Connection structure of prefabricated assembly type laminated plates and steel beam and connection method thereof

Abstract

The invention discloses a connection structure of prefabricated assembly type laminated plates and a steel beam. The connection structure comprises an H-shaped steel beam, the H-shaped upper surface of the H-shaped steel beam is fixedly provided with the reinforced truss concrete laminated plates in a bilateral symmetry mode, and the ends, fixed to the H-shaped steel beam, of the reinforced trussconcrete laminated plates are provided with through holes. Sleeves are anchored in the through holes. The sleeves extends out of the upper surfaces of the reinforced truss concrete laminated plates, the upper surfaces of the two reinforced truss concrete laminated plates are covered with a cover plate together, and the positions, corresponding to the through holes, on the cover plate are providedwith holes. Bolt connecting pieces sequentially penetrate through the holes and the sleeves to be fixed to the H-shaped upper surface of the H-shaped steel beam. The connection structure solves the problems that in the prior art, connection of prefabricated bottom plates and the steel beam is not good, accordingly the performance of cooperative work is affected and cracks are prone to occurring atjoints of the prefabricated bottom plates. The invention further discloses a connection method of the connection structure of the prefabricated assembly type laminated plates and the steel beam.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a connection structure between a prefabricated and assembled laminated plate and a steel beam, and also relates to a connection method of the above-mentioned laminated plate. Background technique [0002] As the country puts forward the requirements of building industrialization, all kinds of prefabricated floors emerge in endlessly. At present, the floors of buildings generally have problems such as poor overall rigidity, poor stability and earthquake resistance, low load-bearing capacity, and high cost. , It is difficult to take measures at the joints of the floor slabs in the project, resulting in poor sound insulation of the building. [0003] Prefabricated concrete laminated floor is one of the most commonly used floor forms of prefabricated steel structure houses, and it is also the first research content in the floor system. It has good integrity, crack resi...
