平板玻璃钢圆柱模板及其制作方法和施工工艺
摘要：
一种平板玻璃钢圆柱模板及其制作方法和施工工艺，该模板具有开合韧性、厚度均匀的玻璃钢板体和连接螺栓，其玻璃钢板体具有展开和闭合两种形态，即出厂时的平板形态和使用时的圆筒形态，其玻璃钢板体的两侧边、即闭合边是同向折边，折边的内侧面固定连接通长金属条片或/和海绵条片，折边外侧面固定连接角钢，折边上间隔分布有连接孔，并由闭口螺栓连接。上述平板玻璃钢圆柱模板的施工工艺包括支模准备、柱模定位、柱模围合、垂直调整、混凝土浇筑、拆模。模板的制作是以一个整体平台为制作底面，在平台内可制作不同尺寸的玻璃钢平板，不必制作不同的圆柱形模具，具有重量轻、施工速度快、运输方便、节省模具胎心制作费用、降低工程造价等优点。
摘要（英）：

The cylindrical formwork has GRP plate with opening and closing toughness and homogeneous thickness, and connecting screw bolts. The GRP plate has two states, that is, the plate state in delivery and the cylindrical state in use. The side edges for closing of the GRP plate are hemmed in the same direction and have long metal or sponge strips in the inner side of the hems, connecting angle steelfixed to the outer side of hems and connecting holes for the connecting screw bolts. The construction process with the cylindrical formwork includes preparation, locating the formwork, encircling, vertical adjustment, depositing concrete and demolding. When the formwork is produced, one integral platform is used as the base and GRP plates, rather than cylindrical formworks, in different sizes are produced. The present invention can reduce formwork core making cost and lower engineering cost.
