Description

GLAZING OR PANEL AND ITS CONNECTION TO THE FRAMEWORK

Equipped glass, stave or panel and its connection to the framework. Application field

This invention is referred to an equipped glass and to the elements aiming at guaranteeing its connection to the framework. State of the art

In the field of the metal fittings, but not only in this field, it is often possible to fix glasses, staves or panels in various material to a framework. This can be made by aluminium sections or by wood millwork fixed to the building to ensure the stability of the whole structure. The glass (single or double glazing) staves or panels is fixed to a frame in aluminium or wood that winds up its perimeter by the sides. The frame is then blocked on the internal structural components. On the contrary, a more recent technology, particularly used for continuous fagades, considers fixing glasses staves or panels to a frame, generally in aluminium, also put along their perimeter but that faces the loose side and does not surrounds its edge. The glasses, staves and panels thus formed are aesthetically more appreciable in that the aluminium parts making them cannot be seen from outside of the building. On the other side this industrialized technique has some important disadvantages. First of all the seal of the structural fixing of the glasses, staves or panels to the aluminium frame by means of silicone has to be tested in an adequate laboratory, entitled to issue a certification of compliance with the security legislation in force. This causes the need for a series of production steps separated in space and time even to an important extent. First of all the constructional window and door frame fitter produces the frames. These are sent to the glazier who fixes glasses, staves or panels to the frames. Some samples of these external equipped elements are then transported up to one of the above-mentioned laboratories that sees to the carrying out of the envisaged tests. Ttie latter require a long time, therefore the whole production chain is slowed down if not blocked at all up to the issuing of the certification. Lastly the equipped glasses, staves or panels are transported to the construction site and mounted on the facade. As can be easily imagined the transportation costs and the employment of manpower for the several handlings are high.

Summary of the invention

The aim of this invention is that of creating equipped glasses, staves or panels that can be quickly fixed to the framework of a metal fitting, a covering, a facade or any other structure where it is necessary to have a safe fixing of the component parts.

Another aim of the present invention is that of creating external elements without the defects we mentioned before. These and other aims are reached by the equipped glass, stave or panel in the object, according to the enclosed claims.

The equipped glass, stave or panel is fixed - by means of a silicone layer - to a frame made of pieces of section bar in plastic material or aluminium. This frame is directly fixed to the framework or to a part of the structure that can be linked to a framework by means of extensions that are present both on the frame itself and to the framework or on the part of the structure that can be linked to a framework.

One of the extensions of the section bar fixed to equipped glass, stave or panel is supported by an inclined plane of the framework or of the part of the structure that can be connected to a framework.

Detailed description of some preferred examples of execution In details, the equipped glass in object envisages fixing to one double-glazing 1 or to one single glass 2 of a frame made by pieces of a section bar 3 in plastic material or aluminium. The fixing of the double-glazing 1 or of the single glass 2 to the frame takes place by means of a silicone layer 4 in correspondence to an area put along the edge of the single glass 2 or of one of the two glasses of the double-glazing 1 in such a position that the afore-mentioned frame is then interposed between the double-glazing 1 or the single glass 2 and the framework. This operation is carried out directly by the glazier who fixed the pieces of section 3 to the double-glazing 1 or to the single glass 2 by means of a structural silicone layer 4. Therefore the glazier himself sends some samples of the so-formed equipped glass to an entitled laboratory, thus avoiding the costs of transport of the material from the constructional fitter to the glazier himself. Obtaining a certification only for some equipped glasses of a certain dimension enables the fitter to obtain from the glazier the number of equipped glasses needed very fast, in that the guarantee of maximum tightness of the contact materials (double-glazing 1 or single glass 2, silicone layer 4 and section 3) has already been issued before, for those dimensions, by the above-mentioned relevant laboratory. Transportation costs are therefore avoided and waiting for the certifications needed is nearly null. The section 3 constituting the aforementioned frame is preferably standard, so as to be able to be directly hooked to a framework or to a portion of structure that can be linked to a framework with a hooking system as standard, so that the connection between the two parts can be adapted to many situations. What makes the rest of the framework or the part of the structure that can be connected to a framework can on the contrary be as different as may be, without limits that decrease the importance of the invention. In order to obtain the coupling extensions of the section 3 --aiming at connecting with the complementary extensions of the framework or with a part of a structure that can be connected to a framework - are exploited. In detail, section 3 is approximately U shaped, with the U formed by three branches 3.1 , 3.2, 3.3 orthogonal one to the other. Branch 3.1 shows a plane basis facing one of the two glasses of the double-glazing 1 or the single glass 2 and this shape favours its coupling to the silicone layer 4 interposed between this plane basis and the glass. A branch 3.4, facing the opposing branch 3.3 is the loose end of the branch 3.1. It is put approximately at an 90° angle with the branch 3.1 and its function is that of blocking the sliding of silicone during the assembling of the equipped glass.

A second branch 3.5 of the branch 3.1 is facing the opposite branch 3.3 too. The branch 3.2 is level or bent. The branch 3.3 has two first important extensions in branches 3.6, 3.7 facing the framework. Each branch 3.6, 3.7, combining with branch 3.3, delimits a longitudinally developed guide 3.8, 3.9. A protrusion 3.10 is interposed between branches 3.6 and 3.7. Two further branches 3.11 , 3.12 of the branch 3.3 face the corresponding branch 3.4, 3.5 of the branch 3.1. The three branches 3.1 , 3.2, 3.3 delimitate a longitudinal internal guide 3.13, further circumscribed by the opposing branches 3.5, 3.12.

In a first form of execution of the section 3 the branch 3.2 is equipped, on the two ends, with two branches 3.14, 3.15 facing the external edges of the casement that delimitate a guide 3.16 while in a second form of execution it does not have the afore-mentioned branches 3.14, 3.15 and the two branches 3.1 1 , 3.12 delimit a further guide 3.17. In the examples shown in the attached drawings, the most external part of a structure that can be connected to a framework consists of a section 5 in aluminium. In figures 1 to 8, in particular, a section 5 aimed at building the casement of a cell per continuous facade is illustrated, while in the following figures various kinds of sections 5 that form the casement of a fitting are shown. The section 5 is equipped with extensions along the side facing the equipped glass consisting of two branches 5.1 , 5.2. Each branch 5.1 , 5.2 delimits a longitudinally developed guide 5.3, 5.4. Between the two branches 5.1 , 5.2 an inclined plane 5.5 is created. At the time of connecting the equipped glass to the framework the branch 3.6 of the section 3 of the equipped glass is fitted into the guide 5.3 delimited by the branch 5.1 , and the branch 3.7 in the guide 5.4. The branch 5.1 of the section 5 is fitted in the guide 3.8 delimited by the branch 3.6 and the branch 5.2 in the guide 3.9 delimited by the branch 3.7. The protrusion 3.10 of the section 3 rests on the inclined plane 5.5 of the aluminium section 5. This particular conformation of the parts brings the sections 3, 5 in contrast and keeps them firmly coupled. Thus, various advantages are reached: the approach of the two sections 3, 5 is favoured, even in the presence of a certain tolerance in the working of the sections 3, 5; furthermore, the sliding between the same sections 3, 5 is possible when the materials they are made of expand differently. In order to obtain the perfect orthogonality of pieces of the section 3 of the equipped glass, common squares 6 are used, by introducing them in the afore mentioned guide 3.13 delimited by the two branches 3.5, 3.12 or in the guide 3.17 delimited by the two branches 3.11 , 3.12. The same procedure is used for the section 5 of the part of the structure that can be connected to a framework, it also uses the squares 7. In the guide 3.16 of the section 3, external to the equipped glass, an element 8 of support of the glass can be hosted. This would be indispensable in the lower part of the equipped glass to avoid excessive expansions of the silicone layer 4 caused by the weight of the equipped glass itself. Accessory extensions of the aluminium section 5, in combination with those of section 3 of the equipped glass can form guides in which gaskets 9 of contrast between aluminium and glass are fitted. The extensions of the section 3 of the equipped glass, alone or in combination with those of the section 5 of the portion of the structure that can be connected to a framework can enable the joint of further sections 10. One of these, shown in figures 7 and 8, has the task of blocking a panel 11 and to fit the basis of a contention gasket 12 of the silicone layer 4. The section 10 is lodged, in the present example, in the opposing branches 3.4, 3.11 of the section 3 by means of two branches having a cog at the end. It goes without saying that the part that is not commented here of the portion of the structure that can be connected to a framework or of the framework can have any alternative form. What is decisive is only the fact that the part of the structure that can be connected to a framework or the framework itself is equipped, along the facade facing the section 3 of the equipped glass, with extensions able to lodge in complementary extensions of the section 3 itself.
