Construction technology of space torsion curved surface wood grain bare concrete wall surface
The invention provides a construction technology of a space torsion curved surface wood grain bare concrete wall surface. The construction technology specifically comprises the following steps of making a concrete test block, and performing strength inspection; hardening a foundation in the range of 4-5 m outside a construction structure; refining a curved surface by adopting a scheme of replacing a curve with a straight line to perform surveying and setting out; designing and building a support system according to the structural characteristics of the curved surface; comparing, selecting and designing a template scheme; processing an outer-layer plywood formwork and an inner-layer wood grain formwork, and performing formwork installation on the support system according to a measured and positioned contour line; reserving a pouring vibration hole in the formwork on the upper side of the curved surface; binding steel bars in the area between the formworks, and pouring concrete while proper vibration is conducted; after the concrete is solidified, gradually dismantling the outer-layer plywood formwork and the inner-layer wood grain formwork; and performing concrete wood grain appearance protection and repair after the structure is formed. According to the construction technology, process optimization is carried out in the aspects of surveying and setting out, support formwork erection, steel bar binding, concrete pouring and curing and the like, and the apparent quality of the space torsion curved surface wood grain bare concrete is integrally improved.
本发明提供了一种空间扭转曲面木纹清水混凝土墙面施工工艺，具体包括以下步骤：制作混凝土试块并进行强度检验；在施工结构外侧4～5m范围硬化地基；采用以直代曲方案细化曲面进行测量放线；根据曲面的结构特征设计并搭建支架体系；比选并设计模板方案；加工外层胶合板模板、内层木纹模板，并根据测量定位的轮廓线在支架体系上进行模板安装；在曲面上侧模板位置预留浇筑振捣孔；在模板之间的区域绑扎钢筋并浇筑混凝土，浇筑时适当振捣；待混凝土凝固后逐步拆除外层胶合板模板和内层木纹模板；待结构成型后进行混凝土木纹外观保护及修复。本发明在测量放线、支架模板搭设、钢筋绑扎、混凝土浇筑与养护等方面进行工艺优化，整体提升空间扭转曲面木纹清水混凝土的表观质量。
