Construction method for blocking high-altitude limb inclined roof penetrating tower crane hole
The invention provides a construction method for blocking a high-altitude adjacent-edge inclined roof penetrating tower crane hole. The method comprises the following steps that a U-shaped anchor ring is pre-buried in the first layer of a roof; roof beams and roof panels around the tower crane hole are constructed; after the tower crane is used, the tower crane standard knot is dismantled; cantilever I-shaped steel and a protection system are erected at the hole; a formwork supporting system is erected on the cantilever I-shaped steel, chiseling and embedded steel bar binding are carried out at the concrete joint position at the hole, and a beam plate formwork is erected and reinforced; and anti-seepage micro-expansive concrete with the grade higher than one grade is poured, and the supporting system and the outer frame protection system are dismantled after the strength is achieved.
本发明提供了一种高空临边穿斜屋面塔吊洞口封堵施工方法，该方法包括如下步骤∶在屋面‑1层预埋U型锚环；塔吊洞口周边屋面梁及屋面板施工；塔吊使用完毕后，拆除塔吊标准节；洞口处悬挑工字钢及防护体系搭设;在悬挑工字钢上搭设模板支撑体系，洞口处混凝土接槎处凿毛及植筋绑扎，梁板模板支设和加固；浇筑高一标号抗渗微膨胀混凝土混凝土，达到强度后拆除支撑系统和外架防护体系。
