Joint of fabricated precast shear wall and laminated slab connected with fabricated precast shear wall by combined grouting sleeves

Abstract

The invention discloses a joint of a fabricated precast shear wall and a laminated slab connected with the fabricated precast shear wall by combined grouting sleeves. The combined grouting sleeves are arranged at the joint. Each combined grouting sleeve comprises a first section sleeve body and a second section sleeve body; the top ends of the first section sleeve bodies are connected with the bottom ends of the second section sleeve bodies; the bottom ends of the first section sleeve bodies are connected on the top ends of vertical steel bars in the precast shear wall and completely pre-buried in the top ends of the precast shear wall, and the second section sleeve bodies are pre-buried in post-poured concrete laminated layers; the vertical steel bars extend downward out of the precast shear wall on the last storey, the vertical steel bars are inserted in the second section sleeve bodies from the top ends of the second section sleeve bodies and extend into the first section sleeve bodies; and mortar discharging pipes are arranged on the upper portions of the second section sleeve bodies, and grouting pipes are arranged on the lower portions of the first section sleeve bodies. The combined grouting sleeves serve as connecting pieces of the shear wall on the upper layer and the shear wall on the lower layer. Shear wall members form plastic hinges at the bottom. The shear wall and the precast slab form the joint through mutual connection and bonding occlusion among the sleeve bodies, steel bar meshes and post-poured concrete, and the integrity and anti-seismic performance of the joint are improved.

Description

technical field [0001] The invention relates to an assembled prefabricated shear wall and laminated plate joint, in particular to an assembled prefabricated shear wall and laminated plate joint connected by a combined grouting sleeve. Background technique [0002] Prefabricated prefabricated reinforced concrete structures have more practical applications and more mature technical research in developed countries such as Europe, America and Japan. In recent years, the country has developed green buildings, vigorously developed prefabricated buildings, and promoted the transformation and upgrading of the construction industry. With the acceleration of the process of "construction industrialization and housing industrialization" in my country, the application of prefabricated shear wall structures has become increasingly widespread, and the domestic practical application and theoretical research on prefabricated buildings has continued to deepen. [0003] However, domestic rese...
