方圆木圆柱模板真正优质桦杨木为原料,采用圆模施工,宜按提升单元进行。除应满足滑模工艺的有关要求外,宜连续施工,并应按柱的混凝土强度实际增长情况,控制滑模速度;当柱高度与截面较小边长之比大于或柱高度超过时,应有可靠的稳定措施;采用升模施工,其浇筑位置、操作平台、柱模及脚手架的设计,由现浇柱的每次施工高度确定,并不应妨碍提升机的正常运转。

圆柱木模板,圆柱子模板

圆柱模板与胎模之间及板与板之间必须做隔离层。隔离层可采用涂刷或铺贴式材料。银河娱乐注册送彩金隔离层材料应具有防水性、耐磨性,且易于清除。密肋板施工,可用塑料、金属等工具式模壳、预制混凝土芯模,或用轻质材料填充;格梁板施工,尚可采用预制钢筋混凝土芯模或定型组合圆柱模板。

在各层板四周的外侧,要支好边模,在其下部每隔适当位置应留出排水孔,避免隔离层被水浸泡;板的各种预留孔洞应按划线预留,并在浇筑混凝土前校正。当预留孔拆模后,采取可靠措施,以防浇筑上一层板时灌入混凝土堵塞。
