How to make proper reinforcement of the foundation with your own hands: description, technology, instructions and feedback

Concrete has a sufficiently high compressive strength, but the base is not capable of transferring loads to tension and bending. If the foundation is provided, which is made in the form of a monolithic structure, with an armature frame, then the mentioned drawback will be completely eliminated. Reinforcement of the foundation with your own hands can be done quite simply. To begin with, it is necessary to decide on what structural features the base will have, and also correctly form the frame system.

Rules of reinforcement

The components of the reinforcing cage should have a clean surface, which will ensure good adhesion to concrete. In order to choose the type of binding of the reinforcement, it is necessary to calculate the load exerted on the foundation. If the effect on the base is negligible, then a wire type of knitting can be used. Whereas if the building has enough heavy walls, it is recommended to use welding.

Reinforcement of the foundation with their own hands should be done using rods that have a transverse variable cross-section, that is, they have ribs. This applies to the armature, which will take on the main load. Such a frame will be characterized by the highest levels of adhesion with concrete. Smooth reinforcement should be used as auxiliary elements, whose task will be to distribute loads to the base of the house.

Tool selection

Reinforcement of the foundation with your own hands should be carried out using a special tool. It should be selected based on the amount of work to be done. The binding of the reinforcing cage for a small basement should be done using a traditional manual or automatic hook, whereas if the work is more voluminous, it is recommended to use a specialized tool in the form of a pistol designed for binding.

Technology of work

For manipulations, use a piece of wire, the length of which is 30 cm. The workpiece should be folded in half. The wire loop should be brought along the diagonal of the fittings of the reinforcement, and after it is brought to the ends. The resulting loop is threaded into the hook, followed by a scrolling method. The master must interlock the ends of the wire, thus creating the desired connection. Before starting work, remember that the tape monolithic foundation during operation will be subject to bending stress, especially in the longitudinal direction. Its reinforcement should be made by laying a wire mesh in two or more layers. All this will depend on the size of the tape itself.

Armature for tape foundation

If the foundation is reinforced with your own hands, then you should take into account some points. Among them, one can single out the fact that in the belt structure the longitudinal elements of the frame system will assume the greatest load. In this regard, in their place should be placed ribbed rods, whose diameter is equal to a parameter of 10 to 14 millimeters.

As for the vertical and transverse elements of the frame, they will perform a distributive, that is, an auxiliary function. That's why in this case, you can use a smooth reinforcement with a diameter of 6 to 8 millimeters. The step of their installation will vary from 100 to 300 millimeters. The number of rods used depends on this indicator. With minimum loads, this figure can be equal to 500 millimeters. The finished frame should be mounted in a formwork, observing a gap of up to 50 millimeters. Retreat should be ensured from the bottom of the trench and formwork panels. This will drown metal rods in concrete, eliminating the risk of corrosion. It should be remembered that the highest level of stretching is in the upper areas of the base.

Recommendations for reinforcing the ribbon foundation

If reinforcement of the basement by oneself is done by oneself , it is recommended to pay attention to the joining technology of the reinforcement connection. Prepare a wire of class B1. When working with corners, the reinforcement can be laid at a right angle or using curved elements.

What you need to learn before starting work

If reinforcement of the strip foundation under the bath with its own hands is done, special attention should be paid to strengthening the corners. This is due to the fact that often enough deformation is not in the central part, but in the angular zones. Work on these areas should be in such a way that one end of the bent frame element goes in one direction, while the other end in the opposite direction.

Specialists advise to use the technology of knitting, rejecting the welding machine, for the reason that not every grade of reinforcement is suitable for carrying out such work. Among other things, welding often leads to problems that are expressed in the overheating of steel, which causes a change in the quality characteristics of the materials, and also the thinning of the rod in the welding area may occur. That's why you risk getting an insufficiently strong seam.

Methods of work

Correct reinforcement of the strip foundation begins with the installation of the formwork. The inner surface must be covered with parchment, which simplifies the removal of the structure. In the soil should be driven reinforcing bars, the length of which should be equivalent to the depth of the base. At the bottom you need to install a stand with a height of 80 to 100 millimeters. They fit about two or three threads of the lower row of the frame system. In the role of supports are often used bricks, which are installed on the edge.

If you reinforce the ribbon foundation, the schemes, tips for carrying out these manipulations, presented in the article, will help to carry out the work. The lower and upper rows should be attached together with the cross members to vertically oriented pins. In those places where the elements intersect, you should make a bunch or use the welding method. Above the ground level, the rods must be raised at least 8 cm. After the reinforcement has been installed, it is necessary to form the ventilation holes, and after pouring the concrete solution. Ventilation will contribute to increasing the depreciation qualities of the foundation, as well as prevent the appearance of putrefactive processes.

Strengthening plate foundation

The requirements for work on the monolithic plate are higher than those required for the tape base. In the latter case, the width is less than the height, which is why the structure experiences bending stress exclusively in the longitudinal direction. As for the monolithic slab, it has opposite structural features, due to this the surface experiences loads on the bend not only across, but also along.

If you are thinking about how to make reinforcement of the foundation with your own hands, then for this you should use a reinforcement diameter of 12 to 16 millimeters. All elements are made exclusively from ribbed rods. The average size of the cells at the top and bottom of the nets should be 200 x 200 millimeters. The step between the belts is equivalent to 100 millimeters. If there is a heating layer, then the assembly of the frame to strengthen the stiffeners should be carried out outside the base. This will prevent damage to the insulation material.

Strengthening the piling foundation

If you are interested in how the proper reinforcement of the ribbon foundation with your own hands is concerned, you may want to learn about strengthening the pile foundation. After all, it is this type of construction that can form the basis of the construction, which is supposed to be built. Technology in this case, almost nothing will differ from the work recommended for the formation of columnar foundation. In this case, it is necessary to observe one nuance. It consists in the fact that the vertical reinforcement is stacked in a circle in such a way that the system does not have angles and sharp areas. For one pile it will be necessary to prepare rods, the number of which varies from 3 to 5.

Methods of work

After the scheme of reinforcing the belt foundation with your own hands became known to you, you can get acquainted with the technology of strengthening the columnar foundation. The reinforcing cage should be assembled from several vertically oriented bars, the diameters of which vary from 10 to 12 cm. A ribbed reinforcement, which belongs to class AIII, should be used. To form horizontal elements, you should use a smooth thin mounting 6mm reinforcement.
