The utility model solves the technical problems by the following technical proposal:

the utility model provides a cantilever unidirectional limiting temporary construction supporting device of a large-span steel structure, which is characterized by comprising steel lattice columns positioned at two sides, wherein supporting bases are fixed at the tops of the steel lattice columns at two sides, limiting columns are respectively fixed at two ends of the supporting bases, joists are fixed between the upper parts of the opposite inner sides of the two limiting columns, supporting columns are respectively arranged below the two ends of the bottom of each supporting column positioned on the supporting bases, each supporting column is arranged between the two limiting columns, a plurality of first flexible base plates are arranged between the top of each supporting column and the bottom of each supporting beam in a cushioning mode, slots are formed in the tops of the supporting beams, limiting plates are respectively fixed at the tops of the supporting beams and positioned at two sides of the slots, vertical jacking columns are inserted in the slots, a second flexible base plate is clamped between each limiting plate and each vertical jacking column, and the tops of the vertical jacking columns are used for jacking steel members.

Preferably, the top surface of each of the vertical jacking posts is parallel to the bottom surface of the steel member.

The utility model has the positive progress effects that:

this one-way spacing interim construction strutting arrangement can effectively support the construction of encorbelmenting of large-span, and the structure jacking post is contacted with steel member parallel, utilizes to increase or reduce flexible backing plate and limiting plate restriction, and adjustable structure jacking post one-way slides, and then stability and the convenience of supporting the uninstallation in the control steel construction work progress.
