硅pu球场施工工艺新标准
作者:管理员    发布于:2018-01-08 12:29:43    文字:【】【】【

硅pu球场材料由于它的恬静性,振转动性,耐磨性,粘合强,持久耐用性,抗污性等较好的优势性能,从弹性丙烯酸群中脱颖而出。今天简单地给大家一下硅pu球场施工工艺新标准。


1、防水层:丙烯酸篮球场基础下方必须做气障(防水层),避免涂料面层产生砂眼、起泡甚至剥离;伸缩缝:伸缩缝只可设一条,即中网下方之球场中心线,赛区线内不可设置伸缩缝;平整度:用3m直尺任一方向两点间高差不超过3mm。水泥表面不能粗糙。


2、添加剂:水泥混凝土建造和养护中不可使用固化剂及硬化剂。裂缝:水泥混凝土开裂难以避免,头发丝细缝不影响打球,但应避免结构性开裂。伸缩缝及裂缝需先进行补缝处理:将单组分聚氨脂材料838注入裂缝内,抹平。


3、排水:整个球场应有5‰的排水坡度。排水方向平行于中网方向一边排水;养护:基础做好后至少养护8天;表面:水泥面收浆时用扫帚或木板拖动拉毛,勿用铁铲熨平。
