Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to a prefabricated external elevator shaft. Background Technology

[0002] With the increasing demand for adding elevators to existing buildings, traditional elevator shafts are made of concrete and are connected to the original building, which can easily damage the facade and the building itself. Moreover, the traditional elevator shaft construction method has many inconveniences, such as long construction period and great impact on the main structure of the building.

[0003] Patent application CN201611021855.8 discloses a prefabricated building elevator shaft tool-type vertical traffic staircase, including a structural frame and a staircase assembly connected to the structural frame. Multiple wall-connecting components are provided on the outer periphery of the structural frame. Pre-embedded components corresponding to the wall-connecting components are pre-embedded in the elevator shaft. The tool-type vertical traffic staircase is connected to the corresponding pre-embedded components through the multiple wall-connecting components and installed in the elevator shaft. The staircase assembly forms a building construction passage in the elevator shaft.

[0004] However, the aforementioned patent is for a staircase structure, which cannot meet the needs of old building renovation and elevator installation. Therefore, developing a prefabricated external elevator shaft structure to improve construction efficiency and reduce the impact on the main building structure is of great practical significance.

[0040] The elevator shaft is located on the ground outside the building, with multiple bolts pre-embedded to fix the lowest floor unit structure.

[0041] All layer unit structures are steel frame structures, arranged vertically in sequence.

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

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

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

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

[0052] (4) Compared with traditional concrete-installed elevator structures, it has higher economic efficiency and durability. The factory-prefabricated components are of reliable quality, reducing the uncertainty and quality risks of on-site construction, and further reducing construction costs.

[0053] (5) The alternating layer units feature two connection methods (detachable connection and welded fixed connection), allowing the elevator shaft to adapt to different building structures and usage requirements. The design of the connecting corridor components makes the connection between the elevator shaft and the building more flexible, adapting to buildings of different heights and locations.
