清水混凝土耐久性变曲率连环拱体结构施工技术与应用

Construction Technology and Application for Continuous Variable Curvature Arch Structure of Fair-faced Concrete with Durability Variable Curvature

在某博物馆项目清水混凝土耐久性变曲率连环拱体结构施工中,采用恰当的混凝土配合比和浇筑方法,把木夹板弯成变曲率模板,并利用模板安装的拼缝和螺栓孔眼布置,使其结构线条顺畅、平整圆滑,达到了清水混凝土耐久性效果。

In the construction of continuous variable curvature arch structure of fair-faced concrete with durability variable curvature for one museum project,the right appropriate of mix proportion design of concrete and its pouring construction method can be used in the plywood which formed the formwork construction technique for controlling the shape of variable curvature arch and fully utilizated the seam and bolt hole layout of the formwork installation,so as to make structural lineament become smoothly and level flat with putty and bring the desired result of fair-faced concrete with durability.
