【摘要】：基于对高大模板支撑体系的分析,对某钢筋混凝土框架单层厂房高大模板支撑进行设计,施工过程中跟踪实测,监测在混凝土浇筑和养护过程中,支撑体系中的立杆、水平杆、剪刀撑和抱柱件的应变变化情况。实测结果表明,混凝土开始浇筑,立杆和水平杆的应变急剧上升;浇筑结束后,立杆和水平杆的应变趋于稳定;在混凝土养护约24h后,立杆和水平杆的应变明显减小,随后保持稳定。这表明,随着混凝土强度发展,梁板可以承担一部分自重,从而降低了支撑体系的负重。另外,剪刀撑和抱箍对模板支撑体系的稳定性有重要作用。现场测试结果可以为扣件式高大模板支撑体系的设计和应用提供参考。
[Abstract]:Based on the analysis of the high formwork support system, the paper designs the tall formwork support of a reinforced concrete frame monolayer factory building, tracks the actual measurement during the construction process, and monitors the vertical and horizontal poles in the support system during the concrete pouring and maintenance.Strain variation of scissors brace and clasp.The measured results show that the strain of vertical bar and horizontal bar increases sharply after concrete pouring, the strain of vertical bar and horizontal bar tends to stabilize after pouring, and the strain of vertical bar and horizontal bar decreases obviously after 24 hours of concrete maintenance.Then it remained stable.It shows that with the development of concrete strength, the beam and slab can bear part of the deadweight, thus reducing the load of the bracing system.In addition, scissors bracing and hoop play an important role in the stability of formwork bracing system.The field test results can be used as reference for the design and application of fastener high formwork support system.
