无井架液压滑动模板是建造钢筋混凝土烟囱的先进工具,在施工实践中,我们发现目前的烟囱设计还有许多和滑模施工不适应之处,在此提出来供设计人员参考。一、烟囱设计规格化。一套大烟囱的滑模钢结构,需要各种型钢10t左右,从设计到制造约要三个月时间,调动电、钳、铆、焊、车等工种参加,部件精确度要求高,工本较高。滑模钢结构的设计,需要烟囱壁最大外径和衬里最小内径这两个重要参数,来确定操作平台的大小和垂直运输的形式。现在各单位对等高烟囱的这两个重要参数的设计大多不一样,至于不等高烟囱,差别就更大了。一套滑模钢结构在完成一个烟囱施工
No derrick hydraulic sliding formwork is an advanced tool for constructing reinforced concrete chimney. In the construction practice, we find that there are many places where the chimney design does not meet the slipform construction, and this is proposed for designers’ reference. First, the design of the chimney is normalized. A slippery steel structure with a large chimney requires about 10 tons of various types of steel. It takes about three months from design to manufacture, and mobilizes electricity, clamps, rivets, welding, and other types of work. High precision is required for components. high. The design of the sliding mode steel structure requires the two important parameters of the maximum outer diameter of the chimney wall and the minimum inner diameter of the liner to determine the size of the operating platform and the form of vertical transport. Now the design of these two important parameters for the contour chimneys is not the same for all units. As for the different height stacks, the difference is even greater.
