预应力钢筋混凝土挂瓦板,作为屋面基层结构,具有耐久、防火、隔热、保温等优点,并能节约大量木材。而且下表面平整、美观,只需加以补缝刷自,即可代替室内天棚。可广泛地用于民用、公共建筑物和不受动荷载振动影响的工业建筑。近两年来,我们在某仓库群(均为18米跨度,一楼一底混合结构)施工中.产生了6米长预应力钢筋混凝土挂瓦板3000多块(图1),共计12000平米以上。从生产、堆放、运输(山区碎石路面,汽车运输,运距约30公里)到吊装、盖瓦、室内勾缝刷白完毕, Prestressed reinforced concrete hanging tile, as a roof base structure, has the advantages of durability, fire prevention, heat insulation, heat preservation, etc., and can save a lot of wood. Moreover, the lower surface is flat and beautiful, and it only needs to be repaired with a brush to replace the indoor ceiling. It can be widely used in civil, public buildings and industrial buildings that are not affected by the impact of dynamic loads. In the past two years, we have produced more than 3,000 pieces of 6-meter-long prestressed reinforced concrete hanging tiles in a warehouse group (each with 18-meter span and mixed structure on the first floor and one floor) (Figure 1), totaling more than 12,000 square meters. . From production, stacking and transportation (mountain gravel roads, automobile transportation, transport distance of about 30 km) to hoisting, tiling, and interior finishing,
