建筑工程中的某些曲面钢筋混凝土结构(如曲面墙体、桥墩、柱等)和一般高耸钢筋混凝土构筑物(如贮仓、筒塔等)在施工时都需要曲面模板。我国目前常用于曲面结构施工的有木楼板(如用木板拼接圆柱模板)和钢模板体系(如柔性模板、双曲可凋模板)。国外常用于曲面结构施工的模板体系较多,如美国西门子公司的全钢预弯模板、经济模板公司的预制半径可凋模板、日本的曲面组合钢模板和一些国家的对开式圆柱模板等。曲面模板本身可互相拼装,也可与平面模板配合拼装成不同曲率的曲面,以用于各种曲率的曲面结构的施工。本文简要介绍目前国内外常用于曲面结构施工的几种模板系
Some curved surface reinforced concrete structures (such as curved walls, piers, pillars, etc.) and general towering reinforced concrete structures (such as silos, tube towers, etc.) in construction projects require curved formwork during construction. China is now commonly used in the construction of curved structures with wood floors (such as the use of wood panels spliced cylindrical template) and steel template system (such as flexible template, hyperbolic can be withered template). There are many template systems commonly used in the construction of curved structures abroad, such as the pre-bending templates of Siemens Corporation of the United States, the prefabricated radiuses of the economic template company, the curved surface of the steel template of Japan, and the template of split cylindrical columns of some countries. The surface template itself can be assembled with each other, and can also be assembled with a planar template to form curved surfaces with different curvatures for use in the construction of curved structures with various curvatures. This article briefly introduces several kinds of template systems commonly used in the construction of curved structures at home and abroad.
