2, be that " node body " is superior to " connector " again
The node design is the key technology of aluminium alloys space truss structure; The node body of aluminium alloys rack of the present invention has avoided the big technical requirements of aluminium alloys welding difficulty high; Welding aluminum alloy exists the heat affected zone strength of materials to reduce and is not easy to plant produced and the defective of site operation difficulty, is innovations and breakthroughs of aluminium alloys space truss structure.
The inventor conscientiously contrasted denomination of invention for " space frame connection node arrangement " (inventor: GA Reynolds, DR Haake this, the GN gram carries this; Publication number is CN101529027A) disclosed " connector " plurality of proposals; Think that " node body " that we invented has tangible difference with " connector ", more is superior to " connector ".
(1) invention of " connector " is a movable armature that supplies to be used for the movable support armature of the curved surface reflector of Electromagnetic Launching and be used for the curved surface solar sail.These " armatures " not only the field is different with " civil engineering ", and the load magnitude that it bears, its rigidity of structure, intensity and reliability, degree of safety all are incomparable.Some place of the invention of " connector " possibility is similar with civil engineering in other words, but can not copy mechanically from essence.
The node body of aluminium alloys space truss structure of the present invention is to conceive, design according to field of civil engineering bearing net shelf structure fully, satisfy structure, intensity, rigidity and distortion etc. and require.
(2) connector is exactly will be firmly and connect the rod member that intersects at node easily, and there is open defect in the linkage function of " connector " of publication number (CN101529027A) invention.Fig. 3 of its Figure of description and Fig. 4 have represented the structure and the body of basic " connector " of this invention; The mutual angle of central plane between 35 and 36 is some angle; And 27 rod members are when bigger than 37,38 rod member sections (the often big many web member sections of crossing of chord member section in space truss structure); Situation shown in this explanation accompanying drawing 10 will appear in " connector ": for the cross section centre of form axis of three rod members that guarantee to intersect at same node intersects at a bit; Form concurrent force system, then be used for just possibly can't the installation of shear pin that 27 rod members are connected with its place groove, bar 27 possibly can't be connected with " connector ".There is defective in " connector ", is to receive the cross dimensions that " angle " size and institute connect rod member to retrain.
Fig. 6, Fig. 8 and Figure 10 of the Figure of description of publication number (CN101529027A) expressed " connector " other several schemes again; A common problem is also all arranged; A termination or two terminations of passing the shear pin in hole 72 have exactly got in the other groove; This has just caused the inconvenience of construction and installation, and rod member is installed the interference of fighting each other, if it is just more inconvenient to adjust installation.
" the node body " of body node aluminium alloys space truss structure of the present invention; Regardless of being planting plate or planting rod-type; Perhaps hybrid node body can both satisfy X, Y, three directions of Z and intersect at (comprising positive and negative direction) rod member of same node on your marks neatly, and there all have enough positions to add respectively with bolt or riveting bolt to be fastening, do not receive " angle " and the influence that intersects at the cross dimensions of node rod member; Can guarantee that each the bar cross section centre of form axis that intersects at node intersects at a bit; Form concurrent force system, and guaranteed that every rod member and being connected of node body are independent separately fastening, do not disturb mutually.
(3) read the full text of " connector " manual; Wherein whole " connector " schemes have been studied; For civil engineering load-carrying members the space truss structure of large span (especially for), the solid thickness between these " connector " bottom lands is too thin, and the shear pinhole of 77,79 cell walls of connector is because the limiting holes position of connection request is higher; Under the effect of civil engineering structure press rods, there is cripling hidden danger.The node of Figure 29, Figure 30 and Figure 31 " connector " has caused " tubulose chord member " 131 eccentric forces, and connects with screw, is insecure to the civil engineering load-carrying members.For needs easy for installation " connector " are had to shear pin and clamping keeper as securing member, and this securing member the civil engineering load-carrying members be equally dangerous reliably.It is thus clear that " connector " bears the function of the node internal force of civil engineering load-carrying members is obviously not enough.
" the node body " of body node aluminium alloys space truss structure of the present invention; Its structure has guaranteed that the power bang path of rod member, bolt and node body is clear; Each force-summing element work internal force character of rack (drawn, pressurized or cut) all comes into plain view; For structural analysis provides the mechanical model of standard, the professional carries out the design of rod member and node body and bolt by the civil engineering related specifications, just can guarantee space truss structure each force-summing element structure requirement, requirement of strength and rigidity requirement; Guarantee node and rod member co-operation, guarantee the reliable and safety of total system.
(4) invention of " connector ", it is elongated requiring some rod members, is not easy to the architectural image design of structure.Its Figure of description 13 to accompanying drawing 23 has been told about DLG structure installation process and step, this shows it and installs both lack of standardization also inconvenient.
Body node aluminium alloys space truss structure of the present invention does not require elongated rod member, is convenient to architectural image and the slope is looked in draining.The structure of " body node " has guaranteed that the standard of rack installation, fully can be according to the kinematic analysis that forms how much invariant space systems with convenient, and the mathematical law and the principle of " not point of three links fixed space of coplane " are carried out installation.
3, body node aluminium alloys space truss structure; Its all rod members and node body all are to have made full use of the aluminum alloy materials good moldability, characteristic easy to process, and extruding or punching press are made; Rod member, node body can standardize, standardization; Can realize factory mass production, on-site consolidation, installation then, quality is more guaranteed.
