Abstract

The invention relates to fixed glazing for a building, comprising at least one glass pane, for example triple glazing. According to the invention, the glass pane is directly inserted in the adjacent building structure without interposing a frame that consists of a rigid material, and/or it is inserted in the laterally adjacent insulation of the building structure.

Description

 fixed glazing

The invention is directed to a fixed glazing for a building, with a glass pane, eg. 3-fold glazing.

Glass panes are usually taken in a frame - for example made of plastic, wood or metal - and used together with that in the relevant building construction, anchored, sealed and finally plastered. This procedure is not only very time-consuming; In addition, the frame can be a kind of thermal bridge compared to a high-quality glazing.

From the described disadvantages of the prior art, the invention initiates the problem of developing a generic fixed glazing such that thermal bridges are avoided as much as possible and / or installation with the least possible effort to accomplish. The solution to this problem is achieved by the fact that the glass pane is used directly in the subsequent Bau-Kostruktion, without an intervening inserted frame made of a rigid material, and / or it is inserted into the laterally subsequent isolation of the construction construction. By avoiding a frame, the risk of forming a thermal bridge is reduced. A further reduction is possible in that the glass plate directly adjoins the lateral insulation, so it is not shifted away from this in the shell. The latter is made possible in particular by the fact that a stable insulation is used in any case in the vicinity of the relevant fixed glazing, in particular extruded polystyrene (XPS, often used as so-called. Perimeterdämmung). This insulation is firmly anchored to the shell, for example

CONFIR ATIOW COPY by gluing. Preferably, a groove is incorporated into this viable insulation along the visible inner edge, the depth of which corresponds approximately to the thickness of the relevant glass pane. After the glass sheet is inserted into this groove, it is fixed therein, for example, by pouring the remaining gap by means of a liquid, hardening plastic, z. As a casting resin, or a hardening, mineral substance such. B. water glass.

By the glass sheet is inserted into an all-round groove of the subsequent construction, in particular thermal insulation, it can at least partially supportive includes and guided wreden.

The glass sheet should consist of two or preferably three layers, of which the outermost one is slightly smaller than the other (n), so that the inner layer (s) extends into a groove in the adjoining construction, in particular thermal insulation (FIG. On the other hand, the outermost layer can slide on the inner edge of the grooved part.

The invention recommends that the glass pane is glued at its edge with a completely running band. On the one hand, this is a protection for the particularly endangered edge area of a pane, from which cracks very often emanate; On the other hand, the surrounding structure can optimally connect to a strip with a comparatively rough surface finish, so that the formation of cracks along the joint between the glass pane and the construction is reduced. The invention can be further developed such that the glass pane is sealed or fixed to the surrounding structure, for example by a cured synthetic resin, in particular cast resin, or by a hardening, mineral substance, in particular water glass. As a result, the formation of leaks and thus the ingress of water od. Like. Counteracted. Finally, it is the teaching of the invention that a flexible sheet material, for example of ethylene-propylene-diene rubber (EPDM), preferably drawn on the outside over the glass sheet and is glued thereto. In particular in the roof area, a flexible foil roofing material, for example ethylene-propylene-diene rubber (EPDM), can be pulled over the edge of the glass pane and bonded thereto.

Further features, details, advantages and effects on the basis of the invention will become apparent from the following description of some preferred embodiments of the invention and from the drawing. Hereby shows:

1 shows a section across a fixed glazing according to the invention, which od in particular also for vertical glazing on walls. Like. Is suitable; and Fig. 2 shows a section across a fixed glazing according to the invention, which od especially for horizontal glazing on roofs. Like. Is suitable.

In both figures, a glass pane 1; 1 'with three layers 2; 2 'used. Of these, two layers 2 are the same size; the third, outermost is slightly smaller, so that there is an all-round groove 3; 3 'results, about one third of the depth of the entire glass pane 1. The glass sheet 1; V may be pasted at its edge with a band running around, which the glass sheet 1; 1 'protects itself during installation and also one for connection to a surrounding building structure 4; 4 'brings optimal surface texture. In the installed variant 1 according to FIG. 1, such a glass pane 1 is used in a blunt manner in a corresponding recess, in particular in the area of thermal insulation 5, for example of XPS boards. In between a film 6 can be used, for example. An EPDM film, z. B. with a tab which engages in the groove of the glass sheet in the region of the outermost layer. This EPDM film 6 may be glued to the glass sheet 1. This mounting method is particularly suitable for vertical glazing in walls, because the glass pane 1 is then seated with its lower edge on the soffit of the relevant wall or insulation recess and thereby the weight of the glass sheet 1 is completely absorbed.

2, in the insulation 5 ', which preferably consists of XPS or a comparably stable material, an edge 7 running along the recess 7 is incorporated, which approximately corresponds to the thickness of the glass pane 1'. equivalent. Therein, the glass sheet 1 'is used.

Preferably, this is a roof glazing, so that the glass pane V along its edge from the flat bottom 9 of the groove 8 under handles and thereby the weight of the glass pane V is collected.

Preferably, a film 10 forming the actual roof membrane, for example of EPDM, is first folded or bent into the groove 8, so that it lies in the region of the groove 8 between the glass pane 1 'and the thermal insulation 5' and there for a first seal provides.

A possibly remaining gap between the circumference of the glass pane 1 'and the groove 8 in the reveal of the recess 7 in the region of the thermal insulation 5' can be poured, for example with liquid plastic or with another, preferably suitable for exterior sealing or grouting material 11th Preference is given to a elastic material which is capable, for example, thermally induced

Relative expansions between glass pane V and reveal or heat insulation 5 'compensate. Finally, an EPDM film 6 'or the like can be spread over the edge of the glass pane 1, in particular in such a way that it dips into the groove 3' of the glass pane V next to its outermost layer 2 '. Thus, an optimal seal can be achieved, in particular when the EPDM film 6 'is fixed by means of adhesive along the edge of the glass pane 1'.
