The invention discloses a reinforcement tool for a beam template. The reinforcement tool for the beam template comprises two main arms which are parallel to each other. One ends, at the same side, of the two main arms are connected through a support component. The middle portions of the two main arms are connected through a clamping component. The support component is a height-adjustable support component. The height-adjustable support component is the support component for an adjustable screw rod, or the height-adjustable support component is the support component for an adjustable piston rod. The clamping component is a screw rod clamping component, a twisted strip clamping component or a steel pipe clamping component. The reinforcement tool for the beam template can be suitable for support formworks of different beam width without changing the support component, the construction efficiency is improved greatly, the energy is saved, the national green energy-saving and environmental-protection are conformed, and standard construction can be achieved; the reinforcement tools for the beam template of different support components can be produced according to the demand of a customer, and the reinforcement template for the beam template of different clamping components can be produced according to actual conditions.
