A tool type assembly platform comprises a platform framework and a platform board which are connected with a building, the platform framework is formed by connecting two layers of steel frameworks, each layer of the steel framework is formed by crossly connecting a beam and a longitudinal beam, the upper and lower layers of the steel frameworks are connected by a vertical column and bolts, the two sides of the platform framework are respectively connected with a main longitudinal beam by a row of long angle steel connecting parts and the bolts, the main longitudinal beam has upper and lower channel steels which are parallel, the two channel steels are connected by a row of channel steel connecting parts, one end of the main longitudinal beam extends into a floor board of the building; a steel pipe connecting part is welded at the side surface of the platform framework, the steel pipe connecting part is provided with a vertical round steel pipe, a belt bolt is penetrated on the side wall of the round steel pipe, and a protection railing is inserted into the round steel pipe and fixedly connected with the round steel pipe by at least two fastening bolts which are vertically arranged. The tool type assembly platform can rapidly install a raised operation platform with higher firmness and solve the problem that the operation platform and a discharging platform can not be interchangeable.
