Abstract:
The various embodiments herein provide a prefabricated mineral composite panel and a method for producing the prefabricated mineral composite panel for constructing the internal walls and the lateral walls in a building. The method comprising the steps of: preparing and assembling a cast, fixing a mesh in the cast, pouring a prefabricated mineral composite into the cast, smoothening and flattening a top surface of the cast, disassembling the cast to withdraw a semi- dried prefabricated mineral composite panel, placing the semi-dried prefabricated mineral composite panel in a drying room for drying the prefabricated mineral composite, removing the dried prefabricated mineral composite panel from the drying room and packaging the prefabricated mineral composite panel.
Abstract:
A prefabricated wall assembly for a structure, comprising first and second spaced apart wythes comprising opposing lateral sides of said assembly, a core between said wythes comprising a sheet of rigid insulation having opposed first and second lateral surfaces facing respective ones of the first and second wythes, said core further comprising an array of generally vertical stud channels open to the first lateral surface of the core, and studs located within said channels extending partially across said core. The studs and wythes comprise concrete or other castable material. The studs are integral and continuous with said first wythe to form a monolithic structure. A reinforcement structure may be embedded within the first and optionally the second wythe, with wythe connectors for locking together the respective wythes, reinforcement structures and core.
Abstract:
Hollowcore apparatus for forming a concrete hollowcore slab, comprises a casting bed (1), side wall elements (2) extending longitudinally of the casting bed (1) for defining sides of a casting mould, at least one non-sacrificial inflatable core former (23), at least one, preferably non-sacrificial sleeve (24) for substantially receiving the core former (23), the core former (23) and the sleeve (24) being interconnected and the in use sleeve (24) being turnable inside out by removal of the core former (23) from the casting bed1,and at least one holder (57) for preventing or limiting uplift of the in use inflated core former (23) and sleeve (24) relative to the casting bed (1). A method and hollowcore slab are also provided.
Abstract:
A mold and method of molding where a building panel which is long and hollow typically of plaster is produced, the mold having retractable portions within the mold defining molding surfaces with also a core which are able to be pneumatically positioned and removal of a panel once mold is achieved by lengthwise effort on the pane relative to the mold.
Abstract:
A concrete mould employs resilient side shuttering (2), made of rubber for example, which is prevented from deflecting, when concrete is poured, by tensioning wires (6a, 6b) extending along the length of the shuttering. Pieces of the shuttering, forming the sides of a casting box, extend between fixed end plates (10a, 10b) having a series of holes (8) to receive the tensioning wires (6a, 6b) for adjusting the modular width of panels cast in the box. A series of apertures (4) is provided in each piece of side shuttering (2) so that pneumatic core formers (40) can be inserted through aligned apertures (4) so as to extend across the casting box. Different types of joint formers (42, 43, 44), either fully or partly resilient, can be located about the core formers (40), each joint former having a series of grooves (50, 82, 91) to receive reinforcement or tensioning wires or rods (6, 46). When inflated the pneumatic core former (40) locks the joint formers (42, 43, 44) in place. Opening formers can be made from the shuttering and the joint formers. Standard reinforcement cages (52) can be located in the casting box at modular position corresponding with aligned apertures in the side pieces of shuttering. The modular positions (18) are digitally coded to enable the casting process to be automated by a machine travelling on rails along the length of a casting bed which supports the side shuttering (2) and end plates (10a, 10b). The machine stops at the modular position (18) to locate the respective formers and/or reinforcement cages and it also carries out automatic functions such as cleaning and oiling, laying, packing, screeding and finishing wet concrete.
Abstract:
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.
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:
The present invention relates to a composite panel (10) based on cementitious mortar, passed through its entire thickness by a plurality of through openings (11), each of which is filled with a material transparent to light in the form of a preformed plate (12) housed in said opening (11), or formed in said opening, wherein said cement-based mortar contains at least 30 kg/m 3 of fibres selected from one or more of the following types : metallic fibres, steel fibres, glass fibres, polymeric resin fibres. The invention also relates to methods of production of said panel.

Abstract:
Prefabricated concrete buildings according to a complete building system that gives the possibility to prefabricate the elements (walls, storey slabs) at an industrial site and subsequently to assemble them at their final site assuring the permanent and secure jointing between each other. The building designing method is applied at a grid of s predetermined pitch. Prior to the concrete pouring, at predetermined points on the walls,, metallic fittings are placed at the predicted jointing points. The slabs (19) are fabricated by formworks that carry open holes (15) at corresponding positions with temporary plugs (23); by removing the latter and placing pins (27), holes are formed through which the jointing with the walls (21) takes place with screws (7) or connectors (14). The walls (4), (18), (21) are fabricated by formworks that have holes (15) with centers that coincide with the grid nodes. Sleeve joints (11) and cones are fixed on them and the concrete pouring follows. The advantages of the present invention are the short construction time, the excellent aesthetics of the jointing points and consequently of the whole building, as well as the safe manner of permanent jointing of the building elements at the accurately predetermined points as these come out of the adopted designing methodology.
