Definitions

  • the invention relates to a node connection for rod structures with more than two rods connected in a node, in particular of steel structures, the rods of which are designed as round tubes, the ends of the round tubes converging to a node being able to be fastened to a node piece by means of screw connections arranged in the tube axis.
  • the round tubes which act as rods, end on welded-on truncated cones with an axial bore.
  • a screw bolt protrudes through the bore, which is supported with its head inside the tube on the truncated cone and can be screwed into the bore of a knot piece made of solid material with its thread arranged at the front end.
  • a pipe or sleeve part is arranged, through which the screw bolt with its shaft passes. The sleeve part is connected to the shaft of the bolt in such a way that the shaft slides in the sleeve part, but cannot rotate relative to it.
  • the screw bolt By turning the sleeve part, the screw bolt can be rotated and thus the screw connection between the round pipe and the node piece can be made or loosened.
  • the node connection described has many disadvantages. It is expensive because of the large number of metal parts to be processed.
  • the welded connection between the round tube and the truncated cone is a weak point and the strength of the round tubes cannot therefore be exploited.
  • the high-strength bolts themselves are subject to notch stresses and do not create a rigid, but to a certain extent an articulated connection between the bars and the knot parts, since their core cross-sections act as flow joints when the bars are buckled. It must be full, up to the thread at the front end of the screws bolt-sufficient buckling length must be taken into account when dimensioning the bars.
  • the inherent rigidity of the framework is low.
  • the invention has for its object to provide a rigid node connection. Without weakening the more than two rods connected in a node and without the disadvantages mentioned and with less manufacturing effort.
  • the invention consists in a knot connection of the type described in the introduction that the ends of the round tubes have an external thread without weakening their cross-section and bending rigidity, the core diameter of which is at least as large as the outer diameter of the round tubes and that on this external thread a pushable or rotatable union nut can be screwed with its internal thread, the union nut also being screwable to the node piece.
  • the cavities of the round tubes which can be communicated via the node pieces, are filled with liquid, e.g. Water with the addition of anti-corrosive and possibly anti-freeze and the use of the liquid for heating, cooling and / or extinguishing in the event of fire, storage of solar heat or the like.
  • the union nut is with the front Ren section of their internal thread screwed onto a corresponding external thread of the node piece.
  • a sealing ring possibly acting as a cross-section-restricting throttle (orifice) in the gap, is arranged between the ends of the round tube and the section of the node piece which has the external thread and which influences the flow through the tube system formed by the round tubes.
  • the union nut with an external thread provided on it can be screwed into a corresponding internal thread of the node piece, the internal thread and the external thread of the union nut being arranged with the same pitch and concentrically.
  • the internal thread and the external thread of the union nut are preferably arranged along the same longitudinal section, the round tubes connected to form a knot extending into the knot piece.
  • the union nut can expediently be designed as a sleeve with a helical, wavy cross section.
  • the sleeve nut designed as such a sleeve expediently has an outwardly radially projecting ring at the rear end which, in the case of a liquid-filled rod structure, presses via an outer sealing ring against the end of the section of the node piece formed with the internal thread and via an inner sealing ring between the Seals union nut and the round tube.
  • the union nut with internal and external threads arranged along the same longitudinal section can also be designed as a spiral (screw spiral), with - in the case of a liquid-filled rod structure - the space between the spiral windings in the area in which the round tube extends into the node piece, by a sealing compound can be filled.
  • the union nut with internal and external threads arranged along the same longitudinal section can also be used as a sleeve with a recess, e.g. cast spiral (screw coil) be formed.
  • the cross section of the spiral can also be composed of two differently profiled wire halves.
  • the knot pieces are hollow and have openings which run through along the axes of the round tubes adjoining them.
  • the openings of the node pieces expediently have a diameter which is at least equal to the inside diameter of the round tubes.
  • the external thread can be at the ends of the round tubes by plastic deformation, e.g. Pressing, upsetting and / or rolling.
  • the external thread can, however, also be cut into the ends of the round tubes which are thickened by upsetting.
  • a framework with node connections according to the invention is advantageously communicating with a liquid, e.g. Water, filled and connected to a liquid circuit.
  • a liquid e.g. Water
  • the node pieces and / or the round tubes can be designed with a valve which e.g. opens in the event of a fire due to overpressure and / or overtemperature, which means that, like in a sprinkler system, the source of the fire or the framework can be sprayed with water and the resulting flow in the pipe cools the pipe wall.
  • FIG. 1 a rod structure in the form of a typical two-layer space frame, which consists of node pieces 1 and rods formed by round tubes 2, is shown in simplified form.
  • the knath pieces 1 and the round tubes 2 form a communicating fluid system with their cavities.
  • the liquid system is connected via - at the corners of the space frame - flow lines 3 and - in the middle of the space frame - return lines 4 to a liquid circuit in which a liquid container 5, a branch valve 6 and a pump 7 are located. Via a bypass line leading from the branch valve 6 to the pump 7, a heat exchanger 8 serving for heating, cooling or solar energy generation can be charged.
  • the pump 7 can be operated via a heating control and in the event of a fire via a fire alarm system or by a float switch in the event of water loss by opening one of the temperature and pressure-dependent valves in the network. Losses in the liquid system can be supplemented from the local water supply network via an automatic valve 9 controlled by the level of the liquid container 5. Water with the addition of a corrosion inhibitor and an antifreeze can be used as the liquid.
  • FIG. 2 shows one of the node pieces designated 1 in FIG.
  • Each of Figures 3 to 6 shows one connected to the node piece End of a round tube 2, which has an external thread 10.
  • the external thread 10 of FIG. 3 is formed by pressing, the external thread 10 of FIG. 4 by upsetting and rolling or by cutting into the pipe end that has previously been upset.
  • the external thread 10 visible in FIG. 5 is produced by cladding on the end of the tube 2.
  • the external thread 10 is welded onto the end of the round tube 2 in the form of a spiral (helix) made from profiled wire, for example by resistance pressure welding.
  • the core diameter d 1 of the external thread 10 is at least as large as the external diameter D of the round tube 2 and the tube cross section is not weakened.
  • FIG. 7 shows a cross-section of a node connection on a larger scale. It can be seen how the end of a round tube 2, which is provided with an external thread 10, is fastened to the node piece 1; on the external thread 10 is a, via the round tube 2 slidable (scrapable) union nut 11 screwed with its internal thread 12. The union nut 11 is screwed simultaneously with the front section of its internal thread 12 onto a corresponding external thread 13 of the node piece.
  • a sealing ring 14 is arranged in the gap between the ends of the round tube 2 and the section of the node piece 1 which has the external thread 13.
  • One of the sealing rings 14 visible in FIG. 7 is designed as a cross-sectional constricting throttle for influencing the system flow.
  • a valve connected to the node piece 1 is indicated, which can serve for ventilation or can be designed as an overpressure or overtemperature valve and is shown in more detail in FIG.
  • FIG. 8 also shows another embodiment of the node connection according to the invention on a larger scale, with two union nuts 16 and 17 being used.
  • the union nut 16 or 17 is screwed with an external thread 18 or 19 provided on it into a corresponding internal thread 20 or 21 of the node piece 1.
  • This with 22 or 23 designated internal thread and the external thread 18 or 19 of the union nut 16 or 17 are arranged with the same pitch and concentrically and along the same longitudinal section.
  • a particularly firm connection results from the fact that the round tubes 2 connected to form a knot extend into the knuckle piece 1.
  • the union nut 16 visible in FIG. 8 is designed as a sleeve with a screw-like, wavy cross section. It has a ring 24 projecting radially outwards at its rear end. The ring 24 presses via an outer sealing ring 25 against the end of the section of the male piece 1 formed with the internal thread 20. In addition, an inner sealing ring 26 seals between the internal thread 22 of the union nut 16 and the round tube 2.
  • the union nut 17 shown in FIG. 8 above is designed as a spiral (screw coil). After screwing the union nut 17, which is designed as a spiral, into the space between the internal thread 21 of the male piece 1 and the external thread 10 of the round tube 2, the space between the spiral windings of the union nut 17 has been filled by injecting a sealing compound 26.
  • FIG. 9 shows a further exemplary embodiment of a union nut 27, which is designed as a sleeve with a spiral (screw spiral) 28 cast into it.
  • the cross section of the spiral 28 can also be composed of two differently profiled wire halves.
  • the node pieces 1 are hollow and are formed with openings 30 extending along the axes of the round tubes 2 adjoining them.
  • the openings 30 have a diameter which is at least equal to the inner diameter d of the round tubes 2.
  • a valve 15 connected to a round tube 2 is shown in more detail in FIG.
  • a valve tube 31 is screwed into the round tube 2 and contains a valve body 33 loaded by a compression spring 32.
  • the compression spring 3 2 presses at the other end onto a fusible link plate 34, which opens the way for the compression spring 32 and valve body 33 from a correspondingly high temperature, so that the water can flow out through the valve tube 31 at the top.
  • the valve tube 31 also has side openings 35 through which the water can escape not only in the case of the melting of the plate 34, but also when the pressure in the liquid system takes on such a high value that it presses the valve body 33 against the force of the compression spring 32 pushed up to the openings 35.
  • a restrictor (orifice) which narrows in cross-section and is inserted into the round tube 2 is designated 36 and replaces the sealing ring 14 of FIG. 7 acting as a restrictor in this embodiment
  • the node connection according to the invention can be used with advantage for all types of frameworks, in particular for spatial frameworks, multi-belt truss girders, truss girders, barrels and trusses, single and multi-layer truss domes, truss framework domes, bar grate and surface structures.
