Light steel buildings require much less foundation than traditional steel mixtures!

Date:2019-03-06 Views:71

The requirement of foundation for light steel structure buildings is much lower than that of traditional steel mixtures.

For the foundation of the same structural unit, it is not appropriate to adopt natural foundation partly, artificial foundation partly, or two or more soil layers with different properties.

As the bearing layer, when the base plate or the end of the pile of a high-rise building with steel structure approaches or partially enters the inclined top of the underlying soil layer, it is advisable to deepen the foundation or increase the length of the pile, so that the bottom or end of the foundation are all in the same underlying room, so as to avoid possible uneven settlement.

The steel structure construction site can not avoid the additional edge of rivers, lakes and old rivers which may slip or ground crack when earthquake occurs. Targeted foundation stabilization measures should be taken and the restoring of foundation should be strengthened. When liquefiable soil layer exists in the bearing layer of foundation under High-rise Building Foundation in seismic area, measures should be taken to eliminate the adverse effects of liquefaction of soil layer on the superstructure. _Eliminate all the adverse effects of liquefaction settlement of foundation soil on steel structure buildings. One of the following measures can be selected according to local regulations:

1: Light steel buildings are reinforced by compaction methods, such as vibroflotation, sand pile compaction, dynamic compaction, etc. The lower interface of liquefaction depth of soil layer should be treated, and the measured value of standard penetration hammer number of treated soil layer should be greater than the critical value of liquefaction of soil layer.

2: When deep foundation is used in light steel buildings, the depth of stable soil below the depth of liquid man should not be less than 500 mm.

3: When using pile foundation in steel structure construction of light steel building, the length of pile tip extending into stable soil layer below liquefaction depth should be determined according to the bearing capacity of pile, and should not be less than the following values. All liquefiable soil layers within the bearing layer of high building foundation should be excavated.

Lightweight steel movable houses, which are widely known for their lightweight layout and light self-weight, have played an irreplaceable role in the construction of Temporary Dwellings in current cities, and have now completed the standardized form of temporary construction, and established the concept of efficient construction in everyone's mind.

The main advantage of building light steel movable house is that it is not affected by any geological environment. Whether wetland or dry area, it can carry out useful construction, and can save most of the construction time. Usually, the light steel movable house is mainly constructed by dry construction, and it is suitable for working in a variety of poor geological conditions. It also costs less in the aspect of earthquake resistance. As a result, light steel movable buildings often appear in areas with high earthquake incidence, and their devices and protection are relatively fast.

The construction of many concrete houses is necessary because the soil geology has the necessary grade. With the development of the times, people are gradually increasing the demand for houses, and developers are increasingly looking for efficient and high-speed construction of houses. Even if they find geological doubts in the land, they are forced to sell the above buildings. In doing so, they must bear the fruit of selling. The profit can not be paid, and in case of hurricanes or earthquakes, it will not be as aseismic and windproof as light steel movable buildings, and its safety factor is not as good as it.
