Abstract
The invention discloses an anti-fatigue pre-stress steel pipe column structure which comprises multiple sections of steel pipe columns, wherein all the sections of steel pipe columns are connected by flanges to constitute a tower pillar, and pre-stress cables are disposed inside the steel pipe columns from the tower pillar foot to the tower pillar top and respectively anchored on a lower end plate structure and an upper end plate which are located on the pillar foot and the pillar top. Under normal working conditions, as driven by wind loads and mechanical operation, pull force generated in the steel pipe column on one side of the tower pillar is smaller than pre-pull force applied inside the steel pipe column and the steel pipe pillar always keeps a stressed state, so that fatigue damages to the steel pipe column are avoided.
Description
Technical field
The invention belongs to highrise steel structure design field, be specifically related to a kind of can the prestress steel tubular column structure of antifatigue effect.
Background technology
Along with the development of highrise steel structure, for significant structure of fatigue problem under wind load and mechanical movement effect such as wind power generation stepped grade, steel strength fails to be fully used, and fatigue of steel structures problem becomes the restrictive condition that structural meterials makes full use of.For improving the utilization rate of material, prestressing force framework type tower (king-post adopts pre-stressed steel pipe, brace to adopt the flexible brace of prestressing force) can make steel tower column be in pressured state all the time, steel pipe column is interior without tensile stress in normal operation, and fatigue failure does not occur, steel strength can be not fully exerted.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of antifatigue prestress steel tubular column structure is provided, as the king-post that framework type is wind power generation stepped, replace traditional framework type king-post conventional combination angle steel king-post or shaped steel king-post, in king-post, apply axial prestress, make steel pipe column be in pressured state all the time under normal working load, do not produce tensile stress, prevent fatigue failure.
Antifatigue prestress steel tubular column structure provided by the invention, it comprises some joint steel pipe columns, each joint steel pipe column forms king-post by Flange joint, by king-post suspension column position to king-post capital position steel pipe column inside be equipped with prestressed cable and be anchored at respectively be positioned at suspension column and capital bottom plate structure and upper head plate on; Antifatigue prestress steel tubular column structure also comprises base plate, the steel pipe column of suspension column welds with base plate, base plate lower weld has bottom plate structure, the prestressed cable of the steel pipe column inside of suspension column passes bottom plate structure and uses anchor head anchoring, bottom plate structure ater-casting is cast in concrete foundation, and base plate crab-bolt is anchored in concrete foundation; Upper head plate is welded on capital, and the prestressed cable of the steel pipe column inside of capital passes upper head plate, is anchored on upper head plate after stretch-draw with anchor head.
Antifatigue prestress steel tubular column structure provided by the invention, its beneficial effect is, be positioned at the king-post position of framework type tower, by king-post suspension column position to king-post capital, be anchored on the end plate of suspension column and capital at steel pipe column internal placement prestressed cable, by carrying out stretch-draw at capital to prestressed cable, make prestressed cable and steel pipe column internal force balance, steel pipe column is in pressured state.Under wind load in normal working conditions and mechanical movement effect, the pulling force produced in the steel pipe column of king-post side is less than the pretension applied in this steel pipe column, and steel pipe column remains pressured state, avoids the fatigue failure of steel pipe column.
