The invention relates to the field of beam supporting and column pulling, in particular to a construction method for beam supporting and column pulling, which comprises the following steps of: 1, arranging a steel frame supporting foundation on the periphery of the bottom of a frame column; secondly, a steel frame supporting frame body with the proper height is arranged above the steel frame supporting foundation; thirdly, a supporting platform is arranged at the top of the steel frame supporting frame body; fourthly, after erection is completed, a plurality of jacks are placed on the supporting platform, and when the total pressure value evenly and synchronously applied by the jacks reaches the force borne by the tops of the frame columns, steel cushion blocks are placed on the supporting platform to reinforce the frame beams; and fifthly, after reinforcement is completed, the remaining frame columns are dismantled. The construction is convenient and the reliability is high when the joist and the column are pulled out, the steel frame supporting foundation, the steel frame supporting frame body and the supporting platform can be repeatedly utilized, and the construction cost can be saved; meanwhile, the steel cushion block is poured into the frame beam, and the section of the frame beam structure can be effectively enlarged.

本发明涉及托梁拔柱领域，尤其涉及一种用于托梁拔柱的施工方法，包括以下步骤：步骤一：在框架柱底部四周设置钢架支撑基础；步骤二：在钢架支撑基础上方设置合适高度的钢架支撑架体；步骤三：在钢架支撑架体顶部设置有支撑平台；步骤四：搭设完毕后，在支撑平台上放置多个千斤顶，千斤顶均匀同步施加的总压力值到达框架柱顶所承受力时，在支撑平台上放置钢垫块，对框架梁进行加固；步骤五：加固完毕后，拆除剩余框架柱。本发明进行托梁拔柱时施工方便、可靠性高，钢架支撑基础、钢架支撑架体和支撑平台可重复利用，能节约施工成本；同时，钢垫块浇筑到框架梁中，能有效增大框架梁结构的截面。
