to a substructure referring to fig3 in step 300 a user places one or more alignment stoppers on a beam in step 310 a user places an adapter as desired on chosen ones of the alignment stoppers in step 320 the user places at least one panel on the alignment stopper and adapter so that the panel is engaged with the stopper and adapter in step 330 the user places additional panels on the stoppers and adapters until the user has completed construction of the portion of the panel structure or floor desired to be constructed with the adapters fig4 depicts alternate embodiments of the adapter which may be implemented as desired the shapes arc purely illustrative only and changes may be made to the shapes to meet design cost or other goals referring to fig4 a an adapter is picture m which one side of the adapter has one profile and the other side has a different profile the adapter continues to have a central cutout designed to receive a top flange of an alignment stopper the adapter 400 may be used to join a panel such as that shown in fig1 with a panel such as that shown in fig2 fig4 b depicts an alternative embodiment of the adapter referring to fig4 b the adapter includes a flange instead of a cutout such an adapter may be deployed when the substructure or alignment stopper instead of a top flange includes a top cutout instead the flange of the adapter may then fit into the cutout of the substructure or the alignment stopper the adapter may be made of plastic metal or any other desired material while particular embodiments of the present invention have been shown and described it will be understood that changes may be made.
