龙江省地区处于寒冷地区，冬夏温差变化很大，由于设计与施工等原因，造成女儿墙根部相继产生不同程度的水平裂缝。1剖析原因1．1保温层上找平层抹的过厚，又抹到女儿墙根部超厚，造成一个坚硬的壳体，产生了水平推力。1．2女儿墙在砌筑时，没按设计要求1500mm设构造柱，也没设 Longjiang Province is in a cold area, and the temperature difference between winter and summer changes greatly. Due to design and construction reasons, the roots of the parapets of the parapets have successively generated horizontal cracks of varying degrees. 1 Analysis of reasons 1.1 leveling layer on the insulation layer is too thick, and wiped the parapet root thick, resulting in a hard shell, resulting in a horizontal thrust. 1.2 The parapet was not constructed according to the design requirement 1500mm when the parapet was masonry.
