Abstract

A combined type shelf includes parallel-rod side frames, inter-frame connectors, storage layers and horizontal constraint frames. The parallel-rod side frame includes a first vertical bar, a second vertical bar and a horizontal bar. The inter-frame connector includes a connector body, two lateral plates, a hole and lower interference parts. The storage layer is disposed between two horizontal constraint frames. The horizontal constraint frame includes a horizontal stop member and a constraint-frame coupling member. The constraint-frame coupling member includes upper interference parts to buckle the lower interference parts so as to connect the horizontal constraint frame to the inter-frame connector.
