Mass Concrete Tie Fabrication
We wanted to be able to producte at least 270 ties each session. So we use 9 pieces of plywood, 3/4" thick by 2' x 8' with 30 tie molds or forms on each one. When setting up the molds on the plywood keep the molds tight together. That makes pouring the concrete faster and easier and concrete will not get between the forms.
Below: This is what the plywood looks like without the individual tie forms or molds on the pegs.
Below: This is what the inside of the molds look like when they are in position on the gang form plywood prior to the loading of the inserts. Notice some are set up for 4 insert or screws
Below: Don Smith and Pete Pedigo are sorting the molds and placing them back on the gang form plywood after removing ties that we cast the day before.
