21 <br /> 4.7.4 Joining adjacent Wallforms <br /> Always make certain that the male and female ends of the wallforms mate properly. They are <br /> designed to fit together tightly, assuring maximum insulation value and fire resistance. Fasteners <br /> (nails, screws, construction adhesive, etc.) are generally not needed to join wallforms. There are <br /> occasions when gapping occurs between wall forms that will require the use of a galvanized <br /> fastener, or adhesives to close gaps. Later, when walls are erected it is recommended to foam any <br /> gaps>3/16"with a non expanding urethane foam adhesive on both inside and outside surfaces. <br /> 4.7.5 Cutting the last Wallform in each course <br /> Build the walls in from the corners. In most cases the last wallform in each course will need to be <br /> custom cut to fit due to the slight growth in the wall as you stack the wallforms end-to-end <br /> (approx. '/z-3/4" every 20') . The best method is to cut off the end of the filler wallform, shorten <br /> the wallform, then re-attach the end using screws. This returns the structural strength of the <br /> modified wallform. Proper attention to this detail will assure that the cut wallform will hold up <br /> when the forms are filled with wet concrete and that the insulated side is sound. <br /> 4111, <br /> Step 1: measure gap to fill <br /> r ' � <br /> Step 2: cut off the end of the `filler wallform' <br /> Step 3: Cut the wallform to the appropriate length[remove insert, cut separately) <br /> Step 4:Re-attach the end of the wallform using 3.5"galvanized or ceramic coated screws: <br /> Step 5:Install in wall - - I <br /> ShelterWorks General Application and Technical Information(GATI)version 2.5 <br />
