Beam slab node of renewable hybrid combined floor slab made of U-shaped steel-encased renewable hybrid beam and construction method thereof

The invention discloses a beam slab node of a renewable hybrid combined floor slab made of U-shaped steel-encased renewable hybrid beam and a construction method thereof. The node comprises a node domain, a supporting plate, a shear plate, a plurality of anti-shear studs and a plurality of negative bearing ribs. The supporting plate and the shear plate are arranged at a connection part of the renewable hybrid combined floor slab and the node domain, the renewable hybrid combined floor slab consists of a profiled steel plate and renewable hybrid concrete, the U-shaped steel-encased renewable hybrid beam consists of U-shaped encasing steel and renewable hybrid concrete, the profiled steel plate of the renewable hybrid combined floor slab is welded with the supporting plate through the anti-shear studs, the end plate of the profiled steel plate is welded with a sealing plate or welded with the U-shaped encasing steel, the supporting plate is welded with the U-shaped encasing steel, the shear plate is arranged under the supporting plate and is welded with the supporting plate and the U-shaped encasing steel, and the upper part of the node domain is provided with the negative bearing ribs. The node and the construction method have the advantages of good safety and reliability, convenient construction, environmental protection, energy conservation and emission reduction.
