Project stage

The type of reinforcement used has an impact on the structure’s operational resource and is chosen during the design phase. There are a few things that need to be done in advance of making a strip foundation’s reinforcement frame material purchases. Complete execution of the preparatory work ensures that the future building will last.

Strengthening the strip foundation

The following tasks are involved in the design stage:

• Study, analysis of soil characteristics, mass of the building being erected. Evaluation of these parameters allows you to calculate the forces, select the required reinforcement. The diameter of the rods is from 10 mm for light structures to 14-17 mm for heavy structures erected on weak soils.
• Determination of the type of future foundation. The range of rods used depends on the selected type of foundation. Different sizes of rods are used for columnar, strip and monolithic foundations.
• Calculation of the need for reinforcement rods, taking into account the dimensions of the building being erected, foundation features, and soil type. Knowing the required amount, it is easy to calculate the need for financial resources.

Although the reinforcement skeleton serves the same purpose for all reinforced concrete bases, the designs of these frames vary depending on the kind of foundation.

Making sure your foundation has a reinforcing frame is essential to guaranteeing the robustness and longevity of your building project. This post will guide you through the entire process of building a reinforcement cage on your own, from choosing the appropriate materials to putting the frame together. This guide will help you lay a lasting foundation and simplify any task, whether you’re a DIY enthusiast or taking on a small project.

Design features

Steel rods with unique ribs are used to produce reinforcement cages, which increase the rod’s coefficient of adhesion to concrete. When subjected to forces and temperature fluctuations, the integrity of a reinforced concrete massif cannot be achieved by using smooth rods.

The following variables affect reinforcement cage strength:

• brand of the metal rods used;
• section of the rods used;
• correctly developed design scheme regulating the quantity, assortment of reinforcement;
• selected method of fixing the reinforcement.

The most challenging reinforced concrete foundations are strip reinforced ones; while the basic structure is the same, the number of adjustments and labor intensity involved in creating the frame are more complex.

Reinforcement is used to create the foundation frame; its diameter should not be less than 12 mm. For reinforcements meant for utility buildings, tiny summer cottages, garages, buildings composed of gas-filled composites, or foam blocks, a smaller assortment may be used.

Class A-2 or A-3 rods, whose strength characteristics can guarantee the stability and durability of the foundation and, consequently, the building being erected, are used to strengthen the foundations of private buildings.

Types of reinforcement fastening

The following techniques are used to join separate metal rods into a single structure to form reinforcement frames:

• Connecting rods using electric welding.
• Fixing reinforcement using knitting wire.

Using wire for knitting and carrying out tasks with a specialized tool is a tried-and-true technique for fastening reinforcement rods for a strip foundation.

Electric welding has several drawbacks when it comes to damaging the metal’s structure and reducing its strength properties when used to fasten rods.

Frame welding is still not widely used. Let’s focus on the advantages of utilizing knitting wire to secure rods.

Specifics of knitting

The following techniques are used to produce reinforcement cages with elements fixed with knitting wire:

• manual binding of reinforcement, characterized by increased labor intensity, requiring the application of significant efforts, high time costs. Fixation of rods is carried out at the joints using annealed wire with a diameter of 0.8-1.2 mm. With the manual method, pliers or a special hook are used to perform knitting, the use of which allows you to firmly twist the ends of the wire, ensuring the fixation of the rods;

A unique wire is used to connect the reinforcement rods to one another.

• automated method, involving the use of a special gun for knitting. The device guarantees high-quality connection of rods, fast execution of operations. The time required to fix a pair of rods does not exceed one second. The gun is used when performing significant volumes of work.

Durability of the constructed foundation is guaranteed by knitting wire-fastened reinforcement cages, which are strong structures.

Types of reinforced structures

The various metal rod-based spatial structures serve the functional purpose of guaranteeing the strength of the reinforced concrete monolith. A particular type of foundation’s reinforcement cage has unique design elements that include:

• The presence of two reinforcement contour belts, fastened with transversely located rods. It is used for a solid strip-type foundation.
• Use of a rod mesh, providing rigidity of slab foundations.
• Use of vertically located rods, fastened with solid transverse contours, guaranteeing the strength of bored pile foundations.

Two reinforcement meshes make up the slab foundation frame, and the spacing between them depends on the slab’s chosen thickness.

Types of reinforced foundations

Let’s look at the different kinds of reinforced concrete foundations that use steel rods for reinforcement:

• strip foundations are common in private construction, as well as in the industrial sector. Reinforcement frame for a strip foundation is a complex and responsible structure, the elements of which are fixed with knitting wire or clamps made of plastic. The spatial structure absorbs tensile and compressive forces, ensuring the integrity of the foundation. The manufacture of reinforcement frames for strip foundations is carried out directly both in the assembled formwork and separately, with subsequent lowering of finished elements into the trench;
• slab foundations are relevant when constructing buildings on problematic soils. The thickness of the slab regulates the strict interval between two rod grids representing reinforcement frames. The metal rods of the meshes are located inside the concrete massif, reliably protected from corrosion. The thickness of the protective layer is 5 centimeters. The nets are made of transverse and longitudinal rods, the cross-section of which is 12-14 mm;
• a bored-type pile foundation allows the facility to be put into operation immediately after construction, but is characterized by a long cycle of preparatory activities. The reinforced frame has a simple design compared to other types of foundation reinforcement. The reinforcement frame contains longitudinally placed steel rods. The length exceeds the dimension of the bored pile by 0.3-0.5 m. Structurally, the frame consists of a group of 4-6 rods with a diameter of 12 mm. They are tied with transverse clamps, the shape of which resembles a triangle or circle.

Reinforcement cages are used in the construction of these kinds of foundations.

Sequence of operations

While working independently to form the strip foundation’s reinforcement contour, adhere to the following operating recommendations:

• Prepare rods of the required length and diameter, corresponding to the previously developed sketch.
• Cut the rods, observing the required dimensions.
• Lay smooth transverse rods (6-8 mm cross-section) of the required size at the calculated interval, ensuring a distance of 5 centimeters to the edges of the tape.
• Place two ribbed rods with a diameter of 12-16 millimeters on top, forming the lower contour.
• Install vertical reinforcement at the points of rod junctions, ensuring its length is 10 centimeters below the total height of the future foundation.
• Ensure a distance of 5 cm from the reinforcement contour to the ground, using pieces of brick, waste, special supports.
• Fix the elements using knitting wire and a special device.
• Assemble and fix the rods of the upper tier in a similar manner.
• Check the reliability of the wire fastening, the immobility of the spatial structure.

When assembling, use a special tool to pre-bend the protruding ends of each tier’s rods, which will provide the required overlap and rigidity to the corner zones and enable you to form a sturdy spatial reinforcement frame.

To guarantee the stability and longevity of your structure, you must build a reinforcing frame for your foundation. A sturdy foundation that will support your building for many years can be created by following the right procedures and utilizing the right materials. Don’t forget to precisely measure, cut, and tie your rebar before positioning it inside the formwork.

Even though it might seem like a difficult task, a do-it-yourself enthusiast can successfully construct a reinforcing frame with careful planning and attention to detail. Take your time to comprehend the configuration and style of your foundation, and don’t be afraid to ask for help or refer to building regulations and guidelines. Taking a hands-on approach not only reduces expenses but also helps you gain a better understanding of the fundamentals of your project.

In the end, the caliber of your labor and the supplies you utilize will determine how well your foundation works. Make safety and accuracy your top priorities at all times, and you’ll lay the groundwork for
