利用玻璃钢复合材料研制成功的煤矿立井井筒梯子间系列产品已投入使用。用玻璃钢复合材料可以做成梯子间的小梁、人行梯、支撑座、平台板等。这种梯子间材料除具有高度耐腐特点外,还保留了原钢结构的性能,不但减少了因腐蚀而增加的维修和更换次数,同时节省了大量钢材和因维修、更换造成的停产损失。由于重量轻,便于安装施工,减轻了安装工人的劳动强度,工程进度比金属构件施工快一倍。
The use of glass fiber reinforced plastic composite materials successfully developed shaft mine shaft ladders series of products have been put into use. With FRP composite materials can be made of trabecular ladder, pedestrian ladder, support base, plate and so on. In addition to its high corrosion resistance, this ladder material preserves the performance of the original steel structure. This reduces the number of repairs and replacements due to corrosion and saves a large amount of steel and loss of production due to maintenance and replacement. Light weight, easy to install and reduce the labor intensity of installation workers, construction progress twice as fast as metal construction.
