Elevator installed in existing building

Abstract

The invention discloses an elevator installed in an existing building. The inner portion of a base of a bottom pit is provided with a bottom section steel structure, the steel at the upper portion of the bottom section steel structure is provided with at least one section of middle section steel structure, and the upper portion of the middle section steel structure is provided with a top section steel structure. At least one upright column in the bottom section steel structure, at least one upright column in the middle section steel structure and at least one column in the top section steel structure are all provided with flanging of heavy auxiliary guide rail as integrated mineral powders. The bottom section steel structure, the middle section steel structure and the top section steel structure forms steel structure hoistway of the elevator, a carriage system is arranged in the steel structure hoistway through a main orbit, the upper end of the top section steel structure is provided with a mainframe and a plurality of guide wheels through a load bearing beam, and the carriage system moves up and down driven by the mainframe and the guide wheels. A portion of the steel structure is used as a counterweight rail, no guide rail support is needed, the elevator hoistway is manufactured by sections, the installation of the steel structure hoistway and the elevator is conducted at the same time at the site, time and effort are saved, and construction period is reduced.

Description

technical field [0001] The invention belongs to the technical field of elevator processing, and in particular relates to a ladder installed in an existing building. Background technique [0002] Since high-rise buildings have only been widely popularized in the last ten years, elevators have also become popular. At present, there are still large-scale old residential buildings and small high-rise buildings without elevators. The layout of the residential area is compact and the supporting community services are lacking. At the same time, these houses are mostly middle-aged and elderly people, and the lack of elevators brings a lot of inconvenience to their lives. The existing installation of elevators is to first install the steel structure shaft independently, and then extend the counterweight guide rail bracket in the shaft, install the guide rail bracket, and then Install the counterweight rail.

[0002] As high-rises have only been widely popularized in the last ten years, elevators have also become popular. At present, there are still large-scale old residential buildings and small high-rise residential buildings without elevators. The layout of the residential area is compact and the supporting community services are lacking.

At the same time, these houses are mostly middle-aged and elderly people, and the lack of elevators brings a lot of inconvenience to their lives. The existing installation of elevators is to first install the steel structure shaft independently, and then extend the counterweight guide rail bracket in the shaft, install the guide rail bracket, and then Install the counterweight rail

The installation and adjustment of counterweight guide rails and brackets are cumbersome and consume a lot of man-hours. At the same time, since the steel structure is generally assembled with profiles, the width direction of the steel structure columns and crosspieces occupy the space of the hoistway, which reduces the net size of the hoistway and cannot be used effectively. In the hoistway space, the traditional elevator counterweight (balance weight) structure is composed of a counterweight frame and a counterweight block. Elevators not only need to be installed in sequence, but also take more construction time and generate more costs; the existing elevator car is assembled into a box structure from the car wall, car roof, and the bottom of the foot. During the use of the elevator, personnel must always stand In the car, when the landing is high or the elevator is running at a low speed, the residence time in the elevator is prolonged, which is prone to fatigue. The existing elevator space integration function is single, and the efficiency of the space is not used to the extreme. At the same time, taking into account the existing situation Emergency use in response to power outages. At present, elevators are basically handled by supporting emergency power generation equipment.
