This invention relates to the masonry veneer form liner used with a concrete/cementitious material flow-through grid forming panel during a concrete/cementitious pour.
Conventional, concrete forms consist of plywood or wooded and metal panels temporarily maintained in spaced apart and parallel relationship by means of ties. The concrete in poured between these forms which are then stripped away after the concrete has set up. These panels can be expensive and awkward to manufacture, store, and ship.
Alternatively and more recently forms such as insulated concrete forms with foamed plastic panel that becomes part of the poured wall or structure have gained acceptance in the construction industry. Some difficulties have developed in some applications due to the outside of the panel being made of foam plastic which include; penetrability of the foamed plastic, insect entrance questions, waterproofing difficulties, the stigma of previous stucco (EIFS) application failures and the question of fire ratings.
In McCary, U. S. 2010/0051779, now U.S. Pat. No. 8,153,046, discloses a method of assembling a plurality of modular forming units to create a freestanding structure, wherein each unit consists of a least one lattice or grid framework panel having a plurality of openings there through and another spaced apart forming panel to create a forming cavity.
Concrete/cementitious flowable material is introduced into the cavity, wherein the concrete/cementitious flowable material fills the cavity and flows non-restrictively through the lattice framework panel(s) such that the cementitious material extends beyond the external surface of the lattice framework or grid panel(s) creating an external surface layer; and then allowing the material to set and become a monolithic structure. McCary had described the attachment of stencils and form liners to the exterior face of the concrete/cementitious grid flow-through forming panel but had not addresses the attaching of masonry veneers, such as thin brick, to the exterior face of the grid form panel before the concrete/cementitious pouring into the cavity of the concrete/cementitious form.
Various patents were issued to masonry veneer style holding forms, including Goldman, U.S. Pat. No. 4,858,410 Aug. 22, 1989, where masonry veneer could be placed in horizontally placed holding forms with the face or to be exposed side of the masonry veneer facing down. Then concrete/cementitious material would be poured upon the masonry veneer and holding form. When the concrete/cementitious material had dried sufficiently then the masonry veneer holding form would be pulled off exposing the face of the masonry veneer and the concrete/cementitious poured material now representing the mortar joint between the masonry veneers.
Vertical applications were introduced of holding masonry veneers in a vertical holding form or bracket, as in Scott, U.S. Pat. No. 5,667,190 Sep. 16, 1997, later in Scott, U.S. Design Pat. No. D625,846 Oct. 19, 2010, in Marshall, U.S. Pat. No. 6,360,505 and in Williams, U.S. Pat. No. 6,360,505, Mar. 26, 2002. In Scott, Marshal and Williams, masonry veneers holding forms are attached on the interior face of a vertical concrete/cementitious forming panels and masonry veneers placed in the masonry veneer holding forms before the concrete/cementitious pour into the forming cavity. After the concrete/cementitious material is poured and allowed to harden to the desired stiffness the forming panels are removed along with the masonry veneer holding forms, exposing the face of the masonry veneer and the concrete/cementitious poured material now representing the mortar joint between the masonry veneers.
The present invention is a masonry veneer holding form liner that attaches to the exterior face of a concrete/cementitious grid flow-through forming panel. The grid form masonry veneer holding form liner is primarily in pattern shapes of the mortar joints surrounding an assembly of masonry veneers such as bricks, thin bricks, stone, thin stone, block or thin block. There are periodically spaced holding or catch points on the circumference of the mortar joint pattern. The masonry veneer holding form liner is attached to the concrete/cementitious flow-through grid form usually by screws and bolts that protrude through periodic holes in the grid form mortar shaped masonry veneer holding form liner. The attaching screws or bolts either then have grapple style catches then attached to the attaching ends of the screws or bolts or the screws or bolts without grapple catch first attached are pushed through the concrete/cementitious grid form grid openings and then a grapple style catch, wing nut style catch or other catch that holds the mortar joint patterned masonry veneer holding form liner on the exterior face of the concrete/cementitious flow-through grid forming panel. Masonry veneers, usually thin bricks, thin blocks, tiles or pavers can then be placed into the masonry veneer holding form liner spaces between the mortar joint pattern masonry veneers holding form liner. Either periodically placed catches on the circumference of the holding form liner masonry veneer holding spaces or friction of the mortar joint pattern holding form hold the placed masonry veneers in place during a concrete/cementitious pour. When concrete/cementitious material is poured into the vertical or horizontal (as in pavers, tiles) oriented forming cavity with the masonry holding form liner attached to the concrete/cementitious flow-through grid forming panel(s) the concrete/cementitious material flows through the grid openings of the grid forming panel's grid openings up to the interior or non-exposed face of the masonry veneer and up to the interior side of the masonry veneer holding form liner. After the concrete/cementitious material is allowed to harden to the desired stiffness the masonry veneer holding forms are unscrewed or unbolted from the concrete/cementitious embedded grapple, wing nut or other style holding catch and masonry veneer mortar joint pattern holding form liner is released from the exterior of the grid form, exposing the face of the masonry veneer and the concrete/cementitious poured material now representing the mortar joint between the masonry veneers. Alternatively, the concrete/cementitious poured material now representing the mortar joint between the masonry veneer can be so narrow that all or a portion of the masonry veneers have the appearance of dry stacked, having no mortar joint, or very narrow mortar joint.
