Therefore, exemplary term D score can comprise upper and lower both orientation. Device can otherwise position (90-degree rotation or be positioned at other orientation), relatively illustrates used herein of space correspondingly to explain.
As shown in Figure 1-2, FAST telescope collar tie beam lattice column structural system includes collar tie beam 1 and some lattice columns 2; Wherein, collar tie beam 1 is space truss structure, collar tie beam 1 inner ring diameter 500.8m, high 5.5m, wide 11m, is made up of round steel pipe and welding special-shaped component, and round steel pipe and welding special-shaped component are connected by solder sphere and gusset plate; The lower edge of collar tie beam 1 is provided with several nodes, and collar tie beam bears, by node, the dynamic load that main rope net is transmitted through, and collar tie beam 1 is by a located some lattice column 2, and lattice column 2 falls within lattice column basis.
In order to ensure that bidirectional sliding support pushes up center generally within lattice column 2 after cable stretching completes, when collar tie beam 1 designs, the radius of a circle at collar tie beam 1 place is extended out 100mm. When cable stretching to benchmark sphere state, collar tie beam 1 produces certain radial deformation, it is possible to meet the bearing center, top generally within lattice column 2.
Being provided with two two-way slip support abutments often organizing lattice column 2 capital, by collar tie beam 1 hoop and radial constraint release, only provide the vertical support of collar tie beam 1, the use of this bearing reduces the highly non-uniform impact on structure integral rigidity of lattice column 1; The base 3 of bidirectional sliding support is fixing with described lattice column 2 to be connected, and the footstock 4 of bidirectional sliding support is fixing with collar tie beam 1 to be connected; Being provided with a two-way sliding axle 5 between base 3 and footstock 4, the lower end of Bidirectional slide axle 5 is seated in the chute on described base 3, and the diameter of the lower end of Bidirectional slide axle 5 is less than the internal diameter of chute; The upper end of Bidirectional slide axle 5 is connected with footstock 4 clamping, and the junction of the two is provided with a steel hemisphere 6; Because the diameter of lower end of Bidirectional slide axle 5 is less than the internal diameter of chute, thus Bidirectional slide axle 5 can transverse shifting, and the setting of steel hemisphere 6 in the plane at chute place, moving radially, for Bidirectional slide axle 5, the condition of creating; Based on the impact of variations in temperature, between collar tie beam 1 and lattice column 2, slip support abutment is set, when variations in temperature, by the Relative sliding release temperature stress of collar tie beam 1 with lattice column 2, improves structural-load-carrying capacity.
Owing to collar tie beam 1 is supported on lattice column 2 top by slip support abutment, and peripheral in encorbelmenting attitude, so arranging anti-pulling device, it is possible to effectively prevent collar tie beam 1 from departing from lattice column 2, and can also play and limit the effect that sliding therebetween is excessive; Anti-pulling device is made up of inverted T shape resistance to plucking bar 7 and spacing otic placode 8, and the upper end of inverted T shape resistance to plucking bar 7 is fixed on collar tie beam 1, and the lower end of inverted T shape resistance to plucking bar 7 is arranged in spacing otic placode 8; The lower end of inverted T shape resistance to plucking bar 7 can in spacing otic placode 8 transverse shifting setpoint distance; Spacing otic placode 8 is fixed on the capital of lattice column 2.
