Definitions

  • the invention relates to a fastening arrangement with the features of the preamble of claim 1, a scaffolding with such a fastening arrangement and a fastening anchor having the features of the preamble of claim 11.
  • the document DE 10 2005 022 449 A1 proposes for this purpose to chemically anchor two fastening anchors in the subsurface, ie a masonry or concrete body.
  • the fastening anchors extend far into the insulating layer and are each extended by a spacer sleeve made of plastic.
  • the outer edge of the spacer sleeve lies in a plane with the applied on the insulating layer plaster layer.
  • On them is a console to be fastened. By means of screws, the console is fixed through holes in the console through the spacer sleeves.
  • the invention proposes a fastening arrangement for spacing fastening, as could be used in particular on the facade of an insulated building wall for fastening a scaffolding.
  • the fastening arrangement has at least two fastening anchors which can each be anchored in a substrate, that is to say, for example, a masonry, concrete body or the like.
  • a substrate that is to say, for example, a masonry, concrete body or the like.
  • fastening anchors which can each be anchored in a substrate, that is to say, for example, a masonry, concrete body or the like.
  • all, suitable for the particular subsurface types of mounting anchors come into question, so for example, chemically anchored anchor rods, spreading anchoring steel dowels, Kunststoffsp Sondübel with screw or nail and anchor for undercut holes.
  • screws, studs and the like serve as fastening anchors that are screwed or welded, for example, to a support, a plate or rail made of steel.
  • both fastening anchors are the same, but this is not absolutely necessary.
  • a spacer is arranged in each case.
  • the spacer serves to extend the fastening anchor in the direction away from the ground for the transmission of forces that act at a distance from the ground.
  • a connecting element according to the invention in each case rigidly connected to the at least two spacers.
  • the connection of connecting element and spacer can thus transmit a bending moment which acts around an axis which is perpendicular to the longitudinal direction of the spacer.
  • the connecting element may for example be plate-shaped or rod-shaped and may be connected in one piece, fixed or removable with the spacers. On the connecting element loads can be attached, the corresponding forces and moments on the mounting arrangement cause.
  • a scaffolding can be fastened to the connecting element.
  • the connecting element can also be itself part of an object to be fastened.
  • the connecting element is a console of an awning.
  • at least one spacer is pivotally connected to a mounting anchor. This has the effect that no bending moment is transmitted between the spacer and the fastening anchor about an axis acting perpendicular to the longitudinal axis of the fastening anchor.
  • a transverse force on the connecting element only transverse forces which can be transmitted close to the ground act on the fastening anchor, as a result of which the bending load on the fastening anchor is considerably reduced compared with the known prior art.
  • any type of moment joint could be used, such as a universal joint.
  • Ball joints have the advantage of a flat system with a small size. This allows the transmission of high transverse but also tensile forces through the ball joint with a total of small cross-section.
  • plastic instead of metal can be used, which makes the en Jardinenden components inexpensive and geometrically flexible designable.
  • Plastic also has the advantage over metal of less heat transfer. This allows the ball joint simultaneously for thermal separation serve between mounting anchor and spacers, which in particular heat losses are reduced.
  • the ball joint preferably has a rotary body which is mounted in two shells.
  • the shells have at least partially spherical bearing surfaces. However, they need not be bowl-shaped in the strict sense, but may, for example, be annular.
  • the shells are arranged one behind the other in the axial direction on the fastening anchor and in particular so that the bearing surfaces face each other and the rotational body is received between them. As a result, the rotational body can be tilted relative to the fastening anchor.
  • Such an arrangement has the advantage that the combination of fastening anchor and spacer can be built very slim despite ball joint.
  • the body of revolution could be rigidly mounted on the attachment anchor and the spacer bearing surfaces, but this would require larger cross-sections, which would have to be recessed, for example, in an underground covering insulating layer.
  • the rotary body mounted so movably on the fastening anchor preferably has a connecting means for the spacer in the area between the shells.
  • connecting means such as a Verklipsung, bonding, a bayonet lock or a compression, in question.
  • a thread offers the possibility of simple assembly and disassembly. Especially the possibility of disassembly is important when it comes to no permanent attachment, as is the case with scaffolding in the rule.
  • a spacer which is arranged in the region of the insulating layer, removed and the corresponding recess in the insulating layer are closed. If necessary, even the fastening anchor can be removed again.
  • the rotary body has a passage opening.
  • the passage opening widens from the center, in each case toward the outside, in particular substantially in the form of a double cone.
  • a Zentrier joskeit in the middle of the passage opening is created during assembly and the rotational body receives limited mobility, for example on a threaded rod.
  • the ball joint is rotationally fixed with respect to rotation about the longitudinal axis of the attachment anchor.
  • the invention proposes that the rotary body in the region of the passage opening has a rotary driving means, for example a tongue and groove connection between the rotary body and the remaining fastening anchor.
  • the spacer is at least partially tubular.
  • This has the advantage that with little use of material, a very large bending moment can be transmitted, as may occur due to the support of transverse forces on the fastening anchor near the connecting element.
  • the spacer tubularly comprises the ball joint on the fastening anchor.
  • the invention also proposes that the connecting element is at least partially tubular and the connecting element is connected to the spacers via pipe connector. As a result, can be used on inexpensive, stable standard components, such as so-called superior cross pieces or turning pieces, which are known from the scaffolding.
  • FIG. 1 shows a perspective view of the fastening arrangement according to the invention
  • Figure 2 shows the region of the connection of fastening anchor and spacer in a partially sectioned view
  • Figure 3 shows the same area without the spacer in a partially sectioned view
  • Figure 4 shows the ball joint of the fastening anchor according to the invention in a perspective exploded view.
  • the fastening arrangement 1 shown in Figure 1 is used to attach a scaffolding, not shown, to a facade 2 of a building.
  • the facade 2 has an insulating layer 3, for example made of polystyrene, which is applied for thermal insulation on a substrate 4 made of concrete. Due to the low strength of the insulating layer 3, the attachment can not take her, but must be done in the background 4.
  • the fastening arrangement 1 has two fastening anchors 5 with a threaded rod 6, which are each chemically anchored in a borehole 7 in the substrate 4, that is, they are surrounded by a hardened composite 8. At their projecting from the borehole 7 ends have the fastening anchors 5 each ball joints 9, which will be discussed in more detail below with reference to Figures 2 to 4.
  • the ball joints 9 establish the articulated connection of the fastening anchors 5, each with a tubular spacer 10.
  • the spacers 10 project through the insulating layer 3 through to the front of the facade 2 and are each rigidly connected to a tubular connecting element 11.
  • the rigid connection of spacer 10 and connecting element 11 by means of a pipe connector 12 in the form of a superior crosspiece.
  • the connecting element 11 By the connecting element 11, the two spacers 10 are interconnected.
  • To the connecting element 11 by means of terminals (not shown) or the like continue to be grown objects, such as air conditioning equipment, balconies, stairs and the like.
  • the connecting element 11 itself could be part of an object to be fastened, in particular part of a framework.
  • a transverse force Q ie a force directed perpendicularly to the longitudinal extent of the fastening anchor 5 acts on the connecting element 11, this is transmitted to the spacers 10 via the rigid connections of the pipe connectors 12 and through the ball joints 9 as pure transverse forces Qi and Q 2 the fastening anchor 5 transmitted. Since the ball joints 9 are arranged near the base 4, this results in a minimal bending moment in the respective fastening anchor 5, which can be dimensioned correspondingly small. Since the pipe connectors 12 bend minimally due to the bending moment acting in them can, recesses 13 in the insulating layer 3 in diameter are slightly larger than the spacers 10.
  • FIGS. 3 and 4 show the region of the articulated connection of spacer 10 and fastening anchor 5 in more detail.
  • the base 4 is not shown, in addition to the spacer 10 in FIGS. 3 and 4, and also not the threaded rod 6 in FIG. 4.
  • the ball joint 9 has a rotary body 15 made of plastic, which has the basic shape of a ball. It is centered except for a through opening 16, which extends from the center, each slightly tapered outwards. Parallel to the passage opening 16, a thread 17 is arranged on the outside. On this thread 17, the spacer 10 is screwed. The thread 17 thus serves as a connecting means 18 to the spacer 10.
  • the spacer 10 has for this purpose at its the fastening anchor 5 end facing an internal thread 19.
  • the rotary body 15 is arranged between two annular shells 20 on the threaded rod 6.
  • the threaded rod 6 penetrates the shells 20 and the rotary body 15, respectively.
  • the shells 20 each have mutually facing, spherically curved bearing surfaces 21 for holding the rotary body 15.
  • These bearing surfaces 21 6 acting forces are transmitted between the spacer 10 and the threaded rod. They also cause that the rotary body 15 can pivot about an axis perpendicular to the longitudinal extent of the threaded rod 6 axis.
  • no rotational movement can take place about the longitudinal axis of the threaded rod 6, since the rotational body 15 has rotational driving means 22 in the form of four notches 23 distributed over the circumference in the region of the passage opening 16.
  • each of these notches 23 engages a bead 24 of a receiving socket 25 made of plastic.
  • the notches 23 and beads 24 together form a tongue and groove connection.
  • the receiving bushing 25 tightly surrounds the threaded rod 6 and is so long that it penetrates and receives the two shells 20 and the rotary body 15.
  • the receiving socket 25 pivot.
  • the receiving socket 25 is divided by a wide slot 26 into two tongues 27 (see FIG. 4) so that one of the two shells 20 can be pushed over the beads 24 during assembly by slightly compressing the tongues 27.
  • the receiving socket 25 has a circumferential collar 28. It serves as a stop for the base 4 facing shell 20. In the preparation of the fastening assembly 1, the threaded rod 6 is pushed so far into the hole 7 until the collar 28 is present on the substrate 4 (see Figure 1).
  • the female connector 25 is made of plastic, it also acts as a spring and prevents the shells 20 from being stretched too much against each other, thereby hindering the pivotal movement of the rotary body 15. Due to the long lever of the spacer 10, however, it is sufficient for the function when the movement can be made sluggish.
  • the fastening anchor 5 could, for example, have a frame anchor made of plastic, which accommodates the receiving socket 25 with its shank (not shown).
  • the arrangement of three fastening anchors 5 would be possible, especially if additional parallel to the facade 2, but perpendicular to the transverse force Q acting forces to be removed (not shown).
