“绿慧”牌正交胶合木(CLT)建筑预制板系列产品研发成功

正交胶合木(CLT)是通过把厚度为15-35mm规格的锯材等单元通过干燥、分等、表面加工、铺层、涂胶、纵横交错层积和加压胶合等工序而制成的新型大幅面装配式建筑预制型板材, 该产品填补了中国国内空白。我们的竹木复合CLT专利新产品可充分发挥竹木各自的优势, 性价比更高, 属世界首创。

  正交胶合木(CLT)CLT预制板轻质高强, 可充分发挥木材强重比高的优势,板材幅面大, 厚度可至300mm, 在工厂很容易实现模块化生产, 预制成墙板、楼板、屋面板及各类特殊要求的板材,实现各类建筑的现场组装和装配式建造。CLT与传统钢筋混凝土相比, 重量轻约4-6倍, 作墙体材料时厚度可缩小约1/3。

  Cross-laminated timber (CLT) is an innovative prefabricated building product manufactured by laminating dimensional lumber (15-35 mm thick) with adjacent layers oriented at 90° to each other. Ningbo Sino-Canada Low-Carbon Technology Research Institute Co. Ltd. is the first company inChinawhich has successfully developed this product. CLT, as a large-dimension massive timber product with high strength and light weight, can be prefabricated in the mill and assembled on the construction site as wall, floor, and roof materials. Compared to traditional steel and concrete, CLT is 5-6 times lighter, and the thickness of wall can be 1/3 less when CLT is used.
