4. For the shops on both sides of the pedestrian street, the fire resistance limit of the envelope structure on the side facing the pedestrian street should not be lower than 1.00h, and solid walls should be adopted, with Class B fire doors and windows for doors and windows. When a fire-proof glass wall is used, its fire-proof integrity and fire-proof isolation should not be less than 1.00 h. When a non-thermal fire-proof glass wall with fire-proof integrity not less than1.00h is used, it should be automatically closed. A solid wall with a width of not less than 1.0m and a fire resistance limit of not less than 1.00h should be set between adjacent shops facing the pedestrian street.

pedestrian street
1. The end of the pedestrian street should not be closed on all floors. If it is really necessary to close, openable doors and windows should be set on the external wall (each floor should have openings or windows directly communicating with the outside world, and shops cannot be set up or closed in other ways), and the area of openable doors and windows should not be less than half of the external wall area of this position.
2. The length of the pedestrian street should not be greater than 300m (to prevent the fire from getting out of control, which will lead to the over-fire area, and the fire hose laid at the fire truck is too long to supply water when extinguishing the fire, which is not conducive to firefighters' access).
3. When the shops on both sides of the pedestrian street need to set up corridors or connecting overpasses on the upper floor (the width of the overpasses should be limited to a certain extent, generally controlled at about 4m, so it is impossible to change them into shops or add booths), the opening area of the upper floor of the pedestrian street should be guaranteed (first, the openings of each floor of the pedestrian street should be as large as possible, and no other facilities or floors should be set except the necessary corridors and connecting overpasses on both sides of the pedestrian street), and the opening should not be less than 37% of the ground area of the pedestrian street.
4. The distance from any point in the pedestrian street to the nearest outdoor safety place should not be greater than 60m, and the straight-line distance from the evacuation doors of shops on the second floor and above on both sides of the pedestrian street to the nearest evacuation stairs or other safety exits on this floor should not be greater than 37.5m (when determining this distance, it cannot be calculated by the straight-line partition of the shops).
5. The ceiling material of the pedestrian street should be incombustible or flame-retardant, the fire resistance limit of the load-bearing structure should not be lower than 1.00h, and combustible materials should not be arranged in the pedestrian street.
6. The height between the lower eaves of the ceiling of the pedestrian street and the ground should not be less than 6m, and the ceiling should be provided with natural smoke exhaust facilities that can be manually and automatically opened in case of fire (when the ceiling adopts natural smoke exhaust and the cloister area adopts mechanical smoke exhaust, the control sequence of smoke exhaust facilities should be reasonably designed).
7. DN65 fire hydrants are set outside the shops on both sides of the pedestrian street every 30m, and equipped with fire reels or fire hoses.
8. Each corridor should be equipped with automatic sprinkler system, and the pedestrian street should be equipped with automatic tracking and positioning sprinkler system.
9. Pedestrian street should be equipped with fire emergency lighting evacuation signs and fire emergency broadcasting system.

For me, the fire test is really beyond my control, so I signed up for a class and reviewed with professional teachers. I saw the memories of Qianfeng on the Internet, overheard Mr. Bai's class, and then I was attracted. I think the way she lectured quickly made me remember some knowledge points. She brought the knowledge points into the scene by making up stories, and she would remember the knowledge points as long as she listened to the story once. You can look at their curriculum advantages.
The following is for students who need to sign up for classes. If you want to sign up for class as soon as possible, you can learn more memory methods earlier. When you sign up for classes, listen to their free open classes online first to see if the methods they talk about are suitable for you. There is a free open class for striker memory, so you can listen to it first. I think it's really good.
