摘要:
通过对连接件与可拆式钢筋桁架模板在施工阶段下的力学性能试验研究,研究表明大跨度可拆式钢筋桁架模板需要施加临时支撑,建议采用连续梁模型计算和施工;试件破坏过程由变形控制,而非承载力控制;上弦钢筋直径和试件尺寸对试件的承载力和变形产生影响;并对连接件的承载力进行相应的修正,得到连接件的设计值;利用可拆式钢筋桁架模板可以大大减少支模工程量,加快施工进度,与其他楼板体系相比具有经济、节能环保的优势.
Abstract:
Mechanical behaviors of connectors and detachable formwork with steel bar trusses under construction stage are analyzed by the test. The results show that large span detachable template with steel bar trusses need to impose temporary support, for which the model of continuous beam is suggested for calculation and construction. Corresponding advice is proposed for acquiring the design value of the maximum length of no-support. The specimens’ failure process should be controlled by deformation rather than bearing capacity. Upper chord bar diameter and specimens’ size have effect on the load-carrying capacity and deformation of the specimens, which help amend the load-carrying capacity of connectors and getting fitting design value. Using detachable template with steel bar trusses can cancel the formwork engineering, and greatly speed up the construction progress. Compared with other slab system it has the advantage of economy, environmental protection and energy saving
