Fusiform anti-buckling support
The invention relates to a fusiform anti-buckling support and belongs to the technical field of structural engineering. The fusiform anti-buckling support is composed of a cross-shaped inner core component and a peripheral fusiform steel pipe concrete constraint component. The cross sections of the portions, at the supporting ends, of a fusiform constraint steel pipe is minimum, the cross sections of the portions, far away from the ends, of the fusiform constraint steel pipe gradually increase evenly, and the cross section of the supporting middle of the fusiform constraint steel pipe is maximum. Round steel pipes or square steel pipes can be adopted as the fusiform constraint steel pipe, two frustum-shaped steel pipes are welded in an opposite buckled mode to form the fusiform constraint steel pipe, and concrete is poured into the fusiform constraint steel pipe. According to the fusiform anti-buckling support, when the peripheral component is extruded by the inner core, the bending moment of the middle cross section of the component is large, the bending moment of the end cross sections of the component is small, and at the same time, the middle bending rigidity of the fusiform constraint component is large, which is consistent with the internal force distribution rule of the fusiform constraint component. Compared with an equal-cross-section peripheral constraint component, although the middle cross section of the fusiform constraint component may be slightly increased, the size of the cross sections close to the ends is remarkably reduced, the dead weight of the whole component can be effectively reduced, and transportation is convenient; the component is more attractive in appearance and favorable for architectural modeling.
