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

Abstract

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

Description

technical field [0001] The invention relates to a building concrete exterior wall, in particular to an ultra-thick basement exterior wall, and a construction method for the exterior wall. Background technique [0002] The construction of the exterior wall of the basement of the building usually adopts the form of concrete pouring. Because the temperature of the heat of hydration rises and falls too fast during the solidification process of the exterior wall concrete after pouring, the surface of the concrete loses water and shrinks, which is easy to cause cracks in the wall. The increase in the amount of cement not only increases the construction cost and prolongs the setting time, but also increases the activity of the cement, decreases the volume stability, and easily leads to shrinkage and deformation. There are many factors that are difficult to control for the cracks in the external wall. In addition to the structural problems of the basement, there are also factors suc...
