摘要
针对砖木结构历史保护建筑存在的墙体砌筑砂浆或砌体强度低、梁混凝土强度低、木楼盖承载力较低等问题,提出了砖砌体墙采用高延性混凝土面层加固、混凝土花篮梁采用双槽钢夹梁法加固的技术,阐述了加固设计方法和实施的注意事项,对历史保护建筑的加固设计有参考意义。
In response to the problems of low wall masonry mortar or masonry strength,low beam concrete strength,and low bearing capacity of wooden building covers in historical protected brick and wood structures,this paper proposes the technology of using high ductility concrete surface layer reinforcement for brick masonry walls and double channel steel clamping method reinforcement for concrete flower basket beams.The reinforcement design method is given,and the precautions for reinforce-ment design and implementation are elaborated,which has reference significance for the reinforcement design of historical protected buildings.
