A system for assembly between a connecting element and at least one cavity positioned on a surface portion situated on an edge face of a substrate, particularly made of a fragile material of glass type. The connecting element is configured to be accommodated in the cavity that has curved and retaining walls, the cavity being made at the edge face of the substrate.

Linking elements designed to equip panels, in particular glass panels, for fixing and panels equipped with same

According to this process for manufacturing a laminated glazing unit so that it withstands predetermined stresses, a reference laminated glazing unit is identified that withstands the predetermined stresses and that comprises at least one substrate and one interlayer having the same chemical compositions as those of the laminated glazing unit to be manufactured; the tear strength (J) of the interlayer of the reference laminated glazing unit, and also the interlayer thickness (e) and the substrate thickness (e) of the reference laminated glazing unit are then determined; then, using a graph (C) representative of the minimum interlayer tear strength (J) required so that any laminated glazing unit, comprising at least one substrate and one interlayer having the same chemical compositions as those of the laminated glazing unit to be manufactured, withstands the predetermined stresses, as a function of the interlayer thickness (e) and/or of the substrate thickness (e), a combination of optimum values (e, e) of the interlayer thickness and of the substrate thickness is deduced; the laminated glazing unit is then sized with an interlayer thickness (e) and a substrate thickness (e) that are greater than or equal to the optimum values (e, e).

Process for manufacturing a laminated glazing unit and laminated glazing unit

A process for manufacturing a laminated glazing unit so that it withstands a predetermined load, in which the unit includes at least one substrate having a glass function and at least one layer of polymeric interlayer. The process: obtains viscoelastic behavior of constituent material of the interlayer; calculates maximum value of at least one quantity representative of the loading resistance of the laminated glazing unit subjected to the predetermined load; adjusts dimensions of the unit such that the calculated maximum value of the quantity representative of the loading resistance of the unit is less than or equal to a permissible maximum value; and the or each substrate and the or each layer of interlayer are prepared and assembled to the adjusted dimensions.

Process for manufacturing a laminated glazing unit

A process for manufacturing a laminated glazing, in which a lamination interlayer is interposed between two substrates having a glass function, including: making a measurement of Young's modulus E on a sample of the interlayer, using a viscoanalyzer, by varying temperature and frequency while imposing a constant dynamic displacement; making a numerical treatment of curves obtained, using WLF (Williams-Landel-Ferry) equations, to establish a law E(f) governing behavior of a material constituting the interlayer sample at a given temperature; producing a numerical model based on a finite-element method in bending of a laminated glazing panel, wherein mechanical properties of the sample result from the preceding operations; comparing results of the numerical calculation with those obtained with analytical formulae in which participation of the interlayer in transferring shear in the laminated glazing is represented by a transfer coefficient &#x3c9;; varying the transfer coefficient &#x3c9; in the analytical formulae until results converge; and constructing a transfer function &#x3c9;=f(E) by successive iterations.

Process for manufacturing a laminated glazing

A fastening device for substrates, for example for glass substrates assembled as a multiple glazing unit, including retaining elements placed between at least one of the two substrates facing one another and a supporting structure for transferring loads of the substrates to the supporting structure. The retaining elements include a mechanism to compensate for dimensional variations. The compensation mechanism allows a relative movement between the substrates.

Device for fixing substrates, in particular glass substrates

A connecting system configured to secure at least one cavity including curved and retaining walls and positioned on a surface portion located on an edge of a substrate made of a fragile material of glass type and a support member. The connecting system includes a shoe including at least one appendage projecting from at least one of faces of the shoe, the appendage having a profile that complements the profile made on the surface portion situated on the edge of the substrate.

Connection systems intended for equipping plates, especially glass plates, for the purpose of fastening them, and the plates thus equipped

A luminous structure includes at least one light-emitting diode emitting radiation within the ultraviolet or the visible spectrum, a substantially planar glass element having main faces and an edge around a periphery of the main faces. The glass element includes a hole housing the diode, and a metallic element connected to the diode and coupled with said glass element for removing heat. The metallic element is chosen from an electrical connection element or a holding element for keeping the diode in said hole. The invention also relates to the manufacture of this luminous structure and to its applications.

Luminous structure comprising at least one light-emitting diode, its manufacture and its applications

A fixing system for fixing a panel of fragile material to a bearing structure, including at least one point fastener engaging with at least one first contact region produced in the panel. The point fastener includes a first anchoring part at a first contact region and a second anchoring part at a second contact region situated on the panel. The first and second anchoring parts are connected by at least one adjusting device configured to bring the first and second anchoring parts to bear against the first and second contact regions respectively and are situated in the plane of the panel.

System for fixing a panel made of brittle material

An insert configured to be received or formed in a glass plate to allow, in cooperation with a connecting element, the glass plate to be mounted on a support. The insert is designed to be received in a hole made in one face of the plate, the hole being bounded by a retaining side wall of curved profile directed toward the inside. The insert includes a fastening mechanism complementary to a mechanism carried by the connecting element for connecting the plate to the support.

Insert in the form of a threaded bushing, which is designed to equip and fix plates, for example, glass plates, and plates thus equipped

A method for selecting a polymeric insert to be chosen for its mechanical strength qualities to be incorporated into construction of a laminated glazing. The method evaluates the tear strength of the insert, and evaluates adhesion of the insert to at least one glass substrate.
