[0007] The steel truss floor deck includes a bottom formwork steel plate and web reinforcements, wherein the upper end of the web reinforcement is welded with an upper chord reinforcement, and the lower end of the web reinforcement is welded with a lower chord reinforcement; and further includes:

[0008] A structural steel beam, wherein an angle bracket is arranged on the structural steel beam, the angle brackets are arranged symmetrically, an I-beam is arranged on the symmetrically arranged angle brackets, and a bottom formwork steel plate is arranged between the angle brackets and the structural steel beam;

[0009] The "J"-shaped steel bar hooks are evenly distributed along the length direction of the I-beam and placed on the upper end surface of the I-beam, and the upper chord steel bars are arranged on the hooking ends of the "J"-shaped steel bar hooks.

[0010] As a further solution of the utility model: a bolt is connected between the angle bracket and the structural steel beam, and the bolt passes through the bottom opening of the angle bracket and is welded and fixed to the bottom mold steel plate and the structural steel beam.

[0011] As a further solution of the utility model: bolts are connected between the angle bracket and the I-beam.

[0012] As a further solution of the utility model: the angle bracket is connected to the flange of the I-beam by bolts.

[0013] Due to the adoption of the above technical solution, the utility model has the following advantages:

[0014] 1. By evenly distributing the "J"-shaped steel hooks along the length of the I-beam and placing them on the upper end surface of the I-beam, the upper chord steel bars are set on the hook ends of the "J"-shaped steel hooks, thereby optimizing the force-bearing mode of the steel truss floor deck installation. The structural steel beam is used as a support and a temporary gantry hanger is added above it. The lower support is changed to an upper suspension, and the force transmission path is simple and reasonable.

[0015] 2. Cancel the temporary support system under the large-span steel truss floor slab to reduce material input and speed up construction progress. BRIEF DESCRIPTION OF THE DRAWINGS
