The utility model relates to a device for storing hard isolating guardrails, particularly to a support for storing the hard isolating guardrails. The support comprises a square bottom plate, wherein vertical rods are vertically fixed on two adjacent corners of the square bottom plate; a first cross beam and a second cross beam are fixed between the two vertical rods; paired transverse rods located above the square bottom plate are fixed on the first cross beam at intervals; paired transverse rods located above the square bottom plate are also fixed on the second cross beam at intervals; distances between the paired transverse rods are larger than diameters of vertical rods of the hard isolating guardrails; fixing positions of the transverse rods on the second cross beam correspond to those of the transverse rods on the first cross beam; and U-shaped clips are also clamped onthe paired transverse rods on the first cross beam. The support for storing the hard isolating guardrails has the advantages as follows: firstly, the number of the stored hard isolating guardrails is clear at a glance; secondly, the hard isolating guardrails are stored tidily and regularly, so that the hard isolating guardrails are not easy to damage and lose; thirdly, thesupport is convenient to operate.
