This invention provides a precast concrete trough slab combined with a steel support beam reinforcement component and method. The reinforcement component includes a combined steel support beam, which consists of a T-shaped steel beam and two steel plates. The web of the T-shaped steel beam passes through the joint between the two precast concrete trough slabs from bottom to top. Steel plates are fixed to both sides of the web of the T-shaped steel beam. Two connecting supports are provided, which are respectively connected to both ends of the combined steel support beam. The bottom of the connecting supports is installed at the top of the load-bearing wall. This reinforcement component significantly improves the load-bearing capacity of the precast concrete trough slab without increasing the weight of the floor slab, without changing the stress mode of the precast concrete trough slab or the stress mode of the transverse walls in the structure. It increases the support length of the precast concrete trough slab, meeting current specifications, and adds tie steel bands to improve overall integrity, avoiding the risk of floor slab detachment and collapse during earthquakes.
