Description

Technical Field

[0001] The utility model belongs to the technical field of elevator shaft structures, and in particular relates to an elevator shaft structure provided with upper and lower shutters, an observation window and a protective shed. Background Art

[0002] Elevator shafts are generally designed inside buildings, occupying a certain floor area, relying on the main body of the building or built inside, and the elevator and shaft are located inside the building. However, in some buildings such as old residential buildings and villas, elevators were not taken into consideration at the beginning of the design. With the maturity and iteration of elevator technology, the construction cost has gradually decreased. These buildings sometimes need to install elevators. The installed elevator shafts generally need to be designed separately and installed outside the existing buildings.

[0003] When adding elevators to existing buildings in the prior art, the elevator shaft usually adopts a closed structure with only ventilation holes at the top, and the outer wall of the elevator shaft is usually not equipped with anti-falling facilities; therefore, the prior art mainly has the following disadvantages:

[0004] 1) The elevator shaft is not ventilated and the temperature is high in summer. When the temperature in the elevator shaft exceeds 40 degrees Celsius, the electrical components in the elevator control system will overheat, triggering the protection mechanism, causing the elevator to stop responding to external commands and trapping passengers in the car;

[0005] 2) The outer protective walls (glass, plates, etc.) of the elevator shaft are at risk of cracking and falling, causing injury, posing a safety hazard. Utility Model Content

[0006] The technical problem to be solved by the utility model is: in view of the deficiencies in the prior art, an elevator shaft structure is provided with upper and lower shutters, observation windows, and a protective shed. By arranging shutters and screens at corresponding positions on the upper and lower parts of the elevator shaft, the temperature in the shaft can be effectively reduced to maintain a good elevator working environment. By arranging a steel-concrete composite protective shed outside the shaft, it is possible to avoid the outer protective walls and components of the shaft from falling and injuring people, thereby improving safety.

[0007] The technical solution adopted by the utility model to solve the above technical problems is:

[0008] An elevator shaft structure with upper and lower shutters, observation windows and protective sheds, comprising: an elevator shaft frame 2 installed on the outside of an existing building main body 10, the outer wall of the elevator shaft frame 2 is provided with a glass curtain wall 1, the front and left and right sides of the bottom of the elevator shaft frame 2 are provided with anti-collision walls 4, and the left and right sides of the bottom of the elevator shaft frame 2 are also provided with elevator exits 11; shutters 1 3a are installed on the front and left and right sides of the top of the elevator shaft frame 2, and shutters 2 3b that are compatible with the size of the shutters 1 3a are installed on the front and left and right sides of the bottom of the elevator shaft frame 2; a laminated safety glass canopy 5 is provided directly above the elevator exit 11, and steel-concrete composite protective canopies 6 are provided on the front and left and right sides of the elevator shaft frame 2 at a height flush with the lower surface of the laminated safety glass canopy 5; a sliding observation window is installed on the inner side of the shutters 2 3b.

[0009] Preferably, the shutter 2 3b is a reversible shutter, and the sliding observation window is a sliding screen.

[0010] Preferably, the second shutter 3 b is installed above the anti-collision wall 4 or opened in the middle of the anti-collision wall 4 .

[0011] Preferably, the protruding length of the laminated safety glass canopy 5 relative to the outer wall of the elevator shaft frame 2 is greater than the protruding length of the steel-concrete composite protective canopy 6 relative to the outer wall of the elevator shaft frame 2 .

[0012] Preferably, the laminated safety glass canopy 5 is made of glass, and the steel-concrete composite protective canopy 6 is cast by reinforced concrete.

[0013] Preferably, an elevator door opening 7 is provided at a corresponding position of the existing building main body 10 on the side facing the elevator shaft frame 2 .

[0014] Preferably, anti-collision walls 4 are provided on both sides of the elevator door opening 7 at the lowest level.

[0015] Preferably, the top outer wall of the elevator shaft frame 2 is also provided with a steel-concrete composite protective canopy 6.

[0016] Compared with the prior art, the utility model has the following main advantages:

[0017] 1. The utility model is provided with upper and lower shutters at the corresponding positions of the upper and lower parts of the elevator shaft frame, respectively. The chimney effect is formed by the elevator shaft and the upper and lower shutters. Fresh cold air is sucked in through the lower shutters, and the hot air in the shaft is discharged through the upper shutters. It can effectively increase the convection ventilation in the elevator shaft, reduce the temperature in the shaft, and maintain a good equipment working environment;

[0018] 2. The utility model arranges a steel-concrete composite protective canopy on the outer ring of the elevator shaft in coordination with a laminated safety glass canopy just above the elevator exit, thereby facilitating shelter for residents entering and exiting the elevator while effectively preventing the outer protective wall (glass, plates, etc.) of the elevator shaft from cracking and falling and injuring people, and preventing rainwater from entering the blinds below.
