The disclosure relates to formwork for producing a concrete element, in particular a wall element or ceiling element, having an opening, in particular a window opening or door opening, the formwork comprising: a formwork panel; opening formwork, which has a frame element for delimiting a portion of the opening, a support bracket for supporting the frame element, and a mounting element for mounting the support bracket; a formwork-stripping device for transferring the opening formwork from a formwork position for the formation of the opening into a formwork-stripping position for the release of the concrete element, wherein the formwork-stripping device has a sliding and tilting mechanism for sliding the frame element in a direction parallel to the formwork panel and for tilting the frame element about a pivot axis running substantially parallel to the formwork panel.

A concrete mold form (10) is provided to form concrete products such as concrete bridge girder (12). The form (10) has first and second side forms (14, 16) which are supported on carriages (22) riding on tracks (24) for moving the side forms (14, 16) between a closed position to cast the product and an open position to allow the cast product to be removed. At least one of the carriages (22) is a powered carriage (22P, 22M) which rotates a roller (28, 70) engaging the track with a hydraulic motor (38) to move the side form between the closed and open positions.

A module for a paving or building system includes at least one block of concrete and a sheet, e.g., sheet metal, having a surface area abutting the block or blocks. The sheet includes multiple openings and one or more flaps of material from one or more from the openings may be bent or otherwise shaped to extend into a concrete block and anchor the sheet to the concrete block.

A block, block system and method of making a wall block. A block with multiple embodiments of a visually exposed surface having three dimensional shaped areas and three dimensional angular valleys or joints that can be used to construct a patio, wall, fence or the like; the multiple embodiments creating a more random and natural appearance. A mold box having a moveable liner and a stripper shoe that impart three dimensional shaped areas and three dimensional angular valleys or joints onto an exposed surface of a block. The moveable liner and stripper shoe also impart a parting line onto the exposed surface of the block.

A concrete form for holding a concrete product in place during a curing process with at least one side movable by a rotary driven power source and a actuator. A rotary power tool with a helical cutout combinable to a second adapter on the rotary driven power source to rotate the rotary driven power source to power the actuator and move the at least one side.

A switchable magnet device comprising at least one magnet package which can be moved between an interaction position and a release position, wherein the magnet device is configured such that the at least one magnet package, when moving between the interaction position and the release position, at least in portions, performs a pivot movement about a pivot axis. An actuation device is also provided, which can be coupled to the at least one magnet package to move the at least one magnet package between the interaction position and the release position. In order to easily lift the magnet from the formwork support in a small working space, the magnet device is configured such that the at least one actuation device, at least in portions and at least temporarily during the pivot movement of the at least one magnet package, performs a linear movement in a linear movement direction.

A concrete form for holding a concrete product in place during a curing process with at least one side movable by a rotary driven power source and a actuator. A rotary power tool with a helical cutout combinable to a second adapter on the rotary driven power source to rotate the rotary driven power source to power the actuator and move the at least one side.
