The present invention will be explained in more detail below.
(1) Before using, the utility model discloses strutting arrangement initial state is all in the uncontracted state for all vertical telescoping device, and vertical telescoping device stretches out promptly and makes elasticity stem and rigidity stem all be in the support state, can play rigidity stem and elasticity stem all be in the state that the internal force is zero.
(2) The steel structure is supported on the top plate of the supporting device, and the pressure of the steel structure fulcrum is transmitted to the foundation through the supporting device and the supporting frame body. Because the elastic core column has elastic deformation capacity, the elastic core column quits working instantly, only the rigid core column bears pressure, the supporting device is in a rigid supporting state, and vertical deformation is not generated.
(3) The vertical telescoping device of the lower part of the rigid core column is adjusted to be in a contraction state when the process is needed, the rigid core column is withdrawn from the supporting state, the elastic core column starts to enter the supporting state, and the whole supporting device is in an elastic state. Because the steel structure body has certain rigidity, micro deformation is generated, and the pressure applied to the elastic core column is smaller than the supporting pressure at the beginning.
(4) The vertical telescopic device at the lower part of the elastic core column can be further adjusted to be in a contraction state according to requirements, part of the elastic core column is withdrawn from a supporting state, the rest elastic core column continuously keeps the supporting state, and the whole supporting device is in an elastic state. Because the steel structure body has certain rigidity, the steel structure continues to produce and warp, and the pressure that the elasticity stem received continues to reduce.
(5) When the vertical telescopic devices at the lower parts of all the elastic core columns are in a contraction state, the steel structure becomes a stable structure under the action of the rigidity of the body, pressure is not generated on the supporting device any more, and the supporting device can be dismounted.
Finally, it should be noted that: the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the technical solution of the present invention, and the protection scope of the present invention is not limited thereto, although the present invention is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: those skilled in the art can still modify or easily conceive of changes in the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
