Caisson type composite shear wall underground garage and its construction method

Abstract

The invention discloses a caisson type superimposed shear wall underground garage and a construction method thereof, belonging to the construction field. It includes the outer wall surrounded by laminated shear walls, the outer wall is provided with multi-layer laminated beams and frame columns, the laminated shear wall is provided with buttress columns, the laminated shear walls, buttress columns, multiple The layered composite beams and frame columns are connected into one structure, and the integrated structure is sunk to the specified elevation in the ground through caisson construction; the composite beams at the bottom layer are cast-in-place concrete to form a reinforced concrete floor, and the composite beams on other floors are A concrete laminate floor is provided and poured with concrete. Each prefabricated component of the present invention is light in weight, convenient in transportation and hoisting, low in cost, saves formwork, and has faster construction speed; construction by caisson method avoids large-area excavation of foundation pits, reduces earthwork excavation volume, avoids foundation pit support, and reduces Due to the impact of construction on the surrounding environment, residents' lives and other buildings, there are obvious advantages in building underground garages in areas of existing buildings and between buildings.

Description

technical field [0001] The invention relates to the field of construction, in particular to a caisson type laminated shear wall underground garage and a construction method thereof. Background technique [0002] With the expansion of city scale and the improvement of residents' living standards, the number of family cars in cities also continues to increase. As urban ground space is becoming less and less, building underground garages has become a trend. However, there are various problems in the existing underground garage construction methods, especially in the area of ​​existing buildings or when building underground garages between buildings, the surrounding buildings restrict the construction very obviously, which affects the progress of the project, the quality of the project and the construction of the underground garage. Post-project maintenance caused many difficulties. [0003] The current underground garages are mainly divided into the following types according t...

AI Technical Summary

Problems solved by technology

At present, the composite shear wall technology has been applied in prefabricated buildings, but there is no research on the combination of composite shear wall and caisson technology in the construction of underground garages.
