Construction method for reinforcing and transforming existing building structure
The invention provides a construction method for reinforcing and transforming an existing building structure, and belongs to the technical field of building construction. According to the technical scheme, the construction method comprises the steps of surveying and setting out, surface treatment, embedded steel bar construction, newly-added structural steel bar binding, inserting plate separation, formwork erecting and grouting material pouring. The structure has the beneficial effects that the structural form is transformed from a frame structure to a frame-anti-seismic wall structure, the anti-seismic construction measures of the frame part are still adopted according to three levels, and the construction measures of the newly added anti-seismic wall part are adopted according to two levels. In combination with the bearing capacity condition, an original frame column is reinforced by adopting a cross section enlarging method and a newly-added shear wall mode, a newly-added beam lower shear wall is connected with the cross section-added frame column, and concrete and grouting materials are respectively adopted for integral pouring, so that the whole reinforcement and transformation construction process is managed efficiently in real time, and the construction period and quality are ensured to meet the requirements.
本发明提供了一种对既有建筑结构加固改造的施工方法，属于建筑施工技术领域。其技术方案为：所述施工方法包括测量放线、表面处理、植筋施工、新增结构钢筋绑扎、插板分隔、模板支设和灌浆料浇筑。本发明的有益效果为：现将结构形式由框架结构改造为框架—抗震墙结构，框架部分抗震构造措施仍按三级采用，新加抗震墙部分构造措施按二级。结合承载力情况，原框架柱采取加大截面法及新加剪力墙方式进行加固，新加梁下剪力墙与增加截面框架柱相连，且分别采用混凝土和灌浆料进行一体浇筑，让整个加固改造施工过程做到实时高效的管理，确保工期和质量达到要求。
