Utility Model Nº U201120358
The concrete spacers JM has been created to be used in pillars and vertical surfaces. The model consists of two pieces, one concrete wheel and one locking piece that makes easy and fast the collocation at the formworks. Its function is to separate the armors from the formworks, making it ideal for uniform coating and at the same time avoiding displacements during vibration.
Concrete, vibrated, pressed and cured in a controlled atmosphere (temperature and humidity). One or two metal clamps or piece of polyethylene the same purpose.
Rough and irregular, for adherence and full integration.
Circular transverse recess which houses a locking device. Easy to put on own work.
