Description

1 Curtain wall and set and construction method for such a curtain wall. Field of the invention The present invention relates to a curtain wall and a set and construction method for such a curtain wall. 5 Background art to which the invention relates A curtain wall is a structure of mullion profiles and transom profiles in which panels, usually glass panels, but possibly also closed panels, can be placed to form a nonload- bearing outer wall. A disadvantage of the known curtain walls is that the mullion profiles and transom 10 profiles are designed to be built from the outside to form a structure of profiles. Also, the panels must then be installed from the outside. This is complex, especially when construction must be done at certain heights and requires scaffolding or suspended working platforms and it is dangerous for the persons who perform this work and for those who might pass under it. 15 An installation of the panels from the inside would be much easier and safer because there are floors at regular intervals. Also, the known systems of mullion profiles and transom profiles require a large number of components and a large number of actions to assemble them. From US 3.266.210 a curtain wall structure is already known with transom profiles 20 mounted between the mullion profiles and whose assembly of the mullion profiles and the transom profiles can be performed from within. With this known structure, the transoms are snapped into place in the mullions, which, as a disadvantage, can cause the transoms to come back loose, with all the disastrous consequences thereof. 25 Another important disadvantage of this known structure is that it does not solve the problem of tolerances. Date Re1rue/Date Received 2023-10-12 2 In the case of a curtain wall, two types of tolerances can be distinguished, on the one hand, the manufacturing tolerances due to the limitations associated with accuracy in production, and, on the other hand, the construction tolerances due to the installation in situ. 5 In addition, the transom profiles must be mounted at their ends between the mullion profiles in order to allow for the thermal dilatations of the transom profiles on the one hand, and the differential settlements of a building, which are inevitable and inherent to a concrete or steel structure, on the other hand. However, this engenders to the connection between the mullions and the transoms not 10 being watertight, which can result in leaks, which is obviously inadmissible for a facade. The curtain wall structure does not provide a seal between the mullions and the transoms, because of the specific assembly method by rotating the transoms, this method does not provide enough space for a seal to be applied at that place. Moreover, a seal using an elastic kit would not offer a durable solution at that place, 15 given the metal to metal connection and the inevitable thermal expansion and shrinkage of the metal transoms. Additionally, this structure does not allow for tolerances, such as are inevitable in the production and assembly. Summary of the invention 20 The object of the invention is to provide a solution to the aforementioned and other disadvantages and relates thus to a curtain wall comprising mullion profiles, transom profiles and one or more panels, wherein the mullion profiles extend vertically, wherein the transom profiles are each attached to two mullion profiles and extend horizontally, wherein the mullion profiles are provided on each side with a groove to receive the side 25 edge of a panel, wherein the grooves have an access opening, wherein the access opening has a first fixed dimension or width in the horizontal direction, wherein the transom profiles in the horizontal direction and at right angles to the profile direction of the transom profiles, have a second dimension, wherein the second dimension is larger than the first dimension, wherein the transom profiles in a non-horizontal direction at Date Re1rue/Date Received 2023-10-12 3 right angles to the profile direction have a third dimension, wherein the third dimension is smaller than the first dimension, so that the ends of the transom profiles, in a rotated state of the transom profiles in Date Re1rue/Date Received 2023-10-12 4 the profile di.rection and with a :r:od i.n.serted in the p.:rojecti.:ng out :from the undercut groove, thereby blocking a .ri:>tational movement of the transom profiles.
