Along with the further promotion of commercial concrete, strengthening the control of crack is the key problem for the construction units in the progress of commercial concrete beam and slab structure construction. Commercial concrete beam slab structure is related to the quality of the whole project, and has important influence to the project construction. This paper analyzes the case of the early crack control in the commercial concrete beam and slab structure construction, and discusses the corresponding reasons of the crack, finally puts forward the measures for the construction process control. It has important significance for the early crack control for the commercial concrete beam and slab structure construction.% 随着商品砼的不断推广，在商品砼梁板结构的施工过程中，加强对裂纹控制是施工单位关注的重点问题。商品砼梁板结构关系到整体工程的质量，对工程的施工有着重要的影响。本文对商品砼施工早期产生裂纹的情况进行分析，并且对产生裂缝的相应原因进行了探讨，最后提出了对于施工过程控制的措施，对于商品砼梁板结构施工早期裂纹控制有着重要的意义。
