Abstract
The invention provides a control method for preventing a factory grade level from cracking. The method comprises the step of: dividing the factory grade level into blocks for pouring, wherein the area of each block is less than or equal to 6*8 square meters; during pouring, benzene plates or foaming plates with the thickness of 8 to 10 millimeters are vertically arranged in a connected gap between every two adjacent blocks, on the edge of the wall and at the periphery of a column; and the height of each of the benzene plates or the foaming plates is 8 to 10 millimeters lower than the thickness of the grade level. The method has the advantages that: the benzene plates are arranged on the edge of the wall and at the periphery of the column; when the foundation of a house main structure is subjected to differential settlement, the adjacent grade levels and the peripheral wall surface are not influenced mutually due to the partition of the benzene plates, so the damage to the grade level is reduced greatly during the differential settlement,, and cracks due to a temperature difference between the indoor and the outdoor can be prevented; moreover, steel bars arranged at the periphery of the column enhance the integrity of the sides of the column; and after the pouring of the grade level is finished, the periphery of the grade level is subjected to lancing and caulked joint to reduce inclined cracks on the sides of the column effectively.
