碗扣支架支撑体系在系杆拱桥梁体施工中的应用

满堂支架施工是一种传统的施工方法。它具有多功能、高功效、承载力大、工序相对简单等特点,在桥梁施工中被广泛应用。作为现浇梁体施工的一个关键工序,支架必须保证具有足够的安全性。因此,对满堂式支架的各层次进行详尽合理的设计计算显得尤为重要。现结合满堂式碗扣支架在系杆拱桥梁体施工中的成功应用经验,介绍一下满堂式碗扣支架的设计验算和施工工艺1-4]。

Application of Bowl Buckle Support System in Girder Construction of Bowstring Arch Bridge

The full-framing construction is a conventional construction method with the characteristics of many functions,high efficacy,large bearing capacity and simple constructing procedure.This method is widely used in the bridge construction.As a key constructing procedure of cast-in-situ girder,the support must guarantee the enough safety.Therefore,it is very important to carry out the reasonable design and calculation of all levels of full framing.Combined with the successful application experience of full-framing bowl buckle support in the girder construction of bowstring arch bridge,the design checking calculation and the construction technology of full-framing bowl buckle support are introduced.
