It is convenient for fighting and evacuation, and a circular fire lane should be set up. With the accelerating pace of urbanization, urban land is increasingly tight, which promotes the construction of high-rise buildings. Many high-rise buildings, due to poor consideration of fire prevention design and other reasons, have many congenital hidden dangers, and fires occur from time to time, causing heavy losses. In order to create convenient conditions for fire fighting and rescue work and ensure the safety of buildings, circular fire lanes should be set up around high-rise buildings. However, regardless of the size of the building, it is indeed difficult to require the circular fire lanes. Lanes can be set up along the two long sides of the building. In order to prevent the collapse of building components in case of fire from affecting the normal operation of the fire lane, the distance between the fire lane and the outer wall should be 5m. There should be no trees, overhead pipelines, etc. that hinder the operation of climbing fire engines between fire lanes and high-rise buildings. If the total length of the building exceeds 220m, a fire lane shall be set up to pass through the building. There is no inner courtyard in the building, there are ring fire lanes around it, and fire engines crossing the building need to be set up. Q: An L-shaped high-rise building has a total length of about 170m, a length of 120m along the street, and a length of 50m along the inner street (residential road). Do you want to set up fire lanes crossing the building? A: The relevant provisions of the "Construction Regulations" and "High Regulations" consider that there is no restriction on the length of the two wings on the premise of meeting the requirements of fire fighting and evacuation. The building only needs to set up a pedestrian passageway connecting the street and the inner courtyard at the part over 80m along the street, and there is no need to set up a fire lane. In the planning of fire lanes, in addition to the relevant provisions of the "Construction Regulations" and "High Regulations", attention should also be paid to 永才之前曾在历史喜剧《哲仁王后》中饰演金皖，将透过《春情之乱》再次以古装和观众见面的他表示：金皖拥有调皮鬼般的莫名其妙魅力，陈金星则拥有完全相反的多才多艺、稳重的魅力。澎湖咽喉的重要性人尽皆知，只是海禁在先，如果在此设司，官民便可往来，虽然福建到澎湖没有多远，却也出了海禁的范围了，因此澎湖设防与太祖海禁之间，存在着根本性矛盾，朝廷在此设司，相当于自己抽自己嘴巴。金明将事情讲了一遍。李长明沉吟道：要真是板栗和小葱，那你是要去帮他们。寻找心中的彩虹，憧憬彩虹另一边的美丽世界。A few years later, the traffic era began. Station B has also started to implement the big member system. Well, how do you say it? It is only natural to support the original version. However, some plots or pictures of some cartoons are harmonious, and there are actually no very special pictures. Sometimes it is very serious viewing experience. As Bai Piao Wang, I naturally can't stand it. Because there are many things to operate on the PC side, there is not much feeling. Mobile terminals such as phablet feel particularly deep. One is advertisement. I can say a few words with my eyes closed. Is the holiday boring? Why don't you learn PS? , test whether you can become an excellent original painter! After all, websites do not use love to generate electricity, and there is nothing wrong with planting advertisements. However, in the era of big data, there are always some annoying things. For example, I accidentally opened a video with vulgar content, and then all kinds of similar videos were recommended crazily. I turned over several pages of this kind of video, which is really disgusting ~
