Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular, to a shaft structure for installing an elevator in an old building. Background Art

[0002] At present, some old residential buildings above the fourth floor are not equipped with elevators. For the elderly living in these residential buildings, it is rather inconvenient to go up and down the stairs. Therefore, many old residential buildings are equipped with elevators to facilitate the activities of the elderly.

[0003] The existing Chinese patent with the publication number CN219469391U discloses a shaft structure for installing an elevator in an old building, including a shaft frame. The shaft frame includes prefabricated unit steel frames and connecting members. A plurality of steel frame units are arranged vertically in a stacked manner, and two adjacent prefabricated unit steel frames up and down are connected by connecting members; the prefabricated unit steel frame includes four vertical square tubes and eight cross beams. The four vertical square tubes are distributed in a rectangular array, and two cross beams are connected between two adjacent vertical square tubes. A plurality of first holes are respectively provided on the side walls of the vertical square tubes near the top and bottom; the connecting member includes a connecting pipe. A convex limiting flange is provided on the side wall of the connecting pipe, and a plurality of second holes are provided on the side wall of the connecting pipe; the pipe body of the connecting pipe above the limiting flange is inserted into the vertical square tube of the prefabricated unit steel frame on the upper side, and the pipe body of the connecting pipe below the limiting flange is inserted into the vertical square tube of the prefabricated unit steel frame on the lower side, which can solve the problem of the cumbersome and complex construction process of installing an elevator in an old residential building.

[0004] However, the above shaft structure has the following disadvantages: The device can quickly install the unit steel frames together by setting the prefabricated unit steel frames and connecting members. However, the connecting members of the device cannot adjust the length, so the height of the unit steel frames cannot be adjusted. If a height difference is found during the actual construction process, it is very complicated and troublesome to adjust according to the actual situation, which seriously reduces the construction efficiency.

[0005] Therefore, we propose a shaft structure for installing an elevator in an old building to solve this problem.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content
