The discharging method of embodiment 4 is especially applicable for the top layer post.
By the 5th support unit 23 formed power transmission routes and the 6th support unit 24 formed power transmission routes of supporting mechanism, the load that upper strata post and first beam 15 of structural column to be unloaded 22 passed over is passed to lower floor's post of structural column to be unloaded 22 whole or in part.
A kind of discharging method for the building structural column of the present invention, each support unit not only pulling force of tension cross bar 5 is convenient to apply and control, and controls the height of a whole set of support unit by regulating the rhombus angle, can adapt to the difference that actual clear height exists.In each support unit, by change the effective length of tension cross bar 5 at the outside, tension cross bar 5 two ends rotating nut 8,5 angulations of diagonal in compression and tension cross bar become large, thereby change the whole height of support unit, and support unit and close structure are fitted.The effective length of tension cross bar 5 refers to the length between two nuts 8 on the tension cross bar 5.Then rotate a side nut, make 5 stretch-draw of tension cross bar, thereby make the rhombic supporting unit produce support force in another diagonal to up-down structure.Pulling force in the tension cross bar 5 is L, and the support force of support unit is P, and the angle between tension cross bar 5 and the diagonal in compression is θ, concerns P=Ltg θ according to equilibrium of forces.Can obtain the support force of support unit by tension cross bar 5 suffered lateral pulls, and then obtain the support force of whole supporting mechanism.Under identical support force condition, the angle between diagonal in compression and the tension cross bar 5 is larger, and the required pulling force of tension cross bar 5 is less.By regulating tension cross bar 5 pulling force control support force, produce load in the supporting mechanism position, to reach the unloading purpose.Pulling force is little in the tension cross bar 5, thereby is convenient to apply and control.The height of supporting mechanism is adjustable and arrange flexible, can use and reuse overlap support combinations more according to actual needs.The practical application effect of the adjustable supporting mechanism of this rhombus is good.
