Precast Shuttering Magnet

Working Principle of Shuttering Magnet:

The precast concrete industry has been searching for a more economical and efficient formwork method. In the past, some conventional magnets were used to position and fasten the formwork, but considerable mechanical loads with a hammer were required, which was easy to damage the magnets and the surface of the expensive formwork tables as well. Excellent design of magnetic circuit could generate strong magnetic force obviously with less permanent magnets and then lower cost. For the shuttering magnets, the core component is the magnetic array. The block shaped Neodymium magnets and low carbon steel plates form a special magnetic circuit so as to supply an extremely high holding force when it attaches to a steel table. Moreover, the holding force may vary much when the air gap changes.

Structure of Shuttering Magnet:

Our precast concrete shuttering magnet provides quick operation leading to improved efficiency when setting out and breaking down the formwork. The structure is simple, composed of a Neodymium magnet array, steel shell, switchable button and two integrated screws through the top side of the steel shell. Due to NdFeB magnet’s strongest permanent magnet material currently and developed magnetic circuit designed, the siderail magnet system may generate enough force needed especially in the vibration, compacting and tilting processes of concrete to fix formwork tightly, but with light weight and small size. By pressing the button on top of the steel shell, this magnetic force is activated so that this shuttering magnet can fasten the formwork to the steel table tightly. (That’s why the formwork magnet is called on/off button magnet.) In a deactivated mode, the shuttering magnet is easy to position. By means of two threaded holes integrated on the top, this siderail magnet can be equipped with various adapters, which can provide unlimited options for use.

Features of Shuttering Magnet:

1. Universal: This feature is one of the most important factors for precast concrete plants to consider for their production. Universal for production of most PC elements, such as window, stairs, floor slab, solid slab, solid wall, double wall, sandwich wall, beam, column, etc; universal for almost all formwork materials, such as steel, wood or aluminum; universal for fixing most directions, height and shapes of shuttering, with the help of two integrated screws and adapters; universal for most production systems, such us stationary production, pallet circulation production, etc; universal for most retaining force and limited space required, with several options of holding force from 450kg to 3100kg and customized design.

2. Safe: Except the retaining force side, the other five sides are covered by the U shape steel housing, which reduces the danger risk of strong magnetic force to operators.

3. Reusable: Not only once application, but reusable use to reduce invest cost. The steel shell protects the inside magnet array against rust or damage and then extend its service time.

4. Easy: The switchable button makes it easy to turn on or turn off the strong retaining force. Company size and light weight is easy to operate with exact position.

5. Efficient: Avoid welding or bolting to the expensive formwork table, therefore, preserving the surface finish. It increases productivity and quality of precast concrete production.

Who Worth Us Competing with in the World:

In the world dozens of companies produce or market the shuttering magnet or magnetic shuttering. However, we only regard Ratec, Weckenmann and Elematic as our competitors, because all our shuttering magnets have the similar strength in the aspect of quality, long service time, design capacity, and professional in magnetic shuttering field. Ratec is an innovation leader in magnetic formwork technology including shuttering magnets (siderail magnets) and magnetic shuttering systems for precast concrete production. In addition, it offers a steadily growing portfolio of room cell formwork for numerous applications. Weckenmann is a leading manufacturer and developer of plant systems for the manufacturing of two dimensional and structural precast concrete elements that are used in residential and industrial construction. Its plant system is a wide portfolio of products like machinery, formwork, control solutions, and formwork profiles supported by the shuttering magnet or its said MagnetBox. Elematic is the global technology and market leader in precast concrete production technology for residential and non-residential buildings. Its FaMe magnet shuttering system is composed of unique shape of shuttering magnet or its FaMe magnet.

What Precast Concrete Elements Production Requires Shuttering Magnet:

Our shuttering magnet offers a wide variety of casing material, shape, size and holding force. Therefore, it is suitable for preparing precast concrete molds for almost all types of precast concrete elements, especially like walls, columns, beams, including window and door openings, recesses, etc.

How to Use Shuttering Magnet along with Adapters and Releasing Tool:

Shuttering magnet makes it easy to put the side forms to desired places and attach them to the mold. Before pushing the button on the top of the steel casing, you may easily move the shuttering magnets by sliding them on the surface to the exact positions. Then, press the button to activate the magnetic force and then the shuttering magnet can fasten the formwork to the steel table tightly. Sometimes, operators might choose to equip various adapters with two threaded holes integrated on the top, which can provide unlimited options for use. If you want to remove the formwork, you may attach a releasing tool or lifting lever to the button and then push the handle to turn off the magnetic force easily. The shuttering magnet is light and convenient to move and position during operation.

Typical Projects that our Shuttering Magnets Support:

In the world Hundreds of customers keep using our shuttering magnets in their precast concrete production, and the typical project is Manila LRT1 Cavite Extension Project. Manila LRT 1 is a fully elevated north-south route. It runs on a precast concrete structure 7 m above the street, designed to withstand earthquakes. LRMC work with Bouygues Travaux Publics as the engineering, procurement, and construction contractor for this LRT-1 extension. Bouygues Travaux Publics is an expert in large-scale projects involving tunnels, engineering structures, as well as road, port & rail infrastructures. Our HM-MF-0900 shuttering magnets and steel magnetic chamfers were selected and supplied to support this project.

Special Precautions in Using Shuttering Magnet:

1. Uneven surface of working side may generate air gap between siderail shuttering magnet and the formwork table, and then reduce the retaining force. Please regularly check the NdFeB magnet array and keep it clean and free from any big foreign substances.

2. The working side has strong retaining force. Please keep it far from electronic instruments and unnecessary ferromagnetic metals. The operator is highly recommended to wear gloves, and work with care so as to avoid any parts of his body clamped by the working side to any other ferromagnetic metals. Special caution should be exercised if someone is wearing a pacemaker, because strong magnetic fields can damage the electronics inside pacemakers.

3. The ambient temperature for siderail shuttering magnet must be below 80 °C / 176 °F, or better below 60 °C / 140 °F. General siderail magnet is designed for operation with temperature below 80 °C / 176 °F, because in the precast concrete element production only the curing process might require high temperature, and normal around 60 °C / 140 °F. If your production requires higher temperature, please tell us, and then we may customize appropriate side rail magnets for you.
