The fulcrum should be constructed as a fixed fulcrum

Before installation or disassembly, the competent department shall formulate a detailed operation plan in accordance with the requirements of the manual in accordance with the actual conditions of the construction site, and provide technical briefing and designation of guardians to all staff home escalator manufacturers before the work of the team. According to the regulations of the Ministry of Construction, the installation and dismantling staff shall be staffed by professional teams and those who have obtained the qualification certificates issued by the relevant municipal departments, and shall have special personnel to direct them.1. The horizontal displacement control value of the column top of the elevator shaft structure should not be greater than H / 500 (H is the height from the top of the foundation to the top of the column).

When arranged in an adhering manner, a steel structure should be used. The fulcrum should be constructed as a fixed fulcrum. 6. The structure of the elevator shaft should adopt the external attachment arrangement, and it can also adopt the independent arrangement and the internal attachment arrangement. 3. For an independently arranged elevator shaft structure, the wind vibration coefficient should be considered when calculating the wind load. When the elevator shaft structure is arranged independently, reinforced concrete structure can be adopted. 2

Therefore, in the design, we usually treat it as the front room of the fire elevator room, and do not protect the rest.’ Can fire hydrants located in the front room protect adjacent areas? The provisions of the ’High Regulations’ did not specify this, but the ’Fire Elevator Front Chamber shall be equipped with an indoor fire hydrant’ in the ’Building Design Fire Protection Code’ clearly states that the fire hydrant in the front of the fire elevator is for the convenience of firefighters The use of fire hydrants and the opening of channels cannot be included in the total number of fire hydrants..

At present, in some places such as Shanghai, fire protection design regulations require hat fire hydrants be installed in the front rooms of smoke-resistant stairwells in high-rise buildings.The ’High Regulations’ stipulates that ’fire hydrants must be provided in the front room of high-rise building fire elevator rooms
