钢管混凝土柱升板结构新工艺的研究

A RESEARCH ON NEW TECHNOLOGY OF LIFT-SLAB STRUC-TURE PROJECT USING STEEL TUBE CONCRETE COLUMN

升板结构中钢管混凝土柱代替预制混凝土柱可提高柱的承载力，施工方便，并可降低工程造价，缩短工期。足尺寸试验研究结果表明，采用钢管混凝土柱外贴焊钢板配合特制的钢卡环等措施，可解决施工中板的临时搁置、就位、升板机固定等技术问题。

The adoption of steel tube concrete coulumn to substitute precast reinforced concrete column in a lift -slab structure project has been proved of the following advantages: 1, increase of column's bearing capacity, 2,easy construction,3, decrease of construction cost and 4, shortening of construction period. The results of a full scale specimen tast have clearly demonstrated that steel tube concrete coloumn attached externally with steel plate and clamps would solve those technical problems such as : the temporary placement and setting of steel plate and fixing of lift-slab machine.
