摘　　要：年久失修的古木建筑因长年受到风雨侵蚀及人为损坏,构件会有不同程度的糟朽、腐烂,产生结构安全问题且修复难度极大,特别是严重倾斜的木结构门楼。本文通过在门楼的重檐一侧施加外部作用力,将屋顶结构整体提正,临时卸载释放下部支撑主梁的应力,然后采用填充灌注环氧树脂方式修复木结构受损部位,并在受剪集中且糟朽严重位置粘结钢板,同时利用螺栓把钢板与木材压紧,使其结合成为新的组合结构承载重檐屋顶结构的荷载,完成了木结构建筑的加固与主动纠偏复位。研究结果表明:运用打牮拨正与钢木组合加固结构的协同修复工艺,对倾斜的古木建筑能够有效纠偏复位,对糟朽的木构件能够有效修复且提高结构强度,还原古木建筑原貌的同时加大了其结构的安全性。该研究为倾斜失修类古木建筑的维修提供了一种有效的方法和实际应用参考。Due to the long-term erosion of wind and rain and human damage,the ancient wooden buildings,which have been neglected for a long time,will have different degrees of decay and decay,resulting in structural safety problems and great difficulty in repair,especially for severely tilted wooden structure gate towers.This study used external forces on the side of the eaves of the gate tower to lift the roof structure as a whole,temporarily unload the stress of the main beam supporting the lower part,and then use epoxy resin to fill and pour to repair the damaged parts of the wooden structure,and glue steel plates at the positions with concentrated shear and severe decay,and use bolts to press the steel plates and wood,so that they combine into a new composite structure to bear the load of the gable roof structure,thus completing the reinforcement and active correction of the wooden structure.The research results show that the collaborative repair technology of using shoring and steel-wood composite reinforcement can effectively correct the tilt of the ancient wooden buildings,effectively repair the decayed wooden components and improve the structural strength,restore the original appearance of the ancient wooden buildings and increase their structural safety.This study provides an effective method and practical reference for the repair of inclined and neglected ancient wooden buildings.
