Example Embodiment
[0017] Example 1 (see attached Figure 1-4 )
[0018] The present invention is a lattice type steel-reinforced concrete composite beam, which is composed of lattice type steel skeleton 3, prefabricated lattice type steel skeleton concrete lower beam 1 and cast-in-place lattice type steel skeleton concrete upper beam 2. The structural steel skeleton is composed of combined section steel and steel bars; the combined section steel is composed of upper square steel pipe 4-1, bottom angle steel 4-2 and U-shaped steel 4-3 on both sides of the middle, and the upper reinforcement 5-3 is distributed in the combined section steel. Above the upper part, the lower rebar 5-1 is correspondingly arranged outside the lower part of the U-shaped steel 4-3 on both sides of the middle part, and the vertical inner rebar hoop 5-4 is arranged at intervals, bypassing the upper rebar 5-3 and the bottom angle steel 4-2 of the combined steel , Hoop to form a cage; the transverse outer steel hoop bypasses ...
