Construction method for supporting beam and pulling column

BAI JINYUAN / HU YING / CHENG YA / XU PENG / SHAO HAO

The invention provides a construction method for supporting a beam and pulling a column, which comprises the following steps of: building an unloading assembly supported at the bottom of a frame beam, arranging an underpinning area on a to-be-pulled supporting column, supporting a load guide assembly in the underpinning area, supporting the load guide assembly through a load assembly, and applying a load applied to the to-be-pulled supporting column by the frame beam to the load assembly, and at the moment, the unloading assembly can be disassembled, so that the frame beam is reinforced, and after the frame beam is reinforced, the to-be-pulled-out supporting column is chiseled away. When the construction method is used for carrying out beam supporting and column pulling, due to the fact that the unloading assembly supported at the bottom of the frame beam is dismantled before the frame beam is reinforced, the unloading assembly does not occupy the space of the lower portion of the frame beam, a larger construction space is provided for subsequent frame beam reinforcement, the reinforced beam can be reinforced and formed at a time, segmented reinforcement is not needed, and the construction efficiency is improved. And the construction efficiency of frame beam reinforcement is improved.

本发明提供一种托梁拔柱的施工方法，包括以下步骤：搭建支撑于框梁底部的卸荷组件，在拟拔除支撑柱上设置托换区，将导荷组件支撑于该托换区内，通过载荷组件支撑导荷组件，使框梁施加于拟拔除支撑柱上的载荷施加于载荷组件上，此时可将卸荷组件拆除，从而实现对框梁的加固，待框梁加固后将拟拔除支撑柱进行凿除即可。利用这种施工方法进行托梁拔柱时，由于在加固框梁之前拆除支撑于框梁底部的卸荷组件，卸荷组件并不会占用框梁下部的空间，为后续框梁加固提供了更大的施工空间，加固梁可以一次加固成型，无需分段加固，提升了框梁加固的施工效率。
