[0006] Preferably, the bottom of the composite carbon fiber net is further provided with a bottom die.

[0007] Compared with the prior art, the utility model has the beneficial effects that:

[0008] 1. By welding the steel mesh and the skimmer, a layer of steel mesh is welded below the steel bar truss with the skimmer, and high-performance self-compacting concrete is poured, so that the strength is improved, and the weaving mold and support are truly avoided, and the existing steel bar truss floor support plate construction needs to be supported every 1.5 meters, and by using the above structure and increasing the steel mesh, 6-15 meters of support-free can be realized.

[0009] 2. By the screw thread high strength composite fiber combined reinforcing bar with a diameter of 10-15 cm, and by setting a screw thread structure outside the screw thread high strength composite fiber combined reinforcing bar, the gripping force with the high-performance self-compacting concrete is strengthened, the truss floor support plate body bottom surface after curing and solidification is not attached to the mold, the truss floor support plate body bottom surface is flat and defect-free, the strength is high, and the truss floor support plate body bottom surface is not easy to break.

[0010] 3. The existing steel bar truss is welded with iron sheet, the strength is not high and the welding is easy to be removed, and during pouring of the floor support plate, a support column needs to be erected every 1.5 meters due to the low strength, and the construction is complex and difficult, and the technology effectively avoids the need for support every 1.5 meters during construction of the existing steel bar truss floor support plate, and by using the above structure and increasing the cold-drawn steel mesh, 6-15 meters of support-free can be realized.

[0011] 4. The top chord of the steel bar truss is a steel pipe, the steel pipe is attached with a composite carbon fiber net cylinder, the compressive strength of the top chord is 10-40 times that of the steel top chord of the ordinary steel bar truss, and 6-15 meters of support-free can be realized without disassembling the bottom die.

[0012] 5. Previously used wire mesh sheets all had the same fixed aperture, but the size of the steel truss varied, causing the tops of the flared corners on both sides of the steel truss to be unable to align and weld with the vertical bars of the wire mesh. This patented design uses specially made wire mesh sheets based on the interval between the flared corners on both sides of the steel truss, ensuring that the tops of the flared corners are aligned and welded with the vertical bars of the wire mesh, resulting in higher compressive and tensile strength.
