Abstract
Explosive bullock with an external shape analogous to that of an ordinary bullet but inside and opposite to its head it has a cavity in which a small explosive charge is lodged with which the bullet is inserted in the corresponding holes in the cold. The sheets to be joined are enough to warm the head of the plank so that the load explodes, widening the plank by strongly compressing the sheets, forcing the entrance hole to be expanded to a conical shape that is completely filled by the material it is constructed from the grout and causing the pressure to be transmitted in the normal direction to the sheets, greatly increasing their adhesion.
