轻型木结构建筑胶合板覆板的握钉力性能

Nail-holding Performance of Larch Plywood Sheathing in Light Frame Construction

介绍轻型木结构覆板垂直拔出力和平行侧向压力2种握钉力性能的试验装置和方法,并进行国产人工林落叶松胶合板覆板的握钉力性能试验。结果表明:与国外胶合板覆板具有相同厚度的国产人工林落叶松墙面板、屋面板和楼面板,其握钉力性能均超出标准规定的技术指标值。

Test devices, conditions and methods for nail-holding performance testing under lateral and vertical drawn loads for sheathing panels in light frame construction were introduced. The performance of plantation grown Chinese Larch （Larix gmelini） plywood, which could be used as wall, roof and flooring panels in light frame construction, was also studied. It was found that the Larch plywood, with the same thickness as foreign plywood products, had superior performance with nail-holding power under both lateral and vertical drawn loads as compared with the requirements for the related standards.
