Multi-storey residential additionally-mounted elevator prefabricated assembly type pit foundation device in cold region

Abstract

The invention discloses a multi-storey residential additionally-mounted elevator prefabricated assembly type pit foundation device in the cold region. The prefabricated assembly type pit foundation device comprises a foundation bearing platform, the foundation bearing platform is poured in a foundation pit, and a concave table is formed in the foundation bearing platform through the middle which is fixed through mortar; and lifting rings used for lifting are welded on the inclined surfaces of the outer sides of the concave table, the four corners and the center of the concave table are also meshed with four-column steel bars and vertical steel bars which are vertically upward, and the concave table is connected with a side wall body through the vertical steel bars correspondingly. According to the multi-storey residential additionally-mounted elevator prefabricated assembly type pit foundation device in the cold region, a pit foundation is novel in design, simple in structure and convenient to construct and install, and the on-site construction has few situations of disturbing residents; the mode of prefabricating components and then carrying out on-site assembly is achieved so that the construction period can be effectively shortened, the cost can be reduced, and the interference on the life of the residents can be reduced; and the waterproof, cold-proof and warm-keeping problems of existing multi-storey residential additionally-mounted elevator pit foundations in the super-cold and cold regions are solved, the design is reasonable, the structure is simple, the assembly isconvenient, and favorable conditions are created for improving the construction quality and the economic benefit.

Description

technical field [0001] The invention relates to a prefabricated and assembled bottom pit for adding an elevator, in particular to a prefabricated and assembled bottom pit foundation device for adding an elevator to a multi-storey residence in a cold area. Background technique [0002] With the acceleration of population aging process and the improvement of residents' living standards, the demand for installing elevators in existing multi-storey residences will also increase day by day.
