Abstract:

古建筑是我国的重要历史和文化遗产，而木结构是其中的主要结构形式。结构中的木梁会在其服役期间产生腐朽、开裂及拔榫破坏，因此需要对其进行必要的修复加固。已有的许多加固方法能在一定程度上对梁有修复效果，但均有其局限性，而自攻螺丝修复加固木梁的方法由于其良好的修复效果和对外貌毫无影响的特点，能广泛应用于古建筑木梁的加固，但需进行进一步深入的研究。
Historical buildings are important historical and cultural heritage in our country, in which timber buildings are the main structural styles. Timber beams experience destruction of decay, fracture, and pulling out during the service. So it is necessary to reinforce the beams of historical buildings. Many existing reinforcement methods have a good effect to a certain extent, but they all have li-mitations and cannot be widely used. The method of reinforcing beams using self-tapping screws has a good reinforcement effect and no effect on the external appearance. However before widely used in reinforcing historical building beams, there is a need for further deeply study.
