Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a waterproof structure of a horizontal construction joint of a rigid column on an outer wall of a basement and a construction method thereof. Background Art

[0002] At present, the steel-concrete structure is a construction method that combines conventional civil engineering and steel structure. In actual construction, the waterproofing of the rigid columns of the basement exterior wall is prone to problems, because the existing water-stop steel plates will take two forms when encountering rigid structural columns: bypassing and welding with the structural columns. However, bypassing and welding with the structural columns both make the water-stop steel plates have too many joints, making it difficult to control the construction quality, inconvenient to construct, and poor in waterproofing effect. The basement exterior wall is prone to leakage at this horizontal construction joint position, so the present invention was born. Summary of the invention
