线坠是建筑安装行业中用量最大,使用最频繁的测量工具之一。为了提高垂直度测量的操作效率,确保施工质量,由北京市设备安装工程公司研制成功、上海县颛桥机械厂生产的磁座线坠,经多年现场施工使用,效果良好,深受广大施工人员和质量检查人员的欢迎。已在国内各省市的建筑安装单位普遍使用。磁座线坠有3.5米和5米两种规格。3.5米磁座线坠测量钢结构或钢铁金属部件的垂直度,并在它的壳内装有水平和垂直两个方向的水泡,所以又可作为一个小的水平仪,较为直观地观察被测物体的水平度及垂直度。另一种5米磁座线坠不但能测量钢铁部件的垂直度,因它带有一个弹簧针,所以还可以测量木制件的垂直度。它们的外形结构与钢卷尺
The pendant is one of the largest and most frequently used measurement tools in the construction and installation industry. In order to improve the operation efficiency of verticality measurement and ensure the construction quality, the magnetic seat line pendant produced by the Beijing Equipment Installation Engineering Co., Ltd., which was produced by Shanghai Shiqiao Machinery Factory, has been used successfully for many years and has been widely used by construction workers. Quality inspection staff welcome. It has been widely used by construction and installation companies in various provinces and cities in China. The magnetic seat line has two specifications of 3.5 meters and 5 meters. The 3.5-meter magnetic stand line sinker measures the verticality of the steel structure or steel metal parts, and has blisters in both horizontal and vertical directions in its shell, so it can be used as a small level meter to observe the measured object more intuitively. Level and verticality. Another type of 5-meter magnetic seat line sinker not only measures the verticality of steel parts, but also has a spring pin so it can measure the verticality of wooden parts. Their shape structure and steel tape measure
