The invention discloses a joint-cutting-free construction method for a large-area floor, which comprises the following steps of: dividing the large-area floor into bins, and dividing all bin sections into a construction section I and a construction section II; formwork erecting and concrete pouring are carried out according to the bin dividing sections, and adjacent bin dividing plates are poured in a staggered mode; after construction of the first-section terrace is completed, a sponge strip is pasted to an upper opening of the concrete side face of the first-section terrace, and then concrete pouring of the second-section terrace is conducted. According to the method, the concrete expansion cracks are greatly reduced by adopting the skip method construction, meanwhile, the sponge strips are matched, the sponge strips are used as occupancy at the kerfs, after concrete pouring is completed, the adjacent terraces are connected through the sponge strips, the effect of expansion joints can be achieved, the anti-cracking effect is remarkable, later-period kerfs are not needed, and the construction efficiency is improved. And compared with a traditional joint cutting process, the operation is greatly simplified, the construction efficiency is greatly improved, the overall cost is reduced, and the application prospect is good.
本发明公开了一种大面积地坪免切缝施工方法，步骤：大面积地坪分仓，将所有仓段分为施工一段和施工二段；根据分仓段进行支模浇筑混凝土，相邻分仓板块要错开浇筑；在完成施工一段地坪施工后在其混凝土侧面上口部粘贴海绵条，再进行施工二段地坪混凝土的浇筑。本发明的方法，采用跳仓法施工大大减少混凝土伸缩裂缝，同时与海绵条配合，以海绵条作为切缝处的占用物，在完成混凝土浇筑后，相邻的地坪之间即通过海绵条连接，能够起到伸缩缝的作用，其防裂效果显著，无需后期切缝，相比于传统切缝工艺，其大大简化了操作，大大提高了施工效率，降低了整体成本，应用前景好。
