Supporting construction method and structure for existing building structure column transformation
The invention discloses a supporting construction method and structure for existing building structure column transformation. An upper holding column beam (8) an a lower holding column beam (9) are added on an original structure column (4), supporting steel pipes (13) are adopted for serving as temporary supports of the upper holding column beam (8) an the lower holding column beam (9), the top ends of the supporting steel pipes (13) are fixed through exertion of prestress force to the supporting steel pipes by a jack (15) and a jack limiting device (16), multiple supporting steel pipes are connected through angular steel to form a whole body, a part of original structure column required to be dismounted is dismounted, according to design needs, construction is carried out again, and transformation is finished. The structure self bearing force and safety property needs in the construction process can be met, operation in the dismounting and transforming structure construction process can be provided, continuous use of existing building engineering is facilitated, and the aim of comprehensive use of an existing building can be achieved.
本发明公开了一种既有建筑结构柱改造的托撑施工方法及结构，本发明是在原结构柱（4）上增设上抱柱梁（8）和下抱柱梁（9）；采用支撑钢管（13）作为上抱柱梁（8）与下抱柱梁（9）的临时支撑。支撑钢管（13）顶端通过千斤顶（15）和千斤顶限位装置（16）对支撑钢管施加预应力并固定；再将多根支撑钢管通过角钢（16）连接形成整体；拆除需拆除部分原结构柱，按设计要求重新施工；改造完成。本发明既满足了施工操作过程的结构自身承载力和安全性要求；又能提供拆改结构施工过程的可操作性，有利于既有建筑工程的可持续使用，达到既有建筑的综合利用的目的。
