How to make proper reinforcement of the foundation with your own hands: description, technology, instructions and feedback
Concrete has a high enough strength forcompression, but the base is not capable of withstanding the stresses on stretching and bending. If you supply a foundation, which is made in the form of a monolithic structure, with reinforcing cage, then the mentioned deficiency will be completely eliminated. Reinforcement of the foundation with your own hands can be done quite simply. To begin with, it is necessary to determine what constructive features the base will have, and also correctly form the frame system.
Rules of reinforcement
The components of the reinforcing cage must haveclean 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 impact on the base is insignificant, 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 your own hands shouldmade 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 shouldcarried out using a special tool. It should be selected based on the amount of work to be done. The viscous reinforcing cage for a small basement should be made 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 manipulation, use a piecewire, the length of which is 30 cm. The workpiece should be folded in half. The wire loop must be brought diagonally across the crosspiece of the armature, and after it is brought to the ends. The resulting loop is threaded into the hook, followed at the same time by the 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 subjected 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.
Fittings for strip foundation
If reinforcement of the foundation is to be madewith your own hands, you should consider 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 vertical and transverse elementsskeleton, 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 index. 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 beltfoundation with their own hands, it is recommended to pay attention to the joining technology of joining the reinforcement. 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 beltfoundation under the bath with their own hands, then 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 curved frame element goes in one direction, while the other end in the opposite direction.
Experts recommend usingtechnology knitting, abandoning 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 steel overheating, which causes a change in the quality characteristics of the materials, and also the thinning of the rod in the welding area can occur. That's why you risk getting an insufficiently strong seam.
Methods of work
Correct reinforcement of the ribbon foundationbegins 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 will be reinforcedribbon foundation, 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 carry out a bunch or use a 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 occurrence of putrefactive processes.
Strengthening plate foundation
Requirements for work on monolithica plate higher in comparison with those which are shown to 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 reinforcementfoundation with your own hands, then for this you should use reinforcement with a 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 theCorrect reinforcement of the ribbon foundation with your own hands, then you may want to learn about strengthening the pile foundation. After all, this type of construction 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 the columnar foundation. In this case, it is necessary to observe one nuance. It consists in 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 bars, the number of which varies from 3 to 5.
Methods of work
After the tape reinforcement schemethe foundation has become known to you, you can also 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.
