Disclosed herein is an article of manufacture that increases the efficiency of forming a building material having a keyed joint with a waterstop imbedded within the building material. The article allows the easy formation of a keyed joint between formed solid slabs (typically concrete) with a waterstop properly imbedded between the slabs.

A forming system includes a frame and two forming walls. The two forming walls are positioned at a distance from each other to define a first vertical wall course. One forming wall is supported by the frame such that the one forming wall can be translated toward or away from the respective other forming wall. The frame can be raised to raise the two forming walls to be positioned to pour a second vertical course on top of the first vertical course. The translation of the one forming wall allows for the pouring of the first vertical course with horizontally extending rebar that extends through the one forming wall outside of the first vertical wall course, to tie in to a subsequently poured floor slab. The translation permits the vertical raising of the one forming wall, without striking the extending rebar, to pour the second vertical course on the first vertical course. A worker's platform is provided that is supported by the frame and vertically movable by raising the frame. The worker's platform is located below the one forming wall on a side of the one forming wall opposite the respective other forming wall and is rollable or pivotal to also clear the extending rebar during raising of the frame.

The invention relates to a support (1) for supporting a structure region, comprising a central part which has a hollow profiled rectangular tube (8) and two end parts (4), wherein each of the end parts (4) is arranged so as to be telescopable out of the central part from open ends (9) of the hollow profiled rectangular tube (8) in order to change the length of the support (1). Each of the end parts (4) has a hollow profiled round tube (2, 3), and inner wall regions (21) of the hollow profiled rectangular tube (8) form guides for the hollow profiled round tubes (2, 3). The hollow profiled round tubes (2, 3) can be guided in the central part in the longitudinal direction of the hollow profiled rectangular tube (8) by means of contact region (22) lying against the guides so as to achieve the telescopability of the end parts (4).

A formwork apparatus for producing a wall section in fresh concrete design that includes projecting connection reinforcement elements for connecting a floor to be constructed, comprising a formwork element that includes a support structure and a forming panel supported on the support structure. The formwork element is provided on one of its edge sections with a plurality of edge recesses spaced preferably uniformly apart from one another for the connection reinforcement elements. A single forming board element or multiple forming board elements serve to reversibly cover the edge recesses when the connection reinforcement elements extend through the edge recesses. A method for producing wall sections situated vertically above one another with projecting connection reinforcement elements in fresh concrete design for connecting to a floor.

Disclosed herein is a clamp for interconnecting two components of a support apparatus such as components of a shoring apparatus for concrete forming systems. A clamp member having a moveable jaw is received for pivotal movement in a housing that is secured to one of the components. A plurality of flutes disposed at an angle to the pivot axis of the clamp member are received in coacting recesses in the housing and a proximal cap maintains the desired position of the clamp member within the housing. Axial movement of the clamp member will pivot the swing arm and a coacting, moveable jaw toward a fixed jaw formed in the housing to releasably secure the clamp to the other component.

The invention relates to a corner shuttering element with two limbs (12, 14) arranged at an angle to each other, on the outer edge of which limbs (12, 14), edge strips (16, 18) are arranged that can be retracted and extended by means of articulated levers (24, 26), wherein the edge strips (16, 18) can each be aligned and fixed in their position by means of a plurality of locking elements (34) arranged distributed over the height of the corner shuttering element, and wherein the locking elements (34) are arranged on guides (32) for pull-out webs (30) of the edge strips (16, 18).

An independent self-climbing form system may be assembled at a work site to build, maintain, or repair vertical structures. The independent self-climbing form system may include a plurality of support towers. Additionally, at least two trusses may be connected to the plurality of support towers. The trusses may be spaced apart from each other. Further, one or more platforms may be formed within a perimeter delimited by the at least two trusses. The at least one or more platforms may be configured to extend or retract within the perimeter. Furthermore, screw jacks may be disposed at each connection point of the at least two trusses on the plurality of support towers. The screw jacks may be configured to vertically move the at least two trusses up and down the plurality of support towers.

An upright concrete wall panel form apparatus includes a back panel form to be secured to a base in an upright position, an adjustable support assembly to be secured to the base adjacent the back panel form, and a movable front panel form supported by the adjustable support assembly in an upright position. The movable front panel form is moveable via the adjustable support assembly between a concrete wall panel prep area position and a concrete wall panel forming position. The movable front panel form is aligned with the back panel form in the concrete wall panel forming position so as to define a gap therebetween to receive concrete for forming at least one concrete wall panel in an upright position.
