Abstract: A modular layout form has a substantially planar rear for attachment to a support structure, and a substantially planar front having a two-dimensional array of receptacles for holding objects to be embedded in a settable material (e.g., concrete) in a predetermined pattern with staggered courses. The form has substantially straight lateral edges, which results in a pattern of incomplete receptacles along the lateral edges. Object-retention members (e.g., clips, tabs or elastomeric rims) extend into the receptacles for securing objects in the receptacles. Adjacent forms can be combined by abutting their lateral edges with their incomplete receptacles aligned to create completed receptacles. Objects are then inserted into the completed receptacles to engage the object-retention members and hold the adjacent forms together.

Abstract: A modular layout form has a substantially planar rear for attachment to a support structure, and a substantially planar front having a two-dimensional array of receptacles for holding objects to be embedded in a predetermined pattern in a settable material (e.g., concrete). The form includes a plurality of courses staggered with respect to one another to define a pattern of recesses and protrusions at the ends of the courses. Sets of tabs and slots on the recesses and protrusions can be used to engage complementary tabs and slots on the recesses and protrusions of an adjacent form, so that a plurality of forms can be combined by sliding adjacent forms together laterally in a common plane.

Abstract: A corner bracket for holding and securing objects to the surface of a construction form for embedding the object in a settable material, such as concrete, and exposing the face surface of the object in the finished construction, while forming a corner. The corner bracket comprises a plurality of perimeter members corresponding to the outer edge configuration of the object. Removable tabs are incorporated into perimeter members, and may be easily removed. Upon removal of the tabs, the perimeter members may fold around axial points to configure the bracket to fit around a corner. Flanged surfaces, extending inwardly from the perimeter members support the perimeter edges of the objects. Reinforcing crossmembers located subjacent to the fixed axial points on the perimeter members contain channels around which the crossmember and perimeter member may be folded.

Abstract: An individual bracket for holding and securing an object to the surface of a construction form for embedding the object in a settable material, such as concrete, and exposing the face surface of the object in the finished construction. The bracket has an outer configuration formed from a plurality of side and end perimeter members that defines a recess that correspond with the outer configuration of the object. The perimeter members have a flat outer surface extending at right angles to the form and an inwardly extending flange which is parallel and in contact with the form. An upwardly curved inner surface extends from the flange to the outer edge of the flat outer surface which forms one-half of a mold to form a grout line when two brackets are connected together. The actual mold can be any shape desired to provide the various types of grout lines.

Abstract: A disposable object form line for use in horizontal casting of building panels from settable material in which at least one side has an exposed face of embedded objects. The object form liner is comprised of a thin support sheet having an adhesive coating on one side. A closed cell plastic grid having ridges which define openings sized to fit the outer perimeter of the intended objects is provided. The grid is adhered to the adhesive coating on the support sheet. Retarder strips may be inserted in each opening to prevent contamination of the face of the object during the pouring process. The form liner is placed in the bottom of a horizontal mold. The objects, such as bricks, are positioned in the openings provided in the layout form liner and the settable material is poured into the mold to form a construction panel. After setting, the panel and disposable form liner are removed from the mold and the liner is stripped from the panel to expose the objects embedded in the surface.

Abstract: A disposable bracket for holding and securing an object to the inside surface of a construction form for embedding the object and exposing its face surface in a settable material, such as concrete. The bracket has a plurality of perimeter members that corresponds to the outer edge configuration of the object. The perimeter members include an inwardly extending flange which supports the perimeter edge of the object. The bracket perimeter can be closed or open and can have cross reinforcing members, if desired. The cross-section of the perimeter members making up the bracket can include a curved convex outer surface extending upwardly and outwardly from the flange to a flat surface perpendicular to the flange. The perimeter member forms one half of a grout line mold formed in between adjacent objects embedded in the finished wall. The interior of the perimeter member can be hollow to allow flexure between the outer flat surface and the inner flange supporting the object.

Abstract: An object retention form liner is described for use in holding and transferring objects, such as thin bricks to the finished surface of concrete structures. The form liner is produced by strategically positioning a plurality of bricks in a face-up position in a flat, shallow mold. Recesses sized to fit the bricks can be provided in the surface of the mold with a sealing ridge provided between each of the recesses. The bricks are positioned in the recesses and a liquid elastomeric material is poured into the mold to cover the bricks. Reinforcing fiberglass mesh can be embedded in the elastomeric material to provide additional tensile strength to the liner. Upon setting, the liner and retained bricks are removed from the mold and the liner can be stored, shipped or used in concrete construction. The liners are attached to the inside surface of concrete forms and the bricks are held rigidly in place while the concrete is poured and sets.

Abstract: A flexible reinforced concrete form line is provided which includes a plurality of elongated cuttable strips which are sized and embedded within the textured surface of the flexible form liner. The cross-sectional shape of the strips is substantially the same as the cross-sectional shape of the textured surface of the liner except smaller so that the thickness of the elastomeric material making up the liner is substantially constant throughout resulting in consistent expansion and contraction of the liner during setting of the concrete. The strips can be suspended within the liner during the elastomeric molding process or the strips can be directly attached to the plywood form backing sheet prior to the molding process. The total quantity of elastomeric material making up the liner can be greatly reduced which, in turn, reduces the weight of the overall form.

Abstract: A retainer device for holding objects within recesses provided on form liners which are attached to the inside surface of substantially upright concrete structural forms. The retainer device is attached to the form liner to hold the object against the liner so that after the concrete has been poured and set and the forms stripped, the objects will be exposed in the finished surface of the structure. Various retaining devices such as clips having enlarged heads and elongated stems with friction enhancing devices intended to be inserted or attached to the form liner so as to hold the clip in a secure relationship with respect to the objects. Another embodiment of the retainer device is a spring-biased clamp having a body encased within the form liner so that the clamp ends grip the sides of the object. In another embodiment, an elastic band is secured to the form liner ridge provided between recesses.

Abstract: A composite masonary wall structure is formed of inner and outer wall panels stacked and formed on either side of a reinforcing framework formed in a vertical aligned position. Novel cross-tie brackets are provided to secure the upper edges of each panel in proper position equidistant on either side of the reinforcing frame work and tied securely to this framwork. A hardenable or expandable bonding filler material is introduced into the cavity formed between the panels and reinforcing framework structure to bond the panels and framework securely into a homogeneous structure. The cross-tie brackets allow precise positioning of the wall panels with respect to the framework and securely ties the structure together allowing for rapid construction of a composite masonary wall.

Abstract: A flexible surface plywood concrete form liner is disclosed which includes a flat planar sheet of relatively thick plywood material which has been precisely sized and squared. The prepared plywood sheet material is coated with a layer of relatively thin, flexible elastomeric material cast as a one-piece layer over the entire surface of one side of the plywood sheet material as well as all four edges. In this way, the elastomeric material is a continuous integral coating bonded directly to the surfaces of the plywood to prevent the penetration of moisture or chemicals from the concrete into the laminations of the plywood during use. A textured negative impression can be provided on the outer surface of the elastomeric material to leave a textured surface in the finished concrete. A novel edge seal which can be slightly angled is formed along the edges of the liner so that the joint between the liners is reinforced to strengthen and prevent blow-out of the concrete at the liner joints.

Abstract: A novel traveler's head support is provided which includes an elongated relatively wide flexible woven strap having a relatively large loop formed at one end. The end of the loop is provided with a padded section for supporting the forehead of the user and an adjustable length strap attached across the top of the loop to hold the strap in position on the head of the user. The free end of the strap is of a proper length to extend down the back of the user and under an armpit and is wrapped or attached to one of the forearms. An attaching material is positioned on the surfaces of the strap so that the strap will adhere to itself and be held in position on the forearm of the user. Various adjusting and attaching arrangements can be used with the present headrest.

Abstract: An upright mold for forming planar, thin, flexible, elastomeric liners for large modular concrete forms, to produce surface textured concrete walls and the like, includes a positive master of a flexible elastomeric material, secured to a planar, rigid backing, having normal extending, integral gasketing flanges on three sides, a modular form member having a planar surface mounted in the extending flanges, and means for temporarily securing said modular form member in sealing relation to said flanges and with its planar surface spaced a predetermined distance from the master. Liquid polyurethane precursor is poured into the mold form top side permitting trapped air in the liquid to travel to the surface of the modular form member and upwardly out the top of the mold. A small reservoir of the liquid may be maintained at the top of the mold to insure positive pressure of liquid into the mold for the complete filling of the spaces of the mold with the liquid precursor.

Abstract: A lightweight, very strong form of a concrete beam includes a plurality of U-shaped brace members having vertical, lightweight steel deck sheets secured to the uprights thereof, a strippable, non-stick, plastic liner for contacting the concrete of the beam and a rigid foamed plastic filling the space between the liner and the steel sheets, so that it supports the weight of the concrete poured onto the strippable, plastic liner. A column form is arranged to mate with the beam form, and the beam form may be used to mate with flying deck forms producing an integral, combined column, beam and deck structure. The forms are arranged for easily joining short beam sections to make long beam forms, and to join columns and floor decks with a smooth joint requiring no finishing. The strength of the beam forms reduces the quantity of supports necessary to hold the weight of the forms and poured concrete, and their configuration provides easy and quick stripping of the forms from the set concrete.

Abstract: A form assembly for wall-like, large area concrete structures includes a generally planar, rigid panel arranged to abut similar adjacent panels providing a form for the wall-like sructure: a soft, resilient, stretchable plastic liner, mounted on and coextensive with the panel, with at least a complete peripheral seal between edge portions of the panel and the liner, with the liner being secured to the panel in the sealing areas so as to provide a generally airtight, inflatable pouch center-wise of the panel, and gas insertion means for inserting low pressure gas into the inflatable pouch portions for breaking the combined panel and liner from a set concrete structure.
