Assembled steel structure lift shaft

Abstract

The invention discloses an assembled steel structure lift shaft. The assembled steel structure lift shaft comprises a plurality of parallel longitudinal beams arranged in a surrounding manner to forma rectangular column and a plurality of cross beams, and the cross beams are connected between the longitudinal beams, so that the longitudinal beams are connected to form a whole. The height direction of the shaft is the vertical direction, each longitudinal beam comprises a plurality of longitudinal connecting units, and connecting assemblies, and the connecting assemblies are connected betweenthe longitudinal connecting units, so that every two vertically adjacent longitudinal connecting units are fixedly connected. The cross beams are perpendicular to the longitudinal beams and are connected between the longitudinal connecting units adjacent left and right. The product structure is extremely easy to machine, the technological requirement is simple, operation is easy, the machining time can be greatly shortened, and the machining period can be shortened. No large crane is needed during on-site mounting, construction conditions can be met through small cranes, retrofitting space exists, and a lift steel structure and a lift can be retrofitted.

Description

technical field [0001] The invention relates to the elevator industry, in particular to an assembled steel structure elevator shaft. Background technique [0002] The existing elevator installation structures include rectangular tube welding technology and modular installation. The welding and installation of rectangular pipes requires on-site welding, which requires a long time of work. There is welding pollution on site, which has certain safety hazards and seriously affects the lives of residents on site. However, due to the large volume of the product, most sites cannot meet the construction requirements, such as the access of cranes. Moreover, the product processing cycle of the modular installation method is long, the process requirements are complicated, and the product cost is high. Contents of the invention [0003] The object of the present invention is to provide an assembled steel structure elevator shaft whose structure is extremely easy to process and can be...
