Method for the assembly of curtain walls and wall element, in particular for carrying out the
Procedure

The invention relates to a method for assembling a
a curtain wall consisting of posts and bars
Building and a wall element in particular for carrying out the method.

In principle, two different methods for creating a passage from curtain walls are known. at
In one type of construction, the entire curtain wall consists of individual wall elements that have the height of one or more storeys. These wall elements
are self-supporting and are, for example, attached to the ceilings of the building. The assembly of this
Wall elements on the building are made with the help of a
Winch or a crane that pulls up the wall elements on the outside of the building. This work is

time-consuming and both the wall elements to be installed and the wall elements already installed can damaged during assembly. The pulling up of the wall elements can therefore only be carried out very slowly and because of the relatively large areas

the elements are exposed to wind forces. Furthermore, this type of construction requires more effort Joint seal that is easy to produce at the construction site is necessary. Because of this, there are also TO get wider post views, for example one Minimum width of 100 to 120 mm, which is often undesirable for aesthetic reasons.

An advantage of the construction with wall elements is that a not insignificant part of the Work can be carried out at home in the workshop including the installation of parapet elements and glasses.

Another possibility of creating a facade is that the ■ glazing and the facade panels load-bearing posts and transoms are delivered individually to the construction site and only there on the outside of the building themselves can be put together to form a facade framework, the infilling of the framework with parapet elements and glass takes place from the outside and again then strips and sealing profiles must then be attached, usually with the help of a scaffolding or a gondola, which is arranged on the outside of the building so that it can be moved in all directions is. Under the same conditions, the aluminum weight is the one created in this way from mullions and transoms Façade higher than that of a similar façade created using element construction.

An advantage of the latter type of assembly using · mullions and transoms is that overall the working hours, and especially those in the workshop, are shorter than with element construction. Farther the latter assembly method gives the possibility of narrower rung views.

The invention is based on the object of creating a method with which the curtain wall of a building can be created in the shortest possible time and with the risk of damage to the curtain wall or its Elements and a risk to the assembly personnel is almost excluded, i.e. the advantages of both construction methods to unite as far as possible while largely avoiding the alternating given above Disadvantage.

This object is achieved according to the invention characterized in that a number of posts and bars are pre-assembled on an auxiliary frame to form a wall element be that the wall element is transported on the subframe to its hanging location that the wall element on the hang-in location is attached to the building in such a way that the cohesion of the posts and transoms is guaranteed and that the frame is removed from the wall element and transported away from the wall element.

In the method according to the invention, the advantages a post / transom construction combined with the advantages of an element construction. The mullions and transoms can in their respective length

measurements are already being delivered while still on Shell is being worked. The time-consuming and not harmless installation on the outside of the building is no longer necessary. because the posts and transoms are pre-assembled on the subframe, which on the one hand happens faster and on the other hand can be done on a safe work surface.

So that this preassembled unit of the wall element is not during the transport to its hanging location may fall apart, preferably only the Post releasably connected to the subframe. For this purpose, differently designed locking mechanisms can be used on the subframe Smitt el be provided, with the help of which the posts can be screwed or clamped.

While with the pure post and transom construction only the skeleton of post and transom on the outside of the building is pulled up and then the glazing and facade panels are attached, The glazing and the facade panels or the like can preferably also be attached to the subframe be pre-assembled.

to reduce the assembly time and the dangers to keep low those from the long transport routes of pre-assembled curtain elements from the ground to their The final destination will be the curtain wall items such as posts, transoms, glazing and panels stored on certain floors of the building, on which the pre-assembly on the subframe he follows.

This pre-assembly can preferably take place on a mounting frame, of which in the embodiment of Invention, the pre-assembled wall elements up to their attachment point in the area of the outside of the building

It can be provided that the wall element with the subframe is attached to the hoist for transport. The posts and bars are not very stressed during transport, so that their attachment to the subframe can be made relatively simple. A lifting eye can be provided on the subframe, with which the wall element is attached to the hoist outside the building.

Each of the with the inventive method at the Wall elements to be attached to the outside of the building can consist of at least two posts, depending on the size of the glazing and panel surfaces also made of, for example, five posts and of at least two, preferably three, connecting the posts to one another Bars exist. The middle post can be a closed profile and the outer edge post can be an open one Have a profile.

The connection of the bolt to the post can be done by attaching it to the post provided. These cones can be used both on the. Posts screwed on or be welded, they can also be integrally formed on the post. About the linear expansion To take into account the bars, the bars preferably have a length that is slightly shorter is than the clear distance between the posts.

To connect two edge posts with an open profile to form a post with a closed profile to be able to, the edge posts can be designed with a tongue or groove, which each interlock.

Furthermore, it can be provided that the edge posts have legs whose position is offset so that they sit on top of each other without play after joining. The connection of the open profiles of the edge posts can be done using screw bolts. To accommodate sealing strips or spacer strips can the posts can be provided with, for example, dovetail-shaped grooves, in those with dovetail-shaped grooves Sealing strips or spacer strips provided with springs can be inserted. These sealing strips and spacer strips are used to plant the glazing to be attached between the posts and transoms, respectively the facade panels, which can be made of sandwich construction, for example. The panels can consist of a glass pane and a metal wall, between which an insulating material is provided is. It is also possible to have the panels on both sides with a metal plate, for example made of aluminum or stainless steel.

For easy fastening of the facade panels or the glazing, the posts can have corner recesses on the outside have, to which the glazing and the panels can be attached. The glazing and the panels can be clamped to the post via yoke-like strips. To protect the Screw connection and the sealing strips against rain and other weather influences can be attached to the yoke-like Terminal strips cover strips can be provided so that they can be clamped.

The posts of the individual wall elements can be connected to one another via adapters or they are aligned with one another without direct connecting means. g _m, the length dimension of the post to take into account an appropriate distance is maintained between the posts, so that a horizontal expansion joint excluded
