Connecting structure of concrete precast beam and steel beam and construction method of connecting structure

Abstract

The invention discloses a connecting structure of a concrete precast beam and a steel beam and a construction method of the connecting structure. The connecting structure comprises the concrete precast beam and the steel beam. Two grooves which are matched with the ends of the steel beam and are coaxial are reserved in the concrete precast beam, the two grooves are symmetrically formed in the two sides of the concrete precast beam, and a bolt hole for a split bolt to penetrate through is reserved between the two grooves. The ends of the two steel beams are arranged in the two grooves of the concrete precast beam, the split bolts penetrate through the bolt holes to fix the two steel beams, a fixing steel bar located on the upper sides of the steel beams is further arranged between the two steel beams, and the two ends of the fixing steel bar are welded and fixed to the two steel beams respectively. A gap at the joint of the concrete precast beam and the steel beam is filled with concrete. According to the connecting structure, the structural design is reasonable, the requirement for assembly precision is low, the steel beams are doubly fixed through the split bolts and the fixing steel bars, the gaps are filled with pouring concrete, and the connecting structure is good in reliability; the construction method is easy to operate and high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of construction engineering such as industrial workshops and warehouses, relates to a connection structure of a concrete prefabricated beam and a steel beam and a construction method thereof, and particularly relates to a prestressed concrete prefabricated beam with good reliability, accurate positioning and efficient and convenient construction The connection structure with the H-shaped steel beam and the construction method thereof. Background technique [0002] With the development of the construction industry, the prefabricated building construction technology has been used more and more widely due to its fast construction speed, high degree of mechanization and low construction safety risk, especially in prefabricated industrial plants and warehouses. [0003] The connection between concrete beams and steel beams is one of the key construction steps of prefabricated buildings. The reliability and positi...
