Chimney rollover construction method with structural refractory bricks serving as inner mold
The invention discloses a chimney rollover construction method with structural refractory bricks serving as an inner mold, which comprises the following steps: firstly, erecting a scaffold in a chimney cylinder body, enabling a steel pipe of the scaffold not to extend into the cylinder wall of the chimney, arranging a lifting channel in the middle of the scaffold, and mounting a construction platform and a lifting device at the upper end of the scaffold; two groups of outward turning molds are arranged up and down along the outer circumference of the chimney cylinder body; steel bars are installed on the cylinder wall in the chimney cylinder body direction; building a refractory brick lining and a heat insulation layer along the inner circumference of the chimney, and then installing a supporting piece; concrete is poured between the heat insulation layer and the outwards-turning formworks, and after the strength of the concrete reaches the set strength, the lower set of outwards-turning formworks are dismantled and installed above the upper set of outwards-turning formworks; a reinforcing rod used for keeping the scaffold stable is installed, and the two ends of the reinforcing rod abut against and are aligned with the inner walls of the refractory brick linings of the disassembled outward turning formworks correspondingly; and the scaffold continues to be erected upwards, and then the construction platform and the lifting device are moved upwards. The chimney has the effect of prolonging the service life of the chimney.
本申请公开了一种结构用耐火砖兼做内模的烟囱翻模施工方法，其先在烟囱筒身内搭设脚手架，脚手架的钢管不伸入烟囱的筒壁中，脚手架的中间设提升通道，在脚手架的上端安装施工平台和提升装置；沿烟囱筒身外圆周安装上下设置的两组外翻模；沿烟囱筒身方向在筒壁处安装钢筋；沿烟囱内圆周砌筑耐火砖内衬和隔热层，之后安装支撑件；在隔热层和外翻模之间浇注混凝土，待混凝土的强度达到设定强度后，拆除下方一组的外翻模并安装到上方一组的外翻模的上方；安装用于保持脚手架稳定的加固杆，加固杆的两端分别顶紧对齐拆除的外翻模的耐火砖内衬的内壁；往上继续搭设脚手架，然后往上迁移施工平台和提升装置。本申请具有提高烟囱的使用寿命的效果。
