[0028] See also Figure 1-8 Describing this embodiment, the utility model provides an integrated structure of a boiler fire elevator vestibule and a boiler stairwell, which can be connected to a boiler room. The boiler room is provided with two boiler columns 6 spaced apart along a first direction. The integrated structure of the boiler fire elevator vestibule and the boiler stairwell includes an elevator shaft 1, an elevator vestibule 2, a stairwell 3 and an outer closed wall and stairwell columns 7. An elevator shaft steel structure is provided around the elevator shaft 1. The elevator vestibule 2 is arranged parallel to the elevator shaft 1 along a second direction, and the second direction is perpendicular to the first direction. The stairwell 3 is arranged parallel to the elevator shaft 1 along the first direction. A staircase 11 is provided in the stairwell 3. The outer closed wall and stairwell columns 7, the elevator shaft steel structure and the two boiler columns 6 are connected by steel beams to form an integrated frame structure. The elevator shaft 1, the elevator vestibule 2 and the stairwell 3 are all located within the integrated frame structure.

[0029] In this integrated structure of a fire-fighting elevator vestibule and boiler stairwell, the exterior enclosed wall and stairwell columns 7, the elevator shaft steel structure, and two boiler columns 6 are connected by steel beams to form an integrated frame structure. This integrated frame structure encloses the elevator shaft 1, elevator vestibule 2, and stairwell 3. By attaching the boiler steel columns, the stairwell 3, elevator vestibule 2, and elevator shaft 1 are integrated into a single structure, integrated with the boiler room. This improves structural stability and eliminates the need for horizontal bracing that would have been required for an independent structure extending through the boiler's enclosed exterior wall. This integrated structure integrates the stairwell 3 with the elevator shaft steel structure, enclosing it together with the boiler room steel structure. This increases structural stability and reliability, as well as the overall thermal insulation and sealing of the boiler room and its aesthetically pleasing exterior. This ensures the safety of life and property, personal safety, engineering safety, and ecological and environmental safety for construction and operational inspection personnel, achieving significant economic benefits. An independent elevator vestibule 2 is arranged between the elevator shaft 1 and the boiler steel structure, and a stairwell 3 leading directly to the furnace top is arranged on the same side as the elevator. The newly added space of the elevator vestibule 2 meets the fire protection requirements, and the stairwell 3 is convenient for staff to pass through and for daily inspection and maintenance of the boiler operation.

[0030] Optionally, a closed column 9 is provided between the two boiler columns 6, and a closed wind-resistant column 10 is provided between the boiler column 6 and the outer enclosed wall and stairwell column 7. It is understood that the closed column 9 is located between the two boiler columns 6, and the closed wind-resistant column 10 is located between the boiler column 6 and the outer enclosed wall and stairwell column 7. The closed columns 9, the closed wind-resistant column 10, the boiler columns 6, the outer enclosed wall and the stairwell column 7, and the elevator shaft steel structure are connected by steel beams to form an integrated frame structure, which can increase the stability of the structure and ensure the safety of staff passage. In this embodiment, there are two closed columns 9, and the two spaced closed columns 9 are both located between the two boiler columns 6.

[0031] Optionally, the elevator shaft steel structure includes four elevator columns 8 , which are respectively located at the four corners of the elevator shaft 1 .

[0032] like Figure 4 As shown, optionally, the integrated frame structure is further provided with a docking layer support structure at each elevator docking layer. This can increase the stability of the integrated frame structure. It is understandable that the docking layer support structure is formed by connecting the sides of the integrated frame structure with steel beams, and the docking layer support structure is in a horizontal state. Optionally, a horizontal support 12 is provided between the steel beams arranged in the docking layer support structure. The two ends of the horizontal support 12 are respectively connected to the diagonal lines of two adjacent steel beams of the docking layer support structure. This increases the stability of the docking layer support structure. It is understandable that there are multiple horizontal supports 12.

[0033] like Figure 5 and Figure 6 As shown, vertical supports 13 are optionally provided between the steel beams arranged on the sides of the integrated frame structure. The ends of the vertical supports 13 are aligned diagonally with two adjacent steel beams on the side, thereby increasing the stability and reliability of the integrated frame structure. It is understood that there may be multiple vertical supports 13.

[0034] Optionally, the integrated structure of the boiler fire elevator vestibule and boiler stairwell also includes a mechanical pressurized ventilation shaft 5, located in the elevator vestibule 2. This shaft 5 can be located inside or outside the elevator vestibule 2, depending on the actual equipment requirements.

This meets the latest fire protection regulations and can meet the needs of firefighters in the event of an accident, facilitating evacuation and ensuring personnel safety.

[0035] like Figure 1-3 As shown, the integrated structure of the boiler fire elevator vestibule and the boiler stairwell optionally further includes a fan room 4. The fan room 4 is arranged in parallel with the elevator vestibule 2 along a first direction and in parallel with the stairwell 3 along a second direction. The fan room 4 is used to supply air to the mechanical pressurized ventilation shaft 5. The vacant space of the integrated structure of the boiler fire elevator vestibule and the boiler stairwell is rationally utilized to arrange the fan room 4 equipped with a pressurized air supply system. The fan room 4 is provided with an air intake to facilitate the fan to draw air from the space outside the boiler room. Moreover, since it is relatively close to the elevator vestibule 2, the air supply distance of the air supply duct can be reduced.

[0036] Optionally, there are one or two fan rooms 4. If the building height is less than 100 meters, one fan room 4 is provided. If the building height exceeds 100 meters, two fan rooms 4 are provided.
