Definitions

  • the invention relates to a modular construction system of nodes and bars for the formation of space frameworks. It should be used as nodes preferably solid spherical nodal pieces and rods as round or rectangular pipe rods.
  • the invention further relates to a method for forming modular space frameworks using a modular building system of nodes and rods.
  • the rotatably and axially displaceable threaded bolt can be used only from the back of the connecting element and thus before the assembly of the connecting elements on the pipe rods due to its bolt head. Dissolves the only screwed prior to assembly of the truss sliding nut, the threaded bolt in the pipe rod can disappear, making the pipe rod unusable.
  • connection node elements and connecting rods for a space framework made of wood are known. Threaded bushes are embedded in the wooden ball and a plain bearing bush in the end of the wood rod. Before the plain bearing bush is inserted, a threaded bolt is inserted from the rear, the screw head is supported on the plain bearing bush against a coil spring. A non-rotatable pin-slot connection holds the threaded bolt slidably in the plain bearing bushing. In this case, both the sliding bearing bushing of each connecting rod end and the latter itself are each formed from two axially aligned hollow cylindrical parts. To screw in the threaded bolt, the lower part of the connecting rod end is rotated together with the threaded bolt by hand and so the threaded bolt screwed into the wooden ball.
  • the bolt can not be screwed tight in a first assembly step in the knot piece before the strut is attached, but only together with the strut. This complicates, as already stated, the assembly considerably. Attention is drawn to how difficult it will be if not only one strut is to be fastened, but several struts to be screwed close together into a ball-like knot, as is very often the case with trusses. Then with increasing assembly progress is always any already mounted strut for the insert pin in the way. Furthermore, the bolts and pockets are relatively complicated to produce rotary drilling or rotary milled parts.
  • the invention has for its object to develop a modular construction system of nodes and rods of the type mentioned, which does not have the disadvantages mentioned above.
  • the building system should consist of as few as possible and easy-to-manufacture components.
  • a space frame should be easy to build out of it and without special tools by just one person.
  • the prefabricated components that have already been delivered ready-made to the construction site should be able to be added to a space framework without elaborate adaptation measures, such as adjustment by means of driving sleeves or mounting bolts.
  • the removal and installation of a rod or rods for the purpose of renewal due z. B. damage from the outside should be made possible without depletion of the rest of the space frame tension.
  • a mere visual inspection should already allow to determine whether the threaded bolts are all screwed into their stop in the node piece.
  • the assembly should be able to take place without regard to which angle of rotation around its longitudinal axis, the pipe rods just take.
  • the system should not only be high-strength and thus meet all static tensile, compressive, torsional and shear strength requirements, but also satisfy increased aesthetic demands.
  • each pipe rod end piece consists of two longitudinally divided shell parts, one of which additionally carries a collar , which is firmly connected to a tube end and the other shell part is releasably connected to the first shell part, and wherein both shell parts each have half hollow contours for positive reception of the bolt head together with a partial shank of the bolt.
  • the production of the connecting elements is relatively simple.
  • the pipe rod end piece consists of two metal or plastic molded or injection molded parts.
  • the pipe bars themselves and the connecting bolts are commercially available.
  • the massive ball-like node piece and the threaded bolt are finished on corresponding cutting machines, the threaded bolt can of course eject a fully automatic machine.
  • attaching the pipe rod end pieces in the pipe rods is not a problem.
  • a mutual alignment with respect to their angle of rotation is not mandatory.
  • the threaded holes and abutment rings can be made in one go, so that overall the production of the system is inexpensive designable.
  • FIG. 2 shows the knot piece with threaded bolts screwed in by way of example
  • FIG. 3 shows individual parts of a pipe rod end
  • FIG. 4 shows a mounted pipe rod in a perspective view
  • Fig. 5 shows a mounted pipe rod in section and Fig. 6 a mounted prismatic space frame.
  • a spherical nodal piece 1 of solid material preferably metal or a tough plastic, depending on the expected stresses of the space frame, carries distributed over its spherical surface radial threaded holes 2 for threaded bolts.
  • the threaded holes 2 are inserted so that they can accommodate the pipe bars of a preconstructed space frame.
  • the number and distribution of the threaded holes 2 on the spherical surface of the node piece 1 is not necessarily always consistent, but depends primarily on where and how many tube bars are to be connected to each other in each node of the space frame.
  • Around each threaded hole 2 around a contact ring 3 is just turned off for the threaded bolt. This can be done for example at the same time with the introduction of the threaded hole 2.
  • a threaded bushing can be embedded in the solid material.
  • the knot piece 1 is not necessarily made of solid material, with a sufficiently massive wall thickness, which allows a secure screwed connection of the pipe bars, the node piece 1 may be made durable from two shell halves. But always it carries the threaded holes 2 for the pipe rods. Furthermore, the term spherical nodal piece 1 may not necessarily be understood to mean a spherical shape in a purely geometrical sense; it may deviate from this also a particularly regular polyhedral shape.
  • Fig. 2 shows in more detail, as already four threaded bolt 4 with a not visible here tapered threaded shank portion 4a (see Fig. 5) in the corresponding threaded holes 2 of the knot piece 1 until it stops at their investment collar 4c (see Fig. 5) with the necessary force are screwed.
  • the abutment collar 4c is formed into an upper shank part 4b with a thicker shank part diameter.
  • the pipe rod 7 as such consists of a standard commercial pipe, such as a galvanized steel pipe or CFRP pipe, which is trimmed to a certain length, which is necessary in each case for use in the respective space framework.
  • the Rohrstab- end piece 8 consists of two symmetrically longitudinally divided shell parts 9, 10, wherein in addition to the one shell part 9, a collar 11 is formed by means of which this first shell part 9 in the pipe rod 7 is frontally fastened.
  • the collar 11 is factory inserted into the pipe rod 7 to its collar flange 12 and suitably secured, for example, pressed, glued, brazed, or welded.
  • Both shell parts 9, 10 have a hollow contour 13. This is formed in the shell parts 9, 10, for example by casting, that in the assembled state of the shell parts 9, 10 of the bolt head 6 of the threaded bolt 4 with at least a portion of the upper shaft portion 4b of Rohrstab- End piece 8 is received positively.
  • the threaded bolt 4 is inserted into the hollow contour 13 of the first shell part 9, after which the second Shell part 10 placed on the first shell part 9 and is detachably connected thereto.
  • the releasable connection by means of a connecting screw 14, which connects the two shell parts 9, 10 transversely.
  • a step-shaped transverse bore 15 is introduced in the first shell part 9, which receives the screw shaft and screw head of the connecting screw 14 flush and in the second shell part 10 a threaded bore 16 for tightening the shell parts 9, 10.
  • the transverse bore 15 and the threaded bore 16 extend in front of the collar flange 12 of the pipe rod end piece 8, but still behind the bolt head 6 of the threaded bolt 4, so that this need not be pierced itself.
  • pipe rod 7 is shown in a perspective view. It can be seen the pipe rod 7, the two shell halves 9, 10 of the pipe rod end piece 8, the collar flange 12, the connecting screw 14 for the two shell parts 9, 10, the upper shaft parts 4b of the threaded bolt 4 with the open-end wrench engagement surfaces 5, the bolt heads the threaded bolt 4 and the threaded holes 2 with their izoringen 3 for the threaded bolt. 1
  • the tube rod end pieces 8 run in a frustoconical manner on the knot piece 1, but without striking the knot piece 1. This ensures that despite the relatively small spherical surface of the node piece 1 sufficiently many pipe rods 7 can connect without hindering each other. Since the threaded bolts 4 are already firmly screwed into the knot piece 1 prior to the connection of the pipe bars 7, the connection of the pipe bars 7 is no Problem. To screw in the radially further connecting screws 14 in order to assemble the two shell parts 9, 10 is due to the greater distance to the surface of the node piece 1 already sufficient space available, especially since this only a screwdriver is needed and no lever tool and the complete pipe bars 7 to the bolts 4 and thus rotate about its longitudinal axis.
  • Both pipe rod ends of the pipe rods 7 are constructed identically, the complete pipe rod 7 is thus symmetrical.
  • FIG. 5 shows a section through a connection according to the invention.
  • the threaded bores 2 are introduced radially into the junction piece 1.
  • a threaded bolt 4 is for example pre-assembled, but not yet connected.
  • Another also pre-assembled threaded bolt 4 already carries a pipe rod 7.
  • the threaded bolt 4 are screwed with their lower stepped threaded parts 4a to the stop of the investment bundles 4c to the Anlagingen 3 of the node piece 1. This is done by means of the open-end wrench engagement surfaces 5 on the upper shaft parts 4b of the threaded bolt 4.
  • the Rohrstab- end piece 8 is attached.
  • the first shell part 9 carries the collar 11, which is inserted and secured up to a collar flange 12 in the pipe bar 7.
  • the second shell part 10 is placed on the first shell part 9 and connected thereto by the connecting screw 14, which the transverse bore 15 in the first shell part 9 penetrates and is screwed into the threaded bore 16 in the second shell part 10.
  • FIG. 6 shows, by way of example, a prismatic space framework 17, constructed from the modular construction system according to the invention.
  • a closed space framework 17, for example a cantilever is set up, wherein in a nodal piece, depending on its position, three to eight tube bars converge.
  • many more pipe rods can be absorbed by their knot pieces.
  • a preferred method of assembly is as follows:
  • the factory is delivered with pipe rod end pieces 8 vorkomplettier- te tube 7 and with threaded bolts 4 precomplete knot pieces 1 to the site.
  • the number and exact length of the pipe bars 7 and the configuration of the node pieces 1 is given in accordance with a construction drawing, regularly repeating many configurations, which greatly reduces their number.
  • a fitter must place on the site only in accordance with the construction drawing the corresponding threaded bolt 4 bolt head side in the shell halves 9, 10 of the pipe rod end pieces 9 of the corresponding pipe rod 7 and secure the shell halves 9, 10 by means of the connecting screw 14. And so on. Since the upper flange and the two lower chords of the prismatic space frame 17 are composed of tube rods 7, no bulky and heavy parts are to be transported to the site.
  • the invention can be applied to modular scaffolding, mast, column, boom, dome and roof structures. It is suitable for the construction of fixed structures as well as for the construction of technical equipment and mobile machines, such as cranes, excavators, robots, etc.
