A corner form apparatus having a rigid, angled form with a pair of leg sections and a plurality of gussets extending between the leg sections. A post is mounted for axial sliding back-and-forth movement within openings formed in the gussets between a pour position and a stripped position. A linear actuator is mounted between the rigid, angled form and the post and a pair of extension mounting arms are pivotally attached to the post at a first end and pivotally attached to each to an associated form extension using slotted holes at a second end whereupon movement of the post between the pour position and the stripping position moves each of the form extensions from a position coplanar with a corresponding one of the rigid, angled form leg sections in the pour position inwardly to a stripped position.

A connection assembly for formwork elements includes a counterplate, a bolt, and a bolt block. The counterplate can include a plurality of surfaces having differing heights that selectively engage with a waler during engagement or disengagement of the bolt from the formwork element. The formwork element can include a J-shaped waler that allows for easy climbing and/or hanging of objects on a site. The connection assembly can include a bolt block that removably engages a formwork element.

An adjustable concrete footer bulkhead for pouring concrete footers includes a center body; a first slide body and a second slide body each having equal heights; a first rotating concrete pin guide and a second rotating concrete pin guide; a plurality of pins; and a first support bracket and a second support bracket each having a height equal to the height of the first and second slide bodies; and wherein the center body is sized and configured for engaged receipt of the first slide body and the second slide body such that each of the first and second slide bodies are slidably adjustable along the center body, and wherein the first and second slide bodies are each secured to the center body using at least one of the plurality of pins.

A formwork system for supporting forming panels to form a horizontal concrete surface. The system includes a height-adjustable support having a central upstanding member providing a vertical abutment surface and a support arm having an inclined portion extending up and away from said central upstanding member. The system also includes a beam having a transverse bar proximate an end. The transverse bar is supported by the inclined portion of the support arm so that said transverse bar moves laterally relative to the inclined portion as the support arm is moved vertically. The beam also has a foot extending from the end of the beam and abutting the abutment surface. The abutment surface opposes lateral movement of the beam relative to the upstanding member.

A support for installing a porch post comprises a body. The body includes a ground end and a post end opposite of the ground end. A base is disposed on the ground end of the body. Two or more sidewalls extend from the base toward the post end. One or more open cross-members extend between the two or more sidewalls. The ground end may include a ground surface comprising grippers or stanchions extending away from the ground surface for securing the support with the ground.

A formwork element has a theft protection, wherein a base layer is applied onto at least one surface of the formwork element, and wherein at least one signal module for communication with at least one base station is provided. The base layer being designed in a water-tight manner, and an at least partially porous concrete-repellent separating layer is provided above the base layer.

A collapsible structural frame configured to provide a structure to which building material sheets are attached to form a surface. The frame includes a first frame portion that corresponds to a first portion of the surface and is configured to receive a first sheet of the building material and a second frame portion that corresponds to a second portion of the surface and is configured to receive a second sheet of the building material. A pivoting mechanism attaches the second frame portion to the first frame portion and has a pivoting axis. The pivoting mechanism permits the second frame portion to rotate about the pivoting axis relative to the first frame portion from an undeployed state to a deployed state. A locking mechanism may fix a relative position of the first frame portion and the second frame portion in the deployed state.

An adjustable support for use in shuttering formwork comprising a base member, a shuttering contact member, and a bracing member, wherein the base member, the shuttering contact member and the bracing member are engaged hingedly with one another. The bracing member is engaged securably with the shuttering contact member and the base member. The bracing member is adjustable, such that adjustment of the bracing member causes rotation of the shuttering contact member about the base member. Also disclosed is a method for supporting shuttering comprising providing one or more adjustable supports as described above, affixing the or each base member to a substantially static object, assembling the or each bracing member and the or each shuttering contact member as described above, adjusting the or each bracing member and attaching the or each shuttering to the or each shuttering contact member.
