近年来伴随宁夏地区建筑业的蓬勃发展,掺加大量外加剂的商品混凝土(集中搅拌)已广泛应用于建筑工程,尤其是大型公共建筑和高层住宅,随之而来混凝土裂缝已成为工程质量的通病。现就预防地下室钢筋混凝土墙板竖向裂缝的措施做以下探讨。1设计方面1)由于宁夏地区早晚温差较大,对《混凝土结构设计规范》GB50010-2002规定的后浇缝最大间距不宜
In recent years, with the vigorous development of the construction industry in Ningxia, commercial concrete with a large amount of admixture (concentrated mixing) has been widely used in construction projects, especially in large-scale public buildings and high-rise houses, and subsequently the concrete cracks have become engineering quality Common problem. Now on the basement to prevent vertical cracks in reinforced concrete wall measures to do the following discussion. 1 Design 1) Due to the large temperature difference between morning and evening in Ningxia, the maximum spacing of after-pouring joints stipulated in “Code for Design of Concrete Structure” GB50010-2002 should not be exceeded
