Novel home elevator shaft

Abstract

The invention discloses a novel home elevator shaft. The novel home elevator shaft comprises a prefabricated foundation pit and an assembly shaft frame, wherein the prefabricated foundation pit comprises a split base plate and a base, the base plate is of a concrete structure which is precast and made in an elevator position on site, the base is of a reinforced concrete structure which is precastand made off site, the base is placed on the base plate after ground leveling, and the base and the base plate are connected by secondary concrete pouring; and the assembly shaft frame is a space frame formed by connecting a car roof, a plurality of cross beams and four combined stand columns through threaded parts, each combined stand column comprises a plurality of auxiliary columns, every two vertically adjacent auxiliary columns are connected through a node assembly, and all the node assemblies are arranged in planes with different heights. The novel home elevator shaft has the effects ofbringing convenience in hoisting and transportation of the shaft frame, being high in bearing cavity, short in on-site working time of the foundation pit, environmentally friendly and hygienic and isnot prone to seepage.

Description

technical field [0001] The invention relates to the field of home improvement elevators, in particular to a novel home improvement elevator shaft. Background technique [0002] The traditional home improvement elevator includes a foundation pit, a derrick, and a car that moves up and down. The foundation pit is excavated on site, and steel bars are installed on site and poured on site. The derrick is pre-welded in the factory or welded on site. The disadvantages are: 1. , the maintenance time after the pouring of the foundation pit is about 28 days, the construction period is long, easy to seepage, and not environmentally friendly; and the foundation pit needs to be protected, which makes it inconvenient for people in the area to travel, and there are potential safety hazards; second, the way of pre-welding in the factory, The derrick is bulky, difficult to hoist and transport, and unsafe; third, the method of on-site welding has its defects: large operating area, long const...
