Corridor type residential building, what is corridor type building?

Townhouse. Detached house.

Unit. Point. Compound.

Corridor houses are divided into verandah houses and verandah houses, which are introduced separately below.

1. Corridor type houses in row low-rise houses, in multi-storey, high-rise panel houses and"y"type、"work"It is commonly used in point-type houses. This type of home is characterized by a common hallway on one side of the room, with the corridor end leading to stairs and elevators. Verandah dwellings can be divided into two types: long verandahs and short verandahs.

A ladder of a long corridor can serve many households on each floor, and a ladder of a short corridor can serve 2 or 5 households per floor. The verandah can be divided into two types: closed and open, the former is mostly used in multi-rise and high-rise residences, and is enclosed by columns, fences, and glass.

The advantages of verandah houses are: the division of households is clear, each or each house has an entrance and exit from the common corridor, each household can get a better orientation, and the lighting and ventilation are better.

The disadvantages of this type of housing are: the verandah is used as a public transportation walkway, which occupies a large area and the construction cost is high; At the same time, the doors of each household face the common corridor, which interferes with each other greatly. Most of these dwellings in our country were built in the 70s and early 80s, and very few are being built today.

2. The design of the inner corridor type building is used in multi-rise and high-rise residences, student dormitories of colleges and universities, collective dormitories of factories and hotels, hotels and hospitals.

It is characterized by a common corridor in the middle, and the dwellings are arranged on both sides of the corridor, and the households are arranged next to each other. Depending on the number of residents, one or more stairs (elevators) can be set up in the middle or both ends of the corridor, and the short corridor is only equipped with stairs at one end.

The disadvantages of the inner corridor type house are: the number of households serving the building (electricity) is more, each household has only one direction, and because the two rows of houses are side by side, the doors and windows cannot be opened to produce the hall wind, and the lighting and ventilation are much lower than the corridor type house; Due to the interior of the corridor, there is no natural light to illuminate, so it is too dark; At the same time, the corridor is shared between households, and the interference between households is twice as high as that of verandah-style houses. This type of home has a lower construction cost and is cheaper to sell**.

Corridor-type non-residential residential buildings include kindergartens, student dormitories, etc. So, what is a corridor-style non-residential residential building? What problems should be paid attention to in the design of corridor-type non-residential residential buildings?

What is a corridor-type non-residential residential building? Corridor type building, mainly refers to those, with corridor connection form as the main body of the plane layout structure, corridor is divided into inner corridor and outer corridor in the building, in the building plan, each room is mainly connected by corridor, can be considered that corridor is a composite structure, that is, corridor structure. The general corridor structures include hotels, schools, frame office buildings, etc.

The main thing to judge is still to see if it connects the rooms with corridors! According to Article 50016-2006 of the Code for Fire Protection Design of Buildings, the fire protection design of corridor-type non-residential residential buildings stipulates that when the construction area of any floor of the residential building unit is greater than 650m2, or the distance from the door to the safety exit of any household is greater than 15m, the safety exit on each floor of the building unit shall not be less than 2.

When the corridor type non-residential residential building exceeds the provisions of the table, there should be no less than 2 safety exits. The stairwell setting form of the residential building shall comply with the following provisions: 1. When the number of floors of the corridor residential building exceeds 2 floors, a closed stairwell shall be provided; When the door adopts a Class B fire door, a closed stairwell can not be set; 2 When the number of floors of other forms of residential buildings exceeds 6 floors or the construction area of any floor is greater than 500m2, closed stairwells should be set up, and closed stairwells may not be set up when the doors or doors and windows leading to the evacuation walkway and stairwells are Class B fireproof doors and windows.

Stairwells in residential buildings should lead to roofs, and doors or windows leading to flat roofs should open outward. When the elevator shaft in the residence is arranged adjacent to the evacuation staircase, a closed stairwell should be arranged, and a closed stairwell may not be set when the door adopts a Class B fire door. When the elevator leads directly to the garage at the lower part of the residential floor, the elevator waiting hall should be set up and fire separation measures should be adopted.

Corridor type houses are widely used in townhouse low-rise houses, multi-storey, high-rise panel houses and "Y" and "I" shaped point houses. This type of home is characterized by a common hallway on one side of the room, which leads to a staircase and elevator at one end. The advantages of verandah-style houses are:

Each household set of planes is directly combined and combined, and the horizontal long corridor directly enters the sub-household door, so that the sub-household is clear, and the public corridor of each building or each house has an entrance, and each household can obtain a better orientation, and the lighting and ventilation are better than the code. The disadvantages of this type of housing are: the verandah is used as a public traffic shed to open the walkway, which occupies a large area and has a higher construction cost; The doors of each house face the common corridor, which interferes with each other.

Corridor dwellings are classified according to the mold or orientation where the corridor is located, and there are two types: south corridor and north corridor. The south corridor is conducive to activities in the corridor, but the south-facing corridor interferes greatly with the living room, and the lighting and sunshine of the south-facing room are blocked in the north, and the application in cold and cold areas is limited by the difficulty of heat preservation and cold protection. The north corridor is easy to arrange auxiliary rooms or small rooms, which can reduce the interference to the main living room, and is generally used more.

It refers to a dwelling in which a shared staircase or elevator enters each house through the inner and outer verandahs.

Gallery tall building of apartment refers to a high-rise building that is accessed by a shared staircase and elevator through the inner and outer corridors. There are two types of corridor-type high-rise residences, which are now mostly used in the inner corridor type and less common in the outer corridor type.
