Definitions

  • the present invention relates to a curtain wall.
  • curtain walls that primarily consist of glass facade panels that are placed in a construction consisting of vertical elements, called posts, and horizontal elements, called rails.
  • the posts and rails are connected together by cruciform supports that are fastened to a post, and of which two wings are fastened to rails, and if need be rest on a nose of the rails, for example in a supporting structure made of aluminium profiles. It goes without saying that such supports can also be constructed with one wing for use with posts that only have rails on one side.
  • the facade panels for example glass panels that can be relatively heavy, then rest on the supports, which transmit the weight of the facade panels to the posts via the rails.
  • Such supports are known from DE 19854203 , DE29912697 and EP 1460191 for example.
  • the supports together with the rails to which they are connected, can bend under the weight of the supported facade panels. This can lead to a rail touching the underlying facade panel, which can be damaged as a result.
  • a solution for this is to use deeper rails, i.e. rails that extend over a greater horizontal distance, which is aesthetically unattractive and of course is more expensive on account of an increased use of materials.
  • Deeper rails also only have a limited effect on the rigidity of the rail, because while the dimensions of the rails are indeed larger in the horizontal direction, but they are generally hollow profiles such that the rigidity in the vertical direction only increases to a limited extent, while bending takes place in the vertical direction.
  • Wings of the traditional supports cannot be made more rigid by giving them a greater height, because the height is limited by the vertical distance between two facade panels, which must be kept small.
  • the purpose of the present invention is to provide a solution to the aforementioned and other disadvantages, by providing a curtain wall as defined in claim 1.
  • the wings of the supports may possibly bend slightly under the weight of the facade panels, without this bending being passed on to the rails.
  • the wing is essentially T shaped here, viewed in the vertical cross-section, whereby the reinforcing rib is formed by the head of the T.
  • reinforcing rib extends both upwards and downwards.
  • this reinforcing rib after construction of the curtain wall, must be alongside the facade panels, so that a part of the wing can be at a lower height between the facade panels, because the vertical distance between the facade panels must be kept small.
  • the components of the construction are designed such that the wing can move with respect to the rail, whereby a movement is possible in the vertical direction over a minimum distance.
  • wing and the rails are not designed to be connected together, for example due to a complementary shape or by facilities for coupling means.
  • the rail is provided with a detail for a seal on the top and/or bottom edge, whereby the detail or details are at least partially above or below and around the reinforcing rib.
  • the construction also comprises a screw profile, whereby the rail and screw profile have a partially complementary shape so that the screw profile can be inserted in the rail.
  • the reinforcing rib of the wing is at least partly between the rail and each of the two facade panels located above one another.
  • a curtain wall 1 shown in figures 1 and 2 primarily consists of a post 2, made from a hollow aluminium post profile, and two rails 3, made of hollow aluminium rail profiles, that are fastened together. It goes without saying that an entire curtain wall 1 comprises a large number of such posts 2 and rails 3.
  • the post 2 and rails 3 are provided with details 5 at two edges in which seals 6 are affixed that can seal off openings between the post 2 and the rails 3 on the one hand, and a facade panel 7, for example a glass panel, on the other hand.
  • the rails 3 are provided with a nose 8, which is a double ridge 9 with a narrow groove 10 between them.
  • the nose 8 protrudes out of the rails 3 in the direction of the facade panel 7.
  • a cruciform support 11 is fastened to the post 2 and rails 3, that primarily consists of a body 12 that is fastened to the post 2 by means of bolts 13 and two wings 14 that are each fastened to a rail 3 by means of bolts 14.
  • the support 11 is made of steel, but could also be made of aluminium or another metal.
  • a facade panel rests on a wing 14 of a support 11 via a small supporting block 15, and this wing 14 in turn partly rests on the nose 8 of the rails 3, and partly rests on the post 2 via the body 12.
  • An insulator 16 is affixed in the nose 8 between two facade panels 7 located above one another, which counteracts air circulation in the space between two facade panels 7 and thereby increases the insulating properties of the curtain wall 1.
  • the transition between two facade panels 7 is covered by a clamping profile 17 of two parts screwed into the insulator 16 and the nose 8. This clamping profile 17 clamps facade panels 7 against the rails 3, so that the facade panels are well secured in the construction of rails 3 and posts.
  • the maximum vertical distance between two facade panels 7 is defined by the height H of the rails 3 in combination with the overlap, set by standards, between the clamping profile 17 and a facade panel 7 and a small clearance to prevent contact. It is undesirable here to increase the height H of the rails 3 with regard to the undesired visual impact thereof.
  • the support 11 is constructed such that only the body 12 contains holes 18 to fasten the support 11 to the post 2.
  • the wings 14 are not designed to be connected to the rails 3. The result is that the support 11 is then only fastened to the post 2.
  • the wings 14 of the support 11 are provided with a reinforcing rib 19, which extends over the length L of the wing 14 and protrudes both below and above the part 20 of the wing 14 on which the facade panel 7 rests. Due to its height A the reinforcing rib 19 provides effective resistance against vertical bending of the wing 14.
  • the wings 14 have a cross-section that has the form of a tilted T, whereby the reinforcing rib 19 forms the head of the T.
  • the rails 3 are constructed with a deepened section 21 that is located between the details 5 for seals 6.
  • This deepened section 21 provides room for the reinforcing rib 19, so that the reinforcing rib 19 has a height A that is greater than the maximum vertical distance between two facade panels 7, whereby the reinforcing rib 19 is between the rail 3 and the facade panel 7.
  • the details 5 for seals 6 fit widely around the reinforcing rib 19, so that this reinforcing rib 19 can move freely between the details 5 for seals 6, at least over a certain distance.
  • the construction is provided with an extension piece 22 that is mounted on the support 11.
  • this extension piece 22 and the support 11 are provided with holes 23 in which bolts can be affixed.
  • the extension piece can, depending on the material from which it is made, also partially act as an insulator.
  • the deepened section 21 is constructed as an undercut groove that enables a complementarily shaped aluminium screw profile 24 to be inserted there, in which the screws with which the clamping profile 17 is fastened can grip.
  • a traditional plastic insulator can be used.
