DE3421901A1 - CURTAIN FACADE FOR BUILDING - Google Patents

Description

description

The invention relates to a curtain wall for buildings, which has parapet and window elements, which on Floor ceilings of the building are attached or attachable.

Such curtain walls are known in many types and forms. In the facade area of the building the (front edges of the) storey ceilings are regularly made of vertical profiles made of steel (or from Aluminum) connected to each other. The parapet elements and window elements are - one above the other - on these profiles attached. Since the profiles bridge the (vertical) distance between adjacent floor slabs, they are able to transfer the forces caused by wind pressure to the floor slabs.

The division of the functions of a curtain wall on a vertical, static requirements sufficient Support frame on the one hand and on parapet and window elements to fill in the facade openings on the other represents a not inconsiderable cost factor, makes fire protection more difficult and naturally limited the architectural design options.

The invention is therefore based on the object of specifying a curtain wall construction and arrangement.

which works without vertical supports.

This object is achieved according to the invention in that the parapet elements are self-supporting, each covering the front side of a floor slab and on this Fixed or attachable cassettes which hold the window elements between them. In this way, the static link that has been used up to now is established the floor slabs one below the other (by a bevy of vertical beams). This is going through allows the aforementioned arrangement and type of attachment of the parapet cassettes. These take over (additionally) the static function of the wind load transfer and at the same time offer the necessary fire protection against the danger of a projectile in the overlying flames.

The assembly of the cassettes is resistant to bending moments regularly from several - generally two - one above the other arranged fastenings on the storey ceiling and / or a joist (lintel) or the like integrally connected to this. It has been shown that between such trained, arranged and fixed parapet cassettes easily - i.e. without additional static Measures - the window elements can be attached. In this way, curtain walls can be used horizontally create continuous ribbon windows without interruption by vertical supports (apart from, of course of the vertical frame members of the blind and window frames, which are required in any case).

The cassettes preferably consist of sheet steel trays, the floor of which is attached to the building. These can be with

provided additional vertical stiffeners and also filled with thermal insulation material.

For essentially aesthetic reasons, provision can also be made for a viewing panel to go with the parapet cassette belongs, which covers the tub and can optionally be mounted separately from this.

The drawing illustrates the invention using exemplary embodiments, namely shows:

Fig. 1 in vertical section a detail from a curtain wall according to the invention after they have been attached to a building;

FIG. 2 shows a representation corresponding to FIG. 1 of a modified embodiment; FIG.

Fig. 3 is a composite of two parts) Parapet cassette in front view;

FIG. 5 shows a vertical section along the line V-V in FIG. 3.

Figure 1 shows a schematic representation of a building the floor slabs 1, which in the area of the whole with 2 designated facade to a lintel-like girder 3 are thickened. On each floor 1 with the Beam 3 are parapet elements attached in the form of cassettes, in such a way that they the end face 5 of the Cover floor slab 1 (with the girder 3) as well as upwards into the area of the one above Floor and protrude down into the area of the floor below.

The cassettes 4 are fastened at a vertical distance by means of angle irons 6, 7 both on the top of the Floor ceiling 1 as well as on the underside of your girder 3. The direct attachment of the parapet cassettes 4 on the ceilings 1 allows these as fire protection elements against flashover of to insert one floor into the one above; it regularly does not cause any difficulties for this The required minimum height of the cassettes of 90 cm must be provided.

The cassettes 4 are filled with thermal insulation material 8 and, for example, on the outside of the building colored glass existing plate 9 covered. Figures 3-5 show that the tub 10 is made of sheet steel, which essentially forms the cassette 4, is stiffened by supports 11, which in the example consist of rectangular tubes. In the area of these stiffeners 11, the cassettes 4 are on the floor slab 1 (or the girder 3) anchored.

The in this way rigidly attached to the respective floor slab 1 (but also only to this) cassettes serve in turn to fasten the window elements in such a way that each of the two adjacent storey ceilings 1 belonging parapet cassettes 4 hold the intermediate window elements 12.

The interior parapets indicated in the drawing 13-have no connection to curtain wall 2 and none either static function.

In the embodiment of Figure 2, there is a difference only insofar as the girder 3 of the storey ceiling is relocated a little further into the interior of the building. Therefore, the cassettes 4 with the help of the angle irons 6, 7 only fastened against the end face 5a of the floor slab 1, but anchor supports 14 are also provided, which the cassettes 4 additionally at a distance from the respective girder 3 on this - and thus opposite the Storey ceiling 1 additionally rigid - keep it.

Figures 3-5 show an 'empty' cassette 4 in frontal view and in sections. In this case - because of its great width - it is composed of two parts, which are connected to one another along a joint 15. These representations can be clearly seen the cassette structure from each of a tub 10 and vertical stiffeners 11, which in the present case consist of rectangular tubes. You are welded to the tub 10, and indeed - as before all Fig. 5 shows - with the forward (outward) cranked upper edge of the tub 10. On the opposite - Lower - the stiffeners 11 are cut at an angle and left open so that they can with the The corresponding lower edge of the trough 10 forms an acute-angled slot 16. Even after filling the tub 10 With thermal insulation material 8, condensation water can escape in this way, which occurs when there are temperature differences possibly reflected in the stiffeners 11.

The fastening of the cassettes 4 takes place through the reinforcements 11 on the respective floor slab 1 or a girder 3 or the like, so that the transmission of bending moments is guaranteed without buckling.
