我们在安装某机库的大门时,按设计要求采用30毫米厚的橡胶板作防撞垫。但因工地无专用的橡胶切割设备,一般的钢锯因锯齿太细,切割时易发热和粘锯,所以,切割很困难。经过试验,我们采用了木工使用的普通刀锯,因刀锯锯齿间距较大,事前应将锯齿伐成双刀刃形(如图),使用时往锯上浇些水,就可以很方便 When we installed the door of a hangar, we used a 30 mm thick rubber plate as a crash pad as designed. However, because there is no special rubber cutting equipment for the construction site, the general hacksaw is too fine for sawing, and is prone to heat and sticking when cutting. Therefore, cutting is difficult. After the experiment, we used the ordinary knife saw used by woodworking. Because the saw tooth spacing of the saw blade is large, the saw tooth should be cut into a double knife blade beforehand (as shown in the figure). When you use it, you can put some water on the saw and it is very convenient.
