Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a modified structure for adding an elevator to the staircase of an existing building. Background Art

[0002] With the intensification of social aging and the increase in demand for barrier-free travel, a large number of multi-storey existing buildings, due to not being equipped with elevators, bring great inconvenience to residents, especially the elderly and people with reduced mobility. However, installing elevators in existing buildings faces many technical challenges: first, traditional elevator installation schemes mostly adopt an independent external shaft, which occupies a large area, has a complicated approval process, and may affect the lighting and appearance of the building, causing neighborhood conflicts. Therefore, there is an urgent need for an elevator installation and modification structure that can minimize the impact on the original building structure, is quick to construct, has high space utilization, and can take into account the rights and interests of each owner on the premise of ensuring convenient use, aesthetics and durability. Contents of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of existing space and technology, and provide a modified structure for adding an elevator to the staircase of an existing building, which has a compact structure, is convenient to install, and has little impact on the main structure of the building and the rights and interests of owners.

[0004] A modified structure for adding an elevator to the staircase of an existing building, comprising a new staircase room, an elevator shaft, a car and a driving system. The key improvement is that the new staircase room is a concave-shaped three-flight staircase structure modified from the original "日"-shaped double-flight staircase, a U-shaped space for accommodating the elevator shaft is formed in the concave-shaped three-flight staircase structure, and the elevator shaft is arranged adjacent to the new staircase room and the entrance corridor platform of the floor; the elevator shaft adopts a modular steel structure frame, which is fixedly connected to the flights of the new staircase room and / or the corridor platform beam in the floor through a plurality of anchoring assemblies; the entrance of the car is in level docking with the floor entrance corridor platform, to achieve level entrance.

[0005] Further, the flights of the concave-shaped three-flight staircase are of reinforced concrete cast-in-place structure or steel structure, and the connection between the new staircase flight and the original platform beam is anchored by means of bar planting or lapping.

[0006] Further, the anchoring assembly comprises a steel structure pressing plate, an expansion bolt and a gasket set, which is used to adapt to the unevenness of the building beam and realize a stable and adjustable connection.

[0007] Further, a sound insulation layer is arranged at the top of the elevator shaft.

[0008] Further, the driving system is traction driving or screw driving, and is arranged at the top or bottom of the shaft.

[0009] Further, the car adopts a center opening door, through door or right-angle opening door design, and the door leaves do not interfere with the normal passage of the new stairwell after being opened.

[0010] Further, an integrated control cabinet is also included, and the integrated control cabinet is embedded on the side wall of the elevator shaft or arranged at a hidden position on the corridor platform of the top floor of the new stairwell. Advantageous Effects

[0011] Compared with the prior art, the advantageous effects of the present utility model are:

[0012] High space utilization: the original "曰"-shaped double-flight staircase is skillfully transformed into a "concave"-shaped three-flight staircase, and an elevator is additionally installed by using the created U-shaped space, which does not need to occupy an additional public area and has no influence on lighting and ventilation of the corridor.

[0013] Safe and reliable structure: only local modification is required for the original staircase structure, and a modular steel structure shaft and special anchoring assemblies are adopted to realize reliable connection with the original building structure.

[0014] Convenient and efficient construction: the flight of stairs can be modified layer by layer, and the construction has little influence on the passage of residents. Modular assemblies of the elevator shaft can be prefabricated in a factory and rapidly assembled on site, which greatly shortens the construction period.

[0015] Strong adaptability: through local modification of the stair flight, the adjustment function of the anchoring assemblies and selection of different driving modes, the present invention can adapt to a variety of existing stairwells with different structures and sizes. Description of Drawings

[0020] To make the purposes, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] As Figure 1 shown, the original standard floor staircase comprises an original stairwell (5), which is arranged in a "曰"-shaped double-flight pattern, and a floor corridor platform (4) is arranged at the lower part thereof.

[0022] As Figure 2 As shown in this embodiment, by locally modifying the staircase structure, the original "日"-shaped double-flight staircase of the original stairwell (5) is changed into a new "concave"-shaped three-flight stairwell (1), thereby creating the U-shaped space required for the elevator hoistway (2). The elevator hoistway (2) is arranged adjacent to the new stairwell (1) and the floor entry corridor platform (4). The flights of the "concave"-shaped three-flight staircase are of cast-in-place reinforced concrete structure or steel structure, and the connection between the new staircase flight and the original platform beam is anchored by means of bar planting or lapping.

[0023] As Figure 3 shown, the drawing shows the structure where the car (3) is leveled and docked with the floor entry corridor platform (4). A sound insulation layer (8) is arranged at the top of the elevator hoistway (2). In this embodiment, the driving system can be selected as traction driving or screw driving, and is arranged at the top or bottom of the elevator hoistway (2); the car (3) can adopt a double-opening door design, a through-door design or a right-angle door opening design, and the door leaves do not interfere with the normal passage of the new stairwell (1) after being opened. Meanwhile, an integrated control cabinet (9) is embedded and installed at a hidden position on the side wall of the elevator hoistway (2) or the top-floor corridor platform (4).

[0024] As Figure 4 shown, the drawing shows the specific structure for anchoring the elevator hoistway with the platform beam. The modular steel structure frame of the elevator hoistway (2) is fixedly connected with the flights of the new stairwell (1) and / or the corridor platform beam (7) in the floor through a plurality of anchoring assemblies (6). The anchoring assembly (6) specifically comprises a steel structure pressure plate (61) connected with the steel structure frame, an expansion bolt (62) connected with the building structure and a gasket set (63).
