Temporary prestressed waist beam capable of continuously applying counterforce for surface plate

The invention relates to a temporary waist beam and specifically a temporary prestressed waist beam capable of importing and adding counterforce for a surface plate. The temporary prestressed waist beam capable of importing and adding counterforce for the surface plate is that the quantity of all steel materials are less than that of the traditional supporting waist beam; the construction economy is increased; the waist beam is extended, and the safety of the waist beam is improved; ground construction and structure arrangement in later works are simple and convenient; the construction can be reduced; the construction efficiency can be increased. The temporary prestressed waist beam capable of importing and adding counterforce for the surface plate is characterized in that vertical plates with a certain spacing are arranged; the waist beam passes through the vertical piles; a supporting seat for fixing and supporting the waist beam is equipped with a horizontal beam in the temporary waist beam of the surface plate, and the horizontal beam passes through the waist beam; weight PS steel wire fixing brackets are fixedly arranged at two ends of the horizontal beam; a PS steel wire bracket arranged between the weight PS steel wire fixing branch is used as a prestressed importing device; a PS steel wire is lapped on the weight PS steel wire fixing bracket and the PS steel wire supporting seat which is used as the prestressed importing device.
