The invention relates to a ceiling formwork and a method for producing a ceiling element, comprising the following steps: arranging two ceiling supports on a floor, connecting a first end region of a ceiling formwork frame to the two ceiling supports such that the ceiling formwork frame is arranged in an intermediate position inclined downward from the first end region in the direction of a second end region, connecting a lost ceiling plate to the ceiling formwork frame arranged in the intermediate position, pivoting the second end region of the ceiling formwork frame up, together with the lost ceiling plate, supporting the second end region of the ceiling formwork frame that has been pivoted up by at least one additional ceiling support and casting the ceiling element, together with the lost ceiling plate, on the ceiling formwork frame.

Structural cells and matrices using the structural cells for positioning below a hardscape that define a void space therein, the structural cells, matrices using the cells and methods of assembly allowing in one embodiment the introduction of a structural fluid such as concrete to provide an alternative structural cell and matrix product. In one embodiment a structural cell assembly is described comprising a structural cell with a plurality of legs integrally linked to a frame at a first frame end, the frame linking the legs together and the frame defining a generally flat plane with the legs extending substantially orthogonally away from the first frame end about the frame flat plane to a leg terminal end; and a separate plate engaging the legs, the separate plate comprising linked sockets, each socket engaging the leg terminal end; and/or linked sockets, each socket engaging the leg frame ends or a part thereof.

Apparatus includes construction component. With reference to embodiments as depicted in FIG. 1 to FIG. 30, construction component includes prop-head assembly. Apparatus may be provided for vertically-extending construction column and horizontal construction beam assembly having beam-reference portion. Apparatus includes prop-head assembly configured to be fixedly connected to vertically-extending construction column, and also configured to support horizontal construction beam assembly once the prop-head assembly is fixedly connected to vertically-extending construction column. Prop-head assembly includes first beam-locating feature and second beam-locating feature. First beam-locating feature configured to selectively receive, at least in part, the beam-reference portion. Second beam-locating feature configured to selectively receive, at least in part, the beam-reference portion. Second beam-locating feature is also configured to receive beam-reference portion once the beam-reference portion is inadvertently displaced away from first beam-locating feature and from vertically-extending construction column and toward second beam-locating feature.

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).

The disclosed building construction system with split precast horizontal floor supports combines the strength and ease of construction of pre-cast concrete, with ease of transportation of cast-in-place concrete. The system avoids the requirement of casting difficult shapes by breaking the complex T-shape sections of prior patents into separate flat pieces. The formwork for flat pieces is simpler than that of complex items that include both long and wide components. For examine, T-shapes and cross-shapes are hard to cast and difficult to transport because these shapes do not sit flat, and thus must be supported at their ends. Instead of this complex casting and transport, the slabs are separated into shapes that can later be placed around the columns. This simulates the strength of a fully-precast system, while reducing the precast costs and transportation costs.
