[0016] The present utility model provides an assembled floor main support steel frame component, which has the following beneficial effects:

[0017] 1. The main support steel frame assembly for a prefabricated floor slab realizes the installation and fixation of the top plate by hoisting the floor slab and placing it on the top surface of the wing of the base, placing the top plate above the base, passing bolts through the sunken holes and locking them with the internal thread holes. The floor slab is limited within the abdomen of the I-shaped steel structure through the top plate to complete the installation. It has the characteristics of convenient installation and easy operation.
