    建筑旧木方等级划分与用途

            2026-10-31 10:33:44        212次浏览

    回收回来的建筑木料,一般会按照品相分成不同等级,分级使用才能发挥价值。一级旧木方整体笔直,开裂少,钉孔不多,经过拔钉、简单修整之后,可以再次回到工地,用作模板龙骨、临时支撑,是复用价值的一类。这类木料经过前期使用自然风干,含水率稳定,不容易后期翘曲变形。二级旧木方存在少量弯曲、短截,无法直接做主体支撑,适合裁切加工成托盘脚墩、包装箱龙骨、设备垫木,也可以用在小型构件支模、地沟模板。三级废旧木材,断裂、腐烂比较多,不能直接二次使用,通常粉碎加工,作为人造板原料、生物质燃料或者食用菌培育基质。

    分级的时候要严格把控底线,腐烂严重、内部空心的木料,严禁再次用于承重支撑位置,防止施工坍塌隐患。不同品级分开存放,方便按需调配,减少资源浪费,契合木料循环利用的思路。
