钢制拱顶罐自采用SYJT标准图以来,在施工中,我们采用了以下几种做法。 1 倒装机具以前在钢制拱顶罐的施工中,由于罐体结构及尺寸各不相同,每次施工都要做一套伞架和倒装机具。为改变这种状况,我们首先在钢制拱顶罐结构标准化的基础上,摸索了施工机具的定型化,与之成龙配套。 1.1 倒装机具的结构及使用方法这种机具是在原采用的中心柱倒装的基础上经改进而成的。即将倒装机具制做成一个活动式的伞架结构,施工时,只需将预制好的一块外径略大于伞架外圆的环形板用螺栓固定在伞架上,连同伞架一起
Since the use of SYJT standard steel vault cans in the construction, we have adopted the following practices. 1 Flip-in equipment Previously, in the construction of steel vaults, due to the different structure and size of the tank body, an umbrella stand and flip-top equipment should be made for each construction. In order to change this situation, we first found out the standardization of the structure of the steel dome tank, and explored the finalization of the construction equipment. 1.1 The structure and use of flip equipment This machine is used in the original center column flip on the basis of improved. Flip-flops will soon be made into a movable umbrella structure, when the construction, just a good pre-made a slightly larger diameter than the outer ring umbrella plate bolted to the umbrella stand, together with the umbrella stand
