大面积砼地面超平铺摊一次成型技术

Tiled concrete floor over a large area spread over a molding technology

大面积混凝土地面平整度控制是施工难点,国家规范仅对3m靠尺实测要求平整度≤5mm作了明确,目前这个规定已不能满足特殊地面对平整度的要求。我们在施工中有效地制定了控制措施和采取激光控制技术,达到大面积混凝土地面平整度极差不超2mm/3m的合同目标,从而解决了地面空鼓、起壳、开裂、不平等问题,达到了大面积超平地坪质量要求。

Large areas of concrete floor flatness control is the construction difficulties,the national standard requirements only measured 2m by foot flatness ≤ 5mm made clear,the current provisions have been unable to meet the special requirements of face flatness.We are in the construction of effective control measures and to develop a laser control technology to achieve a large area of concrete surface roughness does not exceed 2mm/3m poor contract goals.So as to solve the ground hollowing from the shell,cracking,inequality,to a large area over ground floor quality requirements.
