If you want to build a two story building, how deep is the foundation most appropriate? How deep the

How deep should the foundation of the first and second floors be?

1. Building a two-story house is very common nowadays, I believe we all know that the foundation is the foundation of the house when building a house, the foundation of the two-story building is about 70 centimeters deep, and the width is about 50 centimeters to ensure the stability of the house, of course, the soil medium of the foundation is also a factor affecting the depth of the foundation.

2. If the soil medium is relatively soft, the depth of the two-story foundation can reach one and a half meters to support the weight of the house, so that the built house is relatively safe and stable. If the depth of the foundation is not enough, then the built house will have cracks, deformation, and even collapse after a period of time.

2. What are the requirements for building a house foundation?

1. Settlement requirements.

If the settlement exceeds the scope of the standard, then the stability of the house will deteriorate, and over time there will be tilting and cracking of the house. Therefore, the foundation of the building house should meet the requirements of settlement, so that the built house will be more stable.

2. Strength requirements.

The so-called strength requirements refer to the bearing problem of the foundation, the foundation has a certain bearing capacity, in order to be more stable and firm in the house, if the quality of the house does not meet this requirement, there will be serious mistakes, whether it is to build a house or buy a house, we should pay attention to whether the foundation strength is enough.

3. Seismic requirements.

For areas prone to geological disasters, the foundation of the house should also meet the requirements of earthquake resistance, and the depth of the foundation should not be less than one-fifteenth of the height of the house according to the seismic requirements. However, in actual construction, it is also necessary to consider the specific depth according to the soil medium.

You can use 2 12 above and 2 14 below, and 10 rebar ,.. for stirrups and 20 cm spacing floor slabs of 6The soil quality of the foundation of the self-built two-story house is better, generally about a meter, room.

The foundation depth of a two-story building is generally 1.5 meters.

If the foundation is very wide, it can also be buried shallower, but the depth should not be less than the outdoor ground, so as to play a protective role. The actual height should not be less than 1 15 of the height of the house on the ground, and the pile foundation should not be less than 1 18, and the pile length should not be calculated.

The depth and length of the foundation are determined by factors such as the height of the actual house, the structure of the house, the quality of the soil and the climate. If the house has a high number of floors and deep rock formations, the foundation must be laid very deep. If the house is low and the rock formation is shallow, the foundation can be relatively shallow.

Precautions for laying the foundation:In order to make the building safe and normal use without being damaged, the foundation is required to be not damaged under the load. The deformation of the soil layer that makes up the foundation due to expansion and contraction, compression, frost heave, collapsibility and other reasons should not be too large.

Therefore, when carrying out foundation design, it is necessary to consider:

1. The pressure per unit area of the bottom surface of the foundation is less than the allowable bearing capacity of the foundation.

2. The settlement value of the building is less than the allowable deformation value.

3. There is no danger of sliding the foundation.

Summary. Generally, the foundation depth of high-rise buildings is about 20 meters to 30 meters, high-rise buildings refer to residential buildings with a height of more than 27 meters and non-single-storey factories, warehouses and other civil buildings with a building height of more than 24 meters, and high-rise and super high-rise buildings within 150 meters are generally buried in the ground at a depth of about one-eighteenth to one-twelfth of the height above ground.

How deep is the foundation of a typical high-rise building?

Generally, the foundation depth of high-rise buildings is about 20 meters to 30 meters, high-rise buildings refer to residential buildings with a height of more than 27 meters and non-single-storey factories, warehouses and other civil buildings with a building height of more than 24 meters, and high-rise and super high-rise buildings within 150 meters are generally buried in the ground at a depth of about one-eighteenth to one-twelfth of the height above ground.

The main points of the structural design of high-rise buildings are: 1. Consider the horizontal lateral force generated when the high-rise building encounters huge wind and force; 2. Strictly control the height-width ratio of high-rise buildings to ensure their stability; 3. Keep the quality and stiffness of the building plane, body shape and façade symmetrical and symmetrical as much as possible, so that the overall structure does not have weak links; 4. Properly deal with the deformation node structure caused by wind, temperature changes and foundation settlement; 5. Consider how to ensure safe and reliable design technology and construction conditions under the geological conditions of large weight and deep foundation.

Dear, hello, your question has been received, the answers to the relevant questions are as follows: to build a two-story small building foundation to refer to the following: Generally, the foundation of the two-story building should not exceed three meters, otherwise it will be easy to cause the foundation to sink in the later stage, if the foundation of the self-built house with two floors alone should be about one meter and twenty as well, because the depth of foundation embedding is related to the stability of the building, and it is also to let the indoor drainage pipe lead to the outside of the construction, and will not collide with the ground beam. If there is a shallow layer of mud, then you must dig down to remove the mud layer, if the soil quality is better, it is a clay layer, then you can dig about a meter.

50 cm wide and 70 cm deep.

The foundation is mainly the importance of supporting the superstructure, and the importance of the medium of the soil layer of the foundation is not the same for different depths. The function of the foundation is to maintain the relative stability of the house and the ground, and the weight of the foundation is much larger than the sum of the total objects in the house and the house.

With such a foundation, we can consider other issues such as the re-elevation of the house and the renovation of the house, so that the house is safer to live in. If the house is built without a foundation, over time, there will be cracks, deformation, and even collapse of the house.

Summary. Hello, a four-storey house from a self-built house requires a foundation depth of two meters. Because the depth of the general four-story foundation is about to be meters, in fact, this is also to be judged according to other factors, the depth of the foundation of the building and the building itself is the load, the base area, the site endurance, the depth of the local frozen soil, the height of the building, the shape of the building, the history can be said to be the largest wind and snow lotus, the fortification intensity, groundwater level, foundation treatment methods and so on are very related.

The foundation can be dug to the old soil, which is generally about 1 meter.

The beam depends on how big the beam is, generally 24 * 24 or something, you can use 2 12 above and 2 14 below, and the stirrups are 6 with a 20 cm spacing.

For the floor slab, 10 rebar is used, and the upper and lower skins are spaced 20 cm apart.

C25 is used for concrete, and C25 is generally used for small public housing, of course, C20 is also available, but I think C25 is more reliable.

The house built in this way is said to be able to barely resist Wenchuan** and not be destroyed.

If the frame structure is made, the frame column size: 200*350 400mm or 240*300 350mm.

If the brick-concrete structure is made, the size of the structural column: 200*200 250mm or 240*240mm.

The depth of foundation embedding should be determined according to the characteristic value of the load-bearing capacity of the foundation soil layer, and the conditions such as the perennial permafrost depth in the area should be considered. Self-built two-storey house foundation soil quality is better, generally about meters, indoor, outdoor floor at least 300, 1500-300 = 1200, foundation and cushion with 500 and 700 left, considering the outer diameter of frozen soil or sewage pipe, the outdoor covering soil is less than 600. That's basically the number.

Further information: Foundation refers to the soil or rock mass that supports the foundation under the building. The soil layer that serves as the foundation of a building is divided into rock, gravel soil, sand, silt, clayey soil and artificial fill.

There are two types of foundations: natural foundations and artificial foundations (composite foundations). A natural foundation is a natural layer of soil that does not need to be reinforced by man. Artificial foundations need to be reinforced, and there are stone chip cushions, sand cushions, mixed ash backfill and then tamping, etc.

Foundation requirements: strength, the foundation should have sufficient bearing capacity;

Deformation, the settlement of the foundation needs to be controlled within a certain range, and secondly, the settlement difference of the foundation in different parts should not be too large, otherwise the upper part of the building will crack and deform;

Stability, the foundation must have the ability to prevent overturning and instability.

Pressure, proper pressure.
