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 configurable steel form system for creating precast concrete panels is disclosed. The configurable steel form system can be used to create precast panels for both commercial tilt panels and highway noise barrier walls, among other applications. A plurality of steel form system sections are preferably fabricated from steel plate bent into a J-channel member. The configurable steel form system can be designed in sections that are quickly assembled. To suit a particular application, a section can be extended by sequentially attaching extension members to a primary member. A quick-release mechanism can be implemented for ease and speed of connection. Each section can have the panel depth and contour fabricated into the steel form profile. Anchoring holes and corner miters can also be cut into the form's framework.

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 system, comprising: at least one planar member having a two- or three-dimensional surface pattern formed thereon or therein; and a plurality of resilient spacers removably positionable on or in the surface pattern to form a surface relief pattern of spaced-apart recesses on the at least one planar member.

A method for adjusting a sidewall unit (1) of a casting mold for concrete products, which sidewall unit comprises a support structure (2, 32, 42) and a mold surface plate (3, 3′, 33, 43) fixed to the support structure, and which sidewall unit is fixed on a casting bed (8), wherein the mold surface plate comprises at least two portions (3, 3′) extending along the length of the sidewall unit and connected to the support structure (2) and the vertical position of at least one of the portions (3), defined by orientation of the sidewall unit (1) fixed on a casting bed (8), is adjusted to form a gap (9) extending along the length of the sidewall unit between the portions. The invention also relates to such a sidewall unit.

A magnetic coupler having a housing defining a coupler plane, a magnet assembly positioned at least partially within the housing, the magnet assembly being movable relative to the coupler plane, and a release assembly coupled to the magnet assembly to selectively reposition the magnet assembly relative to the coupler plane based on the angular orientation of the release assembly.

Switchable magnet device, comprising: at least one magnet stack that is transferable between an interaction position in which the magnet stack is magnetically functionally connected to the formwork support, preferably to a magnetisable formwork support, preferably by contact with the formwork support, and a release position in which the magnetic functional connection between the formwork support and the magnet stack is reduced, preferably canceled. For simple lifting of the magnet device, the magnet device furthermore comprises a fluid-driven energy transmission mechanism that is coupled to the at least one magnet stack in order to transmit a force to the at least one magnet stack for at least partially transferring the at least one magnet stack from the interaction position into the release position.

A configurable form system for creating precast concrete panels is disclosed. The configurable form system can be used to create precast panels for both commercial tilt panels and highway noise barrier walls, among other applications. A plurality of form system sections are preferably fabricated from steel plate bent into a J-channel member. The configurable form system can be designed in sections that are quickly assembled. To suit a particular application, a section can be extended by sequentially attaching extension members to a primary member. A plurality or faces or shoring apparatuses can be coupled to the section to circumscribe or form an inner diameter of an enclosure formed by the sections. The shoring apparatuses can vary in height, allowing for fabrication of panels of variable thickness using the same forms or framework. The shoring apparatuses can be configured to removably engage ends of sections to facilitate the formation of enclosures using the sections.
