The invention discloses a crack control structure of a micro-expansion concrete post-cast strip, which comprises end clamping plates which are fixedly clamped on two end faces of a concrete post-cast strip, wherein an upper clamping plate is fixed on an upper surface of the concrete post-cast strip. According to the micro-expansion concrete post-cast strip crack control structure, the end clamping plates and the upper clamping plate are respectively and fixedly clamped on two end faces and the upper surface of the concrete post-cast strip, so that the two end faces and the surface layer of the cast concrete post-cast strip are constrained, further, air shrinkage of micro-expansion concrete in the concrete post-cast strip in the airing and using stages can be effectively controlled, and cracks can be effectively prevented from being generated in the concrete post-cast strip. The crack control structure of the micro-expansion concrete post-cast strip is applied to the field of building construction.
