Curtain wall for buildings

State of the art

The invention is based on a curtain wall for buildings according to the type of the main claim. Such curtain walls are known in many ways. In these known curtain facades, the rails are used for guidance of special vehicles that have a work cage in order to move the windows and possibly other facade parts out of this work cage to be able to clean. Repairs with such a vehicle are also possible to a small extent. The rails are retrofitted after the facade elements were installed, fastened, for which either fastening devices are provided on the facade elements or by using the facade elements protrude from the building. The brackets of such rails then also serve in part as brackets for stationary fire escapes or scaffolding. In any case have this type of rails have the disadvantage that they require additional assembly costs require expanding the building outwards and, last but not least, looking unsightly. In addition, these can be placed in front of the actual facade Structures are used by burglars as a means of climbing.

Another disadvantage of this known curtain wall is that too their assembly either a scaffold must be built or one of the

building height corresponding crane must be used. In both cases, considerable costs are required, mostly in connection with traffic obstructions. In many cases, however, neither the establishment of a framework ^is still possible a sufficiently high crane built up. In addition, at

the transport from the ground to the point where the facade element is mounted is to be, there is a risk that the prefabricated facade element, if only slightly, is damaged anyway - and if it is only slight scratches are - which then gives rise to complaints and price deductions. Such damage often only occurs when the rails are installed for the Cleaning vehicle. The effort for the assembly of the known curtain wall is not only that it is very expensive, but also time-consuming. This works , not only in high wage costs but also in the loss of profit of the

r homeowner. This well-known cumbersome assembly is also possible with rental

! associated risks, as such facade elements are difficult to grasp

are.

Advantages of the invention

The curtain wall according to the invention with the characteristic features of the The main claim has the advantage that the facade elements with the aid of the transport vehicle safely and quickly and, above all, without damage can be transported to the assembly site. Once assembled through Façade elements consist of rail pilasters, the façade elements can be transported via the vehicle. No scaffolding is required and no crane either, and the assembly routes are also minimized. the In addition to assembly, the curtain wall according to the invention is also cheaper to manufacture than known curtain walls, since those made in workshops Prefabrication can be streamlined. Since the rail pilaster at their The ends are open at the bottom and at the top, depending on the design and arrangement of the track, the roles can also be introduced or executed very easily will.

The same rail pilasters that were used when installing the facade elements Serve guidance of the vehicle, can advantageously later as rail pilasters serve a cleaning vehicle. Because the rail pilaster strips

do not protrude beyond the facade surface, can advantageously on from i>

Structures protruding from the building are dispensed with, on the one hand strong winds can generate unpleasant noises and on the other hand could serve as a means of climbing for a burglar.

According to an advantageous embodiment of the invention, the rail pilaster strip a forwardly open U-shaped cross-section, the track being designed in two parts, namely one part on each of the two free U-legs. As a result, the transport forces can be evenly transferred to both half-pilaster strips through the rollers, with the use of two rail pilasters by the vehicle, these forces are even transmitted to three facade elements, namely one-way to the one between the rail pilasters and then on the elements to the right and left of it.

According to a further embodiment of the invention, each facade element a frame for receiving the configuration corresponding to the purpose, such as insulation, windows and the like, the facade element through this frame is attached to the building and the frame consists of profile rods at least in the vertical end faces. By prefabricating such Facade elements can be installed in such a frame in a rational manner and without assembly or fastening difficulties, what such a curtain facade can accommodate. This includes not only the window frames with window panes but also any blinds and motors for adjusting the blinds and possibly radiators and air guiding elements. In any case, however, insulating material. These refinements corresponding to the purpose can simply be attached to the frame The frame itself consists of profile bars of different cross-section can exist, which can be appropriately designed and connected to one another. It is particularly conceivable that the frame is made in this way are that the facade elements are in particular with their outer surfaces in an overall plane that they can be plugged together on their upper and lower sides are or that they run in the horizontal direction from the outside behind the rail pilaster.

According to a further embodiment of the invention, the transport vehicle a guide carriage guided by rollers in the rail pilasters, which has at least two running in a rail pilaster and each on a carriage

l ··

side part has arranged rollers, the carriage side parts by at least a traverse, which is preferably also used to attack the hoist, are connected to one another.

Such a roller guide of the vehicle can be designed in different ways be. There can be two tracks on the rail pilasters, namely one after inside and one acting outside may be provided, and of course there can be rollers mounted further inside or further outside on the slide side parts be present, which give the slide a clear guide in every lall. During assembly, when the guide carriage comes out of the rail pilaster strips emerges and the roles can no longer transmit force, the facade elements, which are no longer guided with the interposition of the now freely hanging vehicle, very easily moved by hand into the end position will. In any case, the facade element is moved at a distance from the elements that have already been installed on the possibly long transport route.

Depending on the distance between the individual rail pilaster strips or the width of the facade elements can be changed according to an embodiment of the invention, the distance between the rail side parts.

The slide side parts each have a supporting plate and bearing the roller bearings a cantilever arm which is arranged on this support plate and points away from the building, the cantilever arms being connected by the crossbeam and to the free ones Ends of the cantilever arms the facade element is suspended. Once the roles emerge from the guide rails during assembly, the slide side parts are positioned due to the offset points of application of the tensile forces, namely on the one hand the hoist on the traverse and on the other hand the facade elements at the ends of the cantilever arm, at an angle, with the lower end of the 4-way carriage side parts being swiveled towards the building. This achieves that These parts can possibly be supported on the building in order to prevent the facade element that has just been transported from bumping into the already assembled one to avoid, or to give the moiteur the opportunity without bending over to guide the now free element by hand.

Further advantages and advantageous embodiments of the invention are The following description, the drawing and the claims can be found.

Description of the embodiment

In. 1 shows a detail of a front view of a building 10 which IeJlWe ⁵ Se ₁ is clad by facade elements 11. These facade elements 11 all have the same length and width, namely the length at floor level and the width according to a divider, as is determined, for example, by the spacing of the building pillars 12. The fiber thread elements 11 are prefabricated and, in this exemplary embodiment, are arranged in such a way that the window part 13 is arranged behind the wall cladding part 14. There are mainly practical reasons for this. In the section 14 of the facade element located above the window 13, drive parts of a window blind or other elements can be arranged. In addition, the window section 13 is usually heavier than the wall cladding section 14, so that when the facade element is transported upwards, the heavier part hangs down and thus has a stabilizing effect during transport. In addition, the fastening devices provided at the upper and lower end of each passage element for assembly are just at the height of the building parapets 16, so that the fitter 17 can very easily attach the facade element 11 to the structure 10 and the anchors preassembled there. Of course, instead of the combination of window section 13 and wall cladding section 14 of a facade element 11, two wall cladding sections 14 can be combined to form one facade element 11, for example if only one wall section is to be clad.

cut 14 one of the Schisnenüsenen IS is provided. The facade element 11 each have a frame 28 made of profile material, which is inherently stable and carries insulating material 29 or glass window frames 31. This frame 28 can, depending on the intended use, for example as a wall cladding element or window element, sometimes also as a passage element a bridge or a balcony can be designed differently. What they have in common, however, is that it is prefabricated in a workshop and the entire facade element is mounted on its own before it is then mounted on the building 10. For this Mounting brackets 32 are arranged on the supports 12 of the building 10 which the frames 28 are suspended via brackets 33 and secured by screws 34. The frames 28 also carry windows 35. Also on the vertical ones Sections of this frame 28 are attached profile rods 36 which are angled at their outer free end at 37 and one in each pair Form rail pilaster strips 18.

Of course, the facade elements 11 can also be attached to the building 10 done in a different way. The type of installation shown is particularly simple and advantageous. So, of course, the window 35 after assembly of the Façade elements are used and, for example, the wall cladding section 14 of a façade element can also be used instead of the building pillar 12 can be attached to the building parapet 16. Between the layer of insulating material 29 and the outer, mostly anodized screen 38 is a cavity 39, which is open at the bottom and in which light shutters 41, such as, for example, blinds, can be retracted, which downwards if necessary can be lowered in front of the glass pane 35, with them in guide rails 42 slide, which are attached to the profile rods 36. Of course is here too Another construction is conceivable, for example that the blinds are provided on the inside of the glass panes 35, thereby making them less sensitive to wind to be. Instead of sun protection elements, of course, grain Combined sun protection solar collector elements are used when the sun is shining are extended and with the help of which heat is collected and transported in a known manner to a heat accumulator.

The transport vehicle 19 shown in plan view in FIG. 2 is a guide carriage formed, which has two slide side parts 43 which are connected to one another by a cross member 44 and support straps 45. At the tram

verse 44 attacks the transport rope 2i at 46. On the side panels 43 are provided on the right and left guide rollers, of which the front guide rollers 47 are located on a front track 48 of the angled profile rods 36, 37 are supported, while rear guide rollers 49 are supported on a rear track 51 formed by the angled portion 37. Of the Once inserted into the rails, the slide side part 43 is thus largely positively guided by the pairs of rollers 47 and 49.

In Figures 3 and 4 is for the transport of the grip elements 11 and a basket for passenger transport serving guide carriage 19 in the side = view with facade element 11 (Fig. 3) and shown in the rear view with basket (Fig. 4) in relation to Fig. 2 enlarged scale.

The slide side parts 43 consist of a support plate 52 and an approximately welded cantilever arm 53 protruding forward in the middle of the support plate 52. The support straps 45 are attached to the support plates as well two pairs of front guide rollers 47 and smaller rear guide rollers 49. The angled part 37 of the profile rods 36 is shown in phantom in FIGS. 3 and 4, the front, larger guide rollers roll on the track 48 and the smaller, rear guide rollers 49 on the rear track 51. In addition to these, the support plates 52 in the facade level leading guide rollers 47 and 49, two further support rollers 54 are attached to the upper and lower ends of the support plate, which, as shown in FIG. 4 can be seen, on the right and left of the rail strip 18, specifically on the facing end edges 55 of the angled sections 37 of the Support profile rods 36. This also creates a vertical guide within the facade level achieved. These support rollers 54 are arranged on the support plate 52 via bearing straps 56.

The cross member 44, which has an eyelet 57, is fastened between the cantilever arms 53 for the engagement of a crane hook 58 which is provided at the end of the transport rope 21. On each of the cantilever arms 53 there is also a use 59 provided as an additional option for intervention. Arr. free end of the cantilever arms 53 are each pivotable via a screw connection 61 in FIG. 3 for the transport of elements and rigid in FIG. 4 for the transport of people Lugs 62 are arranged, on which the facade element 11 or a transport basket 65 carrying a person 64, likewise via a screw connection 63 is hung.

In Fig. 3 this guide carriage 19 is shown in the normal working position. However, as soon as this working carriage emerges from the rail pilaster, it pivots around the eyelet 57 with its due to the center of gravity situation lower file to the rear, so that the facade element 11 to him about the position shown in phantom.

Of course, the t-guide slide can also be designed differently. Authoritative for the invention is that the guide carriage is used during the construction of the curtain facade by already assembled facade elements
