本文系根据赴日本建筑考察的见闻和部分资料整理成的,供国内施工部门参考。1.模板固定器日本木模板多采用经浸油处理的9～11层木夹板,加劲肋用钢管。为了节约木材,减少损耗,拼装模板时使用模板固定器,不用钉子。固定器由间隔棒、木制或塑料锥体、螺栓棒和扣紧片等部件组成(图1)。间隔棒为保持模板内部尺寸距离之用,有塑料和钢制两种。间隔棒打入混凝土后不再拆除。锥体有丝扣,用来固定螺栓棒。塑料锥体打入混凝土内不再拆除,木制锥体用特殊工具挖除。锥体留下的孔洞用砂浆填平。外露的
This article is based on the information of the construction inspections in Japan and some of the information compiled for the reference of the domestic construction sector. 1. Template retainers Japanese wood formwork mostly uses 9-11-story wood splints treated with oil-impregnated and stiffened ribs. In order to save wood and reduce wear, the template holder is used when assembling the template without nails. Fixtures consist of spacers, wooden or plastic cones, bolts, and fastening tabs (Figure 1). Spacers are used to keep the internal dimensions of the formwork in both plastic and steel versions. The spacers will not be dismantled once they have been driven into concrete. The cone has a screw thread for fixing the bolt rod. Plastic cones are no longer dismantled into concrete and wooden cones are removed with special tools. The hole left by the cone is filled with mortar. Exposed
