What are the foundations of light steel structure villas? -wellcamp light steel villa manufacturers
The foundation types of light steel houses are: strip foundation, slab foundation, and independent foundation; light steel villas mainly use strip foundations. 1. The advantages of the strip foundation: good seismic performance can improve the integrity of the foundation, and the mechanical performance is good, which is conducive to earthquake resistance. 2 Cost saving: Light steel villas are light in weight, only about one-fifth of that of brick-concrete structure houses, which can greatly reduce the cost of basic construction (compared to traditional houses, the required manpower and materials can be greatly reduced). 3Convenient sampling Red bricks, concrete, building steel bars, sand and gravel used in independent foundations are all widely used in engineering construction, with low price and convenient sampling. The basic specifications of the independent foundation in the lightly steel structure villa: the effect of the ground ring beam: the independent foundation can transmit the load of the wall or column to the roadbed, so that it can consider the requirements of bearing capacity and deformation, improve the comprehensiveness of the house and the bending stiffness of the interior space, Avoid the bad damage to the house due to uneven subgrade settlement or large vibration load. The ground ring beam at the position of the basic wall top and the overhang position is more reasonable in resisting the asymmetrical foundation settlement. Foundation pit and construction line-out; the process is roughly divided into: 1. Precise positioning of engineering buildings and accurate positioning of basic measurement and line-out, using RTK to set less than 4 precise positioning piles on the construction site. 2. Release the precise positioning piles of the center line of the building, and integrate the clear precise positioning piles and the plane design drawings to carry out specific construction layout. Foundation pit: The depth of the deep foundation pit is a more important factor. The geology of the soil layer of the housing base and the floor height of the self-built house in rural areas are directly affected by the depth of the deep foundation pit. Under normal circumstances, it is necessary to excavate the earthwork and backfill the mattress layer before considering the structural load bearing capacity. Generally, the depth of the deep foundation pit is not less than 60CM. Concrete pouring and maintenance of the foundation cushion: the foundation cushion is the inner layer of the concrete structure and the subgrade soil. The earthwork backfill of the foundation trench should be repaired and marked before, and concrete pouring should not be continued in the same place. Concrete pouring and maintenance: After pouring, cover with straw or sacks to prevent dry cracking and freezing. If the weather is too hot, pay attention to the change of cement color (if it has turned white, spray it and pour it wet). If the weather is too hot after 2 days, 3 times in the morning, noon and evening (as early as around 6 o'clock, at 10-11 o'clock in the middle, and at 6-8 o'clock in the evening), and 2 times if it is not hot. Mainly to check the change of cement color; dry fast watering times increase.
