Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building structures, and particularly relates to an elevator installation method for old community reconstruction. BACKGROUND

[0002] With the development of new city construction, the reconstruction of old communities is imperative, and the reconstruction of old communities in many first-tier cities is relatively complete. However, the installation of elevators in the reconstruction of old communities is a relatively complex and difficult problem.

[0003] Firstly, the cost of installing an elevator is relatively high. Secondly, users of low floors such as the first floor and the second floor of the old community are mostly opposed to the installation of elevators.

[0004] The existing technology of external elevators has its own characteristics, whether it is the installation form with or without a foundation pit or the arrangement form of a corridor bridge, but it does not consider the influence of the installed elevator on the original old house seismic performance.

[0005] With the development of science and technology, the safety of elevators is also getting higher and higher, and the elevators are also regularly maintained, and the accident rate is also getting lower and lower. However, the phenomenon of elevator out of control leading to rapid descent still exists.

[0006] Therefore, it is urgent to develop an elevator installation method for old community reconstruction to solve the problems in the prior art. SUMMARY

[0007] The purpose of the present application is to provide an elevator installation method for old community reconstruction, which can facilitate the installation of elevators in buildings without elevators, improve safety, and has a simple structure and is convenient to use, so as to solve the problems in the background art.

[0008] To achieve the above purpose, the present application provides the following technical scheme:

[0009] An elevator installation method for old community reconstruction is provided, which is located at the wall of a half-floor staircase and comprises an external elevator, an elevator shaft arranged on a foundation pit, and a machine room arranged on the elevator shaft. The elevator shaft is provided with a safety bladder fixedly connected thereto, and the elevator car is slidingly connected in the safety bladder, and a plurality of sliding members are arranged between the safety bladder and the car.

[0010] As a further scheme of the present application, the sliding member is a ball, which is rollingly connected to the safety bladder and in contact with the car. The ball is used as the sliding member, which can effectively reduce the influence of contact friction.

[0011] As a further scheme of the present application: the ball is provided with a plurality of small holes in communication with each other, the ball is made of high chromium steel material, and the small holes are filled with thermal expansion material. In this scheme, a plurality of communicating small holes are arranged in the ball, and the small holes are filled with thermal expansion material. In the event of elevator failure, such as rapid descent, under the action of increased speed, the ball is heated and the temperature rises, causing the thermal expansion material inside the ball to expand, thereby increasing friction and achieving a deceleration effect, thereby improving the safety of the elevator.

[0012] As a further scheme of the present application: the safety liner comprises an alloy steel layer sleeved outside the carbon steel layer, a compression-resistant pad layer is arranged between the alloy steel layer and the carbon steel layer, a weight-reducing cavity is arranged in the carbon steel layer, and a clamping groove matched with the sliding member is arranged on the alloy steel layer. The safety liner and the external elevator tower structure are fixedly installed, the elevator car and the safety liner are slidingly matched, and a plurality of balls are arranged between the car and the safety liner. The inner and outer main bodies of the safety liner are metal products, i.e. the carbon steel layer and the alloy steel layer, for ensuring sufficient rigidity, wherein the compression-resistant pad layer is a pressed glass fiber, which has good insulation and heat insulation, reduces safety accidents caused by electric leakage, and effectively insulates heat.

[0013] As a further scheme of the present application: the weight-reducing cavity comprises a honeycomb-shaped sheet metal, and the honeycomb holes of the sheet metal are filled with carbon fibers. The honeycomb-shaped sheet metal is arranged in the weight-reducing cavity, and the honeycomb holes are filled with carbon fibers. The honeycomb-shaped design is used to ensure the strength of the structure, and can effectively reduce the weight of the safety liner.

[0014] As a further scheme of the present application: a friction-reducing pad fixedly matched with the clamping groove is arranged in the clamping groove, and the friction-reducing pad is a bearing bush. The bearing bush is arranged in the clamping groove for fixed matching, for reducing friction and preventing the thermal expansion material in the ball from expanding during normal operation.

[0015] As a further scheme of the present application: a plurality of vibration-damping feet matched with the car are arranged at the bottom end of the car. The vibration-damping feet are arranged for damping when the elevator descends to the bottom, for reducing the rigid force and the vibration sensation.

[0016] As a further scheme of the present application: the vibration-damping foot comprises an upper end portion and a lower end portion, the upper end portion is fixedly installed at the bottom end of the car, a sealed air bag is arranged between the upper end portion and the lower end portion, a waist ring is sleeved in the air bag, and the waist ring divides the air bag into two air bubbles of the same size and in communication with each other. The vibration-damping foot realizes damping effect through the air bag, and the waist ring is used to improve airflow guidance and prevent the air bag from being uniformly stressed and ruptured.

[0017] As a further scheme of the present application: a valve core in communication with the air bag is arranged on the lower end portion. The valve core is arranged to facilitate air supplementing of the air bag during regular maintenance of the elevator, and to ensure air pressure.

[0018] Compared with the prior art, the present application has the advantages that: the elevator door is arranged at the wall of the half-floor stairway of the adjacent floor of the building without elevator, the elevator is arranged outside the building, the construction time and cost of the added elevator can be effectively reduced, and the safety performance of the car is improved by arranging the safety valve in the elevator.

[0019] Other features and advantages of the present application will be described in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF DRAWINGS
