Outside the prefabricated concrete slab is a trimly precast formwork which fixed by shuttering magnet boxes. The use of the precast magnet box do not need any weld works which takes high consumption electricity. Magnet for precast concrete is made up of big neodymium magnet and steel. There are two hex bolt for fixed with adapter and a push button on the top. Set the magnet to precast formwork then just one down push at the round handle button, the magnet will sink and catch the steel panel. The remove of the magnet require a magnet crowbar(magnet lifting lever). Advantages of using concrete magnet - Workers could quickly build concrete formwork according to individual architectural design. - Workers could contemporaneously build different concrete formworks in one time. - Even during the building process,workers could adjust the concr…
