This application relates to the field of building support, and in particular to an early-stripping support system for steel truss floor slabs. The system includes several parallel and vertically arranged support members; multiple horizontal connecting rods vertically fixed between adjacent support members; and several quick-release plates. Each support member has a quick-release joint at its end near the bottom formwork. Adjacent quick-release plates are fixed at both ends of the quick-release joints and abut against the bottom formwork. The quick-release plates and the lower chord reinforcement on the bottom formwork are located in the same vertical plane. This application achieves the technical effect of stably supporting steel truss floor slabs without the need for reusable scaffolding or thickened bottom formwork, and the structure is easy to install and disassemble.
