Roof panel column head and newly-built structural column closure construction system and construction method thereof
The invention relates to a roof panel column head and newly-built structural column closure construction system and a construction method thereof, and belongs to the technical field of house maintenance and reconstruction. According to the system, the roof panel column head is reserved at the roof panel beam crossing position at the bottom of a roof panel, a joint bar is reserved at the bottom of the roof panel column head, and the joint bar is connected with a structural column steel bar; formworks are erected on the periphery of the newly-built structural column, the tops of the formworks are in a horn mouth form, and the top elevation of the formworks is higher than the bottom elevation of the roof panel column head; and non-shrinkage self-compacting concrete is adopted for pouring. the joint bars are connected with the structural column steel bars, so that the shear resistance of the construction joint part can be enhanced; by arranging the formworks with the horn-shaped top, the operable surface of construction machinery is enlarged, and vibrating rods can be put down conveniently; and in the pouring process, the height of a pouring completed face is observed through observation and pouring holes reserved in the roof panel, the pouring compactness of the construction joint position is ensured, and the concrete construction quality and the structural integrity are effectively improved.
本发明的屋面板柱头与新建结构柱合拢施工系统及其施工方法属于房屋维修改造技术领域，该系统通过在屋面板底部的屋面板梁交叉位置处预留屋面板柱头，并且在屋面板柱头的底部预留插筋，插筋与结构柱钢筋连接。在新建结构柱的四周支设模板，模板的顶部为喇叭口形式，并且模板的顶部标高高于屋面板柱头的底部标高。采用无收缩自密实混凝土浇筑。通过插筋与结构柱钢筋连接，可以增强施工缝部位的抗剪性能。通过设置顶部为喇叭口形式的模板，加大了施工机械可操作面，方便振捣棒下放。浇筑过程中通过屋面板预留的观察与灌注孔观测浇筑完成面高度，确保施工缝位置浇筑的密实性，有效提升了混凝土的施工质量及结构的整体性。
