The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1～Fig. 4, a kind of large-span prestressed string space truss structure main couple high-altitude group of the utility model pair and micromatic setting comprise that two covers are separately positioned on the group of main couple 8 end upper chords two end nodes below to micro-adjusting mechanism; Every cover group comprises stable, the position-limit mechanism 1 that is arranged on main couple 8 end upper chords one end node below to micro-adjusting mechanism, below stable, position-limit mechanism 1 is provided with jack 2, jack 2 is fixed on the steelframe 3, steelframe 3 is fixed on the steel platform 4, steel platform 4 be fixed in the affixed flitch 5 of load-bearing scaffold 6 on; Above-mentioned two cover groups connect the brace 7 by arranged crosswise between the steelframe of micro-adjusting mechanism.Before the processing and fabricating said apparatus, carried out corresponding load and calculated and force analysis, to satisfy its bearing capacity and intensity.
Aforementioned stable, position-limit mechanism comprise curved plate 1-1, steel deck-plate 1-2, steel pipe 1-3, the upper end of steel pipe 1-3 is connected with the steel deck-plate 1-1 of corresponding jack 2 contacts with it, be connected with at least three curved plate 1-1 that contact with its corresponding node soffit on the external surface of steel pipe 1-3, the upper surface shape of at least three curved plate 1-3 and the underside shape of its corresponding node are adaptive.Aforementioned stable, position-limit mechanism can carry out suitable adjustment according to the specification of supported node, stressed size.Aforementioned stable, position-limit mechanism are rotary-type, can carry out the angle rotation, to avoid the main couple web member, reach spacing, stablize purpose applicatory.
For reaching the purpose of its load fine setting, present embodiment adopts jackscrew, can carry out corresponding specification adjustment according to the size of main couple joint load.And the jackscrew of all size is all very easily bought on market.
In order to ensure the stability of main couple node, steelframe 3 is designed to: the positive truncated rectangular pyramids type of outward appearance, lattice pillar.The material that adopts is angle steel and steel plate, is easy to buying, and processing and fabricating is simple.Through finite element software SAP2000 carry out that load calculates and work progress in force analysis, meet the demands.
