上海分公司一种建筑施工墙体开槽工具获得实用新型专利授权
发布日期:2019-03-29

近日,中国建筑第二工程局有限公司所属上海分公司研发的“一种建筑施工墙体开槽工具”成果获实用新型专利授权娱乐app彩票-娱乐彩票ios版下载。

目前市场现有的建筑施工墙体的开槽工具在使用过程中存在一些缺陷,例如调节开槽深度方式复杂,而且在开槽时工具与毛坯墙面摩擦容易影响开槽精度。

在此背景下娱乐app彩票-娱乐彩票ios版下载,本建筑施工墙体开槽工具应运而生。通过深度调节螺母、丝杠、固定套娱乐app彩票-娱乐彩票ios版下载、伸缩套和深度底板使其正转和反转娱乐app彩票-娱乐彩票ios版下载,以实现深度底板位置调节的目的,便于根据实际需要调节开槽深度。同时,利用开槽线推动该开槽工具娱乐app彩票-娱乐彩票ios版下载,使刀片位于深度底板的限位槽内部,保证刀片转动切割时不会因晃动而产生偏移娱乐app彩票-娱乐彩票ios版下载,影响开槽精度娱乐app彩票-娱乐彩票ios版下载。目前该成果已成功应用于徐州万科项目娱乐app彩票-娱乐彩票ios版下载。(柳晓琴 方自强)
