在工程实践中发现大量砌体结构出现裂缝,轻者影响美观,重者影响使用;因此对已开裂的砌体结构如何进行加固与处理显得非常迫切。砌体结构是指由块体和砂浆砌筑而成的墙、柱作为建筑物主要受力构件的结构。特点是整体性较差,抗拉和抗剪强度较低,比较容易产生裂缝。但砌体结构裂缝有一定原因和客观规律。通过对砌体结构裂缝和变形的分析,可以提出有针对性的预防和处理措施。结合我国当前国情,对砌体开裂提出了一些预防加固措施,同时也为施工和设计人员今后预防砌体开裂积累一些有益的经验。
In engineering practice, a large number of cracks appeared in the masonry structure, the lightness affects the appearance, and the heavier ones affect the use. Therefore, it is very urgent to reinforce and treat the cracked masonry structure. Masonry structure is a wall made of blocks and mortar masonry, columns as the main structure of the force components. Characterized by poor overall, tensile and shear strength lower, more prone to cracks. However, the cracks in masonry have some reasons and objective laws. Through the analysis of cracks and deformation of masonry structure, we can put forward targeted prevention and treatment measures. Combining with the current national conditions in our country, some measures for prevention and reinforcement of masonry cracking are put forward. At the same time, some beneficial experiences are accumulated for the construction and design personnel to prevent cracking of masonry in the future.
