Construction technology for hollow super-thick concrete terrace
The invention provides a construction technology for a hollow super-thick concrete terrace. The construction technology comprises the steps of 1, constructing a brick die and a cushion layer, 2, banding and installing steel bars of a base plate and ribbed beams, 3, pouring base plate concrete, 4, installing and pre-pressing box molds, 5, banding and installing steel bars on the upper portion of a floor, and 6, pouring and maintaining concrete on the ribbed beams and a face plate. The construction technology is substantively characterized in that in the step 5, after the steel bars on the upper portion of the floor are banded, a cushion block is additionally arranged between the top of each box mold and the steel bars of the upper portion of the floor, the box molds are pressed, each box mold is connected with the steel bars on the upper portion of the floor and the bottom steel bars of the ribbed beams in a tied mode through tie bars on the four corners of the box mold, and the inner molds are prevented from moving. The construction technology has the advantages that terrace concrete is poured twice, the primarily poured concrete base plate is effectively combined with a steel bar framework of the ribbed beams, the buoyancy force of hollow inner molds of the super-thick concrete terrace is transferred to the ribbed beams firmly combined with the base plate concrete, construction of special anti-floating anchoring steel bars is omitted, the construction process is simplified, materials are saved, and the construction quality is easily guaranteed.
