现今框架、框剪结构在建筑工程主体结构中应用十分广泛,但由于混凝土柱、墙和轻质混凝土空心砌块等墙体填充材料的吸水率有着明显差别,所以不可避免的会出现不均匀沉降现象,严重的会造成在两种材料相交处出现纵向的裂缝,这种质量通病给工程竣工验收、后期维修带来很多隐患。
Nowadays, the frame-shear structure is widely used in the main structure of the construction project. However, due to the obvious difference in the water absorption rate of the wall filling materials such as concrete columns, walls and lightweight concrete hollow blocks, uneven settlement will inevitably occur Phenomenon, serious will result in the intersection of the two materials appear vertical cracks, the quality of common problems to the project completion and acceptance, post-repair brought a lot of hidden dangers.
