Belt gallery joist pulling column transformation construction method
The invention relates to the technical field of old house transformation construction, in particular to a belt gallery joist column pulling transformation construction method. Comprising the following steps that firstly, a plurality of supports used for supporting steel beams are arranged under a belt corridor; 2, a steel beam is hoisted, and the two ends of the steel beam are supported on the supports correspondingly; 3, a temporary support is fixed to the middle of an old supporting column of the belt corridor; 4, a jack is arranged on the temporary support, and the steel beam is supported by the top of the jack; 5, the part, above the temporary support, of the supporting column is dismantled, and the load of the steel beam is transferred to the jack; 6, the support on the steel beam on the jack is removed, and the steel beam bears the belt gallery and deforms under stress; and 7, the jack and the temporary support are removed, and then the remaining part of the supporting column is removed. Through the scheme, the time for transferring the load to the steel beam and the time for stress deformation of the steel beam are staggered, and vibration of the steel beam after the load is instantly applied to the steel beam is avoided.
本发明涉及旧房改造施工技术领域，特别是涉及一种皮带廊托梁拔柱改造施工方法。包括一下步骤：步骤1，在皮带廊的正下方设置若干用于支撑钢梁的支座；步骤2，吊装钢梁，钢梁的两端分别支撑在支座上；步骤3，在皮带廊旧有的支撑柱的中部固定临时支座；步骤4，将千斤顶设置在临时支座上，所述千斤顶顶部支撑所述钢梁；步骤5，拆除支撑柱在临时支座以上部分，钢梁的载荷转移到千斤顶上；步骤6，卸掉千斤顶上的对钢梁的支撑，让钢梁承载皮带廊并且受力变形；步骤7，去掉千斤顶以及临时支座，然后拆除支撑柱的剩余部分。通过以上方案，载荷转移到钢梁上的时间和钢梁受力变形的时间错开，避免瞬间对钢梁施加载荷后钢梁的振动。
