The invention relates to a method for controlling wall body crevices. The method for controlling the wall body crevices comprises the following steps that firstly, information is collected; secondly,a model family library is constructed, and by utilizing a Revit software, a building information modeling (BIM) wall body standard parameterized model family library of a wall body is established; thirdly, a BIM wall body three-dimensional model is established, wherein the BIM wall body three-dimensional model comprises manufacturing constructional steel bars, casting molding plates, split bolts,concrete structure layers and structural steel bar nets; fourthly, configuration and optimization are conducted, wherein the configuration condition of the structural steel bar nets is inspected layerby layer through BIM model simulated view; fifthly, simulated analysis design is conducted, wherein a BIM building information model established by the Revit software is imported into Navisworks software, and real-time roaming is conducted; sixthly, a material list is generated, wherein the quantity of materials needed by each layer of the wall body structure is counted by applying the BIM software detailed list function, the material list is generated, and the site construction scheme is determined; and seventhly, technology disclosure is conducted, wherein through an animated short film manufactured with a 3Dmax software or Navisworks software, visualized construction technology disclosure is conducted on site construction staff, and all-round instruction of construction is conducted. The method for controlling the wall body crevices has the effect that the possibility that the crevices are generated by the wall body is reduced.
