Steel bar truss floor support plate convenient to construct

The utility model relates to the technical field of steel bar truss floor bearing plates, and discloses a steel bar truss floor bearing plate convenient to construct, which comprises a placing plate, an assembling mechanism and a convenient mechanism are arranged on the outer surface of the placing plate, and due to the existence of a first inclined block and a second inclined block, a long block and a transverse block form a triangular shape through a first long rod and a second long rod. Triangles have high stability, supporting rods are arranged to support long blocks, the effect of stabilizing the long blocks is achieved, when different steel bar truss floor support plates are assembled, telescopic rods are shortened and enter second circular grooves, the long grooves are aligned with the long blocks to assemble different placing plates at the moment, the telescopic rods enter first circular grooves to be clamped with each other at the moment, and then the long blocks are assembled. Namely, the long groov
