Definitions

  • the invention relates to an outer wall of a building with a facade arranged in front of it.
  • each of the profiles is connected to a substructure at several spaced-apart points in a weight-bearing manner, which in turn is supported by the outer wall.
  • connecting fittings are preferably used for the connection between the profiles and the substructure which extend on the profiles only on the side of the lateral surface which faces the substructure.
  • the connecting fittings are typically designed in two parts, with one fitting part being anchored to the substructure and the second fitting part to the profile, and the two fitting parts can be hooked to the substructure-side fitting part by moving the profile-side fitting part downwards.
  • DE 20218592 U1 shows an example connecting fitting.
  • the EP1764447B1 shows a connecting fitting for connecting a lateral surface side of a vertically running wooden profile ("post") with the front side of a horizontally running wooden profile ("bar”), which is to be supported by the vertically running profile.
  • the connecting fitting has two fitting parts designed as horizontally running profile sections, with one fitting part on the lateral surface side of the vertically running wooden profile is attached by screws and the second fitting part is attached to the front side of the horizontally running wooden profile by screws.
  • To connect the two fitting parts to each other first a profile wall of the fitting part on the horizontal wooden profile, which forms a hook extension that is open at the bottom, is hooked to a profile wall of the fitting part on the vertical wooden profile, which forms a hook extension that is open at the top. Then a screw is screwed into a channel that runs horizontally between the two profile walls, whereby the two fitting parts are braced against each other and thus rigidly fixed to each other with regard to all degrees of freedom.
  • the EP4067594A1 describes a two-part connecting fitting which is designed to anchor the front face of a horizontally running beam to be supported to the outer surface of a vertically running beam. Both fitting parts are in turn profile sections.
  • One fitting part is designed with a groove with a T-shaped cross-sectional area and the second fitting part with a projection in the form of a T-profile. To connect, the projection is inserted into the groove in the direction of the profile and then a screw is screwed into two remaining channels, the outer surface of which is each formed by the surfaces of both fitting parts, which is in threaded engagement with both fitting parts.
  • the profile directions of the two fitting parts and the direction of the screws run vertically, i.e. parallel to the direction of the greatest force to be transmitted.
  • fitting parts are divided into individual pieces which can be plugged together in the vertical direction.
  • the screws to be screwed into the channels then extend in one piece over the total length of all individual pieces.
  • the object underlying the invention is to carry out the weight-bearing anchoring of vertically running profiles of a facade at several vertically spaced anchoring points on a substructure in such an improved manner compared to the construction methods discussed that the load transfer is better distributed across all anchoring points.
  • the surfaces of the two fitting parts facing each other are designed as the lateral surface sides of a vertically aligned profile and can be pushed into each other by a vertical relative movement, their vertical relative position to each other can be freely adjusted over a wide range.
  • the vertical relative position between the two fitting parts is only fixed when the threaded bolt is screwed into the channel between the two fitting parts.
  • the two fitting parts can preferably be hooked into each other by a relative movement in the vertical direction against relative movement in the horizontal direction. In addition or as an alternative to this, they can also be hooked into each other by a relative movement in the horizontal direction, so that they are held together by a snap connection.
  • Fig.1 and Fig.2 show an outer wall 1, which indirectly supports vertically running wooden profiles 2, which are parts of a facade located in front of the outer wall 1.
  • the wooden profiles 2 are connected by connecting fittings 3 to a substructure, which comprises horizontally running slats 4, which are rigidly anchored to the outer wall 1 via connecting parts 5.
  • the connecting fittings 3 are each made in two parts; a threaded bolt 8 is used to fix the two fitting parts 6, 7 of the connecting fitting 3 to one another.
  • each of the vertically extending wooden profiles 2 is indirectly connected to the outer wall 1 at several connection points spaced apart from one another in the vertical direction.
  • FIG.3 the structure of the connecting fitting 3 is clearly visible. Screws 9, 10 and threaded bolts 8 are shown in a simplified manner using dash-dotted lines.
  • the connecting fitting 3 comprises two fitting parts 6, 7.
  • One fitting part 6 is anchored to the horizontally running slat 4 by means of screws 9.
  • the screws 9 run through screw through-holes in the fitting part 6 and are in threaded engagement with the material of the slat 4.
  • the fitting part 7 is anchored to the vertically running wooden profile 2 by means of screws 10, in that the screws 10 pass through screw through-holes in the fitting part 7 and are in threaded engagement with the material of the wooden profile 2.
  • the fitting parts 6, 7 touch each other.
  • the contact surfaces of the fitting part 6 with the fitting part 7 are the lateral surface sides of a first vertically extending Profile and the contact surfaces of the fitting part 7 with the fitting part 6 are designed as jacket surface sides of a second profile running in the vertical direction. Regardless of whether the two fitting parts themselves are profile sections, the contact surfaces of the two fitting parts to one another are all vertically aligned surfaces, as if they were each part of the jacket surface of a vertically running profile piece.
  • the two fitting parts 6, 7 can be pushed into one another by a relative movement in the vertical direction such that profile projections 11, 12 of one fitting part 6 or 7 protrude into profile grooves 13, 14 of the other fitting part 7 or 6 and also protrude into an undercut area 15, 16 of the respective profile groove 13, 14, so that relative movement of the fitting parts 6, 7 to one another in all horizontal directions is blocked by a form-fitting connection.
  • the fitting parts 6, 7 together delimit a channel 17 which, like the mentioned lateral surface sides, runs in a vertical direction.
  • Part of the lateral surface of the channel 17 is a surface of one fitting part 6 and another part of the lateral surface of the channel 17 is a surface of the second fitting part 7.
  • a threaded bolt 8 is screwed into the channel 17, the external thread of which is in threaded engagement with a nut thread, the grooves of which run in the boundary walls of the channel 17 in both fitting parts 6, 7.
  • the two fitting parts 6, 7 only touch each other on vertical surfaces. Compared to other designs, this enables easier production of the fitting parts 6, 7 and there are fewer restrictions when pushing the fitting parts 6, 7 into one another.
  • undercut area refers to a cross-sectional area of a profile groove which is shaded from part of the opening area of the profile groove by a wall that laterally borders the profile groove. It is also very often the case that in this cross-sectional area of the profile groove the width of the profile groove increases with increasing groove depth.
  • the fitting parts 6, 7 are made of aluminum and the threaded bolt 8 has a self-tapping thread. This combination achieves good strength and durability and it is not necessary to cut a nut thread on the fitting parts 6, 7 in advance.
  • the two fitting parts 6, 7 of the connecting fitting are identical to one another.
  • the two fitting parts 6, 7 are rotated relative to one another by 180° around a vertical axis and slightly offset to the side.
  • advantages are achieved compared to different designs, especially in terms of procurement and storage logistics and in terms of the costs for manufacturing tools.
  • each of the fitting parts 6, 7 must have both a profile groove 13, 14 and a profile projection 11, 12, which is dimensioned such that it can be inserted into the profile groove 13, 14 of another, but identically designed fitting part 6, 7.
  • the fittings 6, 7 are sections of an extruded aluminum profile.
  • Aluminum is advantageous for the intended purpose in terms of its material properties.
  • the extrusion manufacturing step makes it easy to realize the complexity of the profile shape and the manufacturing process becomes very economical for series production.
  • the fitting parts 6, 7 have several profile grooves on the side with which they are in direct contact with the horizontally running slat 4 or the wooden profile 2, so that they only contact the slat 4 or the wooden profile 2 with the free end faces of the walls that laterally delimit these profile grooves. Compared to a full-surface contact, this improves the drying of moisture, which increases the durability of the wooden parts. The drying of moisture is also improved compared to otherwise comparable designs in which fitting parts with contact surfaces that have a horizontally running profile are in contact with other parts.
  • the parts of the substructure anchored to the outer wall 1 to which the wall-side fittings of the connecting fittings are directly anchored do not necessarily have to be horizontally running slats 4 as shown in the drawings. They can also be horizontally running metal profiles, for example, or even spacers made of a solid material placed only at certain points to the outer wall 1. Depending on the design of these parts of the substructure, the wall-side fittings of the connecting fittings can also be mounted to these parts in a way other than by screws that run through through holes in them.
  • those material webs on which the two fitting parts 6, 7 are hooked together are somewhat flexible in horizontal directions so that the hooking of the two fitting parts 6, 7 to each other can also be produced in the manner of a known plug connection by moving the two fitting parts 6, 7 towards each other in a horizontal direction, normal to the plane of the outer wall 1, with some effort, so that projections of one fitting part are pushed into recesses in the other fitting part, whereby the walls on which the two fitting parts touch each other are elastically bent somewhat around horizontal axes until projections of one fitting part are engaged in recesses of the other fitting part.
  • Fig. 3 The design of the fitting parts 6, 7, which can be seen in detail, makes it possible for the fitting parts 6, 7 to snap into one another.
  • fitting parts 6, 7 can be plugged into one another and hooked together by means of a horizontal relative movement in the manner of a snap connection, no vertical displacement of the wooden profiles is required for the installation of the wooden profiles 2 on the outer wall 1. This is quite advantageous because in some buildings there is sometimes not enough space for such a vertical relative movement due to certain projections.
  • the screws used for this purpose are preferably equipped with a self-drilling tip and self-tapping thread. If there is very little space next to the wooden profiles, a known angle extension can be used for the screwing tool, i.e. an angle gear which is arranged between the screwing device and the screw and deflects the plane of the rotational movement required for screwing in the screw by 90°.
