Open-web sandwich plate one-time pouring construction method
The invention provides an open-web sandwich plate one-time pouring construction method which comprises the steps that formwork erecting and steel bar binding are conducted on a whole open-web sandwich plate, and a plurality of air holes are formed in the upper end of a lower rib beam formwork at intervals; specially-made concrete reaching the preset fluidity is poured into the lower ribbed beam supporting formwork through the shear key supporting formwork till the lower ribbed beam supporting formwork and the shear key supporting formwork are filled; the upper ribbed beam supporting formwork and the plate face supporting formwork are filled with common concrete with the same mark number, the lower ribbed beam supporting formwork and the shear key supporting formwork can be densely filled with the specially-made concrete through the fluidity of the specially-made concrete and the air holes formed in the upper end of the lower ribbed beam supporting formwork, pouring of the upper ribbed beam supporting formwork and the lower ribbed beam supporting formwork can be continuously completed, the construction period is effectively shortened, and the construction efficiency is improved. Construction joints are avoided, and the construction method has the advantages of being good in construction quality, high in efficiency and short in period.
本发明提供了一种空腹夹层板一次性浇筑施工方法，所述方法包括：对整个空腹夹层板进行支模及钢筋绑扎，并在下肋梁支模的上端间隔设置多个透气孔；将达到预设流动性的特制混凝土通过剪力键支模往下肋梁支模内浇筑，直至所述下肋梁支模及所述剪力键支模填满；将同标号的普通混泥土填满上肋梁支模和板面支模，通过特制混泥土的流动性，并在下肋梁支模的上端设置透气孔，使得特制混泥土能够密实填充满下肋梁支模和剪力键支模，即可不间断完成上、下肋梁支模浇筑，有效节约了工期，避免了施工缝的产生，具有施工质量优、效率高、周期短的优点。
