Steel column internal flow stopping device for concrete-filled steel tube jacking and using method thereof
The invention discloses a steel column internal flow stopping device for concrete-filled steel tube jacking and a using method thereof. The steel column internal flow stopping device comprises a flowstopping plate attached to the inner wall of a steel column, wherein lubricating sealing layers are arranged on the flow stopping plate and the inner wall of the steel column; a flow stopping plate through hole is formed in the flow stopping plate; two positioning nuts are fixed to the side, close to the lubricating sealing layers, of the flow stopping plate; the positioning nuts are clamped in long circular holes formed in the steel column; bolt rods with the length larger than the wall thickness of the steel column are screwed in the positioning nuts; the bolt rods extend to the outer side of the steel column through the long circular holes; adjusting nuts are further installed on the bolt rods positioned on the outer side of the steel column; the outer diameter of the adjusting nuts islarger than the width of the long circular holes; and the flow stopping plate is fixed to the inner wall of the steel column through the cooperation of the adjusting nuts and the bolt rods so as to limit free sliding of the flow stopping plate. The device is simple, convenient to operate and low in cost, after the bolt rods and the adjusting nuts are jacked, the adjusting nuts are tightened, and when the long circular holes are subjected to repair welding, the adjusting nuts can be detached and can be repeatedly used for other parts of engineering.
本发明公开了一种用于钢管混凝土顶升的钢柱内止流装置及其使用方法，包括贴设在钢柱内壁上的止流板，止流板和钢柱内壁设置有润滑密封层，止流板上开设止流板通孔，止流板靠近润滑密封层的一侧上固定有两个定位螺母，定位螺母卡设在钢柱上开设的长圆孔内，定位螺母内拧装有长度大于钢柱壁厚的螺栓杆，螺栓杆通过长圆孔延伸至钢柱外侧，位于钢柱外侧的螺栓杆上还安装有调节螺母，调节螺母的外径大于长圆孔的宽度，通过调节螺母配合螺栓杆将止流板固定在钢柱内壁上以限制止流板的自由滑动。本发明装置简单、操作便捷，成本较低，螺栓杆及调节螺母在顶升完毕后，调节螺母把紧，在补焊长圆孔时，即可卸掉，可重复利用在工程其他部位。
