侧向木质支撑技术在地震灾害建筑坍塌救援中的应用

Application of Lateral Timber Shoring Technology in Collapsed Buildings After Earthquake

据统计,在发生地震灾害建筑坍塌后有30%受灾人员被困于坍塌后的混凝土楼板、墙体、柱子、梁等构成狭小受限空间内。消防救援人员在进行搜救时,为保障救援工作时的安全,防止发生二次坍塌,减小被困人员和救援人员的危险,通常需要对那些局部受到破坏或者不稳定的建筑结构做临时的支撑。侧向木质支撑技术是木质支撑技术主要实用技术之一,本文就侧向木质支撑制作程序、技术要点和注意事项进行阐述。

According to statistics,after the building collapse triggered by earthquake,30%of the victims were trapped in the narrow and confined space made by concrete slabs,walls,columns and beams.When carrying out search and rescue,firefighters usually need to make temporary support to those partially damaged or unstable structures in order to ensure the safety of rescue work,prevent secondary collapse,and reduce the risk of trapped people and rescuers themselves.Lateral timber shoring technology is one of the main practical technologies of wood support technology.This paper expounds its production procedure,technical points and matters needing attention.
