Zusammenfassung:The utility model discloses anti-cracking construction equipment for a hogging moment area of a continuous composite beam bridge. The anti-cracking construction equipment comprises an anti-pulling non-shearing-resistant connecting piece, an anchoring piece, an inhaul cable and a center hole jack. The anti-pulling non-shearing-resistant connecting piece is used for being arranged at the top of a hogging moment area steel beam. When a hogging moment area concrete top plate is poured at the top of the hogging moment area steel beam; anchoring parts with inhaul cables are arranged at the two endsin the length direction of the hogging moment area concrete top plate. The center hole jack is arranged between the anchoring parts at the two ends of the hogging moment area concrete top plate in thelength direction; the other end of the inhaul cable on the anchoring part at one end of the two ends is connected with one end of the center hole jack; the other end of the inhaul cable on the anchoring part at the other end
