Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a seamless floor and a construction method thereof. Background Art

[0002] In the traditional factory building super-long and super-wide floor construction, the skipping method is mainly used. One warehouse is about 1200-1500 square meters. The warehouses are divided by armored seams or templates. After pouring, the seams are cut every 6m in each warehouse (the cutting area is preferably not more than 30 square meters) to ensure the release of stress and avoid cracking of the floor in the later stage, which will cause the following problems:

[0003] (1) Traditional concrete floors use armored seams or formwork as compartment materials, which may cause concrete shrinkage and cause the armored seams to open, causing forklifts to travel bumpy and unable to meet usage requirements.

[0004] (2) As a storage warehouse, the logistics warehouse will store a large number of heavy-loaded equipment for a long time. The use of conventional concrete flooring may cause uneven settlement of the ground after cutting, resulting in floor height differences, which will also affect subsequent use and forklifts cannot move safely.
