Horizontal seam U-shaped closed rib junction structure of assembled shear wall structure

Abstract

The invention discloses a horizontal seam U-shaped closed rib junction structure of an assembled shear wall structure, comprising an upper-layer outer wall prefabricated shear wallboard (1), a lower-layer outer wall prefabricated shear wallboard (2), an upper-layer inner wall prefabricated shear wallboard (16), a lower-layer inner wall prefabricated shear wallboard (17), U-shaped closed ribs (5), a horizontal reinforcing rib (6) and filled cast-in-place concrete (13), wherein the U-shaped closed ribs adopting the upper-layer outer wall prefabricated shear wallboard, the lower-layer outer wall prefabricated shear wallboard, the upper-layer inner wall prefabricated shear wallboard and the lower-layer inner wall prefabricated shear wallboard are staggered and are in lap joint to form an annular ring; the horizontal reinforcing rib is arranged in the annular ring to reliably connect the vertical reinforcing steel bars of the assembled shear wall; and the filled cast-in-place concrete of a horizontal seam (7) realizes the purpose that the resistance to shear of the horizontal seam is equivalent to the cast-in-place concrete shear wall. The whole prefabricated assembled shear wall can be reliably connected with the shear wall and a floorslab, the whole prefabricated assembled shear wall performance can be ensured, and the horizontal seam U-shaped closed rib junction structure has the advantages of simple form and material conservation and is convenient to construct.

Description

technical field [0001] The invention relates to a U-shaped closed rib connection structure of horizontal joints of an assembled shear wall structure, belonging to the technical field of assembled shear wall structures in construction engineering. Background technique [0002] With the acceleration of the process of "building industrialization and housing industrialization" in my country, the assembled shear wall structure will be more and more widely used in the middle and high-rise residential buildings in my country. The overall shear wall is formed by means of layered prefabrication and on-site assembly. Whether the connection structure of the horizontal joints of the assembled shear wall is reasonable will directly affect the overall performance of the structure and the ability to resist rainwater leakage. [0003] For the horizontal joints of assembled shear walls, the known connection structure, or only additional vertical connecting steel bars pass through the flat hor...

Problems solved by technology

[0005]Technical problem: In order to solve the existing horizontal joint connection structure of the assembled shear wall structure, the horizontal shear difference affects the overall performance of the structure, the connection between the floor slab and the prefabricated wall panel is weak, Due to the low construction efficiency of the cast-in-place ring beam at the intersection of the floor wall board and the floor board and the difficulty in realizing the integrated construction of external wall insulation, the present invention provides a U-shaped closed rib connection structure for the hor
