PURPOSE: An expansion member for a support of a floor slab form is provided to improve the operation efficiency of a floor slab installation construction by equally distributing the load of poured concrete and to secure the floor slab of good quality by flexibly supporting the slab form by mounting a shock absorbing member having a spring to an upper bearing plate of the support for supporting the floor mold to construct a reinforced concrete slab. CONSTITUTION: In a shock absorbing member(A) installed to a bearing plate of a support having a supporting plate at the floor to support the lower side of a mold, an expansion member for the support of a floor slab form is composed of the shock absorbing member comprising upper and lower supports(1,2) having a plurality of combining holes(11,21); hollow supporting cylinders(12,22) of which some portions are mutually overlapped, formed at facing sides of the upper and lower supports, respectively; and a plurality of hanging tools(13,23) installed in the supporting cylinders. Combining units(31,32) formed at both ends of a coil spring(3) in a plane shape are inserted and combined to the hanging tools.
