaced top and bottom holes for lifting rods, a plate at the lower end of each rod in thrust relation to and extending below said bottom surface adjacent each rod and laterally spaced from the plate on another rod and connected to each rod by a releasable load carrying connection, the thickness of the plate being the thickness of a mortar joint so that when the panel is lowered onto a bed of mortar on a supporting surface with said bottom surface in load bearing relation to the mortar the excess mortar is squeezed out leaving only a mortar joint of thickness equal to the thickness of the plate.
A concrete block having planar top and bottom surfaces and a first vertical central piller between said surfaces with a vertical opening in the pillar for a lifting rod, a top to bottom core opening between opposite sides of said pillar and each end of the block, and end formations on said block shaped to cooperate with the end formation of another like block when two of said blocks are arranged end to end to provide a second pillar with an opening in alignment with the opening of the first pillar of another of said blocks centered on the joint between said two blocks.
A prefaricated concrete block wall panel, said panel being one block thick, a plurality of blocks high and a plurality of blocks long and consisting essentially of a plurality of contiguous horizontal courses of concrete blocks with the joints between blocks and courses dry and with the blocks in adjacent courses staggered, the individual blocks having vertically aligned load carrying pillars with vertically aligned openings for lifting rods extending through the pillars from top to bottom, a plate at the lower end of each rod in thrust relation to the lower end of the pillar surrounding its rod by a releasable load carrying connection, the blocks having vertical core openings and vertical thrust surfaces within said core openings vertically aligned from top to bottom, a plurality of tension loops at the center of and in the plane of the panel engaging said thrust surfaces for pullng the blocks within the loops tight against each other and putting the blocks in compression both vertically and horizontally, one of said loops being a perimeter loop encircling the panel and the other loops being spaced from each other along the length of the panel and having sides of each loop spaced apart a plurality of blocks.
