What are precast concrete elements?
Concrete precast components are widely used in the construction industry and are used in exterior walls, interior walls, stairs, floors and other areas of houses. If distinguished by building type, it can be used in buildings such as residences, bridges, industrial plants, and public facilities. As the name suggests, concrete precast components are produced in a prefabricated factory building by using formwork and then pouring concrete into shape. Of course, concrete precast components can be built according to the engineer's drawing requirements, and functions such as pipelines and sockets can be laid out in the component body to prepare the layout in advance. Once the concrete precast components are transported to the construction site, the building can be quickly erected, greatly improving the construction process.
What is a precast concrete magnets?
The concrete shuttering magnet is one of the key accessories in the precast concrete system. Used to support side rails and blocks while pouring concrete. Concrete Shuttering magnet box is an important component of prefabricated magnet products, it is the key to providing suction. If you could open the magnetic box, you would see the parts shown in the picture below.
Illustration of the components and its main functions of concrete shuttering magnet box
In addition to its metal shell, the next larger component of the magnetic box is the magnet block that provides suction. It is composed of metal and magnetic materials. Depending on the size of the attraction, it is divided into ferrite magnets and NdFeB magnets with greater magnetic attraction. Ferrite magnetic materials are cheap and have low magnetic attraction. The price of NdFeB magnetic material is equivalent to 10 times that of ferrite magnets, but the magnetic attraction provided is also much improved.
How neodymium precast shuttering magnet works?
The magnetic array is the core part of the entire concrete shuttering magnet. The special magnetic circuit composed of sintered NdFeB magnets and conductive magnetic sheets will produce strong suction. In addition to the distance between the magnetic array and the mold table, the suction force of 2100kg shuttering magnets is also affected by the thickness and surface roughness of the Concrete Formwork.
In addition, we can see a black cylindrical object in the middle of the top surface of the magnetic box, which is the clamping handle. After pressing hard (you can hit it with a hammer), the magnet block will fall and come into contact with metal objects (casting workbench and lathe on the steel surface) to generate suction, so that the magnet is firmly attracted to the steel plate workbench. If you need to separate it from the metal object, use a crowbar (using the principle of leverage) to lift the clamping handle. This is the working principle of Concrete Plant Precast Technology. During the pressing and prying operation of the clamping handle, the concrete component formwork is fixed and separated as the magnetic attraction increases and weakens. Concrete Formwork is the process of giving support and stability to concrete before it hardens. Strong, well-positioned Formwork helps shape and strengthen concrete. Concrete shuttering magnet is suitable for any type of formwork material. It can be used on cast tables and lathes with steel surfaces.
Crowbar used to lift clamping handle
There are also 2 screws at both ends of the top surface of the magnetic box, which are used to fix other side rails and stops. For example, you can use an L-shaped metal template to be fixed in these two screws to make the L-shaped template firmly fixed. Through this flexible fixing method, various shapes of formwork can be used to fix the concrete components to be produced.
How to operate a concrete shuttering magnet?
1. Place the Magnetic Formwork System at the position where the formwork table needs to be fixed;
2. After pressing the switch, check whether the magnetic box is adsorbed on the mold table;
3. Use a professional crowbar to lift the clamping handle. Since the magnetic array is separated from the mold table, the adsorption state is released;
4. Fixing screws can be used to fix different types of side molds and fixing fixtures.
What are the benefits of using concrete shuttering magnets?
High Forces Precast Concrete Shuttering Magnets' powerful magnetic attraction allows the concrete to maintain its side shape during casting and shaking. The strength of concrete components is closely related to the forming process. The bearing capacity of poorly shaped components will be weakened. Precast Concrete Magnet is fast to operate, improving efficiency during concrete form placement and removal. Because Shuttering Magnet can be positioned very accurately, it will reduce the complexity of concrete formwork layout and installation time.
How to check the on off state of the shuttering magnet box ?
The shuttering magnet can be closed by pressing the clamping handle firmly or hitting it with a hammer. At this time, there should be no gap between the 1000kg shuttering magnet and the steel surface workbench. The magnetic attraction of Super Magnets also makes the magnetic box firmly grasp the steel surface and fixed template. You can grab the magnetic box firmly to see if it moves, if it's unusually firm it's closed.
What are the daily maintenance instructions for the concrete shuttering magnets?
1. Magnets are fragile. Please avoid damage to the magnets and external impacts as much as possible.
2. Please pay attention to keeping the working surface of the magnet array clean and remove concrete residue, iron filings, dirt, etc.
3. Prevent the clamping handle from being damaged and unable to work due to the intrusion of iron filings and concrete.
4. It is necessary to carry out appropriate anti-rust treatment, apply grease and protect the magnet.
5. Wear protective equipment when using large magnets. Large magnets have strong magnetic force and improper operation may injure your fingers.
6. If you have any questions, please contact Magnetic Formwork System Supplier.
7. Magnets should be kept away from electronic devices and magnetic objects, such as pacemakers, mobile phones, iPads, computers, magnetic cards, etc. Magnetic fields can damage these things.
8. The maximum working temperature of conventional magnetic boxes should not be higher than 80°C, otherwise the magnetism will decrease or disappear.
