Fabricated floor upper crack treatment method
The invention relates to the technical field of fabricated floors, and provides a fabricated floor upper crack treatment method. The method sequentially comprises the following steps that S1, a groove is excavated at the position of a crack at the upper portion of a fabricated floor; S2, a plurality of positioning structures are machined at the bottom of the groove; each positioning structure comprises two positioning holes; S3, a plurality of positioning steel bars bent into a groove shape are machined; the two ends of each positioning steel bar are inserted into the two positioning holes of each positioning structure; S4, a first shrinkage-compensating fine aggregate concrete layer is poured in the groove; a prefabricated glass fiber mesh is laid above the first shrinkage-compensating fine aggregate concrete layer; and a second shrinkage-compensating fine aggregate concrete layer is poured above the prefabricated glass fiber mesh until the whole groove is filled with the second shrinkage-compensating fine aggregate concrete layer. After the crack at the upper portion of the fabricated floor is treated, the crack cannot appear at the same position again, the treatment quality of the crack at the upper portion of the fabricated floor is guaranteed, and the appearance quality of the fabricated floor is improved.
本发明涉及装配式楼板技术领域，提供了一种装配式楼板上部裂缝处理方法，包括顺序进行的如下步骤：S1、在装配式楼板上部的裂缝位置处开挖凹槽；S2、在凹槽的底部加工若干组定位结构；每组定位结构包括两个定位孔；S3、加工若干个弯制成槽形的定位钢筋；将每个定位钢筋的两端分别插入每组定位结构的两个定位孔中；S4、在凹槽内浇筑第一补偿收缩细石混凝土层；在第一补偿收缩细石混凝土层的上方铺设预制玻璃纤维网片；在预制玻璃纤维网片的上方浇筑第二补偿收缩细石混凝土层，直至充满整个凹槽。当装配式楼板上部裂缝处理后，就不会在同个位置再次出现裂缝，保证了装配式楼板上部裂缝的处理质量，提高了装配式楼板的外观质量。
