How to distinguish between the inner balcony and the outer balcony

According to the Code for the Calculation of the Construction Area of Construction Projects issued by the Housing and Urban-Rural Development Commission in 2013, the inner balcony of the main structure and the outer balcony of the main structure are mainly judged to see whether the balcony is surrounded by load-bearing walls.

The balcony in the main structure can be understood as a concave balcony, and the balcony is in the load-bearing wall; The theme structure of the outer balcony you can understand as a convex balcony, the balcony is outside the load-bearing wall.

In layman's terms, if the wall of the balcony is made of the main wall on both sides, it is either a cantilevered board or a balcony in the theme institution. The convex balcony is cantilevered out of the slab. On the slab there is a little masonry wall.

The outer skin of the inner balcony is flush with the outer surface of the empty building of Jiantong, and the outer answer Lundan balcony is generally in the form of external picking, without cover - not counted, covered --- is counted as half, and the closed --- is all counted as clear disturbance.

According to the relevant regulations, the balcony refers to the space for users to carry out activities or dry clothes, and the floor area of the balcony is calculated according to 1 2 of the horizontal projection area of the period.

The residential building is located in an area where the building spacing standard is 1H and above, and the depth of the semi-open space shall generally not exceed the net height of the bottom of the floor beam; If it is located in other areas, the depth of the semi-open space shall generally not exceed the multiple of the net height of the bottom of the floor beam, and the semi-open space that meets the requirements shall be calculated according to the general construction area of the projection area, and the excess part shall be calculated according to the projection area; The projection area of the semi-open space in the residential suite shall not exceed 15% of the floor area of the suite. The construction area of the balcony in the suite is calculated according to the horizontal projection area between the periphery of the balcony and the outer wall of the house, the construction area of the closed balcony is calculated according to the horizontal projection, and the construction area of the unenclosed balcony is calculated according to the horizontal projection; The balcony (bottom balcony) is calculated as half of the horizontal projection area of its bottom plate; For the half-raised and semi-concave balcony, the construction area of the protruding part is calculated according to half of the horizontal projection area of its bottom plate, and the concave part is calculated as half of the construction area according to its combat area.

The calculation of the construction area of the balcony mainly depends on whether it is closed or not when it is originally planned, if it is not closed when it is planned, half of the area is counted, if the plan is closed, the closed wall is demolished or the whole area is counted. The calculation of the construction area of the inner balcony is generally calculated as the entire area, which varies according to the calculation method of each area and the developer.

Among them, the balcony space is divided into inner balconies and outer balconies. What is the difference between an inner balcony and an outer balcony?

The inner balcony is a semi-open space in the building structure, and the construction area of the inner balcony will be calculated according to the projected area;

Exterior balconies, i.e. semi-open spaces outside the building structure, are calculated in different ways depending on the situation.

How to calculate the floor area of the inner balcony?

The method of calculating the floor area of the inner balcony: area = length of the inner balcony * width of the inner balcony.

Balconies are easily classified into: concave balconies and convex balconies. The convex balcony is the balcony formed by protruding the exterior wall surface and picking the board; On the other hand, there is a balcony that is recessed into the interior of the exterior wall.

Or in terms of structure, it refers to the kind of balcony with load-bearing walls or columns on the outside of the balcony.

Terraces that are open-air or connected to the outside world are available. For example, if it is sealed with glass, it is part of the room.
