The beam column connecting joint suitable for the H-shaped steel beam of the concrete column comprises a concrete column, wherein reinforcing bolts are arranged in the concrete column in a pre-embedded mode, extend out of the surface of the concrete column, a guard plate is sleeved on the outer ring of the concrete column, positioning holes matched with the reinforcing bolts are formed in the guard plate, and the H-shaped steel beam is arranged on the outer ring of the guard plate through the penetrating reinforcing bolts.

Working process or working principle:

firstly, in the construction process, reinforcing bolts are pre-buried into a frame to be poured of a concrete upright in advance, the corresponding positions of the reinforcing bolts are fixed, after the concrete upright is poured, a guard plate is installed, each seam of the guard plate is welded, after the reinforcing bolts pass through positioning holes in the guard plate, the positioning holes are welded, the guard plate and the reinforcing bolts are fixed together, the stability is improved, and finally, an H-shaped steel beam is fixed to the reinforcing bolts on the guard plate, so that the anti-seismic requirements of strong and weak beams and strong and weak members are met, the stress is reasonable, and the installation is convenient.

Further, the section of the concrete upright post is one of square, L-shaped, T-shaped or cross-shaped.

Further, an end plate is arranged at one end of the H-shaped steel beam, and a connecting hole matched with the reinforcing bolt is formed in the end plate.

Further, the reinforcing bolts are welded and fixed with the outer ring of the positioning hole on the guard plate.

Further, the H-shaped steel beam is sleeved with a square pipe which is matched with the H-shaped steel beam.

Further, the reinforcing bolts are provided for studs.

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

1. the beam column node area has better integrity, so that the beam column node area meets the anti-seismic requirements of strong column, weak beam, strong node and weak components.

2. The utility model enhances the rigidity of the node, improves the integrity and the structural ductility, and ensures that the stress of the node is more reasonable.

3. The beam column is in field full-bolt connection, the construction is convenient, the construction period is shortened, and project cost is saved.
