Cast-in-situ concrete hollow exterior wall and construction method thereof

摘要: The invention relates to a cast-in-situ concrete hollow outer wall and construction method thereof. comprises body reinforcing steel bars inside the body, wherein of is set into whole through thin pipes arranged vertically side by at intervals around pipes; two ribs along length direction are horizontally distributed with limiting outside respectively; short between ends bonded insidethe respectively whole. thereof can effectively shorten period, reduce resource consumption, use environment-friendly materials lower comprehensive cost, material consumption in large quantity, further hydration heat temperature difference generated cast process volume concrete, avoid generation cracks, correspondingly save constructional bars.
