1.What is Shuttering Magnet?

The precast concrete fixed shuttering magnetic is one of the most important precast concrete magnetic components, and its main function is to fix the side form on the formwork table during the concrete pouring process. Precast concrete fixed shuttering magnet structure The working principle of precast concrete fixed magnetic box The magnetic array is the core part of the whole precast concrete fixed shuttering magnet. The special magnetic circuit composed of sintered NdFeB magnets and conductive magnet pieces will generate a strong suction force. The suction force of the precast concrete fixed magnetic box is not only affected by the distance between the magnetic array and the mold table, but also affected by the thickness and surface roughness of the mold table. Compared with the traditional bolt fixing method, the template magnet has the characteristics of quick disassembly and assembly, flexible operation and strong fixing force, which effectively improves the performance of the template magnet. Due to high labor efficiency and low die loss, it is widely used at home and abroad.

2. What is Structure of Shuttering Magnet?

The magnetic box is assembled by high-performance strong magnetic NdFeB magnetic components, spring screw connection accessories, stainless steel 201 or 304 buttons, and shell.

3. What is the Principle of the Shuttering Magnet?

Using the adsorption force between the NdFeB strong magnetic core and the steel mold table, it is transmitted to the stainless steel button switch through the connecting screw to perform the opening and closing operation of the shuttering magnetic. The design of unilateral or bilateral bayonet can be directly clamped on the L-shaped angle steel side mold. The double side is equipped with 8.8 high-strength, adjustable fastening screws, which can be directly pressed down to fix the steel side mold, thereby strengthening the shuttering magnet. The connection with the angle steel can effectively prevent the mold from being displaced.

4. How to Choose the Shuttering Magnet?

When selecting formwork magnets, precast concrete manufacturers need to pay attention to the usage scenarios of the magnet box. Please see our standard shutter magnet sizes here.

5. How to Use the Shuttering Magnet?

①When in use, move the magnetic box to the appropriate position to be fixed, and press the button to make the magnetic core firmly adhere to the steel mold table. At the same time, the bayonet clamps the steel side mold and tightens the side screw. Or use other connection accessories to complete the fastening and complete the installation.

②When the production of the components is completed, it is necessary to borrow a professional magnetic box crowbar, pry up the button, and release the magnetism of the magnetic box, so as to complete the disassembly or displacement of the magnetic box.

6. Shuttering Magnetic Application:

Magnetic boxes are commonly used in most molds such as steel molds, aluminum molds, plywood wooden side molds, etc., and are placed on steel mold tables to produce various precast concrete components. Widely used in the production of prefabricated stairs, exterior wall panels, interior wall panels, balconies and other prefabricated components.

APPLICATION

7. What Should Pay Attention to When Using the Shuttering Magnet?

①The tightening nut cannot be lowered, otherwise the magnetic box body is pushed up too much and the contact surface is too large, resulting in insufficient adsorption and side displacement.

②The surface of the steel mold on which the magnetic box is placed should be flat, and it should be cleaned before each use. There should be no concrete residue or other particulate matter, so as not to affect the incompatibility of the magnetic core and the mold table and affect the fixing strength.

③ Before and after the use of the magnetic box, the contact surface of the magnetic core should be cleaned, and no concrete and iron filings can stick to it, which will affect the adsorption force.

④ Always clean the concrete stuck on the body and apply oil, and regularly add oil to the guide rod position to ensure the smooth opening and closing of the magnetic core.

⑤ It is forbidden to hit the body with a hard object such as a hammer, or fall freely to the steel surface from a high place, otherwise the strong adsorption force of the magnetic core itself may damage the box body and affect the use, and even cause the magnetic core to dislocate and damage the magnetic box.
