我厂学习了河南省新乡市砖瓦公司用席盖苫架的经验,经过一年来的使用证明:它的防护能力强,便于操作,经久耐用;而且可以利用旧席或其他代用品做,这在当前席子供应不足的情况下更有现实意义。席盖的做法是:两层席相合,顶部两层席之间夹层油纸。用六片2.2公尺长4公分宽弯成倒U 字形的竹片里外相夹,作为中间和两端的三个骨架,另用同样宽的六片竹片夹在圆顶中间和两边下脚,作为三个横骨架;横架夹立架,横立相交处用钉子钉紧(形式、规格如图)。 Our factory has learned the experience of using the cover truss for the brick and tile company of Xinxiang City, Henan Province. After one year of use, it has proved that it has strong protection capabilities, is easy to operate, and is durable; it can also be made using old seats or other substitutes. In the current situation of insufficient supply of mats is more realistic. The practice of the cover is: two layers of seats, sandwiched between the top two layers of oiled paper. Using six pieces of bamboo 2.2 meters long and 4 centimeters wide and bent into an inverted U-shaped bamboo clip inside and outside, as the middle and both ends of the three skeletons, and the other with the same width of six bamboo clips in the middle of the dome and on both sides of the feet as Three horizontal skeletons; the horizontal shelf is clamped and the horizontal intersection is nailed tightly (forms and specifications are shown in the figure).
