The installation and setting out of the steel structure floor support plate need to check the size first.We know that the installation process of steel structure floor bearing plate is not simple laying, but a more rigorous process, such as detailed design first.

　　1.Firstly, check the installation dimension of steel structure and review the layout of floor bearing plate.

　　2. when installing the floor bearing plate, snap a reference line at both ends of the floor beam, which is 50mm from the flange edge of the steel beam.

　　3. when the floor bearing plate is constructed by butt joint, the datum line at the end of the floor bearing plate is located at the center of the wing plate of the steel beam.

　　4. for the setting out of baffle construction, the line snapping construction shall be carried out after the cantilever size is deducted from the length of baffle plate.

        5. The baffle plate at the curve overhang can be set out partially, but the overhang curve shall be parallel to the steel structure curve as far as possible.
