The invention relates to the technical field of granite ice crack laying, in particular to a granite ice crack laying tool and a
modular construction method.The granite ice crack laying tool comprises a plurality of nesting boxes, the shapes of the nesting boxes are different, the number of edges of each nesting box is larger than four, and the number of the edges of each nesting box is larger than four. Every two adjacent nested boxes are connected through a connecting mechanism, and the width of an abutted seam between every two adjacent nested boxes ranges from 5 cm to 15 cm. The method has the advantages that the broken splicing units are designed in advance through drawing
software, subjective influence is reduced through construction with modules as units, the seam width is controlled through the nested
box set, falling plate positioning is facilitated, the
quality control difficulty is reduced, the complex on-site splicing process is converted into assembling of the fixed units, and the production efficiency is improved. The design of the nesting box group further reduces the process of repeated adjustment after plate falling, improves the work efficiency and reduces the cost.
