Verfahren zur Herstellung eines aushärtbaren Lichtleitkörpers (21) im Gießverfahren, insbesondere zur Herstellung von Lichtleitkörpern (21) aus einem aushärtbaren Betonwerkstoff (36, 56), wobei eine Lichtleitermatte (1) in einer aushärtbaren Giessmasse (36, 56) eingebettet wird, und eine Gießform (27) mit einer vertieften und nach oben offenen Gussausnehmung (18) mit der noch nicht ausgehärteten Giessmasse (36, 56) befüllt wird, wobei in einem ersten Verfahrensschritt eine Mehrzahl von in der Gussausnehmung (18) der Gießform (27) verschiebbar angeordneten Formstempel (32) bis auf mindestens die Ebene der Oberkante (43) der Gussausnehmung (18) vorgeschoben werden, 1. dass in einem zweiten Verfahrensschritt der Zwischenraum zwischen den Formstempeln (32) in der Gussausnehmung (18) mit einer aushärtbaren Giessmasse (36) aufgefüllt wird, 2. dass in einem fünften Verfahrensschritt die in der Giessmasse (36, 56) einzubettende Lichtleitermatte (1) auf die Stirnseiten (61) der in der Gussausnehmung (18) angehobenen Formstempei (32) aufgesetzt wird, 3. und dass in einem sechsten Verfahrensschritt die Lichtleitermatte (1) in die Giessmasse (36, 56) eingepresst wird, wobei mit der Einpressbewegung der Lichtleitermatte (1) in die Giessmasse (36, 56) die Formstempel (32) annähernd synchron nach unten aus der Bodenfläche der Gussausnehmung (18) heraus gefahren werden.
摘要:
Method for making a composite panel comprising a pourable and settable base material, preferably cementitious mortar, and a plurality of through elements (10) made of glass for transmitting light between two base surfaces (1.1') of the panel (1). The method includes making a semi-finished product comprising a central body (50) which incorporates the through elements (10), which emerge from two mutually opposite main surfaces (51, 52). In particular, the method includes making the semi-finished product by defining two containing frames, mutually opposite with respect to the body, each of which emerges from one of the central surfaces. The method includes closing the semi-finished product between two containing elements so as to define two half spaces. each of which at least partially delimited by said containing frames. The method then includes filling each half-space with cementitious mortar and removing the manufactured item which is made, after the mortar has set. Finally, the method includes finishing such a manufactured item by eliminating the containing frames from the semi-linished product, the body of which remains incorporated in the structure of the panel.
摘要:
A glazing assembly is disclosed, the assembly comprising first and second toughened glass members. Each member comprises a sheet with first and second flanges projecting from opposite ends of the sheet in a direction substantially perpendicular to the sheet, and the first and second flanges of the first member are joined respectively to the first and second flanges of the second member by first and second connector portions such that the first and second flanges of the first member are substantially coplanar with the first and second flanges of the second member, respectively. A modular glazing array is also disclosed. The array comprises a plurality of glazing assemblies arranged side by side, such that at least one pair of joined, coplanar flanges of each of the plurality of glazing assemblies faces a pair of joined, coplanar flanges of another of the plurality of glazing assemblies.

In one embodiment, a multiwall sheet can comprise: a first wall; a second wall; an intermediate wall disposed between the first wall and the second wall; a first set of ribs disposed between the first wall and the intermediate wall; a second set of ribs disposed between the second wall and the intermediate wall; a cavity disposed between adjacent ribs; wherein the multiwall sheet is configured to expand and/or collapse when a mechanical force (preferably shear force) is applied to the intermediate wall. Preferably the multiwall sheet has a flexural rigidity of greater than or equal to 10 N/mm.
摘要:
A structural panel includes a shell having spaced first and second exterior panels and frame members adjacent edges of the panels, and at least one polymeric sheet disposed between the exterior panels and bonded to an adjacent exterior panel. The polymeric sheet is made of a thermoplastic material and has a plurality of openings through its thickness spaced apart by flat wall portions of the polymeric sheet. Stiffeners are disposed between the polymeric sheets and are secured by polymeric end caps. The end caps are made of a thermoplastic material and have a plurality of openings through their thickness for receiving the stiffeners. A foam insulation material fills substantially all the space between the polymeric sheets, stiffeners, and frame members in the shell interior. At least one blast- or ballistic- resistant core layer may be disposed adjacent the at least one polymeric sheet.

摘要:
The present invention provides ultrathin polycarbonate panels for use in security isolation cells to provide a transparent and secure barrier between a prisoner and a guard, where the barrier passes flammability test ASTM E-84 Class A. The panel comprises at least one polycarbonate sheet having a thickness between 0.25 mm and 1 mm. Panels may optionally include a metal support and a frame, and the frame may overbite (edge bite) a portion of the polycarbonate panel, and all points of the polycarbonate panel may be located within four frame widths of the frame.
摘要:
A method of forming an internally-arranged laser-beam weld from within a composite structure. The method includes arranging a welding apparatus within an internal passage of the composite structure, and emitting a laser beam from the welding apparatus to form the internally-arranged laser-beam weld between layers of the composite structure.
