ABSTRACT:
A method and apparatus for connecting modular structures include I-beams which are placed beneath and longitudinally perpendicularly to the integral longitudinal supporting beams of the modular structures. A pair of upper plates and a pair of lower plates are positioned with respect to the upper beams and the lower I-beams, respectively. Bolts are passed through the upper plates and the lower plates, and nuts are tightened on the plates to cause the upper and lower beams to be clamped together. The plates are installed on the beams without requiring any structural modification of the beams, such as, for example, cutting, drilling, welding, or the like. Thus, the beams are not weakened by the process, and the modular structures can be readily disconnected and transported to another location for reconnection. The method and apparatus also include support structures which support the lower beams and which can be adjusted to comply with variations in the elevation of the ground or platform on which the modular structures are located. As with the interconnecting plates, the support structures are installed without requiring any structural modification of the beams.
