The invention relates to an apparatus for the one-piece production of a room module (8) having three side elements (24) and a floor element (25) and/or a ceiling element (26), wherein the apparatus takes the form of a parallelepipedal and hollow core formwork (10) around which an outer formwork (9) for the room module (8) to be produced can be arranged. The following are provided here: a) a rectangular head element (11) which consists of first planar elements (1) and second planar elements (2), b) side elements (12, 13, 14, 15) which consist of a third planar elements (3) and fourth planar elements (4) and are arranged perpendicular to the head element (11) in the edge regions thereof, wherein at least the third planar elements (3) or the fourth planar elements (4) have corner regions (17) of the side elements (12, 13, 14, 15), c) the first planar elements (1) can be lowered under the second planar elements (2) of the head element (11) and can be displaced with respect to one another and, subsequently, the second planar elements (2) can be pushed together with a reduction of the rectangular area of the head element (11), and d) the third planar elements (3) and fourth planar elements (4), which are arranged perpendicular to the head element (11), of the side elements (12, 13, 14, 15) can then be moved in succession in the direction of a centre longitudinal axis (16) of the head element (11) or the core formwork (10).

This invention relates to modular building construction apparatus and in particular to a mold having movable framework used to construct a basic building module where any miss-alignment at the junction of framework elements is enough to make the imperfection noticeable. If the imperfection is a ridge it will be readily apparent on the inside surface of the formed building module and it will not be disguised by painting over it. What is disclosed is a movable corner arrangement for a mold for forming at least one of the inner corner surfaces of a moldable building module. The inner mold for a moldable building module has an upper support panel for forming the ceiling surface of the building module and a plurality of movable side walls that depend from the upper support panel using flexible peripheral edge elements. The side walls have mold facing side wall surfaces movable to a position to form corresponding internal wall surfaces of the moldable building module. The movable side walls are movable inwards and away from their respective formed internal wall surfaces to release the formed building module from the inner mold. A movable corner arrangement is used to form the internal corners of the moldable building module located between adjacent movable side walls. The movable corner arrangement includes a corner post having at least one side wall abutment surface; a corner post support coupling adapted to adjust the vertical and sideways position of, and verticality of the corner post with respect to the desired position of adjacent movable side walls such that the mold facing surface of the corner post is flush with the mold facing surface of respective adjacent movable side walls during the molding process.

An apparatus and method for precision forming a precast concrete flight of stairs is disclosed and where precision cut form components provide plural tread supports, plural sideboards, plural tread/riser combinations and a center tread support that upon assembly, the form components, automatically square and align treads and risers with upper and lower landings for installation to provide access between vertically spaced apart floors of a structure.

Disclosed are various construction techniques for erecting a multistory building with an elevator shaft. In accordance with the method, upper and lower shaft components are formed at an offsite facility. These shaft components are then joined together to form a segment of the larger elevator shaft. Once constructed, the segment is transported to a jobsite and erected. Once an individual segment is installed, a floor slab can be formed about the segment. Using pre-cast elevator segments simplifies and expedites the construction process. In one embodiment, each segment includes a serrated edge that facilitates a connection between the floor slab and the shaft segment. Rebar and reinforcing dowels can also be used to improve the connection. Associated shaft constructions are also disclosed.
