Abstract

本实用新型公开了一种绿色木屋架端部节点碳布加固结构，涉及木屋架裂缝修复技术领域，该木屋架端部节点加固结构，包括下弦杆和对穿螺栓，所述下弦杆的两侧设置有新增木材，所述新增木材的下端及外侧设置有加固组件，所述加固组件的一侧设置有既有砌体墙，且新增木材及下弦杆通过加固组件与既有砌体墙固定，所述下弦杆的表面设置有裂缝，所述加固组件包括角钢，碳纤维布环箍，且角钢设置有四个，并且新增木材位于两个角钢之间，本方案解决了现有木屋架在进行裂缝修复的时候，直接一般为更换相应杆件，或者用专用胶嵌补裂缝，又或者采用长钉加固，存在下弦杆承载力不足，屋架端部与既有砌体多为直接搁置，有滑移风险的问题。
