Abstract:
The invention relates to a method for making a profile for supporting ceiling plates and the like, which profile shows a continuous fixation strip, a body and wings upon which the plates or the like rest, characterised in that to form the body of the profile, it is started from at least one metal band wherein in series of incision are applied in the longitudinal, respectively transversal direction, whereafter the metal band is pulled in the transversal, respectively the longitudinal direction, to an open structure (7, 7').
Abstract:
The invention relates to a truss bracing concrete or masoned structural layers together and to a method for manufacturing the truss. The truss is used e.g. in a thermally insulated prefabricated element for binding inner and outer element layers (1, 2) to each other through an insulation (3). The truss is manufactured from a blank sheet, which is provided with slits and the blank is stretched in a direction perpendicular to the slits. The slits are disposed and arranged to develop, after stretching of the blank, substantially parallel chords (5) and diagonal braces (6) therebetween, the latter being stretched during the stretching operation.
Abstract:
A method and apparatus for manufacturing expanded metal mesh wherein a longitudinally ribbed metal strip (13) passes through a series of straightening rollers (17) to a slitting (or slotting) means (21) whereby rows of transversely spaced longitudinally running slits (or slots) (46) are provided between the ribs (14) of the strip (13). Driving rollers (19) cooperate with tensioning rollers (39 and 40) to pass the strip (13) to an expansion assembly (41) having die plates (42) which carry guide slots (43) that receive the ribs (14) relatively displacing them to form expanded metal mesh (11).
Abstract:
A machine for expanding a precut or slotted workpiece (30) having a plurality of ribs (31) spaced apart by web portions (32), includes a table (12), expanding means comprising a cross-bar (17) carrying claws (20) and mounting plates (25) fixed in relation to the table (12) with a movable cross-bar (18) carrying claws (21) and mounting plates (26) actuated for movement across the table (12) by driven sprocket (14), chain (15) and idler sprocket (16). Connected to mounting plates (25, 26) is a linkage means (24) upon which are located expander bars (27) adapted to engage selected ribs (31) of the workpiece (30) whereupon actuation of the chain drive (14, 15, 16) will move the linkage means (24) and the expander bars (27) from an initial position in which the expander bars (27) are close enough together to enable the workpiece (30) to be located on the table (12) with the expander bars (27) positioned between adjacent ribs (31) of the workpiece (30) to a final position to which the expander bars (27) have moved, thus expanding the workpiece (30) to a predetermined extent.
Abstract:
Es wird ein Bauprofil, insbesondere ein T-, C-, U-, V-, H-, L-, M-, W-, Q- oder Hutprofil, mit einem insbesondere metallischen, lang gestreckten Grundkörper (14) beschrieben. Der Grundkörper umfasst einen sich in Längsrichtung erstreckenden, im Wesentlichen geschlossen ausgebildeten Mittelbereich (15) und zumindest zwei sich beidseits des Mittelbereichs (15) erstreckende Längsbereiche (16). In den Längsbereichen (16) sind quer zur Längserstreckung des Grundkörpers (14) aufgeweitete Öffnungen (13) angeordnet. Im Mittelbereich (15) des Grundkörpers (14) ist eine sich in Längsrichtung des Grundkörpers (14) über dessen gesamte Länge erstreckende Profilvertiefung (18) oder -erhöhung mit seitlichen Führungsflächen (19) ausgebildet. Weiterhin werden ein Verfahren sowie eine Vorrichtung zum Herstellen eines solchen Bauprofils beschrieben.
Abstract:
The invention provides a method for manufacturing an inner pressure deformed sheet metal structure comprising at least one step of applying an inner pressure to at least one cavity of a pre-structure. The cavity is formed from one plate of sheet metal and comprises at least three fixed edges. Also provided is a pre-structure being formed from one plate of sheet metal and comprising at least one cavity, wherein the cavity comprises at least three fixed edges or provided by the method of the invention. And an inner pressure deformed sheet metal structure manufactured by the method of the invention and uses in construction thereof. The invention also provides triangular frames characterized in that one inner pressure deformed sheet metal structure is in triangular configuration or in that at least three inner pressure deformed sheet metal structures are assembled in triangular configuration.
Abstract:
The invention relates to honeycomb material for the production of honeycomb panels. According to the invention, the honeycomb material comprises metal strips, which strips are each provided, on at least one side, with a layer of thermoplastic material and have a continuous, substantially trapezoidal shape, the thermoplastic material being responsible for bonding the metal strips to one another. The invention also relates to methods for producing this honeycomb material.
Abstract:
The invention relates to a method for manufacturing a flat or three-dimensional lattice structure. The structure comprises at least two booms (3), made of a sheet-like material and tied together with diagonal braces (4). The sheet material of a bank (1) extending between the booms is cut to provide it with slits (2) substantially parallel to the booms (3) and the booms are distanced from each other, whereby the sections between the slits (2) turn and stretch into the diagonal braces (4) connecting the booms (3).
Abstract:
