Definitions

  • the invention relates to a space framework according to the preamble of claim 1.
  • the connecting screws are integrally connected to the spherical node body.
  • the task of the knot body described there is not only to connect certain hollow profiles to one another, it also serves to guide the liquid or gas, which is used for cooling, from the store to the customers.
  • a good connection can be made between the hollow profiles and the node elements, especially when it comes to hollow profile elements with a circular cross section.
  • this connection requires several, coordinated connecting parts, which make the accounts staff system complex and cost-intensive.
  • Another disadvantage of the known system is that it is only indirectly protected against fire or overheating. This is achieved by passing cooling medium through the hollow profiles if necessary.
  • DE-A 31 33 946 describes a supporting structure
  • DE-A 29 17 422 describes a system consisting of pipes and balls for the production of a building grid. These space trusses are connected by means of screws. However, they are not suitable for transporting liquids or gases.
  • connection between the profile bars and the knot bodies is made such that the connecting screws are brought through the opening into the interior of the knot body and then arranged in the openings provided for the connecting screws. Then the connection between the screws and the profile bars is established. Finally, the lid is tightly connected to the node body. Such a connection between the node body and the profile bars is therefore suitable for guiding a medium from one profile bar into the other.
  • node bodies are symmetrical with respect to one of their axes, and the working and connecting surfaces of the node bodies can be flat, then an even loading of the node body is ensured, and above all it is avoided that the node bodies can be deformed.
  • An expedient measure of the invention provides that the working and connecting surfaces of the node bodies are congruent with the working and connecting parts of the hollow profiles. This not only ensures optimal use of the outer surface of the knot body, it also ensures that the profiled bars are supported on the knot body over their entire working and connecting parts.
  • the node body is cup-shaped, it is expedient to design it in such a way that it has twelve working and connecting surfaces. Such nodes are most often used for flat spatial trusses. It is expedient here if the adjacent working and connecting surfaces of the node bodies form an angle of 45 °.
  • the node body is ring-shaped or tubular, then it is expedient if it has either five, six or eight working and connecting surfaces for the construction of domes and biaxially curved lattice shells. In these cases, the longitudinal central axis of the connecting rods is inclined relative to the working and connecting parts of the node bodies.
  • connection between the knot bodies and profiled bars can also be improved in such a way that the opening of the knot body is dimensioned such that the connecting screws can be inserted from the inside to the outside through openings in the knot body designed as bores.
  • Allen screws are expediently used, the heads of which are arranged in the interior of the node body.
  • a good and tight connection between the cover and the knot body can be produced in that the opening of the knot body tapers from the outside inwards and that the cover in the connection area is complementary to the knot body. It is advantageous here if the cover can be connected to the node body by means of several screws.
  • the screws can be self-tapping and can engage in embossed thread channels of the ring or tubular profile sections.
  • the cover is designed as a sprinkler system. It can be provided that the cover has a threaded bore into which a fire extinguishing system, in particular a sprinkler system, can be screwed.
  • the invention is a knot-rod system with hollow profile bars whose longitudinal central axes intersect the working and connecting parts at an angle other than 90 °, then it is expedient if the connecting screws and the heads arranged in the interior of the knot body Knot body washers are arranged that taper, the angle of inclination of the washers corresponds to the angle that the longitudinal central axes include the working and connecting parts.
  • the figures show part of a node-rod system with hollow profile rods 10, 12; 14, 16 and with hollow bodies existing knot bodies 18, 20, which can be detachably connected to the profile bars 10, 12 or 14, 16 by means of screws 22, 24, 26 and by means of which an at least partially closed, interconnectable pipe system can be produced, which can be supplied with liquid through supply and discharge or gaseous medium can be loaded.
  • the knot bodies 18, 20 are cup-shaped (cf. FIG. 1) or annular (cf. FIG. 4) and have on their outer surfaces working and connecting surfaces 30, 32 which are connected to the working and connecting parts 34, 36 of the hollow profiles 12 , 16 are tightly connectable.
  • These surfaces 30, 32 each have at least one opening 40, 42 for connecting screws 22, 24, 26, which preferably have an axial opening 50, 52, the interior of the knot 50, 52 with the interior 54, 56 of the profile bar 12, 16 connected to the knot body 18, 20 connectable breakthrough 60.62.
  • the node bodies 18, 20 each have at least one opening 64, 66, 68, which can be sealed tightly by means of a cover 70, 72, 74 which can be releasably connected to the node body 18, 20.
  • the node bodies 18, 20 are symmetrical with respect to one of their axes and their working and connecting surfaces 30, 32 are flat. These working and connecting surfaces 30, 32 of the node bodies 18, 20 are preferably congruent with the working and connecting parts 34, 36 of the hollow profiles 12, 16.
  • the cup-shaped knot body 18 shown in FIGS. 1 to 3 has twelve working and connecting surfaces 30, the adjacent working and connecting surfaces 30, 31 of the knot body 18 forming an angle of 45 °.
  • the ring-shaped or tubular node body 20 has eight working and connecting surfaces 32, 33.
  • the openings 64, 66, 68 of the node body 18, 20 are dimensioned such that the Connecting screws 22, 24 can be easily inserted from the inside to the outside through the openings 40, 42 designed as bores. 2 and 5 in particular show that the openings 64, 66, 68 of the knot body 18, 20 taper from the outside inwards and that the covers 70, 72, 74 in the connection area are designed to be complementary to the knot bodies.
  • the covers 70, 72, 74 can be connected to the node body 18, 20 by means of screws 80, 82.
  • a sealing body 84 is arranged in the connection area of the cover 70 and the node body 18.
  • a tight connection between the profile rod 12, 16 and the knot body 18, 20 is produced by sealing rings 90, 92.
  • the cover 70 has a bore 96, 98 with a thread into which a shower or a sprinkler nozzle 98, 100 can be screwed.
  • FIG. 5 also shows that hollow profile bars are provided, the longitudinal center axis of which intersect the working and connecting parts at an angle different from 90 °.
  • a washer 104 between the head 102 of the connecting screws arranged in the interior of the knot body 20 and the knot body 20, which tapers Inclination angle of this washer 104 corresponds to the angle which the longitudinal central axis includes with the working and connecting parts.
  • the annular or tubular node body 18, 20 shown in FIGS. 4 and 5 has eight outer square connection surfaces. As in the case of the cup-shaped node body (cf. FIGS. 1 to 3), the inner connection surfaces are also square in this node body. The Difference in size between the inner and outer square is compensated for by a step-like heel.
  • the bores 92 formed in the working and connecting surfaces 32 (two are provided in each case) not only enable the knot body to be connected to a rod 16 by screwing a screw in the rod left direction into a corresponding threaded channel of the rod 16 from the inside; they also allow the node bodies 20 to be connected to one another.
  • the stepped edge of the knot body also enables the connection of a cup-shaped to an annular or tubular knot element.
  • the step-shaped edge of the ring-shaped or tubular node elements can also be achieved by joining two pentagonal, hexagonal or octagonal profile strands of different width across flats. Cylindrical channels can be stamped into one of the profile strands, into which self-tapping screws engage. This eliminates the need for drilling and tapping to connect the annular knot bodies to the sealing lid.
  • the step-like edge of the knot elements enables the insertion of an octagonal disc, which not only allows the positive connection of the knot elements in the longitudinal direction of the profile, but also stiffens the ring-shaped or tubular and cup-shaped knots.
  • a closed pipeline network is created in the simplest way, in which water and others Media can be led.
  • This option is particularly important for aluminum structures, since the use of these structures is often ruled out due to the lack of fire protection.
  • the pipeline network not only enables passive fire protection through circulating water;
  • the integration of a sprinkler system in the supporting structure creates an active fire extinguishing system in the simplest way.
  • the high thermal conductivity of aluminum also enables a heater to be integrated into the structure.
  • the individual circuits can be linked in the cavity of the cup body or also of the ring-shaped node.
  • the bowl-shaped or ring-shaped design of the knot body of a supporting structure allows the roof loads to be entered directly into the upper chord profile. So that the lateral force component of these loads is not transmitted by the connecting screw of the rod and the knot, a hook-shaped element can be provided, which is arranged between the knot and the rod and hooks onto the step-shaped edge of the knot. This element also prevents the rods from twisting. If it is a knot body, the outer connection surface of which is not square, but rectangular, the knot and rod are connected by two screws. In this way, the rod is connected so that it cannot twist.
  • One of the two Screwing can be water-bearing. Together with the two lids, which seal the cavity of the node via a seal, the pipeline network already mentioned is produced.
  • FIGS. 6, 7 and 8 show that the knot bodies are regular polygons in cross section, which have threaded channels 83 for the screws 82 stamped into their interior.
