Construction method for reinforcing and transforming super-large-span dragging beam and dismounting column
The invention relates to a construction method for reinforcement and transformation through super-large-span beam dragging and column dismantling. The construction method comprises the following steps that firstly, reserved columns and columns to be dismantled of a building to be transformed are determined; 2, determining a reinforcement construction monitoring scheme, arranging displacement and stress-strain monitoring identifiers, and collecting initial values; and 3, the size of the lower bearing platform of the reserved column is increased and reinforced, and a plurality of anchor rod static pressure piles are supplemented for foundation reinforcement to form a foundation bearing platform. According to the method, reinforcement treatment is conducted from bottom to top, the design is economical and reasonable, safety and reliability are achieved, real-time monitoring is achieved through displacement, stress and strain monitoring marks, damage to an original structure is reduced in the transformation process, and displacement, sedimentation, stress and the like of the original structure are accurately controlled in the column load unloading process; particularly, when the column needs to be completely disconnected, the stress of the supporting structure and the deformation of the beam are accurately tested and controlled.
本发明涉及一种超大跨度拖梁拆柱加固改造的施工方法，包括以下步骤：步骤1，确定待改造建筑物的保留柱、待拆柱；步骤2，确定加固施工监测方案，布置位移、应力应变监测标识，并采集初始值；步骤3，对保留柱的下承台尺寸进行增大加固，并增补若干数量的锚杆静压桩进行基础加固以形成基础承台。本发明中，通过自下而上进行加固处理，设计经济合理，安全可靠，通过利用位移、应力应变监测标识实现实时监测，在改造过程中减小对原结构的损伤，在柱荷载卸载过程中，将原有结构的位移、沉降、应力等进行精确控制，特别是需要将柱完全断开时，支撑结构的受力、梁的变形精确测试并加以控制。
