Description

TECHNICAL FIELD

[0002] For existing residential elevator installation engineering, the elevator structure form and structure system commonly used at present mainly have three kinds: steel frame structure (steel frame structure) Figure 1 ), reinforced concrete shear wall structure (reinforced concrete shear wall structure) Figure 2 ) and reinforced concrete frame structure (reinforced concrete frame structure) Figure 3 ).

[0003] The steel frame elevator structure (steel frame elevator structure) Figure 1 is more common. The structure form adopts square steel pipe or "H" shaped steel section, and is mostly six-column structure. Steel column and steel beam are welded and connected on site, and are gradually increased to the roof. After the structure construction is completed, the installation construction of side wall and elevator track and the like is carried out. The main shortcomings of this method are that there are many welding positions on site, and the construction quality is difficult to control; there are many sequential construction processes, and the construction period is relatively long; scaffolding needs to be set up, and there is a certain degree of disturbance to the residents; the steel structure has poor fire resistance, and the elevator shaft fireproofing problem is difficult to solve; and the steel structure has relatively poor economy.

The construction mode of these two structures is the same as that of conventional reinforced concrete structure, and the shaft wall and beam are poured layer by layer until the roof. After the main structure reaches the strength, the masonry partition wall (reinforced concrete frame structure shaft), plastering decoration and equipment installation construction can be carried out. The main shortcomings of this method are that there are many cast-in-place concrete wet operations, and the construction period is long; scaffolding needs to be set up, and has a greater impact on the residents' life; the demand for single-layer concrete is small, and it is not suitable for the purchase and transportation of ready-mixed concrete; the construction formwork and steel reinforcement yard have certain requirements for the on-site construction space.

Although this structure can avoid the problem of cast-in-place concrete, it also has the shortcomings of large self-weight of elevator standard section, inconvenient on-site hoisting, large size of single section, and too many transportation conditions.
