Connection structure of prefabricated slab and bay beam and its construction method

Abstract

The invention discloses a connection structure between a prefabricated slab and a bay beam, comprising: a prefabricated slab; a bay beam supported on the bottom of the prefabricated slab, and a corner is defined between the side of the bay beam and the bottom surface of the prefabricated slab; a reinforcement component is located on the At the corner, the reinforcement assembly has a top plate and a side plate, the top plate is fixedly engaged with the bottom surface of the prefabricated panel, and the side plate is fixedly engaged with the side of the bay beam. The invention also provides a construction method for the connection structure of the prefabricated slab and the bay beam. The connection structure between the prefabricated slab and the bay beam provided by the present invention can strengthen the joint strength between the prefabricated slab and the bay beam through the arrangement of the reinforcement components, so as to improve the integrity of the prefabricated slab and the bay beam, and can improve the strength of each lateral force-resistant member. Cooperate with the deformation ability, reduce the interstory displacement of the structure, so as to avoid the partial or overall collapse of the masonry structure floor as much as possible, and obtain better earthquake resistance; moreover, the construction method of the connection structure between the prefabricated slab and the bay beam is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a connection structure of a prefabricated plate and a bayonet beam and a construction method thereof, which can strengthen the integrity between the prefabricated plate and the bayonet beam. Background technique [0002] According to the analysis of the collapse mechanism of masonry structures in recent earthquakes with an earthquake intensity of not less than 7 degrees and the analysis and summary of the seismic survey results of existing masonry structures in China, it can be seen that the most fundamental cause of the collapse of masonry structures is the prefabricated floor. Due to the characteristics of the materials used and the weak lap joint between the prefabricated slab and the bayonet beam, the structural integrity cannot meet the corresponding requirements. The masonry structure has inherent factors that are not conducive to earthquake resistance due ...

[0002] According to the analysis of the collapse mechanism of masonry structures in recent earthquakes with seismic intensity not less than 7 degrees and the analysis and summary of the seismic investigation results of existing masonry structures in China, it can be seen that the most fundamental reason for the collapse of prefabricated floors of masonry structures It is attributed to the characteristics of the materials used and the weak lap joint between the prefabricated slab and the bay beam, and the structural integrity cannot meet the corresponding requirements

However, due to its own building layout requirements, the masonry structure has inherent factors that are not conducive to earthquake resistance.
