Girdle truss, manufacturing method of girdle truss and super high-rise building giant frame
The invention relates a girdle truss, a manufacturing method of the girdle truss and a super high-rise building giant frame. The girdle truss comprises an upper chord, a lower chord and a corrugated steel web, wherein the upper chord adopts a steel tube concrete-filled upper chord, the lower chord adopts a prestressed steel tube concrete-filled core rod, and the upper end and the lower end of thecorrugated steel web are in rigid connection with the upper chord and the lower chord respectively to form the girdle truss; and a plurality of honeycomb through holes are formed in the corrugated steel web at equal intervals. According to the girdle truss, the manufacturing method of the girdle truss and the super high-rise building giant frame, the steel tube concrete-filled upper chord is usedas an upper chord member of the girdle truss, so that the compression bearing capacity and rigidity of the upper chord of the girdle truss are enhanced; the prestressed steel tube concrete-filled corerod is used as a lower chord member of the girdle truss, so that the tensile bearing capacity and rigidity of the lower chord of the girdle truss are improved; the corrugated steel web with the honeycomb through holes are adopted to replace a girdle truss diagonal web member, so that the shear bearing capacity is improved, daylighting performance and permeability of the girdle truss are improved,and girdle truss construction is simplified. The girdle truss is excellent in stress performance and has a good application prospect.
本发明涉及一种环带桁架、环带桁架制造方法及超高层建筑巨型框架，环带桁架包括上弦杆、下弦杆及波形钢腹板，上弦杆采用钢管混凝土上弦杆，下弦杆采用预应力钢管混凝土芯棒，波形钢腹板上、下端分别与上弦杆、下弦杆刚性连接，形成一榀环带桁架，波形钢腹板上等间隔开设有若干蜂窝通孔。本发明采用钢管混凝土上弦杆作为环带桁架的上弦构件，可增强环带桁架上弦的抗压承载力和刚度；采用预应力钢管混凝土芯棒作为环带桁架的下弦构件，可提高环带桁架下弦的抗拉承载力和刚度；采用具有蜂窝通孔的波形钢腹板替代环带桁架斜腹杆，可提高抗剪承载力，增加环带桁架采光性和通透性，简化环带桁架施工。环带桁架受力性能优良，具有良好的运用前景。
