Abstract
A floor frame includes at least two spaced longitudinal support strips and at least one lateral support strip. Each longitudinal support strip has longitudinal upper and lower portions and a pair of longitudinal side walls. A shoulder is designed on at least one of the pair longitudinal side walls and located between the longitudinal upper and lower portions. Two shoulders of the two longitudinal support strips are opposite to each other. The lateral support strip includes lateral upper and lower portions and a pair of lateral side walls. Two ends of the lateral support strip are placed on the two shoulders of the longitudinal support strips, respectively. A plurality of longitudinal and lateral support strips constitutes a grid-type structure under the distribution of longitudinal and lateral directions to provide the placement and fixation of a plurality of floor panels.
