A concrete form system includes a plurality of concrete form board brackets. The plurality of brackets includes brackets for securing the concrete form board to a conventional type metal or wood concrete form stake without the need for nails. The plurality of brackets also includes concrete form board end brackets for securing the ends of adjacent concrete form boards together that allows for a range of angles to be formed between two adjacent concrete form boards from zero degrees to more than 180 degrees. The present invention also includes flexible sections of concrete forms configured to be coupled to the brackets that allow for forming curved concrete edges.

A formwork apparatus defining a formwork space for forming a slab is disclosed. The apparatus comprises at least one lower formwork member and at least one upper formwork member and a plurality of formwork brackets. Each formwork bracket has a connection arrangement for operatively connecting the bracket to the lower and upper formwork members. The formwork brackets are configured to space the upper and lower formwork members a certain distance apart from each other along their length such that the formwork members extend parallel to each other. An apparatus for positioning an anchor for a construction member such as a reinforcing rod in a slab when it is cast is also disclosed.

A formwork panel system comprising corner connectors comprising a first body portion and a second body portion forming a 90? angle, at least one opening in the first body portion, a first prong extending from the first body portion, and a second prong extending from the second body portion, wherein the corner connectors and side rails form a rigid body connected to a first panel. The panel system where the at least one opening secures the corner connector to a corner connector of a second panel via a bolt and rectangular nut member. The panel system further comprising plurality of fasteners configured to be inserted into prong openings wherein the plurality of fasteners are configured to compress the side rails about the prongs.

A building form system including a plurality of forms for assembling into a wall template that is filled with concrete to create a building wall. The system includes a corner form assembly comprising an inner corner form and an outer corner form for disposition on a corner footing. The outer corner form includes walls angled from a bend. A pair of connectors are disposed on opposite ends from the bend. The inner corner form includes corresponding connectors for attachment to the outer corner form around a preset vertical rebar in the corner footing. The system further includes a base form extending between a first pair of connectors that include a peripheral wall disposed directly therebetween and the second pair of connectors for mating engagement with the first that include an inset wall spaced inwardly therefrom. Spacing between the peripheral and inset wall of adjacent base forms accommodating vertical rebar.

A stay-in-place footing form assembly includes a plurality of inner form boards serially aligned and joined by inner joining brackets, a plurality of outer form boards serially aligned and joined by outer joining brackets, a plurality of lower spacing rails, each disposed between and connecting base brackets in the inner and outer joining brackets aligned laterally, and a plurality of upper spacing rails, each disposed between and connecting top brackets in the inner and outer joining brackets aligned laterally. The lower spacing rails include first rebar receptacle(s) for seating horizontal rebars on the rails, and the upper spacing rails include second rebar receptacle(s) for holding vertical dowel rebars therein. The inner and outer form boards are insulation boards that have an ability of absorbing lateral forces of earthquakes exerted to a concrete footing formed in the stay-in-place footing form, and an ability of insulating the concrete footing from surrounding temperatures.

A stay-in-place form comprises a plurality of elongated panels connectable to one another in edge-to-edge relationship. The plurality of panels comprises first and second panels connectable to one another in edge-adjacent relationship by a connection which comprises a contact joint. The first panel comprise a longitudinally extending first seal-retaining projection shaped to project outwardly from the outer surface of the first panel at a location spaced apart from a first outer-surface transverse edge of the first panel in a first transverse direction. The second panel comprising a longitudinally extending second seal-retaining projection shaped to project outwardly from the outer surface of the second panel at a location spaced apart from a second outer-surface transverse edge of the second panel in a second transverse direction opposite the first transverse direction. The first and second seal-retaining projections and the outer surfaces of the first and second panels defining at least a portion of a seal-receiving concavity which opens outwardly from the form when the connection is made.

A stripping corner for an inside form, such as for forming the inside corner of an elevator core in building construction for pouring concrete, is provided that includes a powered actuator that forcibly collapses the perimeter of the inside form, particularly the inside corners of the form, to allow displacement of the inside form from the formed concrete surface to strip the inside form from the concrete.

A set of extruded profiles for the construction of slabs, beams and columns, which are assembled in a systematic manner and have the function of covering the slab, column and beam, eliminating the need for any finishing, and has the function of serving as to receive the concrete during construction. The constructive arrangement of the parts forming said set of profiles and allowing their assembly in a systematic manner, guarantees numerous functional advantages, as well as in their use and is comprised of five extrusion profiles, preferably PVC, not limited to this material, comprising a main plate, a filling profile, which will replace the Styrofoam block, and three profile variations for column construction.
