Foundation blocks - fbs and concrete block 400x200x200

In the construction of residential and industrial buildings often use prefab tape bases. Developers do not take into account the condition of the ground, which is not so important for them, and they can bear the design of any weight.

Main thought

Для этих целей выбирают фундаментные бетонные блоки PBS, устанавливают которые на подушку FL, что в итоге представляет собой мощную несущую конструкцию из железобетона. В данном материале о них будет рассказано подробнее.

Kinds

For each foundation w / w block, an appropriate marking is put, expressed in alphanumeric code.

With its help, it is possible to determine:

• the size;
• product weight;
• destination.

Imagine everything in the table:

Behind the letter symbols put the numbers designating the dimensions of the foundation blocks of concrete in decimeters, rounded to the nearest whole number:

• the first is the length;
• the second is the width;
• the third is the height.

The price of products mainly depends on their size. Also may affect the region of manufacture or plant concrete products. You can not ignore the dependence on the exchange rate.

Installation of precast strip foundations

It begins with a breakdown scheme, which includes:

1. Inventarju обноску;
2. Wire tension along the end wall axis;
3. The tension of the wire along the axis of the longitudinal wall;
4. Berth;
5. Creating a base axis.

Below is a process instruction:

1. Pull the metal wire you need to break the tape on the ram.
2. Install corner corner blocks
3. Depart from them 15 mm and install lighthouse blocks.
4. Draw a wire between beacons and corners, install intermediate blocks on it.
5. Align each element in the installation process vertically, for which use a leveling rail.

Tip: do not allow deviations in one direction or the other by more than 10 mm.

The zero cycle of the tape base is mounted in the same way as any other precast foundation, while you can use used concrete goods. However, this may be a problem associated with the intersection of the tape in the pit during the construction of industrial buildings. As a result, a crane boom may not be enough to mount intersecting nodes.

Tip: in this case, it is recommended to lay the blocks “away from you”, backing back. Then the arrow will be maximally involved in its length.

In private construction, everything is much simpler, since the size of the houses makes it possible for the crane to operate from only a few sections, and the boom will always be sufficient for the entire area. However, the overall breakdown plan should correspond to high-rise and heavy structures.

Сборный нулевой цикл в виде ленты можно изготавливать и не из PBS, а использовать для этого другие материалы, например:

• natural stone;
• brick;
• cellular concrete.

For example, foundation concrete blocks 200x200x400 will maintain light construction, in particular:

• bath;
• summer kitchen;
• garage;
• greenhouse;
• big house of wood.

Concrete blocks are also well established in the manufacture of column foundations, installed on unstable soils:

• пучинистых;
• swampy;
• man-made;
• peat.

In this case, they should be immersed below the freezing point and mounted on them a suspended grillage of reinforced concrete, metal or wood. Such devices are convenient to use in private construction, especially for the manufacture of wooden and frame buildings.

Успешно используются при создании нулевого цикла пескобетонные фундаментные блоки, хотя их лучше применять для изготовления бетонного цоколя, укладывая на монолитную ленту или PBS. При этом марка бетона для подобных полнотелых изделий бывает 100, 150 или 200.

Their advantage is a small weight, which will allow you to build masonry. It does not exceed 32 kg (the concrete block 400x400x200 has a mass of 50 kg), so special equipment is not required for installation in place.

Storage Recommendation

1. Проводите укладку PBS рядом со строительным котлованом высотой до 2,5м. Обычно это четыре ряда, но могут быть исключения.
2. The distance to the pit should be limited to the possibility of its collapse, which traditionally is no closer than 1 m.
3. When laying blocks along the roadway, the road should be at least 1 m.

Tip: when laying marking should be located on a vertical plane, which should be turned in the direction of the passage or passage between the piles.

To determine the value of the precast foundation, you need to know the total number of blocks:

• measure the total tape volume (lintels and perimeter);
• divide the resulting figure by the volume of the desired block;
• Multiply the result by the cost of one element.

Conclusion

In this article, the types of foundation blocks of reinforced concrete, concrete and their installation in the form of a tape base were considered. You also learned how else they can be used in construction and what their weight. The video in this article will help you find additional information on this topic.
