3, metal construction combined shaft frame favourable solution ventilation and penetrating light problem is adopted.Metal construction derrick does not have fully enclosed well enclosure civil engineering, and the enclosing to cover of derrick surrounding can take mode flexibly, makes hoistway retain certain ventilation and penetrating light function.Derrick encloses and covers materials such as can adopting case hardened glass, cleading, louver and enclose and cover or adopt multiple material to mix to enclose and cover, case hardened glass encloses and covers and can carry out heat insulation process by coating, make it both can heat-insulating sound-insulating, waterproof of keeping off the rain, prevent foreign material from entering, there is again certain light transmission function, thus the impact of lift-mounting on low layer resident family ventilation and lighting is reduced to minimum.
4, metal construction combined shaft frame is adopted can to improve the installation quality of elevator.Because metal construction derrick is produced in factory normalization, the working accuracy of derrick can control, and therefore can improve setting accuracy and the installation quality of elevator, thus the service life of the safety of favourable raising elevator operation and prolongation elevator.
5, employing pit prefabricating technique efficiency is high, the duration is short, little on resident family's impact.Because pit hole of the present invention body can adopt reinforced concrete precast member, therefore favourable raising operating efficiency, shorten the construction period, the impact of pit construction on the daily life of place building resident family can be reduced.
