MA bracket consists of a group of welded elements formed by two steel plates, a hexagonal nut and a threaded bar used for supporting precast concrete panels.

 

 

Inside the concrete panel, there is embedded a CMA recess where there is placed the MA threaded bar. Therefore, the weight of the concrete panel is transmitted from the recess CMA to the bracket. Finally, the MA bracket is fixed to the concrete slab through an expansive anchor or by means of welding.

 This support typology permits having a regulation on the three main axes:  vertically, it is adjustable through the threaded bar; horizontally, is adjustable through the CMA; in depth, is adjustable with the slotted hole of the MA.

 Apart from the support bracket MA, it is needed to place an anti-roll system such as an UPA or COFI to avoid the overturning of the concrete panel.
