What is the Foundation of the house? Is it a mandatory basis, the root, which bear the full load. This implies that it needs to be very strong and durable. Of all the modern types of Foundation strip is the most popular. In this article we will look at how needs to be carried out properly the scheme of reinforcement of strip Foundation with his own hands.
A little bit about the basis ↑
The belt kind of Foundation is a reinforced concrete structure closed type. It can be monolithic or team. Laid this Foundation for all main walls, and building mass is distributed over the entire square or rectangle (depending on what geometric shape is used in the construction of the Foundation).
Such basis is the easiest way to build your own. Complex types of fences that you install on heaving soils and other structures of various types are the easiest to put just on a continuous footing. Durability and reliability, the ability to withstand the serious load – it’s all about him.
It was said above that the Foundation is subjected to large loads. It is not only the weight of the building, but also the movement of soil, frost heave and other physical phenomena.
Erecting such a Foundation, we must remember that the reinforcement is laid illiterate, could lead to further destruction of the frame, which will undoubtedly lead to the deterioration of the whole building.
Base and fittings ↑
So, we go directly to the scheme of laying of strip Foundation with his own hands:
- the first stage involves the preparation of: the area cleared for construction, digging a trench along the border of the future building;
- next, set the formwork for the walls was proportional;
- with the formwork and reinforcement is carried out;
- then filled with concrete, organized waterproofing, and other work.
As can be seen from the diagram, the formwork and reinforcement are installed simultaneously. First erected formwork: the inner region of the trench is processed with parchment paper, allowing in the future to simplify the dismantling.
The frame is created according to the following scheme:
- reinforcing bars driven into bottom of trench. As mentioned above, must be observed the correct distance;
- on the bottom of the trench are set coasters size 80-100 mm, which is placed lower longitudinal row of valves;
- longitudinal rows of rods are fixed to the crosspieces hammered into the ground.
Why do you need reinforcement? This process is important to strengthen the whole structure, thanks to him, increased largely the lifetime of the building.
The choice of reinforcement products ↑
Buying rebar for such a framework, it is necessary to pay attention to the index products:
- «With» – will mean the sustainability of the products for welding;
- «To» – resistance to cracking from corrosion (the latter is possible at high loads).
In addition to the index, rebar can be divided and by category:
- A3 is suitable for longitudinal wrap. These rods represent the main load;
- A1 is already used for other ways of laying. The diameter of the rods preferably be chosen in the range of 6-8 mm.
Important points: proper reinforcement ↑
Note: to reinforce the middle part of the concrete Foundation is not necessary, as she really has no loads.
With regard to the standard canons of reinforcement:
- longitudinal bars must be placed inside the frame;
- connected to each other rods fittings – is a guarantee of the integrity of the concrete, non-proliferation of cracks and fixing of rods in the right position;
- the distance of the longitudinal rod and the transverse governed by building codes.
- determining the distance between the bars, it is necessary to take into account the diameter of the rebar, the location of the rods, the method of installation and much more;
- you cannot use welding in the reinforcing bars. From this distorted metal properties, quality decreases, but as mentioned above, if the valve selected by index «With», welding allowed;
- in any case we cannot allow the armature in contact with the ground or formwork. Otherwise, the metal rods threatened by corrosion;
- observed the distance of the outer surfaces of the future the base of the building;
- it is important to leave vent holes that enhance the cushioning characteristics of the Foundation, prevent corrosion process etc.
Special attention in the reinforcement must be given to the corners of the abutting strips of the base. Remember that the angle of concrete structures experiencing the greatest degree of load.
Need to know if the valve is in the corner of the strip Foundation will be installed incorrectly and the transmission from terminal to terminal will not be implemented at the appropriate level, solid base will lose strength. This is not a rigid, monolithic frame, and a set of individual beams, which can not be considered as a solid Foundation.
Example of proper reinforcement of Foundation under the fence ↑
Instruction:
- to start chosen valve cross section 8-10 mm;
- erected a frame, implying the connection of all rods in a single unit (connection: welding or tying).
Do note: the reinforcement strip Foundation under the fence involves the creation of such a framework, which would be two times smaller in width than in height.
The above tips for reinforcement of Foundation plate, diagrams and useful information to help make the construction of strip Foundation with his own hands. The most important thing – the basis of the future building will be reliable and durable, which allows for the construction of various monolithic structures.
