[0002] Against the backdrop of the increasing demand for installing elevators in existing buildings, traditional elevator shafts all use cast concrete structures, which are connected to the original buildings and can easily cause damage to the facades and building bodies of old buildings. In addition, traditional elevator shaft construction methods have many inconveniences, such as long construction periods and significant impacts on the main building structure.

[0003] The patent with application number CN201611021855.8 discloses a tool-type vertical traffic staircase for an assembled building elevator shaft, which includes a structural frame and a staircase assembly connected to the structural frame. A plurality of wall-connecting components are arranged on the periphery of the structural frame, and pre-embedded components corresponding to the wall-connecting components are embedded in the elevator shaft.

[0048] The beneficial technical effects of this assembled external elevator shaft are:

[0049] (1) The prefabricated structure is adopted, and each component is prefabricated in the factory and installed on site, which greatly shortens the construction period. The embedded bolts and detachable connection method make the installation process more convenient and reduce the on-site construction time and labor.

[0050] (2) The external elevator shaft has little impact on the main building. It does not occupy the internal space of the building, which reduces the need for changes to the main structure of the building. One end of the corridor component is welded to the side wall of the building, and the other end is detachably connected to the floor unit structure. This connection method ensures stability while reducing damage to the main building.

[0051] (3) The structure is stable and reliable. The overall stability of the elevator shaft is ensured through the rational design of connection components, such as the back column connection component and the back column shear component. The upper and lower adjacent back columns and front columns are detachably connected through the shear component and the support beam component, which enhances the connection strength and shear resistance between the components.

[0052] (4) Compared with the traditional concrete elevator structure, it has higher economy and durability. The quality of prefabricated components in the factory is reliable, which reduces the uncertainty and quality risk of on-site construction and further reduces construction costs.

[0053] (5) The alternating distribution of the two connection methods of the alternating layer units (detachable connection and welded fixed connection) allows the elevator shaft to adapt to different building structures and usage requirements. The design of the corridor component makes the connection between the elevator shaft and the building more flexible and can adapt to buildings of different heights and locations.
