Inclination rectifying structure of newly-added inverted-L-shaped beam of masonry structure foundation and limiting iteration jacking method of inclination rectifying structure
The invention provides an inclination rectification structure of a newly-added inverted-L-shaped beam of a masonry structure foundation and a limiting iteration jacking method of the inclination rectification structure, and belongs to the technical field of building inclination rectification. The inverted-L-shaped beams are additionally arranged on the two sides of the bottom of the whole settlement area masonry structure foundation correspondingly, and the integrity of the masonry structure is improved during jacking; a reinforced concrete bearing platform is arranged on the foundation, steel plates are arranged on the bearing platform and the bottom of the inverted-L-shaped beam respectively, and a jack is placed between the inverted-L-shaped beam and the reinforced concrete bearing platform; jack jacking adopts a limiting iteration jacking loading method, after indoor cracks are completely closed, the cracks between the foundation and the foundation are filled with dry hard concrete, and after maintenance reaches the design strength, the jacks are dismantled, and the positions of the jacks are filled with plain concrete; the inclination rectifying capacity of the masonry structure foundation is reliable, the construction method is simple and clear, the cost is low, the period is short, and the safe, simple and green inclination rectifying structure and the construction method thereof are provided for the masonry structure with poor integrity.
本发明提供了一种砌体结构基础新增倒L型梁的纠倾结构及其限位迭代顶升方法，属于建筑物纠倾技术领域。本发明在整个沉降区砌体结构基础底部两侧分别新增倒L型梁，顶升时提高砌体结构的整体性；并在地基上设置钢筋混凝土承台，承台上及倒L型梁底部分别设置钢板，在倒L型梁和钢筋混凝土承台之间放置千斤顶；千斤顶顶升采用限位迭代顶升加载法，室内裂缝完全闭合后，对基础和地基之间的裂缝采用干硬性混凝土进行填塞，养护达设计强度后，拆除千斤顶并在千斤顶位置处填充素混凝土；本发明对于砌体结构基础的纠倾能力可靠，施工方法简单明确，成本低，周期短，为整体性较差的砌体结构提供了一种安全、简单、绿色的纠倾结构及其施工方法。
