Reinforcement strip foundation with his own hands

Reinforcement strip foundation with his own hands

According to the rules and regulations of the foundations of everything, the concrete mass is necessary to strengthen the valve, but even the reinforcement strip foundation can be made with your own hands.

According to the laws of strength of materials, concrete monolithic block is capable of withstanding the highest loads in compression.

However, his strength at "bending" the load is quite small.

In fact, concrete is a brittle material.

To make concrete the necessary elasticity, strengthens its metal or composite reinforcement.This process is called reinforcement.

Reinforced concrete is able to perceive with the same reliability static and dynamic loads.

preliminary stage

procedure reinforcement strip foundation begins after a trench dug and equipped.Under

small bath-type facilities, a garage, a summer kitchen and a small house more convenient dig a trench by hand.

This decision has the following advantages:

  • small amount taken out of the earth;
  • flat wall trench;
  • volume of concrete required optimum.

At the bottom is filled with a layer of sand 10 cm thick, which is to be sealed.For these purposes, it sheds water.This is the most effective way to seal.

The video shows how the work is done by marking and preparation of trenches for pile-tape basis.

In order to properly calculate the need for reinforcement, it is necessary once again to measure the length and width of the trench.

If the pile-strip foundation is not rectangular, but more complex configuration, you need to take into account the size of the additional segments.

perimeter length, measured in meters, will serve as the basis for calculation in the fixture needs.

frame of the valve may have a complex profile.This depends on the size of the foundation.In the simplest embodiment, the frame is assembled from five longitudinal sections.

So, the perimeter length is multiplied by five.In this way, the total length of the valve is determined, which is required for the arrangement of the foundation.

frame assembly

should be considered when purchase of fixtures that require bars and cross bars for manufacturing.The standard length of rebar of 12 mm diameter is 11.7 meters.

Many years of practice shows that the frame can be made in advance and ready-made set in the trench.

often used another way, when the assembly of the reinforcing skeleton is performed with your hands directly into the trench.The principal difference between these two approaches do not.

Driving reinforcement

It is important that all actions carried out for assembling correctly, in accordance with applicable building codes.The specific choice is made based on the actual conditions.

monolithic pile-strip foundation got its name according to their strength characteristics.

This means that the strength of the base in any part of the same.

This condition greatly should provide reinforcement cage.Reinforcing constructions need to collect and record the assembled position so that its hardness was the same on every segment.

exceptions are the corners.Here, the connection is longitudinal and cross sections.They must be connected properly, in strict accordance with the requirements of technology.

Making cross members

frame designed for the reinforcement of pile-strip foundation, has a bulk form.

order to produce the required volume, it is possible to use shorter lengths of reinforcement, as well as special blanks circular or rectangular shape.

preferred to work with rectangular clamps that need to be manufactured in advance.This crucial stage, and all the operations needed to perform properly.

In forming the reinforcing core reinforcement is most often used with a diameter of 12 mm and 8 mm.Cross clamps bend of the wire rod.

reinforcing corners

In this case, the accuracy of performance required operations.So-called clamps must have the same dimensions.

Pre should make the layout of the rebar.The height and width of the body is determined in accordance with the cross-sectional dimensions of the tape base.

When the trench depth of 1 m and a width of 0.5 m, the size of the clamp should be 0.7 and 0.3 respectively.

These proportions are similar to the standards specified in the rules of construction.

Craft clamps can be their own hands.Here you can use the Benders, or make a simple adaptation of the materials at hand.

It is important to configure the device to work and sequence of operations.

Preparing reinforcement

next step is to prepare the valve, which will be collected from the wreck.Reinforcement rod must have the same length as the length of one side of the house.

In practice, such a coincidence is very rare.In the case where the valve rod is longer, it is cut to a desired size.

Video:

If the valve was shorter, it is necessary to build up.This is done in a simple bundle of two or more segments.The connection need to perform a special binding wire.

is important to remember that the bars overlap should be at least one meter.Reinforce foundation desirable whole segments of the bar.

frame assembly for the foundation

preferred to assemble the frame on the floor next to the trench under the pile-strip foundations.The first step should be to spread collars along the trench at a distance of one meter from each other.

next step - to pass a long section inside the valve mounting clip and perform at every point of contact.Then, in the same manner the following three sections are threaded.

they all bind to the binding wire clamps.Fifth segment reinforcement is laid over the resulting structure and is fastened to the collars in the same manner.

Proper installation fittings

Upon completion of this operation, we can say that the frame on one side of the foundation is ready.

In standard form pile-belt base such structures should be four.Two on the long side and two in width.

next step assembled structure fall into place in the trench.Here they need to bond with each other and make it right.

This is done in the same way with the use of binding wire.To enhance the design of exterior angles are connected by corner, from bent valves.

monolithic strip foundations require increased strength in the corner reference points.Tying rebar is performed using appropriate tools.

This can be a special pliers or a hook, which can be made with your own hands.

frame Installation

Once the frame is lowered into the trench, it is necessary to orient correctly.This is a responsible operation that determines the reliability of the base as a whole.

monolithic pile-strip foundation does not justify its purpose, if not met by the simple content requirements.

The first requirement is that the reinforcement bars do not protrude out of the concrete base.The video shows correctly installed in the trench reinforcement frame.

Experience shows that the rules are not always respected in the individual housing construction.Nothing good from this does not follow.

Tear off valves on the ground

According to many years of experience of building it is known that between the reinforcing core and the ground should be within a distance of ten centimeters.

In order to ensure this gap, using special supports.In practice, the fragments of brick is most often used or scrap metal corner.

horizontal layout

reinforced solid foundation is a long and reliable, if all the requirements for its arrangement performed with high precision.

upper frame plane should be set horizontally.In this case, the upper layer of the concrete will have a uniform thickness over the entire surface.

Vertical orientation

frame must be secured in the trench so that the valve is not in contact with the casing wall.

If this is not done, then the concrete is poured the entire structure can lose form and move to one side.

side struts can be easily installed by hand.For this purpose, the segments can be applied reinforcement.

Pouring the foundation

properly executed works on reinforcing strip foundation to achieve the desired result.The base will be long and reliably.

Even significant changes in external conditions, such as increasing the level of groundwater or soil subsidence will not have to tape the foundation of a significant impact.

At the same time it is important to accurately perform the final part of the work on the arrangement of the strip foundation as a whole.Pouring concrete is not difficult, but critical operation.

The video shows how it is done.

Video:

Many developers, who build a house with his own hands, prefer to perform the fill strip foundation alone.This decision is rational.

Pouring made in stages.In this case it is important that the valve position can be monitored and to prevent deformation or skewing.

Upon completion of the fill strip foundation must be cured within three to four weeks.
