Opening and breaking up materials 3.3
The spike, hammer and flat wedge can be used as striking tools.
Thin plates
An opening in a plate is created by striking with the spike. If larger
openings are required then a number of holes can be made in a
row. An axe or split hammer is then used to join the holes made
by the spike.
Chip boards
Chip boards can also be opened with a row of holes which
are then joined by cutting.
Sandwich plaster boards
Produce a row of holes with the spike and hit out large pieces with
the hammer area. Note : Plaster board can contain electrical wi-
ring!
Single glass, flat glass
Break the glass sheets going from the top to the bottom using the
hammer area. Doing this , stand to one side of the window being
broken.
Single sheet safety glass, automotive windscreens
Using the spike, the sheet is broken around the edge area, the
glass then breaks into pieces.
Wire reinforced glass, compound glass
An opening firstly made with the spike, after doing this the flat
wedge can be used hitting from a side position or knocking in the
cut line from the front with the brace wedge.
Single row walls made of hollow blocks, bricks, glass bricks or ae-
rated concrete blocks can also be broken up. The first block should
be removed using the spike like a pickle. The other blocks can
then be broken up with the brace wedge or knocked out with the
hammer.
Openings made in brick walls must always have
the shape of a square standing on the tip so
the remaining bricks can support each other.
