Is the hotel most suitable for the inner corridor or the span combination?

There are long corridors and short corridors in the inner corridor. Depending on the number of houses, one or two stairs (elevators) can be set in the middle or both ends of the inner corridor, and units can be set on both sides of the inner corridor to directly enter the household door from the long inner corridor. This kind of public transportation has a small area and a deeper building, which is conducive to saving land and energy, and the number of households served by one ladder is the largest.

However, this type leads to more households in one direction, and the residential buildings should be arranged in the east-west direction, which leads to greater interference between households; The short inner corridor is only provided with a ladder at one end. In order to overcome the shortcomings of the long corridor residence, reduce the number of households and shorten the length of the corridor, this type of residence was formed.

The advantages of the inner corridor residence are that the outer wall is complete, it is easy to make a regular and concise structural layout, and the seismic performance is good; Stair service households are more, and the land is relatively more economical; The construction cost is lower and the sales price is cheaper.
