Device for finding reinforcement in concrete

Knowing where the hidden reinforcement bars are in concrete structures is essential when working with them. These reinforcing bars, also known as rebar, give the concrete the strength and stability it needs. But finding them precisely without the right tools can be difficult. This is where tools made expressly to locate reinforcement in concrete are useful.

Reinforcement locators, sometimes referred to as concrete scanners or rebar detectors, are indispensable instruments for anyone working on building projects, remodeling projects, or structural evaluations. These tools aid in determining the size, depth, and location of the reinforcement bars set into the concrete. They can find metal in the concrete without endangering the structure by employing electromagnetic signals or radar waves.

Employing a reinforcement locator offers various advantages. By stopping unintentional drilling or cutting into the reinforcing bar during building or renovation work, it protects the structural integrity of the building. It also aids in evaluating the reinforcement’s quality and positioning, both of which are essential for longevity and safety. Engineers and inspectors who have to confirm that the reinforcement complies with design specifications will also find these devices to be of great use.

The many kinds of reinforcement locators that are available, their functions, and their uses will all be covered in this article. Knowing these tools will make working with concrete structures safer and more effective, whether you’re a professional in the field or a do-it-yourself enthusiast.

Why do you need to look for reinforcement in concrete?

It is essential to know the location of reinforcement when performing technical maintenance, construction, and repair work on a building. A concrete reinforcement detector is used for these reasons. It establishes the diameter, the precise location of the reinforcement, and the concrete layer’s thickness. This is necessary because damage is done to more than just the equipment when a drilling or other tool strikes reinforcement. If the rod sustains minor damage, this could harm the reinforcement structure or cause the reinforced concrete panel to corrode later on.

GOST states that the magnetic method is used to measure the protective layer thickness and search for reinforcement in concrete structures. The method used to locate the threads in the metal rod crawl determines the thickness of the concrete layer. It is possible to use both ordinary strong magnets and hypersensitive devices, after all. However, only approved devices that are listed in the state register of measuring instruments are permitted to install these parameters in compliance with regulatory requirements.

This technique helps determine the location of the reinforcement and its approximate diameter, as well as the nuances of the protective layer and short-laying concrete during the structure’s construction. You can complete the task using this control method without compromising the structure’s integrity.

It scans the controlled plane in order to complete the task. Thus, all the required parameters are given out. The control sites open in order to make the indications regarding the rod diameters more clear. Method for installing reinforcement:

  1. scan the surface with a magnetic or geophysical method;
  2. determine the location of the reinforced mesh on the surface, the thickness of the protective layer and the location of the rods;
  3. open control areas and help determine the accuracy of these devices.

Finding reinforcement in concrete is essential to maintaining structural integrity when building or renovating. Builders can precisely locate embedded steel bars with tools like rebar scanners and metal detectors, avoiding unintentional damage and guaranteeing accurate drilling and cutting. These instruments lower expenses, save time, and improve safety by preventing needless structural repairs. The practice of locating reinforcement has become increasingly important for contemporary construction projects due to technological advancements that have improved its efficiency and dependability.

Search devices

These devices work on the basis of detecting changes in the electromagnetic field that occur when they collide with metal objects.

Elcometer P120

Among the quickest and lightest gadgets to use. It determines the thickness of the protective concrete layer, the direction, and the position of the rods. The device’s search head measures 10 cm in diameter. It uses both data on the scale and a loud sound signal to alert users to the search results. When working near large metal objects, data is not distorted.

The Elcometer P120’s sensitivity makes it possible to determine the direction of the reinforcement bars, both vertically and horizontally, with speed and accuracy. To find the maximum minimum signal level, the device must be moved in the direction of the rod after detecting the reinforcement. The fittings pass to the device handle at an angle of 900 when there is the minimum signal. Additionally, a headphone jack enables you to work in noisy and crowded environments.

  • detectable reinforcement diameter 0.8-3.2 cm;
  • measured concrete layer 1.2 – 1.6 cm.

Elcometer P100

This device is lightweight, dependable, and precisely determines the necessary parameters (reinforced rods, pipes, stainless steel ties, etc.) despite its low cost. Size of search head: 10 cm. gives you a loud beep when the scan is finished. The Elcometer P100 has a valve direction setting feature.

PROFOSCOPE

They perform operational monitoring of the concrete’s protective layer and the positioning of reinforcement bars using PROFOSCOPE. Measurement data can be saved with it, even automatically. It is preprogrammed with multiple storage modes, so you can select the most practical one to use and cut down on the time spent manually entering results. Because the sensor is integrated into the device body, its small size is guaranteed.

Because of the device’s portability and light weight, marking armopruts in parallel is feasible even when using one hand.

He uses audio and visual cues to inform people about the study’s findings. Its sensors are able to display rods’ diameter, direction, and position in real time, along with the thickness of the layer of protective concrete. Profoscope can pinpoint the precise location of the device—between or above some of the rods. As a result, a great deal less time and money are needed to complete the job, and the accuracy of the outcomes is maintained.

  • The determined diameter of the armraps is 0.5–5.7 cm;
  • measured concrete layer 0.5-18 cm;
  • operating temperature -100s -600C.

Search-2.51

In addition to maintaining data, the device automatically and manually determines the brand of steel and sets the concrete thickness and armrap diameter for two dimensions. With search-2.51 at their disposal Locate any areas devoid of reinforcement and use the appropriate techniques to evaluate the concrete structure’s strength there. It satisfies every GOST prerequisite. Three memory modes are available.

  • linear indicator, digital data and sound signal for searching for reinforcing bars;
  • accuracy in establishing the thickness of the concrete layer;
  • small size;
  • protective rods of the sensor easily slide along the tested plane;
  • built-in battery with charger.
  1. calibration in the device is performed automatically;
  2. graphic display with backlight;
  3. the ability to search for previously saved results by dates and numbers;
  4. 6 systems of use: searching for reinforcement at great depth; installing projections of reinforcement bars on the plane being tested; measuring the diameter of rods with a known protective layer of concrete; measuring the protective layer of concrete; measuring with unknown reinforcement parameters.

NOVOTEST Armaturoscope

There are three ways to use these devices:

  • The main one is the determination of the concrete layer in the known diameter of the armoprutes and vice versa;
  • scanning;
  • deep search.

The device scans the plane in an attempt to find reinforcement. This can be accomplished by rotating the sensor around an axis, which yields the concrete layer thickness. The linear indicator and display both show the distance to the reinforced rods. In addition, the gadget has a sound search function that allows one to discern the direction of the rods even in the absence of a display—the closer the fittings, the more often the sound signal occurs.

Using a dielectric spacer, NOVOTEST Armaturoscope measures the diameter of reinforcing bars. The gadget is made up of a block and a sensor that are connected by cables. Conventional rechargeable batteries power the system.
