Description

Technical Field

[0001] The utility model belongs to the field of building plate installation fuselage, and in particular relates to a combined type composite floor plate with a bottom sealing mold structure. Background Art

[0002] In the construction industry, composite floor slabs are often supported using a combination of steel pipe and timber formwork. Because composite floor slabs have very smooth surfaces, steel pipe and timber formwork structures experience high material turnover, are prone to deformation, and are prone to formwork expansion and grout leakage near the lower support slab. After pouring, concrete leaks and bulges significantly at the bottom, creating a poor appearance. Later repairs, including chiseling and repairs, waste significant labor and materials, and the quality of the repaired slabs is uncertain. Therefore, a modular composite floor slab with bottom-sealed formwork is needed to overcome these issues. Summary of the Invention
