Description

A prefabricated structure elevator shaft and elevator

technical field

The invention belongs to the field of elevator equipment, in particular to an elevator shaft and an elevator with an assembled structure.

Background technique

With the acceleration of population aging process and the improvement of residents' living standards, the demand for installing elevators in multi-storey buildings will also increase day by day. The multi-storey building has been built to install elevators because there is no well design in advance. The usual way is to add an outdoor shaft for elevator installation and operation. However, the existing steel structure wells are formed by integral on-site welding or on-site tailor-welding of prefabricated steel components, which requires high-altitude welding technology. The entire construction process is carried out outdoors, which is greatly affected by the climate and environment, and the construction period is very long. Often more than 60 days, the long-term construction noise is loud, and disturbance incidents often occur. Another kind of steel structure hoistway is a fully assembled type, all of which are made of a single prefabricated steel component, which is fastened with bolts on site. Although this kind of steel structure hoistway saves the trouble of welding, there are many steel components and the structure is relatively complicated, which requires high assembly of steel components. The installation quality, operational reliability and riding comfort of the elevator in the shaft are still very long, so the construction period is still very long and the installation cost is also high. In addition, the construction of the existing steel structure shaft is completely separated from the installation of the elevator. Usually, the elevator is installed and debugged after the construction of the shaft. Therefore, the total time for the installation of the outdoor elevator is very long, and the labor costs on site are also large, resulting in The total cost of installing elevators increases, and many multi-storey buildings have been built with elevators and therefore cannot be realized.

Aiming at the technical status and development obstacles of adding elevators at present, a modular steel structure hoistway integrated elevator (CN 102180395B) has been developed. The integrated elevator, including the steel structure shaft and all parts of the shaft, are manufactured, processed and assembled in the workshop of the factory, and only modular hoisting and debugging are carried out on the elevator site. However, the hoistway of this kind of modular steel structure is still transported in the form of a larger frame when it leaves the factory, which still takes up a large transport space and is extremely inconvenient to transport.

Contents of the invention

The object of the present invention is to provide a prefabricated structure elevator shaft with less occupied height, the main way of which is to adopt a sheet structure.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solution: an elevator shaft with an assembled structure, the elevator shaft includes a plurality of piece-type side frames and connectors for fixing and connecting each of the piece-type side frames. The two piece side frames are connected end to end in sequence to form the elevator shaft or to form segments of the elevator shaft, and a plurality of the segments are sequentially spliced to form the elevator shaft, and the connecting piece is connected between the piece side frames or between the segments.

Optimally, the sheet-type side frame is flat or L-shaped as a whole, and the elevator shaft includes at least two pieces of the sheet-type side frame, and the sheet-type side frame includes two side columns connected to the side columns The beams between them and the reinforcing beams connected between the side columns, the connecting parts are arranged on the side columns.
