Embodiment Construction

[0044] The embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0045] Such as figure 1 with figure 2 As shown, an elevator hoistway in an existing building of the present invention includes a foundation 100 on which a hollow and upper and lower opening preform body 1 is successively superimposed and connected in a vertical direction. The preform body 1 is made of steel The upper connecting seat 3 and the lower connecting seat 4 are made of steel, and the upper connecting seat 3 and the lower connecting seat 4 on the same preform body 1 are made of one piece of concrete. Reinforcement for fixed connection. Such as Figure 21 As shown, at the upper end of the preform body 1 located on the top layer of the elevator hoistway, a capping structure 200 is provided, and a corresponding hook 201 is provided in the capping structure 200.

[0046] Each preform body 1 is provided with an elevator exit / entrance 2 on one side, and the uppe...

Abstract

The invention discloses a hoistway for additional mounting of an elevator in an existing building. The elevator hoistway comprises a foundation and prefabricated piece bodies connected sequentially on the foundation in an overlaid mode in the vertical direction. The prefabricated piece bodies adopt steel bar concrete structures, are hollow and opened up and down. Prefabricating is conducted in advance outside a site. The two prefabricated piece bodies can be aligned through an upper butt joint structure and a lower butt joint structure to be mounted rapidly. The hoistway has the characteristics of being simple in structure, safe, reliable and high in mounting efficiency in site.

Description

[0001] 【Technical Field】 [0002] The invention relates to a building structure, in particular to an existing building with an elevator shaft. [0003] 【Background technique】 [0004] The demand for installing elevators in existing buildings is increasing day by day. Since there is no special elevator hoistway for installing elevators in existing buildings, an outdoor hoistway needs to be added for elevator installation and operation. The outdoor hoistway in the prior art generally uses a steel structure derrick or a brick wall reinforced concrete structure hoistway. If the brick wall reinforced concrete structure hoistway is directly built on the construction site, it is not economical and labor-intensive, and takes up a large space. However, the existing steel structure hoistway is made by integral field welding or on-site tailored welding of prefabricated steel components. The height is relatively high. Because the elevator hoistway requires high-altitude welding technology, the e...
