Abstract:
The aim of the invention is to obtain prefabricated reinforced-concrete modules for a living space that may or may not be divided into compartments, in which the six walls thereof are made as a single piece, which means that the resulting module is 100% monolithic in nature, which cancels out any vibration or expansion and prevents the appearance of cracks or dampness in the module. To that end, six pieces - floor, walls and ceiling - of interior lost shuttering are produced in the factory and joined to one another via the edges thereof using high-strength filler, the lower base having spacer plugs (9) on the floor or the chosen supporting surface, the outer face of the lost shuttering (1, 2, 3, 4, 5 and 6) having the utility installations (11) and, thereon, the insulation material (12), where necessary, followed by a reinforcement (13) and, lastly, recoverable exterior shuttering (14).
Abstract:
This invention relates to modular building construction apparatus and in particular to a mould 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 mould for forming at least one of the inner corner surfaces of a mouldable building module. The inner mould for a mouldable 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 mould facing side wall surfaces movable to a position to form corresponding internal wall surfaces of the mouldable 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 mould. A movable corner arrangement is used to form the internal corners of the mouldable 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 mould facing surface of the corner post is flush with the mould facing surface of respective adjacent movable side walls during the moulding process.
Abstract:
A method is disclosed for producing concrete prefinished parts, in particular tower segments. Concrete is cast in a casting mold having a planar floor to implement a planar bottom side. After the concrete has reached a predetermined minimum strength, an equalization layer is applied to a join surface (110) of the concrete prefinished part (100), which is opposite to the bottom side. As soon as the equalization layer has reached a predetermined minimum strength, the concrete prefinished part (100) is placed on an exactly horizontally oriented surface and the equalization layer on the top side is abraded plane-parallel.
Abstract:
The invention relates to a flange for a self-supporting rigid hollow body having large dimensions and intended for building constructions, to a method for making such a hollow body using such flanges, and to equipment for implementing said method. The rigid flange (6) is intended to be part of a self-supporting rigid hollow body having large dimensions and intended for building constructions, of the type comprising a thin wall (4) having a generally cylindrical shape relative to an axis, made of a coating and resistance material containing concrete or the like and reinforced with fibres, and two such end flanges (6) oriented towards the outside, wherein said flange includes, on the hand, a main portion (9) generally in the shape of a flattened hollow cylinder to be visible in the body upon completion and, on the other hand, a talon (10) extending in an axial direction from a transverse face (11) of the main portion (9) and having inner radial overall dimensions equal to or close to the inner radial overall dimensions of the main portion (9), and outer radial overall dimensions lower than the outer radial overall dimensions of the main portion (9).
Abstract:
The invention relates to a transportable building with a transporting weight of less than 30 t, which can be positioned at the setting-up site on a foundation and in which exterior walls, a roof and floor slab confine a living area closed off from the surroundings. The invention provides a building that is stable and can be better transported over extended distances in that the exterior walls, the roof and the floor slab are formed from weather-proof material, that the exterior walls are of a self-supporting design and that when the building is transported the entire weight of the building weighs on the exterior walls. Furthermore, the invention specifies a method for producing such a building.
Abstract:
An environmental enclosure structure formed of a cement-based slurry infiltrated fiber composite material. The enclosure structure is a box-like enclosure (V) formed of the composite material which is produced by first placing a plurality of individual short fibers or fiber mats of organic or inorganic materials into a form to create a bed of fibers substantially filling the form and having a predetermined fiber volume density and then adding a cement-based slurry mixture includes a composition of Portland cement, fly ash, water, a high-range water reducer (superplasticizer), and may also include fine grain sand, chemical admixtures, and other additives. Due to its fiber volume density and method of manufacture, the resulting structure has thinner walls (10, 11), greater strength, and a gross weight significantly less than conventional reinforced and pre-stressed concrete structures of the same size, and a much higher bending capacity approximating that of structural steel.
