| 摘 要： | 在包装、家具框架中L型构件是一种比较常见的结构形式.本文通过分析跨距对木塑L型构件结构强度和连接结构强度的影响,得出以下结论:跨距对木塑L型构件结构强度的影响非常显著,跨距越短,结构强度越大;跨距对连接结构强度影响也很大,跨距在190mm左右时,连接性能最好.

| Abstract: | The L-type of outdoors furniture frames and rails frames is a common structural pattern. This paper studied the effect of span on the strength of WPC L-type structure and its joint. The results were very significant and showed that the shorter of the span, the stronger of the structure, and the span have important effects on the strength of the joint structure. The joint property is best when the span is about 190mm. |
