To provide a temporary connecting member which can effectively and continuously perform the function to prevent a trouble such as falling down of a structure related to underpinning does not develop cracking in the lower end part of the structure or in the upper end part of a lower supporting beam by vibration, and can follow up the displacement of the structure caused by jacking up.
A columnar member (an upper channel 5) is slidably close-fitted into directionally restraining members (lower channels 3) which restrain the axis of the columnar member (the upper channel 5) as viewed from at least one direction in as specified direction. The columnar member (the upper channel 5) and directionally restraining member (the lower channel 3) may be provided with a slide limiting means (a stopper member 8 and rectangular opening 7) which limits the sliding of the columnar member (the upper channel 5) within a specified range.
