specific practical dimensions are given however it is to be understood that these dimensions may vary with the size of the modules the height of the building and other factors to provide the desired building strength fig7 shows the wall connection of two interior modules stacked on top of each other the steel angles 35 studs 37 and field welded plate 38 and its weld 39 are identical to that shown in fig5 a fig8 shows the wall connection of the exterior wall 45 of two modules stacked on top of each other this connection should be made from the inside of the module so that scaffolding would not be required on the outside it consists of the same type of plate 41 and stud 42 as in fig6 cast into the bottom of the module floor 36 the wall has an angle member 35 with a diagonal stud 37 cast into the top of the adjoining wall with a 30 mm gap 46 a plate 43 of the same size as in fig6 is then welded in the field in the same manner as in the previous details fig9 shows the attachment of the bottom floor 46 of modular units either to a foundation wall or the slab 47 of a building podium the connection of a non bearing exterior wall panel 48 is also.
