Licht leitendes Bauteil, insbesondere Betonfertigteil in Form eines Mauersteins, für Bauwerke und Gebäude, wobei das Bauteil in einer Gussform (29) durch Eingießen in mindestens einen Gussbaustoff (19) hergestellt ist und wobei der Lichtleitkörper (1) aus einem Licht leitenden Baustoff, z.B. PMMA-Kunststoff oder Glas, ausgebildet ist, der mindestens an zwei Positionen auf der Außenfläche des Licht leitendes Bauteils für die Lichteinkopplung (8) und Lichtauskopplung (9) zugänglich ist, wobei der Lichtleitkörper (1) als selbsttragender 2D- oder 3D-Gitterkörper (1) aus Stäben (2, 3) mit Dicke/Durchmesser größer 1 mm ausgebildet ist, wobei der selbsttragende 2D- oder 3D-Gitterkörper (1) etwa gleiche oder nur geringfügig kleinere Breite (B), oder Länge (L), oder Grundrissmaße (B, L), oder Gesamtaußenmaße (B, L, H) hat, als die Gussform (29) selbst. Aufgabe der vorliegenden Erfindung ist es daher, ein Bauteil insbesondere Betonfertigteil in Form eines Mauersteins für Bauwerke und Gebäude derart weiterzubilden, dass dieses wesentlich schneller und kostengünstiger hergestellt werden kann.
摘要:
Method for coating a mechanical member (10) provided with at least a support plate (1 1) and one or more tubular elements (12) attached in through manner to the support plate (11). The method comprises a first coating step, in which an external surface (15) of the support plate (11) is coated with a first layer (16) of plastic material, and a second coating step in which a terminal portion of the internal surface (17) of the tubular elements is coated with a multi-layer coating (19). In the second coating step the multi-layer coating (19) is made by depositing in sequence one on top of the other a plurality of layers of plastic material (19a, 19b, 19c), each of which is deposited partly in correspondence with the terminal portion of the internal surface (17) of the relative tubular element and partly in correspondence with the surface of the first layer (16) of the external surface (15) of the support plate (11).
摘要:
A method for fabricating an acoustic metamaterial may include providing a planar pattern of springs arranged in columns and rows and separated from each other by interconnection nodes, providing a planar pattern of mass units separated from each other by a distance corresponding to a distance between the interconnection nodes, providing an array of vertically oriented springs separated from each other by the distance between the interconnection nodes, and aligning and joining the planar pattern of springs, the planar pattern of mass units and the array of vertically oriented springs to form a layer of unit cells.
